Description

Technical Field

[0002] There is a quenching device for mining machinery parts with the publication number of CN 214655103 U. The driving motor drives the driving wheel to rotate clockwise, making the driving wheel engage with the driven wheel, thereby driving the driven wheel to rotate clockwise and further driving the lead screw to rotate. Since the wire block is threadedly connected to the lead screw, the wire block moves downward. On the contrary, when the driving wheel rotates counterclockwise, the wire block moves upward, causing the mechanical part placed on the placing plate to move up and down with the placing plate, and then quenching the mechanical part. However, when loading and unloading the mechanical part, the mechanical part needs to be carried and moved, which causes inconvenience in the use process and affects the quenching efficiency. Content of the Utility Model

The winding assembly is connected with the upper end of the baffle 38. A hoisting assembly is connected to the upper end of the suspension rod 31. The hoisting assembly is a general hoisting device, which is prior art and will not be elaborated here. The limiting shafts 35 are fixedly connected with the support frame 32 and are slidably connected with the first limiting grooves 13 and the second limiting grooves 14; the support rollers 34 are rotatably connected with the support frame 32. Support frames 41 are arranged at positions corresponding to the upper feeding port 11 and the discharging port 12 on both sides of the quenching tank 1. Conveyor rollers 42 are rotatably installed on the support frames 41. The conveyor rollers 42 are arranged at intervals, which is convenient for loading and unloading the mechanical components. The suspension rod 31 is hoisted up or down integrally through the hoisting assembly, so that the support frame 32 moves up and down relative to the quenching tank 1 as a whole, and the mechanical components on the support rollers 34 are quenched.

[0026] In this embodiment: The winding component includes a support plate 39 fixed to the lower end of the suspension rod 31. There are two support plates 39. A rotating shaft 310 is provided on the support plate 39. Between the support plates 39, two wire wheels 314 are installed on the rotating shaft 310. A worm gear 311 is installed at one end of the rotating shaft 310. A worm 312 is engaged with the worm gear 311. One end of the worm 312 is connected to a servo motor 313. Pulling ropes 315 are respectively wound on the wire wheels 314, and the winding directions of the two pulling ropes 315 are opposite. The other end of the pulling rope 315 is connected to the baffle 38. The rotating shaft 310 is rotatably connected to the support plate 39, the wire wheel 314 is fixedly connected to the rotating shaft 310, and the baffle 38 is slidably connected to the column 33. By rotating the servo motor 313, the rotating shaft 310 rotates, winding or releasing the pulling ropes 315 on the wire wheels 314, so that the baffle 38 is pulled up or dropped down, facilitating the opening and closing of the front and rear sides of the column 33.

[0027] In this embodiment: The circulation mechanism includes a liquid inlet pipe 21 and a liquid outlet pipe 22 communicated with the quenching tank 1. The liquid inlet pipe 21 is arranged at a lower position of the quenching tank 1, and the liquid outlet pipe 22 is arranged at an upper position of the quenching tank 1. Pump bodies 23 are installed on both the liquid inlet pipe 21 and the liquid outlet pipe 22. The liquid inlet pipe 21 is connected to the liquid outlet end of the pump body 23, and the liquid outlet pipe 22 is connected to the liquid inlet end of the pump body 23. The other ends of the liquid inlet pipe 21 and the liquid outlet pipe 22 are communicated with the quenching liquid cooling tank. By the operation of the pump body 23, the quenching liquid in the quenching tank 1 and the quenching liquid in the quenching liquid cooling tank are circulated, improving the cooling effect of the quenching liquid.

[0028] Working principle and usage process of the utility model: The hanging rod 31 is lifted upward integrally by the hoisting assembly, so that the supporting rollers 34 on the supporting frame 32 are flush with the conveying rollers 42. The worm 312 is driven to rotate by the servo motor 313. The worm 312 meshes with the worm gear 311 to drive the rotating shaft 310 to rotate, so that the wire wheel 314 on the rotating shaft 310 winds the pulling rope 315, pulling the baffle 38 to move upward in the chute of the column 33, and pushing the mechanical components supported by the conveying rollers 42 onto the supporting rollers 34. The servo motor 313 is rotated in the reverse direction to reverse the rotation of the rotating shaft 310, and the pulling rope 315 on the wire wheel 314 is released. The baffle 38 moves downward to block the front and rear sides of the column 33. Then, the hoisting assembly drops the whole into the quenching liquid in the quenching tank 1. The pump body 23 on the liquid inlet pipe 21 and the liquid outlet pipe 22 works, so that the quenching liquid in the quenching tank 1 circulates with the quenching liquid in the quenching liquid cooling tank. After quenching, the hanging rod 31 is lifted upward. The limiting shafts 35 on both sides of the supporting frame 32 slide upward under the limitation of the first limiting groove 13 and the second limiting groove 14. At the same time, the servo motor 313 works to pull the baffle 38 upward. When the limiting shaft 35 moves to the upper end of the first limiting groove 13 and the hanging rod 31 continues to be lifted upward, the limiting shaft 35 in the second limiting groove 14 rotates upward around the limiting shaft 35 in the first limiting groove 13, so that the mechanical components on the supporting rollers 34 slide onto the conveying rollers 42 at the material outlet 12. Then, when the hanging rod 31 is placed downward, the limiting shafts 35 on both sides of the supporting frame 32 first rotate to the horizontal state under the limitation of the first limiting groove 13 and the second limiting groove 14, and then the next quenching is carried out.

Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the utility model claimed.
