[0056] During bending, the front end of the longitudinal filament passes through the positioning slot and the first positioning gap. The operator pushes one end of the bending head along the guide groove by manual, pneumatic or electric driving mode. During the movement, the other end of the bending head bends the end of each longitudinal filament in sequence, thereby integrating the welding and bending functions in the same welding tool, thereby eliminating the trouble of separate processing by multiple devices, and further improving the processing efficiency of the metal filaments.

[0057] In this embodiment, the bending head is L-shaped, and the end of the L-shaped bending head is located in the guide groove. The guide seat is parallel to the front surface of the front end positioning seat to orient and angle-bend each metal filament. In order to realize bending at different angles, the operator can adjust the length of the bending head to control the bending angle.

[0058] Meanwhile, a support seat 24 can be arranged between the guide seat and the front end positioning seat, the guide seat and the support seat are both in the shape of a long strip, the support seat is located at the inner side of the bent head end, the top surface of the support seat is in contact with the bottom surface of the bent head, so that the bent head can move stably in the guide groove.

[0059] In addition, in order to realize the shearing of the metal wire, so that the length of the metal wire is consistent, a wire shearing device (not shown in the figure) can be arranged on the rear end positioning seat, the shearing device can be fixed to the surface of the rear end positioning seat, the cutting edge of the shearing device can be flush with the surface of the wire positioning member on one side, when cutting, the cutting edge can move vertically under the driving of manual, pneumatic, electric and other driving modes, so as to cut the metal wire below.

[0060] In order to realize the limiting of the rear end of the longitudinal wire, so that the rear ends of the plurality of longitudinal wires are flush, the rear end positioning assembly further comprises a baffle, the baffle is arranged at the rear side of the rear end positioning seat and is fixedly connected with the rear end positioning seat, and the front side of the rear end positioning seat is provided with the wire positioning member.
