Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, and in particular to a multi-blade simultaneous punching device for a transformer core cross-cutting production line. Background Technology

[0002] Transformer core production equipment, both domestically and internationally, uses cross-cutting lines. Traditional cross-cutting lines arrange the cutting mechanism along the direction of the strip's movement (longitudinal). The program is written according to the core sheet type, and the strip is fed to the corresponding cutting mechanism via feeding rollers. Then, feeding is stopped and cutting resumes, i.e., a stop-cutting process. Corresponding start and stop strip operations are required for each cutting mechanism, resulting in low production efficiency.

[0003] Publication No. CN113102601A discloses a forming and punching machine and method for transformer silicon steel sheet assemblies, including a base, a winding device, an extrusion device, a rolling device, and a stamping device. Vertical rods are fixedly connected to the upper end of the base at each of the four corners. A horizontal plate is connected to the upper end of the vertical rods. The stamping device is located at the lower end of the horizontal plate. The winding device is located at the upper end of the base. An extrusion device is located behind the winding device at the upper end of the base. A rolling device is located behind the extrusion device at the upper end of the base. By pulling a pull ring, a circular plate and a push rod are driven to compress a first spring. The compression of the first spring causes the push rod to move away from the push groove, allowing the mold to be removed and replaced. A placement plate is added into the groove to support the mold when the pressure plate impacts it, preventing mold deformation. This structure cannot achieve simultaneous multi-blade punching. Utility Model Content

[0004] To overcome the problem of low production efficiency in existing production lines, this invention provides a multi-blade simultaneous punching device for a transformer core shearing production line. This invention uses a punching mechanism and a V-punching mechanism to move automatically along the longitudinal direction, and combines the shear 1 to achieve pre-positioning of different sheet types, enabling three configuration schemes and achieving up to 5 blades of simultaneous punching. That is, where the existing side yoke sleeve cutting requires 6 stops to complete, it can now be completed in only 2 stops, effectively improving the production efficiency of the production line.

[0005] The technical solution adopted in this utility model is as follows: A multi-blade simultaneous punching device for a transformer core cross-cutting production line includes a control system, a frame, a punching mechanism, a V-punching mechanism, a material guide rail, a material support unit, and a width adjustment mechanism. The punching mechanism and the V-punching mechanism both move longitudinally on the frame via corresponding linear guide rails one and two. The punching mechanism and the V-punching mechanism are located on both sides of the material guide rail. The width adjustment mechanism is located on the frame and connected to the material guide rail closest to the V-punching mechanism. Multiple material support units are located below the center of the material guide rail. The control system is electrically connected to the punching mechanism, the V-punching mechanism, the width adjustment mechanism, and the material support units.

[0006] The linear guide rail one and linear guide rail two are arranged parallel to each other along the longitudinal direction of the frame.

[0007] The aforementioned punching mechanism comprises multiple punching mechanisms, which are driven by a gear drive unit to move on a linear guide rail.

[0008] The gear drive unit includes a gear, a rack, and a motor. The motor drives the gear, causing the punching mechanism to move on the rack. The motor is electrically connected to the control system.

[0009] The material guide rail includes a linear guide rail and a segmented guide rail. The punching mechanism is located on the side closer to the linear guide rail, and the V-punching mechanism is located on the side closer to the segmented guide rail.

[0010] The segmented guide rail includes a crossbeam and segmented material support units. The segmented material support units are multiple units that are evenly distributed longitudinally on the crossbeam. The crossbeam has connecting plates at both ends, and the connecting plates are hinged to the width adjustment mechanism.

[0011] The segmented material support unit has the same structure as the material support unit. The material support unit includes a fixed block, a material support plate, a connector, a nut, a stud, and a cylinder. The fixed block is a triangular block, and its bottom surface is fixed on the connector. The connector is connected to the cylinder. The fixed block has a nut on its side, and a stud is provided on the nut. The material support plate is connected to the top of the stud. The cylinder is connected to the control system via electrical signals.

[0012] The cylinder is a cylinder with a guide rod.

[0013] The fixing blocks consist of two pieces, symmetrically arranged on the connector.

[0014] The V-punch mechanism is driven to move on the linear guide rail two by a lead screw drive unit.

[0015] The beneficial effects of this utility model are: This invention enables automatic longitudinal movement of the punching mechanism and V-punching mechanism, combined with the shear 1 to achieve pre-positioning of different sheet types, and can realize three configuration schemes. Up to 5 blades can be punched simultaneously, that is, the existing set of edge yoke sleeve cutting requires 6 stops of shearing to complete, but now it can be completed in only 2 times, which effectively improves the production efficiency of the production line.

[0022] 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, 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.

[0023] The accompanying drawings show various structural schematic diagrams according to embodiments of the present invention. These drawings are not to scale, and some details have been enlarged and may have been omitted for clarity. The shapes of the various regions and layers shown in the drawings, as well as their relative sizes and positional relationships, are merely exemplary and may deviate from reality due to manufacturing tolerances or technical limitations. Furthermore, those skilled in the art can design regions / layers with different shapes, sizes, and relative positions as needed.

