A special-shaped tube cold rolling forming equipment

Abstract

A kind of special-shaped pipe cold rolling forming equipment, the upper roller is connected to the lower pressing member of the upper roller, and the lower roller is connected to the upper pressing member of the lower roller. Under the driving action of the lower pressing member of the upper roller and the upper pressing member of the lower roller, the invention It has the ability to automatically adjust the position of the roll. Through the relative synchronous movement of the upper and lower rolls, it can also ensure that the center of the roll gap between the upper and lower rolls remains unchanged, and the adjustment of the roll position can be quantified through the scale. The adjustment accuracy of the roller position is guaranteed; the left and right vertical rollers matching the upper and lower rollers are installed in separately designed vertical roller installation boxes. The movement distance of the vertical roller installation boxes can be quantified through a scale, and the movement distance of the vertical roller installation boxes can be quantified directly. Ensure the position adjustment accuracy of the left and right vertical rollers; the entire roller position adjustment process is completely unaffected by human factors and no longer relies on human experience. It improves the rolling accuracy of special-shaped pipes and reduces production costs.

Description

technical field [0001] The invention belongs to the technical field of special-shaped pipe forming, and in particular relates to a special-shaped pipe cold rolling forming equipment. Background technique [0002] With the continuous development of industrial technology, the demand for special-shaped tubes in various fields is increasing, and the manufacturing and processing of special-shaped tubes also has an important impact on other fields. [0003] At this stage, there are mainly two manufacturing and processing methods for special-shaped pipes. One is to produce special-shaped pipes by cold drawing forming, that is, cold drawing forming method, and the other is to produce special-shaped pipes by cold rolling forming, that is, cold rolling forming method . For the cold drawing method, its production efficiency is low and the process is complicated, so it is becoming more and more difficult to meet the needs of special-shaped pipes in various fields.

For the cold drawing method, its production efficiency is low and the process is complicated, so it is becoming more and more difficult to meet the needs of special-shaped pipes in various fields

[0004] For the cold rolling forming method, compared with the cold rolling forming method, the production efficiency is significantly improved, and the process flow is simpler than the cold rolling forming method. However, the traditional cold rolling forming equipment used in the cold rolling forming method is still Immature, once the size of the special-shaped pipe to be processed changes, it is necessary to adjust the position of the rolls in the traditional cold rolling forming equipment, and this adjustment can only be done manually, including the adjustment of the distance between the upper and lower rolls. It is necessary to raise the lower roll. The raising process is realized by manually adding standard shims, and the raising distance is determined by combining the thickness of several standard shims, so as to realize the distance between the upper and lower rolls. The adjustment of the matching vertical roller spacing also needs to be adjusted, and the adjustment of the vertical roller spacing is all based on personal experience. It is conceivable that whether it is the upper and lower rollers or the matching vertical rollers, the spacing adjustment accuracy is seriously affected by human factors. Influence, which in turn leads to very unstable adjustment accuracy of the gap between the rollers, often resulting in low processing accuracy of special-shaped tubes, which seriously affects the qualified rate of finished products of special-shaped tubes

Furthermore, because the adjustment of the position of the rolls relies too much on human experience, it takes a lot of time and labor costs to train a certain number of technicians, and it also increases the production cost of special-shaped pipes.
