Description

Technical Field

[0001] This application belongs to the field of aluminum-plastic film stamping equipment, and more specifically, relates to a stamping device that facilitates mold replacement. Background Technology

[0002] In the production process of pouch batteries, after the tabs are welded to the cell, workers need to place the cell in an aluminum-plastic film that has undergone the casing process. After folding and heat sealing, the battery manufacturing is completed. Current technology typically uses a casing-forming device to press the aluminum-plastic film to create the aluminum-plastic casing.

[0003] For example, a stamping device includes a lower plate fixedly mounted on the top surface of a worktable. A mold is detachably mounted on the side of the lower plate away from the worktable, and a stamping head is mounted on the side of the mold away from the lower plate. The stamping head slides towards or away from the mold. During the stamping process, the stamping head cooperates with the mold to apply force to the aluminum-plastic film, thus completing the stamping process quickly and easily. To facilitate mold replacement, a sliding roller and a limiting block are provided on the side of the lower plate facing the mold. The top surface of the sliding roller protrudes from the surface of the lower plate, and the limiting block is located on the top surface of the lower plate, abutting against the side wall of the mold to limit its movement. When changing the mold, the limiting block is removed, the mold is pushed, and the mold slides out under the action of the sliding roller.

[0004] However, during use, it was found that the sliding rollers experienced some wear under pressure during the stamping process, which affected the service life of the device. Utility Model Content

[0005] The technical problem to be solved by this application is to overcome the shortcomings of the prior art and provide a stamping device that facilitates mold replacement.

[0006] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted in this application is as follows:

[0007] A stamping device for easy mold replacement includes a stamping assembly. The stamping assembly includes a stamping head for stamping, a mold for defining the stamping shape, and a lower plate for mounting the mold. The lower plate is disposed on the side of the mold away from the stamping head. The lower plate has a through-hole. A first abutment is disposed on the side of the lower plate away from the mold. The lower plate is slidably disposed relative to the first abutment in a direction toward or away from the first abutment. The first abutment has a state in which it passes through and protrudes from the sidewall of the through-hole and abuts against the mold.

[0008] Preferably, it further includes a second abutment, which is flush with the first abutment in the horizontal direction, and the second abutment is disposed on one side of the lower plate when the first abutment is in contact with the mold.

[0009] Preferably, both the first abutting member and the second abutting member are configured as abutting posts.

[0010] Preferably, the first abutting member and / or the second abutting member further includes a roller, which is rotatably disposed on the side of the first abutting post or the second abutting post near the stamping head.

[0011] Preferably, the mold is provided with a sliding rail on the side facing the lower plate, and both the first abutting member and the second abutting member slide in cooperation with the sliding rail.

[0012] Preferably, the second abutment is plate-shaped, and the first abutment and the second abutment are arranged on the same straight line along the length of the second abutment.

[0013] Preferably, it also includes a limiting member, which is fixedly, slidably, or detachably disposed on the side of the lower plate facing the mold. When the limiting member is fixedly or slidably disposed on the lower plate, the limiting member is disposed below the first abutment member.

[0014] Preferably, the lower plate has support points that provide support and drive to the lower plate, and the first abutment is disposed on the line connecting the two support points.

[0015] Preferably, the stamping assembly further includes an upper plate for mounting a stamping head, the upper plate being disposed on the side of the mold away from the lower plate, and the side of the upper plate facing the lower plate being provided with a first mounting rod for mounting the upper plate, the first mounting rod being offset from the lower plate.

[0016] Preferably, a connecting rod is provided on the side of the stamping head away from the mold, and a mounting rail is detachably provided on the side of the upper plate away from the mold at intervals. The connecting rod passes through the upper plate and slides with the mounting rail; the connecting rod and the mounting rail are detachably provided.

[0017] By adopting the above technical solution, this application has the following beneficial effects compared with the prior art.

[0018] By setting a first abutment and corresponding clearance holes on the lower plate, and sliding the lower plate relative to the first abutment, when the mold needs to be replaced, the operator must first slide the lower plate toward the first abutment. During the sliding process, the first abutment extends into the clearance hole and abuts against the mold. At this point, continuing to move the lower plate causes the first abutment to lift the mold, separating the mold from the lower plate, facilitating the smooth removal of the mold. After replacement, the operator slides the lower plate again, raising it to separate the mold from the first abutment and bring it into contact with the lower plate. This effectively reduces the impact of the stamping process on the first abutment, thereby improving the lifespan of the device.

