Abstract
The utility model discloses a kind of cross-roll straightening machine, including upper spider, lower bearing bracket, upper sliding beam, lower slider beam, column and 3 groups of smoothing rolls, upper spider and lower bearing bracket are connected by 8 root posts, upper spider is provided with 3 pressure leading screws, pressure leading screw passes through Motor drive, pressure leading screw is connected with upper sliding beam by feed screw nut, the two ends of upper sliding beam and lower slider beam are enclosed within column by sliding sleeve respectively, the upper straightening roll of 3 groups of smoothing rolls and lower smoothing roll are separately mounted on sliding beam and lower slider beam, multiple locked hydraulic cylinders and multiple auxiliary hydraulic cylinders are installed between upper sliding beam and lower slider beam.Cross-roll straightening machine of the present utility model increased hydraulic lock clamp force by increasing auxiliary hydraulic cylinder, and when its aligning steel pipe is greatly improved, the rigidity and stability of body, realizes good leveling effect, and the outer surface and precision for aligning steel pipe is greatly improved.
Description
Technical field
This utility model belongs to steel pipe's production technical field, relates in particular to a kind of cross-roll straightening machine.
Background technology
Cross-roll straightening machine is that, for aligning steel pipe, the buckling and horizontal section after removing steel pipe forming, welding is not
The defects such as circularity, while eliminating because welding high temperature to the structural stress at steel pipe seam.Existing cross-roll straightening machine is made in long-time
With during, it may appear that frame and roll fastening system rigidly decline, during aligning steel pipe, slide up and down beam and rock, cross roll aligning
Machine rigidity is not enough, and during aligning, smoothing roll is rocked, and affects steel pipe leveling effect.
The content of the invention
The purpose of this utility model is to overcome shortcoming of the prior art, there is provided a kind of cross-roll straightening machine.
For achieving the above object, this utility model is employed the following technical solutions：A kind of cross-roll straightening machine, including upper spider,
Lower bearing bracket, upper sliding beam, lower slider beam, column and 3 groups of smoothing rolls, upper spider and lower bearing bracket are connected by 8 root posts, upper spider
3 pressure leading screws are provided with, pressure leading screw is connected with upper sliding beam by feed screw nut by Motor drive, pressure leading screw, on
The two ends of sliding beam and lower slider beam are enclosed within column by sliding sleeve respectively, and the upper straightening roll of 3 groups of smoothing rolls and lower smoothing roll divide
An Zhuan not go up on sliding beam and lower slider beam, multiple locked hydraulic cylinders and multiple are installed between upper sliding beam and lower slider beam
Auxiliary hydraulic cylinder.
The upper sliding beam is provided with.
The locked hydraulic cylinder and auxiliary hydraulic cylinder are 6, install the upper sliding beam and lower slider beam of every group of smoothing roll
Between be respectively equipped with 2 locked hydraulic cylinders and 2 auxiliary hydraulic cylinders.
Cross-roll straightening machine of the present utility model increased hydraulic lock clamp force, which be greatly improved by increasing auxiliary hydraulic cylinder
During aligning steel pipe, the rigidity and stability of body, realizes good leveling effect, and the outer surface and precision for aligning steel pipe is carried significantly
It is high.
Description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cut away left side view of Fig. 1.
Specific embodiment
This utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
Cross-roll straightening machine as depicted in figs. 1 and 2, including it is upper spider 1, lower bearing bracket 6, upper sliding beam 7, lower slider beam 8, vertical
Post 3 and 3 groups of smoothing rolls, upper spider 1 and lower bearing bracket 6 are connected by 8 root posts 3, and upper spider 1 is provided with 3 pressure leading screws 12, pressure
Lower leading screw 12 is driven by motor 11, pressure leading screw 12 be connected with upper sliding beam 7 by feed screw nut, upper sliding beam 7 and downslide
The two ends of dynamic beam 8 are enclosed within column 3 by sliding sleeve 2 respectively, and the upper straightening roll 4 of 3 groups of smoothing rolls and lower smoothing roll 5 are separately mounted to
On upper sliding beam 7 and lower slider beam 8,6 locked hydraulic cylinders 9 and 6 auxiliary are installed between upper sliding beam 7 and lower slider beam 8
Hydraulic cylinder 10, is respectively equipped with 2 locked hydraulic cylinders 9 and 2 between the upper sliding beam 7 and lower slider beam 8 of installing every group of smoothing roll
Auxiliary hydraulic cylinder 10, upper sliding beam 7 are provided with.
Pressure leading screw 12 is driven by motor 11 and is rotated, and drives upper sliding beam 7 to transport about 3 along column by feed screw nut
It is dynamic, so as to drive upper straightening roll 4 to move up and down, the pressure of smoothing roll is realized, while locked hydraulic cylinder 9 and auxiliary hydraulic cylinder 10 are locked
Tightly, it is ensured that the rigidity and stability of straightener during aligning steel pipe.The quick opening that oil cylinder 13 can realize smoothing roll is opened soon, it is to avoid
Steel tube end part is bumped against with smoothing roll.
