Description

Technical Field

[0001] This utility model relates to the field of cylindrical battery processing technology, specifically a special mold for stamping and forming a cylindrical battery steel shell. Background Technology

[0002] Cylindrical battery steel casing is a structural component that protects the battery core. When processing cylindrical battery steel casing, a mold is needed to stamp the circular workpiece into shape. After stamping, the formed battery steel casing needs to be placed in a grinding device, and the upper opening of the battery steel casing is ground by the grinding device. Existing stamping molds have complex structures and can only process and form the casing. They cannot be used in conjunction with the grinding device. Therefore, the processing speed of battery steel casing is slow and inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a special mold for stamping cylindrical battery steel shells. The mold has a simple structure and is easy to operate. Multiple workpieces can be processed at the same time using this mold. Moreover, the mold can be used in conjunction with a grinding device to make the processing of cylindrical battery steel shells faster and improve processing efficiency, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a special die for stamping cylindrical battery steel shells, comprising a raised letter support platform, a support frame fixed on the upper surface of the raised letter support platform, two sliding grooves on the support frame, sliding rails slidably connected inside the two sliding grooves, a sliding seat fixed between the upper ends of the two sliding rails, a left and right driving component for driving the sliding left and right sliding at one end of the lower surface of the sliding seat, a rotating support platform rotatably connected to the upper surface of the sliding seat, a servo motor for driving the rotating support platform to rotate at the center of the lower surface of the sliding seat, four telescopic electric cylinders evenly fixed on the rotating support platform, a lower die fixed between the telescopic ends of the four telescopic electric cylinders, a die hole evenly provided on the lower die, with no less than three sets of die holes, a die column corresponding to each die hole on the upper surface of the rotating support platform, the upper end of the die column located inside the die hole, a stamping driving component provided at the middle of the left end of the raised letter support platform, and a stamping upper die column corresponding to the die hole on the stamping driving component.

[0005] Furthermore, the stamping drive includes an L-shaped support fixed to the convex support platform. A stamping cylinder is fixed to the upper end of the L-shaped support. The extension of the stamping cylinder can drive the upper stamping die column to move downward. The upper stamping die column stamps the workpiece at the upper end of the mold hole, and then the mold hole, mold column and upper stamping die column extrude the workpiece into shape.

[0006] Furthermore, the left and right driving components include a support fixed to one side of the sliding seat. One side of the support is connected to an adjusting stud via a bearing. The adjusting stud is connected to the support frame via a threaded connection. One side of the support is provided with a servo motor that drives the adjusting stud to rotate. The rotation of the servo motor can drive the adjusting stud to rotate, thereby driving the sliding seat to slide left and right. This allows the support platform and the lower mold to be rotated and moved to the left or right end of the support frame, thereby adjusting the position of the front and rear mold holes. The support platform and the lower mold can also be moved to the bottom of the external grinding device, whereby the external grinding device grinds the upper opening of the cylindrical battery steel shell.

[0007] Furthermore, each group of mold holes has the same number of holes, and the mold holes in each group are evenly distributed around the center of the lower mold. A workpiece positioning groove is set at the upper end of the mold hole, which can be used to position the workpiece. The fact that each group of mold holes has the same number of holes and is evenly distributed ensures that the servo motor rotates at the same angle each time, making it easier to control the device.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: This special die for stamping and forming cylindrical battery steel shells has the following advantages: 1. This utility model uses a servo motor to rotate an adjusting stud, which in turn drives the sliding seat to slide left and right. This allows the support platform and lower mold to be moved to the left or right end of the support frame, thereby adjusting the position of the front and rear mold holes. It can also move the rotating support platform and lower mold to the bottom of an external grinding device, which then grinds the upper opening of the cylindrical battery steel shell.

[0009] 2. This utility model uses a stamping upper die post to stamp the workpiece at the upper end of the die hole, and then the die hole, die post and stamping upper die post extrude the workpiece into shape. The servo motor can rotate at the same angle every time by using a set of die holes of the same number and evenly distributed, which makes the control of the device more convenient.

