A cutting fixture for producing aluminum casings for new energy batteries

Abstract

This invention relates to the technical field of battery aluminum shell production, specifically a cutting fixture for producing aluminum shells for new energy batteries. It includes a worktable, a feeding mechanism, a cutting component, a clamping mechanism, a pressing mechanism, a collecting assembly, and an internal support mechanism. The pressing mechanisms on both sides of the cutting edge of the battery aluminum shell press against the upper end of the shell while simultaneously driving the clamping mechanism to complete the partitioned clamping operation of multiple sets of battery aluminum shells. This ensures that the battery aluminum shells on both sides remain vertical during the cutting process. The product uses a partitioned clamping combined with end-push method to avoid excessive clamping of battery aluminum shells at once, which could lead to displacement deviation of the product in the middle during feeding. This ensures that the displacement of multiple battery aluminum shells remains consistent after each cut, guaranteeing the neatness of the cut and increasing the product qualification rate. The internal support mechanism extends near the cutting edge of the battery aluminum shell to support the inner wall of the shell, reducing the problem of warping and deformation of the cut edge caused by excessive cutting force during the cutting process.

Description

Technical Field

[0001] This invention relates to the technical field of aluminum battery casing production, specifically a cutting tooling for producing aluminum casings for new energy batteries. Background Technology

[0002] A battery aluminum casing refers to a battery casing made of aluminum alloy material. It is mainly used to encapsulate various types of batteries such as lithium-ion batteries and nickel-metal hydride batteries, and plays a role in protecting the internal cells, isolating them from the external environment, supporting the battery structure, and assisting in heat dissipation.

[0003] The aluminum battery casing is a thin-walled rectangular shell structure with a length and height greater than its width. During cutting, multiple casings are typically arranged together and clamped on both sides. The cutting blade moves from back to front, cutting the casings sequentially. However, this cutting process presents the following problems: 1. Several battery casings arranged together are only fixed on one side of the cutting point. During cutting, due to the thin-walled structure and the tendency of already cut casings to collapse, the uncut casings, lacking rear-side restraint, are more prone to deformation under stress. Furthermore, when multiple casings are clamped towards the cutting point, the casing in the middle may experience displacement errors due to insufficient clamping force. If the ends are not aligned, dimensional deviations may occur between the finished products. 2. The cutting process generates a large amount of debris, which adheres to the inner and outer walls of the cutting area and the operating platform. This not only pollutes the working environment requiring regular cleaning but also makes subsequent battery casings unevenly placed. Summary of the Invention

[0004] This invention provides a cutting fixture for the production of aluminum casings for new energy batteries, in order to solve problems in the cutting process of aluminum casings for batteries in related technologies.

[0005] This invention provides a cutting fixture for producing aluminum shells for new energy batteries, including a worktable, a feeding mechanism located on the left side of the upper part of the worktable, and a cutting component located in the middle of the worktable. An inverted U-shaped plate is provided on the upper part of the worktable, and the cutting component is slidably mounted on the inverted U-shaped plate. The cutting component consists of a rotating blade and a protective cover, and also includes an elastic anti-chip cover fixedly located at the lower part of the protective cover; a clamping mechanism symmetrically located on both sides of the elastic anti-chip cover for clamping the cut area of ​​the battery aluminum shell; two sets of clamping mechanisms, located on opposite sides of the two clamping mechanisms, clamping multiple battery aluminum shells in sections with the cooperation of the clamping mechanisms; the clamping mechanism includes a fixed rod detachably connected to the vertical section of the inverted U-shaped plate, with two limiting plates symmetrically arranged on the fixed rod, and at least one adaptive adjustment component between the two limiting plates to separate and limit the battery aluminum shells; a pushing component above the adaptive adjustment component for use with the clamping mechanism, the pushing component moving downwards to allow the adaptive adjustment component and the limiting plates to clamp multiple sets of battery aluminum shells in sections.

[0006] The cutting fixture also includes a collection component and an inner support mechanism located at the right end of the worktable. When the battery aluminum shell is fed to the right, the inner support mechanism adaptively provides inner support to the right side of the battery aluminum shell.

[0007] In one possible implementation, the clamping mechanism includes a fixed plate fixedly connected between two vertical sections of the inverted U-shaped plate, a movable plate connected to the fixed plate via a telescopic cylinder, and a clamping plate fixedly connected to the bottom end of the movable plate via a connecting rod; the clamping plate is fixedly connected to an elastic chip shield.

