Fig. 2 shows the utility model discloses in be applicable to the shaping device's of lithium cell top cap structural schematic diagram, it sets up in the front process of top cap charging equipment, including Y shaping device 1 and X shaping device 2, arrange according to the preface. Wherein, the Y-shaped reshaping device 1 is used for reshaping the top cover in the front-back direction; the X-ray orthopedic device 2 is used for performing shape correction on the top cover in the left-right direction. In the actual working process, firstly, the position of the top cover needs to be locked, and then the shape of the support of the top cover is corrected in the front-back direction and the left-right direction respectively through two sets of shaping devices (namely the Y shaping device 1 and the X shaping device 2) which are independent from each other, so that the shaping efficiency can be greatly improved compared with the traditional manual shaping mode.

Two points need to be explained here: 1) the positions of the Y shaping device 1 and the X shaping device 2 can be exchanged according to actual conditions, namely the X shaping device 2 is arranged in the previous process of the Y shaping device 1; 2) the movement speeds and the movement limit positions of the Y shaping device 1 and the X shaping device 2 can be preset according to actual conditions, so that the size consistency of the orthopedic top cover can be improved, and the subsequent assembly precision and welding quality can be further ensured.

The structure of the Y shaping device 1 and the X shaping device 2 will be described in detail below: the Y-shaper 1 is mainly composed of a number of first shaping blocks 11, a first power part 12, a second power part 13, etc. (as shown in fig. 3), and the number of the first shaping blocks 11 is set to 2, and the respective positions thereof correspond to the supports of the top cover. The first shaping block 11 is provided with a first shaping notch 111, and the size of the first shaping notch is matched with that of the bracket of the top cover. The first power part 12 drives the first shaping block 11 to move towards or away from each other along the left-right direction, so that the bracket of the top cover enters or leaves the first shaping notch 111. The second power portion 13 is disposed directly below the first power portion 12, and drives the first power portion 12 and the first shaping block 11 to move in the front-rear direction as a whole. The X-shaping device 2 is mainly composed of a second shaping block 21, a connecting transition 22, a third power portion 23, a fourth power portion 24, and the like (as shown in fig. 5).

The third power section 23 drives the connecting transition piece 22 in a forward-rearward direction. The fourth power portion 24 is disposed directly below the third power portion 23, and drives the third power portion 23 and the connecting transition piece 22 to move in the left-right direction as a whole. Thus, the Y shaping device 1 and the X shaping device 2 both have simple structural designs on the premise of meeting the functional requirements, and are favorable for production and manufacturing.

As known, copper and aluminum have certain toughness, and the elastic recovery phenomenon is easy to occur after the shaping is finished, so that the final shaping effect is influenced. In the actual reshaping process, the operator can refer to the following method: 1) the deformation in the direction of the shaping Y axis is that the shaping part pushes the bracket 2mm past the theoretical bracket position in the + Y direction, and then the shaping part pushes the bracket 2mm past the theoretical bracket position in the-Y direction; pushing the bracket by 1mm through the theoretical bracket position along the + Y direction by the shaping part, and then pushing the bracket by 1mm through the theoretical bracket position along the-Y direction by the shaping part; the shaping component pushes the stent to a theoretical stent position in the + Y direction. 2) The method for shaping the deformation in the X-axis direction is consistent with the method for shaping the deformation in the Y-axis direction, and comprises the following steps that a shaping part pushes a bracket 2mm past a theoretical bracket position in the + X direction, and then the shaping part pushes the bracket 2mm past the theoretical bracket position in the-X direction; pushing the bracket by 1mm through the theoretical bracket position along the + X direction by the shaping part, and then pushing the bracket by 1mm through the theoretical bracket position along the-X direction by the shaping part; the shaping component pushes the stent to a theoretical stent position in the + Y direction. After long-term experimental demonstration, after the top support is treated by the method, the elastic recovery phenomenon of the support can hardly occur at the later stage, and the support has better dimensional stability.

The fourth transmission block 243 is fixed right below the bearing plate 232. It should be noted that, in order to ensure high movement accuracy of the second shaping block 21, the third power unit 23 is additionally provided with a slide rail slider assembly 233. The slide rail and slide block assembly 233 is composed of a slide rail and a slide block. The slide block is detachably fixed below the connecting transition piece 22, and correspondingly, the slide rail is detachably fixed on the upper plane of the bearing plate 232.
