Description
Technical Field
[0001] This invention relates to the field of aluminum alloy cutting equipment technology, specifically to a cutting device for aluminum alloy tubes that is easy to clamp. Background Technology
[0002] Aluminum alloys are one of the most widely used non-ferrous metal structural materials in industry. They are widely used in aviation, aerospace, automotive, machinery manufacturing, shipbuilding and chemical industries. Aluminum alloys have low density but high strength, which is close to or exceeds that of high-quality steel. They also have good plasticity and excellent electrical conductivity, thermal conductivity and corrosion resistance. Therefore, they are widely used in industry, second only to steel in terms of usage. Aluminum alloy tubes are one of the commonly used aluminum alloy materials. After the processing and manufacturing of aluminum alloy tubes, slitting is often involved, and the aluminum alloy tubes need to be clamped and fixed during slitting.
[0003] Publication No. CN219188823U discloses an aluminum alloy tube cutting device. Multiple sets of aluminum alloy tubes are placed in the lower tube grooves evenly distributed at the top of a support base. A rotating screw drives a lifting plate to descend, which in turn lowers a pressure rod and an arc-shaped pressure plate until the arc-shaped pressure plate stably limits the aluminum alloy tubes. This allows the cutting device to stably limit the size and specifications of aluminum alloy tubes, ensuring their stability and thus cutting accuracy. Furthermore, a motor drives a first lead screw to rotate, causing the threaded block on the lead screw to move longitudinally with the cutting motor, achieving cutting during this movement. This allows for continuous cutting of multiple sets of aluminum alloy tubes, improving cutting efficiency. However, this patent still has the following problems in practical use:
[0004] Although this aluminum alloy tube cutting device uses a lifting plate to lower the pressure bar and arc-shaped pressure plate until the arc-shaped pressure plate stably limits the aluminum alloy tube, thus enabling the device to stably limit aluminum alloy tubes of different sizes, not all aluminum alloy tubes are round. There are also square, oval, and triangular tubes and other irregular shapes. This device can only clamp and fix round tubes, and is not convenient for fixing square, oval, and triangular tubes, thus limiting its applicability. When compressing longer pipes, it is inconvenient to fix the two sides immediately adjacent to the cut. As a result, if the cutting is not completed, part of the pipe may break while the other part remains connected. Under the influence of the pipe's gravity, the center of gravity of the pipe may shift, causing the cut end to bend and deform. This affects the smoothness of the cut and is not conducive to subsequent splicing and welding operations. At the same time, a certain amount of aluminum powder is generated when cutting aluminum alloy pipes. When the aluminum powder reaches a certain concentration, it may come into contact with sparks generated during cutting, resulting in an explosion, which is detrimental to the safety of cutting.
[0005] Therefore, a cutting device for aluminum alloy tubes that is easy to clamp is proposed to solve the problems mentioned above. Summary of the Invention
[0006] The purpose of this invention is to provide a cutting device for aluminum alloy tubes that facilitates clamping, thereby solving the problems mentioned in the background art, such as the inconvenience in fixing irregularly shaped tubes like square, elliptical, and triangular aluminum tubes, the limited applicability, and the difficulty in fixing the two sides adjacent to the cut when clamping long tubes. This leads to a situation where, before the cutting is completed, part of the tube has broken while the other part remains connected, causing the tube's center of gravity to shift under the influence of gravity, resulting in bending and deformation of the cut end, affecting the smoothness of the cut, and hindering subsequent splicing and welding operations. Furthermore, the cutting of aluminum alloy tubes generates a certain amount of aluminum powder, which, when it reaches a certain concentration, can come into contact with sparks generated during cutting, potentially causing an explosion, thus compromising cutting safety.

