Description

Technical Field

[0001] This utility model relates to the field of hydraulic riveting machine technology, specifically to an automatic feeding mechanism for a hydraulic riveting machine. Background Technology

[0002] A riveting machine, also known as a riveting machine, spin riveting machine, riveting assembly machine, or roll riveting machine, is a mechanical device that uses rivets to rivet items together. It solves the problem that some sheet metal parts cannot be directly placed on ordinary inclined cast steel machines for riveting after bending.

[0003] A search revealed prior art publication number CN211588420U, which discloses an automatic feeding riveting machine, including an upper body, a hydraulic cylinder, a lower body, and a material distribution base. The upper body is positioned above the lower body, and a lower die pressure head is positioned in front of the upper body. The lower die pressure head is fixed to the lower body by bolts. The hydraulic cylinder is positioned on the upper part of the upper body and is connected to the upper body by bolts. An upper die pressure head is positioned below the hydraulic cylinder and is connected to the hydraulic cylinder by threads. The material distribution base and a second support plate are positioned on one side of the upper body. The advantages are: this utility model has a reasonable structure, is simple to operate, and convenient to use. It has automatic material distribution, feeding, and feeding functions, reduces manual labor, improves the practicality of the riveting machine, has a high degree of automation, and allows for faster riveting speed, thereby improving work efficiency.

[0004] However, existing technologies cannot perform real-time mechanical detection of static electricity accumulated by rivets due to friction inside the feeding hopper. This results in static electricity accumulating to a high voltage level before being passively detected, which can easily cause rivets to attract each other, get stuck, or scatter. At the same time, existing solutions cannot immediately and precisely activate ion air to eliminate static electricity after detection. This requires the ion air gun to spray continuously for a long time, which wastes compressed air and high-voltage power. Furthermore, the turbulent airflow causes dust to be stirred up again, ultimately affecting the rivet feeding cycle and the surface quality of the finished product.

[0005] Therefore, based on the above-mentioned search and combined with existing technology, an automatic feeding mechanism for a hydraulic riveting machine is proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In one typical implementation of this application, please refer to Figures 1-5 As shown, an automatic feeding mechanism for a hydraulic riveting machine mainly includes an upper body 1, a lower body 20, a feeding bin 8, and a detection and static elimination mechanism installed in the feeding bin 8.

[0024] A partition 2 is fixedly installed on the inner wall of the upper body 1, and a hydraulic cylinder 3 is fixedly installed on the top surface of the partition 2. The output end of the hydraulic cylinder 3 passes downward through the partition 2 and is connected to an upper die pressure head 5 for performing riveting operations. A guard plate 4 is fixedly installed on the front side wall of the upper body 1. This guard plate 4 provides safety protection for the hydraulic cylinder 3 and its connecting components, preventing interference from external foreign objects or accidental contact by personnel. A feeding hopper 8 is fixedly installed on the top surface of the upper body 1, and a feeding pipe 19 is connected to one side of it for conveying rivets to the processing station. The lower body 20 is located below the upper body 1, and a lower die pressure head 6 is installed on its top surface, which cooperates with the upper die pressure head 5 to complete the riveting. A control button 7 is installed on the front side wall of the lower body 20 for controlling the operation of the entire machine.

[0025] The detection mechanism is installed in the feeding hopper 8. This mechanism mainly includes a sealing plate 9, a connecting column 10, a ball 12, an induction plate 13, an ion gun 15, and a micro switch 18.

[0026] The sealing plate 9 is fixed to the top opening of the feeding hopper 8 by a threaded connection to achieve the sealing of the feeding hopper 8. A downwardly extending connecting post 10 is fixedly installed at the center of the bottom surface of the sealing plate 9. A ball groove 11 is opened on the bottom surface of the connecting post 10, and a ball 12 is rotatably accommodated in the ball groove 11, with part of its spherical surface protruding outside the connecting post 10.

[0027] A sensing plate 13 is fixedly mounted on the bottom surface of the sphere 12. The sensing plate 13 is made of a lightweight conductive material and has sensitive electrostatic induction characteristics. Multiple radially arranged through holes 14 are formed around the sensing plate 13 on the bottom surface of the sphere 12. Multiple mounting slots 17 are formed circumferentially on the inner wall of the ball groove 11, and a microswitch 18 is installed in each mounting slot 17. The contacts of the microswitch 18 face the outer surface of the sphere 12. When the sphere 12 rotates, its surface can press against the contacts of the microswitch 18, changing its state.

[0028] The ion gun 15 is fixedly mounted on the top surface of the sealing plate 9 by a bracket. A through-tube 16 is connected to the air outlet of the ion gun 15. The other end of the through-tube 16 passes downward through the sealing plate 9 and the connecting post 10, and communicates with the internal cavity of the sphere 12. The power circuit of the ion gun 15 is electrically connected to multiple microswitches 18.

[0029] Working principle:

[0030] During automatic feeding, rivets enter the feeding hopper 8 via the feeding pipe 19 and queue up for delivery. Continuous friction between rivets, between rivets and the feeding pipe 19, and the inner wall of the feeding hopper 8 easily generates static electricity. When the static electricity accumulates to a certain level, the charged rivets or the environment inside the hopper will generate an electrostatic attraction force on the induction plate 13 made of conductive material. This attraction force pulls the induction plate 13, causing the entire sphere 12 to deflect slightly within the ball groove 11. The deflection of the sphere 12 causes its spherical surface to press against one or more microswitches 18 arranged on the inner wall of the ball groove 11, causing the microswitches 18 to change from a normally open state to a closed state. The closing of the microswitches 18 connects the power control circuit of the ion gun 15, and the ion gun 15 starts automatically. The generated ion air is transported through the through pipe 16 to the internal cavity of the sphere 12, and finally evenly sprayed out from multiple through holes 14 on the bottom surface of the sphere 12. The ejected positive and negative ion winds act directly on the charged rivets inside the chamber and their surrounding environment, neutralizing the static charge carried on the rivet surfaces. Once the static charge is eliminated, the attraction force on the induction plate 13 disappears. Under the action of gravity and the slight rebound force of the microswitch 18 contacts, the sphere 12 returns to its initial equilibrium position, the microswitch 18 contacts open, the ion gun 15 stops working, and the system waits for the next accumulation of static electricity.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
