Steel straightening machine performance and principles

Construction or industrial road traction is generally reinforced by former or wire straightening machine, mainly for steel pre-cut path to improve the surface quality. Then the leveler, the front wheel straightener pre-deformation, then spun the cylinder, he is a key component, the speed is about 1500r / min (16mm wire below), there are 5-6 deformed wheel spun by High-speed rotating cylinder to achieve the purpose of straightening wire, steel wire, after straightening out again by round deformation, stable wire straightness.

Leveler came out from behind the wire is fixed-length cut, there are two structures, in the case of construction steel, hydraulic cutting blade is generally straight, in the case of industrial steel, is generally semi-circular blade, mechanical cutting. The use of this leveler leveler for straighteningφ133 ~φ385 metal pipe.

Working principle and structure characteristics

1. The main components of the straightening machine include: the rack assembly, the lower chassis assembly, columns, roller assembly, the lower roll assembly, assembly and the relationship of each part reducer, see leveler total figure.

2. The roller straightening machine for six vertical pipe ramp roller leveler rolls arranged 2-2-2 type. Straightening roller is driven, the roller is divided into two six-row cross inclined, i.e., with the center line of the pipe straightening principle angled above three rollers, the following three rollers. Straightening rollers were down by two AC motors JZR263-10 metallurgy ratio of 0.7 to 5.7 after the auto transmission, through the universal joint, drive throat diameter of 400mm straightening roller rotary motion. When bitten into the pipe while rotating and movement forward will form repeatedly deformed so as to achieve the purpose of the pipe to be straightened. The upper and lower frame straightening machine for welding parts, linked by six pillars, which constitute the column frame structure, are relatively easy to observe and adjust. Straightening rollers were content with the roller base, and then screwed into the carriage up and down the frame, according to the diameter of the pipe straightening roller changes the angle. Loosen the bolts to adjust, adjust after locking fastening. Three straightening rollers were on the rack by a 3KW AC motor worm gear 46 (device) drive screw driven carriage T180x8 do move up and down through the speed ratio. By the middle of the frame straightening roller using shims to adjust the form of moving up and down the slide. This structure is easy to maintain, easy to adjust.
