Description

Technical Field

[0001] The utility model belongs to the technical field of radiator assembly, and in particular relates to a tube-fin type radiator tube threading device. Background Art

[0002] Currently, the radiators used in cooling towers on Chinese railway locomotives are primarily plate-fin radiators. Leakage failures increase with age and are difficult to repair. However, tube-fin radiators dissipate heat faster than plate-fin radiators, allowing hot fluid to cool rapidly through the pipes. In the event of a leak, the tube-fin radiator core can simply be sealed to maintain continued use, meeting current locomotive maintenance requirements for controlling radiator lifecycle costs. Tube-fin radiators have a wide range of applications, particularly those requiring high reliability, such as military, special equipment, shipbuilding, chemical, and power systems. The rail transit sector, due to its unique requirements for lightweight and miniaturization, is particularly suited. Previously, it was generally believed that tube-fin radiators could not match the power density of plate-fin radiators. However, thanks to their unique tube and fin-enhanced heat transfer technology, tube-fin radiators have overturned this perception, significantly improving heat dissipation power density compared to plate-fin radiators. This achievement, coupled with their high reliability, is poised to completely replace plate-fin radiators in the rail transit sector (price, weight, size, and reliability).

[0003] The current production process for tube-fin radiators requires threading the radiators. This involves inserting aluminum tubes into holes in the aluminum fins. Since each tube-fin radiator requires threading over 500 tubes, and a production line can assemble approximately three tube-fin radiators per day, this translates to threading nearly 1,600 tubes. This is a labor-intensive process for workers, as they must thread over 1,600 tubes per day.

[0004] Therefore, there is an urgent need for a tube-and-fin radiator ... device that can improve the tube-and-fin radiator tube-and-fin efficiency to solve the problems existing in the prior art. Utility Model Content

DETAILED DESCRIPTION

[0031] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0032] Example:

[0033] A tube-fin radiator pipe threading device, reference Figures 1-2 The apparatus comprises a work platform 1, a moving mechanism 2, and a pushing mechanism 3. The work platform 1 is used to install a tube-fin radiator 5, the moving mechanism 2, and the pushing mechanism 3. The moving mechanism 2 is located between the pushing mechanism 3 and the work platform 1 and is used to adjust the position of the pushing mechanism 3 relative to the tube-fin radiator 5 and align the aluminum tube 6 to be threaded with the end plate hole of the tube-fin radiator 5. The pushing mechanism 3 is used to place the aluminum tube 6 to be threaded and push it into the tube-fin radiator 5. The apparatus also includes an electronic control system 4, which is disposed on the work platform 1. The pushing mechanism 3 and the moving mechanism 2 are both connected to the electronic control system 4. Through this arrangement, the moving mechanism controls the height and horizontal position of the pushing mechanism to ensure that the aluminum tube to be threaded is aligned with the tube-fin radiator. The pushing mechanism then pushes the aluminum tube into the tube-fin radiator, allowing for the rapid installation of multiple aluminum tubes at once, significantly improving tube threading efficiency. Simultaneously, the electronic control system ensures that the tube threading process proceeds smoothly and quickly, avoiding errors and significantly reducing the burden on workers.

[0034] The moving mechanism 2 includes a lifting mechanism and a horizontal moving mechanism;

[0035] See also Figure 3 The lifting mechanism includes a lifting platform 2.1 and an electric cylinder 2.2. At least four sets of lifting shafts 2.3 are evenly distributed on the lower end of the lifting platform 2.1, distributed on the four corners of the lifting platform. The lifting shafts 2.3 are slidably set in the lifting holes on the working platform 1. One end of the electric cylinder 2.2 is connected to the lifting platform 2.1, and the other end is fixedly set on the working platform 1. When the electric cylinder is powered on, the lifting platform can move up and down. At the same time, the lifting shaft is confined in the linear bearing on the working platform to avoid the risk of the lifting platform tipping over. The upper end of the piston rod of the electric cylinder is connected to the lifting platform with fasteners. The cylinder body of the electric cylinder is connected to the working platform through fasteners.

[0036] See also Figure 4 The horizontal movement mechanism includes a slide rail 2.4 and a slider 2.5. The slide rail 2.4 is provided with multiple groups in parallel on the lifting platform 2.1. The slider 2.5 is slidingly provided with multiple groups on the slide rail 2.4. At least one group of the sliders 2.5 is also provided with a threaded hole and is transmission-connected to the screw rod 2.6. The screw rod 2.6 is connected to the motor 2.7. The slider 2.5 is also provided with a base 3.3 for placing the aluminum tube 6 to be pierced; the slide rails are fixed to the base by fasteners. There are three groups of slide rails, one group on each side and one group in the middle. The middle slide rail is shorter. There are seven groups of sliders in total, three groups on each left and right slide rails and one group on the middle slide rail. The slider on the middle slide rail is driven by a screw rod, and the screw rod is driven by a motor. The base is set on the slider through a fastening connector and moves with the slider.

