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 flipping 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] There are two main existing technologies for processing shielding nets of high-voltage cables: one is to press the shielding net with a blade to disperse and open a part of it, and then use an inner guide tube to partially insert it and then push it forward in combination with the outer guide tube to flip the shielding net. This method of flipping the shielding net requires two mechanisms to complete the cutting and flipping actions, which is inefficient and has a complicated process. The second is to use a high-speed rotating brush to break up the shielding net, and then use the brush to flip the shielding net, but the brush will cause a certain amount of damage to the cable, and at the same time, a large amount of dust will remain in the gap between the workshop and the equipment, which is harmful to the human body.

[0034] As for the existing cable shielding net processing mechanisms, one method is to press the shielding net with a blade to disperse and open a part of it, and then use an inner guide tube to partially extend it and then push it forward in combination with the outer guide tube to flip the shielding net. However, this method of flipping the shielding net requires two mechanisms to complete the actions of cutting and flipping the shielding net, which is inefficient and has a complicated process. The other method is to use a high-speed rotating brush to break up the shielding net, and then use the brush to flip the shielding net. Since the brush will cause different degrees of damage to the cable, and at the same time, a large amount of dust will remain in the gap between the workshop and the equipment, which will cause certain harm to the human body and will cause equipment failure in the long run. The above two methods are not competitive in the market.

When the cable shielding net needs to be cut and the flipping mechanism 100 processes the shielding net, one end of the cable is fixed by the wire clamp 134. Under the drive of the first cylinder 131, the slider is driven to move along the guide rail 133 in the length direction of the workbench 110, so that the cable passes through the first vertical plate 111 and extends into the positioning assembly 140, so as to facilitate the subsequent shielding net cutting and flipping process steps. The protective cover 135 can prevent the splashing of dust and debris, and play a protective role for the operator and the workshop. After the shielding net cutting and flipping process steps are completed, the first cylinder 131 can drive the slider to move along the guide rail 133 in the length direction of the workbench 110, and the cable exits the positioning assembly 140.

It should be noted that the terms "first", "second" and the like in the embodiments of the present application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined by terms such as "first", "second", etc. may explicitly or implicitly include at least one such feature. In the description of the present utility model, "plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

Specifically, the first slider 142 is sleeved on at least one first guide shaft 141 and reciprocates between the first vertical plate 111 and the second vertical plate 112 along the axial direction of the first guide shaft 141. A spiral guide groove 1421 is provided in the middle of the first slider 142. When the cable passes through the first vertical plate 111 and extends into the positioning assembly 140, the spiral guide groove 1421 is used to guide The cable guide extends into the positioning assembly 140 and fixes one end of the cable, and at the same time plays the role of keeping the cable in a horizontal state. The side wall of the spiral guide groove 1421 is provided with a retractable hexagonal pressing knife 1422, which is used to open the shielding net of the cable. Before the process step of cutting the shielding net, the hexagonal pressing knife 1422 extends from the side wall of the spiral guide groove 1421, and repeatedly squeezes and rolls the shielding net to open the edge of the shielding net for the subsequent shielding net cutting step. It can be seen that the hexagonal pressing knife 1422 includes several blades.

[0053] 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.

[0054] 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 wire clamp 134 of the holding assembly 130, and then the first cylinder 131 is started, and the wire clamp 134 is driven to slide on the guide rail 133 toward the first vertical plate 111 through the first synchronous wheel 132, and the other end of the cable is extended into the spiral guide groove 1421 of the first slider 142 through the limiting hole 1431 of the second slider 143, and then the hexagonal pressing knife 1422 is extended from the side wall of the spiral guide groove 1421, and the shielding net of the cable is slightly expanded by repeatedly squeezing and rolling the shielding net so that the cutting shielding conduit 153 can be extended into the shielding net. The inner wall of the shielding cutter 153 is extended into the inner wall of the shielding net, and the spiral guide groove 1421 slides on the first guide shaft 141 toward the first vertical plate 111 and is close to the second slider 143. Then the shielding cutter 153 slides toward the first vertical plate 111 and is close to the annular block 1442. The annular block 1442 serves as a working platform of the cutting component 150 at this time, providing a force point for the cutting component 150. Driven by the second cylinder 154, it rotates forward and reverse at high speed to cut the shielding net and then stay away from the cable. The first slider 142 is reset, and at the same time, the cleaning device 145 jets and cleans the spiral guide groove 1421 and the shielding cutter 153 through the air guide pipe 1451, and the step of cutting the shielding net is completed. Then, the step of flipping the shielding net is performed. Since the second slider 143 will affect the flipping of the cable shielding net, it is necessary to first use the holding component 130 to make the cable exit the second slider 143. The second slider 143 slides on the sliding channel 1111 along the side of the first vertical plate 111 in the width direction of the workbench 110. The cable then passes through the holding component 130 to make the cable enter the spiral guide groove 1421. Then, the shielding net is fully opened by cutting the shielding conduit 153 and cooperating with the hexagonal pressing knife 1422, and then the shielding conduit 153 is flipped over. Driven by the third cylinder 162, the shielding duct 161 moves toward the spiral guide groove 1421 and passes through the spiral guide groove 1421, so that the opened shielding net is turned outward, and the step of flipping the shielding net is completed. The shielding duct 161 exits the positioning assembly 140 under the drive of the driving assembly 120, and finally the first cylinder 131 is started, and the wire clamp 134 is driven by the first synchronous wheel 132 to slide on the guide rail 133 away from the first vertical plate 111, and the cable shielding net cutting and flipping steps are completed.

[0055] Furthermore, the present invention also provides a wire cutting machine 200, see Figure 10-11 , Fig.10 This is a three-dimensional structural diagram of an embodiment of the utility model wire cutting machine. Fig.11 yes Fig.10 The wire cutting machine shown is a three-dimensional structural schematic diagram without part of its cover. 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.

[0056] 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.

[0057] Please continue reading Fig.11 Optionally, in this embodiment, the wire cutter 200 also includes a collection container 230, which is arranged in the storage space and directly below the positioning component 140. The collection container 230 is used to collect shielding net debris, dust and other materials dropped by the cleaning device 145 through the air duct 1451 when the cleaning device 145 jets clean, so as to prevent the shielding net debris, dust and other residues on the surface of the spiral guide groove 1421 and the cutting component 150 from affecting the processing of the cable, and at the same time ensure the normal operation of the electrical control unit 210.

[0058] The beneficial effects of the utility model are as follows: the cable shielding net cutting and flipping mechanism is configured as a driving component, a workbench, and a holding component, a positioning component, a flipping component and a cutting component which are sequentially arranged along the length direction of the workbench, wherein the holding component and the positioning component jointly hold and keep the cable in a horizontal state, the cutting component is used to cut the shielding net, the flipping component is used to flip the shielding net, and the driving component is used to drive the cutting component and the flipping component to perform reciprocating motion along the length direction of the workbench, so that the process steps of cutting and flipping the shielding net are completed in one mechanism, thereby improving the process efficiency of cutting and flipping the cable shielding net, reducing the difficulty of operation, simplifying the process flow, and reducing the errors between multi-step operations.
