Description

A kind of blowing device of high-speed stamping die

Technical field

The present invention relates to the high-speed stamping die technical field, especially a kind ofly be arranged on the high-speed stamping die and the blowing device that is connected with the source of the gas of external controllable system break-make.

Background technology

When utilizing high velocity ram machine and high speed die production part, owing to the speed that stamps out shaped article is very fast, if the speed that draws off of shaped article does not catch up with; Just cause laminating of product easily; Damage in type product by pressure, the meeting mold damage causes enormous economic loss when serious.

Discharge method is to adopt compressed air the product mould that blows off preferably at present; As disclosing a patent No. on June 24th, 2009 is that ZL200820161706.6, name are called the patent of invention of " a kind of horizontal punching machine "; It comprises upper die and lower die, tup and workbench, and counterdie is fixed on the workbench, and patrix is located on the tup; Upper die and lower die are provided with blowing device, and this blowing device is located at the top between the upper die and lower die; This blowing device is applicable to that patrix does the structure of side-to-side movement with respect to counterdie, because the weight of this kind structure through the pressure of blowing and product self is easily the product mould that blows off; But this blowing device is not suitable for the structure that patrix moves up and down with respect to counterdie; The discharge way that patrix moves up and down with respect to counterdie will overcome the deadweight of product itself on the one hand; Also to make the blow-off direction of product reasonable; Product can not blow off mould or unreasonable other position that is stuck in mould of product blow-off direction can appear during like the discharging of the frame mode that is used for patrix and moves up and down with respect to counterdie in above-mentioned disclosed blowing device; Cause laminating of product, damage in type product by pressure, and then mold damage.

Summary of the invention

The technical problem that the present invention will solve provides a kind of blowing device of high-speed stamping die, has improved to draw off reliability of products, effectively protects mould and in type product, and applied widely.

For achieving the above object; Technical scheme of the present invention is: a kind of blowing device of high-speed stamping die, comprise the stripper that is contained in the patrix bottom, the concave template that is contained in counterdie top, and stripper is provided with the air blowing nail that can stretch out its lower surface and can move up and down; The position of air blowing nail is in the rear portion of product punch forming position; The blow centre of nail is provided with passage, and the gas outlet of passage is downward-sloping and towards the rear portion of product punch forming position, is provided with the interface channel from external communications to the nail passage of blowing in the patrix; Described interface channel is connected with the source of the gas of external energy control break-make; The ejector beam that can stretch out its upper surface and can move up and down is housed on the concave template, and the bottom of ejector beam is provided with spring, ejector beam be in product punch forming position below.

Further improve, the top of described air blowing nail is provided with spring, improves the reliability that the nail of blowing moves down.

Further improve, the passage in the middle of the described air blowing nail has two, and the gas outlet of two passages guarantees the direction of motion when product blows off mould towards the both sides at the rear portion of product punch forming position.

The gas outlet of passage and the angle of stripper lower surface are 78～82 ° in the middle of the preferred said air blowing nail, better the product mould that blows off.

When said product punch forming position when being a plurality of; The quantity of said air blowing nail and ejector beam is corresponding with product punch forming position; Each rear portion, product punch forming position is provided with at least one nail of blowing, and is provided with at least one ejector beam below each product punch forming position.

The present invention is owing to be equipped with the ejector beam that can stretch out its upper surface and can move up and down on the concave template; The bottom of ejector beam is provided with spring; Ejector beam be in product punch forming position below, when upper die and lower die were in die opening state, ejector beam moved up under spring action; Ejector beam leaves the concave template upper surface to molded product top; Adhesion appears in the upper surface that prevents molded product and concave template, being provided with simultaneously the nail of blowing at the rear portion of product punch forming position, and the gas outlet of the middle passage of the nail of blowing is downward-sloping and towards the rear portion of product punch forming position; The compressed air that blows out from the gas outlet of the middle passage of the nail of blowing just beat at the rear portion of product can be reliably the product mould that blows off, effectively protect mould and in type product.

The present invention is applicable to when patrix moves up and down with respect to counterdie or the discharging of patrix when doing side-to-side movement with respect to counterdie, and is applied widely.