[0008] In one possible implementation, the adaptive adjustment component includes a rectangular block detachably connected to a fixed rod, a through hole extending from front to back in the rectangular block, two symmetrical protrusions sliding elastically within the through hole, a clearance hole communicating with the through hole at the upper end of the rectangular block, a pressing block elastically slidably connected within the clearance hole and cooperating with the protrusions, and the pressing block, when subjected to downward pressure from the pushing component, presses the two protrusions out of the through hole.

[0009] In one possible implementation, the pushing assembly includes an ear fixedly connected to the left side of the movable plate, a through hole in the ear, a limit rod elastically slidably connected within the through hole, and a pushing strip fixedly connected to the bottom end of the limit rod, the pushing strip being located directly above the extrusion block.

[0010] In one possible implementation, the collection assembly further includes a collection compartment on the workbench; a pull-out drawer with an upward opening is slidably disposed inside the collection compartment, a vacuum cleaner is installed on the front side of the workbench and corresponds to the pull-out drawer, and two sets of rectangular plates are fixed at the upper end of the workbench and at the opening of the collection compartment, each set consisting of two rectangular plates, one in front and one in back, and a rotating plate is hinged between the two rectangular plates by a torsion spring, and the gap between the two rotating plates in the horizontal state is greater than the blade thickness.

[0011] In one possible implementation, the upper end of the workbench is provided with two horizontal plates, and there is a gap between the two horizontal plates and directly below the cutting workpiece. Each of the two horizontal plates has a symmetrical circular hole near the gap, and a push rod slides elastically inside the circular hole. The bottom end of the protective cover is symmetrically and fixedly connected with a mating pressure rod that engages with the push rod.

[0012] In one possible implementation, the internal support mechanism includes a sliding block that is slidably connected to a horizontal plate; multiple sets of rectangular alignment blocks are slidably connected to the left side of the sliding block, and multiple rectangular through holes are evenly opened on the front and back of the rectangular alignment blocks. Rectangular guide blocks are symmetrically fixedly connected to the rectangular through holes. A groove is opened on the side of the sliding block near the rectangular alignment block, and an internal support module is detachably connected to the groove.

[0013] In one possible implementation, the inner support module includes a rectangular seat fixedly connected in the groove; the left side of the rectangular seat is hinged to a rectangular through hole with multiple sets of inner support bars, each set of inner support bars including two inner support bars arranged symmetrically above and below, and each set of inner support bars gradually approaches each other from left to right.

[0014] In one possible implementation, the feeding mechanism includes a T-shaped slide rail fixedly connected to the left side of the upper end of the workbench; a feeding plate slidably connected to the T-shaped slide rail via an electric slider; and a push plate that moves left and right slidably connected to the upper end of the feeding plate.

[0015] In one possible implementation, a rotating roller is rotatably connected to the upper end of the worktable, located between the feeding mechanism and the clamping mechanism, via a mounting base. The height of the rotating roller is the same as the height of the horizontal plate.

[0016] The above-mentioned one or more technical solutions in the embodiments of the present invention have at least one of the following technical effects: 1. According to the embodiments of the present invention, a cutting fixture for the production of aluminum shells for new energy batteries, through the clamping mechanism and the pressing mechanism on both sides of the cutting point of the aluminum shell, while the pressing mechanism presses the upper end of the aluminum shell, the clamping mechanism completes the partition clamping operation of multiple groups of aluminum shells, so that the aluminum shells on both sides always remain vertical during the cutting process, and when the pressing mechanism moves up to release the pressing, the clamping mechanism also automatically releases the clamping of the aluminum shell, so that the aluminum shell can be smoothly pushed by the push plate for feeding under the limit of the clamping mechanism; the aluminum shell is divided into multiple groups for clamping, and with the end pushing method, it avoids that too many products are clamped at one time, which will cause the products in the middle to have displacement deviation during feeding, and ensures that the displacement of multiple aluminum shells is consistent after each cutting, so as to ensure the neatness of the cutting edge and increase the product qualification rate.

[0017] 2. According to an embodiment of the present invention, a cutting fixture for producing aluminum shells of new energy batteries is provided. The inner support mechanism extends into the vicinity of the cutting point of the aluminum shell to support the inner wall of the aluminum shell, thereby reducing the problem of warping and deformation of the cutting edge caused by excessive cutting force during the cutting process.

