Description

Technical Field

[0001] The invention belongs to the technical field of cable processing, and in particular relates to a cable crimping device for urban rail construction and a use method thereof. Background Art

[0002] Crimping is a method of achieving a permanent connection between conductors through mechanical deformation. In this process, the cable insulation is carefully stripped away to expose the inner metal conductor, such as copper or aluminum. Subsequently, a specially designed crimping tool is used to apply precise pressure to the connector and the exposed cable conductor to tightly fit the two. Such a connection not only ensures good electrical conductivity, but also provides sufficient mechanical strength.

[0003] However, when using current crimping equipment for cable crimping in actual construction, the following problems may be encountered:

[0004] First of all, the cable is composed of one or more mutually insulated conductors and an outer insulating protective layer. In urban rail transit construction, the cables used usually contain multiple mutually insulated conductors of different calibers. This design can not only meet the needs of different electrical loads, but also effectively reduce the total volume and weight of the cable, making it easier to install and maintain. Since the cables used in urban rail construction have a variety of conductor specifications, the crimping equipment must be able to adapt to a variety of calibers when crimping cables.

[0005] Secondly, affected by the diversity of cables, in order to ensure the safety and reliability of these cables during electrical connection, they must be crimped using connectors of matching specifications. The design of each connector is customized according to specific cable size and performance requirements to ensure good electrical contact and mechanical strength. However, due to the complex and three-dimensional structure of the connector, the supporting crimping tools and equipment are not only diverse, but also relatively large in size, resulting in the problem of large space occupation when storing and managing these devices.

[0006] Finally, urban rail construction usually requires cable crimping operations at the construction site, and the supporting crimping tools and equipment are of various types and relatively large in size, resulting in construction workers having to carry crimping tools and connection terminals of various specifications when going to different work sites. These devices are not only numerous in number, but also large in size and heavy in weight, which increases the difficulty of transportation and handling.

[0007] In summary, when the existing cable crimping equipment is used in urban rail construction, it has the problems of insufficient adaptability to multiple cable specifications, high matching requirements between the connection terminals and the crimping equipment, and inconvenient storage and carrying of the equipment. Summary of the invention

[0040] See also Figure 5 , through the control mechanism 24, the crimping module 2 can be suitable for crimping cable conductors of different specifications: the crimping die 22 is provided with a control mechanism 24, and the control mechanism 24 is used to control the movement of the crimping platform 221 and the crimping side platform 222; when the crimping platform 221 moves downward, the crimping side platforms 222 on both sides move away from the crimping platform 221, so that the notch of the crimping die 22 increases, so that the crimping module 2 can crimp large-diameter cable conductors; when the crimping platform 221 moves upward, the crimping side platforms 222 on both sides move close to the crimping platform 221, so that the notch of the crimping die 22 decreases, so that the crimping module 2 can crimp small-diameter cable conductors.

[0041] The first moving component and the second moving component are used to realize synchronous adjustment of the crimping platform 221 and the crimping side platform 222 to adapt to cable conductors of different specifications: the control mechanism 24 includes a first moving component and a second moving component, and the transmission direction of the first moving component and the transmission direction of the second moving component are vertically arranged; the moving end of the first moving component is connected to the crimping platform 221, and the moving end of the second moving component is connected to the crimping side platform 222.

[0046] Embodiment 2

[0047] The cable crimping device for urban rail construction, the crimping device involved in this embodiment is different from the crimping device in the first embodiment in that a replacement solution of the control mechanism 24 is provided, which is as follows:

[0048] See also Figure 5The control mechanism 24 includes a connecting vessel 241 and a third moving component. The connecting vessel 241 is a three-port connecting vessel 241 and is arranged in an inverted "T" shape. The connecting vessel 241 includes a first connecting port located on both sides and a second connecting port located at the top. The first connecting port is movably connected to the crimping side platform 222, and the second connecting port is movably connected to the crimping platform 221; the moving end of the third moving component is connected to the crimping side platform 222 or the crimping platform 221. The mechanical linkage effect of the connecting vessel 241 is used to achieve synchronous adjustment of the size of the crimping die 22. This design simplifies the complexity of the control system and improves the adjustment accuracy and response speed.

[0049] The advantages of the control mechanism 24 in this embodiment compared with the control mechanism 24 in the first embodiment are as follows:

[0050] The control mechanism 24 in the first embodiment controls the movement of the crimping platform 221 and the crimping side platform 222 respectively through the first moving component (vertical transmission) and the second moving component (horizontal transmission). Allowing the movement of the crimping platform 221 and the crimping side platform 222 to be adjusted independently provides higher flexibility and can more accurately adapt to the needs of cable conductors of different specifications; at the same time, since the two moving components are responsible for different directions respectively, the delay in the mechanical linkage is reduced, so that the equipment has a faster response speed during the adjustment process, and the work efficiency is improved. Moreover, the function of each moving component is relatively independent. If one of the components fails, it can be repaired or replaced separately without affecting the operation of the entire system, reducing the maintenance cost and complexity. It is more suitable for application scenarios that require high precision, fast response and flexible adjustment, especially in the case of frequent switching of cable conductors of multiple specifications. Its advantage of independent adjustment can provide better adaptability and crimping quality.

