Description

Technical Field

[0001] The invention relates to the field of metal processing, and in particular to a stainless steel pipe processing device and method. Background Art

[0002] The shape of stainless steel pipes is square or round. Square stainless steel pipes are stainless steel pipes with square or rectangular cross-sections. This kind of pipe is usually made of stainless steel material and has excellent corrosion resistance, high temperature resistance and mechanical strength. Square stainless steel pipes are widely used in many fields such as construction, chemical industry, petroleum, medical treatment, food, etc. In the field of construction, square stainless steel pipes are often used for decoration, handrails, railings, etc., and their unique appearance and texture can add a sense of modernity to the building. In the chemical and petroleum fields, square stainless steel pipes are used to transport various corrosive media such as acids, alkalis, salts, etc., and their excellent corrosion resistance can ensure the long-term stable operation of the pipeline. In addition, square stainless steel pipes also have good machinability and can be processed by cutting, bending, welding and other processes to meet the needs of different occasions. At the same time, the wall thickness, size and other parameters of square stainless steel pipes can be customized according to user needs, with high flexibility. It should be noted that when using square stainless steel pipes, the appropriate material and specifications should be selected according to the specific use environment and medium to ensure the safety and reliability of the pipeline. In addition, during the installation and maintenance process, attention should also be paid to comply with relevant safety regulations and operating procedures to avoid safety accidents.

This bending method causes deformation to the bending, especially for square steel pipes, which are not beautiful after bending. Therefore, when bending square pipes, the method of cutting first and then bending and welding is adopted. However, this method is very inefficient and has a low degree of automation.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

The upper end of the slider 101 is provided with a plurality of plug holes 107, and the insertion rod 106 is plugged into the plug holes 107. When the angle needs to be adjusted, the rotating rod 105 is lifted upward to disengage the insertion rod 106 from the plug hole 107, and then rotated. At this time, the rotating rod 105 and the rotating shaft 104 drive the adjusting rod 109 to rotate and adjust the angle, and then the rotating rod 105 is moved downward, and the insertion rod 106 is inserted into the corresponding plug hole 107. Through the above technical solution, the two cutting devices 1 can work alternately to efficiently cut the triangular opening, which is convenient for bending the steel pipe. The adjusting rod 109 is rotatably connected, and the angle can be adjusted through the rotating rod 105 and the inserting rod 106. The socket 107 can fix the adjusted angle to ensure that after the angle adjustment is completed, there will be no deviation during the working process to affect the final cutting angle. The lower end of the slider 101 is fixedly equipped with a matching plate 102, and the lower end of the workbench 4 is fixedly equipped with a moving motor 113. The rotating shaft of the moving motor 113 is fixedly equipped with a lead screw 114, which cooperates with the matching plate 102 to drive the cutting device 1 to move. Before placing the steel pipe on the workbench 4, first adjust the angle, slide the two sliders 101 to a position close to the clamping device 2, and then adjust the angle, and finally let the two cutting wheels 112 abut against each other, so that the lower triangle can be cut to form an opening, and then the cutting device 1 retreats and waits for bending.

[0036] In this embodiment, the clamping device 2 includes a support plate 201, which is fixedly installed on the workbench 4. A sleeve shaft 205 is rotatably mounted on the support plate 201, a torsion spring 204 is fixedly mounted between the sleeve shaft 205 and the support plate 201, a lever 206 is fixedly mounted on the lower end of the sleeve shaft 205, a center shaft 202 is rotatably mounted inside the sleeve shaft 205, a torsion spring 203 is fixedly mounted between the center shaft 202 and the sleeve shaft 205, and a lever 207 is fixedly mounted on the lower end of the center shaft 202. A vertical rod 208 is slidably installed in the shift rod 206, and a threaded rod 212 is fixedly installed on the vertical rod 208 and can be fixed to the shift rod 206 by a nut. A chuck 210 is fixedly installed at the lower end of the vertical rod 208 for clamping one end of the steel pipe.

