在一些实施例中，所述底角的角度为45-85度。In some embodiments, the base angle ranges from 45 to 85 degrees.
上述实施方式中，将梯形远离开口的角度设置为45-85度时，一方面有利于铆接工业流程化，一方面有利于提高铆接件的铆接质量。具体 地，当底角小于45度时，由于不同铆接件的延展性不同，铆接件材料挤压进底角后可能会出现底角填充不充分，不利于铆接工业流程化。当底角大于85度时，铆接件互锁值较小，铆接质量不理想。In the above embodiment, when the angle of the trapezoid away from the opening is set to 45-85 degrees, on the one hand, it is conducive to streamlining the riveting industry, and on the other hand, it is conducive to improving the riveting quality of the riveted parts. Specifically, when the bottom angle is less than 45 degrees, due to the different ductility of different riveting parts, insufficient filling of the bottom corner may occur after the material of the riveting part is extruded into the bottom corner, which is not conducive to the process flow of the riveting industry. When the bottom angle is greater than 85 degrees, the interlocking value of the riveted parts is small and the riveting quality is not ideal.

The anti-rust coating or paint layer of the riveted parts will deform and flow along with the riveted parts, which will not cause damage to the surface of the riveted parts and will not cause damage to the surface of the riveted parts. It will affect the corrosion resistance and strength of the riveted parts at the connection points.

应理解，铆接过程中利用铆接头将铆接件压入凹台时，铆接头的宽度会受腔体开口宽度的限制，因此在铆接头的底端设置凸出部，利用凸出部将铆接件压入凹台内。通过在铆接头底部设置凸出部，可以根据腔体开口的宽度，灵活地设置凸出部的大小。It should be understood that when the riveting head is used to press the riveted part into the concave platform during the riveting process, the width of the riveting head will be limited by the width of the cavity opening. Therefore, a protrusion is provided at the bottom of the riveting head, and the protrusion is used to push the riveted part into the recess. Press into the concave platform. By providing a protrusion at the bottom of the rivet head, the size of the protrusion can be flexibly set according to the width of the cavity opening.
在一些实施例中，所述凸出部深度方向的截面为梯形，远离所述铆接头的底角为钝角。In some embodiments, the cross-section in the depth direction of the protrusion is trapezoidal, and the base angle away from the rivet head is an obtuse angle.
上述实施方式，将梯形的底角设置为钝角，相较于将底角设置为直角或锐角，铆接件的上层板材在铆接后的剩余材料更多，即剩余材料厚度值更大，有利于提高铆接质量。In the above embodiment, the bottom angle of the trapezoid is set to an obtuse angle. Compared with setting the bottom angle to a right angle or an acute angle, the upper plate of the riveted part has more remaining material after riveting, that is, the thickness of the remaining material is larger, which is beneficial to improving the Riveting quality.
在一些实施例中，所述凸出部深度方向的截面为等腰梯形。In some embodiments, the cross-section in the depth direction of the protrusion is an isosceles trapezoid.
上述实施方式，当凸出部深度方向的截面为等腰梯形时可以使得铆接件完成铆接后，各处铆接厚度相同，有利于提高铆接扣的连接强度，提高铆接质量。According to the above embodiment, when the cross-section in the depth direction of the protrusion is an isosceles trapezoid, the riveting thickness can be the same everywhere after the riveting is completed, which is beneficial to improving the connection strength of the riveting buckle and improving the riveting quality.
在一些实施例中，所述凸出部的最大径向尺寸小于所述开口的宽 度。In some embodiments, the maximum radial dimension of the protrusion is less than the width of the opening.
应理解，为了利用铆接头的凸出部将铆接件压入凹台，凸出部的最大径向尺寸小于开口的宽度。It should be understood that in order to use the protrusion of the rivet head to press the rivet into the recess, the maximum radial dimension of the protrusion is smaller than the width of the opening.
本申请的技术方案，通过将铆模设置为两个或两个以上可分离的结构，配合转轴和/或滑轨使铆接件在完成铆接后快速顺利脱模。进一步地，将铆模的腔体设置为正梯形结构，可以增大铆接后的铆接件的上下板材间互锁值，将铆接头的凸出部设置为倒梯形结构，可以增加剩余材料厚度，从而提高铆接件的铆接质量。The technical solution of this application is to configure the riveting mold into two or more separable structures, and cooperate with the rotating shaft and/or the slide rail to enable the riveted parts to be quickly and smoothly demoulded after the riveting is completed. Furthermore, setting the cavity of the riveting mold as a straight trapezoidal structure can increase the interlocking value between the upper and lower plates of the riveted part after riveting, and setting the protruding part of the riveting head as an inverted trapezoidal structure can increase the thickness of the remaining material. Thereby improving the riveting quality of riveted parts.

