Cement pipe machine is the production of cement pipe machine is a kind of simple and practical, the most widely used equipment, with easy operation, convenient maintenance, wearing parts less features, mainly for drainage, sewerage, highway culvert, and motor pumped well pipe production, is popular with users. The roller shaft of the cement pipe making machine is a pressing roller mechanism which drives the rolling circle of the cement pipe die, which is under the action of tension, compression, shear, torsion and bending. The acting force is mainly on the working face of the rolling ring and the roller shaft, and the working surface is easy to wear. Wear of roll shaft can not only reduce the roll shaft strength, but also affects the product quality, on axis roll wear, at present some factory by arc welding and machining; some factory is used vibration surfacing welding. These repair methods are not ideal. Today, small make up to share with you about the more reliable cement pipe mill roll shaft repair method.

Cement pipe machine specifications of many models, is generally used to produce diameter 300 ~ 2500mm, long 1000 ~ 5000mm of the drainage pipe, the diameter of the roller shaft diameter and the ratio of the diameter of the tube is 1:3 ~ 1:5. Short diameter of the roller, maintenance is relatively easy, the choice of repair welding and then turning method is possible, however, for large diameter, length of the roller shaft, maintenance is very difficult. First of all, to use the correct welding technology to prevent welding deformation, and to select a good welding rod material, followed by the repair welding turning, but also a special machinery and equipment for the transformation of equipment. Because of the nature of the plant is different, there is no maintenance equipment, but also commissioned processing.

Cement pipe machine is the production of non-standard equipment according to market demand, the roller material is difficult to purchase, most of the alternative materials purchased from other manufacturers, such as carbon steel 45 seamless thick wall steel pipe. Since the material is not easy to purchase, maintenance and so difficult, the roller shaft can repair the problem, the design must be considered in order to extend the service life of the roller shaft.
