Metal cutting line, metal slitting line

The line for transverse plasma cutting of metal is a large plasma installation for automatic cutting of structural steel, stainless steel, and non-ferrous metals. They are produced in different types according to design, but they are based primarily on a portal mechanical design and a CNC (computer numerical control) system.

What nodes does the line consist of?

Equipment of this type provides maximum automation of the plasma cutting process. At the same time, they are quite easy to use when operating in automatic mode.

Structurally, the line for longitudinal-transverse plasma cutting of metal consists of the following units:

• power supply (PS);
• portal system;
• plasmatron;
• CNC system;
• Desktop.

Power supply

Serves to convert alternating current into direct current with a voltage from 200 to 400 V (depending on the model). It also supplies current and voltage to initiate the pilot and cutting arcs. The power source provides the ability to regulate the current strength, the value of which is selected taking into account the grade and thickness of the steel. It may have a constant current or steeply falling current-voltage characteristic.

Photo 2. Appearance of the power supply

Portal design

This system includes many moving components - a portal with guides for longitudinal movement, a mechanism for transverse movement of the plasma torch. The portal is driven by a rack and pinion drive, which ensures backlash-free movement. Machines are produced with several control methods - single drives, 2-drive systems, as well as stepper and servo motors.

Photo 3. Portal system without a coordinate table

The portal system can have a different number of coordinates for moving the plasmatron - X, Y and Z (for performing an oblique cut, which results in a chamfer). The number of plasma cutters also varies depending on production needs - usually no more than two are installed.

Plasma torch

It is a device for creating and stabilizing a plasma jet. It is connected to a power source and has a water cooling system for heat-loaded components (electrode and nozzle), which increases their service life.

CNC system

Numerical program control is a computerized system that allows you to automatically control the drives of a portal plasma installation.

Photo 5. Computerized numerical control system

Structurally, the CNC consists of the following hardware components:

• Operating console – for entering a special program for cutting and controlling equipment operating modes.
• Operator panel - for visual control of the process, the ability to make adjustments to the control program.
• Controller – to control the equipment of the longitudinal-transverse cutting installation.

The system design also includes ROM and RAM.

Coordinate table

Made in the form of a metal flooring, which is intended for placing processed metal products on it. Typically, a high-quality exhaust system is installed at the work site to remove combustion products from the room.

Another technical proposal for a longitudinal-transverse cutting line

Design features of the equipment

Installations for longitudinal-transverse cutting can be equipped with additional systems and functions. One of the main ones is automatic height control, which has 3 modes - one for burning and two for cutting. This function allows you to increase the service life of consumables and improve cutting quality.

The height at which the metal workpiece is pierced is considered one of the most important parameters for increasing the life of the nozzle and the quality of the cut. During operation, the system moves the plasma cutter down until it contacts the surface of the material, and then sets it at the desired height. After burning the metal with plasma, the controller moves the plasma torch closer to the processed metal.

Photo 7. Operation of an automatic longitudinal-transverse cutting line

With a small distance between the plasma cutter and the metal, the thermal load on consumables increases and the risk of collision with the part increases. Excessively high height has a negative impact on the quality of cutting - the width of the cut and the heat-affected zone increase, which leads to deformation of the workpiece. Therefore, it is important to choose the optimal value, and this task is best handled by an automatic height control system.

How the lines work

Slitting lines operate on the same principle as any other plasma machine. The technology consists of the formation of a directional plasma arc as a result of the flow of current from the cathode to the anode. The high-speed jet instantly heats the steel workpiece to its melting temperature and blows it out of the cutting zone.

The gantry system is driven by a controller, which is responsible for moving the technological equipment. To do this, the control program developed by the technologist is pre-loaded into the numerical control system. At the same time, the CNC can reproduce contours of any complexity.

Photo 8. The process of cutting blanks of complex configurations

Control programs are developed for cutting both single parts and batch sets of blanks of different shapes and sizes. Using special software on a computer, they are laid out on a sheet of metal of certain dimensions. This makes it possible to rationally use sheet metal and minimize the amount of waste.

Principles and advantages of longitudinal-transverse cutting of metal

The technology for cutting metal rolls consists of preliminary cutting the material into strips of the required length and then exposing the workpieces to electric current.

