Description

Technical Field

[0001] The utility model relates to the technical field of drawing tooling, and more specifically, to an aluminum alloy battery shell drawing tooling. Background Art

[0002] The aluminum alloy battery shell of new energy vehicles mainly plays a role in protecting the vehicle battery. With the rapid development of the new energy vehicle industry, the demand for battery shells has increased. Currently, the drawing forming process is usually used to manufacture aluminum alloy battery shells.

[0003] The utility model patent with patent announcement number CN218743985U discloses a new energy battery square shell drawing cold rolling integrated machine, including a core pulling base, a drawing main frame and a drawing cold rolling die base, the drawing cold rolling die base is provided with an upper cold rolling roller, a lower cold rolling roller, a left cold rolling roller, a right cold rolling roller and a drawing inner core die, the drawing main frame is provided with a drawing main chain, the two sides of the drawing main chain are provided with drawing linear rails, a drawing trolley is fixed on the drawing main chain, and the drawing main chain is installed in parallel with the drawing trolley. The new energy battery square shell drawing cold rolling integrated machine is mainly used in the production of square aluminum shells of new energy power, and the drawing inner core die is used for positioning, and the outer die adopts a rolling cold rolling roller, which improves the elongation of the square tube, reduces the resistance and friction during drawing, and reduces the occurrence of fracture during drawing, thereby improving the accuracy and finish of the product. When producing different products, it is no longer necessary to replace the entire set of molds, and only the cold rolling roller and the drawing inner core die need to be replaced, thereby reducing production costs.

[0004] However, when this structure is actually used, when the battery shell is pulled, the pulling force is large, resulting in a large clamping force required at the end of the battery shell, which makes the pulled end easily deformed due to the clamping force, and after the pulling is completed, the end that is separated from the mold is easily bounced due to the pulling force, resulting in collision or deformation caused by its own bounce. As a result, after the battery shell is pulled, a long distance of waste will be generated at both ends of the pulled battery shell that needs to be cut off, thereby increasing the manufacturing cost and reducing the production efficiency. Therefore, an aluminum alloy battery shell drawing tool is proposed. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an aluminum alloy battery shell drawing tool, comprising a workbench, a driving device is installed at one end of the workbench, two slide rails are arranged on one side of the driving device, a slider is commonly connected to the top of the two slide rails, a pulling rod is installed on the slider, a top support assembly is installed on the pulling rod, a module is installed on the workbench, a die opening is arranged on the module, a fixing frame is arranged on one side of the die opening, and a blocking assembly is installed on the fixing frame.

[0011] Preferably, a buffer sleeve is sleeved on the clamping roller, and the buffer sleeve is made of rubber material.

[0012] Technical effects and advantages of the utility model:

[0013] 1. Through the arrangement of electric telescopic rods, top plates and pulling rods, compared with the prior art, each electric telescopic rod is extended at a fixed distance according to the thickness of each surface of the battery shell, so that each top plate is fixed on the corresponding inner wall of the battery shell, and the friction between the top plate and the inner wall of the battery shell is increased by providing anti-slip grooves, thereby ensuring the stability of the pulling operation and avoiding separation. The battery shell is pulled by a top support fixing method instead of a traditional end deformation clamping method, thereby reducing the deformation length of the battery shell at the pulling end and reducing the generation of waste;

[0014] 2. Through the arrangement of electric push rods, connecting frames, shaft rods and clamping rollers, compared with the prior art, the electric push rods are extended so that the clamping rollers installed on the connecting frame are pressed against the outer surface of the battery shell.

Then, each electric push rod slowly contracts to release the potential energy inside the battery shell, thereby preventing the battery shell from bouncing and causing deformation, thereby improving the accuracy of the battery shell drawing process.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] As attached Figure 1-5The aluminum alloy battery shell drawing tool shown includes a workbench 1, a driving device 2 is installed at one end of the workbench 1, two slide rails 3 are arranged on one side of the driving device 2, a slider 4 is commonly connected to the top of the two slide rails 3, a drawing rod 8 is installed on the slider 4, a top support assembly 9 is installed on the drawing rod 8, a module 5 is installed on the workbench 1, a die opening 10 is arranged on the module 5, a fixing frame 6 is arranged on one side of the die opening 10, a blocking assembly 7 is installed on the fixing frame 6, a driving sprocket is installed at the output end of the driving device 2, a follower sprocket is rotatably arranged between the two slide rails 3, a chain is connected to the driving sprocket and the follower sprocket, the bottom end of the slider 4 is connected to the chain, one end of the pulling rod 8 is a square structure, and top support assemblies 9 are installed on all four sides.

