Technical Field
[0001] This utility model relates to the field of stainless steel pipe production, specifically a high-precision positioning and cutting device for stainless steel pipes. Background Technology
[0002] Stainless steel pipes are tubular products made from stainless steel material through extrusion, rolling, welding, or seamless forming processes. They possess the basic structural characteristics of metal pipes, and their core advantages lie in their excellent corrosion resistance, good mechanical strength, and high temperature resistance. They can be used stably in complex environments such as humidity, acidity, and alkali, and their smooth surface makes them easy to clean. Stainless steel pipes are widely used in building water supply and drainage, chemical fluid transportation, food and pharmaceutical pipelines, mechanical structural support, and other fields, and are key components in industrial production and public works projects.
[0003] When stainless steel pipes are positioned and cut, the pipes are transported to the feeding track of the cutting equipment. The guide rollers are used to initially position the pipes. The pneumatic or hydraulic clamping mechanism is used to firmly clamp the pipes radially or axially. The cutting parameters are set in the control system. The cutting mechanism cuts the pipes according to the preset trajectory. After the cutting is completed, the pipes are transported to the next process.
[0004] When cutting tubes, relying on markings or measuring tapes can lead to significant length errors and precision defects.
[0005] Therefore, a high-precision positioning and cutting device for stainless steel pipes is proposed to address the above problems. Utility Model Content
[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

A cutting assembly is installed on one side of the frame; a second clamp is installed on the top of the support plate; the second clamp is at the same horizontal height as the first clamp; a stepper motor is installed on one side of the gantry frame; a positioning plate is fixed to the output end of the stepper motor; the cooperation of the servo motor and the ball screw can increase the accuracy of the gantry frame movement, thereby increasing the cutting precision. Setting ball screws on both sides of the cutting table can reduce the contact between the cutting debris and the ball screw, which would reduce the precision. The support plate can provide additional support points, reduce the pressure on the connecting block, and reduce the risk of breakage. One end of the stainless steel tube contacts one side of the tail plate, and the other end contacts the positioning plate, and then it is clamped. This can reduce the number of times the stainless steel tube is positioned when the cutting assembly is cutting, thereby increasing the cutting efficiency.
[0008] Preferably, a connecting pipe is fixedly connected to one side of the gantry frame; a filter screen is installed in the middle of the connecting pipe; a universal joint is fixedly connected to one side of the gantry frame; the universal joint is connected to the connecting pipe through the gantry frame; an atomizing nozzle is fixedly connected to the end of the universal joint; the angle of the atomizing nozzle is adjusted by the universal joint to align it with the cutting area of the cutting assembly, thereby reducing the decrease in hardness and accelerated edge wear of the blade due to local overheating, increasing the quality of the cutting surface, and the atomizing nozzle converts the water flow into water mist, which can continuously cool the cutting area, reduce the cracks caused by the drastic alternation of hot and cold on the blade, extend the blade replacement cycle, and reduce consumable costs.
[0009] Preferably, a set of rubber rings are fixedly connected to both sides of the cutting table; the rubber rings are correspondingly arranged to the ends of the ball screw; an oil-absorbing sponge is fixedly connected to one side of the rubber ring; the oil-absorbing sponge stores lubricating oil, and when the nut end of the ball screw drives the connecting block to move to the end of its stroke, it squeezes the oil-absorbing sponge, so that the lubricating oil is squeezed out and applied to the surface of the ball screw. This can reduce the friction of the ball screw during rotation, improve its transmission efficiency and service life, increase the stability and accuracy of operation, and the buffering effect of the rubber rings can reduce the wear and deformation caused by the collision between the connecting block and components such as the cutting table, reduce the replacement frequency of parts, and improve production efficiency.
[0010] Preferably, a set of rollers is rotatably connected to the bottom of the support plate; the rollers are in contact with the top of the cutting table; by setting rollers between the support plate and the cutting table, the friction between the two can be reduced, the instability such as jamming and shaking can be reduced, the movement stability and accuracy can be increased, the positions of the first clamp and the second clamp can be kept horizontal, and the perpendicularity of the cutting surface can be increased.
