Parts of the Transfer Press

Main Cylinder: The main cylinder is the most important part of a hydraulic press. A cylinder develops the pushing or pulling force required to carry out the desired operation, using pressurized hydraulic fluid.

Blank Holding Cylinder: Blank holding cylinders are used in those hydraulic presses in which raw material which is to be pressed must be held firmly in position, at the time of pressing operation by the main cylinder. For example, in the deep drawing press, the blank is held by a block-holding cylinder at the time of deep Drawing operation.

Ejector Cylinder: These hydraulic cylinders are usually mounted below the bottom plate, and used to eject component which is already pressed by the main cylinder, and requires some force to get removed from the die in which they get pressed. For example, pressed components stuck in the die after cold forming ejected by the ejector cylinder.

Top Platen: Top platen is a steel fabricated or steel cast structure located upper side of a vertical press, and withstands compressive and bending loads developed by hydraulic cylinders.

Bottom Platen: The bottom platen is a steel fabricated or steel cast structure located lower side of a vertical hydraulic press, and withstands compressive and bending load developed by a hydraulic cylinder. It is also used as a press table in down-stroke presses.

Moving Platen: Moving platen is also a steel fabricated or cast structure, Located between the main hydraulic cylinder and the pressing table. It is attached to the Ram of the cylinder and guided by the side columns of the press. Moving the platen exerts a force on the job placed on the press–table.

Column, Nut & Chuck-nut: Columns are round bars or fabricated structures. It binds the top and bottom platen together firmly. Round bars are threaded at ends and nuts are provided to hold the platen in position,
check- nuts are provided to avoid loosening of main nuts.

Guides: Guides are provided to ensure perfect parallel and vibration-free movement of the moving platen. Guides may be Round, V-Type, or flat, depending upon the use and type of columns.

Press-Table: Press-Table is a thick steel plate either an integral part of the bottom plate or separately bolted to it. It is perfectly machined and provided with T-slots or tapped holes for mounting dies and fixtures. The moving platen attached to the ram travels forward and exerts a force on jobs placed on this pressing table to carry out the pressing operation.

Power Pack Units: This is the most important part of the machine. It pumps oil under controlled pressure and flows into the cylinder to impart its desired speed and to develop desired force. The power pack consists of hydraulic valves, a pump, an oil tank, a cooler, hydraulic accessories, a manifold block, and piping, etc. The hydraulic pump may be driven by an electric motor or I.C. engine.

Control Panel: It controls the overall operation and performance of the hydraulic press, by controlling the power pack unit. It consists of a motor starter, push-button, indicator lamp, current and voltage indicator, contactor, timer, etc. The control panel gets it feedback from the hydraulic press by means of a limit switch, pressure switch, proximity switch, thermocouple, etc.

Manifold Block and Hydraulic Piping: Every hydraulic valve and pump has a number of oil port [holes] such as a suction port, delivery port, tank line [return line] port, drain line port, pilot line port, oil port for forward motion of the cylinder, oil port [B] for the return motion of the cylinder, etc.

All these ports [oil holes] should be interconnected with each other, as well as with the oil tank and hydraulic cylinder in the correct manner and sequence for the correct operation and motion of the press. This interconnection of various hydraulic component by means of special seamless steel pipe and special end-connection fittings are called hydraulic piping.

To reduce extensive piping, leakage, and maintenance, hydraulic valves are mounted on a solid metal block, and their oil ports are interconnected by drilling holes in the metal block. This solid drilled metal block is called a manifold block.

Ram, Piston-rod: Piston-rod is a round bar, which is attached to the piston, and moves in and out from the cylinder for pushing and pulling operation. For small diameters, it is called, a piston – rod. When the diameter of the piston rod is the same as the cylinder inside diameter, the piston rod is called a Ram. But in general, all the piston-rod of higher diameter is called ram.

How do Transfer Presses function?

How do Transfer Presses function?

Hydraulic transfer presses use hydraulic pressure to transfer a part from one station to the next during the manufacturing process. The machine consists of multiple workstations, with each station dedicated to a specific operation such as stamping, forming, or trimming. The part is moved from one station to the next using a transfer mechanism, typically a hydraulic cylinder or servo motor.

The press has a hydraulic power unit (HPU), which is responsible for generating the necessary hydraulic pressure to operate the machine. The HPU consists of a pump, motor, accumulator, and control valves. The pump draws fluid from a reservoir and delivers it to the hydraulic cylinders or motors that power the machine. The accumulator stores hydraulic fluid under pressure, which helps to maintain consistent pressure during the operation of the press.

The press also has a control system, which is responsible for managing the movement of the part between workstations. The control system uses sensors to monitor the position of the part and the press, and adjusts the movement of the transfer mechanism accordingly. The control system can also be programmed to adjust the speed and force of the press based on the requirements of the specific operation.

The transfer mechanism is typically a hydraulic cylinder or servo motor that moves the part between workstations. The cylinder or motor is controlled by the press’s control system and can be programmed to move the part in any direction or orientation required for the specific operation.
