Description

Technical Field

[0001] The invention relates to the technical field of metal cutting, and in particular to a metal cutting device used for manufacturing doors and windows. Background Art

[0002] Aluminum profiles are usually used to splice the external frames of doors and windows in the manufacturing of doors and windows. Aluminum profiles refer to straight strips of metal aluminum with a certain cross-sectional shape and size after plastic processing. During production, long strips of aluminum profiles will be cut into long strips of equal length and packaged before being shipped out of the factory for customers to use cutting devices to cut them into suitable sizes for door and window manufacturing.

[0003] Commonly used cutting devices use a cutting machine to cut the aluminum profile perpendicular to it, so that the aluminum profile forms a flat cross-section. In actual manufacturing and installation, in order to improve the connection strength and aesthetics, the connection between two mutually perpendicular aluminum profiles is generally cut at a 45-degree angle, and the two angled cuts are spliced ​​by hardware. However, the existing production line is not convenient for directly cutting the bevel. It is necessary to manually adjust the angle of the aluminum profile and then cooperate with the cutting device for cutting, or manually operate the cutting device for cutting. These two methods require frequent adjustment of the fixing device and position of the aluminum profile, and the manual cutting method is prone to angle deviation, making the finished doors and windows difficult to match and requiring secondary cutting, which affects production efficiency and aesthetics, and also causes waste of aluminum profiles.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention provides a limiting mechanism, which adjusts the position of the electric slide block by a preset length, thereby controlling the length between the end of the aluminum profile and the rotating disc cutter, thereby facilitating cutting out the required length.

[0020] The present invention provides an adjustment mechanism, which can align and clamp aluminum profiles of different sizes with the center of the material table by adjusting the distance between the friction wheels on both sides of the material table, and simultaneously use the friction wheels to convey the aluminum profile. The centered aluminum profile is parallel to the material table, which can effectively improve the cutting accuracy of the aluminum profile and prevent the subsequent cutting from being offset due to conveying, which ultimately makes it impossible to splice the two sections of aluminum profile normally and requires temporary adjustment and cutting.

[0021] The present invention provides a steering mechanism. The steering mechanism locks or unlocks the turntable by rotating a steering rod to push the movable column and the arc block to move forward and backward along the installation groove, and can push the wedge-shaped slider to move up and down to adjust the angle between the turntable and the annular fixed table. The three matching grooves can be used to simply, effectively and quickly adjust the angle between the turntable and the rotating disc cutter and the aluminum profile, so as to facilitate cutting of the aluminum profile with a forty-five degree cross-section. The steering rod can be manually rotated using an external tool or driven by an external electric tool. Both methods have the advantages of being convenient and fast, and can be flexibly set according to the production site environment. The steering mechanism is used in conjunction with the matching groove and the clamping block, so that the cutting angle of the rotating disc cutter can be conveniently and quickly adjusted without measuring the angle. The operation is convenient and efficient.

[0022] The present invention provides guide grooves and rotating disc cutters. When the rotating disc cutters are cutting, the grinding disc can grind the cross section of the aluminum profile synchronously, which can effectively remove the burrs of the cross section and facilitate the subsequent splicing, thereby reducing the operation steps and time of door and window manufacturing. The three guide grooves cooperate with the direction adjustment of the steering mechanism, so that the rotating disc cutters can cut the aluminum profile into a cross section with an angle of 45 degrees, which is convenient for subsequent two-by-two connection without the need for additional on-site cutting, and can also reduce the waste of aluminum profiles. In addition, doors and windows of other shapes and angles may also appear in production. At this time, the angle of the cross section at the connection is not completely 45 degrees. At this time, the structure in the middle of the material table can be replaced with guide grooves of other angles, or directly replaced with an open structure. In combination with the steering mechanism that can adjust the angle at will, the cutting of cross sections of other angles can be achieved. The present invention has strong adaptability and does not need to frequently measure and adjust the angle of the aluminum profile like a traditional cutting device. Compared with the traditional manually operated cutting device, the method of the present invention has a high degree of automation. The rotating disc cutter does not need manual operation during the rotation operation, which can reduce the damage of the rotating machinery to personnel. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] Reference Figure 1-14A metal cutting device for door and window manufacturing, comprising a first operating table 1 and a rotating disc knife 35, a second operating table 101 is arranged on one side of the first operating table 1, a material table 2 is installed on the top of the first operating table 1 and the second operating table 101, an aluminum profile 3 is placed on the top of the material table 2, a fixed round table 19 is arranged between the first operating table 1 and the second operating table 101, a rotating disc knife 35 is arranged above the fixed round table 19, grinding discs 36 are installed on the side walls of the rotating disc knife 35, a limiting mechanism 6 is arranged on the top of the material table 2 above the second operating table 101, two fixed slides 11 are symmetrically arranged on the top of the first operating table 1, an adjusting mechanism 13 is arranged on the fixed slide 11, an annular fixed table 20 is fixedly connected to the top of the fixed round table 19, a turntable 23 is rotatably connected to the annular fixed table 20, a mounting groove is opened at the bottom of the turntable 23, a steering mechanism 24 is arranged in the mounting groove, and a support plate 30 is fixedly connected to the top of the turntable 23;