[0024] Example 1: To overcome the problem of low production efficiency in existing systems, this utility model provides the following... Figures 1-5 The present invention discloses a multi-blade simultaneous punching device for a transformer core cross-cutting production line. The present invention uses a punching mechanism and a V-punching mechanism to move automatically along the longitudinal direction. Combined with the shear 1, different sheet types are pre-positioned, and three configuration schemes can be realized. Up to 5 blades can be punched simultaneously. That is, the existing set of edge yoke sleeve cutting requires 6 stops to complete, but now it can be completed in only 2 times, which effectively improves the production efficiency of the production line.

[0025] A multi-blade simultaneous punching device for a transformer core cross-cutting production line includes a control system, a frame 1, a punching mechanism 2, a V-punch mechanism 3, a material guide rail 5, a material support unit 9, and a width adjustment mechanism 7. The punching mechanism 2 and the V-punch mechanism 3 move longitudinally on the frame 1 via corresponding linear guide rails 4 and 6. The punching mechanism 2 and the V-punch mechanism 3 are located on both sides of the material guide rail 5. The width adjustment mechanism 7 is located on the frame 1 and connected to the material guide rail 5 closest to the V-punch mechanism 3. Multiple material support units 9 are located below the center of the material guide rail 5. The control system is electrically connected to the punching mechanism 2, the V-punch mechanism 3, the width adjustment mechanism 7, and the material support unit 9.

[0026] like Figure 1 , Figure 2 and Figure 3 As shown, in this invention, the material support unit 9 is inclined. When material support is required, the control system controls the cylinder 906 of the material support unit 9 to operate, raising the material support plate 902 to support the bottom of the strip. This supports the strip during punching by the punching mechanism 2 and the V-punch mechanism 3, preventing the strip from bending.

[0027] In this invention, the punching mechanism 2 moves longitudinally on linear guide rail 4, and the V-punching mechanism 3 moves longitudinally on linear guide rail 6. The material guide rail 5 is connected to the frame 1 at both ends via a width adjustment mechanism 7, which moves laterally on the frame 1. The material guide rail 5 is located above linear guide rail 4 and linear guide rail 6, such that the V-punching mechanism 3 and the punching mechanism 2 are located on opposite sides of the material guide rail 5. The material guide rail 5, linear guide rail 4, and linear guide rail 6 are all longitudinally distributed on the frame 1, and the width adjustment mechanism 7 moves laterally at both ends of the frame 1.

[0028] When this utility model is in use, if the punching mechanism 2 and the V-punch mechanism 3 are punching simultaneously, the multiple punching mechanisms 2 are moved to the position where punching is required. At this time, the material support unit 9 below the position of the punching mechanism 2 does not rise, so as not to affect the punching operation of the punching mechanism 2. The V-punch mechanism 3 is moved to the position where V holes need to be punched. The V-punch mechanism 3 is located on one side of the segmented guide rail of the material guide rail 5. When punching, the segmented material support unit 15 of the segmented guide rail at the position of the V-punch mechanism 3 does not rise, while the segmented material support units 15 at other positions all rise to support the material. This ensures that the V-punch mechanism 3 will not punch the segmented guide rail when punching downwards.

[0029] This utility model uses the punching mechanism 2 and the V-punching mechanism 3 to move automatically along the longitudinal direction, and combined with the shear 1 to achieve pre-positioning of different piece types, which can realize three configuration schemes and achieve up to 5 simultaneous punching. That is, the existing set of edge yoke cutting requires 6 stops of shearing to complete, but now it can be completed in only 2 times, which effectively improves the production efficiency of the production line.

[0030] Example 2: Based on Embodiment 1, in this embodiment, preferably, the linear guide rail 4 and the linear guide rail 6 are arranged parallel to each other on the longitudinal direction of the frame 1.

[0031] Preferably, there are multiple punching mechanisms 2, and the multiple punching mechanisms 2 are driven by the gear drive unit 11 to move on the linear guide rail 4.

[0032] Preferably, the gear drive unit 11 includes a gear 1101, a rack 1102, and a motor 1103. The motor 1103 drives the gear 1101, causing the punching mechanism 2 to move on the rack 1102. The motor 1103 is electrically connected to the control system.

[0033] In this invention, three punching mechanisms 2 are preferably used. The longitudinal movement of the punching mechanisms 2 is driven by a gear drive unit 11, that is, by a gear and rack transmission. In this invention, the three punching mechanisms 2 share a set of racks 1102, and the gears 1101 are fixed on each punching mechanism 2 respectively.

[0034] Preferably, the material guide rail 5 includes a linear guide rail and a segmented guide rail, the punching mechanism 2 is located on the side closer to the linear guide rail, and the V-punching mechanism 3 is located on the side closer to the segmented guide rail.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, in this invention, both sides of the linear guide rail and the segmented guide rail are connected to the width adjustment mechanism 7 corresponding to both sides. The lower end of the linear guide rail is connected to the width adjustment mechanism 7 via a cross slider 12, meaning the linear guide rail can move laterally with the width adjustment mechanism 7 and also provides support when the punching mechanism 2 moves longitudinally. The width adjustment mechanism 7 is a mature existing technology. It adjusts the distance between the linear guide rail and the segmented guide rail to accommodate strips of various widths. During adjustment, the width adjustment mechanism 7 moves on the width adjustment slide rail 13.

