DETAILED DESCRIPTION

[0018] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings.

[0019] Embodiment 1 The conductor shaping device comprises a frame 1, and a vertical shaping mechanism 2 and a horizontal shaping mechanism 3 are sequentially arranged along the horizontal conducting direction of the conductor, wherein the structures of the vertical shaping mechanism 2 and the horizontal shaping mechanism 3 are the same, and the conductor is sequentially pressed when passing through the two.

[0020] A vertical support wheel 04 is provided at the front side of the vertical shaping mechanism 2 to limit the horizontal position of the twisted conductor, and a horizontal support wheel 4 is provided at the rear side of the horizontal shaping mechanism 3 to assist in the smooth extraction of the twisted conductor after compression.

[0021] The actual index of the stranded conductor (such as the actual pitch of the stranded conductor in this layer) is automatically adjusted in length, that is, different stranded conductor pitches require different horizontal spacing adjustments of the shaping wheel for pressing.

[0022] 1) The pitch is the axial length of a single wire along the surface of the inner layer of the stranded conductor when it rotates a complete spiral around the central axis; 2) Identification of the pitch: taking a single wire as the origin, count the number of single wires specified by the process of the layer of stranded conductor, and the length between them is one pitch.

[0023] Among them, the adjustment method of the five-wheel system (this plan is developed based on the five-wheel system as an example) is: setting the spacing between the wheels on the same side - the middle shaping wheel on the odd-numbered side does not move, and the shaping wheel is used as the axis of symmetry, and the shaping wheels on both sides are adjusted horizontally and equidistantly at the same time - at the same time, the shaping wheels on the even-numbered side are also centered on the middle wheel on the odd-numbered side and adjusted horizontally and equidistantly at the same time; the adjustment method of the seven-wheel system is: setting the spacing between the shaping wheels on the same side - the middle shaping wheel on the odd-numbered side does not move, and the wheel is used as the axis of symmetry, and the shaping wheels on both sides are adjusted horizontally and equidistantly at the same time - the two wheels of the shaping wheels on the even-numbered side use the middle shaping wheel on the odd-numbered side as the axis of symmetry, and the two shaping wheels on each side are adjusted equidistantly at the same time.

[0024] The present application designs and improves the original vertical shaping mechanism 2 and the horizontal shaping mechanism 3 with fixed shaping wheels, so that they have the function of horizontal movement and adjustment.

[0025] See attached Figure 2 As shown, this embodiment is explained by taking the vertical shaping mechanism 2 as an example. The vertical shaping mechanism 2 includes a bracket 21, on which cross bars are arranged at intervals, and on which upper shaping wheels 5 and lower shaping wheels 6 are provided. The upper shaping wheel 5 is slidably connected to an upper slide groove 8 provided on the cross bar through a slider 26, and the lower shaping wheels 6 on both sides are slidably connected to a lower slide groove 7 provided on the cross bar through a slider 26.

[0026] Considering that the horizontal spacing of the upper shaping wheel must correspond to the pitch, its movement process needs to be accurate. That is, no matter how it moves, the upper shaping wheel 5 must always be located in the middle of the two lower shaping wheels 6 below. Therefore, this embodiment provides an auxiliary positioning structure so that when the upper shaping wheel 5 moves a displacement distance, the lower shaping wheel 6 moves 2 displacement distances accordingly. Figure 3 As shown, a movable pulley 9 is arranged outside the upper shaping wheel 5, and a pull rope 11 is connected between the center of the movable pulley 9 and the slider 26 of the upper shaping wheel 5, and a pull rope 2 10 is wound around the upper half of the movable pulley 9, and the two free ends of the pull rope 2 10 extend outward respectively, wherein the upper free end of the pull rope 2 10 is connected to the vertical pillar 12, and the lower free end of the pull rope 2 10 passes through the through slot 14 provided on the pillar 12 and is connected to the inclined pillar 13, and secondly, a support 20 is arranged on the rear side of the horizontal bar of the movable pulley 9, and the movable pulley 9 is horizontally slidably connected to the support 20 through a moving block. When in use, the lower shaping wheel 6 is synchronously driven to move when the pillar 12 is pulled, and the upper shaping wheel 5 is synchronously driven to make half a displacement distance through the movable pulley 9, that is, the corresponding wire pitch adjustment can be achieved by only controlling the displacement distance of the lower shaping wheel 6.

