Description

Technical Field

[0001] The utility model relates to the technical field of alloy wire oxidation, in particular to a placing rack for alloy wire oxidation. Background Art

[0002] The oxidation treatment of alloy wire is an important part in the production of electrical contact materials. During the production process of alloy wire, in order to improve the internal structure of the material, achieve complete oxidation, and improve its processing performance, some high-temperature oxidation methods are often required to meet the above requirements. However, during the oxidation treatment of alloy wire, in order to accelerate the oxidation efficiency and increase the output, the wires are often stacked together for oxidation, resulting in poor oxidation uniformity of the alloy due to the uneven heat-receiving surface of the material. Summary of the Invention

[0003] In order to solve the problem that the existing alloy wires are stacked together for oxidation, resulting in poor oxidation uniformity of the alloy wires due to the uneven heat-receiving surface of the material, the utility model provides a placing rack for alloy wire oxidation. The coiled alloy wires are placed in the trays on the partition plates of the rack, so as to separate multiple trays of alloy wires and avoid contact between the alloy wires. At the same time, the first ventilation holes opened on the partition plates and the second ventilation holes opened on the trays improve the heat contact of the alloy wires in the oxidation furnace, thereby improving the uniformity of heat received by the alloy wires during oxidation.

[0004] In order to achieve the above purpose, the technical solution of the utility model is as follows:

[0005] A placing rack for alloy wire oxidation is placed in an oxidation furnace and includes a chassis. A rack is fixed on the chassis, and a cover plate is fixed at one end of the rack away from the chassis. A plurality of partition plates are fixed on the rack, and the partition plates are located between the chassis and the cover plate. A plurality of first ventilation holes are evenly opened on the partition plates. A tray is placed on each partition plate. The tray includes a bottom plate and side plates surrounding the outer periphery of the bottom plate. A plurality of second ventilation holes are evenly opened on the bottom plate and the side plates. A first through hole is opened on the bottom plate, and a limiting cylinder is fixed on the bottom plate and is arranged corresponding to the first through hole. A coiled alloy wire is placed in the tray, and the alloy wire is placed between the limiting cylinder and the side plates. A second through hole corresponding to the first through hole is opened on the partition plate. The side plates surrounding the outer periphery of the bottom plate are connected end to end to form a cylindrical structure. The sizes of the first through hole and the second through hole are the same, realizing the up-and-down transfer of heat in each tray and being able to better improve the uniformity of heat received by the alloy wires during oxidation.

[0006] Furthermore, the cross-sections of the partition plates and the side plates of the trays are both circular.

[0007] Further, the size of the isolation plate is equal to that of the bottom plate of the material tray. The material rack includes multiple fixing columns, and all the multiple fixing columns are located on the same side of the middle part of the isolation plate. The arrangement of the fixing columns ensures the stability of the placement of the material tray, and at the same time, all the multiple fixing columns being located on the same side of the middle part of the isolation plate ensures that the material tray will not be blocked when placed on the isolation plate.

[0008] Further, the cross-sections of the isolation plate and the side plate of the material tray are both square.

[0009] Further, the lower end surfaces of multiple isolation plates are attached to the upper end surfaces of the side plates of the material tray, and the upper end surface of the highest material tray is attached to the lower end surface of the cover plate. This improves the heat preservation effect of the material tray, and further improves the oxidation effect of the alloy wire.

[0010] Further, multiple isolation plates are evenly fixed on the material rack, and the distance range between two adjacent isolation plates is 150 - 250 mm.

[0011] Further, the diameter range of the isolation plate is 200 - 500 mm.

[0012] Further, slots are provided on the side plates of the material tray. This facilitates subsequent access.