[0036] Preferably, the segmented guide rail includes a crossbeam 8 and segmented material support units 15. The segmented material support units 15 are multiple units that are evenly distributed longitudinally on the crossbeam 8. The crossbeam 8 has connecting plates 14 at both ends, and the connecting plates 14 are hinged to the width adjustment mechanism 7.

[0037] Preferably, the segmented material support unit 15 has the same structure as the material support unit 9. The material support unit 9 includes a fixing block 901, a material support plate 902, a connector 903, a nut 904, a stud 905, and a cylinder 906. The fixing block 901 is a triangular block, and its bottom surface is fixed on the connector 903. The connector 903 is connected to the cylinder 906. The fixing block 901 has a nut 904 on its side, and a stud 905 is provided on the nut 904. The material support plate 902 is connected to the top of the stud 905. The cylinder 906 is connected to the control system via electrical signals.

[0038] In this utility model, the height of the material support plate 902 is determined by the nut 904 and the stud 905.

[0039] Preferably, the cylinder 906 is a cylinder with a guide rod.

[0040] In this invention, the cylinder with guide rod can lift and retract the material support plate 902.

[0041] Preferably, the fixing block 901 consists of two blocks, symmetrically arranged on the connector 903.

[0042] Preferably, the V-jet mechanism 3 is driven to move on the linear guide rail 6 by the lead screw drive unit 10.

[0043] In this utility model, there are multiple material support units 9, and each material support unit 9 is driven to rise and fall by a corresponding cylinder 906. According to different punching configuration schemes, the material support unit 9 can rise and fall according to the program design requirements. That is, when the punching mechanism 2 is directly above it, the corresponding material support plate 902 falls to avoid interference with the punching mechanism 2 above it; otherwise, it rises to play the role of supporting material.

[0044] In this utility model, the longitudinal movement of the V-punch mechanism 3 is driven by a lead screw drive unit 10.

[0045] In this utility model, the punching mechanism 2, the V-punch mechanism 3, the gear drive unit 11, and the lead screw drive unit 10 are all existing mature technologies, and will not be further described in this utility model.

[0046] In this utility model, a floating segmented guide rail is arranged on the lower side of the longitudinal moving slide of the V-punch mechanism 3. The connecting plate 14 at the crossbeam 8 of the segmented guide rail is hinged to the width adjustment mechanism 7 on both sides of the V-punch mechanism 3. The segmented guide rail distributed on the crossbeam 8 moves laterally with the width adjustment mechanism 7.

[0047] In this utility model, there are multiple segmented material support units 15. Each segmented material support unit 15 is driven to lift by a corresponding cylinder. According to different punching configuration schemes, the segmented material support unit 15 can be raised and lowered according to design requirements. That is, when the V-punch mechanism 3 is directly above it, the segmented material support unit 15 is lowered to avoid interference with the V-punch mechanism 3 above it; otherwise, it is raised to play the role of guiding material.

[0048] In this invention, the segmented material support unit 15 is fixed on the crossbeam 8 and supports the edge of the material. The material support unit 9 is fixed on the frame 1 and its function is to support the middle of the material. The segmented material support unit 15 and the material support unit 9 have the same basic structure and the same working principle. Both use a cylinder 906 to raise and lower the material support plate 902 to support the material.

[0049] like Figure 5 As shown, Figure 5 In the diagram, (a) represents the sheet shearing model for silicon steel sheets. (b) is the blade configuration scheme I, which is from left to right: shear 1, H1, V1, H2, H3; (c) is blade configuration II, which is from left to right: shear 1, H1, H2, V1, H3; (d) is blade configuration scheme III, which is from left to right: shear 1, H1, H2, H3, V1; Different cutting schemes at the root are used to adjust the positions of the V-punching mechanism 3 and the punching mechanism 2. V1 and V2 are punched by the V-punching mechanism 3, while H1, H2, and H3 are punched by the three punching mechanisms 2. Shear 1 and Shear 2 are both shearing mechanisms, which are existing mature technologies and will not be described further in this utility model. By repeating the above-mentioned punching schemes, the required silicon steel sheet shearing model can be obtained. Each cutting scheme is one punching operation, and V2 and Shear 2 are the positions for the next punching operation.

[0050] After the blades are fitted according to the above scheme, round holes and V-holes can be punched out simultaneously. Then, shears 1 and 2 are used to cut the punched silicon steel sheets into edge pieces and yoke pieces. Finally, the sheets are fed out by the feeding roller, thus increasing the punching efficiency. This utility model automatically moves the punching mechanism 2 and V-punching mechanism 3 longitudinally, and combined with shear 1 to achieve pre-positioning of different sheet types, enabling three configuration schemes. Up to 5 blades can be punched simultaneously. That is, where the previous set of edge yoke cutting required 6 stops of shearing to complete, now it only requires 2 stops, effectively improving the production line efficiency.

[0051] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0052] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.
