Punch-pin, top plate, template composition；Part of the lower die is by die holder, drawing punch-pin, blanking die, stripper, guide rod, mandril, rubber support
Plate forms；The die shank is mounted on by screw above upper mold seat, and the backing plate and blanking punch are used by turret head articulation hole
Bolt is fixed on the lower section of upper mold seat, and the head of the piercing and flanging punch-pin is stuck between die shank and backing plate, and the knockout rod is worn
It crosses die shank to contact with piercing and flanging punch-pin, the drawing cavity plate is fixed below template, and the drawing cavity plate is located at blanking punch
With the inside of backing plate, the upper mold seat lower section is provided with guide sleeve, and the stripper is mounted on by unloading bolt under upper mold seat
Side；The drawing punch-pin is mounted on the top of die holder by screw, and the blanking die is mounted on by pin on die holder
Side, the rubber supporting plate are connected to the lower section of die holder by liftout screw, and the mandril connects across die holder with blanking die
It touches.
Specifically, there are spaces, the template between the backing plate and drawing cavity plate to pass through backing plate and top plate contact.
Specifically, the lower end of the piercing and flanging punch-pin is cylindrical punch, which is three-stage outer diameter from down to up
The structure being sequentially increased.
Specifically, the die holder offers waste material dropping channel.
Specifically, being provided with discharging rubber between the upper mold seat and stripper, top is provided among the rubber supporting plate
Expect rubber.
Rubber can increase buffering, lower abrasion, extend die life.
In conclusion the present invention, as a result of said program, the present invention has the following advantages：
The present invention in a mechanical movement by disposably completing the blanking and drawing punching of product and in-flanges work
The drawbacks of work needs 4 molds so as to overcome the prior art, and at least 4 procedures complete blanking and drawing punching and in-flanges.By
In in same mold, a process completes four procedures by one-time positioning, not only saves the manufacture of 3 molds, significantly
The production efficiency of product is improved, reduces the manufacture cost of product, and also improves the machining accuracy of product.
