Cement pipe mold cylinder deformation Repair
Some cement pipe mold concentricity better, running wheel and mounting flange with the gap are within a predetermined tolerance band. But in fast running always beating. In this case, no analysis of other reasons, it may be cement pipe mold emphasis. Reason than the following categories: poor cement pipe mold structure itself - no blank flange bearing finishing, uneven thickness; mold seam iron tongue and groove width varying partial, uneven thickness; uncivilized operation and other damage.
Yojimbo emphasis to check the direction of the mold: the mind fixed cylinder rod (mandrel requirements and concentric), rotating cylinder, to be automatically stopped to make a mark. So again, if in a labeled, in the corresponding radial, i.e. reverse biased plus welding with weights. Trial and error, until the post-rotation is applied to the mold can be stopped at any position.
Mold cylinder tube deformation cement specific reasons as follows:
① maintenance is not timely; ② dynamic change in the alternating load; ③ welding in the manufacturing and maintenance process produces (cutting) the collusion of power; improper operation of the mold workers ④ premature fatigue, creep up, so three-dimensional rendering distortions.
The exhibit irregular or regular shape, weight bias will make the mold side, the center of gravity of the cylinder offset, jitter is inevitable.
Its repair method is more complicated, here initiate, simply make an introduction.
The first: force method.
① principle: force balance method. As shown in Figure 1. Make sufficient rigidity or strength of the top pressure (supporting) planes, with a jack to force adding water.
