Multi-station continuous machining production line after steel pipe hot-dip galvanizing

Abstract

The invention belongs to the technical field of steel pipe galvanized machining, and specifically relates to a multi-station continuous machining production line after steel pipe hot-dip galvanizing.According to the main technical scheme, the multi-station continuous machining production line is mainly composed of an upward track connected with a zinc pot, a progressive conveying device connectedwith the upward track, a downward track arranged on the tail end of the upward track, and a water-chilling device connected with the downward track; the upward track is provided with a steel pipe outer surface blowing-and-wiping station, and a water-cooling continuous conveying station is arranged in the water-chilling device; the progressive conveying device comprises a rack, a material receiving station located at lateral support arms of the rack, a steel pipe inner surface blowing-and-wiping station, and an air cooling station; and progressive lifting support plates arranged close to two lateral support arms with synchronous movement, and the upper portions of the progressive lifting support plates are provided with multiple grooves for longitudinally lifting galvanized steel pipes forhorizontally conveying the galvanized steel pipes between adjacent stations in a progressive mode. The multi-station continuous machining production line has the advantages of reasonable structural design, compact and coherent machining links, being capable of processing hot-dip the galvanizing steel pipe in a dual-thread mode.

Description

technical field [0001] The invention belongs to the technical field of galvanizing processing of steel pipes, and in particular relates to a multi-station continuous processing production line for steel pipes after hot-dip galvanizing. Background technique [0002] The process of producing galvanized steel pipe includes steel pipe degreasing→water rinsing→pickling rust removal→water rinsing→plating flux treatment→drying→hot dip galvanizing→outside blowing→inside blowing and wiping residual zinc→cooling→passivation treatment→drying →Inspection, packing. This series of processing needs to continuously transfer the steel pipe among the above-mentioned multiple stations, especially after the pre-treated steel pipe is hot-dip galvanized for external blowing, internal blowing, and cooling processes, the processing process needs to be closely coherent, and the processing time is required Harsh. [0003] At present, the processing after hot-dip galvanizing of steel pipes is mostly...

AI Technical Summary

Problems solved by technology

[0003] At present, the processing after hot-dip galvanizing of steel pipes is mostly linear processing, which delays the production progress; the integration of each process link is not high, and the processing time of a single station is long, and the hot-dip galvanized steel pipes cannot be processed within the design cycle, which is prone to produce defective products; In addition, each station needs manual monitoring, and the position of the steel pipe is corrected at any time, which consumes a lot of labor resources and increases the production cost of the enterprise.
