The main composition of the product

The main components of JQ-25120HP series exchange platform laser plate cutting machine are: machine tool host, appearance protection system, control system, laser, water cooler, extractor fan, etc.

Machine tool host part

The host part of the machine is the main component of the whole exchange platform laser cutting machine, the cutting function and cutting accuracy of the exchange platform laser cutting machine are realized by the host part, the host part is composed of plate welding bed, machine plus beam and Z-axis device, funnel drawer, exchange platform, auxiliary system (lubrication, air and water), operating table and other parts.

Electrical control part

Exchange platform laser cutting board machine electrical control system is to ensure that the various graphics running track 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 machine tool X axis, Y axis, characterized by good acceleration performance, fast response speed, X,Y axis maximum positioning speed up to 140m/min; machine tool Z axis for the feed axis, using AC servo motor (with holding brake) drive: 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 part

The bed is welded as a whole, treated by annealing to eliminate internal stress, and finished by vibration aging after rough machining, 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; the limit switches at both ends of the stroke are controlled, and the machine is equipped with a hard limit device, which effectively ensures the safety of the machine movement; the machine is equipped with an automatic lubrication device, which can be used at regular intervals. The machine is equipped with automatic lubrication device, which can add lubricating oil to the moving parts of the bed at regular intervals to ensure that the moving parts operate in good condition, which can improve the service life of guide rails, gears and rack.

X-axis machine beam and Z-axis device

X-axis machine beam is roughly machined and then vibration-aged for finishing to ensure the rigidity and stability of the moving parts of the laser head. The bed is equipped with high quality linear guide rail, driven by servo motor, and the Z-axis slide plate is driven by high quality rack and pinion to 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
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 of the CNC system, and the motor drives the module to drive the Z-axis slide plate up and down reciprocating movement to complete. The upper and lower ends are controlled by proximity switches to ensure the safety and reliability of the movement. The guide rails are all made of high quality products to ensure the accuracy of the 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 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 cutting.
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.

Exchange platform

The exchange platform is mainly composed of support frame, knife strip frame, sprocket chain, etc. The horizontal movement of the upper and lower knife strip frames connected by the chain is mainly driven by the rotation of the sprocket, and there are rollers installed on the knife strip frame, which can ensure the smooth movement of the knife strip frame. The front and rear two platforms are exchanged quickly and in parallel, which greatly reduces the time used for loading and unloading and improves the processing efficiency There are many rows of knife strips on the knife strip frame, which carries the flat plate.

Electrical control system

JQ-25120HP series exchange platform laser plate cutting machine electrical control system is mainly composed of Pakchu CNC system, servo system and
Low voltage electrical system. The laser cutting machine is equipped with high performance Pakchu CNC system, which is a WINDOWS-based PC CNC system with fast interpolation and convenient operation; the servo system is imported AC servo motor and driver, which is stable and reliable, with good dynamic performance, strong load carrying capacity 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.
