Abstract
Description
Technical Field
[0001] The embodiments disclosed herein relate to the field of cutting machine technology, and more specifically, to a CNC sawing machine tool with a metal circular saw blade. Background Technology
[0002] In the process of modern industrialization, abrasive wheel cutting machines are widely used as a key processing equipment in many fields. In construction, from the construction of reinforced concrete structures for high-rise buildings to the installation and laying of water, electricity and heating pipes, the precise cutting of various steel bars and pipes is inseparable from the assistance of abrasive wheel cutting machines. Their excellent cutting ability can quickly cut raw materials into lengths that meet construction requirements.
[0003] However, most of the current abrasive wheel cutting machines are manually controlled. The operator pushes the blank to the appropriate position and then controls the abrasive wheel to swing downward to complete the cutting operation. However, it is ultimately difficult to meet the needs of large-scale and high-efficiency production, and it poses a great threat to the personal safety of the operators. A slight carelessness may cause accidental injuries such as cuts and punctures. Utility Model Content

[0006] Matrix;
[0007] A cutting table, which is horizontally movable and mounted on the substrate;
[0008] A cutting saw blade, which is rotatably mounted on the cutting table;
[0009] A material platform is horizontally movable on the base and located on one side of the cutting saw blade to fix the material. The moving direction of the material platform is intersected with the moving direction of the cutting table.
[0010] The cutting table is used to move the cutting saw blade to determine the cutting position, and the material table is configured to move the material after it moves so that the cutting saw blade can cut the material.
[0011] For example, in a CNC sawing machine tool for metal circular saw blades provided in at least one embodiment of this disclosure, the moving direction of the material table is perpendicular to the moving direction of the cutting table, a fixed seat is detachably provided on the material table, the fixed seat has a fixed channel for the material to pass through, a locking member is connected through the fixed seat for locking the material in the fixed channel, and one end of the locking member extends into the fixed channel.
[0012] For example, in a CNC sawing machine tool for metal circular saw blades provided in at least one embodiment of this disclosure, a fixed seat is detachably provided at one end of the material table near the cutting saw blade, and a positioning seat is slidably connected at one end of the material table away from the cutting saw blade along a direction parallel to the length of the material, the positioning seat being used to position the end of the material.
[0013] For example, in a CNC sawing machine tool for metal circular saw blades provided in at least one embodiment of this disclosure, the material table has a strip groove, and the positioning seat is slidably disposed in the strip groove.
[0014] For example, in a CNC sawing machine tool for metal circular saw blades provided in at least one embodiment of this disclosure, a support seat is slidably connected to the cutting table along the direction of movement of the material table, the support seat is used to support the cutting saw blade, and the cutting saw blade is rotatably mounted on the cutting saw blade.
[0015] For example, in at least one embodiment of this disclosure, a CNC metal circular saw blade sawing machine tool further includes:
[0016] A water pipe, which is mounted on the cutting table;
[0017] A nozzle is disposed at the water pipe opening and faces the cutting saw blade.
[0018] For example, in a CNC sawing machine tool for metal circular saw blade provided in at least one embodiment of this disclosure, the nozzle is located on the outer periphery of the cutting saw blade, the nozzle has an inclined spray surface, the inclined spray surface has a nozzle, the nozzle faces the cutting saw blade, and the width of the inclined spray surface is greater than the width of the cutting saw blade.
[0019] For example, in a CNC sawing machine tool for metal circular saw blades provided in at least one embodiment of this disclosure, there are two pipe openings and two nozzles, the nozzles and the pipe openings correspond one-to-one, and the two nozzles are arranged symmetrically up and down.
[0020] For example, in at least one embodiment of this disclosure, a CNC metal circular saw blade sawing machine tool further includes:
[0021] A receiving box is disposed on the base body, located below the cutting saw blade, and is used to receive the material and the coolant of the nozzle.

[0039] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

Therefore, they should not be construed as limitations on this disclosure.
[0044] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0045] like Figure 1 As shown, one embodiment of this disclosure illustrates a CNC sawing machine tool for metal circular saw blades, which mainly consists of a base 1, a cutting table 2, a cutting saw blade 3, and a material table 4.
[0046] The base 1, as the supporting structure of the entire machine tool, is of paramount importance. It is structurally robust and can withstand various forces generated during the cutting process, while also providing the necessary power units for each component and a stable foundation for the movement of the cutting table 2 and the material table 4.
