Operating Procedure for a Combination Punching and Shearing Machine
A combination punching and shearing machine is a machine tool used to create a clean and precise hole or sheared edge in a variety of materials. The outcome is dependent upon a well-trained and knowledgeable operator as much as the machines mechanical ability. The fabrication process for both punching and shearing require following certain procedures and standards related to workpiece material, tooling, cutting parameters and safety precautions.
Safety
Observe all safety precautions and guidelines before, during and after the operation of a combination punching and shearing machine. Make sure that the guards and safety covers are installed, and the operator has all the necessary safety equipment, including safety goggles and gloves. Inspect the machine and tools to ensure that they are in safe working order before each use.
Workpiece Preparation
Review the material type and thickness of the workpiece to be machined and make sure to select the appropriate tooling and cutting parameters. It is important to note that a standard setup procedure should be used regardless of the type of material. Clamp the workpiece securely in the appropriate fixture to allow for smooth slicing and punching, while eliminating unnecessary loading and vibrations.
Tooling Selection
Select the appropriate tooling for the type of material that needs to be worked. Be sure to choose tooling that has been designed for the specific purpose of cutting, punching, or shearing. Ensure that the tooling is sharp and of the desired dimensions, as it affects the quality of the finished product.
Operation
Before each cycle, ensure that the workpiece is set up correctly and that the tooling is ready for use. Turn the power switch on, and move the switchover from testing mode to production mode. Activate the combination punching and shearing machine, observing the movements of the shearing blade and punching bit carefully.
Adjust the cutting depth and speed, as required. Make sure that the shearing blade and punching bit are able to complete the desired holes and cuts without any hindrances such as material build up or obstruction.
Finished Product
Once the punching and shearing process is complete, check the workpiece to ensure that the desired outcome has been achieved. Inspect the quality of the cutting and punching performed by the combination punching and shearing machine in all three dimensions. Make sure that any burrs or sharp edges are removed and that the sheared edges are of the desired length, width and shape.
Maintenance
Regular maintenance of the combination punching and shearing machine is essential in ensuring its proper functioning and producing quality products. Check for any misalignment of parts, and make adjustments and replacements as needed. Clean the workpiece and machine parts after each use, and check for any abnormal wear or damage.
Conclusion
Following the procedures and safety precautions outlined above will help ensure the successful operation of a combination punching and shearing machine. Proper tool selection, workpiece preparation, machine operation, quality finished product, and regular maintenance will greatly increase the productivity and life of the machine.
