[0029] Figures 1 to 7 The one shown is a heat treatment tooling for flatness shaping of curling disks, comprising a lower mold 1, a threaded rod 4 and an upper mold 8. Four mounting holes 3 with keyways 2 are evenly opened on the lower mold 1. The mounting holes 3 are countersunk holes, and threaded rods 4 are installed in the mounting holes 3. The threaded rods 4 are perpendicular to the lower mold 1, and the lower end of the threaded rod 4 has a spline 5 that cooperates with the keyway 2; the keyway 2 and the spline 5 cooperate to prevent the threaded rod 4 from rotating.

[0030] Multiple layers of curled disc products 7 are placed on the lower mold 1 from bottom to top, and a pad 6 is placed between two adjacent curled disc products 7. The pad 6 has a certain thickness, and the thickness depends on the curling amplitude of the curled disc products. The purpose of placing the pad 6 is to prevent the two adjacent curled disc products 7 from colliding with each other and affecting the product quality.

[0031] An upper mold 8 is placed above the top layer of curled disc products 7. The upper mold 8 has a through hole 9 that matches the position of the mounting hole 3 on the lower mold 1. The upper section of the threaded rod 4 passes through the through hole 9 and is threadedly connected to the nut. The upper mold 8 can be loosened by screwing or tightening the nut, or the multi-layer curled disc products 7 below can be pressed by pressing the upper mold 8.

[0032] Since the curled disc product 7 has a curled edge, when the curled edge of the curled disc product 7 is placed upward, a barrier block is provided between the topmost layer of the curled disc product 7 and the bottom of the upper mold 8 to prevent the bottom of the upper mold 8 from contacting the curled edge, or when the curled edge of the curled disc product 7 is placed downward, a barrier block is provided between the bottommost layer of the curled disc product 7 and the top of the lower mold 1 to prevent the top of the lower mold 1 from contacting the curled edge. In order to reduce costs, the barrier block is formed by stacking multiple pads 6, and the figure shows three pads 6 stacked together. In order to prevent or reduce the problem of large deformation of the center plane of the curled disc product 7, the size of the pad 6 is consistent with the size of the center plane of the curled disc product 7, and the pad 6 also has a hole that matches the threaded rod 4.

[0033] The curled disc product 7 is an existing product. The disc body of the curled disc product 7 has a through hole or through groove 10, and the threaded rod 4 is arranged through the through hole or through groove 10. The threaded rod 4 also uses a threaded rod with a smooth section 13 in the lower half of the rod body and a threaded section 14 in the upper half of the rod body.

[0034] In order to facilitate lifting, a plurality of lifting rings 11 are installed on the upper mold 8, and the lifting rings 11 are installed through the lifting holes 17.

[0035] In order to reduce deformation of the lower mold 1 and the upper mold 8 and increase their service life, a circular hole 12 is opened at the center of the lower mold 1 and the upper mold 8.

[0036] When used specifically

[0037] S1: Unscrew the nut and lift the upper mold 8 through the lifting ring 11;

[0038] S2: A backing plate 6 is placed on top of the lower mold 1, and a curled disc product 7 is placed on the backing plate 6, with the curled edge of the curled disc product 7 facing upwards;
