DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0019] Embodiment 1 like Figure 1 - Fig.11 As shown, a battery casing stamping device proposed in the first embodiment of the present application includes: A mounting frame 1, on which a punch head 102 is mounted via a hydraulic rod 101, and a working plate 103 is mounted on the mounting frame 1, the working plate 103 is used to carry an aluminum plate, and a punching opening 104 for the punch head 102 to pass through is provided on the working plate 103, when in use, the hydraulic rod 101 is used to drive the punch head 102 to approach or move away from the working plate 103, when in use, when it approaches the working plate 103 and squeezes the aluminum plate thereon, the aluminum plate is squeezed into the punching opening 104, thereby bending its side plate to form a shell of the battery shell; The fixing member 2 is mounted on the working plate 103. The fixing member 2 includes an L-shaped plate 201 slidably mounted on the working plate 103. The sliding direction of the L-shaped plate 201 is close to or away from the punching hole 104. A fixing spring 209 is installed between the L-shaped plate 201 and the working plate 103. The fixing spring 209 forces the L-shaped plate 201 to approach the punching hole 104. The L-shaped plate 201 is used to limit the movement of the aluminum plate on the working plate 103. Figure 1From the main perspective, the L-shaped plate 201 slides on the working plate 103 in the horizontal direction. When in use, the L-shaped plate 201 is pulled to move away from each other. After the aluminum plate is placed on the working plate 103, the L-shaped plate 201 is pushed back to its original position by the fixing spring 209, so that it slides toward the punching opening 104 and slides to the maximum sliding limit. At this time, the position of the aluminum plate can be adjusted to align with the punching opening 104 by the extrusion of the L-shaped plate 201, and because a horizontal section of the L-shaped plate 201 is parallel to the upper surface of the working plate 103, the tendency of the aluminum plate to move in the vertical direction can also be limited by the gap between the L-shaped plate 201 and the upper surface of the working plate 103. When the device is punching the aluminum plate, the movement trend of the aluminum plate is that the middle part moves into the punching port 104 in the vertical direction, while the peripheral part is blocked by the horizontal section of the L-shaped plate 201, and will first slide horizontally on the working plate 103, and after a certain bending, when it moves to the punching port 104, it will move in the vertical direction. During the movement, the aluminum plate can also form a shell. When the shell is formed, if the aluminum plate is only limited in the horizontal direction, when the punch head 102 directly presses the aluminum plate, the aluminum plate will directly tilt up against the side wall of the punching port 104. The movement amplitude of the four side walls is large and the movement speed is fast. Although the efficiency is high, the movement speed of the aluminum plate is too fast, and the mutual squeezing force between them is large, which is easy to form defective products. The setting of the L-shaped plate 201 reduces the movement speed of the peripheral side of the aluminum plate when it is punched, and reduces the possibility of defective products. The blanking piece 3 is installed on the mounting frame 1. The blanking piece 3 includes a connecting plate 301. The connecting plate 301 is slidably installed on the mounting frame 1. The connecting plate 301 is located below the working plate 103. A hinged plate 302 is hinged on the connecting plate 301. A bearing plate 304 is installed on the hinged plate 302 through a connecting spring 303. The connecting spring 303 forces the bearing plate 304 to be inserted into the punching port 104. In normal state, the bearing plate 304 is used to block the punching port 104. When the punch head 102 pushes the aluminum plate, the bearing plate 304 is also pressed downward. When the aluminum plate is pressed, the bearing plate 304 is also supported, which increases the stability of the aluminum plate when it is deformed, thereby further reducing the generation of defective products. The unloading member 3 also includes a driving part connected to the telescopic end of the hydraulic rod 101, and the driving part is connected to the connecting plate 301. When the telescopic end of the hydraulic rod 101 is away from the working plate 103, the driving part drives the connecting plate 301 away from the bottom of the working plate 103. A push rod 305 is installed on the mounting frame 1. When the hinge plate 302 falls, the push rod 305 causes the hinge plate 302 to tilt. When in use, the driving part is connected to the telescopic end of the hydraulic rod 101, so that when the hydraulic rod 101 is pressed and reset, the connecting plate 301 moves downward through the cooperation of the driving part. When its movement drives the hinge plate 302 to move to contact with the push rod 305, the position of the push rod 305 remains unchanged, and the connecting plate 301 continues to fall. Through the resistance of the push rod 305, the hinge plate 302 is tilted, and the shell on the carrying plate 304 is unloaded; The hinge plate 302 is provided with a plate body on one side facing the push rod 305, so that the center of gravity of the entire plate body is close to the side. When the hinge plate 302 is reset, the contact with the push rod 305 is released and the plate body is reset by gravity. When the connecting plate 301 is reset, the bearing plate 304 is inserted into the punching opening 104, and the rotation of the hinge plate 302 is also restricted. The bearing plate 304 not only has the function of bearing the aluminum plate, but also has the function of limiting the rotation of the hinge plate 302, which increases the practicality of the device. Compared with the prior art, the punch head 102 is driven by the hydraulic rod 101 on the mounting frame 1, and the aluminum plate is fixed by the gap formed between the L-shaped plate 201 of the fixing member 2 and the working plate 103. When the punch head 102 punches the aluminum plate, it is squeezed into the punching port 104, so that the aluminum plate is bent on all sides. When the stamping is completed to form a shell, the hydraulic rod 101 is reset, and the connecting plate 301 is moved away from the working plate 103 through the driving part, so that the shell falls with it. When it moves to the point where the hinge plate 302 contacts the pushing rod 305, the hinge plate 302 is tilted, and the shell is unloaded, thereby increasing the practicability of the device.

