Machining device used for manufacturing pipeline through powder forming

Abstract

The invention discloses a machining device used for manufacturing a pipeline through powder forming. The machining device is characterized by comprising a tubular outer mold and an inner mold; and an upper mold cover with a groove and a lower mold cover are arranged at the two ends of the outer mold, an elastic outer mold is arranged in the outer mold, a mold cavity filled with tetrafluoropolyethylene powder is formed between the elastic outer mold and the inner mold, and a cavity is reserved between the groove and the end face of the inner mold. According to the machining device used for manufacturing the pipeline through powder forming, the upper mold cover with the groove is arranged, the inner mold and the outer mold are in cooperation for powder filling to manufacture a pipeline piece with a flange, and through movement of the inner mold capable of moving relative to the outer mold, the pressure of the elastic outer mold to the tetrafluoropolyethylene powder can be in all directions without dead corners; and a manufactured flange straight pipe is excellent in structure and performance, the device adopting the scheme is high in production efficiency and simple in process, and meanwhile the defects and problems of flange pipelines manufactured in the prior art at connecting corners are avoided.

Description

Technical field[0001]The present invention is a technical field, and a processing apparatus for a powder molding manufacturing pipe.Background technique[0002]F4 is one of the world's most resistant corrosion materials, and it is absolutely clean and non-toxic, F4 pipes, and the lined F4 products such as reactor, tower, storage tanks, etc. in chemical industries and food production. The use of F4 products is very wide. If a large number of production applications, it will make the traditional heater used in many years, not only make many new process high-efficiency projects that have been the high-temperature strong corrosion reaction that have been solved, but also have a company. The production speed is also greatly accelerated, greatly increasing value, gaining huge economic benefits.[0003]The current use of tetrafluoropolymer, but generally only as a straight tube, or the process step of adding two end flanges after the production, it is realized that there is a straight tube pip...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a processing device for powder molding to manufacture pipelines, which has a one-time molding and pressing method, in order to solve the problems of complicated manufacturing process and weak connection corners in the prior art. Flange pipes, and avoid the defects of flange pipes made by traditional technology
