BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an arrangement of a knee lever mechanism of a pressing unit with the possibility of shaping the course of a basic pressing force according to the characteristics of a technological operation.
To date, the known press unit mechanisms are generally flat, cranked, eccentric, knee, lever and cam drives with direct or rotary motor drive. Mechanisms with this arrangement are known to characterize the basic compression force and compression rates. In addition, in the presses and dies used for precise cutting and trimming, mechanisms are specifically applied, the arrangement of which is determined by the combination of the simple mechanisms exerted above. These retain the characteristic course of the basic force, but, on the other hand, they have greater utilization of the working stroke and the course of the pressing speed to better meet the technological requirements. In general, in rare cases, the course of the basic pressing force meets the requirements of the characteristics of the forming operations. In particular, this requirement for shaping the base pressing force is exerted on the assembly units for assembly where the characteristics of the forming operations are very diverse.
The mechanism of the invention overcomes the drawbacks of the above-mentioned solutions and allows the shaping of the basic compression force. The essence of its arrangement is that the ram is connected via a slide joint, a connecting rod, a knuckle, a rocker arm, a rocker arm with a first cranked pivot lever mounted in a bearing, and a knee rod connected at one end with a connecting rod and a rocker in the knee joint is at the other end, hingedly connected to the second lever rotatably mounted in the bearing. The interconnection of the two levers is transferred by the rod and the hinges. The press unit mechanism is driven through the lever types by a linear motion motor. An important feature of the arrangement of the mechanism according to the invention is that it makes it possible to shape the course of the basic pressing force by varying the length of the shank rod, changing the length of the rod connecting the free ends of the levers, and moving the joint connecting the knee rod to the second lever.
Changing the length of the knee rod and changing the length joining the free ends of the levers is advantageous so that the rods are split, provided with an adjusting member and a member for securing the length of the rods. The joint connecting the elbow rod to the second lever is preferably located on the slider member displaceable on the second lever. The position of the displacement member on the conduit lever is enhanced by known bleaching.
Figure 1 shows an example of an arrangement of a press unit mechanism according to the invention. Figure 2 shows the arrangement of the mechanism according to the invention with split rods and with the possibility of moving the joint connecting the elbow rod to the second lever.
The mechanism of Figures 1 and 2 consists of a ram 1 guided in a guide 2 which is connected to the connecting rod 4 in a slide joint 3 and a rocker arm 6 and a knee rod 10 are connected in the knee joint 5. In the rocker arm 7 the rocker B is connected with a crank lever 8 which is rotatably mounted in the bearing 9 and is still connected to the hinge 14 in the hinge 15. The second lever 11, preferably angled, is rotatably supported in the bearing 12, in hinge 13 it is connected to a knee rod 10 and a rod 14 is attached to it in the hinge 16. The lever 11 is connected to the motor 17, preferably by pneumatic or hydraulic, for example, a link 18. On the drawers 10 and 14, the adjusting members 19 and 19 '(FIG. 2) and the locking members 20, 20 for securing the adjusted rod length. On the second lever 11, the hinge 13 is disposed on the feed member 21 provided by a known grip.
The function of the mechanism of Figures 1 and 2 according to the invention is as follows. The straight-line motor 17, through the link 18, feeds the lever 11 around the bearing 12. The end of the lever 11 through the pivot 16, the rod 14 and the pivot 15, swings the crank lever 8, around the bearing 9 in a kink whereby the pivot 7, rocker 6, knee joint 5, the rod 4 and the slide joint 3 move the ram 1 in the guide 2. At the same time the movement on the slide 1 is transferred from the lever 11 through the hinge 13, the knee rod 10, the knee joint 5 with the rocker 6, the connecting rod 4 and the slide joint 3.
Shaping the course of the basic compression force in the constructed mechanism with the respective length ratios of the individual members is carried out by changing the length of the knee rod 10, changing the length of the rod 14 connecting the lever and adjusting the joint 13 located on the slider 21 after the lever 11. Position of the feed member 21, the rod length device 10, 14 and their provision is made according to the desired characteristics of the technological operation,
In Fig. 1, the slice position of the mechanism function is indicated in a dashed line.
The mechanism according to the invention can be used in the construction of mechanical presses and assembly press units with a variety of forming and assembly characteristics.
