With the development of the industrial age, intelligence has become a developed trend. More and more CNC hydraulic shearing machine has entered thousands of factories instead of mechanical shearing machine. CNC shearing machines are divided into guillotine shearing machines and swing beam shearing machines. What is the difference between them? The following is to understand the similarities and differences between them in many ways, and also help everyone is better to choose a shearing machine.

1. Maszyna do cięcia belek wahadłowych: After cutting, the shearing machine should be able to ensure the straightness and parallelism requirements of the cutting surface of the sheet. And minimize the distortion of the plate to obtain high-quality workpieces. The upper blade of the shearing machine is fixed on the knife holder, and the lower blade is fixed on the workbench. A material holding ball is installed on the workbench so that the sheet material will not be scratched when sliding on it. The back gauge is used for positioning the plate, and the position is adjusted by the motor. The pressing cylinder is used to compress the sheet to prevent the sheet from moving during cutting. The guardrail is a safety device to prevent work-related accidents. The return journey generally relies on nitrogen, which is fast and has little impact.

2. Guillotine shearing machine: The frame structure of the guillotine shearing machine adopts all-steel welding; four corners and eight sides right-angle guide rails, high precision, good rigidity, and hydraulic preloading. The hydraulic system adopts a two-way cartridge integrated valve; the whole system adopts and can be equipped with a stroke digital display, photoelectric protection device, and mobile workbench (for easy replacement of molds), guillotine shearing machine has double action of the upper slide and lower hydraulic cushion function. The working pressure stroke can be adjusted within the specified range according to the process requirements. And the operation is simple and convenient, and the button is used for centralized control.

1. The clearance of the bearing connection between the swingarm and the swing frame body of the swing beam shearing machine cannot be eliminated, and the accumulated cutting accuracy error of the clearance and blade clearance is generally above 0.1mm. Both sides of the guide rail of the guillotine shearing machine are supported by two needle roller bearings, and each of the front rails has a bearing with a compact disc spring on the back to form three-point support. So that the added accuracy error between the front and rear rails and the blade gap is less than 0.04mm, so the cut material is smoother and has no burrs.

2. The knife holder body of the swing beam shearing machine is arc-shaped. It uses arc point contact to ensure the straightness of the cut material. The guillotine shearing knife holder moves vertically and linearly relative to the lower blade to ensure the distortion of cutting sheet material is small, and the straightness is more accurate.

3. Because the force point of the knife holder and the blade of the swing beam shearing machine are not in the same straight line and the distance is relatively long, the knife holder is prone to fatigue and deformation after long-term work, which makes the phenomenon of the knife more serious, causing the cut material to be cut with burrs. The guillotine shearing machine is not prone to deformation because the cylinder, the knife rest, and the knife-edge are in the same straight line and move perpendicular to the lower knife edge.

Zasada działania

1. Swing beam shearing machine: The upper blade is fixed on the knife holder, and the lower blade is fixed on the workbench. The tool post moves back and forth in an arc around the fixed axis to realize multiple linear cutting of the plate.

2. Guillotine shearing machine: The oil cylinder is installed vertically on both sides of the machine, and the vertical movement of the oil cylinder drives the knife holder to move back and forth in the vertical direction, so as to realize the linear cutting of the metal sheet.

Blade Life

1. The swing beam shearing machine adopts oblique blade cutting. The upper blade has 2 blades and the lower blade has 4 blades. Due to its simple structure, low failure rate, high shearing efficiency, and material without bowing, warping, twisting, and deformation, it is used widely. Because the blade point of the swing beam shearing machine knife holder moves in an arc shape when working, only the diamond blade with double-sided blades can be used.

2. The guillotine shearing machine has 4 cutting edges on the upper blade and 4 cutting edges on the lower blade. During use, the blade surface can be changed. The guillotine shears have more blade edges and longer service life. The vertical cutting of the blade makes the cutting process more powerful and efficient and improves the cutting quality.

Knife Gap

1. The swing beam shearing machine is equipped with a fast knife gap adjustment mechanism, which can adjust the knife gap that is conducive to cutting according to different plate thicknesses and materials. And is equipped with an accurate parameter table for reference selection, and obtains satisfactory cutting through a reasonable knife gap quality. As the tool post rotates, the cutting angle and cutting gap of the shearing machine will change. The shearing machine has the function of manually adjusting the knife gap, just turn the handle.

2. The guillotine shearing machine adopts a three-point roller guide rail structure, and the front pre-compressed guide rail makes the tool holder always stick to the upper and lower guide rails for repeated movement without gaps. The guillotine shearing machine has the function of electrically adjusting the knife gap, which can be adjusted more conveniently and accurately through the system, which is conducive to obtaining better cutting quality.

Angle Adjustment

1. Swing beam shearing machine: The cutting angle is not adjustable, which makes the shearing machine more limited in use. It is more single in terms of plate and function, and it is not suitable for the shearing of thick plates. The cutting angle is a fixed angle, and the cutting speed cannot be adjusted.

2. Guillotine shearing machine: The cutting angle can be adjusted, and it can be adjusted for different plates. It is more widely and convenient to use, and there are more degrees of freedom when cutting thick plates. It realizes angle adjustment by adjusting the oil volume of two engineering oil cylinders connected in series up and down quickly. The cutting angle is enlarged, the cutting capacity is increased, the cutting angle is reduced, the cutting speed is increased, and the electric energy and working time are saved. The curvature of the sheet is effectively reduced.

Processing And Using

1. Swing beam shearing machine: The knife gap needs to be adjusted manually; the cutting angle cannot be adjusted; the effect is poor when cutting thick plates. But the price is relatively low. From the perspective of cost-saving, if the precision of the cutting plate is not high, and the thickness of the cutting plate is relatively thin, you can buy a swing beam shearing machine.

2. Guillotine shearing machine: The knife gap can be adjusted electrically, and the accuracy can be higher at the same time, reaching 2 times that of the swing beam shearing machine. The cutting angle can also be adjusted according to different plates. If processing thick plates exceeding 8mm, it is recommended to use a guillotine shearing machine, because the principle of the swing beam shearing machine limits its precision in cutting thick plates. The appearance is an integrally welded frame structure, and after vibration aging treatment, the machine tool has good rigidity, high precision, and good accuracy retention. However, the production cost of the guillotine shearing machine is relatively high, so the selling price is also relatively high.

Corresponding Configuration

1. Swing beam shearing machine: It is usually equipped with an E21S system, used to control the back gauge stroke and cutting edge stroke, and can store up to 40 groups of programs. The structure can be equipped with the front feeding that can automatically feed and the pneumatic back feeding that can improve the overall cutting accuracy and performance of cutting thin and long plates. The control of the front feeding can be equipped with another system.

2. Guillotine shearing machine: In addition to the E21S system, systems such as P40 and DAC360S are often selected. In addition to the front feeding and pneumatic rear support, servo motors are often configured in structure. When using a system such as P40, there is no need for a separate system for front feeding, and the P40 system can be used directly.

Nożyce hydrauliczne CNC Recommendation

If it is only used for regular use, cutting thinner plates, the precision is not high, and even the frequency of use is not high. In combination with economic aspects, it is recommended to choose a swing beam shearing machine. However, if a large number of plates need to be cut, and the plates are thicker and require high precision, guillotine shearing machines are more recommended from the perspective of cost performance.
