Wheel section steel rim rolling machine

Abstract

The invention discloses a wheel section steel rim rolling machine. The wheel section steel rim rolling machine comprises a support, wherein the support is provided with a section steel rim rolling concave roller die which is connected with a power transmission device and is a fixed half concave die of a section steel rim; the support and the section steel rim rolling roller die are provided with clamping oil cylinders; the clamping oil cylinder is connected with a movable clamping half concave die of the section steel rim; the movable clamping half concave die is coaxial with the fixed half concave die; the support is also provided with a compression steel rim rolling convex roller die; and two ends of a roller shaft of the compression steel rim rolling convex roller die are connected with a movable support frame which is connected with a movable oil cylinder. The wheel section steel rim rolling machine has rational and compact arrangement and is suitable for rolling various wheel section steel rims, particularly for rolling concave and convex section steel rims, relatively thick section steel rims and large-diameter section steel rims.

Description

technical field [0001] The invention belongs to a processing device for vehicle parts, in particular to a production equipment for wheel shaped steel rims. Background technique [0002] There are two ways to produce the wheel rim, one is steel coil roll forming, and the other is made of wheel-shaped steel coil after rounding. Existing equipment for preparing wheel shaped steel coils all adopts a cantilever structure, that is, the shaped steel wheel rim round roll mold adopts a cantilever structure. This kind of equipment is used for the preparation of thinner section steel materials. It does not have high requirements for the demoulding of the rim during rolling, and it is easy to roll. For the rim with a concave-convex shape on the circumference, the above-mentioned equipment has the problem of demoulding; at the same time, for the rim with thicker steel material, when the equipment with the above-mentioned cantilever structure is rolled, the cantilever structure bears a l...

AI Technical Summary

Problems solved by technology

For the rim with a concave-convex shape on the circumference, the above-mentioned equipment has the problem of demoulding; at the same time, for the rim with thicker steel material, when the equipment with the above-mentioned cantilever structure is rolled, the cantilever structure bears a large moment, causing deformation and rolling. off-track problem

Therefore, the wheel-shaped steel coiling equipment with the above structure is not suitable for the coiling preparation of wheel rims with concave-convex shapes and thicker steel materials.
