Embodiment Construction

[0055] Such as figure 1 with figure 2 As shown,

[0056] The present invention aims to provide a freely foldable, centrifugal steel mold hub repair process. This method is to make a positioning mold 2 with a spindle 3 ( figure 1 ), the mold fixing disc is the same as the base flange of the fixed hub on the centrifugal steel mold. Simulating the base flange, fixing the hub on it is equivalent to moving the running wheel to the lathe for processing. The hub is usually formed by a combination of two semi-circular rings. First, we analyze the reason for the stress on the outer surface of the hub. During the long-term contact between the hub and the power wheel, the outer surface of the hub will generate tension or compressive stress. The role of the fastening bolts, the wheel hub fits on the centrifugal steel mold is not reflected in appearance, but in fact the wheel hub and the base flange of the centrifugal steel mold are tightly bonded together. When the centrifugal steel mold i...

Abstract

Provided is a centrifugal steel mould hub repairing process. In the process of long term contacting of a hub and a power wheel, the outer surface of the hub can generate tension force, namely, pressure stress, once the hub is taken down from a centrifugal steel mould, under the function of the tension force on the outer surface of the hub, the inner diameter of the hub is bound to reduce and deform, and is difficult to repair. The centrifugal steel mould hub repairing process comprises the following steps: manufacturing a positioning mould with a core shaft, a mould fixing plate and a basic flange plate on the centrifugal steel mould for fixing the hub are identical, the basic flange is imitated, the hub is fixed on the mould fixing plate, equivalently, a running wheel is moved to a lathe for processing, improvements relies in steps of increasing stress relief, diameter and shaft bi-directional pressing and fixing in the process of dismantling and positioning. Due to the fact that same order and same position in an integrated task is not restricted by sequencing and processing, single mode repair cycle is just 4.5 hours, general repairing of a 10 meters mode can be completed in 2 to 3 days, time saving effect is very obvious, and emergency repairing is benefited.

Description

Technical field [0001] The invention relates to a repairing method for a round workpiece, in particular to a repairing process of a centrifugal steel mold hub, which is a repairing process for a centrifugal steel mold. Background technique [0002] Centrifugal steel molds generally refer to steel molds for making pipe piles, electric poles, and drainage pipes. After a long period of use, due to the collision, bending and unreasonable repair techniques of the centrifugal steel molds in the lifting and transportation of the stations, the steel molds are Uneven wear during operation, and serious defects such as the out-of-roundness of the centrifugal steel mold running wheel and different shafts, must be repaired reasonably, otherwise it is not suitable to continue to use. [0003] There are several current repair processes: [0004] 1. Remove the hub from the running wheel, combine it with electric welding, align it, turn it, and then disassemble, install and reset, and it is complete...
