Description

Technical Field

[0001] This utility model relates to the field of aluminum disc production technology, specifically a continuous mold for aluminum disc production. Background Technology

[0002] Aluminum discs are circular aluminum material products commonly used to manufacture various parts or products. Aluminum discs are lightweight, corrosion-resistant, and easy to process, making them widely used in aerospace, automotive, electronics, and construction industries. During production, aluminum discs require stamping and cutting using molds. Existing technology includes a patent (CN 220805140 U) that discloses a stamping mold for aluminum parts processing, comprising a mold frame, a placement frame fixedly mounted on the side wall of the mold frame, a lower template mounted on the placement frame, multiple punching holes on the top of the lower template, an upper hydraulic rod mounted on the inner top wall of the mold frame, and an upper template adapted to the lower template at the telescopic end of the upper hydraulic rod. A collection component located at the bottom of the lower template is used to quickly collect the stamped aluminum discs for continuous stamping and to avoid scratching the surface of the aluminum discs. This invention, by setting up a collection component, allows for faster stamping... The collecting component extends into the punching hole on the lower template, and the punched aluminum sheet falls onto the collecting component. Then, the collecting component retracts to await the next round of punching, realizing continuous punching, which speeds up the processing speed, supports the disc throughout the process, avoids scratching the disc surface, ensures the forming quality, and facilitates the packaging of the disc. However, when this device punches aluminum plates, after each aluminum disc is punched, the aluminum plate needs to be automatically fed through a transmission belt. The addition of the transmission belt increases the overall cost of the device. Therefore, we propose a continuous die for aluminum disc production. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a continuous die for the production of aluminum discs. After the aluminum discs are punched, the upper die moves up and resets. Through the cooperation of the components, the aluminum plate can be automatically punched and transported by the continuous die by the ratchet and pawl and the contact friction. The aluminum plate can be self-fed without the need for a conveying device, which reduces the production cost of the continuous die and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a continuous mold for producing aluminum discs, including a lower mold, an upper mold installed above the lower mold, uniformly distributed stamping grooves on the upper side of the lower mold, uniformly distributed stamping seats on the top wall of the upper mold, and a self-feeding mechanism.

[0005] The self-feeding mechanism includes a rectangular cavity, a rotating shaft, a rubber roller, a transmission assembly, and an auxiliary seat. The rectangular cavity is located at the left end of the lower mold. The rubber roller is rotatably connected to the inside of the rectangular cavity via the rotating shaft. A transmission assembly is provided between the lower mold, the upper mold, and the rotating shaft. An auxiliary seat is located on the upper left side of the lower mold. The auxiliary seat is installed in conjunction with the rubber roller. After the aluminum disc is punched, the upper mold moves upward and resets. Through the cooperation of the components, the ratchet and pawl engagement and contact friction can automatically perform continuous die punching and conveying of the aluminum disc. The self-feeding of the aluminum disc can be achieved without the need for conveying equipment, reducing the production cost of continuous dies.

[0006] Furthermore, the lower end of the lower mold is provided with a chute, which is installed in conjunction with the stamping groove to guide the stamped aluminum discs away from the device.

[0007] Furthermore, the transmission assembly includes a ratchet, an L-shaped groove, a pawl, a telescopic post, a spring, and a clearance groove. The ratchet is located at the front end of the rotating shaft. The pawl is slidably connected in the L-shaped groove at the bottom of the upper mold. The telescopic post and the spring are located between the L-shaped groove and the pawl. The spring is movably sleeved with the outer end of the telescopic post. A clearance groove is provided on the upper side of the lower mold and is connected to the rectangular cavity. This allows the aluminum plate to be automatically stamped and conveyed when the upper mold in the continuous mold for aluminum disc production moves upward.

[0008] Furthermore, the top wall of the upper mold is provided with a rectangular pressure frame through evenly distributed telescopic columns and springs. The springs are all movably connected to the outer ends of the adjacent telescopic columns. The stamping seats are all located inside the rectangular pressure frame. The lower side of the rectangular pressure frame is provided with rubber strips to limit the movement of the aluminum plate during the stamping process of the aluminum disc.

[0009] Furthermore, a synchronization seat is provided on the front side of the rectangular pressure frame, and an electro-hydraulic push rod is provided in the clearance groove two opened on the upper side of the lower mold. The input end of the electro-hydraulic push rod is electrically connected to the output end of an external microcontroller. The telescopic end of the electro-hydraulic push rod is provided with a top seat, which is installed in conjunction with the synchronization seat. This allows the rectangular pressure frame to be squeezed and separated from the aluminum plate first when the upper mold in the continuous mold for aluminum disc production moves upward, thus avoiding interference with the subsequent automatic feeding of the aluminum plate by the rubber roller.