[0021] Compared with the prior art, the beneficial effects of this invention are: This easy-to-clamp aluminum alloy tube cutting device utilizes a vertical clamping plate to clamp and fix square tubes, a clamping rotating plate to clamp triangular tubes, and an arc-shaped clamping plate to clamp and fix round tubes, thus adapting to tubes of various shapes and improving the applicability of the clamping and cutting mechanism. The surface of the protective rotating plate is provided with anti-slip rubber to prevent the tube from shaking due to shearing force during cutting, thereby affecting the flatness of the cut. Furthermore, when splicing and welding two tubes... The cutting process has a certain impact on the weld. The top clamping plate and protective rotating plate clamp and fix both sides of the pipe cut to prevent the pipe's center of gravity from shifting due to the cutting process when the pipe length is long. This prevents the pipe cut from bending and deforming under gravity, thus affecting the flatness of the cut. A spiral baffle isolates the sparks generated during cutting, and a vacuum cleaner uses suction to collect the aluminum powder generated during cutting through a rotating absorption cylinder into a dust collection box. This prevents excessive aluminum powder concentration from contacting sparks and causing an explosion, thus improving the safety of aluminum alloy pipe cutting. The specific details are as follows:
[0022] 1. By setting up a clamping and cutting mechanism, not only can the threaded rod protective cover protect the adjusting double-sided threaded rod, preventing cutting dust from entering the interior of the adjusting double-sided threaded rod and affecting the transmission between the adjusting double-sided threaded rod and the adjusting threaded sleeve, but also, by placing the aluminum alloy tube to be cut on the clamping bracket, and by squeezing the clamping bracket and rotating the clamping rotating rod, the two clamping sliding sleeves slide relative to each other on the outside of the clamping sliding rod, while simultaneously driving the two clamping sliding plates to move closer together. The vertical clamping plate can clamp and fix the square tube, utilizing the elastic force of the connecting spring. The mechanism functions by bringing the two vertical clamping plates closer together. Under the action of the top rotating rod, the clamping rotating plate and the arc-shaped clamping plate rotate. Utilizing the elastic force of the internal compression springs of the clamping rotating frame, the distance between the vertical clamping plates and the clamping rotating plate can be adjusted. The clamping rotating plate can clamp triangular tubes, while the arc-shaped clamping plate can clamp and fix round tubes, thus adapting to various tube shapes and increasing the applicability of the clamping and cutting mechanism. The multi-stage lifting cylinder lowers the lifting and fixing plate, and the rotating motor drives the rotating worm gear to rotate. The meshing connection between the rod and the rotating worm gear allows the worm gear to drive the electric telescopic rod and the cutting machine body to rotate, adjusting the horizontal angle of the cutting machine body for cutting aluminum alloy tubes at different angles. The electric telescopic rod enables the lifting and lowering adjustment of the cutting machine body, facilitating the cutting of aluminum alloy tubes. A multi-stage lifting cylinder enables the lifting and lowering of the clamping bracket. When the top of the tube contacts the top pressure plate, the rotation of the top limiting rotating rod causes the limiting sliding sleeve to slide outside the limiting sliding rod, simultaneously pulling the two top clamping plates closer together. The top clamping plates then... The top of the aluminum alloy tube is clamped, and the rotation of the protective rotating plate is achieved by the elastic force of the first spring assembly. The surface of the protective rotating plate is provided with anti-slip rubber, which can prevent the tube from shaking due to the shearing force during cutting, thus affecting the flatness of the cut. At the same time, it can also affect the weld when splicing and welding two tubes. The top clamping plate and the protective rotating plate clamp and fix the two sides of the tube cut, so as to prevent the tube's center of gravity from shifting due to cutting when the tube is long. Under the action of gravity, the tube cut will bend and deform, thus affecting the flatness of the cut.
