The connection methods of sheet metal stamping parts include:; Undercut connection, riveting, welding, screw connection, embedding (expansion connection), etc

undercut connection is a connection method that turns, buckles and compresses the edges of stamping parts and plates. Undercut connection does not need special equipment. It has good compactness and reliable connection. It is commonly used in sheet metal mechanisms with a thickness of less than 1mm, such as iron and copper

riveting is a non detachable connection mode formed by rivets. The riveted structure has the characteristics of uniform force transmission, excellent toughness, good plasticity and easy maintenance, so it is used for the connection of some dissimilar metals and weldable metals (such as aluminum alloy)

welding; When sheet metal stamping parts cannot meet the expected requirements. Two parts are often connected into one part, which is what we often call welding. The common welding methods are argon arc welding, electric welding, gas welding, etc

screw connection is generally used for detachable structure, which is characterized by simple structure, easy assembly and disassembly, low cost, wide application and so on

embedded connection; Is to press screws, studs or nuts into sheet metal stamping parts,. Generally, there is no problem with the embedded studs, because the studs are made. There is a groove above the hexagon head of the studs. When the hexagon head is pressed in, the material on the plate will squeeze into the groove and can be fixed by itself. The screws are different. The screws we select are generally not made and have no extrusion groove. Therefore, when the screws are pressed in, the extruded materials have no place to go. Due to the extrusion of materials, it is difficult to control the perpendicularity between the screws and the sheet metal plane. Therefore, when installing other parts, it is often difficult to assemble. The longer the screw, the harder it is to control. At this time, it is better not to use the embedded form, but to connect directly with screws

common problems and causes of sheet metal stamping parts processing

1 Burr: not all surplus materials are left in the process of punching or corner cutting, and burr occurs under the section of steel plate. When the height of burr is more than 0.2mm based on the section, the iron powder will damage the mold and produce convex and concave

2. Convex concave: the surface of the material is abnormally convex or concave, which is caused by the mixing of foreign matters (iron filings and dust) in the uncoiling line

3. Roller print: caused by foreign matters attached to the cleaning roller or feeding roller (with a fixed pitch). Generally, the foreign matters on the roller print on the sheet can be removed

4. Slip mark: caused by the sliding of the roller, which occurs when it suddenly stops or accelerates

5. Roll crushing may lead to edge wrinkling: the guide roller of the uncoiling line may lead to wrinkling caused by the small gap between the guide rollers on the die, which is caused by the imbalance of roll feeding

6. Scratch: the main reason for the scratch on the part. There are sharp scars on the mold or metal dust falling into the mold. The preventive measures are grinding the scars on the mold and removing metal dust

7. Bottom cracking: the main reason for the bottom cracking of parts is that the material plasticity is poor or the die blank holder ring is pressed too tightly. The preventive measures are to replace the material with good plasticity or loosen the blank holder ring

8. Wrinkles on the side wall: the main reason for the wrinkles on the side wall of the part is that the thickness of the material is not enough (the allowable thickness is thinner if it is relatively small) or the eccentricity occurs during the installation of the upper and lower molds, resulting in large clearance on one side and small clearance on the other side. The preventive measures are to replace the materials and readjust the molds immediately
