Columnar workpiece inner hole quenching device and equipment

Abstract

The invention belongs to the technical field of machining, and discloses a columnar workpiece inner hole quenching device and equipment. The columnar workpiece inner hole quenching device comprises afixing frame, a workpiece bearing part, a workpiece heating part, a workpiece cooling part and a displacement control part, wherein the workpiece carrying part is arranged on the fixing frame, a columnar workpiece is positioned on the workpiece bearing part, and the workpiece heating part can extend into a columnar workpiece inner hole to be heated under the driving of the displacement control part. According to the columnar workpiece inner hole quenching device, local quenching can be carried out according to requirements, and the technical requirements of a workpiece can be met, and meanwhile, the energy consumption is reduced, and the working environment is safer and more comfortable; the workpiece is driven by rolling wheels to rotate while the workpiece is quenched, so that the heating and cooling of the workpiece can be guaranteed; and an angle adjusting mechanism is properly adjusted, so that the workpiece, an induction heating coil and an auxiliary cold water ring can be positioned at the angle that the spraying direction and the flow direction of cooling liquid is the most beneficial to the quenching effect of the workpiece, an operator can conveniently and flexibly control the quenching structure and the quenching uniformity of the workpiece, and the product quality is ensured.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a quenching device for the inner hole of a cylindrical workpiece and its equipment. Background technique [0002] There are many products in industrial machinery that need to be quenched to ensure performance, and quite a few products only need partial quenching to achieve their optimal performance. In the prior art, workpieces with such technical requirements usually use multi-purpose furnaces. Or well-type furnaces are processed by overall heating and quenching. However, this method not only consumes high energy consumption, but also has low production efficiency. Especially when the furnace is shut down in an emergency during the production process, it will face huge losses. The most important thing is Such an overall quenching method increases the overall hardness of the workpiece, which is not conducive to the subsequent development of other parts of the quench...

[0002] There are many products in industrial machinery that need to be quenched to ensure performance, and quite a few products only need partial quenching to achieve their optimal performance. In the prior art, workpieces with such technical requirements usually use multi-purpose furnaces. Or well-type furnaces are processed by overall heating and quenching. However, this method not only consumes high energy consumption, but also has low production efficiency. Especially when the furnace is shut down in an emergency during the production process, it will face huge losses. The most important thing is This overall quenching method increases the overall hardness of the workpiece, which is not conducive to the subsequent development of other parts of the quenching process. Moreover, because of the overall quenching, it also increases the difficulty of quality inspection for each product.
