Embodiment Construction

[0035] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0036] Assuming that the side length of the square workpiece 4 is a and the thickness is b, it also utilizes a binding device, the binding device includes a platform 9, the center of the platform 9 is provided with a platen 10 for placing the square workpiece 4, and the two sides of the platen 10 Side activity is provided with the clamping plate 11 that is used for fixing the square workpiece 4 on the platen 10 . Specifically, the splint 11 is fixed on the platform 9 through the air cylinder 12 . The upper surface of the platen 10 is provided with a groove 13 for the iron wire 1 to pass through, the groove 13 runs through the left side and the right side of the platen 10 , and the left side of the platen 10 is also provide...

Abstract

The invention belongs to the technical field of machinery, relates to a binding method for heat treatment of square workpieces, and solves such technical problems as inconvenience in storage and taking during quenching and tempering of traditional square workpieces. The edge lengths of the square workpieces are assumed as a, and the thicknesses are assumed as b; and the method comprises the following steps: (1) iron wires with lengths of 4a+3b+20 cm are prepared; and two ends of the iron wires are respectively ends A and B; (2) the iron wires are placed on the bottom surfaces of the square workpieces; (3) the ends A and the ends B of the iron wires are bent to the centers of the square workpieces; (4) the ends A and the ends B of the iron wires are respectively bent to the front sides and the back ends; (5) the ends A of the iron wires are bent by bonding with the front end surfaces and the bottom surfaces of the square workpieces; (6) suspension parts of the iron wires are twisted as rope knots 1 on the back end surfaces of the square workpieces; and (7) the ends A and the ends B of the iron wires are twisted together to form rope knots 2; and the rope knots 2 and the rope knots 1 are correspondingly formed to lantern rings. The binding method for heat treatment of the square workpieces has such advantages as convenience in taking and placement during quenching and tempering.

Description

technical field [0001] The invention belongs to the technical field of heat treatment tooling, and relates to a binding method for heat treatment of square workpieces. Background technique [0002] 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 surface of the workpiece. Give or improve the performance of the workpiece. [0003] The most common heat treatment includes annealing, normalizing, quenching, and tempering "four fires". Among them, quenching and tempering are closely related, and they are often used together, and both are indispensable. Due to the different shapes of the workpieces, how to properly place the workpieces has become a big problem when quenching and tempering the workpieces, because it ...
