Abstract
The utility model discloses a kind of metal plate punching mould of replaceable drift, including：Punch-pin, drift and cavity plate, the punch-pin is correspondingly arranged up and down with cavity plate, mounting hole is offered on the lower surface of the punch-pin, the inwall of the mounting hole is provided with female thread structure, the drift includes upper end cylinder installation portion and the lower end pressing part being fixed together with the upper end cylinder installation portion, the upper end cylinder installation portion is removable to be arranged in the mounting hole, and the external thread structure to be cooperated with the female thread structure is integrally machined on the periphery wall of the upper end cylinder installation portion.By the above-mentioned means, the utility model, simple in construction, the stamping press to metal plate can be buffered, avoids fracture of the metal plate in punching course, while drift can be replaced according to different punching press shapes, use cost is low.
Description
Technical field
Technical field of mold is the utility model is related to, more particularly to a kind of metal plate punching mould of replaceable drift.
Background technology
The important component of metal plate punching mould includes punch-pin, cavity plate and drift, and general punch-pin is fixed one with drift
Formula structure, during punching press, metal plate is placed on cavity plate upper surface first, drives drift to carry out punching press to metal plate using punch-pin, and
By cavity plate punch forming, mold structure is simple, but is found in long-term use, and its shortcoming is easily caused in punching course
Metal plate is broken, and especially to slim metal plate punching, its product qualified rate is low, and this outer ram is structure as a whole with punch-pin, works as punching press
, it is necessary to change punch-pin and drift during hole slot of different shapes, use cost is big.
Utility model content
The utility model can avoid mainly solving the technical problems that a kind of metal plate punching mould of replaceable drift of offer
Metal plate is broken in punching course, while can change drift according to punching press shape, and use cost is low.
In order to solve the above technical problems, the technical scheme that the utility model uses is：A kind of replaceable drift is provided
Metal plate punching mould, including：Punch-pin, drift and cavity plate, the punch-pin are correspondingly arranged up and down with cavity plate, the lower end of the punch-pin
Mounting hole is offered on face, the inwall of the mounting hole is provided with female thread structure, and the drift includes upper end cylinder installation
Portion and the lower end pressing part being fixed together with the upper end cylinder installation portion, the upper end cylinder installation portion are removable
Formula is arranged in the mounting hole, and has been integrally machined and the internal thread knot on the periphery wall of the upper end cylinder installation portion
The external thread structure that structure cooperates.
In one preferred embodiment of the utility model, angle that the both sides side of the lower end pressing part connects with lower surface
For fillet.
In one preferred embodiment of the utility model, the angle that two medial surfaces of the cavity plate connect with upper surface is circle
Angle.
The beneficial effects of the utility model are：The utility model is simple in construction, and drift is removable by helicitic texture with punch-pin
Formula connection is unloaded, the stamping press to metal plate can be buffered, avoid fracture of the metal plate in punching course, while can be rushed according to different
Swaging shape replaces drift, and use cost is low.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the metal plate punching mould of replaceable drift of the utility model；
The mark of each part is as follows in accompanying drawing：1st, punch-pin, 2, drift, 3, cavity plate.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
Referring to Fig. 1 the utility model embodiments includes：
A kind of metal plate punching mould of replaceable drift, including：Punch-pin 1, drift 2 and cavity plate 3, the punch-pin 1 and cavity plate 2
It is correspondingly arranged up and down, mounting hole is offered on the lower surface of the punch-pin 1, internal thread knot is machined with the inwall of the mounting hole
Structure, the drift 2 include upper end cylinder installation portion and the lower end being fixed together with the upper end cylinder installation portion
Pressing part, the upper end cylinder installation portion is removable to be arranged in the mounting hole, and the upper end cylinder installation portion
The external thread structure to be cooperated with the female thread structure is integrally machined on periphery wall.
Wherein, the angle that the both sides side of the lower end pressing part connects with lower surface is fillet, two inner sides of the cavity plate 3
The angle that face connects with upper surface is also fillet, using fillet structure, during punching press, has buffered the stamping press to metal plate, has avoided metal plate
Fracture in punching course, improves stamping quality.
During work, metal plate is placed on the upper surface of cavity plate 3, punch-pin 1 drives drift 2 to move down, drift 2 and cavity plate 3
Metal plate punching is molded by contact, shape that such as need to be different to metal plate punching, as long as replacing the structure of drift 2.
The utility model provides a kind of metal plate punching mould of replaceable drift, and simple in construction, drift passes through with punch-pin
Helicitic texture detachable connection, the stamping press to metal plate can be buffered, avoid fracture of the metal plate in punching course, while can be with
Drift is replaced according to different punching press shapes, use cost is low.
Embodiment of the present utility model is the foregoing is only, not thereby limits the scope of the claims of the present utility model, it is every
The equivalent structure or equivalent flow conversion made using the utility model specification and accompanying drawing content, or be directly or indirectly used in
Other related technical areas, similarly it is included in scope of patent protection of the present utility model.
