Description

Technical Field

[0001] The utility model relates to the technical field of cored wire production, in particular to a production unit for double-layer seamless cored wires. Background Art

[0002] Core wire is formed by wrapping alloy powder around a steel strip. Depending on the type of alloy powder, it can be categorized as calcium-silicon cored wire, calcium-iron cored wire, and calcium-aluminum cored wire. The seams of the steel strips can be connected by folding the edges together to form a joint. Alternatively, the seams can be welded together. Core wire with welded steel strips is called seamless core wire. Double-layer seamless core wire has at least one seam of the double-layer steel strips welded together.

[0003] Double-layer seamless cored wire requires high-frequency welding. High-frequency welding machines offer high welding efficiency, but the steel strip heats up rapidly during welding, necessitating cooling of the cored wire after welding. For example, the utility model patented with publication number CN217173782U, which describes a silicon-magnesium-calcium alloy cored wire production device, can cool the cored wire. However, when the cored wire is removed from the cooling tank, residual water remains on the surface, causing the water in the cooling tank to be continuously removed. Traditionally, manual wiping of this residual water is inefficient and labor-intensive. Using a fixed rag or towel to wipe the cored wire quickly causes the rag or towel to wear and damage.

[0024] The following further details the present utility model in conjunction with embodiments.

[0025] Specific embodiments of the production unit for double-layer seamless cored wire provided by the present utility model:

[0026] Please refer to Figures 1-4 , a production unit for double-layer seamless cored wire, including a cooling tank 1 for containing cooling water for the cored wire 14 to pass through; at the end of the cooling tank 1 where the cored wire 14 is output, there are two sponge plates 2 for clamping the cored wire 14. The shapes of the sponge plates 2 are both rectangular plate-shaped. The two sponge plates 2 are placed corresponding to each other up and down. The cored wire 14 passes through between the two sponge plates 2 perpendicular to the length direction of the sponge plates 2. The two sponge plates 2 form a wrap around the cored wire 14, effectively wiping off most of the moisture on the outside of the cored wire 14 and preventing the moisture from dripping outside the cooling tank 1.

[0027] Above the end of the cooling tank 1 where the cored wire 14 is output, there is a portal frame 9. Inside the portal frame 9, there are two support plates 7, upper and lower. The two support plates 7 respectively support the two sponge plates 2; the sponge plates 2 are located on the opposite sides of the two support plates 7.

[0028] The support plate 7 is located above the cooling tank 1. The bolt 10 passes through the side wall of the portal frame 9 and is threadedly connected to the end of the support plate 7. Bolts 10 are threadedly connected to both ends of the support plate 7. The portal frame 9 is provided with through holes that cooperate with the bolts 10. The bolt 10 connection structure enables the support plate 7 and the sponge plate 2 to be detachable, which facilitates the regular replacement of the sponge plate 2. The connection method between the sponge plate 2 and the support plate 7 is bonding. When replacing the sponge plate 2, remove the support plate 7 and take it out from the portal frame 9. First, scrape off the old sponge plate 2, and then paste a new sponge plate 2.

[0029] In some embodiments, the through holes provided on the portal frame 9 that cooperate with the bolts 10 are vertical strip-shaped holes 11. The through holes corresponding to at least one end of the support plate 7 are strip-shaped holes 11, so that the vertical position of one support plate 7 can be adjusted, and thus the distance between the two sponge plates 2 can be adjusted.

[0030] A bi-directional reciprocating lead screw 5 is rotatably installed inside the portal frame 9. The bi-directional reciprocating lead screw 5 is parallel to the length direction of the sponge plate 2. A motor 6 is installed outside the portal frame 9. The output shaft of the motor 6 is connected to the bi-directional reciprocating lead screw 5 to drive the bi-directional reciprocating lead screw 5 to rotate.

[0031] A sliding seat 3 is provided inside the portal frame 9. There is a gap between the sliding seat 3 and the inner side of the portal frame 9. The bi-directional reciprocating lead screw 5 passes through the sliding seat 3 and meshes with the sliding seat 3. Two guide rods 8 are connected to the inner side of the portal frame 9. The guide rods 8 are located above the cooling tank 1. The two guide rods 8 are parallel to the bi-directional reciprocating lead screw 5 and are symmetric on both sides of the bi-directional reciprocating lead screw 5. The guide rods 8 all pass through the sliding seat 3, and the sliding seat 3 slides along the guide rods 8.

[0032] When the motor 6 rotates, it drives the bi-directional reciprocating lead screw 5 to rotate. The rotation of the bi-directional reciprocating lead screw 5 enables the sliding seat 3 to reciprocate under the guidance of the guide rods 8.

[0033] An output wire groove wheel 4 for supporting the core wire 14 is rotatably installed under the sliding seat 3. Two output wire groove wheels 4 are provided. The two output wire groove wheels 4 are respectively located on both sides of the sponge plate 2. The output wire groove wheels 4 on both sides move horizontally with the sliding seat 3, jointly causing the core wire 14 to displace horizontally and changing the contact position between the sponge plate 2 and the core wire 14.

[0034] If the cored wire 14 passes through the fixed position of the sponge plate 2, the sponge plate 2 will be quickly worn out. In this embodiment, the output wire sheave 4 reciprocates under the drive of the sliding seat 3. The output wire sheave 4 drives the cored wire 14 to reciprocate horizontally, so that the cored wire 14 contacts the sponge plate 2 at various places in a cycle, avoiding the single-position wear of the sponge plate 2 by the cored wire 14 and extending the service life of the sponge plate 2. On the other hand, the cored wire 14 can also squeeze the sponge plate 2 to reduce the moisture inside the sponge plate 2, avoid a large amount of moisture stored in the sponge plate 2, and thus is beneficial to the sponge plate 2 to wipe off the moisture on the outer side of the cored wire 14.

[0035] In this embodiment, an input wire sheave 12 is provided on the upper side of the end of the cored wire 14 input into the cooling tank 1; an intermediate wire sheave 13 is provided at the bottom inside the cooling tank 1; the cored wire 14 bypasses from the upper side of the input wire sheave 12, then bypasses from the lower side of the intermediate wire sheave 13, then passes from the upper side of an output wire sheave 4, passes through between two sponge plates 2, and finally outputs from the upper side of the other output wire sheave 4. The intermediate wire sheave 13 ensures that the cored wire 14 is conveyed through the lower part of the cooling tank 1, so that the water in the cooling tank 1 effectively cools the cored wire 14.

[0036] In this embodiment, the output wire sheave 4, the input wire sheave 12, and the intermediate wire sheave 13 are all deep-groove sheaves. There are annular grooves on the outer sides of the sheaves. The radial depth of the annular grooves is more than twice the outer diameter of the cored wire 14. While guiding the cored wire 14, the deep-groove sheaves can prevent the cored wire 14 from coming out, and at the same time ensure that the output wire sheave 4 can drive the cored wire 14 to swing against the resistance of water, thereby realizing the horizontal movement of the cored wire 14 between the sponge plates 2.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still make modifications to the technical solutions described in the foregoing embodiments without creative efforts, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
