Description

Technical Field

[0001] This utility model relates to the field of door and window cutting and processing, specifically a cutting and processing device for doors and windows. Background Technology

[0002] Before assembly, door and window profiles need to be cut to specified dimensions. Existing cutting saws used for cutting door and window profiles generate high temperatures due to continuous cutting operations. After prolonged use, the saw blades are prone to deformation, affecting cutting accuracy and leading to frequent blade replacements, which increases the cost of cutting, processing, and maintenance. Utility Model Content

[0003] The purpose of this invention is to provide a cutting and processing device for doors and windows, which can solve the technical problem that existing cutting saw blades are prone to deformation after long-term use, resulting in high replacement frequency. By utilizing the cutting saw blade to simultaneously enter the cutting kerf and cooling box during cutting, the cutting saw blade can be cooled and cooled in time after cutting, thereby improving the service life of the cutting saw blade and reducing the cost of cutting, processing and maintenance.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A cutting and processing device for doors and windows includes a body with a cutting table for placing door and window profiles. A sliding plate is slidably connected to one side of the cutting table, and a cutting saw blade is mounted on the sliding plate. A cutting slit is provided on the cutting table to cooperate with the cutting saw blade. A cooling box is provided below the cutting slit, and a through hole communicating with the cutting slit is provided on one side of the cooling box. The cutting saw blade enters both the cutting slit and the through hole simultaneously. An air outlet is provided on the body, communicating with the other side of the cooling box, and a cooling fan is provided at the air outlet.

[0006] Furthermore, the cutting table is provided with multiple chip-extraction holes that communicate with the cooling box, the chip-extraction holes surround the periphery of the cutting kerf, and the side of the machine body is provided with a chip discharge port that communicates with the cooling box.

[0007] Furthermore, the bottom of the air outlet is higher than the bottom of the cooling box, and a filter screen is provided at the air outlet.

[0008] Furthermore, the cutting table is equipped with a protective cover, and the cutting slit and chip leakage hole are both located inside the protective cover.

[0009] Furthermore, a feeding table is slidably connected to the machine body along the longitudinal direction, and both the feeding table and the cutting table are equipped with clamping cylinders for use with door and window profiles.

[0010] Furthermore, the machine body is provided with a guide rod and a feeding cylinder, the bottom of the feeding platform is provided with a slider, the guide rod passes through the slider and is slidably connected to it, and the feeding platform is connected to the movable end of the feeding cylinder.

[0011] Furthermore, the cutting table is provided with a material discharge port, which is located on one side of the cutting seam, and the machine body is provided with a material discharge channel communicating with the material discharge port, which extends to the side of the machine body.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The structure of this utility model has a cooling box set below the cutting seam. One side of the cooling box has a through hole that communicates with the cutting seam. When the cutting saw blade cuts the door and window profiles on the cutting table, it enters both the cutting seam and the through hole at the same time. This structure allows the cooling box to quickly cool down the cutting saw blade as it enters the cutting seam and the through hole after cutting, which greatly reduces the temperature of the cutting saw blade and avoids deformation of the cutting saw blade due to high temperature. This extends the service life of the cutting saw blade and reduces the cost of cutting and maintenance.

[0014] 2. An air outlet connected to the other side of the cooling box is provided on the machine body. A cooling fan is installed at the air outlet. This structure creates a cooling airflow that moves from the perforation towards the air outlet inside the cooling box. This allows the airflow that has cooled the cutting saw blade to be discharged from the air outlet in a timely manner, avoiding the accumulation of airflow with high temperature inside the cooling box. This improves the smoothness of the cooling airflow, reduces the temperature inside the cooling box, and improves the cooling effect on the cutting saw blade. Attached Figure Description

