Large-taper tank edge rolling forming technology adopting four-core edge rolling machine

Abstract

The invention relates to the field of machine manufacturing, in particular to a large-taper tank edge rolling forming technology adopting a four-core edge rolling machine. The large-taper tank edge rolling forming technology aims to solve the problem that when a large-taper tank edge rolling technology is conducted on a four-core edge rolling machine, deflection is likely to happen. According to the large-taper tank edge rolling forming technology, two sets of guiding wheel stops and one set of feeding wheel stops are additionally arranged on supports arranged at the two ends of a roller of a plate rolling machine so that the deflection force existing during large-taper tank plate rolling can be limited or counteracted. On the basis of an existing device, the transformation cost of the device is low, the structure is simple, and the transformation period is short. By the adoption of the large-taper tank edge rolling forming technology utilizing the four-core edge rolling machine, it can be effectively guaranteed that development work of a novel railway cement tanker of 80 t can be completed within a short time.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a large-taper can body rolling forming process using a four-core rolling machine. Background technique [0002] The U80 cement tanker is a new 80t-class cement tanker of the National Railways. In order to reduce the center of gravity of the vehicle and facilitate the unloading of goods, the tank body adopts a large taper (the taper is 9°) design. This design structure is quite different from the previous design. There is no way to learn from the process. Therefore, the manufacture of the large-taper tank body is the main process difficulty in the development of the U80 cement tanker. [0003] The forming technology of existing conical tank mainly adopts three-core rolling rod or four-core rolling rod to form. During the rolling process of the three-core rolling machine, since the axis lines between the rolls are parallel to each other and are fixed, in the process of roll...

AI Technical Summary

Problems solved by technology

[0005] The present invention mainly solves the cumbersome adjustment of the three-core roll rolling operation, poor precision, and difficulty in controlling and mastering existing in the prior art, and is not suitable for rolling a tapered cylinder. The technical problems of rolling; provide a large-tapered tank body rolling forming process based on the existing equipment, using a four-core rolling machine, the cost of equipment transformation is low, the structure is simple, and the cycle is short. In a relatively short period of time, the trial production of 80t-class new cement tank cars for railways was completed, and the large-tapered tank body rolling forming process using a four-core rolling machine to solve the large-tapered tank body forming process was completed.
