Description

Technical Field

[0001] This utility model belongs to the field of battery steel shell production technology, and in particular relates to an automatic shell removal device for a battery steel shell stretching and forming machine. Background Technology

[0002] The battery steel shell stretching forming machine is a specialized piece of equipment used to manufacture cylindrical or square battery steel shells (such as lithium batteries and nickel-metal hydride batteries). It primarily uses a multi-station continuous stretching process to process metal sheets (such as nickel-plated steel and stainless steel) into battery shells that meet the required specifications. The core structure of this equipment includes a feeding system, a stamping and stretching unit, a hydraulic / servo system, a mold system, and an automated control system. The feeding system is responsible for uncoiling, leveling, and feeding the metal coil. The stamping and stretching unit uses a multi-station press and molds to progressively stretch the metal sheet into a deep cylindrical shape, including initial stretching, multiple stretching processes, and finishing trimming. After stretching the battery steel shell, it needs to be unwound using an unshelling device. However, in practical use, it still has the following drawbacks: When the automatic shell removal device of the battery steel shell stretching forming machine is in operation, it needs to be protected by guardrails or baffles to prevent the steel shell from falling to the ground. However, in use, the baffles and other structures will block the mold above from falling, affecting the forming effect. Secondly, after the steel shell is stretched and formed, the steel shell is still left on the mold after being unloaded by the automatic shell removal device. Operators need to approach and remove it, collect it and transport it to the next production equipment. The operation requires a lot of manpower and the work efficiency is low. Utility Model Content

[0003] The purpose of this utility model is to provide an automatic shell removal device for a battery steel shell stretching and forming machine. By setting a forming block, a pushing component, a movable chamber, and a fixing plate, it solves the problem that the structure of the automatic shell removal device for the battery steel shell stretching and forming machine that prevents the steel shell from falling easily obstructs the mold and other structures from falling, affecting the forming effect, and that removing the battery steel shell after shell removal requires a lot of manual labor.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to an automatic shell ejection device for a battery steel shell stretching and forming machine, comprising a forming block, a pushing component, a movable chamber, and a fixed plate. Movable chambers are fixed to both sides of the forming block, and arc-shaped springs are fixed to the two short sides of the bottom of each movable chamber. A limiting plate is movably connected to the upper part of the movable chamber, extending beyond the top of the movable chamber. A pushing component is located in the lower part of the movable chamber. A fixed plate is located at the upper part of one end of the forming block, and a pushing cylinder is fixed to the top of the fixed plate. The telescopic end of the pushing cylinder faces the top of the forming block, and a movable plate is fixed to the telescopic end of the pushing cylinder. During operation, the forming block stretches and forms the battery steel shell. The pushing component drives the battery steel shell to eject from the forming opening within the forming block. The movable chamber movably connects to the limiting plate that restricts the ejected battery steel shell. The fixed plate supports the pushing cylinder on the fixed plate.

[0005] Furthermore, the top of the molding block has molding openings at equal intervals along the center line parallel to the long side, and the bottom of the molding block has a cavity. All the molding openings are connected to the cavity. A support plate is fixed to the bottom of the molding block. The molding openings at equal intervals along the long side of the top of the molding block are used for stretching and forming the battery steel shell. The cavity at the bottom is connected to all the molding openings to facilitate pushing the component installation. The support plate is fixed to the bottom of the molding block to ensure that the whole is stably supported on the working plane.

[0006] Furthermore, the pushing assembly includes a pushing plate and a pushing column. The top of the pushing plate is fixed with a pushing column corresponding to each forming port position. The pushing plate is movably connected in the cavity. The top of the pushing column is movably connected in the lower part of the forming port. The pushing plate and the forming port are fixed with the pushing column in a one-to-one correspondence. The pushing plate moves up and down in the cavity, driving the pushing column to push out from the lower part of the forming port, realizing the removal of the battery steel shell after forming. The pushing column is movably connected to the forming port to ensure accurate pushing.

