Description

Technical Field

[0001] The invention relates to the technical field of cable processing, in particular to a flame retardant power cable processing device and method. Background Art

[0002] Cables are made of one or more mutually insulated conductors and an outer insulating protective layer, and are used to transmit electricity or information from one place to another. They are usually rope-like cables made of several or several groups of conductors twisted together. Each group of conductors is insulated from each other and often twisted around a center. The entire outer layer is covered with a highly insulating covering layer. Flame-retardant cables are cables that may be burned and unable to operate in the event of a fire, but can prevent the spread of fire. However, in the process of processing flame-retardant cables, they need to be processed according to specific application scenarios. Usually, flame-retardant cables need to be cut into segments of different lengths according to different requirements. However, since the cables are coiled together after production, the cut segments of the flame-retardant cables are not necessarily straightened during the cutting process due to the bending state of the flame-retardant cables. As a result, the length of the flame-retardant cables after cutting is uneven, which affects the use of subsequent flame-retardant cable application scenarios. Moreover, if the flame-retardant cables are cut in a skewed state, the cut ends of the flame-retardant cables will be skewed, thereby affecting the conductivity and insulation of the flame-retardant cables. Therefore, we propose a flame-retardant power cable processing device and method. Summary of the invention

[0003] In view of the problem in the above or prior art that the cables are coiled together after production, during the cutting process, due to the bent state of the flame retardant cable, the cut sections of the flame retardant cable are not necessarily in a straightened state, resulting in uneven lengths of the flame retardant cables after cutting, thereby affecting the use of subsequent flame retardant cable application scenarios, and if the flame retardant cable is cut in a skewed state, the incision of the flame retardant cable will be skewed, thereby affecting the conductivity and insulation of the flame retardant cable, the present invention is proposed.

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1, reference Figures 1 to 5, which is the first embodiment of the present invention, provides a flame-retardant power cable processing device, which can realize the straightening operation of the cut part of the flame-retardant cable, and at the same time can complete the compression and positioning effect of the two ends of the cut part of the flame-retardant cable, including a straightening mechanism 100, which includes a processing table 101, an auxiliary frame 112 arranged on the processing table 101 for straightening the flame-retardant cable, and also includes a compression rod 104 symmetrically arranged on the auxiliary frame 112, and a lower pressing plate 108 arranged above the processing table 101, a retaining plate 109 is connected to one side of the lower pressing plate 108, and a wedge plate 113 is arranged below the auxiliary frame 112, The driving assembly includes a driving box 103 arranged above the processing table 101, a servo motor 126 is arranged at the upper end of the inner cavity of the driving box 103, a transmission rod 128 is installed at the output end of the servo motor 126, a rack 127 is arranged at the lower end of the lower pressure plate 108, a gear 129 is arranged at the upper end of the transmission rod 128, and a centering positioning mechanism 200 includes a support frame 201, a straight rod 202 slidably arranged on the support frame 201 for centering the flame-retardant cable, and an inclined rod 204 welded at the end of the straight rod 202, and the inclined rod 204 is symmetrically arranged, and a traction rope 206 is fixedly connected to the inner side of the upper end of the straight rod 202.

[0034] The clamping rod 104 is movably connected to one side of the driving box 103, one end of the lower pressure plate 108 is fixedly connected to the retaining plate 109 by welding, the front and rear sides of the driving box 103 are fixedly connected to the upper end of the processing table 101 through support bars, and the servo motor 126 is detachably installed on the upper end of the inner cavity of the driving box 103 by bolts. The lower end of the lower pressure plate 108 is fixedly connected to the rack 127, and the upper end of the straight rod 202 is slidably connected to the support frame 201.

[0035] In this embodiment, the transmission rod 128 is driven to rotate by the servo motor 126, and the gear 129 at the upper end of the transmission rod 128 drives the rack 127 to rotate accordingly, and the rack 127 drives the lower pressure plate 108 and the fixed plate 107 to move to the right at the same time, thereby driving the clamping rod 104 and the wedge plate 113 to move downward, so that the first rubber plate 106 on the clamping rod 104 is clamped and limited to the left side of the cutting part of the flame-retardant cable. While controlling the fixed plate 107 and the lower pressure plate 108 to continue to move to the right, the flame-retardant cable at the clamping part at the right end is moved to the right for straightening and clamping operations, thereby ensuring that the length of the flame-retardant cable after cutting is consistent, and through the cooperation of the centering positioning mechanism 200, the flame-retardant cable can be centered before the right end of the flame-retardant cable is clamped, thereby avoiding the situation where the incision of the flame-retardant cable is skewed, affecting the conductivity and insulation of the flame-retardant cable.