[0010] Furthermore, the lower side of the upper mold is provided with evenly distributed guide pillars, and the upper side of the lower mold is provided with evenly distributed guide grooves, which guide the upper and lower molds of the continuous mold for aluminum disc production to move vertically closer together.

[0011] Furthermore, the lower mold has limiting grooves at both the front and rear ends of its upper side to limit the longitudinal and vertical offset movement of the aluminum plate within the continuous mold for aluminum disc production.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This continuous die for producing aluminum discs has the following advantages:

[0013] The continuous die used in aluminum disc production automatically feeds the aluminum discs during the upward movement and resetting process after the aluminum discs are punched. This is achieved through the cooperation of the rotating shaft, rubber roller, transmission components, auxiliary seat, and limiting groove, utilizing ratchet and pawl engagement and contact friction. This eliminates the need for conveying equipment, thus reducing the production cost of continuous dies. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Please see Figure 1-5This embodiment provides a technical solution: a continuous mold for producing aluminum discs, including a lower mold 1, an upper mold 2 installed above the lower mold 1, a uniformly distributed stamping groove 4 on the upper side of the lower mold 1, a uniformly distributed stamping seat 3 on the top wall of the upper mold 2, and a material conveying inclined plate 5 at the lower end of the interior of the lower mold 1. The material conveying inclined plate 5 is installed in conjunction with the stamping groove 4. When the device is used to stamp the aluminum discs, the telescopic end of the external hydraulic rod is first fixed to the upper mold 2. The aluminum discs in the stamping groove 4 fall downwards onto the inclined surface of the material conveying inclined plate 5, and the aluminum discs are automatically discharged along the inclined surface of the material conveying inclined plate 5. The device also includes a self-feeding mechanism 6.

