Abstract
The invention discloses a dual-purpose auxiliary pushing device for a pipe bending machine. The auxiliary pushing device is arranged on a rack of the pipe bending machine, is positioned behind a pipe bending die and comprises an auxiliary pushing die sleeve, an auxiliary pushing plate, an auxiliary pushing connection block and an auxiliary pushing oil cylinder; the axis of the auxiliary pushing oil cylinder is horizontally arranged; a cylinder body of the auxiliary pushing oil cylinder is fixed with the auxiliary pushing die sleeve and a piston rod of the auxiliary pushing oil cylinder runs through the auxiliary pushing die sleeve; the auxiliary pushing connection block is fixedly arranged on the piston rod in a detachable manner; the auxiliary pushing plate is fixedly connected with the auxiliary pushing connection block; supporting rollers for supporting the auxiliary pushing plate to horizontally reciprocate are rotationally arranged on the auxiliary pushing die sleeve; an elastic resetting part is arranged between the auxiliary pushing connection block and the auxiliary pushing plate. The auxiliary pushing device not only can be suitable for the fine pipe bending requirement of a thin-wall bent small-radius steel pipe, but also is suitable for the rapid pipe bending requirement of a thick-wall bent large-radius steel pipe.
Description
Technical field
The present invention relates to a kind of auxiliary pull apparatus, refer to a kind of dual-purpose auxiliary pull apparatus of bending machine especially.
Background technology
The auxiliary pull apparatus of bending machine is the vitals on bending machine, after steel pipe charging, the position to be curved of steel pipe enters into the bending die position of bending machine, rotation is clamped by inside and outside bending die, now the rear at steel pipe position to be curved needs the auxiliary steel pipe promotion steel pipe that compresses of auxiliary pull apparatus to move forward, auxiliary pull apparatus can prevent steel pipe from offseting, and ensures the bend pipe precision of steel pipe.
The auxiliary pull apparatus of current bending machine mainly comprises and auxiliaryly pushes away die sleeve, auxiliary push pedal, auxiliaryly push away contiguous block and auxiliary push oil cylinder, described auxiliary push away the dynamic device of die sleeve drive can with action on steel pipe sagittal plane, the cylinder body of auxiliary push oil cylinder is then be fixed on the auxiliary rearward end pushing away die sleeve, piston rod forward through auxiliary push away die sleeve after connect and auxiliaryly push away contiguous block, the auxiliary contiguous block that pushes away is connected with auxiliary push pedal again, like this when needs carry out auxiliary pushing away to steel pipe, power set drive the auxiliary die sleeve that pushes away along the action of steel pipe radial direction, auxiliary push pedal is made to compress steel pipe, then auxiliary push oil cylinder action drives auxiliary push pedal auxiliary pushing steel pipe forward motion.There is defect in right this auxiliary pull apparatus: because auxiliary push pedal drives by auxiliary push oil cylinder, and the piston rod running and comparing of auxiliary push oil cylinder is slow, slow in one's movements when particularly auxiliary push pedal resets, and therefore, constrains the efficiency of bend pipe; Particularly to heavy wall, steel pipe that bending radius is large carry out bend pipe time, restrict more obvious.
Summary of the invention
Technical problem to be solved by this invention is: the dual-purpose auxiliary pull apparatus providing a kind of bending machine, the meticulous bend pipe requirement of this auxiliary pull apparatus steel pipe that not only applicable wall buckling radius is little, but also is suitable for the quick bend pipe requirement of the large steel pipe of heavy wall bending radius.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of dual-purpose auxiliary pull apparatus of bending machine, described auxiliary pull apparatus to be installed in bending machine frame and to be positioned at the rear of bending die, comprise and auxiliaryly push away die sleeve, auxiliary push pedal, auxiliaryly push away contiguous block and auxiliary push oil cylinder, the axis horizontal of described auxiliary push oil cylinder is arranged, the cylinder body of described auxiliary push oil cylinder and the auxiliary die sleeve that pushes away are fixed and piston rod runs through described auxiliaryly pushes away die sleeve, the described auxiliary contiguous block that pushes away is removably fixed on piston rod, described auxiliary push pedal is fixedly connected with the auxiliary contiguous block that pushes away, this is auxiliary pushes away support roller die sleeve being rotatablely equipped with and supporting auxiliary push pedal horizontal reciprocating movement, this auxiliary pushing away between contiguous block and auxiliary push pedal is provided with elastic reset part.
As the preferred scheme of one, described elastic reset part is a back-moving spring, and one end of this back-moving spring is fixed and auxiliaryly pushed away on contiguous block, and the other end is fixed on auxiliary pushing away on die sleeve.
As the preferred scheme of one, the described auxiliary contiguous block that pushes away is removably fixed on piston rod by leveling screw.
As the preferred scheme of one, the described auxiliary upper end pushing away die sleeve is provided with roller mounting slot, and the length direction of described roller mounting slot is consistent with auxiliary push pedal length direction, and described support roller rotates and is installed on auxiliary push pedal described in support slot inner support.
After have employed technique scheme, effect of the present invention is: because the described auxiliary contiguous block that pushes away is removably fixed on piston rod, described auxiliary push pedal is fixedly connected with the auxiliary contiguous block that pushes away, this is auxiliary pushes away support roller die sleeve being rotatablely equipped with and supporting auxiliary push pedal horizontal reciprocating movement, this auxiliary pushing away between contiguous block and auxiliary push pedal is provided with elastic reset part, therefore, when the steel pipe little to the bending radius of thin-walled carries out bend pipe, auxiliary push oil cylinder work, so auxiliary push oil cylinder drives auxiliary push pedal to slide along steel pipe direct of travel, then takes back reset by auxiliary push oil cylinder again.And when the steel pipe that the bending radius of heavy wall is large carries out bend pipe, contiguous block can be pushed away and piston rod separates by auxiliary, because thick-walled pipe itself not easily occurs defect when bending, when thus bending, auxiliary push pedal can have frictional force drive to run forward, and after bend pipe completes, by elastic reset part, auxiliary push pedal can be retracted, the speed that elastic reset part retracts is swift in motion than auxiliary push oil cylinder piston rod, thus efficiency increases, like this, the applicable meticulous bend pipe of this auxiliary pull apparatus and quick bend pipe, the better processing request adapting to client.