[0027] Graduations can be drawn on the horizontal bar at the rear side of the support 12 to quickly and intuitively adjust the displacement of the lower shaping wheel 6.

[0028] Embodiment 2 Considering the different outer diameters of the stranded conductors, the wire shaping device needs to match wires of different outer diameters. Therefore, the vertical spacing between the upper and lower shaping wheels 6 needs to be adjusted. Therefore, this embodiment improves the adjustment of the vertical height on the basis of the first embodiment.

[0029] See attached Figure 4-6 As shown, the horizontal piece connected to the upper shaping wheel 5 adopts a lifting seat 22, and is lifted and lowered by a screw rod 23. The auxiliary positioning structure includes a movable pulley 9 arranged outside the upper shaping wheel 5, a pull rope 11 is connected between the center of the movable pulley 9 and a slider 26 of the upper shaping wheel 5, a pull rope 2 10 is wound around the upper half of the movable pulley 9, and the two free ends of the pull rope 2 10 extend outward respectively, wherein the upper free end of the pull rope 2 10 is connected to the vertical pillar 12, and the lower free end of the pull rope 2 10 passes through the through slot 14 opened on the pillar 12 and is connected to the straight pillar 16, wherein the pillar 12 and the straight pillar 16 are on the same horizontal plane. The pillar 12 and the straight column 16 are provided with a long groove 14 and a long groove 25, respectively. A sliding block is slidably connected to the long groove 14, and a moving block is slidably connected to the long groove 25. The sliding block is connected to the upper free end of the pull rope 2 10. The lifting seat 22 is connected to the sliding block through the support 20. Secondly, the sliding block is connected to the moving block through the inclined rod 17. When the lifting seat 22 moves in the vertical direction, it can synchronously drive the moving block, the sliding block and the slider 26 connected to the other end of the truing wheel through the pull rope 11 to move up and down (the slider 26, the moving block and the sliding block together form a stable support in three directions of the movable pulley 9).

[0030] Secondly, the above design should also not affect / block the horizontal movement of the movable pulley 9. Figure 5As shown, the lower side of the support 20 is horizontally slidably connected to the sliding block, and a through long slot 19 with a lateral dimension larger than the support 20 is provided on the upper side of the pillar 12 so as not to affect the lateral movement of the movable pulley 9. Of course, the support 20 can also be directly connected to the lifting seat 22 in a horizontally slidable manner.

[0031] Embodiment 3 The degree to which the shaping wheel presses tightly against the twisted conductor is prone to inconsistent pressure. The problem that occurs during actual use is that the degree of pressure is inconsistent, resulting in some shaping wheels pressing down while others do not (mostly occurring on the lower shaping wheel). Therefore, it is necessary to upgrade this unified opening and closing system to make the degree of contact between the shaping wheel and the twisted conductor consistent.

[0032] That is, the degree to which the shaping wheel presses the wire (downward pressure) can be automatically adjusted according to wires of different hardness materials (such as aluminum wire and aluminum alloy wire), and the downward pressure degree can also be adjusted by the size of the tangential force that causes the shaping wheel to rotate after the shaping wheel contacts the twisted conductor.

[0033] That is, under the premise that the pressure is consistent, the spring 30 can be used to automatically adjust the downward pressure. Under the premise of forming an organic whole with the device in the second embodiment, this embodiment is improved as follows. Figure 7 As shown, a half-wrapped enclosure is provided at the lower shaping wheel, and the inner end of the enclosure 28 is slidably connected to the slider 26 in the vertical direction through the base block 27. The two ends of the lower shaping wheel 6 are respectively pivoted to the base block 27 and the inner wall of the enclosure 28. The bottom of the enclosure 28 is connected to a slide seat 29 through a spring 30. The slide seat 29 is horizontally slidably connected to the bracket 21, so that the downward pressure of the shaping wheel can be adjusted without affecting its horizontal movement.

[0034] It should be noted that the process setting of the outer diameter of any layer of twisted conductor or the actual outer diameter of the twisted conductor measured by a diameter gauge can automatically calculate the matching shaping wheel diameter range; according to the covering rate process requirements of the outer surface of the twisted conductor covered by the wire slot, the shaping wheel R arc radius range is automatically calculated, and reference suggestions are given for users to select the shaping wheel size.

[0035] The specific embodiments described above further illustrate the objectives, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
