Two drift guide plates 56 are respectively arranged with, offer guide groove as shown in Figure 3 and Figure 4, on drift guide plate 56 (does not mark in figure
Show), drift mounting blocks 53 are oriented to slip in guide groove, and then the slip to drift mounting blocks 53 serves spacing effect,
It ensure that precision and stability during punching press.
In the present embodiment, pedestal 1 on be fixed with the mounting seat 19 that size is less than pedestal 1, be provided with mounting seat 19
The mounting plane 11, upper stopper 12 and lower block 13 be arranged on mounting seat 19 on, mounting seat 19, pedestal 1 and cam 52 it
Between enclose and set to form the accepting groove 16, and then can be by adjusting the position relationship between pedestal 1, mounting seat 19, cam 52, you can
Realize the change to the size position of accepting groove 16.It is, of course, also possible to using pedestal 1 and 15 integrally formed design of mounting seat, together
Sample can reach the purpose that accepting groove 16 is formed between cam 52.
When motor 51 works, the cam 52 being connected with motor shaft 512 is driven to rotate so as to be driven and coordinate with cam 52
The roller 541 of Cam Follower 54 moved back and forth by the effect of the power of cam 52 along pressing direction, Cam Follower 54
On roller 542 with moving back and forth；Then by effect of the roller 542 to the power of drift mounting blocks 53, roller 542 is to drift
The effect of the applying power of mounting blocks 53, so as to drive upper punch 21 on drift mounting blocks 53 or low punch 31 along pressure direction back and forth
It is mobile, and then by the control to motor 51, realize the purpose to upper punch 21 and the change of the position of low punch 31,
The rotation direction and rotating speed for alloing the upper punch assembly 2 and low punch assembly to pass through the motor shaft 512 to motor 51
Control, you can realize effective control to upper punch 21 and the moving direction of low punch 31 and translational speed so that this into
The machining accuracy and process velocity of circle processing unit (plant) are effectively lifted.
As optional embodiment, as shown in fig. 6, also inserted with bearing (ball) cover 581, the axle in the mounting hole 17
The small column part of the external diameter of socket end lid 581 is plugged in mounting hole 17, and the big cap portion of external diameter supports the outer surface of pedestal 1,
Mounting hole 17 is exited to limit bearing 58；Motor shaft 512 is fixed by driving key 59 and is plugged in power transmission shaft 57.
As optional embodiment, response agency 55 includes support 551, returning spring 552 and replys pull bar 553, branch
Frame 551 is fixedly mounted on pedestal 1, replys being plugged in support 551 by the activity of returning spring 552 of pull bar 553；Drift is pacified
Connecting shaft 531 is fixedly installed on dress block 53, is connected between connecting shaft 531 and reply pull bar 553 by floating junction 554,
Response agency 55 applies the elastic-restoring force opposite with pressing direction to drift mounting blocks 53, and then drift mounting blocks 53 are had
Have towards the opposite movement tendency of pressing direction so that when the Cam Follower 54 on drift mounting blocks 53 does not pass with cam 52
During dynamic contact, Cam Follower 54 is moved by the effect of drift mounting blocks 53 towards cam 52, that is, ensure that cam following
Contact condition is constantly between device 54 and cam 52, so as to avoid between cam 52 and Cam Follower 54 between generation idle running
Away from, and collision rift abrasion between the two is caused, while control accuracy is ensured, improve cam 52 and Cam Follower 54
Service life, reduce the noise sent during collision.
Present embodiment into circle processing unit (plant) work when, workpiece to be processed 200 transmits from the connecting bridge 300 of a upper station
Working position is sent to along the feeding channel between upper punch 21 and low punch 31 into circle processing unit (plant), workpiece to be processed 200,
The drive device work of low punch assembly is driven first, and the driving of motor 51 drives 31 upward punching press of low punch, now precompressed
Projection 311 supports workpiece to be processed 200 to move upwards, until in the pre- indent 121 of insertion that precompressed projection 311 is adapted to, and then it is complete
The pre- U stamping process of carry out of paired workpiece to be processed 200；Then motor 51 drives low punch 31 to move down reset, drives
The drive device of dynamic low punch assembly is stopped, while drives the drive device of upper punch assembly 2 to work, its motor 51
Drive and drive 21 downward punching press of upper punch, the upper groove in upper punch 21 is adapted with liftout mandrel 421, with to workpiece to be processed
200 upper half is carried out into U；Then upper punch 21 keeps stamping position, 31 upward punching press of low punch, by low punch 31
Cooperation between low groove 312 and liftout mandrel 421, to carry out the lower half of workpiece to be processed 200 into U, now complete
Copper sheet Cheng Yuan, obtain into circular Curve；Subsequent upper punch 21 and low punch 31 reset, and liftout mandrel 421 moves along ejection direction,
Set movement is crossed towards full circle into circular Curve on liftout mandrel 421 to drive, and eventually passes through full circle and crosses set to reach full circle
Purpose, obtain final finished work-piece；Last liftout mandrel 421 resets, and finished work-piece can not due to the effect of non-return ring 412
As liftout mandrel 421 bounces back, and then depart from liftout mandrel 421 and drop, that is, realize discharging.
Obviously, above-described embodiment is only intended to clearly illustrate example, and is not the restriction to embodiment.It is right
For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of change or
Change.There is no necessity and possibility to exhaust all the enbodiments.And the obvious change thus extended out or
Among changing still in the protection domain of the invention.
