When the riveting is completed, the rivet gun 67 returns to the initial position under the action of the sixth telescopic cylinder 65. At the same time, the spring 607 contracts to drive the rivet receiving rack 68 back to the initial position.

[0032] The automatic rivet feeding mechanism 7 includes a rivet feeding rack 71. At the top of the rivet feeding rack 71, there is a feeding port 72. Inside the rivet feeding rack 71, there is a rivet chuck 73. At the central axis of the rivet chuck 73, there is a rotating shaft 74. At one end of the rotating shaft 74, there is a crank 75. At the other end of the rotating shaft 74, there is a gear 76. Engaged with the gear 76 is a chain 77. One end of the chain 77 is connected to a sixth telescopic cylinder 78, and the sixth telescopic cylinder 78 is fixed on a ninth mounting plate 79. The other end of the chain 77 is connected to the ninth mounting plate 79 through a connecting rope. At the bottom end of the rivet feeding rack 71, there is a rivet feeding pipe 711, and the bottom opening of the rivet feeding pipe 711 faces the rivet receiving port 69 exactly. Rivets are put in from the feeding port 72. The sixth telescopic cylinder 78 pulls the rotating shaft 74 through the chain 77. At the same time, under the action of the rivet chuck 73, the rivets flow down one by one from the rivet feeding pipe 711 and fall into the rivet receiving port 69, realizing the automatic feeding of rivets.

[0033] On the front side of the fourth mounting plate 36, there is a discharging rack 8. After riveting, the hanger is ejected under the combined action of the pushing cylinder 295 and the springing cylinder 391, and then the formed hanger falls on the discharging rack 8 to realize automatic discharging.

[0034] On the frame 1, there are a controller and a switch button. The operation of all cylinders is controlled by the controller, and then the automation mode of the hanger production equipment is realized by programming the controller. The operation and stop of the equipment are realized by pressing the switch button.

[0035] In use: The operation of all cylinders is controlled by a controller, and the automation mode of the hanger production equipment is realized by editing a program for the controller. The operation and stop of the equipment are achieved by pressing the switch button. First, the metal strip for making hangers can be inserted through the workpiece slot 594 of the mold 593 either by machine feeding or manual feeding, passing through between the second top wheel 48 and the second forming template 49, then through between the two central columns 384 and the side columns 385, then through between the arc-shaped lifting plate 387 and the arc-shaped template 388, then through between the first top wheel 28 and the first forming template 29, and the metal strip is resisted and limited by the U-shaped baffle 294. Then, the first cylinder 54 and the second cylinder 58 operate, and the first punching head 56 and the second punching head 591 simultaneously punch the metal strip in the workpiece slot 594, and the metal strip between the two punches is cut off by the cutting blade 57. Then, the lifting cylinder 386 drives the arc-shaped lifting plate 387 to rise and pushes the metal strip on it into the arc-shaped template 388, forming the bottom end of the hanger while fixing the metal strip. Then, the first telescopic cylinder 23 drives the first slider 24 to move on the first slide rail 25, and at the same time, the first top wheel 28 also moves with it and pushes the metal strip into the first forming template 29 to complete the forming of the left end of the hanger. At the same time, the third telescopic cylinder 43 drives the fifth mounting plate 46 to move on the fourth slide rail 45, and the metal strip on it is pushed into the second forming template 49 to complete the forming of the right end of the hanger. Then, the second telescopic cylinder 390 drives the auxiliary mechanism 3 as a whole to move backward and sideways on the second slide rail 33, and then the rotary cylinder 382 rotates to drive the rotary plate 383 to rotate, and the metal strip between the central column 384 and the side column 385 is rotationally bent, and the left and right ends of the metal strip move closer to the middle at the same time. Then, the fifth telescopic cylinder 64 drives the eighth mounting plate 63 to move to the left, and the sixth telescopic cylinder 65 drives the rivet gun 67 to move to the right and rivet the left and right ends of the hanger. The rivet receiving rack 68 plays a role in limiting the rivets in the rivet receiving port 69. At the same time, under the action of the elastic telescopic mechanism 60, the rivet receiving rack 68 automatically contracts and rebounds to the initial position after riveting. At the same time, the fifth telescopic cylinder 64 drives the eighth mounting plate 63 to move to the right and return to the initial position. When the rivets in the rivet receiving port 69 are used up, the rivet automatic feeding mechanism 7 makes the rivets flow down from the rivet feeding pipe 711 and fall into the rivet receiving port 69 to realize the automatic feeding of rivets. This equipment belongs to an integrated hanger production machine. Compared with the existing pipeline-type hanger production equipment, this equipment has a simpler structure, is more convenient to assemble, is also easy to move as a whole, occupies less space, and greatly reduces the production cost.In actual production, this equipment can flexibly change the number of the first top wheels 28, the template shape of the corresponding first forming template 29, the number of the second top wheels 48, and the template shape of the corresponding second forming template 49 according to hangers with different shapes and appearances. Therefore, this equipment only needs to be slightly adjusted to produce hangers with different appearances. Moreover, this equipment connects the two ends of the hanger by riveting, replacing the way of connecting the two ends of the hanger by entanglement in the prior art, improving the connection efficiency and also the production efficiency of the hanger.
