Machine for loading rivet and joining point inside punching die

Abstract

The invention relates to the riveting machine technical field, in particular to a top rivet feeding contact machine in a punching die. A slide block is provided with a curved hook which is adjacent toa guide rail, a press plate is provided with a stopper which is pressed against an inner side of the curved hook, a riveting punch is movably arranged on a top plate by a second elastic element and right above the curved hook, a riveting needle is correspondingly arranged right below the curved hook, and movably sleeved in a lift pin, and the lift pin is fixed on a bottom plate; the slide block is provided with the curved hook which is adjacent to the guide rail, a rivet enters the curved hook through the guide rail, and is tightly hooked by the curved hook, the press plate is provided with the stopper which is pressed against the inner side of the curved hook, so when the curved hook moves to the right, the stopper stops the rivet, the rivet is separated from the curved hook and falls ina material belt hole to realize top rivet feeding and accurate positioning; the riveting punch is tightly pressed against the riveting needle to complete the riveting; moreover, the machine also hasthe advantages of dense and firm riveting contacts, high working efficiency and the suitability for mass production.

Description

Technical field: [0001] The invention relates to the technical field of riveting machines, in particular to a rivet joint machine for feeding upwards in a stamping die. Background technique: [0002] Rivet connection is a commonly used fixed connection method in mechanical processing. Since the stamping equipment does not have a rivet feeding device, the process of riveting the rivet on the connecting piece in the stamping equipment is usually done manually after placing the rivet at a predetermined position. Press riveting. On the one hand, this method increases the labor intensity of the operators and reduces the work efficiency. On the other hand, there are certain potential safety hazards in safe operation. The existing riveting machine feeds the rivet from the bottom of the material belt hole of the material belt, which leads to inaccurate positioning of the rivet, loose combination, weak work efficiency, and low working efficiency, which is not suitable for large-scal...
