AI Technical Summary

Technical Problem

The existing annealing equipment for nickel-chromium resistance heating alloy wires has a fixed cooling box structure, which cannot flexibly adjust the cooling path length and cooling intensity, resulting in over- or under-cooling, causing the alloy wire to become brittle, easily break, and have large fluctuations in resistance value.

Method used

The second cooling box is moved by a combination of a drive mechanism and a sliding component. Combined with the spray component of the second cooling mechanism, the cooling path length and cooling intensity are dynamically adapted. The position of the second cooling box is adjusted by a drive motor driving a lead screw and an adjusting seat. The number of spray nozzles is matched synchronously to form a dynamic adaptation relationship.

Benefits of technology

It achieves uniform and appropriate cooling of alloy wires of different specifications, avoids insufficient cooling, improves resistance uniformity and product consistency, saves water resources, and reduces ineffective spraying.

Abstract

The application relates to an annealing device for nickel-chromium resistance electric heating alloy wire processing, which comprises a machine base, a heating furnace is arranged on the top of the machine base, a first cooling box is connected to one end of the heating furnace, and a second cooling box is arranged in the first cooling box. The application is provided with a driving mechanism, a sliding assembly and a second cooling mechanism. The second cooling box is driven to move stably by the driving mechanism and the sliding assembly, and the cooling path length is flexibly adjusted. Meanwhile, the spray assembly in the second cooling mechanism is synchronously moved out, so that the number of second spray heads can be synchronously matched when the second cooling box moves to adjust the cooling length, thereby forming a dynamic adaptive relationship between the cooling path length and the cooling strength, different specifications of alloy wires are in a uniform and moderate cooling environment, cooling deficiency caused by the mismatch between the cooling length and the spray density is avoided, and the resistance uniformity is improved.