[0018] 3. According to the embodiments of the present invention, a cutting fixture for the production of aluminum shells for new energy batteries is provided. The elastic anti-shaving cover makes the cutting operation in a relatively sealed environment, avoiding more debris from splashing onto the worktable. The vacuum cleaner absorbs the debris on the inner and outer walls of the aluminum shell cutting area. By cooperating with the pressure rod and the push rod, the cutting waste is automatically guided and the pull-out drawer is automatically recycled. The waste can achieve self-cleaning and continuous collection, ensuring the working environment and efficiency.

[0019] 4. The rectangular alignment block abuts the right end of the battery aluminum shell, and the pusher pushes the left end of the battery aluminum shell. This not only seals both ends of the battery aluminum shell, but also ensures that the ends of the battery aluminum shell are aligned, reducing the cutting error between the battery aluminum shells.

[0028] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0029] Please see Figure 1 and Figure 2 A cutting fixture for producing aluminum shells for new energy batteries includes a workbench 1. The upper left side of the workbench 1 is provided with a feeding mechanism 2 for pushing the aluminum shells of the batteries onto the workbench. The feeding mechanism 2 includes a T-shaped slide rail 21 fixedly connected to the upper left side of the workbench 1. A feeding plate 22 is slidably connected to the T-shaped slide rail 21 via an electric slider. A push plate 23 is slidably connected to the upper end of the feeding plate 22.

[0030] Continue reading Figure 1 , Figure 2 and Figure 3 An inverted U-shaped plate 11 is installed on the upper end of the workbench 1, to the right of the feeding mechanism 2. A cutting component 3 for cutting the aluminum battery casing is mounted on the inverted U-shaped plate 11. The cutting component 3 consists of a high-speed rotating blade and a protective cover. Through holes are provided on the side walls of the protective cover. The upper end of the protective cover is fixedly connected to the bottom end of a hydraulic telescopic rod, and the fixed section of the hydraulic telescopic rod is fixedly connected to the transverse section of the inverted U-shaped plate 11. A horizontal plate 12 is installed on the upper end of the workbench 1 via a raised plate. An elastic chip shield 4 is fixedly installed at the lower part of the protective cover. The elastic chip shield 4 is used to protect against flying debris during the cutting of the aluminum battery casing. The elastic chip shield 4 has two sides on the left and right sides... A clamping mechanism 5 is symmetrically arranged on the right side, which is used to clamp both sides of the cut part of the battery aluminum shell; a set of clamping mechanism 6 is provided on each of the opposite sides of the two clamping mechanisms 5, which is used to clamp multiple battery aluminum shells; the cutting fixture also includes an inner support mechanism 8, which is used to provide internal support for the right side of the battery aluminum shell during the cutting process; a rotating roller 13 is rotatably connected to the upper end of the worktable 1 and located between the feeding mechanism 2 and the clamping mechanism 6 through a mounting base. The height of the rotating roller 13 is the same as the height of the horizontal plate 12. The setting of the rotating roller 13 reduces the friction when the battery aluminum shell moves.

[0031] First, the battery aluminum casings are loaded. The electric slider is activated, sliding the loading plate 22 to the left side of the T-shaped slide rail 21. This facilitates the batch placement of the battery aluminum casings onto the loading plate 22. Initially, the push plate 23 is located at the far left of the loading plate 22. Multiple battery aluminum casings are placed in a group simultaneously onto the top of the loading plate 22. Each group of battery aluminum casings is slightly tilted during placement, with an angle less than 10 degrees, to facilitate subsequent clamping and correction. The sliding design of the T-shaped slide rail 21 allows for easy alignment of the battery aluminum casings with the clamping mechanism located on the left side during loading. 6. After all materials are loaded, start the electric slider to drive the loading plate 22 and the upper battery aluminum shell into the right clamping mechanism 6, completing the initial positioning of the battery aluminum shell. The left and right movement of the push plate 23 can be driven by the electric telescopic cylinder (the electric telescopic cylinder is not shown in the figure). This is existing technology and will not be described in detail here. The left and right movement of the T-shaped slide rail 21 facilitates the loading and placement of longer battery aluminum shells. The movement of the push plate 23 facilitates the intermittent movement of the battery aluminum shell towards the cutting point during the operation. With the limited length of the worktable 1, it can meet both the needs of convenient loading and operation movement.

