A die capable of forming several holed carbide products by one punch and its installation method

Abstract

The invention discloses a mold capable of molding multiple hole-carried products through once punching. The mold is characterized in that one of an upper punch and a lower punch is provided with multiple core rod holes; multiple core rods are slidingly matched with the corresponding core rod holes; T-shaped end parts at one ends of the multiple core rods are matched in corresponding T-shaped grooves of core rod transfer pieces; and the other ends, opposite to one ends with the T-shaped grooves, of the core rod transfer pieces are fixed on a core rod mounting base of a press. The mold is simple in production, convenient for installation, wide in application range and higher in popularity, and solves the technical difficulty of more automatic pressing molding of the hole-carried products.

Description

technical field [0001] The invention relates to a mold capable of forming several products with holes in one stamping, especially a cemented carbide mold, especially an automatic pressing molding mold with multiple holes of cemented carbide blades, which solves the problem of hard alloy strips. The technical problem of many products with holes can improve the pressing efficiency of products with holes. Background technique [0002] Cemented carbide inserts are sintered from powder after being pressed into shape by a press loaded with a mould. In order to improve the pressing efficiency, many cemented carbide manufacturers have also developed many automatic pressing molds for many cemented carbide products. However, such one-out multi-tungsten carbide molds are concentrated on cemented carbide products without positioning holes, such as buttons, bars, etc. Products with holes such as cemented carbide turning blades are still the traditional one-out-one way of suppression. ...

AI Technical Summary

Problems solved by technology

[0005] 1. Grooving in the lower punch has caused damage to the punch. During the pressing process, the punch is easily deformed and its life is not long;

[0006] 2. The stroke of the punch is limited, because the beam and fork that fix the core rod are in the groove, the height of the punch out and the height of the pull-down are limited, which is very unsafe

[0007] 3. It is inconvenient to load and unload the mold

[0008] 4. The content of mold processing has increased, and each set of molds needs to be slotted and made for positioning beams and plugging, etc.

[0009] 5. The versatility is not strong, it is only suitable for square hard alloy products, such as square flat plates

[0010] 6. The core rod connection method has too many limitations
