Abstract

The invention relates to wide polytetrafluoroethylene turning film ironing and slitting equipment and a machining method. A heating roller, a cooling roller, a cutting shaft, a winding roller and a plurality of guide rollers of the equipment are connected and fixed to a support; a turning film is guided into the heating roller through the first guide roller to be ironed, then, is cooled through the cooling roller and is guided to the winding roller; the cutting shaft is arranged at the front end of the winding roller, a cutting knife is arranged at the lower end of the cutting shaft; and the film is wound and tightened through the winding roller after being cut by the cutting knife. The machining method comprises the steps that (1) a tubular blank is pressed and then sintered; (2) the blank is turned into the film; (3) ironing and shaping is carried out; and (4) cutting and rolling is carried out. The wide PTFE turning base material film is ironed and shaped, the surface of the base material film is flat and smooth, the edge of the base material film is not curled, and operation is easy, so that a large amount of waste caused by the fact that the film is curled and cannot be used is avoided; and the base material film is cut in the machining process at the same time, so that the production time can be shortened, and the production efficiency can be improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, in particular to ironing and cutting equipment and a processing method for wide-width polytetrafluoroethylene turning film. Background technique [0002] Polytetrafluoroethylene has particularly superior characteristics among various plastics, because the polytetrafluoroethylene molecular chain contains C-F bonds and has a symmetrical structure. Due to the large F atom, the molecular chain of polytetrafluoroethylene presents a helical structure. , These structural features endow PTFE with excellent properties. Such as excellent dielectric properties, insulation, high heat resistance, chemical stability and weather resistance, etc. In the 1950s, some American companies applied PTFE materials to the production of high-frequency copper-clad laminates. After nearly 60 years of development, the manufacturing and molding processes of PTFE high-frequency copper-clad laminates have also bec...
