Description

Technical Field

[0001] This invention relates to the field of deep drawing die technology, specifically to a stainless steel deep drawing die and method for easy waste removal. Background Technology

[0002] The dies used for deep drawing are called deep drawing dies. Deep drawing dies are specialized tools used to process materials (metal or non-metal) in batches into the required stamped parts. Deep drawing dies can be categorized by their combination into single-operation deep drawing dies, compound dies, and progressive deep drawing dies. They can also be categorized by the stamping equipment used, such as deep drawing dies for single-action presses, double-action presses, and triple-action presses. The main difference between these three types lies in the blank holder device (elastic blank holder and rigid blank holder). Deep drawing dies can also be divided into initial deep drawing dies and dies for subsequent deep drawing operations. The main difference between them lies in the structure and positioning method of the blank holder. Stainless steel is a general term for stainless and acid-resistant steel. Steels resistant to weak corrosive media such as air, steam, and water, or those possessing rust-resistant properties, are called stainless steel. Steels resistant to chemical corrosion media (acids, alkalis, salts, etc.) are called acid-resistant steel.

[0003] Deep drawing dies are used to form stainless steel by pressing it into shape. During the forming process, stainless steel may get stuck inside the deep drawing die, requiring the user to remove it with auxiliary tools. If the stainless steel breaks under pressure during the forming process, it will become even more firmly stuck in the die and difficult to remove, which takes a long time and affects work efficiency. After the stainless steel is formed, there will be excess sheet material on the outside. After cutting it off, it will be in the shape of a ring. The user must draw one ring and then remove it, which is very inconvenient. Summary of the Invention

[0004] The problem this invention aims to solve is that it is inconvenient to remove good material, scrap, and annular edge scrap from the drawing die when drawing stainless steel.

[0005] To solve the above technical problems, the technical solution of the present invention is: a stainless steel deep drawing die and method for convenient cleaning of waste materials, comprising a base plate, a support structure at the upper end of the base plate, cleaning structures on both sides of the outer wall of the support structure, a top plate above the support structure, and a pressing die at the lower end of the top plate. The cleaning structure is driven to move by the downward movement of the pressing die, and the cleaning structure drives the support structure to move when it moves to a certain position.

[0006] The cleaning structure includes a movable ring, a movable rod, a return spring, a soft pad, a pressure block, a threaded rod, a housing, a movable plate, a belt, a cutting blade, a linkage rod, a sliding rod, and a pulley;

[0007] Both ends of the top of the base plate are provided with movable rods, the upper end of the movable rod is provided with a movable ring, and both sides of the lower end of the movable ring are provided with return springs, which are wound around the outer wall of the movable rod.

[0008] A sliding rod is provided on one side of the upper end of the movable ring, and a groove for accommodating the sliding rod is provided on the top of the movable ring.

[0009] Preferably, a soft pad is provided on the top of one side of the slide bar, and the other end of the soft pad is fixedly connected to the upper end of the movable ring. A cutting blade is provided on the upper end of the soft pad, and pressure blocks are provided on the lower ends of both sides of the pressing mold. The pressure blocks correspond to the position of the slide bar.

[0010] The lower end of the movable rod is provided with a movable plate, and the upper end of the movable plate is provided with a linkage rod.

[0011] Preferably, the base plate has a threaded rod inside, the upper end of which is retractable inside the base plate, and the lower end of which penetrates the bottom of the base plate and extends to the outside of the base plate.

[0012] Below the movable plate is a housing, inside which are three pulleys equidistantly arranged. The surfaces of the three pulleys are connected by a belt for transmission. The shafts of the two pulleys on both sides are respectively connected to two corresponding threaded rods. A motor is located at the lower end of the housing, and the shaft of the middle pulley is connected to the output shaft of the motor.

[0013] Preferably, the support structure includes a main rod, a spring plate, a pressure mold, a bracket, a support plate, a connecting plate, an auxiliary rod, a linkage ring, a buffer spring, and a bottom ring.

