Description

Technical Field

[0001] This utility model belongs to the technical field of door and window cutting equipment, and in particular relates to a metal door and window cutting equipment. Background Technology

[0002] With the development of the construction industry, houses cannot do without doors and windows. In order to extend the service life of doors and windows, most doors and windows are made of metal. Depending on the installation location of different doors and windows, metal door and window components need to be cut and processed to meet the installation requirements.

[0003] In the prior art, Chinese utility model patent with patent number 202320451521.3 discloses a metal door and window cutting device, including: a base; a processing table assembly connected to the base; a positioning assembly connected to the processing table assembly; and a cutting device connected to the processing table assembly for cutting metal door and window components. The positioning assembly includes: a first limiting assembly connected to the processing table assembly for lateral limiting of the metal door and window components; and a second limiting assembly connected to the first limiting assembly for longitudinal limiting of the metal door and window components. This device is reasonably designed, and through the cooperation of the first and second limiting assemblies, dual limiting of the metal door and window components to be cut can be achieved.

[0004] In the existing technology, by cooperating with the first limiting component and the second limiting component, dual limiting of the metal door and window components to be cut can be achieved, thus completing the stable cutting process of the metal door and window components. However, there are still some shortcomings in the overall use:

[0005] First, although the existing technology can provide double-limiting for metal door and window components, the two sides of the cutting seam are not fixed during the cutting process. This causes the material to easily deviate due to vibration during the cutting process, resulting in more burrs on the cut and a decrease in the quality of the finished product. Additional time is required for grinding afterward. In severe cases, excessive vibration can also cause the saw blade to tilt, seriously affecting the cutting accuracy.

[0006] Secondly, when cutting metal door and window components, the frictional vibration and flying metal chips generated by the high-speed rotating blade are very dangerous to operators at close range. At the same time, the cutting process also produces irritating gases that can irritate the respiratory tract and affect the health of workers if inhaled. Utility Model Content

[0007] To overcome the shortcomings of existing technologies, this utility model provides a metal door and window cutting device. This utility model solves the technical problem that, during the cutting of metal door and window components, the lack of fixed vibration damping on both sides of the cutting kerf leads to material vibration during the cutting process, causing the cutting disc to shift, resulting in an uneven cutting kerf, or even cutting kerf misalignment, and ultimately reducing cutting accuracy. Furthermore, it also solves the technical problem of the difficulty in cleaning up the debris and irritating gases generated during the cutting process.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a metal door and window cutting device, comprising a workbench, two symmetrical mounting plates fixedly installed on the upper surface of the workbench, a conveying roller rotatably mounted between the two mounting plates, a bracket slidably mounted above the mounting plates, a cutting disc disposed below the bracket, two sets of limiting rods slidably passing through both sides of the cutting disc, pressure plates fixedly mounted at the bottom of the two sets of limiting rods, a limiting plate threadedly fixed at the top of the limiting rods, a support rod fixedly mounted on one side of the limiting plate, a lever rotatably mounted at the top of the support rod, a column fixedly mounted on the upper surface of the bracket, the top of the column rotatably connected to the lower surface of the lever at an eccentric point, two symmetrically arranged dust suction pipes slidably mounted on the top of the bracket, a fixing ring fixedly mounted at the top of the dust suction pipes, one end of the fixing ring rotatably connected to the end of the lever away from the support rod.

[0009] Optionally, a vacuum cleaner is fixedly installed on the top of the bracket, the vacuum cleaner's suction end is connected to a telescopic tube and is connected to the top of the suction tube, and the bottom of the suction tube is inclined towards the cutting disc.

[0010] Optionally, two sets of electric slide rails are fixedly installed on the upper surface of the worktable and on both sides of the mounting plate. Second electric sliders are slidably installed inside the two sets of electric slide rails, and the bracket is fixed on the upper surface of the two second electric sliders.

[0011] Optionally, a spring sleeved on the outside of the limiting rod is fixedly installed between the lower surface of the bracket and the upper surface of the pressure plate.

[0012] Optionally, two symmetrically arranged electric slide rails are fixedly installed on both sides of the two sets of electric slide rails II and on the upper surface of the worktable. A first electric slider is slidably installed inside the electric slide rails I. A support plate is fixedly installed on the upper surface of the first electric slider. A cylinder is slidably installed inside the support plate. A clamping block is fixedly installed at the output end of the cylinder.

[0013] Optionally, the support plate has a movable groove inside, the cylinder slides inside the movable groove, and the sliding end of the cylinder is threadedly fixed with a threaded knob.

[0014] Optionally, a downwardly inclined baffle is fixedly installed inside the bracket and slides on the surface of the mounting plate, and a downwardly inclined nozzle is installed through the inside of the bracket.

[0015] Optionally, a base is fixedly installed on the lower surface of the workbench. The base is a box-shaped structure, and a filter plate is fixedly installed inside the base. A material discharge chute communicating with the base is opened in the middle of the workbench and between two mounting plates.

