Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, specifically a stamping equipment for preparing and processing silver-based contacts. Background Technology

[0002] Silver-based contacts are key components in electrical switches, relays, and other power equipment, and their quality directly affects the conductivity and service life of the equipment. Stamping is a crucial step in the manufacturing process of silver-based contacts, requiring a stamping device to process the silver-based raw materials into contact products of specific shapes and sizes. Currently, existing silver-based contact stamping devices have several shortcomings. Firstly, most employ a single stamping structure, resulting in low positioning accuracy of the raw material during stamping, easily leading to dimensional deviations in the stamped contact products and affecting product quality. Secondly, the stamping device has poor buffering performance, resulting in significant impact forces between the punch and the worktable during stamping, which can damage the equipment, reduce its service life, and potentially cause defects such as cracks in the silver-based contacts. Furthermore, existing stamping devices are inconvenient for collecting and processing waste material after stamping; waste accumulation not only affects the working environment but may also interfere with subsequent stamping processes. To address these issues, a new stamping device for the manufacturing and processing of silver-based contacts is proposed. Utility Model Content
