Automatic feeding device for pressing rivet nut

Abstract

The invention relates to an automatic feeding device for a pressing rivet nut. The automatic feeding device for the pressing rivet nut automatically completes the feeding process, meanwhile is simple in structure and high in working efficiency, and does not have the material clamping problem even when working for a long time uninterruptedly. The automatic feeding device for the pressing rivet nut comprises a hopper mechanism, a flow distribution integrating and separating mechanism and a pressing rivet mechanism, wherein the hopper mechanism comprises a hopper, a vibration unit, discharging devices and a circulation material returning device, the vibration unit comprises a sliding rail, a motor and a connecting rod, the discharging devices are in a strip shape and are arranged on the two sides of the hopper respectively, first discharging holes and second discharging holes are alternately formed in the discharging devices in a spaced mode, the circulation material returning device is arranged at the bottom of the hopper, the flow distribution integrating mechanism comprises a first flat guiding tube, a second flat guiding tube, an integrating and separating device and a feeding flat guiding tube, the bottom end of the first flat guiding tube is rotated by 18 degrees and then is communicated with the top end of the integrating and separating device, the bottom end of the second flat guiding tube is communicated with the top end of the integrating and separating device, the top end and the bottom end of the feeding flat guiding tube are communicated with the bottom end of the integrating and separating device and the pressing rivet mechanism respectively, and the pressing rivet mechanism is used for pressing the pressing rivet nut into a reset hole in a workpiece.

Description

technical field [0001] The invention relates to a component of a riveting machine, in particular to an automatic feeding device for a riveting nut. Background technique [0002] The rivet nut is a kind of fastener used in sheet metal, thin plate, chassis, and cabinet. The rivet nut is pressed into the preset hole of the workpiece such as the thin plate by a press, and the periphery of the hole is plastically deformed, so that The rivet nut is tightly fixed on the thin plate, so that an internal thread structure capable of effectively fixing the screw is formed on the thin plate. In the prior art, people usually put the rivet nut manually into the preset hole of the thin plate, which not only brings hidden dangers to the personal safety of the operator, but also reduces the production efficiency; in addition, there are still Some self-feeding equipment for rivet nuts, but these devices usually have a complex structure, and there are problems such as material jams during the ...
