Description
Technical field
The punching die in punching apparatus is the utility model is related to, especially a kind of adjustable punching die, particularly for
As layer insulating paper plate processing mold.
Background technology
Punching die in common punching apparatus, especially layer insulating paper plate processing mold, it is typically one kind
Core rod one set of die structure is, it is necessary to, it is necessary to which a whole set of upper die and lower die are all changed when changing upper mold core or lower mold core.It is this
It is insufficient existing for traditional structure：1st, different dimension workpieces are processed, need to use and use mould corresponding with its size, for sizes
It need to process and overpay mould, die cost is higher；2nd, need to reinstall whole set of die, the cost time is more, and production efficiency is relatively low.
Utility model content
The technical problems to be solved in the utility model is：A kind of adjustable punching die is provided, processes different dimension workpieces
Shi Wuxu dismounts whole set of die, saves the mold attaching/detaching time and saves die cost.
Technical scheme is used by the utility model solves its technical problem：A kind of adjustable punching die, including it is upper
Mould and lower mould, the lower mould include die shoe, lower mold core, lower puller bolt, lower top tight pieces, and the die shoe bottom is provided with lower mould
Groove, following side screwed hole, following side groove, the following side screwed hole communicate with following side groove, the following side groove with
Lower die cavity is communicated, and embedded lower die cavity, the lower top tight pieces are placed in the groove of following side at the top of the lower mold core, and spiral shell is held out against under described
Bolt from following side screwed hole through withstanding lower top tight pieces, stay the outer wall circular arc of core rod by the nose circle tip-cambereds of the lower top tight pieces
Face.
Further, the upper mould includes upper bolster, upper mold core, upper branch top fastening bolt, and the upper bolster bottom is provided with mould
Groove, upper lateral part screwed hole, the upper lateral part screwed hole communicate with upper die cavity, embedded upper die cavity at the top of the upper mold core, it is described on
Cylindrical at the top of core rod to offer bolt indentation, the upper branch top fastening bolt withstands upper mould through upper lateral part screwed hole to bolt indentation
Core.
The beneficial effects of the utility model are：The lower mould forms demountable structure, during for processing different dimension workpieces,
Only need to change lower mold core corresponding with its size.When changing dismounting lower mold core, lower puller bolt screws out, the nose circle of lower top tight pieces
Cambered surface depart from lower mold core outer wall arc surface, lower mold core can deviate from from lower die cavity, after replacing with new lower mold core, under hold out against spiral shell
Bolt withstands lower top tight pieces, and the nose circle cambered surface of lower top tight pieces withstands the outer wall arc surface of new lower mold core.Therefore different chis are processed
Without mould mould under dismounting entirely during very little workpiece, it is only necessary to exchange lower mold core, save the mold attaching/detaching time and save die cost.
The upper mould forms demountable structure, during for processing different dimension workpieces, it is only necessary to changes corresponding with its size
Upper mold core.When changing dismounting upper mold core, upper branch top fastening bolt screws out bolt indentation, and upper mold core can deviate from from upper die cavity, replace with
After new upper mold core, upper branch top fastening bolt screws in bolt indentation and withstands new upper mold core.Need not when therefore processing different dimension workpieces
Dismount whole upper die mold, it is only necessary to exchange upper mold core, save the mold attaching/detaching time and save die cost.
The utility model is used to that whole set of die need not to be dismounted when processing different dimension workpieces, saves mold attaching/detaching time and section
About die cost.
Brief description of the drawings
The utility model is further illustrated below in conjunction with the accompanying drawings.
Fig. 1 is the schematic cross-sectional view of lower mould in the utility model；
Fig. 2 is the schematic cross-sectional view of upper mould in the utility model；
Wherein：11st, upper bolster, 12, upper mold core, 13, upper branch top fastening bolt, 21, die shoe, 22, lower mold core, 23, under hold out against
Bolt, 24, lower top tight pieces.
Embodiment
The utility model is further described presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram only to show
Meaning mode illustrates basic structure of the present utility model, therefore it only shows the composition relevant with the utility model.
A kind of adjustable punching die, including upper die and lower die, as shown in figure 1, the lower mould includes die shoe 21, lower mould
Core 22, lower puller bolt 23, lower top tight pieces 24, it is recessed that the bottom of die shoe 21 is provided with lower die cavity, following side screwed hole, following side
Groove, the following side screwed hole are communicated with following side groove, and the following side groove communicates with lower die cavity, and the lower mold core 22 is pushed up
The lower die cavity of portion's insertion, the lower top tight pieces 24 are placed in the groove of following side, and the lower puller bolt 23 is worn from following side screwed hole
Cross and withstand lower top tight pieces 24, the nose circle tip-cambereds of the lower top tight pieces 24 is stayed the outer wall arc surface of core rod 22.