[0032] The horizontal plate 12 is set up to ensure that the battery aluminum shells are placed at the same height, and the horizontal plate 12 located on the right side of the cutting piece 3 facilitates the placement of the cut battery aluminum shells. The cutting piece 3 performs cutting operations on multiple battery aluminum shells from top to bottom under the action of the hydraulic telescopic rod.

[0033] It should be noted that in the prior art, the number of aluminum battery casings cut at one time is around forty, and the specific number can fluctuate depending on the actual situation. The number of aluminum battery casings cut in this application is more than thirty but less than forty. While ensuring that the cutting efficiency is not significantly affected, multiple aluminum battery casings are fixed in different areas to avoid the problem of the fallen aluminum battery casings not providing auxiliary support for the uncut aluminum battery casings caused by traditional cutting methods.

[0034] See Figure 1 and Figure 3 The clamping mechanism 6 includes a fixing rod 61 detachably connected to the vertical section of the inverted U-shaped plate 11. The fixing rod 61 is symmetrically provided with two limiting plates 62 that limit the front and rear sides of the battery aluminum shell respectively. At least one adaptive adjustment member 63 is provided between the two limiting plates 62 to separate and limit multiple sets of battery aluminum shells. A pushing component 64 is provided above the adaptive adjustment member 63.

[0035] It should be noted that the number and installation position of the adaptation adjustment component 63 can be adjusted according to actual needs. In the attached drawings of this application, two adaptation adjustment components 63 are selected for installation.

[0036] Continue reading Figure 5 and Figure 6The adaptive adjustment component 63 includes a rectangular block 631 detachably connected to the fixed rod 61. The rectangular block 631 has a through hole 632 extending through its front and rear. Two symmetrical protrusions 633 slide within the through hole 632. The two protrusions 633 are connected by a spring. Multiple ball bearings (not shown in the figure) are rotatably arranged on the opposite side of the two protrusions 633 to reduce friction. The ball bearings can reduce the sliding friction between the battery aluminum shell and the protrusions 633 when pushed. The upper ends of the two protrusions 633 are provided with inclined surfaces. The upper end of the rectangular block 631 has a clearance hole 634 communicating with the through hole 632. A T-shaped pressing block 635 is slidably connected up and down within the clearance hole 634. The bottom end of the lateral end of the pressing block 635 is connected to the rectangular block 631 by a pressing spring.

[0037] It should be noted that both the limiting plate 62 and the adaptive adjustment component 63 are detachably mounted on the fixing rod 61. In actual use, the distance between the limiting plate 62 and the adaptive adjustment component 63, or between two adaptive adjustment components 63, can be adjusted according to the number of battery aluminum shells in each group. The number of adaptive adjustment components 63 can also be selected according to actual needs. The limiting plate 62 and the adaptive adjustment component 63 are fixed to the fixing rod 61 using existing fixing structures, such as bolts. When placing the battery aluminum shells, the feeding plate 22 is located at the leftmost side of the T-shaped slide rail 21, and the right side of the battery aluminum shell is located at the position of the clamping mechanism 6 on the left. Multiple battery aluminum shells are placed in a group, and the right side of the battery aluminum shell in each group is located at the position of the limiting plate 62 and the clamping mechanism 6 on the left. For ease of description, the space between the limiting plate 62 and the adapting adjustment member 63, or between two adapting adjustment members 63, is defined as the placement space. In the natural state, the distance between the two protrusions 633 is the smallest under the action of the spring, and at this time, the pressing block 635 is located at the upper end of the rectangular block 631 under the action of the pressing spring. In this state, the distance between the multiple placement spaces is the largest, which makes it easy to place multiple aluminum shells in each group. The multiple groups of battery aluminum shells are placed in the corresponding placement spaces in sequence. The feeding plate 22 is moved to the right, and the multiple groups of battery aluminum shells are moved to the right to the clamping mechanism 6 on the right side, so that the left and right sides of the cut of the battery aluminum shell are in a clamping state.

