Description

Technical Field

[0001] The present invention relates to the technical field of heat treatment devices, in particular to a heat treatment device for an automobile flange shaft. Background Art

[0002] Metal heat treatment is a key process in mechanical manufacturing. Compared to other machining processes, heat treatment generally does not alter the workpiece's shape or overall chemical composition. Instead, it modifies the workpiece's internal microstructure or surface chemical composition to impart or improve its performance. Its hallmark is improvement in the workpiece's intrinsic quality, which is generally invisible to the naked eye. To achieve the desired mechanical, physical, and chemical properties in a metal workpiece, heat treatment is often essential, in addition to the appropriate selection of materials and various forming processes. Steel is the most widely used material in the machinery industry. Its complex microstructure can be controlled through heat treatment, making heat treatment of steel a primary component of metal heat treatment. Additionally, aluminum, copper, magnesium, titanium, and their alloys can also be heat treated to modify their mechanical, physical, and chemical properties to achieve varying performance characteristics.

[0030] In this embodiment, the transmission assembly includes two pulleys 16 fixedly mounted on the outer surfaces of the rotating shaft 6 and the transmission rod 18 respectively. The outer surfaces of the two pulleys 16 are covered with belts 17.

[0031] In this embodiment, the height adjustment mechanism includes a screw rod 22 fixedly mounted on the upper surface of the movable plate 11, a rectangular groove 23 is opened through the outer surface of the fixed plate 9, a slider 24 is slidably mounted on the inner wall of the rectangular groove 23, the slider 24 is a cross-shaped structure, and a rotating wheel 26 is rotatably mounted on the upper surface of the slider 24. The top end of the screw rod 22 passes through the upper surface of the slider 24 and the rotating wheel 26, and the screw rod 22 is threadedly connected to the rotating wheel 26.

[0032] In this embodiment, two C-shaped limit plates 25 corresponding to the length direction of the rectangular groove 23 are symmetrically fixedly installed on the upper surface of the fixed plate 9, and the opposite sides of the slider 24 are slidably installed on the outer surface of the C-shaped limit plates 25. The C-shaped limit plates 25 are used to limit and support the slider 24.

[0033] In this embodiment, a T-shaped groove 21 is provided on the lower surface of the fixed plate 9, and a T-shaped slider 20 matching the T-shaped groove 21 is fixedly installed on the upper surface of the C-shaped plate 10.

[0037] While the rotating shaft 6 drives the turntable 5 to rotate, the rotating shaft 6 will drive the transmission rod 18 to rotate through the pulley 16 and the belt 17, so that the cam 19 installed on the top of the transmission rod 18 rotates, so that the cam 19 continuously pushes the inner walls of the opposite sides of the C-shaped push plate 14, so that the C-shaped push plate 14 drives the C-shaped plate 10 to move back and forth along the T-shaped slide 21 through the guide rod 13, so that the moving plate 11 installed on the C-shaped plate 10 drives the multiple high-pressure flame nozzles 12 to swing back and forth, so as to avoid the gap between two adjacent high-pressure flame nozzles 12 being too large, so that the temperature at the gap is low, and the flange shaft placed on the turntable 5 cannot be evenly heated.

[0038] When heat treating flange shafts of different lengths, before heat treatment, the runner 26 is rotated so that the runner 26 drives the movable plate 11 to move up and down through the screw rod 22 threadedly connected thereto, thereby adjusting the height of the multiple high-pressure flame nozzles 12 installed on the lower surface of the movable plate 11 to perform heat treatment operations on flange shafts of different lengths.
