作為所述拉鏈用鏈牙成形裝置的一例，有如下者，即，為了對鏈牙用線材進行剪切加工，而具備能夠相對地滑動的切斷模具及切斷衝頭（專利文獻1）。剪切加工是自切斷模具側朝向切斷衝頭側供給鏈牙用線材，使切斷衝頭自鏈牙用線材的前端部的頭部側相對地接近，並藉由切斷衝頭與切斷模具共同地對鏈牙用線材的前端部進行剪切，從而製造鏈牙用原材料。 切斷衝頭90如圖11所示，具備相對於未圖示的切斷模具的滑動接觸面90a、及對未圖示的鏈牙用線材進行剪切的刀面90b。而且，刀面90b為與滑動接觸面90a正交的面。In an example of the fastener element molding device, a cutting die and a cutting punch that can slide relative to each other are provided in order to perform shear processing on the element wire for a fastener (Patent Document 1). In the shearing process, the wire for the element is supplied from the cutting die side toward the cutting punch side, and the cutting punch is relatively close to the head side of the tip end portion of the element wire, and the punch is cut by The cutting die collectively cuts the front end portion of the element wire for the element to manufacture a material for the element.

[先前技術文獻] [專利文獻] [專利文獻1]中國專利申請案公開103386448號說明書 [專利文獻2]中國實用新型第204686168號說明書[Prior Art Document] [Patent Document] [Patent Document 1] Chinese Patent Application Publication No. 103386448 (Patent Document 2) Chinese Utility Model No. 204686168
[發明所欲解決之課題] 且說，若進行剪切加工，則於鏈牙用線材中的與刀面碰撞的部分轉印有刀面的形狀。而且，所述任一切斷模具均使刀面為與滑動接觸面正交的面，因而鏈牙原材料中的與刀面碰撞的部分為與鏈牙原材料的厚度方向正交的垂直面。[Problems to be Solved by the Invention] When the shearing process is performed, the shape of the blade surface is transferred to the portion of the element for strands that collides with the blade surface. Further, in any of the cutting dies, the blade surface is a surface orthogonal to the sliding contact surface, and thus the portion of the element material that collides with the blade surface is a vertical surface orthogonal to the thickness direction of the element material.
拉鏈用鏈牙成形裝置亦如專利文獻1記載般，於剪切加工後進行塑性加工，相對於鏈牙原材料的頭部而成形嚙合凸部與嚙合凹部。該塑性加工時，具備所述垂直面的鏈牙原材料因與塑性加工中使用的成形模具的摩擦阻力的關係，有時會使成形模具的耐久性劣化。詳細而言為以下所示。As described in Patent Document 1, the fastener element forming device for zipper is plastically processed after shearing, and the engaging convex portion and the engaging concave portion are formed with respect to the head portion of the element material. In the plastic working, the fastener element having the vertical surface may deteriorate the durability of the molding die due to the frictional resistance of the molding die used in the plastic working. The details are as follows.
拉鏈用鏈牙成形裝置如專利文獻1記載般，包括：成形模具（forming die），能夠相對於切斷衝頭相對地滑動並且收容鏈牙原材料；成形衝頭，能夠相對於成形模具相對地往復移動並且壓入鏈牙原材料的頭部；以及壓力墊（pressure pad），能夠相對於成形模具相對地往復移動並且壓住鏈牙原材料。As described in Patent Document 1, the fastener element forming device includes a forming die that can slide relative to the cutting punch and accommodate the element material, and the forming punch can be relatively reciprocated with respect to the forming die. Moving and pressing into the head of the element of the element; and a pressure pad capable of relatively reciprocating relative to the forming die and pressing the element of the element.
