[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0026] First Embodiment
[0027] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the first embodiment of the end bevel processing device for stainless steel welded pipe provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the polishing device. Figure 3 for Figure 2 The diagram shows the structure of the rounded corner component. Figure 4 for Figure 1 The enlarged schematic diagram at point A is shown. An apparatus for processing the beveled ends of stainless steel welded pipes includes: a worktable 1;
[0028] Mounting bracket 2 is fixedly installed on one side of the top of the workbench 1. A grinding device 3 is fixedly installed inside the mounting bracket 2. The grinding device 3 includes a first hydraulic cylinder 31, a mounting box 32, a servo motor 33, a connecting column 34, a grinding column 35, and a rounded corner grinding component 36.
[0029] The rounded corner component 36 includes a mounting ring block 361 and a chamfered bevel 362.
[0030] The first hydraulic cylinder 31 is fixedly installed at the top inside the mounting bracket 2. The mounting box 32 is fixedly installed at the output shaft end of the first hydraulic cylinder 31. The servo motor 33 is fixedly installed in the middle of one side of the mounting box 32. The connecting column 34 is disposed at one end of the output shaft of the servo motor 33. A plurality of grinding columns 35 are stacked and fixedly installed in the middle of the surface of the connecting column 34. The rounded corner component 36 is fixedly installed on one side of the outer surface of the grinding column 35.
[0031] The mounting ring block 361 is fixedly installed on one side of the outer surface of the grinding column 35, and the chamfered bevel 362 is provided on the outer surface of the mounting ring block 361.
[0032] A movable clamp 5 is slidably installed at the top center of the workbench 1. A connecting plate 6 is fixedly installed on one side of the outer surface of the movable clamp 5. A second hydraulic cylinder 7 is fixedly installed on both sides of the top of the connecting plate 6. A guide plate 8 is fixedly connected to the top of the output shaft of the second hydraulic cylinder 7.
[0033] A collection rack 4 is fixedly installed on one side of the outer surface of the workbench 1.
[0034] There are two grinding pillars 35. The smaller diameter one is fixedly installed in the middle of the surface of the larger diameter grinding pillar 35. Multiple pillars can be stacked in this way. The mounting ring block 361 is installed on the outer surface of the grinding pillar 35 and fits against the surface of the other grinding pillar 35. After the welding pipe is sleeved on the outer surface of the grinding pillar 35, the end of the inner wall of the welding pipe fits against the chamfered bevel surface 362 of the mounting ring block 361.
[0035] The moving clamp 5 uses a motor, a reciprocating screw, and a guide plate to restrict the two clamping blocks to move closer or further apart, thereby clamping and fixing the welded pipe.
[0036] The connecting plate 6 is connected to the movable clamp 5. The movable clamp 5 moves, causing the guide plate 8 to move, so that the guide plate 8 is kept at the bottom in the middle of the outer surface of the welded pipe. The output axis of the second hydraulic cylinder 7 moves upward to push the guide plate 8 to rise. The guide plate 8 lifts the welded pipe and guides the welded pipe to slide into the inside of the collection rack 4 for collection and storage.
[0037] The working principle of the end bevel processing device for stainless steel welded pipes provided by this utility model is as follows:
[0038] During operation, the clamp 5 is first moved to hold the welded pipe, and the output shaft of the first hydraulic cylinder 31 moves to push the grinding device 3 to the end of the welded pipe, so that the welded pipe is sleeved on the outer surface of the grinding column 35 of the corresponding diameter through the pipe cavity, and the end of the welded pipe cavity and the mounting ring block 361 are close to each other.
[0039] The output shaft of the servo motor 33 rotates to drive the grinding column 35 and the rounded corner grinding component 36 to rotate. The grinding column 35 grinds the surface of the inner wall of the pipe, and the mounting ring block 361 bevels and grinds the end of the inner wall of the pipe through the chamfered bevel 362, so that the end of the inner wall of the pipe is beveled.
[0040] Compared with related technologies, the end bevel processing device for stainless steel welded pipes provided by this utility model has the following advantages:
[0041] This utility model provides a device for processing the beveled ends of stainless steel welded pipes. Multiple grinding columns 35 are stacked and installed, accommodating stainless steel welded pipes of various diameters. The pipes are mounted on the outer surface of the grinding columns 35 with corresponding diameters. An installation ring 361 grinds the inner wall of the stainless steel welded pipe end using a chamfered bevel 362, resulting in a smooth end and a beveled inner wall. This device has a simple structure, high practicality, and can grind welded pipes of various diameters, improving the practicality and flexibility of the processing device and reducing the cost of purchasing such equipment for enterprises.

[0045] Limiting holes 10 are provided around the outer surface of the connecting column 34.
[0046] The working principle of the end bevel processing device for stainless steel welded pipes provided by this utility model is as follows:
[0047] During operation, the connecting post 34 is first installed in the middle of the surface of the mounting plate 9. The four screws 13 on the surface of the mounting plate 9 are rotated through the threaded holes 12 and embedded into the limiting holes 10 on the surface of the connecting post 34 to restrict the installation of the connecting post 34.
[0048] During disassembly, simply rotate the screw 13 in the opposite direction to engage the threaded hole 12, and it will exit from the inside of the limiting hole 10.
[0049] Compared with related technologies, the end bevel processing device for stainless steel welded pipes provided by this utility model has the following advantages:
