Description

Technical Field

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

[0002] Metal doors and windows are doors and windows with metal materials as the main frame and structure. They are widely used in the construction field. When processing metal doors and windows, it is often necessary to cut the profiles. Laser cutting uses a high-energy-density laser beam to irradiate the metal profile, causing the material to melt or vaporize instantly, thereby achieving the purpose of cutting.

[0003] In the manufacturing process of metal doors and windows, profile cutting is a crucial process. Generally speaking, the profile to be cut must be placed steadily on the cutting table first. After the limit operation is completed, the cutting operation can be carried out. However, when it comes to some thinner profiles, especially the cutting of aluminum profiles, there are unique challenges. Aluminum, as a common metal material, has excellent thermal conductivity. During the cutting process, the cutting area will generate a lot of heat due to the friction between the cutting tool and the profile. Due to the excellent thermal conductivity of aluminum, this heat will quickly transfer to the surrounding non-cutting area. This rapid heat conduction causes a significant temperature gradient to form between the cutting area and the non-cutting area. For example, during actual cutting, The temperature of the cutting area may soar to hundreds of degrees in an instant, while the temperature of the adjacent non-cutting area is only tens of degrees. Such a huge temperature difference leads to a complex thermal stress distribution inside the material. When this thermal stress exceeds the yield strength of the aluminum profile itself, it will cause the aluminum profile to deform. This deformation not only affects the dimensional accuracy of the aluminum profile, making it difficult to meet the strict requirements of door and window assembly, but may also reduce the mechanical properties of the aluminum profile, affecting the overall quality and service life of the doors and windows. The deformed aluminum profile may have problems such as loose splicing and poor sealing performance during the subsequent processing and installation process, which in turn affects the overall performance and aesthetics of the metal doors and windows. For this reason, we propose a cutting device for metal door and window processing. Summary of the Invention

[0021] 2. Auxiliary fixing effect: When the fourth magnet moves down to the outer wall of the profile, the pressure it exerts on the profile can serve as an additional fixing method, cooperating with the attraction of the third magnet to further enhance the fixing effect on the profile.

[0022] 3. Improve support stability: When the fourth magnet moves downward, the sixth magnet moves downward synchronously, and then the movable vertical bar with a downward pressing slope is used to press down the pressing block, so that the end of the side displacement block pushes the push plate up and down to maintain the stability of the pressing position of the third magnet. Through the chain reaction of multiple components, the pressing position of the third magnet is ensured to be stable and not easy to move downward, thereby ensuring the stability and normal operation of the entire pressing support.

[0023] 4. Reduce maintenance costs: The relatively simple and closely coordinated magnetic mechanical structure reduces the need for complex drive devices and frequent manual intervention, saving maintenance time and costs.

[0024] 5. When the profile moves, the magnetic limiters at the upper and lower ends can limit the guide frame to a certain extent, reducing the occurrence of up and down movement of the guide frame so that the upper and lower guide wheels fit the inner wall of the profile.

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0044] Example 1: Please refer to Figures 1-10 As shown, the present invention provides a technical solution: a cutting device for processing metal doors and windows, including a cutting table 1, a laser cutting gun 2 is installed on the cutting table 1, the laser cutting gun 2 can be moved, specifically can be moved in the X direction and the Y direction, and can also be lifted and moved as needed. The moving structure in each direction is the existing technology and will not be described here. It also includes two internal support components 3, two magnetic limiters 5, two magnetic abutting components 6, abutting limiter component 7 and a lifting component 4. The two internal support components 3 are used to support the door and window profiles to be cut from the inside to reduce the occurrence of deformation during cutting. Each magnetic limiter 5 corresponds to an internal support component 3, and is used to make the internal support The support assembly 3 maintains the stability of the upper and lower positions. Each magnetic pressing assembly 6 corresponds to an internal support assembly 3, and each magnetic pressing assembly 6 includes two groups of third magnets 61 and fourth magnets 65 that are magnetically attracted to each other. The third magnet 61 is arranged on the internal support assembly 3. The magnetic pressing assembly 6 is used to press the upper and lower sides of the cutting point of the door and window profile to be cut from the inside during cutting, so as to reduce the occurrence of deformation at the cutting point during cutting. The pressing limit assembly 7 is used to limit the displacement of the magnetic pressing assembly 6 when the magnetic pressing assembly 6 is pressing. The lifting assembly 4 is connected to the fourth magnet 65, and the distance between the fourth magnet 65 and the third magnet 61 is adjusted by the lifting assembly 4 to change the magnetic attraction force.

