Description

Technical Field

[0001] The utility model relates to the technical field of annealing machines, in particular to a horizontal annealing machine for cables. Background Art

[0002] Cable annealing machine is a kind of equipment specially used for annealing of cables (such as copper wire, stainless steel wire, steel wire, etc.). Cable annealing is a necessary process after wire drawing in the cable production process. It is used to anneal the wire surface hardening caused by wire drawing, so that the physical and mechanical properties of the wire can be restored, which is convenient for the normal progress of the subsequent process and ensures the performance of the produced cable.

[0003] The traditional horizontal annealing machine is generally operated in conjunction with the preceding wire drawing machine, but due to factors such as wire material and wire diameter, the wire drawing speed has a certain deviation. When the wire diameter changes, the wire between the annealing machine and the wire drawing machine will be too loose or too tight, causing sparks or wire thinning on the annealing copper wheel, making the wire diameter unstable, thus affecting the wire annealing quality and the service life of the annealing copper wheel; the horizontal annealing machine is also operated in conjunction with the subsequent wire taking-up device. Traditionally, it is controlled by an external tension box, but this method occupies a large area, and due to the large suspension distance between the annealing machine and the tension box, the wire is prone to jitter during operation, which leads to friction between the wire and the side wall of the guide wheel, causing scratches on the wire, thus affecting the quality of the finished wire.

[0022] Next, each embodiment of the present utility model will be described in detail with reference to Figure 1 and Figure 2 Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0023] A horizontal wire annealing machine, comprising an annealing frame 1 and a wire 2 arranged on the annealing frame 1. A first incoming wire reciprocating wheel 3, a first outgoing wire reciprocating wheel 4 and a guide wheel mechanism are rotatably connected to the annealing frame 1. A rotary drive mechanism is installed on the annealing frame 1, and the rotary drive mechanism is drivingly connected to the guide wheel mechanism. When the rotary drive mechanism drives the guide wheel mechanism to move, the guide wheel mechanism pulls the wire 2 to move. The guide wheel mechanism includes a first guide wheel 12, a second guide wheel 13, a third guide wheel 14, a fourth guide wheel 15, a first adjusting wheel 16, a second adjusting wheel 17, a first cooling reciprocating wheel 18 and a second cooling reciprocating wheel 19 rotatably arranged on the annealing frame 1. The first guide wheel 12, the second guide wheel 13, the third guide wheel 14, the fourth guide wheel 15, the first cooling reciprocating wheel 18 and the second cooling reciprocating wheel 19 are all wound and matched with the wire 2.

[0024] A positive electrode is provided on the first guide wheel 12, and a negative electrode is provided on the third guide wheel 14. The positive electrode and the negative electrode are not shown. Both the positive electrode and the negative electrode are in contact with the wire 2. When the wire 2 between the positive electrode and the negative electrode is energized, the wire 2 itself is heated.

[0025] The wire 2 between the first guide wheel 12 and the third guide wheel 14 is wound and matched with any one of the first adjusting wheel 16 and the second adjusting wheel 17. Affected by factors such as the specifications and materials of the wire 2, the user can choose to wind the wire 2 with the first adjusting wheel 16 or the second adjusting wheel 17 to realize the adjustment of the length of the heating section. The increase or decrease of the length of the heating section will cause the final temperature of the wire 2 to change, improving the practicability of the device.

[0026] A first guide groove 6 and a second guide groove 7 are formed on the annealing frame 1. Sliders 8 are slidably fitted in both the first guide groove 6 and the second guide groove 7. A second incoming wire reciprocating wheel 9 and a second outgoing wire reciprocating wheel 10 are rotatably connected to the two sliders 8 respectively. The first incoming wire reciprocating wheel 3, the first outgoing wire reciprocating wheel 4, the guide wheel mechanism, the second incoming wire reciprocating wheel 9 and the second outgoing wire reciprocating wheel 10 are all wound and matched with the wire 2. When the two sliders 8 slide in the first guide groove 6 and the second guide groove 7 respectively, the positions of the second incoming wire reciprocating wheel 9 and the second outgoing wire reciprocating wheel 10 can be adjusted, so that the tension intensity of the wire 2 when incoming and outgoing changes. Two cylinders 11 are installed on the annealing frame 1, and the telescopic ends of the two cylinders 11 are fixedly connected to the two sliders 8 respectively. The cylinders 11 can drive the sliders 8 to perform linear motion.

