DETAILED DESCRIPTION

[0015] like Figure 1-3 As shown: a heat treatment hanger, comprising an annular frame 1 and a plurality of clamps 5; a connecting frame 2 is fixedly connected between the inner side walls of the annular frame 1, a lifting ring 3 is fixedly connected to the central top of the connecting frame 2, a plurality of evenly distributed grooves 4 are opened on the top of the annular frame 1, and the upper part of the clamps 5 is hung on the annular frame 1 and is located inside the grooves 4;

[0016] The clamp 5 includes a hanging tube 51, the top of which is fixedly connected with a hanging ring 52, which is located inside the groove 4, a slide groove 53 is provided inside the bottom of the hanging tube 51, a slide column 54 is slidably inserted inside the slide groove 53, and two parallel fixed plates 55 are vertically fixedly connected to the outer wall of the bottom end of the slide column 54, front and back, left and right, and the ends of the two parallel fixed plates 55 are rotatably connected with a connecting shaft 56, which passes through the ends of the two parallel fixed plates 55; the connecting shaft 56 passes through the clamp rod 57, and the connecting shaft 56 is fixedly connected to the clamp rod 57, and the clamp rod 57 extends up and down, and the clamp The top of the rod 57 is fixedly connected with a connecting shaft 2 58, which passes through the top of the clamping rod 57. The bottom outer wall of the hanging tube 51 is vertically fixedly connected to one end of the fixing plate 2 59 in the front, back, left and right directions. The other end of the fixing plate 2 59 is fixedly connected with a connecting shaft 3 510, which passes through the other end of the fixing plate 2 59. There are connecting rods 511 between both ends of the connecting shafts 2 58 and 3 510. The two ends of the connecting rod 511 are rotatably connected to the connecting shafts 2 58 and 3 510 respectively. The inner side of the bottom end of the clamping rod 57 is fixedly connected with a base frame 512, which is semi-annular.

[0017] The clamping rod 57 comprises a vertical rod 1 571, a horizontal rod 572 and a vertical rod 2 573 from top to bottom. The vertical rod 1 571, the horizontal rod 572 and the vertical rod 2 573 are an integrated structure. The connecting shaft 2 58 is fixedly connected to the upper part of the vertical rod 1 571. The bottom of the vertical rod 1 571 is fixedly connected to one end of the horizontal rod 572. The other end of the horizontal rod 572 is fixedly connected to the upper end of the vertical rod 2 573. The lower end of the vertical rod 2 573 is fixedly connected to the base frame 512. The base frame 512 is on the inner side of the lower end of the vertical rod 2 573.

[0018] The four base frames 512 are opened outward, and the workpiece to be heat treated is placed on the top of the four base frames 512. The lifting ring 2 52 is pulled upward 3, and the gravity of the workpiece itself will press down the base frame 512. Since the base frame 512 and the clamping rod 57 are fixedly connected, the clamping rod 57, the connecting rod 511 and the fixing plate 1 55 and the fixing plate 2 59 form a linkage mechanism through the connecting shaft 1 56, the connecting shaft 2 58 and the connecting shaft 3 510. When the base frame 512 is subjected to downward pressure, the vertical rod 2 573 will move inward, and the sliding column 54 will slide downward along the sliding groove 53 to clamp the workpiece. Since the four clamping rods 57 are used for clamping, workpieces of different shapes can be clamped. After the clamping is stable, the lifting ring 2 52 is placed in the groove 4 and connected to the lifting ring 1 3 through a lifting device (such as a crane). The entire heat treatment sling is lifted together with the workpiece to perform the heat treatment operation;

[0019] After the heat treatment is completed, the heat treatment sling is transported back together with the workpiece, the lifting ring 2 52 is removed from the groove 4, the four vertical rods 2 573 are spread open, and then the workpiece is taken out for the next use.
