Embodiment Construction

[0039] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0040]The embodiment of the present invention provides a three-stage heating process for forging blanks, which can accurately control the temperature of metal blanks (that is, forging blanks). The heating equipment for implementing the process method specifically includes three parts: a preheating section and a heating section. and heat preservation section, and the preheating section, heating section and heat preservation section are arranged in an integral structure, that is, the three sections can be integrated, but each section has different functions, or the three sections are connected in sequence, such as seamless connection, etc.; to be heated The metal blank...

Abstract

The invention provides a forged blank three-stage type heating process method. The method comprises the steps that a to-be-heated metal blank is pushed into a preheating section, and the surface temperature of the metal blank in the preheating section is detected in real time; when the surface temperature of the metal blank in the preheating section is higher than a first preset temperature value,the metal blank is pushed into a heating section, and the surface temperature of the metal blank in the heating section is detected in real time; when the surface temperature of the metal blank in the heating section is higher than a second preset temperature value, the metal blank is pushed into a heat insulation section; the second preset temperature value is higher than the first preset temperature value, and the difference value between the heat insulation temperature of the heat insulation section and the heating temperature of the heating section is lower than a preset difference value;and after the metal blank is subjected to heat insulation for a preset time in the heat insulation section, the metal blank is pushed into a stamping device to be stamped. Through the method, the inside and outside temperature distributions of the metal blank tend to be uniform, and thus the temperature of the metal blank is more in line with the process requirement.

Description

technical field [0001] The invention relates to the technical field of heating technology, in particular to a three-stage heating method for forging blanks. Background technique [0002] At present, metal blanks are often obtained by stamping, and stamping requires materials to have good mechanical strength and plasticity at room temperature, so hot stamping (such as red punching process, etc.) is generally used, including heating process and stamping process. The metal material is heated in the heating furnace, and then the heated metal material is placed in a hot extrusion die (such as a red punch die), and the pressure of the press is used to force the metal material to be extruded into the die cavity through complex flow Shaped complex metal blanks. [0003] The heating process before metal blank forming is a very important step. Traditional thermoforming generally has two methods: flame heating and electric heating. Due to the different temperatures of the outer flame...
