Description

A kind of steel bar thick machine

The utility model relates to constructional engineering machinery, and is especially relevant with the steel bar thick machine.

The good ring that reinforcing bar connects in the xoncrete structure directly has influence on the quality of architectural engineering.The method of reinforcing bar connection at present has artificial colligation, welding and mechanical connection several, wherein the mechanical connection method is extensively welcome and is used owing to not welding and connect easy being subjected to, in reinforcing steel bar machinery is threaded, usual way is directly to connect with sleeve in the cutting thread of reinforcing bar head again, though its joint performance of this method of attachment can reach Ministry of Construction's related standard requirements, still may pull in the junction in the tension test.Do not pull when guaranteeing that splice that screw shell connects stretches and break at mother metal in the junction, the steel bar end that should guarantee this screw thread have enough thick, finish this operation with regard to the mechanical energy that requires a kind of steel bar thick like this, at present external steel bar thick machine design is by the straight heading head of oil cylinder piston bar, so require that ejection oil cylinder power is big, volume is big; Simultaneously, its device that clamps reinforcing bar adopts oil gear, complex structure, is unfavorable for reducing production costs and improving work efficiency.

The purpose of this utility model is that a kind of steel bar thick machine will be provided, and it can finish big jumping-up with small oil tank, and its heading anchor clamps are very simple simultaneously, and process operation is very convenient.

The utility model comprise frame, hydraulic system, sliding rod frame, ejector apparatus, heading, chuck, on press from both sides and move back clamp device.Frame is double-deck rectangle frame.Hydraulic system is equipped with in lower floor in frame.Hydraulic system is made up of fuel tank, motor, oil pump, oil cylinder and connection oil pipe, motor connects and high-pressure oil pump in transmission, high-pressure oil pump has oil pipe being communicated with the piston both sides of fuel tank and oil cylinder, the oil cylinder piston bar passes cylinder cap upwards, its top hinges, respectively there is a hinge ear-hang oil cylinder cover both sides, and they are connecting the up and down arm fork of pushing tow ejection device respectively.On the frame upper strata sliding rod frame is housed.Sliding rod frame is made up of two fixed heads, four slide bars and 16 nuts, and two fixed heads are fixed on frame two top, and four slide bars divide two rows to intert between two fixed heads, on the plate offside slide bar termination 16 nuts that tighten up are housed.One of sliding rod frame ejector apparatus is housed.Ejector apparatus is by a fixed hinge seat, one movable hinge seat and four lever arms fork are formed, the fixed hinge seat is fixed on the fixed head of one of sliding rod frame, it has, following two hinge shaft hole and on hinge has respectively, two lever arms are pitched down, the hinges seat is connected on the slide bar by four slip caps, on it also has, following two hinge shaft hole also are connected with respectively, two lever arms are pitched down, the other end of the last lever arm fork that the fixed hinge seat is connected with the hinges seat, hinge on the hinge that pushes up on the oil cylinder piston bar, then the be hinged hinge ear-hang of oil cylinder cover both sides of the other end of the following lever arm fork that their both connect.Heading is contained on the hinges seat.It is by a die holder, two die pieces, a positioning block and two anticreep screws are formed, die holder is fixed on the hinges seat, there is a wedge shape hole clipping at its center, the wedge shape die piece profile that two pairings are closed up and the wedge shape hole clipping of die holder are complementary and are mounted in it, there is a die hole at the center that both close up, and it is open a little horn-like that the die hole is.For preventing to be taken out of the die holder hole clipping by reinforcing bar moving back when folder with module, respectively have a draw-in groove in the two die pieces outside, each card has one to pierce into the anticreep screw that comes from die holder in the draw-in groove.In the square hole clipping of the fixed head central authorities of sliding rod frame other end, chuck is housed.Chuck is made up of two slide blocks and two fixture blocks of wedge shape, and two slide blocks are close to fixed head hole clipping both sides, and its wedge point points to heading, and two fixture blocks are positioned in the middle of two slide blocks, and its wedge point is heading dorsad, and there is a folder hole over against the die hole in the two fixture block central authorities of closing up.Because the reinforcing bar thickness difference that each architectural engineering is used is so a steel bar thick machine often has several secondary apertures different die and fixture block.Clamp device on outside chuck, then being equipped with, last clamp device is by two push rods, a bogie, " L " shape trace, one steps on foot lever and plate washer composition, one of two push rod are connecting two slide blocks of chuck respectively, the other end is connecting two last pivoted arms on the rotating turret respectively, the bull stick of rotating turret is sleeved in two positioning seats on frame upper strata, pivoted arm is then connecting " L " type trace under it, the lower end of this trace is connecting again to be stepped in the middle of the foot lever, step on foot lever one end and step on sole, the other end then twists in the holder that is connected in frame leg side.In order to prevent two fixture block slippages of when folder chuck, move back clamp device on be installed with a plate washer in the connecting rod, its downward dop is close to the termination of two fixture blocks in the chuck.In addition, can be in nature when clamp device and chuck slide block are pressed from both sides and move back the folder situation on not, between horizontal segment with " L " shape trace is set a roof beam in place on the frame upper strata, can add one vertical draw mutually move back the folder spring.

The utlity model has following advantage: 1, augmentor is to adopt the thrust that small oil tank produced, again after the lever that four lever arms forks is formed amplifies (the doubly former thrust of scalable 4-7) with power and produce huge rammer power with steel bar thick, rather than adopt the directly afterburning form of oil cylinder piston, thereby make oil cylinder power reduction, volume reduce, to have reduced cost, structure more compact; 2, chuck adopts mechanical gripping means, rather than external traditional oil cylinder clamping device, thereby makes chuck structure much simple, and cost is also much lower; 3, be equiped with folder and move back clamp device, make that the jumping-up process operation is more convenient, work efficiency more improves.The utility model is described in further detail below in conjunction with accompanying drawing and embodiment:
