7results about How to "Smooth stripping" patented technology

The utility model discloses a mould structure of slider forming relates to hardware punch die field, including upper die holder, opposite lower die holder opening, closing die movement, upper backing plate is fixed with upper die holder, slider mounting subassembly is slidably installed on the upper backing plate, and the slider is embedded and installed on slider mounting subassembly, the material mechanism of feeding, its one end is fixed on the upper die holder, and its other end penetrates the upper backing plate and is topped in the slider top, makes slider relative slider mounting subassembly sliding, and lower backing plate is at setting the locating plate on it, is used for positioning, and places former process spare, and the locating plate center is embedded and installs lower die forming block, and lower die forming block center is embedded and installs lower die shaping block, when upper die holder and lower die holder closing die, slider and upper die forming block, lower die forming block and locating plate compression tight cooperation, will former process spare punch and form this process spare. The utility model can better adapt to product special shape and size requirement, guarantees product structure stability and reliability.

The utility model discloses a bending die stripping and pushing-out device, a left bending punch and a right bending punch on an upper die can tightly abut against material sheets extending out of the outer portions of the left side and the right side of a bending male die of a lower die to enable the material sheets to be bent downwards, and a stripping device on the lower die can upwards jack up a bent and formed product in the die opening process. A notch-shaped left forming block containing groove and a notch-shaped right forming block containing groove are formed in the two sides of the upper end of the bending male die respectively, a left forming block and a right forming block are movably arranged in the left forming block containing groove and the right forming block containing groove respectively, and a left reset driving device and a right reset driving device in the lower die drive the left forming block and the right forming block to move to the forming position and the separating position respectively in the die closing state and the die opening state. The left side face of the left forming block and the right side face of the right forming block located at the forming position are in tight and flat contact with the left side bent edge and the right side bent edge of a bent product correspondingly, and gaps are formed between the left side of the left forming block and the left side bent edge of the bent product and between the right side of the right forming block and the right side bent edge of the bent product and between the right side of the left forming block and the right side bent edge of the bent product correspondingly. According to the invention, smooth stripping of products can be ensured.
