Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment tooling, in particular to a heat treatment tooling for flatness shaping of special-shaped flat disks. Background Art

[0002] Heat treatment, a key step in improving material properties, enhancing hardness, and wear resistance, plays a crucial role in the production of flat discs. However, complex, non-standard disc shapes are often encountered during heat treatment. Due to their unconventional geometries, these products are prone to significant flat deformation after heat treatment. This deformation not only exceeds the design tolerance, severely affecting product assembly accuracy and performance, but also increases the difficulty and cost of subsequent processing, becoming a bottleneck restricting production efficiency and quality improvements.

[0003] The traditional solution to this challenge is to design a set of shaping tools for each product to ensure that its size and shape meet the design requirements. However, this approach is not only time-consuming and labor-intensive, increasing manufacturing costs, but also hindering the flexibility and versatility of the production line.

[0004] Therefore, in order to effectively control the plane deformation caused by heat treatment and at the same time achieve cost control and maximize production efficiency, it is necessary to propose an all-in-one shaping tool that can be applied to a variety of disc products with different shapes.

[0035] The threaded rod 3 passes through the opening of the lower mold 2 and then through the opening of the special-shaped flat plate, and then through the opening of the upper mold 1 to fix the special-shaped flat plate between the upper mold 1 and the lower mold 2. The end of the threaded rod 3 close to the lower mold 2 is provided with a screw head 31.

[0038] A set of lifting ring holes 14 are provided on the upper mold 1 to facilitate the lifting of the tooling into the furnace for heat treatment.

[0039] like Figure 7 and Figure 8 As shown, the special-shaped planar disk includes a first planar disk 4 with a first opening 41 and a second planar disk 5 with a second opening 51;

[0040] The first set of threaded rods 3 pass through the lower left hole 21 of the lower mold 2, then through the first openings 41 of the n first flat plates 4 or the second openings 51 of the m second flat plates 5, and then through the upper left hole 11 of the upper mold 1;