[0022] The self-feeding mechanism 6 includes a rectangular cavity 61, a rotating shaft 62, a rubber roller 63, a transmission assembly 64, and an auxiliary seat 65. The rectangular cavity 61 is located at the left end of the lower mold 1. The rubber roller 63 is rotatably connected to the interior of the rectangular cavity 61 via the rotating shaft 62. The transmission assembly 64 is located between the lower mold 1, the upper mold 2, and the rotating shaft 62. An auxiliary seat 65 is located on the upper left side of the lower mold 1. The auxiliary seat 65 is installed in conjunction with the rubber roller 63. The transmission assembly 64 includes a ratchet 641, an L-shaped groove 642, a pawl 643, a telescopic column 644, a spring 645, and a clearance groove 646. The ratchet 641 is located at the front end of the rotating shaft 62. The pawl 643 is slidably connected to the L-shaped groove 642 at the bottom of the upper mold 2. The L-shaped groove 642 and the pawl 643 are connected in a sliding manner. Between the three parts, there is a telescopic column 644 and a spring 645. The spring 645 is movably sleeved with the outer end of the telescopic column 644. The upper side of the lower mold 1 has a relief groove 646, which is connected to the rectangular cavity 61. The top wall of the upper mold 2 is provided with a rectangular pressure frame 9 through evenly distributed telescopic columns 7 and springs 8. The springs 8 are all movably sleeved with the outer ends of the adjacent telescopic columns 7. The stamping seats 3 are all located inside the rectangular pressure frame 9. The lower side of the rectangular pressure frame 9 is provided with a rubber strip 10. The front side of the rectangular pressure frame 9 is provided with a synchronization seat 13. The relief groove 2 on the upper side of the lower mold 1 is provided with an electro-hydraulic push rod 11. The input end of the electro-hydraulic push rod 11 is electrically connected to the output end of an external microcontroller. The telescopic end of the electro-hydraulic push rod 11 is provided with a top seat 12. The upper mold 2 is installed in conjunction with the synchronous seat 13. The lower mold 2 has evenly distributed guide posts 14 on its lower side, and evenly distributed guide grooves 15 on its upper side. Limiting grooves 16 are provided at both the front and rear ends of the upper side of the lower mold 1. The initial end of the aluminum plate passes from left to right through the conveying gap formed by the lower side of the auxiliary seat 65 and the upper outer side of the rubber roller 63 (the auxiliary seat 65 ensures that the lower side of the aluminum plate in this area is pressed against the upper outer surface of the rubber roller 63, preventing subsequent pressing and conveying of the aluminum plate by the rubber roller 63). Simultaneously, the front and rear ends of the aluminum plate are located in the corresponding limiting grooves 16. The limiting grooves 16 limit the longitudinal and vertical movement of the aluminum plate. During aluminum disc stamping, the upper mold 2 moves vertically downwards via the extension and retraction of the external hydraulic rod. During the downward movement of die 2, its guide column 14 engages with the vertically corresponding guide groove 15, thereby ensuring vertical alignment between the upper die 2 and the lower die 1. When the upper die 2 moves downward to a certain extent, the lower side of the rectangular pressure frame 9 contacts the upper side of the aluminum plate at the stamping part of the lower die 1. As the upper die 2 continues to move downward, the rectangular pressure frame 9 is compressed, and the telescopic end of the telescopic column 7 and the spring 8 retract. The rectangular pressure frame 9 then compresses and limits the aluminum plate at the stamping part (a rubber strip 10 is provided on the lower side of the rectangular pressure frame 9, which increases the contact resistance between the lower side of the rectangular pressure frame 9 and the upper side of the aluminum plate, further improving the movement limiting effect of the rectangular pressure frame 9 on the aluminum plate), preventing positional movement during subsequent stamping. At this time, as the upper die 2 continues to move downward...The lower end of the pawl 643 passes through the clearance groove 646 and presses against the left end of the ratchet 641 (the pawl 643 is composed of a strip plate and vertically evenly distributed pawls). At this time, because the rectangular pressure frame 9 limits the movement of the aluminum plate, the contact friction between the aluminum plate and the outer side of the rubber roller 63 prevents the rotating shaft 62 from driving the ratchet 641 to rotate. Therefore, after the pawl 643 is pressed by the ratchet 641, the pawl 643 slides to the left along the L-shaped groove 642 to move and avoid the ratchet 64. The telescopic end of the telescopic column 644 and the spring 645 continue to stretch (the spring 645 initially...). (In the stretched state), as the upper mold 2 continues to move downward, the upper mold 2 drives its own stamping seat 3 to make stamping contact with the aluminum plate above the stamping groove 4. The lower end of the stamping seat 3 penetrates into the vertically corresponding stamping groove 4, thereby realizing the stamping and cutting operation of the aluminum disc above the stamping groove 4. After the aluminum disc is stamped, the lower side of the synchronous seat 13 contacts the upper side of the top seat 12. As the extension end of the external hydraulic rod drives the upper mold 2 to move upward and reset, the external microcontroller starts the electro-hydraulic push rod 11, causing its extension end to drive the top seat 12 to move upward slightly. The top seat 12 makes contact with the synchronous seat 13 by pressing, thereby making the synchronous seat 12 move upward. Step 13 moves the rectangular pressure frame 9 upward a certain distance, releasing the movement limit of the rectangular pressure frame 9 on the aluminum plate. Subsequently, as the upper mold 2 moves upward, the pawl 643 engages with the ratchet 641 under the tension and reset force of the spring 645, causing the ratchet 641 to drive the rubber roller 63 to rotate forward through the rotating shaft 62. During the forward rotation of the rubber roller 63, the contact friction between its outer upper end and the aluminum plate causes the aluminum plate to move automatically from left to right. (The pawl 643, through engagement with the ratchet 641, drives the rubber roller 63 to feed the aluminum plate across a distance greater than that between the leftmost stamping groove 4 and the rightmost stamping groove.) The maximum horizontal distance between 4 is used to automatically move the aluminum plate above the stamping groove 4. When the telescopic end of the external hydraulic rod moves the upper mold 2 to the initial position, the external microcontroller activates the electro-hydraulic push rod 11, causing its telescopic end to move the top seat 12 down to reset, preparing for the next upper synchronous seat 13. During the process of the upper mold moving up and resetting after the aluminum disc is punched, the components cooperate with each other, and the ratchet and pawl engagement and contact friction can automatically perform continuous die punching and conveying of the aluminum disc. The self-feeding of the aluminum plate can be achieved without the need for conveying equipment, reducing the production cost of continuous dies.

