Research on Occupational Disease Hazards in the Process of Automobile Spring Production

Automobile springs are one of the important parts of automobiles. With the development of the automobile industry, the production of automobiles is rising, and the demand for automobile springs will further increase. The spring manufacturer will then hire more workers to cope with the increased production lines or new projects. In order to reduce or eliminate the occupational hazards in the production process of automobile springs and protect the health of workers, the author passes the types and distribution of occupational hazards of a certain automobile spring company, the results of the detection of occupational hazards, the health monitoring data of workers, The analysis of occupational disease hazard prevention measures, etc., to determine the key control points of occupational disease hazards, and to develop protective countermeasures, to provide a scientific basis for the prevention and treatment of occupational disease hazards in automobile spring manufacturing enterprises.

The research object is a spring production line and working workers of a certain automobile spring company. The research method uses occupational health survey, occupational health test and other methods to collect data and data, identify the occupational hazard factors existing in the spring production process, analyze the occupational disease hazard based on the test results, occupational health check results, and determine occupational hazards based on occupational health survey data. Critical control points and develop appropriate countermeasures.

Research results, production process The spring production plant mainly produces suspension springs and valves (damping springs). Although the production process of the two products is different, the production process is roughly similar. Generally, the following operations can be summarized: System, tempering, chamfering (grinding), flaw detection, shot peening, setting, strong pressure, testing, surface treatment, load sorting, marking (color standard), etc.

Stainless Steel Sliding Door

Characteristics and Advantages

(1) Intelligent control design: adjustable main parameter and secondary parameter automatically according to the weight of door leaves;

(2) Low noise: Special static sound track, integration of motor, worm-gear and retarder.

(3) Anti-clamping function: automatically reverse when meeting barriers;

(4) Unique electronic motor lock: the motor will lock up when the door is forced to open.(controlled by remote or switch)

(5) Tighten force: seal door when closed, power consumption approximately 10W under standby;

(6) Advanced brushless motor(36V,100W) can automatically adopt different heavy door leaves;

(7) Bi-doors inter-locking: one of the door leaves always remains closing;

(8)Safety sensor terminal: sensor stops working when door closed;

(9)Unique coating technology: never rusty;

(10)Easy and convenient to install;

(11)Working Process: when the door leaf closes to the right place, the door leaf will slightly shift to the door frame and the ground. The rubbers on the four sides of the door leaf will completely combine with door frame and ground, which ensures air tightness. When the door is open, the rubbers will separate from door frame and ground, which avoids contraction on the ground.

Technical Specification

Technical Details:

(1) Rubber lining sealing technology combined with V groove on the guide rail enables the door completely sealed when the door closed;

(2)Special door body location technology. Semicircular surface beam on the ground matches with the V style groove at the bottom of door leaf, which stop the door from swing and make sure it moves stable and smooth;

(3) The door body decorated with matte stainless steel or spray surface, and on the middle and both sides with sealing stripes to ensure the hermetic effect.

(4)Feet sensor switch applied to avoid contagion;
