Abstract
The invention discloses a punching die for a punched sheet. The die comprises an upper die and a lower die, wherein the lower die is fixed on a lower base plate through a screw; a leakage hole is formed in the lower base plate; the lower die is provided with a cutting edge and a punching female die; a notch is formed on the cutting edge along a cutting edge circle and has a circular arc structure; and the punched sheet moves out of the lower die through the notch. The conventional complex structure of the punching die for the punched sheet is eliminated, and the structure of the die is simplified, so that the die is easy to manufacture and assemble, the phenomenon that the punched sheet is scrapped because a top block fails is radically avoided, and the quality reliability of a product is high.
Description
Technical field
The present invention relates to a kind of Lamination mould, especially relate to a kind of punching jet-bedding mould.
Background technology
Existing jet-bedding is held concurrently in the peel of mould structure, the die of cutting blade part uses jacking block, spring, pressing plate and bolt structure, and difficulty of processing is big, assembly precision requires high, difficulty is installed, in use, often because reasons such as manufacturing, assemblings, cause jacking block to lose efficacy, make punching scrap phenomenon and happen occasionally, influence is produced, and product quality reliability is poor.
Summary of the invention
The object of the present invention is to provide a kind of punching jet-bedding mould, it has simple in structure, is easy to assembling, is convenient to separate punching and safe and reliable characteristics.
The objective of the invention is to be achieved through the following technical solutions:
A kind of punching jet-bedding mould, it comprises upper die and lower die, offers cutting blade cutting edge and lower die on the described counterdie, and wherein, described cutting blade cutting edge place offers a breach along the cutting blade circle, and punching is shifted out counterdie through breach.
Especially, described breach is shaped as circular arc.
Beneficial effect of the present invention is that the counterdie of described punching jet-bedding mould is offered place's arc gap in cutting blade cutting edge place along the cutting blade circle, make punching shift out counterdie, cancel original labyrinth, simplify mould structure along arc gap, make the mould manufacturing, the assembling simple, product quality reliability is good.
Description of drawings
With embodiment the present invention is described in further detail with reference to the accompanying drawings below.
Fig. 1 is the vertical view of the counterdie of punching jet-bedding mould of the present invention;
Fig. 2 is the profile of the counterdie of punching jet-bedding mould of the present invention.
Among the figure:
1, lower bolster; 2, lower die; 3, cutting blade cutting edge; 4, breach; 5, screw; 6, counterdie; 7, material spilling hole.
The specific embodiment
Please refer to Figure 1 and Figure 2, Fig. 1 is the vertical view of the counterdie of punching jet-bedding mould of the present invention; Fig. 2 is the profile of the counterdie of punching jet-bedding mould of the present invention.
In present embodiment, described punching jet-bedding mould, it comprises patrix (not illustrating among the figure) and counterdie 6, described counterdie 6 is fixed on the lower bolster 1 by screw 5, offer material spilling hole 7 on the described lower bolster 1, offer cutting blade cutting edge 3 and lower die 2 on the described counterdie 6, described cutting blade cutting edge 3 places offer a breach 4 along the cutting blade circle, described breach 4 is an arc-shaped structure, and punching is shifted out counterdie through breach 4.
The counterdie 6 of above-mentioned punching jet-bedding mould is in cutting blade cutting edge 3 places, offer place's arc gap 4 along the cutting blade circle, make punching shift out counterdie along arc gap 4, cancel original labyrinth, simplify mould structure, make mould manufacturing, assembling simple, thoroughly stop because of the jacking block phenomenon that punching is scrapped that lost efficacy takes place, product quality reliability is good.
Claims (2)
