Metal stamping die Maintenance Knowledge 1: You must wear edge mold after prolonged use, the blade grinding surface must be demagnetized, not with a magnetic, or prone to sealing. 2: spring or other elastic parts in the course of the spring most easily damaged, usually a fracture and deformation phenomena. Under the approach taken is to replace, in the replacement process must pay attention to the size and type of springs, metal stamping plant, spring specifications and models of the three confirmed by color, diameter and length, only three are in the same circumstances It can be replaced. 3: Die punch course prone to break, bend and bite a bad phenomenon, punch sets are generally bad bite. Punch and punch sets are generally damaged replacement parts with the same specifications. The main parameters of the punch working portion size, the mounting portion size, length and other dimensions. 4: fasteners, check the fasteners are loose, damaged phenomenon, the approach is to look for the same size of the parts to be replaced. 5: binder components such as pressure plate, excellent strength glue, etc., unloading parts such as stripper plates, pneumatic roof materials. Check all parts of the relationship between time and maintenance parts for damage, metal stamping, repair of damaged parts, pneumatic ejector check for air leaks, and to take measures to specific situations. Such as tracheal damage replacement. Metal stamping parts process first, drawing: the straight pieces of wool or step into a hollow, metal stampings, or further change the shape of the hollow piece suits and size of a stamping process. Drawing temporal core member mainly rely on material located outside the punch die to form the bottom of the inflow. Second, trimming: the use of metal stamping dies trim the edges forming process, so that it has a certain diameter and a certain height or a certain shape of a stamping process. Third, punching: the waste along the closed contour separated from the material or process parts of a stamping process to obtain the required holes in the material or workpiece. Fourth, flanging: along its side around the shape of the curve will be translated into the short side of a stamping process. Fifth, turn the hole: the material around the perimeter of the hole translated into its side flange of a stamping process. Sixth, blanking: material separation along the closed contour of a stamping process, the separated material into the workpiece or the process pieces, most of planarity. Seventh, plastic: relying on material flow, a small amount of change in step shape and size, in order to ensure precision parts stamping process of metal stamping parts | metal stamping | Chen Feng Hardware (Views) provided by the Dongguan City Hardware Products Co., Ltd.