[0045] Among them, see Figure 3-Figure 4 As shown, the internal support assembly 3 includes a guide frame 31 that can enter the door and window profile to be cut. Guide wheels 32 are installed on the upper and lower surfaces of the guide frame 31. The guide wheel 32 is rotatable, and the upper and lower ends of the guide frame 31 close to the cutting surface are fixed with protrusions 33. The outward end point of the protrusion 33 does not exceed the outermost end of the guide wheel 32. When moving the door and window profile to be cut, the guide wheel 32 can be used to move the profile outside the guide frame 31.

[0046] See Figure 9-10 As shown, the lifting assembly 4 includes a mounting plate 41 and a telescopic rod 42. The telescopic rod 42 is preferably a pneumatic telescopic rod or an electric telescopic rod. The mounting plate 41 is fixed to the convex plate on the rear side of the upper end surface of the cutting table 1. The telescopic rod 42 is vertically installed on the mounting plate 41. By starting the telescopic rod 42, the telescopic rod 42 can be used to drive the lifting and lowering of the structure connected to it.

[0047] See Figure 3-Figure 5 as well as Figure 9 As shown, the magnetic limiter 5 includes a first magnet 51 fixed to the upper and lower sides of the guide frame 31 and a second magnet 52 fixed to the lower end surface of the mounting plate 41. The first magnet 51 and the second magnet 52 magnetically repel each other, so that when the profile moves, the magnetic limiters 5 at the upper and lower ends can limit the guide frame 31 to a certain extent, reducing the occurrence of the up and down movement of the guide frame 31, so that the upper and lower guide wheels 32 fit the inner wall of the profile.

[0048] See Figure 5 As shown, the magnetic attraction and tightening component 6 also includes a connecting plate 62 and a connecting bar 64. The connecting plate 62 is connected to the inner wall of the third magnet 61. The end of the connecting plate 62 facing away from the third magnet 61 is fixed with a push plate 63, and one end of the connecting bar 64 is installed on the fourth magnet 65 through a magnetic isolation plate.

[0049] See Figure 6-Figure 8 As shown, limiting bars 67 are fixed on both sides of the third magnet 61, and vertical limiting grooves 66 are provided on both sides of the guide frame 31 and at one end of the protrusion 33. The limiting bars 67 slide in the limiting grooves 66. When the third magnet 61 moves up and down, the limiting bars 67 can accurately move linearly along the limiting grooves 66. This is because the limiting grooves 66 provide a predetermined movement trajectory for the limiting bars 67. Under this structural design, the linear movement of the limiting bars 67 can effectively constrain the third magnet 61, so that the third magnet 61 maintains a high degree of stability during the up and down movement, and avoids the misalignment phenomenon that may be caused by movement to a great extent, thereby ensuring the stable operation of the entire magnetic attraction and tightening component 6.

