The metal drawing part is a forming processing method that applies external force to the plate, strip, pipe and profile by pressing the die to produce plastic deformation or separation, so as to obtain the required shape and size of the workpiece. Stamping and forging belong to plastic processing, collectively known as stamping blank. It is mainly hot rolled steel plate and steel. Let’s take a look at how to improve the service life of hardware stretching parts.
(1) Before installation and use, the drawing stamping parts should be strictly checked to remove the dirt and check whether the guide sleeve and die of the drawing stamping parts are well lubricated.
(2) When the cutting edge of punch and die is worn, it should be stopped using and grinded in time. Otherwise, the wear degree of die edge will be enlarged rapidly, the wear of die will be accelerated, and the quality and life of die will be reduced.
(3) To ensure the service life of the drawing stamping parts, the spring of the die should be replaced regularly to prevent the spring fatigue damage from affecting the use of the drawing stamping parts.
