A composite tube edge molding device and molding method

Abstract

The invention discloses a composite pipe flanging molding device and a molding method. Specific arc-shaped structures are adopted in a feeding frame movable baffle and a discharging frame movable baffle of the molding device, and a single composite pipe is pushed into a station and pulled out. Die moving mechanisms drive a heating die and a molding die to move so as to carry out heating and flanging molding. In the heating process, an elevated rotating supporting wheel set drives the composite pipe at the station to rotate at a low speed. In the flanging molding process, the composite pipe is clamped and positioned through a clamping mechanism. According to the composite pipe flanging molding device, the two novel die moving mechanisms are provided and include a linear moving type die moving mechanism and a swing moving type die moving mechanism. Meanwhile, the method for conducting composite pipe flanging molding with the device is provided. Compared with the prior art, the device has the beneficial effects of being convenient to operate and high in automation degree and saving the number of persons and labor; and the flanging molding efficiency is high, the quality is good, and the composite pipe flanging molding device and the molding method can be suitable for flanging molding of various composite pipes.

Description

technical field [0001] The invention relates to a compound pipe forming device, in particular to a device and a forming method for preheating and flanging the inner lining of the pipe end of the compound pipe. Background technique [0002] Engineering plastic pipes have the characteristics of light weight, strong corrosion resistance, and small fluid resistance, and are widely used in engineering fields such as tap water and electrical engineering. Limited to poor pressure resistance and weak impact resistance, engineering plastic pipes are generally used for the transportation of low-pressure fluids. [0003] In order to broaden the application range of engineering plastic pipes, composite pipes have been developed. This kind of composite pipe uses PVC, PE, PPR, etc. as the inner liner, and uses glass fiber winding pipe or metal pipe as the outer pipe. Due to the strong pressure bearing capacity and wear resistance of glass fiber and metal, the pressure bearing capacity o...