[0051] The control mechanism 24 in this embodiment adopts a three-port connecting vessel 241 (in an inverted "T" shape) design, connecting the movements of the crimping platform 221 and the crimping side platform 222 through a connecting vessel 241, simplifying the mechanical structure and reducing the number of parts; at the same time, the mechanical linkage effect of the connecting vessel 241 ensures that the movements of the crimping platform 221 and the crimping side platform 222 are completely synchronized, avoiding errors that may be caused by independent adjustment, and further improving the accuracy and stability of crimping. Moreover, only one point (crimping side platform 222 or crimping platform 221) needs to be controlled by the third moving component to adjust the size of the entire crimping die 22, making the operation more intuitive and convenient, reducing training time and learning curve. It is more suitable for occasions that pursue simple structure, cost-effectiveness and ease of operation. Its compact design and synchronous adjustment characteristics can significantly improve work efficiency and reduce maintenance costs.

[0052] Embodiment 3

[0053] The cable crimping device for urban rail construction, the crimping device involved in this embodiment is different from the crimping device in the first embodiment in that a replacement solution of the side pressure mechanism 23 is provided as follows:

[0054] See also Figure 7 The side pressure piece 231 has a second inclined surface 235 on the side facing the crimping platform 221; the side pressure mechanism 23 also includes a fifth moving component 236, the transmission direction of the fifth moving component 236 is perpendicular to the length direction of the side pressure piece 231, and the moving end of the fifth moving component 236 is connected to the side pressure piece 231; when the side pressure piece 231 on the fifth moving component 236 moves, the second inclined surface 235 acts on the crimping piece, allowing the crimping piece to bend again to complete the crimping of the cable.

[0055] Compared with the side pressure mechanism 23 in the first embodiment, the advantages of this embodiment are as follows:

[0056] The side pressure piece 231 in the first embodiment is rotatably set on the crimping side platform 222 at one end close to the crimping platform 221, and the rotation of the side pressure piece 231 is driven by the first control piece 233 (with a first inclined surface 234) on the fourth moving component 232; the precise control of the angle of the side pressure piece 231 can be achieved, which is suitable for crimping pieces of different shapes and sizes and has high adaptability; at the same time, since the side pressure piece 231 applies pressure by rotation, the pressure can be kept evenly distributed during the crimping process, avoiding poor crimping or conductor damage caused by excessive local pressure, and ensuring good electrical contact and mechanical strength.

[0057] Since the length of the side pressure piece 231 in the first embodiment determines its rotation radius, the length of the side pressure piece 231 will directly affect the bending angle and strength. A longer side pressure piece 231 can provide a greater lever effect when rotating, and can apply a greater torque, making the crimping piece easier to bend, but it may also cause excessive bending or uneven pressure distribution, especially when dealing with thicker or harder cable conductors; a shorter side pressure piece 231 may not be able to provide sufficient torque, resulting in insufficient bending effect, especially for larger diameter cable conductors, which may require higher pressure to complete effective crimping.

[0058] The side pressure piece 231 in this embodiment has a second inclined surface 235 on the side facing the crimping platform 221, and is directly linearly moved through the fifth moving component 236; the mechanical structure is simplified, the number of moving parts is reduced, the stability and reliability of the system are improved, and the possibility of failure is reduced; and the linear movement design makes the movement of the side pressure piece 231 more direct and rapid, reduces the intermediate conversion links, and improves the crimping efficiency. The operator only needs to control the fifth moving component 236 to complete the side pressure action, and the operation is more intuitive and convenient.

[0059] The side pressure piece 231 in this embodiment is directly moved linearly through the fifth moving assembly 236, so that the movement path of the side pressure piece 231 is fixed and is not affected by the length of the side pressure piece 231. Since the movement of the side pressure piece 231 is linear, it can maintain a relatively constant pressure distribution during the entire crimping process, avoiding the problem of inconsistent bending angle and force caused by the change in the length of the side pressure piece 231; the linear movement design enables the side pressure mechanism 23 to more stably cope with cable conductors of different specifications, ensuring that each crimping can achieve the expected effect, which is particularly suitable for use in construction environments where cables of multiple specifications are frequently switched.

[0060] Embodiment 4

[0061] In order to solve the above technical problems, the second technical solution of the present invention is a method for using a cable crimping device for urban rail construction, and the cable crimping device for urban rail construction described in the first technical solution is applied; the method for using comprises:

[0062] S1 Preparation and adjustment: Select a suitable crimping piece according to the diameter of the cable conductor to be crimped, and adjust the crimping punch 21 and the crimping die 22 to the appropriate position through the control mechanism 24.

[0063] S2 initial bending: place the crimping sheet into the sheet placement groove 223, start the sixth moving assembly 211, and make the crimping convex die 21 cooperate with the crimping concave die 22 to perform initial bending on the crimping sheet to form a placement groove.

[0064] S3 Placing the conductor: Carefully place the conductor of the cable on the formed placement groove.

[0065] S4 crimping: activating the side pressing mechanism 23 through the control mechanism 24 so that the side pressing member 231 bends the crimping piece again, and finally completing the crimping of the cable.

[0066] S5 final compression and compaction: by moving the crimping punch 21 toward the crimping die 22 and the crimping side platforms 222 on both sides toward the crimping platform 221, further pressure is applied to make the crimping sheet wrap the cable conductor more tightly, thereby improving the electrical contact performance and mechanical strength.

[0067] In addition, as common knowledge in the industry, the first moving assembly, the second moving assembly, the third moving assembly, the fourth moving assembly 232, the fifth moving assembly 236, the sixth moving assembly 211 and the seventh moving assembly 34 mentioned above can be a linear guide rail system consisting of a fixed guide rail and a slider sliding thereon, a ball screw, a gear rack, a cylinder and a hydraulic cylinder, etc. The above is common knowledge, so the principle and structure will not be described in detail.

[0068] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