[0036] The straightening mechanism 100 also includes a first clamping assembly, which includes a cutting frame 102 arranged above the processing table 101, a clamping rod 104 is arranged on one side of the driving box 103, a ball head 110 is arranged on the upper end of the clamping rod 104, a first rubber plate 106 is arranged on the end of the clamping rod 104 away from the ball head 110, a first spring 105 is sleeved on the outer wall of the lower end of the clamping rod 104, and a slope is arranged at one end of the lower pressure plate 108, and the slope end of the lower pressure plate 108 is aligned with one end of the retaining plate 109.

[0037] In this embodiment, the cutting frame 102 is fixedly installed above the processing table 101 by bolts, the clamping rod 104 is movably connected to one side of the driving box 103, and the upper end of the clamping rod 104 is fixedly connected to the ball head 110 by welding, and the other end of the clamping rod 104 is detachably connected to the first rubber plate 106. When the lower pressing plate 108 moves to the right, the left inclined surface of the lower pressing plate 108 will contact the upper ball head 110 of the clamping rod 104, and the inclined surface will push the ball head 110 to move downward, thereby driving the clamping rod 104 to move downward, and at the same time, the first spring 105 is in a stretched state. When the clamping rod 104 loses the downward pressure, the first spring 105 will drive the clamping rod 104 to reset, thereby causing the first rubber plate 106 on the clamping rod 104 to contact the resistance The flame retardant cable is separated. When the upper end of the ball head 110 is transferred from the inclined surface of the lower pressure plate 108 to the bottom of the retaining plate 109, the clamping rod 104 moves into place and no longer moves downward, so that the first rubber plate 106 under the clamping rod 104 clamps and limits the left side of the cutting part of the flame retardant cable. Moreover, since the left side of the cutting part of the flame retardant cable is in a continuously clamped state, the displacement of the flame retardant cable during the straightening process of the right side of the flame retardant cable is avoided, and the clamped flame retardant cable is convenient for cutting operation. Moreover, after the ball head 110 is transferred from the inclined surface of the lower pressure plate 108 to the retaining plate 109, the retaining plate 109 will apply a continuous downward pressure to the ball head 110, thereby ensuring that the clamping rod 104 is not affected during the continuous movement of the lower pressure plate 108 to the right.

[0038] Specifically, the lower pressure plate 108 is arranged above the ball head 110, and a fixing plate 107 is welded on the other side of the lower pressure plate 108. A positioning rod 107a is arranged on the other side of the driving box 103. One end of the positioning rod 107a passes through the middle of the fixing plate 107, and the fixing plate 107 is movably connected to the positioning rod 107a. A fixing bar 111 is arranged in the middle of the lower end of the fixing plate 107.

[0039] In this embodiment, the positioning rod 107a is fixedly installed on the other side of the drive box 103 by welding, and the lower end of the fixed plate 107 is fixedly connected to the fixing bar 111 by welding. The positioning rod 107a is movably connected to the fixing plate 107. During the left and right movement of the fixing plate 107, the position of the fixing plate 107 is limited by the positioning rod 107a, and due to the square setting of the positioning rod 107a, the stability of the movement of the fixing plate 107 is guaranteed. During the movement of the fixing plate 107, the fixing bar 111 will be driven to follow the movement, thereby completing the pushing operation of the auxiliary frame 112 in linkage.

[0040] Furthermore, the straightening mechanism 100 also includes a second clamping assembly, which includes a wedge plate 113 arranged below the auxiliary frame 112, a push plate 114 is arranged at the upper end of the wedge plate 113, a second rubber plate 115 is arranged at the lower end of the wedge plate 113, and the length of the second rubber plate 115 is greater than the length of the wedge plate 113. Slide grooves 117 are provided on the front and rear sides of the cutting frame 102, a slide plate 119 is provided on the inner side of the lower end of the auxiliary frame 112, and the slide plate 119 is slidably connected to the slide groove 117. A second spring 118 is provided at one end of the inner cavity of the slide groove 117, and the other end of the second spring 118 is fixedly connected to the slide plate 119. A slot 116 is provided in the middle of one side of the auxiliary frame 112.

