Mold process with local high-frequency normalization participating in forming

Abstract

The invention discloses a mold process with local high-frequency normalization participating in forming, and relates to a forming mold in which an online high-frequency normalization forming process is used to solve the problems that an existing process cannot realize the local normalization process and a mode of performing global normalization on raw materials for an overall normalization processhas a longer tube making period and a high cost. The mold process involves a pre-forming mold, a pre-forming mold body, a high-frequency electric box, a mold external cable, a closed plug, a mold internal cable, a power connection terminal and a high-frequency red copper strip coil, wherein the closed plug is connected with the mold external cable and the mold internal cable separately, the moldexternal cable is connected with the high-frequency electric box, the mold internal cable is connected with the power connection terminal, the power connection terminal is connected with the high-frequency red copper strip coil, and the high-frequency red copper strip coil is annularly wound in a cavity of the pre-forming mold body. According to the process, high-frequency current is introduced atthe moment when a pre-forming process works to quickly heat parts, and then air cooling is performed to improve the toughness of products.

Description

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