The invention provides a punching mold, which comprises an upper mold and a lower mold, wherein the upper mold is sequentially connected with an upper support plate, an upper pad block, an upper mold seat, an upper pad plate, an upper clamp plate and an upper releasing plate; the lower mold is sequentially connected with a lower support plate, a lower pad block, a lower mold seat, a lower pad plate and a lower template from bottom to top; a plurality of flanging mechanisms, a plurality of convex point making mechanisms and a plurality of hole punching mechanisms are respectively arranged between the upper mold and the lower mold; an upper positioning block is arranged on the upper mold seat; a lower positioning block is arranged on the lower mold seat; the upper positioning block is matched with the lower positioning block. The punching structure is reasonable; the operation is convenient; the work procedures such as flanging, convex point making, hole punching and shaping on a workpiece can be completed at the same time; meanwhile, the precision requirements of the workpiece are ensured; the production flow process is simplified; the production efficiency of the punched workpiece is greatly improved; the production cost is reduced; the process requirement of a customer on the workpiece is met.

Description

A kind of diel

Technical field

The present invention relates to technical field of mold, be specifically related to a kind of diel.

Background technology

Along with improving constantly of industrial product quality, mould product generates the kind that presents, fewIn batches, complicated, large-scale precision update speed is fast. Design of Dies and technology are due to craftEquipment, relies on artificial experience and conventional machined, and technology, to CAD, is countedControl-register journey smear metal processing, the Computer-aided Design Technology of numerical control electric machining core changes. MouldTool is produced the high accuracy that product shows, high complexity, high production rate, high uniformityThat other manufacture processing aspect can not fully display with offsetting consumption, thus the warp having hadJi benefit is therefore used widely in batch production, in existing chemical industry is produced, has tenDividing consequence, is requisite processing method in China's national defense industry and civilian production.

Diel is the requisite technological equipment of punching production, is technology-intensive product.Quality, production efficiency and the production cost etc. of stamping parts, have directly with Design of Dies and manufactureConnect relation. The height of Design of Dies and manufacturing technology level is to weigh a national product systemMake one of important symbol of level height, determining to a great extent quality, the effect of productThe development ability of benefit and new product.

And in many production workpiece of modern times, multiple working procedure need to complete simultaneously. Because workpieceIf the single process operations of workpiece that makes of complexity, caused increasing the difficulty of next procedure,Can, because of the precision of the operating influence last process of this procedure, seriously can cause appearance simultaneouslyThe defects such as face is wrinkling, damaged surfaces, percent defective is high, cannot obtain higher surface quality,And increased production cost, and reduce production efficiency, can not ensure the high accuracy of workpiece.

Therefore, the present invention proposes to complete the diel of multiple working procedure.

Summary of the invention

The object of this invention is to provide a kind of rational in infrastructure, can complete to workpiece take out tooth, punching,The diel of raising.

The present invention is achieved through the following technical solutions:

A kind of diel, comprises upper die and lower die, and described patrix connects from top to bottom successivelyThere are mounting plate, upper cushion block, upper bolster, upper padding plate, train wheel bridge and upper de-plate, described counterdieBe connected with from bottom to top bottom plate, lower cushion block, die shoe, lower bolster and lower bolster in turn,Between described upper die and lower die, be respectively equipped with several Chou Ya mechanisms, several raising point mechanismsWith several punch mechanisms, described upper bolster is provided with locating piece, on described die shoe, establishesHave lower locating piece, described upper locating piece and lower locating piece match.

Further, Chou Ya mechanism comprises takes out tooth punching, g top and spring a, takes out the fixing peace of tooth punchingBe contained on upper bolster, spring a is fixedly mounted on die shoe, and spring a upper end is connected withG top.

Further, raising point mechanism comprises raising punching, jigger pin and spring b, raising punchingBe fixedly mounted on upper bolster, spring b is fixedly mounted on die shoe, and spring b upper end connectsBe connected to jigger pin.

Further, punch mechanism comprises drift and lining, at the bottom of described drift is arranged on upper bolsterEnd, lining is positioned on lower bolster.

Further, described upper bolster bottom is provided with auxiliary guide pillar.

Further, described upper bolster is provided with inner guiding post, interior guide pin bushing on die shoe, described inInner guiding post and interior guide pin bushing match.

The invention has the beneficial effects as follows: this punching structure is reasonable, easy to operate, can be simultaneously completeIn pairs workpiece take out the operations such as tooth, raising point, punching, shaping, ensured workpiece simultaneouslyRequired precision, has simplified production procedure, greatly improves the production efficiency of stamped workpieces, reducesProduction cost, meets the technological requirement of client to workpiece.
