The stamping parts processing design rope ruler is as follows: First, the stamping parts designed must meet the application and technical functions of the product, and they must be assembled and repaired at will; then they must be conducive to improving the utilization rate of metal materials, adding the types and specifications of materials, as much as possible. It can reduce the cost of data, and use low-cost materials under allowable conditions to make the parts as waste-free and less waste as possible; then the design time frame must be complicated and the structure should be reasonable, which is conducive to simplifying the mold The structure simplifies the number of processes, that is, the smallest and most complex stamping process is used to complete the processing of all parts, which is conducive to the stamping operation, facilitates the organization of mechanized and automated consumption, and improves the leisure consumption rate. Designed stamping parts, under the guaranteed normal application conditions, try to make the dimensional accuracy grade and appearance roughness grade as low as possible, and it is conducive to product communication, adding waste products, and guaranteeing product quality fluctuations. The designed stamping parts should be conducive to the use of existing equipment, process equipment and process flow to stop processing, and is conducive to the extension of the application life of the die.
The stamping parts processing products are rich in variety and complicated in appearance, and some undesirable phenomena often occur during stamping consumption. How to avoid the occurrence of results? Shaanxi Heavy Automobile combined its own theory and made a futile search.
The two-end surface protection bracket is the crux of the entire instrument panel assembly of the automobile cab and is a main part to ensure the shake and reliable operation of various instruments of the automobile. Due to the high-speed change of the high-power generator and the harsh driving conditions of the vehicle, strong vibrations and shakes are randomly formed on the cab, which constitutes the instrument circuit in the front control panel and part of the function is disconnected or lost. Therefore, the two-sided surface protection bracket must be able to withstand the effects of impact, circuitous fatigue load and torque, so it must have sufficient bending strength, shear strength and good toughness. In addition, assuming that the part exceeds the allowable stress during forming, the micro-cracks may expand to a certain extent, thereby causing tearing or tilting, which will not only waste the material, but also put the mold in eccentric load and slow down the aging of the mold.
The principle of stamping parts processing is as follows: the stamping parts prepared at the beginning must satisfy the application and technical function of the product, and they must be assembled and repaired at will; then it must be conducive to improving the application rate of metal materials and reducing the variety and specifications of materials. Although the consumption of materials is low, and low-cost materials are used when allowed, even if the whole machine is waste-free and less wasteful; then the appearance must be simple when cooking, and the planning must be reasonable. How conducive to simplification The planning of the mold simplifies the number of processes, that is, the smallest and simplest stamping process is used to complete the processing of the entire machine, which is conducive to stamping control, facilitates the planning and completion of mechanized and automated consumption, so as to increase the labor consumption rate. For the stamping parts of the cooking, in the case of abnormal application conditions, although the dimensional accuracy grade and the outer roughness grade are required to be lower, it is conducive to product exchange, reducing waste, and ensuring stable product quality. The processed stamping parts should be conducive to processing even if the existing equipment, process equipment and process flow are used, and it is conducive to the extension of the application life of the die.
Although the processing quality of the workpiece is very important, the protection problems in the operation process should be paid more attention to to avoid unnecessary risks. Next, I will focus on the protective measures in the processing of stamping parts, can they reach the corresponding specifications?
The first is for the protection of the stamping equipment. In order to prevent the operator from being injured by the chipping chips, it is necessary to install a baffle at a suitable position of the equipment. At the same time, the chuck, faceplate and other parts on the stamping equipment must be equipped with secure bolts and ensure their tightening. In addition, the tapered shaft chuck must be equipped with a tie rod to be more guaranteed.
Before stopping stamping, check the working conditions of the equipment, and deal with problems in time if problems are found. The use of protective covers for various parts is indispensable, so as not to twist the clothes and other parts of the body during the operation. In the absence of a protective cover, pay attention to the distance during operation and do not approach it.
There are also some protection requests for operators. Do not open the cuffs during work, and wear protective clothing, protective caps and other protective equipment, but do not wear gloves. When the workpiece in the equipment is changed, stop using an emery cloth to sand the part or use cotton sand to polish the part, and stop using your hand to cut the chips.
