Detailed Description

The invention will be further described with reference to the accompanying drawings and specific embodiments.

Example 1

The embodiment discloses a foot shearing device for a bridge rectifier, as shown in fig. 1 and 2, which includes a mold bearing base 1, a mold bearing base support 2 disposed on the mold bearing base 1, and a pneumatic motor support 4 connected to the mold bearing base support 2.

A groove is formed in the mold bearing base 1, and the mold 8 is placed in the groove and fixed through a fixing jackscrew 9. The die is used for placing the bridge rectifier of the pin to be cut.

Be equipped with pneumatic motor 5 on the pneumatic motor support 4, pneumatic motor 5 connects pneumatic push rod mobile jib 3, and pneumatic push rod telescopic link 6 is connected to 3 lower extremes of pneumatic push rod mobile jib. The lower end of the pneumatic push rod telescopic rod 6 is connected with a bridge rectifier fixing block 7, the pneumatic push rod main rod 3 is connected with a cutter support 10, and a cutter 11 is connected on the cutter support 10.

In this embodiment, the pneumatic motor 5, the main rod 3 of the pneumatic push rod, and the telescopic rod 6 of the pneumatic push rod form a driving system, and the fixed block 7 of the bridge rectifier, the cutter 11, and the cutter support 10 form a pin cutting system. The driving system is connected with the pin shearing system and used for driving the pin shearing system to shear the pins of the bridge rectifier.

In other embodiments, the driving system may also adopt another structure, such as a screw nut pair structure, the screw rod is connected to the pneumatic push rod main rod 3, the pneumatic push rod main rod 3 is connected to the pneumatic push rod telescopic rod 6, the motor drives the screw rod to rotate, and the rotation is converted into a linear motion through the cooperation of the screw rod and the nut, so that the electric pneumatic push rod main rod 3 and the pneumatic push rod telescopic rod 6 move.