为了降低车身重量，实现减重效能，节能减排，汽车车身将逐步采用铝合金、镁合金和复合材料等新轻型板材代替钢板。然而，传统的材料连接技术，如电焊，激光焊等，由于成本过高，焊接性差等因素，很难实现新轻型板材的连接。自冲铆接作为一种板材新型冷加工连接技术，利用板材的塑性大变形形成机械内锁达到连接板料的目的。根据有无铆钉，自冲铆可以分为有铆自冲铆接和无铆钉自冲铆接两种形式。其中，有铆自冲铆接是通过压头将铆钉刺穿上层板材和下层板材或刺穿上层板材但不刺穿下层板材，然后在冲头和铆模的共同作用下铆钉向周边翻开形成铆扣，使上下板材形成一个机械内锁结构；无铆钉自冲(clinching)铆接利用铆接头配合铆模，通过冲压力使上下连接板材形成机械互锁。铆接完成后，互锁值和材料剩余厚度是衡量铆接质量的重要指标。以clinching铆接为例， 图1是clinching铆接接头的示意图，其中铆接件中上层板111和下层板222铆接后形成铆接接头，m为铆接的互锁值。n为铆接后的材料剩余厚度。In order to reduce the weight of the car body, achieve weight reduction efficiency, save energy and reduce emissions, the automobile body will gradually use new lightweight plates such as aluminum alloys, magnesium alloys and composite materials to replace steel plates. However, traditional material connection technologies, such as electric welding and laser welding, are difficult to connect new lightweight plates due to factors such as high cost and poor weldability. Self-piercing riveting is a new cold processing connection technology for plates, which uses the large plastic deformation of the plates to form mechanical internal locks to connect the plates. According to the presence or absence of rivets, self-piercing riveting can be divided into two forms: self-piercing riveting with rivets and self-piercing riveting without rivets. Among them, self-piercing riveting uses a pressure head to pierce the upper plate and the lower plate or the upper plate but not the lower plate, and then the rivets are opened to the periphery under the combined action of the punch and the riveting die to form a rivet. Buckle, so that the upper and lower plates form a mechanical internal locking structure; rivet-less self-piercing (clinching) riveting uses a rivet head to cooperate with a riveting die, and the upper and lower connected plates form a mechanical interlock through punching force. After riveting is completed, the interlocking value and the remaining thickness of the material are important indicators for measuring the quality of the riveting. Taking clinching riveting as an example, Figure 1 is a schematic diagram of a clinching riveting joint, in which the upper plate 111 and the lower plate 222 in the riveted part are riveted to form a riveted joint, and m is the interlocking value of the riveting. n is the remaining thickness of the material after riveting.
为了便于铆接件完成铆接后顺利脱模，目前大部分铆模的腔体设为圆柱形或倒圆台形，但这种腔体会导致铆接后互锁值偏小，且材料剩余厚度不足，进而导致铆接件在使用过程中容易出现断裂或者脱扣的现象。In order to facilitate the smooth demoulding of the riveted parts after riveting, the cavities of most riveting molds are currently set to a cylindrical or truncated cone shape. However, such cavities will lead to a small interlocking value after riveting and insufficient remaining thickness of the material, resulting in Riveted parts are prone to breakage or disconnection during use.
鉴于此，本申请提出了一种可分离式铆模，有利于铆接件完成铆接后顺利脱模。In view of this, this application proposes a detachable riveting mold, which is beneficial to the smooth demoulding of the riveted parts after the riveting is completed.

