Description

Technical Field

[0001] The invention belongs to the technical field of metallurgical equipment, and particularly relates to a synchronous lubrication and temperature measuring device for aluminum ingots and a working method thereof. Background Art

[0002] During the aluminum alloy extrusion process, the aluminum ingot generally needs to be lubricated and temperature measured before it is loaded and extruded. The purpose of lubrication is to prevent the extrusion pad from sticking to the aluminum ingot, so as to avoid damage to the extrusion pad or the die when the rod is withdrawn. The purpose of temperature measurement is to accurately obtain the temperature of the aluminum ingot and form extrusion process data.

[0003] Aluminum ingots are lubricated by burning natural gas at the rear of the ingot, forming a layer of carbon powder on the surface. Alternatively, lubricants such as paraffin oil are applied manually. To accurately measure the temperature of the aluminum ingot before loading, contact temperature measurement is typically used, often using a resistance thermometer (RTM) that measures the surface directly. This is labor-intensive and environmentally unfriendly.

[0004] Under existing technical conditions, lubrication and temperature measurement of aluminum ingots are generally completed in two steps before extrusion and loading, and are mostly completed manually, which is labor-intensive and environmentally unfriendly. At the same time, since the implementation of aluminum ingot lubrication and temperature measurement will take up production time, it will affect production efficiency to a certain extent. Summary of the Invention

[0005] In order to solve the above-mentioned existing problems, the purpose of the present invention is to provide an aluminum ingot synchronous lubrication and temperature measurement device and a working method thereof, which can synchronously complete the lubrication and temperature measurement of extruded aluminum ingots, improve production efficiency, and save manpower and material resources.

[0006] The present invention is achieved through the following technical solutions:

[0007] The invention discloses a synchronous lubrication and temperature measuring device for aluminum ingots, comprising a temperature measuring thermocouple, a spring, a lubrication cover, a guide tube, a position detection device, a lubrication spray gun, a movable frame, a reduction motor, a linear guide rail and a fixed frame;

[0008] The movable frame is installed on the fixed frame through a linear guide rail, and the lubrication cover and the reduction motor are installed on the movable frame; the guide tube passes through the lubrication cover and is fixedly connected to the lubrication cover; the position detection device is fixed at the rear end of the lubrication cover; the temperature measuring thermocouple is sleeved in the guide tube, and the front part of the temperature measuring thermocouple is provided with a limit step, and the rear part is provided with a positioning step, and the positioning step is located within the detection range of the position detection device; the spring is sleeved on the temperature measuring thermocouple, and the two ends are respectively abutted against the limit step of the temperature measuring thermocouple and the front end face of the guide tube; the lubrication spray gun is fixed in the lubrication cover.

[0009] Preferably, a drag chain assembly is connected between the movable frame and the fixed frame; the rear end of the temperature measuring thermocouple is connected to the thermocouple connecting wire, and the rear end of the lubricating spray gun is connected to the lubricating spray gun connecting pipeline; the thermocouple connecting wire, the lubricating spray gun connecting pipeline, the connecting wire of the reduction motor and the connecting wire of the position detection device pass through the drag chain assembly and are connected to the external equipment.

[0010] Preferably, the position detection device includes a forward position proximity switch and a backward position proximity switch arranged parallel to the axis of the temperature measuring thermocouple, and the positioning step of the temperature measuring thermocouple moves between the forward position proximity switch and the backward position proximity switch.

[0011] Preferably, the lubrication lance is fixed in the center of the lubrication hood.

[0012] Preferably, the diameter of the lubrication cover is larger than the diameter of the aluminum ingot.

[0013] Preferably, the temperature measuring tip of the temperature measuring thermocouple extends out of the lubrication cover, and the nozzle of the lubrication spray gun is located in the lubrication cover.

[0014] Preferably, a limit block is provided between the temperature measuring thermocouple and the guide tube.

[0015] Preferably, the fixing frame is connected to a tray, and the tray is located directly below the opening of the lubrication cover.

[0016] Further preferably, the lubrication cover is trumpet-shaped.

