Description

Technical Field

[0001] The present invention relates to the technical field of cable tray manufacturing, in particular to a device and method for manufacturing an antistatic cable tray. Background Art

[0002] Cable trays are composed of trough-type, tray-type or ladder-type straight sections, bends, tees, four-way components, as well as supports and hangers. A rigid structural system with close support for cables is called a cable tray. Cable trays are divided into trough-type, tray-type, ladder-type, grid-type and other structures, and are composed of supports, supports and installation accessories. Among them, trough-type cable trays are mainly produced in batches, so they need to be produced quickly through manufacturing equipment. During the manufacturing process of cable trays, the cut metal plate edges need to be bent, but the existing bending methods are to place the metal plate on the surface of the bending machine, and then use the bending machine to bend the metal plate.

[0003] In current wiring projects, a huge amount of cables are used, and various cables are crisscrossed in the city. Once a fire occurs, the consequences will be disastrous. There are many causes of fire, among which static electricity and external open flames are the main causes of fire. Therefore, the use of reliable fire-proof and static-conducting materials can reduce the probability of fire.

[0004] Conventional antistatic cable trays are usually sprayed with antistatic materials on their surface after the cable trays are processed and bent, and then baked to form an antistatic layer. However, this technology needs to be carried out after bending, and the cable trays need to be transported and processed separately. In addition, the spraying of antistatic materials is usually done manually, which is inefficient. It is impossible to spray and bake the cable trays immediately after bending to prepare antistatic cable trays. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide an anti-static cable tray manufacturing device and method to solve the problems raised in the above background technology. After the metal plate is pressed into shape by a pressing frame, the pushing assembly is pushed into the inside of the baking oven along the base. When passing through the spraying assembly, the nozzles on the inner frame and the outer frame simultaneously spray anti-static material on the inner and outer surfaces of the cable tray along the path, thereby improving the processing efficiency of the cable tray, reducing the time spent on manual operation, and making the production of anti-static cable trays more efficient.

[0006] In order to achieve the above object, the present invention is implemented through the following technical solution: a method for manufacturing an antistatic cable tray, the manufacturing method comprising the following steps:
