[Product introduction]

32 tube welding machine Introduction

Frequency welded pipe production line is mainly used for continuous production of longitudinally welded pipes, high frequency induction welding tube can produce, but also the production does not exceed the tube machining range square tube and Yixingguan of;

Production: raw materials - decoiler → → shear welder → material storage device molding sizing machine → flythe Saw → balers and auxiliary roller table bench, electrical control systems, high-frequency welding equipment, raw materials for low-carbon steel, low alloy steel strip

The main technical parameters

Unit rolling bottom line elevation: 800mm
Finished pipe OD: φ32mm minimum: φ12mm
Thickness: 2.25mm Minimum: 0.5mm
Forming Speed: 20 ~ 100m/min
Motor a 55kW
100kW high-frequency welding machine

Structure description

The feeding agencies: vertical roller guide and five roll flattening mechanism to ensure the smooth entry into the width of the strip by the flattening molding;

The flat roller rack: rack for overall finishing, flat roll, flat roll axis level adjustment

Vertical roller rack: vertical roller racks and vertical roller slider as with grinding assembly, vertical roll in the vertical roll axis can be up or down to fine-tuning

Extrusion roller frame: steel pipe welding forming key equipment manufacturing precision directly affect the quality of welding

Gearbox: gear spiral bevel gears, material 20CrMnTi, high strength, stable and reliable, long life;

Molding, sizing, soldering, cooling, transmission to the overall structure of the double table, help to improve the precision equipment, while ease of installation and commissioning.

Q: A roll forming machine, rolling out of the length is always not up to a fixed size, not too small, that is, more than that, what is the cause?: Maybe there is something wrong with that roller. It rolls out of the wrong angle and the size will be out of order.

Q: What is rolling forming processing?: Ironing the surface of the workpiece with a raised micro wave crest to fill the concave micro troughs, thus changing the distribution of the peaks on the surface, and obtaining smaller surface roughness values.

Q: Improvement in rolling forming process: Can not meet the slender rod, thin-walled tubes and other rigid parts of the processing.

Q: Introduction of roll forming process: With the progress of technology and the development of production, more and more attention has been paid to the roll forming process.

Q: What kind of material and what heat treatment are used for pressing roller (molding, feeding, cutting force, heavy load, heavy load) of sheet steel rolling machine?: Use 40Cr or 20Cr, Cr12.Cr12MoV, quenching and tempering treatment, think of hardness, high point, carburizing, nitriding, and consider adding lubrication device to extend its service life

Q: What is the surface rolling forming machine process?: Due to the rolling surface of metal plastic deformation, so that the surface microstructure of cold hardening and grain refinement, forming a dense fibrous, and the formation of residual stress, hardness and strength, so as to improve the surface wear resistance, corrosion resistance and compliance.

Q: Process mould for rolling forming process: A movable wire plate, made of the same fixed wire plate, for relative reciprocating motion. Roll forming is the design of different structures on the plate rolling on the workpiece. Roll out all kinds of thread, convex ring, knurling, end chamfering, groove with different width and thickness as well as other required shapes.

Q: Material and equipment for roll forming process: The most common type of roll forming is reciprocating flat wire twisting machine. Therefore, for the manufacturers of cold heading machines and screw rolling mills, the design of rolling dies is only a matter of design.