更詳細而言，成形模具92如圖12所示，具備成形模部93，成形模部93相對於其滑動接觸面92a凹陷並且收容鏈牙原材料99。成形模部93具備：與鏈牙原材料99的頭部99a的厚度方向相向的底面93a，及與和深度方向正交的方向相向並且與鏈牙原材料99的垂直外周面99c接觸的內周面93b，使內周面93b的下部與底面93a的後部朝向下方而形成前端變細的斜面93c。而且，壓力墊94於成形衝頭壓入鏈牙原材料99時，嵌入至鏈牙原材料99的一對腳部99b、腳部99b之間。 塑性加工時鏈牙原材料99如圖12至圖13所示，朝向成形模具92的成形模部93壓入，此時鏈牙原材料99的外周面的下側的角部99d與成形模部93的斜面93c碰撞，因而成形模具92會因磨損而受損。More specifically, as shown in FIG. 12, the molding die 92 includes a molding die portion 93, and the molding die portion 93 is recessed with respect to the sliding contact surface 92a thereof and accommodates the element material 99. The molding die portion 93 includes a bottom surface 93a that faces the thickness direction of the head portion 99a of the element material 99, and an inner circumferential surface 93b that faces the direction orthogonal to the depth direction and that is in contact with the vertical outer circumferential surface 99c of the element material 99. The lower portion of the inner peripheral surface 93b and the rear portion of the bottom surface 93a are directed downward to form a slope 93c having a tapered front end. Further, the pressure pad 94 is fitted between the pair of leg portions 99b and the leg portions 99b of the element raw material 99 when the forming punch presses the element raw material 99. As shown in FIGS. 12 to 13 , the element material 99 is press-fitted into the molding die portion 93 of the molding die 92 at the time of plastic working. At this time, the lower corner portion 99d of the outer peripheral surface of the element material 99 and the molding die portion 93 are formed. The inclined surface 93c collides, and thus the forming mold 92 is damaged by abrasion.
本發明鑒於所述實際情況而創作，其目的在於將鏈牙原材料的形狀設為可提高成形模具的耐久性的形狀，換言之，將剪切加工中使用的切斷衝頭的刀面的形狀設為可儘可能地抑制成形模具的磨損的形狀。The present invention has been made in view of the above-described circumstances, and an object of the present invention is to provide a shape of a fastener element as a shape capable of improving the durability of a molding die, in other words, a shape of a blade surface of a cutting punch used in a shearing process. It is a shape that can suppress the wear of the forming mold as much as possible.
[解決課題之手段] 本發明的拉鏈用鏈牙成形裝置的切斷衝頭包括刀部，所述刀部與切斷模具共同地將使一對腳部自頭部分支為兩股的形狀的鏈牙用線材剪切，且所述刀部能夠相對於切斷模具相對地沿第一直線方向滑動。刀部包括：與切斷模具滑動接觸的滑動接觸面，及與滑動接觸面交叉的刀前端面。刀前端面包括刀面，所述刀面將沿與滑動接觸面正交的第二直線方向中自切斷模具側朝向刀部側的方向供給的鏈牙用線材，自該鏈牙用線材的頭部側剪切。自第二直線方向觀察，刀面包括斜面，所述斜面呈為了與頭部及一對腳部碰撞而凹陷的凹形狀，並且使凹形狀隨著遠離所述滑動接觸面側而擴大。此外，自第二直線方向觀察，與滑動接觸面為相反側的凹形狀的周向上的全部存在於與滑動接觸面側的凹形狀一致的基準位置與較基準位置靠外側的位置的範圍內。[Means for Solving the Problem] The cutting punch of the fastener element forming device for a slide fastener according to the present invention includes a blade portion which, in combination with the cutting die, has a shape in which a pair of leg portions are branched from the head into two. The element is cut with a wire, and the blade is slidable relative to the cutting die in a first straight direction. The blade portion includes a sliding contact surface that is in sliding contact with the cutting die, and a blade front end surface that intersects the sliding contact surface. The front end surface of the blade includes a blade surface, and the blade surface is supplied with a wire for supplying the element in a direction from the cutting die side toward the blade side in a second linear direction orthogonal to the sliding contact surface, from the wire for the element Head side shear. Viewed from the second straight line direction, the blade surface includes a sloped surface having a concave shape recessed to collide with the head portion and the pair of leg portions, and the concave shape is enlarged as being away from the sliding contact surface side. Further, all of the circumferential directions of the concave shape on the opposite side to the sliding contact surface are present in a range from the reference position corresponding to the concave shape on the sliding contact surface side to the position outside the reference position as viewed from the second straight line direction.