[0014] Preferably, the upper end of the base plate is provided with a pressure mold, and through slots are provided on both sides of the pressure mold. A main rod is provided at the top of the inner wall of the pressure mold, and a bottom ring is fixedly connected to the bottom end of the main rod. A linkage ring is slidably connected to the outer wall of the main rod.

[0015] Both sides of the linkage ring and the bottom ring are rotatably connected to brackets, and the other end of the brackets is fixedly connected to a support plate. Several buffer springs are equidistantly arranged on one side of the support plate, and the other end of the buffer springs is fixedly connected to a spring plate. The spring plate can be stretched open by the brackets and closely attached to the inner wall of the pressure mold. The spring plate is adapted to the through groove.

[0016] Preferably, a connecting plate is fixedly connected to the inner wall of the pressure mold, one side of the linkage rod is fixedly connected to the front and back of the linkage ring, and an auxiliary rod is slidably connected to the outer wall of the linkage rod, with both ends of the auxiliary rod slidably connected to both sides of the inner wall of the pressure mold.

[0017] Preferably, the lower end of the pressing mold is provided with an opening, the opening of the pressing mold corresponds to the position of the pressure mold, and the inner diameter of the opening is larger than the outer diameter of the pressure mold.

[0018] S1: When in use, first place the stainless steel disc on top of the pressure mold. After placement, control the top plate to move downward through the hydraulic press. The downward movement of the top plate will drive the pressing mold to move downward. The downward movement of the pressing mold will cooperate with the pressure mold and cause the stainless steel disc to undergo deep deformation. As the pressing mold continues to move downward, it will gradually contact the movable ring and cause it to move downward. The movable ring will drive the movable rod to move downward and compress the return spring. The movable rod will drive the movable plate to move downward. The movable plate will drive the motor, threaded rod and sleeve rod to move downward. When the movable ring moves to the limit position, the pressing mold will press the cutting blade. After the cutting blade is initially compressed, it will squeeze the soft pad downward and eventually form a horizontal shape to fit against the top of the movable ring. At the same time as the soft pad fits, it will compress the return spring. The cutting blade will cooperate with the pressure block to cut off the excess plate of the formed stainless steel part. The T-shaped cutting blade will cut it into two semi-circular plates. The excess plates will separate and fall off from the middle break point.

[0019] S2: When the pressing mold and the receiving mold are engaged, the downward movement of the movable ring will also drive the linkage ring in the receiving mold to slide vertically downward along the main rod through its linkage rod. The downward movement of the linkage ring will control the angle of the bracket to decrease and expand outward. After the bracket is expanded, it will drive the support plate to move outward. The support plate will drive the spring plate to move outward. After the spring plate moves out of the through groove opened on one side of the receiving mold, it will lock the inner wall of the formed stainless steel mold through the spring plate. The locked stainless steel mold will be fixed on the receiving mold and will not move downward with the pressing mold.

[0020] S3: If the stainless steel mold breaks under pressure and becomes stuck inside the pressing mold, making it difficult to remove, the pressing mold can be pressed back onto the pressing mold. After pressing, start the motor. The motor will drive the pulley to rotate, which in turn drives the threaded rod to rotate. The rotation of the threaded rod will control the moving plate to move downward. As the moving plate moves, it will cause the support plate to move outward again and expand. After expanding to the maximum extent, turn off the motor and then control the pressing mold to move upward. In this way, the broken stainless steel mold will be left on the pressing mold again. At this time, the user can flip the motor to retract the support plate inward to release the fixation of the stainless steel mold, and then remove the broken stainless steel mold.

