Metal materials for doors and windows are divided into steel door and window materials and aluminum alloy door and window materials. Compared with wooden doors and windows, metal doors and windows have the advantages of small deformation, good durability and less shading. Compared with traditional wooden doors and windows, metal doors and windows require the use of mechanical processing equipment during processing to facilitate cutting or cutting operations. In the existing processing and cutting of metal doors and windows, circular saws are generally required to process the door and window workpieces.

[0003] According to the Chinese patent with the announcement number CN118106552B, a metal door and window cutting device is disclosed.

[0004] According to the Chinese patent with the announcement number CN213969295U, a production device for thermal-break aluminum doors and windows is disclosed. The utility model realizes the function of resetting the cutting device by holding the handle tightly and pressing down the cutting device to cut the profile for thermal-break aluminum doors and windows, and releasing the handle to make the reset spring rebound, thereby realizing the function of resetting the cutting device, blocking the chips and small pieces generated by cutting by the baffle plate, and driving the motor to rotate to generate negative pressure wind by starting the motor to suck the chips and small pieces into the chip collection box, and sliding them into the corresponding device for centralized treatment through the chute, thereby realizing the function of centralized treatment of the chips and small pieces generated by cutting and protecting the personal safety of the staff;

The cutting of the door and window profiles is positioned and clamped to prevent deviation through the synchronous movement of the lateral clamping seat and the longitudinal extrusion block of the clamping mechanism.

[0020] 1.

[0021] 2. In the metal door and window cutting device, when the blade of the circular saw moves into the cutting opening and completes the cutting of the metal door and window profile material, the proximity switch on the lower side of the cutting table will sense the approach of the blade, thereby driving the cylinder a through the PLC controller to drive the roller on the cross arm to move downward, and through the elastic reset action of the reset spring, the longitudinal extrusion block is pulled to rotate and slide in the opposite direction along the arc track, so that the reset rotating longitudinal extrusion block will push the profile waste away from the blade of the circular saw, so that the cut profile waste will fall into the receiving mechanism between the discharging frames;

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 12 The present invention provides a technical solution: a metal door and window cutting device, comprising a cutting table 1, a circular saw 3 and a clamping mechanism 5, a feeding roller 7 for conveying door and window profiles is arranged on one side of the cutting table 1, a guide wheel 2 is symmetrically arranged on the side of the cutting table 1 close to the feeding roller 7, the top of the cutting table 1 is also rotatably connected to the circular saw 3 through a hinge seat 301, and a discharge frame 4 is integrally formed on the side of the cutting table 1 away from the feeding roller 7.

[0039] A balance wheel 302 is fixed to one end of the rotating shaft in the middle of the articulated seat 301, and a connecting rod 303 is movably connected to one side of the balance wheel 302. The lower end of the connecting rod 303 is movably connected to the tail of the telescopic arm 305. A slide rail seat 304 slidably connected to the tail of the telescopic arm 305 is embedded on the side of the cutting table 1 close to the articulated seat 301. A material receiving mechanism 6 is arranged on the inner side of the discharge frame 4. The material receiving mechanism 6 includes a tic-tac-toe frame 601 movably connected to the inner side of the discharge frame 4, and the tic-tac-toe frame 601 is composed of two fixed plates and two cylindrical rods penetrating the fixed plates. One of the cylindrical rods 601 is rotatably connected to the discharge frame 4, and the other cylindrical rod of the well-shaped frame 601 slides through the arc groove 401 on the surface of the discharge frame 4, and one end of the cylindrical rod sliding through the arc groove 401 is connected to the head of the telescopic arm 305. The two cylindrical rods of the well-shaped frame 601 are respectively sleeved with a round-headed rod 603 and a square-headed rod 605, and the round-headed rod 603 is symmetrically distributed on both sides of the square-headed rod 605. The surface of the square-headed rod 605 is provided with a strip-shaped opening that slides with the cylindrical rod; two groups of cams 509 are symmetrically distributed on the U-shaped rod 506;

[0040] The cutting table 1 is provided with a clamping mechanism 5 for limiting the door and window profiles. The clamping mechanism 5 includes a cylinder b501 installed on the side of the cutting table 1. A rack 502 and a toothed disc 503 that mesh with each other are provided on the inner side of the cutting table 1. The rack 502 is connected to the output end of the cylinder b501. A transverse clamping seat 504 is provided on the upper side of the toothed disc 503. Connecting seats 508 are symmetrically installed on the upper surface of the cutting table 1 close to the guide wheel 2 and the upper surface of the discharge frame 4. A cam 509 is provided between two adjacent connecting seats 508. A U-shaped rod 506 is inserted in the middle of the cam 509. A longitudinal extrusion block 512 is provided on the outer side of the cam 509.

