Description

Technical Field

[0001] This invention relates to the field of polishing technology, and more specifically to a surface wire drawing and polishing device for metal parts. Background Technology

[0002] Brush polishing is suitable for metal materials such as stainless steel, aluminum, and copper. Compared with mirror polishing, brush polishing can weaken minor scratches, dents, and other defects on the material surface, and has slightly lower requirements for the flatness of the substrate; at the same time, it can effectively reduce the reflection of metal materials after polishing.

[0003] For example, Chinese patent CN119159493B discloses a metal plate polishing and wire drawing equipment. After polishing and wire drawing one side of the metal plate through a set of polishing and wire drawing devices, the metal plate with the polished and wire drawn side can be flipped 180° and placed in another set of polishing and wire drawing devices to further polish and wire draw the other side of the metal plate.

[0004] However, this device is suitable for flat metal components. For some round cap-shaped metal parts, both the annular side and the cross-section need to be brushed and polished. Existing devices require simultaneous brushing and polishing of the cross-section and side in separate processes, which is less efficient.

[0005] Based on this, the present invention designs a surface brushing and polishing device for metal parts to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a surface wire drawing and polishing device for metal parts.

[0012] Furthermore, the end face drawing assembly includes a moving module, a replacement module, and a drawing and polishing belt. The moving module is mounted on the machine base, the replacement module is mounted on the moving end of the moving module, and the replacement module is equipped with a drawing and polishing belt for polishing the end face of the round cover.

[0013] Furthermore, the mobile module includes a second linear module and a mobile mounting bracket. The second linear module is fixed on the machine base, and the mobile end of the second linear module is fixedly mounted with the mobile mounting bracket.

[0014] Furthermore, the replacement module includes guide rollers, a take-up reel, an unwind reel, end mounting blocks, and rotating rollers.

[0017] Compared with the prior art, the beneficial effects of this invention are as follows: The automatic feeding mechanism continuously feeds material, moving the round cover to the rotating support module.

Then, the edge polishing component and the end face drawing component move towards the rotating support module, bringing the side of the round cover into contact with the edge polishing component and the front end of the round cover into contact with the end face drawing component. The rotating support module drives the round cover to rotate, thereby cooperating with the edge polishing component to polish and draw the side of the round cover, and simultaneously cooperating with the end face drawing component to polish and draw the end face of the round cover. This achieves simultaneous polishing and drawing of the front end and side of the round cover, improving the overall polishing and drawing efficiency. After the round cover is polished and drawn, the edge polishing component and the end face drawing component reset, and the guiding module is operated to move to the front of the rotating support module. Then, the unloading module pushes the round cover after polishing and drawing into the guiding module for unloading. This achieves continuous feeding, drawing, polishing, and unloading of the round cover, further improving the overall processing efficiency. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0023] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-3 A surface wire drawing and polishing device for metal parts includes a machine base 1 and an automatic feeding mechanism 2; it also includes a wire drawing and polishing mechanism 3 and a feeding mechanism 4; An automatic feeding mechanism 2 for feeding materials is installed on the right side of the machine base 1, and a wire drawing and polishing mechanism 3 is installed on the left side of the machine base 1. like Figure 2 and Figure 3 As shown, the wire drawing and polishing mechanism 3 includes a rotary support module 31, an edge polishing component 32, and an end face wire drawing component 33. The rotary support module 31 for fixing the round cover 5 and driving the round cover 5 to rotate is installed on the rear side of the machine base 1. The edge polishing component 32 for wire drawing and polishing the edge of the round cover 5 is installed on the left side of the machine base 1. The end face wire drawing component 33 for wire drawing and polishing the end face of the round cover 5 is installed on the front side of the machine base 1. A feeding mechanism 4 is installed on the rotary support module 31 and the machine base 1. like Figure 3 As shown, the unloading mechanism 4 includes an unloading module 41 and a guiding module 42. The guiding module 42 for guiding the round cover 5 is installed on the machine base 1. The guiding module 42 is located between the rotary support module 31, the edge polishing component 32, the end face wire drawing component 33 and the automatic feeding mechanism 2. The unloading module 41 for dropping the round cover 5 onto the guiding module 42 is installed on the rotary support module 31.

[0024] In this embodiment, when the surface brushing and polishing device for the metal parts is working normally, the automatic feeding mechanism 2 continuously feeds the material, causing the round cover 5 to move to the rotary support module 31. After the rotary support module 31 clamps the round cover 5, the automatic feeding mechanism 2 resets. Then, the edge polishing assembly 32 and the end face brushing assembly 33 move towards the rotary support module 31, so that the side of the round cover 5 contacts the edge polishing assembly 32 and the front end of the round cover 5 contacts the end face brushing assembly 33. The rotary support module 31 drives the round cover 5 to rotate, thereby cooperating with the edge polishing assembly 32 to polish the side of the round cover 5. The process involves wire drawing, simultaneously polishing and wire drawing the end face of the round cover 5 in conjunction with the end face wire drawing component 33; this allows for simultaneous polishing and wire drawing of the front end and sides of the round cover 5, improving the overall polishing and wire drawing efficiency; after the round cover 5 is polished and wire drawn, the edge polishing component 32 and the end face wire drawing component 33 are reset, and the material guiding module 42 is operated to move to the front of the rotating support module 31. Then, the unloading module 41 pushes the round cover 5, which has been polished and wire drawn, into the material guiding module 42 for unloading; this achieves continuous feeding, wire drawing, polishing, and unloading of the round cover 5, further improving the overall processing efficiency.

