Description

Technical Field

[0001] The utility model relates to the technical field of riveting devices, in particular to an automatic feeding double-pump riveting device. Background Art

[0002] Riveting machine (also known as riveting machine, rotary riveting machine, riveting machine, rolling riveting machine, etc.) is a new type of riveting equipment developed based on the principle of cold rolling, which 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 slope cast steel machinery for riveting after bending. Riveting machines are mostly used for the connection between plates and rivets. Special rivet nuts are generally used. Through pressure extrusion, the nuts and screws are perfectly buckled with the plates. Riveting machines are needed in the production process of chassis cabinets, auto parts, air duct valves, and washing machine casings.

[0003] The existing automatic feeding double pump riveting device (publication number: CN220216614U) has at least the following disadvantages:

[0004] When the above patent is in use, the staff stands in front of the base and puts the workpiece into the corresponding placement slot. After the workpiece is placed, the dual-axis motor is started, and the dual-axis motor drives the feed tray to rotate. The feed tray rotates to transport the workpiece to the bottom of the pressure head, thus realizing automatic feeding. When the above patent is in use, the operator is required to manually put the materials on the feed tray one by one each time, and then take them out one by one after processing is completed. During batch production, manual material placement and material collection increases the labor intensity of the operator and affects production efficiency. Utility Model Content

The driving arm 17 drives the slider 14 to move to the far left end through the driving groove 20 and the second driving column 19. At this time, the slider 14 pushes the stopper 13 to move to the far left end. The outer surface of the slider 14 is provided with a groove, and the workpiece 11 slides into the inside of the groove, and then drives The motor 22 reverses to the initial point, and drives the workpiece 11 to move to the right below the rivet head 3 through the slider 14, and uses the lifting mechanism inside the rivet head 3 to press the workpiece 11 down for rivet processing. Through this device, there is no need for the operator to manually pick up the workpiece 11 every time, which greatly reduces the operator's workload during mass production. After the processing is completed, the turntable 16 is driven by the driving motor 22 to rotate 90° in the direction close to the blanking hole 21, so that the driving arm 17 drives the slider 14 to move close to the blanking hole 21, and the slider 14 drives the riveted workpiece 11 to move to the position of the blanking hole 21, so that the workpiece 11 falls from the blanking hole 21 into the collection box below, which is convenient for subsequent processing.