[0037] The electric cylinder 2.2 and the motor 2.7 are both connected to the electronic control system 4.

[0038] See also Figure 5 The pushing mechanism 3 includes a pushing plate 3.1 and a linear cylinder 3.2. Two groups of linear cylinders 3.2 are arranged in parallel on the base 3.3. The two linear cylinders are installed on both sides of the base through fasteners. The pushing plate 3.1 is arranged between the two groups of linear cylinders 3.2, and the linear cylinder 3.2 drives the pushing plate 3.1 to push the aluminum tube 6 to be pierced into the tube-fin radiator 5.

[0039] A linear bearing 2.8 is further provided between the lifting shaft 2.3 and the lifting hole. The linear bearing is used to limit the movable position of the lifting shaft to prevent the lifting platform from tipping over.

[0040] The pushing mechanism 3 also includes a pressure sensor and / or a balancing valve; the linear cylinder 3.2 and the electronic control system 4 are both connected to the pressure sensor and / or balancing valve. The pushing mechanism uses pressure feedback to ensure the synchronous movement of the linear cylinders on both sides, simultaneously pushing the aluminum tube into the tube-fin radiator.

[0041] Due to the unique structure of aluminum sheets, each sheet is not necessarily stacked neatly, and each hole in the sheet is not necessarily concentric. This inevitably leads to obstructions during the tube threading process. When a tube is obstructed, the left and right linear cylinders become out of sync, thus affecting the tube threading operation. To solve this problem, it is necessary to install a balancing valve between the air pipes of the left and right linear cylinders, or to install pressure sensors in the pipelines of the left and right linear cylinders. The electronic control system can obtain the pressure signals of the two linear cylinders and control the on and off of the solenoid valves of the two linear cylinders respectively.

[0042] The tube-threading device is equipped with judgment criteria through the electronic control system, which can judge the data during the tube-threading process, thereby determining whether the aluminum tube has been completely passed through the tube-fin radiator or is stuck somewhere.

[0043] When the aluminum tube is stuck in the tube-fin radiator, the pressure of the linear cylinders on both sides of the pushing mechanism will increase. The automatic tube threading device is equipped with a pressure detection device. When the pressure exceeds a certain threshold, the electronic control system will stop the solenoid valve that controls the linear cylinder and cut off the compressed air entering the linear cylinder, thereby protecting the aluminum plate inside the tube-fin radiator from being damaged by the aluminum tube.

[0044] The linear cylinder 3.2 is also equipped with buffer blocks at both ends. The push plate 3.1 is connected to the linear cylinder 3.2 via a slider. The linear cylinder 3.2 controls the slider to move on the linear cylinder, thereby driving the push plate 3.1 to move along the linear cylinder 3.2. The slider in the middle of the linear cylinder is a permanent magnet. When compressed air enters both ends of the cylinder, the movable body in the middle of the cylinder moves within the cylinder, thereby driving the slider above to move together. In this way, when the sliders on the linear cylinders on both sides move together, they drive the push plate to move together, thereby pushing the aluminum tube into the tube-fin radiator. The slider on the cylinder and the push plate are connected by fasteners.

[0045] The bottom of the working platform 1 has two fixed wheels and two universal wheels with foot brakes, which can be pushed by the operator. The working platform can be divided into a part for carrying the tube-fin radiator and a part for carrying the aluminum tube.

[0046] The support 3.3 is also provided with a slot for fixing the aluminum tube 6 to be worn. The worker puts the aluminum tube to be worn on the pushing mechanism, which has slots with fixed intervals, and the aluminum tube automatically falls into the slots.

[0047] The operation method of this device is as follows:

[0048] First, ensure that the tube-fin radiator is placed on the work platform and the end plates of the tube-fin radiator are aligned.

[0049] Then push the automatic tube-threading device over and place it close to the position where the tube-fin radiator and the tube-fin radiator end plate are aligned (the automatic tube-threading device itself must ensure that the dimensional and positional tolerances meet the requirements).

[0050] After the automatic tube-threading device is aligned with the end plate of the tube-fin radiator, the operator operates the electrical system on the automatic tube-threading device, adjusts the up and down moving mechanism and the left and right moving mechanism, and aligns the aluminum tube to be threaded with the hole position on the end plate of the tube-fin radiator.

[0051] Finally, push to enter.

[0052] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