[0016] In summary, compared with the prior art, the metal door and window cutting equipment provided by this utility model has the following beneficial effects:

[0017] This utility model, through the setting of limiting rod, pressure plate, lever and dust suction pipe, can further fix both sides of the cutting seam when cutting door and window components, to avoid the saw blade shifting due to material vibration during the cutting process, which would reduce the quality of the cut, increase the work of subsequent processing, and improve the product quality. At the same time, it can ensure the dust removal and removal of irritating odors when cutting door and window components of different thicknesses.

[0018] This utility model, through the installation of a mounting plate, conveying rollers, baffles, and a vacuum cleaner, can block debris during the cutting of door and window components, protecting the safety of surrounding workers and the working environment. At the same time, it can wash and cool the debris, further improving dust removal and extending the service life of the cutting disc. Attached Figure Description

Detailed Implementation

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] refer to Figure 1 A metal door and window cutting device includes a base 10, which is box-shaped. A worktable 11 is fixedly installed on the upper surface of the base 10. Two symmetrical mounting plates 12 are fixedly installed on the upper surface of the worktable 11. Multiple conveying rollers 13 are rotatably mounted between the two mounting plates 12. There are gaps between the multiple conveying rollers 13 for cutting door and window components. In use, the door and window components are placed on the surface of the conveying rollers 13. Due to the rotation of the conveying rollers 13, the operator can push the components forward outside the multiple conveying rollers 13, which can quickly and conveniently push the components to the cutting position and reduce labor intensity.

[0030] Further reference Figure 1 and Figure 5Two sets of symmetrically arranged electric slide rails are fixedly installed on the upper surface of the workbench 11, located outside the mounting plate 12. Two sets of first electric sliders 15 are slidably installed inside the two sets of electric slide rails 11. Each set of first electric sliders 15 is symmetrically arranged. A support plate 16 is fixedly installed on the upper surface of the first electric slider 15. A moving groove 17 is opened inside the support plate 16. A cylinder 18 is slidably installed inside the moving groove 17. A clamping block 19 is fixedly installed at the output end of the cylinder 18. The clamping block 19 is corner-shaped and used to lock at the upper corner of the door / window component to improve the fixing effect. A threaded knob 20 is threadedly fixed to the sliding end of the cylinder 18 to fix the cylinder 18 to the support plate 16. In use, when the metal door / window is moved to the appropriate position, the two sets of first electric sliders 15 will respectively... At both ends of the door and window components, the height of the cylinder 18 on the support plate 16 is roughly adjusted according to the thickness of the components. During adjustment, the knob 20 is rotated to disengage the knob 20 from the cylinder 18, releasing the cylinder 18 from its limit position, allowing the cylinder 18 to move up and down so that the corner of 19 corresponds to the upper surface of the component. After adjustment, the threaded knob 20 is screwed into the cylinder 18 to pre-fix and limit the cylinder 18 on the support plate 16. Then, the cylinder 18 is controlled to work, driving the two clamping blocks 19 to move in the center, clamping the component in the center, and quickly fixing it. Then, the height of 19 is adjusted again so that the corner of 19 is just stuck at the end of the component, further improving the fixing effect. The first electric slider is slidably set to facilitate the fixing of components of different widths and lengths, speeding up the work efficiency.

[0031] Further reference Figure 1 , Figure 7 and Figure 8 Two symmetrically arranged electric slide rails are fixedly installed between the two sets of electric slide rails and on the upper surface of the worktable 11. A second electric slider 21 is slidably installed inside the electric slide rails 21. A U-shaped bracket 22 is fixedly installed on the upper surface of the two second electric sliders 21. A hydraulic cylinder 23 is fixedly installed on the upper surface of the bracket 22. The output end of the hydraulic cylinder 23 slides through the bracket 22, and a mounting block 24 is fixedly installed at its end. A cutting disc 26 is rotatably installed on one side of the mounting block 24, and a motor 25 for driving the cutting disc 26 is fixedly installed on the other side of the mounting block 24. When cutting door and window components, the second electric slider 21 moves the bracket 22 to adjust the lateral position of the cutting disc 26, enabling cutting of components of different lengths. After adjustment, the hydraulic cylinder 23 moves the mounting block 24 downwards, causing the cutting disc 26 to move downwards to cut the fixed component.

[0032] It should be noted that the electric slide rail, the first electric slider 15 and the second electric slider 21 are all existing technologies. In actual production, controllers or control circuits are set outside these driving components, and existing technologies can be used. They are not technical problems that this solution needs to solve, so this solution will not elaborate on them.