[0020] Embodiment 2 like Figure 3 and Fig.10 As shown, the second embodiment further discloses the fixing member 2, the blanking member 3, the connecting plate 301 and the hinge plate 302 on the basis of the first embodiment. In the second embodiment, the fixing member 2 further includes: A turntable 202 is rotatably mounted on the working plate 103, a hinge rod 203 is hinged on the turntable 202, and the turntable 202 is mounted at the corner of the punching port 104; The resistance block 204 is slidably mounted on the working plate 103. The number of the resistance blocks 204 is the same as that of the L-shaped plate 201, both of which have four, while the turntable 202 has two. The resistance block 204 is provided with a force-applying inclined surface, and the L-shaped plate 201 is provided with a force-receiving inclined surface. The sliding direction of the resistance block 204 is perpendicular to the sliding direction of the L-shaped plate 201. The hinge rod 203 is slidably hinged to the resistance block 204, so as to Figure 1 From the main perspective, the resistance block 204 slides on the working plate 103 in the horizontal direction. Two hinged rods 203 are hinged on a turntable 202 for connecting two adjacent resistance blocks 204. A groove is provided on the resistance block 204, and one end of the hinged rod 203 connected thereto can slide and rotate thereon, so that when the turntable 202 rotates, the resistance block 204 is pulled close to or away from the L-shaped plate 201 through the hinged rod 203. A block is installed on the working plate 103, and a rod is installed on the resistance block 204. The block is provided with a hole for the rod to pass through, which is used to limit the sliding direction of the resistance block 204 so that it can only approach or move away from the L-shaped plate 201 in the horizontal direction. When in use, when the turntable 202 rotates, the hinged rod 203 is driven to approach the L-shaped plate 201, so that the resistance block 204 moves in the direction close to the L-shaped plate 201, and the resistance block 204 resists the L-shaped plate 201 through the guidance of the force-bearing inclined surface and the force-applying inclined surface, and the tendency of the L-shaped plate 201 to move away from the punching port 104 is restricted, thereby increasing the stability of the L-shaped plate 201 when in use. When the turntable 202 rotates in the opposite direction to drive the hinged rod 203 away from the L-shaped plate 201, the resistance block 204 is pulled to release the resistance to the L-shaped plate 201, so that the sliding of the L-shaped plate 201 is restored, which is convenient for the operator to load the aluminum plate; The rotating rod 205 is rotatably mounted on the working plate 103. The rotating rod 205 is connected to the rotating shaft of the turntable 202 through a pulley assembly. There are two pulley assemblies, which connect the rotating rod 205 to the rotating shafts of the two turntables 202 respectively. One pulley assembly is composed of two pulleys and a belt, one of which is connected to the rotating rod 205, and the other pulley is connected to the rotating shaft of the turntable 202. The belt is used to transmit and connect the two pulleys. An insertion cavity 2051 is opened on the rotating rod 205, and a slider 2052 is installed in the insertion cavity 2051. A hydraulic rod 101 is installed on the telescopic end. A mounting plate 206 is provided, on which a driving rod 207 for being inserted into the insertion cavity 2051 is installed. A spiral groove 208 for slidingly cooperating with the slider 2052 is provided on the driving rod 207. The angle between the starting end and the ending end of the spiral groove 208 is ninety degrees, so that the maximum rotation range of the rotating rod 205 is limited. When the driving rod 207 reciprocates with the telescopic end of the hydraulic rod 101, the slider 2052 is pushed tangentially through the spiral groove 208, thereby causing the rotating rod 205 to reciprocate, and the rotation angle is plus or minus ninety degrees when it is in the starting position; During use, when the hydraulic rod 101 is close to the working plate 103, it drives the driving rod 207 to rotate in the insertion cavity 2051, and through the cooperation between the spiral groove 208 and the slider 2052, drives the rotating rod 205 to rotate, and then the turntable 202 rotates, so that the resistance block 204 restricts the sliding of the L-shaped plate 201, thereby increasing its stability when limiting the aluminum plate. When the hydraulic rod 101 is reset, it pulls the driving rod 207 to reset, thereby driving the rotating rod 205 to reverse, so that the resistance block 204 releases the restriction on the sliding of the L-shaped plate 201, which facilitates the loading of the aluminum plate and increases the practicality of the device.

[0021] like Figure 4 , Figure 5 and Figure 7 As shown, in the second embodiment, the driving part of the blanking member 3 includes: The sliding rod 306 is mounted on the mounting plate 206, and a connecting pipe 307 is mounted on the mounting frame 1. The sliding rod 306 is slidably inserted in the connecting pipe 307. An air outlet 3061 is provided at the end of the sliding rod 306 located in the connecting pipe 307. An air inlet 3062 connected to the air outlet 3061 is provided on the side wall of the sliding rod 306. An air outlet pipe 308 is installed on the connecting pipe 307. The air outlet pipe 308 is used to make the air flow in the connecting pipe 307 flow to the outside of the connecting pipe 307 in one direction. A one-way valve is installed in the air outlet pipe 308 so that the air flow can only flow from the inside of the connecting pipe 307 to the outside. A cavity is constructed on the sliding rod 306. The cavity makes the air inlet 3062 communicate with the air outlet 3061. Under normal conditions, the air inlet 3062 is inserted in the connecting pipe 307. A pull rod 309 is mounted on the connecting plate 301. The pull rod 309 is slidably inserted into the connecting pipe 307. A return spring 3010 is installed between the connecting plate 301 and the connecting pipe 307. The return spring 3010 forces the connecting plate 301 to move away from the connecting pipe 307. When in use, when the hydraulic rod 101 falls, the sliding rod 306 slides downward, and at this time, it presses the air flow in the connecting pipe 307, and the air flow is ejected from the air outlet pipe 308. When stamping, it will not affect the movement of the connecting plate 301, thereby reducing the possibility of the connecting plate 301 and the hinged plate 302 colliding with the working plate 103 during stamping and causing greater wear; When the hydraulic rod 101 is reset, the sliding rod 306 pulls the air flow in the connecting pipe 307. At this time, the air inlet 3062 is still located in the connecting pipe 307, which can form a negative pressure inside it, and then pull the pulling rod 309, so that the reset spring 3010 is compressed, and the connecting plate 301 moves downward, so that the hinge plate 302 can move to a position that conflicts with the pushing rod 305, and the shell is unloaded. When continuing to pull, the air inlet 3062 moves to the outside of the connecting pipe 307 and communicates with the outside world, so that the outside air flow enters the connecting pipe 307 through the air inlet 3062 and the air outlet 3061, and then the negative pressure inside it is released. At this time, the force exerted by the internal air pressure of the connecting pipe 307 on the pulling rod 309 is released. At this time, the reset spring 3010 pushes the connecting plate 301 to reset, which is convenient for the next unloading, thereby increasing the practicality of the device.

