Description

Technical Field

[0001] This invention belongs to the field of cutting device technology, and particularly relates to a cutting device with a built-in inclined cutting structure. Background Technology

[0002] Industrially produced metal tubes are typically continuous and long, in standard specifications, such as the common 6-meter or 12-meter lengths. However, in practical applications, whether manufacturing mechanical structures, furniture, automotive parts, or laying pipelines, it is necessary to cut long tubes into short tubes or parts of specific lengths and shapes with end-face quality that meet requirements; therefore, cutting devices for cutting metal tubes are indispensable in the industry.

[0003] Currently, most cutting devices on the market adopt a traditional layout, where the entire cutting mechanism, including the blade and drive motor, is mounted above the worktable. This structure has significant drawbacks: the motor and saw arm of each cutting device occupy a large amount of overhead operating and maintenance space, requiring sufficient safety clearances and maintenance passages between adjacent devices, making close arrangement impossible. This deficiency directly hinders the deployment of multiple cutting devices in a workshop to form a modular, assembly-line industrial integration, reducing production efficiency and space utilization, and increasing the difficulty of automation upgrades.

[0004] Therefore, there is an urgent need in this field to fundamentally improve the structural layout of existing cutting devices in order to solve the technical problems of large space occupation and unfavorable modular layout. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting device with a built-in inclined cutting structure to solve the problems of low space utilization and difficulty in modular layout caused by the external cutting mechanism in the prior art.

[0006] In view of this, the present invention provides a cutting device with a built-in inclined cutting structure, comprising: The machine frame has a worktable at the top that can position the workpiece, a clamping mechanism that can hold the workpiece, and a knife groove that runs through its upper and lower surfaces. The fixed base is mounted on the frame and located below the worktable. The fixed base is provided with an inclined guide slope. The cutting mechanism includes a tool holder, a blade, and a cutting motor. The tool holder is slidably mounted on the guide slope, the blade is rotatably mounted on the tool holder, and the cutting motor is mounted on the tool holder to drive the blade to rotate. When the tool holder is close to the worktable, the blade can pass through the cutting groove and contact the workpiece. The feed mechanism drives the cutting mechanism to move closer to or further away from the worktable along the guide ramp on the fixed base.

[0007] In the above technical solution, furthermore, two parallel guide plates are provided on the worktable, forming a guide space between the two guide plates for axial movement of the workpiece, and the cutting edge groove passes through the guide space; the clamping mechanism includes: A fixed clamp is installed on one side of a material guiding space; A horizontal clamp is movably positioned on the other side of the material guiding space; The horizontal drive component can drive the horizontal clamp to move closer to or away from the fixed clamp in the horizontal direction, so that the horizontal clamp and the fixed clamp can cooperate to clamp the workpiece in the horizontal direction. A vertical clamp is movably positioned above the material guiding space; The vertical drive component is located on the top of the guide plate. The vertical drive component can drive the vertical clamp to move closer to or away from the worktable in the vertical direction, so that the vertical clamp cooperates with the worktable to clamp the workpiece in the vertical direction.

[0008] In the above technical solution, the blade is rotatably connected to the blade holder via a rotating shaft. A driven pulley is provided at the end of the rotating shaft away from the blade, and a driving pulley is provided on the output shaft of the cutting motor. The driving pulley and the driven pulley are connected by a transmission belt.

[0009] In the above technical solution, a guide rail is further provided on the guide inclined surface, a sliding block that slides with the guide rail is provided on the bottom surface of the tool holder, a drive groove is provided in the middle of the surface of the guide inclined surface, and the tool feeding mechanism includes: The lead screw is rotatably mounted in the drive groove, and the axial direction of the lead screw is the same as the inclination direction of the guide slope. The transmission nut is located on the bottom surface of the tool holder and is connected to the lead screw drive. The feed motor is located at the bottom of the fixed base and can drive the lead screw to rotate.

[0010] In the above technical solution, a stop block is further provided at the bottom of the guide slope, and the stop block can contact the tool holder to restrict the tool holder from moving downward along the guide slope.

[0011] In the above technical solution, the guide slope is tilted at an angle of 65 degrees relative to the horizontal plane.

[0012] In the above technical solution, a dustproof plate assembly is further provided on the tool holder, and the dustproof range of the dustproof plate assembly covers the cutting motor, the driving pulley, the driven pulley, the sliding block, and the transmission nut.

[0013] In the above technical solution, a magnetic chip conveyor is further provided on the frame and below the blade, and a part of the dustproof plate group is inclinedly distributed above the magnetic chip conveyor, so that the chips can enter the magnetic chip conveyor under the guidance of the dustproof plate group.

[0014] In the above technical solution, a wire wheel is rotatably mounted on the tool holder. The wire wheel is located below the blade and contacts the blade. The wire wheel can rotate under the drive of the blade and scrape off the chips on the blade.

