Description

Technical Field

[0001] This utility model relates to the field of pipe cutting technology, and in particular to an automatic length-fixing device for metal pipes. Background Technology

[0002] Metal pipes are tubular materials made of metal. They are a widely used industrial product used to transport fluids (such as water, oil, and gas), transmit mechanical energy (such as hydraulic oil pipelines in hydraulic systems), or serve as structural components (such as steel pipe uprights and crossbars in building scaffolding).

[0003] In the field of mechanical processing, pipe cutting to a fixed length is frequently involved. Currently, the main methods of cutting are manual cutting and CNC cutting. Manual cutting requires manual measurement and marking before using a cutting machine. Since the cutting speed and direction of the cutting machine need to be manually controlled during the cutting process, it is difficult to ensure the stability and consistency of the cutting. This is not only inconvenient to operate and very inefficient, but also results in uneven cut surfaces, excessive burrs, and other quality problems, reducing the precision and quality stability of the product. Moreover, the high-temperature sparks, high-speed rotating blades, and sharp pipe edges generated by the cutting machine pose significant safety hazards to operators. CNC cutting is more precise, but it is less efficient and more expensive. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an automatic length-fixing device for metal pipes.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automatic length-fixing device for metal pipes, comprising a pipe body, the surface of which is provided with multiple drive wheels for driving the pipe body, the drive wheels being symmetrically designed vertically, and each drive wheel being driven by an independent drive motor, one of which has a support base fixed to its circumference, the bottom of which is a base, a sliding column slidably connected to the top of the base, a cutting box fixed to the top of the sliding column, a cutting blade rotatably connected to the side of the cutting box near the drive wheel, the cutting blade being driven by an external motor, a return spring nested on the surface of the sliding column, a slide block provided on the side of the cutting box away from the cutting blade, a length-fixing base slidably connected to the bottom of the slide block, an adjusting groove provided on the surface of the length-fixing base, a slider provided inside the adjusting groove, a rotating rod rotatably connected to one end of the slider, a connecting rod bolted to the top of the rotating rod, and the end of the connecting rod near the slide block extending to the surface of the slide block.

[0006] Preferably, the support base has a lifting groove on its surface, and a lifting seat is slidably connected inside the lifting groove. The inner cavity of the lifting seat is fixed to another drive motor housing. Both ends of the lifting seat are threaded with lead screws, and both ends of the lead screws are connected to bearings on the inner wall of the lifting slide plate. The lead screws are driven by a drive assembly, which drives the lead screws to rotate, thereby driving the lifting seat to adjust its height and position, adjusting the drive wheel to the surface of the pipe, so that the device can be used for pipes with different diameters.

[0007] Preferably, the drive assembly includes a main gear, and a secondary gear is fixed to the top of each lead screw. The main gear and the secondary gear mesh with each other. The main gear is driven by a gear motor, which is fixed to the top of the support base. The gear motor drives the main gear to rotate, and the main gear drives the two secondary gears at both ends to rotate synchronously and in the same direction. The secondary gears drive the lead screw to rotate, thereby realizing synchronous adjustment of the lead screw and improving the stability of the lifting base.

[0008] Preferably, the fixed-length base has an array of adjustment holes on its surface, the slider is L-shaped, and the other end of the slider is bolted to the adjustment hole. The connecting rod has an array of fixing holes on its surface. According to the required length of the pipe, the position of the slider is adjusted, the slider and the corresponding adjustment hole are bolted, and then the fixing position of the rotating rod and the connecting rod is adjusted. The corresponding fixing hole is selected and bolted. The bolt hole position adjustment facilitates fixed length, and the operation is simple and the stability is high.

[0009] Preferably, the spacing between adjacent adjustment holes is equal, and the spacing between adjacent fixing holes is equal, which improves the length fixing accuracy.

[0010] Preferably, the diameter of the main gear is smaller than that of the secondary gear, which facilitates the adjustment of the transmission ratio.

[0011] Preferably, the lifting slide is a T-shaped groove, which improves the stability of the lifting seat.

