Abstract
The utility model discloses a puncher pin structure for bending plates. The utility model comprises a puncher pin body of which the width is larger than or equal to that of a bended plate. The utility model is characterized in that a lower corner on one side of the puncher pin body close to the plate is embedded with a punching stick which is horizontally arranged. The contact face of the punching stick and the puncher pin body is larger than the half circle of the stick body, and the punching stick is composed of a metallic stick core and an antiwear layer which is sheathed on the metallic stick. The surface strength of the antiwear layer is smaller than that of a bended plate. The utility model uses the different surface strengths of a working part and a processed part to change a punching wear surface into a working part, so the utility model ensures the integrity of the bended plate and avoids wear.
Description
Technical field
The utility model relates to the bending machining of metallic plate to be handled, and is specifically related to a kind of punch structure that adopts when utilizing the impact style bent plate.
Background technology
In the prior art,, can adopt the method for punching press, need to adopt diel in its device for crooked metal sheet.Usually, diel is inserted by the bending that is positioned at sheet material below and the drift of punching press under a side direction is inserted in bending constitutes, and the working portion of described drift comprises first plane of bottom, second plane of a side and connect first plane and the transition face on second plane; Shown in accompanying drawing 1, its course of work is generally, when bent plate, the press slide block passes to towards first power F1 down, in BENDING PROCESS, can resolve into normal pressure F3 and the power F2 that is parallel to plate surface perpendicular to plate surface, at the beginning, first plane contacts with sheet material, normal pressure F3 makes sheet material to lower stress, because the support that the bending of a side is inserted, sheet material bends, and the power F2 that is parallel to plate surface constantly aggravates the sheet bending degree, finally makes sheet bending to required form; In this process, normal pressure F3 can make drift working portion and plate surface produce violent sliding friction, and this sliding friction can make plate surface produce scratch, causes such as problems such as product surface bad order, electrodeposited coating damage, product get rusty.
Summary of the invention
The utility model purpose provides a kind of punch structure that is used for bent plate, by the improvement to punch structure, solves in punching course product surface by the abrasive problem of drift.
For achieving the above object, the technical solution adopted in the utility model is: a kind of punch structure that is used for bent plate, comprise that width is greater than more than or equal to the drift body that is bent sheet material, the inferior horn place of the nearly sheet material side of described drift body, be embedded with horizontally disposed punching press rod, the contact-making surface of described punching press rod and drift body is greater than the barred body half cycle, described punching press rod is made up of metal bar core and the wearing layer that is sheathed on the metal bar core, and the surface strength of described wearing layer is less than the surface strength that is bent sheet material.
During punching press, the press slide block passes to towards first power down, when drift moves downward, the outer surface lower end of punching press rod at first touches sheet material, compressing sheet material, and under the effect that the bending of bottom is inserted, make sheet bending, in BENDING PROCESS, the pressure of press slide block transmission can resolve into the normal pressure and the power that is parallel to plate surface perpendicular to plate surface, because the surface strength of the outside wearing layer of punching press rod is less than the surface strength that is bent sheet material, therefore, in normal pressure and be parallel under the power effect of plate surface, when producing sliding friction between drift working portion and the sheet material, what be worn is the less wearing layer of surface strength, thereby avoids being bent the wearing and tearing that sheet material causes.
The punching press rod is embedded in the depression on the drift body, because contact-making surface greater than the barred body half cycle, can not drop, more preferably scheme is, the punching press rod is 55% to 65% of barred body surface with the contact-making surface of drift body.
In the technique scheme, the two ends of described punching press rod are provided with limiting plate, and limiting plate is fixed on the drift body by screw.For preventing the left and right sidesing shifting of punching press rod when working,, that the punching press rod is fixing by being fixed in the limiting plate of drift body both sides.
In the technique scheme, described wearing layer is a nylon layer, and the thickness of wearing layer is between 0.8 millimeter-1.5 millimeters.Nylon is a kind of macromolecular material, has higher hardness and good wearability, and the position of bending is accurate when possessing certain rigidity and can guarantee punching press, and simultaneously, the hardness of nylon is lower than the sheet metal that is stamped, and can not make the plate surface wearing and tearing; The thickness of wearing layer is relevant with the effect of this programme, blocked uply can cause moderate finite deformation when punching press, influences bending precision; It is not enough to cross thin wearability, thereby makes wearing layer need regular replacing, and anti-wear effect is not good yet.
More preferential technical scheme is that the thickness of described nylon layer is 1 millimeter.
Because the technique scheme utilization, the advantage that the utility model compared with prior art has is:
Because the utility model is embedded with the punching press rod at the working portion of drift body, the punching press rod by the metal bar core and be sheathed on its outside, surface strength forms less than the wearing layer of the surface strength that is bent sheet material, when producing sliding friction in the punching course, what wear and tear will be the wearing layer of the less punching press rod of surface strength, thereby avoided the galled spots that in the punching course sheet material is caused, improved the quality of products.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment one: referring to accompanying drawing 2 to shown in the accompanying drawing 8, a kind of punch structure that is used for bent plate, comprise that width is more than or equal to the drift body 1 that is bent sheet material, the inferior horn place of described drift body 1 nearly sheet material side, be embedded with horizontally disposed punching press rod 2,60% of the contact-making surface barred body surface of described punching press rod 2 and drift body 1, described punching press rod 2 is made up of metal bar core 3 and the wearing layer 4 that is sheathed on the metal bar core 3, described wearing layer 4 is the nylon layer of surface strength less than the surface strength that is bent sheet material 5, and its thickness is 1 millimeter.The two ends of described punching press rod 2 are provided with limiting plate 6, and limiting plate 6 is fixed on the drift body 1 by screw 7, with the left and right sidesing shifting that prevents that the punching press rod from producing when working.
In the present embodiment, the lateral surface of described punching press rod 2 (promptly being exposed to the surface in the drift body outside) is the working portion of drift, when punching press, the press slide block passes to towards first power down, when drift moves downward, the working portion contact sheet material 5 of punching press rod 2, and compressing sheet material 5, under the effect that the bending of bottom is inserted, make sheet material 5 bendings, in BENDING PROCESS, the pressure of press slide block transmission can resolve into the normal pressure and the power that is parallel to sheet material 5 surfaces perpendicular to sheet material 5 surfaces, because the surface strength of the nylon layer on the punching press rod 2 is less than the intensity on the surface that is bent sheet material, therefore, the force of sliding friction that punching press produced, the nylon layer that wear surface intensity is less, processed sheet material is injury-free.