[0047] The cutting table 2 is movably mounted on the base 1 in the horizontal direction. This design allows the cutting table 2 to be flexibly adjusted to adapt to the cutting needs of different materials. The cutting saw blade 3 is mounted on the cutting table 2 via a motor pulley. The movement of the cutting table 2 can drive the cutting saw blade 3 to the designated cutting position and maintain the stability of the cutting saw blade 3 during the cutting process.
[0048] The material platform 4 is also movably mounted horizontally on the base 1, located on one side of the cutting saw blade 3. Its movement direction intersects the movement direction of the cutting table 2; it can be perpendicular or at an angle. This unique design allows the material platform 4 to accurately deliver material to the underside of the cutting saw blade 3 for cutting. The material platform 4 is equipped with a dedicated material fixing device to ensure the stability of the material during conveying and cutting. After cutting, the material platform 4 can be reset and the material can be brought close to the cutting saw blade 3 again for repeated cutting, or new material can be reloaded for cutting.
[0049] The automatic working process of this machine tool is as follows: First, the material to be cut is placed on the material table 4 and secured firmly using the fixing device on the material table 4. Simultaneously, according to the cutting requirements, the movement parameters of the cutting table 2 and the material table 4 are set in the CNC system, including the movement speed and stroke distance. Then, the cutting table 2 moves horizontally on the base 1, driving the cutting saw blade 3 to the predetermined cutting position. At the same time, the material table 4 moves horizontally; since its movement direction intersects with that of the cutting table 2, the material table 4 pulls the secured material closer to the cutting saw blade 3. When the material moves to a suitable position below the cutting saw blade 3, the cutting saw blade 3 begins to work, rotating at high speed on the cutting table 2 to cut the material. As the material table 4 continues to move, the material is gradually cut to the required length. After cutting, the material table 4 sends the cut material out of the cutting area, awaiting further processing, and then begins the next cutting cycle.
[0050] In practical applications, this machine tool has a wide range of uses. In the construction of reinforced concrete structures for high-rise buildings, it can precisely cut reinforcing bars to meet the length requirements of different building components. In the machinery manufacturing industry, it is suitable for cutting and processing blanks of various metal parts, providing raw materials that meet dimensional requirements for subsequent machining processes, thus satisfying the large-scale, high-precision production needs of the machinery manufacturing industry.
[0051] like Figures 1-2 As shown, in some examples, the moving direction of the material table 4 is perpendicular to the moving direction of the cutting table 2. A fixed seat 5 is detachably provided on the material table 4. The fixed seat 5 has a fixed channel 501 for material to pass through. A locking member 6 is connected through the fixed seat 5 to lock the material in the fixed channel 501. One end of the locking member 6 extends into the fixed channel 501.
[0052] The material table 4 moves perpendicular to the cutting table 2, enabling precise positioning and conveying of materials in two mutually perpendicular directions. This ensures the quality of the cut products and meets the requirements of most applications. A detachable mounting base 5 is installed on the material table 4, allowing users to select the appropriate base 5 for different shapes and sizes of materials. This enhances the machine's ability to process various materials, improves the equipment's versatility and flexibility, and secures the material within the fixed channel 501 using locking components 6, making operation simple and quick. When materials need to be changed, simply loosening the locking components 6 allows for rapid removal and replacement of the old material, significantly reducing material changeover time.
[0053] Specifically, the installation method of the fixing seat 5 can be bolt connection, slot connection, etc. When placing the material, first pass the material to be cut through the fixing channel 501 of the fixing seat 5 to make the material a suitable cutting position, and then use the operation method of rotation or pushing (threaded connection, etc.) to make one end of the locking member 6 extend into the fixing channel 501, contact the material and apply pressure, thereby firmly locking the material in the fixing channel 501. After cutting, reverse the operation of the locking member 6 to release it from the material, and then take the cut material out of the fixing channel 501 for subsequent processing. Alternatively, if it is necessary to continue processing the material, adjust its position in the fixing channel 501 and repeat the above locking steps. If a different type of material is to be changed, disassemble the existing fixing seat 5 and install a fixing seat 5 adapted to the new material.
