Description

Technical Field

[0001] This utility model relates to the field of cutting device technology, and in particular to a cutting device for processing sliding doors. Background Technology

[0002] The processing of metal tubing for sliding doors requires multiple steps such as end cutting, grooving, and bevel cutting. High-precision CNC composite machine tools are expensive, far exceeding the affordability of small and medium-sized enterprises. Therefore, most manufacturers use single-function equipment. When completing different processes, multiple clamping and machine tool changes are required, resulting in inconsistent positioning references, low production efficiency, and easy accumulation of errors, which affects processing accuracy. Currently, the position and angle adjustment of the cutting unit in existing cutting equipment is often not flexible enough, and it cannot effectively adapt to its special cross-sectional shape. The locking is also not convenient and reliable enough, and displacement is easy to occur during processing, which affects the cutting quality. Utility Model Content

Detailed Implementation

[0017] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0019] In the description of this utility model, it should be understood that the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] In this embodiment, as Figure 1 and Figure 2 As shown, a cutting device for processing sliding doors includes: a base plate 1; a telescopic member 2, the fixed end of which is disposed on the base plate 1; an adjusting frame 3, which is connected to the output end of the telescopic member 2, and the adjusting frame 3 is arranged parallel to the telescopic member 2; the adjusting frame 3 is T-shaped, and each of its three protruding ends is machined with a limiting groove 301; two first cutting components are respectively disposed on the two protruding ends in the horizontal direction of the adjusting frame 3; the first cutting components include a first slider 4, a support arm 5, a mounting plate 6, and a first cutting tool 7; the first slider 4 is slidably disposed in the limiting groove 301, the support arm 5 is disposed on the outer wall of the first slider 4, the mounting plate 6 is rotatably connected to the support arm 5, and the first cutting tool 7 is disposed on the mounting plate 6.

[0021] Thus, the telescopic component 2 (which can be a cylinder or an electric push rod) can drive the entire adjusting frame 3 and the cutting assembly mounted on it to rise and fall vertically to accommodate pipes of different heights or to perform feed cutting. The two first cutting assemblies can slide independently on two convex arms in the horizontal direction of the adjusting frame 3, thereby adjusting the distance between the two cutting points to achieve synchronous or separate processing of both ends of door frame pipes of different lengths; Specifically, the telescopic component 2 is fixed to the base plate 1 by bolts, and its output end is fixedly connected to the center of the vertical part of the adjusting frame 3 by a flange or connecting block.

[0022] In some embodiments, such as Figure 3 As shown, the locking mechanism is used to fix the first slider 4 on the adjusting frame 3; the locking mechanism includes at least one threaded pin 8 and a nut 9 that mates with the threaded pin 8; the bottom end of the threaded pin 8 is connected to the first slider 4, and its top end passes upward through the through slot 302 opened on the adjusting frame 3 and is connected to the nut 9.

[0023] Specifically, after the first slider 4 moves to the target position, the nut 9 is tightened with a wrench. The nut 9 presses down on the upper surface of the adjusting frame 3. (In actual use, a washer can be installed between the nut 9 and the adjusting frame 3.) At the same time, the threaded pin 8 pulls the first slider 4 upward, so that a huge frictional force is generated between the first slider 4 and the groove wall of the limiting slide groove 301, thereby achieving a firm lock. The through groove 302 is elongated, providing travel space for the movement of the threaded pin 8, and also serving to prevent rotation.

[0024] In some embodiments, such as Figure 3 As shown, the rotatable connection between the mounting plate 6 and the support arm 5 is an adjustable hinge, which allows the mounting plate 6 to be adjusted to 45 degrees or 90 degrees relative to the horizontal plane, and can be fixed by bolts; Specifically, the end of the support arm 5 is provided with a connecting lug with a shaft hole. The mounting plate 6 is rotatably connected to this connecting lug through a hinge shaft. When the angle needs to be adjusted, first loosen the bolts used for fixing, rotate the mounting plate 6 to the preset position of 0° (horizontal), 45° or 90° (vertical), so that the positioning hole on the plate is aligned with the threaded hole of the corresponding angle on the support arm, and finally tighten the bolts to complete the fixing.

[0025] In some embodiments, such as Figure 2 and Figure 4 As shown, the second cutting component is disposed on the protruding end in the vertical direction of the adjusting frame 3; The second cutting assembly includes: a second slider 10, which is slidably disposed in a vertical limiting groove 301; a threaded sleeve 11, which is fixedly embedded in the second slider 10; a threaded rod 12, which is threadedly engaged with the threaded sleeve 11, and the threaded rod 12 is connected to the adjusting frame 3 through a bearing; and a second cutting tool 13, which is disposed on the outer wall of the second slider 10. Specifically, one end of the threaded rod 12 is mounted on the top of the adjusting frame 3 via a bearing seat, and a handwheel can be installed at the other end. Rotating the handwheel drives the threaded rod 12 to rotate. Since the threaded sleeve 11 is fixed inside the second slider 10 and cannot rotate, the rotational motion of the threaded rod 12 is converted into the precise linear motion of the second slider 10 together with the second cutting tool 13 along the vertical limiting groove 301, thereby achieving smooth and controllable feed cutting, which is particularly suitable for grooving operations on the side of pipes. It should be noted that the drive motor of the second cutting tool 13 can be purchased as an integrated electric engraving machine or milling spindle, and its base can be directly fixed to the outer wall of the second slider 10.