[0015] In the above technical solution, a protective plate assembly is further provided on the outside of the frame, and the protective range of the protective plate assembly covers the fixed base, the cutting mechanism and the feed mechanism.

[0016] The beneficial effects of this invention are: 1. Through the structural design of the frame, worktable, fixed base, cutting mechanism and feed mechanism, the cutting mechanism is built into the worktable through the inclined fixed base, which changes the traditional layout of the external cutting mechanism. This greatly reduces the space occupied above the worktable. Moreover, the entire feed and retraction trajectory of the cutting mechanism is inside the frame, which allows multiple such cutting devices to be arranged closely side by side in the workshop without the need to reserve a large maintenance passage. This is conducive to realizing the modular and intensive layout of automated production lines.

[0017] 2. The material guiding space formed by the two parallel guide plates provides precise guidance for long tube workpieces, ensuring consistent feeding position each time. The combination of horizontal and vertical clamping can apply pressure to the workpiece from two mutually perpendicular directions. Whether it is a round tube, square tube or irregular tube, it can be stably and firmly fixed, effectively preventing the workpiece from rolling, vibrating or displacing due to cutting force during the cutting process, and significantly improving the perpendicularity and dimensional accuracy of the cutting end face.

[0018] 3. The feed mechanism uses a combination of guide rails, sliding blocks, lead screws, transmission nuts, and feed motors. Through the precise transmission of the lead screw and nut pair, precise control of the blade's feed and retraction movements (such as speed, position, and acceleration) is achieved. This provides a technical foundation for automated cutting. The optimal feed speed can be flexibly set according to the material and wall thickness of different pipes, thereby maximizing cutting efficiency while ensuring cutting quality.

[0019] 4. The stop block provides a reliable mechanical hard limit. In case of abnormalities such as control system failure, program error or servo motor overshoot, the stop block can physically prevent the tool holder from continuing to slide down, preventing the blade from violently colliding with the frame and avoiding serious equipment damage and possible personal injury.

[0020] 5. The 65-degree design of the guide ramp on the fixed base allows the cutting mechanism to obtain sufficient gravity to assist the downward movement (which is beneficial for rapid blade retraction) without excessively increasing the load on the feed mechanism. At the same time, at this angle, the circular blade has an ideal entry angle when it passes through the blade groove and contacts the circular tube, resulting in less cutting resistance and fewer burrs. In addition, this angle provides relatively ample space for the chip removal system (such as a magnetic chip conveyor) under the worktable and for maintenance operations.

[0021] 6. By installing a magnetic chip conveyor and tilting a portion of the dustproof plate assembly above it, automated and centralized chip collection is achieved. The dustproof plate assembly not only serves as a protective cover but also acts as a guide funnel for the chips, using gravity to guide them to the magnetic chip conveyor. The magnetic chip conveyor is specifically designed for ferromagnetic chips and can efficiently separate and automatically discharge the chips from the coolant, eliminating the heavy labor of frequent manual cleaning, maintaining a clean workshop environment, and facilitating the recycling of coolant.

[0022] 7. By setting up a wire wheel that contacts the blade and can be driven by the blade, a completely passive, self-cleaning device for the blade is provided to the cutting device without additional power. When cutting soft metals (such as aluminum and copper) or coated pipes, the blade is prone to "tooth jamming" (chips sticking to the tooth grooves), which leads to reduced cutting efficiency and severe heat generation. The wire wheel uses the rotational power of the blade itself to scrape off these adhering substances in real time, keeping the blade sharp at all times. This structure is simple, reliable, and extremely low in cost, but has significant effects, effectively extending blade life and improving the quality of the cutting surface.

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0038] Example 1

[0039] like Figures 1-11 As shown, this embodiment of the invention provides a cutting device with a built-in inclined cutting structure, including: a frame 1, a worktable 2, a clamping mechanism 3, a fixing base 5, a cutting mechanism, and a feed mechanism.

[0040] Rack 1 The frame 1 is usually made of high-strength steel welded together and subjected to aging treatment to ensure its long-term stability and vibration resistance.

[0041] Worktable 2 and positioning mechanism Please see Figures 1-2At the top of the frame 1, a worktable 2 is fixedly installed. The worktable 2 is a precision-machined metal plate. Its upper surface is used to place and position the metal tube workpiece to be cut. A clamping mechanism 3 capable of clamping the workpiece is set above the worktable 2. A long strip opening that runs through its upper and lower surfaces, namely the cutting groove 4, is also opened on the worktable 2. The width of the groove is slightly larger than the thickness of the blade 602, which will be described later. Please see Figures 1-4 In order to achieve precise guidance of the workpiece, two guide plates 7 are installed on the worktable 2, which are parallel to each other and perpendicular to the plane of the worktable 2. The space between these two guide plates 7 forms a material guiding space. The metal tube workpiece can move freely in this space along its axis to adjust the cutting length. The position of the blade groove 4 is designed to pass through this material guiding space to ensure that the blade 602 can accurately cut the workpiece located in the material guiding space when it is raised.

