Cold spinning device applied to steel seamless gas cylinder

Abstract

The invention discloses a cold spinning device applied to a steel seamless gas cylinder and specifically relates to the field of cold spinning processing devices of gas cylinders. The cold spinning device comprises a rack, wherein a cylinder preform clamping rotation mechanism is fixed on one side of the bottom of the rack; a rotary wheel mechanism is disposed above the cylinder preform clamping rotation mechanism; the top of the rotary wheel mechanism is driven by a screw rod; and two ends of the screw rod are fixedly connected to the rack by bearings. The device disclosed by the invention has the beneficial effects that an abnormal-shape spindle is supported by a fastening bearing sleeve assembly; when the abnormal-shape spindle is rotated, the spindle gets contact with multiple balls distributed on a shuttle-shaped face, so horizontal wear is reduced; in addition, the abnormal-shape spindle can be rotated more stably, and eccentric shaking does not take place; and when wear takes place between the abnormal-shape spindle and the balls, the whole fastening bearing sleeve assembly can be extruded by rotation of a fastening ring through configuration of multiple reserved fastening holes, so the balls can be fitted with the abnormal-shape spindle and thus stable rotation of the abnormal-shape spindle can be realized.

Description

technical field [0001] The invention relates to the technical field of cold spinning processing devices for gas cylinders, and more specifically, the invention relates to a cold spinning device for seamless steel gas cylinders. Background technique [0002] In the current production of gas cylinders, the manufacturing process of drawing and cooling has gradually matured. The preforms produced by this process have basically no defects on the outer surface and uniform wall thickness, so they are deeply loved by customers. This method The preforms produced have been procured in large quantities by large gas cylinder companies around the world. [0003] The preform produced by the cold spinning method, after the surface of the preform is cold-spun, the surface quality is greatly improved, the outer surface is basically free of defects, and the integrity and consistency of the preform are also very good. However, during the cold spinning process, due to the wear of the cold spin...

Problems solved by technology

[0005] However, the above-mentioned technical solutions still have some disadvantages in actual application. For example, although the technical means of spinning shaft segments and different diameters are adopted, the anti-shake effect is good in a short time, but after long-term use, each shaft segment will still exist. The problem of mutual wear of the bearings socketed with it requires replacement of the entire spinning shaft and spinning wheel, which is not economical and practical
