Description

Technical Field

[0001] The utility model relates to the technical field of pipe rust removal, in particular to a rust removal device used for removing rust from the surface of a pipe. Background Art

[0002] The rust removal equipment for pipe surface rust removal mainly includes sandblasting equipment, shot blasting equipment, chemical rust removal equipment, ultrasonic rust removal equipment, electrochemical rust removal equipment and laser rust removal equipment. These equipment have different working principles and applicable scenarios when removing rust and dirt on the pipe surface. The selection of appropriate rust removal equipment needs to be determined according to the material, shape, degree of rust and production requirements of the pipe. Removing impurities such as rust and oxide scale can improve the cleanliness and flatness of the pipe surface, provide good surface adhesion for subsequent painting, plating and other processes, and extend the service life of the coating.

[0003] In the process of implementing this application, the inventor found that there are at least the following problems in this technology:

[0004] (1) If the pipe is unstable during processing, it is easy to cause dimensional errors, resulting in products that do not meet design requirements. Unstable clamping will cause the position of the pipe to shift during processing, resulting in shape deviation. The pipe is prone to friction with processing equipment or tools under unstable conditions, resulting in scratches or indentations on the surface. Due to unstable clamping, the position and clamping state of the pipe need to be adjusted frequently, which increases the operation time and process complexity.

[0005] (2) Compared with multi-group grinding devices, a small number of grinding devices can only process a smaller number of pipes at the same time, which prolongs the grinding process and reduces production efficiency. A small number of grinding devices cannot process multiple pipes at the same time during the grinding process, so it is difficult to ensure that each pipe can obtain the same grinding effect, which may lead to differences in surface quality and size between products. Due to the limited processing capacity of the small number of grinding devices, it may be necessary to increase the number of operators to meet production needs, thereby increasing labor costs. Utility Model Content

[0006] In view of the shortcomings of the prior art, the utility model provides a rust removal device for removing rust from the surface of pipes, which has the advantages of stable clamping of the polished pipes and rapid polishing with multiple groups of polishing devices, solving the problems of unstable quality caused by unstable clamping during polishing and slow polishing efficiency of a single group of polishing devices.

[0007] The utility model provides the following technical scheme: a rust removal device for removing rust from the surface of a pipe, comprising a base plate, the bottom end of the base plate is fixedly connected to an extension plate, the top of the extension plate is fixedly connected to a motor one, the output end of the motor one is fixedly connected to a transmission rod three, the bottom end of the transmission rod three is hinged with two groups of hinge blocks, the sides of the two groups of hinge blocks are fixedly connected to a transmission rod two, the inside of the transmission rod two is movably sleeved with a connecting rod three, the top of the connecting rod three is fixedly connected to the base plate, both ends of the transmission rod two are fixedly connected to the connecting rod two, the outer wall of the connecting rod two is movably sleeved with one end of the transmission rod one, the other end of the transmission rod one is movably sleeved with the connecting rod one, the inner top of the connecting rod one is fixedly connected to a connecting block two, the top of the connecting block two is fixedly connected to a connecting slider, and the top of the connecting slider is fixedly connected to a clamping block.

[0008] Preferably, the side of the clamping block is fixedly connected with a side baffle, the inner wall of the side baffle is fixedly connected with four groups of connecting blocks one, wherein the inner walls of two groups of connecting blocks one are movably sleeved with connecting shafts, and the outer wall of the connecting shaft is fixedly connected with two groups of grinding brushes.

[0009] Preferably, a slide groove is provided inside the bottom plate, and a connecting slider is movably sleeved inside the slide groove.

[0010] Preferably, the outer wall of one group of the connecting shafts is drivingly connected to one end of a transmission belt, and the other end of the transmission belt is drivingly connected to another group of connecting shafts.

[0011] Preferably, the top end of one group of the connecting shafts is fixedly connected to motor 2, and the bottom end of motor 2 is fixedly connected to connecting block 1.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The rust removal equipment for removing rust from the surface of pipes is as follows: the pipe to be rusted is placed on the upper end of the bottom plate, and the motor 1 is started. The output end of the motor 1 drives the transmission rod 3 to rotate with the motor 1 as the center, and then drives the hinged blocks on both sides to rotate synchronously inward, and then pulls the transmission rod 2 to rotate with the connecting rod 3 as the center, and at the same time, the connecting rods 2 on both sides drive the transmission rod 1 to rotate to one side, so that the connecting rod 1 drives the top connecting block 2 to slide inside the bottom plate, so that the top connecting slider moves synchronously, and then drives the top clamping block to stably clamp the internal pipe, so as to maintain the stability of grinding. Stable clamping can prevent the pipe from shifting and vibrating during the processing, thereby improving the processing accuracy, ensuring that the size and shape of the product meet the design requirements, ensuring that the processing results of each batch of pipes are consistent, reducing quality fluctuations, reducing the adjustment time before each processing, and speeding up the production rhythm. In the automated production line, stable clamping can realize continuous processing and improve production efficiency. Stable clamping can prevent the surface damage such as scratches and indentations caused by instability during the processing of the pipe.

[0014] 2. This type of rust removal equipment for rust removal on the surface of pipes starts motor 2, and the output end of motor 2 drives the connecting shaft to rotate inside the connecting block 1, thereby driving the grinding brush to grind the surface of the pipe. At the same time, the rotating connecting shaft drives another set of connecting shafts to rotate through the transmission belt, so that multiple sets of grinding brushes can synchronously grind and remove rust from the pipe to achieve the effect of rapid rust removal. Multiple sets of grinding devices are usually equipped with multiple abrasive groups, which can grind different parts of the pipe at the same time, improving the grinding efficiency. Compared with a single set of grinding devices, multiple sets of grinding devices can complete more grinding processes at the same time, reducing the production cycle. Multiple sets of grinding devices can ensure that each pipe can get the same grinding effect by precisely controlling the parameters and processes of each abrasive group. This consistency is very important, especially for pipe products that need to maintain a uniform appearance and size. Multiple sets of grinding devices usually use an automated control system, which can achieve fully automatic or semi-automatic operation. The operator only needs to set the grinding parameters and procedures, and the device can automatically perform the grinding process, reducing labor costs and the possibility of operating errors.
