Multi-stroke shaping mill

Abstract

The invention provides a multi-stroke shaping mill which is mainly characterized in that a drilling crew is mainly provided with a chopper, a female die device, a clamping device, a backlash device, a male die device and a frontlash device, wherein two opposite side surfaces of a notch on the clamping part of the clamping device are provided with diagonal planes to lead a frontlash rod on the male die device; when the frontlash rod is not aligned with the mold cavity positions of the clamping device and the female die device, the frontlash rod impacts the diagonal planes of the clamping part,the clamping device shakes, and an operator can find that a plurality of centers are not aligned in real time so as to carry out adjustment, the deformation and damage of the frontlash rod and the clamping device can be avoided; the clamping device is stable when clamping blank, and the blank is quickly moved to the next female die position to be stamped; and the action of the frontlash device can cause the blank on the frontlash rod of the male die device to be successively discharged so as to obtain the efficacy of one-stop operation, multiple stamping and quick shaping of fasteners.

Description

technical field [0001] The present invention relates to a molding machine, in particular to a multi-stroke molding machine, which cuts metal wires into blanks, and transfers the blanks to the master mold device one by one by a clamping device for stamping. To achieve the purpose of stamping rapid prototyping fasteners for multiple times of consistent operations. Background technique [0002] For general forged articles (such as fasteners), the coiled metal wire is mainly transported to the forming machine, the metal wire is cut into a blank by the cutting device of the forming machine, and then the blank is clamped by the clamping device to the In front of the female mold base corresponding to the male mold base, through several front punches on the male mold base of the stamping mechanism, the blanks are sequentially punched into the mold cavities of the female molds, and the mold cavities of the female molds are equipped with The rear punch pushes out the stamped blank in...

Problems solved by technology

[0004] And known clamping device 2, please refer to image 3 As shown, a hollow shell seat 20 is mainly provided, and a driving rod 21 is pierced on the shell seat 20. The driving rod 21 can be driven by a power source (not shown in the figure) to move up and down, and the 20 is provided with two intersecting clamping arms 22 driven by the drive rod 21 and pivoted on the shell base 20. The lower ends of the arms 22 are respectively provided with jaws 24, and the opposite inner sides of the two jaws 24 are oppositely provided with a gap 25 for clamping the blank A. The jaws 24 hold the blank A and move it to the position of the next female mold B. When the male mold is stamping towards the female mold, the driving rod 21 drives the clamp arm 22 together with the jaws 24 to release the blank A and lift it up. move away, and the known clamping device 2 needs to accurately cooperate with the actions of clamping, transferring, placing and punching the blank A, and the assembly needs to be extremely precise. If the position of the clamping device 2 clamping the blank A is slightly If there is an offset, the front punch of the male mold will hit the jaws 24 of the clamping device 2 during stamping, causing deformation and damage to the jaws 24, and the blank A cannot be stably clamped, thereby affecting the Transfer of billet A
