Technical field

The utility model relates to a kind of construction machinery equipment, the curved unit mahine of cutting of particularly a kind of fluid pressure type building iron.

Background technology

In building engineering construction, reinforcing bar will be processed into the skeleton that different shapes is used as cement components usually at present, existing bar bending, cutting-off method are: 1, adopt manpower to carry out bar bending, cut-out, time-consuming, the effort of this mode; 2, adopt bending machine and two kinds of equipment of cutting machine to carry out respectively, but its equipment investment is big, area occupied is many, complex operation is difficult to meet present people's production requirement; Occurred afterwards a kind ofly curved cutting dual-purpose unit mahine, but its inefficiency, angle of bend are inaccurate, and can not automatically reset after the bending, control complexity, be difficult to obtain people and use widely.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, easy to operate fluid pressure type building iron the curved unit mahine of cutting.

The technical scheme that its technical problem that solves the utility model adopts is:

The curved unit mahine of cutting of a kind of fluid pressure type building iron, it comprises casing, the bending mechanism and the shut-off mechanism that are driven by transmission device are installed in the casing, described bending mechanism comprises rotating disk and the holder that is used for moment reinforcement, shut-off mechanism includes and is arranged on the outer fixed cutting tool of casing, and the moving cutting knife that is used with fixed cutting tool, described transmission device comprises hydraulic cylinder, piston rod on the hydraulic cylinder tooth bar that has been fixedly connected, tooth bar is provided with the gear that cooperatively interacts with it, gear shaft on the gear passes casing and is connected with rotating disk, the end of described tooth bar is connected with rocking arm; the other end of rocking arm is fixedly hinged on the casing, and described rocking arm and moving cutting knife flexibly connect;

As improvement of the technical scheme, be provided with guide rail in the described casing for the tooth bar side-to-side movement;

As further improvement in the technical proposal, flexibly connect by axle between described tooth bar and the rocking arm, the left and right sides of axle be provided with can side-to-side movement in guide rail deflector roll.

The beneficial effects of the utility model are: this product uses hydraulic cylinder to drive shut-off mechanism and bending mechanism simultaneously, thereby make and on a machine, have bending simultaneously, shear two kinds of functions, and this product has simple in structure, convenience operation, thereby is widely used on building iron bending, the shearing manipulation.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, the curved unit mahine of cutting of a kind of fluid pressure type building iron, it comprises casing 1, the bending mechanism 3 and the shut-off mechanism 4 that are driven by transmission device 2 are installed in the casing 1, described bending mechanism 3 comprises rotating disk 31 and the holder 32 that is used for moment reinforcement, described rotating disk 31 is provided with pin hole, and the client can be equipped with latch according to the diameter of reinforcing bar and crooked radian in corresponding pin hole; Described shut-off mechanism 4 includes the fixed cutting tool 42 that is arranged on outside the casing 1; and the moving cutting knife 41 that is used with fixed cutting tool 42; described transmission device 2 comprises hydraulic cylinder 5; piston rod 51 on the hydraulic cylinder 5 tooth bar 6 that has been fixedly connected; be provided with guide rail 11 in the described casing 1 for tooth bar 6 side-to-side movements; tooth bar 6 is provided with the gear 7 that cooperatively interacts with it; gear shaft 71 on the gear 7 passes casing 1 and is connected with rotating disk 31; the end of described tooth bar 6 is connected with rocking arm 8; flexibly connect by axle 9 between described tooth bar 6 and the rocking arm 8; axle 9 the left and right sides be provided with can side-to-side movement guide rail 11 in deflector roll 12; other end of rocking arm 8 is fixedly hinged on the casing 1; described rocking arm 8 flexibly connects with moving cutting knife 41; the utility model is not limited to above-mentioned embodiment certainly; can also adopt the identical version of other function, needs only it and reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.

Operation principle of the present utility model is: the driven by motor oil pump provides pressure oil to hydraulic cylinder 5, move right thereby produce power and promote tooth bar 6 by the piston rod on the hydraulic cylinder 5 51, the gear 7 that cooperatively interacts with it simultaneously rotates, and drives rotating disk 31 moment reinforcements by gear shaft 71; In addition, when tooth bar 6 moved right, the rocking arm 8 of Huo Donglianjieing rotated around the fulcrum that is hinged on casing 1 with it, also moved right thereby order about moving cutting knife 41, and was used the purpose that reaches shear reinforcement with fixed cutting tool 42; Otherwise when the piston rod on the hydraulic cylinder 5 51 bounced back backward,

tooth bar

6 and 41 whiles of moving cutting knife were to left movement and be returned to original state.Go round and begin again, thereby realized coming back bending to cut the purpose of reinforcing bar.

The utility model makes equipment in order to guarantee rapidly automatic reverse of hydraulic system Each angle of bend is consistent, accurately, can also in casing 1, liquid be installed Press bending machine knocking type linkage combination valve, the use of linkage combination valve can also realize the worker Make the gear shift of speed, the control of angle of bend, the functions such as control of bar cutting; In addition Outward, this product also has simple in structure, easy to operate characteristics, thus extensive use On building iron bending, shearing manipulation.
