Description

A composite die for stamping generator rotor laminations Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically a composite stamping die for generator rotor laminations. Background Technology

[0002] As is well known, the generator rotor is the rotating part of the generator, mainly composed of conductive rotor windings, magnetic iron core, rotor shaft extension, retaining ring, center ring and fan, etc. The conductive rotor windings include laminations and coils, and the rotor laminations need to be stamped using stamping dies.

[0003] However, existing generator rotor lamination stamping composite dies are generally fixed on the equipment, and the dies are not easy to disassemble. When it is necessary to stamp laminations of different sizes, the dies and laminations cannot be matched, causing the equipment to malfunction and reducing the practicality of the equipment. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a composite die for stamping generator rotor laminations.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a composite die for stamping generator rotor laminations, comprising a base plate, a support base, a die mechanism, and a connecting mechanism. The support base is disposed at the bottom of the base plate, and several support bases are provided. The die mechanism is connected to the base plate via the connecting mechanism. The die mechanism includes a lower die base, a groove, an upper die base, a protrusion, and a mounting block. The groove is formed on the lower die base, the protrusion is disposed on the upper die base, and the mounting block is fixedly connected to the top of the upper die base. The upper die base matches the lower die base, and the groove matches the protrusion. A through hole is provided on the base plate. The through hole penetrates the base plate. The connecting mechanism includes a sliding component, a guide post, a first guide block, a second guide block, and a limiting plate. The guide post is connected to the base plate through the sliding component. One end of the first guide block is connected to the lower mold base and is fitted onto the guide post. One end of the second guide block is connected to the upper mold base and is fitted onto the guide post. One end of the limiting plate is connected to the lower mold base, and the other end of the limiting plate extends into the base plate. A groove matching the limiting plate is provided on the base plate. A controller is provided on the front of the base plate, and the controller is electrically connected to the sliding component.

[0008] To improve stability, this utility model is improved by having several of the aforementioned support seats arranged symmetrically.

[0009] To achieve an anti-slip effect, the present invention is improved by providing an anti-slip layer at the bottom of the support base, and the anti-slip layer is fixedly connected to the bottom of the support base.

[0010] To improve the anti-slip effect, the present invention is improved by providing anti-slip textures at the bottom of the anti-slip layer, and the anti-slip textures are provided in multiple strips.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a composite die for stamping generator rotor laminations, which has the following advantages:

[0015] This generator rotor lamination stamping composite mold features a detachable connection between the mold mechanism and the base plate. During actual production, when different sizes of rotor laminations need to be processed, the operator can precisely control the sliding components and guide columns of the connecting mechanism to work together via the controller. Specifically, the sliding components move the guide columns, which in turn cause the first and second guide blocks connected to the mold mechanism to move the lower and upper mold bases respectively, separating the limiting plate from the base plate groove. Finally, the mold mechanism is removed from the base plate, and then replaced with a mold mechanism matching the target rotor lamination size. Once the new mold mechanism is installed, it can accurately stamp rotor laminations of different sizes. This design effectively avoids the problem of equipment malfunction due to mismatch between the mold mechanism and the rotor lamination size, significantly improving the equipment's versatility and practicality, reducing production costs, and increasing 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] Please refer to Figures 1-4. A composite die for stamping generator rotor laminations includes a base plate 1, a support base 2, a die mechanism 3, and a connecting mechanism 9. The support base 2 is disposed at the bottom of the base plate 1, and there are several support bases 2. The die mechanism 3 is connected to the base plate 1 through the connecting mechanism 9. The die mechanism 3 includes a lower die base 4, a groove 5, an upper die base 6, a protrusion 7, and a mounting block 16. The groove 5 is formed on the lower die base 4, the protrusion 7 is disposed on the upper die base 6, and the mounting block 16 is fixedly connected to the top of the upper die base 6. The upper die base 6 matches the lower die base 4, and the groove 5 matches the protrusion 7. A through hole 8 is formed on the base plate 1, and the through hole 8 penetrates the base plate 1. The connecting mechanism 9 includes a sliding assembly 10, a guide post 11, a first guide block 12, a second guide block 13, and a limiting plate 14. The guide post 11 is connected to the base plate 1 through the sliding assembly 10. One end of the first guide block 12 is connected to the lower mold base 4 and is fitted onto the guide post 11. One end of the second guide block 13 is connected to the upper mold base 6 and is fitted onto the guide post 11. One end of the limiting plate 14 is connected to the lower mold base 4, and the other end of the limiting plate 14 extends into the base plate 1. The base plate 1 has a groove that matches the limiting plate 14. A controller 15 is provided on the front of the base plate 1, and the controller 15 is electrically connected to the sliding assembly 10.

