Technical Field

[0001] The utility model relates to the technical field of rust removal of metal products, and more specifically, to a rust removal device for metal product processing. Background Art

[0002] The rust removal work of metal products is a common treatment method. In the processing of metal products, in order to ensure the normal progress of processing and the effect after processing, it is necessary to remove the rust on the metal products. At this time, a rust removal device is required. Currently, the most common rust removal device is usually a laser rust remover, also called a laser cleaning machine. Personnel hold the laser emission handle and irradiate the laser on the metal products, so that the rust removal operation of the metal products can be completed.

[0003] When the existing rust removal device removes rust from metal products, it is usually that personnel hold the handle to irradiate and remove rust from the metal products. If it is a small metal product, it will not be too laborious to hold and remove rust by hand. However, if the metal product is a metal pipe with a long length, then personnel need to hold the handle and move along the metal pipe all the time to remove rust, and it is also necessary to turn over the metal pipe. The operation is extremely troublesome, and the efficiency is also low. The labor intensity of personnel is high. In view of this, we propose a rust removal device for metal product processing. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, adapt to the actual needs, and provide a rust removal device for metal product processing to solve the technical problem that the current rust removal device for metal product processing is not convenient for rust removal operation of long pipe metal products.

When rust removal is required for long pipe metal products, the distance between the cooperating conveying structure and the rolling structure can be adjusted by the first electric push rod according to the diameter of the metal pipe. Then, the metal pipe is placed between the cooperating conveying structure and the rolling structure. At this time, the driving structure drives the rolling structure to rotate, the rolling structure drives the metal pipe to rotate, and then the cooperating conveying structure will cooperate with the metal pipe to rotate. Since the cooperating wheels in the cooperating conveying structure are arranged obliquely and have a certain oblique guiding effect, it is convenient for personnel to pull the metal pipe to move conveniently. During this process, the emission handle is placed on the L-shaped placement rack. As the metal pipe rotates and is conveyed, the laser emitted by the emission handle can directly complete the rust removal operation of the metal pipe without personnel holding the rust removal tool. The utility model also has a stabilizing structure arranged at both ends of the cooperating conveying structure. Therefore, after the long metal pipe is placed between the cooperating conveying structure and the rolling structure, the jacking structure in the stabilizing structure can drive the pressing structure to rotate, so that the arc groove of the pressing plate in the pressing structure presses above the long metal pipe and applies pressure to the long metal pipe, thereby increasing the friction between the long metal pipe and the cooperating conveying structure and the rolling structure, further ensuring the stable and uniform conveying of the metal pipe on the cooperating conveying structure and the rolling structure, and thus ensuring the rust removal effect on the long metal pipe.

At this time, the driving structure drives the rolling structure to rotate, the rolling structure drives the metal pipe to rotate, and then the matching conveying structure will rotate in cooperation with the metal pipe. Because the matching wheels in the matching conveying structure are inclined, it has a certain inclined guiding effect, which is convenient for personnel to pull the metal pipe to move conveniently. During this process, the emission handle is placed on the L-shaped placement rack. As the metal pipe rotates and is conveyed, the laser emitted by the emission handle can directly complete the rust removal operation of the metal pipe, without the need for personnel to hold the rust removal device, solving the technical problem that the existing rust removal device for metal product processing is not convenient for rust removal operation of long pipe metal products. Therefore, the present utility model has the advantages of high efficiency and convenience in rust removal of long pipe metal products.

[0017] 2. The present utility model also has a stabilizing structure arranged at both ends of the matching conveying structure. Therefore, after the long metal pipe is placed between the matching conveying structure and the rolling structure, the jacking structure in the stabilizing structure can drive the pressing structure to rotate, so that the arc groove of the pressing plate in the pressing structure presses on the upper part of the long metal pipe and applies pressure to the long metal pipe, thereby increasing the friction between the long metal pipe and the matching conveying structure and the rolling structure, and further ensuring the stable and uniform conveying of the metal pipe on the matching conveying structure and the rolling structure, and then ensuring the rust removal effect on the long metal pipe.

On one side of the top of the moving base 1, a laser rust removal machine 2 is arranged. The top of the laser rust removal machine 2 is connected to a transmitting handle 201 through a cable. On the side of the top of the moving base 1 opposite to the laser rust removal machine 2, a rolling structure 3 is arranged. At the center of the rolling structure 3 on one side of the top of the moving base 1, a driving structure 4 is arranged. A cooperating conveying structure 5 is slidably arranged on the top of the moving base 1. The rolling structure 3 is located between the driving structure 4 and the cooperating conveying structure 5. Symmetric first electric push rods 6 are arranged before and after the moving base 1. The piston ends of the first electric push rods 6 are connected to the cooperating conveying structure 5. At the center between the laser rust removal machine 2 and the cooperating conveying structure 5 on the top of the moving base 1, an L-shaped placement rack 8 is arranged. On the top of the L-shaped placement rack 8, a placement groove 801 is arranged. When rust removing a long metal pipe, the transmitting handle 201 is placed in the placement groove 801 of the L-shaped placement rack 8. According to the diameter of the metal pipe, the first electric push rod 6 can drive the cooperating conveying structure 5 to displace, so as to adjust the distance between the cooperating conveying structure 5 and the rolling structure 3. Then the metal pipe is placed between the cooperating conveying structure 5 and the rolling structure 3. Then the driving structure 4 drives the driving roller shaft 303 on the rolling structure 3 to rotate. At this time, the driving roller shaft 303 drives the metal pipe to rotate, and the inclined cooperating wheel 503 on the cooperating conveying structure 5 rotates together with the metal pipe. When the cooperating wheel 503 rotates, it has a forward guiding effect on the metal pipe, so as to facilitate the operator to conveniently pull the metal pipe to move. During this process, the laser emitted by the transmitting handle 201 irradiates on the metal pipe, thereby completing the automatic rust removal operation of the metal pipe. There is no need for the operator to hold the transmitting handle 201 for rust removal, which greatly improves the efficiency and convenience of rust removing the long metal pipe.

