Punching die

Technical Field

The invention relates to the field of dies, in particular to a punching die.

Background

The mould is various moulds and tools for obtaining required products by injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. The element has the name of "industrial mother". The blank is formed into a tool with a specific shape and size under the action of external force. The method is widely applied to blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by applying the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated or combined. When the blank is closed, the blank is injected into the die cavity for forming. The die is a precise tool, has a complex shape, bears the expansion force of a blank, has higher requirements on structural strength, rigidity, surface hardness, surface roughness and processing precision, and the development level of die production is one of important marks of the mechanical manufacturing level.

When punching hole is carried out to circular slice spare part, stamping die also need to be used, generally when punching hole is carried out to circular slice spare part, it places in the punching hole region all directly to hold circular spare part by hand, there is danger so promptly, and can not realize lasting material loading, waste time and energy, and because spare part does not set up fixing device when the punching hole, when punching hole is carried out to the spare part, the condition that the part takes place to misplace or squint still can exist, thereby greatly reduced the punching hole precision of spare part, and sometimes still there is the condition that the spare part of punching press can be taken along with the terrace die together, seriously influence machining efficiency.
