What materials can the laser cutting machine cut?


Fiber laser cutting machine has the characteristics of wide cutting range, fast cutting speed, good cutting effect and maintenance-free, and is widely used. Especially for the cutting of sheet metal materials, fiber laser cutting machine has more advantages. Commonly used processing materials are stainless steel, carbon steel, aluminum, copper, titanium, etc.

Advantages of laser cutting machine processing


1. High precision: traditional pipe fittings are disconnected by hand, so each disconnected part is different. Laser production and processing uses the same set of tooling and fixture system software, which is produced and formulated by numerical control programming software, and produces and processes step by step at a time, with high precision. In modern manufacturing, precision is particularly important, laser production and forming to make each component have the same size.
2, high speed: laser cutting machine manufacturers said that the laser can be from a minute laser cutting dozens of meters of pipe fittings, hundreds of times the traditional manual method, which means that the laser production and processing speed is quite fast.
3. Coordination ability: Laser can produce and process irregular shapes easily, which is a complicated design for design scheme staff. However, this is unimaginable under the previous production and processing methods.

Advantages of plate laser cutting machine


The advantage of the plate laser cutting machine is high efficiency. Due to the transmission characteristics of the laser, the laser cutting machine is generally equipped with multiple CNC worktables, and the entire cutting process can be achieved through CNC. When operating, you only need to change the numerical control program, so it can be applied to cut parts of various shapes at this time, which can perform two-dimensional cutting and remove three-dimensional cutting. You will find it soon. The 1000W power laser cuts 2mm thick low carbon steel plate, and the cutting speed can reach 600 cm/min; the plate laser cutting machine does not need to clamp and fix the material when cutting. When the cutting quality is good, the incision is thin and narrow, the two sides of the incision are parallel and perpendicular to the surface, and the dimensional accuracy of the cutting piece can reach ± 0.05mm. The cutting surface is beautiful, and the surface roughness is only a few thousand microns. Even laser cutting can be used as a process without mechanical processing, and the parts can be used directly. Now, after the material is cut by laser, the width of the heat affected zone is very small, the performance of the material near the kerf is almost unaffected, the deformation of the workpiece is small, the cutting accuracy is high, and the geometry is high. The cross-sectional shape of the cut well of the plate laser cutter appears as a more regular rectangle.

Maintenance method of plate laser cutting machine?


What the plate laser cutting machine should do during maintenance is to change the water and clean the water tank. Before the machine works, please make sure that the laser tube is filled with circulating water. The water quality and the temperature of the circulating water directly affect the service life of the laser tube. It is recommended to use pure water, control the water temperature below 35 ℃, replace the circulating water above 35 ℃, or add ice to reduce the water temperature and add water. The next step is to turn off the power, unplug the water inlet hose, let the laser tube automatically enter the water tank, open the water tank, draw out the water, and clear the dirt on the water pump. Clean the water tank, replace the circulating water, put the water pump back into the water tank, insert the connecting pipe into the water inlet of the water pump, and arrange the joint. Use pump power alone and run for 2-3 minutes. Then there is the cleanliness of the fan of the plate laser cutting machine, especially after long-term use, it will cause a large amount of solid dust to accumulate inside the fan, and it will also cause the fan to make a lot of noise, which is not conducive to exhaust deodorization. When the fan with insufficient suction does not emit smoke smoothly, the power supply should be turned off first, the fan should be discharged into the air duct and air duct, the dust inside should be cleaned, then the fan should be installed and the air duct inside should be removed. Until the blades are clean, then install the fan. Then the plate laser cutting machine can support the carbon dioxide laser machine to work normally.

The difference between CNC plasma cutting machine and flame cutting machine, how to select?


The thermal deformation of workpieces with a thickness of 0.1mm-5mm is relatively severe, so it is necessary to consider purchasing a numerical control cutting machine with a 60 amp machine plasma power supply at this time. What is its cutting range: numerical control plasma cutting machine can be mainly used for non-ferrous metals (such as stainless steel, copper, aluminum, etc.) that cannot be cut by ordinary carbon steel plates and flame cutting machines, mainly because numerical control flame cutting cannot oxidize non-ferrous metal surfaces, it is also impossible to complete the cutting, but the groove of plasma when cutting thin plates is not obvious (e.g. workpieces below 5mm), so the thicker the workpiece, the larger the groove. This is related to the selection and matching of plasma power supply (domestic plasma power supply is different from imported plasma power supply, common machine plasma power supply is different from fine plasma power supply), and slag hanging and burrs are also different.

How do we improve the cutting accuracy of the CNC flame cutting machine during operation?


