Description

Technical Field

[0001] This utility model relates to the field of steel structure processing technology, specifically a high-efficiency anti-jamming steel pipe length positioning and cutting structure. Background Technology

[0002] In modern industrial production, steel pipes are a commonly used building and manufacturing material, and the precision and efficiency of their cutting and processing have a significant impact on product quality and production efficiency. Traditional steel pipe cutting equipment typically employs relatively simple positioning methods for length positioning cuts. For example, some equipment relies solely on manual measurement of the steel pipe length and manual adjustment of the cutting position. This method is not only labor-intensive and time-consuming, but also highly susceptible to human error, resulting in significant deviations in the length of the cut steel pipes and failing to meet the production requirements of high-precision products. Even some more automated cutting equipment, while equipped with positioning devices, often lacks flexibility in its positioning structure. These devices are mostly limited to positioning cuts for steel pipes of specific specifications or ranges. When cutting steel pipes of different lengths and diameters, complex readjustments or even replacement of parts are required, leading to cumbersome and costly operations that severely impact production continuity and economic efficiency. Furthermore, some existing positioning cutting structures use clamps or similar methods to position the steel pipe length during cutting. After cutting, the bolts must be removed and the steel pipe taken off before the next cutting operation can begin. If the steel pipe is not removed in time, the cutting tool may jam, preventing subsequent cutting work from proceeding normally and greatly reducing work efficiency. Summary of the Invention

[0003] The main purpose of this utility model is to solve the above-mentioned existing technical problems and provide a high-efficiency anti-jamming steel pipe length positioning and cutting structure.

[0004] The specific solution of this utility model is: a high-efficiency anti-jamming steel pipe length positioning and cutting structure, including a cutting machine, a base, a cutter disc hinged to the top of the base, a pressure rod installed at one end of the cutter disc, the pressure rod being used to control the cutter disc to rotate around the hinge point towards the base, a fixed seat installed at the bottom of the base, a first guide rail provided at one end of the fixed seat, the surface of the first guide rail being provided with scale lines, a movable seat slidably installed on the first guide rail; a positioning structure is installed on the top of the movable seat, the positioning structure including a second guide rail installed on the top of the movable seat, a baffle slidably installed on the second guide rail. A pull rope is connected to the end of the baffle. The pull rope pulls the baffle to move horizontally along the width direction of the first guide rail. A fixed plate is installed on the top of the movable seat. A first guide rod is installed on one end of the fixed plate, and a second guide rod is installed on one end of the fixed seat. The other end of the pull rope passes through the first guide rod and the second guide rod in sequence and is fixedly connected to the pressure rod. When the pressure rod moves downward, it drives the baffle to move through the pull rope. A connecting plate is installed on the end of the baffle near the pull rope. A tension spring is connected to the surface of the connecting plate. The other end of the tension spring is connected to the fixed plate. A fixing structure is installed on the surface of the movable seat. This fixing structure is used to fix the movable seat.

[0005] According to the above technical solution, by adjusting the position of the moving seat so that its baffle is located on the corresponding scale line value, the length of the steel pipe is limited by the baffle when it is placed. When cutting, the baffle is moved by pulling the rope through the pressure rod, so that the steel pipe will fall off by itself after cutting and will not be clamped or blocked by the baffle, thus avoiding the situation of the blade jamming and allowing the next cutting work to be carried out quickly.

[0006] Furthermore, the movable seat has a rectangular structure with a hollow center, and the fixing structure includes two fastening bolts installed on the side wall of the movable seat. By tightening the fastening bolts, the movable seat can be fixed to the first guide rail.

[0007] According to the above technical solution, by fastening the bolts and threading them onto the surface of the movable seat, and by clamping the other end onto the surface of the first guide rail, a fastening effect can be quickly achieved.

[0008] Furthermore, the first guide rod has an L-shaped structure, and the side of the L-shaped structure that connects to the fixed plate is parallel to the baffle.

[0009] According to the above technical solution, the L-shaped first guide rod can keep the rope stable during movement, reducing deviation and jamming caused by improper guidance.

[0010] Furthermore, the fixing seat has a rectangular frame structure and covers the surface of the base.

[0011] According to the above technical solution, the rectangular frame structure has high structural strength and stability, and at the same time facilitates the installation of the first guide rail.

[0012] Furthermore, a rubber buffer pad is provided on the side of the baffle near the cutter head to prevent scratches on the surface of the steel pipe when positioning it.

[0013] According to the above technical solution, the friction between the steel pipe and the baffle can be effectively reduced by the rubber buffer pad, thus preventing surface scratches.

[0014] Furthermore, the second guide rod is in the shape of a rectangular square tube, and the height of the second guide rod is the same as the height of the pressure rod. The end of the pull rope away from the baffle passes through the top of the second guide rod and is connected to the pressure rod.

[0015] According to the above technical solution, the second guide rod is rectangular and at the same height as the pressure rod, so that the pull rope can pass smoothly through and connect to the pressure rod, accurately guiding the direction of the pull rope and ensuring that when the pressure rod is pressed down, the pull rope stably drives the baffle to move horizontally, thereby improving the accuracy and stability of the cutting positioning.

[0016] Furthermore, the straight-line distance from the incision to the outer wall of the fixing seat is 2~5cm, and the zero point of this scale line is determined by subtracting the distance between one end of the fixing seat and the incision.