而且，自製作切斷衝頭的加工的容易性的方面而言，較佳為如下。 即，自第二直線方向觀察，與滑動接觸面為相反側的凹形狀的周向上的至少一部分因斜面而存在於較基準位置靠外側的位置。Further, from the viewpoint of easiness of processing for cutting the punch, it is preferably as follows. In other words, at least a part of the circumferential direction of the concave shape opposite to the sliding contact surface is present at a position outside the reference position due to the inclined surface as viewed in the second straight line direction.
斜面無論設置於刀面上的哪一個位置均可。然而，於將頭部收容於成形模部，且在頭部成形嚙合凸部與嚙合凹部時，為了儘可能地抑制成形模部的損傷，理想為如下。 即，刀面包括：與頭部碰撞的頭部碰撞面，及與一對腳部碰撞的一對腳部碰撞面，斜面設置於頭部碰撞面。The bevel can be placed at any position on the blade surface. However, when the head portion is housed in the molding die portion and the engaging convex portion and the engaging concave portion are formed in the head portion, it is preferable to suppress the damage of the molding die portion as much as possible. That is, the blade surface includes a head collision surface that collides with the head, and a pair of leg collision surfaces that collide with the pair of leg portions, and the slope surface is provided on the head collision surface.
斜面無論設置於刀面中的第二直線方向上的哪個位置均可，但理想為如下。 即，斜面設置於刀面中的第二直線方向的兩側中的任一側。The inclined surface may be located at any position in the second straight line direction in the blade surface, but is preferably as follows. That is, the inclined surface is provided on either one of the two sides in the second straight direction in the blade surface.
[發明的效果] 根據本發明，因剪切時於鏈牙用線材中轉印有作為刀面的形狀的一部分的斜面，故自鏈牙用線材切斷的鏈牙原材料的形狀於其外周面亦具備斜面，從而外周面中的切斷模具側的角部的強度減弱了與斜面相當的量。因此，剪切加工後，在鏈牙原材料成形嚙合凸部及嚙合凹部時，與現有的不具有斜面的鏈牙原材料相比，具備斜面的鏈牙原材料能夠減小與塑性加工中使用的成形模具的成形模部碰撞時的衝擊，從而成形模具的耐久性提高。[Effects of the Invention] According to the present invention, since the inclined surface which is a part of the shape of the blade surface is transferred to the element wire for the element during the cutting, the shape of the element material cut from the element for the element is on the outer peripheral surface thereof. There is also a slope so that the strength of the corner portion on the side of the cutting die in the outer peripheral surface is weakened by an amount corresponding to the slope. Therefore, when the mesh material is molded into the engaging convex portion and the engaging concave portion after the shearing process, the element material having the inclined surface can be reduced and the forming mold used in the plastic working can be used as compared with the conventional element material having no inclined surface. The impact of the forming die at the time of collision causes the durability of the forming die to be improved.

The pair of leg collision surfaces 26b and the leg collision surface 26b have a shape in which the left and right intervals W2 are narrowed from the front end toward the rear end.