1. In the cutting engineering, the internal stress of the material will be released and redistributed with the removal of the material, which will lead to the displacement and deformation of the steel plate and cause the cutting size to exceed the tolerance.
2. Due to the slow flame cutting speed and long preheating time, thermal deformation will occur when the steel plate absorbs too much heat, which can be solved according to the shape and experience of the parts when compiling the CNC cutting machine program.
3. If the flatness of the plate is not good, it is easy to cause size changes after cutting.

The design and development of the frame of the fiber laser cutting machine mainly includes


1. Determine the conditions for fast, high-precision and stable operation of CNC laser cutting equipment under various working conditions and environments.
2, according to the functional requirements to determine the structure of the frame, parameters, combined with the structural characteristics of the laser cutting machine, to establish the corresponding dynamic model.
3. The influence of the structure and parameters of the frame on the static and dynamic stiffness and thermal stability of the frame is studied, and the theoretical basis is provided for the design of the frame.
4. Determine the coupling relationship between the rack and other components.
Therefore, in the design of the frame of the CNC laser cutting machine, how to arrange the metal reasonably, reduce the weight, improve the rigidity of the body, and reduce the influence of temperature change on the accuracy is the key problem to be considered in the design process.

The practical advantages of laser cutting machine in the electrical industry


Laser cutting is a high-tech developed in recent decades. Compared with the traditional shearing process, it has higher cutting accuracy, lower roughness, higher material utilization and production efficiency. Especially in the field of fine cutting, laser cutting has incomparable advantages over traditional cutting. Laser cutting is a non-contact, high-speed and high-precision cutting method that focuses energy into tiny spaces and uses high-density energy.

In the manufacturing process of electrical appliances, there are many sheet metal parts and parts, and the shape is complex, the process is difficult, and a large number of tooling and molds are required in the processing process to ensure the processing quality. The laser cutting technology in the electrical industry can not only effectively solve the above problems, to improve the processing quality of the workpiece, save processing links and processing costs, shorten the product cycle, reduce labor and processing costs, large-scale improve processing efficiency and other important role and value.

There are two basic methods for developing pattern lines cut by Hebei Chuangli intersecting line cutting machine.


1, calculation method, it through theoretical calculation, to expand the lofting. First, draw the necessary views schematically, then divide the section of the circular tube into equal parts, convert the equal points on the circumference into angles for calculation in turn, and then draw out the drawing points according to the calculation results to make the expanded pattern lines of the intersecting lines. The calculation method is fast, although it is an approximate calculation, but the more equal points, the more accurate the expansion, enough to meet the needs of the project. Because of its high degree of modularity, the complicated calculation process can be realized by program design, and the accurate drawing can also be completed by computer, which can ensure the quality of products and improve work efficiency. This paper discusses how to expand the lofting by calculation.

2, graphic method, it uses the principle of projection mapping, to expand the lofting. First, draw the relevant view of the component according to the projection principle, draw the auxiliary line, find out the real length, solid shape, etc., and then make the expansion pattern line of the intersecting line. The graphic method of drawing is cumbersome, and the error of manual drawing is large, which affects the processing quality. Although computer-aided drawing can improve the accuracy, but the degree of modularity is not high, it is not easy to program design.

Steps of Hebei Chuangli Intersecting Line Cutting Machine Cutting Auxiliary Plane to Find Intersecting Line


1. Which two revolving bodies participate in the intersection of body analysis. Shown are two cylinders whose axes intersect perpendicularly.
2. Analyze the three-sided projection of the intersecting line. As shown, the horizontal projection of the intersecting lines of the two intersecting cylinders accumulates as a small circumference, and the side projection is clamped on the large arc in the small circumference.
3. Find the special points on the intersecting line. The top view shows the first and last points 1 and 2 on the intersecting line; The leftmost and rightmost points are 3 and 4.
4. Side projection of four special points; Their front projection is shown in the figure.
5. Use the auxiliary plane method to find a series of intermediate points. The intersection point of the intersection line between the auxiliary plane and the two revolving bodies is the common point of the three surfaces of the auxiliary plane and the two revolving surfaces. The selection principle of the auxiliary plane is that the intersection line of the plane and the two rotary bodies at the same time is the simplest straight line or circle. Because straight lines or circles can be drawn directly and accurately with compasses or rulers. As shown, the positive plane can be selected as the auxiliary plane, and the intersection lines that intersect the two cylinders at the same time are all straight prime lines.
6. What is shown is to take a positive plane between the foremost and rearmost points, which is shown in the front projection of the intersection of the two cylinders. The intersection of the four intersection lines is shown as the common point of the auxiliary plane and the two cylindrical surfaces.
7. Smooth connection of each point. The projection of the steering contour line of the two rotating surfaces is not shown.