[0023] The working principle of the continuous die for producing aluminum discs provided by this utility model is as follows: When the device is used to stamp the aluminum discs, the telescopic end of the external hydraulic rod is first fixed to the upper die 2. Then, the initial end of the aluminum plate passes from left to right through the conveying gap formed by the lower side of the auxiliary seat 65 and the upper outer side of the rubber roller 63 (the auxiliary seat 65 makes the lower side of the aluminum plate in this part press against the upper outer surface of the rubber roller 63, avoiding subsequent stamping and conveying of the aluminum plate by the rubber roller 63). At the same time, the front and rear ends of the aluminum plate are respectively located in the corresponding limiting grooves 16. The limiting grooves 16 limit the longitudinal and vertical movement of the aluminum plate. When stamping the aluminum discs, the telescopic end of the external hydraulic rod causes the upper die 2 to move vertically downward. During the movement, the guide column 14 is driven to engage with the vertically corresponding guide groove 15, thereby ensuring the vertical alignment between the upper mold 2 and the lower mold 1. When the upper mold 2 moves down to a certain extent, the lower side of the rectangular pressure frame 9 contacts the upper side of the aluminum plate of the stamping part of the lower mold 1. As the upper mold 2 continues to move down, the rectangular pressure frame 9 is pressed, and the telescopic end of the telescopic column 2 7 and the spring 2 8 retract. The rectangular pressure frame 9 squeezes and limits the aluminum plate of the stamping part (a rubber strip 10 is provided on the lower side of the rectangular pressure frame 9, which increases the contact resistance between the lower side of the rectangular pressure frame 9 and the upper side of the aluminum plate, further improving the movement limiting effect of the rectangular pressure frame 9 on the aluminum plate), preventing the position from shifting during subsequent stamping. At this time, as the upper mold 2 continues to move down, the rectangular pressure frame 9 is pressed down. As the ratchet bar 643 moves downward, its lower end passes through the clearance groove 646 and presses against the left end of the ratchet 641 (the ratchet bar 643 consists of a strip plate and vertically evenly distributed ratchets). At this time, because the rectangular pressure frame 9 limits the movement of the aluminum plate, the contact friction between the aluminum plate and the outer side of the rubber roller 63 prevents the rotating shaft 62 from driving the ratchet 641 to rotate. Therefore, after being pressed by the ratchet 641, the ratchet bar 643 slides to the left along the L-shaped groove 642 to move and avoid the ratchet 64. The telescopic end of the telescopic column 644 and the spring 645 continue to stretch (the spring 645 is initially in a stretched state). As the upper mold 2 continues to move downward, the upper mold 2 drives its own stamping seat 3 to press against the aluminum plate above the stamping groove 4. The lower end of the stamping seat 3 penetrates into the vertically corresponding stamping groove 4, thereby realizing the stamping and cutting of aluminum discs on the aluminum plate above the stamping groove 4. The generated aluminum discs fall down along the stamping groove 4 onto the inclined surface of the feed chute 5. The aluminum discs are automatically discharged along the inclined surface of the feed chute 5. After the aluminum discs are stamped, the lower side of the synchronous seat 13 contacts the upper side of the top seat 12. As the extension end of the external hydraulic rod drives the upper mold 2 to move upward and reset, the external microcontroller starts the electro-hydraulic push rod 11, causing its extension end to drive the top seat 12 to move upward slightly. The top seat 12 makes contact with the synchronous seat 13 by pressing, thereby causing the synchronous seat 13 to drive the rectangular pressure frame 9 to move upward a certain distance, releasing the movement limit of the rectangular pressure frame 9 on the aluminum plate. Subsequently, as the upper mold 2 moves upward,The pawl 643 engages with the ratchet 641 under the tension and reset force of the spring 645, causing the ratchet 641 to drive the rubber roller 63 to rotate forward via the shaft 62. During the forward rotation of the rubber roller 63, the contact friction between its upper outer end and the aluminum plate causes the aluminum plate to move automatically from left to right (the pawl 643, through engagement with the ratchet 641, drives the rubber roller 63 to convey material across the aluminum plate at a distance greater than the maximum distance formed between the leftmost and rightmost stamping grooves 4), thus automatically moving the aluminum plate above the stamping grooves 4. When the extension end of the external hydraulic rod moves the upper mold 2 to the initial position, the external microcontroller activates the electro-hydraulic push rod 11, causing its extension end to move the top seat 12 downward to reset, preparing for the next upward movement of the synchronous seat 13.

[0024] It is worth noting that the electro-hydraulic actuator 11 disclosed in the above embodiments can be a DYZW integral straight micro electro-hydraulic actuator, and the operation of the electro-hydraulic actuator 11 controlled by an external microcontroller adopts a method commonly used in the prior art.