[0021] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0022] (1) The base plate is equipped with a cleaning structure and a support structure. When the cleaning structure and the support structure are combined, they can complete the operation by the pressure generated when the pressing mold moves downward. The cleaning structure can cut off the excess plate after the stainless steel mold is formed by the cutting knife, so that it becomes two separate semi-circular rings. Later, the two semi-circular rings can be separated from the cutting point and fall to the outside of the machine by the inclined edge of its soft pad, thus completing the cleaning of excess waste. The support structure can support the inner wall of the stainless steel mold during the forming operation, so that it is fixed on the pressure mold after forming and will not rise. The support structure can also shrink as the pressing mold moves upward until it returns to the initial position. The user can easily remove the stainless steel mold and start the production of the next stainless steel mold, greatly increasing its production efficiency.

[0023] (2) The cleaning structure can also be manually controlled by the motor to open and close the support plate on the support structure. When the stainless steel mold is damaged during deep drawing, the damaged stainless steel mold will be tightly stuck inside the pressing mold. Since the excess plate has been cut at this time, it is very difficult to remove it. Later, the support plate that can be manually controlled to open and close can be reattached and fixed inside the stainless steel mold. At this time, the fixing friction of the support plate is greater than the friction between the stainless steel mold and the inner wall of the pressing mold, so that the stainless steel mold can be smoothly separated from the inside of the pressing mold, saving more time and further preventing the problem of waste material blocking the mold and affecting the work efficiency.

[0024] (3) A buffer spring is provided between the support plate and the spring plate on the support structure. The buffer spring can provide space for the spring plate to move and retract, so as to avoid the support plate opening too far, which would cause the stainless steel mold to deform and affect its appearance. A rubber pad is also provided on the surface of the spring plate. The rubber pad can increase the friction between the spring plate and the inner wall of the stainless steel mold, making it more stable. The opening of the support plate is controlled by the bracket. The movement of the bracket is triangular. The triangular shape has a more stable effect, making its service life longer and the support more firm and stable, and it will not easily loosen.

[0041] like Figures 1 to 13 As shown, the present invention provides a stainless steel deep drawing die and method for convenient cleaning of waste materials, including a base plate 5, a support structure 4 at the upper end of the base plate 5, cleaning structures 3 on both sides of the outer wall of the support structure 4, a top plate 1 above the support structure 4, and a pressing die 2 at the lower end of the top plate 1. The cleaning structure 3 is driven to move by the downward movement of the pressing die 2. When the cleaning structure 3 moves to a certain position, it drives the support structure 4 to move.

[0042] The cleaning structure 3 includes a movable ring 301, a movable rod 302, a return spring 303, a soft pad 304, a pressure block 305, a threaded rod 306, a housing 307, a movable plate 308, a belt 309, a cutting blade 310, a linkage rod 311, a sliding rod 312, and a pulley 313.

[0043] Both ends of the top of the base plate 5 are provided with movable rods 302. The upper end of the movable rod 302 is provided with a movable ring 301. Both sides of the lower end of the movable ring 301 are provided with return springs 303. The return springs 303 are wrapped around the outer wall of the movable rod 302.

[0044] A slide bar 312 is provided on one side of the upper end of the movable ring 301, and a groove for accommodating the slide bar 312 is provided on the top of the movable ring 301.

[0045] A soft pad 304 is provided on the top of one side of the slide bar 312. The other end of the soft pad 304 is fixedly connected to the upper end of the movable ring 301. A cutting blade 310 is provided on the upper end of the soft pad 304. A pressing block 305 is provided on the lower ends of both sides of the pressing mold 2. The pressing block 305 corresponds to the position of the slide bar 312.

[0046] The lower end of the movable rod 302 is provided with a movable plate 308, and the upper end of the movable plate 308 is provided with a linkage rod 311.

[0047] The base plate 5 is provided with a threaded rod 306 inside. The upper end of the threaded rod 306 can extend and retract inside the base plate 5, and the lower end of the threaded rod 306 passes through the bottom of the base plate 5 and extends to the outside of the base plate 5.