It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0024] Reference Figure 1 and Figure 2This utility model describes a cutting and processing device for doors and windows. The main structure includes a body 1, which serves as the primary cutting and processing structure. It is typically composed of a metal box structure. The body 1 has a cutting table 3 for placing door and window profiles 2. Preferably, the cutting table 3 is L-shaped, with the door and window profiles 2 placed at the corner of the L-shape for easy fixation. A sliding plate 4 is slidably connected to one side of the cutting table 3. The sliding plate 4 is driven by any existing drive structure, such as a lead screw and nut or an electric cylinder. A cutting saw blade 5 is mounted on the sliding plate 4. Specifically, a cutting electric saw blade is fixed to the sliding plate 4 by welding or bolting. The machine uses a cutting saw blade 5 driven by a cutting motor. During cutting, a sliding plate 4 moves the cutting saw blade 5 towards the door and window profile 2 to cut the profile. The cutting table 3 has a cutting slit 6 for use with the cutting saw blade 5. The cutting slit 6 allows the cutting saw blade 5 to enter the cutting slit 6 after cutting the door and window profile 2, thus achieving a complete cut. A cooling box 7 is located below the cutting slit 6. The cooling box 7 is fixed inside the machine body 1 by welding or bolts and is used to cool the cutting saw blade 5. One side of the cooling box 7 has a through hole 8 communicating with the cutting slit 6, located below the cutting slit 6. The cutting saw blade 5 simultaneously enters the cutting slit 6 and the perforation 8. This structure allows the cutting saw blade 5 to simultaneously enter the cutting slit 6 and the perforation 8 below when the sliding plate 4 drives the cutting saw blade 5 to cut the door and window profile 2. After cutting, the cutting saw blade 5 rotates into the cooling box 7, where it is cooled down in time. This cooling operation, performed after each cut, significantly reduces the temperature of the cutting saw blade 5 during continuous cutting, preventing bending and deformation, extending its service life, and reducing cutting and maintenance costs. The machine body 1 is equipped with a cooling box 7. The other side is connected to the air outlet 9. Specifically, the other side of the cooling box 7 is open or an air outlet 9 is also set at the corresponding position. A cooling fan 10 is provided at the air outlet 9. When the cooling fan 10 is running, it exhausts the air inside the cooling box 7. Outside air enters the cooling box 7 through the perforation 8. This structure makes the cooling airflow inside the cooling box 7 move from the perforation 8 toward the air outlet 9. When the cutting saw blade 5 enters the cooling box 7 after passing through the perforation 8, the cooling airflow comes into contact with the cutting saw blade 5 and exchanges heat. The heated air is discharged from the air outlet 9 in time, which reduces the temperature inside the cooling box 7 and improves the cooling effect on the cutting saw blade 5.

[0025] Preferably, the cutting table 3 is provided with multiple chip-leaking holes 11 that communicate with the cooling box 7. The chip-leaking holes 11 pass through the cutting table 3 and communicate with the cooling box 7. This structure generates suction at the multiple chip-leaking holes 11, allowing the metal chips after cutting to pass through the chip-leaking holes 11 under the action of suction and enter the cooling box 7. The chip-leaking holes 11 surround the periphery of the cutting kerf 6, which can suck away most of the chips generated during cutting. The side of the machine body 1 is provided with a chip discharge port 12 that communicates with the cooling box 7. The metal chips that enter the cooling box 7 accumulate at the bottom of the cooling box 7 under the action of gravity. After a period of time, the chip discharge port 12 is opened to discharge the chips accumulated at the bottom of the cooling box 7. This structure improves the collection effect of the chips generated during cutting, avoids the chips generated during cutting from splashing onto the surrounding equipment and environment, and ensures the cleanliness of the cutting processing environment.

[0026] Preferred, refer to Figure 3 The bottom of the air outlet 9 is higher than the bottom of the cooling box 7 to prevent metal debris from accumulating at the bottom of the cooling box 7 and clogging the air outlet 9. The air outlet 9 is equipped with a filter screen 13, which can filter out debris and impurities when the air is discharged, preventing debris and impurities from being discharged from the air outlet 9 and avoiding damage to the cooling fan 10, thus ensuring the smooth cooling operation of the cutting saw blade 5.