[0012] Beneficial effects

[0013] In existing technologies, pipe cutting to a fixed length is frequently involved in machining. Currently, the main cutting methods are manual cutting and CNC cutting. Manual cutting requires manual measurement and marking before using a cutting machine. Because the cutting machine's speed and direction need to be manually controlled, it's difficult to ensure stability and consistency. This is not only inconvenient and inefficient, but also results in uneven cut surfaces, excessive burrs, and other quality problems, reducing product precision and quality stability. Furthermore, the high-temperature sparks, high-speed rotating blades, and sharp pipe edges generated by the cutting machine pose significant safety hazards to operators. CNC cutting is more precise, but inefficient and costly. To address these issues, this invention employs a simple automatic fixed-length device. The pipe is placed in the drive groove between the drive wheels, and the friction of the drive groove drives the pipe's movement. The gear motor then drives the main... The gears rotate, and the main gear drives the two auxiliary gears at both ends to rotate synchronously and in the same direction. The auxiliary gears drive the lead screw to rotate, thereby driving the lifting seat to adjust its height. The drive wheel is adjusted to the surface of the pipe. After adjustment, the position of the slider is adjusted according to the required length of the pipe. The slider and the corresponding adjustment hole bolts are fixed. Then the fixed positions of the rotating rod and the connecting rod are adjusted. The corresponding fixing holes are selected and the bolts are fixed. Finally, the drive motor is turned on, so that the drive wheels rotate in opposite directions, driving the pipe to move along the rotating rod until it contacts it. After contact, the rotating rod rotates, driving the connecting rod to push the sliding seat and the cutting box body to the inclined surface at the contact point, driving the cutting box body to move downward. At the same time, the external motor drives the cutting blade to rotate at high speed to complete the cutting. Under the action of the return spring, the cutting box body returns to its original position. Compared with manual cutting, the operation is simple, time-saving and labor-saving, and ensures the stability and consistency of the cutting. Compared with CNC cutting, this structure has a lower cost and higher efficiency. Attached Figure Description

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific implementation examples:

A sliding column is slidably connected to the top of the base 2. A cutting box 4 is fixed to the top of the sliding column. A cutting blade 5 is rotatably connected to the side of the cutting box 4 near the drive wheel 3. The cutting blade 5 is driven by an external motor. A return spring 8 is nested on the surface of the sliding column. A slide seat 6 is provided on the side of the cutting box 4 away from the cutting blade 5.

[0024] The support base 17 has a lifting groove on its surface, and a lifting seat 12 is slidably connected inside the lifting groove. The lifting groove is a T-shaped groove, which improves the stability of the lifting seat 12. The inner cavity of the lifting seat 12 is fixed to the housing of another drive motor 7. Both ends of the lifting seat 12 are threaded with lead screws 13, and both ends of the lead screws 13 are connected to bearings on the inner wall of the lifting slide plate. The lead screws 13 are driven by a drive assembly, which drives the lead screws 13 to rotate, thereby driving the lifting seat 12 to adjust its height and position, adjusting the drive wheel 3 to the surface of the pipe, so that this equipment can be used for pipes with different hole diameters. The drive assembly includes a main gear 15, and a secondary gear 14 is fixed to the top of the lead screws 13. The main gear 15 and the secondary gear 14 mesh with each other. The main gear 15 is driven by a gear motor 16, which is fixed to the top of the support base 17. The gear motor 16 drives the main gear 15 to rotate, and the main gear 15 drives the two secondary gears 14 to rotate synchronously and in the same direction. The secondary gears 14 drive the lead screw 13 to rotate, realizing the synchronous adjustment of the lead screw 13 and improving the stability of the lifting seat 12. The diameter of the main gear 15 is smaller than that of the secondary gear 14, which facilitates the adjustment of the transmission ratio.

[0025] The fixed-length base 18 has an array of adjustment holes 1801 on its surface. The slider 11 is L-shaped, and the other end of the slider 11 is bolted to the adjustment hole 1801. The connecting rod 10 has an array of fixing holes 1001 on its surface. According to the required length of the pipe, the position of the slider 11 is adjusted, and the slider is bolted to the corresponding adjustment hole 1801. Then, the fixing positions of the rotating rod 9 and the connecting rod 10 are adjusted, and the corresponding fixing hole 1001 is selected for bolt fixing. Adjusting the bolt hole position facilitates length setting, and the operation is simple and stable.

Then the fixed position of the rotating rod 9 and the connecting rod 10 is adjusted. The corresponding fixing hole 1001 is selected and bolted. Finally, the drive motor 7 is turned on to make the drive wheels 3 rotate in opposite directions, driving the pipe 1 to move along the rotating rod 9 until it contacts it. After contact, the rotating rod 9 rotates, driving the connecting rod 10 to push the slide 6. The sliding rod 6 and the cutting box 4 are both set as inclined surfaces, driving the cutting box 4 to move downward. At the same time, the external motor drives the cutting blade 5 to rotate at high speed to complete the cutting. Under the action of the return spring 8, the cutting box 4 returns to its original position.
