The specific embodiment
Shown in Fig. 2-5, large-sized precision V-type bending adjustable mechanism of the present invention, it comprises the following mold mechanism that places on the support 14, the bearing block 10 that is connected with support 14, in the bearing block 10 transmission mechanism is installed; Said transmission mechanism comprises screw rod 6 and the thrust nut seat 9 that matches with screw rod 6; One end of screw rod 6 is connected to motor 1 through bearing 7 and reduction box 2; The other end is connected to bearing block 10; Thrust nut seat 9 can be along gib block 5 linear slide that are fixed on the bearing block 10, and its two ends are fixedly connected with two connecting rods 4 that parallel with screw rod 6 respectively; Said mold mechanism down comprises former and later two parts of mirror image symmetry; Two parts include counterdie 16, be fixed on the end to end and horizontal voussoir group that constitutes arranged in a straight line by several horizontal voussoirs 3 of counterdie 16 belows and the vertical voussoir group that is made up of several vertical voussoirs 12 of sliding and docking with the inclined-plane of horizontal voussoir 3; The die orifice place, top of said counterdie 16 also is connected with inserts 17; To prevent the excessive wear of die orifice; Said horizontal voussoir 3 matches with vertical voussoir 12, and said vertical voussoir group all is fixed on the connecting rod 4 through pin by the connecting rod that passes bearing block 10 4 serial connections and each vertical voussoir 12; Said support 14 is provided with ganoid rectangular channel; Laterally the voussoir group all is positioned at wherein with vertical voussoir group; Laterally the voussoir group is fixed on the counterdie 16 by soket head cap screw, and the counterdie length dimension is identical with rectangular channel, and its end face slides with support end cap 15 and docks; Vertically the terminal voussoir 11 in the voussoir group keeps at a certain distance away with end cap 15, to guarantee the mobile space of vertical voussoir group; The bottom surface of said rectangular channel is provided with a plurality of flexible member grooves, is installed in the air spring 13 in the flexible member groove
Two ends be connected with two horizontal voussoirs 3 of mirror image symmetry respectively; Dust board 18 is installed on the extension edge of said counterdie 16, is used to prevent that the sliding surface of vertical voussoir 12 from getting into a large amount of foreign material and influencing being free to slide of vertical voussoir 12.
During work, motor 1 drives screw rod 6 through reduction box 2 and rotates, and the thrust nut seat 9 that is mated vertically moves; Thereby drive connecting rod 4 motions; Connecting rod 4 drives the lengthwise movement of vertical voussoir group when moving right, thereby the horizontal voussoir group that promotion is mated laterally moves, and the final counterdie 16 that links together with horizontal voussoir that drives laterally moves; This moment, the counterdie opening diminished gradually, and air spring 13 is compressed; When need transferring big opening, the motor counter-rotating, connecting rod 4 drives vertical voussoir group and is moved to the left, and between the horizontal voussoir group that is mated, forms the gap, and this moment, air spring 13 discharged elastic force, pushed horizontal voussoir and counterdie 13 to rightabout, and it is big that opening promptly becomes.
Large-sized precision V-type bending adjustable mechanism of the present invention drives screw rod through drive motors; Make vertical voussoir realize vertically moving through transmission mechanism then; Do transverse movement through the horizontal voussoir of voussoir pushed, thereby drive the counterdie motion, reach the purpose of step-less adjustment counterdie openings of sizes.The present invention has realized the step-less adjustment of bending mechanism opening portion, and is easy to operate and safe reliable, can increase the kind of producing product, the automaticity that has improved production.