[0017] The working method of the aluminum ingot synchronous lubrication and temperature measuring device disclosed in the present invention includes:

[0018] The motor reducer drives the movable frame to move forward along the linear guide rail, driving the temperature measuring thermocouple to move forward together. The temperature measuring tip at the front end of the temperature measuring thermocouple contacts the end face of the aluminum ingot and retreats to squeeze the spring under the force of the end face of the aluminum ingot. The spring is compressed until the positioning step of the temperature measuring thermocouple triggers the position detection device to stop the motor reducer; the lubricating spray gun starts to spray lubricant to lubricate the end face of the aluminum ingot. During this process, the temperature measuring thermocouple measures the temperature of the aluminum ingot; after the lubricating spray gun finishes spraying, the motor reducer drives the movable frame to retreat, and the temperature measuring thermocouple resets under the restoring force of the spring until the positioning step of the temperature measuring thermocouple triggers the position detection device to stop the motor reducer, and the movable frame returns to its initial position.

[0019] Compared with the prior art, the present invention has the following beneficial technical effects:

[0020] The present invention discloses a synchronous lubrication and temperature measurement device for aluminum ingots. The device integrates a temperature-measuring thermocouple and a lubrication spray gun. By moving a mobile frame along a linear guide rail, the thermocouple not only measures temperature during lubrication and temperature measurement, but also provides signals for the spraying of the lubrication spray gun and the start and stop of the reduction motor through its own positioning step in conjunction with a position detection device. It also provides signals for the forward and backward movement of the entire mobile frame, ensuring the reliability of the synchronous lubrication and temperature measurement. After lubrication and temperature measurement, a spring can return to its original position and drive the thermocouple to reset, thus achieving automated operation of the synchronous lubrication and temperature measurement, improving production efficiency and saving manpower and material resources.

[0021] Furthermore, the thermocouple connecting wires, the lubrication spray gun connecting pipelines, the connecting wires of the reduction motor and the connecting wires of the position detection device are flexibly connected through the drag chain assembly to avoid damage; and the wiring is neat.

[0022] Furthermore, the lubrication spray gun is fixed at the center of the lubrication cover, which facilitates accurate positioning of the lubrication spray gun.

[0023] Furthermore, the diameter of the lubricating cover is larger than the diameter of the aluminum ingot, so that the lubricant sprayed by the lubricating spray gun can be evenly attached to the surface of the aluminum ingot, and the spraying range does not exceed the outer circle of the lubricating cover, which can ensure the lubrication effect without causing waste of lubricant.

[0024] Furthermore, a limit block is provided between the temperature measuring thermocouple and the guide tube to prevent the temperature measuring thermocouple from being displaced too long, causing the spring to be compressed and deformed too much and difficult to recover.

[0025] Furthermore, the fixing frame is connected to a tray, which is located directly below the opening of the lubrication cover and can receive excess lubricant.

[0026] Furthermore, the lubrication cover is trumpet-shaped with a large opening, which facilitates lubrication and temperature measurement at the front end.

[0027] The working method of the aluminum ingot synchronous lubrication and temperature measurement device disclosed in the present invention has a high degree of automation, can synchronously complete the lubrication and temperature measurement of the extruded aluminum ingot, improves production efficiency, and saves manpower and material resources.

DETAILED DESCRIPTION

[0031] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments, which are intended to explain the present invention rather than to limit it:

[0032] like Figure 1 The present invention provides a synchronous lubrication and temperature measuring device for aluminum ingots, comprising a temperature measuring thermocouple 2, a spring 3, a lubrication cover 4, a guide tube 5, a position detection device 6, a thermocouple connecting wire 7, a lubrication spray gun connecting pipeline 8, a lubrication spray gun 9, a movable frame 10, a reduction motor 11, a drag chain assembly 12, a linear guide rail 13 and a fixed frame 14.

[0033] like Figure 2 , wherein the lubricating cover 4 is installed on the movable frame 10, the upper half of the lubricating cover 4 is welded with a guide tube 5, and the rear end is welded with a position detection device 6. The front and rear ends of the temperature measuring thermocouple 2 are both provided with steps, and the rear end is connected to a thermocouple connecting wire 7, and the temperature measuring tip of the front end is directly opposite to the upper end face of the aluminum ingot 1. The temperature measuring thermocouple 2 is installed on the lubricating cover 4, passing through the guide tube 5 and the spring 3, and the spring 3 is located between the step surface of the front section of the temperature measuring thermocouple 2 and the end face of the guide tube 5. Two proximity switches for the forward position and the reverse position are installed on the position detection device 6. The step at the rear end of the thermocouple 2 is directly opposite to the forward position proximity switch or the reverse position proximity switch of the position detection device 6, and the position state of the temperature measuring thermocouple 2 can be detected through the step at the rear end.

[0034] The lubricating spray gun 9 is fixed at the center of the lubricating cover 4, with the front end outlet of the lubricating spray gun 9 facing the center of the end face of the aluminum ingot 1, and the rear end is connected to the lubricating spray gun connecting pipeline 8.

