Abstract
Description
Technical Field
[0001] The invention relates to the field of mold processing, in particular to a connector shell processing method using a continuous mold and a processing device thereof. Background Art
[0002] The existing connector shell is a stretched hardware (product to be processed), which often adopts the production mode: continuous die cold punching and stretching process or single process mold production. The continuous die cold punching and stretching process is such as the technical solution listed in the public document CN106238572B, but the closed thickness of the stretched hardware manufactured by the continuous die cold punching and stretching process is uneven, resulting in limited shape of the formed shape. Only a single shape can be formed, and complex shapes are difficult to achieve. The shape of the connector shell is relatively complex, so the connector shell is generally processed by a single process mold, but the single process mold production first needs to rely on a manual single engineering mold to complete a single process, such as a flanging process, and then through a combination of multiple molds (secondary flanging, folding and other process processing) to complete the entire stretching hardware processing. Obviously, the single-process mold production method affects the processing efficiency when each process is completed and the next set of molds is transferred by manual or mechanical hands. Each time a set of molds is transferred, they need to be repositioned. Repeated positioning of multiple sets of molds will cause large positioning errors, affecting the molding accuracy of the product. The stretching processing method of multiple sets of molds will inevitably lead to inconvenience in subsequent processing, making the product unevenly stressed during the processing, prone to bursting, and increasing the product defect rate. That is, the traditional connector shell processing and production speed is slow, the efficiency is low, and the product volume is small. Multiple sets of molds are required for simultaneous production, and the manpower and machine costs are very high.
[0003] A continuous die refers to a cold stamping die in which a press machine uses a strip of material to complete multiple stamping processes simultaneously on a die using several different workstations in one stamping stroke. Each time the die completes a stamping, the material moves a fixed distance until the finished product is completed. The finished product refers to a single hardware part, and the connector housing requires a stretching process and cannot automatically enter the continuous stamping die.
[0004] The inventor has been deeply engaged in the field of hardware processing for decades. How to combine single-process molds and continuous molds to achieve continuous processing of connector shells. Single-process mold production requires manual or robotic arms to take between multiple single-process molds. Robots are used instead of manual labor, and the cost of robots is high. Stretched hardware cannot be automatically fed in continuous molds. The inventor pondered how to combine continuous molds and single-process molds to achieve continuous production of connector shells, which is an urgent problem to be solved in this invention. Summary of the invention
