Description

Technical Field

[0001] The utility model belongs to the technical field of stamping blanking equipment, in particular to a blanking device for stamping a cylindrical battery shell. Background Art

[0002] The cylindrical battery case is the outer shell of a cylindrical battery, usually made of steel or aluminum. It is not only a physical protective structure for the battery, but also plays an important role in heat dissipation and preventing internal short circuits in the battery. It is often stamped and shaped by stamping equipment combined with a mold, so special cylindrical stamping equipment is often required.

[0003] At present, when the existing stamping equipment is used, the metal sheet will generate a great adsorption force after being stamped into an electromagnetic shell with one end closed and the other end open, resulting in a close fit with the inner core of the mold, making it difficult to cut the material easily, which affects the work efficiency. The strong cutting method is also easy to damage the thinner shell and affect its production quality.

[0004] In order to solve the above problems, the present application proposes a blanking device for stamping a cylindrical battery shell. Utility Model Content

[0005] The purpose of the utility model is to provide a blanking device for stamping a cylindrical battery shell, which solves the problems raised in the above-mentioned background technology.

[0006] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0007] The utility model discloses a blanking device for stamping cylindrical battery shells, comprising: an equipment main body and a punching head; a storage box is provided in front of the equipment main body to collect battery shells, a die seat is provided inside the upper end of the equipment main body, a sleeve is installed through the cover plate above it, and the battery shell is pressed against when the punching head is recovered, so that the battery shells of the same group of stamped and formed are placed in the same position for convenient unified blanking processing; a guide rod and a spiral rod are respectively provided on both sides of the upper end of the cover plate, the spiral rod is meshed and connected with the outer side of the upper end of the sleeve, and is used to drive the sleeve to press down to discharge the battery shell from the bottom, and adjacent through grooves and positioning grooves are respectively opened inside the cover plate, and a transmission belt and a rotating wheel are respectively installed, and the transmission belt is meshed with the rotating wheel through the convex teeth on the outer side to drive the spiral rod to rotate.

[0008] Furthermore, a seat plate is provided at the bottom of the equipment body, which is used to install the top plate through the hydraulic column above so that it is docked with the bottom of the mold base.

[0009] Furthermore, a guide platform is provided at the front bottom of the device body for guiding the battery shell into the interior of the storage box.

[0010] Furthermore, a push plate is installed in the bottom area of ​​the equipment body through an electric telescoping device, which is used to release the support for the seat plate and make it rotate automatically when the top plate moves downward.

[0011] Furthermore, the inner through grooves of adjacent cover plates are interconnected, thereby achieving the effect of controlling the rotation of multiple rotating wheels at the same time.

[0012] Furthermore, there is a certain gap between the lower end of the sleeve and the stepped hole inside the mold base, which is used to support the metal sheet to position it and prevent it from deflecting.

[0013] Furthermore, one end of the seat plate is rotatably mounted on two side walls inside the equipment body.

[0014] The utility model has the following beneficial effects:

[0015] The utility model can automatically press the battery shell against the punch head when the punch head is moved out to fix it inside the die base, thereby preventing the punch head from dragging out and affecting the subsequent blanking operation. At the same time, it ensures that multiple workpieces being punched at the same time maintain the same position, which is convenient for unified blanking operation and prevents the battery shell from being placed in different positions and affecting the blanking efficiency. After this arrangement, the difficulty of blanking operation can be reduced to improve efficiency.

[0016] In addition, after the punch head is moved out, the through groove and the spiral rod are used to drive the sleeve to be pressed down, and the top plate is moved down together, and then the seat plate is automatically tilted to lower the battery shell that has been separated from the die base into the storage box for collection. After this arrangement, the unloading operation can be completed in a unified manner without worrying about material jamming. At the same time, the sleeve can also be used to support the edge of the metal sheet during the next set of stamping operations to prevent it from being misplaced and affecting the production quality.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Please refer to Figures 1-5 As shown in the figure, the present utility model is a blanking device for stamping cylindrical battery cases, including: an equipment main body 1 and a stamping head 3; a storage box 2 is provided in front of the equipment main body 1 to collect battery cases, and a die base 4 is provided inside the upper end of the equipment main body 1. A sleeve 8 is installed through a cover plate 9 above it to hold the battery case when the stamping head 3 is retracted, so that the battery cases formed by the same group of stamping are placed in the same position for convenient unified blanking treatment;

