Abstract
Description
Technical Field
[0001] This utility model specifically relates to a multi-station punch press for high-speed manufacturing of can-shaped products, belonging to the technical field of can-making equipment. Background Technology
[0002] In the metal packaging container manufacturing industry, optimizing the can-making process is crucial for production efficiency and cost control. Currently, traditional metal can-making processes often rely on multiple stretching machines working in tandem to complete can forming. This production model suffers from high equipment investment costs, large floor space requirements, and complex equipment maintenance. With increasingly fierce industry competition, companies are demanding higher levels of economic efficiency and effectiveness in can-making processes.
[0003] The DWI (Drawn Wall Ironing) forming process has emerged, bringing a new solution to the metal can manufacturing industry. DWI breaks away from the traditional model of relying on multiple stretching machines, instead using multiple machines to complete the can production. Currently, DWI plays a vital role in the production of packaging products such as beverage cans and food cans due to its advantages of high production efficiency, good can-making precision, and high material utilization. However, when it comes to manufacturing metal cans with small diameters (especially less than 40mm) and high heights, the existing DWI process has significant drawbacks. Because forming small-diameter, high-height cans is difficult, a single stretching machine cannot meet the forming requirements, often necessitating the use of multiple stretching machines and multiple processes to complete the can-making process. This not only significantly increases equipment investment costs but also complicates the production process, increases production management difficulty and time costs, and reduces overall production efficiency.

[0033] In view of the shortcomings of the prior art, the inventors of this case, through long-term research and extensive practice, have proposed the technical solution of this utility model. The following will further explain and illustrate the technical solution, its implementation process and principle in conjunction with the accompanying drawings and specific implementation examples. Unless otherwise specified, the motor, crankshaft, conveyor line, punch press bed, etc. involved in this utility model are all known in the art and can be obtained by commercial purchase or conventional processing known in the art, and are not specifically limited here.
[0034] In a typical implementation case, please refer to Figure 1 and Figure 2 A high-speed multi-station punch press for manufacturing can-shaped products includes: a punch press bed 100 and a stamping forming module 200, a stamping power module 300, an internal conveying module 400, and a cup-pushing module 500 mounted on the punch press bed 100. The stamping forming module 200 includes five (i.e., x=5) first stretching forming dies and five second stretching forming dies. The five first stretching forming dies are respectively arranged at five first stretching stations, and the five second stretching forming dies are respectively arranged at five second stretching stations. The stamping power module 300 is connected to the five first stretching forming dies and the five second stretching forming dies via a transmission connection. It simultaneously provides power to five first stretch forming dies and five second stretch forming dies. The first stretch forming dies are used to process the blank located at the first stretching station into a first product with a first size. The second stretch forming dies are used to further process the first product located at the second stretching station into a second product with a second size. The internal conveying module 400 is used to convey the first product processed by the first stretch forming dies to the second stretch forming dies. The pusher module 500 is used to push the blank to the first stretch forming dies and push the first product from the first stretch forming dies to the internal conveying module 400.
[0035] Specifically, the press bed 100 is used to provide support and mounting foundation for other functional modules of the press. The structure of the press bed 100 is not considered an improvement of this utility model, and its specific structure is not limited here.
[0036] For details, please refer to the following document again. Figure 1 , Figure 3 , Figure 4 The stamping forming module 200 includes an upper die module 210 and a lower die module 220 arranged opposite to each other along a first direction. The upper die module 210 includes five first punch structures 212 and five second punch structures 213. The lower die module 220 includes five first die structures 222 and five second die structures 223. Each first punch structure 212 corresponds to and matches a first groove structure to form a first stretching forming die, and each second punch structure 213 corresponds to and matches a second groove structure to form a second stretching forming die. The lower die module 220 is fixed on the press bed 100, and the upper die module 210 is movably configured with the press bed 100. The upper die module 210 is driven by the stamping power module 300 and can move closer to or further away from the lower die module 220 along the first direction under the drive of the stamping power module 300, so that the five first stretching forming dies and the five second stretching forming dies can simultaneously realize the stamping and stretching forming of the first product and the second product. It can be understood that the first direction can be a vertical direction.
