Bending parts

Bending parts refer to components formed through the bending process,that is,parts obtained by deforming plate,pipe,or bar materials into a certain curvature,shape,and size under the action of external force.They are widely used in various industries.Here is a detailed introduction:

Types

Classified by bending angle:They can be divided into acute-angle parts,right-angle parts,obtuse-angle parts,etc.

Classified by bending radius:They include sharp-bend parts,semi-bend parts,and full-bend parts.

Classified by material:There are metal bending parts,plastic bending parts,wooden bending parts,etc.

Manufacturing Processes

Press Bending:It is the most commonly used bending method,usually carried out on a mechanical press or hydraulic press.The mold is used to apply pressure to the material to make it bend.

Roll Bending:It uses a rolling machine to bend the material.The metal is passed between the rollers,and the rollers gradually apply pressure to shape the material into the desired curvature.This method is suitable for manufacturing cylindrical,conical,and other shapes.

Draw Bending:For bending parts with higher precision requirements,larger length and curvature radius requirements,and smaller transverse dimension requirements,draw bending can be carried out on a special draw bending machine.During draw bending,the entire thickness of the plate is subjected to tensile stress,so the springback deformation after unloading is small,and the precision is easy to ensure.

Application Fields

Automotive Industry:Many components in automotive bodies,chassis,and engines,such as exhaust pipes,fuel lines,and chassis parts,are bending parts.

Home Appliance Industry:The shells and internal structural parts of refrigerators,washing machines,air conditioners,and other home appliances often need to be processed by bending technology.

Aerospace Industry:Components such as aircraft fuselages,wings,and rocket bodies require high-precision bending parts to ensure the performance and safety of the aircraft.

Furniture Industry:As shown in the curved components of chairs,sofas,headboards,etc.,bent plywood or metal bending parts are often used to achieve an ergonomic and aesthetically pleasing design.

Quality Control Points

Control of Bending Radius:Ensure that the bending radius meets the design requirements,and it can be detected by a radius measuring instrument.

Control of Bending Angle:Use an angle measuring instrument to detect to ensure that the bending angle is accurate.

Control of Surface Finish:The surface of the bending part should be smooth,without burrs,cracks,and other defects,and surface treatment such as painting and electroplating can be carried out as needed to improve corrosion resistance and appearance.
