Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment, in particular to a tooling for heat treatment of ball products. Background Art

[0002] Ball products, such as Figure 3 As shown, the center of the product is spherical and the two end surfaces are arc-shaped. The existing problem is that the product cannot stand stably. When loading the furnace, iron wire is used to tie the neck of the product and then fix it with tooling, which is time-consuming and labor-intensive. During heat treatment and quenching, the product will fall over and cause bumps and scratches. After the products fall over and stack together, they affect the circulation of the atmosphere and the cooling performance of quenching, resulting in uneven metallurgical indicators. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in order to overcome the deficiencies in the prior art, a tooling for heat treatment of ball products is provided.

[0004] The utility model solves the technical problem by adopting a technical solution: a tool for heat treatment of ball products, comprising a tool body, the tool body comprising an outer frame, a reinforcing rib located inside the outer frame and connected to the outer frame,

[0005] The reinforcing ribs are staggered to form a number of evenly distributed hexagonal gaps for inserting ball products. The ball products are in multi-point contact with the reinforcing ribs around them.

[0006] The hexagonal gaps are used to fix the products, which not only meets the furnace loading capacity but also ensures uniform spacing and a certain distance between products. The product and the tooling are in point contact, which ensures smooth atmosphere circulation during heat treatment and uniform quenching cooling.

[0007] The outer frame adopts a circular structure with a notch, and a flow hole connected with the outer frame and the reinforcing rib is arranged at the notch of the outer frame.

[0008] Furthermore, after the ball products are inserted into the hexagonal gaps, adjacent ball products do not contact each other.

[0009] Furthermore, the circulation holes are provided with three evenly distributed ones, so as to further ensure smooth atmosphere circulation and uniform quenching cooling during heat treatment.

[0010] The beneficial effects of the utility model are as follows: the product is fixed by the hexagonal gap with stable structure, and the furnace loading capacity is met while the spacing is guaranteed to be uniform and there is a certain spacing between the products; there is point contact between the product and the tooling, and the gap between the product and the tooling and the flow holes ensure smooth atmosphere circulation and uniform quenching cooling during heat treatment; the overall structure of the tooling is light and thin, easy to take, and can be used on both sides, completing self-shaping during heat treatment.