[0025] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figure 4 and Figure 5 As shown, the automatic feeding mechanism 2 includes a feeding rack 21 and a transfer module 22. The feeding rack 21 for feeding materials is fixedly installed on the machine base 1, and the transfer module 22 for transferring the round cover 5 in the feeding rack 21 to the rotary support module 31 is installed on the machine base 1. The feeding rack 21 has an inclined groove 211, and the lower left side of the feeding rack 21 has an opening for the round cover 5 to fall into the transfer module 22. The round cover 5 rolls in the inclined groove 211. The transfer module 22 includes a linear cylinder module 221, a moving frame 222, a baffle 223, a feeding cylinder 225, and an electromagnet 226.

The feeding cylinder 225 is fixedly installed on the front side of the moving frame 222. The output end of the feeding cylinder 225 is fixedly installed with the electromagnet 226. When the movable frame 222 is on the right, the conformal groove 224 is aligned with the lower opening of the feeding frame 21; when the movable frame 222 is on the left, the conformal groove 224 is aligned with the rotating support module 31.

[0026] like Figure 4 , Figure 6 and Figure 7As shown, the rotary support module 31 includes a fixed support frame 311, a rotary drive motor 312, a rotating disk 313, and an internally supported pneumatic gripper 314. The fixed support frame 311 is fixedly installed on the machine base 1, and the rotary drive motor 312 is fixedly installed on the fixed support frame 311. The rotating disk 313 is rotatably installed on the fixed support frame 311, and the output end of the rotary drive motor 312 is fixedly connected to the rotating disk 313. An internally supported pneumatic gripper 314 for supporting the round cover 5 is fixedly installed on the rotating disk 313. When the internally supported pneumatic gripper 314 is deployed, the circle formed by the front ends of the multiple grippers of the internally supported pneumatic gripper 314 is the same as the inner diameter of the round cover 5, and the circle formed by the rear ends of the multiple grippers of the internally supported pneumatic gripper 314 is smaller than the inner diameter of the round cover 5.

[0027] The edge polishing assembly 32 includes a linear module 321, a movable support frame 322, a grinding drive motor 323, and a wire-brushing polishing wheel 324. The linear module 321 is fixedly installed on the machine base 1. The movable end of the linear module 321 is fixedly installed with the movable support frame 322, and the grinding drive motor 323 is fixedly installed on the movable support frame 322. The output end of the grinding drive motor 323 is fixedly installed with a wire-brushing polishing wheel 324 for grinding the side of the round cover 5.

[0028] The end face drawing assembly 33 includes a moving module, a replacement module, and a drawing and polishing belt 336. The moving module is installed on the machine base 1, and the replacement module is installed on the moving end of the moving module. The replacement module is equipped with a drawing and polishing belt 336 for polishing the end face of the round cover 5. The moving module includes a linear module 331 and a moving mounting bracket 332. The linear module 331 is fixed on the machine base 1, and the moving end of the linear module 331 is fixedly mounted with the moving mounting bracket 332. The replacement module includes guide rollers 333, take-up reel 334, unwind reel 335, end mounting blocks 337, and rotating rollers 338. Guide rollers 333 are symmetrically and rotatably mounted on a movable mounting frame 332. A take-up reel 334 driven by a servo motor is rotatably mounted on the movable mounting frame 332. An unwind reel 335 driven by a servo motor is rotatably mounted on the movable mounting frame 332. End mounting blocks 337 are fixedly mounted on the movable mounting frame 332, and rotating rollers 338 are rotatably mounted on the end mounting blocks 337. The two ends of the wire drawing and polishing belt 336 are fixedly connected to the take-up reel 334 and the unwind reel 335, respectively. The middle part of the wire drawing and polishing belt 336 passes around the outside of the rotating rollers 338 and the two guide rollers 333.

