Description

Technical Field

[0001] This utility model relates to the field of metal tube polishing technology, and in particular to a multi-stage grinding and polishing device for metal tube processing. Background Technology

[0002] In the industrial manufacturing sector, a large number of metal pipes are used. During the production and processing of metal pipes, they are ground and polished to meet the standards for use. Existing metal pipe grinding equipment usually only grinds the metal pipe once, and the operation process is relatively cumbersome, resulting in poor grinding effect and low ease of use.

[0003] A search revealed a patent with publication number CN112518536A, which discloses a multi-stage grinding and polishing device for metal pipe processing. The device includes a base, a threaded screw a rotatably connected to the inner wall of the base, a metal pipe fixing assembly threadedly connected to the circumferential side of the threaded screw a, a pipe wall cleaning mechanism fixedly connected to the upper surface of the base, a threaded screw b rotatably connected to the inner wall of the base, a first-stage grinding mechanism threadedly connected to the circumferential side of the threaded screw b, and a second-stage grinding mechanism fixedly connected to the upper surface of the base. The metal pipe fixing assembly includes a movable seat, the inner wall of which is threadedly connected to the threaded screw a, a support fixedly connected to one surface of the movable seat, and a fixed seat fixedly connected to another surface of the support. This patent, through the design of the metal pipe fixing assembly, the pipe wall cleaning mechanism, the first-stage grinding mechanism, and the second-stage grinding mechanism, solves the problem that existing metal pipe grinding devices only grind the metal pipe once and have a cumbersome operation process, resulting in poor practicality.

[0004] The patented multi-stage grinding of metal tubes requires a metal tube fixing component to move the metal tube sequentially to the positions of the first-stage grinding mechanism and the second-stage grinding mechanism, thereby performing two all-round grindings on the metal tube. This makes the grinding process relatively cumbersome and time-consuming. At the same time, because the equipment needs to clamp the metal tube during grinding, it cannot grind long tubes, which limits the scope of application of the equipment. Therefore, this application proposes a multi-stage grinding and polishing device for metal tube processing. Utility Model Content

[0020] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Example

[0021] Please see Figures 1-4 This utility model provides a technical solution: a multi-stage grinding and polishing device for metal pipe processing, including a frame 1 and a rotating drum 4. Two side plates 2 are symmetrically fixedly connected to the top of the frame 1. Connecting cylinders 3 are rotatably connected inside the two side plates 2. A rotating drum 4 is fixedly connected between the two connecting cylinders 3. The two connecting cylinders 3 and the rotating drum 4 are connected to each other, allowing metal steel pipes to enter and exit. Multiple T-shaped rods 6 are symmetrically and equidistantly slidably connected inside the rotating drum 4. A coarse grinding plate 7, a fine grinding plate 8, and a fine grinding plate 9 are fixedly connected to the ends of two T-shaped rods 6 that are close to each other. There are six T-shaped rods 6, with two rods corresponding to each other as a group. The three groups of T-shaped rods 6 are sequentially installed with coarse grinding plates 7, fine grinding plates 8, and fine grinding plates 9 in the direction of metal steel pipe entry, so that the metal steel pipe can be gradually refined during the movement of the metal steel pipe. A drive assembly 5 for rotating the connecting cylinders 3 is provided at the bottom of the frame 1. An adjustment assembly 11 for adjusting the spacing of the T-shaped rods 6 is provided on the outside of the rotating drum 4.

[0022] Furthermore, the drive assembly 5 includes a base plate 51, which is fixed to the bottom of the frame 1. A motor 52 is fixedly connected to the upper surface of the base plate 51. An active synchronous pulley 53 is fixedly connected to the output end of the motor 52. A driven synchronous pulley 54 is fixedly sleeved on the outer side of one of the connecting cylinders 3. A synchronous belt 55 is provided between the active synchronous pulley 53 and the driven synchronous pulley 54. The synchronous belt 55 can transmit the power of the motor 52 to the driven synchronous pulley 54, thereby driving the connecting cylinder 3 and the rotating cylinder 4 to rotate. This causes the rotating cylinder 4 to drive the internal coarse grinding plate 7, fine grinding plate 8 and fine grinding plate 9 to rotate, thereby grinding and polishing the metal steel pipe and improving processing efficiency.

