A mold process with local high-frequency normalizing involved in forming

Abstract

A mold process in which local high-frequency normalizing participates in forming relates to an online high-frequency normalizing forming process used in a forming mold, which solves the problem that the existing process cannot realize the local normalizing process, and adopts global normalizing on raw materials. The overall normalizing process is carried out by means of the method, which has the problems of prolonged tube-making cycle and high cost, including pre-formed mold, pre-formed mold body, high-frequency electric box, mold external cable, closed plug, mold internal cable, power connection terminal and high-frequency electric box. Copper strip coil; the closed plug is connected to the external cable of the mold and the internal cable of the mold, the external cable of the mold is connected to the high-frequency electric box, the internal cable of the mold is connected to the power terminal, and the terminal is connected to the high-frequency copper strip coil; high-frequency copper strip The coil is annularly wound in the cavity of the preformed mold body. In the process of the invention, a high-frequency current is applied at the moment when the pre-forming process is working, and the parts are rapidly heated, and then air-cooled to improve the toughness of the product.

Description

technical field [0001] The invention relates to an online high-frequency normalizing forming process used in a forming mold. Specifically, it relates to a mold process in which local high-frequency normalizing participates in forming. Background technique [0002] In the production of internal high pressure forming molds or cold stamping plastic molds, product defects such as difficulty in product shape forming and local cracking are often encountered, resulting in increased debugging time, high part scrap rate, and limited parts forming. In the pipe bending process of the traditional process of high pressure forming parts, the raw material is a straight pipe, and the straight pipe is bent into a part that can be used in the pre-forming process through a pipe bending die. In the pre-forming process step, the shape of the elbow part is pressed into a part conforming to the internal high pressure forming process by stamping. In the internal high pressure forming process step...