[0042] Clamping mechanism 3 In this embodiment, the clamping mechanism 3 includes two fixed clamps 301, two horizontal clamps 302, two horizontal drive members 303, a vertical clamp 304, and a vertical drive member 305. Please refer to the details. Figure 4 On one side of the material guiding space, two fixed clamps 301 are fixedly installed, respectively located on both sides of the knife groove 4. Each fixed clamp 301 has a vertical clamping surface that contacts the workpiece. On the other side of the material guiding space, opposite to the two fixed clamps 301, two horizontally movable clamps 302 are provided. On the side of the two horizontal clamps 302 away from the fixed clamps 301, two horizontal driving members 303 are provided to drive the two horizontal clamps 302 closer to or away from the fixed clamps 301 respectively. For example, the horizontal driving member 303 can be a double-acting cylinder or a hydraulic cylinder, with its cylinder body fixed on the frame 1 or the worktable 2, and its piston rod connected to the horizontal clamps 302. When the horizontal driving member 303 extends, it drives the horizontal clamps 302 to move toward the fixed clamps 301, thereby cooperating with the fixed clamps 301 to clamp the workpiece in the horizontal direction. Please see Figure 4 Above the material guiding space, there is a vertical clamp 304 that can move vertically up and down. A vertical drive 305, such as one or more guide cylinders, is fixed to the top of the guide plate 7 by a mounting bracket. Its piston rod is connected downward to the vertical clamp 304. When the vertical drive 305 extends, it drives the vertical clamp 304 to move downward, pressing the upper surface of the workpiece, thereby cooperating with the upper surface of the worktable 2 to clamp the workpiece from the vertical direction. This clamping method, which allows for independent horizontal and vertical control, is particularly effective for clamping round tubes, preventing them from rolling. The contact surface of the clamp can be inlaid with polyurethane or rubber pads as needed to increase friction and avoid scratching the tube surface.

[0043] Built-in tilting cutting structure Please see Figure 2 Inside the frame 1, in the space below the worktable 2, a fixed base 5 is fixedly installed. The fixed base 5 can be securely connected to the crossbeam or side wall of the frame 1 by bolts or welding; please refer to Figures 5-7 The upper part of the fixed seat 5 is machined with an inclined, flat guide slope. In this embodiment, the inclination angle of the guide slope is preferably 65 degrees relative to the horizontal plane. The selection of this angle allows the cutting mechanism to contact the workpiece with a near-optimal cutting geometry angle when it moves upward. Please see Figure 11 On the guide slope of the fixed seat 5, two parallel linear guide rails 8 are fixedly installed, and the extension direction of the guide rails 8 is exactly the same as that of the guide slope. The cutting mechanism includes a tool holder 601, a blade 602, and a cutting motor 603. (See also...) Figure 9 and Figure 10 The bottom surface of the tool holder 601 is fixedly equipped with multiple sliding blocks 9 that match the linear guide rail 8. Please refer to [link / reference]. Figures 5-7 Through the cooperation of these sliding blocks 9 and guide rail 8, the entire tool holder 601 can slide smoothly up and down along the guide slope. The tool holder 601 is usually welded from cast iron or thick-walled steel plate and has sufficient mass and rigidity to absorb cutting vibration. The blade 602 is a circular carbide saw blade or high-speed steel saw blade, which is rotatably mounted at the front end of the tool holder 601 via a high-precision rotating shaft 604 and bearing assembly. The plane of the blade 602 is coordinated with the direction of the guide slope to ensure that it can eventually pass through the cutting groove 4 of the worktable 2. Please see Figure 6 and Figure 7 The cutting motor 603 is installed at the rear of the tool holder 601. A drive pulley 606 is mounted on its output shaft. A driven pulley 605 is mounted at the rear end of the blade 602 rotating shaft 604. The drive pulley 606 and the driven pulley 605 are connected by one or more V-shaped transmission belts. After the cutting motor 603 is started, it drives the blade 602 to rotate at high speed through belt drive.

