Hydraulic press

The basic principle of the hydraulic press is that the oil pump delivers the hydraulic oil to the integrated cartridge valve block, and the hydraulic oil is distributed to the upper or lower chamber of the cylinder through the check valve and the relief valve. Under the action of high pressure oil, the cylinder moves.A hydraulic press is a device that uses liquid to transfer pressure.A liquid obeys Pascal's law when it transmits pressure in a closed container.The hydraulic transmission system of the four-column hydraulic press is composed of power mechanism, control mechanism, executive mechanism, auxiliary mechanism and working medium.The power mechanism usually uses the oil pump as the power mechanism, which is generally the product oil pump.In order to meet the movement speed of the actuator, choose one oil pump or more oil pumps.Low pressure (oil pressure less than 2.5MP) gear pump;Vane pump for medium pressure (oil pressure less than 6.3MP);High pressure (oil pressure less than 32.0MP) for the plunger pump.

Application: pressure processing and forming of various plasticity materials, such as extrusion, bending, deep drawing of stainless steel plate and cold pressing of metal parts, and can also be used for powder products, grinding wheel, bakewood, resin thermosetting products.

Elbow In a piping system, an elbow is a pipe fitting that changes the direction of the piping.According to the Angle, there are 45° and 90°180° three most commonly used, and according to the engineering needs, there are also 60° and other abnormal Angle elbows.Elbow materials include cast iron, stainless steel, alloy steel, malleable iron, carbon steel, nonferrous metal and plastic, etc.Pipe connection methods are: direct welding (the most common way) flange connection, hot melt connection, electric fusion connection, threaded connection and socket connection.

According to the production process, it can be divided into: welding elbow, stamping elbow, push elbow, casting elbow, butt welding elbow, etc.Other names: 90 degree bend, right Angle bend, love and love bend, etc.

The intermediate frequency elbow machine equipment mainly includes: frame, main cylinder support plate (including the main cylinder), movable push plate, front support plate, semi-automatic feeding mechanism, intermediate frequency coil adjustment frame (including intermediate frequency heating coil), intermediate frequency power supply, electrical control system and so on.Our company approximates the production of elbow machine, tee machine, pipe bending machine, medium frequency pipe expanding machine and other pipe fittings equipment