[0040] The adjusting mechanism 13 includes an adjusting slider 12 and a rotating shaft 14. Slide grooves 111 are provided on both sides of the top of the fixed slide 11. The adjusting slider 12 is slidably connected in the slide grooves 111. The top of the adjusting slider 12 is rotatably connected to a friction wheel 18. Two bearing seats 112 are symmetrically arranged at the top of the fixed slide 11. The tops of the two bearing seats 112 are rotatably connected to a rotating shaft 14.

[0041] The steering mechanism 24 includes a steering rod 25 and a wedge-shaped slider 28. A movable column 26 is slidably connected in the mounting groove. An arc block 261 is fixedly connected to the side wall of one end of the movable column 26. A steering rod 25 is threadedly connected to the other side of the movable column 26. A vertically sliding wedge-shaped slider 28 is slidably connected to the top of the mounting groove. The aluminum profiles 3 used in the manufacture of doors and windows are generally cut by a rotating disc cutter 35 dedicated to aluminum. A large number of aluminum profile 3 frames are required in the batch manufacturing of doors and windows. In order to improve the operating efficiency and cutting accuracy of the aluminum profile 3 cutting, automated equipment is used for operation. The material table 2 is used to place and convey continuous large-length prototype aluminum profiles 3 through the action of the friction wheel 18. During the conveying process, the limit mechanism 6 adjusts the position of the electric slider 9 by a preset length, so as to control the length between the end of the aluminum profile 3 and the rotating disc cutter 35, so as to facilitate cutting out the required length. While the rotating disc cutter 35 is cutting, the grinding disc 36 can simultaneously grind the cross section of the aluminum profile 3, which can effectively remove the burrs on the cross section and facilitate the later splicing, thereby reducing the operating steps and time of door and window manufacturing. In actual production, the sizes of the aluminum profiles 3 used are different according to the different sizes of doors and windows customized by customers. The adjustment mechanism 13 can adjust the distance between the friction wheels 18 on both sides of the material table 2. Aluminum profiles 3 of different sizes are aligned with the center of the material table 2, and the friction wheel 18 is used to convey the aluminum profile 3 simultaneously. The centered aluminum profile 3 is parallel to the material table 2, which can effectively improve the cutting accuracy of the aluminum profile 3 and prevent the subsequent cutting from being offset due to the conveying, which eventually makes it impossible to splice the two sections of aluminum profile 3 normally and requires temporary adjustment and cutting. The steering mechanism 24 locks or unlocks the turntable 23 by rotating the steering rod 25 to push the movable column 26 and the arc block 261 to move forward and backward along the installation groove, and can push the wedge-shaped slider 28 to move up and down to realize the angle between the turntable 23 and the annular fixed table 20. The angle between the turntable 23 and the rotating disc knife 35 and the aluminum profile 3 can be simply, effectively and quickly adjusted to facilitate cutting of aluminum profiles 3 with a forty-five degree cross-section. The steering rod 25 can be manually rotated using an external tool or driven by an external electric tool. Both methods have the advantages of convenience and speed, and can be flexibly set according to the production site environment.

[0042] As a technical optimization scheme of the present invention, three guide grooves 201 are provided in the middle of the material platform 2, and the angles between the three guide grooves 201 are all 45 degrees. The part of the material platform 2 with the guide grooves 201 is connected to the main body of the material platform 2 by bolts. The three guide grooves 201 cooperate with the direction adjustment of the steering mechanism 24, so that the rotating disc knife 35 can cut the aluminum profile 3 into a section with a 45-degree angle, which is convenient for subsequent two-by-two connection without the need for additional on-site cutting, and can also reduce the waste of aluminum profile 3. In addition, doors and windows of other shapes and angles may appear in production, and the angle of the section at the connection is not completely 45 degrees. At this time, the structure in the middle of the material platform 2 can be replaced with guide grooves 201 of other angles, or directly replaced with an open structure, and with the steering mechanism 24 that can adjust the angle arbitrarily, it can achieve cutting of sections of other angles, with strong adaptability, and no need to frequently measure and adjust the angle of the aluminum profile 3 like traditional cutting devices.

