[0002] In the assembly of many components, one of the connection methods is riveting connection, and the implementation of riveting is divided into hot riveting and cold pressing. The mushroom head is formed by cold pressing to realize riveting, or the mushroom head structure is formed by hot melting at the head of the rivet to realize riveting. The traditional hot riveting machine generally adopts a pressing plate structure. The heating plate transmits heat to the hot riveting head by electric heating method. The hot riveting head heats the riveting column to make it melt, and then blows air to cool and solidify to form a riveting head to fix the product. This way is to heat the hot riveting head by direct contact with the hot riveting column. There is also a hot air riveting press in the prior art, which realizes the melting of the hot riveting head by blowing hot air to the hot riveting column. This way is not in direct contact with the hot riveting column, so it is a non-contact hot riveting machine.

[0003] For the non-contact hot riveting machine, the riveting head is generally a hollow pipe structure. Hot air is blown out from the inside of the riveting head to the head of the hot riveting column to make it melt at high temperature, and then the mushroom head structure is formed by the cold pressing head to realize riveting.

[0004] The cold pressing die set for the hot air riveting press needs to be replaced frequently due to long-term wear and tear. When replacing the cold pressing head in the prior art, the entire cold pressing die set needs to be detached from the driving part, and then the elastic parts, cover plates and other parts need to be detached. Since the installation height precision of the cold pressing head is particularly high, the equipment needs to be started multiple times to detect whether the cold pressing head is installed in place each time the cold pressing head is replaced.

The cold pressing head mounting bases are elastically and floatingly arranged on the die set mounting seat, and the cold pressing heads are installed on the cold pressing head mounting bases in a detachable manner.

[0008] Further, the module mounting seat is provided with a plurality of mounting holes penetrating through the upper and lower surfaces, the mounting holes are stepped holes with the upper part being larger and the lower part being smaller, the cold pressing head mounting base is movably arranged in the mounting hole, and a compression spring is arranged in the mounting hole to hold the cold pressing head mounting base downward.

[0009] Further, the cold pressing head mounting base axially comprises a guide rod part, a convex ring and a main body rod part from top to bottom, the compression spring is sleeved on the guide rod and holds the surface of the convex ring at the bottom, the convex ring is limited in the lower limit position by cooperating with the stepped surface of the mounting hole, and the main body rod part of the cold pressing head mounting base extends out of the lower surface of the module mounting seat.

[0010] Further, the upper surface of the module mounting seat is provided with a cover plate to shield the mounting hole.

[0011] Further, a clamping plane for clamping and stopping rotation is symmetrically arranged on the circumferential surface of the main body rod part.

[0012] Further, the top of the cold pressing head is a threaded rod, and the bottom of the cold pressing head mounting base is provided with a threaded hole matched with the threaded rod.

[0013] Further, the cold pressing head and the cold pressing head mounting base are connected together in the form of a buckle structure.

[0014] Further, the cold pressing head and the cold pressing head mounting base are connected together in the form of a pin hole.

[0015] Further, the module mounting seat is provided with a plurality of waist-shaped mounting holes penetrating through the upper surface.
