A plate shearing machine is a machine that cuts metal sheets by reciprocating linear motion of one blade relative to another blade. It applies shearing force to metal sheets of various thicknesses by means of the moving upper blade and fixed lower blade, with a reasonable blade clearance, causing the sheets to fracture and separate into the required sizes. Shearing machines belong to a type of forging machinery with the main purpose of metal processing industry. The products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automotive, power, electrical, decoration and other industries to provide required specialized machinery and equipment.
Hydraulic shearing machines have a small torque and a shaft system mainly for transmitting motion. They require a coupler with high transmission accuracy, and a flexible coupler with metal elastic elements is preferred.
The mechanical synchronization device has a simple structure and low cost, and can obtain a certain synchronization accuracy, but its ability to withstand off-center loads is poor, so it is only suitable for medium-sized hydraulic sheet metal bending machines. Due to various factors such as manufacturing errors, assembly errors, installation errors, shaft loads, relative displacement between components, and temperature changes (thermal expansion, cold shrinkage), the two shafts connected by the hydraulic shear machine coupler produce deformation, base deformation, bearing damage, and relative displacement between parts.
CNC hydraulic shearing machines, a kind of automatic shearing machine, are operated by various parts coordinated with each other. Specific accessories can be divided into the following categories: first, some accessories related to circuits, generally including various buttons, indicator lights, control contacts, transformers, switches, motors, etc. There are also accessories related to the hydraulic system, including oil pumps, various specifications of valves, pressure gauges and switches, level gauges, oil pipeline fittings, sealing rings, etc. Finally, there are other mechanical accessories of CNC hydraulic plate shearing machines, including blades, bearings, knife racks, various models and specifications of bolts, gears, optical rods, etc.
The basic components of CNC hydraulic shear cutting machine includes processing programs, input devices, numerical control systems, servo systems, auxiliary control devices, feedback systems, and machine tools. Processing programs can be manually compiled, and complex processing requirements can be drawn on computers, and then generate processing programs. The program can be manually input on the numerical control system panel, or transmitted through cables via the computer communication port. Alternatively, it can also be transmitted via a computer USB interface.
