Description of drawings
Fig. 1 is a structural scheme of mechanism of the present invention.
Fig. 2 is that E among Fig. 1 is to schematic diagram.
Fig. 3 is the concrete applicable cases schematic diagram of the present invention.
The specific embodiment
Below in conjunction with concrete drawings and Examples the present invention is further described.
Shown in Fig. 1～3, among the embodiment eight station punch presses, comprise guide rail 3, first servomotor 1, ball screw 2 and set of molds 4, output axle head at first servomotor 1 connects ball screw 2, set of molds 4 is spirally connected on the ball screw 2, set of molds 4 is placed on the guide rail 3, and first servomotor 1 drives ball screw 2 rotations, and ball screw 2 drives set of molds 4 translation on guide rail 3.
Described set of molds 4 comprises the mould of at least one station, and the mould of each station includes patrix 5 and counterdie 6, and patrix 5 and counterdie are corresponding and concentric about in the of 6.
Three A stations, three B stations, a D station and a C station are arranged in described station, amount to eight stations, wherein the C station is the mold rotation station.
The mold rotation station is arranged in the described station; Second servomotor 10 is set on described set of molds 4, and the output axle head of described second servomotor 10 is connected with the major axis left end, and the right-hand member of described major axis utilizes worm-and-wheel gear to be connected with described mold rotation.
Described mold rotation has last mold rotation and revolving die next time, and the described mold rotation of going up is positioned on the patrix 5, and described revolving die next time is positioned on the counterdie 6, and, last mold rotation and next time revolving die be positioned on the same one rotating shaft line; Described major axis has first major axis 12 and second major axis 13, and described worm-and-wheel gear has last worm-and-wheel gear and following worm-and-wheel gear; Between the left end of the output axle head of second servomotor 10 and first major axis 12, first synchromesh gear is set, second synchromesh gear is set, utilize between described first synchromesh gear and second synchromesh gear and be with 11 to interconnect synchronously at the left end of second major axis 13; Worm-and-wheel gear is connected with last mold rotation in the right-hand member utilization of described first major axis 12, and worm-and-wheel gear is connected with revolving die next time under the right-hand member utilization of described second major axis 13.
As shown in Figure 3; when carrying out press work; when the corresponding mould punching press of needs; first servomotor 1 drives ball screw 2 rotations; thereby the set of molds 4 in the control die changing mechanism is translation fast on guide rail 3; make corresponding mould move to the attacking head below of main transmission 8, after feed system 9 is delivered to the relevant position with plate simultaneously, begin punching press.
As shown in Figure 2, when using mold rotation, second servomotor 10 is by first major axis 12, the last mold rotation that drives in the patrix 5 through last worm-and-wheel gear rotates, second servomotor 10 is simultaneously by being with 11 synchronously, drive second major axis 13, the revolving die next time that worm-and-wheel gear drives in the counterdie 6 under the warp rotates, and is with 11 to guarantee that upper and lower mold rotation turns round synchronously synchronously.Because the gyration of upper and lower mold rotation is independent of other motions, the rotation that makes mold rotation up and down and feed system level vertically, laterally, the mobile of set of molds can carry out simultaneously, realizes four-axle linked.