[0013] Through the above technical solutions, the beneficial effects of the present utility model are as follows: The present utility model places the coiled alloy wire on the material trays on multiple isolation plates of the material rack, thereby separating multiple trays of alloy wire to avoid contact between the alloy wires. The first ventilation holes provided on the isolation plates and the second ventilation holes provided on the material trays ensure continuous contact between the alloy wire and heat in the oxidation furnace, improving the oxidation effect of the alloy wire. At the same time, the cooperation between the second through holes provided on the isolation plates and the first through holes on the material trays realizes heat transfer between the upper and lower material trays, which can better improve the uniformity of heat absorption during the oxidation of the alloy wire.

A plurality of horizontal partition plates 4 are welded and fixed on the rack 2. The partition plates 4 are located between the chassis 1 and the cover plate 3. A plurality of first ventilation holes 5 are evenly opened on the partition plates 4. A tray 6 is placed on each partition plate 4;

[0021] In this embodiment, the placement rack is placed in the oxidation furnace from the upper opening of the oxidation furnace by means of hoisting. The hoisting structure of the placement rack is the disc-shaped structure 8 at the upper end of the placement rack; 4 horizontal partition plates 4 are evenly fixed on the rack 2. The distance range between two adjacent partition plates 4 is 150 - 250 mm, preferably 150 mm, 200 mm, and 230 mm, which is applicable to different specifications of disc-shaped alloy wires 10. The overall height of the placement rack needs to be less than the height of the oxidation furnace.

[0022] The tray 6 includes a bottom plate and side plates surrounding the outer periphery of the bottom plate. A plurality of second ventilation holes 7 are evenly opened on the bottom plate and the side plates; in this embodiment, the side plates surrounding the outer periphery of the bottom plate are connected end to end to form a cylindrical structure. The first ventilation holes 5 opened on the partition plates 4 and the second ventilation holes 7 opened on the tray 6 ensure the continuous contact between the alloy wire 10 and heat in the oxidation furnace, improving the oxidation effect of the alloy wire 10.

[0023] A first through hole is opened on the bottom plate. A limiting cylinder 9 is fixed on the bottom plate. The limiting cylinder 9 is arranged corresponding to the first through hole. A disc-shaped alloy wire 10 is placed in the tray 6. The alloy wire 10 is placed between the limiting cylinder 9 and the side plates. A second through hole 11 corresponding to the first through hole is opened on the partition plate 4. In this embodiment, the first through hole and the second through hole 11 are of the same size. When the tray 6 is placed on the partition plate 4, the first through hole and the second through hole 11 overlap up and down, realizing the heat transfer between the upper and lower trays 6.

[0024] In this embodiment, the cross-sections of the partition plate 4 and the side plates of the material tray 6 are both circular. The diameter range of the partition plate 4 is 200 - 500 mm, preferably 300 mm, 400 mm, 440 mm, and 450 mm. The sizes of the bottom plates of the partition plate 4 and the material tray 6 are equal. The material rack 2 includes multiple fixing columns, and in order to ensure that the access of the material tray 6 on the partition plate 4 is not blocked, the multiple fixing columns are all located on the same side of the middle of the partition plate 4.

[0025] In this embodiment, the materials of the chassis 1, the material rack 2, the cover plate 3, the partition plate 4, the material tray 6, and the limiting cylinder 9 are 316L or 310s.

[0026] In another implementable manner, the lower end surfaces of the multiple partition plates 4 are attached to the upper end surfaces of the side plates of the material tray 6, and the upper end surface of the highest material tray 6 is attached to the lower end surface of the cover plate 3. The material trays 6 on the multiple partition plates 4 are attached to each other, improving the heat preservation effect of the material trays 6, and thus improving the oxidation effect of the alloy wire 10.

[0027] As an implementable manner, the cross-sections of the partition plate 4 and the side plates of the material tray 6 are both square.

[0028] As an implementable manner, a slot 12 is provided on the side plate of the material tray 6. After the alloy wire 10 is oxidized, an operator hooks the slot 12 with a tool, which is convenient for taking out the material tray 6 from the placement rack.

The oxidation furnace operates to oxidize the alloy wire 10 on the placement rack. After oxidation, the placement rack can be taken out of the oxidation furnace by the hoisting device.
