Description
Technical Field
[0001] This application relates to the technical field of ultra-high voltage electromagnetic wire processing, and specifically to an ultra-high voltage electromagnetic wire insulation layer molding device. Background Art
[0002] Ultra-high voltage electromagnetic wires generally refer to transmission lines used to transmit ultra-high voltage electricity. These transmission lines are usually supported by high-voltage transmission towers or poles, and electricity is transmitted from power generation stations to users in various places through cables or wires. These lines adopt special insulating materials and structural designs to ensure the safe and reliable transmission of high-voltage electricity.
[0003] In the ultra-high voltage electromagnetic wire processing process, it is necessary to configure the insulation layer on the outside of the ultra-high voltage electromagnetic wire by molding. Currently, in the existing technology, a whole mold for the straight part and the turning part support of the electromagnetic wire coil model is used, and pressure is applied through the inner cavity of the combined mold to fit the outer shape of the electromagnetic wire to complete the molding of the insulation layer. However, during the molding process, the electromagnetic wire needs to be heated, and the heating of the electromagnetic wire will cause the insulation layer to shrink, which will in turn cause the loosening of the molding fixture and reduce the fitting degree of the insulation layer. In view of the above-mentioned problems in the existing technology, an ultra-high voltage electromagnetic wire insulation layer molding device is proposed to solve the above-mentioned problems. Utility Model Content
[0004] In view of the deficiencies of the existing technology, this application provides an ultra-high voltage electromagnetic wire insulation layer molding device, which has the advantages of adapting to the clamping loosening caused by the shrinkage of the insulation layer during the heating of the electromagnetic wire and improving the fitting degree between the mold and the electromagnetic wire.
[0005] To achieve the above object, this application provides the following technical solution: An ultra-high voltage electromagnetic wire insulation layer molding device includes a mold composed of an upper mold and a lower mold that are buckled with each other, and a C-shaped fixture placed outside the mold. The C-shaped fixture includes a C-shaped frame for support, a threaded adjustment member installed on the C-shaped frame, and a clamping block arranged on the threaded adjustment member and the C-shaped frame;
[0006] The threaded adjustment member includes a threaded rod threadedly installed at the upper end of the C-shaped frame, and an installation cylinder movably installed at one end of the threaded rod extending into the C-shaped frame. An abutting plate is also fixedly installed at the end of the threaded rod. The abutting plate is located inside the installation cylinder and is movably connected to the installation cylinder. A compression spring for pressing the clamping block is also installed inside the installation cylinder. One end of the compression spring is fixedly connected to the clamping block, and the other end is suspended inside the installation cylinder.
[0007] Further, the longitudinal sections of the upper mold and the lower mold are both in an L-shaped bent shape, and a gap is left between the bent parts of the upper mold and the lower mold facing each other to fit the electromagnetic wire.
[0008] Furthermore, an adjusting bolt is fixedly installed at one end of the threaded rod extending above the C-shaped frame.
[0009] Furthermore, a connecting member is arranged between several of the C-shaped clamps for unified connection. The connecting member includes a cross bar for supporting several of the C-shaped clamps, a connecting frame slidably connected to the cross bar, and a fastening member arranged on the connecting frame, wherein the connecting frame is fixed on the rear side surface of the C-shaped frame.
[0010] Furthermore, the fastening member includes a threaded adjusting rod threadedly installed on the connecting frame, and a friction pad fixedly installed at the end of the threaded adjusting rod extending into the connecting frame. A cavity is recessed on the inner wall of the connecting frame for storing the friction pad.
[0011] Furthermore, spring seats are fixedly installed on both side surfaces of the connecting frame, and a push spring is installed between two adjacent spring seats. The push spring pushes the two connecting frames to be arranged at intervals from each other.
[0012] Compared with the prior art, the technical solution of the present application has the following beneficial effects:
[0013] In this ultra-high voltage electromagnetic wire insulation layer molding device, by providing an inner space for the electromagnetic wire through the combination of an upper mold and a lower mold with an L-shaped cross-section, the contact tightness between the electromagnetic wire and the mold is improved. Additionally, by using two clamping blocks of a C-shaped clamp to clamp the upper mold and the lower mold together, and by configuring an installation cylinder and a compression spring at the end of the threaded rod on the clamp, the C-shaped clamp can apply a tension force through the compression spring simultaneously when clamping. During the process of the electromagnetic wire heating and causing the insulation layer to gradually shrink, the compression spring can continuously apply a force to improve the clamping effect, solving the technical problem that when the electromagnetic wire is heated, it will cause the insulation layer to shrink, thereby leading to loosening of the molding clamp and reducing the adhesion degree of the insulation layer.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present application.
