Adjusting the parallelism of the pressing plate in a servo hydraulic press machine is a crucial task that directly impacts the quality and precision of the pressing operations. As a supplier of Servo Hydraulic Press Machine, I understand the significance of this process and the challenges that operators may face. In this blog post, I will share some practical tips and techniques on how to effectively adjust the parallelism of the pressing plate in a servo hydraulic press machine.
Understanding the Importance of Parallelism
Parallelism refers to the condition where two or more surfaces are equidistant from each other at all points. In a servo hydraulic press machine, the parallelism of the pressing plate is essential for ensuring uniform pressure distribution across the workpiece. If the pressing plate is not parallel, it can lead to uneven deformation, inconsistent product quality, and even damage to the tooling and the machine itself.
For example, in a stamping operation, if the pressing plate is not parallel, one side of the workpiece may be subjected to more pressure than the other, resulting in uneven thickness and dimensional variations. This can affect the functionality and performance of the final product. Therefore, maintaining proper parallelism is crucial for achieving high-quality results in servo hydraulic press operations.
Tools and Equipment Required
Before starting the parallelism adjustment process, it is important to gather the necessary tools and equipment. Here are some of the commonly used tools:
- Dial Indicators: These are used to measure the deviation in parallelism between the pressing plate and the worktable or other reference surfaces. Dial indicators provide accurate readings and are essential for precise adjustments.
- Feeler Gauges: Feeler gauges are used to measure the clearance between two surfaces. They are useful for checking the parallelism of the pressing plate by measuring the gap at different points.
- Wrenches and Screwdrivers: These are used to loosen and tighten the bolts and screws that hold the pressing plate in place. Make sure to use the appropriate size and type of wrenches and screwdrivers to avoid damaging the machine.
- Level: A level is used to ensure that the machine is properly aligned and leveled. This is important for accurate parallelism adjustment.
Step-by-Step Guide to Adjusting Parallelism
The following is a step-by-step guide on how to adjust the parallelism of the pressing plate in a servo hydraulic press machine:
Step 1: Prepare the Machine
- Clean the Machine: Before starting the adjustment process, clean the pressing plate, worktable, and other relevant surfaces to remove any dirt, debris, or lubricants. This will ensure accurate measurements and prevent interference during the adjustment.
- Check the Machine Alignment: Use a level to check the alignment of the machine. Make sure that the machine is level and stable. If the machine is not level, adjust the leveling feet until the machine is properly aligned.
- Inspect the Tooling: Check the tooling for any signs of wear, damage, or misalignment. Replace any worn or damaged tooling components to ensure proper operation.
Step 2: Mount the Dial Indicators
- Position the Dial Indicators: Mount the dial indicators on the worktable or other reference surfaces in a way that they can measure the deviation in parallelism between the pressing plate and the reference surface. Make sure that the dial indicators are securely mounted and that the probes are in contact with the pressing plate.
- Zero the Dial Indicators: Set the dial indicators to zero at the starting point. This will provide a reference for measuring the deviation in parallelism.
Step 3: Measure the Parallelism
- Lower the Pressing Plate: Slowly lower the pressing plate until it makes contact with the worktable or other reference surface. Make sure that the pressing plate is evenly distributed across the surface.
- Take Readings: Use the dial indicators to measure the deviation in parallelism at different points on the pressing plate. Take readings at multiple locations, such as the corners and the center of the pressing plate, to get a comprehensive understanding of the parallelism.
- Record the Readings: Record the readings obtained from the dial indicators. This will help you track the progress of the adjustment and determine the necessary corrections.
Step 4: Identify the Deviation
- Analyze the Readings: Compare the readings obtained from the dial indicators to determine the deviation in parallelism. Look for any patterns or trends in the readings to identify the areas that need adjustment.
- Determine the Direction of Adjustment: Based on the readings, determine the direction in which the pressing plate needs to be adjusted. If the deviation is positive, it means that the pressing plate is higher on one side and needs to be lowered. If the deviation is negative, it means that the pressing plate is lower on one side and needs to be raised.
Step 5: Make the Adjustments
- Loosen the Bolts and Screws: Use the appropriate wrenches and screwdrivers to loosen the bolts and screws that hold the pressing plate in place. Make sure to loosen them gradually and evenly to avoid causing any damage to the machine.
- Adjust the Pressing Plate: Depending on the direction of adjustment, use shims or other adjustment methods to raise or lower the pressing plate. Start by making small adjustments and recheck the parallelism after each adjustment.
- Tighten the Bolts and Screws: Once the desired parallelism is achieved, tighten the bolts and screws that hold the pressing plate in place. Make sure to tighten them evenly to ensure that the pressing plate is securely held in position.
Step 6: Recheck the Parallelism
- Lower the Pressing Plate Again: After making the adjustments, lower the pressing plate again and recheck the parallelism using the dial indicators. Take new readings at the same points as before to verify the accuracy of the adjustment.
- Make Further Adjustments if Necessary: If the parallelism is still not within the acceptable range, repeat the adjustment process until the desired parallelism is achieved.
Tips and Best Practices
- Regular Maintenance: Regularly inspect and maintain the servo hydraulic press machine to ensure that the pressing plate remains parallel. This includes cleaning the machine, lubricating the moving parts, and checking the alignment of the machine components.
- Use High-Quality Tooling: Invest in high-quality tooling that is designed to work with the servo hydraulic press machine. Poor-quality tooling can cause uneven pressure distribution and affect the parallelism of the pressing plate.
- Follow Manufacturer's Instructions: Always follow the manufacturer's instructions and guidelines when adjusting the parallelism of the pressing plate. The manufacturer's recommendations are based on the specific design and specifications of the machine and will ensure proper operation.
- Train the Operators: Provide proper training to the operators on how to adjust the parallelism of the pressing plate. Make sure that they understand the importance of parallelism and the correct adjustment procedures.
