[0035] Working principle: The material is put into the molding lower die, which is positioned by the guide strip 31 and the head positioning block 25, and supported by the ejector plate 29. After the start switch is pressed, the TCL50-175S three-axis cylinder 12 drives the slider strip insert 6 and the slider strip 9 to close with the front part 4 of the molding punch and the rear part 5 of the molding punch. The molding upper die moves downward with the upper slider of the hydraulic press body 37, and the external molding insert 28 on the molding lower die is first formed at the outer side of the fork arm. Then the molding upper die moves upward with the slider of the hydraulic press body 37, and hits the upper limit travel switch. The signal is transmitted to the signal control box 36, and the TCL50-175S three-axis cylinder 12 drives the slider strip insert 6 and the slider strip 9 to open with the front part 4 of the molding punch and the rear part 5 of the molding punch. There is a cylinder sensing magnetic switch at the opening and closing position. 19 control, after it is in place, the signal is transmitted to the signal control box 36, and the molding upper mold follows the upper slider of the hydraulic press body 37 downward again. After hitting the material and the ejector plate 29, it continues to move downward and combines with the head molding insert 26 and the internal molding insert 27 of the molding lower mold to form the inner edge and head of the fork arm. After that, the molding upper mold moves upward with the slider of the hydraulic press body 37, the ejector plate 29 is lifted by the DCX320-75 nitrogen spring 33 and the unloading plate guide block 32 is lifted by the DCX320-75 nitrogen spring 33, and the upper slider of the hydraulic press body 37 hits the upper limit travel switch again, and the signal is transmitted to the signal control box 36. The TCL63-500S three-axis cylinder 13 receives the signal and drives the push strip fixing block 15. The push strip 16 ejects the formed fork arm and is retracted here. This back and forth is completed.
