Abstract
The utility model relates to a fine blanking die which comprises a male die fixed plate, a male die, a base plate, an upper die plate, a die shank, a stripper plate, a blanking female die and a trimming female die and is characterized in that the die shank and the upper die plate are positioned at the upper end of an upper die; the die shank is pressed into the upper die plate from the bottom of the upper die plate. The fine blanking die has a simple structure, is easy to manufacture and is convenient to operate.
Description
Technical field:
The utility model relates to a kind of fine-blanking die, particularly a kind of fine-blanking die of extra die.
Background technology:
Fine-edge blanking technology is a frontier of stamping technology development, is one of advanced process.Its appearance, has fundamentally changed the technology chain that metal blank is processed.Essence punching is not only a kind of part and is all replaced the method for casting, forging, powder metallurgy and process for machining, and is the processing technology of a kind of high-quality, high efficiency and high added value.
Fine-edge blanking technology be from the twenties in 20th century since Europe invention, experienced the course of more than 80 year, be to be that slab is manufactured one of most important precision plastic forming mode in field.Fine-edge blanking belongs to ELEMENTARY INTRODUCTION TO NON technology, is a kind of fine blanking method growing up on common stamping technology basis, is called for short essence punching.It can obtain the high-quality fine blanking part higher than common stamping parts size precision, the bright and clean warpage of stamping-out face is little and interchangeability is good in a punching stroke, and reaches the improvement of product quality with lower cost.Conventional fine blanking method has little gap fillet stamping-out, fillet stamping-out, reciprocal stamping-out, blanking with opposed dies at present.Only have common punch press at some working conditions, the mould also simple and crude small enterprise that creates conditions, if adopt fine-edge blanking technique, must design the fine blanking die that gear ring pressure and push pedal counter-pressure can be provided, its mould structure complexity, and cost is higher.
Summary of the invention:
The purpose of this utility model is to provide a kind of fine-blanking die mechanism of extra die, and described this mold mechanism will solve every cover fine blanking die will provide the problem of gear ring pressure and push pedal counter-pressure.
The utility model can perfectly solve the above-mentioned problem that gear ring pressure and push pedal counter-pressure need to be provided, and makes mould structure simple, and cost is lower, and the scope of application is more extensive.
The purpose of this utility model is achieved through the following technical solutions: improve common stamping mould structure, design is easy to manufacture, also can on common punch press, realizes the Simple Fine Blanking tool of fine-edge blanking.
Improve mould structure, below punching and blanking die, add a deburring die, be specifically designed to the refine of stamping-out section.And assist and improve stamping stress, receive good result.Simple Fine Blanking lamps structure is shown in Fig. 1.
Operation principle of the present utility model is: when work, billot is sent to, elastic stripper with boss compresses billot, after stamping-out, product is that die and extra die are spilt by lower material spilling hole by two-layer die in turn, and the smear metal that extra die refine is got off is discharged automatically through middle chip area.Specially consider and be subject to stronger friction, wearing and tearing and tension effect to die, for improving die life, structurally adopt edge spelling mode, and apply outer ring hot cover process, with realize appropriateness radially compressive pre-stress is offset some work time the suffered tension that structurally adopts edge spelling mode.
The utility model adopts above-mentioned Simple Fine Blanking tool to realize fine-edge blanking, is feasible through production practices checking.The utility model is compared with prior art, and its effect is actively with obvious.Compared with the punch die with gear ring pressing plate of routine, that this mould has is simple in structure, easy to manufacture, easy to operate, use safety, productivity ratio is higher, to advantages such as pressing equipment requirement are low.Especially in the situation that not having essence to rush equipment,, processability of product structure good product not too complicated for contour shape, transport and have in this way good techno-economic effect.Product is smooth, and section surface roughness reaches Ra0.8um, without shear fracture band, substantially without burr.In product plane, occur without obvious plastic compression band along stamping-out edge, dimensional accuracy meets the requirements.
Brief description of the drawings: this mould have simple in structure, easy to manufacture, easy to operate, use safety, productivity ratio higher, to advantages such as pressing equipment requirement are low.Especially in the situation that not having essence to rush equipment,, processability of product structure good product not too complicated for contour shape, transport and have in this way good techno-economic effect.Product is smooth, and section surface roughness reaches Ra0.8um, without shear fracture band, substantially without burr.In product plane, occur without obvious plastic compression band along stamping-out edge, dimensional accuracy meets production requirement.
Accompanying drawing is the utility model structure diagram.
Detailed description of the invention:
As shown in the figure, punch 4 is fixed by punch retainer 8, and mode with bolts is connected with die shank 1 backing plate 2 and punch retainer 8, and binder, stripper 5 are to be also connected with backing plate 2 and punch retainer 8 with unloading bolt 9.Below Dies ' Blanking die 6, adopt edge spelling mode to add a deburring die 7.
When specific works, billot or band material are sent to, elastic stripper 5 with boss compresses billot or band material, and after stamping-out, product is that die 6 and extra die 7 are spilt by lower material spilling hole by two-layer die in turn, and the smear metal that extra die 7 refine are got off is discharged automatically through middle chip area.