[0019] Furthermore, by setting up sliding rollers, the resistance during mold installation or removal is effectively reduced, improving work efficiency; in addition, the sliding rails can also limit the mold, effectively reducing the occurrence of mold misalignment. Attached Figure Description

[0028] In the description of this application, the installation of parts can be carried out using conventional installation and locking methods used in the prior art, such as bolt connection, snap locking, and chain locking. In the embodiments of this application, only bolt connection is described as an example.

[0029] The specific embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0030] A stamping device that facilitates mold replacement, as shown in the reference. Figure 1 and Figure 2 The system includes a worktable 1 and a stamping assembly 2. The stamping assembly 2 includes an upper plate 201 suspended above the top of the worktable 1, a stamping head 203 slidably disposed on the side of the upper plate 201 facing the worktable 1, a mold 205 slidably disposed on the side of the stamping head 203 away from the upper plate 201, and a lower plate 207 for detachably mounting the mold 205. The stamping head 203 and the mold 205 both slide in a direction toward or away from the worktable 1. The upper plate 201 is fixed relative to the worktable 1, and the lower plate 207 is slidably disposed relative to the worktable 1 and the upper plate 201.

[0031] Reference Figure 1 A first drive motor 209 is bolted to the workbench 1. The drive end of the first drive motor 209 passes through and extends out of the top surface of the workbench 1, and connects to the support point set on the lower plate 207 to support or drive the lower plate 207 to slide. In actual installation and use, the number and position of the first drive motor 209 can be set according to the actual situation. In this embodiment, one first drive motor 209 is provided. The first drive motor 209 drives the lower plate 207 through a threaded rod, and the drive end of the threaded rod is connected to the center position of the lower plate 207. In order to ensure the stability of the lower plate 207 during the sliding process and the stamping process, four limiting rods 210 are also distributed at the four corners of the lower plate 207. The end of the limiting rod 210 away from the lower plate 207 is slidably connected to the workbench 1.

[0032] Reference Figure 1 and Figure 3The top surface of the workbench 1 is also provided with a first abutment 3. In this embodiment, the first abutment 3 is columnar and is located on the line connecting the limiting rod 210 and the threaded rod. In other embodiments, the first abutment 3 can also be set with different shapes and positions according to the actual load-bearing conditions. The lower plate 207 is provided with a clearance hole 208 corresponding to the position of the first abutment 3. The clearance hole 208 is provided through the lower plate 207 and abuts against the lower plate 207 when the mold 205 is in use, thus sealing the opening of the clearance hole 208.

[0033] When mold 205 is not installed, the first abutment 3 passes through the clearance hole 208 and protrudes from the side wall of the clearance hole 208. When installing mold 205, the trolley transports mold 205 to the side of the first abutment 3 away from the worktable 1. The first abutment 3 supports mold 205 on the side of the lower plate 207 away from the worktable. Then, the lower plate 207 is slid to contact mold 205, further separating mold 205 from the first abutment 3, thus completing the installation of mold 205. When changing mold 205, continuously lowering the lower plate 207 separates mold 205 from the lower plate 207, which is convenient and quick.

[0034] Reference Figure 1 and Figure 3 A limiting member 211 is fixedly provided on the side of the lower plate 207 facing the mold 205. When the mold 205 is not installed, the limiting member 211 is set lower than the first abutting member 3. During the sliding of the lower plate 207, the limiting member 211 slides with the lower plate 207, limiting the mold 205 or separating from the mold 205. In this embodiment, the limiting member 211 is rod-shaped. In other embodiments, the limiting member 211 can also be plate-shaped, and the limiting member 211 is inserted into the surface of the lower plate 207 by opening an insertion hole.

[0035] Reference Figure 3 A second abutment 4 is also provided on the side of the workbench 1 facing the lower plate 207. The side wall of the second abutment 4 facing the mold 205 is flush with the side wall of the first abutment 3 and is located on one side of the lower plate 207. In this embodiment, the second abutment 4 is plate-shaped, and the first abutment 3 is located on the extension line of the second abutment 4 along its length. In other embodiments, the second abutment 4 may also be formed by an array of multiple spaced abutment columns.

[0036] In other embodiments, to facilitate the movement of the mold 205 along the surfaces of the first abutment 3 and the second abutment 4, rollers can be rotatably mounted on the sidewalls of the first abutment 3 and the second abutment 4 facing the mold 205. After the mold 205 separates from the lower plate 207, the operator can move the mold 205 out of the area of ​​the lower plate 207 by pushing the mold 205. The second abutment 4 has a receiving and guiding function for the mold 205 sliding along the surface of the first abutment 3, effectively reducing the possibility of the mold 205 falling between the moving trolley and the first abutment 3, making the movement of the mold 205 more stable, and reducing the possibility of damage to the mold 205.

