Description

Technical Field

[0001] The utility model relates to the technical field of rivet screening and processing, and particularly relates to a screening structure device for a riveting machine. Background Technique

[0002] A rivet is a nail-shaped object used to connect two parts (or components) with through holes and a cap at one end. In riveting, the rivet uses its own deformation or interference fit to connect the riveted parts. There are many types of rivets and they are not restricted in form. Commonly used ones include R-type rivets, fan rivets, blind rivets (drive rivets), tree-shaped rivets, semi-circular head rivets, flat head rivets, semi-hollow rivets, solid rivets, countersunk head rivets, blind rivets, and hollow rivets. These usually use their own deformation to connect the riveted parts. Generally, cold riveting is used for those less than 8 mm, and hot riveting is used for those larger than this size, but there are exceptions. For example, the nameplate on some locks is riveted using the interference fit between the rivet and the hole in the lock body. A riveting machine (also known as a rotary riveting machine, riveting machine, rolling riveting machine, etc.) is a new type of riveting equipment developed based on the principle of cold rolling. It refers to a mechanical device that can rivet items with rivets. Therefore, when a riveting machine processes rivets, it needs to screen the rivets first.

[0003] According to a new type of rivet screening device proposed in the patent with the publication number CN217940959U, which includes a housing. There are a first installation notch and a second installation notch on the housing. A baffle is arranged on the first installation notch, and the end of the baffle is installed on the housing through bolts. A horizontal baffle and a vertical baffle are arranged on the second installation notch, and the ends of the horizontal baffle and the vertical baffle are installed on the housing through bolts. The horizontal baffle is located below the vertical baffle. Therefore, the new type of rivet screening device with the above structure can solve the problems of multi-layer stacking of rivet screening and the inability to screen out rivets with the pattern facing down, which may cause production line failures.

[0004] In the process of screening rivets by the existing riveting machine, the turntable rotates for feeding operation. The rotation of the turntable for feeding easily causes the rivets to jam, resulting in a blocking problem, making it impossible to feed the riveting machine. At the same time, the screening effect of the rivets is reduced, and the working efficiency of the riveting machine is also reduced. In order to solve the above problems, a screening structure device for a riveting machine is proposed. Content of the Utility Model
