Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is further described.
Among Fig. 1, Fig. 2, comprise send hydraulic cylinder 1, mount pad 2 to, send frame 3 to, clamping hydraulic cylinder 4, front end clamp mechanism 5, synchronously connection arm mechanism 6, the gathering sill assembly 7 that bends, the assembly 8 that bends, guide pad 9, the frame 10 that bends, the hydraulic cylinder 11 that bends, web rib 12, underframe 13 etc.
As shown in Figure 1 and Figure 2, the present invention is that a kind of web rib of steel truss is sent bending device synchronously to, comprises feed mechanism, front end clamp mechanism 5, rear end clamp mechanism, Clincher.
Feed mechanism comprises to be sent hydraulic cylinder 1, mount pad 2 to and sends frame 3 to, and the piston rod of sending hydraulic cylinder 1 to is hinged on the mount pad 2, and mount pad 2 is fixed on to be sent on the frame 3.
Front end clamp mechanism 5 is fixed on sending on the frame 3 of feed mechanism.Front end clamp mechanism 5 links to each other with clamping hydraulic cylinder 4, and clamping hydraulic cylinder 4 is fixed on to be sent on the frame 3.
The rear end clamp mechanism is fixed on the underframe 13.
Be provided with synchronous connection arm mechanism 6 between the underframe 13 of sending frame 3 and rear end clamp mechanism to of feed mechanism, Clincher is installed on the mid point of synchronous connection arm mechanism 6.
Connection arm mechanism 6 adopts two parallel-crank mechanisms synchronously, two parallel-crank mechanisms comprise two stocks and four quarter butts, four quarter butts are divided into two groups, one group of the hinged formation of per two quarter butts, the mid point of the synchronous connection arm mechanism 6 of the hinged formation in the middle part of two stocks, the two ends of two stocks are hinged with one group of quarter butt respectively, and the pin joint of one group of quarter butt is fixed on to be sent on the frame 3, and the pin joint of another group quarter butt is fixed on the underframe 13.
Clincher comprises the gathering sill assembly 7 that bends, the assembly 8 that bends, guide pad 9, frame 10 and the hydraulic cylinder 11 that bends bend, the frame 10 that bends is installed on the mid point of synchronous connection arm mechanism 6, a bend assembly 8 and the hydraulic cylinder 11 that bends lays respectively at the two ends of the frame 10 that bends, bend and be fixed with guide pad 9 on the piston rod of hydraulic cylinder 11, the assembly 8 that bends is fixed on the guide pad 9, and the gathering sill assembly 7 that bends is installed on the frame 10 that bends and is positioned at a side of the assembly 8 that bends.
