Device for shearing I-shaped structure of zipper

Abstract

The invention discloses a device for shearing an I-shaped structure of a zipper. The device comprises a machine base, wherein a punch die, a fixed die matched with the punch die, and a wire delivery mechanism are arranged on the surface of a worktable of the machine base; the punch die comprises front, rear, left and right clamping punching heads, and front, rear, left and right sliding ways corresponding to the front, rear, left and right clamping punching heads respectively; the shapes of the front, rear, left and right clamping punching heads correspond to the wire ways of a metal wire; the front, rear, left and right clamping punching heads are arranged in the front, rear, left and right sliding ways respectively and are connected with a clamping power device through a sliding block; the fixed die is fixed above the punch die; a wire passing hole matched with a section of the metal wire is formed in the center of the fixed die; and the wire passing hole is opposite to a clamping groove formed by clamping the front, rear, left and right clamping punching heads. The device for shearing the I-shaped structure of the zipper has high production efficiency and no metal fragments in the machining process.

Description

technical field [0001] The invention relates to a zipper I-code processing equipment, in particular to a zipper I-code cutting device. Background technique [0002] In the manufacture of metal zippers, the metal lower stopper on the metal zipper has a cross-section in the shape of "I", so it is called I-shaped code; before the I-shaped code is clamped and fixed at the end of the zipper chain, its cross-section is " X" letter-shaped metal parts, and these metal elements are cut one by one from the metal wire with "X" shape in cross section. At present, most of the I-character codes to be installed are cut from the metal wires one by one by hand with tools such as high-speed saw blades or grinding wheels. However, this method of manually cutting metal parts is time-consuming, labor-intensive, and inefficient. , At the same time, metal debris is generated during the cutting process, which wastes materials.
