The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Fig. 1 is a hydraulic cutter mechanism schematic diagram.
As shown in the figure, the invention provides the truss cutting to length mechanism of the full-automatic truss production line of a kind of numerical control, described truss cutting to length mechanism comprises: shear the muscle 30 that winds up of truss 20 the upper cutter device, shear the lower cutter device of 20 two lower edge muscle 31 of truss, drive the drive unit of upper cutter device and lower cutter device respectively;
Described upper cutter device is arranged on the both sides of the muscle 30 that winds up, and its structure comprises: be hinged on the last jointed shaft 8 first on shear arm 7 on the shear arm 3 and second; The described jointed shaft 8 of going up is fixed on the frame (figure does not show).
Last jointed shaft 8 one sides first on the shear arm 3 and second end of shear arm 7 be fixed with first upper cutter 2 and second upper cutter 9 respectively, described first upper cutter 2 and second upper cutter 9 are symmetricly set on muscle 30 both sides of winding up.
Last jointed shaft 8 opposite sides first on the end of shear arm 7 is hinged respectively on the shear arm 3 and second has a two-way drive unit that moves back and forth.
Described lower cutter device is arranged on the both sides of two lower edge muscle 31, and its structure comprises: distinguish the hinged first lower scissors arm 17 and the second lower scissors arm 12 on first time jointed shaft 16 and second time jointed shaft 13; Described first time jointed shaft 16 and second time jointed shaft 13 symmetry are fixed on the frame of truss 20 both sides.
Be fixed with first lower cutter 1 and second lower cutter 10 respectively in the first lower scissors arm, 17 ends of first time jointed shaft 16 1 side with in the second lower scissors arm, 12 ends of second time jointed shaft 13 1 side, described first lower cutter 1 and second lower cutter 10 are symmetricly set on the both sides of two lower edge muscle 31.
In the first lower scissors arm, 17 ends of first time jointed shaft 16 opposite side with hingedly respectively in the second lower scissors arm, 12 ends of second time jointed shaft 13 opposite side have two-way second drive unit 15 that moves back and forth.
