Sheet metal bending process
Introduction to sheet metal bending principles and equipment
Principle:Sheet metal bending is carried out by placing the metal plate on a bending machine and using the relative movement of the upper and lower molds to plastically deform the plate at the bending radius of the mold, thereby achieving the expected bending angle and shape.
Equipment introduction:Sheet metal bending machines are usually composed of a body, workbench, upper and lower molds, hydraulic system, electrical control system, etc. Among them, the accuracy and wear resistance of the upper and lower molds have an important impact on the bending quality.
Setting and adjusting skills of bending process parameters
Bend angle:Set the bending angle according to product requirements and achieve it by adjusting the mold clearance and hydraulic system pressure.
bend radius: The bending radius affects the deformation degree and stress distribution of the plate, and needs to be reasonably selected according to the plate thickness and material.
sheet thickness:Different thicknesses of plates require different bending forces and die clearances, and equipment parameters need to be adjusted according to the thickness of the plate.
Plate material:Different materials of plates have different elasticity and plasticity, and the bending process parameters need to be adjusted according to the material characteristics.
Common problem analysis and solutions
Incorrect bend angle:It may be caused by improper adjustment of mold clearance, unstable hydraulic system pressure, etc., and relevant parameters need to be checked and adjusted.
Cracks appear at the bend:It may be caused by reasons such as too hard plate material and too small bending radius, so it is necessary to replace the appropriate plate or adjust the bending radius.
Scratch on the surface of the plate:It may be caused by rough surface of the mold and improper placement of the plate. It is necessary to keep the mold clean and smooth and ensure that the plate is placed correctly.
Application examples of sheet metal bending
Home appliance manufacturing:For example, the casings of home appliances such as refrigerators and washing machines are often manufactured using sheet metal bending processes.
Automobile manufacturing:In the manufacturing process of automobile bodies, doors and other parts, sheet metal bending process is widely used.
Architectural decoration:For example, in the manufacture of building decoration materials such as metal doors and windows and metal partitions, sheet metal bending technology is often used.
Aerospace:In the aerospace field, sheet metal bending process is used to manufacture metal parts for aircraft, rockets and other aircraft.
