Abstract
The utility model relates to a burr-free punching mold system, comprising a main punching mode, a back-punching mode, an upper template and a lower template, wherein the main punching mode comprises a first convex die and a first concave die; the back-punching mold comprises a second convex die and a second concave die; the first concave die is fixed on the upper template, and the second concave die is fixed on the lower template; during punching, a punched piece is firmly pressed by both the first concave die and the second concave die; the first convex die penetrates through the second concave die to complete primary punching, and then the second convex die penetrates through the first concave die to finish secondary punching. In comparison with the prior art, the burr-free punching mold system has advantages of being wide in application range, low in production cost, high in producing efficiency and the like.
Description
Technical field
The utility model relates to a kind of mould, especially relates to a kind of punching without burr mold system.
Background technology
The burr that produces in the parts machining process is a difficult problem, and processing industry solves the machined burrs problem with the cost of expensive multi-million dollar both at home and abroad.Although utilize elastic fluid to replace traditional steel punch or die to realize less than the few carrot-free processing request of 0.30mm thin plate a few days ago, thickness of slab but is difficult to reach requirement during greater than 0.30mm, even punching do not portal to come, Kong Yuexiao simultaneously, more difficult processing.Use traditional sub-punching of steel drift, because its diameter is too thin, fracture easily again, change punching pin and align and unusual trouble and consuming time.Simultaneously,, easily form bell mouth shape and tear because plastic deformation in the bottom of punching, cause the passivity burr.
Present a lot of stamping parts technique all requires without burr, and part needs to increase deburring operation after punching press, thereby has increased man-hour and the cost that rushes part.
The utility model content
The purpose of this utility model be exactly provide in order to overcome the defective that above-mentioned prior art exists a kind of scope of application wide, reduced production cost, improved the punching without burr mold system of production efficiency.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of punching without burr mold system, it is characterized in that, comprise main stamping die, recoil mould, cope match-plate pattern and lower bolster, described main stamping die comprises the first punch and the first die, described recoil mould comprises the second punch and the second die, described the first die is fixed on the cope match-plate pattern, described the second die is fixed on the lower bolster, during punching press, described the first die and the second die compress the part that is stamped, described the first punch passes the second die do for the first time punching press after, described the second punch passes the first die and does for the second time punching press.
Described cope match-plate pattern is connected with lower bolster by guide pillar.
Described cope match-plate pattern is provided with the first fairlead for the first punch guiding.
Described lower bolster is provided with the second fairlead for the second punch guiding.
Compared with prior art, the utlity model has following advantage:
1, the scope of application is wide, and common punch press all can use;
2, reduce production cost, improved production efficiency, saved following process;
3, improved Product Precision.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of punching without burr mold system, comprise main stamping die, the recoil mould, cope match-plate pattern 3 and lower bolster 4, described main stamping die comprises the first punch 8 and the first die 2, described recoil mould comprises the second punch 9 and the second die 1, described the first die 8 is fixed on the cope match-plate pattern 3, described the second die 1 is fixed on the lower bolster 4, during punching press, described the first die 2 and the second die 1 compress the part that is stamped, described the first punch 8 passes the second die 1 do for the first time punching press after, described the second punch 9 passes the first die 2 and does for the second time punching press.
Described cope match-plate pattern 3 is connected with lower bolster 4 by guide pillar 5.Described cope match-plate pattern 3 is provided with the first fairlead 6 for the first punch guiding.Described lower bolster 4 is provided with the second fairlead 7 for the second punch 9 guiding.
Operation principle is as follows:
During punching press, the first die 2 and the second die 1 first subtend compress the part that is stamped, then the first punch 8 of main stamping die pass the recoil mould the second die 1 endoporus do incomplete punching press, when the first punch 8 homing of main stamping die, the second punch 9 of recoil mould passes the first die 2 endoporus of main stamping die same punching position is oppositely made complete stamping-out.After the second punch 9 homings of recoil mould, the first die 2 and the second die 1 unclamp the part that is stamped.
Claims (4)
1. punching without burr mold system, it is characterized in that, comprise main stamping die, recoil mould, cope match-plate pattern and lower bolster, described main stamping die comprises the first punch and the first die, described recoil mould comprises the second punch and the second die, described the first die is fixed on the cope match-plate pattern, described the second die is fixed on the lower bolster, during punching press, described the first die and the second die compress the part that is stamped, described the first punch passes the second die do for the first time punching press after, described the second punch passes the first die and does for the second time punching press.
