Detailed Description
In order to better understand the purpose, structure and function of the present invention, the following description is made in detail with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, the tab punching device of the present invention includes a base 1, wherein the base 1 is used for placing and fixing a battery; the base 1 is provided with a movable shaping plate 3 and a movable punching pin 4, so that the shaping plate 3 flattens the pole ear of the battery, and the punching pin 4 penetrates through the shaping plate 3 and punches the pole ear. Thus, the punching needle 4 punches a hole for the tab while shaping the tab, so that the tab and the pole are riveted through the rivet.
In order to drive the punching needle 4 to lift, a movable transmission plate 2 is formed on the upper side of the base 1, and the punching needle 4 is fixedly connected to the transmission plate 2; the punching needle 4 moves to punch the polar lug along with the movement of the transmission plate 2.
A punching spring 5 is clamped between the shaping plate 3 and the transmission plate 2, and the punching spring 5 is used as a first elastic element and flexibly connected with the transmission plate 2 and the shaping plate 3; along with the movement of the transmission plate 2, the punching elastic element enables the shaping plate 3 to flatten the pole piece, and then the punching elastic element elastically contracts to enable the punching needle 4 to penetrate through the shaping plate 3 so as to punch a hole. For the convenience of installation, the punching spring 5 is sleeved outside the punching needle 4.
A shaping spring 6 is clamped between the base 1 and the shaping plate 3, and the shaping spring 6 is used as a second elastic element and flexibly connected with the base 1 and the shaping plate 3; along with the driving plate 2 approaching the tab, the shaping spring 6 contracts, and the shaping plate 3 flattens the tab; and the shaping spring 6 extends along with the distance of the transmission plate 2 from the lug to drive the shaping plate 3 to reset. Since the shaping plate 3 is required to be shaped first and then punched again by the punching pin 4, the elastic force of the punching spring 5 is greater than that of the shaping spring 6.
