Description

Technical Field

[0001] The present invention relates to the technical field of metal grinding, and particularly relates to a planar wire drawing device. Background Art

[0002] In product manufacturing, welding is commonly used to connect objects. After the objects are welded and connected, the surface will have protrusions caused by welding. The protruding parts need to be polished by equipment to make the surface of the objects flat. At the same time, the surface of the objects may have a rust layer, which also needs to be polished so that the surface is smooth before painting. When the existing objects are polished, generally, a circular grinding disc is used to polish the surface. During the polishing process, the grinding disc needs to be continuously moved to adjust the polishing angle. Otherwise, over-polishing may cause grinding grooves, and the control degree of polishing is difficult to control. When dealing with steps, the polishing difficulty is relatively large, and it is difficult to meet the existing polishing degree. Summary of the Invention

An annular grinding belt is connected between the two rollers. A pressing assembly that can slide between the two rollers is arranged in the middle of the frame body. The pressing assembly is located inside the grinding belt and pushes the grinding belt to polish the object.

[0005] Preferably, two sets of parallel sub-guide rails facing the two rollers are arranged inside the frame body, and the pressing assembly slides corresponding to the two sub-guide rails and changes the distance from the rollers.

DETAILED DESCRIPTION OF THE INVENTION

[0020] Embodiment

[0021] Please refer to Figures 1 - 5, the present invention provides a planar wire drawing device, which includes a guide rail 1 laid on the ground and a frame 2 that slides relative to the guide rail 1. Two rollers 3 are rotatably installed at both ends of the frame 2. One of the rollers 3 is driven by a driving mechanism 7 installed on the frame 2. An annular grinding belt 5 is connected between the two rollers 3. A pressing assembly 4 that can slide between the two rollers 3 is arranged in the middle of the frame 2. The pressing assembly 4 is located inside the grinding belt 5 and pushes the grinding belt 5 to grind an object; in this solution, the object is placed below the grinding belt 5. The grinding belt 5 will run as the rollers 3 rotate. A pressing assembly 4 is arranged inside the circle of the grinding belt 5. The pressing assembly 4 can press the object in contact with the lower part of the grinding belt 5 and grind the object. One of the two rollers in this solution is connected to the driving mechanism 7 for driving. The shaft body 31 of the other roller 3 can slide horizontally relative to the frame 2, which can cope with the operation of the pressing assembly 4 and change the slackness of the grinding belt. The pressing assembly 4 can move relative to the frame 2 and move towards one of the rollers 3, which can change the position of the pressing assembly 4 and grind the surface of the object.

[0022] In the specific implementation manner, referring to Figure 2 , Figure 3 , two sets of parallel sub-guide rails 211 facing the two rollers 3 are arranged inside the frame 2. The pressing assembly 4 slides corresponding to the two sub-guide rails 211 and changes the distance from the rollers 3; in this solution, the horizontal movement of the frame 2 is guided by the sub-guide rails 211. The sub-guide rails 211 are left-right guides in this solution and are installed up and down. The pressing assembly 4 can move left and right along the sub-guide rails 211 and adjust the pressing position, so as to move back and forth on the surface of the object for grinding.

[0023] In the specific implementation manner, referring to Figure 3 , Figure 5 , the pressing assembly 4 includes a sliding frame body 412, a lifting frame body 422, a lifting mechanism 43 and a pressing wheel 44. The sliding frame body 412 is slidably installed on the side of the sub-guide rail 211. The lifting mechanism 43 is installed on the side of the sliding frame body 412 away from the sub-guide rail 211. The lifting frame body 422 is connected to the driving end of the lifting mechanism 43. The pressing wheel 44 is rotatably connected to the lifting frame body 422 and abuts against the inner surface of the grinding belt 5; in this solution, during operation, the sliding frame body 412 will move to a corresponding position on the sub-guide rail 211. The lifting frame is driven by the lifting mechanism 43 to approach the object, and the pressing wheel 44 presses the grinding belt 5. The grinding belt 5 will contact the object. During the rotation of the grinding belt 5, the pressing wheel 44 will also rotate accordingly. The pressing wheel 44 can provide a pushing and pressing effect for the grinding belt 5.

[0024] In the specific implementation manner, referring to Figure 2, a moving mechanism 22 is provided at the bottom of the frame body 2, and a counter 23 in contact with the guide rail 1 is installed at the front end of the moving mechanism 22. In this solution, the moving mechanism 22 is used to cooperate with the guide rail 1 to drive the entire device to operate, and the moving mechanism 22 is driven by a motor.

[0025] In the specific implementation manner, refer to Figure 3 , Figure 5 , V-shaped frames 47 are rotatably installed on both sides of the lifting frame body 422. Two support arms 45 are rotatably installed inside the V-shaped frames 47, and a V shape can be formed between the support arms 45. One end of the support arm 45 away from the V-shaped frame 47 is rotatably installed with a pressing wheel 44, and the pressing wheel 44 abuts against the inner surface of the grinding belt 5. Tension springs 46 are connected between the two support arms 45 and between the support arm 45 and the V-shaped frame 47; in this solution, when the entire lifting frame body 422 moves towards the object, when the two support arms 45 approach the object, due to the stepped contour of the object surface, the height positions of the ends of the two support arms 45 close to the object will be different, and there will be a gap between the pressing wheels 44 of the two support arms 45 close to the object. Therefore, the edges of the object will squeeze the grinding belt 5 between the two pressing wheels 44. At this time, the grinding belt 5 will be in close contact with the edges of the object, and after the grinding belt 5 is driven, the edges can also be ground; further, the included angle between the two support arms 45 can be adaptively changed according to the edges of the object.

[0026] In the specific implementation manner, refer to Figure 1 , Figure 2 , a cover body is provided on the periphery of the frame body 2, and the cover body is rotatably connected to the frame body 2. In this solution, the cover body is used to protect the grinding belt 5 and can prevent spattering of metal slag when the grinding belt 5 is grinding.

[0027] In the specific implementation manner, refer to Figure 1 , a translation mechanism 6 capable of driving the object to move is installed between the guide rails 1; the translation mechanism 6 in this solution is used to change the position of the object, and the translation mechanism 6 is a conveyor belt, which can drive the object to move to the corresponding position for convenient grinding work.

[0028] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