[0007] Furthermore, the pushing assembly also includes electric push rods. Electric push rods are fixed at both short sides of the bottom of the molding block. The telescopic ends of the two electric push rods are respectively fixed at the two short sides of the bottom of the pushing plate. The two electric push rods are symmetrically fixed at the short sides of the bottom of the molding block, and synchronously control the lifting and lowering of the pushing plate. The actions are coordinated by a unified controller to ensure the smooth movement of the pushing plate and avoid jamming or tilting.

[0008] Furthermore, the movable compartment is open on the side near the molding block, and the top of the movable compartment is flush with the top of the molding block. Two arc-shaped springs in the same movable compartment are fixed together to the bottom of the limiting plate in the movable compartment. The movable compartment is open on the side near the molding block, and the top is flush with the molding block. The limiting plate achieves elastic reset through the bottom double arc-shaped springs. When pressed down, the limiting plate retracts into the compartment. After molding, the springs rebound and reset, constraining the position of the battery steel shell.

[0009] Furthermore, the top of the fixed plate is flush with the top of the forming block, and the movable plate is set on the top of the fixed plate. Support legs are fixed at the two short sides of the bottom of the fixed plate. The fixed plate is supported by the support legs, and the top is flush with the forming block. The movable plate is driven by a push cylinder to push the battery steel shell after shell removal laterally away from the forming block to the next station. After the cylinder retracts, the movable plate resets.

[0010] This utility model has the following beneficial effects: This invention solves the problem that the automatic shell removal device of a battery steel shell stretching forming machine, by setting a forming block, a pushing component, and a movable chamber, can easily obstruct the mold and other structures from falling, thus affecting the forming effect. During the stretching forming process of the battery steel shell, the forming mold and other components are pressed down. After contacting the top of the limiting plate, the arc-shaped spring is compressed during the pressing process, and the limiting plate enters the movable chamber, preventing it from affecting the forming of the battery steel shell. After the forming is completed, the arc-shaped spring, under the elastic action, drives the limiting plate to return to its original position, making it less likely for the automatic shell removal device of the battery steel shell stretching forming machine to obstruct the mold from falling.

[0011] This invention solves the problem of excessive manual labor required to remove the battery steel shell after the automatic shell removal device of the battery steel shell stretching and forming machine is implemented by setting a forming block and a fixing plate. After the battery steel shell is formed in the forming opening of the forming block, and the forming mold leaves the top of the forming block, the battery steel shell is removed. Then, the pushing cylinder is activated, which pushes the moving plate to the top of the forming block, drives the battery steel shell to the top of the forming block, and pushes the battery steel shell on the top of the forming block to the short side away from the fixing plate, and pushes it into the next production equipment. The pushing cylinder is then restarted, driving the moving plate to reset. This eliminates the need for manual operation to remove the battery steel shell after the automatic shell removal device of the battery steel shell stretching and forming machine is implemented, and also eliminates the need for manual removal of each steel shell, making the work more convenient.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0016] Please see Figure 1-4 This utility model relates to an automatic shell removal device for a battery steel shell stretching and forming machine, comprising a forming block 1, a pushing component 2, a movable chamber 3, and a fixed plate 4. Movable chambers 3 are fixed to both sides of the forming block 1. The forming block 1 is used for stretching and forming the battery steel shell. A limiting plate 302 is movably connected to the movable chamber 3, and arc-shaped springs 301 are fixed to the two short sides of the bottom of the movable chamber 3. The limiting plate 302 is movably connected to the upper part of the movable chamber 3, extending beyond the top of the movable chamber 3. During operation, when the limiting plate 302 is compressed, the arc-shaped springs 301 enter the movable chamber 3. After the limiting plate 302 is released, the limiting plate 302... The elastic reset of the arc-shaped spring 301 and the limiting plate 302 restrict the position of the battery steel shell during shell removal. The lower part of the movable chamber 3 is provided with a pushing component 2, which pushes the formed battery steel shell in the forming block 1. A fixing plate 4 is provided on the upper part of one end of the forming block 1. The fixing plate 4 supports the pushing cylinder 401 on it. The top of the fixing plate 4 is fixed with the pushing cylinder 401. The telescopic end of the pushing cylinder 401 faces the top of the forming block 1, and the telescopic end of the pushing cylinder 401 is fixed with a moving plate 402. The pushing cylinder 401 drives the moving plate 402 to push the removed battery steel shell to the side of the forming block 1 away from the fixing plate 4.