[0027] Preferably, the cutting table 3 is provided with a protective cover 14, which is open on one side facing the cutting saw blade 5, so that the cutting saw blade 5 can enter the interior of the protective cover 14 after cutting the door and window profile 2. The cutting slit 6 and the chip leakage hole 11 are both located inside the protective cover 14. The protective cover 14 can protect the cutting position and prevent the chips generated during cutting from splashing into the surrounding environment. The chips are collected inside the protective cover 14 and then fall from the cutting slit 6 and the chip leakage hole 11, which further improves the collection effect of cutting chips.

[0028] Preferred, refer to Figure 5 The machine body 1 is longitudinally slidably connected to a feeding table 15, the sliding direction of which is perpendicular to the sliding direction of the slide plate 4. Both the feeding table 15 and the cutting table 3 are fixed with clamping cylinders 16 for use with the door and window profiles 2 by welding or bolts. The movable end of the clamping cylinder 16 is equipped with a rubber clamp. When the clamping cylinder 16 extends, the rubber clamp contacts the door and window profiles 2 to perform a clamping operation. After clamping the door and window profiles 2, the clamping cylinder 16 on the feeding table 15 drives them to move toward the cutting table 3, realizing automatic feeding of the door and window profiles 2 after cutting, ensuring the continuity of cutting. After the door and window profiles 2 are fed, the clamping cylinder 16 on the cutting table 3 clamps them, ensuring the stability of the door and window profiles 2 during cutting and ensuring the accuracy of cutting processing.

[0029] Preferred, refer to Figure 6 The machine body 1 is fixed with a guide rod 17 and a feeding cylinder 18 by welding or bolts. The bottom of the feeding table 15 is fixed with a slider 19 by welding or bolts. The guide rod 17 passes through the slider 19 and is slidably connected to it. The feeding table 15 is connected to the movable end of the feeding cylinder 18 by welding or bolts. This structure drives the slider 19 at the bottom of the feeding table 15 to slide along the guide rod 17 when the feeding cylinder 18 extends, which improves the stability of the sliding movement of the feeding table 15 and ensures the accuracy and stability of feeding the door and window profiles 2.

[0030] Preferred, refer to Figure 4 The cutting table 3 is provided with a material discharge port 20. The cut door and window profiles 2 fall from the material discharge port 20. The material discharge port 20 is located on one side of the cutting seam 6. The machine body 1 is provided with a material discharge channel 21 that communicates with the material discharge port 20. The material discharge channel 21 is inclined and extends to the side of the machine body 1. The material discharge channel 21 penetrates the side of the machine body 1. This structure allows the cut door and window profiles 2 to fall to the material discharge port 20 on one side after being pushed by the subsequently fed door and window profiles 2. Then, they fall out from the side of the machine body 1 along the inclined material discharge channel 21, making the discharge of the cut door and window profiles 2 smoother and more convenient.

[0031] Working Principle: This invention features a cooling box 7 located below the cutting slit 6. One side of the cooling box 7 has a through hole 8 communicating with the cutting slit 6. When the cutting saw blade 5 cuts the door and window profile 2 on the cutting table 3, it simultaneously enters both the cutting slit 6 and the through hole 8. This structure allows the cooling box 7 to rapidly cool the cutting saw blade 5 as it enters the cutting slit 6 and through hole 8, significantly reducing its temperature and preventing deformation due to high temperatures, thus extending the lifespan of the cutting saw blade 5. The machine body 1 has an air outlet 9 connected to the other side of the cooling box 7. A cooling fan 10 is installed at the air outlet 9. This structure allows the cooling airflow inside the cooling box 7 to move from the perforation 8 toward the air outlet 9. This ensures that the airflow after cooling the cutting saw blade 5 is discharged from the air outlet 9 in a timely manner, avoiding the accumulation of airflow inside the cooling box 7 after the temperature rises. This improves the smoothness of the cooling airflow, reduces the temperature inside the cooling box 7, and improves the cooling effect on the cutting saw blade 5.
