Description

Horizontal three-roller steel belt gear rolling machine

Technical Field

The utility model relates to a steel rolling machinery technical field, concretely relates to horizontal three-roller steel band rolls tooth machine.

Background

In the whole process of welding the inner gear tube, the steel strip rolling belongs to the core technology and is also difficult. What traditional steel band rolled tooth was used is the two rolls of imitating two roll mill designs rolls tooth machine, its shortcoming lies in: 1. when a steel strip is hard or the width of the steel strip is wide, the rolling force of a rolling tooth needs to be increased, the roller is bent due to the force, the diameter of a roller shaft needs to be increased in order to resist the bending, the influence caused by the diameter increase is not large for a roller with a smooth surface, but for an embossing roller, the increase of the shaft diameter means that an embossing die needs to be increased, the manufacturing cost of the embossing die and the diameter of the embossing die are increased in a square multiplying factor, the embossing die belongs to a worn product, and the cost of a single embossing die is too high, so that the control of the production cost is not facilitated. 2. The method is suitable for rolling straight-tooth steel belts, but the steel belts are elongated due to the tension of a tightening wheel during the rolling of helical teeth, the tooth form number on the steel belts has a slight difference with the tooth form number of the die, so that the steel belts cannot be completely meshed, and the multi-rolling method is not suitable for rolling the helical-tooth steel belts. Thus, there is room for improvement.
