Abstract
The effective high-accuracy straightening machine of a kind of square-outside and round-inside, comprise and be arranged at entablature in frame and sill, be provided with in horizontally disposed upper straightening roll group between upper and lower crossbeam and lower smoothing roll group, wherein: described lower smoothing roll group is provided with the power-driven mechanism that each smoothing roll is rotated, described upper straightening roll group is provided with the electronic screw mandrel screw-down of adjusted in concert smoothing roll height, above-mentioned each smoothing roll adopts V-type roll shape, arranges between described upper and lower smoothing roll in dislocation.Owing to have employed the roll shape structure of each smoothing roll V-type and being the layout misplaced up and down between smoothing roll, while guarantee square-outside and round-inside tubing four faces, four knuckle lines once obtain aligning, also ensure that aligning after square-outside and round-inside tubing along length, wall thickness, hole size all regulation the margin of tolerance in, ensure that the quality of product, improve production efficiency.
Description
Technical field
The utility model relates to a kind of metal pipe material manufacturing equipment, the tube straightener for pipe that particularly a kind of square-outside and round-inside is effective.
Background technology
Traditional rectangular tube bar straightener generally adopts horizontal roller system or vertical roller system or combines roller system straightener, and smoothing roll is cylindrical.Due to the randomness of rectangular tube bar stock bent, when adopting horizontal roller system or the vertical roller system straightener aligning of cylindrical roller, a passage can only align two faces of rectangular tube bar, must turn over afterwards and turn 90 degrees, align two other face of rectangular tube bar by a passage again, namely at least need two passages just can complete aligning to a rectangular tube bar.If rectangular tube bar exists twisted phenomena, then need could be corrected by a lot of passage, so aligning efficiency is very low, the precision after aligning is also undesirable; When adopting the combination roller system aligning of cylinder roll shape, compared with horizontal roller system or vertical roller system straightener, flattening precision can be improved, reduce aligning passage, but combination roller system straightener is in order to aim at pass, in usual two roller systems, has at least an energy to move left and right along aligning center line, and another can move up and down, therefore cause equipment huger, complex structure, cost is higher.
Utility model content
Technical problem to be solved in the utility model is, for the deficiency of above-mentioned existence, provides a kind of and realizes a passage to the aligning of the horizontal and vertical bending of pipe fitting, can eliminate again the effective high-accuracy straightening machine of square-outside and round-inside that pipe fitting torsional deflection is bending simultaneously.
The technical solution of the utility model is: the effective high-accuracy straightening machine of a kind of square-outside and round-inside, comprise and be arranged at entablature in frame and sill, be provided with in horizontally disposed upper straightening roll group between upper and lower crossbeam and lower smoothing roll group, wherein: described lower smoothing roll group is provided with the power-driven mechanism that each smoothing roll is rotated, described upper straightening roll group is provided with the electronic screw mandrel screw-down of adjusted in concert smoothing roll height, above-mentioned each smoothing roll adopts V-type roll shape, arranges between described upper and lower smoothing roll in dislocation.
The utility model is owing to have employed the roll shape structure of each smoothing roll V-type and being the layout misplaced up and down between smoothing roll, while guarantee square-outside and round-inside tubing four faces, four knuckle lines once obtain aligning, also ensure that aligning after square-outside and round-inside tubing along length, wall thickness, hole size all regulation the margin of tolerance in, ensure that the quality of product, improve production efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model;
Fig. 3 is the A-A sectional view of the utility model Fig. 1.
Detailed description of the invention
The utility model as shown in Figure 1, Figure 2 and Figure 3, the effective high-accuracy straightening machine of a kind of square-outside and round-inside, comprise and be arranged at entablature 1 in frame and sill 2, be provided with between upper and lower crossbeam 1,2 in horizontally disposed upper straightening roll group 3 and lower smoothing roll group 4, wherein: described lower smoothing roll group 4 is provided with the power-driven mechanism 5 that each smoothing roll is rotated, described upper straightening roll group 3 is provided with the electronic screw mandrel screw-down 6 of adjusted in concert smoothing roll height, above-mentioned each smoothing roll adopts V-type roll shape, arranges between described upper and lower smoothing roll in dislocation.
The roller number of above-mentioned upper straightening roll group 3 is 7, and the roller number of above-mentioned lower smoothing roll group 4 is 6.The governor motion 7 can eliminating screw mandrel gap in electronic screw mandrel screw-down 6 is provided with between entablature 1 and upper straightening roll group 3.Above-mentioned governor motion 7 comprises, and is installed on the Rectangular Spring 71 in entablature 1 for a pair, and described Rectangular Spring 71 is connected with the connecting plate 73 of upper straightening roll respectively by a pull bar 72.The setting of above-mentioned governor motion, the elastic force by a pair Rectangular Spring makes the screw mandrel gap in screw mandrel screw-down 6 remain certain value, thus further ensures the precision of square tube aligning.
