For a long time, the processing technology of the closed hoop produced by our factory is in accordance with the traditional processing technology, that is, cutting strips with steel plates - rounding and rolling - stamping straight ends at both ends - spot welding tight ears - galvanizing. The plant leaders attach great importance to the high cost of materials, the large number of employees, the large number of equipment, and the long time-consuming. With the support of the plant leaders, the technology department organized relevant technicians to hold an analysis meeting to brainstorm on this problem, and developed a semi-automatic equipment integrating uncoiling and rounding rolling. It only needs one person to operate the notice, which has a great response in the domestic building insulation material industry, and the hoop rolling process can be completed, The work efficiency is increased by three times, which saves labor and time, and greatly reduces the production cost
the specific improvement method of making the closed hoop is:
1. Replace the steel strip with a certain specification of steel strip, which can reduce the material cost and save a superficial process of cutting the strip
2. Improve the closed hoop rolling mill. The original closed hoop rolling machine used a roller to roll, which was very laborious and unsafe to feed into the roller, and the rolling was not easy to adjust. The two sides of the closed hoop were easy to roll differently, and the ends of the closed hoop formed by rolling were always straight. The improved closed hoop rolling mill uses three passes of rolling, so it is easy to improve the utilization level and service level, and it is safe to adjust. The use method is: the steel strip coil of a certain specification is directly sent into the closed hoop rolling machine after uncoiling, and the required straight bolt tray shear strength testing equipment is adjusted. The diameter is rolled into a spring-shaped round roll forming closed hoop, so there is no straight head at both ends
3. Set a mold for cutting barrel hoop and connect it with the cutting machine. Place the barrel hoop rolled into a spring shape in the mold, one end of which is close to the positioning device, and then cut it into a closed hoop of the required specification with the cutting machine. In this way, the process of punching straight heads at both ends can be omitted
4. Then spot weld the stamped tight ears on both ends of the closure hoop