[0043] As a technical optimization scheme of the present invention, a connecting frame 4 is fixedly connected to the side wall of the middle part of the material platform 2, and an electric telescopic rod 5 is fixedly installed on the side wall of the connecting frame 4. Two telescopic ends are arranged at the bottom of the electric telescopic rod 5, and triangular fixed blocks 501 are fixedly installed at the ends of the two telescopic ends. A rubber sheet 502 is installed at the bottom of the fixed block 501, and the fixed block 501 is located directly above the material platform 2. After the aluminum profile 3 transported to the right place by the friction wheel 18 stops being transported, the telescopic end of the electric telescopic rod 5 is controlled to extend, and finally the rubber sheet 502 abuts against the top of the aluminum profile 3. The rubber sheet 502 can enhance the friction force to prevent the aluminum profile 3 from sliding and deviating during the cutting process. The two fixed blocks 501 are adapted to the positions of the three guide grooves 201, and the normal advancement and cutting of the rotating disc knife 35 is not hindered while pressing the aluminum profile 3. After the cutting is completed, when the rotating disc knife 35 retreats to the right place, the telescopic end of the electric telescopic rod 5 is controlled to contract, and the aluminum profile 3 can continue to be transported through the friction wheel 18.

[0044] As a technical optimization scheme of the present invention, the limiting mechanism 6 includes a fixed frame 7 and a pneumatic telescopic rod 10. Two fixed frames 7 are symmetrically installed on both sides of the top of the material table 2 above the second operating table 101. Two guide rods 8 are fixedly installed on the top of the two fixed frames 7. An electric slider 9 is slidably connected to the two guide rods 8. The pneumatic telescopic rod 10 is installed on the electric slider 9. The telescopic end of the pneumatic telescopic rod 10 passes through the electric slider 9. The size of each batch of doors and windows is calculated according to the preset value, and the electric slider 9 is controlled to slide along the guide rod 8 to the preset value and stop, and the telescopic end of the pneumatic telescopic rod 10 is controlled to extend. At this time, when the friction wheel 18 conveys the end of the aluminum profile 3 to the telescopic end of the pneumatic telescopic rod 10, the second motor 17 is triggered to stop working, so that the cutting length of the aluminum profile 3 can be effectively adjusted. When the cutting is completed, the telescopic end of the pneumatic telescopic rod 10 is retracted, and the aluminum profile 3 can continue to be conveyed.

[0045] As a technical optimization solution of the present invention, two-way threads 141 are provided at both ends of the rotating shaft 14. The rotating shaft 14 is threadedly connected to the two adjusting sliders 12 through the two-way threads 141 at both ends. The centers of the two rotating shafts 14 above the first operating platform 1 are connected through the first chain 15. A first motor is fixedly installed on the top of the first operating platform 1, and the output end of the first motor is connected to the first chain 15 through a gear. When conveying the aluminum profile 3, the two rotating shafts 14 can be driven to rotate synchronously by first controlling the first motor to rotate forward and reversely to drive the first chain 15. At this time, the two-way threads 141 on both sides of the two rotating shafts 14 can drive the two adjusting sliders 12 and the friction wheel 18 to slide along the slide groove 111 in opposite directions or opposite directions until the friction wheel 18 abuts against the two side walls of the aluminum profile 3. At this time, the first motor can be stopped to complete the centering and clamping operations of the aluminum profile 3.

[0046] As a technical optimization solution of the present invention, a connecting beam 16 is fixedly connected between two opposite adjusting sliders 12 on two fixed slides 11 at the top of the first operating table 1, a second motor 17 is fixedly installed at the top of the connecting beam 16, and the friction wheels 18 at both ends of the connecting beam 16 are connected by a second chain 171, and the output end of the second motor 17 is connected to the second chain 171 through a gear. After the aluminum profile 3 is centered, the second motor 17 is controlled to start and drive the second chain 171 to rotate and drive the friction wheels 18 at both ends to rotate synchronously, so that the aluminum profile 3 can be conveyed and moved by friction force, and the setting of the connecting beam 16 can make the second motor 17 move synchronously with the movement of the adjusting slider 12 when the adjusting mechanism 13 is working, without affecting the subsequent conveying of the aluminum profile 3.

