Outside punch-pin, and upper plug, hydroabrasive and the piercing punch with end part seal are set gradually from top to bottom, and die case is mounted in
Lower prop portion beyond the Great Wall.
Method：The method through the following steps that realize：
Step 1: between sheet metal to be formed is placed in the lower surface and the upper surface of cavity plate for holding frame, and by metal to be formed
Plank clamps；
Step 2: being moved downward with faster speed promotion upper plug drive hydroabrasive and the piercing punch with end part seal
Sheet metal to be formed is acted on, so that sheet metal to be formed is occurred under the action of the piercing punch with end part seal disconnected
It splits, is separated into punching part and waste material；
Step 3: the piercing punch of end part seal to be carried, completely into cavity plate, piercing punch, waste material and lower plunger completely attach to
And after clamping, push upper plug that hydroabrasive is driven to continue to move downward with slower speed, the section progress for the orifice that liquidates is whole
It repaiies；
Step 4: pushing up lower plunger in turn repeatedly and pushing down on upper plug so that the section of punching part is in hydroabrasive
Repeated action under progressively reach ideal surface quality；
Step 5: plunger and appearance frame are removed from cavity plate top, the punching part after trimming is taken out, that is, completes a punching trimming
Composite forming processes.
The invention has the advantages that：
One, the present invention uses a kind of hydroabrasive, it is with solid particle abrasive material by viscoelastic high molecular polymer with certain
The semisolid with certain fluidity that ratio mixes can be used for being polished workpiece, deburring and rounded corner.
The sheet metal punching trimming compound molding device and method that this patent proposes, are this characteristic using hydroabrasive,
Two processes of punching and trimming are completed at the same time in same covering device；
Two, the present invention is for, for the needs of different punching sizes and cross section quality, selection is suitable in sheet metal blanking process
Abrasives and size, improve the cross section quality of blanking part；
Three, the present invention solves to have in technique, can increase input and the working hour of mold using punching plus trimming process, using fine
To punching process and the higher problem of equipment requirement, and provide that a kind of device is simple, the high sheet metal punching of production efficiency is whole
Repair compound molding device and method.