[0037] Please refer to the following for details. Figure 1 and Figure 3 To enable the five first punch structures 212 and five second punch structures 213 to be driven synchronously, the upper die module 210 also includes an upper die base 211, on which the five first punch structures 212 and five second punch structures 213 are mounted. In a typical implementation, the five first punch structures 212 and five second punch structures 213 are fixedly mounted on the upper die base 211, and the overall structure formed by the five first punch structures 212, five second punch structures 213, and the upper die base 211 can move synchronously. In this scheme, the stamping power module 300 can be connected only to the upper die base 211 for transmission. By directly driving the upper die base 211 to move up and down along the first direction, the five first punch structures 212 and five second punch structures 213 can move synchronously up and down along the first direction, achieving synchronous stretching and forming of the first and second products. In this scheme, the stamping power module 300 only needs to be a power module capable of linear drive, such as a linear drive motor / cylinder.
[0038] As another implementation method, and also a preferred embodiment of this utility model, please refer to [link / reference]. Figure 3The first punch structure 212 and the second punch structure 213 are mounted on the upper die base 211 and are movable with the upper die base 211 in the first direction. All five first punch structures 212, five second punch structures 213, and the upper die base 211 are connected to the stamping power module 300 and are driven by the stamping power module 300 to move up and down along the first direction. It should be noted that the first punch structures 212 and second punch structures 213 can only move relative to the upper die base 211 in the first direction; they are relatively fixed in other directions. In this design, the upper mold module 210 further includes five first pressing structures 214 and five second pressing structures 215. The first pressing structures 214 and the second pressing structures 215 are fixedly mounted on the upper mold base 211. Each first pressing structure 214 is sleeved around a first punch structure 212, and the first pressing structure 214 is movably engaged with the first punch structure 212. Each second pressing structure 215 is sleeved around a second punch structure 213, and the second pressing structure 215 is movably engaged with the second punch structure 213. As a preferred embodiment, a first punch structure 212 is coaxially arranged with a first pressing structure 214 sleeved around its own periphery, and a second punch structure 213 is coaxially arranged with a second pressing structure 215 sleeved around its own periphery. When the upper die module 210 is driven to move downward along the first direction towards the lower die module 220, the first blank holder structure 214 / second blank holder structure 215 will maintain contact with the blank / first product and apply pressure to it (this pressure also comes from the stamping power module 300 and the weight of the upper die module 210, etc.), thereby fixing and restricting the blank / first product. Then, the first punch structure 212 / second punch structure 213 is driven to continue moving downward along the first direction, thereby cooperating with the first die structure 222 / second die structure 223 to realize the stamping and drawing process of the first product / second product.
[0039] It should be noted that the first punch structure 212 can be the first punch, and the second punch structure 213 can be the second punch. The shape and size of the first punch match the first product, and the shape and size of the second punch match the second product. The specific structure of the punch is not limited here. The first pressing structure 214 and the second pressing structure 215 are cylindrical structures in general. Their specific structure and size can be set according to specific circumstances, and no specific limitation is made here.
[0040] Specifically, to match the scheme of movable cooperation between the first punch structure 212, the second punch structure 213, and the upper die base 211 in the first direction, the structure of the stamping power module 300 can be any known in the art. For example, the stamping power module 300 may include a drive mechanism, a crankshaft 310, a connecting rod 320, etc. The drive mechanism is drively connected to the crankshaft 310, the crankshaft 310 is rotatably connected to the connecting rod 320, and the connecting rod 320 is also connected to the first punch structure 212 and the second punch structure 213. It is understood that in the first direction, the stroke distance of the upper die base 211 is equal to the stroke distance of the first punch structure 212 and the second punch structure 213. The first blank holder structure 214 / second blank holder structure 215 maintains contact with the blank / first product. The stroke distance of the first punch structure 212 and the second punch structure 213 is set according to the specifications and size requirements of the first and second products to be processed. For example, the first driving mechanism may be a rotary drive motor, etc., and the first pressing structure 214 / second pressing structure 215 may be a cylinder or the piston part of a cylinder.
