Abstract

The invention discloses a closed trimming die, which comprises an upper die holder and a lower die holder. The closed trimming die is characterized in that a slidable support seat is further arranged on the lower die holder, the support seat and a cavity in a punch form a closed trimming cavity when the support seat is in a working condition state, and a top plane of the support seat is higher than a plane of a notching groove when the support seat is not in operation, and is gradually lower than the plane of the notching groove when the closed trimming die is used for cutting. A forged part is precisely positioned in the support seat of a lower die, the support seat is in clearance slide fit with a cutting edge of the lower die, an upper die downwards moves until the forged part is attached to the support seat of the lower die to form a closed cavity, and at the moment, the forged part continues moving downwards in the closed cavity until trimming operation is completed. Accordingly, the forged part is trimmed in a precisely positioned closed space, deformation and burrs of the forged part are completely avoided.

Description

A kind of enclosed shaving die
Technical field
Involved in the present invention is a kind of improvement invention that is applied to forge the side cut processing mold when producing.
Background technology
In the prior art, common forging shaving die is that open type is cut edge.Can produce following shortcoming: 1, because in the side cut process, the side cut counterdie does not support and compresses forging, forging makes its buckling deformation in the moment of cutting edge owing to shear the tension that produces, and has a strong impact on the product precision.2, because common edger product only relies on counterdie working face location, and positioning accuracy reduces along with the wearing and tearing of working face, causing cutting edge produces burr, thereby increases the polishing operation, increases cost.
Summary of the invention
Given this, the technical problem that the present invention solved provides a kind of compact conformation, and the technical problem that the present invention will solve is to be to provide the mould that can avoid forging to produce forging side cut distortion and burr.In order to realize above-mentioned technical purpose; The present invention adopts following technical scheme to realize: this kind enclosed shaving die, include upper bolster and die shoe, and said upper bolster is provided with drift; Be provided with the shape chamber that is complementary with the workpiece shape in the said drift; Said die shoe is provided with the die head of band cutting edge, also is provided with the groove of blurting out on the said die head, and said cutting edge is arranged on the edge of the groove of blurting out; It is characterized in that also being provided with on the said die shoe slidably supporting seat; Said supporting seat under work condition state with drift in the shape chamber constitute a closed side cut chamber, and said supporting seat when not working its top plan be higher than the groove plane of blurting out, its plane is lower than the groove plane of blurting out gradually when cutting.
The bottom of said supporting seat is provided with alignment pin, and said alignment pin bottom is provided with flexible member.
Forging of the present invention accurately is positioned in the counterdie supporting base, and supporting base is snug fit in the counterdie cutting edge with the 0.02-0.03 mm clearance again.Forging is before accomplishing the action of cutting edge, and at first patrix moves down, up to the die cavity that compresses a sealing of the sturdy formation of forging and counterdie supporting base.This moment, forging continued to move downward at the die cavity of sealing, accomplished up to the featherer.The side cut processing that has so just formed forging is carried out in pinpoint enclosure space, has avoided the generation of forging distortion and the generation of burr fully.
Doubly, the present invention compared with prior art has substantive distinguishing features and progress.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is a structure side view of the present invention;
Fig. 3 is a structure vertical view of the present invention;
Structural representation when Fig. 4 prepares for work of the present invention;
Structural representation when Fig. 5 moves downward for patrix of the present invention;
Fig. 6 moves downward structural representation when being adjacent to workpiece for patrix of the present invention;
Fig. 7 carries out the structural representation of slitter edge excision for the common workpiece pressing of upper and lower mould of the present invention continues to move downward.
The specific embodiment
Accompanying drawing has been represented structure of the present invention and embodiment, combines accompanying drawing further to set forth the relevant details and the operation principle of embodiment below again.This kind enclosed shaving die includes upper bolster 1 and die shoe 2, and said upper bolster is provided with drift 3; Be provided with the shape chamber 7 that is complementary with the workpiece shape in the said drift, said die shoe 2 is provided with the die head of band cutting edge, also is provided with the groove (not shown) of blurting out on the said die head; Said cutting edge is arranged on the edge of the groove of blurting out, and it is characterized in that also being provided with on the said die shoe slidably supporting seat 6, said supporting seat 6 under work condition state with drift in shape chamber 7 when constituting closed side cut chambeies and said supporting seat 6 and not working its top plan be higher than the groove plane of blurting out; Its plane is lower than the groove plane of blurting out gradually when cutting; The bottom of said supporting seat 6 is provided with alignment pin 9, and said alignment pin bottom is provided with flexible member, and this flexible member is a spring 8; Spring housing is on alignment pin 9; Behind die-cut the finishing, its spring can be reset to original state again with supporting seat, carries out die-cut next time.
Forging of the present invention accurately is positioned in the counterdie supporting base, and supporting base is snug fit in the counterdie cutting edge with the 0.02-0.03 mm clearance again.Forging is before the action of accomplish cutting edge, and at first patrix moves down, up to the die cavity of patrix with a workpiece and a sealing of the sturdy formation of counterdie supporting base; Because the spring on the counterdie supporting seat can withstand with workpiece supporting seat on patrix, therefore the shape chamber of sealing has been configured like this, and this moment, workpiece continued to move downward with supporting seat at the die cavity of sealing; When moving to the blurting out during groove cutting edge place of counterdie; Drift on the patrix continues to move downward, and when the periphery of workpiece contacted the cutting edge place, the pressure of drift can be cut edge to workpiece; And because in the side cut process; Supporting seat moves with workpiece always, and the spring of supporting seat bottom has a power that makes progress asking workpiece carrying out the slitter edge excision always, accomplishes up to the featherer; The side cut processing that has so just formed forging is carried out in pinpoint enclosure space, has avoided the generation of forging distortion and the generation of burr fully.The present invention compared with prior art has substantive distinguishing features and progress.
