As shown in fig. 1-2, is an embodiment provided by the present invention.

The embodiment of the utility model provides a wire feeding and drawing device, which comprises a power wheel 10, a first auxiliary wheel 11, a second auxiliary wheel 12 and a metal wire 20; the arc surfaces of the power wheel 10 and the arc surfaces of the first auxiliary wheel 11 and the second auxiliary wheel 12 are respectively in extrusion press fit, and the arc surfaces are in contact extrusion with each other; the metal wire 20 is located on the arc surface of the power wheel 10 and is tightly attached to the arc surface, and is located in the extrusion surfaces of the first auxiliary wheel 11 and the power wheel 10 and the extrusion surfaces of the second auxiliary wheel 12 and the power wheel 10, and the metal wire 20 between the two extrusion surfaces can be tensioned and attached to the arc surface of the power wheel 10. Compared with a single rotating wheel, the reciprocating movement of sending and withdrawing can be achieved only by releasing and rolling up the threading steel wire, and mechanical fatigue is not easy to accumulate (namely, the material or part gradually generates local permanent accumulation damage at one or more positions under the action of cyclic stress and strain and generates cracks or sudden fracture after a certain number of cycles).

Referring to fig. 1, the relative positions of the first auxiliary wheel 11 and the second auxiliary wheel 12 with the power wheel 10 are adjusted, so that the length of the metal wire 20 clinging to the arc surface of the power wheel 10 can be adjusted, and the bending degree of the metal wire 20 can be changed; in the state of forward rotation or reverse rotation of the power wheel 10, the wire 20 can move in a pinch manner by the power wheel 10 and the first auxiliary wheel 11, and the power wheel 10 and the second auxiliary wheel 12 in cooperation with each other, so that the wire 20 moves in a tangential reciprocating manner on the pressing surfaces between the power wheel 10 and the first auxiliary wheel 11, and between the power wheel 10 and the second auxiliary wheel 12.

Referring to fig. 2, the device further comprises a bottom plate 3 and a power motor 4, wherein the power wheel 10, a first auxiliary wheel 11 and a second auxiliary wheel 12 are fixed on one surface of the bottom plate 3, the power motor 4 is fixed on the other surface of the bottom plate 3, and the power motor 4 is arranged corresponding to the power wheel 10 at the position where the power wheel 10 is installed on the bottom plate 3, connected with the power wheel 10 and used for driving the power wheel 10 to rotate.

The device further comprises a first guide pipe 21 and a second guide pipe 22, both of which are fixed on the bottom plate 3 and are coplanar with the power wheel 10, wherein the first guide pipe 21 and the second guide pipe 22 are arc-shaped, referring to fig. 1, one port of the first guide pipe 21 faces the center of the tangent position of the power wheel 10 and the first auxiliary wheel 11, the other port faces the side edge of the bottom plate 3 close to the first auxiliary wheel 11, one port of the second guide pipe 22 faces the center of the tangent position of the power wheel 10 and the second auxiliary wheel 12, and the other port faces the direction consistent with the setting direction of the first guide pipe 21.

In this way, the wire 20 can sequentially move along the first guide tube 21, the tangent position of the power wheel 10 and the first auxiliary wheel 11, the arc surface of the power wheel 10, and the tangent position of the power wheel 10 and the second auxiliary wheel 12, and pass through the second guide tube 22, thereby completing a complete moving path.

In order to allow the wire 20 to switch the moving direction in the vertical direction and to maximize the contact surface with the power wheel 10, the central axes of the first auxiliary wheel 11, the second auxiliary wheel 12 and the power wheel 10 are arranged on the same horizontal straight line, and the wire 20 is in a semicircular shape on the arc surface of the power wheel 10.

The first guide pipe 21 and the second guide pipe 22 made of aluminum alloy are selected, so that the weight of the device can be effectively reduced, and the whole device is lighter. Meanwhile, in order to reduce the situation that the metal wire 20 slides out of the arc surface of the power wheel 10, the first auxiliary wheel 11, the second auxiliary wheel 12 and the power wheel 10 are integrally cylindrical.

Further reducing the abrasion of the metal wire 20 in the moving process, and selecting rubber wheels as the first auxiliary wheel 11, the second auxiliary wheel 12 and the power wheel 10; meanwhile, if the material of the wheel surface of the first auxiliary wheel 11 and the second auxiliary wheel 12 is changed into silica gel, the extrusion deformation degree of the extrusion surface can be increased, the abrasion of the metal wire 20 is further reduced, and the deformation is increased, so that the sliding is not easy to occur.

In the selection of the material of the metal wire 20, it is preferable to select a nickel titanium alloy with memory property, and the good memory property of the nickel titanium alloy allows the metal wire 20 to keep a linear shape for a long time.
