[0019] The present invention has the following beneficial effects:

[0020] 1. In the present invention, when the upper mold punches the plate, the area of ​​the plate punched by the upper mold will enter the interior of the mold groove, and then when the upper mold moves downward, the plate will squeeze the multiple semicircular plates. When the multiple semicircular plates are squeezed, they will move outward in the opposite direction on the top of the partition. When the multiple semicircular plates move outward, the movement of the semicircular plates will squeeze the elastic plate to cause it to deform. At the same time, when the multiple semicircular plates continue to move outward, the movement of the semicircular plates will push the telescopic ring to move upward inside the conical groove through the rotating plate. When the telescopic ring moves, the movement of the telescopic ring will follow the inclined surface of the rear wall of the conical groove, thereby causing relative contraction and squeezing the bottom of the rubber ring. The rubber ring is coated on the outer surface of the cylindrical structure formed by stamping. Then, when the nickel plate continues to be stamped, the nickel plate will squeeze the push plate. After being squeezed, the push plate will push the flat plate downward. At this time, the stamped nickel plate will form a cylindrical shape inside the mold groove. At the beginning of stamping, the arcs on the four semicircular plates can play a certain initial positioning role for the nickel plate to prevent the nickel plate from shifting before stamping. Then, when the nickel cylinder is subjected to the pressure of stamping, the expansion ring is tightly coated on the surface of the nickel cylinder, which can reduce the situation in which the outer contour of the plate expands when the nickel cylinder material is stamped downward, resulting in wrinkles on the cylinder surface after stamping, thereby improving the forming quality and efficiency during stamping.

[0021] When the upper mold is separated from the nickel-copper, the strong spring at the bottom of the flat plate will push the flat plate and drive the pushing plate to move upward through the flat plate, and when the upper mold is separated from the nickel-copper, the strong spring at the bottom of the flat plate will push the flat plate and drive the pushing plate to move upward through the flat plate. When the flat plate moves upward, the L plate will drive the arc plate to move upward, and when the flat plate moves upward, it will drive the obtuse plate to move upward and reset. When the obtuse plate moves upward, it will first pull the arc plate upward through the L plate and the connecting plate. When the arc plate is pulled upward by the connecting plate, it will be squeezed by the protrusion of the triangular plate on the inner wall of the Z-shaped groove. When the arc plate is squeezed by the protrusion of the triangular plate, the arc plate will push the rubber block to extend out of the outer wall of the Z-shaped groove and fit on the outer surface of the nickel cylinder and increase the friction between the rubber block and the outer surface of the nickel copper. Then, when the flat plate continues to move upward, the L plate will drive the arc plate to move upward. When the arc plate moves, it will drive the nickel copper to move upward through the rubber block. At the same time, combined with the upward movement of the pushing plate, the nickel cylinder can be separated from the mold groove from multiple directions to ensure that the nickel cylinder can be demoulded smoothly, reduce the demoulding difficulties caused by the elastic rebound force when the nickel cylinder is stamped, reduce the residence time of the nickel cylinder in the mold, and speed up the production rhythm and improve production efficiency.

[0022] 3. In the present invention, when the rotating plate pushes the telescopic ring to move upward, the telescopic ring will squeeze the bottom of the elliptical ring, and after the bottom of the elliptical ring is squeezed, it will squeeze the top inner wall of the conical groove. At this time, the elliptical ring will be affected by the obtuse inclination of the top inner wall of the conical groove and thus move backward to a certain extent. When the elliptical ring is squeezed, the elastic inclined plate will be pushed to move in the direction of the rubber ring through the elastic plate 2. When the elastic inclined plate moves, the elastic inclined plate will squeeze the rubber ring through the spring plate. Since the rubber ring has been attached to the outer surface of the stamped nickel cylinder, when the spring plate is When the elastic inclined plate is extruded, the elastic inclined plate will produce an outward bulge. At this time, the bulged spring plate will make large-area contact with the side wall of the rubber ring and be extruded toward the nickel cylinder through the rubber ring. When the spring plate expands and the inner cylinder is extruded through the rubber ring, the rubber ring can squeeze the nickel cylinder from different directions, which can reduce the elastic reset of the top end of the nickel cylinder after demolding and reduce its recovery to the state before deformation, which helps to maintain the shape of the nickel cylinder and reduce the dimensional change and shape deviation caused by the elastic reset, thereby better ensuring the dimensional accuracy and shape accuracy of the nickel cylinder.

[0046] A method for using a nickel cylinder production device, the nickel cylinder production device, the method comprising the following steps:

[0047] S1: Place materials;

[0048] S2: start stamping;

[0049] S3: Compression molding.

[0050] When in use, first place the nickel plate to be stamped on the bottom inner wall of the main body 1, then start the main body 1 so that the main body 1 drives the upper mold 101 to move up and down. When the upper mold 101 moves downward, the nickel plate will be squeezed into the inside of the mold groove 102. Then, the nickel plate entering the mold groove 102 will be stamped into a corresponding shape as the upper mold 101 moves downward, thereby completing the stamping purpose.

