| Sheet metal processing in the machinery industry is very heavy today Xiaobian explain in detail under the processing of sheet metal parts, sheet metal surface treatment is also a very important part of the sheet metal processing, because it has to prevent parts health Rust, beautify the appearance of the product and so on. Sheet metal surface pretreatment is mainly to oil, scale, rust, etc., it is prepared for the surface after treatment, and then deal with spray (baking) paint, spray and rust-proof coating, etc. Zhengda Chong Hing machinery to share with you authentic precision sheet metal processing process is as follows; 1.Design and draw the parts of its sheet metal parts, the role is to use the way the paper sheet metal parts of the structure expressed. 2. Draw the expansion plan, that is, a complex structure of the parts developed into a flat piece. 3. Blanking: Blanking There are many ways, mainly in the following ways: a. Shear bed cutting, the use of shear cut out of the expansion plan shape length and breadth size. If punching, chamfering, and then punch punch punching, cut corner forming. Cutting out the structural form of its plate on an iron plate. 4. Flanging tapping; flanging also called pumping hole, is a small base hole pumping into a slightly larger hole, and then tapping on the hole. Doing so increases its strength and avoids sliding teeth. Generally used for thinner sheet metal processing. When the plate thickness is larger, such as 2.0, 2.5 or more thickness. 5. Punch processing; general punching processing punching angle, punching blanking, convex convex package, punching, poking and other processing methods to achieve processing purposes. Its processing requires a corresponding mold to complete the operation. Convex convex package convex package, punch tearing tear forming die. 6. Riveting: riveting often used riveted studs, riveting nuts, riveting screws, etc., the pressure riveting method generally by punch or hydraulic riveting machine to complete the operation, the riveted to the sheet metal parts . 7. Bending: bending is 2D flat parts, folded into 3D parts. Its processing needs a folding bed and the corresponding bending mold to complete the operation. It also has a certain order of bends, the principle of which is the pre-folding that does not interfere with the next knife, and that there is a break in the interference. 8. Welding: Welding is the welding of multiple parts together, to achieve the purpose of processing or welding of single parts seam to increase its strength. The processing side of the general CO2 gas shielded welding, welding, spot welding, robot welding. The selection of these welding methods is based on the actual requirements and materials. |
