Description

Technical Field

[0001] The present application relates to the technical field of surface treatment of stainless steel pipes, and in particular to a surface polishing machine for stainless steel pipes. Background Art

[0002] Stainless steel pipes are steel pipes made from steel billets through a series of processes. They are mainly used in the transportation of various gas or fluid media. Before processing, the surface of stainless steel pipes may often be rusted or have some attachments, so the surface of the stainless steel billet needs to be polished and cleaned for further processing.

[0003] At present, for the grinding and polishing of steel billets, a relatively light and movable polishing machine is used to move back and forth to process the outer surface of the steel billet. However, the polishing is limited to a local side of the steel billet. After completing a reciprocating polishing, the steel billet needs to be rotated multiple times to complete the grinding of the outer surface of the entire steel billet, which is more troublesome to operate. Utility Model Content

[0004] In order to improve the efficiency of polishing and grinding, the purpose of this application is to provide a surface polishing machine for stainless steel pipes.

[0005] A surface polishing machine for stainless steel pipes, comprising a frame, the frame being provided with a polishing device for polishing a steel billet and a clamping device for clamping the steel billet, the polishing device comprising an inner polishing mechanism and an outer polishing mechanism for simultaneously polishing both sides of the steel billet;

[0006] The inner polishing mechanism comprises an inner polishing belt, an inner roller group around which the inner polishing belt is wound, and an inner bracket rotatably connected to the inner roller group, wherein the inner bracket is provided with an inner driving member for driving the inner polishing belt;

[0007] The external polishing mechanism comprises an external polishing belt, an external roller group for the external polishing belt to be wound around, and an external bracket for the external roller group to be rotatably connected, wherein the external bracket is provided with an external driving member for driving the external polishing belt;

[0008] The frame is also provided with an opening and closing device for driving the inner polishing mechanism and the outer polishing mechanism to move closer to or apart from each other, and a moving device for driving the opening and closing device to move.

[0009] By adopting the above technical scheme, the clamping device stably clamps and fixes the steel billet, and the polishing device polishes the steel billet. Since the outer polishing mechanism and the inner polishing mechanism operate simultaneously, the steel billet can be polished and ground from both sides at the same time, which significantly improves the polishing efficiency. Secondly, the inner polishing belt and the outer polishing belt on both sides are relatively arranged, so that the grinding debris generated during polishing can be relatively concentrated in the middle, reducing dust pollution, so that the subsequent dust collection treatment is also more time-saving. The opening and closing device can control the relative movement of the outer polishing mechanism and the inner polishing mechanism. After the opening and closing device is unfolded, it is convenient to put the steel billet in. The entire opening and closing device moves with the moving device, so that the outer polishing mechanism and the inner polishing mechanism can complete the polishing along the axial direction of the steel billet, and the multi-point polishing is uniform. The steel billet can be polished as a whole with fewer rotations.

[0010] Optionally, the clamping device includes a main support, a secondary support, and a clamping sliding mechanism that drives the secondary support to slide. The main support is rotatably connected to a stepped internal support member, and the frame is provided with an internal support rotating mechanism that drives the stepped internal support member to rotate.

[0011] By adopting the above technical scheme, the clamping device is divided into multiple parts. The stepped internal support member has stepped steps. The internal support member can be inserted into the steel billet to support the steel billet from the inside, so that the steel billet can obtain a better support effect. The auxiliary support can support the steel billet through a similar structure. At the same time, according to the different lengths of the steel billet, the clamping sliding mechanism can adjust the position of the auxiliary support. During the polishing process, the internal support rotation mechanism can drive the main support to rotate, thereby realizing the rotation of the steel billet, and can complete multi-sided polishing more efficiently.

[0012] Optionally, there are two main supports, and bearings are provided in both main supports. The inner support has a central axis that penetrates into the bearing, and one end of the central axis is driven by the inner support rotation mechanism.

[0013] By adopting the above technical solution, the two main supports make the central axis rotate smoothly, and the inner support rotation mechanism drives the inner support member to rotate relatively smoothly through the central axis. Optionally, the opening and closing device includes two vertical rods, the outer polishing mechanism and the inner polishing mechanism are respectively hinged on the two vertical rods, and the opening and closing device also includes a hydraulic cylinder, a synchronous member connected by the piston rod of the hydraulic cylinder, and a connecting rod hinged on both sides of the synchronous member, and the two connecting rods are respectively hinged to the rotation eccentric points of the outer polishing mechanism and the inner polishing mechanism.

[0014] By adopting the above technical solution, the two vertical poles are used to support and rotate the outer polishing mechanism and the inner polishing mechanism respectively. The hydraulic cylinder serves as a power source to drive the synchronous part to move, the synchronous part drives the connecting rod to rotate, and the connecting rod then drives the outer polishing mechanism and the inner polishing mechanism synchronously. Since the two actions share one hydraulic cylinder, the actions can be synchronized and the use of the driving source is reduced.

[0015] Optionally, the moving device includes a moving plate and moving wheels connected to the bottom side of the moving plate.

[0016] By adopting the above technical solution, the entire moving device slides through the moving wheels, and the movement is smoother.

[0017] Optionally, the moving device includes two groups of moving disks rotatably connected to a frame, a moving belt wound around the two groups of moving disks, and a moving motor driving the moving belt for transmission.

[0018] By adopting the above technical solution, the movement of the moving device is mainly driven by the moving belt. Even if the moving device vibrates, the moving belt can absorb energy appropriately to avoid the rigidity damage of the transmission part.

[0019] Optionally, the frame is provided with two sets of slide rails for the movable wheels to slide, and the two sets of slide rails are connected vertically.

[0020] By adopting the above technical solution, the slide rail is used to guide and limit the movement of the mobile device, thereby reducing the movement deviation of the mobile device.

[0021] Optionally, a dust collection box is provided on the bottom side of the frame along the length direction.

[0022] By adopting the above technical solution, the dust collecting box can directly collect the debris under the polishing device, and can be sucked away for treatment after polishing is completed, thereby reducing dust pollution.

[0023] In summary, this application includes the following technical effects:

[0024] 1. The polishing device polishes both sides simultaneously, and combines the moving device and the internal support rotation mechanism to achieve efficient polishing processing;

[0025] 2. The polishing surface is on the inner side of the enclosure, which can reduce dust and is collected by the dust box. BRIEF DESCRIPTION OF THE DRAWINGS
