Specific implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0025] Refer to Figure 1 - Figure 2 As shown, it includes a base plate 2, a lower die 5 is provided above the base plate 2, an upper die 4 is provided directly above the lower die 5, and the upper die 4 is connected to a hydraulic device through a hydraulic plate; a back plate 1 is provided at the rear side of the base plate 2, and an automatic pushing structure is provided on one side of the upper die 4 and the lower die 5, and an automatic lifting structure is provided on one side of the upper die 4 and the lower die 5.

[0026] Refer to Figure 1 - Figure 4 As shown, the automatic pushing structure includes two sets of automatically driving components with the same symmetrical structure. Side mounting plates 6 are provided at the front side edges of the base plate 2. The two sets of automatically driving components are respectively provided on the back plate 1 and the side mounting plates 6, and a flexible pushing shaft 27 is connected in front of the two sets of automatically driving components;

[0027] One of the automatic driving components includes a movable plate 7 installed on the back plate 1 through a rotating shaft 8. The movable plate 7 is an "L"-shaped plate arranged downward. The installation part of the rotating shaft 8 is located at the right angle of the movable plate 7. Limiting blocks 9 are respectively arranged on both sides of the movable plate 7 on the rotating shaft 8. And the height of the rotating shaft 8 is the same as the highest moving height of the hydraulic driving plate 3. A first movable slot 10 and a second movable slot 12 are respectively opened on the movable plate 7. On one side of the hydraulic driving plate 3, several driving connecting rods 11 are provided. One end of the driving connecting rod 11 is provided with a pin shaft, and the pin shaft of the driving connecting rod 11 is slidably installed in the first movable slot 10. A slide rail 14 is arranged on the back plate 1. The height of the slide rail 14 is slightly higher than that of the lower die 5. A slider 15 is slidably installed on the slide rail 14. Several passive connecting rods 13 are connected to the slider 15 through a connecting block. One end of each of the several passive connecting rods 13 is provided with a pin shaft, and the pin shaft of the passive connecting rod 13 is slidably installed in the second movable slot 12. The right end of the inner passive connecting rod 13 is connected to a driving arm 17. The right end of the driving arm 17 is connected to one end of a flexible push shaft 27.

[0028] Rotating slots 16 for the movement of the movable plate 7 are respectively opened on the base plate 2 at positions directly below the two movable plates 7.

[0029] As an optimized solution of the utility model, when the hydraulic driving plate 3 is performing stamping, it can drive the driving connecting rod 11 to move downward, thereby driving the right side of the movable plate 7 to rotate downward along the rotating shaft 8, and making the pin shaft at one end of the driving connecting rod 11 slide in the first movable slot 10. At the same time, the rotation of the movable plate 7 will drive the passive connecting rod 13 and the slider 15 to move to the left, and drive the driving arm 17 and the flexible push shaft 27 to move to the left, exiting the stamping range. At the same time, the pin shaft on the passive connecting rod 13 slides in the second movable slot 12. When the stamping is completed and the hydraulic driving plate 3 moves upward, it will drive the driving arm 17 and the flexible push shaft 27 to push parallel to the right through the movable plate 7.

[0030] See Figure 1 - Figure 4 As shown, the automatic lifting structure includes several telescopic rods 18 arranged on the lower side of the hydraulic driving plate 3. And the several telescopic rods 18 are all located on the side of the upper die 4. A lifting slot 20 is opened in the lower die 5 at the corresponding position below each telescopic rod 18. Several lifting sliding slots 22 are opened upward in the lifting slot 20. A lifting shaft 19 is arranged in the lifting slot 20. One end of the lifting shaft 19 is connected to the lower end of the corresponding telescopic rod 18. Several lifting columns 21 are connected to the lifting shaft 19. And each lifting column 21 is correspondingly arranged in the lifting sliding slot 22.

[0031] The telescopic rod 18 is composed of multiple nested unit tubes. An inner flange 24 is provided at the lower end of each unit tube. An outer flange 25 matching the inner flange 24 of the upper unit tube is provided at the top of the lower unit tube. And a movable magnetic ring 26 matching the shape of the outer flange 25 thereon is provided at the top of each unit tube. A fixed magnetic block 23 is provided at the inner top of the unit tube at the top of the telescopic tube.

[0032] As an optimized solution of the present utility model, by utilizing the movement of the hydraulic driving plate 3 itself, when it moves downward, the telescopic rod 18 automatically shortens. At the same time, the tops of the nested unit tubes gradually approach the fixed magnetic block 23 at the top. Then several movable magnetic rings 26 will automatically adsorb to the fixed magnetic block 23. At the same time, the lifting shaft 19 connected to the lower part of the telescopic rod 18 will move down to the bottom of the lifting groove 20, so that the lifting column 21 retracts into the lifting sliding groove 22 to perform the stamping process. After the stamping is completed, the hydraulic driving plate 3 moves upward. First, due to the magnetic adsorption effect in the telescopic rod 18, the telescopic rod 18 will not immediately elongate, but gradually apply an upward pulling force to the lifting shaft 19, and push out the stamped part by sliding upward through the lifting column 21. Then, as the upward movement distance and force of the hydraulic driving plate 3 increase, the movable magnetic ring 26 gradually separates from the fixed magnetic block 23, and the telescopic rod 18 begins to gradually elongate.

[0033] The usage process of the present utility model:

[0034] First, install the equipment. Then, put the raw material to be stamped on the lower die 5 and start the hydraulic device. As the hydraulic driving plate 3 descends, the hydraulic driving plate 3 gradually drives the automatic pushing structure to retract the flexible pushing shaft 27, and at the same time, the automatic lifting structure retracts the lifting column 21, and then starts stamping;

[0035] After the stamping is completed, the hydraulic device starts to retract, driving the hydraulic driving plate 3 to move upward. The flexible pushing shaft 27 is pushed parallel to the right through the automatic pushing structure. At the same time, the automatic lifting structure pushes the lifting column 21 upward from the lifting sliding groove 22 to push out the stamped part from the lower die 5, and the flexible pushing shaft 27 pushes the pushed-out part to the right. Then, new stamping raw materials can be put in and stamping can be performed again.

[0036] It should be understood that the above specific embodiments of the present utility model are only used for exemplary illustration or explanation of the principle of the present utility model, and do not constitute a limitation to the present utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the present utility model shall be included within the protection scope of the present utility model.