[0044] Infeed mechanism In this embodiment, the feed mechanism includes a lead screw 1001, a transmission nut 1002, and a feed motor 1003; Please see Figure 11In the center of the guide slope of the fixed seat 5, a drive groove 501 is provided along its length direction. Bearing seats are installed at both ends of the drive groove 501. A high-precision ball screw 1001 is rotatably supported between the two bearing seats. The axis of the screw 1001 is parallel to the guide slope. Please see Figure 3 , Figure 5 , Figure 6 , Figure 7 as well as Figure 11 The feed motor 1003 is a servo motor and is mounted on the bottom of the fixed base 5 through a reducer. Its output shaft is connected to the lower end of the lead screw 1001 through a coupling. Please see Figure 9 and Figure 10 At the bottom of the tool holder 601, a transmission nut 1002 that matches the lead screw 1001 is fixedly installed. The transmission nut 1002 extends into the drive groove 501 and is sleeved on the lead screw 1001. When the servo motor rotates according to the command, it can drive the lead screw 1001 to rotate. The rotational motion of the lead screw 1001 is converted into linear motion through the transmission nut 1002, thereby driving the entire tool holder 601 to move smoothly up or down along the guide slope with the rotating blade 602.

[0045] Safety and Limiting Structure Please see Figures 5-7 To prevent the tool holder 601 from sliding down excessively, two stop blocks 11 are fixedly installed at the bottom of the guide slope. When the tool holder 601 is driven to reset downwards by the feed motor 1003, the bottom of the tool holder 601 will contact the two stop blocks 11, thereby forming a physical stop to prevent the blade 602 from colliding violently with the frame 1, thus avoiding serious equipment damage and possible personal injury.

[0046] Cleaning and chip removal system Since cutting metal generates a large amount of ferromagnetic chips, this embodiment also integrates a highly efficient cleaning system; Please see Figure 8 and Figure 9 On the tool holder 601, below the blade 602, a wire wheel 14 is rotatably mounted via a bracket. The outer circumferential surface of the wire wheel 14 maintains slight contact with the side or tooth root of the blade 602. The wheel body of the wire wheel 14 is usually made of plastic or metal, and its circumference is densely covered with fine steel wires. When the blade 602 rotates at high speed, it will drive the wire wheel 14 to rotate with it by friction. Using this relative motion, the fine steel wires on the wire wheel 14 can effectively scrape off the chips, oil stains, etc. adhering to the blade 602, thus playing a self-cleaning role. Please see Figure 1 , Figure 2 as well as Figure 8 Inside the frame 1, directly below the projection area of ​​the blade 602, there is a magnetic chip conveyor 13. The magnetic chip conveyor 13 is a standard outsourced component. Its core structure includes a closed stainless steel working panel, an internally circulating permanent magnet chain, a drive motor, and a chip outlet. During operation, the iron chips falling on it are attracted to the stainless steel panel by the magnet below and carried by the chain to the chip outlet, where they are scraped off by the scraper and fall into the chip collection box, while the coolant flows out from another outlet. Please see Figures 8-10 To ensure that the chips fall accurately into the magnetic chip conveyor 13, a dustproof plate assembly 12 is also installed on the tool holder 601. The dustproof plate assembly 12 is made of multiple metal plates (such as thin steel plates) welded or riveted together. The dustproof plate assembly 12 encloses the cutting motor 603, the driving pulley 606, the driven pulley 605, the transmission belt, the sliding block 9, and the transmission nut 1002 like an outer shell. These dustproof plates not only prevent chips from splashing into these precision components, but their specific tilt angle design also allows the chips falling from the blade 602 and the wire wheel 14 to be guided to slide down the plate wall and eventually fall into the magnetic chip conveyor 13 below.

[0047] External protection Please see Figures 1-3 The frame 1 is enclosed by a protective plate assembly 15, which is usually made of metal plate or sturdy transparent polycarbonate plate and is equipped with an inspection door with a safety lock. The protective plate assembly 15 completely covers the internal fixed base 5, the entire cutting mechanism, the feed mechanism and the magnetic chip conveyor 13. The operator can only access the workpiece on the worktable 2 and the clamping mechanism 3, which greatly improves the safety of operation.

[0048] The operating principle of the cutting device in this embodiment is as follows: First, the long metal tube is fed through the guide space to the required cutting length. The horizontal drive 303 and vertical drive 305 are activated, causing the horizontal clamp 302 and vertical clamp 304 to move simultaneously, firmly fixing the workpiece on the worktable 2. Then, the cutting motor 603 starts, driving the blade 602 to rotate at high speed. Next, the feed motor 1003 (servo motor) starts according to the preset program, driving the lead screw 1001 to rotate, causing the entire cutting mechanism to move upward along the inclined guide slope. When the rotating blade 602 passes through the cutting groove 4 and contacts the metal tube, cutting is performed. The torque and position control of the servo motor ensures a smooth feed speed. After cutting, the feed motor 1003 reverses, quickly retracting the cutting mechanism downward to its original position. The clamping mechanism 3 is released, and the cut short tube can be removed. The remaining long tube is fed in again to enter the next cycle. Throughout the cutting process, the wire wheel 14 continuously cleans the blade 602. Chips and coolant fall onto the dustproof plate assembly 12 and are guided to the magnetic chip conveyor 13 for automatic discharge.

[0049] The embodiments of the present invention have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of the present invention can be combined with each other.
