Background
With the increasing replacement of plasma equipment by high-power flatbed cutting machines in recent years, the demand for high-power and high-speed cutting of medium and thick plates has also emerged. At the same time, in the sub-sectors such as engineering machinery, boilers, agricultural machinery, etc., the demand for high-speed cutting of large-format medium and thick plates with large contours and high-speed cutting of small parts of large-format plates is more obvious.
The large-format laser cutting equipment on the market is still at the stage where laser cutting devices replace cutting devices. For example, the picture on the right ( HSG product from a friendly company) aims to sell laser equipment at a low price. However, it does not really have the characteristics of laser high-speed / high-precision cutting ( 0.5G , 60m/min movement speed, non-processing speed, positioning accuracy is 0.1/m , and the error of the entire length of the equipment is more than 0.5 ), and cannot achieve efficient output.
Therefore, the demand for a local high-acceleration large-format laser tube cutting machine is imminent.
Main indicators
It realizes large-format four-axis and can realize automatic recognition (CAM) cutting in three scenarios.
Scene 1: Small contour intensive cutting within the range of 3X1.25 meters, cut by X, Y2, and Z axes in the beam;
Scene 2: Simple contours larger than 3X1.25 meters, cut by X, Y1, and Z axes;
Scene 3: Complex contours larger than 3X1.25 meters, cut by X, Y1/Y2 (compound motion), and Z axes;
Realize the standardized and modular design of series products;
X-axis motion parameters: 1.5g/110m/min;
Y2-axis motion parameters: 1.5g/110m/min;
Z-axis motion parameters: 1.5g/50m/min;
Y1-axis motion parameters: 0.6g/60m/min
Mechanical details
The whole machine is equipped with a sheet metal protective cover and an observation window ( OD6+ ) to better protect the operator when using or observing the equipment status.
Among them:
A. The right side upper liftgate (supported by gas spring) is convenient for maintenance.
B. The left sliding door is convenient for observing and replacing the nozzle and protective lens.
C. A dedicated wide-angle camera is installed inside the equipment to observe the real-time status of the equipment cutting process;
The bed structure adopts a plate-welded box-type frame structure, with reasonable arrangement of rib plates and plug-in structure at key connection points. Under the premise of maximum strength use, the laser burning area is reduced to avoid thermal deformation of the bed.
At the same time, strict welding process is formulated, and annealing and stress relief treatment are carried out to ensure the stability of the bed.
The crossbeam is made of steel crossbeam + aviation-grade high-strength aluminum alloy, and the steel crossbeam adopts a plug-in structure. Strict welding process is formulated, and annealing and stress relief treatment are performed to ensure the stability of the crossbeam.
The middle extruded aluminum profile structure adopts an outer square and inner circle + cross-partitioned composite structure . While being lightweight, each stress-bearing surface is individually provided with reinforcing ribs to extremely enhance the dynamic response of movement .
The equipment is equipped with two operating stations and displays :
A. One is on the removable protective cover, which allows the operator to observe the actual cutting of the workpiece while operating the equipment.
B. The other one is on the front side of the equipment, which can reduce the operator’s moving distance and reduce the work intensity. Customers can freely choose according to the usage scenario , which is convenient for customers to use.
C. The two operating devices are interlocked. If one is operated, the other cannot be operated, ensuring safe operation of the equipment.
Dust extraction system inside sheet metal hood
The cutting area is equipped with a protective cover to effectively limit the damage to the human body caused by laser beams, cutting smoke, etc.
The equipment is equipped with a cross-flow fan design to ensure timely collection of smoke and dust. A special smoke integrator is installed on the rear side to effectively collect the internal smoke and heat .
Design of exhausr system:
The size of the partition dust removal opening is 120*400mm , and the ventilation area could increase 30% ;
Replace the flap valve with a partition-free design, which greatly reduces the wind resistance coefficient;
The equipment is set with cross partitions in front, back, left and right, which can realize zoned dust removal and effectively utilize the capacity of the smoke dust collector;
Y- shaped galvanized air duct is installed on the rear side of the bed , and the air duct outlet is set on the rear side of the bed to facilitate on-site installation .
Safty configuration
The front / side of the front bed is equipped with pedals to facilitate loading and unloading easily;
Two sets of safety light curtains are installed in front and back of the sheet metal shield to prevent collisions when users are unloading materials at the same time;
A separate camera is installed on the rear side of the sheet metal, which is convenient for observing the equipment status while operating the equipment;
The equipment is equipped with at least 3 emergency stop switches, on the left side + right side of the sheet metal protection + movable operating table;
Optical fiber plug-free design.
Selection of equipment anti-burning materials
A. The main body of the bed is paved with cast iron plates, which are resistant to burning and heat insulation and convenient for users to clean slag;
B. The work surface is equipped with a graphite plate, which can effectively prevent the laser from burning and thermal deformation of the surface;
C. The scrap car is paved with high-alumina refractory bricks, which can effectively prevent the laser from burning and thermal deformation of the scrap car;
