Description

Technical Field

[0001] This utility model belongs to the field of cutting device technology, and in particular relates to a metal cutting tool with anti-wear function. Background Technology

[0002] Metal cutting accounts for a large proportion of modern mechanical manufacturing. Its main function is to remove metal from the workpiece using cutting tools. However, wear is inevitable during the machining process. To reduce the wear of cutting tools, cutting fluid is usually added during cutting for lubrication and cooling.

[0003] Currently, cutting fluid is usually sprayed onto the cutting blade by setting a nozzle on the side of the blade. However, the blade rotates at a high speed during cutting, so the cutting fluid is thrown out the moment it touches the blade, resulting in too short a contact time between the cutting fluid and the blade. In addition, since the blade tip width is smaller than the blade body, the cutting fluid cannot reach the blade tip when it is thrown out, resulting in uneven cooling of various parts of the blade and easy deformation. Utility Model Content

[0004] This invention provides a metal cutting tool with anti-wear function, aiming to solve the problems of poor cooling effect of current cutting tools and large wear caused by uneven cooling.

[0005] This utility model is implemented as follows: a metal cutting tool with wear resistance includes a bracket; a motor is mounted on the lower side of the bracket, the output shaft of the motor is connected to a rotating shaft, the other end of the rotating shaft is connected to a blade, a protective cover is mounted on the right side of the bracket, a water tank is mounted on the top of the bracket, a water pump is installed inside the water tank, an upper nozzle is mounted on the top of the protective cover and a side nozzle is mounted on the right side, the water pump outlet in the water tank is connected to an infusion pipe, the infusion pipe is a T-connector and its other two ends are connected to the upper nozzle and the side nozzle respectively, and the blade has embedded grooves on both sides of its surface.

[0006] Preferably, the bottom of the upper nozzle has several horizontally opened spray holes, and the spray holes on both sides of the upper nozzle are inclined inward.

[0007] Preferably, the side wall of the side nozzle has a plurality of spray holes, and all spray holes are outwardly expanding.

[0008] Preferably, the surface of the water tank is welded with heat sinks, and the heat sinks are arranged in several groups and are evenly distributed. A fan is installed on the side of the water tank, and the air outlet of the fan faces the gap of the heat sinks.

[0009] Preferably, the surface of the rotating shaft is threaded, the center of the blade is provided with a threaded groove that matches the thread on the surface of the rotating shaft, a sliding groove is provided on the side of the rotating shaft near the blade, and a limiting plate is slidably installed in the sliding groove, a spring is installed in the sliding groove of the rotating shaft, the movable end of the spring is connected to the limiting plate, a limiting groove that matches the limiting plate is provided on the side wall of the blade, the limiting plate is slidably installed on the rotating shaft by two sets of limiting blocks, and two sets of pull rings are symmetrically installed on the left side of the limiting plate.

[0010] Preferably, the surface of the blade is uniformly provided with circular slots.

[0011] Compared with the prior art, the embodiments of this application have the following main advantages:

[0012] By setting up upper and side nozzles to spray the blade tip and body separately, the blade can be cooled evenly, preventing large temperature differences that could lead to deformation and wear. Embedded grooves on both sides of the blade limit the sprayed coolant, preventing it from being thrown out upon contact with the high-speed rotating blade. This increases the contact time between the coolant and the blade, improving heat exchange and thus enhancing the cooling effect. A limiting plate further restricts the blade's rotation, preventing relative rotation between the blade and the shaft, ensuring a secure connection and preventing thread wear or loosening due to speed differences.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This utility model embodiment provides a metal cutting tool with wear resistance, such as Figure 1-4 As shown, the device includes a bracket 1, a motor 2 mounted on the lower side of the bracket 1, a rotating shaft 3 connected to the output shaft of the motor 2, and a blade 4 connected to the other end of the rotating shaft 3. A protective cover 5 is mounted on the right side of the bracket 1, and a water tank 6 is mounted on the top of the bracket 1. A water pump is installed inside the water tank 6. An upper nozzle 7 is mounted on the top of the protective cover 5, and a side nozzle 8 is mounted on the right side. The water pump outlet in the water tank 6 is connected to an infusion pipe 9, which is a three-way pipe with its other two ends connected to the upper nozzle 7 and the side nozzle 8, respectively. Embedded grooves 10 are formed on both sides of the blade 4. When the device is in use, the rotating shaft 3 is driven by the motor 2. The blade 4 rotates to perform cutting. During cutting, the water pump in the water tank 6 starts to supply cutting coolant from the inlet pipe 9 to the upper nozzle 7 and the side nozzle 8. The upper nozzle 7 sprays towards the tip of the blade 4, and the side nozzle 8 sprays towards the blade body of the blade 4. This allows the blade 4 to be cooled evenly, without generating a large temperature difference that could lead to deformation and wear. By opening embedded grooves 10 on both sides of the blade 4, the sprayed coolant can be limited, preventing the coolant from being thrown out as soon as it comes into contact with the high-speed rotating blade 4. This increases the contact time between the coolant and the blade 4, improves the heat exchange effect, and thus improves the cooling effect of the blade 4.

[0021] The bottom of the upper nozzle 7 has several horizontally opened spray holes 11. Both sides of the upper nozzle 7 spray holes 11 are inclined inward. Since the blade tip section of the blade 4 is inclined, the coolant sprayed by the upper nozzle 7 will be evenly spread to the surface of the blade tip, and there will be no situation where the coolant cannot be released in a certain position, resulting in uneven cooling.

[0022] The side wall of the side nozzle 8 is provided with several spray holes 11, and all spray holes 11 are outwardly expanding. By setting the side nozzle 8 to outwardly expanding, the sprayed coolant can be evenly diffused to the blade of the blade 4, thereby improving the cooling effect of the blade of the blade 4.

[0023] The surface of the water tank 6 is welded with heat sink 12. Several groups of heat sink 12 are arranged and evenly distributed. A fan 13 is installed on the side of the water tank 6. The air outlet of the fan 13 faces the gap of the heat sink 12. With the heat sink 12 and fan 13, since the coolant is usually circulated, the temperature will rise after long-term use. Here, the heat sink 12 is installed on the surface of the water tank 6 to conduct heat away, and the airflow speed near the heat sink 12 is increased by the fan 13 to make the coolant cool down quickly after heat exchange, thereby ensuring the effective cooling of the blade 4.

[0024] The rotating shaft 3 has threads on its surface, and the blade 4 has a threaded groove at its center that matches the threads on the rotating shaft 3. The rotating shaft 3 has a sliding groove on the side near the blade 4, and a limiting plate 14 is slidably installed in the sliding groove. A spring 15 is installed in the sliding groove of the rotating shaft 3, and the movable end of the spring 15 is connected to the limiting plate 14. The side wall of the blade 4 has a limiting groove that matches the limiting plate 14. The limiting plate 14 is slidably installed on the rotating shaft 3 by two sets of limiting blocks 16. Two sets of pull rings 17 are symmetrically installed on the left side of the limiting plate 14. By setting the limiting plate 14, when the rotating shaft 3 is installed, the pull rings 17 can be pulled to move the limiting plate 14 away from the blade 4. After installation, the pull rings 17 are released, and the limiting plate 14 is locked into the limiting groove of the blade 4 under the elastic force of the spring 15, so that the blade 4 and the rotating shaft 3 cannot rotate relative to each other, ensuring a tight connection and preventing thread crushing, wear, loosening, or falling off due to speed difference.

[0025] The surface of the blade 4 is uniformly provided with circular slots. By opening circular slots on the surface of the blade 4, its weight can be reduced and the contact surface with air can be increased, thereby improving the heat dissipation effect.
