[0037] The following is for reference. Figure 1 and Figure 2 This invention describes a high-cylinder cup stamping device according to an embodiment of the present invention.
[0038] like Figure 1 and Figure 2 As shown, the high-cylinder cup stamping device according to an embodiment of the present invention includes a cup product 100 and a two-stage die 300.
[0039] The cup product 100 has side walls that sequentially include a first side wall 110, a bending portion 120, and a second side wall 130. The two-punch die 300 includes a two-punch upper die 310 and a two-punch lower die 320. The two-punch upper die 310 includes a two-punch upper die cylinder 311. The inner side wall of the two-punch upper die cylinder 311 abuts against the outer side wall of the second side wall 130. The lower end of the two-punch upper die cylinder 311 abuts against the outer side wall of the bending portion 120. The two-punch lower die 320 includes a two-punch lower die core 321 and a two-punch lower die sleeve 322. The two-punch lower die sleeve 322 is fitted onto the outer side of the two-punch lower die core 321. The outer side wall of the upper side of the two-punch lower die core 321 abuts against the inner side wall of the second side wall 130. The outer side wall of the two-punch lower die sleeve 322 corresponds to the inner side wall of the first side wall 110. The upper end of the two-punch lower die sleeve 322 abuts against the inner side wall of the bending portion 120.
[0040] For example, such as Figure 1 and Figure 2 As shown, cup product 100 is the finished product after processing. (Refer to...) Figure 3 The cup product 100 is manufactured by sequentially stamping aluminum foil 101, and its sidewalls sequentially include a first sidewall 110, a bent portion 120, and a second sidewall 130. (Refer to...) Figure 5The two-punch die 300 includes an upper two-punch die 310 and a lower two-punch die 320. The upper two-punch die 310 is a movable die that can move up and down, while the lower two-punch die 320 is a fixed die that remains stationary. The upper two-punch die 310 includes an upper two-punch die cylinder 311. The inner wall of the upper two-punch die cylinder 311 abuts against the outer wall of the second side wall 130, and the lower end of the upper two-punch die cylinder 311 abuts against the outer wall of the bending portion 120, which means that the inner wall of the upper two-punch die cylinder 311 forms the outer wall of the second side wall 130 of the cup product 100. The lower two-punch die 320 includes a lower two-punch die core 321 and a lower two-punch die sleeve 322. The lower two-punch die sleeve 322 is fitted onto the outside of the lower two-punch die core 321 and can move up and down relative to the lower two-punch die core 321. The outer wall of the upper side of the lower two-punch die core 321 abuts against the inner wall of the second side wall 130. The outer wall of the second punch lower die sleeve 322 corresponds to the inner wall of the first side wall 110, and the upper end of the second punch lower die sleeve 322 abuts against the inner wall of the bending part 120.
[0041] The cup product 100 needs to be stamped using aluminum foil 101. In order to ensure that the tall cup-shaped cup product 100 can be formed smoothly, the bent part 120 and the second side wall 130 of the cup product 100 are processed first by the two-stage die 300. This can effectively reduce the breakage of the cup product 100 during the stamping process.
[0042] Reference Figure 5 , Figure 8 The cup product 100 to be processed is placed on the two-punch lower die 320, with the opening of the cup product 100 facing downwards and the upper end of the two-punch lower die core 321 inserted into the inner cavity of the cup product 100. In this way, the second side wall 130 of the cup product 100 faces upwards and the first side wall 110 faces downwards. At this time, the two-punch upper die 310 is in the raised and open state.
[0043] Reference Figure 5 , Figure 9 The upper die 310 is pressed down to close the mold. Then, the inner wall of the upper die cylinder 311, in conjunction with the outer wall of the lower die core 321, clamps the two sides of the second side wall 130 to form the second side wall 130. Simultaneously, the lower end of the upper die cylinder 311, in conjunction with the upper end of the lower die sleeve 322, clamps the two sides of the bent portion 120 to form the bent portion 120. At this time, the outer wall of the lower die sleeve 322 corresponds to the inner wall of the first side wall 110. Essentially, the lower die sleeve 322 can limit the position of the first side wall 110, but it does not clamp the first side wall 110 for forming.
[0044] Through the above process, when stamping the cup product 100, the second side wall 130 position is first formed by the second die 300. In this way, when the cup product 100 is stamped as a whole, it is not easy for damage to occur, thus ensuring the yield of the stamping work.
