Abstract

The utility model discloses an upper stamping device for a stamping die. The upper stamping device comprises a stamping head, an intermediate rod and a mounting end which are integrally formed, wherein a plurality of inner holes penetrate through the whole upper stamping device; an exhaust groove is formed in the mounting end; and an opening of each inner hole in the mounting end is formed in the exhaust groove. The exhaust groove is formed in the mounting end of the upper stamping device; and when the upper stamping device is arranged on a press for carrying out stamping production, an air exhausting channel is formed from the inner holes to the exhaust groove. The arranged exhaust groove has little influence on the strength of the mounting end; and meanwhile, exhaust holes in the intermediate rod are omitted, so that the strength of the intermediate rod is ensured and the possibility of cracking or breakage in the stamping use process is reduced.

Description

A kind of upper punch of diel
Technical field
The utility model relates to a kind of metal stamping die, particularly relates to a kind of upper punch of metal stamping die.
Background technology
Punching press is at room temperature, utilizes the mould that is installed on the forcing press that material is exerted pressure, and makes it produce separation or plastic deformation, thereby obtains a kind of pressure processing method of required part.The diel that material production is separated generally has been designed to inner hole structure, and endoporus is the design that through hole is arranged on the product.In the punching production process, plug fluctuates in endoporus and can produce one gas with the mould of endoporus, and the power of this strand gas makes mould produce sizable power, makes the mould can't the demoulding.Therefore the mode that generally adopts now is to get out steam vent at the endoporus hole wall.At hole wall the exhausting problem that steam vent can solve diel is set, but, when the diel profile less, when interior hole number is more, the endoporus hole wall that to have brought a problem be exactly this type of mould is thinner, offer steam vent so that the intensity of whole diel significantly reduces at each endoporus hole wall, cause mould in the punching press use procedure, to form crack or bending fracture in the perforate side easily.
The utility model content
The purpose of this utility model provides that a kind of profile is little, the upper punch of the diel of many endoporus, and the exhausting problem of mould and guarantee that the intensity of diel is unaffected when solving punching press is difficult for occuring crack or fracture in punching press is used.
The technical solution of the utility model is such: a kind of upper punch of diel, comprise integrated drift, king-rod and installation end, some endoporus run through whole upper punch, it is characterized in that: described installation end is offered an air discharge duct, and described endoporus is arranged in the air discharge duct at the opening of installation end.
In order to be punched on guaranteeing in the punching course, installation end and forcing press have enough contacts area and installation end itself not to bend, and described air discharge duct cross section is rectangle, air discharge duct degree of depth 1-2mm.
The advantage of technical scheme provided by the utility model is that the installation end of upper punch is offered air discharge duct, when upper punch is installed on forcing press and carries out punching production, forms an air discharging channel from endoporus to air discharge duct.The air discharge duct of offering affects the intensity of installation end hardly, owing to cancelled the steam vent on the king-rod, king-rod intensity is guaranteed simultaneously, is difficult for occuring crack or fracture in punching press is used.
Description of drawings
Fig. 1 is the cutaway view of many endoporus of the medium and small profile of prior art upper punch;
Fig. 2 is cutaway view of the present utility model;
Fig. 3 is upward view of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with embodiment, but not as to restriction of the present utility model.
As shown in Figure 1 and Figure 2, in the prior art, little many endoporus of profile upper punch comprises by integrated drift 1, king-rod 2 and installation end 3 after the mold materials milling, some endoporus 4 run through whole upper punch, hole wall at the endoporus 4 of king-rod 2 is drilled with steam vent 5, and the endoporus Air is discharged from clapping steam vent 5 when upper punch is worked like this.And structure of the present utility model is to have cancelled the steam vent 5 on the king-rod, offers an air discharge duct 6 in the installation end 3 usefulness lines cutting of upper punch, and the cross section of air discharge duct 6 is rectangular, air discharge duct degree of depth 1-2mm.In conjunction with shown in Figure 3, form an air discharging channel from endoporus to air discharge duct.The air discharge duct of offering affects the intensity of installation end hardly, owing to cancelled the steam vent on the king-rod, king-rod intensity is guaranteed simultaneously, is difficult for occuring crack or fracture in punching press is used.
