Copper strip sewing machine

Abstract

The invention relates to a sewing machine, in particular to a copper strip sewing machine. The copper strip sewing machine comprises a frame, an upper installing plate and a lower installing plate, wherein the upper installing plate and the lower installing plate are arranged on the frame. A plurality of upper punching heads penetrating through an upper mold vertically and downwardly are fixed tothe bottom of the upper installing plate. A plurality of lower punching heads penetrating through a lower mold vertically and upwardly are fixed to the lower installing plate. The upper punching headsand the lower punching heads are arranged in a staggered mode in the width direction of copper strips. Threading holes communicating with each other are formed in adjacent end surfaces of the upper and lower punching heads. Notches vertically communicating with the threading holes are formed in end portions of the upper and lower punching heads. Copper wires are threaded through all the threadingholes from one side. When the upper punching heads and the lower punching heads are separated from each other, the copper wires are threaded out of the notches in the upper and lower sides and kept in interlaced punching holes in the two layers of copper strips, and therefore firm sewing is achieved. Moreover, threading devices for threading the copper wires through the threading holes are arranged on the frame and are easy and convenient to operate, and therefore semi-automatic operation and control are achieved, and labor resources are saved.

Description

technical field [0001] The invention relates to a sewing machine, in particular to a copper tape sewing machine. Background technique [0002] In the production of some metal strip products, it is necessary to connect the ends of two rolls of metal strips to facilitate the assembly line operation, and the existing connection methods are mainly welding, gluing and manual sewing. [0003] At present, the Chinese patent document with the authorization announcement number CN2288028Y in the prior art discloses a metal strip sewing machine, which includes a movable beam installed on a frame, a driving oil cylinder for the movable beam, and upper and lower punching dies. One of the punches is fixedly connected to the movable beam, the other is fixedly connected to the frame, and the punching and shearing edges of the punching die are all stepped from the punching direction. When stitching, the two strips are overlapped, and a row of stepped incisions are punched and cut, and then ...

AI Technical Summary

Problems solved by technology

[0004] However, although the method of interlocking the step-shaped incisions is convenient and efficient, when the copper strips are too loose or the two strips are squeezed by external forces, it is easy to cause the joints to separate, thus causing the two strips to be disconnected. Connection, there is no strong connection such as threading and suturing, so a connection method that is both strong and simple and convenient is needed
