Description

Technical Field

[0001] This utility model relates to the field of amorphous motor stator stamping technology, specifically an amorphous motor stator stamping machine. Background Technology

[0002] An amorphous motor stator refers to a stator core made of amorphous alloy material. It is the stationary part of a motor or generator. During the production process of an amorphous motor stator, the amorphous alloy material is stamped using a stamping machine. In existing technology: [Authorization Publication No. CN 221715411] U's patent discloses a motor stator stamping equipment, including a base, an electric turntable at the top center of the base, and a connecting mechanism mounted on the top of the mounting frame via an electric telescopic rod. A stamping head is detachably mounted on the connecting mechanism, and the stamping head is adapted to the stamping base. The connecting mechanism includes a first mounting base and a second mounting base connected below the first mounting base. Insert plates are slidably connected to the left and right side walls of the second mounting base. A toothed plate is provided on the opposite side of the two sets of insert plates, and a gear is meshed between the two sets of toothed plates. This utility model is convenient and quick to assemble and disassemble, facilitating the stamping of motor stators of different models. It can also cool down the stamped motor stator to avoid burns to workers, reduce danger, facilitate material handling, and improve stamping efficiency. However, after the device stamps amorphous motor stator raw materials, the stamping residue on the outside of the amorphous motor stator raw materials, the stamped amorphous motor stator raw materials, and the stamping residue inside the amorphous motor stator all remain inside the stamping die, which is not conducive to the unloading operation of the workers. Therefore, we propose an amorphous motor stator stamping machine. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide an amorphous motor stator stamping machine. This device uses an elastic reset element and the different height differences between the rods to make the external stamping residue of the amorphous motor stator raw material, the stamped product of the amorphous motor stator raw material, and the internal stamping residue of the amorphous motor stator vertically staggered and separated from the stamping die after the stamping is completed. This facilitates the workers to classify and unload the materials, and can effectively solve the problems in the background technology.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an amorphous motor stator stamping machine, comprising a stamping shell, wherein the bottom wall of the stamping shell is provided with transversely symmetrically distributed dovetail grooves, and two stamping dies are slidably connected between the dovetail grooves, wherein each stamping die is provided with a mold cavity on its upper side, and a stamping head is provided on the upper side of the stamping shell through the telescopic end of an electro-hydraulic push rod, and further comprising a material ejection mechanism. The ejection mechanism includes ejection rod 1, ejection rod 2, ejection rod 3, an inner cavity, and elastic components. The inner cavity is located inside the stamping die. Ejection rod 1 is slidably connected to a circular hole 1 in the middle of the stamping die. Circular holes 2 and 3 are symmetrically distributed laterally in the middle of the stamping die. Ejection rod 2 is slidably connected to the inside of circular hole 2, and ejection rod 3 is slidably connected to the inside of circular hole 3. Elastic components are provided inside each inner cavity. Ejection rod 1, ejection rod 2, and ejection rod 3 are all fixedly connected to adjacent elastic components. This device, through an elastic reset element, utilizes the different height differences between the rods to ensure that after the amorphous motor stator raw material is stamped, the external stamping residue of the amorphous motor stator raw material, the stamped product of the amorphous motor stator raw material, and the internal stamping residue of the amorphous motor stator are vertically staggered and vertically separated from the stamping die, facilitating the sorting and unloading operations by the workers.

[0005] Furthermore, it also includes a microcontroller, which is located outside the stamping shell. The input terminal of the microcontroller is electrically connected to an external power supply, and the output terminal of the microcontroller is electrically connected to the input terminal of the electro-hydraulic actuator, which facilitates the control of the electrical components inside the device.

[0006] Furthermore, a laser sensor is provided on the upper side of the stamping head. The laser sensor is bidirectionally electrically connected to the microcontroller to measure and upload the downward movement distance of the stamping head in the amorphous motor stator stamping machine.

[0007] Furthermore, the elastic component includes a rectangular frame, circular plates, telescopic columns, and springs. The rectangular frames are located inside the inner cavity. The lower ends of ejector rod one, ejector rod two, and ejector rod three are fixedly connected to adjacent rectangular frames. The lower side of the rectangular frame and the bottom wall of the inner cavity are provided with evenly distributed circular plates. Telescopic columns and springs are provided between two vertically adjacent circular plates. The springs are movably sleeved with the outer ends of the adjacent telescopic columns. The front side of the stamping die is provided with a sealing plate by bolts, so that ejector rod one, ejector rod two, and ejector rod three in the amorphous motor stator stamping machine can automatically move upward and reset after being pressed.

