Thin metal belt ring rolling mill

Abstract

The invention discloses a metal belt ring rolling mill which is characterized in that a support is arranged on the base, an upper supporting seat and a lower supporting seat are arranged in the support, a lower rolling roller is arranged in the lower supporting seat, and the upper supporting seat can slide along the support up and down under the action of a hydraulic mechanism. A left compression roller, a right compression roller and an upper floating compression roller are arranged in the upper supporting seat; a draw roller, a fixing roller and a middle rolling roller of the same heights are arranged between the lower supporting seat and the upper supporting seat; the draw roller and the fixing roller can be used for being sleeved in a thin metal belt ring to tension the thin metal belt ring; a stretching mechanism which drives the draw roller to move left and right is arranged in the base. According to the metal belt ring rolling mill, a rolling force is controllable in a rolling process, and therefore control of uniformity and precision of metal ring finished thicknesses can be effectively guaranteed. The circumference precision of a metal ring is guaranteed by the fact that a displacement sensor detects the length of the metal ring in an on-line mode. Meanwhile, the problem of 'off tracking' of the metal ring in the rolling process can be solved.

Description

technical field [0001] The invention relates to the improvement of metal thin strip ring rolling technology, in particular to a metal thin strip ring rolling mill used for a metal strip assembly of a continuously variable transmission device, and belongs to the technical field of metal thin strip ring rolling. Background technique [0002] Continuously variable transmission is one of the advanced transmission methods of automobiles. Among them, the metal belt type continuously variable transmission is the main one, and the metal belt, one of its main core components, is composed of two sets of multi-layer thin belt rings and hundreds of thrust plates. For the above-mentioned thin strip ring, firstly, a section of steel strip made of high-strength alloy steel is welded into a ring at both ends, and then it is cut into narrow metal rings of equal width, and finally the metal ring is made into a certain length by rolling method. thin belt loop. [0003] At present, only t...

AI Technical Summary

Problems solved by technology

From the partially disclosed thin strip ring manufacturing technology, there are mainly problems in the following aspects: 1. The rolled metal thin strip ring has low precision and poor stability

2. Low rolling efficiency and many human factors

3. Due to the inertia of the rolling roll, it cannot be stopped immediately after the end command is issued, and the metal thin strip ring will be subjected to additional rolling

4. The position deviation of the metal belt ring on the roll during the rolling process