[0017] Specifically, the top of the molding block 1 has molding openings 102 at equal intervals along the center line parallel to the long side, and the bottom of the molding block 1 has a cavity 101. All molding openings 102 are connected to the cavity 101. A support plate 103 is fixed to the bottom of the molding block 1. During operation, the molding block 1 performs the molding operation of the battery steel shell through the molding openings 102. The cavity 101 is used to set the push plate 202 and the push column 203. The support plate 103 supports the molding block 1 on the working plane.

[0018] Furthermore, the pushing component 2 includes a pushing plate 202 and a pushing column 203. The top of the pushing plate 202 is fixed with a pushing column 203 corresponding to the position of each forming port 102. The pushing plate 202 is movably connected in the cavity 101, and the top of the pushing column 203 is movably connected in the lower part of the forming port 102. When the pushing component 2 is working, when the pushing plate 202 is pushed, it drives the pushing column 203 to rise and fall in the forming port 102 on the forming block 1.

[0019] Furthermore, the pushing component 2 also includes electric push rods 201. Electric push rods 201 are fixed at the two short sides of the bottom of the molding block 1. The telescopic ends of the two electric push rods 201 are respectively fixed at the two short sides of the bottom of the pushing plate 202. The two electric push rods 201 are controlled by the same controller to lift and lower synchronously. The two electric push rods 201 drive the pushing plate 202 to lift and lower. During the lifting and lowering of the pushing plate 202, the pushing column 203 is driven to lift and lower.

[0020] The operation process of this embodiment is as follows: After the battery steel shell is formed in the forming block 1, two electric push rods 201 are activated. The electric push rods 201 drive the push plate 202 and push column 203 at the bottom of the forming block 1 to rise. After the push column 203 rises, it pushes the battery steel shell formed in the forming opening 102 at the top of the forming block 1 to exit. The battery steel shell after exiting is placed between two limiting plates 302 and is restricted to the top of the forming block 1. During the stretching and forming process of the battery steel shell, the forming mold and other parts are pressed down. After contacting the top of the limiting plate 302, the arc spring 301 is compressed during the pressing process. The limiting plate 302 enters the movable chamber 3 to prevent it from affecting the forming of the battery steel shell. After the forming is completed, the mold leaves the top of the forming block 1. Under the elastic action, the arc spring 301 drives the limiting plate 302 to reset. Specific Implementation Example 2

[0021] Please see Figure 1 , 25. Based on the specific embodiment 1, the movable chamber 3 is set with an opening on the side near the molding block 1. The top of the movable chamber 3 is flush with the top of the molding block 1. Two arc-shaped springs 301 in the same movable chamber 3 are fixed together to the bottom of the limiting plate 302 in the movable chamber 3. When the movable chamber 3 is working, it is fixed to the limiting plate 302 by the arc-shaped springs 301, so that after the limiting plate 302 enters the movable chamber 3, it can be reset after the mold leaves the top of the molding block 1.

[0022] Specifically, the top of the fixed plate 4 is flush with the top of the forming block 1, and the movable plate 402 is set on the top of the fixed plate 4. Support legs 403 are fixed on the two short sides of the bottom of the fixed plate 4, and the fixed plate 4 is supported on the working surface by the support legs 403.

[0023] The operation process of this embodiment is as follows: During operation, after the battery steel shell in the forming port 102 of the forming block 1 is formed, when the forming mold leaves the top of the forming block 1 and the battery steel shell is unpacked, the pushing cylinder 401 is started. The pushing cylinder 401 pushes the moving plate 402 to the top of the forming block 1, drives the battery steel shell to the top of the forming block 1, pushes the battery steel shell on the top of the forming block 1 to the short side away from the fixed plate 4, pushes it into the next production equipment, and restarts the pushing cylinder 401 to drive the moving plate 402 to the reset.
