How to determine the stamping direction of the automobile stamping parts?

The stamping part is a production technology that makes the sheet material directly deformed and deformed in the mould by means of the power of conventional or special punching equipment, so as to get certain shape, size and performance of the product parts. Sheet material, mould and equipment are the three elements of stamping. Stamping is a metal cold deformation processing method. Therefore, it is called cold stamping or sheet metal stamping, short for stamping. It is one of the main methods of metal plastic processing (or pressure processing), and it is also part of the material forming engineering technology.

50 to 60% of the steel in the world are made of plates, most of which are made of stamped products. Body, car radiator, boiler drum, vessel shell, motor, electrical appliances such as core sheet stamping processing. There are also a large number of stamping parts in instruments, household appliances, office machines, storage containers and other products. Stamping is efficient production measures, adopt compound die, anomaly is a multi position progressive die stamping technology, can complete the multi-channel operation in a press, complete the automatic generation of materials. Generate speed, rest time, production cost is low, the collective per minute production by hundreds, many processing plants like.

The stamping parts of automobile have the characteristics of thin, uniform, light and strong. This stamping can be produced from proficient size is difficult to manufacture with reinforced rib, rib, twisting or workpiece flanging, to improve its rigidity. Rong Zhi automotive stamping part indicates that because of rejecting the rough mold, the workpiece accuracy can reach micron level, and the accuracy is high and the specification is identical, so that it can punch holes, convex tables, etc. In the actual production, the common process tests similar to the stamping process are used, such as the deep drawing performance test, the bulging performance test and so on, to check the stamping performance of the material, so as to ensure the quality and the qualified rate of the finished products.

In addition to stamping press forming plate is equipped with water, usually take the stop press. In this world of high-speed multi station press stagnate as the focus, set the equipment configuration, the finished book still collected, and walks mold library and quick die change place, and use the computer program control, can be composed of high productivity high passive stamping production line.

The stamping direction is to determine the parts stamping process must first encounter problems, it not only decides whether a satisfactory tensile stamping, but also affects the number of addendum and binder shape. The following 3 aspects should be met to determine the stamping direction of the stamping parts reasonably, and the automobile stamping parts are analyzed.

It is possible to ensure that the punch can enter the die.

Make the punch contact the blank with large area. The larger the contact surface, the smaller the angle between the contact surface and the horizontal plane. The less the partial stress overload occurs, the more the blank is broken. When the material is stretched, the performance of the mold is improved and the complete shape of the punch can be easily obtained, which is beneficial to the improvement of the deformation degree of the parts.

The surface pressure feeding resistance to uniform and reliable. The depth is main condition to ensure the uniform pressure of each part of the burden of uniform and reliable feeding resistance. The pressure of each part surface feeding resistance is to ensure uniform stamping without wrinkling and cracking of the important guarantee.