[0037] Reference Figure 3 To reduce the workload of correcting the mold 205 during installation, a grooved sliding rail 206 is provided on the side of the mold 205 facing the lower plate 207. The sliding rail 206 slides and engages with the first abutment 3 and the second abutment 4. Both ends of the sliding rail 206 penetrate the side wall of the mold 205. During the process of moving the mold 205 into the lower plate 207, the ends of the first abutment 3 and the second abutment 4 near the mold 205 extend into the sliding rail 206 and engage with the side wall of the sliding rail 206 to limit the movement of the mold 205.

[0038] Reference Figure 1 A first mounting rod 5 is also installed on the workbench 1. The end of the first mounting rod 5 away from the workbench 1 is connected to the upper plate 201, which protrudes from the side wall of the lower plate 207. This arrangement makes the mounting rod and the lower plate 207 staggered, effectively increasing the space for installing and replacing the mold 205. A second mounting rod 6 is installed on the side of the upper plate 201 away from the mold 205. The end of the second mounting rod 6 away from the upper plate 201 is connected to a first mounting plate 7. The side of the first mounting plate 7 away from the upper plate 201 is suspended by a third mounting rod 8, and a second drive motor 10 is installed on the side of the second mounting plate 9 away from the first mounting plate. The drive end of the second drive motor 10 passes through the second mounting plate 9 and is connected to the coupling 11 located between the first mounting plate 7 and the second mounting plate 9.

[0039] Reference Figure 1One end of the coupling 11, away from the second drive motor 10, passes through the first mounting plate 7 and is connected to a screw rotatably mounted on the side of the first mounting plate 7 facing the upper plate 201. A screw seat 12 is connected to the side of the screw away from the first mounting plate 7, and the screw seat 12 is slidably mounted relative to the screw. A third mounting plate 13 is fixedly mounted on the side of the screw seat 12 away from the screw, and a second mounting rod 6 passes through the third mounting plate 13, and the third mounting plate 13 is slidably mounted along the second mounting rod 6. During use, the screw is driven to rotate by the second drive motor 10, thereby causing the screw seat 12 to slide along the third mounting plate 13. In addition, to further limit the stability of the sliding process of the third mounting plate 13, a sliding rod 14 is also slidably mounted through the third mounting plate 13. One end of the sliding rod 14 is connected to the upper plate 201, and the other end is provided with a baffle to prevent the third mounting plate 13 from separating from the sliding rod 14.

[0040] Reference Figure 1-4 The third mounting plate 13 is also detachably equipped with a mounting rail 15 on the side facing the mold 205. The mounting rail 15 has open ends, and a connecting rod 16 is slidably fitted inside the mounting rail 15. Correspondingly, the upper plate 201 has a through hole 202 at the position of the connecting rod 16, through which the connecting rod 16 passes and is connected to the punch head 203. The stamping assembly 2 also includes a punch limiting plate 204 for accommodating the punch head 203. The punch limiting plate 204 is bolted to the side of the upper plate 201 away from the third mounting plate 13. To facilitate the disassembly of the punch head 203, the bolts are located on the side of the upper plate 201 away from the punch head 203.

[0041] When the mold 205 is not installed, the punch head 203 and the punch limit plate 204 are flush with the side wall facing the mold 205. During use, the lower plate 207 is slid to make the mold 205 abut against the side wall of the punch limit plate 204. Then the second drive motor 10 is started, and the second drive motor 10 drives the threaded rod to rotate, which moves the screw seat 12, thereby driving the third mounting plate 13, the mounting rail 15 and the connecting rod 16 to slide, thereby pushing the punch head 203 to slide and complete the punching operation.

[0042] After removing and replacing the corresponding mold 205, the operator can slide the lower plate 207 until it abuts against the punch limiter 211. Then, remove the mounting rail 15 and slide it to separate the connecting rod 16 from the mounting rail 15. Remove the bolts connecting the punch limiter 211 to the upper plate 201. At this point, move the lower plate 207 down. The punch head 203, punch limiter 204, and connecting rod 16 will all slide with the lower plate 207 and separate from the upper plate 201. Repeat the mold 205 removal operation to complete the removal of the punch head 203.

[0043] The principle of this embodiment is that the upper plate 201 of the stamping head 203 is fixedly installed, and the lower plate 207 is slidably installed. By opening a clearance hole 208 on the lower plate 207 and correspondingly setting the first abutment 3, during the sliding process, the first abutment 3 lifts the mold 205 and the stamping head 203 set on the top of the lower plate 207, realizing the separation of the mold 205 and the stamping head 203, which facilitates the replacement of the mold 205 and the stamping head 203, making it convenient and quick.
