At least two sets of air-bearing table assemblies are provided, with their bottom sides supported on a plane by a frame. A platform is provided between the two sets of air-bearing table assemblies, on which the feeding assembly is mounted. The feeding assembly has grippers and support arms, with the support arms mounted on the platform and grippers installed at their ends. The air-bearing table assembly is composed of multiple air-bearing table modules assembled through a splicing structure. Each air-bearing table module includes an upper shell, an air supply chamber, an air supply pipe, and an air-bearing table unit.

One side of the air supply chamber is connected to a pumping device via an air supply pipe, and several quick-connect interfaces are distributed on the air supply chamber. This invention uses a roller-type air-bearing table. Compared to ball bearings, rollers have lower rolling resistance, resulting in lower contact pressure and resistance between the roller and the sheet metal, making it less likely to form scratches on the sheet metal surface.

Description

Technical Field

[0001] This invention relates to the field of sheet metal feeding, specifically to a bending center feeding platform using an air-bearing table. Background Technology

[0002] Sheet metal processing is a manufacturing process, and there is still no complete definition for it. According to a definition in a foreign professional journal, it can be defined as: sheet metal processing is a comprehensive cold working process for thin metal sheets (usually less than 6mm), including shearing, punching / cutting / combined cutting, bending, riveting, splicing, and forming (such as car bodies). Its significant characteristic is that the thickness of the same part is consistent. The processing of metal sheets is called sheet metal processing.

[0003] Sheet metal feeding is generally achieved by a feeding platform at the bending center, such as... Figure 1-2 As shown, the bending center feeding platform consists of grippers 1, bullseye brush support plates 3, support arms 5, and brackets 4. The bullseye brush support plates 3 are composed of bullseyes 6, brushes 7, and a base plate 8. During operation, sheet metal 2 is placed on the bullseye brush support plates 3, and the grippers 1 clamp and move the sheet metal 2 for feeding. Because the grippers 1 only clamp the central area of ​​the sheet metal 2, the sheet metal 2 deforms significantly. To ensure the sheet metal remains flat during feeding and prevent it from impacting the bed, bullseye brush support plates 3 are used on both sides to support the sheet metal 2. Bullseyes 6 are arranged on the bullseye brush support plates 3, and soft brushes 7 are laid in the empty areas of the bullseye array. Because the sheet metal 2 is prone to scratches and has high frictional resistance when sliding on the surface of the bullseye 6, it cannot meet the needs of customers with high surface quality requirements. Therefore, ball bearing air flotation platforms have emerged on the market to replace bullseye brushes. However, since the steel balls are in point contact with the sheet metal and the rolling properties of the steel balls are not high, for some sheet metal boards with high surface requirements, the steel balls will form a scratch on the surface of the sheet metal when the board slides over it. Therefore, this invention provides a bending center feeding platform using an air flotation platform. The roller air flotation platform has lower rolling resistance than the ball bearings. The contact pressure and contact resistance between the roller and the sheet metal are also lower, making it less likely to form scratches on the surface of the sheet metal. Summary of the Invention
