Description

Technical Field

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

[0002] Crimping is a method of creating a permanent connection between conductors through mechanical deformation. During this process, a small section of the cable's insulation is carefully stripped back to expose the underlying metal conductor, such as copper or aluminum. A specially designed crimping tool then applies precise pressure to the connector and exposed cable conductor, forcing them together. This connection ensures both good electrical conductivity and mechanical strength.

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

[0004] First, a cable consists of one or more mutually insulated conductors surrounded by an insulating protective layer. In urban rail transit construction, cables typically contain multiple, mutually insulated conductors of varying diameters. This design not only meets the demands of varying electrical loads but also effectively reduces the overall cable size and weight, facilitating installation and maintenance. Because cables used in urban rail construction have a wide variety of conductor specifications, crimping equipment must be capable of adapting to a variety of diameters.

[0005] Secondly, due to the diverse nature of cables, crimping them with connectors of matching specifications is essential to ensure safe and reliable electrical connections. Each connector is custom-designed to meet specific cable dimensions and performance requirements, ensuring good electrical contact and mechanical strength. However, the complex and three-dimensional structure of the connectors necessitates a wide variety of crimping tools and equipment, which are both bulky and require significant storage space.

[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. As a result, construction workers must carry crimping tools and connection terminals of various specifications when going to different work sites. These devices are not only numerous, but also large in size and heavy in weight, which increases the difficulty of transportation and handling.

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

Whether it's large or small diameter cables, the machine can automatically or manually adjust to the most appropriate crimp size, ensuring optimal crimping results every time.

[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 recess 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 recess of the crimping die 22 decreases, so that the crimping module 2 can crimp small-diameter cable conductors.

[0041] The first movable assembly and the second movable assembly are used to achieve 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 movable assembly and a second movable assembly, and the transmission direction of the first movable assembly and the transmission direction of the second movable assembly are arranged vertically; the moving end of the first movable assembly is connected to the crimping platform 221, and the moving end of the second movable assembly is connected to the crimping side platform 222.

One end of the side pressure piece 231 is rotatably mounted on the crimping side platform 222, and the movable end of the fourth movable assembly 232 is provided with a first control piece 233 having a first inclined surface 234.

Under the action of the connecting rod 216 and the limiting slide rail 215, when the crimping side platform 222 moves, the first protrusion 213 and the second protrusion 214 move accordingly, so that the crimping punch 21 and the crimping die 22 bend the crimping piece to form a placement groove for the crimping piece.

[0046] Example 2

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

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

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

[0050] The control mechanism 24 in Example 1 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 greater 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 each responsible for a different direction, the delay in the mechanical linkage is reduced, so that the equipment has a faster response speed during the adjustment process, thereby improving work efficiency. 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 maintenance costs 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. The advantage of its independent adjustment can provide better adaptability and crimping quality.

[0051] The control mechanism 24 in this embodiment adopts a three-port connecting tube 241 (in the shape of an inverted "T") to connect the movements of the crimping platform 221 and the crimping side platform 222 through a connecting tube 241, simplifying the mechanical structure and reducing the number of parts. At the same time, the mechanical linkage effect of the connecting tube 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 (the crimping side platform 222 or the 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 easy operation. Its compact design and synchronous adjustment characteristics can significantly improve work efficiency and reduce maintenance costs.

[0052] Example 3

[0053] The cable crimping device for urban rail construction is different from the crimping device in the first embodiment in that a replacement solution for 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, causing the crimping piece to bend again to complete the crimping of the cable.

[0055] The advantages of the side pressure mechanism 23 in this embodiment compared to the first embodiment are as follows:

[0056] The side pressure piece 231 in Example 1 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, and it is suitable for crimping pieces of different shapes and sizes, with 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 directly affects the bending angle and force. A longer side pressure piece 231 can provide a greater leverage effect when rotating, and can apply a greater torque, making it easier to bend the crimping piece. However, it may also cause excessive bending or uneven pressure distribution, especially when processing thicker or harder cable conductors. A shorter side pressure piece 231 may not provide sufficient torque, resulting in insufficient bending effect. In particular, for larger diameter cable conductors, higher pressure may be required to complete effective crimping.

[0058] In this embodiment, the side pressure member 231 has a second inclined surface 235 on the side facing the crimping platform 221, which is directly linearly moved by a fifth movable assembly 236. This simplifies the mechanical structure, reduces the number of moving parts, improves system stability and reliability, and reduces the likelihood of failure. Furthermore, the linear motion design makes the side pressure member 231 more direct and rapid, eliminating intermediate conversion steps and improving crimping efficiency. The operator only needs to control the fifth movable assembly 236 to complete the side pressure action, making operation more intuitive and convenient.

[0059] The side pressure member 231 in this embodiment is directly moved linearly via the fifth moving assembly 236, so that the movement path of the side pressure member 231 is fixed and is not affected by the length of the side pressure member 231. Since the movement of the side pressure member 231 is linear, it can maintain a relatively constant pressure distribution throughout the crimping process, avoiding the problems of inconsistent bending angles and forces caused by changes in the length of the side pressure member 231. The linear movement design enables the side pressure mechanism 23 to more stably handle cable conductors of different specifications, ensuring that each crimping can achieve the desired effect. It is particularly suitable for use in construction environments where multiple cable specifications are frequently switched.

[0060] Example 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, which uses the cable crimping device for urban rail construction described in the first technical solution; the method of use includes:

[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 pressure mechanism 23 through the control mechanism 24 so that the side pressure member 231 bends the crimping piece again, and finally completing the crimping of the cable.

[0066] S5 final 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 piece wrap the cable conductor more tightly, thereby improving the electrical contact performance and mechanical strength.

[0067] Furthermore, as is common knowledge in the industry, the first moving assembly, second moving assembly, third moving assembly, fourth moving assembly 232, fifth moving assembly 236, sixth moving assembly 211, and seventh moving assembly 34 mentioned above can be linear guide systems consisting of fixed guide rails and sliders sliding thereon, ball screws, rack and pinion gears, pneumatic cylinders, hydraulic cylinders, etc. The above is common knowledge, and therefore their principles and structures 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 implementation methods. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