本申请中，铆接件30可以包括至少一层上层板31和至少一层下层板32。In this application, the rivet 30 may include at least one upper layer plate 31 and at least one lower layer plate 32 .
需要说明的是，当第一部件11和第二部件12围合成闭合状态时进行铆接件30的铆接工作。图2仅示出了铆模10被设计成两个分体结构，即第一部件11和第二部件12，虽未示出，本申请提供的铆模10还可以包括三个或三个以上的分体结构，所有分体结构围合形成凹台1，且在铆接完成后分离从而使得铆接件30顺利从铆模10中脱离即可。It should be noted that the riveting work of the riveting member 30 is performed when the first component 11 and the second component 12 are enclosed in a closed state. Figure 2 only shows that the riveting mold 10 is designed into two separate structures, namely the first component 11 and the second component 12. Although not shown, the riveting mold 10 provided by the present application can also include three or more All the split structures are enclosed to form a concave platform 1, and separated after the riveting is completed, so that the riveting part 30 can be smoothly separated from the riveting mold 10.
凹台1的上表面可以为平面，用于放置铆接件30。凹台1的侧面可以为平面也可以为弧形面，本申请对此不作限定。腔体13一端具有开口，可以理解为从凹台1的上表面中心处设置了一个凹槽，该凹槽可以为任意一种几何体，例如长方体、圆柱体，圆台等，本申请对此不作限定。The upper surface of the concave platform 1 may be a flat surface for placing the rivet 30 . The side surface of the concave platform 1 may be a flat surface or an arc surface, which is not limited in this application. The cavity 13 has an opening at one end, which can be understood as a groove provided from the center of the upper surface of the recess 1. The groove can be any geometric shape, such as a rectangular parallelepiped, a cylinder, a truncated cone, etc., which is not limited in this application. .
第一部件11和第二部件12可分离可以指第一部件和11和第二部件12完全分离，也可以指第一部件11和第二部件12的一部分相互分离，例 如，第一部件11和第二部件12可以以张开的状态分离，即顶部张开，底部仍然接触。第一部件11和第二部件22可以通过主动和被动两种方式分离。其中主动分离例如可以是铆接完成后，利用其他部件驱使第一部件11和第二部件12自动相互分离；被动分离例如可以是铆接完成后，铆接件向上回程，将第一部件11和第二部件12顶开。The separability of the first component 11 and the second component 12 may mean that the first component 11 and the second component 12 are completely separated, or it may mean that a part of the first component 11 and the second component 12 is separable from each other. For example, the first component 11 and the second component 12 are separable. The second part 12 can be separated in an open state, ie the top part is open and the bottom part remains in contact. The first part 11 and the second part 22 can be separated in two ways: active and passive. Active separation can be, for example, using other components to drive the first component 11 and the second component 12 to automatically separate from each other after riveting is completed; passive separation can be, for example, after riveting is completed, the riveting part returns upward to separate the first component 11 and the second component. 12 top open.

