In the field of sheet metal processing, precise control of bending angle is a key link to ensure product quality. Whether it is making exquisite electronic product shells or large mechanical equipment parts, the precise bending angle is directly related to the final performance and appearance of the product. For inkjet printer manufacturers, the bending accuracy of sheet metal parts such as the equipment shell will also affect the overall quality and market competitiveness of the product. Next, let's take a closer look at the precise control method of bending angles in sheet metal processing.

Choose the right bending equipment

Bending machines are the basis for precise control of bending angles. Different types of bending machines differ in accuracy, stability and function. For example, an electro-hydraulic servo CNC bending machine can accurately and stably adjust metal sheets to ensure that the tool moves stably and evenly during the bending process. This type of equipment uses a digital control system to accurately control the movement of the slider according to the preset program, thereby achieving precise control of the bending angle. In actual operation, the operator only needs to enter the accurate bending angle value on the control panel, and the equipment can complete the bending action according to the instructions, greatly improving the accuracy of the bending angle.

Adapt the right bending die

The bending die is closely related to the accuracy of the bending angle. Different die are required for different sheet metal thickness, material and bending shape requirements. The design and manufacturing accuracy of the die directly affects the bending effect. For example, for some high-precision sheet metal bending tasks, special die that has been precisely processed and strictly tested needs to be used. These die have high dimensional accuracy and can provide uniform pressure to the sheet metal during the bending process to ensure the consistency of the bending angle. Inappropriate die may cause uneven force on the sheet metal during bending, resulting in deviation in the bending angle and affecting product quality.

Accurately control process parameters

The setting of bending process parameters has an important influence on the bending angle. These parameters include bending pressure, bending speed, bending compensation value, etc. Before bending the sheet metal, these parameters need to be accurately calculated and set according to factors such as the material, thickness and bending radius of the sheet metal. For example, thicker sheet metal usually requires greater bending pressure, while harder sheet metal needs to adjust the bending speed appropriately to avoid deviation in the bending angle due to excessive pressure or too fast speed. At the same time, setting the bending compensation value reasonably can effectively compensate for the rebound of the sheet metal during the bending process, so that the final bending angle is closer to the design requirements.

Standardized operation process and key points

The operator's skills and operating specifications also have a great impact on the accuracy of the bending angle. When operating the bending machine, it is necessary to strictly follow the operating procedures. First, it is necessary to ensure that the sheet metal parts are accurately positioned in the mold to avoid bending angle errors caused by positioning deviations. Secondly, during the bending process, pay close attention to the operating status and bending conditions of the equipment and adjust the parameters in time. For example, when a slight deviation in the bending angle is found, the bending pressure or speed can be fine-tuned according to the actual situation. In addition, regular maintenance and maintenance of the equipment to ensure that the equipment is in good operating condition is also an important measure to ensure the accuracy of the bending angle.