[0027] The change in the wire diameter of cable 2 is related to the tensile strength of cable 2. If cable 2 is too loose or too tight, it will affect the finished product quality of cable 2. There are two sensors installed on the annealing rack 1. The sensors are wire diameter sensors, and the two sensors are electrically connected to the two cylinders 11 respectively. When the sensor at the incoming line detects a change in the incoming line diameter, the sensor sends a signal to the corresponding cylinder 11, and the cylinder 11 drives the second incoming line reciprocating wheel 9 to move closer to or away from the first incoming line reciprocating wheel 3, so that the tensile strength of cable 2 during the incoming process is adjusted to the set value. When the sensor at the outgoing line detects a change in the outgoing line diameter, the sensor sends a signal to the corresponding cylinder 11, and the cylinder 11 drives the second outgoing line reciprocating wheel 10 to move closer to or away from the first outgoing line reciprocating wheel 4 to adjust the tensile strength of cable 2 during the outgoing process. This device has the function of autonomously adjusting the incoming tension strength and the outgoing tension strength, avoiding that during the operation of this device, too large or too small tension strength affects the processing effect of cable 2, and even the situation of cable 2 breakage occurs.

[0028] This device also has a displacement sensor. The displacement sensor is used to measure the movement of the two sliders 8. The displacement sensor is signal-connected to the rotary drive element 24, the external wire drawing machine and the external wire take-up machine. When the sliders 8 move, that is, when the wire diameter of cable 2 changes, the operating speeds of the wire drawing machine, the external wire take-up machine and the rotary drive element 24 are automatically matched through the external control system to ensure the wire diameter stability.

[0029] A steam chamber 5 is installed on the annealing rack 1. The steam chamber 5 is connected to the external steam supply equipment. Cable 2 passes through the steam chamber 5. Through the setting of the steam chamber 5, the heating efficiency of cable 2 can be improved.

[0030] A first cooling chamber 21, a second cooling chamber 22 and a third cooling chamber 23 are installed on the annealing rack 1. The first cooling chamber 21, the second cooling chamber 22 and the third cooling chamber 23 are fluid-conducted. Any one of the first cooling chamber 21, the second cooling chamber 22 and the third cooling chamber 23 is connected to the external coolant supply equipment. The third guide wheel 14 is located inside the first cooling chamber 21. The first cooling reciprocating wheel 18 and the second cooling reciprocating wheel 19 are both located inside the third cooling chamber 23. Cable 2 passes through the first cooling chamber 21, the second cooling chamber 22 and the third cooling chamber 23 in sequence. The first outgoing line reciprocating wheel 4, the second incoming line reciprocating wheel 9 and the first cooling reciprocating wheel 18 are all double-grooved wheels.

[0031] Through the first cooling chamber 21, the second cooling chamber 22 and the third cooling chamber 23, cable 2 can be quickly cooled down. Through the cooperative setting of the first cooling reciprocating wheel 18 and the second cooling reciprocating wheel 19, the length of the cooling section of cable 2 can be increased, further improving the cooling effect. An overflow pipe 27 is provided on one side of the third cooling chamber 23. The overflow pipe 27 is used to discharge the excess coolant to keep the coolant inside at a certain liquid level.

[0032] The rotary drive mechanism includes a rotary drive element 24 installed on the annealing frame 1, the rotary drive element 24 is a servo motor, and two flat pulleys 25 are rotatably connected to the annealing frame 1. The first guide wheel 12, the third guide wheel 14 and the fourth guide wheel 15 are all provided with connecting shafts. The output end of the rotary drive element 24 is connected to the connecting shaft on the third guide wheel 14 through a first flat belt, the connecting shaft on the first guide wheel 12, the connecting shaft on the third guide wheel 14 and the flat pulley 25 are connected through a second flat belt transmission, and the connecting shaft on the first guide wheel 12 and the connecting shaft on the fourth guide wheel 15 are connected through a third flat belt transmission.

[0033] When the rotary drive element 24 is started, the third guide wheel 14 is rotated through the first flat belt, and then the first guide wheel 12, the third guide wheel 14 and the fourth guide wheel 15 are rotated synchronously by using the second flat belt, the third flat belt and the flat belt wheel 25 to realize the traction movement of the cable 2.

[0034] A wire stabilizing rack 20 and a fan 26 are installed on the annealing rack 1. The cable 2 passes through the wire stabilizing rack 20. The setting of the wire stabilizing rack 20 can improve the stability of the cable 2 during movement. The air outlet direction of the fan 26 is set toward the first guide wheel 12; when the cable 2 between the positive electrode and the negative electrode is powered on and heated, the fan 26 is used to blow air, which can prevent the positive electrode and the first guide wheel 12 from continuously working at high temperature, thereby affecting the service life.
