Abstract
The utility model provides a punching head of a punching machine. The lower end surface of the punching head is provided with a concave cavity; the upper end surface of the concave cavity is smaller than the lower end surface; and the lower end surface of the punching head and the lower end surface of the concave cavity are in the same horizontal plane. The punching head of the punching machine has the beneficial effects that as the lower end surface of the punching head is concave, the punched hole is not likely to be deformed, and burrs can be effectively reduced; as the lower end surface of the punching head is provided with the concave cavity, the area of the punching head lower end surface is reduced, pressure on the material by the punching head lower end surface can be increased, hole punching on the material is easier, and burrs are fewer; and as the cutting slit is smaller, the punched hole is not likely to be deformed.
Description
Technical field
The utility model relates to perforating press field, particularly the staking punch of perforating press.
Background technology
The staking punch of present perforating press is mostly flat head, and in the time of punching, staking punch coordinates mould, under large stamping press, gets hole on material, but because staking punch is flat head, is easy to make the bore deformation that presses out, and has many burrs.
Therefore need to design a staking punch, solve this defect.
Utility model content
The utility model proposes the staking punch of perforating press, solved in prior art the yielding and more defect of burr of punching.
The technical solution of the utility model is achieved in that
The staking punch of perforating press, the lower surface of staking punch is provided with inner cavity, and the upper surface of described inner cavity is less than lower surface, and the lower surface of described staking punch and the lower surface of described inner cavity are in same level.
Further, described staking punch is provided with fixedly projection.
Further, described fixedly projection is divided into lower prop and upper cylinder by staking punch.
The beneficial effects of the utility model are: the lower surface of staking punch arranges inner cavity, reduce the area of staking punch lower surface, can increase the pressure of staking punch lower surface to material, more easily in material upper punch, portal, burr also still less, and because joint-cutting less, the hole of rushing out be not easy distortion.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
With reference to Fig. 1, the staking punch 1 of perforating press, the lower surface 5 of staking punch is provided with inner cavity 2, and the upper surface 3 of described inner cavity is less than lower surface 4, and the lower surface of described staking punch and the lower surface of described inner cavity 4 are in same level.
Further, described staking punch is provided with fixedly projection 6.
Further, described fixedly projection 6 is divided into lower prop 7 and upper cylinder 8 by staking punch.
Fixedly the effect of projection is staking punch to install on staking punch pressing plate, on staking punch pressing plate, have staking punch hole, staking punch hole is identical with staking punch lower prop size, than fixedly projection is little, under staking punch, part is by behind staking punch hole, and fixedly projection withstands on periphery, staking punch hole, and upper cylinder upper surface withstands on a stationary plane, during work, the lower surface of staking punch contacts with material, in material upper punch, portals.
The beneficial effects of the utility model are: the lower surface of staking punch arranges inner cavity, reduce the area of staking punch lower surface, can increase the pressure of staking punch lower surface to material, more easily in material upper punch, portal, burr also still less, and because joint-cutting less, the hole of rushing out be not easy distortion.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
Claims (3)