[0011] Preferably, baffles are fixed to both sides of the support plate; the baffles are arranged in contact with the top of the cutting table; the baffles direct the debris to a specific location, reducing the amount of debris entering the bottom of the support plate, thereby reducing the wear of the components, reducing the frequency and cost of maintenance and replacement of components, and at the same time, directing the cutting debris to a specific location for easy centralized cleaning of the debris.
[0012] Preferably, a set of brush strips is fixedly connected to both sides of the cutting table; the brush strips are correspondingly arranged to the ball screw; the brush strips are arranged in opposite directions; by intercepting external dust, cutting debris and other impurities from adhering to the surface of the ball screw or entering its transmission gap, the cleanliness of the ball screw's operating environment can be increased, the transmission accuracy can be kept stable, and the processing quality can be improved. The bristles of the brush strips are relatively soft, so they do not interfere with the movement of the connecting block while intercepting impurities, thus increasing practicality.
[0013] The advantages of this utility model are: 1. The high-precision positioning and cutting device for stainless steel pipes described in this utility model can increase the accuracy of gantry movement through the cooperation of servo motor and ball screw, thereby increasing cutting accuracy. The ball screws on both sides of the cutting table can reduce the contact between the cutting debris and the pipe, thus reducing the accuracy reduction. The support plate can provide additional support points, reduce the pressure on the connecting block, and reduce the risk of breakage. One end of the stainless steel pipe contacts one side of the tail plate, and the other end contacts the positioning plate, and then it is clamped. This can reduce the number of positioning steps of the stainless steel pipe during cutting by the cutting component and increase cutting efficiency.
[0014] 2. The high-precision positioning and cutting device for stainless steel pipes described in this utility model adjusts the angle of the atomizing nozzle through a universal joint, aligning it with the cutting area of the cutting component. This reduces the decrease in hardness and accelerated wear of the cutting edge caused by local overheating of the blade, increases the quality of the cut surface, and continuously cools the cutting area after the atomizing nozzle converts the water flow into water mist. This reduces cracks caused by drastic temperature changes in the blade, extends the blade replacement cycle, and reduces consumable costs. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0019] Specific implementation examples are given below.
[0020] like Figures 1 to 4As shown in the figure, a high-precision positioning and cutting device for stainless steel pipes according to an embodiment of the present invention includes a cutting table 1; a tail plate 11 is fixedly connected to the top of the cutting table 1; the tail plate 11 is disposed at the end of the cutting table 1; a first clamp 12 is installed on the top of the cutting table 1; the first clamp 12 is in contact with the tail plate 11; a set of servo motors 13 is installed on one side of the cutting table 1; a ball screw 14 is fixedly connected to the output end of the servo motor 13; the ball screw 14 is installed on both sides of the cutting table 1; the ball screw 14 is rotatably connected to the cutting table 1; a set of connecting blocks 15 is fixedly connected to the nut end of the ball screw 14; a connecting block 15 is fixedly connected to one side of the connecting block 15. Support block 16; support plate 17 is fixedly connected to the top of support block 16; gantry frame 18 is fixedly connected to the top of support plate 17; cutting assembly 19 is installed on one side of gantry frame 18; second clamp 110 is installed on the top of support plate 17; the second clamp 110 is at the same horizontal height as the first clamp 12; stepper motor 111 is installed on one side of gantry frame 18; positioning plate 112 is fixedly connected to the output end of stepper motor 111; during operation, the servo motor 13 drives the ball screw 14 to rotate, causing the gantry frame 18 to move to the side close to the first clamp 12, and the stainless steel tube passes through the second clamp 110 and the first clamp 12, and connects with the tail plate 11. The system initiates side contact, controlling the first clamp 12 and the second clamp 110 to clamp the stainless steel tube. The second clamp 110 has ball bearings on its contact surface with the stainless steel tube to reduce frictional damage to the tube surface during movement. The servo motor 13 moves the gantry 18 to the other end of the stainless steel tube. The cutting assembly 19 rotates to a specified angle, bringing the positioning plate 112 and the stainless steel tube into a horizontal position. The servo motor 13 then brings one side of the positioning plate 112 into contact with the end of the stainless steel tube for positioning. The cutting assembly 19 is then reset, lifting the positioning plate 112. The servo motor 13 moves the gantry 18 to the desired cutting length, and the cutting assembly 19 performs the cutting. If multiple cuts are required, the gantry 18 needs to be moved to the required number of cuts and the total thickness of the cutter. The cooperation between the servo motor 13 and the ball screw 14 can increase the accuracy of the gantry 18 movement, thereby increasing the cutting precision. Setting the ball screw 14 on both sides of the cutting table 1 can reduce the contact between the cutting debris and the ball screw 14, which would reduce the precision. The support plate 17 can provide additional support points, reduce the pressure on the connecting block 15, and reduce the risk of breakage. One end of the stainless steel tube contacts one side of the tail plate 11, and the other end contacts the positioning plate 112, and then it is clamped. This can reduce the number of times the stainless steel tube is positioned when the cutting component 19 is cutting, thereby increasing the cutting efficiency.