[0054] Locking components 6 commonly include bolts, set screws, or quick clamps. Bolts and set screws are suitable for applications requiring high fixing accuracy. By rotating the bolt or set screw, its end is gradually pressed against the material to achieve locking.
[0055] like Figure 3 As shown, in some examples, the end of the material platform 4 near the cutting saw blade 3 is detachably provided with a fixing seat 5, and the end of the material platform 4 away from the cutting saw blade 3 is slidably connected with a positioning seat 7 along the length of the material. The positioning seat 7 is used to position the end of the material. The material platform 4 has a strip groove 401, and the positioning seat 7 is slidably disposed in the strip groove 401.
[0056] A positioning seat 7 is provided at the end of the material table 4 away from the cutting saw blade 3. It can slide along the length of the material to accurately position the end of the material. In addition, the material table 4 is further fixed by a fixing seat 5 at the end of the material table 4 near the cutting saw blade 3 to ensure that the material is always in the accurate position throughout the cutting process. This avoids inaccurate cutting dimensions due to material position deviation and meets the requirements of high-precision processing.
[0057] In addition, it can adapt to various material lengths. The sliding connection design of the positioning seat 7 allows it to be flexibly adjusted according to materials of different lengths. Whether the material is short or long, the appropriate positioning point can be found through the sliding positioning seat 7, thereby ensuring the accuracy of cutting.
[0058] Specifically, the connection between the positioning seat 7 and the material table 4 can be achieved by setting one or more linear guide rails on the upper surface of the material table 4 away from the cutting saw blade 3. The guide rails are laid along the length of the material, and a slider adapted to the guide rail is installed at the bottom of the positioning seat 7, allowing the slider to slide smoothly on the guide rail. This structure ensures the stability and straightness of the movement of the positioning seat 7, ensuring the accuracy of material positioning. Alternatively, a strip groove 401 along the length of the material can be opened on the material table 4, and the positioning seat 7 can be fixed in position within the strip groove 401 by bolts. Specifically, the positioning seat 7 can hold the end of the material against its vertical positioning surface.
[0059] The main body of the positioning seat 7 adopts a block structure. The side near the end of the material is designed as a flat surface or a curved surface with a certain curvature to adapt to the positioning requirements of the ends of materials with different shapes. For round materials, a positioning surface with an arc groove can be used; for square materials, a flat positioning surface is used.
[0060] like Figure 4 As shown, in some examples, a support seat 8 is slidably connected to the cutting table 2 along the moving direction of the material table 4. The support seat 8 is used to support the cutting saw blade 3, and the cutting saw blade 3 is rotatably mounted on the cutting saw blade 3.
[0061] With the moving direction of the material table 4 perpendicular to the moving direction of the cutting table 2, the cutting saw blade 3 is rotatably mounted on the cutting table 2 via the support base 8. The support base 8 serves to support the cutting saw blade 3, thereby enabling the cutting saw blade 3 to adjust its cutting position in a two-dimensional plane, rather than simply adjusting its position along a horizontal linear path, thus improving flexibility.
[0062] For example, when initially cutting thinner materials, and later cutting wider materials, the cutting table 2, which moves laterally perpendicular to the moving direction of the material table 4, cannot adapt to the width adjustment. Therefore, the cutting saw blade 3 can be finely adjusted vertically by the support base 8, and then the wider materials can be cut by the movement of the material table 4.
[0063] like Figure 5 As shown, in some examples, a CNC sawing machine tool for metal circular saw blades further includes: a water pipe 9 disposed on the cutting table 2; and a nozzle 10 disposed at the opening of the water pipe 9, with the nozzle 10 facing the cutting saw blade 3.
[0064] During the cutting process, the friction between the cutting saw blade 3 and the material generates a lot of heat. Excessive temperature will reduce the service life of the saw blade. Therefore, by installing a water pipe 9 and a nozzle 10, coolant can be sprayed directly onto the cutting saw blade 3 through the nozzle 10, effectively removing the heat generated by the saw blade and further flushing away the debris generated during cutting, keeping the cutting area clean.
[0065] Specifically, when the machine tool starts to perform cutting operations, the coolant supply system connected to the water pipe 9 starts to work, including components such as water tank, water pipe 9 and water pump. The coolant flows through the water pipe 9 to the nozzle 10 set at the pipe opening and sprays onto the cutting saw blade 3. As cutting proceeds, the coolant carries debris down from the cutting area and can be recycled through the receiving box 11 set at the bottom of the machine tool.
