Technical Field
The invention relates to the technical field of cooling water pipe manufacturing, in particular to a method for manufacturing a cooling water pipe of a roller in multi-wire splitting rolling.
Background
At present, the roller cooling water pipe is mostly welded by staff in the multi-line segmentation process, the actual use effect after processing is unstable, the crookedness of cooling water pipe is inconsistent with the crookedness of roller, causes the cooling effect to the roller relatively poor, and the result is exactly that often appears in the production process because the roller cooling effect is poor, leads to the roller wearing and tearing serious, does not reach the rolling volume and rolls off the production line in advance, has restricted the normal operating of production.
Disclosure of Invention
In order to solve the defects and defects of the prior art, the invention provides the method for manufacturing the cooling water pipe of the roller in the multi-wire splitting rolling, so that the manufactured cooling water pipe is consistent with the curvature of the roller, can be fully attached to the surface of the roller, is fully cooled, and is more stable in online service life, and simultaneously, as the hole patterns in the splitting process are uniformly worn, the negative difference and the line difference in the splitting rolling are easier to control.
The technical scheme adopted for solving the technical problem is as follows:
a method for manufacturing a cooling water pipe of a roller in multi-wire splitting rolling comprises the following steps:
a. manufacturing a cooling water pipe bending standard sample: manufacturing a cooling water pipe bending standard sample with the same curvature as the roller according to the diameter and the length of the roller in the multi-line splitting rolling;
b. manufacturing a single cooling water pipe: heating the processed single cooling water pipe, and then bending the cooling water pipe along a standard cooling water pipe sample to enable the bending degree of the cooling water pipe to be consistent with that of the roller;
c. manufacturing a plurality of cooling water pipes: repeating the step b, and manufacturing cooling water pipes with the same number as that of the rollers;
d. manufacturing a plurality of cooling water pipes to align the standard sample: manufacturing a cooling water pipe alignment standard sample with the same distance with the rolling groove according to the distance between the rolling grooves in the multi-line splitting rolling;
e. manufacturing a cooling water pipe of a middle roller for multi-line splitting rolling: and (3) welding the cooling water pipes according to the alignment standard of the plurality of cooling water pipes, so that the distance between the cooling water pipes is the same as the distance between the grooves.
Further, the structure of the cooling water pipe bending standard sample in the step a is a cylindrical structure, an annular groove is formed in the outer wall of the cylindrical structure, and the inner diameter of the annular groove is the same as the diameter of the roller; and d, the structure of the cooling water pipe alignment standard sample in the step d is a square structure, a plurality of grooves are arranged on the side edge of the square structure, the diameter of each groove is the same as that of the cooling water pipe, and the distance between every two grooves is the same as that between every two rolling grooves.
The invention has the beneficial effects that: according to the invention, the cooling water pipe standard sample and the cooling water pipe alignment standard sample are manufactured, the cooling water pipe is manufactured through the cooling water pipe standard sample, the curvatures of the cooling water pipe and the roller can be consistent, the cooling water pipe can be fully attached to the surface of the roller for fully cooling, the cooling water pipe is aligned to the standard sample, the cooling water pipe suitable for the roller in multi-line splitting rolling is manufactured, the distance between the cooling water pipes is ensured to be the same as the distance between rolling grooves, each roller can be fully cooled, the online service life of the roller is more stable, and simultaneously, as the groove patterns in the splitting process are uniformly worn, the negative difference and the line difference in the splitting rolling are more easily controlled.
