Then they move away from each other and release the wire material.

[0033] The upper clamping wheel assembly 13 also includes an upper mounting block 133, an upper connecting post 134, an upper spring limiting post 135, an upper limit post 136, and an upper spring 137. The upper mounting block 133 is provided with an upper spring limiting groove 133a. The upper connecting post 134 passes through the upper spring limiting groove 133a and its upper and lower ends are respectively connected to the upper follower wheel 131 and the upper clamping head 132.

The upper connecting post 134 is provided with a waist-shaped hole 134a along its length direction. The upper mounting block 133 is fixed with an upper limit post 136 passing through the waist-shaped hole 133a.

[0034] The lower clamping wheel assembly 14 also includes a lower mounting block 143, a lower connecting post 144, a lower spring limiting post 145, a lower limiting post 146, and a lower spring 147. The lower mounting block 143 is provided with a lower spring limiting groove 143a. The lower connecting post 144 passes through the lower spring limiting groove 143a and its upper and lower ends are respectively connected to the lower follower wheel 141 and the lower clamping head 142. The lower spring limiting post 145 is fixed perpendicularly to the lower connecting post 144 and is pressed onto the lower spring 147 installed in the lower spring limiting groove 143a. The lower connecting post 144 is provided with an oblong hole along its length direction. The lower mounting block 143 is fixed with a lower limiting post 146 passing through the oblong hole.

[0035] An upper protrusion 138 is fixedly provided on the back of the upper mounting block 133. The top surface and the rear side surface of the upper protrusion 138 are respectively connected to a first guide wheel 1391 and a second guide wheel 1392.

[0038] The wire material passing mechanism 2 includes a straight inlet pipe 21 and a straight outlet pipe 22 located on both sides of the cam clamping and feeding mechanism.

[0039] When the high-speed traction feeding device disclosed in this embodiment of the invention is working, the servo motor drives the synchronous belt to rotate, thereby driving multiple upper clamping wheel sets 13 to be arranged around the upper track 11 and running against the upper track 11, and multiple lower clamping wheel sets 14 to be arranged around the lower track 12 and running against the lower track 12. When the upper follower wheel 131 runs against the upper plane cam structure and the lower follower wheel 141 runs against the lower plane cam structure, due to the structure of the plane cam structure itself, the upper clamping head 132 and the lower clamping head 142 approach each other and synchronously clamp the wire material coming out of the straight inlet tube 21 and move. Then they move away from each other and synchronously release the wire material and move. The wire material is moved out of the straight outlet tube 22, thus realizing rapid traction feeding.

[0040] Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
