Roller type single rotating hub straightening unit

Abstract

The invention provides a roller type single rotating hub straightening unit. The roller type single rotating hub straightening unit comprises an operation table which is provided with a front pinching device, a straightening device, a rear pinching device, a shearing device and an unloading device, wherein the front pinching device comprises two pair of main pinching groups, and guiding end openings arranged at one ends of the main pinching groups, and manual rollers which are arranged up and down are arranged between the main pinching groups; the straightening device comprises a shell, a material inlet and a material outlet, a plurality of roller groups are arranged inside the shell and comprise two rollers which are arranged up and down, and are arranged in an intersecting manner, the two ends of each roller are provided with adjusting structures. According to the device, as the rollers which are arranged in an intersecting manner, the surfaces of the rollers are in bent state, a steel wire penetrates through the parts between the rollers, a forward tensile force can be applied to the steel wire when a rotating hub rotates due to an included angle being 45 degrees; compared with a conventional method of modular multiple bending, the straightening unit has the advantages that the steel wire does not need to be coated by coatings, so that the work procedures are reduced, and the environment pollution is alleviated; meanwhile, the friction on the surface of the steel wire is slight, and the straightening is accurate.

Description

technical field [0001] The invention relates to the technical field of steel straightening, in particular to a roller-type single-rotary hub straightening unit. Background technique [0002] At present, in my country's processing and manufacturing industry, there are many special steel rods and wires that need to be straightened. Taking air valve steel as an example, with the vigorous development of the automobile manufacturing industry, there is a great market demand for the quality, specification and quantity of air valve steel. Due to the special process requirements for the production of air valve steel, the steel wire after heat treatment It has the characteristics of high strength, high hardness, and high brittleness, especially the high requirements for straightening accuracy. The process requires straightening to directly enter the grinding sequence, so straightening is very difficult. In the current production of valve steel The straightening equipment used is almo...

Problems solved by technology

However, when the pinch force is small, it cannot meet the straightening needs

Increasing the clamping force will cause the material to be flattened

[0004] 2. Since most of the modules are made of cast iron, the friction between the bar and the module makes the module quickly worn out and scrapped, resulting in a large amount of consumption of the module, which leads to inaccurate straightening

The use of toner is affected by the weather. In the case of humid weather in the south, the toner will become sticky and cannot be used directly. The toner must be dried, which will increase the production cost, and the toner is easy to use. Flying, resulting in poor working environment and affecting personnel health
