Screw rod 71 is separately installed on top surface, the upper end of screw rod 71 is connected with handwheel 73, and lower end makes shoulder pole for pressing shoulder pole spring 72
Spring 72 compresses downwards top chock 8.When starting string reinforcing bar before being straightened, as long as rotation handwheel, sheds shoulder pole spring to upper axis
The pressure of seat is held, top chock will be slowly lifted up under the action of pressure spring, and pressure roller and lower compression roller is made to form an opening
Shape goes here and there after reinforcing bar, rotates handwheel, and shoulder pole spring compresses downwards top chock under the press of screw rod, make pressure roller and
Lower compression roller compresses reinforcing bar and is fed forward reinforcing bar.It is designed in this way, can make to thread more convenient, laborsaving.When screw rod adjusts pressure
What should not be pressed is too tight, and otherwise reinforcing bar can be crushed or scratch, and is sent into forward as long as upper and lower two pressure rollers can be made to push down reinforcing bar.
For the ease of the various sizes of reinforcing bar of conveying, it is machined on upper pressure roller one and lower compression roller one, on upper pressure roller two and lower compression roller two
Various sizes of R slot, prevents reinforcing bar from wandering off.
See that Fig. 1 and Fig. 2, aligning mechanism 20 include alignment motor 21 and alignment frame 22, alignment motor 21 is installed on rack 1
Interior, the two end axles of alignment frame 22 are rotatably installed in respectively on the bearing block 23 on the table top of rack 1, and aligning frame 22 is wherein
It is set with belt wheel 1 on the axis of one end, is straightened on the output shaft of motor 21 and is set with belt wheel 2 25, belt wheel 1 and belt wheel 2 25
Pass through V -- belt Drive；Two sides up and down inside alignment frame 22 intersect the curve roller being equipped with for being straightened reinforcing bar respectively
26, and curve roller 26 is to be obliquely installed.In embodiment as shown in Figure 1, alignment frame in two sides up and down respectively install there are three
Curve roller, wherein each curve roller in front and back when being straightened for centering, it is different that remaining four curve roller can be respectively used to alignment
Different curves is adjusted when the reinforcing bar of material, curve roller is to be mounted on the side plate up and down of alignment frame by screw rod, thus curve
The drafts of roller is adjustable.Alignment principle is, when being straightened frame high speed rotation, curve roller is around reinforcing bar also high speed rotation, due to song
Line roller is to be obliquely installed, i.e., has an angle between its axis and reinforcing bar, therefore surround high-speed rotating one side of curve roller of reinforcing bar
Reinforcing bar can be straightened by face, on the other hand can be sent into reinforcing bar to traction mechanism.
See that Fig. 1 and Fig. 2, the concrete-bar straightening-cutting machine of the utility model further include controller (Fig. 1 is not shown into Fig. 7),
Fixed length mechanism 40 includes the upper pressure roller 3 41 and lower compression roller 3 42 worked in coordination, and upper pressure roller 3 41 and lower compression roller 3 42 pass through respectively
In the side of gear housing 1, upper pressure roller 3 41 is the metering that surface is machined with reticulate pattern for respective axis and the rotational installation of bracket 43
Roller, is socketed with encoder on the axis of metering roller, and encoder is connected the length for calculating reinforcing bar automatically with controller；Lower compression roller three
42 are machined with the idler wheel of triangular groove for surface.Metering roller per revolution, encoder can issue signal to controller, automatic to count
It is long；Upper roller surface is machined with reticulate pattern, and the surface of lower compression roller three is machined with triangular groove, so that the combination of a flat slot pressure roller can be true
Guarantor's reinforcing bar is not easy to skid when walking and wander off.
See that Fig. 6 and Fig. 7, cutting mechanism 50 include that support frame, stationary knife 51, blade 52 and hydraulic cylinder 53, support frame include

56, supporting plate 54 is fixedly installed on the table top of rack 1, and stationary knife 51 is fixedly installed in the front side of moving trolley 56, the core of stationary knife 51
Portion is machined with the through-hole 511 passed through for reinforcing bar, and hydraulic cylinder 53 is fixedly installed in the rear side of moving trolley 56 and is changed by electromagnetism
Connect to valve with controller, the piston rod of hydraulic cylinder 53 advance through it is affixed with blade 52 after moving trolley 56,52, blade
In the outlet end of the through-hole 511 of stationary knife 51, preferably there are the gap of 0.1mm or so, hydraulic oil between blade 52 and stationary knife 51
Blade 52 can frustrate the reinforcing bar in through-hole 511 disconnected when the piston rod of cylinder 53 stretches out, and lead between moving trolley 56 and gear housing 1
Cross long tension spring (Fig. 1 is not shown into Fig. 7) connection.When reinforcing bar after alignment reaches the cut lengths of setting, controller is meeting
The piston rod for controlling hydraulic cylinder stretches out, and blade can frustrate reinforcing bar disconnected.The movement of hydraulic cylinder is changed from controller to electromagnetism
It issuing and instructs to valve, solenoid directional control valve is connected to instruction, and coil is powered, and electromagnetic actuation in coil, reversal valve valve rod acts at once,
Reversal valve oil circuit is opened, and pressure oil is quickly filled with to hydraulic cylinder, and piston rod is impacted by high pressure oil, and moment forward extends out, blade
Reinforcing bar is frustrated to disconnected, solenoid directional control valve coil losing electricity in a flash, oil circuit is closed, stops supplying to hydraulic cylinder by electromagnet release valve rod
Oil, the compressed spring being sleeved on piston rod in oil cylinder lose ambient pressure and open rapidly and reset the quick pusher of piston rod,
The only several seconds time of zero point has quickly completed a shear action, speed is exceedingly fast, ultrahigh in efficiency.Since oil cylinder is from piston
Bar, which stretches out cutting reinforcing bar and resets to piston rod retraction, a time difference, therefore the reinforcing bar being aligned can withstand moving trolley in light
A distance of walking on bar axis can make shearing trolley return to original rapidly in the case where losing thrust by the way that long tension spring is arranged
It awaits orders on ground.
