Teflon bar forming device

Abstract

The invention discloses a teflon bar forming device. The teflon bar forming device comprises a positioning step and a flange plate which are provided with bolt holes. Bolts penetrate the bolt holes to connect the positioning step with the flange plate together. The positioning step is connected with a positioning device provided with a plurality of positioning holes. A machine head is arranged on the positioning device and provided with a material conveying port. The material conveying port is provided with a plurality of positioning grooves. The flange plate is connected with a material conveying barrel. A material conveying channel is arranged in the material conveying barrel. The material conveying barrel is connected with a die plate. A rotation shaft is arranged in the die plate. The die plate is connected with a shaft sleeve connected with a bar forming pipe. An inner rod is arranged in the bar forming pipe and is of a hollow structure, and the bar forming pipe is connected with a plug. Through the arrangement of the positioning device and the multiple positioning grooves, the forming device and a material conveying device are firmly connected together, and the situation that connection of the forming device and a feeding device is not easy, and material leakage happens is avoided.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a polytetrafluoroethylene rod forming device. Background technique [0002] PTFE rod is an unfilled PTFE resin suitable for processing various gaskets, seals and lubricating materials working in corrosive media, as well as electrical insulating parts used at various frequencies. (may contain recycled polytetrafluoroethylene resin) Rods formed by compression molding, paste extrusion or plunger extrusion. There are two types of PTFE rods: push rods and molded rods. Among known plastics, PTFE has the best chemical corrosion resistance and dielectric properties, and can be used at temperatures ranging from -180°C to +260°C. , and has the lowest coefficient of friction, mainly suitable for some long products and mechanical parts of non-standard specifications. [0003] Now on the market, PTFE rods are generally produced by extrusion molding. Extrusion molding is also called e...

AI Technical Summary

Problems solved by technology

However, there are still many deficiencies in the current market for PTFE rod forming devices. For example, the forming device and the feeding device are not easy to connect, and the connection is prone to material leakage, etc., the structure is complex and expensive, the production efficiency is low, and the forming is cooled. After the bar is not easy to take out, etc.
