[0019] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments.

[0020] Embodiment 1: refer to Figures 1-5The utility model provides a kind of big cylindrical battery negative electrode end cover processing device, including pedestal 1, the top side of pedestal 1 is provided with telescopic component 2, one end bottom of telescopic component 2 is connected with pressure head 3, the top middle of pedestal 1 is provided with base 4, base 4 top middle is equipped with placing groove 5, adjusting mechanism is provided in placing groove 5, pneumatic telescopic rod 6 is provided on the base 4 of placing groove 5 two sides, the elongated rod of two pneumatic telescopic rods 6 is all through placing groove 5 and clamping end cover 7, the part area of base 4 with placing groove 5 is set as arc, the elongated rod of two pneumatic telescopic rods 6 is all installed with buffer block 14, two buffer blocks 14 are all set as arc shape.

[0021] after the end cover to be processed is placed in placing groove 5, the end cover 7 is clamped and positioned by two pneumatic telescopic rods 6 in combination with two buffer blocks 14, start hydraulic assembly 2, the extrusion forming process of telescopic component 2 with pressure head 3 to end cover 7 makes the positioning difficulty of end cover 7 relative to pressure head 3 drop, so that the quality of end cover after forming is improved, and the edge of end cover 7 is contacted with the edge of buffer block 14 outside the elongated rod of two pneumatic telescopic rods 6 in the process of reset movement of pressure head 3 after the combination of pressure head 3 and placing groove 5 makes end cover after forming, so that end cover 7 can fall off from pressure head 3, so that end cover 3 stays in placing groove, so that the difficulty of taking down end cover 7 drops.

[0022] In example 2, the end cover 7 is taken down from the pressure head 3 and stays in the placing groove 5 in example 1, because the surface of the end cover 7 is smooth, it is difficult to take out the end cover 7 from the placing groove 5, and on the basis of example 1, reference is made to Figures 1-5 The adjusting mechanism includes a groove 8 opened in one side of the base 4, the groove 8 is in communication with the placing groove 5, the groove 8 is installed with a stopper 9, the stopper 9 is slidably provided with a moving rod 10, one end of the moving rod 10 is installed with a placing disc 11, the bottom of the placing disc 11 is provided with an elastic member 12, one end of the elastic member 12 is connected to the stopper 9, the elastic member 12 is set as a cylindrical spring, the elastic member 12 is sleeved on the moving rod 10, and the moving rod 10 is installed with a clamping block 13.

[0023] On the basis of example 1, after the end cover 7 stays in the placing groove 5, start two pneumatic telescopic rods 6, so that two buffer blocks 14 are attached to the edge of placing groove 5, so that the elastic force of elastic member 12 lifts placing disc 11, so that placing disc 11 takes away end cover 7 from placing groove 5, so that the difficulty of taking out end cover 7 drops.
