Abstract
A powder metallurgy forming mandrel relates to the field of powder metallurgy, in particular to a mandrel of a die. The powder metallurgy forming mandrel comprises a mandrel head made of tungsten carbide and a connecting rod made of medium carbon steel, the center of the lower end of the mandrel is equipped with a groove, the upper end of the connecting rod is fixed with a boss, and the boss is in threaded connection into the groove. Through the design, the mandrel head of the mandrel is in threaded connection with the connecting rod, a forming portion of each mandrel is solid and can bearing extremely high external force during a mass production process, and then problems caused by repair or scrap caused by cracking, thereby saving cost and prolonging service life of the mandrel.
Description
Technical field
The utility model relates to field of powder metallurgy, relates in particular to a kind of plug of mould.
Background technology
Usually mould is made up of punch, die and plug etc.; plug is arranged in the centre bore of punch, die; the groundwork section of plug is an epimere; need bear bigger external force; and the epimere inboard of existing plug is provided with counterbore, and every plug is in a large amount of production processes, and the stressed root that causes in the counterbore outside ftractures; need shutdown maintenance, cause equipment to stop work and the increase maintenance cost.
The utility model content
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of powder metallurgy shaping plug of long service life to be provided.
The purpose of this utility model is achieved in that powder metallurgy shaping plug, comprise core head of making by tungsten carbide and the extension bar of making by medium carbon steel, center, described core head lower end is provided with groove, the upper end fixing lug boss of described extension bar, and described boss is threaded in the groove.
The beneficial effects of the utility model are: by above design, the core head of plug is threaded with extension bar, the shaping of every plug is an entity, in a large amount of production processes, can bear very big external force, solved the problem of keeping in repair or scrapping because of cracking, thereby saved cost, and prolonged the service life of plug.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Among the figure, 1 core head, 2 boss, 3 grooves, 4 extension bars.
The specific embodiment
As shown in Figure 1, be powder metallurgy shaping plug, comprise core head of making by tungsten carbide 1 and the extension bar of making by medium carbon steel 4, the center, lower end of core head 1 is provided with groove 3, the upper end fixing lug boss 2 of extension bar 4, boss 2 is threaded in the groove 3, makes core head 1 be threaded with extension bar 4.Because the shaping of every plug is an entity, does not exist because cracking and maintenance or scrap, thereby saved cost, and prolonged the service life of plug.
Claims (1)
1. powder metallurgy shaping plug comprises the core head made by tungsten carbide and by the extension bar that medium carbon steel is made, it is characterized in that: center, described core head lower end is provided with groove, the upper end fixing lug boss of described extension bar, and described boss is threaded in the groove.