[0022] like Figure 8 As shown, in embodiment 2, a guide rod 6 is installed at the bottom of the load-bearing plate 304, and the guide rod 6 is slidably matched with the hinge plate 302. The connecting spring 303 is sleeved on the outside of the guide rod 6, and a hole for accommodating the guide rod 6 is opened on the hinge plate 302. The inner wall of the hole restricts the side wall of the guide rod 6 so that it can only slide on the hinge plate 302 in a straight line direction, thereby increasing the stability of the load-bearing plate 304 when sliding. The connecting spring 303 is sleeved on the outside of the guide rod 6, which can also limit the deformation direction of the connecting spring 303, thereby increasing the stability of the connecting spring 303 when elastic deformation occurs.

[0023] like Figure 5 and Figure 8 As shown, in the second embodiment, an arc groove 4 is provided on the connecting plate 301, the center of the arc side of the arc groove 4 is co-centered with the center of the hinge point of the hinge plate 302, and an intermediate plate 5 is slidably installed in the arc groove 4, so that the sliding path of the intermediate plate 5 in the arc groove 4 is co-centered with the rotation path of the hinge plate 302 on the connecting plate 301; A circular plate 7 is installed at the free end of the guide rod 6, and the diameter of the circular plate 7 is larger than the diameter of the guide rod 6. A hole 8 for the circular plate 7 to pass through is opened on the middle plate 5. A limited slide plate 9 is slidably installed on the middle plate 5 through a resistance spring 10. The limited slide plate 9 is used to be inserted between the circular plate 7 and the middle plate 5 so that the distance between the guide rod 6 and the middle plate 5 remains unchanged. An inclined surface is opened on the limited slide plate 9. When the bearing plate 304 is squeezed, the guide rod 6 slides downward, so that the circular plate 7 moves to the bottom of the middle plate 5 through the hole 8, and resists the limited slide plate 9 during the process, so that it is away from the hole 8. When the guide rod 6 continues to be pressed and slides downward, the diameter of its rod body is smaller than the diameter of the circular plate 7, so that the limited slide plate 9 is pushed by the resistance spring 10 and contacts the rod body of the guide rod 6. At this time, the limited slide plate 9 blocks the circular plate 7 and limits its tendency to move in the reset direction, thereby limiting the sliding of the guide rod 6 on the middle plate 5, so that the position between the bearing plate 304 and the middle plate 5 is at the minimum distance that can be achieved between the two. When the shell is stamped, the slide plate 9 is used to limit the sliding of the guide rod 6, so that the bearing plate 304 is close to the middle plate 5, and the distance between the stamped shell and the connecting plate 301 is small, so that the connecting plate 301 does not need to move downward too much distance to make the shell completely exposed outside the stamping port 104, which is convenient for unloading. Among them, since the movement path of the middle plate 5 is cocentric with the path of the hinge plate 302, even if the guide rod 6 connects the two, the middle plate 5 will not affect the rotation of the hinge plate 302, which increases the feasibility of the device; A release member is installed on the connecting plate 301, and the release member is used to move the limiting slide plate 9 away from the circular plate 7. When the connecting plate 301 is reset, the limiting slide plate 9 is moved away from the circular plate 7 through the cooperation of the release member, so that the restriction on the sliding of the guide rod 6 is released, and then the connecting spring 303 pushes the supporting plate 304 to reset, which is convenient for the next stamping.

[0024] like Figure 5 , Fig. 9 and Fig.11 As shown in the second embodiment, the release member includes an L-shaped block 11 mounted on the working plate 103, the end of the L-shaped block 11 is provided with an inclined surface, and a resisting rod 15 is slidably mounted on the connecting plate 301 through a push spring 12, so as to Figure 1 From the main perspective, the abutment rod 15 is slidably mounted on the connecting plate 301 in the horizontal direction; A force block 16 is installed on one end of the resistance rod 15 close to the L-shaped block 11, and an inclined surface parallel to the inclined surface on the L-shaped block 11 is provided on the resistance rod 15. A through slot 13 penetrating the middle plate 5 is provided on the middle plate 5, and a push block 14 slidingly matched with the through slot 13 is installed on the limiting slide plate 9. When the connecting plate 301 moves to the point where the force block 16 contacts the L-shaped block 11, the resistance rod 15 pushes the push block 14 away from the channel 8, and one end of the push block 14 is located above the middle plate 5 through the through slot 13. When in use, since the L-shaped block 11 is installed on the working plate 103, its position remains unchanged. When the connecting plate 301 falls, the interference between the L-shaped block 11 and the force-bearing block 16 is released, and the push spring 12 pulls the interference rod 15 away from the push block 14, so that the interference spring 10 can push the limiting slide plate 9 to slide in the direction of the channel 8, which is convenient for the subsequent sliding of the circular plate 7 and the guide rod 6 to be limited. When the connecting plate 301 is pushed to reset by the reset spring 3010, the abutting rod 15 and the force block 16 gradually approach and abut against the L-shaped block 11. After the connecting plate 301 is reset, the L-shaped block 11 abuts and pushes the force block 16. The abutting rod 15 is forced to slide in the direction of the pushing block 14 through the guidance of the inclined surfaces on both sides, and pushes the pushing block 14 to move away from the channel 8. Since the pushing block 14 is connected to the limiting slide plate 9, the limiting slide plate 9 is driven away from the channel 8, so that the limiting slide plate 9 releases the obstruction of the circular plate 7, and then releases the restriction on the sliding of the guide rod 6, so that the supporting plate 304 can be reset, thereby increasing the practicality of the device.

