Electrical control part

Laser pipe cutting machine electrical control system is to ensure that the various graphics running trajectory of an important part of the general electrical control system is mainly composed of CNC system and low-voltage electrical system.
The machine tool CNC system configuration Bertru high-performance bus type 5000A CNC system, the system is based on windows operating platform, stable and reliable operation, containing 32-bit microprocessor, with nesting software.

Low voltage electrical system

The low-voltage electrical system is located in the electric control cabinet, which is the interface part of the electrical control of the whole machine. All the original components of the electrical system are made by famous manufacturers at home and abroad to ensure that the whole machine is stable, reliable and responsive in operation. The drive motor is AC servo motor, AC servo motor is used to drive the X-axis, Y-axis, AW (synchronous rotation) axis of the machine tool, characterized by good acceleration performance, fast response speed, X,Y-axis maximum positioning speed up to 75m/min; machine tool Z-axis for the feed axis, using AC servo motor (with holding brake) for driving: that is, Z-axis cutting head, characterized by good dynamic response characteristics, both with the control and can be NC control.

The fiber laser

The fiber laser used has higher photoelectric conversion efficiency, lower power consumption and better beam quality compared to traditional lasers. The laser is compact, maintenance-free operation and ready for use. Due to its flexible laser output method, it can be easily integrated with system equipment.
2.5 Auxiliary peripherals
Including water chiller, exhaust system, etc.

Bed and follower support part

The bed is made of rectangular tube, which is annealed to eliminate internal stress, and finished by vibration aging after rough machining, thus greatly improving the rigidity and stability of the machine, and ensuring the accuracy of the machine. The machine is equipped with automatic lubrication device, which adds lubricating oil to the moving parts of the bed regularly and quantitatively to ensure that the moving parts operate in good condition, which can improve the service life of guide rails, gears and rack.
There are 3 groups of follower support mechanism on the bed, the auxiliary support is mainly to assist in controlling the excessive deformation of cutting longer pipes (pipes with smaller diameter), the servo motor drives the up and down movement of the pallet assembly, for rectangular pipes, the system will adjust the pallet height of the pallet assembly in real time according to the outer contour of the pipe to ensure that the pallet supports the pipe stably. When the chuck moves to the corresponding position, the auxiliary support automatically drops for avoidance.

X-axis, Z-axis, side column and chuck section

The side column is fixed on the bed, welded by steel plate as a whole, annealed to eliminate internal stress, rough machining, vibration aging and then finish machining to ensure the rigidity and stability of the moving parts of the laser head.
The X-axis guide adopts servo motor driven gear drive and high quality linear guide to make the Z-axis slide achieve reciprocating motion in X direction. In the process of movement, the limit switch controls the stroke to limit, and at the same time there are elastic cushion mechanical limits at both ends to ensure the safety of the system operation.
Z-axis device is mainly to realize the up and down movement of the laser head. The up and down movement of the laser head is done by the CNC control servo motor driving the linear module to drive the up and down reciprocating movement of the laser head. The upper and lower ends are controlled by proximity switches to ensure the safety and reliability of the movement. The linear modules are all made of high quality products to ensure the accuracy of transmission.
The capacitive sensor in the Z-axis device detects the distance from the nozzle to the surface of the plate and then feeds the signal to the control system, and then the control system controls the Z-axis motor to drive the cutting head up and down, thus controlling the constant distance between the nozzle and the plate and effectively ensuring the cutting quality. The position of the focal point is adjusted according to the material and thickness of the cutting material, thus obtaining a good cutting section. So Z-axis can be used as a CNC axis for interpolation movement with X, Y and W axes, and it can also be switched to follower control to meet the needs of different situations. Since the Z-axis follower is also controlled by the CNC system, the follower has high precision and good stability, thus ensuring the quality of cutting.
Depending on the laser head model, the laser head can be adjusted the focus automatically or manually.

Chuck

The chucks are divided into 3 groups of pneumatic chucks: front, middle and rear, with symmetrical design of rear and front chucks. 3 groups of chucks are driven by servo motors, all of which can move and rotate synchronously in Y-axis direction. Under the logic action set by the system, it can realize the pulling type cutting of the pipe, which can greatly improve the cutting accuracy and can conditionally realize the zero tail material cutting (depending on the workpiece cutting size and specific cutting process).
The Y-axis movement drive rack, linear guide, and W-rotation drive gear are all high precision products, which effectively ensure the accuracy of transmission; each group of chucks is controlled by limit switch and equipped with hard limit device, which effectively ensure the safety of machine movement.

Front pick-up

There are 2 groups of follow-me front pick-up devices. When the cut pipe is long, the plate will hold the pipe to prevent it from sagging. For rectangular pipe, the system will automatically calculate and adjust the height of the splice plate in real time according to the outer contour of the pipe to ensure that the splice plate supports the pipe stably.
According to the length of the workpiece, the system will automatically control the receiving action of 2 groups of receiving devices, i.e. synchronous lifting and turning, and only one of the components can be used for independent action, and the receiving plate can be automatically turned over for unloading, and the position of the lower feed opening can also be used to achieve waste screening, making the machine more intelligent, convenient and efficient.

Electrical control system

FLT-H1 three-chuck pipe cutting machine electrical control system is mainly composed of the bus type system, servo system and low voltage electrical system.
