Description

Technical Field

[0001] The utility model relates to the technical field of copper wire processing, and particularly relates to a 3D forming die for copper wire with good forming effect. Background Technique

[0002] The main components of an electric motor include a circuit part, a magnetic circuit part, an insulating part and a structural part. In most cases, the stator and rotor cores, which are the main carriers of the magnetic field, are made of multiple layers of silicon steel sheets through a lamination process. The use of laminated cores can greatly reduce eddy current losses and improve the efficiency of energy conversion. The circuit part of the electric motor is generally enameled wire, which is embedded in the wire grooves of the stator and rotor cores. There are two types of enameled wire: round wire and flat wire. The existing copper wire needs to be 3D formed after 2D forming, and a 3D forming die is required.

[0003] In order to solve the above technical problems, the Chinese utility model patent with the authorization announcement number of CN220920738U discloses a 3D forming die for copper wire. Through the combined use of a lower die and an upper die, it is convenient for the 3D forming of the copper wire after 2D forming. By setting springs and movable blocks, the movable blocks can squeeze the copper wire pins in the wire grooves, and the structure is simple and practical.

[0004] Although the technical solution provided by this utility model achieves the purpose of 3D forming of the existing copper wire after 2D forming, the die in the above solution is not convenient for multi-directional limiting of the copper wire to be formed, which may cause the copper wire to move during forming, and further may cause the finally formed copper wire not to achieve the expected effect or shape. Content of the Utility Model

[0005] The purpose of the utility model is to provide a 3D forming die for copper wire with good forming effect to solve the problems raised in the above background technique.

A floating wire pressing component is arranged between the first upper pressing module and the second upper pressing module.

[0008] The lower die component includes a lower die fixing block, which is fixedly installed on a forming fixing table. A lower pressing module is fixedly installed on one side of the lower die fixing block facing the upper die fixing block. A limiting component for limiting the copper wire is arranged on one side surface of the lower pressing module facing the upper die fixing block.

[0023] To make the objectives, technical solutions and advantages of the present application clearer, the technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without making creative efforts shall fall within the scope of protection of the present application.

[0024] The following will detail the technical solutions provided by each embodiment of the present application with reference to the drawings.

[0025] Please refer to Figures 1-5 , a 3D forming die for copper wires with good forming effect; it includes an upper die component 1 and a lower die component 2. The upper die component 1 includes an upper die fixing block 3, and the upper die fixing block 3 is fixedly installed at the stamping end of the stamping mechanism. On both sides of one side surface of the upper die fixing block 3 facing the lower die component 2, a first upper pressing module 4 and a second upper pressing module 5 are respectively fixedly connected. A floating wire pressing assembly is arranged between the first upper pressing module 4 and the second upper pressing module 5, and the floating wire pressing assembly is fixed on the upper die fixing block 3;

[0026] The lower die component 2 includes a lower die fixing block 17, and the lower die fixing block 17 is fixedly installed on the forming fixing table. On the side of the lower die fixing block 17 facing the upper die fixing block 3, a lower pressing module 18 is fixedly installed. On one side surface of the lower pressing module 18 facing the upper die fixing block 3, a limiting assembly for limiting the copper wire is arranged;

[0027] The floating wire pressing assembly includes two connecting columns 13, both of which are fixedly installed on the lower surface of the upper die fixing block 3. A return spring 14 is sleeved on the connecting column 13. A floating module 15 is slidably connected to the two connecting columns 13. Pressing blocks 16 are fixedly connected to the front and rear sides of the lower surface of the floating module 15. The opposite sides of the two pressing blocks 16 are inclined surfaces and the two inclined surfaces are in an inverted V shape. The floating module 15 is provided with holes for the connecting columns 13 to be inserted. A convex ring is provided at the lower end of the connecting column 13, and the convex ring is larger than the holes on the floating module 15. When the floating module 15 is not under force, under the cooperation of the return spring 14 and its own gravity, it will always be at the end of the connecting column 13. Thus, during the downward pressing process, the pressing block 16 will first contact and press the copper wire, preventing the copper wire from moving during the forming process. The pressing block 16 limits and fixes the middle part of the copper wire. When the upper die part 1 and the lower die part 2 are closed, the forming is completed by the deformation of the copper wire itself. After the copper wire forming is completed, the upper die part 1 moves upward, and under the action of the return spring 14, the floating module 15 can be quickly reset to prepare for the next forming;

[0028] On one side of the first upper pressing module 4 facing the lower pressing module 18, a first support groove 7, a second support groove 8, an upper forming groove 9 and a column groove 11 are provided;

[0029] On one side of the second upper pressing module 5 facing the lower pressing module 18, two symmetrically arranged limiting blocks 10 are fixedly installed. On the second upper pressing module 5 and near the limiting blocks 10, two upper guiding grooves 12 are provided. Convex surfaces that fit the lower pressing module 18 are provided on the first upper pressing module 4, the second upper pressing module 5 and the floating module 15 to achieve the 3D forming of the copper wire;

[0030] The limiting assembly includes a first support block 19, which is fixedly installed in the middle of one side of the lower pressing module 18 facing the upper die fixing block 3. Second support blocks 20 are symmetrically arranged on both sides of the first support block 19. The second support blocks 20 are installed on the lower pressing module 18. A lower forming block 21 is fixedly installed on the lower pressing module 18 near the first support block 19. Forming columns 22 are respectively and fixedly installed on the lower pressing module 18 near the two second support blocks 20. The first support block 19, the second support blocks 20, the lower forming block 21 and the forming columns 22 can be inserted into the first support groove 7, the second support groove 8, the upper forming groove 9 and the column groove 11. The forming columns 22 and the lower forming block 21 fit the copper wire in the 2D form, preventing the copper wire from deforming during the stamping forming process. The first support block 19 and the second support blocks 20 play a certain role in supporting and limiting the copper wire during the stamping process. At the same time, a wire groove that fits the 2D form of the copper wire is provided in the lower pressing module 18;

[0031] The lower pressing module 18 is provided with two limiting grooves 25 adapted to the limiting blocks 10, and two lower guiding blocks 23 adapted to the upper guiding grooves 12 are fixedly installed on the lower pressing module 18. The lower pressing module 18 is provided with two symmetrically arranged wire pressing grooves 24, and the wire pressing grooves 24 are located between the forming columns 22 and the lower guiding blocks 23;

[0032] When the utility model is in use, first, the lower die fixing block 17 is fixedly installed on the forming fixing table through bolts, and the upper die fixing block 3 is fixedly installed on the stamping end of the stamping mechanism through bolts to prepare for the 3D forming of the copper wire;

[0033] Next, the copper wire to be 3D formed is placed in the corresponding wire groove on the lower pressing module 18. The lower guiding block 23 first preliminarily limits the span of the copper wire. During the downward movement of the upper die component 1, the wire pressing block 16 first contacts the copper wire. During the downward movement of the limiting block 10 and the wire pressing block 16, the pins placed on the lower guiding block 23 are inwardly retracted to further limit the span of the copper wire, so that the span between the two pins can fit the wire groove on the lower pressing module 18. After the wire pressing block 16 contacts the copper wire, the middle part of the copper wire is limited and fixed. When the first upper pressing module 4 and the second upper pressing module 5 are completely attached to the lower pressing module 18, the end of the copper wire is formed by the self-deformation of the copper wire under the cooperation of the lower forming block 21, the first support block 19, the second support block 20 and the forming column 22. The wire pressing block 16 presses the copper wire throughout the process to prevent the copper wire from moving and affecting the forming effect.

[0034] The above are only the embodiments of the present application and are not used to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
