Description

Drawing die

Technical field

The utility model relates to mould applications, relates in particular to the drawing die that a kind of making automobile coaming plate that has detent mechanism is used.

Background technology

Coverings such as automobile coaming plate draw by drawing die and form, in China Patent No. is ZL200920186182.0, name is called in the patent documentation of " a kind of novel drawing die mechanism " and discloses a kind of drawing die, but because it is not provided with detent mechanism, the position of plate can not be fixed, few limit phenomenon appears in finished parts sometimes that cause producing, reprocesses and be welded to assemble to postorder to make troubles, and influences production efficiency and has strengthened labor intensity of operating personnel.

The utility model content

The utility model provide a kind of can be to being drawn the drawing die that plate positions and the position location is adjustable, solved the problem of existing drawing die because of the few limit of finished parts that lacks detent mechanism and cause.

Above technical problem solves by following technical proposal: a kind of drawing die, comprise die, punch, blank holder, the punch holder, described blank holder elasticity is connected on the described punch holder, and described blank holder is positioned at the periphery of described punch, the binder surface of described blank holder is provided with position block, and described position block is connected with described blank holder by telescoping mechanism." binder surface " is meant blank holder pressure that face by plate, size according to plate, regulate the distance of position block by telescoping mechanism apart from the outer side edges of the binder surface of blank holder, when drawing plate, plate halts after feed side enters drawing die inside and makes plate come to position block, make the finished parts that draws out can not lack the limit, if during the phenomenon of the few limit of the feed side that appearance causes because of plate diminishes in the production process, can adjust position block by telescoping mechanism, position block is reduced apart from the distance of feed side, also promptly dwindle the hem width of finished parts, increase the hem width of finished parts feed side in position block place side.

As preferably, described telescoping mechanism comprises connecting plate, and described connecting plate is provided with connecting hole, the cross section of described connecting hole is a strip, be provided with recess on the edge of described blank holder, described connecting plate is threaded in the described recess, and described position block is connected on the described connecting plate.Connecting plate is connected in the recess by the connecting hole that bolt passes on it, because of the cross section of connecting hole is a strip, so the relative position between connecting plate and the recess is adjustable, make that the position of position block on blank holder that is connected on the connecting plate is adjustable, it is convenient when adjusting to be threaded, be provided with that recess connects and the beneficial effect that connecting plate directly is not connected on the binder surface of blank holder is, if directly be connected on the binder surface, connecting plate can damage binder surface, and the binder surface that is damaged is pressed the limit that can damage finished parts by on plate the time.

As preferably, described connecting plate is connected with described recess by mount pad, and described mount pad is provided with at least two row's installing holes, and the link of described position block is provided with inverted step, and described step is arranged on the locating surface of described position block." locating surface " is meant that face that position block positions plate, mount pad is set to be connected, can make out the cross section of the recess on the binder surface of blank holder less, the binder surface area that also is blank holder reduces lessly, binder influential effect to blank holder is little, the beneficial effect that inverted step is set is, the locating surface of position block is crossed in the binder surface that recess extends blank holder, also can position when producing less plate plate, the purpose that at least two row's installing holes are set on the mount pad is, under the short situation of the connecting hole of connecting plate, can make the adjustable range of position block big.

Preferred as another, described telescoping mechanism comprises supporting seat, on described supporting seat, be provided with adjustment hole, the cross section of described adjustment hole is a strip, be equipped with threaded rod in the described adjustment hole, described position block is connected with an end of described threaded rod, at least two nuts that have been threaded on the described threaded rod, and described nut is positioned at the both sides of described supporting seat.This kind design can be by adjusting the size in the gap between the binder surface that the position of threaded rod in adjustment hole change position block and blank holder, when binder surface is on-plane surface, can guarantee that also the gap between position block and the binder surface is less, delivers to plate in this gap when preventing feeding.

As preferably, the upper end of described position block is provided with spigot surface towards a side of described punch, and described spigot surface is the inclined-plane.When plate was sent to the upper end of position block, plate can slide along spigot surface, is convenient to production operation.

The utlity model has following advantage, owing to be provided with position block, effectively avoid finished parts few limit phenomenon to occur, postorder need not to reprocess again, and the assembling of being convenient to simultaneously be welded reduces labor intensity of operating staff, enhance productivity, by telescoping mechanism is set position block and blank holder are linked together, make that the position block position is adjustable, versatility is better.
