A reinforcing plate 5 is connected between the upper parts of the two n-shaped frames 4, and a lifting plate 6 is provided between the two n-shaped frames 4. Side plates 7 are connected to both sides of the lifting plate 6, and two guide wheels 8 are connected to one side of each of the two side plates 7. The two guide wheels 8 on both sides are distributed vertically, and the two guide wheels 8 respectively interact with the inner surfaces of the n-shaped frames 4. The two side walls roll into contact. A boss 9 is connected to the middle of one side of the lifting plate 6. A first U-shaped seat 10 is connected to the upper end of the boss 9. A fixed platform 11 is connected to the middle of the upper end of the base frame 1. A cylinder 12 is connected to the upper end of the fixed platform 11.

The rope 16 passes around the pulley 14 and connects to the first U-shaped seat 10.

[0022] A horizontal bar 18 is connected to one side of the lifting plate 6 via a connecting rod 17. A hanging rod 19 is movably hung at the upper end of the horizontal bar 18, and a receiving groove 20 is connected to the lower end of the hanging rod 19. The receiving groove 20 can be raised and lowered and placed inside the cooling assembly 3.

[0023] The cooling assembly 3 includes a cooling tank 301 located at the upper end of the tray 2. An L-shaped plate 302 is connected to the lower end of the interior of the cooling tank 301. A sedimentation zone 303 is formed between one side of the L-shaped plate 302 and the inner wall of the cooling tank 301. Two drain pipes 304 are connected to the outer wall of the cooling tank 301 and one side of the sedimentation zone 303.

[0024] A driven roller 305 and a driving roller 306 are rotatably connected to the lower side of the interior of the cooling tank 301. One end of the driving roller 306 extends to the outer wall of the cooling tank 301 and is connected to a motor 307. An adjusting roller 308 is provided above the driven roller 305. A transmission belt 309 is sleeved on the outside of the driving roller 306, the driven roller 305 and the adjusting roller 308. A flexible scraper 310 is provided on the outside of the transmission belt 309. The flexible scraper 310 on the lower end face of the transmission belt 309 contacts the upper end face of the L-shaped plate 302. A limiting roller 311 is provided on the upper end of the transmission belt 309 near the driven roller 305.

[0025] A fixing block 312 is symmetrically connected to one side of the upper end of the cooling tank 301. The upper ends of the two fixing blocks 312 are threadedly connected to screws 313. The upper ends of the two screws 313 are connected to handles 314. The lower ends of the two screws 313 are rotatably connected to support plates 315. The two support plates 315 are rotatably sleeved with the shaft ends on both sides of the adjusting roller 308.

[0026] By rotating the handle 314, the screw 313 is driven to rotate, which in turn causes the screw 313 to move up and down, thereby driving the adjusting roller 308 between the two support plates 315 to move up and down, thus adjusting the tension of the entire transmission belt 309.

[0027] A U-shaped protective frame 21 is connected to one side of each of the two n-shaped frames 4.

[0028] Working principle:

[0029] Precision parts that need to be quenched are placed in the receiving tank 20. The design of the receiving tank 20 facilitates the placement and removal of parts, and its bottom is mesh-like to facilitate the penetration of coolant and the falling of metal chips.

[0030] The receiving slot 20 is suspended on the crossbar 18 by the hanging rod 19. The crossbar 18 is connected to the lifting plate 6 by the connecting rod 17, forming a lifting suspension system.

[0031] The extension and retraction of cylinder 12 is used to control the lifting and lowering of parts for cooling and removal. The output end of cylinder 12 is connected to support rod 13, and pulley 14 is mounted on the upper end of support rod 13.

[0032] One end of the rope 16 is connected to the second U-shaped seat 15, and the other end passes around the pulley 14 and is connected to the first U-shaped seat 10. When the cylinder 12 extends or retracts, the first U-shaped seat 10 and the lifting plate 6 connected thereto are driven to move up and down through the transmission of the pulley 14 and the rope 16.

[0033] The lifting plate 6, under the action of the guide wheels 8 on both sides, maintains vertical lifting and lowering to ensure the smooth lifting and lowering of the parts;

[0034] When the lifting plate 6 descends to the set low position, the receiving tank 20 and the parts therein are completely immersed in the coolant in the cooling tank 301 to achieve quenching and cooling of the parts.

[0035] During the quenching process of the parts, metal chips will flow into the bottom of the cooling tank 301 with the coolant. Since the bottom of the receiving tank 20 is mesh-like, the chips can fall off smoothly.

[0036] The lower side of the interior of the cooling tank 301 is provided with a driven roller 305, a driving roller 306 and an adjusting roller 308, and a transmission belt 309 is sleeved on the outside. A flexible scraper 310 is mounted on the surface of the transmission belt 309 to scrape metal debris from the coolant.

[0037] The motor 307 drives the active roller 306 to rotate, which in turn drives the transmission belt 309 and the flexible scraper 310 to move between the active roller 306, the driven roller 305 and the adjusting roller 308.

[0038] The limiting roller 311 is used to limit the transmission belt 309 from the top, so that the entire transmission belt 309 is in an L-shape; in this way, the flexible scraper 310 can scrape the metal debris in the coolant downward to the upper surface of the L-shaped plate 302 during the transmission process.

[0039] A sedimentation zone 303 is formed between one side of the L-shaped plate 302 and the inner wall of the cooling tank 301. Metal scraps are eventually collected in the sedimentation zone 303 by the scraping and conveying of the flexible scraper 310.

[0040] The bottom of the sedimentation zone 303 is connected to two drain pipes 304, which facilitates the periodic discharge of collected metal debris and keeps the coolant clean.
