Structural mechanics: "box-type" hollow torsion design of tool holder
The core stress part of the gantry shear is the lower slider carrying the blade. When cutting solid steel with a thickness of more than 50 mm, the tool holder will bear a huge eccentric reaction force.
-Box-type rigid structure: The interior of the tool rest is not solid, but a box-type structure welded by complex internal ribs.
-Technical depth: According to the mechanics of materials, the box structure has the highest torsional modulus for the same weight. This design can effectively absorb the radial component force generated by instantaneous shearing, prevent the tool rest from "wedging" in the guide rail, and ensure that the blade clearance remains constant under thousands of tons of pressure.
-"Self-locking" mounting position of the blade seat: The slot of the blade seat is designed with a slight inclination angle to match the high-strength pressure plate.
-Physical logic: The upward component force of the shearing force itself is used to squeeze the blade more tightly on the base during operation, thus realizing the physical self-locking of "more shearing, more tightening" and completely solving the industry problem of easy fatigue fracture of blade bolts in heavy shearing.
Hydraulic logic: "Zero impact" instantaneous pressure relief control of master cylinder
At the moment when the heavy gantry shear cuts the metal, the system pressure will drop instantaneously from the peak value, which will produce severe mechanical vibration.
-Logic relief circuit: the system is equipped with a special logic relief valve group. Within the millisecond time after the shearing action is completed, the residual pressure of the high-pressure chamber is smoothly introduced into the oil return circuit through the multi-stage damping orifice.
-Operation value: This "subtraction logic" eliminates the sharp rebound when energy is released, reduces the structural vibration of the whole machine by more than 60%, not only protects the hydraulic pump, but also greatly prolongs the service life of the plant foundation.
-Hydraulic cushion at the end of the stroke: before the shear cylinder reaches the bottom dead center, the flow rate is reduced by the built-in cushion sleeve.
Effect: The rigid collision between the tool table and the bottom of the frame is prevented, and the "flexible landing" is realized.
Feeding process: three-dimensional space pre-compression of side pressure mechanism