[0010] 3. This utility model has a simple structure and is easy to operate. Multiple workpieces can be processed at once using this mold. Moreover, the mold can be used in conjunction with a grinding device, which makes the processing of cylindrical battery steel shells faster and improves processing efficiency.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-4This utility model provides a technical solution: a special mold for stamping and forming a cylindrical battery steel shell, including a raised support platform 1, a support frame 2 fixed on the upper surface of the raised support platform 1, two sliding grooves 13 provided on the support frame 2, and sliding rails 11 slidably connected inside the two sliding grooves 13. A sliding seat 12 is fixed between the upper ends of the two sliding rails 11. A left and right driving member 4 is provided at one end of the lower surface of the sliding seat 12 to drive it to slide left and right. A rotating support platform 5 is rotatably connected on the upper surface of the sliding seat 12. A servo motor 10 for driving the rotating support platform 5 to rotate is provided at the center of the lower surface of the sliding seat 12. Four telescopic components are evenly fixed on the rotating support platform 5. Electric cylinders 3, four telescopic electric cylinders 3 are connected by a lower mold 7, which has mold holes evenly distributed on it, with no fewer than three sets of mold holes. The upper surface of the rotating support platform 5 is provided with mold pillars 6 corresponding to the mold holes, with the upper ends of the mold pillars 6 located inside the mold holes. A stamping drive component 8 is located in the middle of the left end of the convex support platform 1. The stamping drive component 8 has upper stamping die pillars 9 corresponding to the mold holes. The stamping drive component 8 includes an L-shaped support 82 fixed to the convex support platform 1. A stamping cylinder 81 is fixed to the upper end of the L-shaped support 82. The extension of the stamping cylinder 81 can drive the upper stamping die pillars 9 to move downwards, thus pressing the workpiece at the upper end of the mold hole. The stamping process involves pressing the workpiece, which is then extruded and formed by the die holes, die pillars 6, and upper stamping die pillars 9. The left and right driving components 4 include a support 42 fixed to one side of the sliding seat 12. One side of the support 42 is connected to an adjusting stud 43 via a bearing. The adjusting stud 43 is connected to the support frame 2 via a threaded connection. One side of the support 42 is equipped with a servo motor 41 that drives the adjusting stud 43 to rotate. The rotation of the servo motor 41 drives the adjusting stud 43 to rotate, thereby causing the sliding seat 12 to slide left and right. This allows the support platform 5 and the lower die 7 to be moved to the left or right end of the support frame 2, thereby adjusting the position of the front and rear die holes. The support platform 5 and the lower die 7 can also be rotated. The mold 7 moves to the bottom of the external grinding device, which grinds the upper opening of the cylindrical battery steel shell. Each group of mold holes has the same number of holes, and the mold holes in each group are evenly distributed around the center of the lower mold 7. A workpiece positioning groove is set at the upper end of the mold hole, which can be used to position the workpiece. The equal number and even distribution of mold holes in each group can ensure that the servo motor 10 rotates at the same angle each time, making the control of the device more convenient. The mold has a simple structure and is easy to operate. Multiple workpieces can be processed at once using this mold. Moreover, this mold can be used in conjunction with the grinding device to make the processing of cylindrical battery steel shells faster and improve processing efficiency.

[0015] In use: The workpiece at the upper end of the die hole is stamped by the upper stamping post 9, and then the workpiece is extruded and formed by the die hole, the die post 6 and the upper stamping post 9. The servo motor 10 can rotate at the same angle every time by the same number of die holes in each group, which makes the control of the device more convenient. The rotation of the servo motor 41 can drive the adjusting stud 43 to rotate, thereby driving the sliding seat 12 to slide left and right. This allows the support table 5 and the lower die 7 to be moved to the left or right end of the support frame 2, thereby adjusting the position of the front and rear die holes. The support table 5 and the lower die 7 can also be moved to the bottom of the external grinding device, and the external grinding device can grind the upper opening of the cylindrical battery steel shell.

[0016] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
