As further improvement in the technical proposal, described angle push rod the place ahead is provided with handle, by handle, can control the angle push rod and carry out axial rotation, thereby control the second collision block, puts down or packs up.
As further improvement in the technical proposal, described fuel tank is provided with two, and couples together by flow converter of double-united oil pump.But the concrete structure application reference people of this flow converter of double-united oil pump is in the patent " CN201010112705-flow converter of double-united oil pump of hydraulic bending machine " of first to file, the design is owing to being provided with two fuel tanks, the dynamics of its bending reinforcing steel bar and speed can be controlled by adjusting the fuel tank oil pump capacity, two fuel tanks can have at most 3 different oil pump capacity, thereby it is adjustable to make the speed of bending reinforcing steel bar have 3 class.
As further improvement in the technical proposal, on described frame, be provided with automatically/the foot control change-over switch, described automatically/the foot control change-over switch connects reversing valve core by spring.When automatically/when the foot control change-over switch was beaten to automatic transmission, the hydraulic reinforcing-steel bender was according to the angular bend reinforcing bar that sets; When automatically/when the foot control change-over switch is beaten to the foot control shelves, automatically the spring between/foot control change-over switch and reversing valve core opens, the time length that the hydraulic reinforcing-steel bender is pressed according to pedal is controlled the angle of bar bending, namely by the user, freely control crooked angle, but the angle of the maximum angle of bar bending for being set by the angle push rod.
The invention has the beneficial effects as follows:
Multifunction hydraulic reinforcing bar bender of the present invention is owing to having said structure, can be according to the angle of the Stroke Control bar bending of hydraulic cylinder piston, and can carry out fast angle, very easy to use.This multifunction hydraulic reinforcing bar bender can, for the reinforcing bar of crooked different-diameter size, can make the bar bending moulding, as stirrup skeleton frame rectangular after bending; Also can only to reinforcing bar, carry out first order buckling, purposes is various.
The accompanying drawing explanation
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structural representation of multifunction hydraulic reinforcing bar bender.
The specific embodiment
With reference to Fig. 1, multifunction hydraulic reinforcing bar bender provided by the invention, comprise the frame 1 of fixing each accessory for installation, frame 1 top is equipped with the bending mechanism for bending reinforcing steel bar, bending mechanism is comprised of rotating disk 17, center latch 18 and rotation latch 19, center latch 18 is arranged on rotating disk 17 centers, on rotating disk 17, be provided with a plurality of jacks, jack is different to the distance of center latch 18, can will rotate latch 19 according to the size of reinforcing bar and be arranged in corresponding jack, the distance that makes to rotate latch 19He center latch 18 is suitable for preparing the reinforcing bar of bending.Frame 1 top also is provided with the fixedly young bearing pin 20 of pier of reinforcing bar that matches with bending mechanism.
In frame 1, be fixed with hydraulic jack 2 and fuel tank 21, hydraulic jack 2 connects rotating disk 17 and drives its rotation by driving gear set, fuel tank 21 is by petroleum pipeline 3 connecting fluid compressing cylinders 2, on petroleum pipeline 3, is provided be used to controlling switch valve that hydraulic jack 2 starts and be used to controlling the reversal valve of hydraulic cylinder piston conversion moving direction.Further, described fuel tank is provided with two, and couple together by flow converter of double-united oil pump, but the concrete structure application reference people of this flow converter of double-united oil pump is in the patent " CN201010112705-flow converter of double-united oil pump of hydraulic bending machine " of first to file, the design is owing to being provided with two fuel tanks, the dynamics of its bending reinforcing steel bar and speed can be controlled by adjusting the fuel tank oil pump capacity, two fuel tanks can have 3 different oil pump capacity, thereby it is adjustable to make the speed of bending reinforcing steel bar have 3 class.In addition, described switch valve and reversal valve are preferably mechanical combination valve, but the concrete structure application reference people of this combination valve is in the patent " CN201020301575-mechanical combination valve " of first to file.
In hydraulic jack 2 the place aheads, be provided with stroke support 4, in stroke support 4, be provided with the first collision block 5 of connecting fluid oil pressuring cylinder piston, first collision block 5 the place aheads are provided with angle push rod 6, on angle push rod 6, be provided with the second collision block 7, but angle push rod 6 axial rotation, make the second collision block 7 put down or pack up, the place ahead of the first collision block 5 and the second collision block 7 is provided with swingable shock rocking arm 8, the ,Qi lower end, stroke the place ahead that the upper end of shock rocking arm 8 is arranged on the first collision block 5 and the second collision block 7 is arranged on reversing valve core 9 the place aheads.Wherein, be expert at position on engineering support 4 of the first collision block 5 and the second collision block 7 can be carried out front and back and regulated.Angle push rod 6 the place aheads are provided with the handle 16 that stretches out outside frame 1, by handle 16, can control angle push rod 6 and carry out axial rotation, thereby control the second collision block 7, put down or pack up.On stroke support 4, also be provided with reversal valve and adjust bolt 13 and switch valve adjustment bolt 14, on frame 1, be provided with rocking bar 15, the corresponding switch valve in the upper end of rocking bar 15 is adjusted bolt 14, and its lower end is by spring connecting valve spool 10.The design's multifunction hydraulic reinforcing bar bender is when bending reinforcing steel bar, the piston forward of hydraulic jack 2 moves and drives rotating disk 17 rotation bending reinforcing steel bars, and promote the first collision block 5 and move forward, the first collision block 5 promotes angle push rod 6, if the second collision block 7 on angle push rod 6 is collapsed state, the first collision block 5 touches shock rocking arm 8 after moving forward longer stroke, clash into rocking arm 8 and trigger reversing valve core 9, the piston conversion moving direction of hydraulic jack 2 reclaims, thereby controls the certain angle of bar bending; If the second collision block 7 on angle push rod 6 is down state, the second collision block 7 moves forward than after short stroke, touching and clashes into rocking arm 8, and triggers the piston recovery that reversing valve core 9 makes hydraulic jack 2, the angle that bar bending is less.Multifunction hydraulic reinforcing bar bender of the present invention is owing to having said structure, can be according to the angle of the Stroke Control bar bending of hydraulic cylinder piston, and can carry out fast angle, very easy to use.