[0041] In this embodiment, the upper end of the wedge plate 113 is fixedly installed with a push plate 114 by welding, and the lower end of the wedge plate 113 is bonded with a second rubber plate 115 by gluing, and the slide plate 119 is fixed to the inner side of the lower end of the auxiliary frame 112 by welding. During the movement of the fixed plate 107, the fixed strip 111 on the fixed plate 107 will first be inserted into the slot 116 of the auxiliary frame 112, and the fixed strip 111 inserted into the slot 116 pushes the auxiliary frame 112 to move rightward. During the movement of the auxiliary frame 112 to the right, the lower end of the auxiliary frame 112 will push the wedge plate 113 along the inclined surface of the wedge plate 113, thereby driving the wedge plate 113 to move downward until the second rubber plate 115 under the wedge plate 113 is pressed on the flame-retardant cable cutting On the right side of the part, when the first rubber plate 106 on the clamping rod 104 compresses and limits the flame-retardant cable, the second rubber plate 115 on the wedge plate 113 will contact the upper surface of the flame-retardant cable. At this time, the flame-retardant cable on the right side will not be compressed and limited. At the same time, when the auxiliary frame 112 moves to the right, the slide plate 119 at the lower end of the auxiliary frame 112 will slide along the direction of the slide groove 117, thereby ensuring the stability of the movement of the auxiliary frame 112. At the same time, when the auxiliary frame 112 moves to the right, the second spring 118 is in a stretched state. After the auxiliary frame 112 loses its driving force, the second spring 118 will drive the auxiliary frame 112 to reset, thereby quickly separating the auxiliary frame 112 from the wedge plate 113, thereby facilitating the removal of the flame-retardant cable that has been cut.

[0042] Among them, the straightening mechanism 100 also includes a reset component, which includes a connecting rod 120 arranged on the other side of the wedge plate 113, and a sliding rod frame 122 is movably installed at both the front and rear ends of the connecting rod 120, and the lower end of the sliding rod frame 122 is slidably connected to the sliding groove 117, and the outer wall of the sliding rod frame 122 is provided with a third spring 121, and the upper end of the third spring 121 is fixedly connected to the lower end of the connecting rod 120, and a fourth spring 123 is provided at the other end of the inner cavity of the sliding groove 117, and the other end of the fourth spring 123 is fixedly connected to the lower end of the sliding rod frame 122.

[0043] In this embodiment, the connecting rod 120 is fixedly connected to the wedge plate 113 by welding, and the other end of the inner cavity of the slide groove 117 is fixedly installed with a fourth spring 123. When the wedge plate 113 moves downward, the wedge plate 113 will drive the connecting rod 120 to move along, and the two ends of the connecting rod 120 will compress the third spring 121. When the auxiliary frame 112 is separated from the wedge plate 113, the third spring 121 is spliced ​​with the spring rebound elasticity, and the third spring 121 will drive the connecting rod 120 to reset, and then drive the wedge plate 113 on the connecting rod 120 to reset, so that the second rubber plate 115 on the wedge plate 113 is separated from the flame-retardant cable, which is convenient for removing the cut flame-retardant cable. After the first rubber plate 106 presses the left flame-retardant cable and the second rubber plate 115 contacts the right flame-retardant cable, Continue to control the transmission rod 128 to rotate, the gear 129 on the transmission rod 128 will drive the rack 127 to continue to move to the right, so that the first rubber plate 106 continues to press the left flame-retardant cable. At the same time, due to the friction between the upper end of the cable and the second rubber plate 115, when the auxiliary frame 112 moves to the right, the second rubber plate 115 on the wedge plate 113 will exert a rightward pulling trend on the flame-retardant cable on the right, thereby driving the contacted flame-retardant cable on the right side to be straightened and applying pressure downward at the same time. When the cut part of the flame-retardant cable is straightened, the wedge plate 113 cooperates with the second rubber plate 115 to press the flame-retardant cable on the right side, thereby completing the straightening operation of the cut section of the flame-retardant cable, avoiding the situation where the cutting length of the flame-retardant cable is uneven, thereby facilitating the use of subsequent flame-retardant cable application scenarios.

[0044] Preferably, the gear 129 is arranged on the front side of the rack 127, and the gear 129 is meshed with the rack 127. At least two hydraulic cylinders 124 are arranged at the lower end of the inner cavity of the driving box 103, and the hydraulic cylinders 124 are symmetrically arranged. A cutter head frame 125 is arranged at the lower output end of the hydraulic cylinder 124, and the cutter head frame 125 is arranged directly above the cutting groove of the cutting frame 102.

[0045] In this embodiment, through the cooperation of the gear 129 and the rack 127, the lower pressure plate 108 and the fixed plate 107 can be driven to move left and right during the rotation of the transmission rod 128. When the flame-retardant cable is straightened and pressed into place, the hydraulic cylinder 124 is controlled to open, and the hydraulic cylinder 124 drives the cutter head frame 125 to cut the cutting part of the flame-retardant cable.

[0046] When in use, first turn on the servo motor 126 to drive the transmission rod 128 to rotate forward, and the gear 129 at the upper end of the transmission rod 128 drives the rack 127 to rotate accordingly, and the rack 127 drives the lower pressure plate 108 and the fixed plate 107 to move to the right at the same time. During the movement of the lower pressure plate 108 to the right, the left inclined surface of the lower pressure plate 108 will contact the upper ball head 110 of the clamping rod 104, and the inclined surface will push the ball head 110 to move downward, thereby driving the clamping rod 104 to move downward, and at the same time the first spring 105 is in a stretched state. When the clamping rod 104 loses the downward pressure, the first spring 105 will drive the clamping rod 104 to reset, thereby making the first spring 105 on the clamping rod 104 A rubber plate 106 is separated from the flame-retardant cable. When the upper end of the ball head 110 is transferred from the inclined surface of the lower pressure plate 108 to the bottom of the retaining plate 109, the clamping rod 104 moves to its position and no longer moves downward, so that the first rubber plate 106 below the clamping rod 104 clamps and limits the left side of the cut portion of the flame-retardant cable. When the lower pressure plate 108 moves to the right, the fixing plate 107 moves along with it. The fixing strip 111 on the fixing plate 107 is first inserted into the slot 116 of the auxiliary frame 112. The fixing strip 111 is inserted into the slot 116 to push the auxiliary frame 112 to move to the right. When the auxiliary frame 112 moves to the right, the lower end of the auxiliary frame 112 moves along the wedge plate The inclined surface of 113 pushes the wedge plate 113, thereby driving the wedge plate 113 to move downward until the second rubber plate 115 below the wedge plate 113 presses on the right side of the flame retardant cable cutting position. When the first rubber plate 106 on the clamping rod 104 clamps and limits the flame retardant cable, the second rubber plate 115 on the wedge plate 113 will contact the upper surface of the flame retardant cable, and will not clamp and limit the flame retardant cable on the right side. Then continue to control the transmission rod 128 to rotate, and the gear 129 on the transmission rod 128 will drive the rack 127 to continue to move rightward, so that the first rubber plate 106 continues to clamp the flame retardant cable on the left side. The friction force between the upper end of the cable and the second rubber plate 115 is such that when the auxiliary frame 112 moves to the right, the second rubber plate 115 on the wedge plate 113 will exert a tendency to pull the flame-retardant cable on the right side to the right, thereby driving the flame-retardant cable on the right side in contact to be straightened and applying downward pressure at the same time. When the cut portion of the flame-retardant cable is straightened, the wedge plate 113 cooperates with the second rubber plate 115 to press the flame-retardant cable on the right side, thereby completing the straightening operation of the cut section of the flame-retardant cable. When the flame-retardant cable is straightened and pressed into place, the hydraulic cylinder 124 is controlled to open, and the hydraulic cylinder 124 drives the cutter head frame 125 to move downward to cut the cut portion of the flame-retardant cable.

[0047] Example 2, reference Figures 1 to 8, which is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a flame-retardant power cable processing device, which solves the problem that the flame-retardant cable is cut in a skewed state, which will cause the incision of the flame-retardant cable to be skewed, thereby affecting the conductivity and insulation of the flame-retardant cable. It includes a centering positioning mechanism 200 and a traction component. The traction component includes a fixed block 205 arranged in the inner cavity of the slot 116, and both sides of the fixed block 205 are connected to a traction rope 206, and the other end of the traction rope 206 is connected to the inner side of the upper end of the straight rod 202. The outer side of the support frame 201 is provided with a fifth spring 203, and the other end of the fifth spring 203 is fixedly connected to the outer side of the upper end of the straight rod 202.

