Changes in conventional sheet metal processing

The conventional Shanghai sheet metal processing process is selected from: shear-punch-bend-welding process or flame plasma incision-bending-welding process. In the face of multiple categories, small batches, customized, high quality, short delivery orders, it shows obvious incompatibility. The laser cutting process emerges as an alternative to “shear-crush” and is characterized by flexibility and flexibility. Most people also think that their cost is high. Therefore, it is often used in the manufacture of shaped (or chaotic) workpieces and samples (single or very small batch). However, as small-volume manufacturing becomes more and more timely, the demand for laser cutting is also increasing.

When looking at the new sheet metal processing technology from the beginning: laser cutting-bending-welding/rivet welding, because of the high flexibility and high precision of laser cutting, the 3D planning technology is sophisticated and comprehensive, users can re-plan, new Benefit from the process, and then reach the requirements of reducing costs and shortening the construction period. So the new sheet metal process begins with planning: planning laser cutting, bending, welding/welding. Here are a few examples to illustrate the characteristics of the new process.

1) Under the traditional process, the workpiece consists of several parts. Now, once the cut is completed, the bend is over. Reached the process of reducing the process, shortening the construction period and reducing the cost

2) Under the traditional process, special fixtures for welding equipment. Nowadays, the process of using similar woodworking boring parts is adopted, the positioning is accurate, the time is saved, the welding fixture is simple, and the product deformation is small. Arrived to shorten the construction period, reduce the cost, and improve the quality of the intention.

3) The multi-bending process has been widely used in the domestic box manufacturing industry. The advantage is that the traditional reinforcements are eliminated. It has its own locality in planning and craftsmanship. Then arrive at the high quality of the product, the intention to create low cost. Under the practical process, it is necessary to cooperate with spot welding.

4) Using the laser to cut the slits with high precision, one cut (with micro-join), four times of bending, and four workpieces. Breaking through the planning thinking under the traditional craft, it has reached the goal of shortening the construction period and reducing the cost.

5) Because the 榫 structure is used and the workpiece is bent and the spot welding process is completed, the whole process can be completed. The workpiece is small in deformation and does not need to be shaped or polished before spraying.

Because of the characteristics of the new process, advanced sheet metal equipment software support and planning, laser cutting process, bending process. It supports two-dimensional parts planning, pipe-like parts planning, bending workpiece planning (only supporting Baicha's bending machine), and three-dimensional graphics development. The CNC program is transferred to the designated machine via a standard computer network.
