Pay attention to the maintenance of metal stamping parts after installation

Stamping part is a forming and processing method of the workpiece (stamping part) with the required shape and size by applying external force to the plate, strip, pipe and profile by the press and die to produce plastic deformation or separation. Stamping and forging belong to plastic processing (or pressure stamping processing), collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Compared with castings and forgings, stamping parts are thin, uniform, light and strong. Stamping can produce workpieces with stiffeners, ribs, undulations or flanging that are difficult to manufacture by other methods, so as to improve their rigidity. Due to the use of die, the workpiece accuracy can reach micron level, with good repetition accuracy and consistent specifications. It can punch holes, sockets, bosses, etc. Cold stamping parts are generally no longer cut, or only need a small amount of cutting. The precision and surface state of hot stamping parts are lower than those of cold stamping parts, but they are still better than castings and forgings, and the amount of cutting is less. Stamping is a new production method. Using compound die, especially multi station progressive die, multiple stamping processes can be completed on one press to realize full-automatic production from strip uncoiling, leveling, blanking to forming and finishing. Production, good working conditions and low production cost. Generally, hundreds of pieces can be produced per minute

points needing attention in the maintenance of metal stamping parts:

metal stamping parts refer to parts processed by stamping, bending, stretching and other means. A general definition is - parts with constant thickness in the processing process. Metal stamping parts are widely used in various industries in our life, including some electronic devices, auto parts, decorative materials and so on

in addition to forming thick plates with water press, mechanical press is generally used for stamping equipment. Conveying machinery, die warehouse and die changing device, and controlled by computer program, can form an automatic stamping production line with high productivity. When dozens or hundreds of metal stamping parts are produced per minute, the processes of feeding, stamping, parts out and waste discharge are completed in a short time, which often leads to personal, equipment and quality accidents

therefore, stamping production is a very important problem. In the stamping process of general workpieces, due to the rapid rise of temperature in the stamping process, especially in the cold forging stamping process, lubricate the products. If the parts are directly stamped without lubrication, welding assembly, and the parts without oil on the surface are convenient for welding and assembly
