Detailed description of the invention
As shown in Figure 1, 2, a kind of bender lower die, comprise die holder 10, described die holder 10 upper surface is provided with two modules 11 upwards protruded out, described two modules 11 are arranged symmetrically with about this die holder 10 center line, be split-type structural between described two modules 11 and die holder 10, and two modules 11 are slidably arranged in and die holder 10 make two modules 11 form open-close type to arrange; Described die holder 10 is also provided with the locking unit for module 11 being fixed on arbitrary distance of run position.
Preferably, described die holder 10 upper surface offers T-slot 13, is provided with slide 12 bottom described module 11, and described slide 12 to be stuck in T-slot 13 and to slide along T-slot 13 length direction, described T-slot 13 two ends are provided with baffle plate 16, and described baffle plate 16 is fixed by screws on die holder 10 side; Described module 11 is connected by longitudinal bolt 14 with between slide 12, is provided with stage clip 15 between described module 11 bottom surface and slide 12 upper surface.
Further, described die holder 10 upper surface and module 11 lower surface are processed as coarse tooth bar face, and the tooth bar length direction in this tooth bar face is vertical with the length direction of T-slot 13.
The present invention adopts prefastening bolt 13 stuck-module 11, makes to realize adjustable being fixedly connected with between module 11 with die holder 10, arranges tooth bar face on die holder 10 with the contact surface of module 11 simultaneously, ensures that module 11 can not produce loosening in matched moulds process.
Further, be provided with roller 121 bottom described slide 12, the axis horizontal of this roller 121 is arranged and the bottom surface that the wheel face of roller 121 protrudes slide 12 is arranged.
