Description

Technical Field

[0001] This invention relates to the field of motor lamination equipment technology, specifically to a motor lamination manufacturing apparatus and method. Background Technology

[0002] A stamping press is essentially a stamping press. In national production, stamping technology is increasingly widely used due to its advantages over traditional machining: saving materials and energy, high efficiency, lower operator skill requirements, and the ability to produce products that cannot be achieved through machining using various molds. Stamping production is primarily for sheet metal. Through molds, blanking, punching, forming, deep drawing, trimming, fine blanking, shaping, riveting, and extrusion parts can be produced, finding wide application in various fields. For example, many components such as switches and sockets, cups, cabinets, plates, computer cases, and even missiles and aircraft can be produced using stamping presses and molds. The design principle of a stamping press is to convert circular motion into linear motion. The main motor drives a flywheel, which, through a clutch, drives gears, a crankshaft (or eccentric gear), and connecting rods to achieve the linear motion of the slide block. The motion from the main motor to the connecting rod is circular motion.

[0003] Because the punching machine requires manual placement of the entire material under the punching blade during operation, and manual removal of the punched material after punching, the material is then moved again for another cut based on experience. Some small punching machines have a simpler structure and intermittent punching time, requiring the operator to remove the material during the intervals. If an error occurs during operation, it may cause injury to the operator or damage to the material, affecting its use. Summary of the Invention

[0013] Preferably, the fixing structure includes a hydraulic rod, a motor, a toothed plate, a U-shaped block, a support plate, a feeding block, and a support rod.

[0015] S1: When using the device, the user can place the external feeding equipment on one side of the guide groove. The feeding equipment will push the raw material pieces to be stamped from one side of the guide groove one by one. After the raw material pieces are placed, the user pushes the handle. The handle drives the rotating block to control the push block to rotate around the point where it is connected to the fixed block. The push block will drive the partition to move along the moving groove, allowing the raw material pieces to enter the guide groove one by one. When the raw material pieces in the guide groove move one by one until they move to the front of the feeding block, the hydraulic rod can be activated. The hydraulic rod will push the raw material pieces into the U-shaped block through the feeding block, which is exactly below the stamping knife. The cut raw material pieces will be controlled by the motor to start the control tooth plate while the stamping knife is raised, pushing the waste back into the guide groove so that the new raw material pieces can squeeze it out. Then, the new raw material pieces can be stamped. The waste can be collected uniformly through the slide.

[0016] S2: When stamping raw material sheets, after the machine body is turned on, the machine body controls the stamping plate to move downward. The stamping plate drives the pressing sleeve to move downward. The pressing sleeve drives the connecting seat, pre-pressing block and stamping knife to move downward. During the continuous downward movement, the bottom of the pre-pressing block first contacts the top of the U-shaped block. When the bottom of the pre-pressing block touches the plate surface, the pressing sleeve will continue to move downward. By compressing the folding elastic rod, an elastic extrusion force is applied to the pre-pressing block. The pressing sleeve continues to move downward and the stamping knife contacts the plate surface. As the extrusion force increases, the stamping knife will rotate along the inclined groove through the linkage column. At the same time as the rotation, the limit spring is compressed. The rotating punching knife can then punch the raw material sheet.

[0017] S3: During the punching process, after the punching knife punches a certain distance, the outer pressure bar will also come into contact with the surface of the flame-retardant plate due to the downward punching force and move upward under force. After the pressure bar is under force, it will drive the moving frame to move vertically upward along the slide rail. The moving frame will drive the pressure teeth to move upward and compress the fixed spring. When the extrusion is over, the fixed spring will control the moving frame to return to the initial position. The moving frame will drive the pressure teeth to move upward and drive the power wheel to rotate. After the power wheel is under force, it will drive the central shaft to rotate. The central shaft controls the rotation of the two friction wheels through the linkage belt. Because the residual material after punching will enter the interior of the punching knife under strong pressure, when the number of punched plates reaches a certain bottom, the residual material inside the punching knife will gradually increase. The residual material will move upward due to continuous accumulation. The uppermost residual material will reach the inclined block and become inclined. After becoming inclined, it can push the residual material inside the punching knife out in conjunction with the rotating friction wheel.