[0051] When the upper mold 101 punches the sheet, the area of ​​the sheet punched by the upper mold 101 will enter the interior of the mold groove 102, and then when the upper mold 101 moves downward, the sheet will squeeze the multiple semicircular plates 301. When the multiple semicircular plates 301 are squeezed, they will move outward in the opposite direction on the top of the partition 103. When the multiple semicircular plates 301 move outward, the movement of the semicircular plates 301 will squeeze the elastic plate 305 to cause it to deform. At the same time, when the multiple semicircular plates 301 continue to move outward, the movement of the semicircular plates 301 will push the telescopic ring 502 to move upward inside the conical groove 105 through the rotating plate 501. When the telescopic ring 502 moves, the movement of the telescopic ring 502 will follow the inclined surface of the rear wall of the conical groove 105, thereby causing relative contraction and The bottom of the rubber ring 504 is squeezed so that the rubber ring 504 is covered on the outer surface of the cylindrical structure formed by stamping. Then, when the nickel plate is continuously stamped, the nickel plate will squeeze the push plate 201. After being squeezed, the push plate 201 will push the flat plate 202 to move downward. At this time, the stamped nickel plate will form a cylindrical shape inside the mold groove 102. At the beginning of stamping, the arcs and on the four semicircular plates 301 can play a certain initial positioning role for the nickel plate to prevent the nickel plate from being offset before stamping. Then, when the nickel cylinder is subjected to the pressure of stamping, the telescopic ring 502 is tightly covered on the surface of the nickel cylinder, which can reduce the situation in which the outer contour of the plate material expands when the nickel cylinder material is stamped downward, resulting in wrinkles on the cylinder surface after stamping, thereby improving the forming quality and efficiency during stamping.

[0052] When the top of the push plate 201 is squeezed by the plate, the flat plate 202 is driven to move downward. When the flat plate 202 moves downward, the obtuse plate 304 is driven to move downward through the sliding groove 203. When the obtuse plate 304 moves downward, its top will slide downward on the surface of the guide rail 303. When the obtuse plate 304 slides downward, the downward sliding of the obtuse plate 304 will drive the L plate 401 to move downward synchronously inside the Z-shaped groove 302. When the L plate 401 moves downward, the L plate 401 squeezes the arc plate 403 through the connecting plate 402. At this time, the arc plate 403 is squeezed by the connecting plate 402. When the connecting plate 402 is pressed downward, it will separate from the triangular plate on the inner wall of the Z-shaped groove 302. At this time, the arc plate 403 will be pushed by the connecting plate 402 to produce a bulging deformation in the direction of the triangular plate. At this time, the deformed arc plate 403 will drive the rubber block 405 to shrink into the inside of the Z-shaped groove 302. Then, after the nickel plate is stamped, the main body 1 will drive the upper mold 101 to move up and reset. At this time, the upper mold 101 will separate from the nickel cylinder. When the upper mold 101 separates from the nickel copper, the strong spring at the bottom of the flat plate 202 will push the flat plate 202 and drive it through the flat plate 202. The push plate 201 moves upward, and when the push plate 201 moves upward, it will push the bottom of the nickel cylinder upward. When the flat plate 202 moves upward, it will drive the obtuse plate 304 to move upward and reset. When the obtuse plate 304 moves upward, it will first pull the arc plate 403 upward through the L plate 401 and the connecting plate 402. When the arc plate 403 is pulled upward by the connecting plate 402, it will be squeezed by the protrusion of the triangular plate on the inner wall of the Z-shaped groove 302. When the arc plate 403 is squeezed by the protrusion of the triangular plate, the arc plate 403 will push the rubber block 405 to extend out of the outer wall of the Z-shaped groove 302 and fit The friction between the rubber block 405 and the outer surface of the nickel copper is increased on the outer surface of the nickel cylinder. Then, when the flat plate 202 continues to move upward, the L plate 401 will drive the arc plate 403 to move upward. When the arc plate 403 moves, it will drive the nickel copper to move upward through the rubber block 405. At the same time, combined with the upward movement of the push plate 201, the nickel cylinder can be separated from the mold groove 102 from multiple directions to ensure that the nickel cylinder can be demolded smoothly, reduce the demolding difficulties caused by the elastic rebound force when the nickel cylinder is stamped, reduce the residence time of the nickel cylinder in the mold, and speed up the production rhythm and improve production efficiency.

[0053] When the rotating plate 501 pushes the telescopic ring 502 to move upward, the telescopic ring 502 will squeeze the bottom of the elliptical ring 503. After the bottom of the elliptical ring 503 is squeezed, it will squeeze the top inner wall of the conical groove 105. At this time, the elliptical ring 503 will be affected by the obtuse inclination of the top inner wall of the conical groove 105 and thus move backward to a certain extent. When the elliptical ring 503 is squeezed, the elastic inclined plate 602 will be pushed to move toward the direction of the rubber ring 504 through the elastic plate 2 601. When the elastic inclined plate 602 moves, the elastic inclined plate 602 will squeeze the rubber ring 504 through the spring plate 603. Since the rubber ring 504 has been attached to the outer surface of the stamped nickel cylinder , then when the spring plate 603 is squeezed by the elastic inclined plate 602, the elastic inclined plate 602 will bulge outward. At this time, the bulged spring plate 603 will make large-area contact with the side wall of the rubber ring 504 and squeeze the nickel tube through the rubber ring 504. When the spring plate 603 expands and squeezes the inner tube through the rubber ring 504, the rubber ring 504 can squeeze the nickel tube from different directions, which can reduce the elastic reset of the top end of the nickel tube after demolding and reduce its recovery to the state before deformation, which helps to maintain the shape of the nickel tube and reduce the dimensional change and shape deviation caused by the elastic reset, thereby better ensuring the dimensional accuracy and shape accuracy of the nickel tube.
