Description

Technical Field

[0001] This application relates to the field of PVC window and door processing technology, and more specifically, to a high-efficiency cutting device for PVC materials used in PVC window and door processing. Background Technology

[0002] In the production of PVC-U doors and windows, cutting the corners at the ends of the PVC-U frames is a critical processing step. Traditional cutting equipment requires manual positioning of the frame after adjusting the cutting angle of the cutting blade. To ensure that the width and length of the doors and windows can be precisely spliced ​​into a right-angle structure at the ends after cutting, the corners at both ends of the frame need to be cut at 45°. However, manually positioning the cutting blade and the end of the frame by visual inspection introduces some deviation, easily resulting in over-cutting or under-cutting, leading to inconsistent frame dimensions. This makes it difficult for the assembled door and window corners to form a right-angle structure, affecting the aesthetics of the doors and windows. Multiple cutting adjustments are required, resulting in low cutting efficiency and difficulty in ensuring cutting accuracy, which easily leads to material waste and product size deviations, failing to meet the needs of large-scale production. In view of this, we propose a high-efficiency cutting device for PVC-U materials in the processing of PVC-U doors and windows. Utility Model Content

[0003] 1. Technical problems to be solved The purpose of this application is to provide a high-efficiency cutting device for PVC window and door processing, which solves the technical problems mentioned in the background art. It achieves this by using a square mold base with L-shaped corner grooves and rectangular guide grooves, along with two vertically arranged support plates. Each support plate has adjustable-spacing L-shaped plates and rulers, facilitating the guidance and installation of PVC window frames of different widths. This enables precise positioning and efficient cutting. Furthermore, by using two support plates, the length and width of the PVC window frames can be stacked separately and installed along the guides between the L-shaped plates and rulers on one support plate. This allows for efficient and precise cutting of the PVC window frame ends at a 45° angle. The cutting process ensures the dimensional accuracy and cut quality of the PVC window frame, reduces the scrap rate, improves the overall product quality, and significantly shortens the processing time for individual products.

[0004] 2. Technical Solution This application provides a high-efficiency cutting device for PVC materials in the processing of PVC doors and windows, comprising: a square fixed mold base, an L-shaped corner groove formed in the square fixed mold base, a rectangular guide groove formed along the diagonal direction of the square fixed mold base, the rectangular guide groove communicating with the L-shaped corner groove, a U-shaped seat fixedly provided at the corner of the upper surface of the square fixed mold base, a cutting machine rotatably mounted on the U-shaped seat, a support plate fixedly provided on each of the two sides of the square fixed mold base, a ruler plate fixedly provided on each support plate, an L-shaped plate slidably mounted on each support plate, a rectangular slot structure provided between the L-shaped plate and the ruler plate, and a PVC window frame movably inserted therein, the end of the PVC window frame being inserted into the L-shaped corner groove of the square fixed mold base.

[0005] By adopting the above technical solution, this cutting device is used for precise end corner cutting of PVC window frames, which are composed of doors and windows in terms of length and width. A square mold base serves as the basic component, with an L-shaped corner groove inside to accommodate and abut the ends of the PVC window frame, providing initial positioning of the ends. A rectangular guide groove along the diagonal of the square mold base, connected to the L-shaped corner groove, provides cutting guidance space for the cutting machine. A U-shaped bracket on the square mold base is used to mount the cutting machine, allowing the cutting components of the machine to cut along the rectangular guide groove. The 5° cutting process and the square fixed mold base simultaneously connect two support plates, which are set vertically. Each support plate is equipped with an L-shaped plate and a ruler with adjustable spacing. The L-shaped plate and the ruler are used to fix and guide the insertion of PVC window frames of different widths. The ruler provides a reference standard for measurement. At the same time, the width and length of PVC window frames can be processed separately, so that the width and length of PVC window frames can be accurately connected after the corner cutting. The separate stacking also avoids the problem of operation error, greatly improves the cutting and corner cutting efficiency, and reduces the scrap rate.

[0006] Optionally, each of the support plates is provided with a sliding groove, the sliding groove has a concave cross-section, the L-shaped plate is fixedly connected with a concave sliding strip, the concave sliding strip is slidably installed along the sliding groove, and each of the support plates is rotatably installed with a screw, the screw being threadedly connected to the concave sliding strip.

[0007] By adopting the above technical solution, when processing the corner cutting of PVC window frames of different widths, rotating the screw allows the L-shaped plate to slide along the slide groove through the concave slide bar, thereby adjusting the width of the rectangular slot structure to adapt to the guide insertion installation of different PVC window frames.

