Abstract

The utility model provides a punching hole mesh anti-wrinkle device which is characterized in that a plurality of subsidiary holes are added at a position which is kept a suitable distance to the side of a primary hole of the base mould of a punching hole mould. When another punching operation of punching holes of punching materials is carried out, and metal plate burrs generated by a prior punching are placed into the subsidiary holes to enable a metal plate to be kept in horizontal. Winkles generated from extrusion of the metal plate during the punching operation are avoided. Punching quality of a punching hole mesh is ensured.

Description

Punching net is prevented the crape device

Technical field

The utility model refers in particular to a kind of metallic plate strikes out predetermined mesh at the board mould anti-crape method relevant for the anti-crape device of a kind of punching net.

Background technology

General punching net plant equipment is inserted the banded material of a metallic plate on the uniform poroid mould, and consecutive mean send part, is stamped to form.In the punching course, if adopt single side by side line mould, do the action of punching press, its drawing velocity is slow, cost of manufacture is higher; Therefore the insider adopts many row's line moulds, does the action of punching press, although speed, the burr (burr) that produce during because of the punching net punching are extruded, and makes the object of punching net produce wrinkle, causes the product of punching net bad, thereby haves much room for improvement.

In view of this present utility model people based on being engaged in the industry experience for many years, studies intensively and repeatedly test improvement, nowadays finally creates the anti-crape device of a kind of Novel flushing hole pattern, can remove product shortcoming commonly used, promotes effect.

The utility model content

Main purpose of the present utility model is to provide a kind of punching net to prevent the crape device, mainly be to set up a plurality of secondary holes at the positive hole of continuous punching casement bed die (counterdie) side, when next time punching operation is carried out in metallic plate feeding punching, this pair hole can prevent that one-off hole-piercing produces before the metallic plate burr (burr) are extruded and produce wrinkle, guarantee to protect the punching quality of punching net.

Realize that the above-mentioned purpose technological means is as follows: a kind of punching net is prevented the crape device, establish a plurality of positive holes on the perforating die bed die, metallic plate places on the bed die, and the mould of perforating press patrix is done the punching press action downwards, with the metallic plate punching, a plurality of secondary holes are established in the side appropriate position in the positive hole of bed die.

Symbol description

10 bed dies, 11 positive holes

12 secondary holes, 20 patrixes

21 moulds, 30 metallic plates

31 slashings pieces, 32 burr

The specific embodiment

The below describes embodiment of the present utility model in detail, and the example of described embodiment is shown in the drawings, and wherein identical or similar label represents identical or similar element or the element with identical or similar functions from start to finish.Be exemplary below by the embodiment that is described with reference to the drawings, only be used for explaining the utility model, and can not be interpreted as restriction of the present utility model.

See also shown in Figure 1, the schematic appearance of the anti-crape device perforating die bed die (counterdie) 10 of the utility model punching net.Shown in the local A of Fig. 2, be provided with a plurality of positive holes 11 on this perforating die bed die 10, cooperate Fig. 3 and shown in Figure 4, when metallic plate 30 places on the perforating die bed die 10, when the mould 21 of perforating press patrix 20 is done the punching press action downwards, the slashings piece (waste material) 31 that is punched down on the metallic plate 30 can drop in the positive hole 11 of bed die 10, and the metallic plate 30 punching limits that were stamped can produce burr (being burr) 32; The side appropriate position in bed die 10 positive holes 11 is provided with a plurality of secondary holes 12, as shown in Figure 4, when next time punching operation is carried out in the feeding punching, the burr (being burr) 32 that this pair hole 12 can be used for one-off hole-piercing before the metallic plate is produced are inserted, make metallic plate 30 keep horizontal always, can avoid metallic plate 30 to be extruded and produce wrinkle, guarantee the punching quality of punching net.

The secondary hole 12 of whole row on the perforating die bed die (counterdie) 10 is positioned at the interval in the positive hole 11 of whole row, and the various arrangement state is arranged; As shown in Figure 5, the secondary hole 12 of bottom row second from the bottom is between the positive hole 11 of upper and lower row.As shown in Figure 6, first, second arranged the top in positive hole 11 bottom the secondary hole 12 of bottom row third from the bottom was positioned at.As shown in Figure 7, the bottom fourth from the last is arranged the top that secondary hole 12 is positioned at the positive hole 11 of first, second, third row, bottom.

In sum, the utility model punching net is prevented the crape device, mainly be to set up a plurality of secondary holes in the suitable distance of the positive hole of perforating die bed die side, when metallic plate feeding punching, the burr that front one-off hole-piercing produces (being burr) can fall within the secondary hole, can prevent that metallic plate is extruded and produces wrinkle, guarantees the punching quality of punching net.

Embodiment shown in above foundation is graphic describes structure of the present utility model, feature and action effect in detail; the above only is preferred embodiment of the present utility model; but the utility model does not limit practical range with shown in the drawing; every change of doing according to conception of the present utility model; or be revised as the equivalent embodiment of equivalent variations; when not exceeding yet specification and illustrating contain spiritual, all should be in protection domain of the present utility model.

Claims

1. a punching net is prevented the crape device, and be primarily characterized in that: establish a plurality of positive holes on the perforating die bed die, metallic plate places on the bed die, and the mould of perforating press patrix is done the punching press action downwards, and with the metallic plate punching, a plurality of secondary holes are established in the side appropriate position in the positive hole of bed die.
