The function of the steering arm is to transmit the force and motion of the steering gear to the straight rod or the tie rod, thereby pushing the steering wheel to deflect. The processing vehicle steering rocker arm is a very important part in the steering system of the automobile, and is a security component of the automobile product. Key parts. Therefore, it is especially important to ensure the processing quality of the steering arm. Because of the wide variety of processes in the processing process, there are many types of equipment required, so processing and production are difficult, and it is necessary to arrange processing equipment and formulate various processes. Succession.
The connection between the steering arm forgings in the process is very important, the process flow is as follows: incoming (forging) → flaw detection (fluorescent flaw detector) → drilling small end positioning hole (vertical drilling) → milling two planes (milling machine) → Milling two facets (milling machines) → processing large end spline holes (drilling machines or lathes) → processing large end splines (pull beds) → trimming large end splines (presses) → trimming spline end faces (lathes) → processing Small end taper hole (lathe) → processing rocker arm installation reference line (punch) → flaw detection (fluorescent flaw detector) → electrophoresis or painting (electrophoresis equipment or baking equipment) → lettering, packaging, storage (lettering machine, baler) .
The steering arm is applied to various fields in daily life, and its function is large and small. With the high requirements of some equipment, the steering arm is constantly improving its own quality. The above is the steering arm processing flow.
For the steering arm forgings, the structure should ensure the convenience of feeding, setting, discharging, and cleaning the waste. For the processing of small parts, the operator’s fingers, wrists or other parts of the body should not be allowed to extend into the mold area; For the processing of arm forgings, if the operator has to work in the mold, it is necessary to reduce the range of the mold as much as possible, to shorten the time for a certain part of the body to stay in the mold, and to specify the scope of the dangerous area of the mold, and to provide necessary protection. Measures and devices.
It is not allowed to cause scrap or workpiece missiles during the processing of the steering arm forgings, which may affect the operator’s attention and even damage the operator. In addition, the punching of the punching parts shall be avoided. The operator is not allowed to perform the punching operation. Excessive range of motion, avoiding the posture that makes the body lose stability; it is not allowed to have too much and too difficult movements during operation. It should be avoided as much as possible when there is strong noise and vibration during stamping. The mold design should be marked on the general map. The weight of the mold is easy to install and safe. The handling of parts above 20 kg should have lifting handling measures to reduce the labor intensity. It should be convenient and safe when assembling and disassembling the mold parts, avoiding the possibility of pinching or cutting hands; the mold should be easily disassembled and stored.
