Description

Technical Field

[0001] This utility model relates to the field of silicon steel sheet stamping technology, specifically a vacuum adsorption mold for silicon steel sheet stamping. Background Technology

[0002] Silicon steel sheets, also known as silicon steel sheets, are a soft magnetic alloy of silicon and iron with extremely low carbon content. They generally contain 0.5% to 4.5% silicon and are made by hot and cold rolling. The thickness is usually less than 1 mm, hence they are also called thin sheets. The main use of silicon steel sheets is to make the cores of various transformers, motors and generators.

[0003] The production of silicon steel sheets requires the use of stamping machines and stamping dies. Currently available stamping machines and stamping dies can produce silicon steel sheets relatively quickly.

[0004] However, existing stamping presses and stamping dies do not have the function of vacuum adsorption positioning of silicon steel sheets. This leads to the easy occurrence of silicon steel sheet displacement during stamping, which increases the probability of the product becoming defective and scrapping, thus failing to meet production requirements. Therefore, a vacuum adsorption die for stamping silicon steel sheets is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a vacuum adsorption mold for stamping silicon steel sheets. This solves the problem that the lack of a vacuum adsorption positioning function for silicon steel sheets leads to easy displacement of the silicon steel sheets during stamping, thereby increasing the probability of the product becoming a defective product, causing product scrapping, and failing to meet production needs.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a vacuum adsorption mold for stamping silicon steel sheets, comprising a stamping machine body and a stamping mold, wherein an adsorption adjustment component is provided on the inner side of the stamping machine body;

A mounting base is fixedly connected to the top of the moving platform. A vacuum generator is fixedly connected to the top of the mounting base. A vacuum suction cup is fixedly connected to the top of the vacuum generator. Air pipes are fixedly connected to the left and right sides of the vacuum generator. Multiple adsorption heads are fixedly connected to the top of the vacuum suction cup.

[0008] Furthermore, the output shaft of the servo motor is fixedly connected to the end face of the bidirectional lead screw, and there are two mounting bases, which are symmetrically distributed on the inner side of the equipment frame.

[0009] Furthermore, the mobile platform is slidably connected to the movable rod, and the air pipe is connected to the vacuum suction cup.

[0010] Furthermore, a hydraulic cylinder is fixedly connected to the top of the stamping machine body, and a stamping die head is fixedly connected to the output shaft of the hydraulic cylinder. The stamping die is located inside the equipment frame.

[0011] Furthermore, a limiting rod is fixedly connected to the top of the stamping die head, with one end penetrating through the stamping machine body and extending to its top. A limiting block is fixedly connected to the top of the limiting rod.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 A vacuum adsorption mold for stamping silicon steel sheets in this embodiment includes a stamping machine body 1 and a stamping mold 2. An adsorption adjustment component is provided on the inner side of the stamping machine body 1.

[0022] The adsorption adjustment assembly includes a device frame 4 fixedly connected to the bottom wall of the inner wall of the stamping machine body 1. A servo motor 5 is fixedly connected to the outer side of the stamping machine body 1. A bidirectional lead screw 6 is rotatably connected to the inner side of the device frame 4. A moving platform 7 is threadedly connected to the outer surface of the bidirectional lead screw 6. A movable rod 8 is fixedly connected to the inner side of the device frame 4. A mounting base 9 is fixedly connected to the top of the moving platform 7. A vacuum generator 10 is fixedly connected to the top of the mounting base 9. A vacuum suction cup 11 is fixedly connected to the top of the vacuum generator 10. Air pipes 12 are fixedly connected to the left and right sides of the vacuum suction cup 11, and multiple suction heads 13 are fixedly connected to the top of the vacuum suction cup 11. When the silicon steel sheet is being stamped, the vacuum suction cup 11 is connected to the vacuum generator 10 through the air pipes 12. When the vacuum equipment is started, it begins to extract the air inside the vacuum suction cup 11 and the air in the sealed space formed by the contact between the suction cup and the silicon steel sheet, so that the air pressure in the space drops rapidly and forms a negative air pressure state, that is, lower than the external atmospheric pressure. Because the air pressure inside the vacuum suction cup 11 is lower than the external atmospheric pressure.

