Description

Technical Field

[0001] The utility model relates to the technical field of iron core processing, in particular to a discharging mechanism of a high-speed blanking die for a motor iron core. Background Art

[0002] At present, the blanking speed of high-precision progressive dies on the market is only 250 - 500 SPM, which has a large gap from the 1000 SPM of ultra-high-speed and ultra-precision progressive dies. When the blanking die reaches the ultra-high-speed level, the length of the required discharging mechanism is relatively long, resulting in a relatively high floor area requirement for the discharging mechanism. When the space area is small, it cannot meet the layout area requirement of the discharging mechanism. Summary of the Invention

[0003] By providing a discharging mechanism of a high-speed blanking die for a motor iron core in an embodiment of the present application, with an included angle between the discharging section and the connecting section and an arc transition connection between them through a transition section, while adapting to the requirements of different production line layouts or downstream processes, the stagnation time of the iron core during discharging is reduced, and the iron core products will not accumulate.

[0004] To achieve the above object, the utility model provides the following technical solution: A discharging mechanism of a high-speed blanking die for a motor iron core, the discharging mechanism is connected to the end of the blanking die through a connecting plate. The discharging mechanism includes a discharging guide rail, a punching machine base for installing the discharging guide rail, and an iron core is arranged inside the discharging guide rail. The discharging guide rail includes a connecting section with a setting direction consistent with the discharging direction of the blanking die, a discharging section with a setting direction having an included angle with the connecting section, and a transition section that arc-transitionally connects the connecting section and the discharging section.

[0005] Compared with the prior art, the advantages of the utility model are as follows:

[0006] Due to the limitation of the factory building space, the discharging guide rail is designed in three sections, namely a connecting section, a discharging section, and a transition section. The discharging section has an included angle with the connecting section and the feeding and discharging sections are arc-transitionally connected through the transition section, effectively reducing the floor area of the discharging guide rail;

[0007] At the same time, when the iron core passes through the included angle between the discharging section and the connecting section, due to the arc setting of the transition section, the impact and friction force during the material direction conversion are reduced, avoiding problems such as material jamming and scratching caused by right-angle or acute-angle transitions. This smooth transition helps to protect the surface quality of the material and extend the service life of the equipment;

[0008] The consistency of the connecting section with the discharging direction of the blanking die ensures that the material after punching can directly and unobstructedly enter the discharging mechanism, reducing the collision and damage of the material during the conversion process, and improving the production efficiency and product quality.

[0009] As an improvement, the iron core is square, and the discharge guide rail is fixedly connected by surrounding the iron core with several steel round tubes. The discharge guide rail formed by surrounding the iron core with several steel round tubes forms an annular closed structure, enabling the iron core to flow continuously and stably within the closed loop.

[0010] As an improvement, the discharge mechanism further includes several guide plates dispersedly arranged along the direction of the discharge guide rail. The guide plates surround the steel round tubes and are fixedly connected to the steel round tubes. The guide plates are dispersedly arranged along the direction of the discharge guide rail, which can effectively disperse the force received by the steel round tubes to each guide plate, thereby enhancing the structural stability of the entire discharge mechanism. This design makes the discharge mechanism more stable when bearing the weight and impact force of the material, reducing the risk of deformation and displacement; the steel round tubes are fixedly connected through the guide plates, ensuring the relative position stability between the steel round tubes and avoiding loosening or dislocation caused by vibration or impact. This stable connection method helps to keep the discharge section unobstructed and improve the discharge efficiency.

[0011] As an improvement, the wall near the end of the discharge section is provided with a support rod and a mounting seat. One end of the support rod is connected to the wall through the mounting seat, and the other end of the support rod is fixedly connected to the adjacent guide plate. The support rod is directly connected to the wall and the guide plate, forming a stable support structure, effectively enhancing the load-bearing capacity and stability at the end of the discharge section. This design can prevent the deformation or displacement of the guide plate caused by the weight or impact force of the material, ensuring the stable operation of the entire discharge system.

[0012] As an improvement, the discharge mechanism further includes a pressing component arranged at the end of the discharge section. Both sides of the pressing component are fixed to the end of the discharge section through the guide plates. The pressing component arranged at the end of the discharge section can apply a certain pressure to the iron core, enabling it to maintain a stable posture and position during the discharge process, reducing the scattering or deviation of the material caused by vibration or impact. This is particularly important for the process that requires precise control of the shape and position of the iron core.

[0013] As an improvement, the length of the steel round tube arranged away from the pressing component at the end of the discharge section is longer than the length of the steel round tube arranged near the pressing component. The pressing component presses the iron core against the steel round tube arranged away from the pressing component. Since the length of the steel round tube arranged away from the pressing component at the end of the discharge section is longer than the length of the steel round tube arranged near the pressing component, it enables the end of the discharge section to provide a longer transportation path for the iron core, and at the same time makes the end of the discharge section near the pressing component exposed, facilitating the subsequent taking of products.

[0014] As an improvement, the pressing assembly includes a first pressing plate disposed away from the discharge section, a second pressing plate disposed inside the discharge section, connecting bolts connecting the first pressing plate and the second pressing plate, and springs sleeved on the outer peripheral wall of the connecting bolts. The upper ends of the two guide plates are connected to both sides of the first pressing plate. One end of the spring abuts against the first pressing plate, and the other end of the spring abuts against the connecting bolts, so that the second pressing plate abuts against one end of the iron core. The pressing structure includes a first pressing plate away from the discharge section and a second pressing plate disposed inside the discharge section. Through the dual action of the connecting bolts and the springs, the stable pressing of the material is ensured. By pressing the iron core, the accumulation and blockage of the iron core in the discharge section can be reduced, ensuring that the material can smoothly pass through the discharge mechanism and improving production efficiency. The springs sleeved on the outer peripheral wall of the connecting bolts not only play a role in connection and fixation, but also provide buffering during the pressing process, reducing the impact on the equipment itself and extending the service life of the equipment.