The first pulley 402 drives the second pulley 404 to rotate through the transmission belt 403. The second pulley 404 drives the installation shaft 301 to rotate. The installation shaft 301 drives the driving roller shaft 303 to rotate. During the rotation of the driving roller shaft 303, the metal pipe is driven to rotate.

[0030] Further, the cooperating conveying structure 5 includes a bottom plate 501. A plurality of groups of second brackets 502 are arranged obliquely on the top of the bottom plate 501. A cooperating wheel 503 is rotatably arranged inside the second bracket 502. The obliquely arranged cooperating wheel 503 rotates together with the metal pipe and realizes the forward guiding effect on the metal pipe.

[0031] Furthermore, two symmetric sliding grooves 101 are formed in the top of the moving base 1, and a slider 102 is slidably arranged inside the sliding groove 101. The slider 102 is connected to the bottom plate 501. With the cooperation of the sliding groove 101 and the slider 102, the sliding installation of the bottom plate 501 is realized. Therefore, the cooperating conveying structure 5 can slide on the moving base 1.

[0032] In the embodiment of the present utility model, stabilizing structures 7 are arranged at both ends of the cooperating conveying structure 5. The stabilizing structure 7 includes a support 9, a jacking structure 10 and a pressing structure 11. The support 9 is arranged on the cooperating conveying structure 5. The jacking structure 10 is arranged on the top of the support 9. The pressing structure 11 is rotatably arranged on one side of the top of the support 9. After the long metal pipe is placed between the cooperating conveying structure 5 and the rolling structure 3, then the jacking structure 10 in the stabilizing structure 7 can drive the pressing structure 11 to rotate, so that the arc groove 1106 of the pressing plate 1105 in the pressing structure 11 presses on the upper part of the long metal pipe and applies pressure to the long metal pipe, thereby increasing the friction between the long metal pipe and the cooperating conveying structure 5 and the rolling structure 3, further ensuring the stable and uniform conveying of the metal pipe on the cooperating conveying structure 5 and the rolling structure 3, and further ensuring the rust removal effect on the long metal pipe.

[0033] Specifically, the jacking structure 10 includes a first welding block 1001, which is arranged on one side of the top of the support 9. A second electric push rod 1002 is arranged in the center of one side of the first welding block 1001. A triangular block 1003 is arranged at the piston end of the second electric push rod 1002, and the inclined surface of the triangular block 1003 faces upward. The pressing structure 11 includes a third support 1101, which is arranged on the side of the top of the support 9 opposite to the jacking structure 10.

An arc groove 1106 is opened at one end of the bottom of the pressing plate 1105, and a number of pressing roller shafts 1107 are rotatably arranged inside the arc groove 1106. When the second electric push rod 1002 drives the triangular block 1003 to displace, under the cooperation of the inclined surface of the triangular block 1003 and the matching roller 1104, the mounting plate 1102 and the pressing plate 1105 will be driven to rotate. Then, the arc groove 1106 of the pressing plate 1105 will press on the metal tube, and the metal tube can rotate normally when the arc groove 1106 contacts the metal tube through the pressing roller shafts 1107 inside the arc groove 1106.

[0034] Furthermore, insertion rods 1108 are arranged at both ends of the bottom of the pressing plate 1105 on the side facing the mounting plate 1102, and the insertion rods 1108 are inserted into the mounting plate 1102. A second welding block 1109 is arranged on the side of the top of the mounting plate 1102 opposite to the pressing plate 1105. A screw rod 11010 is rotatably arranged on one side of the second welding block 1109, and the screw rod 11010 is screwed into the pressing plate 1105. During use, according to the placement of the metal tube, the screw rod 11010 can be rotated. At this time, the pressing plate 1105 will displace on the mounting plate 1102, so as to adjust the position of the arc groove 1106, so that the arc groove 1106 can press on the metal tube.

[0035] Working principle: This embodiment provides a rust removal device for metal product processing.

Then, the metal pipe is placed between the matching conveying structure 5 and the rolling structure 3. Then, the driving structure 4 drives the driving roller shaft 303 on the rolling structure 3 to rotate. At this time, the driving roller shaft 303 drives the metal pipe to rotate, and the inclined matching wheel 503 on the matching conveying structure 5 rotates together with the metal pipe. And when the matching wheel 503 rotates, it has an effect of guiding the metal pipe to move forward, thus facilitating the operator to conveniently pull the metal pipe to move. During this process, the laser emitted by the emission handle 201 irradiates on the metal pipe, thereby completing the automatic rust removal operation of the metal pipe. There is no need for the operator to hold the emission handle 201 for rust removal, greatly improving the high efficiency and convenience of rust removing the long metal pipe;

[0036] Secondly, after the long metal pipe is placed between the matching conveying structure 5 and the rolling structure 3, then the jacking structure 10 in the stabilizing structure 7 can drive the pressing structure 11 to rotate, so that the arc groove 1106 of the pressing plate 1105 in the pressing structure 11 presses above the long metal pipe and applies pressure to the long metal pipe, thereby increasing the friction between the long metal pipe and the matching conveying structure 5 and the rolling structure 3, further ensuring the stable and uniform conveying of the metal pipe on the matching conveying structure 5 and the rolling structure 3, and thus ensuring the rust removal effect on the long metal pipe.
