The key interface modes commonly used by sheet metal processing plants are riveting bonding, hole drawing riveting, tox riveting, bonding, external thread connection, electric welding, etc

1. Riveting

This kind of rivet is often called a rivet, the two plates are riveted together by a rivet, which is called pull riveting.

2. Hole drawing riveting

One of the parts is a hole drawing, the other part is a counterbore. After riveting, it becomes a butt joint which is difficult to disassemble. Advantages: the counterbore with mutual cooperation between the two parts has the function of precise positioning. The riveting compressive strength is high, the high efficiency of grinding tool riveting is also higher.

3. Tox riveting

After a simple die base will be inserted into the cavity. Under the further working pressure, the material in the cavity will be outward. The effect will produce a circle to point point without light burr, it is easy to damage its corrosion resistance. Even the parts with coating spraying layer on the surface can also store the original anti-corrosion treatment characteristics, Because the coating paint film are also with the deformation theme activities. Raw materials are squeezed to both sides, squeezed into the parts close to the die side, then form a small tox butt circle.

4. A method of bonding by using adhesive to connect the required joint as the adhesive.

5. External thread connection external thread connection LAN installation is very easy, disassembly is convenient, practical operation is simple other advantages, common in removable steel frame structure connection, it can be divided into screw connection anchor bolt connection.

6. Riveting riveting is a way to connect the parts components of metal components with rivets. There are many types of rivets. The common rivets are closed round mouth core pulling rivet, closed type countersunk head core pulling rivet, open mouth round mouth core pulling rivet open mouth type countersunk head core pulling rivet.

7. Electric welding welding -- it is the processing method of partial overall heating of sheet metal parts plastic deformation of welded parts, heating plastic deformation separately to complete the connection. It can be divided into: electric arc welding, steam maintenance arc welding, laser welding, section welding touch welding. The main workers of our factory choose gas shielded welding contact welding.

1.1 steam body maintenance arc welding: when carrying out steam maintenance arc welding, the electric level arc area electric welding bath are under the maintenance of steam body, argon is selected to weld metal oxides reference materials in Meiyu weather. It can be welded in all indoor space parts, the whole forming process of electric welding can be observed by human eyes, the production manufacturing efficiency can be adjusted.

1.2 touch welding the welding process of butt weld produced by heating the connection position instantly pressurizing the welded part under the condition of melting non melting during touch welding, which can be divided into butt welding, welding seam welding.