[0047] As a technical optimization solution of the present invention, three matching grooves 21 are evenly opened on the middle side wall of the annular fixing platform 20, and the angle between the three matching grooves 21 with the center of the annular fixing platform 20 as the center is 45 degrees. An annular groove 22 is opened on the inner wall of the top of the annular fixing platform 20, and three clamping blocks 221 are evenly arranged in the annular groove 22. The three clamping blocks 221 correspond to the three matching grooves 21 and are misaligned. The three matching grooves 21 are used for cutting aluminum profiles 3 with a cross-section of 45 degrees. The cutting angle can be easily adjusted to the desired position by presetting the position in advance without unnecessary operation to adjust the aluminum profile 3 or adjust the rotating disc knife 35. The angle can be adjusted by turning the steering rod 25 to push the arc block 261 into the matching groove 21.

[0048] As a technical optimization solution of the present invention, the end of the steering rod 25 passes through the turntable 23, and the end of the steering rod 25 is rotatably connected to the turntable 23. The top of the movable column 26 is fixedly connected to a trapezoidal block 27. The inclined end of the trapezoidal block 27 is adapted to the inclined end of the wedge-shaped slider 28. A tension spring 29 is fixedly connected between the bottom end of the sliding rod on both sides of the wedge-shaped slider 28 and the mounting groove. When adjusting the cutting angle, firstly, the steering rod 25 is reversely rotated to drive the movable column 26 to move outward along the installation groove, so that the arc block 261 is separated from the matching groove 21, and the steering rod 25 is further reversed, and the movable column 26 continues to move until the inclined surface end of the trapezoidal block 27 contacts the wedge-shaped slider 28. At this time, under the pull of the tension spring 29, the wedge-shaped slider 28 can slide down along the installation groove until the top of the wedge-shaped slider 28 is separated from the block 221. At this time, the turntable 23 can be unlocked, and the turntable 23 is rotated to drive the rotating disc knife 35 to rotate. The counterclockwise or clockwise rotation makes the angle between the rotating disc knife 35 and the aluminum profile 3 be 45 degrees (or 135 degrees). ), at this time, the steering rod 25 can be turned forward to drive the movable column 26 to move inward along the installation groove until the inclined end of the trapezoidal block 27 contacts the inclined end of the wedge-shaped slider 28, and the wedge-shaped slider 28 is pushed to rise along the installation groove. At this time, the turntable 23 is continued to be rotated until the wedge-shaped slider 28 abuts the block 221 to determine that the angle of the turntable 23 is adjusted in place. At this time, the steering rod 25 is continued to be turned forward to make the arc block 261 enter the matching groove 21 to lock the turntable 23. The steering mechanism 24 is used in conjunction with the matching groove 21 and the block 221, so that the cutting angle of the rotating disc knife 35 can be conveniently and quickly adjusted without measuring the angle, which is convenient to operate and efficient.

[0049] As a technical optimization scheme of the present invention, two fixed slide rails 32 are fixedly installed on the top of the support plate 30, and a mounting plate 33 is slidably connected to the top of the two fixed slide rails 32. A third motor 31 is fixedly installed on the side wall of the support plate 30, and a screw is fixedly connected to the output end of the third motor 31. The screw is threadedly connected to the bottom of the mounting plate 33, and a fourth motor 34 is fixedly installed on one side of the top of the mounting plate 33. The rotating disc knife 35 is fixedly installed on the output shaft of the fourth motor 34. A protective bin 351 is fixedly installed on the other side of the top of the mounting plate 33, and a waste hopper 352 is fixedly connected to the bottom of the protective bin 351. After the limiting mechanism 6 positions the cutting length of the aluminum profile 3, the fourth motor 34 is started to drive the rotating disc knife 35 to rotate, and then the third motor 31 is started to drive the screw to rotate to push the mounting plate 33 to slide along the fixed slide rail 32. As the mounting plate 33 slides, the rotating disc knife 35 can cut the aluminum profile 3. During the cutting process, the cutting waste can fall into the protective bin 351 and be released to the outside through the waste hopper 352. After the cutting is completed, the third motor 31 is reversed to reset the rotating disc knife 35. After resetting, the fourth motor 34 is stopped. During the cutting and resetting process, the grinding disc 36 can grind the cross-section of the aluminum profile 3 to facilitate the removal of burrs. Compared with the traditional manually operated cutting device, the method of the present invention has a high degree of automation. The rotating disc knife 35 does not require manual operation during the rotation operation, which can reduce the harm of the rotating machinery to personnel.

