Technical field
The utility model relates to a kind of auxiliary pull apparatus, refers to especially the auxiliary pull apparatus of using on a kind of bending machine.
Background technology
The auxiliary pull apparatus of bending machine is the vitals on the bending machine, after the steel pipe charging, the position to be curved of steel pipe enters into the bending die position of bending machine, clamp rotation by inside and outside bending die, the rear at steel pipe this moment 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 the 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, the described auxiliary dynamic device of die sleeve that pushes away drives and can move to vertical plane with steel shaft, the cylinder body of auxiliary push oil cylinder then is to be fixed on the auxiliary rearward end that pushes away die sleeve, piston rod passes forward auxiliary pushing away and connects the auxiliary contiguous block that pushes away behind the die sleeve, the auxiliary contiguous block that pushes away is connected with auxiliary push pedal again, the auxiliary contiguous block that pushes away with syndeton between the auxiliary push pedal is: an auxiliary end that pushes away contiguous block is connected with the piston rod bolt, the end of the other end and the downside of auxiliary push pedal are close to, then twist to the auxiliary end that pushes away contiguous block downwards from the upper side of auxiliary push pedal by bolt, like this when needs carry out auxiliary pushing away to steel pipe, power set drive the auxiliary die sleeve that pushes away and move along the 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 are 2 deficiencies in said structure: 1. because the cylinder body of auxiliary push oil cylinder is to be fixed on the auxiliary rearward end that pushes away die sleeve, therefore, auxiliary push oil cylinder has consisted of cantilever design with respect to the auxiliary die sleeve that pushes away, the unbalance stress of auxiliary like this push oil cylinder, easy and horizontal direction is offset, so not only affected the service life of auxiliary push oil cylinder, and auxiliary push oil cylinder drives auxiliary push pedal campaign and also have some setbacks, may affect the bend pipe precision; 2. because the auxiliary bolt that pushes away between contiguous block and the auxiliary push pedal is to be screwed under the upper side picture of auxiliary push pedal in the auxiliary end that pushes away contiguous block, therefore, easy and the horizontal direction generation deviation of auxiliary push pedal, cause the depth of parallelism of the piston rod of auxiliary push pedal and auxiliary cylinder to descend, cause equally auxiliary push pedal operation not smooth, affect the bend pipe precision.
The utility model content
Technical problem to be solved in the utility model is: a kind of bending machine auxiliary pull apparatus is provided, and the cantilever force that the auxiliary push oil cylinder of this auxiliary pull apparatus is subject to is little, thereby longer service life is moved more steadily, improves the bend pipe precision.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of bending machine auxiliary pull apparatus, described auxiliary pull apparatus is installed on the 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, described auxiliary push oil cylinder runs through the described auxiliary die sleeve that pushes away, the cylinder body of described auxiliary push oil cylinder is fixedly connected with an auxiliary side that pushes away the close bending die of die sleeve, described auxiliary pushing away on the piston rod that contiguous block is fixed in described auxiliary push oil cylinder, described auxiliary push pedal is fixedly connected with and drives horizontal direction by auxiliary push oil cylinder and move back and forth with the auxiliary contiguous block that pushes away.
As a kind of preferred scheme, the described auxiliary die sleeve that pushes away is provided with installing hole with the steel pipe axially parallel, described auxiliary push oil cylinder penetrating mounting holes, and the lower hole wall of described installing hole supports auxiliary push oil cylinder.
As a kind of preferred scheme, a described auxiliary end that pushes away contiguous block is fixedly connected with the piston rod end of auxiliary push oil cylinder by screw; The described auxiliary contiguous block other end that pushes away vertically inserts in the jack of auxiliary push pedal, and the described auxiliary insertion position of contiguous block that pushes away is near the end of auxiliary push pedal, and the end of described auxiliary push pedal is provided with the fastening described auxiliary bolt that pushes away contiguous block.
After having adopted technique scheme, effect of the present utility model is: because the axis horizontal of described auxiliary push oil cylinder is arranged, described auxiliary push oil cylinder runs through the described auxiliary die sleeve that pushes away, the cylinder body of described auxiliary push oil cylinder is fixedly connected with an auxiliary side that pushes away the close bending die of die sleeve, described auxiliary pushing away on the piston rod that contiguous block is fixed in described auxiliary push oil cylinder, described auxiliary push pedal is fixedly connected with by the reciprocating motion of auxiliary push oil cylinder driving horizontal direction with the auxiliary contiguous block that pushes away, the cylinder body that is to say auxiliary push oil cylinder is to run through auxiliary to push away die sleeve and be fixed on the auxiliary front end that pushes away die sleeve, like this, reduced the suffered cantilever force of auxiliary push oil cylinder, increase the service life, and auxiliary push oil cylinder is difficult for skew, guarantee the piston rod level run of auxiliary push oil cylinder, guarantee the level run precision of auxiliary push pedal, improve the bend pipe precision.
Again because the described auxiliary die sleeve that pushes away is provided with installing hole with the steel pipe axially parallel, described auxiliary push oil cylinder penetrating mounting holes, the lower hole wall of described installing hole supports auxiliary push oil cylinder, therefore, lower hole wall by installing hole supports auxiliary push oil cylinder, and like this, the suffered cantilever force of auxiliary push oil cylinder is less, the piston rod operation of auxiliary push oil cylinder is more steady, improves the precision better effects if of bend pipe.
Be fixedly connected with the piston rod end of auxiliary push oil cylinder by screw owing to a described auxiliary end that pushes away contiguous block again; The described auxiliary contiguous block other end that pushes away vertically inserts in the jack of auxiliary push pedal, the described auxiliary insertion position of contiguous block that pushes away is near the end of auxiliary push pedal, the end of described auxiliary push pedal is provided with the fastening described auxiliary bolt that pushes away contiguous block, therefore, the direction that is screwed into of bolt is screwed into by the end of auxiliary push pedal, and this power that is screwed into can't make auxiliary push pedal occurred level skew, can guarantee like this depth of parallelism between auxiliary push pedal and the auxiliary push oil cylinder, the operation that guarantees auxiliary push pedal is smooth and easy, improves the bend pipe precision.