[0023] During the specific implementation, the pulling rod 8 is inserted into one end of the battery shell for pulling, so that each supporting component 9 supports the battery shell according to the size of the battery shell and fixes it on four sides. At the same time, the outside of the battery shell is clamped by each blocking component 7 on the fixing frame 6. Then, when the driving device 2 is running, the active sprocket drives the chain connected to the follower sprocket to move. During the movement of the chain, the slider 4 is dragged to move on the two slide rails 3, so that the pulling rod 8 follows the movement to pull out the battery shell fixed by each supporting component 9 to perform the pulling operation. When the battery shell is pulled out and comes out of the die 10, each blocking component 7 can block each side of the end of the battery shell to avoid bouncing, and each blocking component 7 slowly shrinks away from the battery shell to release the potential energy generated inside the battery shell, thereby avoiding deformation of the end of the battery shell due to bouncing, thereby reducing the deformation length of the two ends of the battery shell, reducing the generation of waste, reducing production costs, and improving production efficiency.

[0024] As attached Figure 3 As shown, four top support assemblies 9 are provided, and the four top support assemblies 9 together constitute a fixing mechanism. The top support assembly 9 includes an electric telescopic rod 901 and a top plate 902. One end of the electric telescopic rod 901 is installed on the pulling rod 8, and the other end of the electric telescopic rod 901 is installed with a top plate 902, and the top plate 902 is provided with anti-slip grooves.

[0025] During specific implementation, four supporting components 9 form a fixing mechanism, so that the fixing mechanism can fix the inner walls of the battery shell, so that it can be connected and fixed to the battery shell. Specifically, each electric telescopic rod 901 is extended at a fixed distance according to the thickness of each surface of the battery shell, so that each top plate 902 is fixed on the corresponding inner wall of the battery shell, and the friction between the top plate 902 and the inner wall of the battery shell can be increased by providing anti-slip grooves, thereby ensuring the stability of the pulling operation and avoiding separation. The battery shell is pulled by a supporting and fixing method instead of a traditional end deformation clamping method, thereby reducing the deformation length of the battery shell at the pulling end and reducing the generation of waste.

[0026] As attached Figure 3 and Figure 4 As shown, four blocking components 7 are provided, and the four blocking components 7 together constitute a clamping mechanism. The blocking component 7 includes an electric push rod 701, a connecting frame 702, an axle rod 703 and a clamping roller 704. The electric push rod 701 is installed on the fixed frame 6, and the telescopic end of the electric push rod 701 is installed with a connecting frame 702, and the connecting frame 702 is installed with axle rod 703. The clamping roller 704 is rotatably installed on the axle rod 703, and a buffer sleeve is sleeved on the clamping roller 704, and the buffer sleeve is made of rubber material.

[0027] In specific implementation, four blocking components 7 form a clamping mechanism. When the clamping mechanism is in operation, it can clamp the external surfaces of the battery shell, and when the battery shell moves, the friction on the external surface of the battery shell can be reduced by rolling friction, thereby ensuring that the battery shell can be smoothly pulled. Specifically, the electric push rod 701 is extended so that the clamping roller 704 installed on the connecting frame 702 is against the external surface of the battery shell. When the battery shell is pulled out of the module 5, each clamping roller 704 can block each surface of the battery shell, thereby preventing the potential energy inside the battery shell from being released and causing bouncing. Then, each electric push rod 701 slowly contracts, which can release the potential energy inside the battery shell, thereby preventing the battery shell from bouncing and causing deformation, thereby improving the accuracy of the battery shell drawing process, and by setting the buffer sleeve, clamping deformation of the battery shell can be avoided.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
