From 10kV and below low-voltage distribution lines, to 220kV high-voltage transmission lines, and even to substations, various iron accessories such as cross arms, hoops, and hangers are indispensable. With the continuous advancement of China's power infrastructure construction, and the vigorous development of new energy industries such as wind power and photovoltaic power generation, the demand for power iron accessories is growing, not only in quantity, but also in quality and performance.

[0003] Angle steel, due to its unique angular structure, is widely used in the manufacture of power iron accessories. Angle steel stamping, as a key process for processing angle steel, causes plastic deformation of angle steel in the die through pressure, thereby obtaining the required shape and size of the parts. However, traditional angle steel stamping technology has many problems. For example, during the punching process, due to the gap between the die and the angle steel, the angle steel cutout is prone to deflection, affecting product accuracy; for complex-shaped iron accessories, traditional stamping processes often require multiple sets of dies, which is costly and inefficient.

[0046] When bending, the matching plate 103 will produce displacement deviation when rotating with the power accessory. By setting the first pressing plate 101 and the matching plate 103 in a sliding connection to produce relative displacement, friction between the first pressing plate 101 and the power accessory when bending can be avoided.

The mounting frame 409 is fixedly installed on the support frame 308, and one side of the mounting frame 409 is fixedly installed on a positioning plate 408. The top of the conveying device 410 is higher than the top of the support plate 100. In this arrangement, the conveying device 410 is used to place the un-stamped power iron accessories and convey them to the support plate 100.

[0056] As shown in Figure 7As shown, further, the pushing mechanism further comprises a sliding seat 401 fixedly installed on one side of the support frame 308, a sliding rod 402 slidingly connected to the sliding seat 401, a tooth groove 403 formed in the sliding seat 401, a second fixing seat 407 fixedly installed on one side of the positioning plate 408, a second rotating shaft 406 rotatably installed on the second fixing seat 407, a gear 405 fixedly installed on the second rotating shaft 406, and the gear 405 and the tooth groove 403 are in meshing connection. In the present arrangement, the second rotating shaft 406 and the first rotating shaft 302 are connected through a sprocket and a chain. When the second curved surface 3032 of the cam 303 is located at the bottom, the top position of the guide block 404 is lower than the top position of the support plate 100. When the first curved surface 3031 of the cam 303 is located at the bottom, the top position of the guide block 404 is higher than the top position of the support plate 100, so that the second pressing plate 102 is in the state of rising when the guide block 404 sends the iron accessory into the support plate 100.

[0057] As shown in Figure 2 , Figure 3 As shown, further, the bottom of one of the limiting sleeves 307 is fixedly installed with a connecting piece 500, and a power mechanism is arranged on the connecting piece 500.

In the present arrangement, the power device 501 is driven by an electric motor, and the transmission module 502 adopts a set of intermeshing bevel gears.

[0058] The implementation principle of the stamping forming device and the stamping die for the electric iron accessory in the present embodiment is as follows. When stamping, the power device 501 works and drives the first rotating shaft 302 to rotate through the transmission module 502, the first rotating shaft 302 drives the cam 303 to rotate, so that the second curved surface 3032 of the cam 303 rotates to the bottommost position. At this time, the cam 303 pushes the lower pressing plate 304 downward, and in the process, the mounting plate 306 is lowered through the lifting plate 305, the mounting plate 306 drives the second pressing plate 102 to descend, so as to press the electric iron accessory placed on the support plate 100.

[0059] At this time, the oil cylinder 204 is started, the pushing force of the oil cylinder 204 is transmitted to the stop rod 207 through the connecting rod 205 and the connecting plate 206, the pushing force of the stop rod 207 is applied to the guide plate 203, and the upward movement of the stop rod 207 is realized under the reverse action of the guide plate 203. At the same time, since the pushing force direction of the stop rod 207 acts on the guide plate 203, the stop rod 207 will be subjected to a reverse pushing force deviating to one side, thereby driving the oil cylinder 204 and the cooperating plate 103 to reverse, and bending the electric iron accessory.

[0060] When the iron accessories are fed, the conveying device 410 sends the iron accessories between the support plate 100 and the second pressing plate 102 through the transmission belt of the conveying device 410. When the iron accessories are separated from the conveying device 410, the first rotating shaft 302 drives the second rotating shaft 406 to rotate through the chain wheel and the chain. The second rotating shaft 406 drives the gear 405 to rotate in the process of rotating. The gear 405 drives the sliding rod 402 to move through the meshing with the gear slot 403, so as to drive the guide block 404 to move. The guide block 404 abuts against the edge position of the iron accessories in the process of moving, so as to completely send the iron accessories between the support plate 100 and the second pressing plate 102.

[0061] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present application but not limit the present application. Although the present application is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced equivalently without departing from the spirit and scope of the technical solutions of the present application, which should be covered in the scope of the claims of the present application.
