Press Briking Machine Operating Procedures
1. Introduction
Press braking machines have been widely used in metal working, in order to bend or shape metal parts with bending tools. They can be used to create complex objects such as car parts, furniture and electronics components. Press Braking machines generally consists of a clamping device, a control system, and a bending tool. The bending tools are usually called dies because they transfer the force from the press brake to the workpiece. This procedure outlines the steps involved in operating a press brake.
2. Preparation
Before beginning, operators must be sure that the press brake, the dies and the workpiece are in good condition. Check the machine for any signs of loose parts, damaged motors and any other abnormalities. Ensure that the adjustable die back-gauges are adjusted correctly; the depth of the bend should be adjusted according to the thickness and the type of metal. Check that the dies are the correct size and shape for the particular job and secured firmly in place. Additionally, verify the material that will be completed to ensure that it has no sharp edges or other damage.
3. Operation
Turn on the press brake and set the desired pressure and stroke parameters. Make sure that the work-piece is properly aligned in the press brake and that the two dies are meshed correctly. When the dies are properly connected, press the start button to begin the bending operation. Keep pressure on the dies to ensure that the part is bent correctly. The force of the press brake will determines the amount of pressure needed.
Once the desired depth of bend is achieved, press the stop button to stop the machine mid-cut. Ease the pressure off the dies, adjust the back gauge, and remove the workpiece. Inspect the workpiece for accuracy. If defects are present, readjust the parameters and run the bend again.
4. Maintenance
After each job, inspect the press brake for any signs of wear and tear. Adjust the adjustable die back-gauges as needed to ensure that they are adjusted correctly for the next job. Clean and lubricate all the moving parts such as the slides and the linkages before re-installing the press brake. Secure all bolts and tighten any of the nuts or bolts that have come loose.
5. Summary
Press Brakes are a staple of metalworking and can be used to bend and shape almost any type of metal. They are powerful machines, so proper precautions should be taken when operating. Be sure to clean and lubricate the press brake regularly, and adjust the adjustable die back-gauges as needed. Understand the steps needed to properly operate a press brake and you’ll be able to quickly and safely produce accurate parts.
