Manufacturing process for manufacturing tank body

Abstract

The invention provides a manufacturing process for manufacturing a tank body, which ensures that the manufacturing deformation of the tank body is low, the production stability of the tank body is good, and the continuous production operation is ensured. The production method comprises the following production steps that S1, a plate is wound into a circular ring shape in advance; s2, the bottom of the annular product is sealed and covered; s3, the semi-finished products subjected to cover sealing are fed into a stepping holding claw production line one by one, and cover bodies are arranged downwards; s4, pushing the semi-finished product into a pre-bending station, a coiling station, a rib carving station and a necking station in sequence through a stepping holding claw, and ejecting the semi-finished product upwards by a lower ejector rod seat at the corresponding positions of the pre-bending station, the coiling station, the rib carving station and the necking station, so that the semi-finished product is positioned with an upper tool of each station, and then the tool acts to complete the corresponding semi-finished product operation; and S5, in semi-finished product operation, the upper ring face is subjected to necking shaping through the final necking station, then falls to the surface of the workbench and is pushed away from the whole production line by the clamping jaw.

Description

technical field [0001] The invention relates to the technical field of manufacturing packaging cans, in particular to a manufacturing process for manufacturing cans. Background technique [0002] When the existing packaging cans are produced, the whole board needs to be wound into a ring shape, and then the processing technology of pre-bending, coiling, ribbing, and necking is performed on the upper circumference of the ring-shaped bottom, and then on the bottom of the ring shape. The bottom is capped. In this process, since the ring-shaped structure is in a linear stepping state, it needs to be positioned by an external positioning mechanism every time. The shape obtained by the previous process in the hollow state is easy to be positioned during the positioning process. Deformation occurs, which leads to the failure of the final cover plate to be installed normally, and the two ends of the tank body in the height direction are hollow, so it can only be transported in the f...

[0002] When the existing packaging cans are manufactured, the entire board needs to be wound into a ring shape, and then the processing technology of pre-bending, winding, ribbing, and necking is performed on the upper circumference of the ring-shaped bottom, and then the The bottom is capped. In this process, since the ring-shaped structure is in a linear stepping state, it needs to be positioned by an external positioning mechanism every time. The shape obtained by the previous process in the hollow state is easy to be positioned during the positioning process. Deformation occurs, which leads to the failure of the final cover to be installed normally, and it is used for the hollow state at both ends of the height direction of the tank body, which can only be transported in the form of a conveyor belt, and the conveying position of the conveyor belt has a large deviation. It is very easy to cause production accidents. Therefore, it is urgent to adjust the production process of the tank body
