Detailed Description
In order to more clearly illustrate the embodiments of the present application or the technical solutions in the prior art, the present invention is further described below with reference to the accompanying drawings and specific embodiments.
Example 1
The novel tooling clamp for preventing the powder metallurgy from being adhered to the bottom surface of the cylinder cover as shown in fig. 1 comprises a first hard alloy plate 100 and a second hard alloy plate 200 which are matched for use. The first cemented carbide plate 100 and the second cemented carbide plate 200 are both rectangular flat and are demagnetized. The powder metallurgy which is adhered on the clamp due to magnetism and is not easy to fall off can be reduced by adopting demagnetization treatment.
The opposite side edges of the first hard alloy plate 100 and the second hard alloy plate 200 are respectively provided with 3 longitudinally arranged hollow structures 300, the contact lines of the first hard alloy plate 100 and the second hard alloy plate 200 are used as central axes, the hollow structures 300 are arranged in a crossed and zigzag manner, and the width of each hollow structure 300 accounts for 1/5-1/4 of the width of a single plate. Adopt the design of sawtooth, but the position of fretwork simultaneously of cylinder cap bottom surface and conducting bar's area of contact can effectively reduce to add man-hour on the one hand drainage cutting fluid, avoids remaining on the cylinder cap bottom surface in the powder metallurgy adhesion in cutting fluid, and on the other hand can guarantee that the intensity of anchor clamps is from not influencing its life, adopts novel carbide material to further promote its life simultaneously.
The edges of the hollow structures 300 are processed by round corners, so that the cylinder cover can be effectively prevented from being scratched in the pushing and pulling process.
