Abstract

The invention relates to a punching and riveting device of a combined connecting movable sheet used on a hinge. The device comprises a fixing mold base, an upper mold and a lower mold. Three punching needles, two riveting hole punch needles and a pair of shear type punches are respectively arranged at the front end of the upper mold. A perforation is arranged in the middle of the upper mold, a slider is arranged on the perforation, and two separation punch needles with elastic elements are mounted below the slider. A forming punch is arranged at the back end of the upper mold. A control system is arranged on the upper mold and is connected with a connection power rod. The lower mold is provided with perforations corresponding to the upper mold punching needles, the riveting hole punch needles, the shear type punches, the separation punch needles and the forming punch. Two or more than two movable ejector pins with the elastic elements are distributed on the lower mold plate. The perforation corresponding to the forming punch is arranged on the lower mold. A returned material device is arranged above the lower mold. The invention integrates the punch processing and the riveting processing for the connecting movable sheet on the hinge, greatly reduces the processing time, and greatly improves the processing efficiency and saves the production cost.

Description

technical field [0001] The invention relates to a stamping and riveting method and device for a combined connecting movable piece used on a hinge. technical background [0002] At present, the existing stamping and riveting methods for combined hinge joints are all hinge joints stamped and then manually riveted. This original manual riveting method is not only inefficient, but also likely to cause defective products or Waste products greatly affect the efficiency and cost of production, which is not conducive to the development mode of modern industry. Contents of the invention [0003] In order to solve the defects of low production efficiency and unfavorable mode of industrial development in the prior art combined hinge connecting piece punching and riveting method, a method of stamping and riveting the combined hinge connecting piece formed by stamping and riveting is provided. mold. [0004] The mold includes: a fixed mold base, an upper mold and a lower mold. There...
