Bearing steel ball-cog intermediate-frequency heating continuous rolling device

Abstract

The invention provides an intermediate-frequency heating continuous-rolling device for a steel ball of a bearing which is characterized by including a conveying section (1), a heating section (2) and a ball-rolling machine (3). The heating section (2) further includes a conveying wheel (4) and an induction heating loop (5); the conveying section (1) is connected with the heating section (2); the heating section (2) is connected with the ball-rolling machine (3). The intermediate-frequency heating continuous-rolling device for a steel ball of a bearing provided by the invention connects the conveying section, the heating section and the ball-rolling machine into a whole for becoming a production line; people are only responsible for pulling a long material on the conveying section from a material frame; besides, the conveying wheel is arranged to lead the long material to be heated during the conveying process; after being heated directly, the long material enters the ball-rolling machine for rolling without manual feeding and discharging, saving the manpower and improving the production efficiency as well as extensively saving the materials.

Description

technical field [0001] The invention relates to a bearing steel ball processing equipment, in particular to a bearing steel ball billet medium-frequency heating continuous rolling device. Background technique [0002] The traditional manufacturing processes of bearing steel ball blanks mainly include cold heading, hot heading and stamping, which are respectively realized on cold heading machines, presses (punch machines) and air hammers. Among them, cold heading is mainly used in the manufacture of bearing steel balls with a diameter of less than 25.4mm, and hot heading and hot stamping are mainly used in the manufacture of medium and large bearing steel balls with a diameter of 25.4mm or more. [0003] The hot rolling process is a new type of forming process for medium and large bearing steel ball billets. In my country, the Beijing University of Science and Technology has tested this process since the 1950s. With the technical difficulties overcome, this process has achiev...

AI Technical Summary

Problems solved by technology

[0005] In the prior art, the intermediate frequency heating equipment and the rolling equipment are independent, the production process cannot be carried out continuously, and manual discharging and feeding are required, the production efficiency is low, and because in the process of rolling bearing steel balls, a There is always waste at both ends of the material, and a long material will inevitably increase a lot of waste when it is broken into a short material
