Sheet metal bending processing technology in laser cutting, bending, welding/riveting, because of the high flexibility of laser cutting, high precision, sophisticated and extensive THREE-DIMENSIONAL planning technology, users can benefit from the new planning, new process. Then arrive at the requirement of reducing cost and shortening the time limit. So the new sheet metal process starts with planning: planning laser cutting, bending, welding/riveting. The following examples illustrate the characteristics of the new process.
1, under the traditional process, the workpiece is composed of several parts. Now, arrived to cut procedures, shorten the time limit for a project, and reduce the purpose of cost.
2, under the traditional process, a special fixture is configured for welding. Now parts of the use similar woodworking tenon technology, to shorten the period, reduce the cost, and improve the quality of the purpose.
3, because of the use of tenon structure, the workpiece bending cooperation spot welding process, the whole process can be completed. The workpiece deformation is small, no need for shaping and polishing before spraying.
4, multiple bending process in the domestic box manufacturing industry has been more extensive, eliminating the traditional reinforcement. It has its purpose of planning with craftsmanship together locally and then arriving at a product of high quality and low manufacturing cost.
5, the use of laser cutting seam thin, high precision characteristics, a cut, break through the traditional process of planning though, reached the purpose of shortening the construction period, reduce the cost. Due to the characteristics of the new sheet metal welding process, advanced sheet metal processing equipment software support and planning, laser cutting process, bending process. It supports two-dimensional parts planning, pipe parts planning, sheet metal bending workpiece planning, 3d graphics open. And the numerical control program is transmitted to the designated machine through the standard computer network.
The mold
A bending die is used for bending the main tooling, usually bending workpiece shape and size depends on the precision of the die. The higher the precision of the mold, the more accurate the assembly, and the higher the bending precision. In addition, the structure and precision of mold positioning have a great influence on the accuracy of workpiece size.
Plate performance
The influence of the performance of the bending sheet on the quality of the bending parts is mainly manifested in two aspects:
1) In the actual production, we found that even if different batches, and different manufacturers of materials, there will be performance fluctuations, stress and rebound are also different, directly leading to the accuracy of bending parts is not stable.
2) the fluctuation of the thickness of the material within the range of upper and lower tolerances is also the cause affecting the accuracy. Even if the same bending die is used for bending, the size and shape of the workpiece are also different. Thick, bending resistance, small rebound; The small thickness of the rebound is large, affecting the accuracy of the workpiece, and easy to produce warping and bending phenomenon.
process
When the bending process increases, the cumulative error of each process will increase. In addition, the arrangement order before and after the process will also have a great impact on the accuracy. Usually follow the order of first short side after long side, first peripheral side after the middle, first local side after the whole. Should consider the interference between the mold and the workpiece, reasonable arrangement of the bending order, bending order is not invariable, according to the shape of the bending or the obstacles on the workpiece to adjust the processing order.
The influence of workpiece shape and size on accuracy
The deviation of the spring back of the bending parts with asymmetric shape and large shape size will increase obviously.
The main factors affecting rebound
(1) Mechanical properties of materials
The mechanical properties of materials refer to the shear strength, tensile strength, and elongation at the yield point of materials. Due to different types and brands of materials, their mechanical properties are also different, and there are fluctuations with different batches.
The surface quality of the material
Sheet thickness and surface quality have a great influence on spring back. If the surface of the material is uneven, concave, and convex or there is a foreign body, it will produce stress concentration during bending, which has a great impact on the rebound.
