The hydraulic shearing machines (guillotine shear) is a machine that uses one blade relative to another as a reciprocating linear motion of shear plates. By means of a moving upper blade and a fixed lower blade, a reasonable blade clearance is used to apply a shear force to the metal plates of various thicknesses so that the plates can be broken and separated according to the required size. The hydraulic shear for sale belongs to a kind of forging and pressing machine, the main function is the metal processing industry. Products are widely used in aviation, light industry, metallurgy, chemical industry, construction, ships, automobiles, electric power, electrical appliances, decoration, and other industries to provide the need for special machinery and complete sets of equipment.
The sheet metal shearing machine shall be able to ensure the straightness and parallelism of the shear plane of the sheared sheet material after shearing, and minimize the distortion of the sheet material so as to obtain a high-quality workpiece. The upper blade of the hydraulic sheet metal shears is fixed on the tool rest and the lower blade is fixed on the work table. The work table is equipped with a supporting ball so that the sheet material will not be scratched when sliding on it. The rear stop is used for the positioning of the sheet metal, and the position is adjusted by the motor. The pressure cylinder is used to compress the sheet metal to prevent it from moving during shearing. The guardrail is a safety device to prevent accidents at work. The return journey usually depends on nitrogen, the speed is fast, the impact is small.
The hydraulic shearing machine can be divided into hydraulic swing beam shears and hydraulic guillotine shearing machine.
hydraulic swing beam shears
hydraulic guillotine shearing machine
Simple structure, easy to install and repair
The structure is relatively complex, a little hard to install and repair
The cutting frame arc movement
The cutting frame linear movement
The cutting frame mechanical synchronization
The cutting frame hydraulic synchronization
The cutting angle is fixed
The cutting angle can be adjusted
Upper blades – two-sided
Upper blades – four-sided
The cutting precision of the guillotine shearing machine is higher than the normal shearing machine, and cutting the speed of the guillotine shearing machine is more quickly than the normal shearing machine. Since there are four sides of the blade of guillotine shear can be used for cutting, so the blades of guillotine can be used longer than the shearing machine. If you don't have a high demand for precision, you can choose the shearing machine, because it’s cheaper than the guillotine metal shear.
ZYMT hydraulic sheet metal shear using UG (finite element) analysis method and computer-aided optimization design. The fuselage adopts the whole steel plate welding structure, which has good strength, stiffness, and vibration resistance. Internal stress is eliminated by tempering. The overall frame shall be sand cleaned and sprayed with anti-rust paint.
The working table is provided with an auxiliary knife seat for micro-adjustment of the blade, equipped with a feeding ball, which is easy to operate. The blade gap adjustment adopts a step-less adjustment mechanism to meet the shearing needs of different plate thickness and material. Under the rectangular blade, four cutting edges can be used to cut, extending the service life of the blade. Automatic counting of shear times reduces the checking work.
An advanced integrated hydraulic system reduces pipeline installation and ensures high reliability and safety in machine operation. After the oil is fed by several pressing oil cylinders mounted on the supporting plate in front of the frame, the pressing head presses down to tighten the plate after overcoming the tension of the pulling spring. When the shearing is complete, it is reset by the pull of the pulling spring. The size of the pressing force increases with the increase of the thickness of the sheared plate. Electrical components and materials in line with international standards, safe and reliable, long life.
The front block material is placed on the workbench surface, and the value is indicated by the ruler to adjust the active block to reach the desired block material value. It is convenient to use the front stop material when shearing the thin steel plate.
The adjustment of the rear stopper is driven by the motor to decelerate the direct lead screw. The back gauge adopts a precision ball screw to position and is supported by a high precision smooth rod. H type synchronous belt synchronous wheel drive, high transmission accuracy, low noise.
