Description

Technical Field

[0001] This invention belongs to the technical field of cable production equipment, and specifically relates to an online cable welding and crimping device. Background Technology

[0002] Wires and cables are wire products used to transmit electrical (magnetic) energy, information, and realize the conversion of electromagnetic energy. With the advancement and development of technology, the market demand for special cables is increasing. From traditional insulation coating to metal tape coating, the requirements for wire and cable production are also changing according to different customer applications and usage scenarios.

[0003] In the production process of metal-coated cables, the metal strip is cut to the required specifications according to the size of the conductor core to be coated. The metal strip is then gradually bent into a tubular shape through a flared mold and wrapped around the conductor core. After the metal strip is joined together, it is welded online to form a closed metal tube. During the joining process, the metal strip can easily trap burrs, flash, and other foreign objects generated during the wrapping process. If these burrs or other foreign objects are encountered during subsequent online welding, they can cause defects such as burn-through, gaps, and black spots, resulting in product quality defects. Furthermore, manual repair welding is required, severely impacting production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an online cable welding and crimping device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] An online cable welding and crimping device, comprising:

[0007] The mold frame is used to support the entire device;

[0008] The first mold base and the second mold base are respectively disposed on the mold frame;

[0009] The first horn mold and the second horn mold are respectively embedded in the first mold base and the second mold base, so that the wrapped conductor cores can pass through in sequence;

[0010] An L-shaped adjustment bracket is installed above the second mold base;

[0011] The sleeve is hinged to the L-shaped adjusting frame via a sleeve seat, and the sleeve has a guide groove inside.

[0012] A connecting rod, one end of which is slidably connected to the sleeve, and the other end of which is equipped with a pressure wheel;

[0013] A compression spring, disposed between the connecting rod and the sleeve, is used to provide a continuous clamping force on the wire core by the pressure wheel;

[0014] The pressure roller, connected to the connecting rod via a rotating shaft, can rotate as the conductor moves and is used to flatten burrs or flash on the surface of the conductor core.

[0015] The pressure roller is mounted on the rotating shaft via a bearing, and the bearing has collars at both ends to limit the axial displacement of the bearing.

[0016] An adjusting nut is provided between the connecting rod and the sleeve to adjust the preload of the compression spring, thereby controlling the degree of pressure of the pressure wheel on the wire core.

[0017] The connecting rod is connected to the L-shaped adjusting frame through a connecting rod seat. The connecting rod seat is provided with a sliding sleeve to guide the connecting rod to slide smoothly.

[0018] The L-shaped adjustment frame is provided with an adjustment groove and is connected to the second mold base by an adjustment screw, so that the L-shaped adjustment frame can be adjusted relative to the second mold base, thereby changing the relative position of the pressure roller and the wire core.

[0019] The pressure roller is an arc-shaped roller, and its outer circumference matches the shape of the surface of the wrapped conductor core to improve the pressure effect.

[0020] One end of the rotating shaft is provided with an external thread, which cooperates with a nut to fix the pressure wheel, and the other end is provided with a nut for easy installation and disassembly.

[0021] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0022] This invention solves the sealing problem between the shell and the high-voltage insulation components by modifying the internal and external structure of the insulation box, adding a sealing ring and filling sealing material between the box body and the electric field shell plate, and adding a casting material seal on the outside. It also solves the problem of frequent cracking caused by ash accumulation and condensation of acid in the internal insulation box of the electrostatic precipitator under complex high-temperature flue gas conditions, which leads to condensation and creepage of the cathode ceramic basin. This greatly improves the service life of the cathode ceramic basin. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0029] like Figure 1-3 As shown, the online cable welding and crimping device of the present invention includes a mold frame, a horn mold, a mold base, a crimping wheel, a connecting rod, a compression spring, a sleeve, an L-shaped adjusting bracket, an adjusting screw, a sleeve base, a fixing screw, a sliding sleeve, a connecting rod base, a bushing, a rotating shaft, a bearing, and a nut. A first mold base 4 and a second mold base 14 are placed on the mold frame 1. A first horn mold 3 is placed in the first mold base 4 along the movement direction of the wrapped conductor core 2, and a second horn mold 14 is placed in the second mold base 13 along the movement direction of the wrapped conductor core 2.

[0030] An L-shaped adjustment frame 10 is provided above the second mold base 13. The L-shaped adjustment frame 10 is hinged to the sleeve 9 through the sleeve base 16 and the fixing screw 17. The sleeve 9 has a guide groove inside, and the small end of the connecting rod 6 is slidably connected to the sleeve 9.

[0031] The other end of the connecting rod 6 is threadedly connected to the nut 23 via a rotating shaft 21 to fix the pressure wheel 5. A bearing 22 is installed inside the pressure wheel 5. A collar 20 is installed at both ends of the bearing 22. One end of the rotating shaft 21 is externally threaded and connected to the internal thread of the nut 23, and the other end is a nut.

[0032] A compression spring 8 is provided between the small end of the connecting rod 6 and the sleeve 9. One end of the compression spring 8 is fixed by the adjusting nut 7. The connecting rod 6 is connected to the L-shaped adjusting frame 10 through the connecting rod seat 19. A sliding sleeve 18 is installed in the connecting rod seat 19 to ensure that the connecting rod 6 can move smoothly.

[0033] The L-shaped adjustment frame 10 is provided with an adjustment groove 11 and is connected to the second mold base 13 by an adjustment screw 12. The L-shaped adjustment frame 10 can be adjusted through the adjustment groove 11 to make the pressing wheel as close as possible to the second mold base 13, so as to ensure the pressing effect of the pressing wheel 5 before the metal strip seam is closed.

[0034] The pressure roller 5 is an arc-shaped pressure roller, and the pressure roller 5 can be replaced according to the diameter of the conductor core being wrapped.

[0035] During the process, the metal strip is cut to the required production specifications according to the size of the wrapped conductor core. The metal strip is gradually bent into a tubular shape through the horn mold and wrapped with the required wrapped conductor core.

[0036] Furthermore, the present invention provides an online cable welding and pressing device, wherein the pressing wheel 5 can be replaced according to the winding conductor core, and the pressing wheel can be brought as close as possible to the second mold base by adjusting the left and right of the adjusting groove on the L-shaped adjusting frame.

[0037] Furthermore, the crimping roller can flatten burrs, flash, and other foreign objects formed during the wire core wrapping process, completing the seam of the metal strip immediately after crimping. Then, through subsequent online welding, a closed metal tube is formed, effectively avoiding defects such as weld penetration and gaps caused by burrs, flash, and other foreign objects encountered during online welding. This avoids product quality defects, reduces the need for manual re-welding, and improves production efficiency.