[0023] Under atmospheric pressure, the outside air exerts an inward pressure on the vacuum suction cup 11, causing the silicon steel sheet to adhere tightly to the top of the suction head 13 of the vacuum suction cup 11. At the same time, this pressure difference generates a strong adsorption force between the suction head 13 and the silicon steel sheet, thus firmly holding the silicon steel sheet in place. This reduces the probability of the silicon steel sheet shifting during stamping and also reduces the probability of the product becoming defective, better meeting production needs.

[0024] Before the vacuum suction cup 11 adsorbs and positions the silicon steel sheet, the operator can start the servo motor 5 to control the forward and reverse rotation frequency of the output shaft of the servo motor 5, so that the bidirectional lead screw 6 rotates clockwise or counterclockwise inside the equipment frame 4. Then, under the sliding limit action of the movable rod 8, the two moving platforms 7 drive the two vacuum suction cups 11 to move closer to or further away from each other. Finally, the relative distance between the two vacuum suction cups 11 is adjusted to suit silicon steel sheets of different lengths and sizes.

[0025] It should be noted that the output shaft of the servo motor 5 is fixedly connected to the end face of the bidirectional lead screw 6, there are two mounting bases 9, which are symmetrically distributed on the inner side of the equipment frame 4, the moving platform 7 is slidably connected to the movable rod 8, and the air pipe 12 is connected to the vacuum suction cup 11.

[0026] It should be understood that a hydraulic cylinder 14 is fixedly connected to the top of the stamping machine body 1, and a stamping die head 3 is fixedly connected to the output shaft of the hydraulic cylinder 14. The stamping die 2 is set inside the equipment frame 4. A limiting rod 15 is fixedly connected to the top of the stamping die head 3, with one end penetrating through the stamping machine body 1 and extending to its top. A limiting block is fixedly connected to the top of the limiting rod 15. A cylinder 16 is fixedly connected to the back of the stamping machine body 1, and a push plate for ejecting silicon steel sheets is fixedly connected to the output shaft of the cylinder 16. By setting the cylinder 16, after the silicon steel sheet is stamped, the cylinder 16 can drive the push plate to move forward continuously to eject the silicon steel sheet to the outside of the stamping machine body 1, thereby facilitating the unloading of materials by the operator.

[0027] In addition, a support frame 17 is fixedly connected to the bottom of the stamping machine body 1, and an auxiliary frame 18 is fixedly connected to the inner side of the support frame 17. Multiple first rotating rollers 19 and second rotating rollers 20 for rolling silicon steel sheets are rotatably connected to the inner side of the auxiliary frame 18. Before stamping the silicon steel sheet, the operator can insert the silicon steel sheet between the first rotating roller 19 and the second rotating roller 20 and push and pull it back and forth, so as to roll the protrusions that may exist on the silicon steel sheet through the first rotating roller 19 and the second rotating roller 20 to ensure the stamping quality.

[0028] The working principle of the above embodiments is as follows:

[0029] During the stamping of the silicon steel sheet, since the vacuum suction cup 11 is connected to the vacuum generator 10 via the air pipe 12, when the vacuum equipment is started, it begins to extract the air from inside the vacuum suction cup 11 and the sealed space formed by the contact between the suction cup and the silicon steel sheet. This causes the air pressure in the space to drop rapidly, forming a negative pressure state, that is, lower than the external atmospheric pressure. Because the air pressure inside the vacuum suction cup 11 is lower than the external atmospheric pressure, under the action of atmospheric pressure, the external air will exert an inward pressure on the vacuum suction cup 11, causing the silicon steel sheet to adhere tightly to the top of the suction head 13 of the vacuum suction cup 11. At the same time, this pressure difference... A strong adsorption force is generated between the adsorption head 13 and the silicon steel sheet, thus firmly holding the silicon steel sheet for stamping processing. Before the vacuum suction cup 11 adsorbs and positions the silicon steel sheet, the operator can start the servo motor 5 to control the forward and reverse rotation frequency of the output shaft of the servo motor 5, so that the bidirectional lead screw 6 rotates clockwise or counterclockwise inside the equipment frame 4. Then, under the sliding limit action of the movable rod 8, the two moving platforms 7 drive the two vacuum suction cups 11 to move closer or further away from each other. Finally, the relative distance between the two vacuum suction cups 11 is adjusted to suit silicon steel sheets of different lengths.

Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
