Hydraulic shearing machines play a crucial role in various industries, enabling precise cutting of materials. Adjusting the back length, setting parameters for CNC shearing machines, and addressing shearing size deviations are essential tasks in ensuring optimal performance. Here, we’ll explore these aspects and provide insights into effective adjustments.
How to Adjust the Back Length of A Hydraulic Shearing Machine
To adjust
For the length adjustment of the shearing machine, the specific operating steps are as follows:
1. First, you need to remove the blade and clean it. Because the blade can be used on four sides, you need to choose a better side for installation. Also, check the blade for horizontal and vertical straightness.
2. The lower blade can be adjusted, but the key to adjustment lies in the upper blade. The upper blade is usually fixed, so we need to adjust the blade gap of the shearing machine by adjusting the lower blade.
3. In order to adjust the fixed length of the trigger, we need to find the two screws on the left and right of the lower blade that widen the gap, and the set screws that push the lower blade to narrow the gap. These screws are usually located on the inside, while the upper blade’s locking backup nut is on the outside.
4. Loosen the four left and right bolts on the lower blade table, and then manually turn the upper blade to the appropriate shearing height. The operator starts the adjustment in the blanking area of the shearing machine.
5. Use a feeler gauge to make a rough adjustment to 0.5 mm starting from the unengaged parts of the upper and lower blades of your left hand. Then, manually turn the blade up to the middle position and continue coarse adjustment to 0.5 mm. Finally, manually turn the blade up to the position where the upper and lower blades are not disengaged on the right side, and also adjust it roughly to 0.5 mm.
6. After the above steps, we can get a preliminary cutting size. Next, we need to make precise adjustments to this size. This can be achieved by repeating the process of steps 5 and 6.
It should be noted that when adjusting the length of the shearing machine, the factors of the tool and steel plate material should be taken into consideration, and adjustments should be made on a reasonable basis. Once adjustments are completed, settings should be saved to avoid confusion when adjusting again.
How to Adjust the Parameters of CNC Shearing Machine
Adjusting parameters on a CNC shearing machine is a critical task to ensure precise cutting and optimize performance. Here is a detailed guide on the steps involved in adjusting various parameters for efficient operation:
Accessing the CNC Shearing Machine Interface:
Begin by entering the CNC shearing machine interface using the following steps:
- Press the “Open/Close” button on the CNC shearing machine panel to access the operation interface.
Navigating to the Counting Setting Interface:
Once in the operation interface, proceed to the counting setting interface:
- Select “Counting Settings” to access the counting setting options.
Adjusting the Count Value:
Follow these steps to modify the count value:
- Check the current count value in the count setting interface.
- Utilize the “Up/Down” buttons to increase or decrease the count value.
- After making adjustments, press the “OK” button to save the new value.
Verifying the Count Value:
When working with metal materials, it is crucial to confirm that the count value on the display has been updated and aligns with expectations.
Additional Parameters for Adjustment:
In addition to counting settings, there are several other parameters on the CNC shearing machine that can be adjusted to enhance performance:
- Tension Setting: Adjust tension based on the thickness and hardness of the material to ensure precise shearing accuracy.
- Cutting Angle Setting: Set different cutting angles as needed to achieve various cutting effects.
- Knife Edge Gap Setting: Reasonably adjust the knife edge gap to improve overall cutting quality.
- Backcut Settings: Modify backcut depth and angle according to material properties.
- Bedding Settings: Add suitable bedding to protect the cutting edge and material during the cutting process.
- Cutting Length Setting: Set the cutting length according to specific project requirements.
- Automation Settings: Configure the degree of automation on your CNC hydraulic shearing machine to enhance efficiency and overall shear quality.
It’s important to note that specific adjustment methods and precautions may vary depending on the device model and usage environment. For precise guidance, consult the device manual or seek professional assistance when making adjustments. Regularly updating and fine-tuning these parameters contribute to the machine’s optimal performance and longevity.
How to Adjust the Shearing Size Deviation
Addressing shearing size deviations involves considering various factors:
- Lack of parallelism between the back baffle and the lower knife.
- Inconsistency between actual and programmed values, requiring compensation or correction.
- Deviations due to changes in the straightness of the backsplash.
- Non-perpendicular positioning of side positioning and the lower knife.
To resolve size deviations:
- Adjust the parallelism between the rear baffle and the lower knife.
- Compensate or correct the X-axis reference point.
- Adjust the straightness of the rear fender cautiously, confirming repeatedly by experienced individuals.
- Correct the perpendicularity between side positioning and the tailgate.
Ensure these adjustments are made considering specific model and usage requirements. For detailed guidance, refer to the device manual or seek professional assistance.
In conclusion, addressing these hydraulic shearing machine issues enhances precision, efficiency, and overall performance. Regular maintenance and adherence to adjustment protocols are crucial for optimal results.