[0008] Furthermore, the height of the ejector rod one is lower than the height of the ejector rod two, and the height of the ejector rod two is lower than the height of the ejector rod three, so that the external stamping residue of the amorphous motor stator raw material, the stamped product of the amorphous motor stator raw material and the internal stamping residue of the amorphous motor stator in the stamping part of the device are vertically misaligned.

[0009] Furthermore, an electro-hydraulic push rod 2 is provided at the lower end of the interior of the stamping shell. The input end of the electro-hydraulic push rod 2 is electrically connected to the output end of the microcontroller. The telescopic end of the electro-hydraulic push rod 2 is fixedly connected to the rear side of the stamping die through a synchronizing rod. A transversely symmetrical connecting rod is provided between the two stamping dies to adjust the position of the stamping dies in the amorphous motor stator stamping machine, so that the two sets of stamping dies can be used in conjunction.

[0010] Furthermore, the bottom wall of the stamping shell is equipped with a second laser sensor, which is bidirectionally electrically connected to the microcontroller to measure and upload the longitudinal movement distance of the stamping die inside the amorphous motor stator stamping machine.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This amorphous motor stator stamping machine has the following advantages: When using an amorphous motor stator stamping machine, the elastic component allows the internal ejector bar to automatically reset after being pressed. At the same time, by utilizing the different height differences between the ejector bars, after the amorphous motor stator raw material is stamped, the external stamping residue of the amorphous motor stator raw material, the stamped product of the amorphous motor stator raw material, and the internal stamping residue of the amorphous motor stator are vertically staggered and separated from the stamping die, thus facilitating the sorting and unloading operations of the workers.

[0014] 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.

