Description

Riveting machine with protection function Technical Field The utility model relates to the technical field of riveting machines, in particular to a riveting machine with a protection function. Background The chinese patent application of application number 201720680511.1 discloses a riveter, including frame, conveying structure and stamping structure, the upper end of frame is equipped with the hopper, the lower extreme of hopper with conveying structure connects, conveying structure's lower extreme with stamping structure meets, stamping structure includes the ram rod, the ram rod lower extreme is connected with the rivet head through protection architecture, protection architecture includes the protective housing, the protective housing with be connected with the swivel nut between the ram rod, be equipped with the sphere seat in the protective housing, the top of sphere seat is equipped with the main shaft, the inside of sphere seat is equipped with rotating member. In the above technical scheme, through setting up the protective housing in the bottom of punching press pole, make the protective housing along with the synchronous removal of drift of riveter, and prevent that the operator from touching the drift of riveter through the surface that the protective housing is slope form, but in above technical scheme, the drift that exposes the protective housing still needs to be contacted with the work piece that waits to punch that is located on the riveter base when the riveter punching press, and along with the synchronous quick decline of drift of riveter the protective housing bottom still exist the possibility that contacts with the operator's hand, the operator is when operating the riveter, the space that forms between protective housing bottom and the work piece upper end that waits to punch is pressed with the hand pressure of operator easily, therefore, protect the technical problem that still need solve in the prior art at the end of the drift stroke of riveter. Disclosure of utility model The utility model aims to provide a riveting machine with a protection function, which can protect at the tail end of a punch stroke of the riveting machine. In order to achieve the above purpose, the utility model discloses a riveting machine with a protection function, which comprises a frame and a base arranged on the frame, wherein one end of the base along the length direction of the base is positioned below a punch of the riveting machine, the other end of the base is provided with an electric push rod module for conveying rivets to the lower end of the punch of the riveting machine along the length direction of the base, one end of the base, which is close to the punch of the riveting machine, is provided with a sunken step surface as a processing station, the upper end of the base, which is close to the processing station, is provided with a protection mechanism, the protection mechanism comprises a protection ring fixedly arranged at the upper end of the base, the protection ring is positioned right below the punch of the riveting machine and above the processing station, and the distance between the bottom surface of the protection ring and the upper surface of the processing station is smaller than the standard thickness of a human hand.
