Description

Technical Field

[0001] The utility model relates to the technical field of roll grinders, in particular to a magnetic force regulating device for a cold-rolled steel pipe roll grinder. Background Art

[0002] The magnetic adjustment device of the cold-rolled steel pipe roll grinder mainly relates to the field of roll grinder devices, especially for the accuracy and efficiency of roll grinding in the cold-rolled steel pipe processing process. The device adopts a magnetic rail structure to achieve faster and quieter adjustment to meet the high precision and high efficiency requirements of roll grinding in the cold-rolled steel pipe processing.

[0003] According to a patent application published online (authorization publication number CN219311018 U), a magnetic force adjustment device for a cold-rolled steel tube roll grinder is described as follows: "A magnetic force adjustment device for a cold-rolled steel tube roll grinder includes a processing grinder, which includes a grinding bed, an adjustment support bed, and a push support bed aligned axially from front to back. The front portion of the cold-rolled steel tube extends into the grinding bed, and the middle portion is mounted on the adjustment support bed. The rear portion of the cold-rolled steel tube is connected to the push support bed and is driven by the push support bed to move forward and backward. The adjustment support bed includes a sliding plate, a lifting roller, a magnetic rail, and a push block."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During use of the utility model, when the height of the lifting roller needs to be adjusted, the device adjusts the magnetic force of the magnetic rail on one side to offset the cold-rolled steel pipe to the other direction, and all the magnetic rails can be adjusted to lift the cold-rolled steel pipe. However, in actual use, the device only lifts the cold-rolled steel pipe through the lifting roller, and when the cold-rolled steel pipe is pushed into the grinding bed by pushing the support bed at a later stage, the lifting is only completed by the lifting roller during the pushing process, so that the cold-rolled steel pipe cannot better support the weight of the cold-rolled steel pipe during the pushing process, which makes it easy to increase vibration and offset during the grinding process. Therefore, it is necessary to improve a magnetic force adjustment device for a cold-rolled steel pipe roller grinder. Utility Model Content
