Described automatic centering feed mechanism is diamond structure, symmetrical rotating cam mechanism, bevel gear structure or coaxial reverse thread feed mechanism.
Described coaxial reverse thread feed mechanism comprises trapezoidal slide block, trapezoid block pressing plate, guide roller and coaxial counterscrew, described coaxial counterscrew adopts bearing plate to be installed on the die shoe, coaxial counterscrew two the trapezoidal slide blocks that are threaded, trapezoidal slide block is installed on the trapezoid block pressing plate, the trapezoid block pressing plate adopts the trapezoid block hold-down screw to be fixed on the die shoe, and guide roller adopts the roller screw to be installed on the trapezoidal slide block.
One end of described coaxial counterscrew connects crank handle.
Described stamping-out sheet thickness scope 0.2-5mm.
The main points of this versatility blanking die are that plate is the guide benchmark with the geometric center of feeding direction.No matter how the width of plate changes, if both sides parallel can guarantee to send to be positioned at geometric center; The geometric center that realizes feeding direction is that the feed mechanism form of guide benchmark has a variety of.Such as: diamond structure, symmetrical rotating cam mechanism, bevel gear structure etc.Go for the feed mechanism of any material.Such as: metal blank, plastic cement plate, compound plate etc.; Be not limited to blanking die, can be used for the feed mechanism of any purposes.Such as: punching press, rolling, machined etc.; Can adopt manual and any power of employing and control form.
The beneficial effects of the utility model: novel structure, making are simply, easy to use, the location benchmark of feed mechanism adopts the geometric center of plate, no matter how the width of plate changes, as long as width can both process satisfactory product in allowed limits, thereby realize variation, many specifications, universal mold structure cheaply, be worthy of popularization.
