Press brakes are used to bend and fold metal by pressing it into a die. There are several types of press brakes. Examples include a hydraulic press brake, folding equipment, bending machine, press brake tooling, CNC brake press, and a sheet metal press brake. A hydraulic press brake is designed for both specialized sheet metal work and continuous production applications. A hydraulic press brake is designed to handle tough industrial production jobs from single-cycle operations to automated cell components. Folding equipment can be used to stiffen new metal panels that would otherwise flap around, and to put lips on pieces of sheet that would normally need screws passed through the front face. A bending machine forms angles in sheet metal. Press brake tooling is used in cold-forming metal sheets or strips into desired sections. A CNC brake press is a computer numerically controlled, fully automated brake press with extensive bending capacity and networking function. A sheet metal press brake is used to bend and form sheet metal. Other press brakes are commonly available.
Functions and Specifications
Press brakes have a variety of functions and specifications. A hydraulic press brake utilizes electrohydraulic control that is based on linear measurement and a control system, which provides reliable, accurate operation in sheet metal work. A press brake manufacturer offers options on a hydraulic press brake including hydraulic clamping, CNC crowning, adapters for European or other style tooling, robot interface, work area illumination, cooler for hydraulics and electrical cabinet over +30 °C, +85 °F, light curtains, and a special voltage transformer. Folding equipment is available with a variety of specifications including a 2160 x 1500 x 2mm capacity. Folding equipment is also available with other features such as backlash free servo gear motors that provide better accuracy and 30% higher speeds, dual drive tool changer, automatic clamp folding tools with integrated tab, offline tools, and fast infeed and outfeed systems. A bending machine can bend sheet metal to almost any angle. A bending machine integrates cells of right angle shears, laser cutters, turret punch/presses and bending units to form a seamless system. The bending machine cells can load, scrap, remove, sort and stack. The overall bending machine system can load and stack sheets, look after component stack buffering, provide cell to cell transfer, and remove bent components. Press brake tooling is utilized to eliminate marking aluminum, stainless steel, and precoated steels during bending, Press brake tooling includes markless tooling film, markless bottom tools and adiprene blocks used as universal bottom tools. A CNC brake press controller is an input/output device into which an operator keys in machine coordinates (ram and back gage locations) and the controller will then position the axes according to those coordinates. Press brakes are designed and manufactured to meet most industry specifications.
Press brakes are used in many industries. Examples include the automotive and aircraft industries, where metal panels are a constant need. Housing and cabinets are also manufactured with the use of a sheet metal press brake. Press brakes should be operated in accordance with Occupational Safety and Health Administration (OSHA) guidelines.
