Description

Annular blade cutting clamp Technical Field The utility model relates to the technical field of pneumatic clamps, in particular to an annular blade cutting clamp. Background The blade material of the blade special for the cutter wheel cutting machine is formed by adding diamond particles into powder alloy and pressing, the blade material is precious metal, the rim charge of the pressed blade is extremely narrow, the inner diameter and the outer diameter of the blade are required to be cut off for one circle, and the standard size and the concentricity of the inner diameter and the outer diameter are ensured, so that the purposes of saving the raw materials of the blade and improving the yield of products are realized. The existing blade cutting adopts the method that materials of finished products far larger than the final requirement are pressed first, then the clamp is used for pressing the outside of the materials for cutting, but the blade cutting and pressing clamp is used for pressing the products for cutting because the blade part pressed by the blade cutting and pressing clamp occupies more size of the blade and the pressing clamp also avoids the laser cutting head, so that the scheme needs more edge materials of the blade than about 6mm to press the products for cutting. The existing clamp scheme adopts a mode of covering and pressing on the blade to be cut, so that the stress on the part, which is subjected to pressing pressure, of the blade material is uneven with that of other parts, the warping phenomenon of the blade can occur, the cut blade is finally elliptical, and the rejection rate of the blade cutting is high. And the existing clamp schemes cannot accurately position the blade material, resulting in cut blade rings that are not the very middle portion of the blade stock and cut blades that are uneven in thickness. Disclosure of utility model The utility model provides an annular blade cutting clamp, which aims to solve the problems that the existing mode of pressing the blades in the processing process of the blades firstly causes more materials of the blades to be cut (which is not beneficial to saving the raw materials of the blades) and the yield of the final products is low.
