Description

Technical Field

[0001] The invention belongs to the technical field of casting devices, and in particular relates to an electrical automation casting device for processing bent metal plates. Background Art

[0002] Metal mold casting is the process of pouring molten metal into a preheated metal mold to obtain a casting. After pouring the molten metal in the mold, it needs to be cooled and then opened to take out the molded metal parts.

[0003] After searching, the application number CN202211314606.3 discloses an automated casting device for processing bent metal plates. The sliding rod slides in the support plate and the support block on the support plate is inserted into and clamps the metal plate, and pushed upward. The metal plate is clamped from above by a manipulator and the material is discharged.

[0004] The above scheme still has some shortcomings in the actual work process: 1. In the above scheme, after the metal plate and the punch are separated, the metal plate is clamped by the support block and pushed upward. However, due to the small thickness and large area of ​​the metal plate, it is difficult to ensure the stability of the metal plate during the upward movement only by clamping it with the support block, and it is easy to slip and shake. In addition, since the gap between the support blocks is fixed, if the gap between the support blocks is too small, it is difficult for the metal plate to enter between the support blocks to complete the clamping work. On the contrary, if it is too large, the side slip and shaking of the metal plate will be more obvious. 2. The metal plate is ejected upward in a vertical state after demoulding. It is difficult for the manipulator of the track plate automatic demoulding machine to accurately grab the metal plate and discharge the material. Moreover, the metal plate discharged in a vertical state needs to be flipped horizontally again before it can be placed stably. 3. This solution has complicated operation steps and low demoulding efficiency, and is not suitable for widespread promotion and use. Summary of the invention

[0005] The purpose of the present invention is to provide an electrical automation casting equipment for processing bent metal sheets in view of the problems raised in the above background technology.

Specific Embodiments

[0020] The following embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0021] As Figure 1-8 shown, an electrical automation casting device for bending metal sheets includes a mounting plate 1, a punch 2, a die 3, a lifting assembly, two side slide plates 12 and a flipping assembly.

[0022] The lifting assembly includes a hydraulic cylinder 4 and a bottom plate 5. The hydraulic cylinder 4 is installed at the bottom of the mounting plate 1, and the bottom plate 5 is fixedly connected to the output end of the hydraulic cylinder 4. A mounting bracket 6 is fixedly connected to the bottom plate 5. A positioning pressure plate 7 and a movable pressure plate 8 are provided on the mounting bracket 6. A C-shaped groove 9 is formed on the mounting bracket 6. The movable pressure plate 8 is rotatably connected to the C-shaped groove 9 through a disc spring 10. A wedge surface is provided at the upper end of the movable pressure plate 8. When the disc spring 10 is in a natural state, the upper end of the movable pressure plate 8 biases towards the punch 2 side to separate the metal plate from the punch 2. A first electric telescopic rod 11 for adjusting the deflection angle of the movable pressure plate 8 is installed on the mounting bracket 6, so that the movable pressure plate 8 deflects to clamp and fix the separated metal plate; After the metal plate is formed, the punch 2 and the die 3 are separated by the hydraulic components on both sides. The hydraulic cylinder 4 drives the bottom plate 5 to move upward. The wedge surface at the upper end of the movable pressure plate 8 is inserted into the gap between the metal plate and the punch 2. As the movable pressure plate 8 moves upward, the metal plate is separated from the punch 2. After the movable pressure plate 8 is separated from the metal plate, the first electric telescopic rod 11 is used to push the movable pressure plate 8 to rotate until the metal plate is clamped and fixed by the movable pressure plate 8 and the positioning pressure plate 7 (the flipping direction of the movable pressure plate 8 is as Figure 4As shown by the arrow, the demolding and fixing of the metal plate are realized. Compared with the prior art, the demolding and clamping of the metal plate can be respectively realized through the flipping state of the movable pressing plate 8, and the efficiency is high and the stability is better.

[0023] A distance adjustment groove 13 is formed on the mounting frame 6. A U-shaped clamping block 14 is slidably connected in the distance adjustment groove 13. A second electric telescopic rod 15 is arranged on the mounting frame 6. The output end of the second electric telescopic rod 15 is connected to the U-shaped clamping block 14. Before the demolding work, first, according to the thickness of the metal plate, by setting the second electric telescopic rod 15 and the U-shaped clamping block 14, the distance between the positioning pressing plate 7 and the movable pressing plate 8 is adjusted, so that the movable pressing plate 8 and the positioning pressing plate 7 can stably press and fix the metal plate to ensure the stability of the metal plate during the discharging process.

[0024] Two side sliding plates 12 are respectively slidably connected to the side walls on both sides of the mounting plate 1. A clamping assembly for fixing the metal plate is arranged on the side sliding plate 12. The input end of the clamping assembly is connected to the bottom plate 5. During the upward movement of the bottom plate 5, the clamping assembly automatically clamps and fixes both sides of the metal plate.