[0045] In some embodiments of this utility model, reference is made to Figure 2 , Figure 4 The present invention also includes a punch 200 for initially punching aluminum foil 101 into the inner cavity 140 and bottom wall 150 of the cup product 100. The punch 200 includes an upper punch 210 and a lower punch 220. The upper punch 210 includes an upper punch cylinder 211, and an upper punch template 212 is provided inside the upper punch cylinder 211. The upper punch template 212 abuts against the outer bottom wall 150 of the cup product 100, and the inner side wall of the upper punch cylinder 211 abuts against the outer side wall of the cup product 100. The lower punch 221 includes a lower punch core 221, and the lower punch core 221 abuts against the inner side wall of the cup product 100. One upper die 210 serves as the moving die, and the other lower die 220 serves as the fixed die. When the upper die 210 and the lower die 220 are closed, the upper die plate 212 of the upper die 210 cooperates with the lower die core 221 to form the outer bottom wall 150 of the cup product 100. The inner side wall of the upper die cylinder 211 cooperates with the outer side wall of the lower die core 221 to form the side wall and inner cavity 140 of the cup product 100.
[0046] When the upper die 210 and the lower die 220 are in the open state, the aluminum foil 101 is first placed on the lower die 220. Then the upper die 210 descends to close the mold. First, the upper die plate 212 and the lower die core 221 clamp the aluminum foil 101. Then the upper die cylinder 211 continues to descend, which can bend the aluminum foil 101 to form the inner cavity 140 and the bottom wall 150, completing the initial stamping work of the cup product 100.
[0047] In some embodiments of this utility model, a punch die core 221 is fitted with a punch die sleeve 222, and a punch die sleeve plate 223 is provided on the outside of the punch die sleeve 222. The punch die sleeve plate 223 can be bent to form the opening bending edge 160 of the cup product 100, and the upper side of the punch die sleeve plate 223 abuts against the lower side of the opening bending edge 160.
[0048] When the upper die 210 descends to close the mold, the upper die cylinder 211 descends to bend the aluminum foil 101 into the inner cavity 140. At the same time, the lower end of the upper die cylinder 211 cooperates with the upper side of the lower die sleeve 223 to bend the opening bend edge 160 of the cup product 100. The opening bend edge 160 can strengthen the structural strength of the cup mouth of the cup product 100.
[0049] In a further embodiment of this utility model, an upper pressure plate 213 is provided at the lower end of an upper die cylinder 211. The lower side of the upper pressure plate 213 cooperates with the upper side of a lower die sleeve plate 223 to bend the opening bending edge 160 of the cup product 100, thus ensuring that the opening bending edge 160 is sufficiently flat.
[0050] In some embodiments of this utility model, reference is made to Figure 5 , Figure 8 , Figure 9 The upper die cylinder 311 is provided with an upper die plate 312. The upper die plate 312 presses against the outer bottom wall of the cup product 100, ensuring that when the upper die 310 and the lower die 320 are closed, the upper die plate 312 and the lower die core 321 can press against the bottom wall 150 of the cup product 100, thereby ensuring the forming effect of the bottom wall 150.
[0051] In some embodiments of this utility model, the lower die sleeve 322 is fitted with a lower die outer sleeve 324. The upper side of the lower die outer sleeve 324 abuts against the lower side of the opening bending edge 160, ensuring that when the upper die 310 and the lower die 320 are closed, the lower die outer sleeve 324 can hold the opening bending edge 160 of the cup product 100, thus ensuring that the cup product 100 will not shift when the mold is closed, and also ensuring that the forming effect of the opening bending edge 160 can be maintained.
[0052] In some embodiments of this utility model, a bottom plate 323 for the lower die sleeve 322 is provided on the outer side of the lower side of the lower die sleeve 322, and a buffer spring 325 is provided between the upper side of the bottom plate 323 and the lower side of the outer die sleeve 324. During the stamping process of the second die 300, the side wall height of the cup product 100 may change. The buffer spring 325 between the bottom plate 323 and the outer die sleeve 324 allows the outer die sleeve 324 to be finely adjusted to accommodate changes in the side wall height of the cup product 100.
[0053] In some embodiments of this utility model, a buffer screw 326 is provided between the upper side of the bottom plate 323 of the second-punch lower die sleeve and the lower side of the outer plate 324 of the second-punch lower die sleeve. A buffer spring 325 is fitted onto the buffer screw 326. A guide sleeve 327 is provided on the bottom plate 323 of the second-punch lower die sleeve. The upper end of the buffer screw 326 is threadedly connected to the outer plate 324 of the second-punch lower die sleeve, and the lower side of the buffer screw 326 slides into the guide sleeve 327. The guide sleeve 327 can guide the buffer screw 326 to rise and fall, thereby ensuring that the rising and falling process of the outer plate 324 of the second-punch lower die sleeve is sufficiently accurate, and avoiding the offset of the bottom plate 323 of the second-punch lower die sleeve, which would affect the forming effect of the cup product 100.