[0035] The diameter of the lubricating cover 4 is slightly larger than the diameter of the aluminum ingot 1 .

[0036] The front end of the temperature measuring thermocouple 2 is closer to the end face of the aluminum ingot 1 than the front end outlet of the lubricating spray gun 9, wherein the temperature measuring tip of the front end of the temperature measuring thermocouple 2 is close to the end face of the aluminum ingot 1 and exposed outside the lubricating cover 4; the front end outlet of the lubricating spray gun 9 is inside the lubricating cover 4, leaving a certain distance from the end face of the aluminum ingot 1.

[0037] A reduction motor 11 is mounted on the mobile frame 10, driving the frame 11 and all its mounted components forward and backward. A linear guide 13 is installed between the fixed frame 14 and the mobile frame 10, ensuring the frame 10 can move forward and backward freely. A drag chain assembly 12 is installed between the fixed frame 14 and the mobile frame 10, providing a flexible connection between the thermocouple connecting wires 7 and the lubrication spray gun connecting pipeline 8 on the mobile frame 10.

[0038] The aluminum ingot 1 is independent of other components, is concentric with the lubricating cover 4 , and has an end face close to the temperature measuring tip of the front end of the temperature measuring thermocouple 2 .

[0039] When lubrication and temperature measurement are performed, the reduction motor 11 drives the entire movable frame 10 forward, and the temperature measuring thermocouple 2 moves forward together under the drive of the reduction motor 11. At this time, the temperature measuring tip at the front end of the temperature measuring thermocouple 2 contacts the end face of the aluminum ingot 1. Since the aluminum ingot 1 always remains stationary, the aluminum ingot 1 retreats against the temperature measuring thermocouple 2, and the spring 3 is compressed at the same time until the temperature measuring thermocouple 2 retreats to the tail end step of the temperature measuring thermocouple 2, causing the retreat switch of the position detection device 6 to send a signal, and the reduction motor 11 stops moving forward. At this time, the lubrication spray gun 9 starts to spray lubricating liquid (powder) to lubricate the end face of the aluminum ingot 1. During this process, since the thermocouple 2 always remains in contact with the aluminum ingot 1, the temperature of the aluminum ingot 1 can be accurately measured. After the lubrication spray gun 9 finishes spraying, the reduction motor 11 drives the entire movable frame 10 to retreat. At this time, the temperature measuring thermocouple 2 keeps moving forward due to the restoring force of the spring 3 until the tail end step of the temperature measuring thermocouple 2 causes the forward switch of the position detection device 6 to send a signal. The reduction motor 11 stops retreating, the movable frame 10 returns to its initial position, the spring 3 resets, and the temperature measuring thermocouple 2 also returns to its initial position, waiting for the next aluminum ingot 1 to perform synchronous lubrication and temperature measurement.

[0040] Since the diameter of the lubricating cover 4 is slightly larger than the diameter of the aluminum ingot 1, the lubricating liquid (powder) sprayed by the lubricating spray gun 9 can be evenly attached to the surface of the aluminum ingot 1, and the spraying range does not exceed the outer circle of the lubricating cover 4, which can ensure the lubrication effect without causing waste of lubricating liquid (powder).

[0041] The temperature measuring thermocouple 2 is used for temperature measurement. At the same time, it provides a signal for the lubrication spray gun 9 to spray through its own step and the position detection device 6. It also provides a stop signal for the entire movable frame 10 to move forward and backward, and provides a signal for the end of the lubrication temperature measurement process, ensuring the reliability of the synchronous lubrication temperature measurement and realizing the automatic operation of the synchronous lubrication temperature measurement.

[0042] The temperature measuring time of the temperature measuring thermocouple 2 can be extended or shortened by adjusting the speed of the reduction motor 11 or adjusting the distance of the proximity switch of the position detection device 6.

[0043] The spraying time of the lubricating spray gun 9 can be set according to the process requirements.

[0044] During the entire lubrication spraying process, the drag chain assembly 12 realizes flexible connection for the thermocouple connecting wire 7 on the mobile frame 10, the lubrication spray gun connecting pipeline 8, the power supply of the reduction motor 11 and the power supply and signal transmission of the position detection device 6.

[0045] The above description is merely an embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention, or equivalent structures or equivalent process transformations made using the contents of the present invention's description and drawings, or direct or indirect applications in other related technical fields, should all be covered by the scope of protection of the present invention.
