Description

Technical Field

[0001] This utility model relates to the field of stamping dies, specifically a multi-station stamping die. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] According to Chinese Patent No. CN216027553U, a rotary multi-station stamping die is disclosed. This utility model starts the rotating motor by operating the control panel, which drives the turntable to rotate. The four limiting parts on the turntable enable the device to feed and collect materials during the stamping process, thereby speeding up the overall stamping speed and improving stamping efficiency.

[0004] Regarding the aforementioned patent content, by setting up a fixed cylinder and a movable cylinder, the debris generated by the stamping head during the stamping operation can be blocked by the movable cylinder if it splashes, thereby avoiding injury to the workers. However, the splashed debris may adhere to the movable cylinder. Since the stamping head is located inside the fixed cylinder and the movable cylinder, the workers are restricted by the stamping head and find it inconvenient to clean the debris adhering to the inner wall of the movable cylinder, thereby reducing the cleaning efficiency of the debris inside the movable cylinder. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a multi-station stamping die to solve the technical problem of inconvenience in cleaning debris adhering to the inner wall of the moving cylinder.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-station stamping die, comprising a base plate and a movable plate, wherein a stamping head and a fixed cylinder are respectively installed on the bottom of the movable plate, a protective cylinder is sleeved on the outer wall of the fixed cylinder, and a scraping assembly is provided at the bottom of the protective cylinder, the scraping assembly comprising a scraping ring installed at the bottom of the fixed cylinder, a threaded groove opened at the bottom of the protective cylinder, and a silicone pad installed on the inner wall of the protective cylinder, wherein a threaded ring is threadedly connected inside the threaded groove, and a collecting ring is installed at the bottom of the threaded ring, and a collecting groove is opened at the top of the collecting ring.

[0007] By adopting the above technical solution, when it is necessary to clean the debris collected inside the collection tank, the staff can rotate the collection ring so that the threaded ring is unscrewed from the threaded groove, and then the collection ring can be removed to clean the debris inside the collection tank.

[0008] Furthermore, a support frame is installed on one side of the top of the base plate, a hydraulic cylinder is installed on the top of the support frame, and a movable plate is installed at the output end of the hydraulic cylinder through a piston rod.

[0009] By adopting the above technical solution, when stamping is required, the operator can activate the hydraulic cylinder to extend the piston rod, thereby driving the movable plate to move down, and then driving the stamping head to move down.

[0010] Furthermore, both sides of the fixed cylinder are provided with sliding grooves, and a slider is provided inside the sliding groove. One side of the slider is fixedly connected to the protective cylinder.

[0011] By adopting the above technical solution, when the protective cylinder moves, it will drive the slider to slide inside the groove, thereby improving the stability of the protective cylinder when it moves.

[0012] Furthermore, a motor is installed on the top of the base plate, and the output end of the motor is connected to a turntable, the top of which has four mold cavities.

[0013] By adopting the above technical solution, when the turntable needs to rotate, the staff can start the motor, and the motor can drive the turntable to rotate.

[0014] Furthermore, two support seats are also installed on the top of the base plate, and the top of the support seats is in contact with the bottom of the turntable.

[0015] By adopting the above technical solution, the support base can support the turntable.

[0016] Furthermore, the top of the base plate is provided with an annular groove, and multiple movable blocks are arranged inside the annular groove. A support rod is installed between the movable blocks and the turntable.

[0017] By adopting the above technical solution, when the turntable rotates, it will drive the support rod to rotate, and then drive the movable block to slide inside the annular groove, thereby improving the stability of the turntable when it rotates.

[0018] Furthermore, multiple springs are installed at the bottom of the turntable, and the bottom end of the springs is connected to a push plate. A push rod that penetrates into the mold cavity is installed at the top of the push plate.

[0019] By adopting the above technical solution, when it is necessary to clean the debris accumulated inside the mold cavity, the worker pushes the push plate upward. The push plate moves upward, causing the push rod to move upward and squeeze the spring, so that the spring is compressed.

[0020] Furthermore, a top plate is installed at the top of the push rod, and the outer wall of the top plate is in contact with the inner wall of the mold cavity.

[0021] By adopting the above technical solution, when the push rod moves upward, it will drive the top plate to move upward, and the top plate can push out the debris accumulated inside the mold cavity.

[0022] Furthermore, the stamping head is located inside the fixed cylinder and the protective cylinder.