在一些实施例中，铆模10还包括驱动机构2，驱动机构2用于驱动第一部件11和第二部件12相互分离或靠近。In some embodiments, the riveting mold 10 further includes a driving mechanism 2, which is used to drive the first component 11 and the second component 12 to separate or approach each other.
应理解，当铆接件30进行铆接时，驱动机构2驱使第一部件11和第二部件12相互靠近，形成闭合的铆模10结构，以保证铆接工作的正常进行。当铆接件30完成铆接后，驱动机构2驱使第一部件11和第二部件12相互分离，以保证完成铆接的铆接件30顺利快速从铆模10中脱离；铆接件30完成铆接后，驱动机构2再驱使第一部件11和第二部件12相互靠近，以此保证铆模10实现连续自动化铆接。It should be understood that when the riveting component 30 is riveted, the driving mechanism 2 drives the first component 11 and the second component 12 to approach each other to form a closed riveting mold 10 structure to ensure normal riveting work. When the riveting part 30 is riveted, the driving mechanism 2 drives the first part 11 and the second part 12 to separate from each other to ensure that the riveting part 30 is smoothly and quickly detached from the riveting mold 10; after the riveting part 30 is riveted, the driving mechanism 2.

For example, the fixing member 5 can be a plate-shaped structure, a columnar structure, etc.
应理解，若支撑件3不设置固定件5时，驱动机构2与第一部件11或第二部件12的连接处存在夹角，当夹角角度较小时，需要较大的驱动力才能将第一部件11与第二部件12分离，因此，当支撑件3包括向凹台1突出的固定件5，并将驱动机构2的一端连接于固定件5时，可以有效增大驱动机构2与凹台1的夹角角度，从而降低所需驱动力使第一部件11与第二部件12相互分离。It should be understood that if the support member 3 is not provided with the fixing member 5, there will be an included angle at the connection between the driving mechanism 2 and the first component 11 or the second component 12. When the included angle is small, a larger driving force will be required to move the second component. One part 11 is separated from the second part 12. Therefore, when the support member 3 includes a fixing part 5 protruding toward the concave platform 1, and one end of the driving mechanism 2 is connected to the fixing part 5, the connection between the driving mechanism 2 and the concave platform can be effectively increased. The included angle of the stage 1 is reduced, thereby reducing the required driving force to separate the first component 11 and the second component 12 from each other.

梯形远离开口的底角可以理解为腔体13的侧面与底面的夹角。梯形远离开口的底角为锐角，即角A和角B为锐角。其中，角A可以和角B的角度值相等，也可以不相等。当角A和角B为锐角时，腔体13深度方向的截面为上底边a长度小于下底边b长度的梯形。The bottom angle of the trapezoid away from the opening can be understood as the angle between the side surface and the bottom surface of the cavity 13 . The base angle of the trapezoid away from the opening is an acute angle, that is, angle A and angle B are acute angles. Among them, the angle value of angle A and angle B may or may not be equal. When angle A and angle B are acute angles, the cross-section in the depth direction of the cavity 13 is a trapezoid with the length of the upper base a smaller than the length of the lower base b.
应理解，图2仅示出了铆模10的某一截面，只能示出该截面下两个底角的角度，实体结构中，腔体13的侧面与底面的夹角可以有多个，这些夹角的角度可以相同也可以不同，本申请对此不作限定。It should be understood that Figure 2 only shows a certain cross-section of the riveting mold 10, and can only show the angles of the two bottom corners of the cross-section. In the physical structure, there can be multiple angles between the side and the bottom surface of the cavity 13. The angles of these included angles may be the same or different, and are not limited in this application.
示例性的，腔体13深度方向的截面为梯形时，该腔体13可以为四棱台，也可以为圆台，即腔体13的基底面为四边形，也可以为圆形或其它几何体形状。For example, when the cross-section in the depth direction of the cavity 13 is a trapezoid, the cavity 13 can be a quadrangular pyramid or a circular cone, that is, the base surface of the cavity 13 can be a quadrilateral, a circle, or other geometric shapes.
通过设置深度方向截面为梯形的腔体13结构可以在铆接时，使铆接件30的更多材料被挤压进底角，进而增大铆接件30中上层板31与下层板32的互锁值，从而提高铆接质量。By arranging the cavity 13 structure with a trapezoidal cross-section in the depth direction, more material of the riveting part 30 can be squeezed into the bottom corner during riveting, thereby increasing the interlocking value of the upper plate 31 and the lower plate 32 in the riveting part 30 , thereby improving the riveting quality.
需要说明的是，本申请实施例中，腔体13的结构除了被设置为 梯形外，还可以根据实际需求设计为与梯形类似的结构，例如，为了使得铆接后形成的铆接扣更为光滑，不易划伤人和其他零部件，可以将梯形的上底角和/或下底角设置为圆角。It should be noted that in the embodiment of the present application, in addition to being configured as a trapezoid, the structure of the cavity 13 can also be designed as a structure similar to a trapezoid according to actual needs.