[0008] Optionally, each of the trays is threaded with a positioning bolt, the bottom end of which abuts against the upper surface of the PVC window frame.

[0009] By adopting the above technical solution, when the end of the PVC window frame is inserted into the L-shaped corner groove of the square fixed mold base, and the end of the PVC window frame is pressed against the inner end face of the L-shaped corner groove, the positioning bolt is locked to ensure accurate positioning of the PVC window frame, thereby avoiding movement of the PVC window frame during the cutting process and preventing deviation of the cut corner of the PVC window frame end.

[0010] Optionally, the pallet is provided with a beveled surface at one end near the square mold base, and the beveled surface overlaps with the inner wall of the rectangular guide groove.

[0011] By adopting the above technical solution, the beveled surface at the end of the pallet overlaps with the inner wall of the rectangular guide groove, allowing the waste material from the beveled corner of the PVC window frame to fall smoothly from the rectangular guide groove.

[0012] Optionally, the cutting machine includes a protective shell, on which a motor and a handle are fixedly installed, and inside which a belt mechanism is rotatably installed. The output end of the motor is connected to a cutting blade via the belt mechanism. The cutting blade is located at the upper part of a rectangular guide groove, and the projection line of the cutting blade coincides with the center line of the rectangular guide groove.

[0013] By adopting the above technical solution, the cutting machine equipment consists of a protective shell, a motor, a belt mechanism and a cutting blade. The motor drives the cutting blade to rotate at high speed through the belt mechanism, which can achieve the cutting effect. The cutting blade can move along the set moving path and can achieve the moving effect along the rectangular guide groove, thus realizing the corner cutting operation at the end of the plastic steel window frame.

[0014] Optionally, a fixing block is fixedly provided on the U-shaped seat, and an L-shaped shaft is rotatably provided on the U-shaped seat. One end of the L-shaped shaft is fixedly connected to the protective shell, and a return spring is detachably connected between the other end of the L-shaped shaft and the fixing block.

[0015] By adopting the above technical solution, the protective shell is rotatably mounted on the U-shaped seat via an L-shaped shaft, and a return spring is detachably connected between the L-shaped shaft and the fixed block. When the handle is released, the protective shell will rotate and return to its original position under the action of the return spring.

[0016] 3. Beneficial effects One or more technical solutions provided in this application have at least the following technical effects or advantages: By setting a square fixed mold base with L-shaped corner grooves and rectangular guide grooves, and cooperating with two vertically set support plates, each of which is equipped with L-shaped plates and ruler plates with adjustable spacing, it is easy to guide and install PVC window frames of different widths, achieving precise positioning and efficient cutting. Furthermore, by setting two support plates, the length and width of PVC window frames in doors and windows can be stacked separately and installed by inserting them along the guide between the L-shaped plates and ruler plates on one support plate. This enables efficient processing of precisely cutting the ends of PVC window frames at a 45° bevel. The cutting process ensures the dimensional accuracy and cut quality of the PVC window frames, reduces the scrap rate, improves the overall quality of the product, and greatly shortens the processing time of a single product.

A rectangular slot structure is provided between the L-shaped plate 4 and the ruler plate 3, and a PVC window frame 5 is movably inserted into it. The ends of the PVC window frame 5 are inserted into the L-shaped corner grooves 11 of the square mold base 1. This cutting device is used to perform precise corner cutting processing on the ends of the PVC window frame 5, which is composed of the length and width of the door and window. The square mold base 1 is used as the basic component, and the L-shaped corner grooves 11 inside are used to accommodate and abut the ends of the PVC window frame 5. The square mold base 1 serves as the initial positioning point for the ends of the PVC window frame 5. A rectangular guide groove 12, formed along the diagonal, connects to an L-shaped corner groove 11, providing cutting guidance space for the cutting machine 7. A U-shaped seat 6 is used to mount the cutting machine 7 on the square mold base 1, allowing the cutting components of the machine 7 to perform 45° cuts along the rectangular guide groove 12. The square mold base 1 also has two support plates 2 fixedly connected, with the two support plates 2 vertically positioned. Each support plate 2 has an adjustable L-shaped plate 4 and a ruler 3. The L-shaped plate 4 and ruler 3 are used to fix and guide the insertion of PVC window frames 5 of different widths. The ruler 3 provides a reference standard for measurement. Furthermore, the width and length of the PVC window frames 5 can be processed separately, allowing for precise alignment after corner cutting. Separate stacking also avoids operational errors, significantly improving cutting efficiency and reducing scrap rates.

