Auxiliary peripheral equipment

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

Bed and auxiliary support part

The bed adopts side-hanging structure and stacked welded one-piece bed, which is treated by annealing to eliminate internal stress, and then finish machining after rough machining with 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 the transmission; both ends of the stroke are controlled by limit switches and equipped with hard limit devices, which effectively ensure the safety of the 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.
There are 3 groups of follow-along support mechanism on the bed, each group of support is controlled by independent servo motor to lift, mainly to follow-along with the excessive deformation of cutting longer pipe (pipe with smaller diameter). When the rear chuck moves to the corresponding position, the auxiliary supports can be lowered for avoidance.

X-axis device and chuck part

The cross beam of X-axis device adopts gantry type structure, which is made of square tube and steel plate combination welded, 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 gantry components are fixed on the bed, and the X-axis adopts servo motor-driven linear module drive to realize the reciprocating motion of the slide in X direction. In the process of movement, the limit switch controls the stroke for limit to ensure the safety of system operation.
The chuck is divided into 2 pneumatic full-stroke chucks, front and rear, both of which can move in Y direction. The rear chuck is responsible for clamping the feeding pipe, and the front chuck is installed at the end of the bed for clamping the material used. The front and rear chucks are driven by servo motor respectively, which can achieve synchronous rotation.
With the double chucks clamping together, short tail material can be cut and the last workpiece needs to be picked up manually.

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 CNC system with a servo motor, which drives the linear module and drives the Z-axis slide plate to reciprocate up and down to complete the 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 consists of a cylinder-controlled support plate to hold the pipe when it is cut long and to prevent it from sagging.
When the workpiece is being cut, the lifting support cylinder holds the support plate to support the pipe and prevent it from sagging. When the workpiece is finished cutting, the rising support cylinder retracts completely and the workpiece falls onto the drop plate and slides down to the material storage area. The cylinder action is automatically controlled by the system.

Chain type semi-automatic feeding device

Standardly equipped with 3 groups of chain feeding devices, which can realize semi-automatic feeding of round pipe, square pipe, rectangular pipe and profile, and need manual swinging of material.

Electrical control system

T1 series CNC laser pipe cutting machine electrical control system is mainly composed of Patrons CNC system, servo system and low voltage electrical system. This laser cutting machine is equipped with high performance Pakchu CNC system, which is a WINDOWS-based PC CNC system with the characteristics of fast interpolation operation and convenient operation; the servo system is a servo motor and driver, which is stable and reliable, with good dynamic performance, strong ability to carry load and convenient 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 ways, making the operation intuitive.
