Description

Technical Field

[0001] This utility model relates to the field of steel pipe cutting technology, specifically to a stainless steel pipe cutting device that facilitates fixed-length cutting. Background Technology

[0002] Stainless steel pipes are hollow tubular profiles made from stainless steel through processes such as extrusion, welding, or seamless rolling. With their high strength, excellent corrosion resistance (resistance to acid, alkali, and humid environments), good heat resistance, and smooth surface, they are widely used in building water supply and drainage, chemical transportation, medical devices, automotive parts, and decoration projects. Depending on the application scenario, stainless steel pipes need to be cut to a fixed length.

[0003] Currently, in the fixed-length cutting of stainless steel pipes, the cutting points are still commonly marked manually using a tape measure or measuring tape. This process is cumbersome and time-consuming. In addition, manual operation is susceptible to factors such as hand tremors, visual deviations, and errors in measuring tool readings, which may cause deviations between the marked position and the actual required length, thereby affecting the subsequent cutting accuracy and increasing the risk of pipe loss. Therefore, we propose a stainless steel pipe cutting device that facilitates fixed-length cutting. Utility Model Content

[0004] The purpose of this invention is to provide a stainless steel pipe cutting device that facilitates fixed-length cutting. This device allows for easy fixed-length cutting of stainless steel pipes without the need for manual measurement and marking, thus improving cutting efficiency and accuracy. It solves the problem that current fixed-length cutting operations for stainless steel pipes still commonly rely on manual measurement using tape measures or measuring tapes to mark cutting points on the pipes. This process is cumbersome and time-consuming. Furthermore, manual operation is susceptible to factors such as hand tremors, visual biases, and errors in measuring tool readings, which can lead to deviations between the marked position and the actual required length, affecting subsequent cutting accuracy and increasing the risk of pipe wastage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stainless steel pipe cutting device for easy fixed-length cutting, comprising a U-shaped frame, wherein several rotating rollers are equidistantly mounted on both sides of the inner surface of the upper surface of the U-shaped frame, and each rotating roller has an annular groove on its outer surface; a fixed frame is fixedly mounted on the upper surface of the U-shaped frame, and an electric cylinder is fixedly mounted on the upper surface of the fixed frame; a lifting plate is fixedly connected to the output end of the electric cylinder; sliding sleeves are symmetrically fixedly mounted on both sides of the upper surface of the lifting plate; sliding rods are slidably inserted into the two sliding sleeves; a cutting disc is provided between the two sliding rods; a helical spring is wound around the outer surface of the two sliding rods; a wheel frame is fixedly mounted at the bottom end of the two sliding rods; a pressure roller is rotatably mounted inside the two wheel frames via a wheel axle; and a rotating motor and a meter counter are fixedly mounted on the front surface of the two wheel frames respectively.

[0006] Preferably, the ends of the two axles are fixedly connected to the output end of the rotating motor and the input end of the meter counter, respectively.

[0007] Preferably, a limit block is fixedly connected to the top of each of the two slide rods.

[0008] Preferably, a cutting motor is fixedly installed on the lower surface of the lifting plate.

[0009] Preferably, the inner wall of the fixed frame is provided with a sliding groove near the front and rear surfaces, and the lifting plate is fixedly installed with sliders on the front and rear surfaces, with the two sliders located inside the two sliding grooves respectively.

[0010] Preferably, a display screen and a switch panel are fixedly mounted on the front surface of the mounting bracket.

[0011] Preferably, a base plate is fixedly installed on the lower surface of the U-shaped frame, and bolt holes are provided on the upper surface of the base plate near the four corners.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model, by setting up a U-shaped frame, rotating roller, annular groove, fixed frame, electric cylinder, lifting plate, cutting disc, sliding sleeve, sliding rod, helical spring, wheel frame, pressure roller, meter counter, and rotating motor, achieves convenient fixed-length cutting of stainless steel tubes without the need for manual measurement and marking, thus improving cutting efficiency and accuracy. The stainless steel tube is placed on the rotating roller inside the U-shaped frame, with part of the stainless steel tube located inside the annular groove, which acts as a limit for the stainless steel tube. When the stainless steel tube moves to below the first pressure roller, i.e., the pressure roller driven by the rotating motor, the output end of the electric cylinder drives the lifting plate to descend, thus compressing the helical spring so that the first pressure roller can press down on the stainless steel tube. On the upper surface of the steel pipe, a rotating motor drives the first pressure roller to rotate, so that the pressure roller can move the stainless steel pipe towards the second pressure roller. When the end of the stainless steel pipe contacts the second pressure roller, the length measurement begins. As the stainless steel pipe moves under the second pressure roller, it drives the second pressure roller to rotate, and the length of the stainless steel pipe passing under the cutting disc can be measured by the meter counter. When the required cutting length is reached, the rotating motor stops working, the electric cylinder continues to drive the lifting plate to descend, and at the same time the helical spring is further compressed, pressing and fixing the stainless steel pipe through the two pressure rollers. After the cutting disc descends and contacts the stainless steel pipe, the fixed-length cutting of the stainless steel pipe is completed.

