Description

Technical Field

[0001] This utility model relates to the field of stamping technology, specifically a stator silicon steel sheet stamping device. Background Technology

[0002] Silicon steel sheets, also known as electrical silicon steel, are iron-silicon alloys with a silicon content between 0.5% and 4.8%. They are a widely used soft magnetic material in the electrical engineering field. Silicon steel sheets are typically rolled from standard-sized large sheets or strips and are important components in electric motors, generators, transformers, electromagnetic mechanisms, relays, electronic devices, and measuring instruments. Silicon steel sheets possess several excellent properties. Their low resistivity effectively reduces motor heating; their magnetic permeability is much higher than that of ordinary steel, and their low iron loss significantly improves the efficiency and lifespan of electrical equipment.

[0003] Stator silicon steel sheets are typically formed using stamping dies, which precisely shapes them into the required form. However, during the stamping process, the formed stator silicon steel sheets often remain inside the die, requiring manual unloading by workers. This manual unloading process is not only time-consuming but also reduces overall production efficiency to some extent. Utility Model Content

[0004] The purpose of this invention is to provide a stator silicon steel sheet stamping device to solve the problem of low production efficiency in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stator silicon steel sheet stamping device, comprising an upper mold and a lower mold, a connecting guide rod provided between the upper mold and the lower mold, a discharge groove fixedly installed on one side of the lower mold, a stamping mechanism fixedly installed at the bottom of the upper mold, a workpiece groove opened on the lower mold, a discharge mechanism provided on one side of the workpiece groove, the discharge mechanism comprising a side baffle slidably installed on the lower mold and a drive rack fixedly installed inside the lower mold, a movable shaft rotatably installed on the side baffle, a permanent magnet fixedly installed at the upper end of the movable shaft, and a drive gear fixedly installed at the lower end of the movable shaft.

[0006] Preferably, an electric push rod is fixedly installed inside the lower mold, and the output end of the electric push rod is fixed to the side baffle. A receiving cavity is opened in the side baffle, and a stator silicon steel sheet is provided in the workpiece groove.

[0007] Preferably, the movable shaft is provided with a bearing, and the movable shaft is movably mounted on the side baffle via the bearing.

[0008] Preferably, the permanent magnet is movably mounted in the receiving cavity via a movable shaft, the drive gear is movably mounted on one side of the drive rack via a movable shaft, and the drive rack meshes with the drive gear. The lower mold is provided with a sliding groove, and the side baffle is movably mounted to one side of the workpiece groove via the sliding groove.

[0009] Preferably, the stamping mechanism includes a positioning sleeve and a connecting base fixedly installed on the upper mold. A punch is fixedly installed at the bottom of the connecting base. A return spring is provided inside the positioning sleeve. A spring seat is movably installed inside the positioning sleeve. A telescopic support is fixedly installed on the spring seat. A pressure plate is fixedly installed at the lower end of the telescopic support.

[0010] Preferably, the upper mold has an installation groove, and the positioning sleeve is installed in the upper mold through the installation groove.

[0011] Preferably, the punch is mounted on the upper mold via a connecting base, the telescopic support is movably mounted inside the positioning sleeve via a spring seat, one end of the return spring is connected to the spring seat, and the other end of the return spring is connected to the upper end of the positioning sleeve.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this application, during the downward movement of the mold, the pressure plate first contacts the silicon steel sheet to fix the silicon steel sheet in the workpiece groove. Then, the mold continues to move downward, driving the punch to move downward, thereby realizing the rapid stamping of the silicon steel sheet to form the stator silicon steel sheet.

[0014] In this application, when the side baffle moves upward to above the unloading chute, the drive gear rolls along the drive rack, thereby causing the movable shaft to rotate. During the rotation, the movable shaft rotates the permanent magnet out of the receiving chamber. Once the permanent magnet is rotated out of the receiving chamber, it can attract the stator silicon steel sheet and guide it to move to the position above the unloading chute. Subsequently, under the action of gravity, the stator silicon steel sheet will detach from the permanent magnet and slide down along the unloading chute, realizing the automatic unloading process, thereby replacing the need for manual unloading and improving production efficiency.

[0021] 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.

[0022] like Figure 1 , Figure 2 and Figure 5 As shown, this utility model provides a technical solution for a stator silicon steel sheet stamping device, including an upper mold 1 and a lower mold 3. A connecting guide rod 2 is provided between the upper mold 1 and the lower mold 3. A discharge groove 4 is fixedly installed on one side of the lower mold 3. A stamping mechanism 6 is fixedly installed at the bottom of the upper mold 1. A workpiece groove 5 is opened on the lower mold 3. A discharge mechanism 7 is provided on one side of the workpiece groove 5. The stamping mechanism 6 can quickly stamp silicon steel sheets into stator silicon steel sheets 8, and the discharge mechanism 7 can replace manual labor to achieve automatic discharge, thereby improving production efficiency.

