It is transported to the cutting station for cutting through each transfer roller table, and the cut steel workpieces are transported to the next station.

Applicable workpiece materials: carbon structural steel, stainless steel.

Cutting method: plasma cutting

Types and sizes of cut pipes:

H-beam: 100-600mm

Angle steel/Channel steel: 100-400mm

Round pipe:60-600mm

Square tube: 100-400mm

Length: 12 meters

2. Description

The total length of the entire cutting unit is 15000mm, of which the length of the cutting station is 1000mm, and the conveying roller table in the feeding positioning and feeding area is 14000mm, which ensures that the maximum cut material 12000mm is accepted and the effective range of trolley positioning and feeding.

3.1 This production line cutting unit consists of a feeding and conveying cutting roller bed, a material feeding moving body, a cutting head rotating assembly, a workpiece output mechanism, a control system and software.

3.2 Feeding and Cutting Roller

The feeding and cutting roller bed receives raw materials, and cooperates with the clamping device and the mobile trolley to grab the materials to complete each positioning and cutting work.


Raw material clamping device

3.3 Cutting head rotating assembly

The plasma cutting head can effectively move 160mm in the radial direction of the pipe, which can meet the cutting requirements of all materials. Two sets of cylinders are used to position the steel workpiece to ensure the center of the steel workpiece, thereby improving the cutting accuracy of the workpiece.

3.4 Material feed moving body

The mounting surface of the feeding and cutting roller frame is processed by a gantry milling machine, and a precision linear guide is installed as the transmission part of the workpiece grabbing, feeding, positioning, and moving trolley. The driving part adopts Japan's Panasonic 1KW servo control to achieve accurate transportation.

3.5 Industrial Control System

The structure mode adopted by the control system: industrial control all-in-one machine + motion control card. The industrial computer is mainly used to establish a user interface and process and calculate the workpiece, send the generated result data to the motion control card, and turn it into an execution command to drive the movement of the control axis, and process a series of cutting process instructions at the same time, so as to implement cutting of workpieces.

The programming software is the main core of the control system. This case uses the Yomi nesting programming system as the main programming tool. The software uses AUTOCAD as the basic programming platform, with simple operation, intuitive graphics and rich functions, which can greatly improve the work efficiency.

3.6 Controlled axes

This cutting machine adopts 6-axis control mode.




Motor power


X axis

The axis along which the torch moves along the workpiece



Y axis

The axis that the torch rotates around the workpiece



Z axis

The axis that the torch moves up and down



U axis

The axis that the torch moves left and right along the workpiece



W axis

The center of the disc automatically locates the left and right axes



A axis

The center of the disc automatically locates the lifting axis


3.7 Intersection software (KASRY AutoPipe)

The software is mainly divided into two major modules: the basic library and the tube quilting frame module.

After summarizing various commonly used intersecting line types, the basic gallery is summarized into twelve basic intersecting line types, which are listed in the form of a gallery. Each standard diagram is divided into different conditions and usage states. Various forms are optional. When operating, you only need to select a standard graphic, and enter data in the corresponding parameter table according to the prompts, the solid 3D graphic will appear on the screen, and the cutting control can be started, and cutting can be performed.

The basic library based on the CAD environment makes the operation of the cutting machine very intuitive and simple, and because the functions of the basic library cover most of the application needs, the requirements for the operator of the machine are correspondingly reduced.

The tube quilting frame module is a high-end application of intersecting wire cutting. The software can automatically process the CAD three-dimensional pipe quilting frame graphics, separate each pipeline in the pipe quilting frame, classify them into labels, label names and various attributes, and automatically calculate the intersecting line data of the pipe ends of the quilting frame. , generate a tube quilting frame information database, make the production of the entire intersecting line enter the information management level, and provide basic information for the production management system of the enterprise.

To organize the production of intersecting lines, the software operates the generated database, calls out the relevant pipe fittings, and automatically nests the provided raw material pipes to generate a cutting program based on the raw material pipes, which can implement pipe fittings. intersecting line cutting.