[0021] Please refer to Figures 1-5 , a super high voltage electromagnetic wire insulation layer molding device in this embodiment includes a mold composed of a mutually buckled upper die 1 and a lower die 2, and a C-shaped fixture placed outside the mold. The number of C-shaped fixtures is several, and several C-shaped fixtures are evenly arranged outside the mold to provide a clamping force for the closing of the upper die 1 and the lower die 2.
[0022] In this embodiment, the longitudinal sections of the upper die 1 and the lower die 2 are both in an L-shaped bent shape, and the bent parts of the upper die 1 and the lower die 2 face each other with a gap left to fit against the electromagnetic wire, so that the closing gap between the electromagnetic wire and the upper die 1 and the lower die 2 is far away, thereby improving the contact tightness between the mold and the electromagnetic wire.
[0023] It should be noted that the C-shaped fixture includes a C-shaped frame 3 for support, a threaded adjusting member installed on the C-shaped frame 3, and a clamping block 6 provided on the threaded adjusting member and the C-shaped frame 3. The two clamping blocks 6 are corresponding in the up and down positions and are respectively used to fit against the upper die 1 and the lower die 2.
[0024] The threaded adjusting member in this embodiment includes a threaded rod 4 threadedly installed at the upper end of the C-shaped frame 3 and an installation cylinder 5 movably installed at one end of the threaded rod 4 extending into the C-shaped frame 3. The installation cylinder 5 can rotate and slide relative to the threaded rod 4, and a clamping block 6 is fixedly connected to the installation cylinder 5, and the distance between the clamping block 6 on the installation cylinder 5 and the clamping block 6 on the C-shaped frame 3 can be adjusted when the threaded rod 4 rotates to change its position relative to the C-shaped frame 3 for clamping.
[0025] In this embodiment, a contact plate 7 is also fixedly installed at the end of the threaded rod 4. The contact plate 7 is located inside the installation cylinder 5 and is movably connected to the installation cylinder 5, so that the contact plate 7 can move flexibly inside the installation cylinder 5.
[0026] It should be noted that a compression spring 8 for pressing the clamping block 6 is also installed inside the installation cylinder 5. One end of the compression spring 8 is fixedly connected to the clamping block 6, and the other end is suspended inside the installation cylinder 5, so that the abutting plate 7 can contact and squeeze the compression spring 8 during the downward pressing process.
[0027] In order to facilitate the rotation of the threaded rod 4, an adjusting bolt 9 is fixedly installed at one end of the threaded rod 4 extending above the C-shaped frame 3 in this embodiment.
[0028] In this embodiment, a connecting member is provided between several C-shaped clamps for unified connection. The connecting member includes a cross bar 11 for supporting several C-shaped clamps, a connecting frame 10 slidably connected to the cross bar 11, and a fastening member provided on the connecting frame 10. Among them, the connecting frame 10 is fixed on the rear side surface of the C-shaped frame 3, and the connecting frame 10 is slidably connected relative to the cross bar 11.
[0029] It should be noted that the fastening member includes a threaded adjusting rod 12 threadedly installed on the connecting frame 10 and a friction pad 13 fixedly installed at the end of the threaded adjusting rod 12 extending into the connecting frame 10. A cavity is recessed on the inner wall of the connecting frame 10 for storing the friction pad 13. When the friction pad 13 extends into the connecting frame 10 and fits against the cross bar 11, the position of the connecting frame 10 relative to the cross bar 11 can be restricted.
[0030] In order to improve the uniformity of the distribution of the C-shaped clamps on the cross bar 11, spring seats 14 are fixedly installed on both side surfaces of the connecting frame 10 in this embodiment. A push spring 15 is installed between two adjacent spring seats 14. The push spring 15 pushes the two connecting frames 10 to be arranged at intervals from each other, so that the C-shaped clamps are evenly distributed on the cross bar 11.
[0031] The working principle of the above embodiment is as follows:
[0032] By placing the electromagnetic wire in the mold closing gap between the upper mold 1 and the lower mold 2 to complete the internal installation, move the cross bar 11 to move several C-shaped clamps to one side surface of the mold. By rotating the adjusting bolt 9, the adjusting bolt 9 drives the fixedly connected threaded rod 4 to rotate. The threaded rod 4 extends toward the inside of the C-shaped frame 3 under the rotational thread fit relative to the C-shaped frame 3. At this time, both clamping blocks 6 are attached to the outside of the mold. Continuously adjust the threaded rod 4, so that the threaded rod 4 drives the abutting plate 7 located inside the installation cylinder 5 to continuously squeeze the compression spring 8, so that the compression spring 8 exerts a spring force, so that the clamping block 6 below the installation cylinder 5 can move in a direction away from the threaded rod 4. When the electromagnetic wire heats up and shrinks, it will be continuously clamped and pressurized under the opening force of the spring.
