Abstract
A controlled positioning mechanism for tube bending machine is provided. The tube bending is driven by a oil cylinder; two piston rods are positioned on the piston of the oil cylinder; the front piston rod is connected to the driving rack for tube bending; the rear piston rod is configured as screw stem; a nut that can adjust the position of the screw stem is arranged on the screw stem; the position of the nut is driven and determined by a controlled electromotor; the controlled electromotor is configured as a servomotor or a step motor. With the adoption of this utility model, the precision of tube bending can be improved and the production cost can be lowered down.
Description
Technical field
The utility model relates to the processing of metal tube, relates in particular to the bending process equipment of metal tube.
Background technology
The bending process equipment of the metal tube of prior art, as the disclosed a kind of bending machine of Chinese patent CN200420080264.4, Chinese patent CN03259392.9 discloses a kind of bending machine, comprise frame, be fixedly installed on the power drive mechanism on the frame, described frame is provided with the driving wheel mould that can move horizontally, the driving wheel mould connects with power drive mechanism, be provided with two driven slide plate moulds with the corresponding frame of driving wheel mould, two driven slide plate moulds are separately positioned on the die holder, die holder rotates and is arranged on the frame, and the bottom of two die holders links with a power drive mechanism respectively.Chinese patent CN200420027261.4 discloses the retaining that drives tooth bar in a kind of bending machine and has leaned on device, Chinese patent CN200320126873.4 discloses a kind of high accuracy manual tube bender, Chinese patent CN02291314.9 discloses a kind of bending machine lever arm rotating shaft transmission mechanism, Chinese patent CN02291313.0 discloses and has has a kind ofly inserted and put fixing bending machine pipe bending mechanism slide to insert and put panel seat, Chinese patent CN02291312.2 discloses a kind of bending machine spindle drive, and Chinese patent CN03259917.X discloses the thrustor in a kind of bending machine.
In the bending machine of existing employing hydraulic oil cylinder driving, because there is bigger inertia in hydraulic oil cylinder driving, when current operation has put in place, the inertia motion of hydraulic oil cylinder driving will have influence on the precision of whole processing, and the variation of oil temperature also can make the stroke of hydraulic oil cylinder driving be offset in the oil cylinder.Adopt motor-driven bending machine, when needs carried out the processing of larger caliber tubing, though can guarantee precision, equipment cost can improve greatly.The technical scheme of contradiction is to rely on the inertia motion that manually limits oil cylinder between a kind of compromise solution precision and the cost, concrete grammar then is, the piston rod of oil cylinder is transformed into a screw rod or the screw rod of a script prolongation by polished rod, on screw rod, join spacing adjusting nut, by the requirement of operating personnel according to activation point, the position of adjusting nut on screw rod, thereby, when hydraulic oil cylinder driving stops, when piston rod inertia moves ahead, move to certain position by nut and be obstructed and finish the inertia motion of piston rod.
How existing structure is improved, the artificial operation of setting nut is become machinery automatically, prior art does not provide ready-made solution.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art, and the nut location of realizing regulating automatically on the oil cylinder piston bar is located with the control bending machine.
The technical scheme in the invention for solving the above technical problem is, manufacture and design the controlled location mechanism in a kind of bending machine, bend pipe power is hydraulic oil cylinder driving, two piston rods are housed on the piston of oil cylinder, secondary piston bar bridge piece drives tooth bar, the back piston bar is a screw rod, is furnished with the nut that can regulate its position on screw rod, and the position of described nut is driven definite by controlled motor.
Adopt controlling organization, can realize controlling automatically nut location, artificial relatively the setting, precision and efficient can improve greatly.
Described controlling organization comprises motor and transmission mechanism.
Described motor is servomotor or stepper motor.
Described controlling organization and nut are one.
This structure, nut itself are that be enclosed within on the screw rod can the turn position, and controlling organization can be arranged in the housing that contains nut, can move horizontally with the nut turn.
The outline of described nut is provided with the tooth in order to be driven.
Described transmission mechanism comprises cog belt.
Compare with prior art, adopt the controlled location mechanism in the bending machine of the present utility model, for the reduction of the raising of bend pipe precision and production cost provides may.
Description of drawings
Fig. 1 is the structural representation of the controlled location mechanism for implementing example in the bending machine of the present utility model.
The specific embodiment
Be described in further detail below in conjunction with the most preferred embodiment shown in the accompanying drawing.
Controlled location mechanism in the bending machine of the present utility model, as shown in Figure 1, described bend pipe power is that oil cylinder 10 drives, two piston rods are housed on the piston of oil cylinder 10, secondary piston bar bridge piece drives tooth bar 50, and the back piston bar is a screw rod 20, is furnished with on screw rod 20 and can regulates the nut 30 that oil cylinder 10 strokes are controlled in its position, stop collar 41 is housed on the nut 30, during bend pipe, piston moves to left, and is tight with the subsides of oil cylinder rear end face to stop collar 41, tooth bar 50 can't continue to move to left, thereby finishes bend pipe one time.Controlled motor 42 drives nut 30 rotations by cog belt 43 and comes the axial location of mobile stop collar 41 on screw rod 20, thereby realizes the bending pipes operation of different angles.
The most preferred embodiment of the above is intended to specify thinking of the present utility model: make the position adjustments of nut on screw rod controlled.The enforcement of the utility model is not limited to the disclosed mode of above most preferred embodiment, and is all based on above-mentioned mentality of designing, simply deduces and replace, and the controlled location mechanism in the concrete bending machine that obtains all belongs to enforcement of the present utility model.
Claims (2)
