Description

The invention relates to the electrical industry and can be used for the manufacture of battery cases.

. A device for producing battery cases is known, comprising a first bending mechanism, a second bending mechanism, and a welding mechanism 11.

However, transporting the blanks between process positions is manually manually sacrificed.

The closest to the proposed technical essence and achievable results is a device for manufacturing battery cases, containing a fixed frame sequentially installed along the process and guideways, bending units, a punch first bending with a die and ejector, translational movement, welding and prikatno rollers and busbars LSI.

A disadvantage of the known device is that it does not provide the same assembly of the edges to be welded.

The purpose of the invention is to reduce the marriage.

The goal is achieved by the fact that in a device for manufacturing battery cases, containing a fixed frame and guides sequentially installed along the technological process, bending units, a first punch are flexible with a matrix and an ejector, a second punch are flexible with a console, a ejector with a pusher, a translational drive displacements, welding and stitching rollers and then coping tires, the second bending assembly additionally contains pressure rollers connected with a translational drive, one and From the vertical walls of the second punch are flexible, a flat spring is mounted, and the stitching rollers are located along the perimeter of the console, the extension of the second punch is flexible, one of the side rollers is located vertically, mounted on the console wall, which is an extension of the punch wall on which the flat spring is mounted, and shifted relative to the rest of the stitching rollers forward in the direction of the lower welding roller.

Figure 1 shows the proposed device, the overall view; in fig. 2 section aa in FIG. on fig.Z - section BB in figure 1; figure 4 is a section bb In figure 1; figure 5 is a section of GG in figure 1; figb is an example of proper assembly of the edges of the battery casing before the seam welding;

Fig. 7 illustrates an example of improperly assembling the edges of a battery case before welding.

The proposed device comprises a frame 1, guides 2, a punch 3 of the first bending, a matrix of the first bending 4 with an ejector 5, spring-loaded with a spring 6, a punch 7 of the second bending, a matrix of the second bending 8 with the ejector 9, spring-loaded with a spring 10, anvil 11 with a pneumatic actuator 12, pinch rollers 13 mounted on a plate 14 driven by a pneumatic actuator 15, a housing 16 with attached precise rollers 17-23 mounted on an axis 24, a flat spring 25, a lower 26 and an upper 27 welding rollers. The dies are driven by hydraulic actuators 2.8 and 29. The accumulator casing of the battery is moved from one technological position to another by means of chain conveyors.

30 and 31.

The device works as follows.

 Flat billet 32 from the loading position moves to the position of the first flexible conveyor 30. Hydraulic actuator 28 operates, the die 4 rises along with the billet and

0 is flexible. After the end of the first bending, the workpiece moves to the position of the second bend. The hydraulic actuator 29 operates. In this case, the spring 25 limits the movement

5 of the vertical wall of the housing, to which the horizontal is adjacent, is short on the shelf 33. Following this, the pneumatic actuator 15 is activated, the strip 14 of the roller 13 is lowered and presses to

A long horizontal shelf 34 of the body is flexible to the second punch. In this position with the help of conveyor

31, the workpiece is pushed into housing 16. At the same time, it interacts with its walls with rollers 17, 22 and

5 23 and only then a vertical wall with a short shelf is pressed by the roller 20. This is achieved by displacing the roller 20 by the amount L relative to the rollers 17.22 and 23.

0 From the housing 16, the workpiece leaves already assembled and goes to the welding position. Here, the upper welding roller is lowered, its rotation and welding current are turned on. The longitudinal seam is welded (shelf 33 is welded to shelf 34. and the finished housing falls, for example, onto a conveyor belt).

The proposed device for preparing battery cases ensures the same assembly of the edges of the battery housing being welded before the welding operation.