[0023] Furthermore, each T-shaped rod 6 is fitted with a tension spring 10 on its outer side, and the two ends of the tension spring 10 are fixedly connected to the inner wall of the T-shaped rod 6 and the rotating cylinder 4 respectively, which can drive the T-shaped rod 6 to reset, thereby expanding the distance between the two T-shaped rods 6 to accommodate large-diameter metal steel pipes.

[0024] Furthermore, the adjustment assembly 11 includes a slide cylinder 111, which is slidably disposed outside the rotating cylinder 4. Multiple push blocks 112 are symmetrically and equidistantly fixed inside the slide cylinder 111, and each push block 112 is in contact with one end of a corresponding T-shaped rod 6. A threaded groove 114 is provided on the outside of the rotating cylinder 4, and a bolt 113 is threadedly connected to the outside of the threaded groove 114. The bolt 113 is rotatably connected to one side of the slide cylinder 111. By rotating the bolt 113, the slide cylinder 111 can be driven to slide outside the rotating cylinder 4, thereby causing the push blocks 112 inside to cooperate with the T-shaped rods 6 and drive the T-shaped rods 6 to move, so as to change the spacing between the T-shaped rods 6 and adapt to metal steel pipes of different diameters.

[0025] Furthermore, a fixing plate 12 is fixedly connected to the outside of the rotating cylinder 4. One end of the fixing plate 12 extends into the inside of the sliding cylinder 111, and the sliding cylinder 111 and the fixing plate 12 are slidably connected. The fixing plate 12 can prevent the sliding cylinder 111 from rotating outside the rotating cylinder 4, avoid misalignment between the push block 112 inside and the T-shaped rod 6, and ensure that the movement of the sliding cylinder 111 and the push block 112 can drive the T-shaped rod 6 to slide.

[0026] Furthermore, multiple chip removal grooves 13 are equidistantly provided inside the rotating drum 4. A retaining ring 14 is fixedly connected to the side plate 2 away from the driven synchronous pulley 54, and the retaining ring 14 is located directly above the chip removal groove 13. The retaining ring 14 can prevent the chips inside the rotating drum 4 from being thrown upward. A chip collection hopper 15 is provided between the two crossbeams of the frame 1. The chip collection hopper 15 is located directly below the chip removal groove 13 and can collect the chips.

[0027] In summary: When using this equipment to grind and polish metal pipes, first insert one end of the metal pipe into the rotating drum 4 through the connecting cylinder 3. Then rotate the bolt 113 on the outside of the rotating drum 4. At this time, the bolt 113 engages with the threaded groove 114, causing the sliding cylinder 111 to slide outside the rotating drum 4. Since the rotating drum 4 is equipped with a fixing plate 12 that slides with the sliding cylinder 111, the sliding cylinder 111 can be prevented from rotating outside the rotating drum 4. At the same time, the pushing block 112 inside the sliding cylinder 111 presses the T-shaped rod 6, causing the T-shaped rod 6 to drive the tension spring 10 to stretch. The coarse grinding plate 7, fine grinding plate 8, and fine grinding plate 9 on the T-shaped rod 6 are in contact with... The outer wall of the metal pipe comes into contact with the metal pipe, and then the motor 52 drives the active synchronous pulley 53 to rotate. With the cooperation of the active synchronous pulley 53 and the synchronous belt 55, the driven synchronous pulley 54 rotates. At this time, the driven synchronous pulley 54 drives the connecting cylinder 3 and the rotating cylinder 4 to rotate. When the rotating cylinder 4 rotates, it drives the coarse grinding plate 7, fine grinding plate 8 and fine grinding plate 9 inside to rotate, thereby polishing the metal pipe. One end of the rotating cylinder 4 is provided with multiple chip discharge grooves 13. The dust and debris generated by polishing the metal pipe can be discharged from the inside of the rotating cylinder 4 through the chip discharge grooves 13 and fall into the chip collection hopper 15 set at the bottom of the frame 1 for convenient centralized treatment.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
