Description

Technical Field

[0001] This utility model relates to the field of industrial manufacturing technology, specifically to a steel core pressing device. Background Technology

[0002] Silicon steel core pressing equipment is a specialized device used to manufacture silicon steel cores for electrical equipment such as motors and transformers. Silicon steel cores are usually made by stacking silicon steel sheets. The silicon steel sheets need to be insulated to reduce eddy current losses. The outer circle of the silicon steel sheet is usually fitted onto a mold called the pressing core. The pressing core is the core part of the pressing equipment. It is divided into two or more petals to facilitate the stacking and pressing of silicon steel sheets. These petals usually have a conical or stepped structure to facilitate the positioning and pressing of silicon steel sheets. The tightly fitted silicon steel sheets can reduce eddy current losses and improve the efficiency of the equipment.

[0003] Chinese Patent Publication No. CN206210597U, entitled "An Annealing Clamping Device for Silicon Steel Cores," includes a rectangular core fixing frame composed of an upper pressure plate, a lower pressure plate, and a side plate between the upper and lower pressure plates, which places the core fixing frame on a workbench. A side baffle is vertically mounted on the workbench on one side of the core fixing frame, and a support frame is connected to the outer surface of the side baffle. A hydraulic actuator is mounted on the other side of the core fixing frame, and a thrust plate is connected to the hydraulic actuator, which contacts the side plate of the core fixing frame on that side. A second hydraulic actuator is mounted above the upper pressure plate of the core fixing frame, and a second thrust plate is connected to the hydraulic actuator, which contacts the upper pressure plate of the core fixing frame. This invention not only ensures good straightness of the end faces of the wound core into a square shape, but also improves the forming efficiency by at least 10%. It has a simple structure and is easy to implement.

[0004] The shortcomings of the above solution are as follows: although the solution can improve the flatness of the end face, the device cannot be adjusted during use, the pressing pressure may not be evenly distributed on the entire silicon steel core, resulting in irregular geometry of the core and inability to maintain stability. The pressing process may require frequent adjustments and calibrations, which will reduce production efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide a steel core pressing device to solve the technical problems in the prior art, such as the inability to adjust the device during use, the possibility that the pressing pressure may not be evenly distributed on the entire silicon steel core, resulting in irregular geometry of the core and inability to maintain stability, and the need for frequent adjustments and calibrations during the pressing process, which reduces production efficiency.

[0006] The technical problem to be solved by this utility model can be achieved through the following technical solution:

[0007] A steel core pressing device includes a base plate;

[0008] Two sets of slide rails are connected to the base plate. A slider is slidably connected to each set of slide rails. A support frame is connected to the end of the slider away from the slide rail. A mounting plate is connected to the support frame. A slide groove is connected to the mounting plate. An adjusting block is slidably connected in the slide groove. A vertical adjustment mechanism is connected between the adjusting block and the mounting plate.

[0009] Two pressing frames are slidably connected to the base plate, and a lateral adjustment mechanism is connected between the two pressing frames. The lateral adjustment mechanism includes a fixing block, a sliding rod connected to the fixing block, a sliding ring slidably connected to the sliding rod, and sliding blocks connected to the ends of the two pressing frames. A rotating shaft is connected to the end of the sliding block away from the pressing frame, a connecting shell is connected to the rotating shaft, and a connecting rod is connected to the side of the connecting shell away from the rotating shaft. The end of the connecting rod away from the rotating shaft is connected to the slip ring.

[0010] As a further embodiment of this utility model, the support frame is a U-shaped structure.

[0011] As a further embodiment of this utility model, the support frame is an aluminum alloy structure.

[0012] As a further embodiment of this utility model: the vertical adjustment mechanism includes a gear and a rack, a drive motor is connected to the mounting plate, the gear is connected to the drive end of the drive motor, the rack is meshed with one side of the gear, the rack is connected to the adjustment block, and a pressing mold is connected to the bottom of the adjustment block.

[0013] As a further embodiment of this utility model: one end of the adjusting block pressing mold is connected to a limit block.

[0014] As a further embodiment of this utility model, the press mold is an alloy steel structure.

[0015] As a further embodiment of this utility model, the press-fit frame is an alloy steel structure.

[0016] As a further embodiment of this utility model: the end of the slide rod away from the fixed block is connected to a limiting head.

[0017] As a further aspect of this invention, a lubricant is applied between the slip ring and the slide rod.

[0018] As a further embodiment of this utility model, the slip ring and the slide rod are detachably connected by a plug bolt.