[0029] In this embodiment, when the automatic feeding mechanism 2 and the wire drawing and polishing mechanism 3 are working normally, the round cover 5 rolls from right to left in the conformal inclined groove 211, and the round cover 5 on the left side falls into the conformal groove 224 from the lower opening of the feeding frame 21; at the same time, the electromagnet 226 is activated to attract the round cover 5, ensuring the stability of the round cover 5; the cylinder linear module 221 drives the moving frame 222 to move horizontally, thereby driving the round cover 5 to move horizontally to the front of the inner support pneumatic gripper 314 through the conformal groove 224. During this process, the baffle 223 moves to the opening of the feeding frame 21. The opening of the feeding rack 21 is blocked on the lower side; the feeding cylinder 225 drives the electromagnet 226 to move horizontally, thereby pushing the round cover 5 attracted by the electromagnet 226 onto the gripper of the inner support pneumatic gripper 314; the pneumatic inner support pneumatic gripper 314 fixes the round cover 5, closes the electromagnet 226, and the feeding cylinder 225 drives the electromagnet 226 to reset; then the cylinder linear module 221 drives the moving frame 222, the baffle 223, the feeding cylinder 225 and the electromagnet 226 to reset, thereby realizing the feeding of the round cover 5; After the material is loaded, linear module one 321 drives the movable support frame 322, the grinding drive motor 323, and the wire drawing and polishing wheel 324 to move horizontally until the edge of the wire drawing and polishing wheel 324 contacts the side of the round cover 5; linear module two 331 drives the movable mounting frame 332, the guide roller 333, the take-up reel 334, the unwinding reel 335, the wire drawing and grinding belt 336, the end mounting block 337, and the rotating roller 338 to move horizontally until the wire drawing and grinding belt 336, which is in contact with the outside of the rotating roller 338, contacts the upper end face of the round cover 5; at this time, the rotary drive motor 312 drives the rotating disk 313 to rotate, thereby driving the round cover 5 to rotate through the internal support pneumatic gripper 314; The grinding drive motor 323 drives the wire drawing and polishing wheel 324 to rotate, thereby polishing and drawing the side of the round cover 5 through the wire drawing and polishing wheel 324; and during the rotation of the round cover 5, the end face of the round cover 5 is polished and drawn through the wire drawing and grinding belt 336 that contacts the outside of the rotating roller 338, so as to achieve synchronous processing; after the processing is completed, the rotary drive motor 312 is turned off to stop the rotation of the rotating disk 313 and the inner support pneumatic gripper 314; the linear module one 321 drives the movable support frame 322, the grinding drive motor 323 and the wire drawing and polishing wheel 324 to reset, and the linear module two 331 drives the movable mounting frame 332 and the structure installed on the movable mounting frame 332 to reset; After the wire drawing and polishing belt 336 is used, in order to ensure the consistency of wire drawing and polishing, the take-up reel 334 and the unwind reel 335 can be started. The take-up reel 334 drives the wire drawing and polishing belt 336 to take up, and the unwind reel 335 drives the wire drawing and polishing belt 336 to unwind. This causes the wire drawing and polishing belt 336 to move outside the guide roller 333 and the rotating roller 338, and the wire drawing and polishing belt 336 that has not been wire drawing and polished on the unwind reel 335 is moved to the outside of the rotating roller 338 for the next round of wire drawing and polishing. This realizes the automatic replacement of the wire drawing and polishing belt 336.

[0030] Example 3: In some embodiments, such as Figure 5 and Figure 7 As shown, in a preferred embodiment of the present invention, the feeding module 41 includes a feeding cylinder 411, an annular push plate 412, and a feeding guide frame 413. The feeding cylinder 411 is fixedly mounted on the fixed support frame 311. The annular push plate 412 is fixedly mounted on the output end of the feeding cylinder 411. The feeding guide frame 413 is fixedly mounted on the annular push plate 412. The inner diameter of the feeding guide frame 413 is larger than the inner diameter of the round cover 5. The feeding guide frame 413 is sleeved on the outside of the gripper of the inner support pneumatic gripper 314, and the center line of the feeding guide frame 413 coincides with that of the rotating disk 313.

[0031] The material guiding module 42 includes a clearance cylinder 421, a moving plate 422, an electromagnet 423, and a material guiding frame 424. The clearance cylinder 421 is fixedly installed on the lower side of the machine base 1. The moving plate 422 is fixedly installed on the output end of the clearance cylinder 421. The electromagnet 423 is fixedly installed on the upper side of the moving plate 422. The material guiding frame 424 is fixedly installed on the machine base 1. The material guiding frame 424 has an inclined material guiding groove 425.

[0032] In this embodiment, when the unloading module 41 and the guiding module 42 are working normally, after the wire drawing and polishing are completed, the positioning cylinder 421 drives the moving plate 422 and the electromagnet 423 to move vertically, so that the electromagnet 423 moves to the front side of the inner support pneumatic gripper 314; at this time, the inner support pneumatic gripper 314 retracts and is no longer tightly supported on the inner side of the round cover 5; the unloading cylinder 411 is operated, so that the unloading cylinder 411 drives the annular push plate 412 and the unloading guide frame 413 to move, and the unloading guide is guided by the unloading cylinder. The frame 413 pushes the round cover 5 out from the outside of the inner support pneumatic gripper 314, so that the inner support pneumatic gripper 314 is released from the electromagnet 423; the electromagnet 423 fixes and blocks the round cover 5; then the displacement cylinder 421 drives the moving plate 422 and the electromagnet 423 to reset, thereby driving the round cover 5 to move vertically downward until the round cover 5 contacts the guide groove 425. At this time, the electromagnet 423 is turned off; the round cover 5 rolls down along the guide groove 425 under the action of gravity; thus realizing automatic feeding.
