Abstract

The utility model relates to a punch, which mainly improves the combination mode of the upper and the lower moulds of patterns for a conventional punch. A cylinder-shaped projection which is arranged on an upper mould seat is matched with a cylinder-shaped guided mould hole which is arranged on a lower mould seat so that the upper and the low moulds can reach the effect of contraposition. The utility model overcomes the problem that the projection of the upper mould seat and the guided mode hole of the lower mould seat must be matched with the patterns to perform a complex match. Not only the utility model enable the upper and the lower mould of the puch to assemble easily, but also the phenomenon of uncertainty for operation and jamming because of Abrasion or deformation can be avoided. Thus, the utility model has the advantages of long service life for the punch, low manufacture cost, and better industry utility for the punch.

Description

Puncher

The utility model relates to a kind ofly can get the puncher with various pattern emptying aperture on the stationery article, relate in particular to the improvement of the structure of inner nib of puncher and die holder.

Press, the puncher structure of commonly using as shown in Figure 1, its main composition is that a case 1 ＇ contains one by press button 2 ＇, upper bolster 3 ＇, compression spring 4 ＇ and die shoe 5 ＇, wherein case 1 ＇ is provided with a hole, can make by press button 2 ＇ in the combination processus aboralis for outside, by press button 2 ＇ be closing in upper bolster 3 ＇, and upper bolster 3 ＇ are provided with prominent body 31 ＇ of a pattern form, guided mode hole 51 ＇s set with die shoe 5 ＇ cooperate, and then are equipped with a compression spring 4 ＇ between upper bolster 3 ＇ and die shoe 5 ＇; During use, paper or card are placed the paper feed port of die shoe 5 ＇ bottom sides, press by press button 2 ＇ with finger, just can oppress upper bolster 3 ＇ and die shoe 5 ＇ closings, utilize the shear action of the body 31 ＇ pattern hole corresponding of dashing forward of upper bolster 3 ＇ with die shoe 5 ＇, can be at the emptying aperture of getting a specific pattern on the paper or on the card, when finger is decontroled, upper bolster 3 ＇ and die shoe 5 ＇ then playback because of the effect of compression spring 4 ＇, some problems often appear in right its on making or on using, prominent body 31 ＇ that go up as upper bolster 3 ＇ and guided mode hole 51 ＇ of die shoe 5 ＇ all are to be benchmark with designed pattern, must be quite accurate on cooperating, if pattern is complicated slightly or to being referred to as under the situation, certainly will cause the puzzlement in the assembling, and the crack is quite little after between prominent body 31 ＇ and guided mode hole 51 ＇, if on making or using, when a side has the phenomenon of formation abrasion to take place, well imagine ground, to produce action not really even the situation of clamping stagnation is arranged, therefore form bad product easily and increase cost on foot.

Therefore, the purpose of this utility model is to provide a kind of puncher of improvement, and it can be eliminated and commonly use puncher assembling and be difficult for, and needs accurate contraposition and not anti abrasive shortcoming.

According to puncher of the present utility model, its composition includes a case, by press button, and can get the upper and lower mould of pattern of pattern emptying aperture on stationery or card, and is provided with a compression spring so that upper and lower mould resets at upper and lower intermode; It is characterized in that, upper bolster is provided with a cylindrical prominent body and the one side is cut into a plane, consubstantiality extends the prominent body of a pattern under it, die holder then is provided with the cylindrical guided mode hole that a side is cut into the plane relatively, the bottom side offers a pattern hole, utilize the cylindrical guided mode hole of the cylindrical prominent body of upper bolster and die shoe to cut the plane of establishing and can make the accurate contraposition of upper and lower die holder, and the die shoe body is provided with a room space with respect to Fang Ze under the guided mode hole, can be for temporarily storing the punching paper scrap.

Puncher of the present utility model has improved commonly uses difficult, the time-consuming shortcoming of puncher assembling, and has improved the tolerance of puncher upper and lower mould for wearing and tearing and distortion, has reduced manufacturing cost indirectly, has improved service life.

Describe structure, characteristics and the advantage of the utility model puncher in detail below in conjunction with accompanying drawing.

In the accompanying drawing:

Fig. 1 is for commonly using the three-dimensional exploded view of puncher structure.

Fig. 2 is the three-dimensional exploded view of the puncher of the utility model improvement.

Fig. 3 is the utility model combination rear side view and part cutaway view.

Fig. 4 is the stereogram of the utility model puncher.

Please consult simultaneously shown in Fig. 2,3, puncher of the present utility model system is designed to two partly with the prominent body 31 of upper bolster 3, and the first half constitutes with the simple circle cylindricality, is cut into a plane on one side, and Lower Half then cooperates designed pattern and forms the pattern body 32 of dashing forward; Relatively, 51 in the guided mode hole of die shoe 5 cooperates prominent body 31 shapes, and becomes the cylindrical emptying aperture that a side is the plane, and the bottom of die shoe 5 then cooperates the prominent body 32 of pattern to offer a pattern hole 52; Because guiding upper bolster 3 is to be made of simple cylindrical institute with the prominent body 31 and the guided mode hole 51 of die shoe 5 contrapositions, and a side respectively is cut into a plane, in assembling, as long as prominent body 31 is relative with the plane in guided mode hole 51, can be easily with upper bolster 3 and die shoe 5 combinations, relatively commonly use the practice of puncher, its prominent body 31 and guided mode hole 51 must cooperate the mode of pattern appearance contraposition to assemble, on packaging efficiency, the utility model is incomparable by commonly using puncher, and is especially more obvious under the situation of designed pattern complexity; Moreover, can mainly be 52 of pattern hole that occur in the prominent body 32 of pattern of upper bolster 3 and die shoe 5 in the shear action of getting the pattern emptying aperture on the paper or on the card, therefore, the sufficient length that the prominent body 32 of pattern only must possess the shear action of finishing gets final product, and needn't be as commonly using the prominent body 31 of puncher, guided mode hole 51 all must cooperate pattern form with pattern hole and combine, and so combination of complicated shape, the precision of its cooperation certainly will improve, tolerance for a little distortion or wearing and tearing reduces naturally, easily cause the uncertain or catching phenomenon of action, the probability increase that forms bad product is a corollary, so increase many costs virtually on making.Puncher of the present utility model is then eliminated the generation of this kind problem fully, the cylindrical compound mode in its prominent body 31 and guided mode hole 51, it is much higher to commonly use puncher for the permission of error, its manufacturing is quite easy, required precision does not need too high, and the prominent body 32 of pattern that pattern is sheared part does not directly contact with guided mode hole 51, and the chance of wearing and tearing greatly reduces; Moreover; the utility model still another characteristics of tool is the body of die shoe 5 and is provided with a room 53 with respect to 51 belows, guided mode hole; when drilling operation; paper scrap is promptly directly fallen into through guided mode hole 51 in this room 53 and to be suspended or storE; no anxiety can drop out in 5 external and unrestrained full chambers of die holder easily or tidy up difficulty, and this point is not also for comparatively commonly using the even better part of person.

In sum, puncher of the present utility model has improved commonly uses difficult, the time-consuming shortcoming of puncher assembling, and improved the tolerance of puncher upper and lower mould for wearing and tearing and distortion, reduced manufacturing cost indirectly, and the service life of prolongation puncher, so the utility model is not only creative and novelty, have more the practicality of height, the prominent application condition that meets utility model patent is so apply for utility model patent in accordance with the law.