[0033] Further reference Figure 1 , Figure 2 , Figure 3 , Figure 4 Figure 7 and Figure 8 Two sets of limiting rods 28 are slidably mounted on the lower surface of the base 10. The two sets of limiting rods 28 are located on both sides of the cutting disc 26. A pressure plate 29 is fixedly mounted on the bottom end of the limiting rod 28. There is a connecting structure between the two pressure plates 29, which are fixed to each other. The pressure plate 29 is located below the cutting disc 26. A spring 30 sleeved on the outside of the limiting rod 28 is fixedly installed between the upper surface of the pressure plate 29 and the lower surface of the bracket 22. A limiting plate 31 is threadedly fixed to the top of the limiting rod 28. The limiting plate 31 can be disassembled from the limiting rod 28, which facilitates the replacement of the cutting disc 26. The lower surface of the mounting block 24 is connected to the lower surface of the base 10. The pressure plates 29 are fixed to each other. When the cutting disc 26 moves downward to cut, the pressure plates 29 are fixed to the mounting block 24, causing the pressure plates 29 to move downward together with the cutting disc 26. Since the pressure plates 29 are below the cutting disc 26, they first contact the door and window components to further fix the required cutting area. Then the cutting disc 26 performs cutting work. During the cutting process, the pressure plate 29 limit components keep it stable, and the spring 30 dampens the pressure plates 29, further improving the stability effect and preventing the saw blade from shifting due to material vibration during the cutting process, thus reducing the cutting accuracy and quality.

[0034] In this explanation, spring 30 is a shock-absorbing spring that can absorb vibrations without increasing them. It is existing technology and is made of shock-absorbing material. It will not be described in detail in this solution.

[0035] Further reference Figure 3 and Figure 4A column 32 is fixedly installed on the upper surface of the bracket 22, and a support rod 33 is fixedly installed on the upper surface of the limiting plate 31. A lever 34 is rotatably installed at the top of the support rod 33, and the bottom of the lever 34 is eccentrically connected to the column 32. A suction pipe 35 is slidably installed inside the bracket 22. The part of the suction pipe 35 located inside the bracket 22 is inclined towards the cutting disc 26. A fixing ring 36 is fixedly installed at the top of the suction pipe 35. One end of the fixing ring 36 is rotatably connected to the end of the lever 34 away from the support rod 33. A vacuum cleaner 37 is fixedly installed on the upper surface of the bracket 22. The suction end of the vacuum cleaner 37 is connected to a telescopic pipe and is connected to the suction pipe 35. When the door and window component cutting pressure plate 29 limits it, the pressure plate 29 moves downward to press the component, causing the pressure plate 29 to move upward, driving the limiting plate 31 connected to it to move upward as well, thereby driving the support rod 33 to move upward. The bottom of lever 34 is rotatably connected to column 32. As support rod 33 moves upward, it drives the hinged end of lever 34 to move upward, thereby causing the other end of lever 34 to move downward. Since lever 34 is hinged to fixing ring 36 that fixes suction pipe 35, it can drive suction pipe 35 downward, bringing suction pipe 35 closer to the cutting edge of cutting disc 26 for dust and air suction. The sliding installation of suction pipe 35 avoids uneven component thickness. When cutting thinner components, the cutting disc 26 moves a greater distance downward, making suction pipe 35 farther from the cutting edge, reducing its effectiveness. When cutting thicker components, if suction pipe 35 is too close to the cutting edge, it may interfere with the component. The sliding suction pipe 35 avoids these problems and can be used to cut components of different thicknesses, greatly improving its effectiveness.

[0036] Further reference Figure 1 , Figure 3 and Figure 6 The workbench 11 has a feeding chute inside and between two mounting plates 12. The mounting plates 12 have sliding grooves on both sides. The inner side of the bracket 22 is fixedly installed with a downwardly inclined baffle 27 that slides inside the sliding groove. When the position of the cutting disc 26 is adjusted, the baffle 27 can move with the bracket 22 so that the baffle 27 is always located on both sides of the cutting disc 26. When cutting door and window components, the baffle 27 can block the debris generated during cutting. Because the baffle 27 is inclined downward, the blocked debris falls down through the gap of the conveying roller 13 and into the interior of the base 10 for collection.

[0037] Further reference Figure 3The bracket 22 has downward-sloping nozzles 38 fixedly installed on both sides. The upper end of the nozzles 38 is connected to a water pump. When cutting doors and windows, water is sprayed on the cutting area and the cutting disc 26, which can reduce the generation of smoke and dust, improve the dust removal effect, and also cool down the components and the cutting disc 26, improve the cutting quality and extend the service life of the cutting disc 26. The sprayed water will fall into the base 10 after being blocked by the baffle 27.

[0038] Further reference Figure 3 The top of the base 10 is connected to the material feeding trough of the worktable 11. A filter screen 39 is fixedly installed inside the base 10. The filter screen 39 is used to filter cutting debris in the water, so as to separate it from the water and enable the water to be recycled. A drainage hole is provided at the bottom of the base 10. The diagram of the drainage hole is not shown in this figure. Since the drainage hole is a conventional setting in this technical field and is only used to drain water, it will not be described in detail in this solution.

[0039] The specification and claims use certain terms to refer to specific components. Those skilled in the art will understand that hardware manufacturers may use different names to refer to the same component. This specification and claims do not distinguish components based on differences in name, but rather on differences in function. The term "comprising" throughout the specification and claims is an open-ended term and should be interpreted as "comprising but not limited to." "Approximately" means that within an acceptable margin of error, those skilled in the art can solve the technical problem and substantially achieve the technical effect within a certain margin of error.

[0040] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a product or system comprising a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a product or system. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the product or system that includes said element.
