Abstract

The invention relates to a tooth selection and positioning mechanism of a metal zipper punching machine. The invention mainly solves the problem that the number of teeth on the zipper selected by the existing gear punching machine deviates. It is characterized in that a positioning blade (4) is fixed on the slider (3), an air cylinder (5) and a swing arm (6) are installed on the ram (2), and the top of the other end of the swing arm (6) is in contact with the air cylinder ( 5) The piston rod corresponds to and is provided with a spring (16) below; the left positioning block (8) and the right positioning block (9) are provided with adjustable limiters (10), and the right positioning block (9) and the sliding A reset extension spring (11) is arranged between the pillows (2); a detection switch (12) is fixed on one side of the track (1), and the detection switch (12) can control the zipper conveying mechanism to stop after the ram (2) is in place. The tooth selection and positioning mechanism of the metal zipper punching machine is positioned accurately, and the number of teeth of each zipper section is equal, which avoids the deviation of the number of teeth.

Description

technical field [0001] The invention relates to a positioning device for punching metal zipper teeth, in particular to a tooth selection and positioning mechanism for a metal zipper punching machine. Background technique [0002] During the processing of the metal zipper, teeth are selected according to the length of the required zipper, and then part of the teeth is removed by a gear punching machine to form several zippers of equal length, and then the upper stop and the lower stop are installed. The existing gear punching machine includes a mould, a gear punching knife and a tooth selection mechanism. The zipper blank is located above the mold and can move from one side to the other. After the length is selected by the gear selection mechanism, the zipper stops, and the gear punching knife falls to move the zipper. The teeth on the billet are washed off. Because the cloth tape of the zipper blank has a certain degree of elasticity, the zipper has a certain inertia and wi...