A chuck 211 is fixedly installed on the lower side of the vertical rod 209, and the chuck 211 is used to clamp the other end of the steel pipe. In the natural state without clamping the steel pipe, the second lever 207 and the first lever 206 both rotate in the direction of the cutting device 1, and the final stopping angles are equal, and the torsion spring 1 203 and the second torsion spring 204 have the same torsion force. When in use, first adjust the positions of the vertical rod 1 208 and the second vertical rod 209 according to the length of the steel pipe so that they support the two ends of the steel pipe, and then fix them. The positions of the vertical rod 1 208 and the second vertical rod 209 relative to the second lever 207 and the first lever 206 do not change. Through the above technical solution, the second chuck 211 and the first chuck 210 can clamp the steel pipe and support the two ends of the steel pipe. Even with the action of the torsion spring 1 203 and the second torsion spring 204, the steel pipe will not move. After the steel pipe is bent, the first chuck 210 and the second chuck 211 drive the bent steel pipe to the middle position without deviating to any side, so that the fitting position at the incision is located in the middle, which is convenient for welding.

[0037] The bending device 7 includes a bending electric cylinder 701, which is fixedly installed on the workbench 4 and located at the first end of the steel pipe. An intermediate block 702 is hinged on the cylinder arm of the bending electric cylinder 701. A bending rod 703 is slidably installed on the intermediate block 702.

After the cutting is completed, the bending electric cylinder 701 is started, and the bending electric cylinder 701 drives the bending rod 703 to rotate, and the bending rod 703 pushes the steel pipe, and the steel pipe has a tendency to move as a whole. However, since the steel pipe is clamped by the clamp head 210 and the clamp head 211, and the socket 107 and the plug rod 106 can only rotate, the steel pipe can only be bent when both ends of the steel pipe are supported until the triangular opening fits, and the square steel pipe can be automatically bent and the welding is completed. After the cutting device 1 cuts, the bending device 7 can push one end of the steel pipe to bend, and the second end of the steel pipe can be kept stationary through the limit plate 6, thereby improving the bending quality of the steel pipe. At the same time, an arc groove 705 is provided on the workbench 4, and a matching shaft 704 is fixed at the lower end of the bending rod 703. When the bending rod 703 rotates, the matching shaft 704 moves in the arc groove 705. The rotation center of the bending rod 703 and the workbench 4 is also the axis of the arc groove 705.

Through the above technical solution, the welding head 307 can be welded at different positions through multiple electric cylinders, and the welding head 307 can be turned over to weld at more angles through the adjustment of the steering motor 306.

[0039] Working principle: the steel pipe is not placed on the workbench 4 first, the cutting device 1 is adjusted in angle first, the rotating rod 105 is pulled upward to rotate, the rotating rod 105 drives the rotating shaft 104 and the adjusting rod 109 to rotate, rotate to a suitable angle, press the rotating rod 105, let the insertion rod 106 and the insertion hole 107 cooperate to fix, after the angle adjustment is completed, the steel pipe is placed on the workbench 4, the middle position is located near the middle of the support plate 201, and then the nuts of the threaded rod 1 212 and the threaded rod 2 213 are loosened, the vertical rod 1 208 and the vertical rod 2 209 are slid, and the chuck 1 210 and the chuck 2 211 are supported on the steel pipe from both ends, and the chuck 1 210 and the chuck 2 211 are inserted into the steel pipe. The chuck 1 210 and the chuck 2 211 are hollow structures, and they are inserted into the steel pipe to clamp both sides of the steel pipe. After clamping, cutting is performed, and the moving motor 113 is started. The moving motor 113 drives the lead screw 114 to rotate and drive the slider 101 to move. After moving, the cutting motor 111 and the cutting electric cylinder 110 are started for cutting. The two cutting devices 1 work alternately to cut out an opening, and then the bending electric cylinder 701 is started. The bending electric cylinder 701 pushes the middle block 702, and the middle block 702 drives the bending rod 703 to rotate and push the steel pipe. The steel pipe contacts the bending rod 703, and then the steel pipe is bent from the opening. Finally, the bending electric cylinder 701 retracts, and the steel pipe is driven by the torsion spring 1 203 and the torsion spring 204 to be brought to the middle position by the clamp 1 210 and the clamp 2 211. The welding position is just in the middle of the workbench 4 and is located on the upper side of the welding device 3. Then the welding device 3 is started for welding.
