Description

Technical Field

[0001] The invention relates to the technical field of metal processing, in particular to a surface polishing treatment device and a treatment method for metal processing. Background Art

[0002] In the field of metal processing, polishing of the metal tube surface is an important process link, which plays a key role in improving the surface quality, aesthetics and subsequent performance of the metal tube. Traditional metal tube polishing equipment has many shortcomings in practical applications. For example, in terms of the transmission and positioning of the metal tube, there is often a lack of accurate and stable centering mechanism. The metal tube is prone to positional displacement during the transmission process, which not only leads to uneven polishing and affects the polishing quality, but also may damage the metal tube or the equipment itself due to the collision between the metal tube and the equipment parts. At the same time, in the cleaning link before polishing, most equipment does not pay enough attention. In the process of rough processing to fine processing, various dust, impurities and other pollutants will adhere to the surface of the metal tube. If these pollutants are not effectively removed before polishing, during the polishing and fine processing process, the pollutants may be embedded in the surface of the metal tube, forming scratches or pitting, which seriously reduces the surface finish of the metal tube. At the same time, it will also accelerate the wear of the polishing roller and shorten the service life of the polishing roller; In addition, traditional equipment also has defects in the relative positioning and support of the metal tube and the polishing roller. It cannot ensure that the metal tube is always in the optimal polishing position during the polishing process. Insufficient contact between the metal tube and the polishing roller may occur, resulting in unsatisfactory polishing effect and requiring secondary polishing, which reduces production efficiency. Summary of the invention

[0005] Preferably, a spring is connected between the support seat and the support slide rod, and the support slide rod is fitted with the inner surface of the metal tube through a centering wheel.

[0006] By adopting the above technical solution, the elastic effect of the spring is utilized to enable the support slide rod to ensure that the centering wheel always fits tightly against the inner side of the metal tube, thereby effectively maintaining the stability of the center position of the metal tube during the transmission process.

[0007] Preferably, one end of the position-limiting electric push rod is rotatably connected to an end of the piston rod located outside the piston cavity, and the piston rod and the piston cavity are connected in a sliding friction manner.

[0008] By adopting the above technical solution, the internal pressure of the piston cavity can be accurately adjusted through the flexible driving of the piston rod by the limiting electric push rod, thereby ensuring the stable limiting of the metal tube.

[0009] Preferably, the support push rod and the limiting rotary rod are connected by sliding friction, and the internal cavity of the limiting rotary rod where the support push rod is located is connected to one end of the piston cavity, a spring is connected between the support push rod and the limiting rotary rod, and the end of the support push rod located outside the limiting rotary rod is hemispherical in design, and the hemispherical end of the support push rod is in contact with the inner surface of the contact plate.

[0010] By adopting the above technical solution, the support push rod can effectively transmit pressure and change the angle of the contact plate through the fitting design of the hemispherical end and the contact plate, so that the contact plate can better fit the inner wall of the metal tube.

[0013] Preferably, a conveying and cleaning mechanism is provided on the surface of the mounting seat, which ensures that the subsequent polishing effect is not affected by cleaning the dust on the surface of the metal pipe during the conveying process; The conveying and cleaning mechanism includes: a conveying motor, which is fixedly mounted on the outer surface of a mounting seat, and an output shaft of the conveying motor passes through the inner surface of the mounting seat, and one end of the output shaft of the conveying motor is fixedly connected to a linkage gear, a rotating cleaning conveying roller is mounted on the inner surface of the mounting seat, and transmission gears are fixedly arranged on the outer surfaces of both ends of the cleaning conveying roller.

[0015] Preferably, the cleaning and conveying roller is meshed with the linkage gear through a transmission gear, and the two cleaning and conveying rollers are respectively located on the upper and lower sides of the center rod, and the outer surfaces of the cleaning and conveying rollers above the center rod are evenly provided with bristles, and the minimum distance between the outer surface of the upper cleaning and conveying roller and the axis of the center rod is greater than the minimum distance between the outer surface of the lower cleaning and conveying roller and the axis of the center rod.

