Stamping die and workpiece stamping method

Abstract

The invention discloses a stamping die and a workpiece stamping method. The stamping die comprises a die body and a bending component, the die body comprises an upper die body and a lower die body, a plurality of groove pressing cutters are arranged on the bottom face of the upper die body, a plurality of supporting parts used for supporting a workpiece are arranged on the top face of the lower die body, and the groove pressing cutters are arranged corresponding to the supporting parts correspondingly; the groove pressing cutters are located above the corresponding supporting parts, and a deformation space capable of allowing the workpiece to be pressed in is formed between two adjacent supporting parts; the bending component is arranged on the die body and used for exerting pressure on the workpiece so that the parts, located at the two sides of the groove pressing cutter, of the workpiece can be bent downwards and pressed into the deformation space. The workpiece is placed on the supporting part, the groove pressing cutters of the upper die body is inserted into the workpiece, and meanwhile, under the action of the bending component, the parts, located at the two sides of the groove pressing cutters, of the workpiece are bent downwards to be pressed into the deformation space, so that the stability of indentation is improved, the extension controllability of the indentation is good, and the forming effect of segmentation grooves is good.

Description

technical field [0001] The invention relates to a stamping die and a workpiece stamping processing method in the technical field of stamping. Background technique [0002] Ceramic substrates are the main substrates used to form electronic components such as chip resistors, potentiometers, integrated circuits, and thick film circuits. The manufacturing process of ceramic substrates is generally to prepare ceramic powder with organic substances such as binders, dispersants, and plasticizers to form a slurry, and then cast to form ceramic green sheets. The ceramic green body is then punched with a metal stamping die and the process of forming a dividing groove. The punching can form a predetermined shape of the ceramic green body, and the dividing groove is formed by pressing the blade configured on the stamping die into a predetermined depth. Afterwards, the ceramic green body is pre-fired at a certain temperature to remove the organic binder therein. Finally, a dense cerami...

AI Technical Summary

Problems solved by technology

During the use of existing stamping dies, there will be problems such as excessively large arc angles during cutting and excessively large split groove angles, which cannot ensure proper crack extension.
