Embodiment Construction

[0017] Figures 1 and 2 are the layout of the parts on the material belt and the side view of the formed stacked riveting workpiece. Figures 3 and 4 are the general assembly drawings of the upper mold, and Figures 5 and 6 are the general assembly drawings of the lower mold. The mold adopts two-way guide pillars for precise guidance , the stepping direction is the guiding and positioning of the guiding nail, which creates conditions for correct riveting. The specific structure is: the cylinder is connected to the mold, a relay is installed on the punching machine, the punching machine works eight times as a cycle, the first stamping, the cylinder works once to push the wedge-shaped slider to work to achieve punching, and pull the wedge-shaped slider to quickly return to its original position . The last seven stamping cylinders do not work, which is the stamping and convex process, and the eight parts are completed in the cavity of the three-punch concave model shown in the figur...

Abstract

An automatically overlapping and riveting technology for at most 8 punched workpieces features use of a cascade die set with the first working position for alternatively punching hole and lug, and the second working position for blanking. Its technological steps includes punching hole on the raw band, punching lug, punching for blanking while pressing it in riveting die, and so on.

Description

technical field [0001] The invention belongs to metal stamping processing methods, in particular to an automatic stacking and riveting processing method for stamping parts. Background technique [0002] At present, electronic products and instruments need to use matching metal stamping parts, and some also need to use multiple stamping parts and then riveted into a whole part of the product. At present, the stamping parts are generally stamped out of the metal strip first, and then riveted. There are many processes in this way, and turnover between processes is required, which not only wastes man-hours, but also the quality of processed products cannot meet the technical index requirements of supporting products. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an automatic riveting processing method for stamping parts. It needs to be stamped and then riveted into parts, and the progressive die is connected with...
