[0002] The wire pressing device of the inverted wire drawing machine mainly includes a cylinder, a rotating arm and a wire pressing wheel. One end of the rotating arm is connected to the cylinder and the other end is connected to the wire pressing wheel. The outer wall of the wire pressing wheel presses the outer wall of the wire drawing drum. When the equipment is running, the wire pressing wheel makes the metal wire generate a certain friction force on the wire drawing drum to ensure the smooth progress of the drawing process.

In addition, since the crimping wheel wears quickly, it is often not pressed tightly when changing to a small-sized steel wire, and is easy to fall and scratch. Therefore, how to make the crimping wheel sensitively and stably press steel wires of various specifications becomes a problem that needs to be solved. Utility Model Content

[0021] Please refer to Figure 2 and Figure 3 A wire pressing wheel 100 for an inverted wire drawing machine includes a roller 1, a first bearing 2, a second bearing 3 and a wheel axle 4.

[0022] The side of the roller 1 is slightly inclined at a first angle a, and the bottom surface of the roller 1 is larger than the cone of the top surface. After the side of the roller 1 is slightly inclined in this way, even if the roller 1 is worn, it can still effectively prevent the steel wire from falling. The bottom surface of the roller 1 is provided with an R-shaped chamfer 10. This can prevent the roller 1 from scratching the steel wire. The top surface of the roller 1 is provided with a first bearing hole 11, the bottom surface of the roller 1 is provided with a second bearing hole 12, and the roller 1 is also provided with an axle hole 13 that passes through the first bearing hole 11 and the second bearing hole 12.

[0023] The first bearing 2 is integrally embedded and fitted in the first bearing hole 11 , and the second bearing 3 is integrally embedded and fitted in the second bearing hole 12 .

[0024] The axle 4 is inserted through the inner ring of the first bearing 2 , the axle hole 13 and the inner ring of the second bearing 3 in sequence.

[0025] Optionally, the first angle a is 2-10 degrees. Such a small angle inclination can not only ensure that the upper and lower parts of the roller can effectively press the steel wire, but also prevent the steel wire from falling downwards.

[0026] Optionally, the first bearing 2 and the second bearing 3 are bearings of the same specification, which facilitates the purchase and maintenance of the bearings.

[0027] Preferably, the first bearing 2 and the second bearing 3 are both 6305 bearings. The load of 6305 bearings is greater than that of 6205 bearings, which facilitates the stable rotation of the roller.

[0028] Optionally, the thickness of the first bearing 2 is not greater than the depth of the first bearing hole 11, and the thickness of the second bearing 3 is not greater than the depth of the second bearing hole 12. This makes it easier to install the bearing inside the roller and reduces interference during rotation.

[0029] Optionally, the outer diameter of the first bearing 2 is equal to the inner diameter of the first bearing hole 11, and the outer diameter of the second bearing 2 is equal to the inner diameter of the second bearing hole 12. This arrangement facilitates the two bearings to be stably fitted and fixed in the roller.

[0030] Optionally, the central axis of the roller 1 coincides with the central axis of the axle 4. This arrangement makes the rotation of the roller more stable.

[0031] Optionally, the inner diameter of the axle hole 13 is larger than the outer diameter of the axle 4. This facilitates the relative rotation of the axle and the roller without interference.

[0032] Optionally, the outer diameter of the axle 4 is equal to the inner diameter of the first bearing 2 and the inner diameter of the second bearing 3. This arrangement facilitates the axle to be firmly and stably inserted into the inner rings of the first bearing and the second bearing.

[0033] The wire pressing wheel for the inverted wire drawing machine of the utility model not only rotates sensitively and smoothly and presses the wire very stably, and even if the steel wire is replaced with a small-sized steel wire, the steel wire is not easy to fall off, and it can also effectively prevent the roller from scratching the steel wire, and also prolong the service life of the wire pressing wheel.