[0023] Working principle: Place the equipment in the designated position and use several symmetrically arranged support seats 2 to stably support the equipment. Then, connect the equipment to the external mains power to complete the power-on operation. Referring to Figure 1, precisely align the output end of the external press with the mounting block 16 on the top of the upper die base 6 and secure it firmly using external bolts and other components. The specific fixing method will not be described in detail here. Subsequently, select a rotor lamination that matches the groove 5 on the lower die base 4 and place it smoothly into the groove 5. The rotor lamination fits into the groove 5, and the groove 5 can limit the position of the rotor lamination, ensuring the stable position of the rotor lamination during the stamping process. Once the position is fixed, the external press is started. The press drives the upper mold base 6 to descend, which in turn drives the protrusion 7 on the upper mold base 6 to descend synchronously. The protrusion 7 cooperates with the groove 5 to stamp the rotor lamination in the groove 5. The groove 5 has pre-drilled holes, and the protrusion 7 is equipped with punch blocks and other structures. Excess waste generated during the stamping process will be discharged from the groove 5 through the through hole 8 at the bottom of the base plate 1. After the stamping is completed, the operator uses an external cylindrical tool to insert it into the groove 5 through the through hole 8 at the bottom of the base plate 1. The cylinder passes through the through hole 8 and the punch hole on the groove 5 to push out the stamped rotor lamination, thus completing one stamping operation.

[0024] Changeover Operation: When stamping rotor laminations of different sizes requires changing the mold mechanism 3, first ensure the equipment is stopped and the upper mold base 6 is separated from the external press. Carefully inspect the interiors of the upper and lower mold bases to ensure no waste material remains. Then, operate the controller 15 to simultaneously activate the two sliding components 10. Each sliding component 10 includes a conventional structure such as a groove, slider, motor, and threaded rod. The motor drives the threaded rod to rotate, causing the slider to move within the groove, thus synchronizing the movement of the two sliding components 10 and translating the guide column 11. At this time, the first guide block 12 connected to the lower mold base 4 and the second guide block 13 connected to the upper mold base 6 will respectively drive the lower mold base 4 and the upper mold base 6 to move. When the lower mold base 4 moves... The limiting plate 14 connected to it will also move until the limiting plate 14 is completely separated from the groove opened on the base plate 1. Next, the operator will manually pull up the upper mold base 6 and the lower mold base 4 in sequence to disengage the second guide block 13 and the first guide block 12 from the guide post 11. This allows the upper mold base 6 and the lower mold base 4 to be removed from the equipment. The manufacturer will provide mold mechanisms 3 of various sizes when producing the equipment, and consumers can freely choose according to their actual needs. When changing the mold, simply follow the reverse order of the disassembly steps. The specific installation steps will not be elaborated here. It should be noted that the size of the groove 5 in the lower mold base 4 must not exceed the size of the through hole 8 in the base plate 1, otherwise the punch hole on the groove 5 will be blocked, affecting the discharge of waste material and the ejection of the punch.

[0025] The upper die holder 6 and lower die holder 4 in this paper are made of high-strength, high-hardness, and wear-resistant Cr12MoV die steel. This steel has good hardenability and wear resistance. Even though the lower die holder 4 is not in complete contact with the base plate 1 due to the through hole 8 on the base plate 1, it can still effectively reduce the risk of deformation and cracking when subjected to the pressure applied by the upper die holder 6, thereby ensuring the service life and stamping accuracy of the die. To obtain good comprehensive mechanical properties, the Cr12MoV steel used in the upper die holder 6 and lower die holder 4 needs to undergo quenching and tempering treatment, with the quenching temperature set at 102°C. The holding time is 2 hours at 0℃; the tempering temperature is 520℃ and the holding time is 3 hours. In addition, to further reduce the wear between the various parts of the mold and improve the smoothness of the equipment operation, a ceramic coating is applied to the surface of all parts that come into contact with each other, such as the guide post 11, the first guide block 12 and the second guide block 13. The main components of the ceramic coating are alumina and zirconium oxide, and the coating thickness is 50μm. The coating is applied using a plasma spraying process. This coating can not only reduce the friction coefficient between parts and reduce wear, but also improve the overall performance and service life of the mold.

[0026] The tolerances of the guide post 11, the first guide block 12, the second guide block 13, the limiting plate 14, and the groove on the base plate 1 are not specifically limited in the text and need to be flexibly determined based on various factors in actual application.

[0027] The stability of the aforementioned support base 2 is poor. To solve this problem, in this embodiment, several of the aforementioned support bases 2 are symmetrically arranged.

[0028] The bottom of the support base 2 has poor anti-slip effect. When the bottom of the support base 2 comes into contact with the smooth ground, it is easy to slip. In order to solve this problem, in this embodiment, the bottom of the support base 2 is provided with an anti-slip layer, and the anti-slip layer is fixedly connected to the bottom of the support base 2.

[0029] To improve the anti-slip effect, in this embodiment, the bottom of the anti-slip layer is provided with anti-slip texture, and the anti-slip texture has several strips.

[0030] To improve the connection effect, in this embodiment, the first guide block 12 is welded to the lower mold base 4, and the second guide block 13 is welded to the upper mold base 6.

[0031] The anti-slip effect of the outer walls of the first guide block 12 and the second guide block 13 is poor. When the workers lift the lower mold base 4 and the upper mold base 6 by holding the first guide block 12 and the second guide block 13, their hands are prone to slipping. In order to solve this problem, in this embodiment, the outer walls of the first guide block 12 and the second guide block 13 are provided with anti-slip layers.

[0032] The dimensions and shapes of all components in this structure are not specifically limited here and need to be produced according to the actual situation. The control method of this utility model is controlled by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in this field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and wiring layout will not be explained in detail here.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