[0018] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0019] (1) The machine body is equipped with a stamping structure. The stamping structure can control the rotation of the friction wheel through the cooperation between the moving frame and the power wheel to discharge the residual material in the cavity of the stamping knife. There is no need for manual cleaning. When the residual material inside the stamping knife accumulates more and more, the top residual material can be changed from horizontal to oblique, so that the residual material is tilted and loosened and faces the discharge port. The friction wheel can be controlled to rotate with the power wheel to move the top residual material out of the discharge port. In this way, the stamping knife can discharge the residual material while stamping, which improves the working efficiency. The stamping structure can also make the stamping knife rotate when it is under pressure by pressing the sleeve and the connecting seat, changing the straight up and down punching method of the stamping knife, which can effectively This design avoids the problem of damaged cut edges caused by the direct pressing of the punching cutter on the raw material sheet by the stamping equipment. When the punching cutter presses down, the pressure provides a rotational force to the punching cutter. This rotational force allows the punching cutter to rotate and cut downwards, resulting in a smoother cut and better cutting. A limit spring is installed inside the pressing sleeve. After the punching is completed, the limit spring can control the punching cutter to return to its original position through its own rebound force, without affecting secondary use. A pre-pressing block is also installed on the pressing sleeve. The pre-pressing block can provide a pressing and clamping force to the raw material sheet in advance when the punching cutter contacts the raw material sheet. The pre-pressing block can reduce the deformation of the raw material sheet caused by the small area of ​​pressing during punching by its large contact surface.

[0020] (3) The machine body is also equipped with a feeding structure and a fixing structure. The feeding structure can be used in conjunction with the fixing structure. The feeding structure can feed the raw material pieces one by one through the cooperation between the rotating block and the partition. The fixing structure can push, press and unpress the raw material pieces and then unload them. This allows the punching machine to form a complete feeding, pressing and unloading operation. It does not require manual control of the movement of the raw material pieces or collection of the raw material pieces. This makes the production of raw material pieces more efficient and safer. It avoids the need to manually place the whole material under the punching knife and manually remove the material after punching. Operational errors may cause injury to the operator or damage to the material and affect its use. Attached Figure Description

[0045] S1: When using the device, the user can place the external feeding equipment on one side of the guide groove 601, allowing the feeding equipment to push the raw material sheets to be stamped sequentially from one side of the guide groove 601. After placing the raw material sheets, the user pushes the handle 602. The handle 602 drives the rotating block 603 to control the push block 604 to rotate around the point of rotational connection with the fixed block 605. The push block 604 will drive the partition 606 to move along the moving groove, allowing the raw material sheets to enter the guide groove 601 one by one. When the raw material sheets in the guide groove 601 move sequentially... The process continues until the material moves to the front of the feeding block 906. At this point, the hydraulic rod 901 can be activated, and the hydraulic rod 901 will push the raw material sheet into the U-shaped block 904 through the feeding block 906, which is directly below the stamping knife 805. After the raw material sheet is cut, the motor 902 will start the control tooth plate 903 to push the waste back into the guide groove 601 so that the new raw material sheet can squeeze it out. Then, the stamping of new raw material sheets can continue. The waste can be collected uniformly through the slide 5.

[0046] S2: When stamping the raw material sheet, after the machine body 1 is turned on, the machine body 1 will control the stamping plate 7 to move downward. The stamping plate 7 drives the pressing sleeve 806 to move downward. The pressing sleeve 806 drives the connecting seat 811, the pre-pressing block 801 and the stamping knife 805 to move downward. During the continuous downward movement, the bottom of the pre-pressing block 801 first contacts the top of the U-shaped block 904. When the bottom of the pre-pressing block 801 touches the plate surface, the pressing sleeve 806 will continue to move downward. By compressing the folding elastic rod 804, an elastic extrusion force is applied to the pre-pressing block 801. The pressing sleeve 806 continues to move downward and the stamping knife 805 contacts the plate surface. As the extrusion force increases, the stamping knife 805 will rotate along the inclined groove through the linkage column 802. At the same time, the rotation compresses the limit spring 814. The rotating punching knife 805 can complete the punching of the raw material sheet.