[0023] 2. By setting up a dust extraction and protection component, the adjustable motor can drive the adjusting bidirectional threaded rod to rotate, causing the adjusting threaded sleeve to move relative to the clamping base. This allows for adjustment of the clamping position according to the length of the pipe, thereby improving the stability of pipe cutting. When cutting a long pipe, the second hinge rotates the unfolded support plate to a horizontal position, while the support block supports the unfolded support plate. By rotating the adjusting knob, the supporting bidirectional threaded rod rotates, causing the two supporting threaded sleeves to move relative to each other on the outside of the supporting bidirectional threaded rod, while simultaneously driving the supporting rotating rod to rotate. This allows for height adjustment of the second support plate, facilitating pipe support and improving the stability of pipe cutting. During pipe cutting, the rotary motor is started to drive the rotary absorption cylinder to rotate. The spiral baffle isolates the sparks generated during cutting, and the vacuum cleaner generates suction to collect the aluminum powder generated during cutting through the rotary absorption cylinder into the dust collection box. This prevents excessive aluminum powder concentration from contacting sparks and causing an explosion, thus improving the safety of aluminum alloy pipe cutting. Attached Figure Description

A pressing spring 117 is fixedly installed on one side of the pressing sliding sleeve 116. The pressing sliding sleeve 116 is rotatably connected to the top rotating rod 111. The threaded rod protective cover 101 protects the adjusting bidirectional threaded rod 206 to prevent the dust generated during cutting from entering the interior of the adjusting bidirectional threaded rod 206, thereby affecting the transmission between the adjusting bidirectional threaded rod 206 and the adjusting threaded sleeve 207. By placing the aluminum alloy tube to be cut on the clamping bracket 106, and by squeezing the clamping bracket 106 and under the rotation of the clamping rotating rod 103, the two clamping sliding sleeves 104 slide relative to each other on the outer side of the clamping sliding rod 105. Simultaneously, the two clamping sliding plates 108 are brought closer together. The vertical clamping plate 110 can clamp and fix the square tube. With the elastic force of the connecting spring 109, when the two vertical clamping plates 110 are brought closer together, the top rotating rod 111 causes the clamping rotating plate 113 and the arc-shaped clamping plate 114 to rotate. With the elastic force of the internal compression spring 117 of the clamping rotating frame 112, the distance between the vertical clamping plate 110 and the clamping rotating plate 113 can be adjusted. The clamping rotating plate 113 can clamp the triangular tube, while the arc-shaped clamping plate 114 can clamp and fix the round tube, thus adapting to tubes of various shapes and improving the applicability of the clamping and cutting mechanism 1.

An electric telescopic rod 125 is fixedly installed at the bottom of the rotating worm wheel 124. The bottom of the telescopic rod 125 is fixedly installed with the cutting machine body 126. By activating the multi-stage lifting cylinder 118, the lifting fixed plate 119 is driven to descend. The rotating motor 122 drives the rotating worm gear 123 to rotate. Utilizing the meshing connection between the rotating worm gear 123 and the rotating worm wheel 124, the rotating worm wheel 124 drives the electric telescopic rod 125 and the cutting machine body 126 to rotate.

The multi-stage lifting cylinder 118 can... The clamping bracket 128 is raised and lowered. When the top of the pipe contacts the top pressure plate 132, the rotation of the top limiting rotating rod 129 causes the limiting sliding sleeve 130 to slide outside the limiting sliding rod 131, while simultaneously driving the two top clamping plates 134 to move closer to each other. The top clamping plates 134 can clamp the top of the aluminum alloy pipe. The elastic force of the first spring assembly 137 can realize the rotation of the protective rotating plate 136.

