Abstract
The utility model relates to a progressive die with an internal chamfer, which comprises an upper die and a lower die. The upper die consists of an upper die plate and an upper fixing plate fixed to the lower side of the upper die plate, a discharge plate is arranged on the lower side of the upper fixing plate, the lower die comprises a lower die plate and a female die fixing plate fixed onto the lower die plate, corresponding upper and lower correcting dies, corresponding upper and lower notching dies, corresponding upper and lower chamfering dies, corresponding upper and lower re-notching dies, corresponding upper and lower forming dies, corresponding upper and lower rounding dies, corresponding upper and lower shaping dies, corresponding upper and lower discharge dies and corresponding upper and lower cutting dies are sequentially fixed from a feeding position to a discharging position, and upper and lower raising dies are respectively disposed among the upper and lower notching dies and the upper and lower chamfering dies and among the upper and lower chamfering dies and the upper and lower re-notching dies. The upper and lower raising dies are added to fronts and rears of the upper and lower chamfering dies, accordingly, middle strips move upwards, unevenness at cut positions after the strips are discharged is avoided, and the quality of products and production efficiency are improved. In addition, by the aid of the progressive die, connecting materials between two workpieces do not need to be widened, and materials cannot be wasted.
Description
Technical field
The utility model relates to the moulds of industrial equipment of friction feeding, specifically a kind of interior chamfering progressive die of mould that is used to roll up round part.
Background technology
At present, the progressive die that is used for the punching out workpiece has been widely used in mechanical manufacturing field, and to fall the progressive die at big angle few but be used to roll up round part complete cycle.Like Fig. 3, product shown in Figure 4, because this product annual production is big, if adopt single mode to make not only cost of idleness but also be difficult to guarantee output; Therefore need to adopt the progressive die and want friction feeding, but there is big chamfering at this product two, material is walked about in middle strip after the chamfering; Because this product is produced with the progressive die, material send in mould continuously, and material will move in middle strip continuously after the chamfering; Like this to last once the step during blanking cut-off part have length; Uneven before and after occurring, cause product defective, such workpiece is not satisfy customer requirement.
Just must stop material to move forward if produce qualified product.Proper a solution is that the company material place in the middle of two workpiece dashes a mounting hole, and material unnecessary when letting chamfering is extruded in the mounting hole.If adopt this method, the company's material between two workpiece must be wide, so will waste material, and cost has just improved.
Summary of the invention
The utility model provides the chamfering progressive die in a kind of mould to the problems referred to above, and material moved in middle strip after this progressive die can stop chamfering, and can waste material.
Technical scheme according to the utility model: the chamfering progressive die in a kind of mould, comprise patrix and counterdie, said patrix comprises cope match-plate pattern and is fixed on the upper mounted plate under the said cope match-plate pattern that the below of said upper mounted plate is provided with stripper; Said counterdie comprises lower bolster and is fixed on the die block on the said lower bolster; Said upper mounted plate reaches on the said die block down; Be fixed with corresponding correcting, jet-bedding, chamfering, jet-bedding, shaping, volume circle, shaping, blanking and cut off upper and lower mould more successively from charging place to discharging place, be provided with the raising upper and lower mould between said jet-bedding upper and lower mould and the said chamfering upper and lower mould and between said chamfering upper and lower mould and the said upper and lower mould of jet-bedding again.
Said raising upper and lower mould comprises the raising punch that is fixed on the said die block and is arranged on the raising groove on the said stripper.Be provided with upper padding plate between said upper mounted plate and the said cope match-plate pattern.Be provided with lower bolster between said die block and the said lower bolster.Said lower bolster is fixed on the base plate through the pad pin.
The technique effect of the utility model is: the utility model has increased the raising upper and lower mould in the front and back of chamfering upper and lower mould; The material of strip is up walked in the middle of making; Material just can not move forward in middle strip like this; Cut-off part does not just have uneven phenomenon behind the blanking, has improved the quality of product, has improved production efficiency; The utility model need not widened two company's material between the workpiece, can waste material.

The specific embodiment
Be further described below in conjunction with the specific embodiment of accompanying drawing the utility model.
Among Fig. 1, Fig. 2, comprise base plate 1, pad pin 2, lower bolster 3, lower bolster 4, die block 5, stripper 6, upper mounted plate 7, upper padding plate 8, cope match-plate pattern 9, correcting hole drift 10, raising punch 11, chamfering punch 12, crooked die 13, shaping die 14, last correcting die 15, blanking punch 16, waste material cutter 17, cut waste material die 18, blanking die 19, following correcting die 20, plug 21, crooked punch 22 etc.
Like Fig. 1, shown in Figure 2, the utility model is the chamfering progressive die in a kind of mould, comprises patrix and counterdie.
Patrix comprises cope match-plate pattern 9 and is fixed on the upper mounted plate 7 under the cope match-plate pattern 9, has been provided with the upper padding plate 8 of corrective action between upper mounted plate 7 and the cope match-plate pattern 9.The below of upper mounted plate 7 is provided with stripper 6.
Counterdie comprises lower bolster 3 and is fixed on the die block 5 on the lower bolster 3, has been provided with the lower bolster 4 of corrective action between die block 5 and the lower bolster 3.Lower bolster 3 is fixed on the base plate 1 through pad pin 2.
On the die block 5 of the upper mounted plate 7 times of patrix and counterdie, be fixed with corresponding correcting, jet-bedding, chamfering, jet-bedding, shaping, volume circle, shaping, blanking and cut off upper and lower mould more successively from charging place to discharging place.Above-mentioned upper and lower mould comprises correcting hole drift 10 and counterdie, jet-bedding drift and counterdie, chamfering punch 12 and counterdie, crooked die 13 and crooked punch 22, shaping die 14 and plug 21, last correcting die 15 and following correcting die 20, blanking punch 16 and blanking die 19, waste material cutter 17 and cuts waste material die 18.