[0054] In some embodiments of this utility model, reference is made to Figure 2 , Figure 6The present invention's high-cylinder cup stamping device further includes a three-punch die 400, which is used for forming the outer side of the cup product 100. The three-punch die 400 includes an upper three-punch die 410 and a lower three-punch die 420. The upper three-punch die 410 includes an upper three-punch die cylinder 411, the inner sidewall of which abuts against the outer sidewalls of the first sidewall 110, the bent portion 120, and the second sidewall 130. The lower three-punch die 420 includes a lower three-punch die core 421, the outer sidewall of which abuts against the inner sidewalls of the first sidewall 110, the bent portion 120, and the second sidewall 130. The upper three-punch die 410 is a movable die that can be raised and lowered, while the lower three-punch die 420 is a fixed die that remains stationary.
[0055] The upper three-punch die 410 and the lower three-punch die 420 are initially in the open state. The cup product 100, processed by the two-punch die 300, is placed on the lower three-punch die 420, with the lower three-punch die core 421 inserted into the inner cavity 140 of the cup product 100. Then, the upper three-punch die 410 is pressed down to close the mold. The inner side wall of the upper three-punch die cylinder 411, together with the outer side wall of the lower three-punch die core 421, shapes the first side wall 110, the bent portion 120, and the second side wall 130 of the cup product 100. In this way, the basic appearance of the cup product 100 is basically completed.
[0056] In some embodiments of this utility model, reference is made to Figure 10 , Figure 11 The upper die cylinder 411 of the three punches includes, in sequence, a first section 4111 of the upper die cylinder, a second section 4112 of the upper die cylinder, and a third section 4113 of the upper die cylinder. The lower die core 421 of the three punches includes, in sequence, a first section 4211 of the lower die core, a second section 4212 of the lower die core, and a third section 4213 of the lower die core. The first section 4111 of the upper die cylinder and the first section 4211 of the lower die core clamp the first side wall 110. The second section 4112 of the upper die cylinder and the second section 4212 of the lower die core clamp the bent part 120. The third section 4113 of the upper die cylinder and the third section 4213 of the lower die core clamp the second side wall 130. In this way, the upper three-punch die 410 is pressed down to close the mold, and the positions of the first section 4111, the second section 4112, and the third section 4113 of the upper three-punch die cylinder on the inner side wall of the upper three-punch die cylinder 411 can correspond to the first section 4211, the second section 4212, and the third section 4213 of the lower three-punch die core on the outer side wall of the lower three-punch die core 421, ensuring that the forming effect of the first side wall 110, the bent part 120, and the second side wall 130 of the cup product 100 is sufficiently accurate.
[0057] In a further embodiment of this utility model, a three-punch lower die core 421 is fitted with a three-punch lower die outer sleeve 422. The upper side of the three-punch lower die outer sleeve 422 can abut against the lower side of the opening bending edge 160 to stabilize the position of the opening bending edge 160 and ensure that the cup product 100 does not shift. The three-punch lower die outer sleeve 422 can move up and down to cooperate with the above-mentioned mold closing steps.
[0058] In some embodiments of this utility model, a three-punch upper mold plate 412 is provided inside the three-punch upper mold cylinder 411. When the three-punch upper mold 410 is pressed down to close the mold, the three-punch upper mold plate 412 and the three-punch lower mold core 421 press against the bottom wall 150 position to ensure the forming effect of the bottom wall 150 position.
[0059] In some embodiments of this utility model, reference is made to Figure 2 , Figure 7 The high-cylinder cup stamping device of this utility model also includes a four-punch die 500, which is used to roll the open bending edge 160 into a circle. The four-punch die 500 includes a four-punch upper die 510 and a four-punch lower die 520. The four-punch upper die 510 has a four-punch upper die cavity 511, which can hold the outer wall of the cup product 100. The four-punch lower die 520 is provided with an annular rolling groove 521 on its upper side, which can roll the open bending edge 160 of the cup product 100 into a circle. The four-punch upper die 510 is a movable die that can be raised and lowered, while the four-punch lower die 520 is a fixed die that remains stationary.
[0060] The upper four-punch die 510 and the lower four-punch die 520 are initially in the open state. The cup product 100, processed by the three-punch die 400, is placed on the lower four-punch die 520, with the opening bent edge 160 of the cup product 100 corresponding to the annular rolling groove 521 of the lower four-punch die 520.