[0023] By adopting the above technical solution, the fixed cylinder and the protective cylinder can protect the stamping head.

[0024] Furthermore, the outer wall of the scraper ring is in contact with the inner wall of the silicone pad, and the collection groove is located directly below the scraper ring.

[0025] By adopting the above technical solution, the scraper ring can scrape off the debris attached to the silicone pad so that the debris can fall into the collection tank.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model incorporates a scraping component. Due to the silicone pad, debris splashed during the stamping process can be blocked by the silicone pad. The blocked debris may fall directly into the collection tank, while some debris may adhere to the silicone pad. When it is necessary to clean the debris on the silicone pad, the operator only needs to push the protective cylinder upwards, causing it to move upwards. At this time, the scraping ring can scrape off the debris attached to the silicone pad and cause it to fall into the collection tank. This method can clean the debris attached to the silicone pad, avoiding some debris from remaining attached to the protective cylinder and being difficult to clean, thus improving the cleaning efficiency of debris inside the protective cylinder.

[0028] 2. This utility model has a threaded groove and a threaded ring. When it is necessary to clean the debris collected inside the collection tank, the worker can rotate the collection ring so that the threaded ring is unscrewed from the threaded groove. Then the collection ring can be removed to clean the debris inside the collection tank. The disassembly and assembly process is simple and convenient. Attached Figure Description

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0038] The embodiments of this utility model will be described below based on its overall structure.

[0039] Example 1:

[0040] A multi-station stamping die, such as Figures 1-7 As shown, the device includes a base plate 1 and a movable plate 5. A punching head 7 and a fixed cylinder 8 are respectively installed at the bottom of the movable plate 5. A protective cylinder 23 is fitted on the outer wall of the fixed cylinder 8, and a scraper assembly 9 is provided at the bottom of the protective cylinder 23. A support frame 2 is installed on one side of the top of the base plate 1. A hydraulic cylinder 4 is installed on the top of the support frame 2, and the output end of the hydraulic cylinder 4 is connected to the movable plate 5 through the piston rod. Guide rods 6 that pass through the support frame 2 are installed on both sides of the top of the movable plate 5. When punching is required, the operator can start the hydraulic cylinder 4 to extend the piston rod, thereby moving the movable plate 5 downward and then moving the punching head 7 downward. A motor 11 is installed on the top of the base plate 1, and the output end of the motor 11 is connected to a turntable 10. The top of the turntable 10 has four mold cavities 16. When the turntable 10 needs to be rotated, the operator can start the motor 11, and the operation of the motor 11 can drive the turntable 10 to rotate.

[0041] See Figures 1-4Two support seats 12 are installed on the top of the base plate 1, and the top of the support seats 12 is equipped with rubber pads. The top of the support seats 12 fits against the bottom of the turntable 10, and the support seats 12 can support the turntable 10. An annular groove 13 is also opened on the top of the base plate 1, and multiple movable blocks 14 are set inside the annular groove 13. The movable blocks 14 are slidably connected to the annular groove 13. A support rod 15 is installed between the movable block 14 and the turntable 10. When the turntable 10 rotates, it will drive the support rod 15 to rotate, and then drive the movable block 14 to slide inside the annular groove 13, thereby improving the stability of the turntable 10 when rotating. The punch head 7 is located inside the fixed cylinder 8 and the protective cylinder 23 so that the fixed cylinder 8 and the protective cylinder 23 can protect the punch head 7. A control panel 3 is installed on the outer surface of the support frame 2, and the control panel 3 is electrically connected to the hydraulic cylinder 4 and the motor 11 respectively, so that the operator can start or stop the hydraulic cylinder 4 and the motor 11 through the control panel 3.

[0042] Specifically, the scraping assembly 9 includes a scraping ring 901 installed at the bottom of the fixed cylinder 8, a threaded groove 905 opened at the bottom of the protective cylinder 23, and a silicone pad 906 installed on the inner wall of the protective cylinder 23. A threaded ring 904 is threadedly connected inside the threaded groove 905, and a collecting ring 902 is installed at the bottom of the threaded ring 904. A collecting groove 903 is opened at the top of the collecting ring 902. When it is necessary to clean the debris collected inside the collecting groove 903, the operator can rotate the collecting ring 902 so that the threaded ring 904... Unscrew the collection ring 902 from inside the threaded groove 905 to clean the debris inside the collection groove 903. The outer wall of the scraper ring 901 fits against the inner wall of the silicone pad 906. The collection groove 903 is located directly below the scraper ring 901 so that the scraper ring 901 can scrape off the debris attached to the silicone pad 906 so that the debris can fall into the collection groove 903. The collection ring 902 is detachably connected to the protective cylinder 23 via the threaded ring 904, which facilitates the disassembly of the collection ring 902.

