Sectional characteristics of precision stamping parts 'Hardware'

When many customers make an inquiry, after the drawings are sent, the cross-sections of the precision stamping parts on the drawings are generally drawn as vertical planes straight up and down. This is also done by the designer for convenience, but we are the precision The metal stamping factory must confirm with the customer again at this time. When explaining to the customer, you must tell the customer the cross-section of the precision stamping part. What are the characteristics of the cross-section of the precision stamping part? Panda will give you a detailed explanation below. One, rounded corners. The rounded belt is also called the collapsed corner, which is caused by bending and stretching of the surface of the steel plate close to the upper die or lower die but not in contact with the stamping die; Second, the bright belt. The bright band is produced when the upper die cuts the steel plate and the material is squeezed into the lower die to produce plastic and shear deformation. The bright band is an area with good cross-section of the metal stamping parts. The light is flat and perpendicular to the plane of the steel plate. Precision stamping is generally the bright belt pursued. Third, the fault zone. The surface of the fracture zone is relatively rough and has an inclination of about 5 degrees, which is caused by the expansion of cracks formed during punching. Four, glitches. The burr is close to the edge of the fracture zone, and the position of the crack is not directly facing the knife edge of the die, but on the side close to the knife edge of the stamping die. It will be aggravated when the precision stamping part is pushed out of the die by the lower die. The section of a good precision stamping part should first control the burr, remove the burr, and then pursue the bright band.