[0015] Please see Figure 1-3This embodiment provides a technical solution: an amorphous motor stator stamping machine, including a stamping shell 1, with transversely symmetrical dovetail grooves 3 on the bottom wall of the stamping shell 1, two stamping dies 4 slidably connected between the dovetail grooves 3, and a mold cavity 5 on the upper side of each stamping die 4. A stamping head 7 is provided on the upper side of the stamping shell 1 through the telescopic end of an electro-hydraulic push rod 6. The machine also includes a microcontroller 2, located outside the stamping shell 1. The input end of the microcontroller 2 is electrically connected to an external power supply, and the output end of the microcontroller 2 is electrically connected to the input end of the electro-hydraulic push rod 6. A laser sensor 8 is provided on the upper side of the stamping head 7, and the laser sensor 8 is bidirectionally electrically connected to the microcontroller 2. The positional and dimensional relationships between the internal components are recorded in the microcontroller 2, and the amorphous motor stator raw material is vertically placed from top to bottom into the mold cavity 5 of the stamping die 4. Inside, when the device performs stamping operations on the amorphous motor stator material, the microcontroller 2 activates the electro-hydraulic push rod 6, causing its telescopic end to drive the stamping head 7 to move vertically downward, thereby performing stamping operations on the amorphous motor stator material in the mold cavity 5. During this process, the microcontroller 2 activates the laser sensor 8, which emits a light signal to illuminate the top wall of the stamping shell 1 and reflects it back to the initial position. Based on the propagation time and speed of the light signal, the downward movement distance of the stamping head 7 is obtained and transmitted to the microcontroller 2 as an electrical signal. The microcontroller 2 adjusts the vertical movement distance of the stamping head 7 driven by the telescopic end of the electro-hydraulic push rod 6 according to the measured distance and the positional and dimensional relationships between the components inside the device, so that the stamping head 7 can accurately perform stamping operations on the amorphous motor stator material below. The device also includes a material ejection mechanism 9. The ejection mechanism 9 includes ejection rod 1 91, ejection rod 2 92, ejection rod 3 93, an inner cavity 94, and elastic components 95. The inner cavities 94 are respectively opened inside the stamping die 4. Ejection rod 1 91 is slidably connected to each of the circular holes 1 opened in the middle of the stamping die 4. Circular holes 2 and 3 are symmetrically distributed laterally in the middle of the stamping die 4. Ejection rod 2 92 is slidably connected to each of the circular holes 2 and 3. Ejection rod 3 93 is slidably connected to each of the circular holes 3. Elastic components 95 are provided inside each of the inner cavities 94. Ejection rod 1 91, ejection rod 2 92, and ejection rod 3 93 are all fixedly connected to adjacent elastic components 95. Each elastic component 95 includes a rectangular frame 951, a circular plate 952, a telescopic column 953, and a spring 954. The rectangular frame 951 is respectively positioned... Inside the inner cavity 94, the lower ends of ejector rod 1 91, ejector rod 2 92, and ejector rod 3 93 are all fixedly connected to the adjacent rectangular frame 951. The lower side of the rectangular frame 951 and the bottom wall of the inner cavity 94 are provided with evenly distributed circular pieces 952. Between two vertically adjacent circular pieces 952, there are telescopic columns 953 and springs 954. The springs 954 are movably sleeved with the outer ends of the adjacent telescopic columns 953. The front side of the stamping die 4 is provided with sealing plates 14 by bolts. The height of ejector rod 1 91 is lower than that of ejector rod 2 92, and the height of ejector rod 2 92 is lower than that of ejector rod 3 93. The lower end of the stamping shell 1 is provided with an electro-hydraulic pusher 2 11. The input end of electro-hydraulic pusher 2 11 is electrically connected to the output end of the microcontroller 2. The telescopic end of rod 2 11 is fixedly connected to the rear side of the stamping die 4 via synchronous rod 12. A transversely symmetrically distributed connecting rod 10 is provided between the two stamping dies 4. A laser sensor 2 13 is provided on the bottom wall of the stamping shell 1. The laser sensor 2 13 is bidirectionally electrically connected to the microcontroller 2. During the stamping process of the amorphous motor stator material, the lower side of the amorphous motor stator material contacts the upper side of the ejector rod 3 93. As the stamping head 7 stamps the amorphous motor stator material, the amorphous motor stator material moves downward along the die cavity 5. The ejector rod 3 93 is subjected to the downward pressure of the amorphous motor stator material, thereby driving the corresponding rectangular frame 951 downward along the corresponding circular hole 3. The telescopic end of the telescopic column 953 and the spring 954 retract. Simultaneously, the ejector rod 3 93 indirectly drives the corresponding rectangular frame 951 through the rectangular frame 951. The ejector rods 91 and 92 move down synchronously and slide into the corresponding circular holes 1 and 2, respectively, ensuring that the ejector rods are all inside the corresponding circular holes. This allows for positional avoidance of the stamping of the amorphous motor stator material. After the amorphous motor stator material is stamped, the microcontroller 2 controls the telescopic end of the electro-hydraulic push rod 6 using the same principle, causing it to drive the stamping head 7 to move upward and reset. During this process, the rectangular frame 951 automatically moves upward due to the compression and reset force of the spring 954. As the rectangular frame 951 moves upward and resets, it drives the corresponding ejector rods 91, 92, and 93 to move synchronously. The ejector rod 91 lifts up the middle residue of the stamped amorphous motor stator material, and the ejector rod 92 pushes up the stamped product of the amorphous motor stator material.The external residue from the stamping of the amorphous motor stator material is pushed upward by the ejector rod 93. Due to the different heights of the ejector rods 91, 92, and 93, the middle residue from the stamping of the amorphous motor stator material, the stamped product from the amorphous motor stator material, and the external residue from the stamping of the amorphous motor stator material are vertically staggered and separated from the mold cavity 5. This facilitates the sorting and unloading of the three materials by the workers. Before the amorphous motor stator stamping unloads, the microcontroller 2 activates the electro-hydraulic push rod 11, causing its extension end to be driven by the synchronizing rod 12. The side stamping die 4 moves backward along the dovetail groove 3. The rear stamping die 4 drives the front stamping die 4 to move backward synchronously along the dovetail groove 3 via the connecting rod 10. At the same time, the microcontroller 2 activates the laser sensor 13. The laser sensor 13 detects the longitudinal movement distance of the front stamping die 4 using the same principle and transmits the detection result to the microcontroller 2 as an electrical signal. Based on the measured result and the positional dimensions between the various components inside the device, the microcontroller 2 precisely controls the movement distance of the telescopic end of the electro-hydraulic push rod 11, so that the stamping die in the middle of the device moves backward each time. All four die 4 move longitudinally to directly below the stamping head 7. During the operation of the device, while one stamping die 4 is performing stamping operations on the amorphous motor stator material, the other stamping die 4 is simultaneously performing the blanking and filling operations on the amorphous motor stator material. The two stamping dies 4 are used alternately to improve the stamping efficiency of the stamping machine on the amorphous motor stator as a whole. After the device has been used for a period of time, the sealing plate 14 is removed from the stamping die 4 by removing the bolts. Then, the circular piece 952 and the telescopic column 953 in the inner cavity 94 are processed through the exposed space of the stamping die 4. The entire spring 954 is replaced (the circular pieces 952 are all fixedly connected to the bottom wall of the corresponding rectangular frame 951 or inner cavity 94 by bolts 2), thus avoiding aging of the spring 954 due to long-term use. This device, through an elastic reset element, utilizes the different height differences between the rods to ensure that after the amorphous motor stator material is stamped, the external stamping residue of the amorphous motor stator material, the stamped product of the amorphous motor stator material, and the internal stamping residue of the amorphous motor stator are vertically staggered and simultaneously separated from the stamping die 4, facilitating the sorting and unloading operations by the workers.

