Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile processing, and in particular to an aluminum profile groove cutting device and a cutting method thereof. Background Art

[0002] When welding aluminum profiles, it is usually necessary to cut a groove at the welding end first. Welding at the groove can reduce deformation during welding, make the shape of the aluminum profile more regular, avoid warping or deformation after welding, and improve the bearing capacity of the welded structure.

[0003] Thin-walled square tube aluminum profiles are square tube fittings. When cutting the groove, due to the thin wall thickness of the square tube aluminum profile, the cutting tool applies a downward force to its end when cutting. Therefore, it is very easy to cause the tube wall to bend and deform inward, making the groove surface uneven. For the same groove, the angles of the grooves at different positions are different. In order to solve the above problems, the existing patent publication number is CN117943604A, and the publication date is April 30, 2024. The patent name is an aluminum profile groove cutting device and a cutting method thereof. The cutting device discloses a solution for aluminum profile groove cutting, specifically, by using a top pressure block to support the cutting position, applying a supporting force to the side wall of the square tube aluminum profile to be cut. During cutting, the supporting force is balanced with the force applied by the cutting tool to the side wall of the square tube aluminum profile, thereby effectively preventing the groove surface from being uneven and ensuring that the weld gap size is consistent.

[0004] The above-mentioned prior art solutions still have the following defects: 1. When cutting the thin-walled square tube aluminum profile, due to the existence of the supporting assembly, the cutting assembly can only cut one side of the thin-walled square tube aluminum profile, that is, cut a single-sided bevel. When it is necessary to cut multiple bevels, the position of the thin-walled square tube aluminum profile needs to be changed, which leads to cumbersome steps; 2. In the process of cutting the thin-walled square tube aluminum profile, the top pressure block will also be cut. It is concluded that the top pressure block is a disposable consumable item, which increases the cost of aluminum profile cutting and adds the step of replacing the top pressure block, which is not conducive to quick cutting. Therefore, the present application provides an aluminum profile bevel cutting device and a cutting method thereof to meet the needs. Summary of the invention

When it is necessary to cut multiple bevels, the position of the thin-walled square tube aluminum profile needs to be changed, which leads to cumbersome steps; 2. during the cutting process of the thin-walled square tube aluminum profile, the top pressure block will be cut at the same time, which leads to the conclusion that the top pressure block is a disposable consumable item, thereby increasing the cost of aluminum profile cutting and adding the step of replacing the top pressure block, which is not conducive to quick cutting.

DETAILED DESCRIPTION

[0030] Embodiment 1: Figures 1 to 7 As shown, an embodiment of the present invention provides an aluminum profile bevel cutting device, comprising: a workbench 1; a clamping portion, located at the top of the workbench 1, used to clamp and fix the square tube aluminum profile to be cut, and is configured to be inserted from the side away from the cut side of the square tube aluminum profile, to fix and support the cutting edge, and to adjust according to the cutting angle; a cutting assembly 2, located at the top of the workbench 1, used to cut the square tube aluminum profile fixed by the clamping portion; a support table 3, located at the top of the workbench 1, used to support the bottom end of the square tube aluminum profile.

[0031] like Figure 3 As shown, it also includes: a hydraulic component 20 installed on the workbench 1, used to drive the cutting component 2 to move upward or downward to assist in adjusting the cutting angle of the cutting component 2.

[0032] It should be noted that the workbench 1 includes a power supply device, which provides kinetic energy for the linear drive 4, the first drive 8, the cutting assembly 2, the hydraulic assembly 20 and the micro air pump 17 to maintain the normal operation of the equipment; the support table 3 is only an auxiliary support for the bottom end of the square tube aluminum profile. During the cutting process, the support table 3 is never in contact with the cutting assembly 2, so it will not affect the cutting; the cutting assembly 2 includes a rotatable fixed frame, which drives the cutting assembly 2 to rise and fall through the hydraulic assembly 20 and rotates the fixed frame, thereby changing the cutting angle.

[0033] Embodiment 2: Figures 1 to 7 As shown, the clamping part includes: a linear drive member 4, which is installed on the workbench 1; a clamping assembly, which is located on the workbench 1 and is configured to move forward or backward through the linear drive member 4 so that the clamping assembly enters the square tube aluminum profile or leaves the square tube aluminum profile; a fixing pile 5, which is installed at one end of the linear drive member 4 and is used to fix the clamping assembly.

[0034] The clamping assembly includes: a rotating disk 6, which is installed on the side of the fixed pile 5 away from the linear drive member 4; a support rod 7, which is installed on the rotating disk 6; a first drive member 8, which is installed on the side of the fixed pile 5 close to the linear drive member 4, and is used to drive the rotating disk 6 to rotate; four groups of air bags 9, which are respectively installed around the support rod 7, and are arranged so that after the four groups of air bags 9 are fully inflated, the air bags 9 are square; four groups of top pressure plates 10, each group of air bags 9 is equipped with a group of top pressure plates 10 on the side away from the support rod 7, which are used to support one side of the inner wall of the square tube aluminum profile respectively, and are arranged so that when the air bags 9 are fully inflated, the top pressure plates 10 are fixed; an inflation assembly, which is installed on the rotating disk 6, and is used to inflate the four groups of air bags 9; two groups of adjustment assemblies, which are used to adjust the support angle so as to further fix the square tube aluminum profile, and the two groups of adjustment assemblies are respectively installed on a group of top pressure plates 10, and the two groups of top pressure plates 10 are any two groups of top pressure plates 10 that are the farthest apart.

