[0035] First embodiment

[0036] Reference Figures 1 to 3The present embodiment discloses a chamfering device for a tab, comprising: a base 4, a tool holder 1, a clamping plate 3, a tool 2 and a mold 5. The tool holder 1 and the base 4 are arranged relative to each other in the up-down direction, and the tool holder 1 and the base 4 are arranged at intervals. The tool holder 1 is slidably connected to the base 4 so that the tool holder 1 can move up and down relative to the base 4 under the action of an external force. A through hole for the tool 2 to pass through is provided on the clamping plate 3, and the clamping plate 3 is arranged between the base 4 and the tool holder 1. As can be seen from the accompanying drawings, the upper surface of the clamping plate 3 is arranged at intervals with the tool holder 1, and the lower surface is arranged relative to the base 4, but the clamping plate 3 is movably connected to the tool holder 1 in the up-down direction, so that the clamping plate 3 can cooperate with the base 4 to clamp the workpiece.

[0037] The upper end of the tool 2 is fixed on the tool holder 1, so that the tool 2 as a whole can move up and down synchronously with the tool holder 1. A through hole is penetrated at the lower end of the tool 2. The mold 5 is installed on the base 4. The tool 2 and the mold 5 are arranged relative to each other.

[0038] The cross section of the tool 2 is a pentagon, and the cross section of the tool 2 is composed of a rectangle and an isosceles triangle, wherein the base of the isosceles triangle coincides with one of the sides of the rectangle.

[0039] The die 5 is provided with a punching groove 50 , the cross section of which is the same as the cross section of the tool 2 , so that the tool 2 can be inserted into the punching groove 50 .

[0040] Compared with the existing rectangular cross-section tool 2, the cross-section of the tool 2 in this embodiment is based on the existing tool 2 by cutting off two right-angled parts, so that the existing tool 2 forms a pentagonal cross-section, so that chamfering can be achieved during the process of stamping and shearing the pole ears, the processing process is more convenient, and the process of shearing the rectangular pole ears again is omitted.

[0041] Reference Figure 2 and Figure 3 In this embodiment, a mounting groove 42 is provided on one side of the base 4 close to the clamping plate 3, and the mold 5 is embedded in the mounting groove 42. The depth of the mounting groove 42 is the same as the thickness of the mold 5 in the first straight line direction, so that the surface of the base 4 close to the knife seat 1 and the surface of the mold 5 close to the knife seat 1 are coplanar. If the mold 5 protrudes upward from the upper surface of the base 4, the tab may collide with the mold 5 during transportation, resulting in bending and the like. The coplanarity of the upper surfaces of the base 4 and the mold 5 makes the lower surface of the tab raw material 100 always fit the base 4, and the above-mentioned bending phenomenon will not occur.

[0042] In this embodiment, the mold 5 is formed by splicing a first mold 51 and a second mold 52. The first mold 51 is provided with a first sub-groove 53, and the second mold 52 is provided with a second sub-groove 54. When the first mold 51 and the second mold 52 are spliced ​​to form the mold 5, the first sub-groove 53 and the second sub-groove 54 are connected to form a stamping groove 50. In this embodiment, the mold 5 is not integrally formed, but is formed by splicing the first mold 51 and the second mold 52 in the installation groove 42. When one of the first mold 51 and the second mold 52 is damaged, only the damaged one needs to be replaced, saving resources.

[0052] Before cutting, the staff uses the first displacement assembly 8 and the second displacement assembly 9 to adjust the positions of all components on the base 4 relative to other processes in the factory.

[0053] The working process of this embodiment:

[0054] The feeding table 73 conveys the tab raw material 100 to the base 4, and the first cutter 61 in the cutting assembly 6 cuts the tab raw material 100 together with the second cutter 62 under the drive of the cutting power member 63, and then the knife seat 1 moves downward under the drive of the power assembly 72, driving the knife 2 and the clamping plate 3 on the knife seat 1 to approach the base 4. When the knife seat 1 moves down to a certain position, the clamping plate 3 first approaches the base 4 and clamps the tab raw material 100 with the base 4. As the knife seat 1 continues to move downward, the knife seat 1 compresses the reciprocating spring 13, so that the clamping plate 3 and the base 4 are further clamped, and the knife 2 gradually enters the stamping groove 50 to stamp and shear the tab raw material 100.

[0055] After shearing, the knife seat 1 moves upward to drive the knife 2 and the clamping plate 3 to move upward, so that the knife 2 and the clamping plate 3 are separated from the base 4.