[0048] Below the movable plate 308 is a housing 307. Inside the housing 307, three pulleys 313 are equidistantly arranged. The surfaces of the three pulleys 313 are connected by a belt 309. The shafts of the two pulleys 313 on both sides are connected to two corresponding threaded rods 306. A motor is located at the lower end of the housing 307, and the shaft of the middle pulley 313 is connected to the output shaft of the motor.

[0049] The support structure 4 includes a main rod 401, a spring plate 402, a pressure mold 403, a bracket 404, a support plate 405, a connecting plate 406, an auxiliary rod 407, a linkage ring 408, a buffer spring 409, and a bottom ring 410.

[0050] The upper end of the base plate 5 is provided with a pressure mold 403. Both sides of the pressure mold 403 are provided with through slots. The top of the inner wall of the pressure mold 403 is provided with a main rod 401. The bottom end of the main rod 401 is fixedly connected with a bottom ring 410. The outer wall of the main rod 401 is slidably connected with a linkage ring 408. The area of ​​the through slot is slightly larger than the area of ​​the spring plate 402. This slot will not affect the spring plate 402 from moving outward from the inside of the pressure mold 403.

[0051] Both sides of the linkage ring 408 and the bottom ring 410 are rotatably connected to brackets 404. The other end of the bracket 404 is fixedly connected to a support plate 405. Several buffer springs 409 are equidistantly arranged on one side of the support plate 405. The other end of the buffer spring 409 is fixedly connected to a spring plate 402. The spring plate 402 can be opened by the bracket 404 and can be tightly attached to the inner wall of the pressure mold 403. The spring plate 402 is adapted to the through groove. Because the buffer spring 409 is provided between the spring plate 402 and the support plate 405, when the spring plate 402 touches the inner wall of the stainless steel mold, it moves backward and squeezes the buffer spring 409 with the continuous pressure of the support plate 405. The elastic coefficient of the buffer spring 409 will not cause the mold to deform when the spring plate 402 touches the mold, thus affecting the shape of the molded product.

[0052] A connecting plate 406 is fixedly connected to the inner wall of the pressure mold 403. One side of the linkage rod 311 is fixedly connected to the front and back of the linkage ring 408. An auxiliary rod 407 is slidably connected to the outer wall of the linkage rod 311. The two ends of the auxiliary rod 407 are slidably connected to both sides of the inner wall of the pressure mold 403.

[0053] The lower end of the pressing mold 2 has an opening, and the opening of the pressing mold 2 corresponds to the position of the pressure mold 403. The inner diameter of the opening is larger than the outer diameter of the pressure mold 403.

[0054] S1: In use, the stainless steel disc is first placed on top of the pressure mold 403. After placement, the top plate 1 is moved downward by the hydraulic press. The downward movement of the top plate 1 will drive the pressing mold 2 to move downward. The downward movement of the pressing mold 2 will cooperate with the pressure mold 403 and cause the stainless steel disc to undergo deep deformation. As the pressing mold 2 continues to move downward, it will gradually contact the movable ring 301 and cause it to move downward. The movable ring 301 will drive the movable rod 302 to move downward and compress the return spring 303. The movable rod 302 will drive the moving plate 308 to move downward. The motor, threaded rod 306, and sleeve rod move downwards. When the movable ring 301 moves to its limit position, the pressing mold 2 will press the cutting blade 310. After the cutting blade 310 is initially pressed, it will squeeze the soft pad 304 downwards and make it eventually form a horizontal shape to fit against the top of the movable ring 301. At the same time, the soft pad 304 will compress the return spring 303. The cutting blade 310 will cooperate with the pressure block 305 to cut off the excess plate of the formed stainless steel part. The T-shaped cutting blade 310 will cut it into two semi-circular plates, and the excess plates will separate and fall off from the middle break point.

