Description

Technical Field

[0001] This utility model relates to the technical field of aluminum plate processing mechanisms, and in particular to an aluminum plate groove-opening mold. Background Technology

[0002] Aluminum curtain walls are a modern building exterior wall material, mainly composed of aluminum sheets (aluminum alloy sheets), used to provide an aesthetically pleasing exterior surface and protective function for buildings. In the processing of aluminum sheets, the grooving process is usually completed on a CNC engraving machine. This grooving process typically involves creating through-grooves that penetrate the aluminum sheet to facilitate interlocking and other applications.

[0003] However, in some special applications, it is necessary to cut grooves of a certain depth into the aluminum sheet, but these grooves must not penetrate the sheet. These grooves allow for manual bending of the aluminum sheet at a small bending angle. However, due to the thinness of the aluminum sheets used in aluminum curtain walls and the unevenness of the engraving machine's worktable, in actual processing, there are instances where the grooves penetrate the sheet or are not properly cut, making it difficult to guarantee the processing accuracy of the grooves.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a groove mold for aluminum plates, which aims to solve the technical problem of inconsistent groove depths on aluminum plates in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A groove-cutting mold for aluminum plates includes a mounting part, a narrowing part, and an abutment part that are connected sequentially and coaxially. The outer diameter of the mounting part is larger than that of the abutment part. The mounting part is provided with fasteners for connecting to the head of a carving machine. The abutment part is provided with a central hole through which the cutting tool of the machine head passes, and the central hole extends to the mounting part. The abutment part is provided with several through slots communicating with the central hole, and the ends of all the through slots extend to the outer wall of the abutment part. The multiple through slots divide the abutment part into several arc-shaped blocks.

[0008] Furthermore, the fastener consists of three or more locking screws, all of which are arranged in a circumferential array on the mounting part, and the mounting part is threadedly connected to the locking screws.

[0009] Furthermore, an installation step is provided on the inner side of the mounting part.

[0010] Furthermore, the thickness of the mounting portion is greater than the thickness of the narrowing portion.

[0011] Furthermore, the outer diameter of the narrowing portion gradually decreases towards the contact portion; the wall of the narrowing portion is provided with several windows communicating with the central hole.

[0012] Furthermore, the bottom of the window extends to the top of the abutment; and the top width of the window is greater than the bottom width.

[0013] Furthermore, there are four arc blocks arranged in a circumferential array.

[0014] Furthermore, the bottom edge of the arc block is chamfered.

[0015] Beneficial effects:

[0016] This utility model provides a groove mold for aluminum plates, which has the following advantages: (1) The mounting part can be directly fixed to the head of the engraving machine by fasteners.

[0023] This utility model provides a groove-cutting mold for aluminum plates. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model.

[0025] Please see Figures 1 to 4 As shown, this utility model provides a groove-cutting mold for aluminum plates. The mold is installed on the head a of a carving machine. The head a is a prior art technology capable of groove-cutting aluminum plates. Specifically, the head a includes a cylinder lifting assembly a1, a rotary drive assembly a2 located at the output end of the cylinder lifting assembly a1, and a cutting tool a3 located at the output end of the rotary drive assembly a2. The cylinder lifting assembly a1 drives the rotary drive assembly a2 to move up and down, thereby adjusting the position of the cutting tool a3 in the vertical direction; the rotary drive assembly a2 drives the cutting tool a3 to rotate, and the carving machine drives the head a to move in a planar motion, thereby achieving groove-cutting on the aluminum plate.

[0026] The aforementioned aluminum plate groove mold includes a mounting part 1, a narrowing part 2, and an abutment part 3 that are connected sequentially and coaxially. The outer diameter of the mounting part 1 is larger than the outer diameter of the abutment part 3. The mounting part 1 is provided with a fastener 4, which is used to connect with the head of the engraving machine. The abutment part 3 is provided with a central hole 5 through which the cutting tool of the machine head passes, and the central hole 5 extends to the mounting part 1. The abutment part 3 is provided with several through slots 31 that communicate with the central hole 5. The ends of all the through slots 31 extend to the outer wall of the abutment part 3, and the multiple through slots 31 divide the abutment part 3 into several arc-shaped blocks 32.

[0027] During installation, align the center hole 5 with the rotary drive assembly, place the cutting tool inside the center hole 5, and then install the fastener 4 at the lower end of the rotary drive assembly to lock the position of the mounting part 1. Simultaneously, adjust the distance between the bottom of the cutting tool and the bottom of the abutment part 3 according to the depth of the groove, ensuring that this distance matches the depth of the groove.

[0028] During processing, the cylinder lifting assembly drives the rotary drive assembly to descend, causing the bottom of the contact part 3 to contact the upper surface of the aluminum plate. The length of the cutting tool penetrating into the aluminum plate is the processing depth of the groove. By ensuring that the relative position between the cutting tool and the aluminum plate remains unchanged, the function of consistent groove opening depth is achieved, thus ensuring the processing accuracy of the groove. Since the cutting tool generates a lot of heat during the groove processing, the coolant spray pipe can be aimed at the through groove 31. The coolant enters the central hole 5 through the through groove 31 and reaches the processing position, thereby achieving a cooling effect.

