Abstract
The utility model discloses a punching head structure used for bending plate. The utility model comprises a punching head body of which the width is larger than that of a plate to be bended. The utility model is characterized in that a roll shaft is arranged on the lateral lower part of the punching head body, both ends of the roll shaft are connected with the punching head body through bearings, and the surface of the outer side of the roll shaft forms a working surface of the punching head structure. When the utility model is used for punching the plate, the utility model replaces a sliding method with a rolling method to prevent the surface of a product from being abraded by the punching head.
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 the drift body for the treatment of the twisted plate material, the side lower part of described drift body is provided with roller bearing, described roller bearing two ends are connected with the drift body by bearing, and the outer surface of roller bearing constitutes the working surface of punch structure.
During punching press, the press slide block passes to towards first power down, when drift moves downward, the outer surface lower end of roller bearing 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 roller bearing is connected with the drift body with bearing, the power that is parallel to plate surface is rotated roller bearing, under bigger positive pressure, do not produce slippage between roller surface and sheet material, thereby can not wear and tear plate surface, in the whole process, roller bearing produces normal pressure with the moving mutually rolling of sheet material and to it, make sheet bending, the drift body does not contact with sheet material.
In the technique scheme, the syndeton of described roller bearing and drift body is, the two ends of drift body extend laterally and constitute the bearing fixing position, and bearing fixing has dead eye on the position, bearing outer ring is fixed in the dead eye, fixedlys connected with bearing inner race in described roller bearing two ends.
Wherein, described drift body is provided with the depression with the roller bearing form fit.
Further technical scheme also is provided with a pair of fixed head, and described fixed head is located at roller bearing and bearing two ends, and fixedlys connected with the drift body.
Another kind of technical scheme is, the syndeton of described roller bearing and drift body is, is provided with a pair of connecting plate, and described connecting plate is fixedlyed connected with the drift body, connecting plate is provided with the dead eye bearing outer ring and is fixed in the dead eye, fixedlys connected with bearing inner race in described roller bearing two ends.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1. because the utility model is provided with roller bearing, and when pressing sheet material, roller bearing contacts with sheet material, has substituted slip with rolling, thereby avoided product surface to be abraded by drift.
2. be connected by bearing between roller bearing and drift body, and fix with fixed head, thereby guaranteed slippage can not take place between roller bearing and sheet material, the power that the drift body is subjected to can be passed to sheet material through roller bearing effectively, with the sheet material bending.
