Embodiment 1

[0016] Such as figure 1 As shown, the guide wire cam of the high-speed winding machine is used on the 16-head winding head. The length of the guide wire cam is 2050mm, the diameter is 64mm, and the working speed is 6500rpm. Including the guide wire cam body 1 and the guide wire groove 2 provided on the surface of the guide wire cam body 1, a hole 3 that does not penetrate the guide wire cam is respectively provided on the surface of the guide wire cam body 1 at the two ends of the guide wire cam, and the diameter of the hole 3 is 5mm, the depth of hole 3 is 7mm, the hole 3 on the left is 54.4mm away from the left end, the hole 3 on the right is 51.2mm away from the right end, the phase angle of the left and right holes 3 is 0°, the material of guide wire cam body 1 is structural steel, and the guide wire cam body 1 is made of structural steel. The curve fitting function for rounding at the intersection of thread groove 2 is: y=0.00152832x 2 , x 0 =12.312,y 0 =2.27, α=20°18′...

Embodiment 2

[0021] Such as image 3 As shown, the difference from Embodiment 1 is that the working speed of the guide wire cam is 8000rpm, the diameter of the hole 3 is 7mm, the depth of the hole 3 is 10mm, the distance between the hole 3 on the left side is 35.22mm from the left end, and the hole 3 on the right side is provided with Two, respectively 38.52mm and 44.36mm away from the right end, and the three-phase angle of the left and right holes is 90°.

Embodiment 3

[0023] Such as Figure 4 As shown, the difference from Embodiment 1 is that the diameter of the guide wire cam is 74 mm, the working speed is 7000 rpm, the diameter of the hole 3 is 6 mm, and the depth of the hole 3 is 8 mm. The natural frequency and corresponding rotational speed under φ74 are shown in Table 2:

[0024]

[0025] There are two holes 3 on the left side, 49.0mm and 53.3mm away from the left end respectively, and the hole 3 on the right side is 38.9mm away from the right end, and the angle between the left and right holes 3 is 0°.

Abstract

The invention discloses a yarn guide cam of a high-speed winding machine. The yarn guide cam comprises a yarn guide cam body and a yarn guiding groove formed in the surface of the yarn guide cam body, multiple holes which do not penetrate through the yarn guiding cam are formed in the positions, close to the two ends of the yarn guiding cam, of the surface of the yarn guide cam body respectively, the yarn guiding cam is specially used for the high-speed winding machine with 16 winding heads, wherein the rotation speed of the high-speed winding machine is 6500-8000 rpm. The section of the special position of the yarn guiding cam body is changed, mass distribution is changed, harmful vibration is reduced, and the yarn guide cam is particularly suitable for high-speed winding machine with the 16 winding heads, wherein the rotation speed of the high-speed winding machine is 6500-8000 rpm.

Description

technical field [0001] The invention relates to the field of spinning equipment, in particular to a high-speed winding machine guide wire cam. Background technique [0002] Guide wire cams are used in the winding mechanisms of two-for-one twisters, doubling machines, winders, draft-twisting machines, and elastic yarn machines. The guide wire cam is the key component of these machines. The general guide wire cam is die-cast from the same material with uniform quality, but with such a structural power distribution, the guide wire cam will vibrate during operation, and even harmful vibration will increase Big. Contents of the invention [0003] The main technical problem to be solved by the present invention is to provide a guide wire cam specially used for high-speed winding machines which effectively reduces harmful vibrations. [0004] The technical solution adopted by the present invention to solve its technical problems is: the guide wire cam of the high-speed winding ...
