Accompanying drawing explanation
Fig. 1 is cutaway view of the present utility model;
Fig. 2 be in Fig. 1 A-A to partial sectional view.
The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the utility model.
As shown in the figure, a kind of adjusting device of press connecting rod length, comprise link 1, wedge 2, adjusting screw(rod) 3, motor 4 and computer control system, the bottom of the connecting rod 5 in forcing press is bolted to connection in link 1, being used for the fixedly sowblock 6 of patrix is arranged in link 1 and slides up and down and coordinate with link 1, the lower surface of connecting rod 5 is horizontal plane 51, the upper surface of sowblock 6 is the downward angled end-face 61 that is tilted to the right, between the angled end-face 61 of the horizontal plane 51 of connecting rod 5 lower ends and sowblock 6 upper ends, form wedge shape space 11, the shape of the shape of wedge 2 and wedge shape space 11 matches and is positioned at wedge shape space 11, in the horizontal plane 51 of connecting rod 5 lower ends, be provided with serrated slot (not marking in figure), the upper surface of wedge 2 has been wholely set sawtooth slide block 21, sawtooth slide block 21 coordinates with serrated slot horizontal slip, in the angled end-face 61 of sowblock 6 upper ends, be provided with dovetail groove (not marking in figure), the lower surface of wedge 2 has been wholely set dovetail slide block 22, dovetail slide block 22 coordinates with dovetail groove horizontal slip, adjusting screw(rod) 3 stretch in link 1 and with wedge 2 bolts, on link 1, be fixedly installed motor mounting rack 12, motor 4 is fixedly connected on motor mounting rack 12, motor 4 is connected with adjusting screw(rod) 3 by shaft coupling 41, between sowblock 6 and link 1, at vertical direction, be provided with locking spring 7, the bottom of sowblock 6 is fixedly installed displacement transducer 62, computer control system comprises A/D converter 8, computer control 9 and D/A converter 10, displacement transducer 62 is electrically connected to A/D converter 8, A/D converter 8 and D/A converter 10 are electrically connected to computer control 9 respectively, D/A converter 10 is electrically connected to motor 4.
In above-described embodiment, the course of work of this adjusting device is: before forcing press work, first regulate the length of connecting rod 5, displacement transducer 62 detects the initial position of sowblock 6, and now motor 4 does not act on, after forcing press is started working, connecting rod 5 and sowblock 6 are because the micro stretching that is heated is long, the initial position that displacement transducer 62 detects sowblock 6 changes, by A/D converter 8, convert the analog signal of change in displacement to data signal input computer control 9, computer control 9 is through computational analysis, by D/A converter 10, convert displacement data signal to analog signal, by Displacement Feedback control program, control the motor 4 reversion number of turns, it is the rotation number of turns of adjusting screw(rod) 3, drive wedge 2 to move to right in the horizontal direction, sowblock 6 under the effect of locking spring 7 thereupon in the vertical direction move, thereby reach the compensation fine adjustment effect to connecting rod 5 and sowblock 6 elongations, the adjusting of realization to height of packing compact, and when connecting rod 5 and sowblock 6 micros in short-term, the action direction of motor 4, adjusting screw(rod) 3, wedge 2, sowblock 6 and connecting rod 5 action direction of micro stretching while growing that be heated is contrary.Because computer control system is to be electrically connected to, the direct action time is much smaller than the time interval between twice punching press, therefore, before upper once punching press, displacement transducer 62 detects again sowblock 6 at initial position, if temperature continues to change, whole adjusting device works on,, On-line Control real-time to height of packing compact have so just been guaranteed, again and again circulation.