[0041] For details, please refer to the following document again. Figure 4 The lower die module 220 may also include a lower die base 221, which can be fixedly mounted on the press bed 100. Five first die cavities 222 and five second die cavities 223 are fixedly mounted on the lower die base 221. Understandably, the layout of the five first die cavities 222 and five second die cavities 223 is the same as and corresponds one-to-one with the layout of the five first punches 212 and five second punches 213. For details, please refer to [the relevant documentation / reference]. Figure 3 and Figure 4 Five first punch structures 212 and five second punch structures 213 are arranged sequentially along the second direction. One first punch structure 212 and one second punch structure 213 are corresponding and spaced apart along the third direction. Five first die structures 222 and five second die structures 223 are arranged sequentially along the second direction. One first die structure 222 and one second die structure 223 are corresponding and spaced apart along the third direction. The second direction and the third direction are located in the same plane and intersect each other. The plane where the first direction, the second direction, and the third direction are located intersects. The plane where the second direction and the third direction are located can be a horizontal plane.
[0042] Specifically, to restrict the stamping motion trajectory of the upper die module 210 and the lower die module 220, the stamping forming module 200 also includes multiple guide structures, which are disposed on the upper die module 210 and the lower die module 220. Specifically, each guide structure includes a guide post 216 and a guide hole 226. One of the guide post 216 and the guide hole 226 is disposed on the upper die base 211, and the other is disposed on the lower die base 221. Each guide post 216 corresponds to a guide hole 226, and the guide hole 226 is located on the motion trajectory of the guide post 216. Furthermore, the diameter of the guide hole 226 is slightly larger than the diameter of the guide post 216. When the upper die module 210 and the lower die module 220 approach each other along the first direction, the guide post 216 is inserted into the guide hole 226, which allows the upper die module 210 to remain moving along the first direction without radial movement. Preferably, the stamping module 200 may include four guide structures, which are respectively disposed at the four corners of the upper die base 211 / lower die base 221. More specifically, springs may also be provided on the guide post 216 or in the guide hole 226 as a buffer structure to reduce the rigid impact between the upper die module 210 and the lower die module 220.
[0043] For details, please refer to the following document again. Figure 1 The internal conveying module 400 includes five internal conveying lines 410. Each internal conveying line 410 corresponds to a first stretching mold and a second stretching mold, and is used to convey the first product to the second stretching mold. The cup-pushing module 500 is used to push the blank to the first stretching mold and push the first product from the first stretching mold to the internal conveying line 410. More specifically, the two ends of each internal conveying line 410 are located at a first station and a second station, respectively. More specifically, the two ends of each internal conveying line 410 are connected to a first die structure 222 and a second die structure 223, respectively. The cup-pushing module 500 is used to push the blank to the first die structure 222. Specifically, the structural composition of the conveyor line is known in the art. For example, the internal conveyor line 410 may include sprockets or pulleys, a motor, and a conveyor chain or belt. The motor is driven by the sprockets or pulleys, and the conveyor chain or belt is driven by the sprockets or pulleys. Products that fall onto the conveyor chain or belt can travel along with the conveyor chain or belt. These are all conventional structures known in the art and will not be described in detail here. Specifically, the internal conveyor line 410 includes a first conveyor segment and a second conveyor segment. The first and second conveyor segments are smoothly connected. One end of the first conveyor segment is connected to or connected to the first die structure 222, and one end of the second conveyor segment is connected to or connected to the second die structure 223. Both the first and second conveyor segments are inclined relative to the horizontal plane, and their inclination directions are opposite, thereby realizing the transfer of products from the first die structure 222 side to the second die structure 223 side.
