Abstract
Description
Technical Field
[0001] This utility model belongs to the field of aluminum tube cutting technology, specifically an aluminum tube cutting device. Background Technology
[0002] In the vast field of aluminum tube processing, aluminum tube cutting is a fundamental and crucial process, and its processing quality and efficiency have a profound impact on the entire production process. Currently, there are multiple approaches to aluminum tube cutting technology, but each is accompanied by significant drawbacks.
[0003] Manual sawing still has some application in small-scale processing scenarios. Operators use hand-held saws to cut aluminum tubes, a method heavily reliant on manual skill and physical strength. Because it's difficult to maintain absolute stability and uniformity in the applied force, the cutting process is extremely slow, significantly limiting production efficiency. Furthermore, the cut surfaces produced by manual sawing are often uneven, with jagged edges and potentially numerous burrs. Subsequent secondary processing, such as grinding and finishing, is required to meet usage standards, undoubtedly increasing both production and time costs.
[0004] Traditional mechanical cutting equipment, such as some cutting machines using circular saw blades, while improving cutting efficiency to some extent, also presents significant problems. When a circular saw blade is cutting aluminum tubes at high speed, it always cuts in one direction. This causes uneven stress on the aluminum tube, leading to deformation, especially for thinner and longer aluminum tubes. Deformed aluminum tubes, when used in subsequent high-precision assembly or other processing stages, will have difficulty fitting properly due to dimensional deviations, reducing the product yield.
[0005] In summary, existing aluminum tube cutting methods struggle to balance efficiency, quality, and cost control, necessitating an innovative aluminum tube cutting device to meet the aluminum tube processing industry's demand for efficient, high-quality, and low-cost cutting processes. Utility Model Content
[0006] To address the problem of balancing efficiency and quality in existing aluminum tube cutting methods, this invention provides an aluminum tube cutting device.
[0007] This utility model is achieved through the following technical solution:
[0008] An aluminum tube cutting device includes several axial guide mechanisms spaced apart front to back, capable of axially conveying aluminum tubes. A circumferential rolling support mechanism is provided between adjacent axial guide mechanisms. A cutting machine capable of cutting the aluminum tube is provided on one side between two adjacent circumferential rolling support mechanisms. The circumferential rolling support mechanism includes a support plate with two circumferential rolling support wheels arranged opposite each other on the support plate. The axial direction of the circumferential rolling support wheels is consistent with the conveying direction of the aluminum tube. A first telescopic cylinder capable of driving its lifting and lowering is supported and connected to the bottom of the support plate. It also includes pressure rods and pressure wheels corresponding to the upper and lower dimensions of the two circumferential rolling support mechanisms adjacent to the cutting machine. The pressure rods are driven to move left and right reciprocally by an electric cylinder.
[0009] A further improvement of this invention is that the cross-section of the compression bar is rectangular.
[0010] A further improvement of this utility model is that the lower side of the pressure rod is covered with a protective layer made of rubber.
[0011] A further improvement of this utility model is that it also includes a mounting plate disposed on the upper side of the circumferential rolling support mechanism, an electric cylinder being positioned and installed on the lower side of the mounting plate, and two guide seats being positioned and installed on the mounting plate; the two ends of the pressure rod are connected to guide rods that can slide and guide with the guide seats, and the telescopic end of the electric cylinder is connected to the end of a guide rod.
[0012] A further improvement of this utility model is that it also includes a mounting bracket disposed on the upper side of the mounting plate, and a second telescopic cylinder is connected and installed between the mounting bracket and the mounting plate.
[0013] A further improvement of this utility model is that a first guide member capable of vertically lifting and lowering the support plate is also connected and installed on the lower side of the support plate.
[0014] A further improvement of this utility model is that the support plate is provided with a mounting seat for connecting and installing the circumferential rolling support wheel, and the upper side of the mounting seat is provided with a corresponding wedge-shaped mounting surface.
[0015] A further improvement of this utility model is that the axial guide mechanism includes an axial guide mechanism bracket, on which axial support rollers arranged in a V-shape and facing each other are mounted.