The metal is separated by melting by point heating of certain sections of the strips with current. The required power and current are determined based on the thickness of the workpiece and its physical and chemical properties, as well as the frequency of the supplied current.

We recommend articles on metalworking

• Steel grades: classification and interpretation
• Aluminum grades and areas of their application
• Defects in metal products: causes and search methods

The metal strip in the cutting area should be locally heated in order to reduce resistance during longitudinal cutting. The achieved effect is possible due to a decrease in the mechanical properties of the metal with increasing temperature. The longitudinal cutting line allows you to make the cut as smooth as possible, with smooth curves, while creating strips of smaller width.

Products produced by longitudinal-transverse cutting meet the standards for the production of bent profiles of welded pipes with straight seams. The technology of longitudinal cutting of rolled metal is also economically beneficial, since it eliminates the need for subsequent processing of manufactured metal strips.

Cross cutting of metal is similar to longitudinal cutting. Special disc shears are used to grip the sheet workpiece. They fix the metal sheet between the shafts, which is then cut. The sheet being cut is pressed by tension against the upper shaft. The upper and lower shafts are constantly moving during the cross cutting process, ensuring continuous feeding of sheets.

VT-metall offers services:

Metal loses its rigidity when exposed to high temperatures, so for cutting it is often preheated with an electric current, and instead of cutting discs, steel rollers with a high carbon content are used. This modification allows you to significantly improve the quality of cutting the material.

Pros and cons of installations

Increasing productivity without losing the quality of products, minimizing production costs are the goals that any enterprise pursues. Modern lines for longitudinal and transverse cutting of metal with a plasma arc are guaranteed to cope with these tasks.

Photo 9. The process of cutting a profile pipe

The equipment has a number of advantages:

• High cutting speed - depending on the model, thickness and grade of steel being cut, it can reach up to 7 m/minute.
• Increased accuracy - a technically sound machine cuts workpieces with a maximum error of up to 0.35 mm.
• Technological flexibility – the ability to cut blanks of any shape and size.
• The minimum level of deformation of cut parts, even when working with thin sheet steel, is ensured due to the directional effect of the plasma arc and a small heat-affected zone.
• High quality of cut - the edges are smooth, without slag, sagging and scale, which eliminates the need for additional processing before welding.

Line for longitudinal-transverse cutting of rolled metal “K-4PPR” - on request

Main characteristics

The operating parameters and functionality of the installations are determined by the rated power of the power source used and the presence of additional automation systems. The quality and accuracy of the cut depends on the numerical control system and the skill of the technologist who develops technological cutting maps for the control program. When working, you need to carefully consider the location of the workpieces on the sheet relative to each other, set the necessary allowances, where not only the width of the cut should be taken into account, but also arc fluctuations and other factors.

Photo 14. Cutting process with several plasma cutters

The main characteristics of automatic plasma cutting lines include:

• maximum cutting thickness;
• cutting speed;
• type of drive;
• geometric accuracy of cut workpieces;
• length of guides and distance between them;
• equipment width;
• vertical stroke of the cutter.

The main operating parameters of the cutting process itself are the current, which determines the thickness of the rolled metal being cut, the burning time, the cutting speed and the width of the cut.

It is possible to ensure a perfectly even cut without deformations, sagging and scale only if the current strength and the speed of longitudinal and transverse movement of the plasma torch during cutting are correctly adjusted. The nozzle must also match the operating characteristics of the process, since it is available with different exit cross-sections. Also, by replacing the nozzles, you can significantly expand the range of work performed for a single installation.

Where are they used?

The scope of application of longitudinal-transverse cutting lines is quite wide, since plasma machines are designed for cutting carbon (up to 100 mm thick), alloy steels (up to 50 mm), cast iron (up to 90 mm) and non-ferrous alloys based on copper (up to 80 mm) and aluminum (up to 120 mm).

Plasma cutting technology is used in the production of building metal structures, various elements of industrial and metallurgical equipment, parts of ships and aircraft, agricultural machinery, etc.

Automatic plasma cutting is actively used in many industries - the lion's share is occupied by heavy engineering, the construction industry, and metallurgy. The lines are also used in automobile, aircraft, shipbuilding, bridge construction and other fields of activity.