[0055] S2: When the pressing mold 2 and the receiving mold 403 are engaged, the downward movement of the movable ring 301 will also drive the linkage ring 408 in the receiving mold 403 to slide vertically downward along the main rod 401 through its linkage rod 311. The downward movement of the linkage ring 408 will control the angle of the bracket 404 to decrease and expand outward. After the bracket 404 is expanded, it will drive the support plate 405 to move outward. The support plate 405 will drive the spring plate 402 to move outward. After the spring plate 402 moves out of the through groove opened on one side of the receiving mold 403, it will lock the inner wall of the formed stainless steel mold through the spring plate 402. The locked stainless steel mold will be fixed on the receiving mold 403 and will not move downward with the pressing mold 2.

[0056] S3: If the stainless steel mold breaks under pressure and becomes stuck inside the pressing mold 2, making it inconvenient to remove, the pressing mold 2 can be pressed back onto the pressure mold 403. After pressing, start the motor. The motor will drive the pulley 313 to rotate, which in turn drives the threaded rod 306 to rotate. The rotation of the threaded rod 306 will control the moving plate 308 to move downward. As the moving plate 308 moves, it will cause the support plate 405 to move outward again and expand. After expanding to the maximum extent, turn off the motor and then control the pressing mold 2 to move upward. In this way, the broken stainless steel mold will be left on the pressure mold 403 again. At this time, the user can flip the motor to retract the support plate 405 inward to release the fixation of the stainless steel mold and remove the broken stainless steel mold.

[0057] The working principle and usage process of this invention: The user first places the stainless steel disc on top of the pressure mold 403. After placement, the top plate 1 is moved downwards by the hydraulic press. The downward movement of the top plate 1 causes the pressing mold 2 to move downwards. The downward movement of the pressing mold 2 engages with the pressure mold 403, causing the stainless steel disc to undergo deep stretching deformation. As the pressing mold 2 continues to move downwards, it gradually contacts the movable ring 301 and causes it to move downwards. The movable ring 301 then causes the movable rod 302 to move downwards and compress the return spring 303. The movable rod 302 then causes the moving plate 308 to move downwards. The moving plate 308 drives the motor and the threaded rod 30... 6. As the sleeve moves downward, when the movable ring 301 reaches its limit position, the pressing mold 2 will press against the cutting blade 310. Initially compressed, the cutting blade 310 will press downward against the soft pad 304, eventually forming a horizontal shape that fits against the top of the movable ring 301. Simultaneously, the soft pad 304 compresses the return spring 303. The T-shaped cutting blade 310, in conjunction with the pressure block 305, cuts off the excess plate from the formed stainless steel part. The T-shaped cutting blade 310 cuts it into two semi-circular plates, and the excess plates separate and fall off at the joint. When the pressing mold 2 engages with the pressure mold 403, due to the downward movement of the movable ring 301... It also drives the linkage ring 408 inside the pressure mold 403 to slide vertically downwards along the main rod 401 via its linkage rod 311. The downward sliding of the linkage ring 408 controls the angle of the bracket 404 to decrease and expand outwards. After the bracket 404 expands, it drives the support plate 405 to move outwards. The support plate 405 drives the spring plate 402 to move outwards. After the spring plate 402 moves out of the pressure mold 403, it will lock the inner wall of the formed stainless steel mold. The locked stainless steel mold will be fixed on the pressure mold 403 and will not move downwards with the pressing mold 2, which is convenient for demolding. If the stainless steel mold is damaged during pressure and gets stuck inside the pressing mold 2, If it is inconvenient to remove the part, the pressing mold 2 can be pressed back onto the pressure mold 403. After pressing, start the motor. The motor will drive the pulley 313 to rotate, which will drive the threaded rod 306 to rotate. The rotation of the threaded rod 306 will control the moving plate 308 to move downward. As the moving plate 308 moves, it will cause the support plate 405 to move outward again and open up. After opening to the maximum extent, turn off the motor and control the pressing mold 2 to move upward. In this way, the damaged stainless steel mold will be left on the pressure mold 403 again. At this time, the user can flip the motor to retract the support plate 405 inward to release the fixation of the stainless steel mold and remove the damaged stainless steel mold.

