There are coups to prolong the service life of drawing stamping parts

Stretch forming is a stamping process in which a flat plate is formed into an open hollow part using a processing method. As one of the main processes of stamping, drawing has been widely used. The stretching process can be used to produce thin walls with irregular shapes such as cylindrical, rectangular, trapezoidal, spherical, conical, and parabolic shapes. If combined with the stamping process of other metal stamping parts, parts with more complicated shapes can also be manufactured. Now stretch stamping parts are widely used in all areas of our lives. If you want to properly extend the service life of stretch stamping parts, we need careful maintenance to achieve it. So, what issues should be paid attention to during maintenance? 1. The drawing stamping parts should be strictly inspected before installation and use, and the dirt should be removed, and the guide sleeves and molds of the stamping parts should be carefully checked for good lubrication. 2. According to the installation steps of the die, install the die and die on the turntable to ensure that the direction of the die and the die are the same, especially the required direction (non-circular and square) stamping parts should be larger. Take care to prevent assembly errors and backlash. 3. When the edge of the punch and die of the stamping part is worn, stop using it and grind it in time. Otherwise, the degree of wear on the edge of the die will rapidly expand, the wear of the die will be accelerated, and the quality of stamping parts and the life of the die will be reduced. 4. Regularly check the turntable of the punch and the mold mounting base to ensure the coaxial accuracy of the upper and lower turntables. 5. The molder should use softer metals (such as copper, aluminum, etc.) to make operating tools when installing the mold, so as not to damage the stretched parts during the installation process. 6. To ensure the service life of the drawing stamping parts, the spring of the mold should be replaced regularly to prevent the fatigue damage of the spring from affecting the use of the drawing stamping parts. The service life of drawing stamping parts depends on reasonable mold structure, superb manufacturing accuracy, good heat treatment effect and correct selection of punches, drawing stamping parts installation accuracy and other factors, the correct use, maintenance and maintenance of molds are also A link that cannot be ignored, so we must eliminate the adverse effects of various factors on the service life of drawing stampings, and take effective measures to improve its service life.