[0016] The working principle of the amorphous motor stator stamping machine provided by this utility model is as follows: The positional and dimensional relationships between the various components inside the device are entered into the microcontroller 2. The amorphous motor stator material is placed vertically from top to bottom into the mold cavity 5 of the stamping die 4. When the device performs stamping operations on the amorphous motor stator material, the microcontroller 2 activates the electro-hydraulic push rod 6, causing its telescopic end to drive the stamping head 7 to move vertically downward, thereby performing stamping operations on the amorphous motor stator material in the mold cavity 5. During this process, the microcontroller 2 activates the laser sensor 8, which emits a light signal that irradiates the top wall of the stamping shell 1 and reflects back to the initial position. The downward movement distance of the stamping head 7 is obtained based on the propagation time and speed of the light signal, and transmitted to the microcontroller 2 as an electrical signal. Based on the measured distance and the positional and dimensional relationships between the internal components, the chipper 2 adjusts the vertical movement distance of the stamping head 7 driven by the telescopic end of the electro-hydraulic push rod 6. This allows the stamping head 7 to accurately stamp the amorphous motor stator material below. During the stamping process, the lower side of the amorphous motor stator material contacts the upper side of the ejector rod 93. As the stamping head 7 presses against the amorphous motor stator material, the material moves downward along the mold cavity 5. The ejector rod 93, under the downward pressure of the material, moves downward along the corresponding circular hole 951, causing the corresponding rectangular frame 951 to move downward. The telescopic end of the telescopic column 953 and the spring 954 retract, and simultaneously, the ejector rod 93 indirectly drives the corresponding ejector through the rectangular frame 951. Rod 1 91 and ejector rod 2 92 move down synchronously and slide into the corresponding circular holes 1 and 2, respectively, so that the ejector rods slide into the corresponding circular holes, thereby avoiding the stamping of the amorphous motor stator material. After the amorphous motor stator material is stamped, the microcontroller 2 controls the telescopic end of the electro-hydraulic push rod 6 through the same principle to drive the stamping head 7 to move up and reset. During this process, the rectangular frame 951 moves up automatically due to the compression and reset force of the spring 954. During the upward reset process of the rectangular frame 951, it drives the corresponding ejector rods 1 91, 2 92 and 3 93 to move synchronously. The ejector rod 1 91 lifts up the middle residue of the stamped amorphous motor stator material, and the ejector rod 2 92 pushes up the stamped product of the amorphous motor stator material. The ejector rod 93 pushes up the external residue of the amorphous motor stator material stamping. Due to the different heights of ejector rods 91, 92, and 93, the middle residue of the amorphous motor stator material stamping, the stamped product of the amorphous motor stator material, and the external residue of the amorphous motor stator material stamping are vertically staggered and separated from the mold cavity 5. This facilitates the sorting and unloading of the three materials by the workers. Before the amorphous motor stator stamping unloading, the microcontroller 2 activates the electro-hydraulic push rod 11, causing its extension end to drive the rear stamping die 4 to move backward along the dovetail groove 3 via the synchronizing rod 12. The rear stamping die 4 drives the front stamping die 4 to move backward synchronously along the dovetail groove 3 via the connecting rod 10.The microcontroller 2 activates the laser sensor 13. The laser sensor 13 detects the longitudinal movement distance of the front stamping die 4 using the same principle and transmits the detection result to the microcontroller 2 as an electrical signal. Based on the measured result and the positional dimensions of the internal components, the microcontroller 2 precisely controls the movement distance of the telescopic end of the electro-hydraulic push rod 11, ensuring that the stamping die 4 in the middle of the device moves longitudinally to directly below the stamping head 7 each time. During operation, while one stamping die 4 is stamping amorphous motor stator material, the other stamping die 4 is simultaneously stamping amorphous materials. The stamping and blanking of the motor stator raw material and the filling of the amorphous motor stator raw material are carried out using two stamping dies 4 alternately, thereby improving the stamping efficiency of the stamping machine on the entire amorphous motor stator. After the device has been used for a period of time, the sealing plate 14 is removed from the stamping die 4 by removing the bolts. Then, the circular piece 952, the telescopic column 953, and the spring 954 inside the inner cavity 94 are replaced as a whole through the exposed space of the stamping die 4 (the circular piece 952 is fixedly connected to the corresponding rectangular frame 951 or the bottom wall of the inner cavity 94 by bolts 2), thereby avoiding aging of the spring 954 due to long-term use.
