Description
Technical field
The utility model is related to rapid forming mold technical fields, more specifically, it relates to be sent in a kind of double-station die
Expect mechanism.
Background technology
In trial production of new products and small lot production stamping parts, simple punching die structure is generally used.This punch die is not
It is only simple in structure, but also have the characteristics that workpiece punch die easily manufactured, of low cost, and can meeting certain.Currently, one
As stamping parts all can not one-pass molding, it is necessary to by a stamping parts Multi-step forming, for the press work of aspect stamping parts, one
As two stamping dies are merged into a single whole, and feed device is set inside.In punching production, feed mode mainly uses gas
Dynamic feeder is pushed, and it is big that disadvantage mainly embodies a concentrated reflection of workpiece step pitch, cannot accurately control；It is uncertain due to pneumatically having
Property, therefore causing feeding inaccurate, feeding is unstable.
The Chinese patent of Publication No. CN203418030U discloses feed device in a kind of mould, including slotting tool, fixed block,
Floating feed block, sliding block, sliding block cushion block and power transmission pin, the slotting tool upper end are fixed on cope plate, and lower end has an inclined-plane, institute
The floating feed block upper end inclined-planes Ye Youyi are stated, are matched with the inclined-plane of slotting tool, fixed block is arranged in floating feed block lower end；Institute
The side for stating the non-inclined-plane in slotting tool lower end is provided with power transmission pin, and positioning pin is installed right over power transmission pin, and positioning pin is determined in workpiece bottom
Position workpiece to be punched；Above the floating feed block, floating feed pin is installed in the decentralization of workpiece to be punched；In floating feed block
Power transmission spring is installed between fixed block, floating feed block lower part is additionally provided with sliding block cushion block.
When slotting tool moves downward, floating feed block is squeezed, floating feed pin is driven to move a station, it is floating to drive
Workpiece movement in dynamic feeding pin, drives the waiting of floating feed block homing to send next time after feeding by power transmission spring
Expect work；But according to intrinsic specification and Figure of description it is found that stamping parts mainly by floating feed block into
Row push, therefore the push distance of stamping parts is limiting for width by floating feed block and slotting tool and contact area, and by
The bigger that the limitation of press machine model, slotting tool and floating feed block can not be arranged so that the push distance of stamping parts extremely has
It limits and is difficult to increase.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide feeders in a kind of double-station die
Structure, have the advantages that improve stamping parts push apart from.
To achieve the above object, the utility model provides following technical solution：
Feed mechanism in a kind of double-station die, including upper die holder and lower die holder, the upper die holder lower end are fixedly connected with
Upper stamping die, the lower die holder upper end are fixedly connected with lower stamping die, on the lower die holder setting there are two processing stand, it is described on
The supporting rod that die holder lower end is also fixedly connected, trapezoidal shape setting is provided on the supporting rod side wall and inclined surface is set up
The first wedged block, be provided with workbench on the lower die holder, the supporting rod is arranged in workbench, is slid on the workbench
