Sheet metal bending process details: technical characteristics, applications and operation points
Sheet metal bending process is an important metal processing technology, widely used in aviation, automotive, electronics, home appliances and other fields, used to make sheet metal into parts or assemblies of the required shape and size. The following is a detailed description of the sheet metal bending process:
First. Process Overview
Sheet metal bending process mainly includes the following steps:
1. Material Selection: Sheet metal bending is applicable to a variety of metal materials, such as stainless steel, aluminium alloy, copper and so on. When selecting materials, their mechanical properties and cost factors need to be considered to ensure that the bent parts meet the design requirements.
2. Sheet preparation: according to the drawing requirements, calculate the amount of sheet material (i.e., unfolding length), and cut the material into the required size. Generally, plates with a thickness of 0.5-2mm are used.
3. Scribing and positioning: according to the scribed positioning line, the material will be placed in order and fixed, so as to carry out the subsequent bending operation.
4. Bending: use bending machine or other special equipment, according to the required bending angle and shape, select the appropriate process (such as V-shaped mould bending, U-shaped mould bending, etc.) for bending. In the bending process, you need to reasonably arrange the position and angle of the mould to ensure that the size and shape of the bent part is accurate.
5. Subsequent processing: After the bending is completed, the parts are sanded, polished and other subsequent processing, in order to improve its surface quality and aesthetics.
Secondly. Precautions
1. Material thickness and hardness: greater plate thickness and hardness will increase the bending force and equipment requirements, so you need to choose the right material and equipment according to the specific circumstances.
2. Bending angle control: the need to strictly control the accuracy of the bending angle, which can be achieved by means of adjusting the parameters of the bending machine, the position and angle of the mould.
3. Technical requirements: the operator should be familiar with the operating procedures and safety requirements of the bending machine, master the bending process and operating techniques to ensure the safety and quality of the bending process.
Third. The field of application
Sheet metal bending process has a wide range of applications in machinery and equipment manufacturing, transport manufacturing, construction materials and other fields. For example, in automobile manufacturing, the body, doors and other components need to use sheet metal bending process to produce.
In conclusion, sheet metal bending process is an important metal processing technology with a wide range of application prospects. Through reasonable selection of materials, processes and equipment, strict control of the bending angle and quality requirements, we can obtain high-quality parts to meet the design requirements.