[0047] S3: During the punching process, after the punching knife 805 punches a certain distance, the outer pressure rod 815 will also contact the surface of the flame-retardant plate due to the downward punching force and move upward under force. After being subjected to force, the pressure rod 815 will drive the moving frame 810 to move vertically upward along the slide rail 813. The moving frame 810 will drive the pressure tooth 820 to move upward and compress the fixing spring 812. When the extrusion is completed, the fixing spring 812 will control the moving frame 810 to return to the initial position. The moving frame 810 drives the pressure tooth 820 to move upward, which will drive the power wheel 809 to rotate. When the power wheel 809 is subjected to force, it will drive the central shaft 818 to rotate. The central shaft 818 controls the rotation of the two friction wheels 817 through the linkage belt 816. Because the residual material after punching will enter the interior of the stamping knife 805 under strong pressure, when the number of stamped plates reaches a certain bottom, the residual material inside the stamping knife 805 will gradually increase. The residual material will move upward due to continuous accumulation. The uppermost residual material will reach the inclined block and become inclined. After becoming inclined, it can push the residual material inside the stamping knife 805 out in conjunction with the rotating friction wheel 817.

[0048] The working principle and usage process of this invention: When using the device, the user can place the external feeding equipment on one side of the guide groove 601, allowing the feeding equipment to push the raw material sheets to be stamped sequentially from one side of the guide groove 601. After placing the raw material sheets, the user pushes the handle 602. The handle 602 drives the rotating block 603 to control the push block 604 to rotate around the point of rotational connection with the fixed block 605. The push block 604 will drive the partition 606 to move along the moving groove, allowing the raw material sheets to enter the guide groove 601 one by one. When the raw material sheets in the guide groove 601 move sequentially until they reach the front of the feeding block 906, the hydraulic rod 901 can be activated. The hydraulic rod 901 will then push the raw material sheets into the U-shaped block 904 through the feeding block 906, precisely... Directly below the stamping cutter 805, the cut material sheet is controlled by motor 902 to start the control toothed plate 903 as the stamping cutter 805 is raised, pushing the waste back into the guide groove 601 so that the new material sheet can squeeze it out. Then, the stamping of new material sheets continues. The waste can be collected uniformly through the slide 5. When stamping the material sheet, after the machine body 1 is turned on, the machine body 1 will control the stamping plate 7 to move downward. The stamping plate 7 drives the pressing sleeve 806 to move downward. The pressing sleeve 806 drives the connecting seat 811, the pre-pressing block 801 and the stamping cutter 805 to move downward. During the continuous downward movement, the bottom of the pre-pressing block 801 first contacts the top of the U-shaped block 904. When the bottom of the pre-pressing block 801 touches the plate surface, the pressing sleeve... The cylinder 806 continues to move downwards, applying an elastic extrusion force to the pre-pressing block 801 through the compression and folding elastic rod 804. The pressing sleeve 806 continues to move downwards, and the punching knife 805 contacts the surface of the plate. As the extrusion force increases, the punching knife 805 rotates along the inclined groove via the linkage column 802. Simultaneously, the rotation compresses the limit spring 814. The rotating punching knife 805 can then punch the raw material sheet. During the punching process, after the punching knife 805 punches a certain distance, the outer pressure rod 815 will also contact the surface of the flame-retardant plate due to the downward punching force and move upwards under pressure. After being subjected to force, the pressure rod 815 will drive the moving frame 810 to move vertically upwards along the slide rail 813. The moving frame 810 will then drive the pressure tooth 820 to move upwards and press... The fixed spring 812 controls the moving frame 810 to return to its initial position after the extrusion is completed. The moving frame 810 drives the pressure tooth 820 to move upward, which in turn drives the power wheel 809 to rotate. The power wheel 809, under pressure, drives the central shaft 818 to rotate. The central shaft 818 controls the rotation of the two friction wheels 817 through the linkage belt 816. Because the residual material after punching will enter the interior of the stamping knife 805 under strong pressure, when the number of stamped plates reaches a certain bottom, the residual material inside the stamping knife 805 will gradually increase. The residual material will move upward due to continuous accumulation. The uppermost residual material will reach the inclined block and become inclined. After becoming inclined, it can push the residual material in the stamping knife 805 out in conjunction with the rotating friction wheel 817.

