Punching equipment for processing shuttle peg sleeve

Abstract

The invention belongs to the technical field of cop latch sleeve machining, and particularly relates to punching equipment for cop latch sleeve machining. The side end of an electric push rod is fixedly connected with a clamping plate; the inner side walls of the clamping plates are fixedly connected with buffering pads. The side end of the buffer pad is fixedly connected with an elastic piece, and the other end of the elastic piece is fixedly connected to the inner side wall of the clamping plate. The shuttle peg sleeve is placed at the side end of the clamping plate, then the electric push rod is opened, the clamping plate is driven to move towards the middle part, the shuttle peg sleeve is clamped and fixed, when the clamping plate extrudes the end part of the shuttle peg sleeve, the end part of the shuttle peg sleeve extrudes the buffer cushion, so that the buffer cushion is stressed to be bent, and a protection effect is achieved; the elastic piece is extruded to generate elastic force for buffering, so that the buffering effect on the shuttle peg sleeve is improved, and the problem that the quality of finished products is affected due to shaking of the shuttle peg sleeve in the machining process is solved.

Description

technical field [0001] The invention relates to the technical field of bobbin case processing, in particular to a punching device used for bobbin case processing. Background technique [0002] During the working process of the sewing machine, the phenomenon of running out of needles is almost likely to occur. This is because the amount of bobbin thread drawn out by the suture thread of the bobbin case under the action of the tension adjustment spring is small, and the sewing machine starts to sew or automatically breaks the thread and then sew again. When making, the upper thread cannot be firmly grasped with the bottom thread, and the needle will run short. [0003] In the current prior art, when the existing bobbin sleeve is punched, the end of the bobbin sleeve is in the shape of an arc, resulting in the problem that the bobbin sleeve is prone to shaking during the punching process of the punching equipment, which leads to The punching accuracy of the punching equipment ...

AI Technical Summary

Problems solved by technology

[0004] In order to make up for the deficiencies of the prior art and solve the problem that the existing bobbin case is prone to shaking when the end of the bobbin case is arc-shaped during the punching process of the punching equipment , which in turn causes the punching accuracy of the punching equipment to be affected, reducing the quality of the finished product of the bobbin case. The present invention proposes a punching device for bobbin case processing
