A rapid prototyping device and working method for polytetrafluoroethylene sheet

Abstract

The invention relates to the technical field of polytetrafluoroethylene processing, in particular to a rapid prototyping device and working method for polytetrafluoroethylene sheets, including a workbench and a blanking table, as well as a controller, a feeding mechanism, a forming mechanism and a conveying mechanism. The controller is fixed on one side of the top of the workbench, the feeding mechanism includes a discharge assembly and a push assembly, the discharge assembly is fixed on the top of the workbench and is located beside the controller, and the push assembly is fixed On the workbench and directly below the discharging assembly, the forming mechanism includes a carrying frame, a mold table assembly, a cooling assembly, a shifting and cutting assembly and a limit assembly, and the conveying mechanism includes a clamping assembly and a retrieving assembly. The present invention By adding PTFE raw materials to the lower hopper and manipulating the controller, rapid prototyping of PTFE sheets can be performed, which is safe, efficient, precise and controllable, and greatly improves the forming efficiency of PTFE sheets.

Description

technical field [0001] The invention relates to the technical field of polytetrafluoroethylene processing, in particular to a rapid prototyping device and a working method of a polytetrafluoroethylene sheet. Background technique [0002] PTFE board is made of PTFE resin by molding at room temperature, and then sintered and cooled. PTFE board is also called PTFE board or Teflon board. It is divided into molding and turning. There are two kinds of products, and their products are widely used. All kinds of PTFE products have played a pivotal role in the fields of national economy such as chemical industry, machinery, electronics, electrical appliances, military industry, aerospace, environmental protection and bridges, and have extremely superior comprehensive performance: High and low temperature resistance, corrosion resistance, weather resistance, high insulation, high lubrication, non-adhesion, non-toxicity and other excellent characteristics, the current efficiency of PTFE...

Problems solved by technology

[0005] 1. Through the setting of the fan and the blowing pipe, the device can blow the PTFE in time after the pressing plate is raised to make the cooling speed faster, but because the PTFE plate is in a semi-condensed state, If the blowing force is not well controlled, it is easy to blow and deform the surface of the board, thus affecting the overall quality

[0006] The device needs to manually pull the handle, so that the mold moves to the right along the slide bar, and the mold moves to the top of the second platen, and the electric telescopic rod shrinks, driving the pressure plate to move down, so that it is completely pressed to the top of the mold, manual manual operation It is unstable, and pulling the handle drives the mold to move, which increases the labor intensity of the operator