[0035] The inflation assembly includes: an air collecting plate 16, installed on the rotating plate 6; a micro air pump 17, installed on the air collecting plate 16, used to supply air to the air collecting plate 16; four groups of air guide tubes 18, one end of each group of air guide tubes 18 is connected to a group of air bags 9, and the other end is connected to the air collecting plate 16, so that the gas can be input into the air bags 9.

[0036] It should be noted that the top of the linear drive member 4 is connected to the fixed plate through the fixed plate, and the output end of the first drive member 8 is connected to the rotating disk 6 through the fixed pile 5. When the first drive member 8 is started, the rotating disk 6 will rotate; a ring is installed on the side of the support rod 7 away from the rotating disk 6, and four groups of air bags 9 are fixed around the ring. When the micro air pump 17 is started, the outside gas enters the air collecting disk 16, and the gas is respectively input into the four groups of air guide tubes 18 and enters the corresponding air bags 9. After the air bags 9 expand to the maximum limit, the side of the air bags 9 close to the top pressure plate 10 is horizontal, thereby pushing the top pressure plate 10, so that the top pressure plate 10 abuts against the inner wall of the square tube aluminum profile. There are top pressure plates 10 on the four side walls, so that the fixation is more firm.

[0037] Embodiment 3: Figures 4 to 7 As shown, the adjustment component includes: multiple groups of elastic members 11, which are installed on the side of the top pressure plate 10 close to the airbag 9 and are respectively located on both sides of the airbag 9; two groups of fixed frames 12, which are respectively installed on both sides of the airbag 9, and the top ends are fixedly connected to the multiple groups of elastic members 11; two groups of lead screws 13, each group of fixed frames 12 is equipped with a group of lead screws 13, and it is arranged that the lead screws 13 pass through the fixed frames 12 close to the rotating disk 6; two groups of transmission rods 14, each group of lead screws 13 is equipped with a group of transmission rods 14, and it is arranged that when the lead screw 13 rotates, the transmission rod 14 moves forward or backward along the direction of the lead screw 13.

[0038] It also includes: a baffle 15, which is installed on the side of the transmission rod 14 away from the rotating disk 6 and is rotatably connected to the four groups of transmission rods 14, so that the inclination angle of the baffle 15 can be changed after the transmission rods 14 of the two groups of adjustment components are adjusted.

[0039] The structure also includes: a plurality of groups of rotating handles 19 , and each group of the lead screw 13 extending out of the fixed frame 12 is respectively equipped with a group of rotating handles 19 to facilitate the rotation of the lead screw 13 .

[0040] It should be noted that before cutting, the user first adjusts the adjustment component, specifically, turns the rotating handle 19 to rotate the lead screw 13, thereby driving the transmission rod 14 to move. When adjusting the same group of adjustment components, the two groups of transmission rods 14 in the same adjustment component move the same length, so that one side of the baffle 15 moves to form a certain angle, which is set according to the cutting groove. The transmission rod 14 and the baffle 15 are connected by a rotating wheel, so that the upper and lower sides of the baffle 15 adjust the rotation angle according to the movement of the transmission rod 14; the baffle 15 can not only provide auxiliary support, but also prevent the waste generated by cutting from entering the finished square tube aluminum profile, so as to reduce the time for cleaning.

[0041] like Figure 8As shown, the present invention also provides a method for cutting an aluminum profile groove, comprising the following steps: Step 1: Rotate multiple groups of rotating handles 19 respectively, and adjust the position of the transmission rod 14 on the lead screw 13 according to the groove cutting shape, so as to adjust the inclination angle of the baffle 15; Step 2: Place the square tube aluminum profile on the support table 3, and the linear drive member 4 drives the clamping assembly to be inserted from the side away from the cut side of the square tube aluminum profile, and after moving to the cutting edge, the linear drive member 4 stops moving; Step 3: Start the micro air pump 17 to fill the four groups of air bags 9 with external gas. After the air bags 9 are fully expanded, the top pressure plate 10 is squeezed so that the top pressure plate 10 supports the inner wall of the square tube aluminum profile. After starting the hydraulic assembly 20 and the cutting assembly 2, the cutting angle is adjusted to cut the square tube aluminum profile; Step 4: When it is necessary to change the side wall of the square tube aluminum profile cut, start the first drive member 8 to rotate the rotating disk 6, so that the square tube aluminum profile is rotated and cut again.

[0042] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0043] The above is only a preferred embodiment of the present invention.