8. The method for manufacturing motor laminations according to claim 1, characterized in that: The operational process steps are as follows: S1: When using the device, the user can place the external feeding equipment on one side of the guide groove (601), allowing the feeding equipment to push the raw material sheets to be stamped sequentially from one side of the guide groove (601). After placing the raw material sheets, the user pushes the handle (602). The handle (602) drives the rotating block (603) to control the push block (604) to rotate around the rotating connection point with the fixed block (605). The push block (604) will drive the partition (606) to move along the moving groove, allowing the raw material sheets to enter the guide groove (601) one by one. When the raw material sheets in the guide groove (601) move sequentially... The material is moved until it moves to the front of the feeding block (906). At this time, the hydraulic rod (901) can be activated. The hydraulic rod (901) will push the raw material sheet into the U-shaped block (904) through the feeding block (906) and it is exactly below the stamping knife (805). The cut raw material sheet will be controlled by the motor (902) to start the control tooth plate (903) while the stamping knife (805) is raised. The waste material will be pushed back into the guide groove (601) so that the new raw material sheet can squeeze it out. Then, the new raw material sheet can be stamped. The waste material can be collected uniformly through the slide (5). S2: When stamping the raw material sheet, after the machine body (1) is turned on, the machine body (1) will control the stamping plate (7) to move downward. The stamping plate (7) drives the pressing sleeve (806) to move downward. The pressing sleeve (806) drives the connecting seat (811), the pre-pressing block (801) and the stamping knife (805) to move downward. During the continuous downward movement, the bottom of the pre-pressing block (801) will first contact the top of the U-shaped block (904). When the bottom of the pre-pressing block (801) touches the plate surface, The pressing sleeve (806) will continue to move downwards, and apply an elastic extrusion force to the pre-press block (801) by compressing the folding elastic rod (804). The pressing sleeve (806) continues to move downwards and the punch (805) contacts the surface of the plate. As the extrusion force increases, the punch (805) will rotate along the inclined groove through the linkage column (802). At the same time as the rotation, the limiting spring (814) is compressed. The rotating punch (805) can punch the raw material sheet. S3: During the punching process, after the punching knife (805) punches to a certain distance, the outer pressure rod (815) will also come into contact with the surface of the flame-retardant plate due to the downward punching force and move upward under force. After the pressure rod (815) is under force, it will drive the moving frame (810) to move vertically upward along the slide rail (813). The moving frame (810) will drive the pressure tooth (820) to move upward and compress the fixing spring (812). When the extrusion is over, the fixing spring (812) will control the moving frame (810) to return to the initial position. The moving frame (810) will drive the pressure tooth (820) to move upward, which will drive the power wheel (809) to move upward. When the power wheel (809) is subjected to force, it will drive the central shaft (818) to rotate. The central shaft (818) controls the rotation of the two friction wheels (817) through the linkage belt (816). Because the residual material after punching will enter the interior of the stamping knife (805) under strong pressure, when the number of stamped plates reaches a certain bottom, the residual material inside the stamping knife (805) will gradually increase. The residual material will move upward due to continuous stacking. The uppermost residual material will reach the inclined block and become inclined. After becoming inclined, it can push the residual material inside the stamping knife (805) out in conjunction with the rotating friction wheel (817).