而且，刀面26具備斜面26p，該斜面26p自上下方向觀察，隨著遠離切斷模具22側而擴大凹形狀，即隨著朝向上方而擴大凹形狀。圖3的例中，斜面26p自上下方向觀察，遍及刀面26的凹形狀的整個周圍而形成。換言之，自上下方向觀察，斜面26p跨及頭部碰撞面26a、一對腳部碰撞面26b、腳部碰撞面26b的整個區域而形成。因此，滑動接觸面25a的相反側，即上端的凹形狀26t的全部，存在於較與滑動接觸面25a側，即下端的凹形狀26s一致的基準位置稍靠外側的位置。附帶說，上端的凹形狀26t為稍小於鏈牙用線材6的外形的形狀。而且，斜面26p跨及刀面26的上下方向的整個區域而形成，使頭部碰撞面26a的部分與刀面26的凹形狀的前端的間隔W1朝向上方擴大，使一對腳部碰撞面26b、腳部碰撞面26b的部分的左右的間隔W2隨著朝向上方而擴大。 另外，斜面26p的角度θ如圖1、圖2所示，為相對於上下方向1度～45度的範圍。Further, the blade surface 26 is provided with a sloped surface 26p which is enlarged from the side of the cutting die 22 as viewed from the vertical direction, that is, the concave shape is enlarged as it goes upward. In the example of Fig. 3, the inclined surface 26p is formed over the entire circumference of the concave shape of the blade surface 26 as viewed in the vertical direction. In other words, the inclined surface 26p is formed across the entire area of the head collision surface 26a, the pair of leg collision surfaces 26b, and the foot collision surface 26b as viewed in the vertical direction. Therefore, the opposite side of the sliding contact surface 25a, that is, the concave shape 26t at the upper end, exists at a position slightly outside the reference position on the sliding contact surface 25a side, that is, the concave shape 26s at the lower end. Incidentally, the concave shape 26t at the upper end is a shape slightly smaller than the outer shape of the wire 6 for the element. Further, the inclined surface 26p is formed over the entire area in the vertical direction of the blade surface 26, and the interval W1 between the portion of the head collision surface 26a and the concave end of the blade surface 26 is enlarged upward, and the pair of leg collision faces 26b are formed. The left-right interval W2 of the portion of the leg collision surface 26b is enlarged as it goes upward. Further, the angle θ of the inclined surface 26p is a range of 1 to 45 degrees with respect to the vertical direction as shown in FIGS. 1 and 2 .
切斷衝頭24的第二例如圖4所示，刀面26與切斷衝頭24的第一例不同。刀面26除斜面26p外，具備與滑動接觸面25a垂直的垂直面26q（與上下方向平行的面）。斜面26p形成於刀面26的下端部，垂直面26q形成於刀面26中的較斜面26p靠上側的整個區域。The second cutting of the punch 24, as shown in Fig. 4, is different from the first example of the cutting punch 24. The blade surface 26 includes a vertical surface 26q (a surface parallel to the vertical direction) perpendicular to the sliding contact surface 25a except for the inclined surface 26p. The inclined surface 26p is formed at the lower end portion of the blade surface 26, and the vertical surface 26q is formed over the entire upper surface of the blade surface 26 on the upper side of the inclined surface 26p.
切斷衝頭24的第三例如圖5所示，刀面26與切斷衝頭24的第一例不同。刀面26除斜面26p外亦具備垂直面26q。垂直面26q形成於刀面26的下端部，斜面26p形成於刀面26中的較垂直面26q靠上側的整個區域。附帶說，切斷衝頭24的第一例至第三例，均僅由斜面26p、或僅由斜面26p與垂直面26q形成刀面26，因而製作刀面26時容易加工。The third of the cutting punch 24 is different from the first example of the cutting punch 24, as shown in FIG. 5, for example. The blade surface 26 also has a vertical surface 26q in addition to the slope 26p. The vertical surface 26q is formed at the lower end portion of the blade surface 26, and the inclined surface 26p is formed over the entire region of the upper surface 26q of the blade surface 26 on the upper side. Incidentally, in the first to third examples of the cutting punch 24, the blade surface 26 is formed only by the inclined surface 26p or only the inclined surface 26p and the vertical surface 26q. Therefore, it is easy to process when the blade surface 26 is formed.
