Screw roll fixed pitch stretching device

Abstract

The screw roll fixed-pitch stretching equipment consists of motor, high-speed belt drive stage, low-speed belt wrive stage, driving rubber roller, differential rubber roller, driving conic roller, driven conic roller, speed-regulating screw, shaft and bearings. The motor drives the small belt pulley of high-speed belt drive stage; the driving conic roller, the large belt pulley of high-speed belt drive stage and the driving rubber roller are on the drive shaft; the driven conic roller and the small belt pulley of low-speed belt drive stage are on the middle shaft; the large belt pulley of low-speed belt drive stage and the differential rubber roller are on the driven shaft; there is speed regulating screw with control handle installed between the driving conic roller and the driven conic roller; and the bearings are mounted on the box.

Description

Technical field: [0001] The invention proposes a helically coiled constant-pitch stretching device, specifically a special device for preparing metal rubber products. Background technique: [0002] Metal rubber products are structural parts made of metal wires with a diameter of 0.05-0.3mm as raw materials and formed by special preparation processes. They can be widely used in damping reduction under special working conditions such as high temperature, low temperature, large temperature difference, high vacuum and corrosive environment. Vibration, sealing, filtering and heat conduction structures. In the fields of aviation, aerospace, automobile industry and special couplings, metal rubber has become the best substitute for ordinary rubber. The basic steps of preparing the metal-rubber member are as follows: first, select a suitable metal wire and roll it into a helical coil (the shape of the helical coil is like a slender tension spring); secondly, according to the structu...

Problems solved by technology

The research and development of metal rubber products in my country is still in its infancy. During the development process, the fixed-pitch stretching of spiral coils is mostly done manually. Manual stretching of spiral coils is not only labor-intensive, but also causes a huge waste of human resources. Affected by human factors, it is difficult to ensure the consistency of the pitch of the spiral coil after stretching, which directly affects the uniformity of the bonding force between the spiral coils and the stability of product performance during the forming process of metal rubber components.

Therefore, it is not suitable for mass production of metal rubber products to perform fixed-pitch stretching of spiral coils by manual methods.
