A binding method and auxiliary binding device for heat treatment of disc-shaped workpieces

Abstract

The invention belongs to the technical field of machines, and relates to a bundling method and an auxiliary bundling device for disc-shaped workpiece heat treatment. The bundling method and the auxiliary bundling device solve the problems that existing disc-shaped workpieces are not convenient to bundle, and heat treatment is difficult. The bundling method comprises the following steps that firstly, two iron wires the same in length are taken and well twisted to be placed at the bottom of a disc-shaped workpiece to form an iron wire set; secondly, the horizontally-placed iron wire set is bent in the vertical direction; thirdly, a section A and a section C of the iron wire set are bent towards the rear end and twisted into a first rope knot, a section B and a section D are bent towards the front end and twisted into a second rope knot; fourthly, the section A, the section B, the section C and the section D of the iron wires are bent towards the top of the peripheral face of the disc-shaped workpiece; and fifthly, the section A, the section B, the section C and the section D of the iron wire set are twisted into a third rope knot at the top end of the peripheral face of the disc-shaped workpiece, the end portions of the section A, the section B, the section C and the section D of the iron wire set are twisted into a fourth rope knot, and a lantern ring is formed by the third rope knot and the fourth rope knot. The bundling method and the auxiliary bundling device can effectively solve the problem about bundling of the disc-shaped workpiece, and accordingly the disc-shaped workpiece can be conveniently placed in a salt bath furnace.

Description

technical field [0001] The invention belongs to the technical field of heat treatment tooling, and relates to a binding method and an auxiliary binding device for heat treatment of disc-shaped workpieces. Background technique [0002] Metal heat treatment is one of the important processes in mechanical manufacturing. Compared with other processing techniques, heat treatment generally does not change the shape and overall chemical composition of the workpiece, but changes the microstructure inside the workpiece or changes the chemical composition of the workpiece surface. , to give or improve the performance of the workpiece. Annealing, normalizing, quenching, and tempering are the "four fires" in the overall heat treatment. Among them, quenching and tempering are closely related, and they are often used together, and both are indispensable. Quenching is to rapidly cool the workpiece in quenching media such as water, oil or other inorganic salts and organic aqueous solutions...
