Description

Technical Field

[0001] This utility model relates to the field of copper processing technology, and in particular to a vacuum annealing rack for copper coils. Background Technology

[0002] The copper strip undergoes annealing to improve its performance; the annealing of copper strip coils usually involves placing the copper coil on the support crossbar of the annealing rack and then placing it in the annealing furnace for annealing.

[0003] The existing annealing frame structure mainly includes a chassis and columns, as well as a set of crossbars set on the columns. The set of crossbars are staggered, and the center hole of the copper strip coil is fitted onto each crossbar. Multiple copper strip coils can be positioned on each annealing frame to improve annealing efficiency. However, the copper strip coils are heavy, and it is inconvenient to remove them from the crossbars after annealing. Even with hoisting operations, it is not convenient to move the copper strip coils along the axial direction of each crossbar to remove them because the crossbars are oriented differently.

[0004] For example, patent CN206768174U discloses a copper coil annealing convection tray, which includes a hollow tube frame. The hollow tube frame has several sets of hollow tubes symmetrically arranged along the circumference. One end of each set of hollow tubes passes through the through hole on the tube body of the hollow tube frame to form convection. Between two adjacent hollow tubes, an outer ring rib tube column and an inner ring rib tube column are arranged sequentially from the outside to the inside. Each hollow tube used to support the copper coil has a different orientation. After annealing, the operation of removing the copper coil is cumbersome. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a copper coil vacuum annealing rack, which simplifies the copper coil removal process.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] The copper coil vacuum annealing rack includes an annealing rack base and a fixed column located at the center of the annealing rack base. The fixed column is equipped with a set of copper coil support rods for suspending the copper coil. The copper coil support rods are hollow tubes, and the tube wall is provided with an opening groove along the axial direction of the hollow tube.

[0008] Further or preferred:

[0009] The hollow tube is a hollow circular tube.

[0010] The opening groove is located at the top of the hollow circular tube.

[0011] The outer end of the opening groove extends to the outer end of the hollow circular tube.

[0012] The opening slot is a U-shaped slot.

[0013] The outer end of the copper coil support rod is provided with a detachable baffle.

[0014] The hollow tube has an internal thread at its outer port, and a connecting cylinder is located at the center of the baffle. The connecting cylinder is connected to the threaded structure at the outer port.

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] The copper coil vacuum annealing rack has a reasonable structural design. A set of copper coil support rods facing different directions are all hollow round tubes. The tube wall has an opening groove along the tube axis. After annealing, the L-shaped pull rod is inserted into the hollow round tube. The inner end of the pull rod is located in the opening groove, which can pull out the copper coil. The copper coil removal operation is simple and effectively improves production efficiency.

[0022] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and through the description of the examples.

[0023] like Figure 1 and Figure 2 As shown, the copper coil vacuum annealing rack includes an annealing rack base 1 and a fixed column 4 located at the center of the annealing rack base. The fixed column is provided with a set of copper coil support rods 5 for suspending the copper coil. The copper coil support rods are hollow tubes, and the tube wall is provided with an opening groove 501 along the axial direction of the hollow tube.

[0024] This utility model has a reasonable design for a copper coil vacuum annealing rack. A set of copper coil support rods facing different directions are all hollow round tubes. The tube wall of the hollow round tube has an opening groove along the tube axis. After annealing, the L-shaped pull rod is inserted into the hollow round tube. The inner end of the pull rod is located in the opening groove, which can pull out the copper coil. The copper coil removal operation is simple and effectively improves production efficiency.

[0025] The annealing rack base 1 includes a frame structure base with a disc on it. The disc has a set of through holes to facilitate airflow circulation. The frame structure base is stable and reliable.

[0026] A set of positioning holes 2 is provided on the outer edge of the annealing rack chassis, and a support column 3 is installed corresponding to the positioning holes. The lower end of the support column is detachably inserted into the positioning hole. The annealing rack can be stacked by supporting a set of support columns and a fixed column located in the middle position.

[0027] The hollow tube is a hollow circular tube, with an opening groove located at the top of the hollow circular tube; the outer end of the opening groove extends to the outer end of the hollow circular tube. Furthermore, the opening groove 501 is a U-shaped groove.

[0028] The copper coil is hung on a hollow tube with its center hole. The hollow tube is set horizontally, and a set of hollow tubes is spatially staggered to position multiple copper coils. After annealing, the copper coil is removed from the hollow tube. A pull rod is inserted into the hollow tube, and the inner end of the pull rod is bent out from the opening slot and contacts the inside of the copper coil. With the help of hoisting, the copper coil is removed from the hollow tube by the pull rod. The removal operation is simple and effectively improves production efficiency.

[0029] Furthermore, the outer end of the copper coil support rod is equipped with a detachable baffle to prevent the copper coil from slipping when it is hoisted into the annealing furnace.

[0030] The hollow tube has an internal thread at its outer end, and a connecting cylinder is located at the center of the baffle. The connecting cylinder has an external thread that mates with the internal thread, and the connecting cylinder is connected to the threaded structure at the outer end. The threaded structure on the hollow tube is an internal thread and will not affect the copper coil removal operation.
