The specific embodiment
Shown in Fig. 2-5, large-sized precision V-type bending adjustable mechanism of the present utility model, 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; Described 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 by 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; Described down mold mechanism comprise the mirror image symmetry before, latter two part, 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 constitutes by several vertical voussoirs 12 of sliding and docking with the inclined-plane of horizontal voussoir 3, the die orifice place, top of described counterdie 16 also is connected with inserts 17, to prevent the excessive wear of die orifice, described horizontal voussoir 3 matches with vertical voussoir 12, and described vertical voussoir group all is fixed on the connecting rod 4 by pin by connecting rod 4 serial connections and each vertical voussoir 12 of passing bearing block 10; Described support 14 is provided with ganoid rectangular channel, laterally voussoir group and vertical voussoir group all are positioned at wherein, laterally the voussoir group is fixed on the counterdie 16 by soket head cap screw, the counterdie length dimension is identical with rectangular channel, 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 described rectangular channel is provided with a plurality of flexible member grooves, and the two ends that are installed in the air spring 13 in the flexible member groove are connected with two horizontal voussoirs 3 of mirror image symmetry respectively; Dust board 18 is installed on the extension edge of described counterdie 16, is used to prevent that the sliding surface of vertical voussoir 12 from entering a large amount of foreign material and influencing being free to slide of vertical voussoir 12.
