Description

Technical Field

[0001] The present invention relates to the technical field of iron chip cleaning of chamfering machines, and particularly relates to an iron chip cleaning device for a spiral steel pipe chamfering machine. Background Art

[0002] Spiral steel pipes are made of strip steel coils as raw materials, formed by cold extrusion at room temperature, and welded by an automatic double-wire double-sided submerged arc welding process. The production of spiral steel pipes is to feed the strip steel into the welded pipe unit, and after being rolled by multiple sets of rollers, the strip steel gradually rolls up to form a circular pipe blank with an opening gap. Adjust the reduction of the extrusion rollers to control the weld gap within 1 - 3 mm and make the two ends of the weld flush. The steel pipe chamfering machine is used to chamfer and bevel the welding bevels at both ends of the steel pipe as required. The steel pipe chamfering machine is a double-head chamfering machine, equipped with a headstock, a faceplate, a clamping device, a hydraulic auxiliary fixture, a lifting roller table device, etc. To solve the problem of the pipe ends of thick-walled steel pipes during processing, two chamfering knives and a facing tool are configured on the faceplate of the steel pipe chamfering machine. Spiral steel pipe chamfering is a process in the production process and has a greater impact on the appearance of the steel pipe.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] Refer to Figures 1-9 , a chip cleaning device for a spiral steel pipe chamfering machine provided by the present invention includes a base 1. A driving mechanism 2 is arranged at the upper end of the base 1, and a spiral steel pipe body 9 is arranged inside the driving mechanism 2; an adjusting mechanism 3 and a lifting mechanism 5 are arranged inside the base 1. The lifting mechanism 5 is used to lift the spiral steel pipe body 9. An internal cleaning mechanism 4 is arranged at the side end of the adjusting mechanism 3, and the internal cleaning mechanism 4 is used to clean the chips inside the spiral steel pipe body 9; an external cleaning mechanism 6 is arranged at the rear end of the adjusting mechanism 3, and the external cleaning mechanism 6 is used to clean the outside of the pipe orifice of the spiral steel pipe body 9.

[0036] During use, transfer the spiral steel pipe guided by the chamfering machine to the driving mechanism 2, then use the lifting mechanism 5 to lift the spiral steel pipe on the driving mechanism 2. Next, the internal cleaning mechanism 4 works, making the cleaning end lower than the lower end of the spiral steel pipe. In this way, it is convenient to use the adjusting mechanism 3 to drive the internal cleaning mechanism 4 to achieve the centering adjustment of the spiral steel pipe. After the cleaning end of the internal cleaning mechanism 4 is lower than the lower end of the spiral steel pipe, at this time, the adjusting mechanism 3 works, and it can drive the two internal cleaning mechanisms 4 to move towards each other, so that the centering adjustment of the spiral steel pipe can be achieved; after the adjustment is completed, the lifting mechanism 5 descends, causing the spiral steel pipe to fall under the action of gravity and then land on the upper end of the driving mechanism 2. After the spiral steel pipe lands on the upper end of the driving mechanism 2, at this time, the adjusting mechanism 3 works in the reverse direction, and it can drive the two internal cleaning mechanisms 4 away from the spiral steel pipe; then the internal cleaning mechanism 4 works in the reverse direction, making the cleaning end higher than the inner wall of the lower end of the spiral steel pipe, so that it is convenient for the internal cleaning mechanism 4 to enter the spiral steel pipe. After the internal cleaning mechanism 4 enters the spiral steel pipe for a certain distance, at this time, the external cleaning mechanism 6 is exactly located at the rear side of the pipe orifice of the spiral steel pipe, and at this time, it is convenient for the external cleaning mechanism 6 to clean the outside of the pipe orifice of the spiral steel pipe; when cleaning the outside of the pipe orifice of the spiral steel pipe, the driving mechanism 2 works, and at this time, it can drive the spiral steel pipe to rotate. As the spiral steel pipe rotates, the cleaning of the pipe orifice of the spiral steel pipe can be achieved; when cleaning the outside of the pipe orifice of the spiral steel pipe, the flying iron filings will enter the inside of the spiral steel pipe, and then the internal cleaning mechanism 4 will clean the iron filings inside the spiral steel pipe, so that manual cleaning by workers is not required during the cleaning of the iron filings, thereby reducing the harm to workers.

