Abstract

A kind of stamping die with heating function, including lower cavity die, heater and upper male mould, the open-mouth of the lower cavity die are equipped with material card slot, and the lower cavity die is internally provided with air pipe passway, and the groove of lower cavity die is surround by the air pipe passway in net structure.The air pipe passway is divided into upper channel and lower channel, and the upper channel is rectangle tracheae, and the lower channel is multirow proper alignment and evenly spaced U-shaped tracheae, and the U-shaped mouth of the upper channel and lower channel connects.The air pipe structure of the air pipe passway is divided into two layers, and internal layer is zinc-chromium coating, and outer layer is high strength steel.The air pipe passway is equipped with air inlet and gas outlet, and the heater connects air inlet and gas outlet respectively by two tracheaes.The upper male mould is located above lower cavity die, and cooperates with lower cavity die shape.The utility model on the basis of existing technology, improves the structure of lower cavity die, and mold can be heated before punching course, avoids product cracking failure due to the temperature difference.

Description

A kind of stamping die with heating function

Technical field

The utility model is related to a kind of stamping equipment, especially a kind of stamping die with heating function.

Background technology

Stamping equipment principle is by motor drive flywheel, and passes through clutch, and transmission gear drives crank connecting link machine Structure makes sliding block move up and down, and drawing die is driven to be molded steel plate or moulding material.Stamping die is preferably first right before use Stamping die is preheated, and otherwise the temperature difference between stamping die and product to be processed is big, can cause product ectonexine temperature Gradient increases, and forms thermal stress, product surface is made to be cracked or even crack, and traditional mode of heating is usually by material to be punched With fire calcine or flame calcining is carried out to mold, this mode is not only complicated for operation, and heating and it is uneven so that it is to be added Chemical product quality reduces.And some processed products need to be put into after punch process and one layer of protection are formed in certain melt Film, this needs product to be under certain temperature state.

Utility model content

In view of the above shortcomings of the prior art, the utility model provides a kind of stamping die with heating function.

To achieve the above object, the technical solution adopted in the utility model is：A kind of stamping die with heating function, bag Lower cavity die, heater and upper male mould are included, the open-mouth of the lower cavity die is equipped with material card slot, and the lower cavity die is internally provided with tracheae The groove of lower cavity die is surround by passage, the air pipe passway in net structure.The air pipe passway is divided into upper channel and lower channel, The upper channel be rectangle tracheae, the lower channel be multirow proper alignment and evenly spaced U-shaped tracheae, the upper channel with The U-shaped mouth of lower channel connects.The air pipe structure of the air pipe passway is divided into two layers, and internal layer is zinc-chromium coating, and outer layer is high-strength Spend steel.The air pipe passway is equipped with air inlet and gas outlet, and the heater connects air inlet with going out respectively by two tracheaes Gas port.The upper male mould is located above lower cavity die, and cooperates with lower cavity die shape.

Preferably, the lower cavity die outer surface is equipped with insulating layer.

Preferably, the lower cavity die on upper male mould with being equipped with threaded hole.

The utility model is simple in structure, on the basis of existing stamping die, improves the structure of lower cavity die, can be to mould Tool is heated before punching course so that product is more prone to be molded, and product is avoided surface checking or even to be opened due to the temperature difference It splits.

Specific embodiment

The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out Clearly, it is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work All other embodiments obtained shall fall within the protection scope of the present invention.

As Figure 1-Figure 4：A kind of stamping die with heating function, including lower cavity die 1, heater 2 and upper male mould 3, The open-mouth of the lower cavity die 1 is equipped with material card slot 4, and the lower cavity die 1 is internally provided with air pipe passway, and the air pipe passway is in net The groove of lower cavity die 1 is surround by shape structure.The air pipe passway is divided into upper channel 7 and lower channel 8, and the upper channel 7 is rectangle Tracheae, the lower channel 8 are the U-shaped mouth of multirow proper alignment and evenly spaced U-shaped tracheae, the upper channel 7 and lower channel 8 It connects.The air pipe structure of the air pipe passway is divided into two layers, and internal layer is zinc-chromium coating 11, and outer layer is high strength steel 12.It is described Air pipe passway is equipped with air inlet 9 and gas outlet 10, and the heater 2 connects air inlet 9 and gas outlet respectively by two tracheaes 10.The upper male mould 3 is located at 1 top of lower cavity die, and cooperates with 1 shape of lower cavity die.1 outer surface of lower cavity die is equipped with Insulating layer 5 prevents lower cavity die heat losses, while avoids the accidental injury that worker touches by arm.The lower cavity die 1 and upper male mould Threaded hole 6 is equipped on 3, lower cavity die 1 and the installation of upper male mould 3 is facilitated to fix.As shown in figure 5, certain processing mold is circle Mold, air pipe passway structure are also circular configuration, and the upper channel 7 is circular rings tracheae, and the lower channel 8 is multiple mutual Intersect and the equal U-shaped tracheae of angle, the U-shaped mouth of the upper channel 7 and lower channel 8 connect.

Steel plate to be processed is put to material card slot 4, starts stamping equipment, upper male mould 3 pushes, the High Temperature Gas in heater 2 Body enters from air inlet 9, is brought rapidly up air pipe passway, and upper male mould 3 is mutually squeezed with lower cavity die 1, and material is complete with lower cavity die 1 Contact, makes the temperature difference between material and mold relatively low, damaged so as to avoid material cracks, and material is made to be more prone to be molded, into Gas port 9 forms the circulatory system with gas outlet 10, ensure that the temperature of air pipe passway.Air pipe passway knot as described in Fig. 4 and Fig. 5 Structure makes mold heating effect more preferable, and operation is also simpler.Also, the product after punching press still has certain temperature, can be straight Connect and be put into certain melt (such as molten aluminum, zinc liquid, steel structure surface only spray zinc, it is aluminium-plated after, could really play anodic protection Effect), product surface is allow quickly to form protective film.
