The bending of the pin is completed through the forming assembly, wherein the first two times of bending of the pin are completed through the forming component, and the third time of bending of the pin is completed through the downward movement of the bending forming plate driven by the third forming cylinder. The forming part comprises a first forming cylinder which is linearly driven in the inner and outer directions and a second forming cylinder which is linearly driven in the left and right directions in a horizontal plane; according to the invention, the forming lifting seat is slidably arranged in the vertical groove of the forming sliding seat in the vertical direction as a supporting component, a spring is connected between the forming lifting seat and the inner side wall of the vertical groove, and the elastic force of the spring pushes the forming lifting seat upwards in a natural state; the lower part of the forming lifting seat is horizontally provided with a forming seat, and the bottom of the forming seat is vertically provided with a first column body and a second column body; the side parts of the first column body and the second column body are respectively and rotatably connected with a first bending rod and a second bending rod, a swinging groove is arranged between the first bending rod and the first column body, a through groove is arranged in the middle of the swinging groove, a connecting part between the second bending rod and the second column body is positioned in the through groove penetrating from the swinging groove, and the second bending rod can freely move in the swinging groove so as to leave a displacement space; the lower end surfaces of the first bending rod and the second bending rod are provided with annular clamping grooves which are concave inwards, and the inner diameter of each annular clamping groove is not smaller than the outer diameter of each pin; when the bending is performed, the first bending rod and the second bending rod are close to the right side of the long pin, so that the long pin slides into the circular clamping groove, the second bending rod firstly contacts the long pin, and bends the long pin against the rear side wall of the forming block in the leftward linear movement process; meanwhile, the first bending rod positioned on the right side of the second bending rod continuously presses the long pins at the back in the moving process so as to bend and maintain the pressure of the bent long pins, and the bent part of the long pins is tilted backwards while the second bending rod bends the long pins. The second bending rod after the first bending is completed moves to the left side of the forming block, and the first bending rod is attached to the rear side wall of the forming block; when the second bending is performed, the first bending rod and the second bending rod synchronously move forward in a straight line, the second bending rod is in an empty state, and the first bending rod bends the long pins against the left side wall of the forming block until the long pins extend outwards, so that the second bending is completed. After secondary bending of the long pin is completed, the first bending rod and the second bending rod need to return to the bending starting position so as to perform the next bending action, and the swing groove structure design of the second bending rod enables the groove wall to block and limit the second bending rod when the first bending is performed, and in the returning process, the second bending rod can slide along the idle position of the swing groove; therefore, when the first bending rod and the second bending rod move back to the right straight line along the rear side wall of the forming block, the second bending rod on the left side can be prevented from laterally pressing the long pin to cause the left part of the long pin to tilt. In addition, in the first bending process of the long pin, when the second molding cylinder drives the molding sliding seat to linearly move leftwards, the molding pulley which is rotatably arranged at the top of the molding lifting seat gradually slides into the guide cambered surface at the bottom of the molding guide block above the molding lifting seat, and correspondingly pushes the molding pulley to drive the molding lifting seat to gradually descend along with the continuous leftward sliding of the molding pulley, so that the pin bending pressing requirement is met. After three bending actions are completed, the lower end parts of the two bent pins of the capacitor are required to be cut off; after the capacitor on the jig completes three bending and forming actions at the forming mechanism, the turntable drives the jig to move to the pin cutting mechanism, and the tail ends of the capacitor pins are cut off through the pin cutting mechanism. The pin cutting mechanism comprises a pin pressing assembly and a pin cutting assembly, wherein the pin pressing assembly is used for pressing and fixing two pins of a capacitor before pin cutting, and the pins are moved when the pins are placed, so that the problem of uneven length of the pins is caused, and the quality of the pins is affected. According to the invention, the presser foot lifting seat is driven to move downwards through the presser foot cylinder, the presser foot lifting seat drives the presser foot to descend, the presser foot lifting seat is slidably arranged in the presser foot along the vertical direction, and the pre-pressing block pushed downwards through the spring presses the root parts of two pins of the capacitor in the jig outwards in advance while the presser foot cylinder descends along with the presser foot; when the press seat continues to descend, the press groove and the press plate at the bottom of the press seat respectively press the long pins and the short pins; meanwhile, one side of the presser foot lifting seat is also provided with the inductor, when the inductor descends along with the presser foot lifting seat, the inductor contacts the inductor seat arranged below the inductor seat, and when the inductor generates a contact signal, the presser foot lifting seat stops pressing down so as to prevent pins from being crushed.
