Pipe Welding Machine Guidance mechanism

This paper points out some problems often encountered in the production of welded pipe machine, and briefly analyze the crux of the problem, hope that we have the right medicine, targeted attention to the pipe machine in these aspects of adjustment and maintenance, for the maintenance of the continuous stability of the pipe Production has some help.

Common faults of welded pipe machines

The failure of the welded pipe machine is relatively more, and the cause of the failure is also more complex, often a result caused by a variety of reasons, or a cause can cause several results. Here we have a more common description of the failure of the pipe machine.

1 scratch

In the process of production of pipe fittings in the process of tube blanking mainly caused by two parts, one guide mechanism, the second is the extrusion welding institutions.

1. 1 scratches of guide mechanism

The scratches of the guide parts generally occur on both sides of the tube, and the improper adjustment of the guide structure with the guide sleeve may cause frictional scratches on the upper and lower surfaces of the tube. The main reason is that the height of the guide sleeve is not correct, or the upper and lower guide roller bearing damage, can not be a good control of the tube, so that after the formation of friction with the guide sleeve.

1. 2 Extrusion welding mechanism scratches

The scratches caused by the squeeze rollers mainly occur at the bottom of the tube. The reason is that the holes do not coincide with each other. The lower edge of the extruder roll does not match the height of the rolling line. The

2 weld quality failure

2. 1 through the long welding

Welding refers to the misalignment of the two edges of the tube when it is stacked together. In the length, the length of the welding with the length of the length of welding through a few meters in general, or even longer. In the dislocation of a slight deviation of a few millimeters, there is a total dislocation equal to the wall thickness. The reason for the long welding is mainly due to the following factors: ① axial lubrication of the squeeze roller ② bearing damage ③ squeeze roll bending ④ large pressing force ⑤ guide roll tilt ⑥ guide roll diameter is different