[0044] For details, please refer to the following document again. Figure 4 In order to ensure that the blank / first product can accurately enter the first die structure 222 / second die structure 223, the lower die module 220 also includes five first guide structures 224 and five second guide structures 225. The first guide structures 224 and the second guide structures 225 are fixedly disposed on the lower die base 221. Each first guide structure 224 is disposed on the upstream side of a first die structure 222 along the blank conveying direction and is used to guide the blank to the first groove structure. Each second guide structure 225 is disposed on the upstream side of a second die structure 223 along the first product conveying direction and is used to guide the first product to the second groove structure. Specifically, the first guide structure 224 has a first guide channel through which the blank can pass, or the first guide structure 224 and the lower mold base 221 enclose a first guide channel through which the blank can pass. The second guide structure 225 has a second guide channel through which the first product can pass, or the second guide structure 225 and the lower mold base 221 enclose a second guide channel through which the first product can pass. It can be understood that the end outlet of the first guide channel is the first station, and the end outlet of the second guide channel is the second station.
[0045] For details, please refer to Figure 5 The pusher module 500 includes a second drive mechanism and five push rods. Each of the five push rods corresponds one-to-one with one of the five first die structures 222. The push rods are positioned upstream of the first die structures 222 along the material conveying direction. The second drive mechanism is connected to the five push rods and drives them to reciprocate. The material located upstream of the first die structures 222 lies on the movement trajectory of the push rods. For example, the second drive mechanism can be a linear drive motor or a cylinder, etc., and the structure of the push rods is not limited here.
[0046] For details, please refer to the following document again. Figure 1 The multi-station punch press for high-speed manufacturing of can-shaped products also includes a product export module 600, which is used to export the second product. Specifically, the product export module includes five product output lines or five product export channels, which correspond to five second die structures 223 respectively. The second product formed by punching and drawing by the second punch structure 213 and the second die structure 223 can directly fall into a product output line or product export channel and be exported. Of course, the second product can also be pushed into the product output line or product export channel by other means. It should be noted that the structure of the product output line / product export channel can be known in the art and is not specifically limited here.
[0047] The present invention provides a multi-station punch press for high-speed manufacturing of can-shaped products, which performs a product stamping and drawing process including: five blanks (when the product is a battery case, the blanks are cups) are pushed by a reciprocating cup-pushing module 500. The blanks enter the entrance of the first die structure 222 via the first guide structure 224. The crankshaft 310 is driven to rotate, driving the connecting rod and the upper die module 210 to move downward in the first direction. The first pressing structure 214 first contacts and presses the blank. The crankshaft 310 continues to rotate, driving the first punch structure 212 to move downward and causing the blank to pass through the first die structure 222 to form the first product; the first product reaches the lower dead center. After the die is removed, it moves upward to complete demolding, and the first pressing structure 214 moves upward and resets. The first product is pushed to the internal conveyor line 410 by the cup pusher module 500. The internal conveyor line 410 transports the first product to the second guide structure 225, which then enters the entrance of the second die structure 223. While the first punch structure 212 punches and pulls the blank, the second punch structure 213 works with the second die structure 223 to punch and pull the first product to form the second product. The second product is then conveyed to the external conveyor line or downstream equipment through the product export module. This method can achieve simultaneous operation of ten dies and cannulation through five channels, enabling high-speed production. It should be noted that the second product is a can-shaped product, such as a battery casing.
[0048] This utility model provides a multi-station punch press for high-speed manufacturing of can-shaped products. The structure is more compact, which can reduce the can-making process. It can achieve material discharge while making cans, and then realize the simultaneous high-speed multi-station production of cans of two processes through the internal conveying module, thereby improving the can-making efficiency.
[0049] It should be understood that the above embodiments are merely illustrative of the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
