Description

Technical Field

[0001] This utility model relates to the field of connector metal shell forming machine technology, and in particular to a connector metal shell forming machine. Background Technology

[0002] As electronic devices develop towards miniaturization and high performance, connectors, as key components for achieving electrical connections, have a significant impact on the overall performance, reliability, and assembly accuracy of the equipment due to the quality of their shell molding. The metal shells of electrical connectors are generally produced through continuous stamping technology to form specific shell shapes.

[0003] In existing technologies, the metal shell forming of electrical connectors is generally carried out using automated equipment. For example, a bending and shaping equipment includes a cabinet with a turntable mounted on it. A fixture is mounted on the turntable, and a feeding component, a discharging component, a rejection component, and a bending component are arranged around the turntable. By setting a fixture on the turntable, the connector shell is positioned and fixed by the fixture, and then the feeding component, discharging component, rejection component, and bending component are used for automatic feeding, discharging, and bending, thereby achieving automated integrated processing. However, the rationality of the arrangement of its various functional parts on the equipment is still not ideal. Due to the large number of workstations, a turntable with a large outer diameter is required. When the feeding component, discharging component, rejection component, and bending component are arranged on the machine table along the circumference of a turntable, the entire processing equipment becomes larger, requiring a large amount of space. This results in the entire processing equipment occupying a large space in the workshop, which is not conducive to workshop layout and management.

[0004] Therefore, a new technical solution needs to be researched to address the above problems. Utility Model Content
