Steel ring and production process thereof

Abstract

The invention relates to a steel ring which is used for the loading wheel and the inducer of a snowmobile and provides a steel ring and a production process thereof. The steel ring provided by the invention comprises a rim, wherein the rim is punched and formed integrally, the center of the rim is provided with a reference plane, the center of the reference plane is provided with a positioning hole, the outer ring of the rim is stretched into a side wall, the other end of the side wall is provided with an inward rolling structure, and a structure with the shape of a curved face is arranged between the reference plane and the side wall. The thickness of the plate material of the rim reaches 9.5mm. The forming process of the production process of the steel ring provided by the invention comprises the steps of stretching and rolling and comprises the concrete following steps: firstly, pressing a blank by a material pressing panel, then stretching a pressing material of a terrace die and enabling the pressing material of the terrace die to enter a die shank of a concave die for stretching; and rolling after the stretched and formed workpiece passes through the front port of a vehicle. The steel ring provided by the invention increases the diameter and the thickness of the steel ring, also widens and improves a caterpillar device and enhances the bearing capacity and the stability.

Description

technical field [0001] The invention relates to a steel ring, in particular to a steel ring used for road wheels and induction wheels of snowmobiles and a production process thereof. Background technique [0002] Snowmobile, its main purpose is a tracked logistics support vehicle that performs tasks in snowy, mountainous, swampy, flooded, muddy or desert areas, so it is sometimes called "all-terrain military transport vehicle". All the surrounding countries near the Arctic, such as Northern Europe, North America, Russia and other countries, are affected by the natural climate and are covered with ice and snow all year round. Snowmobiles have already become one of their main means of transportation, especially in the transportation of military logistics materials. The demand is particularly large. In terms of scientific investigations, snowmobiles also provide material support for scientific expedition personnel who go deep into the Antarctic and the North Pole. [0003] Thr...

AI Technical Summary

Problems solved by technology

In some western countries, such as the U.S. LMC1450 crawler snowmobile, the width of the track shoes is 644mm, and the steel ring is increased to 1M. Although the various indicators of the conventional snowmobile have been improved, its bearing capacity is less than 1.5T. Can not meet the needs of the market
