Detailed Description

In order that the present invention may be more readily and clearly understood, the following detailed description of the present invention is provided in connection with the accompanying drawings.

As shown in fig. 1 to 5, the present embodiment provides a motor casing side stamping die, which includes an upper die 1, a lower die 2, a lower pressing block 3, a lower pressing sleeve 4, a positioning column 5 and a stamping mechanism 6, wherein the upper die 1 of the present embodiment is driven by a nitrogen spring of a stamping die to be pressed, and the lower die 2 is fixed.

As shown in fig. 1, the lower pressing block 3 and the lower pressing sleeve 4 of the present embodiment are both fixedly connected to the upper die 1, the positioning column 5 and the punching mechanism 6 are fixed to the lower die 2, and the upper die 1 is used for driving the lower pressing block 3 and the lower pressing sleeve 4 to move downward.

As shown in fig. 1, the pressing sleeve 4 of the present embodiment is located above the positioning column 5, the motor casing is pressed down onto the positioning column 5 through the pressing sleeve 4, and a pressing hole 41 adapted to the top of the motor casing is formed at an end of the pressing sleeve 4. After the pressing down, the positioning column 5 is inserted into the motor casing, the pressing down sleeve 4 and the positioning column 5 are coaxially arranged, the coaxiality of the motor casing and the positioning column in the pressing down process is guaranteed, and the motor casing is prevented from generating axial displacement.

As shown in fig. 2, the four press-down blocks 3 of the present embodiment are used to drive the punching mechanisms 6 to punch the motor casing on the positioning column 5, the four punching mechanisms 6 are respectively arranged on a circle with the positioning column 5 as a center, and the distance between every two punching mechanisms 6 is equal. Four punching press mechanisms 6 evenly distributed are around the motor casing, carry out the punching press to the lateral wall of motor casing simultaneously, and radial to the motor casing carries on spacingly, has avoided the motor casing to produce the displacement in footpath.

As shown in fig. 3, 4 and 5, the punching mechanism 6 of the present embodiment includes a punching base 61, a slider 62 and a punch 63, the punching base 61 is fixed on the lower die 2, the slider 62 is slidably connected to the punching base 61, and the punch 63 is fixed on an end of the slider 62 facing the positioning column 5. One end of the sliding block 62 far away from the positioning column 5 is provided with a downward inclined slope 621, and the end of the lower pressing block 3 is provided with an inclined surface 31 which is matched with the slope 621 to slide. After the pressing, the inclined surface 31 of the pressing block 3 presses the sliding block 62 downwards along the slope 621 of the sliding block 62, so as to open the sliding block 62, and the sliding block 62 drives the punch 63 to move towards the positioning column 5, so as to punch the motor casing.
