Description

Technical Field

[0001] This invention belongs to the field of metal tube processing technology, and particularly relates to a cutting device for metal tube processing. Background Technology

[0002] Metal pipes are pipes used to transport substances such as liquids, gases, solids, or optical fibers. They are usually made of metal materials, such as steel, stainless steel, and aluminum. Metal pipes have excellent strength and corrosion resistance and are widely used in various industrial fields and daily life.

[0003] Metal pipes come in various shapes, among which Y-shaped metal pipes resemble the letter "Y" in appearance. They typically have a central main pipe and a branch pipe, forming a "Y" structure. When using Y-shaped pipes, to ensure the ends fit snugly against the sidewalls of storage tanks containing liquids or gases, and to facilitate welding and fixing at the contact points, the ends of the Y-shaped pipe usually need to be cut. This ensures the length and cross-section of the Y-shaped pipe match the sidewalls of the storage tank. However, in current technology, the cutting of Y-shaped pipe ends is generally done by hand by workers using cutting and grinding tools. The machine cuts the Y-shaped tubes to match the curvature and length of both ends of the tube to the storage tank. However, when the Y-shaped tubes are cut manually, errors in the curvature of the cut ends are prone to occur, resulting in gaps at the contact points between the ends of the Y-shaped tube and the side wall of the storage tank. This affects the welding effect, reduces the quality of the cut, and the manual cutting speed is slow, affecting the cutting efficiency. In addition, after the Y-shaped tubes are cut, they need to be manually polished using a cutting and polishing machine, which is inefficient and greatly affects the efficiency of polishing the Y-shaped tubes.

[0018] 3. The wall thickness detection component can adjust the rotation speed of the cutting and grinding machine according to the wall thickness of the Y-shaped tube, which facilitates more stable cutting of the Y-shaped tube, ensures a smooth cut at the end of the Y-shaped tube, and allows the Y-shaped tube to fit better against the side wall of the storage tank, thereby improving the cutting quality and stability of the device.

[0036] Specifically, it enables the curvature of the cut ends of the Y-shaped tube to match the outer wall of the storage tank, facilitating subsequent welding and fixing of the Y-shaped tube to the outer wall of the storage tank.

The side wall of the conductive plate 1612 and the variable resistance surface of the resistance plate 1610 are located on the same plane.

[0039] Specifically, the rotation speed of the cutting and grinding machine 13 can be adjusted according to the wall thickness of the Y-shaped tube, which facilitates more stable cutting of the Y-shaped tube, ensures a smooth end when cutting the Y-shaped tube, and allows the Y-shaped tube to better fit the side wall of the storage tank, thereby improving the cutting quality and stability of the device.

[0040] The operating principle of the present invention is now described as follows:

