Core roll rotating device of vertical ring rolling machine

Abstract

The core roller rotating device of the vertical ring rolling machine is an independent attachment mechanism of the ring rolling machine. It uses the oil motor or electric motor installed outside the lower support to pass through the mechanical transmission pair (such as gears, sprockets or pulleys) after deceleration. , drives the support shaft installed in the lower support, together with the core roller tightly inserted in the support shaft to rotate together, so that the core roller has the function of active rotation, which is different from all current vertical and horizontal ring rolling machines The characteristics make it possible to enlarge the vertical ring rolling machine with simple structure and low cost, and bring convenience to the operation in the initial stage of ring rolling, which is conducive to improving production efficiency and reducing waste loss.

Description

Technical field: [0001] The core roller rotating device of the vertical ring rolling machine of the present invention is an additional device designed for the enlargement of the ordinary vertical ring rolling machine, and belongs to the field of mechanical design and manufacture. Background technique: [0002] Ring rolling machines have been around for decades, and are widely used in the mass production of various rings with an annual output of tens of millions of tons, such as inner and outer rings of various bearings, flanges, ring gears, and train tires. Ring rolling machines are mainly There are two types of vertical ring rolling machines and horizontal ring rolling machines. The former is used for small and medium-sized rings, while the latter is used for large rings. The structure of the horizontal ring rolling machine is complex and the cost is high. The price is often more than ten times, or even dozens of times, that of ordinary vertical ring rolling machines. In t...

Problems solved by technology

It should be pointed out that the ring blank of the vertical ring rolling machine is vertically set on the core roller (while the ring blank of the horizontal ring rolling machine is lying flat on the worktable), the weight of the ring blank is entirely borne by the core roller, and the main rolling wheel The tangential friction formed when cutting into the surface of the ring blank must be greater than the moment of inertia and other rotational resistance of the ring blank, the core roller and the lower support, otherwise the main rolling wheel will not only be unable to rotate the ring blank, but will be pressed into the outer surface of the ring blank The pits are formed, so that the ring rolling process cannot be carried out, especially for large ring blanks with large eccentricity of the inner and outer circles, the belt rotation is more laborious and the contradiction is more prominent. one of the important reasons