[0041] The surface of the toothed disc 503 is provided with two eccentric cavities eccentric to the center of the toothed disc 503, a push-pull rod sliding with the eccentric cavity is provided at the bottom of the horizontal clamping seat 504, a support plate 505 is vertically installed on the top of the rack 502, a cutting notch for the circular saw 3 blade to move is provided in the middle of the surface of the cutting table 1, and reserved grooves for the support plate 505 and the push-pull rod to slide linearly are provided on both sides of the cutting notch near the cutting notch, when the control cylinder b501 pushes the rack 502 forward to engage with the toothed disc 503, the toothed disc 503 is rotated to squeeze and push the two horizontal clamping seats 504 through the eccentric cavity on the surface to horizontally clamp the side of the metal door and window profile material;

[0042] The top of the support plate 505 is welded to one side of the U-shaped rod 506, and protrusions 507 are provided on both sides of the U-shaped rod 506. The inner wall of the cam 509 is provided with a spiral groove 510 that docks with the protrusion 507; an arc track 511 is provided in the middle of the outer side of the cam 509, and the arc track 511 is slidably connected to the longitudinal extrusion block 512, and a storage cavity is provided on the side of the cam 509 close to the arc track 511, and a return spring 513 is connected to the storage cavity, and one end of the return spring 513 is fixed to the longitudinal extrusion block 512, and the longitudinal The extrusion block 512 is in a crescent-shaped structure. When the cam 509 rotates, the longitudinal extrusion block 512 is driven closer to the upper side of the profile material. The longitudinal extrusion block 512 is set in a crescent-shaped structure, which facilitates the longitudinal extrusion block 512 with the crescent-shaped structure to gradually press against the upper side of the profile material. The outer arc surface of the arc track 511 and the rotation center of the cam 509 are coaxially arranged, so that when the longitudinal extrusion block 512 and the cam 509 rotate and slide relative to each other, the longitudinal extrusion block 512 can constantly and evenly press against the upper side of the profile material.

[0043] In specific implementation, the metal door and window profile material is conveyed to the direction of the circular saw 3 through the feeding roller 7 on one side of the cutting table 1, and is guided to prevent deviation under the action of the guide wheel 2. When the metal door and window profile material determines the cutting position, the feeding roller 7 is controlled to stop running and the cylinder b501 is controlled to push the rack 502 and the toothed disc 503 in a positive direction to engage, so that the toothed disc 503 pushes the push-pull rod at the bottom of the horizontal clamping seat 504 through the eccentric cavity on the surface when rotating, so that the two push-pull rods drive the horizontal clamping seat 504 to move closer to each other along the reserved groove on the cutting table 1 and clamp the side of the metal door and window profile material laterally;

[0044] At the same time, when the rack 502 moves forward, it drives the U-shaped rod 506 to move linearly along the connecting seat 508 through the top vertical support plate 505, and the U-shaped rod 506 squeezes the spiral groove 510 on the inner wall of the cam 509 through the protrusions 507 on both sides, so that the cam 509 rotates around the U-shaped rod 506. When the cam 509 rotates, it drives the longitudinal extrusion block 512 with a crescent-shaped structure on the outer side to press against the upper side of the metal door and window profile material. When the U-shaped rod 506 continues to squeeze the spiral groove on the inner wall of the cam 509 through the protrusions 507, When the cam 509 is rotated to 510, the cam 509 will continue to rotate but will not cause the longitudinal extrusion block 512 to flip. At this time, the longitudinal extrusion block 512 will rotate and slide with the arc track 511 outside the cam 509, so that the longitudinal extrusion block 512 and the cam 509 will slide relative to each other and stretch the return spring 513. Then, the longitudinal extrusion block 512 will elastically squeeze the upper side of the profile material when rotating, ensuring that the cam 509 will not cause deformation or damage to the upper side of the profile material through the extrusion and clamping of the longitudinal extrusion block 512 during the process of rotating into place;

[0045] The two groups of cams 509 are symmetrically arranged on the U-shaped rod 506. When the U-shaped rod 506 moves in the positive direction, the two groups of cams 509 are driven to rotate relative to each other. Therefore, the two groups of longitudinal extrusion blocks 512 are rotated and extruded away from each other when they are pressed against the two positions on the upper side of the profile material. Then, the metal door and window profile material can be positioned and clamped on the cutting table 1 by the two groups of cams 509 and longitudinal extrusion blocks 512 rotating in opposite directions, so as to prevent the metal door and window profile material from being lateral offset when being longitudinally clamped.

