Straight Side Press: Guide to High-Precision Metal Forming

What is a Straight Side Press?

A straight side press is a highly precise equipment used in the manufacturing of metals. The design of this machine is specialized to shape the metal parts and make them ideal for industries. This type of structural configuration resists deflection under heavy load. It is mostly used in the manufacture of automobiles, aircraft and appliance manufacturing.

Key Components of Straight Side Press

Straight side presses are constructed with the following parts which serve primary functions within the entire processes of metal formations.

• Frame

The frame is the part which imparts strength on the press and minimizes the deflections caused by high loads. The straight sides provide support and rigidity.

• Crown

The crown is the top part of the press machine that contains the critical units for the main drive. It serves to conceal all units that serve the power actuators of the press including the driving unit and the operational controls that carry out the functions of the press.

• Slide (Ram)

The ram is the moving part hence it is used in the slide to convey action through impressing force to the work piece. Slides are designed to be vertically oriented and are intended to thrust mass’s rage against a die or bolster plate, thus creating area deformation of the mass.

• Bolster Plate

Bolster plate is a detachable plate which is subjected in the press bed area. It assists the die by providing a flat area, thus withstanding the force acted during each cycle. It ensures perfect stamping operations.

• Bed

The bed is considered to be the primary component of the straight side press. The bed bears the work-piece and the bolster plate. It has to be strong and does not displace under high operational pressures.

• Drive Mechanism

The component responsible for moving the slide is the drive mechanism as it forms the metal forming force. It consists of mechanical type, hydraulic type and servo driven types of drive mechanisms. Mainly, straight side presses use a crankshaft or toggle mechanism to change rotational motion into linear force.

• Guides

Guides guarantee that the slide does not move in more than a definite direction in vertical motion. They assist to reduce lateral movement and hence increase precision in metal forming applications.

• Clutch and Brake System

The clutch engages the drive thus causing the slide to start moving while the brake system will bring it to stop. This repetitive process makes for safe and controlled operations.

• Safety Devices

Safety devices are placed in order to protect the operators from outside contact and cut off other activities if an emergency situation takes place. Typical ones are light curtains, emergency buttons, and sensors.

All these elements are integrated in such a way as to make it possible for the straight side press to work with metals with great consistency and precision and in a safe manner.
