Description

A kind of multipurpose stamping die of anti-seat wear

Technical field

The utility model is related to stamping die field, more particularly to a kind of multipurpose stamping die of anti-seat wear.

Background technology

Punching press, be at room temperature, using the mold on forcing press to material apply pressure, make its generate separation or Plastic deformation, so as to obtain a kind of pressure processing method of required part.Stamping die is light with foot is lifted in current manufacturing industry The status of weight.

Present mold is typically all that stamping material is placed directly on pedestal and carries out stamping press, because shake in punching course Dynamic punch can inevitably generate certain offset and touch the undershoot material mouth of pedestal generates damage to pedestal, and replaces pedestal cost too It is high.Simultaneously in the prior art punch designed for integral type, updating maintenance is cumbersome, and can only a kind of product of shape of punching press, Limit the use scope of stamping die.

Utility model content

In order to solve the above problem of the prior art, damage, while same punching are not generated to pedestal in stamping press The various products of different shapes of equipment energy punching press are pressed, the utility model provides a kind of multipurpose stamping die of anti-seat wear Tool.

The utility model adopts the following technical solution, a kind of multipurpose stamping die of anti-seat wear, which is characterized in that Comprising upper module, lower module and pedestal, the lower module is fixed on by equally distributed six groups of fixing bolts on pedestal, upper mold Block center is connected with punch pedestal, and punch pedestal can be moved freely up and down by being connected with hydraulic cylinder, be contained on punch pedestal Threaded hole, punch are threadedly attached on punch pedestal, and ram bottom is less than the bottom of upper module.

Further preferably, the punch diameter is less than lower module die throat diameter.

Further preferably, the fixing bolt is lined with two panels elastomeric pad.

Further preferably, rewinding box is equipped with below the pedestal, rewinding box is aligned with pedestal punching, is completed for collecting The product of punching press.

Further preferably, the pedestal is firm using GT35 hard alloy, and lower module uses CrWMn high hardness alloy steels.

Compared with prior art, the utility model has the advantages that：

1st, connection lower module above pedestal, avoids contact of the punch with pedestal, can prevent the damage of pedestal, replaces and safeguards It is more convenient.It only needs to change when the product of other shapes is rushed and can be realized for the lower module of corresponding punching simultaneously.

2nd, because punch is movably connected on punch pedestal, punch of different shapes can be arbitrarily replaced, goes out arbitrary shape Product.

3rd, lower module is fixed using 6 groups of bolts, fixed effect is more preferably.Direction when replacing the punching module of special shape simultaneously More flexible control, it is easier to be mapped with punch.

4th, ram bottom is slightly below upper module bottom, and before punch. contact to product, upper module has been pushed down product and played Fixation prevents product from moving, beneficial to stamping press.

5th, the alloy rigidity that pedestal uses is higher than the hardness of lower module, and mutual stress more easy damaged is softer during punching press Lower module further protects pedestal.

Description of the drawings

Fig. 1 is the front section view of the utility model.

Fig. 2 is the top view of the utility model lower module.

It illustrates：1- upper modules, 2- pedestals, 3- lower modules, 4- punches, 5- punch pedestals, 6- fixing bolts

Specific embodiment

Below in conjunction with the accompanying drawings, the utility model is further described.

As shown in Figure 1, a kind of multipurpose stamping die of anti-seat wear, comprising upper module 1, lower module 3 and pedestal 2, Lower module 3 is fixed on by equally distributed six groups of fixing bolts 6 on pedestal 2, the stamping products directly on lower module 3 of punch 4, Contact of the punch 4 with pedestal 2 is avoided, can prevent the damage of pedestal 2.It is fixed to prevent that fixing bolt 6 loosens in punching course Two panels elastomeric pad is lined with below bolt.1 center of upper module is connected with punch pedestal 5, and punch pedestal 5 is by connection liquid cylinder pressure Under move freely, threaded hole is contained on punch pedestal 5, punch 4 is threadedly attached on punch pedestal 5, can arbitrarily be replaced not The punch 4 of similar shape goes out the product of arbitrary shape.When replacing different shape punch 4, also need to change under similary shape punching Module 3 for punch 4 is caused to align with punching, using equally distributed six groups of fixing bolts 6, is freely rotatable lower module 3.Punching First 4 bottom is slightly below the bottom of upper module 1, and so in punching course, before punch 4 touches product, upper module 1 has been pressed Firmly product plays fixation, prevents product from moving.

Specifically, 4 diameter of punch is slightly less than 3 die throat diameter of lower module, and in punching press, punch 4 will not touch lower module 3.

Specifically, 2 lower section of pedestal is equipped with rewinding box, and rewinding box is aligned with pedestal punching, and punching press is completed for collecting Product.

Specifically, pedestal 2 is firm using GT35 hard alloy, and lower module 3 is using the lower CrWMn high hardness alloys of hardness Steel, so in punching press loading process, what is easily deformed is softer lower module 3, preferably protects pedestal 2.

The above only expresses the preferred embodiment of the utility model, and description is more specific and detailed, but not Can the limitation to the utility model patent scope therefore be interpreted as.It should be pointed out that the ordinary skill people for this field For member, without departing from the concept of the premise utility, several deformations can also be made, improves and substitutes, these all belong to In the scope of protection of the utility model.Therefore, the protection domain of the utility model patent should be determined by the appended claims.
