Description
Technical field
The utility model relates to a kind of heat sink bending die.
Background technology
Similar enclosed shutter, open type shutter, Dan Qiao, doube bridge etc. in sheet metal component is belonged to the body of shallow stretching, if production type belongs to jobbing work, usually can adopt NC turret punch machine to be shaped, mould-type is of all kinds, such as: single hole mould, porous mold, shutter mould and bridge type mould etc.Wherein, louver tool and bridge type mould belong to die-cut and add stretch forming class mould.For the type mould, light spring assembly will be appropriately selected to carry out binder during punching press, to prevent the distortion of plate, to tear and distortion, or unevenly cause unloading difficulties etc. because being out of shape, product requires air vent shaping rear surface flat smooth, without phenomenons such as button song, crackings, it can thus be appreciated that this product air vent bending forming is the difficult point of this product punching press.
Utility model content
The main object of the utility model is, overcomes the deficiencies in the prior art, proposes a kind of heat sink bending die.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of heat sink bending die, comprise cushion block, die shoe, guide pillar, limited block, spring, guide pin bushing, upper bolster, die shank, bending punch, unloading bolt, upper padding plate, punch retainer, holding pad, concave template, lower bolster, locating pin and retainer plate, cushion block connects die shoe, guide pillar connects die shoe and upper bolster respectively, limited block connects bending punch, spring connects unloading bolt, guide pin bushing is enclosed within guide pillar top, upper bolster connects die shank, bending punch connects upper padding plate, unloading bolt connects upper bolster and holding pad respectively, upper padding plate connects punch retainer, holding pad connects concave template, concave template connects lower bolster, lower bolster connects die shoe, locating pin nail is on retainer plate, retainer plate connects die shank.
Have employed technique scheme, the beneficial effects of the utility model are:
Rational in infrastructure, reliable, easy to use, the product of production is qualified, makes heat sink product venting section direct bending forming, the phenomenon such as air vent shaping rear surface flat smooth, distortionless, cracking.
Accompanying drawing explanation
Fig. 1 is forward sight structural representation of the present utility model.
Fig. 2 is plan structure schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As Fig. 1, shown in Fig. 2, a kind of heat sink bending die, comprise cushion block 1, die shoe 2, guide pillar 3, limited block 4, spring 5, guide pin bushing 6, upper bolster 7, die shank 8, bending punch 9, unloading bolt 10, upper padding plate 11, punch retainer 12, holding pad 13, concave template 14, lower bolster 15, locating pin 16 and retainer plate 17, cushion block 1 connects die shoe 2, guide pillar 3 connects die shoe 2 and upper bolster 7 respectively, limited block 4 connects bending punch 9, spring 5 connects unloading bolt 10, guide pin bushing 6 is enclosed within guide pillar 3 top, upper bolster 7 connects die shank 8, bending punch 9 connects upper padding plate 11, unloading bolt 10 connects upper bolster 7 and holding pad 13 respectively, upper padding plate 11 connects punch retainer 12, holding pad 13 connects concave template 14, concave template 14 connects lower bolster 15, lower bolster 15 connects die shoe 2, locating pin 16 is followed closely on retainer plate 17, retainer plate 17 connects die shank 8.
Wherein, limited block has 3.
Bending die is also provided with limited post 18, and the bottom surface of bending punch is contacted with limited block.
Heat sink product relies on location-plate and locating pin location, before bending forming by holding pad to after product binder, patrix is descending, and bending punch is to venting section bending forming, and patrix is up, and holding pad relies on spring force to be unloaded from bending punch by product.
