[0022] Preferably, a stamping cylinder 3 is fixedly inserted through the first end of the top side plate of the U-shaped support frame 2, and a stamping column 4 is fixedly inserted into the bottom end of the telescopic rod of the stamping cylinder 3; the stamping cylinder 3 is connected to an external hydraulic power unit through a high-pressure oil pipe to transmit and deliver hydraulic driving force, and a reversing solenoid valve is configured on the high-pressure oil pipe.

[0024] Preferably, an electrical control box 8 is fixedly suspended at the bottom of the front side of the processing table 1. The electrical control box 8 is equipped with a control unit for controlling the extension and retraction of the stamping cylinder 3. The solenoid valve is electrically connected to the control unit. The control unit adjusts and changes the valve core position of the solenoid valve by controlling the energization or de-energization of the solenoid valve coil, thereby switching the oil circuit and controlling the extension and retraction of the stamping cylinder 3.

[0025] The working principle, specific details, implementation steps, functions and interrelationships of the features in the above embodiments, and the roles these features play in realizing this technical solution will be described and explained in detail below: The through-hole on the sheet metal part 5 to be processed is fitted with the positioning shaft 601 to efficiently align the positioning shaft 601 through the through-hole and the rivet stud 7 in one go. Thus, the positioning shaft 601 is the positioning and calibration mechanism for both the through-hole and the rivet stud 7. Compared with the prior art which lacks a positioning and calibration mechanism, this utility model can save the trouble of frequently and repeatedly adjusting the sheet metal part 5 by hand to calibrate and align the through-hole and the rivet stud 7 during the riveting process. The operation is convenient and time-saving, which helps to indirectly improve the processing and production efficiency of the riveting device.

[0026] During the riveting process, firstly, the through-hole on the sheet metal part 5 is fitted with the positioning shaft 601 (e.g., Figure 1 (As shown), then the stud cap 701 is inserted into the limiting ring 9 and magnetically fixed to the bottom end of the stamping column 4, so that the rivet stud 7 is magnetically suspended at the bottom end of the stamping column 4. Then, the stamping cylinder 3 is started. After the stamping cylinder 3 is started, its telescopic rod automatically extends and retracts one stroke. When the telescopic rod extends downward, it drives the rivet stud 7 to move together and controls the rivet stud 7 to abut against the positioning shaft 601, pushing the positioning shaft 601 downward and retracting it into the sliding hole 602. At the same time, the rivet stud 7 is driven to slide down through the through riveting hole and inserted into the sliding hole 602. After the rivet stud 7 is inserted into the sliding hole 602, the stud cap 701 and the ring of serrations 702 on its bottom side are pressed and embedded in the through riveting hole under the continuous downward drive of the stamping cylinder 3, realizing the riveting connection between the rivet stud 7 and the sheet metal part 5. When the riveting process is completed, the telescopic rod extends upward and retracts to reset, thus completing one riveting operation.

[0027] In the above process, when the positioning shaft 601 is pressed down and retracted by the rivet stud 7, the spring in the sliding hole 602 is compressed. When the positioning shaft 601 is pressed down and retracted, it can prevent the rivet stud 7 from protruding and supporting the top of the bearing column 6 for a long time during the riveting process, thus avoiding obstruction and hindering the riveting fit between the rivet stud 7 and the through riveting hole, and affecting the normal and effective execution of the riveting process. The limiting ring 9 is used to confine the stud cap 701 and the rivet stud 7 to the center position of the bottom end of the stamping column 4, so as to ensure that the rivet stud 7 is concentrically aligned with the positioning shaft 601 and the through riveting hole, and to prevent the rivet stud 7 from not being centered at the center position of the bottom end of the stamping column 4 during magnetic installation. Because the rivet hole is misaligned and cannot be properly riveted, when the bottom end of the stamping column 4 presses against the top end of the bearing column 6 to rivet the stud 7, the limiting ring 9 protrudes from the bottom end of the stamping column 4, and thus first comes into contact with the top end of the bearing column 6. It is then pushed inward and hidden in the annular groove 401, keeping the bottom riveting surface of the bearing column 6 flat. This prevents the bottom riveting surface of the bearing column 6 from protruding for a long time, affecting the flatness of the bottom riveting surface of the bearing column 6, and preventing the bottom riveting surface from contacting the top end of the bearing column 6 to perform the riveting operation. This helps to ensure the normal and effective implementation of the riveting operation.

[0028] It is worth noting that the composition of the control unit, the selection of the model of the reversing solenoid valve, and the connection and wiring relationship between the two are existing technologies for technicians engaged in equipment electrification modification, design, and testing in this field, and therefore will not be elaborated here.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