[0015] As an improvement, the arc radius from the center of the iron core disposed in the transition section to the center of the arc of the transition section is 7 to 10 times the length of the iron core. Under the condition of meeting the site and production requirements, the ratio of the distance from the center of the iron core to the center of the transition section to the length of the iron core is 7 to 10, so that the iron core can be discharged smoothly in the transition section and the wear of the iron core can be prevented at the same time.

[0016] As an improvement, the rear end of the connecting plate is fixedly connected to the discharge guide rail. Positioning keys are provided on both sides of the connecting plate. The blanking die includes the lower table surface of the punching press. A stepped groove is provided on one side of the lower table surface of the punching press close to the discharge mechanism. The connecting plate is positioned and connected to the upper end of the stepped groove through the positioning keys. The combined use of the positioning keys and the stepped groove realizes the precise positioning of the connecting plate on the lower table surface of the punching press. This design ensures that the position of the connecting plate is accurate during the installation process, thereby improving the accuracy and reliability of the entire discharge mechanism.

[0023] As Figure 1 As shown, a discharging mechanism of a high-speed blanking die for a motor iron core, the discharging mechanism 1 is connected to the end of the blanking die 2 through a connecting plate 3. The discharging mechanism 1 includes a discharging guide rail 1.1 and a punch base 1.2 for installing the discharging guide rail 1.1.

[0024] The central distance from the center of the iron core 7 arranged in the transition section to the center of the arc of the transition section 1.1.3 is 7 to 10 times the length of the iron core 7, and the arc radius from the center of the iron core 7 arranged in the transition section to the center of the arc of the transition section 1.1.3 is the turning radius of the iron core in the transition section.

[0025] A support rod 4 and a mounting seat 5 are arranged on the wall near the end of the discharging section 1.1.2. One end of the support rod 4 is connected to the wall through the mounting seat 5, and the other end of the support rod 4 is fixedly connected to the adjacent guide plate 1.3.

[0026] The rear end of the connecting plate 3 is fixedly connected to the discharging guide rail 1.1. Positioning keys 6 are arranged on both sides of the connecting plate 3. The blanking die 2 includes a lower bed surface 2.1 of the punching machine. A stepped groove 2.1.1 is arranged on one side of the lower bed surface 2.1 of the punching machine close to the discharging mechanism 1. The connecting plate 3 is positioned and connected to the upper end of the stepped groove 2.1.1 through the positioning keys 6.

[0027] The discharging mechanism 1 further includes a pressing assembly 1.4 arranged at the end of the discharging section 1.1.2. Both sides of the pressing assembly 1.4 are fixedly arranged at the end of the discharging section 1.1.2 through guide plates 1.3.

[0028] The discharging mechanism 1 further includes a plurality of guide plates 1.3 dispersedly arranged along the direction of the discharging guide rail 1.1. The guide plates 1.3 surround the steel round tube 1.1.4 and are fixedly connected to the steel round tube 1.1.4.

[0029] The length of the steel round tube 1.1.4 arranged at the end of the discharging section 1.1.2 and far from the pressing assembly 1.4 is longer than the length of the steel round tube 1.1.4 arranged close to the pressing assembly 1.4.

[0030] As Figures 2 to 3 shown, the pressing assembly 1.4 includes a first pressing plate 1.4.1 arranged far from the discharging section 1.1.2, a second pressing plate 1.4.2 arranged inside the discharging section 1.1.2, a connecting bolt 1.4.3 connecting the first pressing plate 1.4.1 and the second pressing plate 1.4.2, and a spring 1.4.4 sleeved on the outer peripheral wall of the connecting bolt 1.4.3. The upper ends of the two guide plates 1.3 are connected to both sides of the first pressing plate 1.4.1. One end of the spring 1.4.4 abuts against the first pressing plate 1.4.1, and the other end of the spring 1.4.4 abuts against the connecting bolt 1.4.3 so that the second pressing plate 1.4.2 abuts against one end of the iron core 7.

[0031] As Figure 3 shown, the iron core 7 is square. The discharging guide rail 1.1 is fixedly connected by surrounding the iron core 7 with a plurality of steel round tubes 1.1.4. Preferably, the number of the steel round tubes 1.1.4 is 8, and 2 steel round tubes 1.1.4 are respectively arranged at the upper end, the lower end and both sides of the iron core.

[0032] The iron core 7 after blanking enters the connecting section 1.1.1 of the discharge guide rail 1.1 from the discharge port of the blanking die 2. The steel round tube 1.1.4 limits the iron core 7. After the iron core 7 enters the transition section 1.1.3 from the connecting section 1.1.1, it enters the discharge section 1.1.2 and reaches the end of the discharge section 1.1.2, so that the second pressing plate 1.4.2 abuts against one end of the iron core 7, and the spring 1.4.4 is compressed, so that one end of the spring 1.4.4 abuts against the first pressing plate 1.4.1, and the other end of the spring 1.4.4 abuts against the connecting bolt 1.4.3, so that the second pressing plate 1.4.2 abuts against one end of the iron core 7 more tightly, preventing the iron core 7 from flying out due to high-speed blanking during discharging, causing damage to the iron core 7. At the same time, the iron core 7 can be sorted neatly and taken out from the exposed part at the end of the discharge section 1.1.2.

[0033] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the technical solution of the present utility model, or the concept and technical solution of the present utility model are directly applied to other occasions without improvement, they are all within the protection scope of the present utility model.
