Description

Technical Field

[0001] The utility model relates to the technical field of chamfering devices, in particular to a chamfering device for a stainless steel welded pipe. Background Art

[0002] The chamfering machine is a small precision machine tool specially used for chamfering metal objects and removing burrs of products processed by milling, planing and other processing methods.

[0003] During the processing of the stainless steel welded pipe, the stainless steel welded pipe is brought into contact with the cutter on the chamfering machine, and the stainless steel welded pipe is cut by the cutter to complete the chamfering of the stainless steel welded pipe.

[0004] In the prior art, when chamfering a stainless steel welded pipe, the stainless steel is placed on a chamfering machine, the position of the stainless steel welded pipe is positioned, and then clamped. At this time, the chamfer can be performed by a cutter. However, in the prior art, the position of the stainless steel welded pipe needs to be positioned before chamfering. After the position of the stainless steel welded pipe is positioned, it is clamped and fixed, and then processed to ensure cutting accuracy. However, the length of the stainless steel welded pipe after cutting is inconsistent, and manual positioning is required to ensure that the length of the stainless steel welded pipe after processing is consistent. However, errors may occur due to manual positioning. Therefore, we propose a chamfering device for stainless steel welded pipes. Utility Model Content

[0025] The extrusion unit includes a sliding seat 6 and a plurality of extrusion seats 601. The extrusion seat 601 is fixedly connected to the outer wall of the sliding seat 6. The extrusion seat 601 fits with the inner wall of the stainless steel welded pipe 4. The extrusion unit extrudes the stainless steel welded pipe 4 through the extrusion seat 601. The extrusion seat 601 fits with the inner wall of the stainless steel welded pipe 4. Under the action of the plurality of extrusion seats 601, the stainless steel welded pipe 4 is positioned. The extrusion seat 601 is convenient for fixing stainless steel welded pipes 4 of different sizes. The stainless steel welded pipe 4 is pushed and extruded by the sliding seat 6 and the extrusion seat 601, so that the stainless steel welded pipe 4 contacts the cutter for chamfering.

[0026] The positioning unit includes a threaded rod 801, which is arranged on a fixed seat 5. A positioning seat 802 is threadedly connected to the threaded rod 801. The positioning unit limits the position of the sliding seat 6 through the positioning seat 802. By limiting the position of the sliding seat 6, the moving distance of the stainless steel welded pipe 4 is limited, which is convenient for cutting stainless steel welded pipes 4 of different lengths and processing the stainless steel welded pipe 4 into a qualified length, avoiding the need to accurately position the stainless steel welded pipe 4 before processing, thereby achieving the effect of ensuring its processing accuracy and reducing processing efficiency;

[0027] By rotating the positioning seat 802 on the threaded rod 801 , the positioning seat 802 moves along the threaded rod 801 , so that the positioning seat 802 is at a specified position. Under the action of the positioning seat 802 , the position of the sliding seat 6 is limited.

[0028] A cutter is drivingly connected to the cutting machine 2 , and the end of the stainless steel welded pipe 4 contacts the cutter. The stainless steel welded pipe 4 is chamfered by the contact between the cutter and the stainless steel welded pipe 4 .

[0029] The top end surface of the fixed seat 5 is fixedly connected to a connecting seat 501, and a fixing rod 502 is fixedly connected to the connecting seat 501. The end of the fixing rod 502 away from the connecting seat 501 is fixedly connected to the chamfering machine 1.
