Example Embodiment

[0027] Example 1
[0028] In a typical embodiment of the present invention, such as figure 1 As shown, this embodiment discloses a rubber hose steel wire pay-off spindle that can be pre-shaped, including a spindle L frame, three guide wheels and a shaping shaft 4 are arranged on the spindle L frame, in this embodiment, the three guide wheels They are respectively named the first guide wheel 1, the second guide wheel 2 and the third guide wheel 3. The first guide wheel 1 is installed on the first fixed position of the spindle L frame, and the thickness of the first guide wheel 1 is greater than that of the second guide wheel 2. And the 3rd guide wheel 3, the 2nd guide wheel 2 and the 3rd guide wheel 3 are coaxially arranged, the 2nd guide wheel 2 and the 3rd guide wheel 3 are installed in the second fixed position of the spindle L frame, the 2nd guide wheel 2 and the 3rd guide wheel 3 The third guide wheel 3 has the same outer diameter, the second guide wheel 2 and the third guide wheel 3 are flush, and in the vertical direction, the first guide wheel 1 is higher than the second guide wheel 2 and the third guide wheel 3; the shaping shaft 4 Located between the first guide wheel 1, the second guide wheel 2 and the third guide wheel 3, the length of the shaping shaft 4 is greater than or equal to the distance between the outer end surface of the second guide wheel 2 or the third guide wheel 3 and the spindle L frame Pitch.
[0029] In this embodiment, through the setting of the first guide wheel 1, the second guide wheel 2 and the third guide wheel 3, the steel wire needs to be deformed in a spiral shape. Therefore, the three guide wheels are arranged as a spatial structure that is convenient for steel wire winding. Wherein, the curved surface of the first guide wheel 1 is provided with grooves for steel wire winding, and the curved surfaces of the second guide wheel 2 and the third guide wheel 3 are also provided with grooves for steel wire winding; the second guide wheel 2 and the third guide wheel The wheels 3 have the same thickness, and the thicknesses of the second guide wheel 2 and the third guide wheel 3 are smaller than the first guide wheel 1 . The distance between the outer end surface of the second guide wheel 2 and the spindle L-frame is less than the distance between the outer end surface of the first guide wheel 1 and the spindle L-frame; the distance between the inner end surface of the first guide wheel 1 and the spindle L-shaped frame It is equal to the distance between the inner end surface of the third guide wheel 3 and the L-shaped frame of the spindle.
[0030] In this embodiment, the first guide wheel 1 is installed at the first fixed position through the first rotation shaft, and the second guide wheel 2 and the third guide wheel 3 are installed at the second fixed position through the second rotation shaft. The first rotating shaft and the second rotating shaft are located on the same vertical line.
[0031] When unwinding, the steel wire first passes through the third guide wheel, reaches the shaping shaft 4, and reaches the first guide wheel 1 after half a circle around the shaping shaft 4. When winding on the shaping shaft 4, it is inclined to the direction of the second guiding wheel 2, and then The first guide wheel 1 goes around once and reaches the second guide wheel 2, and the wire is released from the second guide wheel 2 to the braided tube. Because the second guide wheel 2 and the third guide wheel 3 are not on the same plane, there is a height difference relative to the spindle L frame. This height difference is directly reflected on the shaping shaft 4, and the steel wire passing through the shaping shaft 4 will be deformed, so in The pitch is produced when presetting.
[0032] It can be understood that, in this embodiment, the first guide wheel 1, the second guide wheel 2 and the third guide wheel 3 are all used for winding the steel wire, so the first guide wheel 1, the second guide wheel 2 Both the surface roughness and the third guide wheel 3 need to be ensured to prevent slipping.
[0033] It can be understood that the diameter of the first guide wheel 1 is slightly larger than the diameter of the second guide wheel 2 and the third guide wheel 3 , but not more than twice the diameter of the second guide wheel 2 or the third guide wheel 3 .
[0034] The center of circle of the first guide wheel 1, the center of circle of the second guide wheel 2 and the third guide wheel 3, and the setting shaft 4 are arranged in a triangle, and, because they are all used for winding the steel wire, the steel wire will be respectively on the first guide wheel during operation. A guide wheel 1, a second guide wheel 2 and a sizing shaft 4 apply pressure in a fixed direction, therefore, the first rotating shaft, the second rotating shaft and the sizing shaft 4 all have reinforcing devices in corresponding directions, such as pin shafts, support rods .
[0035]Considering that although the position of the steel wire is relatively fixed during winding, due to the height difference between the second guide wheel 2 and the third guide wheel 3 with respect to the spindle L frame in this embodiment, the first guide wheel 1. The steel wires of the second guide wheel 2 and the third guide wheel 3 are not located on the same plane, so they tend to break away from the guide wheels. Furthermore, in this embodiment, the first guide wheel 1, the second guide wheel 2 and the third guide wheel The end faces of the third guide wheel 3 are all provided with flanging, and the outer diameter of turning over is greater than the diameter of the main body of the guide wheel, so that the area where the side of the guide wheel contacts the steel wire forms an annular groove.
[0036] Through the spindle in this embodiment, after the steel wire is output, it can form a spiral bend, so that not only the diameter of the steel wire is shaped, but also the pitch of the steel wire is generated after the shape is set, and the product can be avoided before the core is removed. The length of the mandrel Suitable for the length of the hose, the mandrel can be removed normally. There is no need to use a cutting machine to cut the ends of the mandrel.
[0037] For example, the product requires a fixed length of 100 meters. When the mandrel is less than 100 meters, it cannot be used. With the traditional method, the mandrel is short when it is only 1/3 of its normal service life. Like this just needs to constantly drop into new mandrel, eliminates the mandrel of short length, has caused the huge waste of mandrel, and adopts the scheme among the present embodiment, then can save this part of expenses.

Example Embodiment

[0040] Example 3
[0041] In a typical implementation of the present invention, this embodiment discloses a pre-shaped rubber hose steel wire braiding method, using the braiding machine disclosed in Embodiment 2, because the second guide wheel 2 and the third guide wheel 3 It is coaxial, and there is a height difference relative to the spindle L frame, so the steel wires will have different rotation directions when they go out and in from different guide wheels, as follows:
[0042] When steel wire enters from second guide wheel 2, walks around sizing shaft 4 and first guide wheel 1, when coming out from the 3rd guide wheel 3, steel wire is left-handed on sizing shaft 4, has thus just determined the pitch of left-handed. like Figure 4 shown.
[0043] When the steel wire enters from the third guide wheel 3, bypasses the shaping shaft 4 and the first guiding wheel 1, and comes out from the second guiding wheel 2, the steel wire is right-handed on the shaping shaft 4, so that the left-handed pitch is determined . like Figure 5 shown.
[0044] Figure 4 and Figure 5 middle, Indicates that the steel wire enters, Indicates that the steel wire comes out.
