Description

Technical Field

[0001] The utility model relates to the technical field of cable processing, in particular to a wire cutting machine and a cable shielding net cutting and turning mechanism thereof. Background Art

[0002] High-voltage cables mainly provide high voltage and strong electricity. Compared with low-voltage cables that do not require shielding protection, due to the high voltage in high-voltage cables, a layer of shielding net is required to form electromagnetic shielding protection. Otherwise, the adjacent electrical devices or equipment will be affected by electromagnetic radiation and then fail. Therefore, it is necessary to avoid the influence of electromagnetic radiation. In high-voltage cables, in addition to the high-voltage cable core that mainly plays a conductive role, the outer surface of the core is also covered with an inner insulation layer, a shielding net and an outer insulation layer in sequence. In order to effectively connect the shielding net with other equipment, the shielding net needs to be connected to the shielding ring, and then connected to other equipment through the shielding ring to ensure that the connection between the shielding net and other equipment meets the relevant electrical requirements.

[0003] For the shielding net cutting and flipping mechanism of the high-voltage cable, after completing the shielding net cutting step, since the relative positions of the components inside the shielding net cutting and flipping mechanism need to be adjusted to perform the shielding net flipping step, the cable exits the positioning component under the drive of the holding component and waits to enter the positioning component next time. The end of the cable away from the holding component will sag under the action of gravity because it is not fixed, causing the cable to become eccentric after entering the positioning component next time, affecting the shielding net flipping step. This situation is more obvious for cables with small wire diameters. Utility Model Content

[0033] Please continue reading Figure 4 Optionally, in this embodiment, the first wire groove 14411 and the second wire groove 14421 are semicircular grooves with equal radius, and when the first wire claw 1441 and the second wire claw 1442 are in contact, the cross section of the formed support hole 1444 can be adapted to the cross section of the cable. Of course, those skilled in the art can also set the shapes of the first wire groove 14411 and the second wire groove 14421 according to actual conditions, as long as the function of keeping the cable horizontal can be achieved.

Specifically, when the first wire claw 1441 abuts the second wire claw 1442, since the first protrusion 14412 matches the second groove 14423 and the second protrusion 14422 matches the first groove 14413, the contact area between the first wire claw 1441 and the second wire claw 1442 is larger, thereby improving the reliability during abutment.

[0035] It should be noted that, in the present embodiment, the first wire claw 1441 and the second wire claw 1442 can be replaced according to the radius of the cable to accommodate cables with different wire diameters during the cable processing.

[0036] Please continue reading Figure 3 Optionally, in this embodiment, the positioning assembly 140 also includes a guide shaft 141, a wire-paying slider 142 and a wire slider 143. One end of the guide shaft 141 is fixedly connected to the first vertical plate 111, and the other end is fixedly connected to the second vertical plate 112. The number of guide shafts 141 is multiple. The wire slider 143 is sleeved on the guide shaft 141 and can reciprocate between the first vertical plate 111 and the second vertical plate 112 along the axial direction of the guide shaft 141. The wire slider 143 is used to guide the cable to extend into the positioning assembly 140. The wire-paying slider 142 is provided on the first vertical plate 111 and slides back and forth along the width direction of the workbench 110. When the cable shielding net cutting and flipping mechanism 100 performs the step of cutting the shielding net, the wire slider 143 and the wire-paying slider 142 are used to fix the cable.

[0037] As for other structural features of the driving assembly 120 , the holding assembly 130 , the cutting assembly 150 and the flipping assembly 160 , they are within the scope of understanding of those skilled in the art and will not be elaborated here.

[0038] The above is a description of the various structural components, connection relationships and functions of this embodiment. The specific working process of the cable shielding net cutting and flipping mechanism 100 will be described below in combination with this embodiment.

[0039] In the present embodiment, when the cable shielding net cutting and flipping mechanism 100 is required to perform the cable shielding net cutting and flipping steps, firstly, one end of the cable is fixed by the holding assembly 130, and then the holding assembly 130 is started to slide toward the direction of the first vertical plate 111, and the other end of the cable passes through the support hole 1444, and with the assistance of the wire clamping support device 144, it passes through the wire release slider 142 and the wire slider 143 in a horizontal state, and extends into the positioning assembly 140. The wire slider 143 repeatedly squeezes and rolls the shielding net, so that the shielding net of the cable is slightly unfolded, and then the driving assembly 120 drives the cutting assembly 150 to extend into the positioning assembly 140 and rotate to cut the shielding net of the cable, and the step of cutting the shielding net is completed. Subsequently, the step of flipping the shielding net needs to be performed. Since the wire-paying slider 142 will affect the flipping of the cable shielding net, it is necessary to first use the holding component 130 to cooperate with the wire clamping support device 144 to make the cable horizontally exit the wire-paying slider 142, and then the wire-paying slider 142 slides on the first vertical plate 111 along the side of the first vertical plate 111 in the width direction of the workbench 110, and then the holding component 130 cooperates with the wire clamping support device 144 to make the cable horizontally enter the wire slider 143, and then the wire slider 143 is used to fully open the shielding net. Under the drive of the driving component 120, the flipping component 160 moves toward the direction of the wire slider 143 and passes through the wire slider 143, and then the opened shielding net is turned outward, and the step of flipping the shielding net is completed. Finally, the flipping component 160 is driven by the driving component 120 to move away from the positioning component 140, and the cable is also moved away from the positioning component 140 through the holding component 130 and the wire clamping support device 144, and the cable shielding net cutting and flipping steps are completed.

[0040] Furthermore, the present invention also provides a wire cutting machine 200, see Figure 6-Figure 7 , Figure 6 This is a three-dimensional structural diagram of an embodiment of the utility model wire cutting machine.

The wire cutting machine 200 includes but is not limited to the aforementioned cable shielding net cutting and flipping mechanism 100 , the electrical control unit 210 and the cover 220 .

[0041] Specifically, the cable shielding net cutting and flipping mechanism 100 is arranged above the electrical control unit 210, and a storage space for placing the electrical control unit 210 is provided below the wire cutting machine 200. The cable shielding net cutting and flipping mechanism 100 and the electrical control unit 210 are both covered by a machine cover 220, which can protect the cable shielding net cutting and flipping mechanism 100 and the electrical control unit 210 and extend the service life of the wire cutting machine 200.
