Description

Technical Field

[0001] The utility model belongs to the technical field of rivet guns, and in particular relates to a transmission structure of an electric rivet gun. Background Art

[0002] Rivet guns, also known as rivet guns, are mainly used for riveting aluminum, iron, and stainless steel plates. Stainless steel / alloy steel rivet nozzles. Mainly pneumatic rivets, the gun rivet pulling speed is fast. Hydraulic structure, strong rivet pulling force. Rivets are a type of rivet used for single-sided riveting, but must be riveted with a special tool, a rivet gun. During riveting, the rivet core is pulled by a special rivet gun to expand the rivet body and play a riveting role. This type of rivet is particularly suitable for riveting occasions where it is inconvenient to use ordinary rivets (riveting must be done from both sides), so it is widely used in construction, automobiles, ships, aircraft, machinery, electrical appliances, furniture and other products. Among them, open-type flat round head blind rivets are the most widely used, countersunk head blind rivets are suitable for riveting occasions where the surface needs to be smooth, and closed-type blind rivets are suitable for riveting occasions that require higher loads and certain sealing properties.

[0003] The existing rivet guns mainly use pneumatic structures to pull rivets, and the pneumatic structure generally has a faster rivet pulling speed, but the pneumatic structure must ensure sufficient air pressure. If the air pressure is insufficient, the rivets may not be pulled apart, or they may need to be pulled apart repeatedly. Pneumatic rivet guns are mainly used in specific places with air pumps, and have certain limitations. Electric rivet guns do not have this limitation and can be used in any place. The problem addressed by this device is how to further improve the success rate of pulling rivets apart. Utility Model Content
