A rolling machine for circular steel rings of cement poles

Abstract

The invention provides an annular steel plate ring roller press of a concrete pole. The annular steel plate ring roller press is composed of a support component, a movable wheel component, a front pressing wheel component and a rear pressing wheel component, and is characterized in that the movable wheel component, the front pressing wheel component and the rear pressing wheel component are sequentially arranged on the support component, one end of the support component is provided with an open movable support; the movable wheel component is driven by a hydraulic cylinder, so as to realize upward and downward movement; the front and rear pressing wheel components are respectively connected with an outside motor so as to realize initiative selection movement. According to the annular steel plate ring roller press provided by the invention, by adopting a way of rolling to form a circle, an annular steel plate ring needed by the concrete pole can be rolled and processed quickly and efficiently, therefore the annular steel plate ring roller press has the characteristics of being simple in structure, convenient to operate and the like; furthermore, the annular steel plate ring roller press is provided with a four-link mechanism with the functions of locking and anti-rotating, therefore materials can be simple and safe to take.

Description

technical field [0001] The invention relates to the field of cement pole manufacturing equipment, in particular to forming equipment for processing circular steel rings of cement poles. Background technique [0002] Assembled cement poles (more than 8 meters in length) are generally assembled by butt joints of two or more flange-type or steel-plate ring-type cement poles. The production efficiency and cost of flange plates or steel rings directly affect production efficiency and cost. Wherein, the flange plate or the steel plate ring all contain circular steel plate rings, and its production methods mainly include steel plate rolling method and cast steel casting method. In the existing rounding machine, the roller shaft is mainly cantilever type, and the rolled product has a spiral structure, and the roundness of the rolled product is poor, so it cannot be directly welded and formed. There are also large-scale rolling machines, the roller shaft of which mainly adopts a si...

AI Technical Summary

Problems solved by technology

In the existing spheronizing machine, the roller shaft is mainly cantilever type, and the rolled product has a spiral structure, and the circularity of the rolled product is poor, so it cannot be directly welded and formed

There are also large-scale rolling machines, the roller shaft of which mainly adopts a simply supported beam structure, and mainly processes steel plate rings with large diameters (more than 0.5m in diameter), and generally leaves a large gap for taking out the roller from the roller shaft. Pressed semi-finished products still need follow-up processing before they can be welded into circular rings, and the cost of processing equipment is relatively high. It is suitable for large-scale cement pole factories. For small cement pole factories, equipment investment is relatively large

However, the quality and strength of the circular steel plate ring produced by the cast steel casting method are not as good as those produced by the steel plate rolling method.
