Pipe Straightening Machine Pipe Straightener

I. Summery:
The equipment is used for straightening steel pipes with diameters ranging from 21 to 114.3mm and thicknesses ranging from 1.5 to 6.5mm. The equipment adopts the roller arrangement, the vertical six rollers are fully active, the straightening precision is high, and can meet the requirements of the relevant national standards on the tube shape and straightness of the steel pipe.

II. Technical Features:
Automatic adjustment mode: The equipment adopts automatic working mode. As long as the parameters of steel pipe diameter, wall thickness and material are input on the touch screen, the Angle of the roller and the position of the upper roll will automatically reach the position, and it can work directly without manual adjustment.

V,Specification introduce:
The equipment is composed of upper frame assembly, lower frame assembly, straightening roller assembly, column assembly, caruniversal shaft assembly, transmission device, base, electric control system and other parts.
The frame adopts welded box structure with good stiffness and compact structure.
The straightening roller is made of Cr12 alloy steel, which is surface quenched with high hardness and good wear resistance.
The transmission device adopts the non-standard cylindrical gear reducer, the gear adopts the hard tooth surface, the transmission precision is high, the service life is long, the two-speed motor drive, the motor adopts the domestic famous brand motor, the transmission is accurate. Speed control adopts imported frequency converter, which can adjust the speed according to different specifications.

VI,Straightener roller design features:
In order to ensure straight degrees and accuracy requirements, the design of the pore type of this machine adopts the design idea of "round-oval-circle". It uses high-intensity racks and high-intensity, high-hardness rollers to force the steel pipe to in the first pair of straight rollers of the first pair of straight rollers. Keep it under the middle of a pair of straight rollers in the middle, which changes from circular to oval; in the third -to -straight roller, the steel pipe is forced to turn into a round shape, which can completely eliminate the pipes in the forming and welding process of the pipes and welding process. The residual internal stress generated in the middle allows the steel pipes to not produce elastic deformation after the straight machine, which fundamentally eliminates the internal cause of bending, and ensures the accuracy of the straightness. The design of the straight roller is bilateral and the middle convex and concave roller body. This roller can ensure that the surface of the steel pipe after the correction does not produce any residual traces..

VII. Electronic control system:
Electrical system composition: 1 operating counter of electronic control cabinets
The main driver system uses AC frequency frequency control, and has no speed adjustment
The pulse encoder is used to measure the angle and position of the straight roller
The main control PLC and the touch screen use Siemens products, supporting Profinet

Optional:
Automatic control of adjustment for different diameter pipe:
Adjustment: Set the main parameters of the steel pipes on the touch screen, such as the diameter, wall thickness, and material. You can use the database to adjust the supporting straight parameter array (angle and pressure), and the straight roller can be automatically adjusted in place.
Data processing: Randomly provide a set of straight parameters; the experience parameters of the user's production process can be stored in the database for reference for future; the data preservation volume is 1,000 groups.