[0043] Example 2:

[0044] Based on the above embodiment 1, in order to improve the stability of the protective cylinder 23 when it moves, it needs to be guided, so the following structure will be set.

[0045] Specifically, both sides of the fixed cylinder 8 are provided with sliding grooves 21, and a slider 22 is provided inside the sliding groove 21. One side of the slider 22 is fixedly connected to the protective cylinder 23. The protective cylinder 23 is slidably connected to the sliding groove 21 through the slider 22. When the protective cylinder 23 moves, it will drive the slider 22 to slide inside the sliding groove 21, thereby improving the stability of the protective cylinder 23 when it moves.

[0046] Example 3:

[0047] Based on the above embodiment 1, the following structure will be set to facilitate the cleaning of debris inside the mold cavity 16.

[0048] See Figures 1-4 The bottom of the turntable 10 is equipped with multiple springs 18, and the bottom end of the springs 18 is connected to a push plate 20. The top of the push plate 20 is equipped with a push rod 19 that penetrates into the mold cavity 16. When it is necessary to clean the debris accumulated inside the mold cavity 16, the worker pushes the push plate 20 upward. The push plate 20 moves upward, causing the push rod 19 to move upward and squeeze the springs 18, so that the springs 18 are compressed. The top of the push rod 19 is equipped with a top plate 17. The outer wall of the top plate 17 fits against the inner wall of the mold cavity 16. When the push rod 19 moves upward, it will drive the top plate 17 to move upward. The top plate 17 can push out the debris accumulated inside the mold cavity 16, and then the worker can clean the debris accumulated on the top plate 17.

[0049] The working principle of this utility model is as follows: First, when using it, turn on the power supply, then put the object into the mold cavity 16, then start the hydraulic cylinder 4. The operation of the hydraulic cylinder 4 can extend the piston rod, thereby driving the movable plate 5 to move down, and then driving the punch head 7, the fixed cylinder 8 and the protective cylinder 23 to move down. The protective cylinder 23 first contacts the turntable 10. As the punch head 7 and the fixed cylinder 8 continue to move down, the punch head 7 can perform the punching operation. During the punching process, the splashed debris will be blocked by the protective cylinder 23. Some of the blocked debris will fall directly into the collection tank 903, while some debris may adhere to the silicone pad 906.

[0050] After the stamping is completed, the hydraulic cylinder 4 can retract the piston rod, which in turn drives the movable plate 5 to move upward, and drives the stamping head 7 and the fixed cylinder 8 to move upward, and then drives the protective cylinder 23 to move upward. Then the motor 11 is started, and the motor 11 drives the turntable 10 to rotate. The turntable 10 drives the mold cavity 16 to rotate. When the stamped object moves away from under the stamping head 7 and the object to be stamped is just rotated to the right under the stamping head 7, the motor 11 is turned off, and then the hydraulic cylinder 4 is started again. The above steps are repeated to make the stamping head 7 move downward to perform the stamping operation. During the stamping process, the operator can take out the stamped object and put the object to be stamped into the mold cavity 16. In this way, the stamping operation of the next object can be performed quickly.

[0051] When it is necessary to clean the debris on the silicone pad 906, the operator only needs to push the protective cylinder 23 upward, so that the protective cylinder 23 moves upward. At this time, the scraper ring 901 can scrape off the debris attached to the silicone pad 906 and let the debris fall into the collection tank 903. When it is necessary to clean the debris collected in the collection tank 903, the operator can rotate the collection ring 902 so that the threaded ring 904 can be unscrewed from the threaded groove 905. Then the collection ring 902 can be removed to clean the debris inside the collection tank 903.

[0052] When it is necessary to clean the debris accumulated inside the mold cavity 16, the worker pushes the push plate 20 upward. The push plate 20 moves upward, causing the push rod 19 to move upward and compress the spring 18. When the push rod 19 moves upward, it will cause the top plate 17 to move upward. The top plate 17 can then push out the debris accumulated inside the mold cavity 16, and then the worker can clean the debris accumulated on the top plate 17.