[0025] Embodiment 3 like Figure 1 - Fig.11 As shown, the third embodiment is further disclosed on the basis of the second embodiment. In the third embodiment, an extension plate 17 is installed on the hinge plate 302, and a movable groove 18 is opened on the extension plate 17. A movable rod 19 that slides with the movable groove 18 is installed on the working plate 103. The extension plate 17 and the movable rod 19 are both located on one side of the hinge plate 302. Figure 6 As shown, when the hinge plate 302 is in use, the side wall of the movable rod 19 limits the inner wall of the movable groove 18, which reduces the possibility of the hinge plate 302 shaking when rotating, increases the stability of the hinge plate 302 when in use, and the movable rod 19 can slide along its own axial direction in the movable groove 18 and can also slide along the length direction of the movable groove 18 to meet the activity of the hinge plate 302; The extension plate 17 and the movable rod 19 are arranged on one side of the hinge plate 302, which reduces the possibility of the two blocking the shell during unloading. Since the extension plate 17 is installed on the hinge plate 302, the movable rod 19 is connected to the movable groove 18 thereon, and the movable rod 19 will inevitably have a projection on the hinge plate 302 in the opposite direction of the shell unloading, so that when the shell slides down, one side of it will contact the movable rod 19, and this side will fall later than the rest of the shell. The blocking of the movable rod 19 slows down the falling speed of the shell, reduces the possibility of damage to the shell during falling, and increases the practicality of the movable rod 19.

[0026] In the third embodiment, a limited rotation block 20 is installed on the hinge axis of the hinge plate 302, and a limited rotation groove 21 for accommodating the limited rotation block 20 is opened on the L-shaped block 11. When the hinge plate 302 is reset or the device is not stamped, the limited rotation block 20 is inserted into the limited rotation groove 21. The limited rotation block 20 is not circular. The inner wall of the limited rotation groove 21 blocks the side wall of the limited rotation block 20, thereby limiting the rotation of the hinge plate 302, further increasing the stability of the hinge plate 302 and the supporting plate 304 when the aluminum plate is stamped, thereby increasing the practicality of the device.

[0027] In embodiment three, a rotating roller 22 is rotatably installed on the working plate 103 around the punching port 104. As described above, the movement state of the aluminum plate around the working plate 103 is first horizontally sliding and bending and then being squeezed in the vertical direction by the punching head 102 and the inner wall of the punching port 104. The rolling cooperation between the rotating roller 22 and the aluminum plate facilitates the sliding of the side of the aluminum plate on the working plate 103, thereby increasing the practicability of the device.

[0028] In Example 3, a rubber roller 23 is rotatably installed on the side of the L-shaped plate 201 that contacts the aluminum plate. The lowest point of the rubber roller 23 is closer to the upper surface of the working plate 103 than the bottom of the horizontal section of the L-shaped plate 201. When the L-shaped plate 201 restricts the aluminum plate, the rubber roller 23 and the aluminum plate are in a state of conflict in the vertical direction, which further increases the fixing effect of the L-shaped plate 201 on the aluminum plate. When the side of the aluminum plate moves in the horizontal direction, it can also cooperate with the aluminum plate in rolling to facilitate the movement of the aluminum plate, thereby increasing the practicality of the device.

[0029] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