所述剪切加工部2按照以下的1）～3）的步驟來剪切鏈牙用線材6。 1）鏈牙用線材6以相當於一個鏈牙原材料7的厚度自切斷模具22的滑動接觸面22a向上方突出。而且，此時沖柱20設為限制前進的位置。 2）沖柱20自限制前進的位置後退。如此，切斷模具22及頭部加工部3的一部分（後述的成形模具30）與沖柱20一起後退。 3）在沖柱20的後退中，切斷衝頭24的刀面26與鏈牙用線材6的上端部碰撞，切斷模具22與切斷衝頭24共同地將鏈牙用線材6的上端部剪切，從而鏈牙原材料7被切斷。 該剪切時，切斷衝頭24的刀面26的形狀（頭部碰撞面26a、一對腳部碰撞面26b、腳部碰撞面26b的形狀）被轉印至鏈牙原材料7。若為切斷衝頭24的第一例的情況，則鏈牙原材料7的頭部7a的外周面中的後表面整個區域成為自下端朝向上端而逐漸朝向後方的斜面7p（參照圖6）。而且，雖未圖示，鏈牙原材料7的頭部7a的外周面中的整個左側面與左側的腳部的整個左側面成為自下端朝向上端而逐漸朝向左方的斜面，鏈牙原材料7的頭部7a的外周面中的整個右側面與右側的腳部的整個右側面成為自下端朝向上端而逐漸朝向右方的斜面。因此，鏈牙原材料7的外周面中的切斷模具22側（下側）的角部7z的強度，例如與將該外周面設為垂直面的情況相比，減弱了與斜面7p相當的量。另外，不限於切斷衝頭24的第一例的情況，在為第二例、第三例的情況下，例如與將該外周面設為垂直面的情況相比，角部7z的強度亦減弱了與斜面7p相當的量。經如此剪切的鏈牙原材料7接下來利用頭部加工部3而加工。The sheared portion 2 cuts the element 6 for the element according to the following steps 1) to 3). 1) The element wire 6 for the element is protruded upward from the sliding contact surface 22a of the cutting die 22 in a thickness corresponding to one element material 7. Further, at this time, the punch 20 is set to a position that restricts the advancement. 2) The punch 20 is retracted from the position where the advancement is restricted. In this manner, a part of the cutting die 22 and the head processing portion 3 (a molding die 30 to be described later) is retracted together with the punch 20 . 3) In the retreat of the punching column 20, the blade surface 26 of the cutting punch 24 collides with the upper end portion of the element wire 6 and the cutting die 22 and the cutting punch 24 collectively connect the upper end of the element wire 6 The part is cut so that the element 7 of the element is cut. At the time of this cutting, the shape of the blade surface 26 of the cutting punch 24 (the shape of the head collision surface 26a, the pair of leg collision surfaces 26b, and the leg collision surface 26b) is transferred to the element material 7. When the first example of the punch 24 is cut, the entire rear surface of the outer peripheral surface of the head portion 7a of the element material 7 is a slope 7p that gradually faces rearward from the lower end toward the upper end (see FIG. 6). In addition, the entire left side surface of the outer peripheral surface of the head portion 7a of the element material 7 and the entire left side surface of the left side leg portion are inclined surfaces that gradually become the left side from the lower end toward the upper end, and the element material 7 is not shown. The entire right side surface of the outer peripheral surface of the head portion 7a and the entire right side surface of the right side leg portion are inclined surfaces that gradually move toward the right from the lower end toward the upper end. Therefore, the strength of the corner portion 7z on the cutting die 22 side (lower side) of the outer peripheral surface of the element material 7 is reduced by the amount corresponding to the inclined surface 7p, for example, compared with the case where the outer peripheral surface is a vertical surface. . Further, the present invention is not limited to the case of cutting the first example of the punch 24, and in the case of the second example and the third example, for example, the strength of the corner portion 7z is also higher than the case where the outer peripheral surface is a vertical surface. The amount equivalent to the slope 7p is weakened. The element material 7 thus cut is then processed by the head processing unit 3.
頭部加工部3如圖8、圖10所示，包括：切斷衝頭24，亦為剪切加工部2的一部分；成形模具30，相對於切斷模具22沿前方向呈一條直線排列，並且能夠相對於切斷衝頭24沿前後方向相對滑動；成形衝頭32，相對於切斷衝頭24向前方隔開而配置，並且能夠相對於成形模具30沿上下方向往復移動；以及壓力墊34，相對於成形衝頭32向前方隔開配置，並且能夠相對於成形衝頭32沿上下方向往復移動。而且，頭部加工部3是藉由成形模具30與成形衝頭32共同地對鏈牙原材料7的頭部7a進行塑性加工，而成形出嚙合凸部7c與嚙合凹部7d，且於塑性加工時壓力墊34擠壓鏈牙原材料7的一對腳部7b、腳部7b。As shown in FIGS. 8 and 10, the head processing unit 3 includes a cutting punch 24 which is also a part of the shearing processing unit 2, and a molding die 30 which is arranged in a line in the front direction with respect to the cutting die 22. Further, it is possible to slide relative to the cutting punch 24 in the front-rear direction; the forming punch 32 is disposed to be spaced apart from the cutting punch 24, and is reciprocable in the vertical direction with respect to the forming die 30; and the pressure pad 34 is disposed to face forward with respect to the forming punch 32, and is reciprocable in the vertical direction with respect to the forming punch 32. Further, the head processing unit 3 plastically processes the head portion 7a of the element material 7 by the molding die 30 and the forming punch 32, thereby forming the engaging convex portion 7c and the engaging concave portion 7d, and during plastic working. The pressure pad 34 presses the pair of leg portions 7b and the leg portions 7b of the element material 7 .
