Research And Development Of Silk Fabric Fast Bar Technology

at present silk It is very difficult to make straight strip and radioactive strip with 1/16 inch width or more. It can only be done by hand by hand. It is faced with low efficiency, high cost and long service life. To solve the above problems, we need to break the routine and break through and innovate the technological methods. Therefore, the QC group of the company's special process development has chosen the key research task and the research and development of silk fabric fast bar technology.

Set the goal: at present, the production capacity of special bar can not meet the customers' requirements for futures and exist simultaneously. Low efficiency The company is demanding to solve this bottleneck. If the requirements for order fulfillment are met, the radioactive bar must reach 1.5 m / min, and the 1/16 inch bar must reach 2 m / min. The team will serve as the goal of this QC activity.

Put forward the plan: after the discussion of the group members, it is considered that the brand new Fast car bar The method must be operated simply, and the efficiency can be further improved by ensuring the quality and reducing the repair rate by using the tools.

Through the experimental analysis of the selection of industrial appliances, the team determined the development of 3 fast track bars, the technical research and development of double stitched sewing joints, and the technical development of the computer's herringbone car bar technology. After trial verification and group members' comprehensive consideration, the two needles were selected on the computerized herringbone car, and the test was carried out with the presser foot and the needle plate. Through the analysis and experimental comparison of the technical research and development options of the computerized herringbone car, the team finally confirmed the best plan and formulated the countermeasures table.

Implementation of countermeasures: group members design drawings of accessories according to the parameters determined in the plan and use drawing software. According to the design drawings, the developers have developed double needle, foot pressing slotting and needle plate welding arching device. The team members install and debug the components and equip them with standard equipment. The group carried out on-the-spot explanation, demonstration, guidance and examination for the fast car bar plan, so that the relevant operators mastered the sewing method.

After the implementation of the plan, the group made statistics on the production of ~10 June 2013 large truck orders. The average efficiency of 1/16 inch bars reached 2.5 m / min, and the average efficiency of the radioactive bar reached 2 m / min.

Benefit: using the fast strip technology, the cost of producing 1/16 inch car bars dropped significantly from 0.8 yuan / meter to 0.2 yuan / meter, and the radioactive bar dropped from 1.8 yuan / meter to 0.2 yuan / meter, which brought significant economic benefits for the company.
