Description

Technical Field

[0001] The invention relates to the technical field of grinding equipment, in particular to an end grinding equipment for a stainless steel pipe. Background Art

[0002] During the period from the production of stainless steel pipes to the use, the stainless steel pipes will inevitably be exposed to the air, and the surface of the stainless steel pipes will be oxidized by the air, so that a layer of oxide will form on the surface of the stainless steel pipes. When the stainless steel pipes need to be welded, the oxides on the surface will lead to poor welding effect, resulting in the instability of the stainless steel pipe joints and reducing the structural stability of the stainless steel pipes. Therefore, before welding the stainless steel pipes, it is generally necessary to grind the surface of the stainless steel ends to remove the oxides on the surface.

[0003] The commonly used method of grinding stainless steel pipes is to grind the stainless steel pipes with handheld angle grinders. This method requires the stainless steel pipes to be fixed before grinding. The operation is cumbersome, and manual grinding with handheld angle grinders will result in uneven grinding, affecting the quality of the stainless steel pipes.

[0004] Chinese patent CN117817525A discloses a stainless steel pipe end grinding device, including a support ring, a motor is arranged inside the support ring, a first mounting block is fixedly installed on the shaft end of the motor, a slide rod is fixedly inserted at both ends of the first mounting block, two slide rods are slidably connected to support seats at both ends, a grinding wheel is rotatably connected to the top of the support seat; a tightening mechanism is arranged between the two grinding wheels, the tightening mechanism includes a slide rail, the bottom of the slide rail is fixedly installed on the top of the first mounting block, and two second sliders are slidably connected to the slide rail. The device drives the rubber pad to clamp by inserting the stainless steel pipe, which is convenient for fixing the stainless steel pipe. At the same time, the stainless steel pipe drives the second slider to open, so that the first spring pulls the grinding wheel against the stainless steel pipe, which is convenient for grinding, simple to operate, does not require additional manual fixation, and the grinding is relatively uniform.

[0005] Although the above-mentioned Chinese patent has achieved the goal of clamping the rubber pad by inserting the stainless steel tube to facilitate the fixing of the stainless steel tube, and at the same time the stainless steel tube drives the second slider to open, so that the first spring pulls the grinding wheel against the stainless steel tube, which is convenient for grinding, simple to operate, does not require additional manual fixation, and the grinding is relatively uniform; however, the device lacks a grinding block feeding structure, and the wear and tear of the grinding block is relatively large in actual grinding operations, and the frequency of replacement of the grinding block is relatively high in large-scale grinding operations.

Then the user powers on the servo motor 402 and rotates the position of the idle docking seat 405 to align with the guide seat 522. When the idle docking seat 405 reaches the specified position, it squeezes the trigger rod 525, so that the output electrode seat 528 at the bottom of the trigger rod 525 moves downward and contacts the input electrode seat 526, thereby connecting the output wire 529 to the input wire 527 and energizing the drive cylinder 513.