成形衝頭32與壓力墊34能夠相對於框架沿上下方向直線往復移動地安裝。成形衝頭32如圖6所示，為沿上下方向延長的棒，且其下端部為前端變細的山形形狀（角錐形狀）。而且，壓力墊34為沿上下方向延長的棒，以該棒由一對腳部7b、腳部7b夾持的方式設定棒的左右方向的尺寸，使該棒的下端部的後表面呈階差狀凹陷，利用該凹陷的下表面34a擠壓頭部7a的上表面，利用該凹陷的後表面34b擠壓頭部7a的前表面。The forming punch 32 and the pressure pad 34 are movably reciprocally movable in the vertical direction with respect to the frame. As shown in Fig. 6, the forming punch 32 is a rod extending in the vertical direction, and its lower end portion has a mountain shape (a pyramid shape) in which the tip end is tapered. Further, the pressure pad 34 is a rod extending in the vertical direction, and the rod is sandwiched by the pair of leg portions 7b and the leg portions 7b so as to set the size of the rod in the left-right direction so that the rear surface of the lower end portion of the rod is stepped. The recessed portion is pressed by the lower surface 34a of the recess to press the upper surface of the head portion 7a, and the front surface of the head portion 7a is pressed by the recessed rear surface 34b.
成形模具30能夠相對於框架沿前後方向直線往復移動地安裝。而且，成形模具30如圖10所示，於其上表面具備相對於切斷衝頭24的滑動接觸面30a，並且於該上表面的前端部且相對於線材插通孔21而在前方處具備向下方凹陷並且收容鏈牙原材料7的成形模部31。The molding die 30 can be mounted to reciprocate linearly in the front-rear direction with respect to the frame. Further, as shown in FIG. 10, the molding die 30 has a sliding contact surface 30a with respect to the cutting punch 24 on the upper surface thereof, and is provided at the front end portion of the upper surface with respect to the wire insertion hole 21. The molding die portion 31 is recessed downward and accommodates the element material 7 of the element.
成形模具30的滑動接觸面30a與切斷模具22的滑動接觸面22a在上下方向的位置相同。 成形模部31自上方觀察與鏈牙原材料7的形狀大致一致，如圖6、圖7所示，使其前表面開口，並且使其底面31a的後部較前部低而呈階差狀地形成，並且使其底面31a的後部、後表面31b的下部及左右的側面31c、31c的下部朝向下方而成為前端變細的山形形狀（角錐狀）的斜面31d，使其後表面31b的上部及左右的側面31c、31c的上部為於上下方向平行的鉛垂面。The sliding contact surface 30a of the molding die 30 is the same position as the sliding contact surface 22a of the cutting die 22 in the vertical direction. The molding die portion 31 substantially conforms to the shape of the element material 7 as viewed from above, and as shown in Figs. 6 and 7, the front surface is opened, and the rear portion of the bottom surface 31a is formed in a stepped manner from the front portion. The lower portion of the bottom surface 31a, the lower portion of the rear surface 31b, and the lower portions of the left and right side surfaces 31c and 31c are formed downward to form a mountain-shaped (corner-shaped) slope 31d having a tapered front end, and the upper surface and the left and right sides of the rear surface 31b are formed. The upper portions of the side faces 31c and 31c are vertical faces that are parallel in the vertical direction.
所述頭部加工部3在剪切加工部2的3）的步驟之後，按照以下的4）～6）的步驟對鏈牙原材料7進行塑性加工。 4）若利用剪切加工部2剪切鏈牙原材料7後，沖柱20進一步後退，則鏈牙原材料7保持與切斷衝頭24的刀面26接觸的狀態而被擠出， 5）若沖柱20到達限制後退的位置，則鏈牙原材料7到達成形模具30的成形模部31的正上方。繼而，成形衝頭32與壓力墊34自成形模部31的上方下降，壓力墊34限制一對腳部6b、腳部6b，並且成形衝頭32將鏈牙原材料7的頭部7a朝向成形模部31的底面31a壓入。詳細而言，當利用成形衝頭32與壓力墊34的下降，鏈牙原材料7的頭部7a完全進入至成形模具30的成形模部31時，鏈牙原材料7的外周面的上端呈線狀與成形模具30的成形模部31接觸。更具體而言，如圖6所示，頭部7a的後表面的上端的整個周圍呈線狀與成形模具30的成形模部31接觸。而且，雖未圖示，但頭部7a的左右側面的上端的整個周圍、左側的腳部7b的左側面的上端的整個周圍、右側的腳部7b的右側面的上端的整個周圍呈線狀與成形模具30的成形模部31接觸。 而且，若成形衝頭32與壓力墊34進一步下降，則如圖7所示，鏈牙原材料7的外周面中的下側的角部7z碰撞到成形模部31的斜面31d，最終，頭部7a的下表面被擠壓至成形模部31的底面31a，在頭部7a形成嚙合凸部7c及嚙合凹部7d。具備斜面7p的鏈牙原材料7因其下側的角部7z的強度弱，故鏈牙原材料7的角部7z與成形模部31的斜面31d碰撞時的衝擊與現有的無斜面的鏈牙原材料相比而有所減小，因而成形模具30不易磨損，成形模具30的耐久性提高。 6）成形衝頭32與壓力墊34上升。如此形成著嚙合凸部7c與嚙合凹部7d的鏈牙原材料7接下來利用安裝加工部4加工。The head processing unit 3 plastically processes the element material 7 in accordance with the following steps 4) to 6) after the step of cutting the processed portion 2 (3). 4) When the element material 7 is cut by the shearing unit 2 and the punch 20 is further moved backward, the element material 7 is held in contact with the blade surface 26 of the cutting punch 24, and is extruded. When the punch 20 reaches the position where the restriction is retracted, the element raw material 7 reaches the directly above the forming die portion 31 of the molding die 30. Then, the forming punch 32 and the pressure pad 34 are lowered from above the forming die portion 31, the pressure pad 34 restricts the pair of leg portions 6b and the leg portions 6b, and the forming punch 32 faces the head portion 7a of the element material 7 toward the forming die. The bottom surface 31a of the portion 31 is press-fitted. In detail, when the head portion 7a of the element material 7 completely enters the molding die portion 31 of the molding die 30 by the lowering of the forming punch 32 and the pressure pad 34, the upper end of the outer peripheral surface of the element material 7 is linear. It is in contact with the forming die portion 31 of the forming die 30. More specifically, as shown in FIG. 6, the entire circumference of the upper end of the rear surface of the head portion 7a is in line contact with the molding die portion 31 of the molding die 30. Further, although not shown, the entire circumference of the upper end of the left and right side faces of the head portion 7a, the entire circumference of the upper end of the left side surface of the left leg portion 7b, and the entire circumference of the upper end of the right side surface of the right leg portion 7b are linear. It is in contact with the forming die portion 31 of the forming die 30. When the forming punch 32 and the pressure pad 34 are further lowered, as shown in Fig. 7, the lower corner portion 7z of the outer peripheral surface of the element material 7 collides with the inclined surface 31d of the forming die portion 31, and finally, the head portion The lower surface of the 7a is pressed to the bottom surface 31a of the forming die portion 31, and the engaging convex portion 7c and the engaging concave portion 7d are formed in the head portion 7a. Since the element material 7 having the inclined surface 7p has a weak strength at the lower corner portion 7z, the impact of the corner portion 7z of the element material 7 and the inclined surface 31d of the molding die portion 31 and the conventional non-beveled element material are The molding die 30 is less likely to be worn and the durability of the molding die 30 is improved. 6) The forming punch 32 and the pressure pad 34 are raised. The element raw material 7 which forms the engaging convex part 7c and the engaging recessed part 7d in this way is processed by the mounting processing part 4 next.
