Description

Technical Field

[0001] The utility model belongs to the technical field of nickel sheet stamping, and in particular relates to a semi-finished nickel sheet stamping die. Background Art

[0002] Nickel sheets are conductors used to be fixed to battery conductors. Generally, a stamping die is used to punch nickel sheets off a nickel strip. The nickel strip is moved by a driving roller on the side of the impact device so that the nickel strip is located between the upper and lower dies. The upper and lower dies are then pushed together by a cylinder to punch the nickel sheet off. The nickel sheet needs to be briefly paused in conjunction with the stamping structure during the feeding process. If the position of the nickel sheet is offset, it is easy for the nickel sheet to overlap during extrusion, affecting the production quality of the nickel sheet. In addition, the nickel sheet is easily stuck in the groove of the lower die after stamping and needs to be cleaned manually. Utility Model Content

[0003] In view of the above technical problems, the utility model provides a semi-finished nickel sheet stamping die, in which the lower part of the stamping hole on the lower die is arranged in a trapezoidal shape to prevent the nickel sheet from being stuck inside the stamping hole, and tensioners are respectively installed on the left and right sides of the upper die to tension the nickel strip to prevent the nickel strip from being offset and folded during the stamping process.

[0004] The technical solution is as follows: a semi-finished nickel sheet stamping die, including a stamping bottom die, a through groove is opened on the inner upper part of the stamping bottom die, and an enlarged drop hole is opened on the inner lower part of the stamping bottom die. It is characterized in that a bottom collecting cover assembly is installed at the lower part of the stamping bottom die, a stamping punch is arranged at the upper part of the stamping bottom die, a reinforcing connecting seat is integrated at the upper part of the stamping punch, and spring tensioner assemblies are respectively installed on the left and right sides of the stamping punch.

[0005] Preferably, the bottom collecting hood assembly comprises a conical collecting hood, and side fixers are respectively provided on the left and right sides of the conical collecting hood, and a guide bag is glued to the lower part of the conical collecting hood.

[0006] Preferably, the spring tensioner assembly comprises a rubber contact column, the front and rear ends of the upper portion of the rubber contact column are respectively glued with an extended rotating rod, the upper left portion of the extended rotating rod is axially connected to a fixed ear plate, and the side surface of the extended rotating rod is axially connected to a tension spring.

[0007] Preferably, the conical collecting cover is arranged at the lower part of the stamping bottom die, and the inner lower part of the enlarged drop hole is connected to the inner side of the conical collecting cover.

[0008] Preferably, the side fixers are respectively bolted to the left and right sides of the lower part of the stamping bottom die, and the side fixers are respectively fitted to the left and right sides of the conical collecting cover.

[0009] Preferably, the fixing ear plates are provided in plurality, and are welded to the left and right sides of the reinforcing connecting seat in groups of two.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] In the utility model, the arrangement of the conical collecting cover, the side fixer, the guide bag and the enlarged drop hole is conducive to preventing the nickel sheets from being stuck on the inner side of the through groove, while collecting the nickel sheets and preventing them from falling to the outside of the collection box.

[0012] In the utility model, the arrangement of the rubber contact column, the extended rotating rod, the fixed ear plate and the tension spring is conducive to smoothing and tensioning the nickel strip, and preventing the nickel strip from being offset and overlapped during stamping.

[0018] The utility model is further described below in conjunction with the accompanying drawings:

[0019] Example:

[0020] As attached Figure 1 As shown, a semi-finished nickel sheet stamping die comprises a stamping bottom die 1, a through groove 2 is provided on the inner upper part of the stamping bottom die 1, an enlarged drop hole 3 is provided on the inner lower part of the stamping bottom die 1, and it is characterized in that a bottom collecting cover assembly 4 is installed on the lower part of the stamping bottom die 1, a stamping punch 5 is provided on the upper part of the stamping bottom die 1, a reinforcing connecting seat 6 is integrated on the upper part of the stamping punch 5, and spring tensioner assemblies 7 are respectively installed on the left and right sides of the stamping punch 5.

[0021] In the above embodiment, specifically, the side of the tension spring 74 away from the extending rotating rod 72 is axially connected to a rotating assembly, and the other end of the rotating assembly is respectively bolted to the four corners of the punch 5 .

[0022] How it works

[0023] The working principle of the utility model is as follows: first, the stamping bottom die 1 is fixed to the base of the stamping equipment, and the upper bolts of the strengthening connecting seat 6 are fixed to the lower part of the output rod of the cylinder. The driving assembly of the stamping equipment drives the nickel strip to move between the stamping bottom die 1 and the stamping punch 5, and then the cylinder pushes the stamping punch 5 to move downward. The lower part of the rubber contact column 71 first contacts the upper left and right sides of the nickel strip. As the stamping punch 5 continues to move, the rubber contact column 71 will smooth and tension the nickel strip. The stamping punch 5 and the through groove 2 cooperate with each other to cut the nickel strip. The cut nickel strip enters the inner side of the enlarged drop hole 3 and then falls downward, and falls into the collection box placed in advance at the lower part of the guide bag 43 through the conical collection cover 41 and the guide bag 43.

[0024] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