[0019] The beneficial effects of this utility model are:

[0020] 1. This utility model connects to the mounting plate via a vertical adjustment mechanism. The rotation of the gear drives the meshing rack to move. The rack slides in the groove, and the rack drives the connected adjustment block to move up and down. The adjustment block drives the pressing mold to move up and down, thereby driving the pressing mold to perform the pressing operation. The pressing mold is used to press silicon steel cores. Through the vertical adjustment mechanism, the pressing mold can be quickly adjusted to different pressing positions, improving pressing efficiency and reducing production time. The pressing mold can be adjusted according to silicon steel cores of different specifications, so that the same pressing device can adapt to the pressing needs of various iron cores.

[0021] 2. In this utility model, two pressing frames are slidably connected to the base plate. They are connected by a lateral adjustment mechanism, which includes a fixed block and a sliding rod. A sliding ring moves on the sliding rod, causing the sliding ring to drive the connecting rod to slide. The connecting rod drives the connecting shell to move, thereby pushing the sliding block to slide and the pressing frame to move, thus adjusting the position of the pressing frame. When the silicon steel core needs to be pressed, the adjusting block and the pressing mold are adjusted to the appropriate position. The lateral adjustment mechanism can accurately adjust the position of the pressing frame to ensure that the silicon steel core is in the correct position during the pressing process, thus guaranteeing the geometry and performance of the core.

[0027] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1-3As shown, a steel core pressing device includes a base plate 1. Two sets of slide rails 10 are connected to the base plate 1. A slider 12 is slidably connected to each of the two sets of slide rails 10. A support frame 13 is connected to the end of each slider 12 away from the slide rail 10. The support frame 13 has a U-shaped structure and is made of aluminum alloy. A mounting plate 18 is connected to the support frame 13. A sliding groove 17 is connected to the mounting plate 18. An adjusting block 14 is slidably connected within the sliding groove 17. A vertical adjustment mechanism is connected between block 14 and mounting plate 18. The vertical adjustment mechanism includes a gear 16 and a rack 15. A drive motor is connected to the mounting plate 18. The gear 16 is connected to the drive end of the drive motor. The rack 15 is meshed with one side of the gear 16 and connected to the adjustment block 14. A pressing mold 19 is connected to the bottom of the adjustment block 14. A limit block is connected to one end of the pressing mold 19. The pressing mold 19 is an alloy steel structure.

[0029] Two pressing frames 11 are slidably connected to the base plate 1. The pressing frames 11 are made of alloy steel. A lateral adjustment mechanism is connected between the two pressing frames 11. The lateral adjustment mechanism includes a fixing block 9. A sliding rod 7 is connected to the fixing block 9. A limit head 8 is connected to the end of the sliding rod 7 away from the fixing block 9. A sliding ring 6 is slidably connected to the sliding rod 7. Lubricant is applied between the sliding ring 6 and the sliding rod 7. A plug bolt is detachably connected between the sliding ring 6 and the sliding rod 7. A sliding block 2 is connected to each end of the two pressing frames 11. A rotating shaft 4 is connected to the end of the sliding block 2 away from the pressing frame 11. A connecting shell 3 is connected to the rotating shaft 4. A connecting rod 5 is connected to the side of the connecting shell 3 away from the rotating shaft 4.

[0030] The working principle of this utility model is as follows: The support frame 13 is fixed on the base plate 1 to support the entire device. The mounting plate 18 is mounted on the support frame 13 and has a sliding groove 17. The adjusting block 14 slides in the sliding groove 17 and is connected to the mounting plate 18 through a vertical adjustment mechanism. The gear 16 rotates to drive the meshing rack 15 to move. The rack 15 slides in the sliding groove 17 and drives the connected adjusting block 14 to move up and down. The adjusting block 14 drives the pressing mold 19 to move up and down, thereby driving the pressing mold 19 to perform the pressing operation. The pressing mold 19 is used to press the silicon steel core.

[0031] Two pressing frames 11 are slidably connected to the base plate 1. They are connected by a lateral adjustment mechanism, which includes a fixed block 9 and a sliding rod 7. The sliding ring 6 moves on the sliding rod 7, causing the sliding ring 6 to drive the connecting rod 5 to slide. The connecting rod 5 drives the connecting shell 3 to move, thereby pushing the sliding block 2 to slide and the pressing frame 11 to move, thus adjusting the position of the pressing frame 11. When the silicon steel core needs to be pressed, the adjusting block 14 and the pressing mold 19 are adjusted to the appropriate position.

[0032] The operator places the iron core between two pressing frames 11, and then drives the adjusting block 14 and pressing mold 19 downwards via the drive motor to press the iron core. The lateral adjustment mechanism ensures that the pressing frame 11 can be correctly aligned with the iron core, ensuring pressing accuracy. The connecting shell 3 and connecting rod 5 are used to connect and fix the pressing frame 11, as well as to connect with the slip ring 6. Through the above mechanism, the precise pressing of the silicon steel core is achieved, ensuring that the size and shape of the iron core meet the requirements, and improving the performance and efficiency of the motor and transformer.