[0041] In this invention, when it is necessary to cut the Y-shaped metal tube, firstly, the second motor 151 is started, driving the bidirectional screw 153 to rotate, causing the two moving blocks 154 connected by the threaded wall of the bidirectional screw 153 to move, driving the two first fixing rings 156 to move to positions matching the two ends of the main body of the Y-shaped metal tube. Then, the Y-shaped metal tube to be cut is placed directly above the fifth groove 161, so that the intersection of the main body and the branch tube is located in the middle of the two moving blocks 154. Then, the fourth electric telescopic rod 155 is started, causing the first fixing rings 156 to move to both sides of the main body of the Y-shaped tube. Then, the second electric telescopic rod 155 is started. The fifth electric telescopic rod 157 is activated, causing the first clamping plate 158 to move and fix the outer wall of the Y-shaped main pipe. Then, the sixth electric telescopic rod 1510 is activated, causing the two second fixing rings 1512 to move to both sides of the main pipe. Next, the seventh electric telescopic rod 1513 is activated, causing the second clamping plate 1514 to move and fix the middle position of the main pipe. Then, the fourth motor 179 is activated, causing the round rod 1710 to rotate, so that the third fixing ring 1711 rotates to an angle that matches the branch pipe. Finally, the second electric slide rail 177 is activated. The third motor 171 is then activated, causing the outer casing 178 to move and position the third fixing ring 171 at the end of the branch pipe. The third motor 171 is then activated, rotating the threaded screw 173, which moves the fixing plate 174 and the third fixing ring 1711 to a position matching the branch pipe. Next, the eighth electric telescopic rod 175 is activated, moving the third fixing ring 1711 to both sides of the branch pipe. Then, the ninth electric telescopic rod 1712 is activated, moving the third clamping plate 1713 to fix the outer wall of the branch pipe. Finally, the third electric telescopic rod 12 is activated, moving the cutting and grinding machine 13. The cutting and grinding machine 13 is moved so that its blade is positioned on one side of the Y-shaped tube. Then, the first motor 7 and the cutting and grinding machine 13 are started, causing the cutting and grinding machine 13 to rotate around the first motor 7. At the same time, the upper two ends of the Y-shaped tube are cut, so that the arc produced at the cut ends of the upper two ends of the Y-shaped tube matches the outer wall of the storage tank. This facilitates the subsequent welding and fixing of the Y-shaped tube to the outer wall of the storage tank. Furthermore, by fixing the Y-shaped tube, it is prevented that the arc of the upper two ends of the Y-shaped tube will be incorrect after cutting due to shaking during the cutting process. This avoids manual cutting and improves the efficiency and effectiveness of the device in cutting Y-shaped tubes.

[0042] Before cutting the Y-shaped tube, the first electric slide rail 3 is started, which moves the mounting plate 6 and changes the position of the first motor 7. This changes the center of rotation of the cutting and grinding machine 13, thereby changing the curvature of the ends of the Y-shaped tube when cutting. At the same time, by controlling the extension and retraction of the second electric telescopic rod 10, the connecting plate 11 moves the third electric telescopic rod 12. This ensures that the cutting and grinding machine 13 can cut the Y-shaped tube to the same length as the design length. The center of rotation of the cutting and grinding machine 13 can be adjusted according to the curvature of the ends of the Y-shaped tube to ensure that the curvature of the cut ends matches the outer wall of the storage tank. The position of the cutting and grinding machine 13 can also be adjusted according to the required length of the Y-shaped tube, thereby achieving precise cutting of the Y-shaped tube and improving the reliability of the device.

[0043] Before cutting the Y-shaped tube using the cutting and grinding machine 13, the tenth electric telescopic rod 162 is activated, causing the L-shaped plate 163 to move upward, allowing the first baffle 166 to enter the main pipe. Then, the eleventh and twelfth electric telescopic rods 165 and 167 are activated, causing the first baffle 166 and second baffle 168 to move towards the side wall of the main pipe and contact it. During the movement of the first baffle 166 and second baffle 168, the resistance plate 1610 and conductive plate 1612 will move towards opposite ends. Because a certain distance is formed between the resistance plate 1610 and the conductive plate 1612... A sliding rheostat is used. As the resistance plate 1610 contacts the conductive plate 1612, the resistance of the resistance plate 1610 will continuously change. The greater the distance it moves, the smaller the wall thickness of the main pipe. At this time, the resistance of the resistance plate 1610 is greater, the current is smaller, and the speed of the cutting and grinding machine 13 is reduced. The speed of the cutting and grinding machine 13 can be changed according to the wall thickness of the Y-shaped tube, which facilitates more stable cutting of the Y-shaped tube, ensures a smooth end when cutting the Y-shaped tube, and allows the Y-shaped tube to fit better with the side wall of the storage tank, thereby improving the cutting quality and stability of the device.

[0044] After the Y-shaped tube is cut, the cutting and polishing machine 13 is controlled according to the above steps to continue polishing the cut part of the Y-shaped tube. This makes it easier for the Y-shaped tube to fit completely with the side wall of the storage tube. This avoids the need for workers to continue polishing the cut part of the Y-shaped tube by hand after cutting it, and greatly increases the efficiency of polishing the Y-shaped tube.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