[0038] See Figure 1 , Figure 3 , Figure 4 and Figure 6The clamping mechanism 5 includes a fixed plate 51 fixedly connected between two vertical sections of the inverted U-shaped plate 11. Two telescopic cylinders 52 are fixedly connected symmetrically to the fixed plate 51. The telescopic section of the telescopic cylinder 52 slides through the bottom end of the fixed plate 51. A movable plate 53 that moves up and down is fixedly connected to the bottom end of the telescopic cylinder 52. A clamping plate 54 is fixedly connected to the right side of the bottom end of the movable plate 53 away from the telescopic cylinder 52 through a connecting rod. The side of the clamping plate 54 near the elastic anti-dandruff cover 4 is fixedly connected to the elastic anti-dandruff cover 4 through a rectangular strip.

[0039] In the initial state, the clamping plate 54 is located above the battery aluminum shell. At the same time, the telescopic cylinder 52 located on the upper side of the fixed plate 51 is activated. The telescopic cylinder 52 synchronously drives the moving plate 53 to move downward. The moving plate 53 will drive the clamping plate 54 to move downward to the upper end of the battery aluminum shell. Since the clamping plate 54 and the elastic anti-dandruff 4 are fixedly connected by a rectangular strip, the clamping plate 54 will synchronously drive the elastic anti-dandruff 4 to move downward. The bottom ends of the clamping plate 54 and the elastic anti-dandruff 4 are flush. When the clamping plate 54 is pressed down to the upper end of the battery aluminum shell, the bottom end of the elastic anti-dandruff 4 is also in contact with the upper end of the battery aluminum shell, so that both sides of the cut of the battery aluminum shell are inside the elastic anti-dandruff 4. It should be noted that the elastic anti-dandruff 4 is made of elastic material, which can be selected according to the needs during use, such as silicone rubber, metal rubber, plastic elastomer, etc.

[0040] See Figure 3 and Figure 6 The pushing component 64 includes an ear seat fixedly connected to the left side of the movable plate 53. The ear seat has a through hole that runs vertically through it. A limit rod 641 is slidably connected inside the through hole. A pushing strip 642 is fixedly connected to the bottom end of the limit rod 641. A compression spring is sleeved on the limit rod 641, and the two ends of the compression spring are fixedly connected to the ear seat and the pushing strip 642, respectively.

[0041] As the moving plate 53 moves downward, the ear seat moves downward synchronously. The limiting rod 641 on the ear seat drives the pushing strip 642 to contact the upper end of the pressing block 635 first. As the moving plate 53 continues to move downward, the pressing spring will be compressed. Under the pressure of the pushing strip 642, the pressing block 635 presses down on the protruding block 633, causing the protruding block 633 in each rectangular block 631 to move forward and backward to both sides, reducing the distance between each placement space. At this time, the tilted battery aluminum shell will gradually become perpendicular to the placement surface under the pressing action of the protruding block 633, clamping the side of each group of battery aluminum shells in sections. When the pressing spring is compressed to its shortest state, the moving plate 53 will drive the pressing plate 54 to press to the upper end of the battery aluminum shell.

[0042] See Figure 1 and Figure 7The inner support mechanism 8 includes a sliding block 81 that is slidably connected to the horizontal plate 12. Multiple sets of rectangular alignment blocks 82 are provided on the left side of the sliding block 81. The right side of the rectangular alignment block 82 is slidably connected to the sliding block 81 through a sliding rod, and the right side of the sliding rod slides through the right side of the sliding block 81. A return spring is sleeved on the sliding rod, and the two ends of the return spring are fixedly connected between the sliding block 81 and the rectangular alignment block 82 respectively.

[0043] Continue reading Figure 7 The left side wall of the rectangular alignment block 82 is evenly provided with multiple rectangular through holes from front to back. Rectangular guide blocks 83 are fixedly connected symmetrically in the rectangular through holes. The sliding block 81 is provided with a groove on the side near the rectangular alignment block 82. An inner support module is detachably connected in the groove. The inner support module includes a rectangular seat fixedly connected in the groove. Multiple sets of inner support bars 84 are hinged to the left side of the rectangular seat corresponding to the rectangular through holes. Each set of inner support bars 84 consists of two inner support bars 84 that are symmetrically distributed in the upper and lower parts. A torsion spring is provided at the connection between the inner support bar 84 and the rectangular seat. Each set of inner support bars 84 gradually approaches each other from left to right.

