Abstract
The utility model relates to a square pipe straightening machine set used for straightening plastic deformation square pipes after high temperature annealing. The utility model is characterized in that the square pipe straightening machine set comprises a base (1), wherein a plurality of main racks (2) and a plurality of assistant racks (3) are arranged on the base (1), and the main racks (2) and the assistant racks (3) are arranged at intervals; upper rolls (2.1) are arranged on the main racks (2), and lower rolls (3.1) are arranged on the assistant racks (3); and two left-and-right symmetrical side racks (4) are arranged between two adjacent main racks (2) respectively, and left rolls (4.1) and right rolls (4.2) are arranged on the side racks (4) at intervals. In the square pipe straightening machine set, the upper rolls, the lower rolls, the left rolls and the right rolls are arranged at intervals, so as to ensure that the square pipes can not be deformed under very heavy pressure in straightening, so that the straightening effect is good, and the quality of the square pipes are guaranteed.
Description
Technical field
The utility model relates to a kind of square tube aligning unit, is used for the square tube that produces plastic deformation behind the high annealing is aligned.
Background technology
Square tube need be passed through high annealing in process of production, can produce plastic deformation after square tube is annealed, therefore the square tube of distortion need be put into the aligning unit and align.The top roll of aligning unit in the past and lower roll are for being symmetrical arranged up and down, and left roller and right roller are for being symmetrical set.The aligning unit is when aligning the square tube of high temperature, top roll and lower roll pressurize up and down to the same part of square tube, and left roller and right roller pressurize about the same part to square tube simultaneously, are easy to square tube is depressed into distortion, cause its leveling effect relatively poor, thereby influenced the quality of square tube.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of leveling effect better, can guarantee the square tube aligning unit of square tube quality.
The purpose of this utility model is achieved in that
A kind of square tube aligning unit, comprise base, described base is provided with several host frame and some secondary frames, described mainframe and secondary bay interval setting, described mainframe is provided with top roll, described secondary frame is provided with lower roll, is provided with two symmetrical side frames between described adjacent two mainframes, is arranged at intervals with left roller and right roller on the described side frame.
The beneficial effect that the utlity model has is:
The utility model square tube aligning unit is by with top roll and lower roll, and left roller and right roller change at interval and being provided with, and guaranteed that square tube can not be subjected to bigger pressure and cause distortion when aligning, makes that its leveling effect is better, and has guaranteed the quality of square tube.
Description of drawings
Fig. 1 is the structural representation of the utility model square tube aligning unit.
Fig. 2 is the vertical view of Fig. 1.
Fig. 3 is the left view of Fig. 1.
Wherein: base 1, mainframe 2, top roll 2.1, secondary frame 3, lower roll 3.1, side frame 4, left roller 4.1, right roller 4.2.
The specific embodiment
As Fig. 1 to Fig. 3, the utility model relates to a kind of square tube aligning unit, comprise base 1, described base 1 is provided with several host frame 2 and some secondary frames 3, described mainframe 2 and secondary frame 3 are provided with at interval, and described mainframe 2 is provided with top roll 2.1, and described secondary frame 3 is provided with lower roll 3.1, be provided with two symmetrical side frames 4 between described adjacent two mainframes 2, be arranged at intervals with left roller 4.1 and right roller 4.2 on the described side frame 4.
The utility model square tube aligning unit passes through top roll 2.1 and lower roll 3.1, and left roller 4.1 and right roller 4.2 are to be provided with at interval, guaranteed that square tube can not be subjected to bigger pressure and cause distortion when aligning, make that its leveling effect is better, and guaranteed the quality of square tube.