[0050] As a technical optimization solution of the present invention, the top of the second operating table 101 is provided with parts including an adjustment mechanism 13 having the same structure as the top of the first operating table 1, which is used to convey the cut aluminum profile 3. The friction wheel 18 and the adjustment mechanism 13 on the second operating table 101 have the same functions and usages as those on the first operating table 1, and are mainly used to convey the cut aluminum profile 3, and can work synchronously with the first operating table 1, or can be used separately according to usage requirements.

[0051] When the present invention is in use, when conveying the aluminum profile 3, firstly, by controlling the first motor to rotate forward and reversely to drive the first chain 15 to rotate, the two rotating shafts 14 can be driven to rotate synchronously. At this time, the two-way threads 141 on both sides of the two rotating shafts 14 can drive the two adjusting sliders 12 and the friction wheels 18 to slide along the slide groove 111 toward or away from each other until the friction wheels 18 abut against the two side walls of the aluminum profile 3. At this time, the first motor can be stopped to complete the centering and clamping operations of the aluminum profile 3. The second motor 17 is controlled to start and drive the second chain 171 to rotate to drive the friction wheels 18 at both ends to rotate synchronously, so that the aluminum profile 3 can be conveyed and moved by friction force. When the aluminum profile 3 is transmitted to the material table 2 above the second operating table 101, the electric slider 9 is controlled to slide along the guide rod 8 to the preset value and stop, and the telescopic end of the pneumatic telescopic rod 10 is controlled to extend. At this time, when the end of the aluminum profile 3 conveyed by the friction wheel 18 reaches the telescopic end of the pneumatic telescopic rod 10 The second motor 17 is triggered to stop working. After the aluminum profile 3 transported to the position by the friction wheel 18 stops being transported, the telescopic end of the electric telescopic rod 5 is controlled to extend, and finally the rubber sheet 502 abuts against the top of the aluminum profile 3. The rubber sheet 502 can enhance the friction force. The fourth motor 34 is started to drive the rotating disc knife 35 to rotate. The third motor 31 is then started to drive the screw to rotate to push the mounting plate 33 to slide along the fixed slide rail 32. As the mounting plate 33 slides, the rotating disc knife 35 can cut the aluminum profile 3. During the cutting process, the cutting waste can fall into the protection bin 351 and be released to the outside through the waste hopper 352. After the cutting is completed, the third motor 31 is reversed to reset the rotating disc knife 35. After resetting, the fourth motor 34 is stopped. During the cutting and resetting process, the grinding disc 36 can grind the cross section of the aluminum profile 3. The cut aluminum profile 3 is transported out through the friction wheel 18 on the second operating table 101.

[0052] When the cutting section angle needs to be adjusted, first, the steering rod 25 is reversed to drive the movable column 26 to move outward along the installation groove, so that the arc block 261 is separated from the matching groove 21, and the steering rod 25 is further reversed. The movable column 26 continues to move until the inclined surface end of the trapezoidal block 27 contacts the wedge-shaped slider 28. At this time, under the pull of the tension spring 29, the wedge-shaped slider 28 can slide down along the installation groove until the top of the wedge-shaped slider 28 is separated from the block 221. At this time, the turntable 23 can be unlocked, and the rotating disc knife 35 is driven to rotate by rotating the turntable 23. The rotating disc knife 35 is rotated counterclockwise or clockwise to make the rotating disc knife 35 The included angle with the aluminum profile 3 is forty-five degrees (or one hundred and thirty-five degrees). At this time, the steering rod 25 can be rotated forward to drive the movable column 26 to move inward along the installation groove until the inclined end of the trapezoidal block 27 contacts the inclined end of the wedge-shaped slider 28, pushing the wedge-shaped slider 28 to rise along the installation groove. At this time, the turntable 23 can be continued to be rotated until the wedge-shaped slider 28 abuts the block 221 to determine that the angle of the turntable 23 is adjusted to the right position. At this time, the steering rod 25 can be continued to be rotated forward so that the arc block 261 is connected to the matching groove 21 to lock the turntable 23. At this time, the above operation can be repeated to cut out the aluminum profile 3 with a beveled section.
