Reinforcing roller and manufacturing method thereof

Abstract

The invention discloses a reinforcing roller and a manufacturing method thereof. The reinforcing roller comprises a roller body and roller shafts arranged at the two ends of the roller body; the roller body comprises a plurality of roller sections, and roller section connecting pieces used for connecting the adjacent roller sections; the roller sections comprise roller section outer pipes, a plurality of roller section axial rib plates are evenly arranged on the inner walls of the roller section outer pipes, and the length of the roller section axial rib plates is less than that of the rollersection outer pipes; the roller section connecting pieces comprise connecting piece outer pipes mounted in the adjacent roller section outer pipes in an inserted mode, the connecting piece outer pipesare arranged between the adjacent roller section axial rib plates, and the adjacent roller section outer pipes are fixedly connected. The manufacturing method of the reinforcing roller comprises thefollowing steps that the roller sections are machined; the roller section connecting pieces are machined; the roller sections are assembled; the roller shafts are machined and mounted; and an outer sleeve is mounted. The reinforcing roller is simple in structure, small in weight, and high in supporting strength, a required driving roller is low in energy consumption, machining and mounting are convenient and quick, and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a reinforcing roller and a manufacturing method thereof, belonging to the technical field of roller processing. Background technique [0002] Due to the long body length of the existing elongated rollers, it is difficult to process and manufacture, and the production cost is high. However, the supporting strength of the processed long rollers is not enough, and bending is prone to occur. In order to ensure the supporting strength of the roller body, the general It will increase the thickness of the roller body. Although the thickening of the roller body improves the support strength of the roller body, it leads to excessive wall thickness of the roller body, increased self-weight, and increased material and processing costs. When the roller body is used, the power consumption of driving the roller body The energy is high, and the radial runout of the roller body is large, which will eventually affect the rotation of the guide r...

[0002] Due to the long body length of the existing elongated rollers, it is difficult to process and manufacture, and the production cost is high. However, the supporting strength of the processed long rollers is not enough, and bending is prone to occur. In order to ensure the supporting strength of the roller body, the general It will increase the thickness of the roller body. Although the thickening of the roller body improves the support strength of the roller body, it leads to excessive wall thickness of the roller body, increased self-weight, and increased material and processing costs. When the roller body is used, the power consumption of driving the roller body High energy, large radial runout of the roller body, which will eventually affect the rotation of the guide roller

In addition, when processing the inside of the longer roll section, due to the limited roll diameter, the welding operation is difficult, especially when the length is more than two meters, the internal reinforcement welding is generally carried out by a long rod with a welding torch. Due to human factors, it is difficult Keeps the welds straight, essentially reducing the overall quality