安裝加工部4包括：成形模具30，亦為頭部加工部3的一部分；未圖示的帶供給裝置，相對於成形模具30而於前方處將鏈帶8向上方向間歇地供給；以及一對側衝頭40、側衝頭40，相對於成形模具30而於上方處且在左右方向上隔開間隔配置，並且對於成形著嚙合凸部7c與嚙合凹部7d的鏈牙原材料7夾著其一對腳部7b、腳部7b而固定於鏈帶8。The mounting processing portion 4 includes a molding die 30 and a part of the head processing portion 3; a tape supply device (not shown) intermittently supplies the chain tape 8 in the upward direction with respect to the molding die 30; The side punch 40 and the side punch 40 are disposed at an upper position in the left-right direction with respect to the molding die 30, and sandwich the element 7 of the element forming the engaging convex portion 7c and the engaging concave portion 7d. The leg portion 7b and the leg portion 7b are fixed to the chain belt 8.

7)在頭部加工部3的6)的步驟，即成形衝頭32及壓力墊34上升的步驟的前後，沖柱20前進，而使切斷模具22與成形模具30前進，從而使成形模具30的前端部接近鏈帶8。當沖柱20到達限制前進的位置時，收容於成形模部31內的鏈牙原材料7的一對腳部7b、腳部7b配置於鏈帶8的左右兩側，一對側衝頭40、側衝頭40配置於一對腳部7b、腳部7b的左右外側。 7) In the step of 6) of the head processing unit 3, that is, before and after the step of raising the punch 32 and the pressure pad 34, the punch 20 advances, and the cutting die 22 and the forming die 30 are advanced to form the forming die. The front end portion of 30 is close to the chain belt 8. When the punch 20 reaches the position where the restriction is advanced, the pair of leg portions 7b and the leg portions 7b of the element material 7 housed in the molding die portion 31 are disposed on the right and left sides of the fastener tape 8, and the pair of side punches 40, The side punch 40 is disposed on the left and right outer sides of the pair of leg portions 7b and the leg portions 7b.
8)一對側衝頭40、側衝頭40將一對腳部7b、腳部7b以縮小其左右的間隔的方式進行壓入，從而於一對腳部7b、腳部7b之間夾持鏈帶8。 8) The pair of side punches 40 and the side punches 40 press the pair of leg portions 7b and the leg portions 7b so as to narrow the left and right intervals, thereby sandwiching between the pair of leg portions 7b and the leg portions 7b. Chain belt 8.
9)鏈帶8上升規定長度而停止。 9) The chain belt 8 is lifted by a predetermined length and stopped.
10)當沖柱20如7)般前進時，切斷衝頭24的刀面26離開鏈牙原材料7，當沖柱20到達限制前進處時，切斷衝頭24的刀面26的前方能夠被供給鏈牙用線材6。而且，未圖示的線材供給裝置將鏈牙用線材6以相當於一個鏈牙原材料的厚度供給至較切斷模具22的滑動接觸面22a靠上方處。據此，回到剪切加工部2中的1)的狀態。 10) When the punch 20 advances as in 7), the blade face 26 of the cut punch 24 is separated from the element material 7, and when the punch 20 reaches the limit advance position, the front face of the cutter face 26 of the punch 24 can be cut. The elemental wire 6 is supplied. Further, the wire supply device (not shown) supplies the element wire material 6 to the upper side of the sliding contact surface 22a of the cutting die 22 in a thickness corresponding to one element material. According to this, the state of 1) in the shearing processing unit 2 is returned.
11)藉由以後重複2)至10)，而將鏈牙原材料7安裝於鏈帶8。 11) The element material 7 is attached to the chain belt 8 by repeating 2) to 10) later.
