The semi-automatic feeding mechanism can realize the semi-automatic feeding function of round, square and rectangular pipes, and the pipes need to be placed in the storage part manually.

Electrical control part

Laser pipe cutting machine electrical control system is to ensure that a variety of 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 high-performance CNC system, the system is based on windows operating platform, stable and reliable operation, containing 64-bit microprocessor; the system has a fast interpolation operation speed, easy operation, good dynamic performance, strong load capacity and other characteristics.

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 machine is stable, reliable and responsive in operation. The drive motor is AC servo motor, AC servo motor for driving the X-axis, Y-axis, AW (synchronous rotation) axis of the machine tool, characterized by good acceleration performance, fast response speed, W, Y-axis maximum positioning speed up to 100m/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 NC control.

Auxiliary peripheral equipment

Including water chiller, cold air system, exhaust system, etc.

Bed and auxiliary support part

The bed adopts stacked welded one-piece bed, which is treated by annealing to eliminate internal stress, and then finish machining after rough machining by vibration aging, thus greatly improving the rigidity and stability of the machine tool and ensuring the accuracy of the machine tool. The Y-axis rack and linear guide are made of high precision products, which effectively ensure the accuracy of transmission; both ends of the stroke are controlled by limit switches and are equipped with hard limit devices, which effectively ensure the safety of machine movement; the machine is equipped with automatic lubrication device, which adds lubricant to the moving parts of the bed at regular and quantitative intervals. The machine is equipped with automatic lubrication device to add 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.
The bed is equipped with reducer support mechanism, reducer support is mainly for cutting longer pipe (pipe diameter smaller pipe) excessive deformation of auxiliary control, by the cylinder control reducer cutting support of the pipe, when the rear chuck moves to the corresponding position, auxiliary support can be lowered to avoid, for different sizes of pipe please use the corresponding support radius to adapt to the height of the pipe.

X-axis side column and chuck part

The X-axis side column is welded with steel plate, annealed to eliminate internal stress, rough machining, vibration aging and then finishing to ensure the rigidity and stability of the moving parts of the laser head. The side column is fixed on the bed, equipped with high quality module, servo motor driven linear module, so that the Z-axis sliding plate to achieve reciprocating motion in the X direction. In the process of movement, the limit switch controls the travel to ensure the safety of system operation.
The chuck is divided into 2 pneumatic full stroke chucks, the rear chuck is movable (Y-axis) and the front chuck is fixed. The rear chuck is mounted on the bed for cutting and clamping the feeding material, and the front chuck is mounted on the end of the bed for clamping the material used. The front and rear chucks are driven by servo motor respectively, which can realize synchronous rotation.

Z-axis device

The 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 controlled by the servo motor controlled by the CNC system, which drives the linear module and drives the Z-axis slide plate up and down to complete the reciprocating movement. The upper and lower ends are controlled by proximity switches to ensure the safety and reliability of the movement. The linear modules are made of high quality products to ensure the accuracy of transmission.
The Z-axis can be used as a CNC axis for its individual interpolation motion, while it can be linked with X and Y axes, and can be switched to the follower control to meet the needs of different situations. Since the Z-axis follower is also controlled by the CNC system, the accuracy of the follower is high and the stability is good, thus ensuring the quality of the cut.
After the capacitive sensor in the Z-axis device detects the distance from the nozzle to the surface of the plate, the signal is fed back 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 cutting head can adjust the focus automatically or manually, and the position of the focus can be adjusted according to the material and thickness of the cutting material, thus obtaining a good cutting section.

Front pick-up device

The front pick-up device includes 2 sets of cylinder-controlled support mechanisms to hold the pipe when it is cut long and to prevent it from sagging.
When the workpiece is cut, the cut scrap falls to the scrap trolley and continues to cut the workpiece. When the cut workpiece goes to the corresponding down feed auxiliary support position, the auxiliary support device in the corresponding position is raised under the push of the cylinder to hold up the cut workpiece, and when the length of the cut workpiece is extended to the next set of auxiliary support, the next set of auxiliary support is raised instantly, and when the workpiece is finished cutting, the raised auxiliary support cylinders are all retracted, and The workpiece falls to the drop plate and slides down to the storage place. The cylinder action is controlled automatically by the system.

Electrical control system

M2 series CNC laser pipe cutting machine electrical control system mainly consists of the
Low voltage electrical system. The laser cutting machine is equipped with high performance Pachu CNC system, which is a WINDOWS-based PC CNC system with fast interpolation and easy operation; the servo system is a servo motor and driver, which is stable and reliable, with good dynamic performance, strong load carrying capacity and easy operation. The machine operation soft keys can have different functions in different operation modes, thus reducing the operation buttons and simplifying the operation panel. The operation functions are displayed by menus in various modes, making the operation intuitive.