[0023] like Figure 2 and Figure 3 As shown, the stamping mechanism 6 includes a positioning sleeve 601 and a connecting base 602 fixedly installed on the upper mold 1. A punch 603 is fixedly installed at the bottom of the connecting base 602. A return spring 605 is provided inside the positioning sleeve 601. A spring seat 606 is movably installed inside the positioning sleeve 601. A telescopic support column 607 is fixedly installed on the spring seat 606. A pressure plate 604 is fixedly installed at the lower end of the telescopic support column 607. An installation groove is provided inside the upper mold 1, and the positioning sleeve 601 is installed inside the upper mold 1 through the installation groove.

[0024] Specifically, when the upper mold 1 moves downward, the pressure plate 604 will first come into contact with the silicon steel sheet, thereby pressing the silicon steel sheet into the workpiece groove 5. After the silicon steel sheet is pressed into the workpiece groove 5, the upper mold 1 can continue to move downward. When the upper mold 1 continues to move downward, it will drive the punch 603 to move downward, thereby quickly stamping the silicon steel sheet into a stator silicon steel sheet 8.

[0025] like Figure 2 and Figure 4 As shown, the unloading mechanism 7 includes a side baffle 702 slidably mounted on the lower mold 3 and a drive rack 707 fixedly mounted inside the lower mold 3. A movable shaft 705 is rotatably mounted on the side baffle 702. A permanent magnet 704 is fixedly mounted on the upper end of the movable shaft 705, and a drive gear 706 is fixedly mounted on the lower end of the movable shaft 705. An electric push rod 701 is fixedly mounted inside the lower mold 3, and the output end of the electric push rod 701 is fixed on the side baffle 702. A receiving chamber 703 is opened inside the side baffle 702. A stator silicon steel sheet 8 is provided in the workpiece groove 5. A bearing is provided on the movable shaft 705, and the movable shaft 705 is movably mounted on the side baffle 702 through the bearing.

[0026] Specifically, the electric push rod 701 can drive the side baffle 702 to move upwards towards the unloading chute 4. During the movement of the side baffle 702, the drive gear 706 will roll along the drive rack 707, thereby driving the movable shaft 705 to rotate, causing the permanent magnet 704 to be rotated out of the storage chamber 703. The permanent magnet 704 rotated out of the storage chamber 703 will attract the stator silicon steel sheet 8, driving the stator silicon steel sheet 8 to move above the unloading chute 4. The stator silicon steel sheet 8 moved above the unloading chute 4 will detach from the permanent magnet 704 under the action of gravity, causing the workpiece to fall onto the unloading chute 4 and slide down the unloading chute 4, thus achieving automatic unloading instead of manual labor.

[0027] Working principle: During use, the silicon steel sheet is placed in the workpiece groove 5. After the silicon steel sheet is placed in the workpiece groove 5, the upper mold 1 can be driven to move downward by the hydraulic cylinder. When the upper mold 1 moves downward, the pressure plate 604 will first contact the silicon steel sheet, thereby pressing the silicon steel sheet into the workpiece groove 5. After the silicon steel sheet is pressed into the workpiece groove 5, the upper mold 1 can continue to move downward. When the upper mold 1 continues to move downward, it will drive the punch 603 to move downward, thereby quickly stamping the silicon steel sheet into a stator silicon steel sheet 8. Then the hydraulic cylinder can be retracted. After the hydraulic cylinder is retracted, the upper mold 1 will move upward. Since the telescopic support column 607 is movably installed in the positioning sleeve 601 through the spring seat 606, one end of the return spring 605 is connected to the spring seat 606, and the other end of the return spring 605 is connected to the upper end of the positioning sleeve 601. Therefore, after the upper mold 1 moves upward, the return spring 605 will pull the telescopic support column 607 to return to its original position. After the hydraulic cylinder is fully retracted, the electric push rod 701 can be activated. After the electric push rod 701 is activated, This will cause the side baffle 702 to move upwards towards the unloading chute 4. Since the permanent magnet 704 is movably installed in the receiving chamber 703 via the movable shaft 705, and the drive gear 706 is movably installed on one side of the drive rack 707 via the movable shaft 705, and the drive rack 707 meshes with the drive gear 706, when the side baffle 702 moves upwards towards the unloading chute 4, the drive gear 706 will roll along the drive rack 707, thereby driving the movable shaft 705 to rotate. During the rotation process, the permanent magnet 704 will be rotated out of the storage chamber 703. The permanent magnet 704, which is rotated out of the storage chamber 703, will attract the stator silicon steel sheet 8, thereby moving the stator silicon steel sheet 8 to the top of the unloading chute 4. The stator silicon steel sheet 8, which is moved to the top of the unloading chute 4, will detach from the permanent magnet 704 under the action of gravity. After the stator silicon steel sheet 8 detaches from the permanent magnet 704, it will fall onto the unloading chute 4 and slide down the unloading chute 4, thus achieving automatic unloading instead of manual labor.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
