Description

Technical Field

[0001] The utility model relates to the technical field of steel sheet riveting, in particular to a steel sheet riveting device. Background Art

[0002] The production steps of steel sheets involve the production of steel sheet riveting, which is specifically inserting rivets into the inner side of the through holes on the steel sheets and forming the rivets by riveting. It is usually processed by a steel sheet riveting device. After the steel sheets and rivets to be riveted are loaded and riveted, the riveted steel sheets are clamped by a unloading robot for unloading.

[0003] The utility model with publication number CN207372611U proposes a silicon steel sheet riveting machine, including: a press-fitting bracket, an upper press die set, a steel sheet support mechanism, a riveted lower support mechanism, a misalignment detection mechanism and a silicon steel sheet guide mechanism. The steel sheet support mechanism is arranged above the riveted lower support mechanism and is connected to the press-fitting bracket through a linear bearing. The upper press die set includes a cylinder die set, an upper press die set, an upper press floating die set, a press-fitting switching device, a riveted pressure head die set and a silicon steel pressure head die set. However, when performing riveting processing on steel sheets, the steel sheet needs to be accurately positioned when it is loaded onto the rivet so that the rivet can pass through the through hole on the steel sheet. Generally, the steel sheet is simply positioned and then placed on the top of the rivet. At this time, the rivet passes through the through hole on the steel sheet or makes large-surface contact with the through hole on the steel sheet. In this way, the rivet can be automatically riveted to the steel sheet under the action of riveting pressure during riveting. However, if the steel sheet has a large deviation during the positioning process, the through hole on the steel sheet and the rivet are seriously deflected. In this way, even if the riveting structure is used for riveting, the rivet cannot pass through the inside of the through hole. At the same time, in the process of the bottom of the steel sheet being lifted upward for a distance by the rivet, due to the position deviation of the steel sheet, the deflected steel sheet cannot be stably clamped and unloaded by a conventional steel sheet unloading fixture. Therefore, a steel sheet riveting device is proposed to solve the above problem. Utility Model Content

The processing turntable 31 continues to rotate and moves the supporting seat 32 to the pressing device 7. The pressing device 7 completes the riveting process of the steel sheet 10. After the riveting is completed, the steel sheet 10 continues to follow the supporting seat 32 to move to the unloading device 4, and is clamped and unloaded by the clamping robot 41, thereby completing the automatic riveting process of the steel sheet 10. By arranging the support seat 32 to rotate with the processing turntable 31 between the four stations for processing, the steel sheet 10 can be loaded, riveted and unloaded at the same place, which is convenient for maintaining the processing status of the steel sheet 10 and on-site equipment.

[0056] The pressing device 7 includes a riveting head 71 that is slidably arranged relative to the machine base 1, and the riveting head 71 slides in a direction close to or away from the processing turntable 31.

After the rivet 20 is inserted into the inner side of the insertion hole 321, the driving motor 2 drives the processing turntable 31 to rotate so that the supporting seat 32 moves to the loading device 6. At this time, the electromagnetic suction block 62 sucks the steel sheet 10 at the loading bracket 33 and drives the steel sheet 10 to move to the top of the supporting seat 32 and then releases the steel sheet 10. At this time, the steel sheet 10 naturally falls to the top of the supporting seat 32, thereby completing the loading process of the steel sheet 10. The processing turntable 31 continues to rotate and moves the supporting seat 32 to the pressing device 7. At this time, the riveting head 71 at the pressing device 7 slides toward the direction close to the processing turntable 31 and presses down the rivet 20, thereby completing the riveting process of the rivet 20.
