Connecting rods 11 are fixedly connected to the front and rear positions of the bottom of the trigger plate 10. One end of the connecting rod 11 passes through the positioning box 6 and is fixedly connected to the lifting plate 12. The top of the pressure plate 3 is equipped with a PLC controller 13 and a relay 14 from left to right. A limit component 15 is provided on the right side of the top of the pressure plate 3. Slide rails 17 are fixedly connected to the front and rear positions of the right side of the inner cavity of the protective frame 1. The outer surface of the slide rail 17 is slidably connected to the inner surface of the pressure plate 3. Slide tracks 18 are provided on the left and right sides of the inner cavity of the positioning box 6 to cooperate with the trigger plate 10 and the movable plate 7. The inner surface of the slide track 18 is slidably connected to the connection point of the trigger plate 10 and the movable plate 7 respectively. A protective pad is provided at the bottom of the lifting plate 12, and the connection point between the protective pad and the lifting plate 12 is bonded. Support legs 19 are fixedly connected to the four corners of the bottom of the protective frame 1. There are four support legs 19. Anti-slip pads are fixedly connected to the bottom of the support legs 19, and the anti-slip pads are circular.
[0035] In this embodiment: the present invention can stamp and form the spring sheet by setting a protective frame 1, an electric cylinder 2, a pressure plate 3, an upper mold 4, and a lower mold 5. By setting a positioning box 6, a movable plate 7, a pressure sensor 8, a spring 9, a trigger plate 10, a connecting rod 11, a lifting plate 12, a PLC controller 13, and a relay 14, it can stop the object in time when it is detected. By setting the above structure, it has the advantage of foreign object stopping function, thereby meeting the needs of customers and avoiding potential safety hazards.
[0036] Example 2:
[0037] Reference Figure 1 and Figure 2 The limiting component 15 includes a guide rod 151. The bottom of the guide rod 151 is fixedly connected to the connection of the pressure plate 3. The top of the guide rod 151 passes through the protective frame 1 and is fixedly connected to the limiting plate 152. A slide cylinder 16 is embedded in the top of the protective frame 1. The inner surface of the slide cylinder 16 is slidably connected to the outer surface of the guide rod 151.
[0038] In this embodiment: the present invention can guide and limit the pressure plate 3 by setting the guide rod 151 and the limiting plate 152.
[0039] The implementation principle of this utility model is as follows: When in use, the operator connects the device to the mains power. When it is necessary to stamp the spring sheet, the operator places the spring sheet blank in the inner cavity of the lower mold 5. Then, the operator starts the external controller of the electric cylinder 2, so that the extension end of the electric cylinder 2 drives the pressure plate 3 to move downward. The pressure plate 3 drives the upper mold 4 to move downward to stamp the spring sheet blank, so that the upper mold 4 and the lower mold 5 work together to stamp the spring sheet blank. Then, the operator takes out the stamped spring sheet, thus completing the stamping of the spring sheet.
[0040] When the external controller of the electric cylinder 2 is accidentally activated during the loading and unloading process, the telescopic end of the electric cylinder 2 moves the pressure plate 3 downward. Simultaneously, the pressure plate 3 moves the positioning box 6 downward, which in turn moves the trigger plate 10, connecting rod 11, lifting plate 12, and protective pad downward. When the lifting plate 12 and the protective pad come into contact with a foreign object, the object supports it, keeping the lifting plate 12, connecting rod 11, and trigger plate 10 stationary. Meanwhile, the pressure plate 3 continues to move the positioning box 6 downward, causing the positioning box 6 to move the spring 9 and movable plate 7 downward. The moving plate 7 causes the pressure sensor 8 to move downwards continuously and press against the trigger plate 10. At the same time, the pressure sensor 8 transmits data to the PLC controller 13. The PLC controller 13 then processes the data and causes the relay 14 to shut down the electric cylinder 2, thus preventing the electric cylinder 2 from causing the pressure plate 3 to move downwards continuously and squeeze the foreign object. In addition, the spring 9 can buffer the lifting plate 12 when it comes into contact with the foreign object, preventing damage to the foreign object. This device is simple to operate and easy to use to stop foreign objects, thus meeting the needs of customers and avoiding potential safety hazards.
[0041] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is manual control through an external controller. In this application, the electric cylinder 2 can be dually controlled by relay 14 and external control switch. The control circuit of the external controller can be implemented by simple programming by those skilled in the art, which is common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
