Steel drum production process and corresponding four-station machining device thereof

Abstract

The invention discloses a steel drum production process through which arrangement of a conveying belt is reduced, the whole production line is shortened in travel, production efficiency is improved, occupied area is reduced and land cost is saved. The production process includes the following steps: 1, feeding a product into a welder prior to edge rolling and seam welding; 2, supplementarily coating the inside and outside of a drum body through a supplementary coater; 3, drying via an electromagnetic drying line; 4, performing air drying and cooling via a storage tank conveying belt; 5, entering a four-station machining device, and sequentially passing through a flanging and prerolling station, a cone expansion station, a coiling station and a rib expansion station; 6, conveying the drum subjected to rib expansion to a turnover-free bottom seal combination machine through the conveying belt and sealing the bottom; 7, feeding the drum with the bottom sealed into an automatic spot welder through the conveying belt, and mounting lugs to drum lugs.

Description

technical field [0001] The invention relates to the technical field of convenient barrel manufacturing equipment, in particular to a steel barrel production process, and also provides a four-station processing device corresponding to the steel barrel production process. Background technique [0002] The existing production process of the convenience bucket is based on the welding seam machine, the repair coating machine, the electromagnetic drying, the pre-rolling station, the flanging station, the bottom back sealing station, the expansion station, the winding station, and the reinforcing station. , Spot welding machine, in the pre-rolling station, flanging station, bottom cover station, expansion station, winding station, reinforcement station according to the least arrangement of conveyor belts, see the application date is 2014 On July 17, the patent number 201420396802.4 of "a double-line two-station processing device" and the patent number of 201420395939.8 "a double-li...

AI Technical Summary

Problems solved by technology

[0002] The existing production process of the convenient bucket is according to the welding seam machine, re-coating machine, electromagnetic drying, pre-rolling station, flanging station, bottom sealing station, expansion station, coiling station, and rib-expanding station. , spot welding machine, arranged according to the minimum number of conveyor belts between the pre-rolling station, flanging station, bottom sealing station, expansion station, coiling station, and rib-expanding station, see the application date is 2014 On July 17, the patent No. 201420396802.4 for "a two-line two-station processing device" and the patent No. 201420395939.8 "a two-wire three-station processing device" also required the flanging station and the bottom sealing station Conveyor belts are arranged between them, and conveyor belts are arranged between the bottom sealing station and the expansion station, that is, at least two conveyor belts, which make the wiring of the complete production line of the entire convenience bucket long, making the stroke of a single convenience bucket long, resulting in production Low efficiency, and due to the long wiring of the production line, it occupies a large area, resulting in high land costs
