The result shows that the punch-force increases with the increasing of the hydraulic pressure, the punch diameter and the thickness of the tube.
结果表明:管内液体压力增加、冲头直径增加、 材料壁厚增加都会使冲头推力增大;
The quality of the internal surface can be greatly improved and the punch force can be significantly reduced by using inner set hose.
内置软管可以有效改善管材的内表面质量,并显著减小冲头推力。
The end of the upper cover is connected with the U-shaped bracket by a shaft, which is used for applying the force on the upper cover by users and then transferring the force to the punch.
