Local precision heat treatment equipment for ultra-fine parts

Abstract

The invention relates to the technical field of heat treatment equipment, and discloses local precision heat treatment equipment for ultra-fine parts. The local precision heat treatment equipment comprises a bottom plate. A shell is fixedly connected to the upper surface of the bottom plate, a heat insulation sleeve is fixedly connected to the inner wall of the shell, a plurality of electric heating pipes are fixedly connected to the inner wall of the heat insulation sleeve, and a lining is fixedly connected to the inner wall of the heat insulation sleeve. A plurality of rectangular through holes are formed in the inner wall of the lining, and a temperature sensor is fixedly connected to the hole wall of one rectangular through hole. A controller is fixedly connected to the upper surface of the shell, and a T-shaped sliding groove is formed in the upper surface of the bottom plate. According to the local precision heat treatment equipment for the ultra-fine parts, the ultra-fine partscan be stably and uniformly heated, the heat treatment efficiency and quality of the ultra-fine parts are improved, and meanwhile the percent of pass of the local precision heat treatment equipment toheat treatment of the ultra-fine parts is increased. And the heat treatment operation convenience and safety of the ultra-fine parts are improved.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to a local precision heat treatment equipment for ultrafine miniature parts. Background technique [0002] In the production process of ultra-fine miniature parts, sometimes the problem of local heat treatment of ultra-fine miniature parts with a diameter of less than 0.3mm is encountered. For example, the pin of a special connector has a diameter of only 0.3mm and the material is in a quenched state. Due to the hardening of the pin processing and the influence of stress concentration, the root of the pin is prone to brittle fracture during use. Therefore, the method of heating with an alcohol lamp is often used in production to control the pin. The roots are locally heat treated. [0003] In the heat treatment process of the existing ultra-fine micro-parts alcohol lamp, the heat treatment temperature of the ultra-fine micro-parts fluctuates due to the flame swing,...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a local precision heat treatment equipment for ultra-fine miniature parts, which can improve the efficiency and quality of heat treatment of ultra-fine miniature parts, which can make the ultra-fine miniature parts heat stably and uniformly, and at the same time It improves the qualification rate of local precision heat treatment equipment for heat treatment of ultra-fine miniature parts, and improves the convenience and safety of ultra-fine miniature parts heat treatment operation. The heat treatment temperature of ultra-fine micro parts fluctuates up and down, the heating temperature is unstable, and the ultra-fine micro parts are heated unevenly, the heat treatment process takes a long time, and alcohol leakage is prone to occur during the operation of the alcohol lamp, which affects the ultra-fine micro parts. Safety issues in the heat treatment process of alcohol lamps