[0026] In some embodiments, such as Figure 2 As shown, the second cutting tool 13 includes a drive motor, a rotating shaft driven by the drive motor, and a cutter head fixedly mounted on the rotating shaft; Specifically, its structure is similar to the first cutting tool 7, and different shapes and sizes of cutter heads (such as milling cutters, grooving saw blades, etc.) can be selected according to the grooving requirements.

[0027] In some embodiments, such as Figure 5 As shown, a groove 101 is provided on the base plate 1, and a workpiece clamping mechanism is provided in the groove 101; The workpiece clamping mechanism includes: a rectangular plate 15, which is slidably disposed in the groove 101; a limiting plate 16, which is connected to the base plate 1 and slidably engages with the rectangular groove 1501 opened at the bottom of the rectangular plate 15 to restrict the movement path of the rectangular plate 15; at least one card holder 17, which is disposed on the top of the rectangular plate 15; the card holder 17 is provided with a strip groove 1701, and a V-shaped groove 1702 is provided in the middle of the strip groove 1701, so that the cross-section of the strip groove 1701 is stepped.

[0028] Specifically, the metal tubing to be processed for the sliding door is placed horizontally within the strip grooves 1701 of the two mounting seats 17. The bottom surface of the tubing contacts the stepped surface of the strip groove, while its sides fall into the V-shaped groove 1702. The V-shaped structure serves to automatically center and initially limit the movement. The stepped design of the strip groove allows it to accommodate both square and flat rectangular tubing. It should be noted that the rectangular plate 15 can be finely adjusted within the groove 101 to precisely position the cutting location of the pipe before cutting. After adjustment, the rectangular plate 15 can be fixed to the base plate 1 using additional set screws or pressure plates.

[0029] In some embodiments, such as Figure 6 As shown, an elastic pad 18 is fixed inside the stepped strip groove 1701 by screws; Specifically, the elastic pad 18 can be made of materials such as rubber or polyurethane. It is pressed between the pipe and the retainer 17, which increases the friction to prevent the pipe from sliding during cutting, buffers vibration, and prevents the hard retainer from directly scratching the surface of the pipe (the pipe is a standard part).

[0030] In some embodiments, such as Figure 1 As shown, slide rails 14 are symmetrically arranged on both sides of the vertical protrusion of the adjustment frame 3, and the bottom end of the slide rails 14 is fixedly connected to the base plate 1. Specifically, the slide rail 14 cooperates with the slider (not shown separately in the figure) fixed on the adjusting frame 3. When the telescopic component 2 pushes the adjusting frame 3 to rise and fall, the slide rail 14 provides additional guidance and support, which greatly enhances the rigidity and stability of the entire frame under cutting force, prevents the frame from shaking, and further ensures the cutting accuracy.

[0031] In some embodiments, such as Figure 2 As shown, the first cutting tool 7 includes a drive motor 701, a rotating shaft 702 driven by the drive motor 701, and a cutter head 703 fixedly mounted on the rotating shaft 702; Specifically, the drive motor 701 is fixed to the mounting plate 6 by bolts, and its output shaft is connected to the rotating shaft 702 by a coupling, or an electric spindle with its own rotating shaft can be used directly. The cutter head 703 (such as a cutting wheel or carbide saw blade) is fastened to the end of the rotating shaft 702 by a flange and a nut.

[0032] The working principle of this application is illustrated below with a preferred embodiment: First, based on the length of the sliding door tube to be processed and the required cutting or grooving position, the device is preset. The tube is placed in the strip groove 1701 of the two card seats 17, and the elastic pad 18 is used to increase friction and prevent slippage. The rectangular plate 15 is pushed to slide in the groove 101 of the bottom plate, so that the area to be processed on the tube is aligned with the corresponding cutting tool. Then the rectangular plate is locked (the rectangular plate 15 can be locked by external bolts, or it can be held by hand during cutting). Loosen the nuts 9 on the two first sliders 4, slide the two first cutting components to the positions where the tube ends need to be cut, and then tighten the nuts 9 to lock them. If a 45° bevel cut is required at the end, loosen the fixing bolts of the mounting plate 6, rotate it 45° and then re-tighten it; rotate the handwheel of the threaded rod 12 to adjust the second cutting tool 13 to the height position where the grooving is required on the side of the tube. The motor of the first cutting blade 7 is started. After the cutter head 703 rotates at high speed, the telescopic component 2 is retracted, driving the entire adjusting frame 3 to move downwards. The two first cutting blades 7 then simultaneously cut both ends of the pipe. After cutting is completed, the telescopic component 2 returns to its original position. Start the motor of the second cutting tool 13, and then slowly turn the handwheel to drive the second cutting tool 13 to feed smoothly through the threaded rod 12, and mill the required groove on the side of the pipe. After the grooving is completed, turn the handwheel in the opposite direction to retract the tool.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