[0042] Working principle: Before using this easy-to-clamp aluminum alloy tube cutting device, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 11 As shown, firstly, the adjusting bidirectional threaded rod 206 is protected by the threaded rod protective cover 101 to prevent cutting dust from entering the interior of the adjusting bidirectional threaded rod 206, thereby affecting the transmission between the adjusting bidirectional threaded rod 206 and the adjusting threaded sleeve 207. The aluminum alloy tube to be cut is placed on the clamping bracket 106. By squeezing the clamping bracket 106 and rotating the clamping rotating rod 103, the two clamping sliding sleeves 104 slide relative to each other on the outside of the clamping sliding rod 105, while simultaneously driving the two clamping sliding plates 108 to move closer together. The vertical clamping plate 110 can then clamp the square tube. For clamping and fixing, the elastic force of the connecting spring 109 is used to bring the two vertical clamping plates 110 closer together. Under the action of the top rotating rod 111, the clamping rotating plate 113 and the arc-shaped clamping plate 114 are rotated. The elastic force of the internal compression spring 117 of the clamping rotating frame 112 can be used to adjust the distance between the vertical clamping plate 110 and the clamping rotating plate 113. The clamping rotating plate 113 can clamp triangular tubes, while the arc-shaped clamping plate 114 can clamp and fix circular tubes, thus adapting to tubes of various shapes and improving the applicability of the clamping and cutting mechanism 1.
[0043] Secondly, by activating the multi-stage lifting cylinder 118, the lifting fixed plate 119 is lowered. The rotating motor 122 drives the rotating worm gear 123 to rotate. Utilizing the meshing connection between the rotating worm gear 123 and the rotating worm wheel 124, the rotating worm wheel 124 drives the electric telescopic rod 125 and the cutting machine body 126 to rotate. This allows adjustment of the horizontal angle of the cutting machine body 126, facilitating cutting aluminum alloy pipes at different angles. The electric telescopic rod 125 enables the lifting and lowering adjustment of the cutting machine body 126, facilitating the cutting of aluminum alloy pipes. The multi-stage lifting cylinder 118 enables the lifting and lowering movement of the clamping bracket 128. When the top of the pipe contacts the top pressure plate 132, the rotation of the top limiting rotating rod 129 causes the limiting sliding sleeve 130 to... While the limiting sliding rod 131 slides on the outside, it drives the two top clamping plates 134 to move closer to each other. The top clamping plates 134 can clamp the top of the aluminum alloy tube. The elastic force of the first spring assembly 137 can realize the rotation of the protective rotating plate 136. The surface of the protective rotating plate 136 is provided with anti-slip rubber, which can prevent the tube from shaking due to the shearing force during cutting, thereby affecting the flatness of the cut. At the same time, when splicing and welding two tubes, it will have a certain impact on the weld. The top clamping plates 134 and the protective rotating plate 136 clamp and fix the two sides of the tube cut, so as to prevent the tube's center of gravity from shifting due to cutting when the tube is long. Under the action of gravity, the tube cut will bend and deform, thus affecting the flatness of the cut.
[0044] Finally, the adjusting motor 205 drives the adjusting bidirectional threaded rod 206 to rotate, causing the adjusting threaded sleeve 207 to move relative to the clamping base 102. This allows for adjustment of the clamping position according to the length of the pipe, thereby improving the stability of pipe cutting. When the pipe being cut is long, the unfolding support plate 209 is rotated to a horizontal position under the action of the second hinge 208. At the same time, the support block 204 supports the unfolding support plate 209. By rotating the adjusting knob 211, the supporting bidirectional threaded rod 212 is rotated, causing the two supporting threaded sleeves 213 to be positioned outside the supporting bidirectional threaded rod 212. While moving relative to each other, the supporting rotating rod 214 is driven to rotate, which enables the height adjustment of the second supporting plate 215, making it easier to support the pipe and improve the stability of pipe cutting. When cutting the pipe, the rotary motor 218 is started to drive the rotary absorption cylinder 219 to rotate. The spiral baffle 220 is used to isolate the sparks generated by cutting, and the vacuum cleaner 223 generates suction to make the aluminum powder generated by cutting enter the dust collection box 221 through the rotary absorption cylinder 219 for collection. This avoids the phenomenon of excessive aluminum powder concentration coming into contact with sparks and causing an explosion, thus improving the safety of aluminum alloy pipe cutting.
