Description

Technical Field

[0002] Annealing is a metal heat treatment process, which means slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate speed. The purpose is to reduce hardness, improve machinability; reduce residual stress, stabilize size, reduce deformation and crack tendency; refine grains, adjust structure, and eliminate structural defects.

[0003] When the existing annealing equipment anneals the tin-plated phosphor bronze wire, the tin-plated phosphor bronze wire is directly sent into the annealing equipment, which will absorb the heat inside the annealing equipment, causing the temperature inside the equipment to drop. Raising the temperature inside the equipment again requires additional energy consumption. Moreover, when the tin-plated phosphor bronze wire is directly sent into the annealing equipment, when it is heated and annealed, it may cause uneven temperature distribution inside and outside the tin-plated phosphor bronze wire, resulting in local stress concentration, which affects the annealing effect.

[0004] Therefore, it is necessary to improve the annealing equipment in the prior art. Utility Model Content

[0021] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0022] “Top surface”, “bottom surface” and “underside” are based on the normal use state of the annealing equipment and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as a limitation on the present invention.

[0023] like Figure 1-4 As shown, a tin-plated phosphor bronze wire annealing device includes a heating chamber 1 with a heater 7 arranged inside, the heating chamber 1 is connected to a preheating chamber 4 and a cooling chamber 2, the preheating chamber 4, the heating chamber 1 and the cooling chamber 2 are connected end to end in sequence to form a channel for a wire body 6 of the tin-plated phosphor bronze wire to pass through, the cooling chamber 2 is provided with an air intake pump 5, and the cooling chamber 2 is connected to the preheating chamber 4 through a pipeline 3.

[0024] The above-mentioned annealing equipment is not only suitable for the annealing treatment of the wire body 6, but also can be applied to the annealing treatment of other wire materials; when in use, the guide wheel 8 arranged inside the preheating chamber 4, the heating chamber 1 and the cooling chamber 2 changes the forward direction of the wire body 6, so that the wire body 6 passes through the preheating chamber 4, the heating chamber 1 and the cooling chamber 2 in turn, and the heater 7 arranged inside the heating chamber 1 heats and anneals the wire body 6. After the annealing treatment is completed, the wire body 6 in a high-temperature state enters the cooling chamber 2, and the air intake pump 5 sends external air into the cooling chamber 2, and the air flow takes away the heat on the wire body 6 to achieve cooling of the wire body 6. At the same time, after the airflow after absorbing heat and heating enters the preheating chamber 4 through the pipeline 3, the airflow exchanges heat with the wire body 6 inside the preheating chamber 4, thereby transferring heat to the wire body 6, to achieve preheating of the wire body 6 inside the preheating chamber 4, and finally the airflow that completes the heat exchange is discharged to the outside of the preheating chamber 4.

[0025] In the above-mentioned annealing equipment, the residual heat on the wire body 6 after the annealing treatment can be used to preheat the wire body 6 before the annealing treatment, so as to increase the temperature of the wire body 6 entering the heating chamber 1, thereby reducing the energy consumption of the heater 7 to heat the wire body 6, and improving the energy-saving effect of the annealing equipment; and by increasing the internal temperature of the wire body 6 after preheating, the temperature difference between the inside and outside of the wire body 6 when the heater 7 heats the wire body 6 can be reduced, so that the stress distribution of the wire body 6 is uniform, and the effect of the annealing treatment of the wire body 6 by the annealing equipment is improved, so as to improve the quality of the wire body 6.

[0026] A further improvement is, Figure 1 and 2As shown, the preheating chamber 4, the heating chamber 1 and the cooling chamber 2 are all tubular structures, and are parallel to each other. The preheating chamber 4 and the cooling chamber 2 are both located on the side of the heating chamber 1, so that the preheating chamber 4, the heating chamber 1 and the cooling chamber 2 are connected to form an S-shaped distribution structure. The preheating chamber 4, the heating chamber 1 and the cooling chamber 2 are arranged in parallel in an S-shaped distribution. Compared with the preheating chamber 4, the heating chamber 1 and the cooling chamber 2 being arranged in sequence along a straight line, the overall length of the preheating chamber 4, the heating chamber 1 and the cooling chamber 2 after the connection can be greatly shortened without reducing the length of the preheating chamber 4, the heating chamber 1 and the cooling chamber 2, thereby reducing the overall volume of the annealing equipment and making the equipment more flexible and convenient to use.