[0044] First, based on the multiple placement spaces formed by the limiting plate 62 and the adaptive adjustment component 63, select a matching number of inner support modules. During assembly, the rectangular base of the inner support module can be fixed into the groove on the sliding block 81 using screws. Each set of inner support bars 84 is placed into the rectangular through hole on the sliding block 81. Initially, under the limitation of the rectangular alignment block 82, the vertical distance between the two inner support bars 84 in each set is less than the inner height of the battery aluminum shell. At this time, the torsion spring connecting the inner support bars 84 is in a compressed state. During actual operation, this is achieved through external... The driving device pushes the sliding block 81 to the left to the working position. When the feeding mechanism 2 drives the battery aluminum shell to the right, the left side of the inner support bar 84 first contacts the right side of the battery aluminum shell. As the battery aluminum shell continues to move to the right, the battery aluminum shell will push the rectangular alignment block 82 to move towards the sliding block 81. Under the limiting action of the sliding block 81 and the rectangular guide block 83, the two inner support bars 84 gradually open. The left side of the inner support bar 84 gradually opens and abuts against the inner upper and lower walls of the battery aluminum shell while extending into the battery aluminum shell, thereby providing internal support for the battery aluminum shell.

[0045] See Figure 3 and Figure 6The cutting fixture for producing aluminum shells of new energy batteries also includes a collection component 7. The collection component 7 includes a collection chamber 71 set on the workbench 1. A pull-out drawer 711 with an upward opening is slidably arranged inside the collection chamber 71. A vacuum cleaner is set on the front side of the workbench 1 corresponding to the position of the pull-out drawer 711. Two sets of rectangular plates 72 are symmetrically arranged on the upper end of the workbench 1 and at the opening of the collection chamber 71. Each set of rectangular plates 72 consists of two rectangular plates 72, one in front and one in back. A rotating plate 73 is hinged between the two rectangular plates 72 by a torsion spring. When the torsion spring is not under force, the height of the rotating plate 73 is the same as that of the horizontal plate 12, and the gap between the two rotating plates 73 is greater than the thickness of the blade.

[0046] Continue reading Figure 3 and Figure 6 Two horizontal plates 12 are provided on the left and right sides. There is a gap between the two horizontal plates 12 and directly below the cutting piece 3. Each of the two horizontal plates 12 has a symmetrical circular hole near the gap. A push rod 74 is slidably installed in the circular hole. A compression spring is sleeved on the outside of the push rod 74 and at the upper end of the horizontal plate 12. The two ends of the compression spring are respectively connected to the top of the horizontal plate 12 and the push rod 74. The bottom end of the protective cover is symmetrically fixedly connected with a mating pressure rod 75.

[0047] The clamping mechanism 6 clamps the battery aluminum shell from the side, the pressing mechanism 5 applies downward pressure to the battery aluminum shell, and the inner support mechanism 8 provides internal support to the right side of the battery aluminum shell. The cutting component 3 is then pressed downwards to cut the battery aluminum shell. During the cutting process, the protective cover drives the mating pressure rod 75 to descend synchronously. The mating pressure rod 75 simultaneously presses the two push rods 74 on the left and right sides. The bottom end of the push rod 74 will contact the top of the rotating plate 73 and gradually press the rotating plate 73 downwards. The vacuum cleaner on the front side of the drawer 711 remains operational during the cutting process. The negative pressure causes air to enter the interior of the elastic chip shield 4 from the gap between the bottom of the elastic chip shield 4 and the adjusting component 63, as well as from the through-hole of the protective cover. The flowing air blows the debris adsorbed on the inner and outer walls of the battery aluminum shell at the cutting location into the drawer 71. Inside, it is easy to absorb and collect the debris generated during the cutting process. The two ends of the battery aluminum shell are blocked by rectangular alignment blocks 82 and push plates 23 respectively, so that the airflow enters the interior of the elastic chip shield 4 through the gaps and through holes as much as possible. The pull-out drawer 711 can be pulled back for timely cleaning. After each cut, the downward pressure of the clamping mechanism 5 is released first, and the clamping force of the clamping mechanism 6 on the battery aluminum shell will be released at the same time. The sliding block 81 moves to the right and drives the cut battery aluminum shell to move a certain distance to the right. As the sliding block 81 continues to move to the right, the spring between the sliding block 81 and the rectangular alignment block 82 will gradually return to the initial state. The inner support bar 84 no longer supports the interior of the battery aluminum shell, and the cut battery aluminum shell is pushed out by the external pushing device, and then the next round of cutting operation is carried out.
