Abstract
The invention discloses a non-burr punching die. The die comprises an upper die, a lower die, a blanking hole and mounting positions, wherein the lower die is provided with the blanking hole; the upper die and the lower die are provided with the mounting positions; and the fit clearance between the upper die and the lower die is small. By adopting the mode, the die has the advantages that the reliability is high, the structure is simple, no burrs are produced in punched finished products, and the like, and has a wide market prospect in the field of machine manufacturing.
Description
Technical field
The present invention relates to mould applications, particularly relate to a kind of without the burr diel.
Background technology
Forcing press is depended in punching press and mould applies external force to sheet material, band, tubing and section bar etc., make it to produce plastic deformation or separation, thereby obtain the forming and machining method of the workpiece of required form and size, because its production efficiency is high, the workpiece size precision is high, machinable size range is large, and cost is low, extensive use in industrial production, but due to technical limitations such as moulds, cause punching parts burr to occur, often need again to process, remove burr.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of without the burr diel, prevent that by the mode of adjusting mould fit clearance and raising mold and punching head surface smoothness the punching press burr from producing, have that reliability is high, simple in structure, presswork is without advantages such as burr, in mechanical manufacturing field, market prospects widely arranged.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of without the burr diel, comprising: mold, bed die, material-dropping hole and installation position, and bed die offers material-dropping hole, mold is provided with drift, and mold and lower grinding tool offer installation position.
In a preferred embodiment of the present invention, the fit clearance of described mould is little.
In a preferred embodiment of the present invention, described mold punch edge is carried out electroplating processes and is improved surface smoothness.
The invention has the beneficial effects as follows: the present invention prevents that by the mode of adjusting mould fit clearance and raising mold and punching head surface smoothness the punching press burr from producing without the burr diel, have that reliability is high, simple in structure, presswork is without advantages such as burr, in mechanical manufacturing field, market prospects widely arranged.
Description of drawings
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, in below describing embodiment, the accompanying drawing of required use is briefly described, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings, wherein:
Fig. 1 is the structural representation without burr diel one preferred embodiment of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, bed die, 2, mold, 3, drift, 4, the blanking hole body, 5, installation position.
The specific embodiment
Below will the technical scheme in the embodiment of the present invention be clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Based on the embodiment in the present invention, those of ordinary skills, not making all other embodiment that obtain under the creative work prerequisite, belong to the scope of protection of the invention.
See also Fig. 1, the embodiment of the present invention comprises:
A kind of without the burr diel, comprising: mold 2, bed die 1, material-dropping hole 4 and installation position 5, bed die 1 offers material-dropping hole 4, and mold 2 is provided with drift 3, and mold 2 and bed die 1 offer installation position 5.
The fit clearance of described mould is little, prevents the generation of punching burr.
Described mold 2 punch edge are carried out electroplating processes and are improved surface smoothness, prevent the generation of punching burr.
The present invention without the beneficial effect of burr diel is:
One,, by adjusting fit clearance and drift being carried out best bright finish process, make mould when punching press, avoided the generation of punching burr;
Two, the present invention without the burr diel have that reliability is high, simple in structure, presswork is without advantages such as burr, in mechanical manufacturing field, market prospects widely arranged.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or equivalent flow process conversion that utilizes description of the present invention to do; or directly or indirectly be used in other relevant technical field, all in like manner be included in scope of patent protection of the present invention.
