Description

Technical Field

[0001] The utility model relates to the technical field of blade battery shell processing, in particular to a blade battery shell surface anti-strain roller forming device. Background Art

[0002] Blade batteries are a type of sheet-shaped single battery with a small overall thickness but large length and width. During production and processing, in order to ensure the safety of the single blade battery, it is usually formed by continuous roll-forming of aluminum strips, and then high-frequency welding is performed at the closed cross-section. During the rolling process, multiple continuous pressure rollers are usually used to roll it, causing it to undergo plastic deformation.

[0003] In the existing scheme, upper and lower concave and convex rollers are used for cooperative extrusion. During the extrusion process, the contact between the upper and lower concave and convex rollers is linear contact rather than contact of the entire roller surface. The contact part of the roller causes the aluminum plate to deform, and the remaining non-contact part is used to position the aluminum plate during the rolling process to prevent excessive deformation. By using multiple continuous rollers, the rolling deformation of the rollers gradually increases, thereby causing the aluminum plate to gradually bend and deform.

[0004] However, in the actual processing process, multiple continuous pressing rollers have different diameters of the contact points, and the rolling process is a continuous operation. On the one hand, the contact point diameters of the upper and lower concave-convex rollers are different, resulting in linear speed differences between the same group of concave-convex rollers. At the same time, the contact point diameters of the front and rear groups of convex rollers are different, which also leads to different moving linear speeds of the front and rear roller groups. As a result, the linear speed difference is prone to occur in the entire continuous rolling process, resulting in scratches on the surface of the aluminum strip, affecting subsequent use. For this purpose, a blade battery shell surface anti-strain rolling forming device is provided to solve the above problems. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a blade battery shell surface anti-strain roll-forming device, which solves the problem that during the continuous rolling process of the existing blade battery shell, the aluminum substrate is easily scratched due to the different linear speeds of the contact points of the upper and lower concave and convex rollers, as well as the different linear speeds of the front and rear roller groups, resulting in an overall linear speed difference, which affects subsequent use.

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0026] The embodiment of the present application solves the problem that in the continuous rolling process of the existing blade battery shell, the aluminum substrate is easily scratched due to the different linear speeds of the contact points of the upper and lower concave and convex rollers, as well as the different linear speeds of the front and rear roller groups, resulting in an overall linear speed difference, which affects the subsequent use.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0028] The embodiment of the utility model discloses a device for rolling-forming a blade battery shell to prevent the surface from being damaged.

[0029] According to the attached Figure 1-5 As shown, it includes a support member 1 and a rolling member 2 installed on the support member 1, the rolling member 2 includes a convex pressing roller 21 and a concave pressing roller 22, and the outer surfaces of both ends of the convex pressing roller 21 and the concave pressing roller 22 are provided with symmetrical rolling contact points;

[0030] A linear speed synchronization mechanism 3 is provided at the end of the rolling member 2. The linear speed synchronization mechanism 3 includes a driving gear 33 and a driven gear 32. The driving gear 33 is fixedly installed coaxially with the concave pressing roller 22, and the driven gear 32 is fixedly installed coaxially with the convex pressing roller 21. The driving gear 33 and the driven gear 32 are engaged with each other to keep the linear speed of the rolling contact point of the convex pressing roller 21 and the concave pressing roller 22 the same.

[0031] During use, the aluminum substrate passes between the convex pressing roller 21 and the concave pressing roller 22. At this time, the outer surfaces of both ends of the convex pressing roller 21 and the concave pressing roller 22 respectively have a group of rolling contact points for extrusion contact with the aluminum strip roll. The driving gear 33 and the driven gear 32 cooperate to make the linear speed of the rolling contact points of the convex pressing roller 21 and the concave pressing roller 22 consistent. At the same time, multiple groups of concave pressing rollers 22 are connected by a transmission chain, and the driven gears 32 at the ends of multiple convex pressing rollers 21 are designed separately, so that the linear speed of each group of rolling parts 2 is consistent, thereby solving the problem of inconsistent linear speeds of the convex pressing roller 21 and the concave pressing roller 22 in a single group of rolling parts 2 and inconsistent linear speeds between the front and rear groups of rolling parts 2.

[0032] The support member 1 includes a supporting base plate 11 and a mounting column 12 fixedly arranged on the supporting base plate 11. The convex pressing roller 21 and the concave pressing roller 22 are both mounted on the outer surface of the mounting column 12. The convex pressing roller 21 and the concave pressing roller 22 are respectively coaxially fixed with a rotating shaft 23 inside. A support seat 13 is installed on the outer surface of the mounting column 12. The rotating shaft 23 is rotatably arranged in the support seat 13. An axle seat 14 is fixedly arranged inside the support seat 13. The rotating shaft 23 is connected to the axle seat 14 by a bearing. Through the axle seat 14, the convex pressing roller 21 and the concave pressing roller 22 are respectively rotatably arranged in the support member 1 through the rotating shaft 23, so that the distance between the convex pressing roller 21 and the concave pressing roller 22 remains constant.

[0033] The top of the mounting column 12 is fixedly connected to a support plate 15, and the top of the support plate 15 is provided with a lifting reducer 16, which is used to drive the two groups of support seats 13 to open and close. The support seat 13 includes a fixed seat 131 installed at both ends of the concave pressing roller 22 and a movable seat 132 installed at both ends of the convex pressing roller 21. The top of the movable seat 132 is fixedly provided with a suspension rod 19, and the top of the suspension rod 19 is fixedly connected to the output end of the lifting reducer 16. A support ring 110 is fixedly provided on the outer surface of the bottom end of the mounting column 12, and the fixed seat 131 is fixedly installed with the support ring 110. A servo motor 17 is fixedly provided on the side of a group of support plates 15, and a connecting rod 18 is installed between the two groups of lifting reducers 16. The servo motor 17 is connected to the two groups of lifting reducers 16 through the connecting rod 18.

[0034] By starting the servo motor 17, the servo motor 17 drives the output ends of the two sets of lifting reducers 16 to synchronously perform telescopic driving through the connecting rod 18, so that the two sets of movable seats 132 move up and down synchronously, thereby separating the convex pressing roller 21 from the concave pressing roller 22, making it easier for the aluminum strip to be loaded.

[0035] The driving gear 33 and the driven gear 32 are respectively fixed on the outer surfaces of the two groups of rotating shafts 23, and the end of the rotating shaft 23 is fixedly provided with a transmission wheel 31. In actual application, multiple groups of the device are linearly distributed, and multiple groups of concave pressing rollers 22 have the same structure. A transmission chain is used to connect the two groups of synchronous transmissions, so as to keep the linear speed of the multiple groups of concave pressing rollers 22 the same, and the outer diameters of the rolling contact points of the multiple groups of convex pressing rollers 21 are in an increasing state. Therefore, it is necessary to design the multiple groups of driven gears 32 separately. The number of teeth of the multiple groups of driven gears 32 increases as the outer diameter of the rolling contact point increases, so that the multiple groups of convex pressing rollers 21 can also maintain the same linear speed, thereby avoiding the front and rear groups of rolling parts 2 from causing damage to the aluminum substrate due to different linear speeds.
