Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete
Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other without making creative work
Embodiment belongs to the scope of protection of the invention.
Please refer to Fig.1~3, in the embodiment of the present invention, a kind of flanging die with automatic material jacking mechanism, including rack 1,
Platen 2, cope plate 3, rush block 8, lower die 10 and lower template 11 at upper mold 4, and platen 2 is equipped in the rack 1, is installed on platen 2
There is lower template 11, be equipped with to place the lower die 10 of workpiece 7 in lower template 11, the surface of the lower die 10 is equipped with cope plate
3 and upper mold 4, cope plate 3 and upper mold 4 fixed by trip bolt 5, be equipped in upper mold 4 and flange is carried out to workpiece 7 rush block 8,
The bottom for rushing block 8 is equipped with protrusion, and protrusion, which is arranged on, rushes that end of block 8 away from workpiece, is also equipped with being used in lower template 11
The automatic automatic material jacking mechanism for jacking up workpiece 7, the automatic material jacking mechanism includes mandril 12, fixing sleeve 13 and piston 14, described
Piston 14 is placed in fixing sleeve 13 and is slidably matched with fixing sleeve 13, and spring one is equipped between the bottom of piston 14 and fixing sleeve 13
15, bottom and the piston 14 of the mandril 12 are fixed, and the top of mandril 12 is pierced by outside fixing sleeve 13, and the top of the mandril 12 is
With rushing " L " the shape structure mutually agreed with 8 bottom of block, plane where the top of mandril 12 is less than or is total to the place plane of workpiece 7
Face when lower die 10 is pressed downward by external force driving, rushes block 8 and synchronously moves downward, rush the contact aside of block 8 and workpiece 7 at this time, right
Workpiece 7 carry out flange, while rush block 8 protrusion contacted with the top of mandril 12, drive mandril 12 move downward, spring 1 by
The driving compression of piston 14, when rushing block 8 and moving upwards, spring 1 rebounds, and piston 14 drives mandril 12 to move up and down, due to
Plane where the top of mandril 12 is less than or the place co-planar with workpiece 7 during initial position, workpiece 7 carry out flange it
Afterwards, when mandril 12 sets back, at flange that workpiece 7 can be withstood, workpiece 7 is jacked up, completes automatic material jacking operation.
The pressing plate 9 for workpiece pressing is further fixed at the side position for rushing block 8, block 8 is rushed and moves downwardly to maximum
During travel position, the distance of pressing plate 9 and lower die 10 is equal to the thickness of workpiece 7, can prevent workpiece 7 from being tilted due to external force acts on, make
It is happened into what workpiece 7 was damaged.
The pressing plate 9 is slidably matched with rushing block 8 by dovetail groove, and the side position for rushing block 8 is fixed with fixed block 19, fixed
Block 19 is connected by spring 2 20 with pressing plate 9, and so to the fixed position of pressing plate 9, there is no limit, when rushing block 8 and being pressed downward,
Pressing plate 9 is preferred to be contacted with workpiece 7, workpiece 7 is compressed, and continues to move with rushing block 8 afterwards, spring 2 20 is pressurized, and presses
Plate 9 is moved upwards compared with block 8 is rushed, but still can keep the compression to workpiece 7.
Guide rod 6, the position of guide rod 6 and the pilot hole position in lower template 11 are also equipped on the cope plate 3
It puts opposite.
The air chamber 17 for stored air is equipped in the fixing sleeve 13, piston 14 is placed in air chamber 17 and and air
The sealing cooperation of chamber 17, the bottom opening of fixing sleeve 13 are sealed with capping 18, are equipped in capping 18 and are connected with air chamber 17
Gas nozzle 16, when piston 14 pushes, the air in air chamber 17 is compressed, and air is sprayed from gas nozzle 16 at this time, when spring one
During 15 recovery, piston 14 can be moved upwards synchronously, and piston 14 moves upwards suddenly and causes 12 disfiguring workpiece 7 of mandril in order to prevent
Happen, due to the gas nozzle 16 of setting and air chamber 17, extraneous air can be rapidly entered in air chamber 17 at this time, and is lived
Plug 14 is influenced slowly to move upwards be subject to negative pressure so that mandril 12 smoothly pushes up up and down, is conducive to protect workpiece.
The top of the mandril 12 is made of rubber material.
The gas nozzle 16 is connected by tracheae with ambient atmosphere.
The present invention operation principle be：When lower die 10 is pressed downward by external force driving, rushes block 8 and synchronously move downward, at this time
The contact aside of block 8 and workpiece 7 is rushed, flange is carried out to workpiece 7, while the protrusion for rushing block 8 is contacted with the top of mandril 12, is driven
Mandril 12 moves downward, and spring 1 is compressed by the driving of piston 14, and when rushing block 8 and moving upwards, spring 1 rebounds, piston
14 drive mandrils 12 move up and down, and plane where the top of mandril 12 is less than or is put down with the place of workpiece 7 during due to initial position
Face is coplanar, and after workpiece 7 carries out flange, when mandril 12 sets back, at the flange that can withstand workpiece 7, workpiece 7 is pushed up
Rise, complete automatic material jacking operation, simultaneously because set gas nozzle 16 and air chamber 17, at this time extraneous air can rapidly enter sky
In air cavity 17, and piston 14 is influenced slowly to move upwards be subject to negative pressure so that mandril 12 smoothly pushes up up and down, is conducive to
Protect workpiece.
