Description
Technical field
The present invention relates to a kind of diel of the punching press flanging bore on sheet metal component inclined-plane.
Background technology
The common diel of punching press flanging bore on sheet metal component inclined-plane, as shown in figure 1, on the upper holding pad of upper bolster
Provided with sliding inclined wedge, upper bolster is provided with the drive block of driving sliding inclined wedge, and drift, the buoyance lift of die shoe are set on sliding inclined wedge
Plunging die button is movably equipped with seat, because drift is arranged on sliding inclined wedge, and sliding inclined wedge is arranged on the upper holding pad of activity
Go up and lean on drive block to drive, and plunging die button is movably arranged on the buoyance lift seat of up and down motion, between drift and plunging die button
Kinematic error is big, causes punching precision to be difficult to reach very high request；And due to upper holding pad and plunging die button be it is up and down,
After long-time use, more large deviation just occurs in die wear, hole flanging precision.
The content of the invention
The technical problems to be solved by the invention are：There is provided a kind of machining accuracy the high punching press flange on sheet metal component inclined-plane
The diel in hole.
In order to solve the above technical problems, the technical solution adopted in the present invention is：One kind punching press on sheet metal component inclined-plane is turned over
Lateral opening diel, including upper bolster and die shoe, are fixed with drift on upper bolster, die shoe be provided with it is stair-stepping into
Type hole, forming blocks are provided with die shoe in forming hole, and forming blocks include base and the tube being arranged on base, tubulose
Back-moving spring is arranged with portion, back-moving spring is fastened on the cascaded surface of base and forming hole, and pusher bullet is embedded with tube
Spring, sliding block installation cavity is provided with die shoe below forming blocks, the cunning that driving forming blocks are moved upwards is provided with sliding block installation cavity
Block, side is provided with the material returned inclined-plane being engaged with forming blocks bottom surface on sliding block, and opposite side is provided with driving inclined-plane, upper bolster on sliding block
Driving sliding block is provided with to be provided with close to slider-actuated inclined-plane side in the driving wedge for being molded Block direction movement, die shoe
The driving chamber being engaged with driving wedge, it is provided with side of the sliding block away from driving wedge in die shoe and promotes sliding block to close to driving
The horizontal spring of dynamic wedge direction motion.
As a kind of preferable scheme, the driving wedge is spacing scarce provided with what is be engaged with sliding block close to sliding block side
Mouthful.
As a kind of preferable scheme, the middle part of the drift is provided with annular groove, and the section of annular groove is in circular arc.
The beneficial effects of the invention are as follows：Because drift is directly fixedly installed on upper bolster, forming blocks are arranged on die shoe
In, and the slider-actuated by being arranged in die shoe so that the kinematic error between drift and forming blocks reduces, so as to improve punching
Hole precision.
Because die shoe is provided with stair-stepping forming hole, forming blocks are provided with die shoe in forming hole, in die shoe
It is provided with sliding block installation cavity below forming blocks, is provided with the sliding block that driving forming blocks are moved upwards in sliding block installation cavity, one on sliding block
Side is provided with the material returned inclined-plane being engaged with forming blocks bottom surface, and opposite side is provided with driving inclined-plane on sliding block, and upper bolster is provided with driving
Sliding block is to close to the driving wedge for being molded Block direction movement so that punching precision is more easy to ensure, and this structure causes some portion
Part occurs readily replaceable after wearing.
Because forming blocks include base and the tube being arranged on base, back-moving spring is arranged with tube, it is multiple
Position spring is fastened on the cascaded surface of base and forming hole, and after sliding block is removed, forming blocks are in the presence of back-moving spring to moving down
It is dynamic so that tube disengages a segment distance with flanging bore hole wall so that feeding is more easy.
Due to being embedded with pusher spring in tube, machine rear pusher spring and promote material to depart from forming blocks so that
Material is more easy to be removed.
Due to the driving wedge close to sliding block side provided with the spacing breach being engaged with sliding block so that sliding block is in punching
During be not in rock, further ensure that machining accuracy.
Because the middle part of drift is provided with annular groove, the section of annular groove is in circular arc, is easy to drift good from punching press
Taken off in workpiece, without deforming upon piercing and flanging portion.

Embodiment
Below in conjunction with the accompanying drawings, specific embodiments of the present invention are described in detail.
As Figure 1-3, a kind of diel of the punching press flanging bore on sheet metal component inclined-plane, including upper bolster 1 and lower mould
Seat 2.Drift 3 is fixed with upper bolster 1, the middle part of drift 3 is provided with annular groove, and the section of annular groove is in circular arc.Under
Die holder 2 is provided with stair-stepping forming hole, and forming blocks 4 are provided with forming hole in die shoe 2.Forming blocks 4 include base and
The tube being arranged on base, back-moving spring 5 is arranged with tube, back-moving spring 5 is fastened on the rank of base and forming hole
Pusher spring 6 is embedded with tread, in tube.
Be provided with the installation cavity of sliding block 7 in die shoe 2 below forming blocks 4, be provided with the installation cavity of sliding block 7 driving forming blocks 4 to
The sliding block 7 of upper motion, side is provided with the material returned inclined-plane being engaged with the bottom surface of forming blocks 4 on sliding block 7, and opposite side is provided with sliding block 7
Driving inclined-plane, upper bolster 1 are provided with driving sliding block 7 to the driving wedge 8 close to the movement of the direction of forming blocks 4.Driving wedge 8 is close
The side of sliding block 7 is provided with the spacing breach 81 being engaged with sliding block 7.It is provided with and drive close to the driving inclined-plane side of sliding block 7 on die shoe 2
The driving chamber that dynamic wedge 8 is engaged.It is provided with die shoe 2 in side of the sliding block 7 away from driving wedge 8 and promotes sliding block 7 to close
The horizontal spring 9 of the direction of driving wedge 8 motion.
Process is：When upper mould moves down driving wedge 8 insert die shoe 2 in driving chamber in, so as to drive sliding block 7 to
Moved close to the direction of forming blocks 4, sliding block 7 ejects forming blocks 4 upwards；As upper mould continues to move down, the punching press on material of drift 3