[0016] By adopting the above technical solution, the stable rotation of the cleaning and conveying roller is achieved with the help of the precise meshing of the transmission gear and the linkage gear. The position design of the upper and lower rollers and the brush setting of the upper roller can effectively remove dust and impurities on the surface of the metal pipe during the conveying process, thereby improving the cleanliness of the metal pipe before polishing.

[0017] Preferably, the surfaces of the base and the mounting seat are provided with auxiliary positioning mechanisms, which enable the metal tube to be stably and fully polished by the polishing roller at a predetermined position by positioning and supporting the metal tube and the polishing roller; The auxiliary positioning mechanism includes: a clamping electric push rod, which is fixedly arranged on the outer surface of the upper end of the mounting seat, and a sliding clamping plate is installed on the outer surface of the mounting seat, and the clamping plate is fixedly connected to the lower end of the clamping electric push rod, a rotating piston cylinder is installed on the lower surface of the clamping plate, and a sliding clamping rod is installed on the lower end of the piston cylinder, and a rotating contact wheel is installed on the lower end of the clamping rod, a lifting rod is fixedly arranged on the outer surface of the upper end of the lower locking electric push rod, and limiting holes are evenly opened on the outer surfaces of both ends of the polishing roller, a sliding lifting frame is installed on the upper surface of the base, and a sliding contact frame is installed on the lower end of the lifting frame.

[0020] By adopting the above technical solution, the cooperation between the lifting rod, the contact frame and the lifting frame can stably support the polishing roller and ensure its stability during the polishing process.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: the surface polishing treatment equipment for metal processing: 1. The inner surface of the metal tube is supported by a center rod, a supporting slide rod and a centering wheel, so that the metal tube can be accurately moved to the surface of the driving roller during transportation to avoid deviation during transportation; Furthermore, by pre-expanding one side of the contact plate during the transportation of the metal tube, the outer surface of the expanded contact plate is abutted against the inner surface of the moving metal tube, so that the metal tube can be limited after being transported to the desired position. At the same time, the contact plate on the other side is expanded to complete the stable limitation of the metal tube, ensuring that the metal tube will not move laterally during the polishing process.

[0022] 2. The cleaning conveying roller in the conveying cleaning mechanism is connected by the meshing connection of the transmission gear and the linkage gear, realizing the coordinated operation with the conveying motor. The cleaning conveying roller with bristles above the center rod can comprehensively and efficiently clean the surface of the metal tube during the conveying process of the metal tube. The specific design of the distance between the outer surface and the axis of the center rod enables the bristles to fully contact all parts of the surface of the metal tube, effectively removing dust, impurities and other pollutants attached to the metal tube during processing, transportation or storage. This not only improves the surface quality of the metal tube, avoids the damage of pollutants to the metal tube and the polishing roller during the polishing process, but also prolongs the service life of the polishing roller and reduces the maintenance cost of the equipment; Furthermore, through such a design, the cleaning operation can be completed synchronously during the conveying process without increasing the floor space of the equipment. Compared with the traditional equipment that requires separate cleaning stations and conveying devices, the present invention greatly improves the compactness and efficiency of the production process. 3. The clamping electric push rod in the auxiliary positioning mechanism drives the clamping plate to move up and down, and then applies appropriate pressure to the metal tube through the piston cylinder, clamping rod and contact wheel. This design can accurately adjust the contact state between the metal tube and the polishing roller according to the specific situation of the metal tube, ensuring that the metal tube is in full contact with the polishing roller during the polishing process, achieving uniform and efficient polishing. For metal tubes with slightly different surface flatness, the clamping force can be adjusted to ensure that the entire tube surface can be well polished, effectively improving the polishing quality and reducing polishing defects caused by poor contact; Furthermore, as the clamping plate moves downward, the inclined clamping rod contacts the outer surface of the metal tube through the contact wheel, so that the metal tube can continue to move stably and resist the contact plate after breaking away from the contact with the cleaning conveying roller, thereby improving the accuracy of positioning.
