The workpiece 6 includes a terminal 61, and a pin 63 connected to the lead 62 is arranged at one end of the terminal 61.
[0024] In a preferred embodiment of the present invention, the bending mechanism 3 includes a swing arm 34 swingably arranged on the side of the L-shaped mounting plate 1. The swing arm 34 is swingably arranged on the displacement mechanism through the bending swing mechanism 33, and the displacement mechanism is a bending transverse cylinder 32 movably arranged on one side of the mounting plate 1. At least one end of the swing arm 34 close to the bending limit clamp 2 is provided with a bending clamp 35 that can relatively open and close and clamp the end 61, and the end of the clamping end of the bending clamp 35 faces the pivot axis of the swing arm 34.
[0025] In a preferred embodiment of the present invention, the bending limit clamp 2 is movably arranged on the mounting plate 1 through the displacement cylinder 11 and the connecting plate 20, the bending limit mounting plate 21 and the propulsion cylinder 22. The bending limit clamp 2 can perform relative reciprocating motions in the front, back, left and right directions relative to the bending jaw 35 under the drive of the displacement cylinder 11 and the propulsion cylinder 22. The bending limit clamp 2 also includes at least one pair of positioning clamps 24 that can clamp relative to each other.
[0026] Furthermore, the displacement cylinder 11 drives the connection plate 20 provided on the displacement cylinder 11 to extend and retract forward and backward, the propulsion cylinder 22 provided on the connection plate 20 drives the positioning cylinder 23 provided on the propulsion cylinder 22 to extend and retract forward and backward, and the positioning cylinder 23 drives the positioning fixture 24 provided on the positioning cylinder 23 to open and close. A supporting groove matching the shape of the workpiece 6 is provided on one side of the positioning fixture 24. The supporting groove is provided with a support table for supporting the pin 63 in the workpiece 6; and a receiving groove for receiving the end 61 in the folded workpiece 6.
[0027] In a preferred embodiment of the present invention, the middle positioning fixture 4 includes a longitudinal support plate arranged on the mounting plate 1 and inserted into the lower part of the mounting plate 1, a middle clamping cylinder 42 is arranged under the longitudinal support plate, and a pair of middle positioning jaws 43 that can be relatively opened and closed are arranged at the bottom end of the middle clamping cylinder 42. The middle positioning jaws 43 can be reciprocated and opened and closed under the drive of the middle clamping cylinder 42 to clamp the middle part of the lead 62 of the workpiece 6.
