Description

Technical Field

[0001] This utility model relates to the technical field of track fastener cutting equipment, specifically a cutting mechanism for processing track fasteners. Background Technology

[0002] During the processing of track fasteners, the high-speed friction between the cutting disc and the metal material generates a large amount of heat, causing the temperature of the cutting disc to rise sharply. High temperature will accelerate the wear of the cutting disc material, reduce its hardness and service life. Some cutting mechanisms used for processing track fasteners are not equipped with special cooling devices, and only water flow washes the cutting disc, which cannot remove the heat generated during the cutting process in time, causing the cutting disc to be in a high-temperature state for a long time.

[0003] For example, the authorized patent document with application number CN202223258155.4 discloses a cutting mechanism for processing subway track fasteners. During cutting, a cooling nozzle sprays coolant onto the cutting blade, and then the coolant and the debris generated during cutting enter the filter chamber. In the above structure, during cutting, only water flows to wash the cutting disc and remove debris, but it cannot remove the heat generated during the cutting process in time. That is, the high temperature mentioned above will lead to a decrease in cutting accuracy and a deterioration in surface quality, which will affect the overall quality of the track fastener. Therefore, we need to provide a cutting mechanism for processing track fasteners. Utility Model Content

A cooler is installed on one side of the cutter to blow cold air to cool the cutting edge of the blade inside the cutter. The temperature-conducting plate is located inside the mounting frame, which can transfer the low temperature inside the frame into the mounting frame to assist in cooling. For precision parts such as track fasteners, excessive temperature can cause burrs and deformation on the cutting edge. Cooling with cold air can improve cutting accuracy, and rapid cooling avoids thermal stress concentration caused by local high temperature, reduces the generation of micro-cracks on the cutting edge, and extends the tool life, thus solving the problems mentioned in the background art.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a cutting mechanism for processing track fasteners, comprising:

[0025] The table 1, cutter 2, cooler 3, and clamping parts 4 are provided. The top of the table 1 is provided with clamping parts 4 for fixing the track fasteners and for fixing cylindrical and rectangular accessories. The cutter 2 is mounted on the top of the table 1 by an adjustable bracket, and the surface is provided with a cooler 3 to cool the cutting blade in the cutter 2.

[0026] The cooler 3 includes a frame 31, a cooling plate 32, a spiral air duct 33, and a fan drive 34. The frame 31 is located on one side of the cutter 2 and has a spiral air duct 33 inside. The cooling plate 32 is embedded on one side of the frame 31 and its cooling surface extends into the frame 31 and is adjacent to the spiral air duct 33. The fan drive 34 is connected to the spiral air duct 33 so that cold air is blown toward the cutting plate.

[0027] Specifically, a cooler 3 is installed on one side of the cutter 2, which can blow cold air to cool the blade edge inside the cutter 2. The heat conduction plate is located inside the mounting frame 21, which can transfer the low temperature inside the frame 31 into the mounting frame 21 to assist in cooling. For precision parts such as track fasteners, excessive temperature can cause burrs and deformation on the cutting edge. Cooling with cold air can improve cutting accuracy, and rapid cooling avoids thermal stress concentration caused by local high temperature, reduces the generation of micro-cracks on the blade edge, and extends the tool life.

[0028] The cooling surface of the cooling chip 32 is in close contact with the outer wall of the spiral air passage 33, and a thermally conductive silicone layer is filled between them. When air flows in the spiral air passage 33, the spiral structure causes the airflow to form turbulence, which extends the heat exchange path. The thermally conductive metal sheet efficiently conducts the cooling capacity of the cooling chip 32 to the airflow.

[0029] During the cutting process of track fasteners, industrial-grade cold air systems typically control the outlet temperature between -5℃ and 15℃ (depending on the tool material). For example, for carbide tools, the cold air temperature is ≥0℃ (to avoid cracking due to sudden cooling), while for high-speed steel tools, the cold air temperature can be as low as -5℃ (requires a wind speed of ≥5m / s). The outlet wind speed of the cyclone channel is generally 8-15m / s, which can effectively remove heat without generating excessive impact force.

[0030] The air drive component 34 includes a miniature fan 341, an air inlet pipe 342 and an air outlet pipe 343. The air inlet pipe 342 is located inside the frame 31 and is connected to the air inlet of the spiral air duct 33. The air outlet pipe 343 is connected to the air outlet of the spiral air duct 33.

[0031] Furthermore, when the micro fan 341 is running, external air is drawn into the spiral air passage 33 through the air inlet pipe 342. The air exchanges heat with the cooling surface of the cooling plate 32 in the spiral air passage 33 to form cold air, and then is discharged to the cutting blade through the air outlet pipe 343. The spiral air passage 33 extends the air flow path, allowing the air to fully contact the cooling surface, and the temperature of the cold air can be reduced. The directional air outlet structure ensures that the cold air is precisely applied to the cutting area.

[0032] The air outlet of the air outlet 343 faces the blade of the cutting disc, and the air inlet of the miniature fan 341 is equipped with a filter layer.

[0033] It is worth noting that the filter layer includes a combination structure of a G4 grade pre-filter and an F7 grade medium-efficiency filter. The miniature fan 341 draws in outside air, which is then filtered through two stages and delivered to the spiral air duct 33 through the air inlet pipe 342. The air in the spiral air duct 33 undergoes full heat exchange with the cooling surface of the cooling plate 32 to form cold air, which is finally blown directionally to the cutting edge of the cutting blade through the air outlet pipe 343. The two-stage filtration system controls the dust content of the incoming air to below 0.5mg / m³, preventing dust particles from entering the cooling system and extending the service life of the cooling plate 32 and the miniature fan 341.

