300t Four Column Brake Pad Making Machine Metal Deep Drawing Hydraulic Press Machine

Product Description

Product Feature
Four-column hydraulic press machine adopts three beams and four column structure, the hydraulic system adopts a cartridge valve oil circuit, and the electrical system adopts a relay or PLC control circuit, with adjustment and semi-automatic operation mode, the whole machine structure is a simple, compact, economic and reasonable, reliable action, long service life, small hydraulic impact, reduce the connection pipeline and leakage.
·We have designed the Single-Column Hydraulic Press with different power ranges, from 25 to 400 tonnes.
·Specifically designed to perform work involving deep drawing, stamping,die-cutting, forming, etc.
·The latest generation series hydraulic presses now feature a wide range of uses including the possibility of incorporating these machines in automatic production lines.
Details Images
Four-column single-movement hydraulic press machine for sheet metal deepdrawing adopts a counter-stretching process and the hydraulic pad can be installed in or outside the table. The hydraulic system uses cartridge valves and the electrical system is automatically controlled by PLC.lt is equipped with point-action and semi-automatic operation functions, and the stroke, pressure, and speed of each moving part are independently adjustable within a certain range to meet the needs of metal products forming parts. It can also be equipped with a beating device, moving table, punching and cutting buffer device, grating safety protection device, and man-machine interface according to the user's needs.
Applications
·Auto parts: automobile body covering parts, braking, fuel tanks, chassis, axle case, bumper
·Household appliances: washing machine, TV, refrigerator, air conditioning, rice cooker, and other parts
·Kitchenware: sink, tea set, and Other kinds of containers.
Stress Analysis & Finite Element Analysis
The CAE software SOLIDWORKS is used as the method to analyze the linear static construction, stress, and deformation for press break and laser cutting machine frames. So for complicated structures, highly complex loadings, transient modeling, and a combination of the above, FEA makes sense.
Features
·Steel welded body, tempering treatment or VSR(Vibratory Stress Relief), high rigidity, accuracy and stability.
·Pneumatic dual balance cylinders, which balance the slide and punch weight to reduce noise and impact.
·The crankshaft undergoes grinding treatment after high-frequency quenching.
·Lengthened six-face rectangle guide with a surface of bronze plate.
·Vertical located crankshaft, compact structure.
·PLC control and imported safety duplex valve.
·Wet type combined multi discs friction clutch and brake.
·Hydraulic overload protected.
Electric Installation And Safety
The control panel features a switch enabling the user to select the desired type of work in a manual, semi-automatic, or automatic position and a switch to select either the fast speed or slow speed.
Electrical and hydraulic maneuvers are redundant and self-controlled.
They incorporate an additional safety block and self-control devices for maneuver and safety.
It includes the verification and certification of the correct operation and the safety distance for the photocells.