[0046] On the contrary, when the cylinder b501 is started to drive the rack 502 to move in the opposite direction to engage with the toothed disc 503 in the opposite direction, the two transverse clamping seats 504 will move away from each other and disengage from the clamping of the side of the metal door and window profile material. At the same time, the rack 502 will also drive the U-shaped rod 506 to move in the opposite direction to drive the longitudinal extrusion block 512 on the outside of the cam 509 away from the upper side of the metal door and window profile material, making it convenient for the feeding roller 7 to transport and feed the profile material.

[0047] See also Figure 1 , Figure 3-Figure 6 A crossbar is provided between the discharge frame 4 and the cutting opening, and a roller 101 is provided on the crossbar. Both ends of the roller 101 are movably connected to a cylinder a102 installed on the inner side of the cutting table 1. A proximity switch 103 is installed on the lower surface of the cutting table 1 near the cutting opening, and the proximity switch 103 is used to sense the blade of the circular saw 3 inserted into the cutting opening.

[0048] In specific implementation, when the circular saw 3 does not cut or sever the metal door and window profile material, the proximity switch 103 cannot sense the approach of the blade, so the cylinder a102 will continue to support the roller 101 on the cross arm to ensure that the roller 101 can support the bottom of the profile to be cut; when the circular saw 3 is operated to rotate and press down around the hinge seat 301, the circular saw 3 will cut the metal door and window profile material above the cutting opening through the rotating blade. When the blade of the circular saw 3 moves into the cutting opening and completes the cutting of the metal door and window profile material, the proximity switch 103 on the lower side of the cutting table 1 will sense the approach of the blade, so that the proximity switch 103 transmits a signal. A PLC controller is connected to the equipment, and the cylinder a102 is driven by the PLC controller to drive the roller 101 on the cross arm to move downward. When the waste profile produced after cutting is not supported by the roller 101, the upper side of the waste profile will still be squeezed by the longitudinal extrusion block 512. Therefore, the elastic reset action of the reset spring 513 can pull the longitudinal extrusion block 512 to rotate and slide in the opposite direction along the arc track 511, so that the reset rotating longitudinal extrusion block 512 will push the waste profile away from the blade of the circular saw 3, making it convenient to neatly drop the cut waste profile into the receiving mechanism 6 between the discharge frame 4, and there is no need to use other tools to clean the waste.

[0049] See also Figure 1-Figure 5 , Fig.11 and Fig.12 , an adjusting groove 402 is provided on the inner wall surface of the discharging frame 4 near the arc groove 401, and the depth of the upper end of the adjusting groove 402 is greater than the depth of the lower end of the adjusting groove 402, and the axis line of the arc groove 401, the axis line of the adjusting groove 402 and the rotation axis line of the well-shaped frame 601 coincide with each other; steel balls 602 are symmetrically arranged on the two cylindrical rods of the well-shaped frame 601, and inner cavities 604 docking with the steel balls 602 are provided in the middle of both ends of the round head rod 603, and the extension part of the inner cavity 604 to the two side surfaces of the round head rod 603 is set as a trumpet-shaped opening structure, and the round head rod 603 cooperates with the cylindrical rod of the well-shaped frame 601 through the trumpet-shaped openings on both sides of the inner cavity 604 when rotating, so that the round head rod 603 can easily limit the rotation angle through the trumpet-shaped opening when rotating;

[0050] The two side surfaces of the square rod 605 are symmetrically provided with traction bars 606 movably connected to the round rod 603. The side of the round rod 603 away from the square rod 605 is movably connected with a ball support pin 607, and the end of the ball support pin 607 away from the round rod 603 is slidably connected in the adjustment groove 402. The upper surfaces of the round rod 603 and the square rod 605 are movably connected with rollers, and the rollers on the round rod 603 and the square rod 605 can assist in conveying the raw materials.

[0051] A spring extrusion piece 608 is sleeved on the outer side of the ball head support pin 607. The spring extrusion piece 608 is composed of a conical spring and a washer. One end of the conical spring of the spring extrusion piece 608 is in contact with the ball head support pin 607, and the other end of the conical spring is in contact with the washer. The ends of the round head rod 603 and the square head rod 605 close to the cutting opening are both connected with a rubber block 609. When the round head rod 603 and the square head rod 605 are flipped back and forth, they can be squeezed and contacted with the cross arm through the elastic action of the rubber block 609.