[0021] like Figure 1 , Figure 2 and Figure 5As shown, a connecting pipe 2 is fixedly connected to one side of the gantry frame 18; a filter screen 21 is installed in the middle of the connecting pipe 2; a universal joint 22 is fixedly connected to one side of the gantry frame 18; the universal joint 22 is connected to the connecting pipe 2 through the gantry frame 18; an atomizing nozzle 23 is fixedly connected to the end of the universal joint 22; during operation, the universal joint 22 is moved so that the atomizing nozzle 23 is aligned with the cutting area of the cutting component 19, and then the universal joint 22 maintains its position by utilizing its own characteristics. The end of the connecting pipe 2 is connected to a water pump. When the water pump is turned on, the coolant enters the universal joint 22 through the connecting pipe 2 and then... The water flow is converted into a water mist by the atomizing nozzle 23, which cools the blade of the cutting assembly 19. The filter screen 21 intercepts fine particles in the coolant, reducing the clogging of the atomizing nozzle 23. The angle of the atomizing nozzle 23 is adjusted by the universal joint 22 to align it with the cutting area of the cutting assembly 19, reducing the decrease in hardness and accelerated edge wear of the blade caused by local overheating, and increasing the quality of the cut surface. After the atomizing nozzle 23 converts the water flow into a water mist, it can continuously cool the cutting area, reduce the cracks caused by the drastic temperature changes of the blade, extend the blade replacement cycle, and reduce consumable costs.
[0022] like Figure 3 As shown, a set of rubber rings 3 are fixed to both sides of the cutting table 1; the rubber rings 3 are correspondingly set to the ends of the ball screw 14; an oil-absorbing sponge 31 is fixed to one side of the rubber ring 3; during operation, an appropriate amount of lubricating oil is injected into the surface of the oil-absorbing sponge 31. When the nut end of the ball screw 14 moves to the end of its stroke, the connecting block 15 squeezes out the lubricating oil inside the oil-absorbing sponge 31. When the ball screw 14 rotates, the lubricating oil is applied to its surface. The rubber rings 3 use their own elasticity to reduce direct contact between the connecting block 15 and the cutting table 1, thus buffering the collision. The impact force is absorbed by the oil-absorbing sponge 31, which stores lubricating oil. When the nut end of the ball screw 14 moves the connecting block 15 to the end of its stroke, it squeezes the oil-absorbing sponge 31, causing the lubricating oil to be squeezed out and applied to the surface of the ball screw 14. This reduces the friction of the ball screw 14 during rotation, improves its transmission efficiency and service life, and increases the stability and accuracy of operation. The buffering effect of the rubber ring 3 can reduce the wear and deformation caused by the collision between the connecting block 15 and components such as the cutting table 1, reduce the frequency of component replacement, and improve production efficiency.
[0023] like Figure 4 As shown, a set of rollers 4 are rotatably connected to the bottom of the support plate 17; the rollers 4 are in contact with the top of the cutting table 1; during operation, when the support plate 17 moves, the rollers 4 rotate by the friction between the support plate 17 and the cutting table 1, reducing the friction between the two and reducing wear. By setting the rollers 4 between the support plate 17 and the cutting table 1, the friction between the two can be reduced, reducing unstable phenomena such as jamming and shaking, increasing the stability and accuracy of movement, keeping the first clamp 12 and the second clamp 110 in a horizontal position, and increasing the perpendicularity of the cutting surface.