[0037] The driving mechanism 2 includes a support plate 201, a support roller 202, a support frame 203, a first hydraulic telescopic rod 204, a guide rod 205, a first mounting frame 206, a first motor 207 and a power roller 208. Both sides of the upper end of the base 1 are fixedly connected with a support plate 201. A support roller 202 is rotatably connected inside the support plate 201.

The extending end of the first hydraulic telescopic rod 204 is fixedly connected with a first mounting frame 206. A power roller 208 is rotatably connected inside the first mounting frame 206. The side end of the first mounting frame 206 is fixedly connected with a first motor 207. The output end of the first motor 207 is fixedly connected with the power roller 208. The upper end of the first mounting frame 206 is fixedly connected with a guide rod 205. The upper end of the guide rod 205 penetrates through the support frame 203 and is slidably connected with the support frame 203. During work, the first hydraulic telescopic rod 204 extends. At this time, with the cooperation of the guide rod 205, the first mounting frame 206 can be driven to move down stably, thereby driving the power roller 208 to contact the spiral steel pipe. After the power roller 208 contacts the spiral steel pipe, at this time the first motor 207 works, which can drive the power roller 208 to rotate. Then, with the cooperation of the support roller 202, the spiral steel pipe can be driven to rotate, so as to facilitate the cleaning work around the pipe orifice of the spiral steel pipe.

During work, when centering the placed spiral steel pipe, the second hydraulic telescopic rod 501 works. At this time, the moving frame 502 can be driven to move. When the moving frame 502 moves upward, at this time, with the cooperation of the second mounting frame 503, the rotating roller 504 can be driven to move upward, so that the rotating roller 504 contacts the spiral steel pipe. After the rotating roller 504 contacts the spiral steel pipe, at this time the second hydraulic telescopic rod 501 continues to move upward, which can drive the lower end of the spiral steel pipe away from the support roller 202, so as to facilitate the left and right movement of the spiral steel pipe, thereby facilitating the centering adjustment of the spiral steel pipe.

[0039] The adjusting mechanism 3 includes an L-shaped rod 301, a second motor 302, and a bidirectional threaded rod 303. The bidirectional threaded rod 303 is rotatably connected inside the base 1.

During operation, after the spiral steel pipe moves away from the support roller 202, the second motor 302 works. With the cooperation of the bidirectional threaded rod 303, the L-shaped rod 301 can be driven to move. Furthermore, with the cooperation of the internal cleaning mechanism 4, it is convenient to drive the spiral steel pipe to move, thereby realizing the centering adjustment of the spiral steel pipe.

[0040] A square hole 7 is formed on the upper end surface of the base 1. The L-shaped rod 301 is located inside the square hole 7 and is slidably connected to the square hole 7. During operation, by providing the square hole 7, the movement of the L-shaped rod 301 can be facilitated with the cooperation of the square hole 7.

[0041] The internal cleaning mechanism 4 includes a disc 401, a square frame 402, a third motor 403, a moving frame 404, a lead screw 405, a slider 406, and a scraper 407.

After the scraper 407 contacts the inner wall of the spiral steel pipe, the inside of the spiral steel pipe can be cleaned by using the scraper 407. When the lower end of the scraper 407 is lower than the lower end of the spiral steel pipe, it is convenient to drive the spiral steel pipe to move, thus facilitating the centering adjustment.

[0042] The external cleaning mechanism 6 includes a moving plate 601, a support column 602, a third hydraulic telescopic rod 603 and a wire brush 604. The rear end of the L-shaped rod 301 is fixedly connected to the moving plate 601. The upper end of the moving plate 601 is fixedly connected to the support column 602.

During operation, as the L-shaped rod 301 moves, the support column 602 is also driven to move with the cooperation of the moving plate 601, which is beneficial for the wire brush 604 to be directly behind the pipe orifice of the spiral steel pipe. When the wire brush 604 is directly behind the pipe orifice of the spiral steel pipe, the third hydraulic telescopic rod 603 extends, driving the wire brush 604 to approach the spiral steel pipe. After the wire brush 604 contacts the spiral steel pipe, it is convenient to clean the outside of the pipe orifice of the spiral steel pipe.