[0029] On both sides of the upper end of the cover plate 9, a guide rod 11 and a screw rod 12 are respectively provided. The screw rod 12 is meshed and connected to the outer side of the upper end of the sleeve 8 to drive the sleeve 8 to press down to discharge the battery case from below. Adjacent through grooves 14 and positioning grooves 15 are respectively opened inside the cover plate 9, and a transmission belt 16 and a rotating wheel 13 are respectively installed. The transmission belt 16 is meshed with the rotating wheel 13 through the convex teeth 17 on the outside to drive the screw rod 12 to rotate;

[0030] The present embodiment provides a cylindrical battery shell stamping device that can quickly unload materials. After a plurality of battery shells are limited to a uniform position by the sleeve 8, the spiral rod 12 drives it to move downward to push the battery shells downward, and the materials are unloaded uniformly from the bottom of the mold base 4 and stored inside the storage box 2. In addition, when placing metal sheets, the sleeve 8 can be used to support their edge position to fix them, so as to prevent deflection during the stamping operation and ensure product production quality.

[0031] Among them, a seat plate 5 is provided at the bottom of the equipment body 1, which is used to install the top plate 6 through the hydraulic column above so that it is docked with the bottom of the mold base 4. The hydraulic column is used to drive the top plate 6 to move downward at the same time when the sleeve 8 is pressed down.

[0032] Among them, a guide platform 7 is provided at the bottom front position of the device body 1, which is used to guide the battery shell into the interior of the storage box 2, which is convenient for subsequent transportation and other processes, and at the same time reduces the height difference of the product to prevent bumps and damages.

[0033] Among them, a push plate 10 is installed in the bottom area of ​​the equipment body 1 through an electric telescoping device, which is used to release the support of the seat plate 5 when the top plate 6 moves down to make it rotate automatically, so that the battery shell tilts and automatically falls to achieve the effect of unloading.

[0034] The inner through slots 14 of adjacent cover plates 9 are connected to each other, so as to achieve the effect of controlling the rotation of multiple rotating wheels 13 at the same time.

[0035] Among them, there is a certain gap between the lower end of the sleeve 8 and the stepped hole inside the mold base 4, which is used to hold the metal sheet in place to prevent it from shifting, achieving the effect of one thing for multiple uses, enriching the function of the equipment and improving the use effect.

[0036] One end of the seat plate 5 is rotatably mounted on the inner side walls of the equipment body 1 , and automatically rotates and tilts after the support at the bottom is released.

[0037] It can be understood that the utility model can limit multiple products to a uniform position after the stamping operation, and simultaneously push them downward for unloading. The operation is simple and efficient. The sleeve 8 is also used to support the metal sheet before stamping, so that it is positioned in a predetermined position to prevent deviation, thereby ensuring the quality of the products produced.

[0038] A specific application of the operation process of this embodiment is as follows: when in use, first use the lower end portion of the sleeve 8 to press against the formed battery shell to prevent it from being carried away by the punch head 3 and causing multiple battery shells to be placed in different positions. Then, the outer convex teeth 17 of the transmission belt 16 are engaged with the rotating wheel 13 to drive the sleeve 8 to press down and push the battery shell downward through the spiral rod 12. At this time, the top plate 6 moves down with it. When the battery shell is separated from the die base 4, the push plate 10 is withdrawn to make the seat plate 5 automatically tilted, so that multiple battery shells can be lowered together into the internal storage of the storage box 2. Then, the sleeve 8 is recovered to the predetermined position and fed by a robot of an external device. At this time, the sleeve 8 is also used to press against the edge position of the metal sheet to prevent it from being offset during the stamping operation, thereby ensuring the production quality of the battery shell.