[0024] like Figure 4 As shown, baffles 5 are fixed to both sides of the support plate 17; the baffles 5 are arranged in contact with the top of the cutting table 1; during operation, when the support plate 17 moves, the baffles 5 direct the cutting debris on the surface of the cutting table 1 to a direction, reducing its entry into the bottom of the support plate 17 and causing wear. By directing the debris to a direction, the debris entering the bottom of the support plate 17 is reduced, thereby reducing the wear of the components and reducing the frequency and cost of maintenance and replacement of components. At the same time, the cutting debris is directed to a designated location, making it easier to clean the debris.
[0025] like Figures 1 to 2 As shown, a set of brush strips 6 are fixedly connected to both sides of the cutting table 1; the brush strips 6 are correspondingly arranged to the ball screw 14; the brush strips 6 are arranged in opposite directions; during operation, the brush strips 6 intercept external dust and impurities from contacting the ball screw 14, while the bristles are soft and do not obstruct the movement of the connecting block 15. By intercepting external dust, cutting debris and other impurities from the ball screw 14 from adhering to its surface or entering its transmission gap, the cleanliness of the operating environment of the ball screw 14 can be increased, the transmission accuracy can be kept stable, and the processing quality can be improved. The bristles of the brush strips 6 are relatively soft, and while intercepting impurities, they do not interfere with the movement of the connecting block 15, thus increasing practicality.
[0026] Working principle: By controlling the servo motor 13 to drive the ball screw 14 to rotate, the gantry 18 moves to the side close to the first clamp 12, allowing the stainless steel tube to pass through the second clamp 110 and the first clamp 12, contacting one side of the tail plate 11. The first clamp 12 and the second clamp 110 are controlled to clamp the stainless steel tube. The contact surface between the second clamp 110 and the stainless steel tube is equipped with balls to reduce frictional damage to the tube surface during movement. The servo motor 13 is controlled to move the gantry 18 to the other end of the stainless steel tube, and the cutting assembly 19 is controlled to rotate at a specified angle. The positioning plate 112 is positioned horizontally with the stainless steel tube. The servo motor 13 is controlled to bring one side of the positioning plate 112 into contact with the end of the stainless steel tube for positioning. The cutting assembly 19 is then reset, raising the positioning plate 112. The servo motor 13 is then controlled to move the gantry 18 to the desired cutting length position. The cutting assembly 19 is then used for cutting. If multiple cuts are required, the gantry 18 is moved to the desired number of cuts and the total blade thickness. The universal joint 22 is then manipulated to align the atomizing nozzle 23 with the cutting area of the cutting assembly 19. The universal joint 22 is then... 2. Utilizing its own characteristics to maintain a fixed position, the end of connecting pipe 2 is connected to a water pump. Turning on the water pump allows coolant to pass through connecting pipe 2 into universal joint 22, then through atomizing nozzle 23, where it is converted into a water mist and sprayed out to cool the cutting blades of the cutting assembly 19. Filter screen 21 intercepts fine particles in the coolant, reducing clogging of atomizing nozzle 23. A suitable amount of lubricating oil is injected onto the surface of the oil-absorbing sponge 31. When the nut end of the ball screw 14 moves to the end of its stroke, connecting block 15 squeezes out the lubricating oil inside the oil-absorbing sponge 31. As the ball screw 14 rotates, the lubricating oil... The rubber ring 3 reduces direct contact between the connecting block 15 and the cutting table 1 by applying the coating to its surface, thus buffering the impact of the collision. When the support plate 17 moves, the roller 4 rotates by the friction between the support plate 17 and the cutting table 1, reducing friction between the two and reducing wear. When the support plate 17 moves, the baffle 5 directs the cutting debris on the surface of the cutting table 1 to a direction, reducing its entry into the bottom of the support plate 17 and causing wear. The brush strip 6 intercepts external dust and impurities from contacting the ball screw 14, while the soft bristles do not obstruct the movement of the connecting block 15.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
