Abstract
A shearing bending die structure comprises an upper die and a lower die, wherein the upper die comprises an upper die base, an upper backing plate, an upper clamping plate, a stripping plate and a stripping plate which are sequentially arranged from top to bottom; one edge and the other edge of the punch are respectively provided with a bending functional surface matched with the bending block and a shearing functional surface matched with the lower die edge; the distance between the material shearing functional surface and the upper backing plate is larger than the distance between the bending functional surface and the upper backing plate. The beneficial effects of the utility model are that owing to adopt foretell structural design, can cut the material and bend two processing technology in a work station, can also reduce the angle resilience of bending.
Description
Technical Field
The utility model belongs to the technical field of stamping die technique and specifically relates to a cut material mould structure of bending.
Background
The former progressive die needs to respectively carry out two processing technologies of material shearing and bending, and has the problems of complex working procedures, large bending angle resilience of products and the like.
Thus, the prior art is subject to improvements and improvements.
Disclosure of Invention
To the weak point that exists among the prior art, the utility model aims at providing a simple, the reduction product angle rebound volume of bending cut material mould structure of bending.
In order to achieve the above object, the utility model adopts the following technical scheme:
a shearing bending die structure comprises an upper die and a lower die, wherein the upper die comprises an upper die base, an upper backing plate, an upper clamping plate, a stripping plate and a stripping plate which are sequentially arranged from top to bottom; one edge and the other edge of the punch are respectively provided with a bending functional surface matched with the bending block and a shearing functional surface matched with the lower die edge; the distance between the material shearing functional surface and the upper backing plate is greater than the distance between the bending functional surface and the upper backing plate; and an ejector rod is movably arranged in the bending block in a penetrating manner, and the bottom of the ejector rod is connected with a spring arranged on the lower die base.
Preferably, the inner wall surface of the lower die cutting edge matched with the punch is an inclined surface.
Preferably, the inclination angle of the inclined surface is 1.5 degrees.
Compared with the prior art, the beneficial effects of the utility model are that:
due to the adoption of the structural design, two processing technologies of material shearing and bending can be carried out in one work station, and the bending angle rebound can be reduced.
Drawings
FIG. 1 is a schematic structural view of the mold opening state of the present invention;
fig. 2 is a schematic structural diagram of the mold closing state of the present invention.
The reference numbers in the figures are respectively: (1) the stamping die comprises an upper die base, (2) an upper backing plate, (3) an upper clamping plate, (4) a backing plate removing, (5) a material removing plate, (6) a lower die plate, (7) a lower backing plate, (8) a lower die base, (10) a punch, (11) a bending block, (12) a lower die knife edge, (13) a bending functional surface, (14) a material shearing functional surface, (15) an ejector rod, (16) a spring and (17) an inclined surface.
Detailed Description
The invention will be described in further detail with reference to the accompanying drawings:
referring to fig. 1, the utility model relates to a material shearing and bending die structure, which comprises an upper die and a lower die, wherein the upper die comprises an upper die base 1, an upper padding plate 2, an upper clamping plate 3, a stripping plate 4 and a stripping plate 5 which are sequentially arranged from top to bottom, the lower die comprises a lower die plate 6, a lower padding plate 7 and a lower die base 8 which are sequentially arranged from top to bottom, a spring is arranged between the upper padding plate and the stripping plate, a punch 10 is fixed on the upper padding plate 2, and the punch 10 is matched with a bending block 11 arranged on the lower die plate 6 and a lower die knife edge 12 after passing through the upper clamping plate 3, the stripping plate 4 and the stripping plate 5; one edge and the other edge of the punch are respectively provided with a bending functional surface 13 matched with the bending block 11 and a shearing functional surface 14 matched with the lower die blade 12; the distance between the material shearing functional surface 14 and the upper backing plate is greater than the distance between the bending functional surface 13 and the upper backing plate, so that the bending is ensured by shearing materials firstly; an ejector rod 15 is movably arranged in the bending block in a penetrating mode, and the bottom of the ejector rod 15 is connected with a spring 16 arranged on the lower die base 9.
The inner wall surface of the lower die cutting edge 12 matched with the punch 10 is an inclined surface, and the inclined angle of the inclined surface is 1.5 degrees, so that the contact surface between the punch and the lower die cutting edge 12 can be reduced, and friction is reduced.
When the utility model works, please refer to fig. 1 and fig. 1, a product to be processed is firstly placed on the lower template 6, the upper die moves downwards, the stripper plate 5 firstly contacts the product to be processed, the upper die moves downwards continuously, the material shearing functional surface 14 of the punch contacts with the lower die knife edge 12 and shears the product to be processed; the upper die continues to move downwards, the bending functional surface 13 of the punch bends and forms a product to be processed, and then the material shearing and bending operation is completed; and the upper die moves upwards, and the ejector rod 15 extends out of the bending block 11 and jacks up a product to be processed under the action of the spring 16 by the ejector rod 15, so that the material is removed.
To sum up, the utility model discloses an foretell structural design solves the weak point that exists among the prior art, has characteristics such as rational in infrastructure, process are simple.
The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