[0029] In the above, by setting the mounting part 1, the narrowing part 2 and the abutment part 3 with gradually decreasing outer diameter, the overall weight can be reduced, thereby reducing the workload of the cylinder lifting assembly.

[0030] In the above, the mounting part 1, the narrowing part 2, and the abutting part 3 are integrally formed to improve the stability of the overall structure.

[0031] It should be noted that, since the engraving machine uses a cylinder lifting assembly to achieve the lifting and lowering movement of the tool, and the cylinder lifting assembly controls the movement of its extension rod through air pressure, when the worktable of the engraving machine is uneven, the pressure between the contact part 3 and the aluminum plate will be too large or too small, which will cause the air pressure in the cylinder to change accordingly. According to the movement characteristics of the cylinder, this air pressure change causes the extension rod to have a slight lifting and lowering movement to cope with the slight distance change between the aluminum plate and the tool caused by the unevenness of the worktable.

[0032] In a preferred embodiment, see [reference] Figure 1 The fastener 4 consists of three or more locking screws 41, preferably four, arranged in a circumferential array on the mounting part 1. The mounting part 1 is threadedly connected to the locking screws 41. During installation, four locking screws 41 are screwed in, with the ends of the screws 41 abutting against the outer wall of the rotary drive assembly to lock the position of the mounting part 1. This configuration ensures stable installation of the aluminum plate groove mold without damaging the machine head structure.

[0033] In a preferred embodiment, see [reference] Figure 1 , 3 The mounting part 1 has an mounting step 11 on its inner side, and the lower end of the rotary drive assembly is located on the mounting step 11 to achieve the purpose of quick installation. In addition, the mounting step 11 can ensure that the mounting part 1 is installed horizontally, so that the bottom of each arc block 32 is on the same horizontal plane.

[0034] In a preferred embodiment, the thickness of the mounting portion 1 is greater than the thickness of the narrowing portion 2. When the thickness of the mounting portion 1 is sufficiently large, the stability of the locking screw 41 connection can be guaranteed. When the thickness of the narrowing portion 2 is relatively small, the weight of the aluminum plate groove mold can be effectively reduced.

[0035] In a preferred embodiment, see [reference] Figure 3 The outer diameter of the narrowing portion 2 gradually decreases towards the abutting portion 3; the wall of the narrowing portion 2 is provided with several windows 21 communicating with the central hole 5, preferably four windows 21 arranged in a circumferential array. By setting the windows 21, the operator can use tools to install and remove the cutting tool, and adjust the installation height of the cutting tool so that the distance between the bottom of the cutting tool and the bottom of the arc block 32 is consistent with the depth of the groove to be processed, thereby improving the applicability.

[0036] Further, see Figure 3 The bottom of the window 21 extends to the top of the abutment portion 3; and the top width of the window 21 is greater than the bottom width. This configuration maximizes the area of ​​the window 21 while ensuring the stability of the connection between the narrowing portion 2 and the abutment portion 3.

[0037] In a preferred embodiment, see [reference] Figure 4 There are four arc blocks 32 arranged in a circumferential array, meaning there are four through slots 31, and the included angle between any two adjacent through slots 31 is 90°. In practical applications, the coolant spray nozzle is aligned with any through slot 31. After the coolant enters the central hole 5 from the through slot 31, part of the coolant is directly discharged from the opposite through slot 31, while the other part is discharged from the side through slot 31. Since the two corresponding through slots 31 are on the same straight line, the coolant can be quickly discharged after heat exchange with the tool and aluminum plate, while also carrying away the debris generated during processing, preventing debris from lingering near the processing station and scratching the surface of the aluminum plate.

[0038] In a preferred embodiment, see [reference] Figure 4 The bottom edge of the arc block 32 is chamfered 33. When the engraving machine head moves, the chamfer 33 can prevent the bottom corner of the arc block 32 from scratching the surface of the aluminum plate, thus ensuring the surface quality of the aluminum plate.

[0039] Optionally, the chamfer 33 can be a right angle or a rounded corner.

[0040] In summary, this utility model, through the fastener 4, can be directly installed on the aluminum plate groove mold and fixed on the head of the engraving machine. The distance between the bottom of the arc block 32 and the bottom of the tool is the processing depth of the groove. By controlling the position of the arc block 32 and the tool to be relatively fixed, the bottom of the arc block 32 always abuts against the upper surface of the aluminum plate, achieving the function of consistent groove processing depth and improving the processing accuracy of the groove. The peripheral wall of the narrowing part 2 is provided with a window 21, which facilitates the adjustment of the tool installation height, thereby adjusting the distance between the bottom of the tool and the bottom of the arc block 32, meeting the processing of grooves of various depths, and has wide applicability.