[0016] As can be seen from the above technical solutions, the beneficial effects of this utility model are:
[0017] In operation, the circumferential rolling support mechanism is at its bottom position (i.e., the first telescopic cylinder retracts), and the aluminum tube is supported on the axial guide mechanism and conveyed from front to back through the axial guide mechanism. When it reaches the cutting position (based on the cutting blade of the cutting machine), the first telescopic cylinder drives the circumferential rolling support wheels to rise synchronously until the paired circumferential rolling support wheels can lift the aluminum tube (moving it a certain distance away from the support of the axial guide mechanism), so that the upper side of the aluminum tube abuts against the lower surface of the pressure roller and the lower side of the pressure rod. The electric cylinder is controlled to move the pressure rod back and forth, and at the same time, the cutting machine is controlled to slowly approach the aluminum tube (feed cutting), thereby realizing the circumferential cutting (rotation cutting) of the aluminum tube. This effectively avoids the problem of uneven stress and deformation of the aluminum tube caused by always cutting in one direction, ensuring cutting quality and effectively improving the cutting efficiency of the aluminum tube. After cutting is completed, the cutting machine resets, and the first telescopic cylinder drives the circumferential rolling support wheels to descend synchronously, so that the aluminum tube is supported on the axial guide mechanism to continue to be conveyed backward. The overall structure is simple, convenient and efficient in operation, and has good practicality. Attached Figure Description

[0025] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
[0026] like Figure 1-5 As shown, this utility model discloses an aluminum tube cutting device, including a plurality of axial guide mechanisms 1 arranged at intervals to transport aluminum tubes axially (from front to back). A circumferential rolling support mechanism 2 is provided between adjacent axial guide mechanisms 1, wherein two circumferential rolling support mechanisms 2 are provided between two adjacent axial guide mechanisms 1, and one circumferential rolling support mechanism 2 is provided between other two adjacent axial guide mechanisms 1; a cutting machine 5 capable of cutting aluminum tubes is provided on one side (left or right) between two adjacent circumferential rolling support mechanisms 2 (without an axial guide mechanism 1 in between); the circumferential rolling support... The support mechanism 2 includes a support plate 24, on which two circumferential rolling support wheels 21 are mounted, which are arranged opposite each other. The axial direction of the circumferential rolling support wheels 21 is consistent with the aluminum tube conveying direction (i.e., the front-to-back direction). The bottom of the support plate 24 is supported and connected to a first telescopic cylinder 22 that can drive it to rise and fall. The bottom of the first telescopic cylinder 22 can be positioned and installed with the foundation. The device also includes two circumferential rolling support mechanisms 2 (without an axial guide mechanism in the middle) adjacent to the cutting machine 5, with pressure rods 3 corresponding to the left and right directions and pressure wheels 4 with the axial direction in the front-to-back direction, respectively. The pressure rods 3 are driven to move back and forth left and right by an electric cylinder 34.
[0027] In use, the circumferential rolling support mechanism 2 is in the bottom position (i.e., the first telescopic cylinder 22 is retracted), the aluminum tube is supported on the axial guide mechanism 1, and is conveyed from front to back through the axial guide mechanism 1; when it is conveyed to the position where it needs to be cut (based on the cutting disc 51 of the cutting machine 5, such as...), Figure 2As shown, the first telescopic cylinder 22 drives the circumferential rolling support wheels 21 to rise synchronously until the paired circumferential rolling support wheels 21 can lift the aluminum tube (detach it from the support of the axial guide mechanism 1 by a certain distance), so that the upper side of the aluminum tube abuts against the lower surface of the pressure roller 4 (ensuring the reliability of rolling), and the upper side of the aluminum tube abuts against the lower side of the pressure rod 3; the electric cylinder 34 is controlled to move the pressure rod 3 back and forth, and at the same time, the cutting machine 5 is controlled to slowly approach the aluminum tube (feed cutting), thereby realizing the circumferential cutting (rotation cutting) of the aluminum tube, effectively avoiding the problem of uneven local stress and deformation of the aluminum tube caused by always cutting in one direction, ensuring the cutting quality, and effectively improving the cutting efficiency of the aluminum tube. After the cutting is completed, the cutting machine 5 is reset, and the first telescopic cylinder 22 drives the circumferential rolling support wheels 21 to descend synchronously, so that the aluminum tube is supported on the axial guide mechanism 1 to continue to be transmitted backward. The overall structure is simple, convenient and efficient in operation, and has good practicality.
[0028] The cutting machine 5 uses a circular saw blade and has a feeding mechanism for feeding the aluminum tube. Specifically, the feeding mechanism can be a motor-driven ball screw, which works in conjunction with guide rails in the left and right directions.
[0029] Among them, such as Figure 3 As shown, the axial guide mechanism 1 includes an axial guide mechanism bracket 12 mounted on the foundation, on which axial support rollers 11 arranged in a V-shape are mounted. This provides support to the aluminum tube from two opposing directions, ensuring the tube maintains a stable, centered posture during transport and preventing swaying, rolling, or shifting. This ensures the positional accuracy of the aluminum tube throughout the cutting process, improving cutting accuracy and quality. Furthermore, it provides good support for aluminum tubes of different diameters, enhancing the applicability and flexibility of the device.
[0030] The outer surface of the pressure roller 4 can be covered with a rubber layer to achieve reliable rolling pressing and limiting of the aluminum tube.
[0031] The axial support rollers 11 on the axial guide mechanism 1 can be synchronously connected by a synchronous chain and driven by a motor to realize the synchronous transmission of the aluminum tube by each axial support roller 11, thus avoiding slippage and wear (abrasion).
