[0016] A forging cleaning device, such as Figure 1 , 2As shown, it includes a mounting plate 1, on which a motor 2 is provided, on which a first pulley 3 is fixedly installed on the output shaft of the motor 2, and the output shaft of the motor 2 is coaxially arranged with the first pulley 3. Two second pulleys 5 are rotatably installed on the mounting plate 1 through two connecting rods 4, and the two second pulleys 5 are symmetrically distributed up and down. The first pulley 3 and the two second pulleys 5 are connected by a grinding belt 6 for transmission, and it is characterized in that: two first worm wheels 7 are rotatably installed on the mounting plate 1, and the two first worm wheels 7 are symmetrically distributed up and down, and one side of the two first worm wheels 7 is meshed with a same first worm 8, and the threads of the upper and lower ends of the first worm 8 have opposite rotation directions, and the first worm 8 is rotatably installed on the mounting plate 1 through a shaft seat, and support rods 9 are respectively fixedly installed on the first worm wheel 7. The utility model has a simple structure and an ingenious design. When the surface of a larger forging needs to be cleaned, the forging is placed at a designated position, two support rods 9 are grasped with both hands, and the cleaning device is picked up to grind the surface of the forging; when a lighter forging needs to be polished, the cleaning device is supported on the ground, the forging is picked up, and the forging is fit with the sanding belt 6, thereby grinding the forging. This utility model can meet market demand and is suitable for promotion. When using the utility model, when cleaning a forging of a larger size, the forging is placed at a designated position, two hands grasp the two support rods 9, the cleaning device is picked up, the motor 2 is started, the output shaft of the motor 2 rotates to drive the first pulley 3 to rotate, the first pulley 3 drives the two second pulleys 5 to rotate through the sanding belt 6, under the rotation of the first pulley 3 and the two second pulleys 5, the sanding belt 6 rotates, the cleaning device is moved to the forging, the sanding belt 6 is fitted with the surface of the forging, so that the surface of the larger forging is cleaned by the sanding belt 6; when the forging is lighter, the two support rods 9 are supported on the ground, the motor 2 is started, the output shaft of the motor 2 rotates to drive the first pulley 3 to rotate, the first pulley 3 is belted by the sanding belt 6 The two second pulleys 5 are driven to rotate. Under the rotation action of the first pulley 3 and the two second pulleys 5, the sanding belt 6 rotates to pick up the forging, so that the forging is fitted with the sanding belt 6, thereby cleaning the surface of the lighter forging; and the device can adjust the height according to the height of the user, and the first worm 8 is turned in the positive direction, and the first worm 8 drives the first worm wheel 7 on the upper side to rotate clockwise, and the first worm 8 drives the first worm wheel 7 on the lower side to rotate counterclockwise, thereby driving the upper support rod 9 to rotate clockwise, and driving the lower support rod 9 to rotate counterclockwise, and the rotation angle of the upper support rod 9 is the same as that of the lower support rod 9, at this time, the height of the cleaning device is reduced; similarly, the height of the cleaning device is increased by turning the first worm 8 in the reverse direction.

[0017] Specifically, as shown in the figure, the second worm gear 20 is fixedly installed at one end of the connecting rod 4 away from the second pulley 5 in this embodiment, and the second worm gears 20 are rotatably installed on the mounting plate 1. The same second worm 21 is meshed and matched between the two second worm gears 20, and the second worm 21 is rotatably installed on the mounting plate 1 through the shaft seat. When the second worm 21 is screwed forward, the second worm 21 drives the upper second worm gear 20 to rotate clockwise, and the second worm 21 drives the lower second worm gear 20 to rotate counterclockwise, thereby driving the upper connecting rod 4 and the upper second pulley 5 to rotate clockwise around the axis of the upper second worm gear 20, and driving the lower connecting rod 4 and the lower second pulley 5 to rotate counterclockwise around the axis of the lower second worm gear 20, and the sanding belt 6 becomes loose, at which time the sanding belt 6 can be moved between the first pulley 3 and the two second belt pulleys. The outer periphery of the wheel 5 is removed, and then the sanding belt 6 with different coarseness is replaced; the replaced sanding belt 6 is set on the outer periphery of the first pulley 3 and the two second pulleys 5, and then the second worm 21 is reversely screwed until the first pulley 3 and the two second pulleys 5 tighten the sanding belt 6. Replacing the sanding belt 6 with different coarseness is convenient for cleaning the forgings. First, use the coarse sanding belt 6 to roughly grind the forgings, and then use the fine sanding belt 6 to finely grind the forgings; or use sanding belts 6 with different coarseness for grinding according to different forgings.

[0018] Specifically, as shown in the figure, in this embodiment, a slider 30 is fixedly installed on the motor 2, a slide groove 31 is provided on the mounting plate 1, the slider 30 is slidably installed in the slide groove 31, the motor 2 and the slide groove 31 are connected by a spring 32, one end of the spring 32 is fixedly connected to one side of the motor 2, and the other end of the spring 32 is fixedly connected to the inner wall of the slide groove 31. When the surface to be cleaned of the forging is a plane, the forging is fitted with the outer periphery of the sanding belt 6, and the forging is cleaned under the transmission action of the sanding belt 6; when the surface to be cleaned of the forging is an arcuate surface, the forging is pressed against the sanding belt 6 and pushed in the direction close to the sanding belt 6. Under the thrust of the forging, the sanding belt 6 between the two second pulleys 5 is bent and fits with the arcuate surface of the forging. Since the total length of the sanding belt 6 remains unchanged and the length of the sanding belt 6 between the two second pulleys 5 increases, the length of the sanding belt 6 between the first pulley 3 and the two second pulleys 5 becomes shorter, that is, the slider 30 drives the motor 2 and the first pulley 3 to move to the right along the slide groove 31, and the spring 32 is compressed. When the forging is separated from the sanding belt 6, under the elastic force of the spring 32, the slider 30, the motor 2 and the first pulley 3 move to the left and reset.

[0019] Further, as shown in the figure, in this embodiment, one end of the first worm 8 and the second worm 21 are respectively fixedly mounted with a hand wheel 40. It is more convenient and labor-saving to screw the first worm 8 and the second worm 21 through the hand wheel 40.

[0020] Further, as shown in the figure, the support rod 9 described in this embodiment is a triangular support rod. The triangular support rod is easier to grasp and is more stable when supported on the ground.

[0021] Furthermore, as shown in the figure, the triangular support rod of this embodiment is fixedly mounted with a sponge cover 60. When the triangular support rod is grasped, the sponge cover 60 can increase the comfort of grasping and prevent the triangular support rod from hurting the hand.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it.
