Guiding device of large diameter cast iron pipe external spraying machine

Abstract

The invention discloses a guiding device of a large diameter cast iron pipe external spraying machine. A supporting wheel (5) is arranged on a base (1); a middle supporting seat (3) is laid on the supporting wheel (5) through the bottom surface of the middle supporting seat (3); guiding wheel devices (6) are arranged on the base (1); the guiding wheel devices (6) are arranged on two sides of the middle supporting seat (3); and the guiding wheels of the guiding wheel devices (6) contact guiding surfaces fixed on the middle supporting seat (3) through rims. By adopting the technical scheme, thereliable centring performance of cast iron pipe products is ensured, the products are prevented from producing additional torsional forces, the damage to the guiding components of the guiding device of the cast iron pipe external spraying machine is small, the down time for abnormal overhaul and changing is reduced, and the labor intensity of workers is reduced, the spraying processing quality ofthe outer surface of the revolving body of the cast iron pipe is improved, and the purposes of production increasing and productivity improving, and energy saving and cost reducing are realized.

Description

technical field [0001] The invention belongs to the technical field of production equipment in the metallurgical industry, and relates to process equipment for a centrifugal ball mill cast iron pipe production line. More specifically, the invention relates to a guide device for a large-diameter cast iron pipe external spraying machine. Background technique [0002] At present, in the production process of the centrifugal ball milled cast iron pipe, the outer surface of the cast iron pipe is sprayed by an external spray machine. The external spraying machine is divided into three parts: the socket support part, the socket support part and the spraying part. [0003] In order to meet the process requirements, the bearing and socket supporting part of the external spraying machine should keep a certain distance from the running line of the workpiece in the production line when there is no workpiece at this station. After the workpiece to be sprayed enters the station, the beari...

AI Technical Summary

Problems solved by technology

The early guide device was to set four sets of guide strips on each support frame. Because the production rhythm was fast and the support part reciprocated frequently, even if the guide strips were made of high-quality wear-resistant steel, their service life could not be extended. Various factors introduced The eccentricity problem caused the four sets of guide strips to wear differently

When replacing, the four groups must be replaced together at the same time, which not only increases the production cost, but also increases the time for equipment adjustment and maintenance, which has a great impact on normal production
