Concrete production of steel barrel closures

For a long time, the closed hoop produced by our factory is processed in accordance with the traditional processing technology. That is to say, the shear strip of the steel plate - the round rolling shape - the straight ends of the stamping - the point welding - the ear - galvanization. Due to the high cost of materials, the high number of people, the large number of equipment, and the long time required, the factory leaders attach great importance to this. Under the support of the factory's leaders, the technical staff of the technical department organizes analysis sessions, brainstorms, and develops a solution to this problem. Set of semi-automatic equipment with open-rolling and spheronization, one-man operation can be used to complete the rolling and hoop rolling process. The work efficiency is increased by a factor of three, saving time and labor and greatly reducing the production cost.

The concrete improvement measures for making the closed hoop are:

1. The use of steel strips of certain specifications instead of steel strips can reduce material costs and eliminate the need for a process of cutting strips.

2, improve the closed hoop rolling machine. The original closed hoop rolling mill was rolled with a roller. The feeding into the roller was laborious and unsafe, and the rolling was not easy to adjust. The two sides of the closing hoop were easily rolled and the rolled hoop was closed. There is always a straight section at both ends. The improved closed hoop rolling mill uses three rolling shapes, which is easy to adjust and safe. The use method is as follows: after winding the steel strip of certain specifications into the closed hoop rolling machine after being uncoiled, there is no straight-end phenomenon at both ends of the round rolling and forming closed hoop rolled to a desired spring diameter.

3, set up a cutting bucket hoop of the tire and the cutting machine are connected together, the rolling barrel into a spring-like barrel hoop placed in the tire, one end tight * positioning device, and then cut to the required specifications with a cutting machine Closed hoop. This eliminates the need for stamping straight ends at both ends.

4. Then, stamp the formed tight ear spot on both ends of the closing band.