[0052] In specific implementation, when the circular saw 3 is operated to flip around the articulated seat 301 to cut the raw material, the rotating shaft in the middle of the articulated seat 301 will drive the balance wheel 302 to squeeze the connecting rod 303 downward, so that the connecting rod 303 will drive the telescopic arm 305 at the bottom to move downward along the slide rail seat 304. At this time, the head of the telescopic arm 305 will drive one of the cylindrical rods of the well-shaped frame 601 to slide along the arc groove 401 on the surface of the discharge frame 4, and the other cylindrical rod of the well-shaped frame 601 will flip around the discharge frame 4, so that the well-shaped frame 601 drives the rubber block 609 of the round head rod 603 and the square head rod 605 to flip and move downward. When the cylindrical rod of the well-shaped frame 601 slides up and down along the arc groove 401 on the surface of the discharge frame 4, the telescopic characteristics of the telescopic arm 305 can adapt to the lateral displacement deviation caused by the cylindrical rod sliding up and down along the arc groove 401.

[0053] Since the depth of the upper end of the adjustment groove 402 is greater than the depth of the lower end of the adjustment groove 402, when the two groups of round-headed rods 603 on the tic-tac-toe frame 601 are flipped downward, the ball head support pin 607 on the side of the round-headed rod 603 will move downward from the upper end of the adjustment groove 402, and the ball head support pin 607 abuts against the washer through the conical spring sleeved on the outside, so that when the ball head support pin 607 rotates downward, the conical spring squeezes the washer to drive the ball head support pin 607 to squeeze the side of the round headed rod 603, so that the round headed rod 603 rotates around the steel ball 602 on the cylindrical rod through the inner cavity 604. When the two groups of round-headed rods 603 deflect toward the direction of the square-headed rods 605, the round-headed rods 603 will squeeze the square-headed rods 605 through the traction strips 606 on the side, so that the square-headed rods 605 will move down along the cylindrical rods of the well-shaped frame 601 through the strip-shaped openings on the surface. When the round-headed rods 603 at the two sides deflect laterally toward the direction of the square-headed rods 605, the square-headed rods 605 at the middle position move downward, so that the round-headed rods 603 and the square-headed rods 605 form an inclined concave material guide ramp, so that the waste of the profiles that have been cut can be quickly gathered and collected along the receiving mechanism 6 and the discharging frame 4.

[0054] On the contrary, when the circular saw 3 is operated to rotate in the opposite direction around the articulated seat 301 away from the cutting edge of the cutting table 1, the swing wheel 302 on the side of the articulated seat 301 will pull the connecting rod 303 to drive the telescopic arm 305 to move upward, thereby driving the criss-cross frame 601 to rotate in the opposite direction and move upward in the discharge frame 4, ensuring that the round-headed rod 603 and the square-headed rod 605 are flipped to a horizontal position, so that the cutting device can transport and export raw materials with the assistance of the round-headed rod 603 and the square-headed rod 605 when not cutting metal door and window profiles.

[0055] See also Figure 1 , Figure 2 and Fig.13 A bottom box 8 is arranged on the lower side of the cutting table 1 away from the circular saw 3, and a ramp for collecting waste chips is arranged on the side of the bottom box 8 close to the discharge frame 4. A waste conveyor 9 is arranged transversely inside the bottom box 8. When the circular saw 3 is operated to cut the metal door and window profile raw material into a standard length on the cutting table 1, the waste generated by the cutting enters the bottom box 8 along the receiving mechanism 6 between the discharge frame 4, and the waste slag and chips generated by the cutting will also enter the bottom box 8 along the ramp, and then be discharged by the waste conveyor 9 inside the bottom box 8. By placing a receiving tray of suitable size under the outlet side of the waste conveyor 9, the recycling of metal door and window profile waste can be conveniently carried out.

[0056] To summarize, the metal door and window profile raw material is conveyed toward the circular saw 3 by the feeding roller 7 on one side of the cutting table 1, and is guided to prevent deviation under the action of the guide wheel 2. When the metal door and window profile raw material determines the cutting position, the transverse clamping seat 504 and the longitudinal extrusion block 512 of the clamping mechanism 5 can synchronously press against the side and upper side of the metal door and window profile raw material. When the circular saw 3 is rotated and pressed down around the hinge seat 301, the circular saw 3 will cut the metal door and window profile raw material according to the predetermined specifications and dimensions through the rotating blade. The contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