[0027] A further improvement is, Figure 1 As shown, a plurality of pipes 3 are provided, and each pipe 3 is arranged at equal intervals along the extension direction of the heating chamber 1. By providing a plurality of pipes 3, the speed of delivering the waste heat inside the cooling chamber 2 to the inside of the preheating chamber 4 can be increased, and the uniformity of the hot air flow after entering the inside of the preheating chamber 4 can be increased, thereby improving the preheating effect of the wire body 6 inside the preheating chamber 4.

[0028] A further improvement is that the front end of the heating chamber 1 is connected to the end of the preheating chamber 4, the end of the heating chamber 1 is connected to the front end of the cooling chamber 2, the air intake pump 5 is arranged on the front end of the cooling chamber 2, and the inner diameter of each pipe 3 decreases successively along the front end to the end of the heating chamber 1. In the above-mentioned annealing equipment, the inner diameter of the pipeline 3 near the air intake pump 5 is small and the ventilation volume is small, while the inner diameter of the pipeline 3 far away from the air intake pump 5 is large and the ventilation volume is large. In this way, while ensuring the ventilation volume and ventilation uniformity between the cooling chamber 2 and the preheating chamber 4, after the external air flow enters the cooling chamber 2, no large amount of air flow will directly enter the preheating chamber 4 through the pipeline 3, but can better flow to the end of the cooling chamber 2 far away from the air intake pump 5, so that the air flow can fully contact the wire body 6 inside the cooling chamber 2, and the end of the preheating chamber 4 connected to the pipeline 3 with a small inner diameter is used to deliver the wire body 6 and also to discharge excess airflow. In this way, the pipeline 3 with a large inner diameter delivers the highest temperature airflow to the preheating chamber 4, and it needs to pass through the entire preheating chamber 4 before it can be discharged, thereby extending the preheating time of the hot air flow on the wire body 6 and improving the preheating effect.

[0029] A further improvement is, Figure 3 As shown, the preheating chamber 4 is a circular tubular structure, and the end port of the pipe 3 connected to the preheating chamber 4 is oriented in the same direction as the tangent direction of the preheating chamber 4. In the above annealing equipment, the pipe 3 can send the hot air flow into the preheating chamber 4 along the tangent direction, so that the hot air flow rotates around its axis in the preheating chamber 4, extending the flow path length of the hot air flow in the preheating chamber 4, increasing the contact time between the hot air flow and the wire body, and improving the preheating effect; and multiple rotating hot air flows can also play a role in mixing and stirring, making the temperature inside the preheating chamber 4 more uniform.

[0030] A further improvement is, Figure 4 As shown, a porous heat-insulating pad 9 is arranged inside the preheating chamber 4, and the heat-insulating pad 9 is annular and coaxially arranged with the preheating chamber 4. The heat-insulating pad 9 can be made of glass wool, and the heat loss inside the preheating chamber 4 can be reduced by the heat-insulating pad 9, and the temperature inside the preheating chamber 4 can be increased, thereby improving the preheating effect on the wire body 6; and when the hot air flow passes through the pores of the heat-insulating pad 9, the flow path of the hot air flow can be extended, and the heat exchange time between the hot air flow and the wire body can be extended, thereby further improving the preheating effect on the wire body 6.

[0031] A further improvement is, Figure 2 As shown, a plurality of heat preservation pads 9 are provided, and each heat preservation pad 9 is staggered with each pipe 3. The heat preservation pad 9 and the pipe 3 are staggered, so that the heat preservation pad 9 can avoid the air outlet range of the pipe 3, reduce the resistance of air flow in this range, and make the hot air flow form a cyclone better inside the preheating chamber 4, thereby improving the uniformity of heat distribution inside the preheating chamber 4 and improving the preheating effect of the wire body 6.

[0032] A further improvement is, Figure 1 and 2 As shown, the ports of the preheating chamber 4, the heating chamber 1 and the cooling chamber 2 are all open, and the end caps 10 are sealed at the ports. The two end caps 10 provided at the end of the cooling chamber 2 and the front end of the preheating chamber 4 are both provided with openings for the wire body 6 to pass through. The provision of the end caps 10 can facilitate the maintenance of the interior of the heating chamber 1, the preheating chamber 4 and the cooling chamber 2, and improve the convenience of equipment maintenance; plugs can also be provided at the connection between the cooling chamber 2 and the preheating chamber 4 and the heating chamber 7, while ensuring that the wire body 6 can pass smoothly, the amount of external airflow entering the interior of the heating chamber 1 can be reduced, so that the temperature inside the heating chamber 1 remains stable and the annealing effect is improved; a plurality of openings can be provided on the end cap 10 provided at the front end of the preheating chamber 4, so as to ensure that the excess air inside the preheating chamber 4 can be effectively discharged.
