Description

Technical Field

[0001] This utility model relates to the field of track plate technology, and specifically to a heat treatment device for track plates. Background Technology

[0002] Track shoes are key components of the running gear of construction machinery, agricultural machinery and heavy vehicles. To meet the performance requirements of track shoes, the forged or cast track shoes usually need to be heat treated, and the process mainly includes quenching and tempering.

[0003] Existing technologies have made many improvements to track plate heat treatment devices. For example, Chinese patent CN218580011U discloses a high-efficiency heat treatment device for track plates, including a base. The top of the base is fixedly connected to the heat treatment device body, and the bottom of the heat treatment device body is rotatably connected to a conveyor belt. The inner wall of the conveyor belt is rotatably connected to a drive roller, the front of the drive roller is fixedly connected to a motor, the outer wall of the drive roller is rotatably connected to a belt, and the inner wall of the conveyor belt is rotatably connected to a driven roller. The drive roller and the driven roller drive the conveyor belt, which in turn drives the track plate body. A heater body is set up so that when the track plate body passes through the heater body, it undergoes high-efficiency heat treatment, thereby achieving high-efficiency heat treatment of the track plate and improving the working efficiency of the heat treatment device body.

[0004] However, the following problems still exist in practical applications: 1. Cooling the heated track plates wastes a lot of water, increasing the operating cost of the device and making it less practical. 2. During the cooling process, the track plates are prone to warping and other damage. There is no repair mechanism for such damage, which affects the overall quality of the product.

[0033] In this invention, the track plate workpiece 6 is placed on the first roller conveyor line 11, such that the gap between the second extension plate 63 and the third extension plate 64 is located above the positioning guide ring 5. When the track plate workpiece 6 moves below the heating furnace 2, the first roller conveyor line 11 stops moving, and the lifting double-rod cylinder 33 on the cylinder connecting plate 34 is activated, pushing the lifting column 31 and the lifting connecting plate 32 upward, thereby pushing the track plate workpiece 6 upward and reducing the contact area of ​​the track plate workpiece 6 so that the track plate workpiece 6 is heated evenly. After the track plate workpiece 6 is heated, the lifting double-rod cylinder 33 is activated, the lifting column 31 and the lifting connecting plate 32 are reset, and the track plate workpiece 6 continues to be transported to the right along the first roller conveyor line 11. The track plate workpiece 6 is moved to the second roller conveyor line 12. When part 6 reaches below the pressure cooling plate 403, the second roller conveyor line 12 stops moving. At this time, the pressure double-rod cylinder 408 is activated. With the cooperation of the pressure connecting plate 407, the pressure limiting plate 405, and the water pipe clearance hole 406, the pressure cooling plate 403 is brought into contact with the upper end of the track plate part 6. At the same time, the water pump on the cooling water inlet pipe 409 is activated, so that external cooling water is sprayed out from the cooling nozzle 410 along the cooling water inlet pipe 409. The cooling water is sprayed downward through the cooling hole 404 to cool and shape the track plate part 6. When the track plate part 6 is cooled, the pressure double-rod cylinder 408 is activated, which drives the water pipe clearance hole 406 and the pressure connecting plate 407 to reset. At this time, the second roller conveyor line 12 is activated, and the track plate part 6 is transferred to the third roller conveyor line 13 for the next process.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
