Temperature-dependent drawing mold for metal sheet

Abstract

The invention relates to a temperature-dependent drawing mold for a metal sheet, which comprises a pressure plate, a female mold, a male mold and a temperature control system, wherein the male mold and the female mold enable a position of a part required to be heated for drawing deformation and a corresponding position of the pressure plate to be respectively provided with a heating hole and a temperature measuring hole, and a heating rod and a thermocouple sensor in the temperature control system are respectively placed in the heating hole and the temperature measuring hole; and the temperature control system comprises the heating rod, the thermocouple sensor, an outer-end electric control cabinet, a terminal computer system and a transforming cabinet, wherein the heating rod is connected with the transforming cabinet through a cable, the transforming cabinet is connected with the outer-end electric control cabinet through a cable, the thermocouple sensor is connected with the terminal computer system through a cable, and the terminal computer system is connected with the outer-end electric control cabinet through a cable. The invention has the advantages of simple structure, energy saving and consumption reduction, can accurately control the temperature of any specific point of each working part, and can realize drawing and shaping processes depending on different heating temperature modes, such as isothermal, non-isothermal or poikilothermal shaping mode.

Description

technical field [0001] The invention relates to a metal sheet warm drawing forming system, in particular to a metal sheet warm drawing device with a temperature control heating control system. Background technique [0002] When the material has poor plastic formability or high strength at room temperature, it is difficult to form at room temperature. In order to improve the formability of the material, it is usually necessary to carry out warm forming in the temperature range of 100-400 °C. After searching the literature of the prior art, it was found that the Chinese patent authorization announcement number CN1943906A, the invention name is: a magnesium alloy sheet material differential temperature drawing die, and the characteristics of the patent are described as follows: it has an upper die plate, an upper die backing plate, a die, The punch, the punch fixing plate, the backing plate of the lower die, the lower template, the top plate, the blank holder and the ejector ro...

AI Technical Summary

Problems solved by technology

[0003] The present invention aims to solve the technical problem that the existing metal plate material differential temperature drawing die consumes a lot of energy and cannot perform variable temperature forming, and provides a metal sheet material temperature drawing die with simple structure and low energy consumption. The die can be used for The circular mold structure can also be used for rectangular or other special-shaped molds, and can accurately control the temperature of the punch, die and blank holder to realize isothermal, differential temperature or variable temperature drawing forming of metal sheets
