DETAILED DESCRIPTION

[0019] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings:

[0020] Specific implementation method 1: See Figure 1 The present embodiment is described. A brush special-shaped connector integrated pressing and forming die of the present embodiment comprises a die handle 1, a cylindrical pin 1 2, a hexagon socket screw 1 3, a cylindrical pin 2 4, an upper die seat 5, a backing plate 6, a fixing plate 7, a guide sleeve 8, a guide column 9, a hexagon socket screw 2 10, a hexagon socket screw 3 11, a cylindrical pin 3 12, left and right guide plates 13, a die 14, a lower die seat 15, a blanking punch 16, a first flanging punch 17, a second flanging punch 18, a limiting column 19, a first punching punch 20, a second punching punch 21, and a side blade 22.

[0021] The die handle 1 is fixed to the upper die base 5 by a cylindrical pin 2.