[0034] The cutter 2 includes a mounting frame 21, a cutting disc body 22 and a driver 23. The cutting disc body 22 is rotatably mounted in the mounting frame 21, and a driver 23 for rotating the cutting disc body 22 is provided on one side. A temperature-conducting plate is embedded in one side of the mounting frame 21 and is located in the frame 31.

[0035] It should be noted that when the driver 23 drives the cutting disc body 22 to rotate and cut, the heat generated is conducted to the heat conduction plate through the mounting bracket 21. The heat conduction plate dissipates the heat into the cold air inside the frame 31. The heat conduction plate is located inside the mounting bracket 21, which can transfer the low temperature inside the frame 31 into the mounting bracket 21 to assist in cooling. For precision parts such as track fasteners, excessive temperature will cause burrs and deformation on the cutting edge. Cooling with cold air can improve cutting accuracy, and rapid cooling avoids thermal stress concentration caused by local high temperature.

[0036] The cooling chip 32 is configured as a semiconductor cooling chip 32, and the heating surface is fixedly installed with a heat dissipation fin plate 5. A positioning plate 6 for fixing the spiral air passage 33 is fixedly installed inside the frame 31.

[0037] It is worth noting that when the semiconductor cooling chip 32 is powered on, the cold side cools down the temperature inside the frame 31, and the heat from the hot side passes through the heat dissipation fins 5. The heat dissipation fins 5 raise the temperature of the hot side of the cooling chip 32, thereby improving the cooling efficiency. In conjunction with the fixing plate, thermally conductive silicone is preferably used to fill the gaps to ensure the stability of the spiral air passage 33.

[0038] The clamping component 4 includes a cylinder 41, a push plate 42, and a pressing component 43. Two cylinders 41 are fixedly installed on the top of the table 1. A push plate 42 is fixedly installed on one adjacent end of each of the two cylinders 41 for clamping rectangular parts in the track fastener. The top of the push plate 42 is provided with a pressing component 43 to clamp cylindrical parts in the track fastener.

[0039] Specifically, the track fastener to be cut is placed on the table 1. When fixing the rectangular part, the two cylinders 41 are activated to drive the two push plates 42 to move closer to each other. The two push plates 42 are provided with convex strips on adjacent sides to provide auxiliary support for the rectangular part, thereby fixing the rectangular part.

[0040] The holding member 43 includes a frame 431, a groove 432, a pressure plate 433, a V-groove 434, and an adjusting rod 435. The frame 431 is fixed to the top of the push plate 42 and has a groove 432 inside. The pressure plate 433 is slidably installed in the groove 432. The adjusting rod 435 is threadedly installed in the frame 431. The lower end of the adjusting rod 435 is rotatably installed on the top of the pressure plate 433. The pressure plate 433 and the push plate 42 are both provided with V-grooves 434 on the side that are opposite to the cylindrical accessories for clamping the cylindrical accessories in the track fastener.

[0041] Furthermore, rotating the adjusting rod 435 causes the pressure plate 433 to move down along the groove 432. The pressure plate 433 and the V-groove 434 of the push plate 42 together wrap around the cylindrical accessory, and fine-tuning and tightening are achieved through the threaded pair. The surface of the V-groove 434 is inlaid with nitrile rubber anti-slip pads.

[0042] Among them, the adjustable support of the table 1 is a three-dimensional drive frame, which realizes the three-dimensional movement adjustment of the mounting frame 21, and then controls the three-dimensional movement adjustment of the cutter 2. The adjustable support of the table 1 is a three-dimensional drive frame, including an X-axis linear module, a Y-axis linear module and a Z-axis lifting mechanism. The PLC controller controls the three-axis servo motor according to the cutting path. This adjustable support is existing technology, so it will not be described in detail.

[0043] The driver 23, cooling chip 32, cylinder 41 and adjustable bracket involved in this application are all implemented using existing mature technologies and are connected to an external PLC controller and power supply. This is a conventional technical means in this field, so their specific circuit connections, control logic and working process will not be described in detail.

[0044] In this application, the threaded surface of the adjusting rod 435 is provided with a dustproof coating and has a self-locking function, and can still be used normally when a small amount of dust is attached.

[0045] This device places the track fasteners to be cut on the table 1. When fixing rectangular parts, two cylinders 41 are activated to drive two push plates 42 closer together. Each push plate 42 has a protruding strip on an adjacent side to provide auxiliary support for the rectangular parts, thus fixing them. When fixing cylindrical parts, the cylindrical parts are positioned at the V-grooves 434 at the top of the two push plates 42, and the adjusting rod 435 is rotated to move the pressure plate 433 downwards. The V-grooves 434 at the bottom of the pressure plate 433 fit against the top of the cylindrical parts, thus fixing them. The table surface is used for this process. The adjustable bracket at the top adjusts the position of the cutter 2 and performs cutting on the fasteners. After cutting, the cooling chip 32 is powered on to cool the inside of the frame 31. The frame 31 is equipped with a temperature guide plate located inside the mounting bracket 21, which can assist in cooling the inside of the mounting bracket 21. The micro fan 341 is started to draw outside air into the spiral air passage 33 through the air inlet pipe 342. Since the spiral air passage 33 can extend the air path, the air cooling effect is better. The cold air is discharged through the air outlet pipe 343 to cool the blade surface.

[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
