Punch forming machine for double-hook on antiskid chain

Abstract

A punch molding machine with dual hook on the antiskid chain comprises frame with linear alignment structure and intermittent feeding mechanism, positioning linear material on the frame and locating frame on the locating frame, No.1 action mechanism vertically from top to bottom punching above the locating frame, whose lower two sides having No.2 action mechanism punching from sides to the middle, and the No.3 action mechanism punching from fore and aft horizontally at the front of the locating frame, with the No.2 action mechanism formed by same punching devices symmetrical at both sides, No.1 and No.2 action mechanism on the same punching phase, with the No.3 action mechanism punching vertical to the said punching phase. Using simple arrangement of molds, it can get the dual hook product from linear material with automatic running, high efficiency, safe and reliable.

Description

technical field [0001] The invention belongs to the field of stamping and forming equipment for wire (rod) materials, in particular to a stamping and forming machine for manufacturing double hooks and similar parts used on anti-skid chains of automobiles. Background technique [0002] The automobile anti-skid chain is composed of side chains fixed on both sides of the tire and a cross chain fixedly connected to the two side chains through double hooks to play an anti-skid effect. On the side chain, the hook belly (A) part is used to hang buckle cross chains. In the prior art, the manufacture of double hooks usually involves first straightening the disc-shaped wire rod, cutting the material according to the size and length of the double hooks, and then putting the small section of material into the die groove of the punch press to punch it into a U shape (forming the belly part of the hook), and then Put the U-shaped half-ring material into another die groove and punch it in...

Problems solved by technology

In the prior art, the manufacture of double hooks usually involves first straightening the disc-shaped wire rod, cutting the material according to the size and length of the double hooks, and then putting the small section of material into the die groove of the punch press to punch it into a U shape (forming the belly part of the hook), and then Put the U-shaped half-ring material into another die groove to punch it into double hooks (forming the claw part). This production method is labor-intensive, low in efficiency, poor in safety, and unstable in quality.
