Description

Technical Field

[0002] The riveting machine is a new type of riveting equipment developed based on the principle of cold rolling. It refers to mechanical equipment that can rivet objects together with rivets. It solves the problem that some sheet metal parts cannot be directly placed on ordinary sloped cast steel machinery for riveting after bending. In the daily work of operators, the working principle of traditional riveting machines is to manually place the rivets on the base, press the riveting switch on the top, and the top riveting column will drop a certain distance to combine the rivet with the sheet. After the riveting technology, the sheet needs to be taken out manually, and then the rivets are placed on the base and operated in sequence.

[0003] The riveting machine is suitable for the connection of steel plates, stainless steel plates, aluminum plates and non-metallic interlayers. When riveting, the operator needs to hold the plate, align the rivet holes on the plate with the rivet head, drop the rivet head, rivet studs or rivets on the holes, then lift the plate, replace the rivet holes and rivet again. However, this riveting method requires labor and has high requirements for operators, poor positioning accuracy, low production efficiency, and the rivet head is prone to cause accident risks to the operator during riveting. Therefore, it is necessary to propose an automatic positioning riveting machine to solve the above problems. Utility Model Content