A pressing block (305) is provided on the lower end of both sides of the pressing mold (2). The pressing block (305) corresponds to the position of the slide rod (312). The lower end of the movable rod (302) is provided with a movable plate (308), and the upper end of the movable plate (308) is provided with a linkage rod (311).

3. The stainless steel deep drawing die for easy waste removal according to claim 2, characterized in that: The base plate (5) is provided with a threaded rod (306) inside. The upper end of the threaded rod (306) can extend and retract inside the base plate (5), and the lower end of the threaded rod (306) penetrates the bottom of the base plate (5) and extends to the outside of the base plate (5). Below the movable plate (308) is a housing (307), and three pulleys (313) are equidistantly arranged inside the housing (307). The surfaces of the three pulleys (313) are connected by a belt (309). The shafts of the pulleys (313) on both sides are connected to two corresponding threaded rods (306). A motor is provided at the lower end of the housing (307), and the shaft of the middle pulley (313) is connected to the output shaft of the motor.

4. The method of using a stainless steel deep drawing die for easy waste removal according to claim 1, characterized in that: The operational process steps are as follows: S1: When using, first place the stainless steel disc on top of the pressure mold (403). After placement, control the top plate (1) to move downwards using a hydraulic press. The downward movement of the top plate (1) will drive the pressing mold (2) to move downwards. The downward movement of the pressing mold (2) will engage with the pressure mold (403) and cause the stainless steel disc to undergo deep deformation. As the pressing mold (2) continues to move downwards, it will gradually contact the movable ring (301) and cause it to move downwards. The movable ring (301) will drive the movable rod (302) to move downwards and compress the return spring (303). The movable rod (302) will drive the moving plate (308) to move downwards. The moving plate (308) will move downwards. 8) Drive the motor, threaded rod (306) and sleeve rod to move downward. When the movable ring (301) moves to the limit position, the pressing mold (2) will press the cutting knife (310). After the cutting knife (310) is initially pressed, it will squeeze the soft pad (304) downward and make it eventually form a horizontal shape to fit against the top of the movable ring (301). While the soft pad (304) is in contact, it will compress the return spring (303). The cutting knife (310) will cooperate with the pressure block (305) to cut off the excess plate of the formed stainless steel part. The T-shaped cutting knife (310) will cut it into two semi-circular plates. The excess plates will separate and fall off from the middle break point. S2: When the pressing mold (2) and the receiving mold (403) are engaged, the downward movement of the movable ring (301) will also drive the linkage ring (408) in the receiving mold (403) to slide vertically downward along the main rod (401) through its linkage rod (311). The downward movement of the linkage ring (408) will control the angle of the bracket (404) to decrease and expand outward. After the bracket (404) is expanded, it will drive the support plate (405) to move outward. The support plate (405) will drive the spring plate (402) to move outward. After the spring plate (402) moves out of the through groove opened on one side of the receiving mold (403), it will lock the inner wall of the formed stainless steel mold through the spring plate (402). The locked stainless steel mold will be fixed on the receiving mold (403) and will not move downward with the pressing mold (2). S3: If the stainless steel mold breaks under pressure and gets stuck inside the pressing mold (2), making it inconvenient to remove, the pressing mold (2) can be pressed back onto the pressure mold (403). After pressing, start the motor. The motor will drive the pulley (313) to rotate. The pulley (313) will drive the threaded rod (306) to rotate. The rotation of the threaded rod (306) will control the moving plate (308) to move downward. As the moving plate (308) moves, it will cause the support plate (405) to move outward again and open. After opening to the maximum extent, turn off the motor and control the pressing mold (2) to move upward. In this way, the broken stainless steel mold will be left on the pressure mold (403). At this time, the user can flip the motor to retract the support plate (405) inward to release the fixation of the stainless steel mold and remove the broken stainless steel mold.