可选地，在本申请的一些实施例中，如图2所示，梯形为等腰梯形。Optionally, in some embodiments of the present application, as shown in Figure 2, the trapezoid is an isosceles trapezoid.
参考图2，梯形为等腰梯形即角A与角B相等，但应理解，在实际腔体13结构中，梯形为等腰梯形是指腔体13的侧面与底面的夹角角度各处相等。Referring to Figure 2, the trapezoid is an isosceles trapezoid, that is, angle A and angle B are equal. However, it should be understood that in the actual structure of the cavity 13, the trapezoid is an isosceles trapezoid, which means that the angles between the side and the bottom of the cavity 13 are equal everywhere. .
当腔体13深度方向的截面为等腰梯形时，挤压进底角的铆接件30的材料量相等，则铆接件各处的互锁值相同，可以使铆接完成后形成的铆接扣各处质量均匀，进一步提高铆接质量。When the cross-section in the depth direction of the cavity 13 is an isosceles trapezoid, the amount of material of the riveted parts 30 extruded into the bottom corners is equal, and the interlocking values of the riveted parts are the same everywhere, so that the riveted buckle formed after riveting is completed can be made everywhere The quality is uniform, further improving the riveting quality.
可选地，在本申请实施例中，底角的角度为45-85度。即角A和/或角B的角度为45-85度。Optionally, in the embodiment of the present application, the angle of the bottom angle is 45-85 degrees. That is, the angle of angle A and/or angle B is 45-85 degrees.
本申请实施例将底角设置为45-85度，一方面有利于铆接工业流程化，一方面有利于提高铆接件30的铆接质量。当底角小于45度时，由于不同铆接件30的延展性不同，材料挤压进底角后可能会出现底角填充不充分，不利于铆接工业流程化。当底角大于85度时，铆接件30互锁值较小，铆接质量不理想。In the embodiment of the present application, the bottom angle is set to 45-85 degrees, which is conducive to streamlining the riveting industry on the one hand, and is conducive to improving the riveting quality of the riveting part 30 on the other hand. When the bottom angle is less than 45 degrees, due to the different ductility of different riveting parts 30, insufficient filling of the bottom corner may occur after the material is extruded into the bottom corner, which is not conducive to the process flow of the riveting industry. When the bottom angle is greater than 85 degrees, the interlocking value of the riveting parts 30 is small, and the riveting quality is not ideal.

As the pressure of the riveting head 7 increases, the material deforms in the cavity 13, and the upper layer The plate 21 and the lower plate 22 form an inlaid structure, that is, a riveted buckle, and the pressure of the riveted joint 7 relaxes and returns.
铆接过程中通过铆接头7的压力将铆接件30压入铆模10，铆接件30的防锈镀层或漆层会随着铆接件30一起变形流动，不会对铆接件30的表面造成破坏，也不会影响铆接件30连接点处的抗腐蚀性及强度。During the riveting process, the riveting part 30 is pressed into the riveting mold 10 by the pressure of the riveting head 7. The anti-rust coating or paint layer of the riveting part 30 will deform and flow together with the riveting part 30, and will not cause damage to the surface of the riveting part 30. It will not affect the corrosion resistance and strength of the connection points of the rivets 30.