[0019] Reference Figure 2 and Figure 3 Each support plate 2 is provided with a sliding groove 21, the sliding groove 21 has a concave cross-section, and an L-shaped plate 4 is fixedly connected to a concave sliding strip 41. The concave sliding strip 41 is slidably installed along the sliding groove 21. Each support plate 2 is rotatably installed with a screw 43, which is threadedly connected to the concave sliding strip 41. When processing the corners of the plastic steel window frame 5 with different widths, the screw 43 is rotated so that the L-shaped plate 4 slides along the sliding groove 21 through the concave sliding strip 41. The width of the rectangular slot structure can be adjusted to adapt to the guide insertion installation of different plastic steel window frames 5.

[0020] Reference Figure 2 and Figure 3Each support plate 2 is threaded with a positioning bolt 42. The bottom end of the positioning bolt 42 abuts against the upper surface of the PVC window frame 5. When the end of the PVC window frame 5 is inserted into the L-shaped corner groove 11 of the square fixed mold base 1 and the end of the PVC window frame 5 is pressed against the inner end face of the L-shaped corner groove 11, the positioning bolt 42 is locked to ensure that the PVC window frame 5 is accurately positioned and to prevent the PVC window frame 5 from moving during the cutting process, which would cause deviation in the cut corner of the PVC window frame 5.

[0021] Reference Figure 2 and Figure 3 The pallet 2 has a beveled surface 22 at one end near the square fixed mold base 1. The beveled surface 22 overlaps with the inner wall of the rectangular guide groove 12. The beveled surface 22 at the end of the pallet 2 overlaps with the inner wall of the rectangular guide groove 12, so that the waste material cut at the end of the plastic steel window frame 5 can fall smoothly from the rectangular guide groove 12.

[0022] Reference Figure 1 and Figure 4 The cutting machine equipment 7 includes a protective shell 71. A motor 72 and a handle 74 are fixedly installed on the outside of the protective shell 71.

[0023] Reference Figure 1 and Figure 4 A fixing block 61 is fixedly provided on the U-shaped seat 6. An L-shaped shaft 63 is rotatably provided on the U-shaped seat 6. One end of the L-shaped shaft 63 is fixedly connected to the protective shell 71. A return spring 62 is detachably connected between the other end of the L-shaped shaft 63 and the fixing block 61. The protective shell 71 is rotatably mounted on the U-shaped seat 6 via the L-shaped shaft 63. A return spring 62 is detachably connected between the L-shaped shaft 63 and the fixing block 61. When the handle 74 is released, the protective shell 71 will rotate and return to its original position under the action of the return spring 62.

[0024] Working principle: When using this cutting device, first, neatly stack the pre-set PVC window frames 5 to be cut together, separating the PVC window frames 5 in the length and width directions of the doors and windows. The PVC window frames 5 are placed on the support plate 2, and then the PVC window frames 5 are guided into the rectangular slot structure between the L-shaped plate 4 and the ruler plate 3, and finally inserted into the L-shaped corner groove 11 of the square mold base 1. The end of the PVC window frame 5 abuts against the inner end face of the L-shaped corner groove 11, and the size of the PVC window frame 5 can be verified by the corresponding ruler plate 3, avoiding the mixing of different PVC window frames 5, and facilitating the quick use of the corresponding PVC window frame 5 when assembling doors and windows. Rotating the screw 43 can adjust the position of the L-shaped plate 4 and the size of the rectangular slot structure to adapt to the cutting and processing of PVC window frames 5 of different widths. By tightening the positioning bolt 42, the bottom end of the positioning bolt 42 is... Press the upper surface of the PVC window frame 5 firmly to ensure stability during cutting. Start the motor 72 on the cutting machine 7. The motor 72 drives the cutting blade 73 to rotate at high speed through the belt mechanism 75. Since the cutting blade 73 is located on the upper part of the rectangular guide groove 12 and the projection line of the cutting blade 73 coincides with the center line of the rectangular guide groove 12, by pressing the handle 74, the cutting blade 73 can accurately cut a 45° bevel at the end of the PVC window frame 5 along the rectangular guide groove 12. After cutting, under the action of the return spring 62, the cutting machine 7 automatically returns to the initial position, then flips the PVC window frame 5 and accurately cuts a 45° bevel at the other end of the PVC window frame 5. Compared with traditional cutting equipment, there is no need to frequently operate to adjust the cutting angle of the cutting blade 73, which is convenient to use and greatly improves cutting efficiency.
