Method and device for continuously inlaying precious metal sheets in mold

Abstract

The invention relates to a method and a device for continuously inlaying precious metal sheets in a mold, belonging to the machine finishing technology field. The method comprises following steps: firstly leading the precious metal sheets on the auxiliary material belt and the workpieces on the main material belt to be correspondent in a cross shape in a state to be punched, then directly punchingthe precious metal sheet on the auxiliary material belt into the workpiece on the main material belt by a punch, subsequently buckling parts of the workpieces on the punched precious metal sheets, finally back pressing the projecting part at the back surface of the workpiece through punching. The device is provided with a motor in the punch mold besides the matched feeding device. The working terminal of the motor connects a drive shaft through the gear components. A material belt transferring groove is bridged above the drive shaft. A feed rolling wheel is installed on the drive shaft. A driven pinch wheel is arranged at the lower part of the feed rolling wheel. Thus, the inlaying requirement is met without increasing the size of the product and using the precious metal material on the whole product and an optimal inlaying is implemented at the required part.

Description

technical field [0001] The invention relates to a method and equipment for inlaying products in a mold, in particular to a method and a device for inlaying precious metal sheets in a continuous mold, and belongs to the technical field of mechanical processing. Background technique [0002] In engineering practice and practical application, some key parts of power transmission or electrical equipment need excellent resilience, electrical conductivity or heat transfer, so key working parts need to use materials with good resilience, conductivity or heat transfer (such as stainless steel, Ag, Cu, Al). Prior to this, product design generally adopted the following four schemes: [0003] The first option is to directly use materials with relatively poor performance for the entire product. Although the cost of the product is saved in this way, the quality and performance of the product are sacrificed, and even the use requirements of the product cannot be met. For example, in or...

AI Technical Summary

Problems solved by technology

In the current practical application, various methods of riveting (such as flanging riveting, TOX riveting) including welding require enough space on the product to be used as the riveting point, and the products need to have elements for positioning each other, which requires Increasing the external dimensions of the product to meet these requirements increases the use of product materials and greatly limits the design and layout of the product structure. This solution cannot be used if sufficient space cannot be provided.
