Multi-station vacuum annealing machine

Abstract

A multi-station vacuum annealing machine comprises a machine frame, a workbench, a plurality of vacuumizing chambers, vacuumizing mechanism, a heating mechanism and a driving mechanism, wherein the workbench is arranged on the machine frame, the multiple vacuumizing chambers are arranged on the workbench, the vacuumizing mechanisms are communicated with the vacuumizing chambers correspondingly, the heating mechanism is used for heating one or more vacuumizing chambers, and the driving mechanism is used for driving the vacuumizing chambers and the heating mechanism to move relatively. Each vacuumizing chamber comprises a base arranged on the workbench and an upper cover cap capable of being matched with the base in a sealed manner, and each base is communicated with the corresponding vacuumizing mechanism. The heating mechanism comprises a lifting module and an electromagnetic heating coil arranged at the lower end of the lifting module, and the electromagnetic heating coils are locatedright above the one or more vacuumizing chambers. According to the multi-station vacuum annealing machine, a workpiece can be independently heated and annealed, so that the workpiece to be annealed is uniformly heated, and the annealing quality is improved; and circulation and uninterrupted automatic operation of heating annealing, heat preservation, cooling and heating annealing can be conducted, the production is planned, manual intervention is not needed, the production efficiency is high, the energy consumption is low, and the environment friendliness is achieved.

Description

technical field [0001] The invention relates to the field of vacuum annealing equipment, in particular to a multi-station vacuum annealing machine. Background technique [0002] Annealing mainly refers to a heat treatment process in which metal materials are exposed to high temperatures for a long period of time, and then slowly cooled. It can improve or eliminate various structural defects and residual stresses caused by steel casting, forging, rolling and welding, and prevent deformation and cracking of workpieces, especially in the stretching and forming process of stainless steel sheets; it can soften workpieces for processing Cutting and forming processing; it can refine the grain and improve the structure to improve the mechanical properties of the workpiece; it can also prepare the structure for the final heat treatment (quenching and tempering). After annealing, metal products have the advantages of smooth surface, no oxidation, no decarburization, etc. [0003] Ho...

AI Technical Summary

Problems solved by technology

[0003] However, most of the annealing equipment in the prior art is a large-scale annealing furnace with a single function and a complex structure.

The traditional annealing furnace is to put multiple workpieces to be annealed into the annealing furnace at the same time, and then heat them inside the annealing furnace, which makes the temperature in the furnace uneven and the annealing quality poor; and the traditional annealing furnace cannot be continuously produced, and the production capacity is low , high later maintenance cost, bulky, high construction costs and other disadvantages
