Detailed steps for adjusting the bending tooling to ensure the consistency of the angles at the ends of long sheet metal parts

When the angle of the ends of a long sheet metal part being bent is not consistent, the detailed steps for adjusting the bending tooling can be summarised as follows:

Initial Inspection:

Carefully inspect the die for signs of wear or damage, especially on the parts that come into contact with the sheet metal part. Make sure that the top and bottom surfaces of the mould are flat and free from unevenness.

Adjust the die clearance:

The size of the die clearance directly affects the bending angle. Depending on the material and thickness of the sheet metal part, precisely adjust the die clearance to ensure that it is within the appropriate range. For example, for sheet metal parts made of a specific material, it may be necessary to set a specific clearance value based on material manuals or empirical values.

Check the bending force:

The magnitude and distribution of the bending force is also an important factor in angle consistency. Ensure that the bending force provided by the bending machine is evenly distributed, with no localised excesses or deficiencies. If you find that the bending force is not uniform, you can adjust the pressure of the bending machine or the parameters of the hydraulic system appropriately.

Adjust the intermediate block:

For bending of long sheet metal parts, the position and height adjustment of the intermediate block is particularly important. Ensure that the contact surface between the intermediate block and the mould is flat, and the height is moderate to avoid deformation or offset in the bending process.

Optimise the positioning of sheet metal parts:

Ensure that sheet metal parts are accurately positioned on the bending machine. Use positioning pins, positioning blocks and other auxiliary tools to ensure that sheet metal parts are accurately placed during each bending to avoid inconsistent angles due to inaccurate positioning.

Fine tuning and testing:

After making the above adjustments, carry out a small batch of test bending to check whether the bending angles are consistent. If any inconsistency is found, fine-tuning can be carried out according to the results of the trial bending until a satisfactory result is achieved.

Through the above steps, the bending mould can be adjusted gradually to ensure the consistency of the angle of the two ends of the long sheet metal parts. During the adjustment process, it is necessary to observe carefully, adjust patiently and respond flexibly according to the actual situation.
