The oil cylinders of the guillotine shearing are 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, thereby realizing linear cutting of the metal sheet.
The swing beam shearing machine upper blade is fixed on the knife holder, and the lower blade is fixed on the workbench. The tool holder moves back and forth in an arc around the fixed axis to realize multiple linear shearing of the plate.
Compared with ordinary shears, the swing beam shearing machine adopts oblique blade shearing. 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 poor sheet metal after shearing It is widely used due to bowing, warping, and distortion.
The guillotine shearing machine has 4 blades on the upper blade and 4 blades on the lower blade. In the process of use, the blade surface can be changed. The guillotine shears have more blade surfaces and longer service life. The vertical cutting of the blade makes the cutting process more powerful and efficient and improves the cutting quality.
The swing beam shearing machine is equipped with a fast blade gap adjustment mechanism, which can adjust the blade gap that is conducive to shearing according to different plate thickness and materials, and is equipped with an accurate parameter table for reference selection, and obtains satisfactory cutting quality through reasonable blade gap. As the tool post rotates, the shearing angle and shearing gap of the swing beam shearing machine will change.
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. When cutting, the system will electrically adjust the knife-edge gap according to the needs of different sheets to obtain better cutting quality.
The shearing angle of the swing beam shearing machine cannot be adjusted, which makes the swing beam shearing machine more limited in its use, and it is more single in terms of plate and function, and it is not suitable for the shearing of thick plates.
NS shear angle of the guillotine shearing machine can be adjusted, and it can be adjusted for different plates. It is more widely and convenient to use and has more freedom when cutting thick plates.
Processing and use
The blade gap of the swing beam shearing machine 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 shearing plate is not high, and the thickness of the shearing plate is relatively thin, you can buy a swing beam shearing machine.
The blade gap of the guillotine shearing can be adjusted electrically, and the accuracy can be higher, reaching twice that of the pendulum shears. 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 pendulum 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 shears is higher, so the selling price is also higher.
