The lower section of the lower diel 12 is additionally provided with multiple buffer units 5, and the buffer unit 5 is symmetricly set on the four of column 4
Week；The buffer unit 5 includes vertical round bar 51, the pipe 52 to match with round bar 51, the circle being arranged inside pipe 52
Column helical spring 53, the piston 54 being arranged inside pipe 52, the capping 55 for being installed in 52 lower end of pipe, stud 56, the circle
The upper end of bar 51 is fixedly connected with lower diel 12, and the lower end of the round bar 51 is arranged in the inside of pipe 52, the cylinder
Helical spring 53 is arranged in the lower section of round bar 51, and the piston 54 is arranged in the lower section of cylindrically coiled spring 53, the capping 55
Center be provided with the screw hole to match with stud 56, the upper end of the stud 56 is fixedly connected with the lower end of piston 54, described
The lower end of stud 56 is arranged in the lower section of capping 55, and the lower end of the stud 56 is installed with handle 561；The lower diel 12
Side be provided with material-pulling device, the material-pulling device includes second hydraulic cylinder 81, U-shaped roller seat 82, transfer roller 83, the transfer roller 83
The roll shaft at both ends is rotatablely connected with the end of roller seat 82, and the telescopic end of the second hydraulic cylinder 81 is fixed with the tail portion of roller seat 82 to be connected
It connects；The other side of the lower diel 12 is provided with inclined plate 6, material collecting tank 7, and the height of 6 upper end of the inclined plate is less than pipe 52
The lower end of the height of upper end, the inclined plate 6 is arranged in the top of material collecting tank 7.
The second hydraulic cylinder 81 is horizontally disposed, and the second hydraulic cylinder 81 can push 83 carry out level of transfer roller to stretch
Contracting movement.The capping 55 is fixedly connected with the lower end of pipe 52, and the upper end of the stud 56 reaches after being threadedly coupled with screw hole
Behind the inside of pipe 52, the upper end of stud 56 is fixedly connected with the lower end of piston 54.The blind hole of the column 4 and 3 top of pedestal
Cooperation can only move up and down to limit lower diel 12.
The raw pieces are placed on the top of lower diel 12, when first hydraulic cylinder 1 drives upper diel 11 downwards
When moving to diel 11 and touching the raw pieces at the top of lower diel 12, as upper diel 11 continues to transport downwards
Dynamic, the lower diel 12 also moves downward therewith, when the lower end of column 4 touches the bottom hole of blind hole, the lower punching press
Mold 12 can not continue to move downward, and upper diel 11 at this time continues to pressure and makes diel 11, lower stamping die
Tool 12, which can mold and complete stamping press, obtains finished parts.After the completion of stamping press, the upper diel 11 is in the first liquid
It is moved upwards under the driving of cylinder pressure 1 so that upper diel 11, lower diel 12 can demould.When upper diel 11
When returning to initial position, at this point, second hydraulic cylinder 81 starts that transfer roller 83 is driven to carry out horizontal stretching motion；The lower diel
12 height at the beginning at the top of it can be equal with the height of the central axes of transfer roller 83.When the body of roll of transfer roller 83 touches lower punching press
When the top of mold 12, as transfer roller 83 pushes advance by second hydraulic cylinder 81, transfer roller 83 can squeeze lower diel 12 and promote
Lower diel 12 moves downward so that cylindrically coiled spring 53 is compressed, the top of transfer roller 83 and lower diel 12 it
Between remain and be adjacent under the action of cylindrically coiled spring 53, as transfer roller 83 continues to promote, 12 top of lower diel
Finished parts are released from the top of lower diel 12 and fallen on from inclined plate 6 by transfer rollers 83, and under gravity, finished parts are final
It falls in material collecting tank 7；Then, under the action of second hydraulic cylinder 81, the transfer roller 83 returns to initial position, in this way, described push away
The pusher operation of material device finishes.When finished parts are very thin, if without the cooperation of buffer unit 5, the transfer roller 83 at
If just it is easier that finished parts can not be released by transfer roller 83, to omit not as enough frictional force between product part.
Therefore, under the cooperation of buffer unit 5 so that for material-pulling device in carrying out pusher operation process, the transfer roller 83 can be always
It is close to the top of lower diel 12, it is ensured that the finished parts at 12 top of lower diel are pushed out, and are avoided omitting, are implemented effect
Fruit is good.Wherein, the height of 6 upper end of the inclined plate be less than 52 upper end of pipe height, this make inclined plate 6 will not hinder round bar 51 into
Row moves up and down.Therefore, the punching mechanism, without carrying out manual cleaning, not only increases work after the completion of stamping press
Efficiency, while safety also significantly improves.
Further, the body of roll of the transfer roller 83 is provided with decorative pattern 831.The presence of the decorative pattern 831 can significantly improve
Frictional force between the finished parts at 12 top of the body of roll of transfer roller 83 and lower diel, to be conducive to 12 top of lower diel
Finished parts be pushed out.
Further, the outside of the pipe 52 is installed with multiple support legs 57, and the support leg 57 is L-shaped, the branch
The bottom of spike 57 is installed with backing plate 571.The support leg 57 is for support pipe 52, additionally it is possible to so that under pipe 52
There are enough spaces to be used for operating handle 561 between end and ground.
Further, it is clearance fit to reduce resistance, between the column 4 and blind hole.The round bar 51 and pipe 52
Inner cavity between be clearance fit.
When the thickness of raw pieces or finished parts changes, when as thinning such as the thickness of finished parts, after the completion of stamping press, institute
It states diel 11 and returns to initial position, when the transfer roller 83 is pulled to the top of lower diel 12, the transfer roller 83
The body of roll and finished parts between there are gaps, the transfer roller 83 can not complete pusher operation.Further, it is arranged in the blind hole
There are minimum of one standard cushion block 9, the standard cushion block 9 to be arranged in the underface of column 4.By placing several marks in blind hole
Quasi- cushion block 9, then by swing handle 561 so that piston 54 moves upwards, piston 54 moves upwards while driving cylindrical screw
Spring 53 moves up, this makes the height of the initial position of the lower diel 12 get higher, even if the thickness of finished parts becomes
Thin, the transfer roller 83 can also complete pusher operation；Wherein, the standard cushion block 9 is a cylindrical metal block, passes through control
The quantity of blind hole Plays cushion block 9 so that lower diel 12 be when that can not move downward, the lower end of the round bar 51 with
There are enough spacing between piston 54, cause to damage to avoid the cylindrically coiled spring 53 from being overly compressed, extends cylinder
The service life of helical spring 53.Therefore, the punching mechanism can be used in the raw pieces or finished parts of a variety of different-thickness
Stamping press, while its blanking operation is not influenced, have a wide range of application, implementation result is good.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