[0050] See Figures 6-10 As shown, the pressing limit assembly 7 includes a fifth magnet 71 and a sixth magnet 77 that repel each other magnetically. The sixth magnet 77 is installed on the bottom end of the telescopic rod 42 through a magnetic isolation plate. The bottom end of the fifth magnet 71 is connected to a movable vertical bar 72. A through-hole 311 is provided on the upper end surface of the guide frame 31. The movable vertical bar 72 passes through the through-hole 311, and the bottom end of the movable vertical bar 72 is connected to a downward pressure block 73. One side of the downward pressure block 73 is connected to a side displacement block 74, and the end of the downward pressure block 73 can be embedded between the two relative push plates 63. The movable vertical bar 72 moves downward to squeeze the downward pressure block 73, so that the side displacement block 74 pushes the two push plates 63. Among them, the upper end surface of the downward pressure block 73 is integrally formed with a downward extrusion slope, the bottom end of the movable vertical bar 72 is provided with a downward pressure slope that cooperates with the downward extrusion slope, and the upper and lower surfaces of the side displacement block 74 are provided with pushing slopes near the end. When the sixth magnet 77 moves downward, as it approaches the fifth magnet 71, the fifth magnet 71 is pressed to move the movable vertical bar 72 downward, thereby squeezing the downward pressure block 73 with the downward extrusion slope, and pushing the side displacement block 74 by the component force in the length direction of the side displacement block 74, the side displacement block 74 with the pushing slope can be extended between the two push plates 63 to press and restrict the fifth magnet 71.

[0051] In summary, when in use, when the aluminum profile is cut, the internal support component 3 is inserted deep into the profile. After the profile to be cut is moved to the cutting position, the lifting component 4 can be started, and the telescopic rod 42 can be used to drive the fourth magnet 65 to move downward. The fourth magnet 65 is close to the corresponding third magnet 61 to attract the third magnet 61 to move to the upper and lower surfaces inside the profile, thereby increasing the support effect at both ends of the cutting position, effectively dispersing the stress generated during the cutting process, making the stress evenly distributed on the supporting part of the profile, and reducing the occurrence of deformation at the cutting position. Among them, when the fourth magnet 65 moves down to the outer wall of the profile, the fourth magnet 65 not only has a magnetic attraction force with the third magnet 61, but also has the function of pressing and restricting the profile to be cut from the outside;

[0052] As the fourth magnet 65 gradually moves downward, the sixth magnet 77 moves downward in sync. Due to the repulsive magnetic relationship between the sixth magnet 77 and the fifth magnet 71, when the sixth magnet 77 moves downward, the fifth magnet 71, affected by the repulsive force, also moves downward. After the fifth magnet 71 moves downward, it acts on the movable vertical bar 72 with a downward-pressing inclined surface. As the fifth magnet 71 continues to press downward, the movable vertical bar 72, with its unique downward-pressing inclined surface structure, transmits force to the downward-pressing block 73, thereby pushing the downward-pressing block 73 to move. When the downward-pressing block 73 moves, the associated side-shifting block 74 also moves accordingly. During this movement, the end of the side-shifting block 74 pushes up and down, continuously pressing against the push plate 63. Under the pushing force of the end of the side-shifting block 74, the push plate 63 plays a key role in maintaining the stability of the pressing position of the third magnet 61, preventing it from moving downward, thereby ensuring the stability and normal operation of the entire pressure support.

[0053] See Figure 6-Figure 7 As shown, the bottom end of the pressing block 73 is connected to a guide block 75, and a transverse guide groove 76 is provided at the inner bottom of the guide frame 31. The guide block 75 slides in the guide groove 76, and a ball is installed inside the guide groove 76 to reduce friction. When the pressing block 73 moves laterally, the guide block 75 moves along the guide groove 76, which can guide the movement of the pressing block 73 and avoid skewing.

[0054] Example 2: Please refer to Figure 6 and Figure 11As shown, this embodiment is extended on the basis of embodiment 1: the cutting device for processing metal doors and windows also includes a push rod 10, one end of which is installed with a cross insert 9, and the opposite sides of the two guide frames 31 are provided with a cross insert 8, and the cross insert 9 is inserted and matched with the cross insert 8. When fine-tuning the position of the guide frame 31, the cross insert 9 at the end of the push rod 10 can be embedded in the cross insert 8, and then the push rod 10 can be used to apply force, which is more convenient.
