Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of stainless steel pipe production equipment, and in particular relates to a high-efficiency polishing and cutting integrated machine for stainless steel pipes. Background Technology
[0002] Stainless steel pipes, as an important industrial material, are widely used in various fields such as petroleum, chemical, construction, and machinery manufacturing. With the continuous development of industrial technology, the requirements for processing efficiency and quality of stainless steel pipes are also increasing. Traditional stainless steel pipe processing typically includes multiple steps such as conveying, polishing, and cutting.
[0003] In existing stainless steel pipe processing equipment, the conveying devices are often only suitable for stainless steel pipes of a specific diameter. Different conveying devices or complex adjustments are required for pipes of different diameters, making operation cumbersome and inefficient. Meanwhile, polishing devices typically use the pipe's own rotation to contact the polishing wheel. This method not only easily causes the pipe to deviate from the preset track, leading to decreased processing accuracy, but also often results in unsatisfactory polishing results. Furthermore, while cutting devices can cut pipes, the sharpness of the cutting blades is difficult to maintain, requiring frequent replacement or manual sharpening, increasing maintenance costs and time.
[0004] Therefore, it is essential to invent a high-efficiency polishing and cutting machine for stainless steel pipes. Utility Model Content
[0005] The purpose of this invention is to provide a high-efficiency polishing and cutting machine for stainless steel pipes, thereby solving the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model is a high-efficiency polishing and cutting integrated machine for stainless steel pipes, including a worktable, a conveyor frame, a polishing mechanism and a cutting mechanism. Several conveyor frames are arranged in a straight line on the upper side of the worktable, and each conveyor frame is fixed to the worktable by bolts. The polishing mechanism and the cutting mechanism are respectively fixed to the upper side of the worktable by bolts, and the polishing mechanism and the cutting mechanism are respectively arranged between the corresponding conveyor frames.
[0008] Furthermore, the conveyor frame includes a first frame, a lifting frame, a sliding frame, a guide column, a compression spring, a first roller, a second roller, a first motor, and a cylinder. The first frame is fixed to the workbench with bolts, and the lifting frame is slidably installed inside the first frame. The upper side of the lifting frame is connected to the first frame via a cylinder. The sliding frame is slidably installed inside the lifting frame, and a guide column is welded to the upper side of the sliding frame, through which the guide column slides. A compression spring is fitted on the outer side of the guide column and is positioned between the lifting frame and the sliding frame. The second roller is rotatably installed inside the lifting frame via a support bearing, with one end of the second roller fixed to the output end of the first motor. The base of the first motor is fixed to the lifting frame with bolts. The first roller is rotatably installed inside the sliding frame via a support bearing, and is positioned above the second roller. This configuration allows for the transport of stainless steel pipes of different diameters and ensures that the centers of the stainless steel pipes of different diameters are at the same height.
[0009] Furthermore, the polishing mechanism includes a second frame, a second motor, a first gear, a second gear, a polishing disc, and limiting wheels. The second frame is fixed to the side of the workbench with bolts, and the second motor is fixed inside the second frame with bolts. The output end of the second motor is fixed with the first gear, which meshes with the second gear. The second gear is fixed to the polishing disc by welding. Several limiting wheels mesh with the outer edge of the polishing disc, and each limiting wheel is rotatably connected to the second frame through a support bearing. The center of both the second gear and the polishing disc has a through hole. This arrangement allows for the polishing of stainless steel pipes, and because the stainless steel pipe does not need to rotate, it can prevent the stainless steel pipe from deviating from the preset track, and the polishing effect is better.
[0010] Furthermore, the polishing disc includes a disc body, a positioning plate, an electric push rod, a mounting plate, a telescopic rod, and a polishing stone. Several limiting wheels mesh with the outer edge of the disc body, and a second gear is welded to one side of the disc body. Several positioning plates are welded to the other side of the disc body, and mounting plates are mounted on the sides of the positioning plates near the center of the disc body via electric push rods. Telescopic rods are fixed between both ends of the mounting plate and the positioning plates, and a polishing stone is fixed to the other side of the mounting plate. This configuration allows for polishing of stainless steel pipes of different diameters.
[0011] Furthermore, the cutting mechanism includes a base, a fixing block, a lead screw, a third motor, a cutting blade, a fourth motor, and a whetstone. The base is fixed to the side of the workbench with bolts, and the fixing block is slidably mounted on the upper side of the base. The lead screw passes through the inside of the fixing block through threaded engagement, and both ends of the lead screw are rotatably connected to the base through support bearings. One end of the lead screw is fixed to the output end of the third motor, and the base of the third motor is fixed to the base with bolts. The cutting blade is rotatably mounted on the upper end of the fixing block, and the cutting blade is fixed to the output end of the fourth motor, the base of which is fixed to the fixing block with bolts. The cutting blade and the whetstone are fitted together, and the whetstone is fixed to the fixing block with bolts. This arrangement allows for the cutting of stainless steel pipes, and the cutting blade can be sharpened using the whetstone.
[0012] Compared with the prior art, the present invention has the following beneficial effects:
[0013] 1. The conveyor frame of this utility model can push stainless steel tubes of different diameters and ensure that the centers of stainless steel tubes of different diameters are at the same height, providing stable support and positioning for subsequent polishing and cutting processes.
[0014] 2. The polishing mechanism of this utility model allows the stainless steel tube to pass through the through hole in the center of the polishing disc under the push of the conveyor frame, without needing to rotate itself. This avoids the problem of deviating from the preset track due to rotation. In addition, the polishing stone is fixed on the polishing disc. Compared with the method of polishing by rotating the stainless steel tube, the polishing effect is more uniform and of higher quality. In particular, the polishing disc can also be adjusted by electric push rod and telescopic rod to adapt to stainless steel tubes of different diameters, further improving the versatility and flexibility of the equipment.
[0015] 3. The cutting mechanism of this utility model can drive the cutting blade to rotate through the fourth motor when it is necessary to cut the stainless steel pipe. Then, through the cooperation of the third motor and the lead screw, the fixed block slides on the base, and the rotating cutting blade cuts the stainless steel pipe. In addition, the setting of the whetstone can sharpen the cutting blade. Attached Figure Description

[0026] Please see Figure 1As shown, this utility model is a high-efficiency polishing and cutting integrated machine for stainless steel pipes, including a worktable 1, a conveyor frame 2, a polishing mechanism 3 and a cutting mechanism 4.