[0066] The receiving box 11 is fitted according to the actual structure, such as... Figure 9 As shown, it is located directly below the cutting saw blade 3, so it can not only receive coolant, but also receive the cut material and collect it for easy retrieval by workers.
[0067] Common nozzle types include fan-shaped nozzles, which can cover a large area and are suitable for large-area cooling and chip removal needs. The nozzle 10 is connected to the water pipe 9 via a thread or quick-connect fitting. During installation, it should be ensured that the nozzle 10 is tightly connected to the water pipe 9 to prevent coolant leakage. The spray angle and position of the nozzle 10 can be adjusted according to the position of the cutting saw blade 3 and the cutting process requirements to change the spray direction of the nozzle 10 so that it can accurately spray coolant to the key parts of the saw blade.
[0068] like Figures 6-8 As shown, in some examples, the nozzle 10 is located on the outer periphery of the cutting saw blade 3. The nozzle 10 has an inclined spray surface 1001, and the inclined spray surface 1001 has a nozzle 1002. The nozzle 1002 faces the cutting saw blade 3, and the width of the inclined spray surface 1001 is greater than the width of the cutting saw blade 3. There are two nozzles and two pipe openings. The nozzles 10 and the pipe openings correspond one-to-one, and the two nozzles 10 are symmetrically arranged vertically. A CNC sawing machine tool for metal circular saw blades also includes: a receiving box 11 is set on the base 1, located below the cutting saw blade 3, for receiving materials and coolant from the nozzles 10.
[0069] Furthermore, the nozzle 10 is positioned on the outer periphery of the cutting saw blade 3 and has an inclined spray surface 1001. Through the inclined spray surface 1001 and the limitation of its position, the sprayed coolant can cover a larger area of the cutting saw blade 3. This is because the chips and sparks generated during cutting are usually thrown outward along the radial direction of the cutting saw blade 3 during processing, thus providing a better cooling effect. The width of the inclined spray surface 1001 is greater than the width of the cutting saw blade 3, which not only cools down the blade but also covers the sparks and chips scattered around during cutting and directs them to the receiving box 11. At the same time, the two nozzles 10, which are symmetrically arranged vertically, can further enhance the above-mentioned effects, improve safety and service life, and ensure the smooth progress of the cutting process.
[0070] The arrangement of the inclined spray surface 1001 and multiple nozzles 10 as described above ensures efficient cooling and chip removal of the cutting saw blade 3, while avoiding excessive waste of coolant. Even with recycling, efficient cooling can extend the service life of the saw blade.
[0071] Specifically, if a single nozzle 10 is used, it is necessary to ensure that the nozzle 1002 of the inclined spray surface 1001 is accurately oriented towards the cutting saw blade 3. The distance between the nozzle 10 and the cutting saw blade 3 is generally between 20-50mm to ensure that the coolant can be sprayed onto the saw blade at a suitable pressure and angle. The angle of the inclined spray surface 1001 is usually set between 30° and 60°. If two symmetrical nozzles 10 are used, then, based on the above, the two nozzles 10 need to be set on the same side of the outer periphery of the cutting saw blade 3, and arranged symmetrically from top to bottom, with the inclined spray surfaces 1001 both facing the processing position.
[0072] like Figure 10 As shown, in some examples, a CNC sawing machine tool for metal circular saw blades further includes: a protective cover 12 disposed on the base 1, having a protective area 1201, and the cutting table 2 and the material table 4 both located within the protective area 1201.
[0073] The protective cover 12 is set on the base 1, and both the cutting table 2 and the material table 4 are contained within the protective area 1201, effectively blocking the dangers caused by flying debris, coolant, and accidental detachment of the cutting saw blade 3 during the cutting process.
[0074] Specifically, an integrated protective cover 12 can be used. This protective cover 12 is a complete closed structure, usually made of metal sheet or high-strength plastic. Its shape is designed according to the shape of the machine tool and the position of the cutting table 2 and the material table 4. It tightly wraps the protective area 1201. Openable doors or inspection ports are set on one or more sides of the protective cover 12 to facilitate the loading and unloading of materials, maintenance and repair of the machine tool by the operators.
[0075] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
