Description
Technical field
The utility model relates to a kind of auxiliary pull apparatus, refers to especially a kind of dual-purpose auxiliary pull apparatus of bending machine.
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, by inside and outside bending die, clamp rotation, 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 skew, guarantees the bend pipe precision of steel pipe.
The auxiliary pull apparatus of bending machine mainly comprises the auxiliary die sleeve that pushes away at present, auxiliary push pedal, auxiliary contiguous block and the auxiliary push oil cylinder of pushing away, described auxiliary push away the dynamic device of die sleeve drive can with steel pipe sagittal plane on move, the cylinder body of auxiliary push oil cylinder is to be fixed on the auxiliary rearward end that pushes away die sleeve, piston rod connects the auxiliary contiguous block that pushes away through auxiliary after pushing away die sleeve forward, 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 to move along steel pipe radial direction, make auxiliary push pedal compress steel pipe, then the auxiliary push pedal auxiliary pushing of auxiliary push oil cylinder action drives steel pipe moves forward.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, restricted the efficiency of bend pipe; While particularly steel pipe heavy wall, that bending radius is large being carried out to bend pipe, restrict more obvious.
Utility model content
Technical problem to be solved in the utility model is: the dual-purpose auxiliary pull apparatus that a kind of bending machine is provided, the meticulous bend pipe requirement of this auxiliary pull apparatus steel pipe that not only applicable wall buckling radius is little, but also the quick bend pipe requirement of the large steel pipe of applicable heavy wall bending radius.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of dual-purpose auxiliary pull apparatus of bending machine, described auxiliary pull apparatus is installed in bending machine frame and is positioned at the rear of bending die, comprise the auxiliary die sleeve that pushes away, auxiliary push pedal, auxiliary contiguous block and the auxiliary push oil cylinder of pushing away, the axis horizontal of described auxiliary push oil cylinder is arranged, the cylinder body of described auxiliary push oil cylinder and auxiliaryly push away that die sleeve is fixed and piston rod runs through the described auxiliary die sleeve that pushes away, 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 auxiliary support roller that is rotatablely equipped with the auxiliary push pedal horizontal reciprocating movement of support on die sleeve that pushes away, this auxiliary pushing away between contiguous block and auxiliary push pedal is provided with elastic reset part.
As a kind of preferred scheme, described elastic reset part is a back-moving spring, fixing auxiliary the pushing away on contiguous block in one end of this back-moving spring, and the other end is fixed on auxiliary pushing away on die sleeve.
As a kind of preferred scheme, the described auxiliary contiguous block that pushes away is removably fixed on piston rod by leveling screw.
As a kind of preferred scheme, the described auxiliary upper end that pushes 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.
Adopted after technique scheme, effect of the present utility model 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 auxiliary support roller that is rotatablely equipped with the auxiliary push pedal horizontal reciprocating movement of support on die sleeve that pushes away, this auxiliary pushing away between contiguous block and auxiliary push pedal is provided with elastic reset part, therefore, when the little steel pipe of the bending radius of thin-walled is carried out to 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 by auxiliary push oil cylinder, takes back reset again.And when the large steel pipe of the bending radius of heavy wall carries out bend pipe, can push away contiguous block and piston rod separates by auxiliary, because thick-walled pipe itself is not prone to defect when the bending, thereby auxiliary push pedal can have frictional force to drive operation forward when crooked, and after bend pipe completes, can auxiliary push pedal be retracted by elastic reset part, the speed that elastic reset part retracts is swift in motion than auxiliary push oil cylinder piston rod, thereby efficiency increases, like this, the applicable meticulous bend pipe of this auxiliary pull apparatus and fast bend pipe, the better processing request that adapts to client.
