Detailed methods and applications of sheet metal bending
First. Manual bending:
For small quantities and simple shapes of sheet metal parts, manual bending tools can be used for bending. This method is highly flexible, but the precision and efficiency are relatively low. When operating, workers need to use the appropriate bending tools according to the requirements of the drawings, and bend the sheet metal parts step by step until the desired angle and shape are achieved.
Secondly. Mechanical bending:
Mechanical bending is carried out by bending machine, which is suitable for processing sheet metal parts with large quantity and high precision requirements. Bending machine through the relative movement of the upper and lower moulds, sheet metal parts for fast, accurate bending. The shape and size of the dies can be customised to meet the bending requirements of different angles and shapes. During the mechanical bending process, attention needs to be paid to the selection and adjustment of the moulds, as well as the positioning and clamping of the sheet metal parts, in order to ensure the accuracy and stability of the bending.
Third. CNC bending:
CNC bending is carried out using CNC bending machines with a higher level of automation and intelligence. CNC bending machine automatically completes the bending process of sheet metal parts through pre-programmed bending procedures. Workers only need to place the sheet metal parts on the worktable of the bending machine and set the relevant parameters to achieve automatic bending. CNC bending is characterised by high precision, high efficiency and high flexibility, and is suitable for processing sheet metal parts with complex shapes and high precision requirements.
Fourth. Mould bending:
Mould forming bending is a method of bending sheet metal parts through pre-made moulds. The shape and size of the mould matches the sheet metal part to be bent, and the worker only needs to place the sheet metal part in the mould and apply appropriate pressure to achieve fast and accurate bending. Mould forming bending is suitable for processing large quantities and complex shapes of sheet metal parts, which can improve production efficiency and processing accuracy.
Fifth. Heating bending:
For some sheet metal materials that are difficult to bend directly, such as stainless steel, high carbon steel, etc., the heating bending method can be used. Before bending, the sheet metal parts are first partially heated to soften them before bending. Heating can reduce the hardness and strength of the material, making it easier to bend. Heating bending needs to pay attention to the control of heating temperature and time, as well as the cooling treatment after bending, in order to avoid material deformation or cracking.
