[0002] The high-precision cold rolling device for stainless steel pipe processing is a type of mechanical equipment, which is mainly used for cold-rolling stainless steel materials. When in use, the steel pipe can be cold-rolled through an annular hole of a specific diameter, which can improve the surface quality and mechanical properties of the steel pipe and meet the use requirements of more scenarios.

[0003] When cold rolling a steel pipe, a cold rolling chamber is required for auxiliary processing. Cold rolling chambers of different diameters can adapt to the processing of steel pipes of different diameters and meet more processing needs. Due to the friction between the steel pipe and the cold rolling chamber, debris from processing will remain inside the cold rolling chamber during use. Some of the debris will affect the cold rolling of the steel pipe. In severe cases, processing scratches will be left on the outer surface of the steel pipe. The staff is required to regularly flush and clean the cold rolling chamber, and the machine needs to be stopped for processing, which affects the efficiency of processing. In order to solve this technical problem, the utility model proposes a high-precision cold rolling device for stainless steel pipe processing. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

When in use, steel pipes can be placed outside the brackets 21, and the hydraulic propulsion mechanism outside the operating table 2 can control the movement of the steel pipes outside the brackets 21 to facilitate cold rolling processing.

[0023] A protection box 3 is fixedly mounted on the upper surface of the operating table 2. A through slot 20 is provided inside the protection box 3. One end of the steel pipe can be inserted into the protection box 3 through the through slot 20. The protection box 3 can shield splashes during cleaning.

[0024] A partition plate 12 is fixedly installed on the lower surface of the protective box 3, and a plurality of through holes 13 are opened inside the partition plate 12. A collecting box 14 is fixedly installed on the lower surface of the partition plate 12. By arranging components such as the collecting box 14 and the through holes 13, the liquid when cleaning the cold rolling cavity 7 can flow into the interior of the collecting box 14 through the through holes 13 for collection, which is convenient for the staff to handle.

[0025] A support rod 14 is fixedly installed inside the protective box 3, and a connecting frame 15 is slidably connected to the outer surface of the support rod 14, and a mounting frame 6 is fixedly installed on the lower surface of the connecting frame 15. A support rod 2 15 is fixedly installed inside the partition plate 12, and a connecting frame 2 16 is slidably connected to the outer surface of the support rod 2 15. The upper surface of the connecting frame 2 16 is fixedly installed with the lower surface of the mounting frame 6. The upper and lower parts of the mounting frame 6 can be stably supported by the cooperation of the upper and lower support rods 1 4 and support rods 2 15. A cold rolling cavity 7 is provided inside the mounting frame 6, and the steel pipe can be cold-rolled by the cold rolling cavity 7. The support of the support rods 1 4 and 15 can ensure the overall stability of the steel pipe during cold rolling.

[0026] A tooth plate 8 is fixedly installed on one side of the mounting frame 6, and the outer part of the tooth plate 8 is meshed with a gear 9. The mounting frame 6 and the tooth plate 8 are each provided with two groups and are symmetrically arranged. The movement of the tooth plate 8 can be controlled by the rotation of the gear 9. At this time, the tooth plate 8 can drive the two groups of mounting frames 6 to move in the opposite direction. When one group of mounting frames 6 is undergoing cold rolling processing, the other group of mounting frames 6 can move to the depth of the protective box 3.

[0027] The inner wall of the protective box 3 is fixedly installed with multiple groups of support plates 17, and the internal rotation of the support plate 17 is connected with a fixed shaft 18. The outer surface of the fixed shaft 18 is fixedly installed inside the gear 9. A group of tooth plates 8 can control the movement of two groups of tooth plates 8.

[0030] When in use, the gear 9 can control the movement of the tooth plate 8, and can control a group of mounting frames 6 to move to the position of the through groove 20. At this time, the steel pipe can be cold rolled through the cooperation of the mounting frames 6 and the cold rolling chamber 7. When the gear 9 rotates, another group of mounting frames 6 can move to the depth of the protective box 3. At this time, multiple groups of high-pressure nozzles 11 can perform high-pressure flushing on the cold rolling chamber 7 without stopping the machine. When the tooth plate 8 moves, the mounting frame 6 can slide on the outside of the support rod 1 4 and the support rod 2 15.
