Its main purpose is to adjust and improve its organizational structure and performance by controlling the heating, insulation and cooling process of steel, so as to achieve the purpose of improving hardness, strength, wear resistance and corrosion resistance. The hoists for entering and exiting the furnace are to ensure the safe and effective transportation of mold steel during the heat treatment process, and to ensure the quality and stability of the mold.

[0003] Traditional mold steel heat treatment furnace hoists are usually made of high-temperature alloy steel, which can maintain stability and strength at high temperatures. They are made of chains with high-temperature resistant hooks or clamps to safely hang and move the mold steel. They can also effectively protect the mold steel and improve production efficiency.

[0004] Traditional hangers for mold steel heat treatment in and out of the furnace are usually fixed-shape hooks or clamps to fix the mold steel, which cannot clamp mold steel of different thicknesses. If mold steel of different thicknesses needs to be transported, the hangers or clamps must be replaced, which increases costs or affects work efficiency. Therefore, a hanger for mold steel heat treatment in and out of the furnace is proposed to solve the above problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1-Figure 2The utility model provides an embodiment: a hanger for heat treatment of mold steel in and out of a furnace, comprising a load-bearing frame 1, a support frame 2 is arranged at the bottom of the load-bearing frame 1, a side wall of the support frame 2 is fixedly connected with a fixing ring 3, a side wall of the fixing ring 3 is rotatably connected with a fixing seat 4, a screw 6 is rotatably connected inside the fixing seat 4, one end of the screw 6 is fixedly connected with a knob 7, and the other end of the screw 6 is fixedly connected with a limiting block 8, a side wall of the fixing ring 3 is rotatably connected with a swivel 9, a side wall of the swivel 9 is rotatably connected with a slider 5, the slider 5 is internally threadedly connected to the side wall of the screw 6, a limiting groove 10 is provided inside the swivel 9, a side wall of the fixing ring 3 is fixedly connected with a fixing column 11, a side wall of the fixing column 11 is rotatably connected with a rack 14, a side wall of the rack 14 is slidably connected with a limiting ring 12, a side wall of the limiting ring 12 is fixedly connected with a fixing block 13, and a side wall of the fixing block 13 is rotatably connected inside the swivel 9.

[0032] In order to ensure that the mold steel can be properly fixed, it is necessary to adjust the distance between the racks 14 according to the specific diameter of the mold steel. First, it is necessary to turn the knob 7 to drive the screw 6 to rotate. As the screw 6 rotates, the slider 5 located on its side wall will be driven, and then the swivel 9 will start to rotate. The rotation effect of the swivel 9 causes the limit ring 12 to slide on the side wall of the rack 14, so that the opening and deflection of the rack 14 can be accurately controlled. When the rack 14 successfully clamps the outer wall of the mold steel, it means that the fixing work has been completed. At this time, it is necessary to stop rotating the knob 7, so that the mold steel is fixed inside the fixing ring 3. At this point, the fixation of the mold steel is completely completed.

[0033] Reference Figure 3 A sliding groove 15 is provided inside the load-bearing frame 1, and a screw rod 16 is rotatably connected inside the load-bearing frame 1. The screw rod 16 is arranged inside the sliding groove 15, and one end of the screw rod 16 is fixedly connected to an auxiliary component, and the auxiliary component is used to rotate the screw rod 16. The side wall of the screw rod 16 is threadedly connected to a movable block 18. The upper surface of the support frame 2 is fixedly connected to the lower surface of the movable block 18, and the side wall of the movable block 18 is fixedly connected to a limited block 19. A limited groove 20 is provided inside the sliding groove 15, and the side wall of the limited block 19 is slidably connected inside the limited groove 20, and the side wall of the movable block 18 is slidably connected inside the sliding groove 15. A lifting ring 21 is fixedly connected to the upper surface of the load-bearing frame 1, and the lifting ring 21 is arranged in a rectangular array. Iron chains 22 are arranged inside the lifting ring 21. A horizontal hanger 24 is arranged on the top of the load-bearing frame 1, and a lifting ring 23 is fixedly connected to the lower surface of the horizontal hanger 24. One end of the iron chain 22 is arranged inside the lifting ring 23, and the lifting ring 23 is connected to the lifting ring 21 through the iron chain 22. A hanging ring 25 is fixedly connected to the side wall of the horizontal hanger 24, and the hanging ring 25 is arranged directly above the load-bearing frame 1. The auxiliary component includes a handle 17, and the side wall of the handle 17 is fixedly connected to one end of the screw 2 16, and the handle 17 is rotatably connected to the inside of the load-bearing frame 1.

[0034] When using this equipment to carry out heat treatment of mold steel in and out of the furnace, it is first necessary to adjust the distance between the support frames 2 in order to achieve the predetermined effect. The handle 17 needs to be turned, which can drive the screw rod 16 to rotate. The rotation of the screw rod 16 will cause the movable block 18 to start moving inside the sliding groove 15. The movement of the movable block 18 will also drive the limit block 19 to slide inside the limit groove 20. This can ensure the stability of the movable block 18 so that it will not shake or become unstable during movement. When the appropriate spacing is adjusted, the handle 17 needs to be stopped from rotating. At this time, the adjustment of the spacing between the fixed rings 3 is completed.

[0035] Working principle: When using this equipment to heat treat the mold steel in and out of the furnace, first adjust the distance between the support frame 2, and by turning the handle 17, drive the screw rod 16 to rotate, and the screw rod 16 drives the movable block 18 to move inside the sliding groove 15, and the movable block 18 drives the limit block 19 to slide inside the limit groove 20, ensuring the stability of the movable block 18. When the appropriate spacing is adjusted, stop rotating the handle 17, and the spacing between the fixed rings 3 is adjusted. At this time, according to the diameter of the mold steel, adjust the spacing between the racks 14, turn the knob 7 to drive the screw rod 16 to rotate, so that the slider 5 slides on the side wall of the screw rod 16, thereby driving the rotating ring 9 to rotate, and the rotating ring 9 drives the limit ring 12 to slide on the side wall of the rack 14 to control the opening and deflection of the rack 14. When the rack 14 clamps the outer wall of the mold steel, stop rotating the knob 7 to fix the mold steel inside the fixed ring 3, thereby completing the fixation of the mold steel.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
