Support components 12 are provided at the four corners of the bottom of the protective frame 1. The front and rear positions of the top right side of the inner cavity of the protective frame 1 are fixedly connected to the slide rail 14. The outer surface of the slide rail 14 is slidably connected to the inner surface of the pressure plate 7. The left side of the top of the inner cavity of the protective frame 1 is provided with a lighting lamp 15. The lighting lamp 15 is fixedly connected to the connection of the protective frame 1 by screws. The left side of the rotating plate 4 extends to the outside of the protective frame 1. There are two lower molds 5. An observation window 16 is embedded in the front of the protective frame 1. The observation window 16 is rectangular.

[0034] In this embodiment: the present invention, by setting a rotating shaft 2, a reinforcing plate 3, a rotating plate 4, a lower mold 5, a servo motor 9, a driving gear 10, and a driven gear 11, can rotate and load / unload the spring sheet. By setting an electric cylinder 6, a pressure plate 7, and an upper mold 8, the spring sheet can be pressed and bent. By setting the above structure, the spring sheet can be safely loaded and unloaded, thereby meeting the customer's usage needs and avoiding potential safety hazards.

[0035] Example 2:

[0036] Reference Figure 1 , Figure 2 and Figure 3 The support assembly 12 includes a stud 121, a support cylinder 122 is threadedly connected to the outer surface of the stud 121, a caster wheel 123 is movably connected to the bottom of the stud 121, a reinforcing plate 13 is fixedly connected to the bottom of the support cylinder 122, a rubber pad is fixedly connected to the bottom of the reinforcing plate 13, the top of the stud 121 is fixedly connected to the connection of the protective frame 1, and a locking plate is provided on one side of the caster wheel 123.

[0037] In this embodiment: By setting studs 121, support cylinders 122 and casters 123, the present invention can easily move and support the device, and at the same time, adjust its horizontal state.

[0038] The implementation principle of this utility model is as follows: When in use, the operator moves the device to the designated position using the casters 123. Then, the operator rotates the support cylinder 122 in sequence, causing the support cylinder 122 to drive the reinforcing disc 13 to rotate and move downward on the outer surface of the stud 121. At the same time, the reinforcing disc 13 drives the rubber pad to move downward and contact the ground. Thus, the four reinforcing discs 13, the rubber pad and the support cylinder 122 work together to support the device and adjust its horizontal state.

[0039] When it is necessary to press and bend the spring sheet, the operator connects the device to the mains power. Then, the operator places the spring sheet blank in the lower mold 5 on the left. Next, the operator starts the external controller of the servo motor 9, so that the output end of the servo motor 9 drives the drive gear 10 to rotate. The drive gear 10 drives the driven gear 11 to rotate. The driven gear 11 drives the rotating shaft 2 to rotate, so that the rotating shaft 2 drives the rotating plate 4 to rotate. The rotating plate 4 drives the lower mold 5 on the left, which contains the spring sheet blank, to rotate and move to the bottom of the upper mold 8. At the same time, the rotating plate 4 drives the lower mold 5 on the right to rotate and move out of the inner cavity of the protective frame 1. Then, the operator places the spring sheet blank in the lower mold 5 on the right, thus achieving safe feeding of the spring sheet blank. At the same time, the operator starts the external controller of the electric cylinder 6, so that the extension end of the electric cylinder 6 drives the pressure plate 7 to slide downward on the outer surface of the slide rail 14. At the same time, the pressure plate 7 drives the upper mold 8 to move downward and press and contact the spring sheet blank. Thus, the upper mold 8 and the lower mold 5 work together to press and bend the spring sheet blank.

[0040] After the spring blank is pressed and bent into shape, the operator restarts the external controller of the servo motor 9, causing the output end of the servo motor 9 to drive the drive gear 10 to rotate in the opposite direction. The drive gear 10 drives the driven gear 11 to rotate in the opposite direction, and the driven gear 11 drives the rotating shaft 2 to rotate in the opposite direction. This causes the rotating shaft 2 to drive the rotating plate 4 to rotate in the opposite direction, which in turn causes the left lower mold 5 and the bent spring blank to rotate in the opposite direction and return to their initial positions. At the same time, the right lower mold 5, which holds the spring blank, rotates and moves to the bottom of the upper mold 8. Then, the operator starts the external controller of the electric cylinder 6, causing the extension end of the electric cylinder 6 to drive the pressure plate 7 and the lower mold 5 to move downward to press and bend the spring blank. Meanwhile, the operator removes the bent spring blank and places it back into the lower mold 5, thus achieving safe feeding of the device. This process is repeated to achieve the pressing and bending of the spring blank. The device is simple to operate and easy to use for safe feeding and unloading, thus meeting the needs of customers and avoiding potential safety hazards.

[0041] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