[0032] The pressure bar 3 has a rectangular cross-section. This rectangular cross-section provides a relatively flat and regular pressing surface, allowing for greater contact with the aluminum tube surface during pressing. This provides relatively uniform and stable pressure, ensuring the stability of the aluminum tube's position during cutting and reducing tube swaying or displacement caused by uneven pressing. This contributes to improved cutting accuracy and quality. The rectangular cross-section also gives the pressure bar 3 good structural strength and rigidity under stress, enabling it to withstand greater forces without easily deforming. This ensures that the pressure bar 3 maintains good performance even after repeated use and prolonged operation, extending its service life and improving the overall reliability of the aluminum tube cutting device.
[0033] The lower side of the pressure rod 3 is covered with a protective layer 31 made of rubber. The rubber protective layer 31 is relatively soft and effectively prevents direct hard contact between the pressure rod and the aluminum tube surface when the pressure rod 3 applies pressure, thus preventing scratches, indentations, and other damage to both surfaces. Rubber has good frictional properties, and the presence of the protective layer 31 increases the friction between the pressure rod 3 and the aluminum tube, preventing slippage during the rolling of the aluminum tube and ensuring cutting accuracy and quality. During the reciprocating movement of the pressure rod 3 driven by the electric cylinder 34 and the cutting process of the aluminum tube by the cutting machine 5, certain vibrations and impacts are generated. The rubber protective layer 31, with its good elasticity and cushioning properties, absorbs and buffers these vibrations and impacts, reducing their impact on the aluminum tube and further ensuring its stability during the cutting process. It also reduces noise generated during device operation.
[0034] This device also includes a mounting plate 35 disposed on the upper side of the circumferential rolling support mechanism 2, an electric cylinder 34 positioned on the lower side of the mounting plate 35, and two guide seats 33 positioned on the mounting plate 35; both ends of the pressure rod 3 are connected to guide rods 32 that can slide and guide with the guide seats 33, and the telescopic end of the electric cylinder 34 is connected to the end of one of the guide rods 32. This effectively ensures the reliability and accuracy of the left and right reciprocating movement of the pressure rod 3.
[0035] Furthermore, it also includes a mounting bracket 37 mounted on the upper side of the mounting plate 35. The mounting bracket 37 is connected to the foundation (by connecting a support column). A second telescopic cylinder 36 (multiple cylinders can operate simultaneously) is connected between the mounting bracket 37 and the mounting plate 35, and several vertical guide components (which can be guide rods or sleeve structures) are provided. The second telescopic cylinder 36 enables flexible adjustment of the height position of the pressure rod 3, and flexible adjustment of the pressing force of the pressure rod 3 on the aluminum tube, thus achieving convenience and flexibility in use.
[0036] like Figure 2 , 4As shown, several first guide members 23 (which can be guide rods or sleeve structures) are also connected and installed on the lower side of the support plate 24 to guide its vertical lifting and lowering. The first guide members 23 are set at the four corners of the first telescopic cylinder 22 to ensure the reliability, stability and accuracy of the lifting and lowering action of the circumferential rolling support wheel 21.
[0037] Among them, such as Figure 4 As shown, the support plate 24 is provided with a mounting base 25 for connecting and installing the circumferential rolling support wheel 21. The mounting base 25 has opposing wedge-shaped mounting surfaces on its upper side. This ensures the reliable installation of the circumferential rolling support wheel 21, preventing it from moving outward during the pressing of the aluminum tube and ensuring the consistency of the distance between the paired circumferential rolling support wheels 21.
[0038] In use, the circumferential rolling support mechanism 2 is in the bottom position (i.e., the first telescopic cylinder 22 is retracted), the aluminum tube is supported on the axial guide mechanism 1, and is conveyed from front to back through the axial guide mechanism 1; when it is conveyed to the position to be cut (based on the cutting disc 51 of the cutting machine 5, such as...), the aluminum tube is cut. Figure 2 As shown, the first telescopic cylinder 22 drives the circumferential rolling support wheels 21 to rise synchronously until the paired circumferential rolling support wheels 21 can lift the aluminum tube (detach it from the support of the axial guide mechanism 1 by a certain distance), so that the upper side of the aluminum tube abuts against the lower surface of the pressure roller 4 and the lower side of the pressure rod 3; the electric cylinder 34 is controlled to move the pressure rod 3 back and forth, and at the same time, the cutting machine 5 is controlled to slowly approach the aluminum tube (feed cutting), thereby realizing the circumferential cutting (rotation cutting) of the aluminum tube, effectively avoiding the problem of uneven local stress and deformation of the aluminum tube caused by always cutting in one direction, ensuring cutting quality, and effectively improving the cutting efficiency of the aluminum tube. After the cutting is completed, the cutting machine 5 is reset, and the first telescopic cylinder 22 drives the circumferential rolling support wheels 21 to descend synchronously, so that the aluminum tube is supported on the axial guide mechanism 1 to continue to be transmitted backward. The overall structure is simple, convenient and efficient in operation, and has good practicality.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