[0025] The clamping assembly includes a slide rail 16 fixed to the side sliding plate 12 and a through hole arranged on the side sliding plate 12. A slider 17 is slidably connected in the slide rail 16. A top rod 18 is fixed to the bottom of the slider 17. The lower end of the top rod 18 is fixedly connected to the surface of the bottom plate 5. A transmission rod 19 is rotatably connected to the side wall of the slider 17. A support rod 20 is fixedly connected to the side sliding plate 12. A pin shaft 21 is fixed on the support rod 20. A chute 22 extending along the length direction of the transmission rod 19 is formed on the transmission rod 19. The pin shaft 21 is inserted into the chute 22 and the pin shaft 21 can slide in the chute 22. A shaft rod 23 is arranged in the through hole. Clamping plates 24 and a fixing plate 25 are respectively connected to both ends of the shaft rod 23. A U-shaped slot for the shaft rod 23 to penetrate through is formed on the mounting plate 1. The U-shaped slot is used for the shaft rod 23 to penetrate through and move up and down in the mounting plate 1. The fixing plate 25 is connected to the mounting plate 1 through a return spring 26. When the return spring 26 is in the natural state, the two clamping plates 24 are away from each other. The setting of the return spring 26 is used to separate and reset the shaft rod 23. A positioning ring is rotatably connected to the shaft rod 23. The upper end of the transmission rod 19 is hinged to the bottom of the positioning ring through a hinge seat; After the metal plate is clamped by the movable pressing plate 8 and the positioning pressing plate 7, the bottom plate 5 continues to move upward. The slider 17 is pushed to move upward along the slide rail 16 by the top rod 18. Due to the design that the pin shaft 21 can only slide in the chute 22, the transmission rod 19 deflects to push the shaft rod 23 to move towards the metal plate. Then the two shaft rods 23 approach the metal plate from both sides, and the metal plate is clamped and positioned by the clamping plates 24 to prevent the metal plate from slipping and deviating to both sides, further ensuring stable discharging.

[0026] The flipping assembly is rotatably connected to the shaft cylinder 28 on the side sliding plate 12. The shaft rod 23 passes through and is slidably connected inside the shaft cylinder 28. A gear 29 is coaxially and fixedly connected to the shaft cylinder 28. A rack 30 matching the gear 29 is fixed on the mounting plate 1. When the gear 29 contacts and meshes with the rack 30, it drives the shaft rod 23 to rotate, causing the metal plate to flip 90°. A flat key 31 parallel to the axis direction is fixedly connected to the side wall of the shaft rod 23. A keyway matching the flat key 31 is provided inside the shaft cylinder 28. The flat key 31 is slidably arranged in the keyway. A base 32 is fixedly connected to the side wall of the mounting plate 1. The upper surface of the base 32 is connected to a bearing plate 27 through a buffer spring 33. The function of the bearing plate 27 is to prevent the side sliding plate 12 from colliding with the base 32 when moving downward, and the buffer spring 33 plays a buffering role; During the upward movement of the metal plate after demoulding, the gear 29 moves to contact the rack 30. Under the meshing action, the gear 29 will drive the shaft rod 23 to rotate 90°. Since the flat key 31 can only slide in the keyway, the gear 29 will drive the shaft rod 23 to rotate synchronously by 90°, automatically flipping the vertically placed metal plate to a horizontal state. On the one hand, it is convenient for the manipulator of the track slab automatic demoulding machine to grab the metal plate. On the other hand, it improves the stability of the metal plate during the discharging and conveying process, eliminating the need for subsequent flipping work and being conducive to improving work efficiency.

[0027] The working principle of the present invention is as follows: Before the demoulding work, first, according to the thickness of the metal plate, by setting the second electric telescopic rod 15 and the U-shaped block 14, the distance between the positioning pressing plate 7 and the movable pressing plate 8 is adjusted, so that the movable pressing plate 8 and the positioning pressing plate 7 can stably clamp and fix the metal plate to ensure the stability of the metal plate during the discharging process; After the metal plate is formed, the punch 2 and the die 3 are separated by the two side hydraulic components. The hydraulic cylinder 4 drives the bottom plate 5 to move upward. The upper wedge surface of the movable pressing plate 8 is inserted into the gap between the metal plate and the punch 2. As the movable pressing plate 8 moves upward, the metal plate is separated from the punch 2. After the movable pressing plate 8 is separated from the metal plate, the first electric telescopic rod 11 is used to push the movable pressing plate 8 to rotate until the metal plate is clamped and fixed by the movable pressing plate 8 and the positioning pressing plate 7, realizing the demoulding and fixing of the metal plate. Compared with the prior art, the demoulding and clamping of the metal plate can be respectively realized through the flipping state of the movable pressing plate 8, and it has high efficiency and better stability; After the metal plate is clamped by the movable pressing plate 8 and the positioning pressing plate 7, the bottom plate 5 continues to move upward. The ejector rod 18 is used to push the slider 17 to move upward along the slide rail 16. Due to the design that the pin shaft 21 can only slide in the chute 22, the transmission rod 19 deflects to push the shaft rod 23 to move towards the metal plate. Then the two shaft rods 23 approach the metal plate from both sides, and the metal plate is clamped and positioned by the clamping plate 24 to prevent the metal plate from slipping and deviating to both sides, further ensuring stable discharging; During the upward movement of the metal plate after demoulding, the gear 29 moves to contact the rack 30. Under the meshing action, the gear 29 will drive the shaft 23 to rotate 90°. Since the flat key 31 can only slide in the keyway, the gear 29 will drive the shaft 23 to rotate synchronously by 90°, automatically flipping the vertically placed metal plate to the horizontal state. On the one hand, it facilitates the grasping of the metal plate by the manipulator of the track slab automatic demoulding machine, and on the other hand, it improves the stability of the metal plate during the discharging and conveying process, eliminating the need for subsequent flipping work and being conducive to the improvement of work efficiency. After the discharging of the metal plate is completed, the hydraulic cylinder 4 drives the bottom plate 5 to move downward and reset. At this time, the side sliding plate 12 moves downward under the action of gravity and stops after contacting the bearing plate 27. The return spring 26 drives the shaft 23 away from the reset position through the fixed plate 25 to facilitate the next casting work.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
