[0038] In this embodiment, the reset rope 112 has elasticity.

[0039] In this embodiment, a rubber block 115 is provided on the bottom surface of the end of the pressure rod away from the center of the upper cover 5, which improves the applicable range of the pressure rod when clamping parts and avoids rigid connection, causing damage to the pressure rod and the electric push rod 114.

[0040] More specifically, the stamping device 12 includes: a base 121, a hydraulic push rod 122, a punch 123, and a die 124. The bottom of the base 121 is installed on one side of the upper wall surface of the upper cover 5. The base 121 is a Z-shaped structure. The hydraulic push rod 122 is installed on the top of the base 121. The output end of the hydraulic push rod 122 is vertically downward. The punch 123 is installed at the output end of the hydraulic push rod 122. The die 124 is clamped in the annular groove 7 and corresponds to the position of the slot 6. The die 124 and the punch 123 are located on the same vertical axis.

[0041] A forming method of a stamping and forming device with multiple riveting operations includes the following steps:

[0042] S1. When it is necessary to perform stamping and riveting on the sheet metal, the die 124 is clamped in the annular groove 7. The sheet metal with a longer length is moved along the tangential direction of the housing 4 where the stamping device 12 is located. The auxiliary device 11 fixes the sheet metal at the stamping working position, and then controlling the stamping device 12 can perform riveting on the sheet metal.

[0043] S2. When it is necessary to use rivets to rivet the sheet metal, the die 124 is removed. The first motor 3 and the second motor 9 drive the housing 4 and the transmission plate 102 to rotate. The rivet is inserted into the hole position of the sheet metal and inserted through the slot 6. The lower part of the stamping device 12 is the riveting working area. When the sheet metal with the rivet moves to the working area, the bottom end of the rivet is clamped by the fixing device 10. When the housing 4 continues to rotate and the sheet metal moves to the plug board 13, the rivet is pulled to complete the riveting.

[0044] S3. When continuously riveting a small-sized single part, the operator can be in the alignment position of the stamping device 12, place the part on the upper cover 5, place the rivet at the hole position, and fix it through the auxiliary device 11. When moving to the working area, the fixing device 10 fixes the bottom of the rivet, increases the distance between the part and the housing 4 through the inserting plate 13, pulls the rivet, and completes the riveting.

[0045] Embodiment: When stamping and riveting a plate of an elongated structure, pass the plate under the stamping device 12 and insert it along the tangential direction of the housing 4. When the plate is located between the punch 123 and the groove, the electric push rod 114 pushes the support block 113 radially, and one end of the pressure rod close to the center of the upper cover 5 will tilt up, and the other end will squeeze and fix the plate. At this time, the hydraulic push rod 122 works, and the two plates are riveted by using the punch 123 and the die 124. After the riveting is completed, the output end of the electric push rod 114 moves in the reverse direction. Under the action of the reset rope 112, one end of the pressure rod close to the center of the upper cover 5 will move downward, and the other end of the pressure rod will tilt up. At this time, moving the plate can connect and rivet;

[0046] When riveting a plate with a rivet, place the rivet at the hole position of the plate, place the plate at the slot 6 under the stamping device 12, and the bottom end of the rivet is inserted into the slot 6. At this time, control the motor to rotate in a reciprocating small angle, and this angle satisfies that the fixing device 10 fixes the rivet and rotates with the housing 4 through the inserting plate 13 to complete the riveting operation, and complete the riveting operation of using the rivet on the plate;

[0047] When it is necessary to use a rivet to rivet a small part, remove the die 124 from the upper cover 5, stand at the alignment position of the stamping device 12, place the rivet on the hole positions of the two parts, and insert it into the slot 6. The auxiliary device 11 fixes it. When the housing 4 is driven by the first motor 3 to rotate, when the part rotates with the housing 4 to the lower part of the stamping device 12, the second motor 9 drives the transmission plate 102 through the eccentric shaft 101, and drives the push block 104 to move radially along the upper cover 5 in the frame 105 by using the connecting rod 103. With the cooperation of the first motor 3 and the second motor 9, when the housing 4 rotates, ensure that the push block 104 and the top block 106 located under the stamping device 12 can fix the bottom end of the rivet. At the same time, the top block 106 is fixed in the sliding groove 8 through the top screw 107, and the position of the top block 106 can be adjusted according to different sizes of rivets. The shape of the slot 6 can also meet different sizes of rivets. When the bottom end of the rivet is fixed, the housing 4 continues to rotate. When the part contacts the inserting plate 13, the part will be lifted by the arc-shaped inserting plate 13. At the same time, the electric push rod 114 synchronously retracts the output end, so that the pressure of the pressure rod on the part slowly decreases. When the part is lifted, the rivet will be fixed and the bottom end will be broken, and the two parts complete the riveting operation;

[0048] When stamping and riveting small parts, place the parts on the upper cover 5 at the alignment position of the stamping device 12 and fix them through the corresponding auxiliary device 11. The first motor 3 drives the housing 4 to rotate, and the parts rotate accordingly. The female dies 124 are respectively installed in the corresponding annular grooves 7. When the parts move below the male die 123, the hydraulic device works to complete the stamping and riveting. The housing 4 continues to rotate. At this time, the auxiliary device 11 releases, and the parts can be removed to complete the riveting.

[0049] The control methods and programs of the first motor, the second motor, the electric push rod and the hydraulic push rod, as well as the electrical connection methods, are not described in the present invention and all belong to the technologies well known to those skilled in the art.

[0050] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