[0048] In this embodiment, when the fixing strip 111 is inserted into the slot 116, the fixing strip 111 will first contact the fixing block 205 in the slot 116, thereby pushing the fixing block 205 to move rightward along the slot 116. When the fixing block 205 moves rightward, the fixing block 205 will pull the traction rope 206, and the traction rope 206 drives the straight rod 202 on the support frame 201 to slide toward the middle, so that the oblique rod 204 on the straight rod 202 moves toward the middle, thereby pushing the flame-retardant cable on the cutting frame 102 to the center. When the flame-retardant cable is pushed to the center position, The fixing strip 111 will drive the fixing block 205 to press against the right inner wall of the slot 116, thereby driving the auxiliary frame 112 to move to the right, thereby avoiding the situation where the second rubber plate 115 cannot be centered after contacting the flame-retardant cable, thereby avoiding the situation where the incision is skewed during the cutting process of the flame-retardant cable. When the straight rod 202 moves toward the middle, the fifth spring 203 will be stretched. When the fixing block 205 loses its driving force, the fifth spring 203 will drive the fixing block 205 to reset by virtue of the spring resilience, thereby facilitating the centering operation of the flame-retardant cable next time.

[0049] Specifically, the two oblique rods 204 are in an inverted eight shape, and the upper end of the oblique rod 204 and the lower end of the straight rod 202 also form an inclined angle, the size of the fixing bar 111 is adapted to the size of the slot 116, the fixing bar 111 is movably connected to the slot 116, and the fixing block 205 is slidably connected in the inner cavity of the slot 116.

[0050] Furthermore, it is convenient to cooperate with the oblique rod 204 set in an inverted eight shape, so that the flame-retardant cable can be pushed in the center, thereby improving the accuracy of the cutting process of the flame-retardant cable and reducing the influence of the skewed incision on the conductivity and insulation of the flame-retardant cable. In addition, since the fixed block 205 is slidingly connected in the slot 116, the stability of the movement of the fixed block 205 in the slot 116 is guaranteed, and the traction ropes 206 at both ends of the fixed block 205 can be effectively pulled, thereby driving the oblique rod 204 to move toward the middle, so as to achieve the effect of centering the flame-retardant cable.

[0051] The rest of the structure is the same as that of Example 1.

[0052] When in use, the fixing strip 111 will first contact the fixing block 205 in the slot 116, thereby pushing the fixing block 205 to move to the right along the direction of the slot 116. When the fixing block 205 moves to the right, the fixing block 205 will pull the traction rope 206, and the traction rope 206 drives the straight rod 202 on the support frame 201 to slide toward the middle, so that the oblique rod 204 on the straight rod 202 moves toward the middle, thereby pushing the flame-retardant cable on the cutting frame 102 to the center. When the flame-retardant cable is pushed to the center position, the fixing strip 111 will drive the fixing block 205 to rest against the right inner wall of the slot 116, thereby driving the auxiliary frame 112 to move to the right, thereby avoiding the situation where the second rubber plate 115 cannot be centered after contacting the flame-retardant cable, thereby avoiding the situation where the incision is skewed during the cutting process of the flame-retardant cable.

[0053] Example 3, reference Figures 1 to 8 , which is the third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a flame-retardant power cable processing method, which can straighten the flame-retardant cable that needs to be cut, thereby ensuring that the lengths of the cut cables are the same, including the flame-retardant power cable processing device in the above embodiment,

[0054] S1. Turn on the servo motor 126, the rack 127 drives the lower pressing plate 108 to move rightward, the lower pressing plate 108 pushes the clamping rod 104 downward, and the fixing bar 111 pushes the auxiliary frame 112 to the right;

[0055] S2, the first rubber plate 106 on the pressing rod 104 presses the left side of the flame-retardant cable, and at the same time the auxiliary frame 112 drives the wedge plate 113 to move downward, so that the second rubber plate 115 on the wedge plate 113 contacts the upper end of the right side of the flame-retardant cable;

[0056] S3, the rack 127 is controlled to continue to move rightward, and the ball head 110 contacts the retaining plate 109 and does not move downward any more;

[0057] S4. The auxiliary frame 112 drives the second rubber plate 115 to move rightward, thereby straightening and pressing the flame-retardant cable, thereby achieving the purpose of processing and cutting the flame-retardant cable.

[0058] The rest of the structure is the same as that of Example 2.