[0014] 2. By setting up a sliding groove and a slider, this utility model guides the lifting of the lifting plate, which helps to improve the stability of the lifting plate and also improves the accuracy of the fixed-length cutting of stainless steel pipes. Attached Figure Description

[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figures 1-4 As shown, the present invention proposes a stainless steel pipe cutting device for easy fixed-length cutting, comprising a U-shaped frame 2, wherein several rotating rollers 7 are equidistantly mounted on both sides of the inner surface of the upper surface of the U-shaped frame 2, and each rotating roller 7 has an annular groove 8 on its outer surface. A fixing frame 3 is fixedly mounted on the upper surface of the U-shaped frame 2, and the fixing frame 3 is shaped like an "n" when viewed from the side. An electric cylinder 6 is fixedly mounted on the upper surface of the fixing frame 3, and a lifting plate 5 is fixedly connected to the output end of the electric cylinder 6. Sliding sleeves 17 are symmetrically fixedly mounted on both sides of the upper surface of the lifting plate 5. Sliding rods 18 are slidably inserted into the two sliding sleeves 17. Limiting blocks 19 are fixedly connected to the top of the two sliding rods 18, and the limiting blocks 19 limit the sliding rods 18 to prevent them from slipping out of the sliding sleeves 17. A cutting disc 12 is arranged between the two sliding rods 18. A cutting motor 10 is fixedly mounted on the lower surface of the lifting plate 5, and the cutting motor 10 drives the cutting disc 12 to rotate.

[0022] Both sliding rods 18 have helical springs 16 wound around their outer surfaces. Wheel frames 15 are fixedly installed at the bottom of both sliding rods 18. Pressure rollers 14 are rotatably mounted inside each wheel frame 15 via axles. A rotating motor 11 and a meter counter 13 are fixedly installed on the front surfaces of the two wheel frames 15, respectively. The ends of the two axles are fixedly connected to the output end of the rotating motor 11 and the input end of the meter counter 13, respectively. Slide grooves 4 are provided on the inner wall of the fixed frame 3 near the front and rear surfaces. Sliding blocks 9 are fixedly installed on the front and rear surfaces of the lifting plate 5, with the two sliding blocks 9 located inside the two slide grooves 4, respectively. The front surface of the fixed frame 3... A display screen 21 and a switch panel 20 are fixedly installed. The display screen 21 is electrically connected to the meter counter 13 and is used to display the length value of the stainless steel tube measured by the meter counter 13. The switch panel 20 is equipped with three control switches, which are electrically connected to and control the electric cylinder 6, the cutting motor 10 and the rotating motor 11 respectively. The slide 4 and the slider 9 guide the lifting plate 5, which helps to improve the stability of the lifting plate 5 and also improves the accuracy of the fixed length cutting of the stainless steel tube. A base plate 1 is fixedly installed on the lower surface of the U-shaped frame 2, and bolt holes are provided on the upper surface of the base plate 1 near the four corners.

[0023] In use, the stainless steel tube is placed on the rotating roller 7 inside the U-shaped frame 2, with part of the stainless steel tube located inside the annular groove 8, which serves to limit the movement of the stainless steel tube. When the stainless steel tube moves below the first pressure roller 14, i.e., the pressure roller 14 is driven by the rotating motor 11, the output end of the electric cylinder 6 drives the lifting plate 5 to descend, compressing the helical spring 16 so that the first pressure roller 14 can press against the upper surface of the stainless steel tube. The rotating motor 11 drives the first pressure roller 14 to rotate, so that the pressure roller 14 can move the stainless steel tube towards the second pressure roller 14. When the stainless steel... After the end of the tube contacts the second pressure roller 14, length measurement begins. As the stainless steel tube moves below the second pressure roller 14, it drives the second pressure roller 14 to rotate. The length of the stainless steel tube passing under the cutting disc 12 can be measured by the meter counter 13. When the required cutting length is reached, the rotating motor 11 stops working, the electric cylinder 6 continues to drive the lifting plate 5 to descend, and the spiral spring 16 is further compressed. The stainless steel tube is pressed and fixed by the two pressure rollers 14. After the cutting disc 12 descends and contacts the stainless steel tube, the fixed-length cutting of the stainless steel tube is completed.
