Manhart 下折弯机加工过程中如何保证板料的精确对位？

Ensuring precise alignment of the sheet metal during the processing of the downward bending machine is a key step in ensuring bending quality and machining accuracy. Here are several key methods to ensure precise alignment of the sheet metal:
1、 Use positioning tools
1. * * Positioning pin, positioning block * *: Before placing the board, positioning tools such as positioning pins or positioning blocks can be used to accurately place the board in the set position. These tools can effectively prevent the movement and misalignment of the board before processing.
2、 Adjust the material blocking mechanism
1. * * Block and support frame * *: Adjust the block and support frame in the material blocking mechanism according to the size and shape of the board to ensure stable support and fixation of the board during processing. This helps to reduce the displacement of the board during the bending process.
3、 Set the rear baffle plate
1. * * Angle Adjustment * *: The rear stop plate is used to constrain the position of the workpiece and needs to be adjusted according to the size and angle of the machined part. By loosening the screws, adjusting the rear baffle to the appropriate angle, and then tightening the screws, it is ensured that the workpiece will not shift during the machining process.
4、 Use backboard
1. * * Placement of materials * *: When performing bending operations, if the length of the material to be processed is short or the processed sheet is thin, it is easy to deform or bend. At this point, a back plate can be used and the metal material to be processed can be placed on the back plate for bending operations, which helps improve the accuracy of the bending position.
5、 Utilize numerical control system
1. * * Programming and parameter settings * *: For CNC downward bending machines, precise control of the position and bending angle of the sheet metal can be achieved through programming. According to the requirements of the workpiece, set reasonable parameters such as bending angle, bending sequence, bending speed, etc. to ensure precise alignment and bending of the sheet metal.
6、 Regular calibration and maintenance
1. * * Equipment Calibration * *: Regularly calibrate the bending machine, including angle calibration, pressure calibration, etc., to ensure the accuracy and stability of the equipment. This helps to reduce equipment errors and improve the alignment accuracy of the board.
2. * * Maintenance Inspection * *: Regularly maintain and inspect the bending machine, such as cleaning, lubrication, fastening, etc., to ensure the normal operation and accuracy of the equipment. This also helps to detect and solve potential problems in a timely manner, ensuring the alignment accuracy of the board.
Through the comprehensive application of the above measures, the downward bending machine can ensure the precise alignment of the sheet metal during the processing, improve the bending quality and processing accuracy.