[0017] According to the above technical solution, the zero position of the scale line is determined by deducting the distance from one end of the fixed seat to the cutting entrance, so that the scale value can directly correspond to the actual length of the steel pipe to be cut, without the need for manual calculation of this distance, which effectively improves the accuracy of the cutting length positioning and the convenience of operation.

[0018] Compared with the prior art, this utility model has the following advantages: The high-efficiency anti-jamming steel pipe length positioning and cutting structure is precisely positioned on the first guide rail according to the scale line by the movable seat, which can accurately determine the distance from the cutting entrance to the baffle, thereby accurately controlling the cutting length of the steel pipe. At the same time, the installation of the pull rope and the sliding baffle can move the baffle outside the steel pipe during the cutting process, so that it can fall naturally and will not be jammed by the baffle, thus effectively avoiding the occurrence of jamming, greatly improving production efficiency. Moreover, the baffle can be naturally returned to its original position by the tension spring, which can quickly start the next cutting operation. Attached Figure Description

[0024] See Figure 1-4 This embodiment is a high-efficiency anti-jamming steel pipe length positioning and cutting structure. The cutting machine is used to cut steel pipes. The cutting machine includes a base 1, with a cutter disc 2 hinged to the top of the base 1. A pressure rod 3 is installed at one end of the cutter disc 2. The pressure rod 3 is used to control the rotation of the cutter disc 2 around the intersection point toward the base 1 to cut the steel pipe. The top of the base 1 is provided with a cutting inlet 4, which is located directly below the cutter disc 2, so that the cutter disc 2 can cut into the cutting inlet 4 to complete the steel pipe cutting work. It should be noted that this cutting machine is existing technology and can be purchased and used directly. A fixed seat 5 is installed at the bottom of the base 1. A first guide rail 6 is welded to one end of the fixed seat 5. The top surface of the first guide rail 6 is provided with scale lines 7. A movable seat 8 is slidably installed on the first guide rail 6. A positioning structure is installed on the top of the movable seat 8. The positioning structure includes a second guide rail 9 welded to the top of the movable seat 8. A dovetail groove 10 is opened on one side of the second guide rail 9. A baffle 11 is slidably installed in the groove 10. A pull rope 12 is fixedly connected to the end of the baffle 11. The pull rope 12 pulls the baffle 11 to move horizontally along the width direction of the first guide rail 6. A fixed plate 13 is welded to the top of the movable seat 8. A first guide rod 14 is installed at one end of the fixed plate 13, and a second guide rod 15 is welded to one end of the fixed seat 5. The other end of the pull rope 12 passes through the first guide rod 14 and the second guide rod 15 in sequence and is fixedly connected to the pressure rod 3. When the pressure rod 3 moves downward, it drives the baffle 11 to move through the pull rope 12. A connecting plate 16 is installed at one end of the baffle 11 near the pull rope 12. The connecting plate 16 and the baffle 11 form an L-shaped structure. A tension spring 17 is fixedly connected to the surface of the connecting plate 16. The other end of the tension spring 17 is fixedly connected to the surface of the fixed plate 13, so that the baffle 11 can automatically return to its position for the next cutting operation. A fixing structure is installed on the surface of the movable seat 8. The fixing structure is used to fix the movable seat 8.

[0025] Furthermore, the movable seat 8 has a rectangular structure with a hollow center, and slides on the first guide rail 6. The fixing structure includes two fastening bolts 18 threaded to the side wall of the movable seat 8. The movable seat 8 can be fixed to the first guide rail 6 by tightening the fastening bolts 18.

[0026] Furthermore, the first guide rod 14 has an L-shaped structure, and one side of the L-shaped structure connected to the fixed plate 13 is parallel to the baffle 11, while the other side is parallel to the connecting plate 16. This allows the pull rope 12 to maintain the same direction of movement as the baffle 11 during operation, preventing the pull rope 12 from deviating and ensuring the accuracy of the pull rope 12 in pulling the baffle 11 to move.

[0027] Furthermore, the fixing seat 5 has a rectangular frame structure. The fixing seat 5 covers the surface of the base 1, which can effectively protect the surface of the base 1 and facilitate the welding of the first guide rail 6.

[0028] Furthermore, a rubber buffer pad 19 is provided on the side of the baffle 11 near the cutter head 2 to prevent scratches on the surface of the steel pipe when positioning the steel pipe.

[0029] Furthermore, the second guide rod 15 is in the shape of a rectangular square tube, and the height of the second guide rod 15 is the same as the height of the pressure rod 3. The end of the pull rope 12 away from the baffle 11 passes through the top of the second guide rod 15 and connects with the pressure rod 3, so that the connection point of the pull rope 12 and the pressure rod 3 and the through hole point of the second guide rod 15 are at the same height. This can accurately guide the direction of the pull rope 12, ensuring that when the pressure rod 3 is pressed down, the pull rope 12 stably drives the baffle 11 to move horizontally, improving the accuracy and stability of the cutting positioning.

[0030] Furthermore, the straight-line distance from the inlet 4 to the outer wall of the fixing seat 5 is 2~5cm. The zero position of the scale line 7 is determined by subtracting the distance between one end of the fixing seat 5 and the inlet 4, so that the scale value can directly correspond to the actual length of the steel pipe to be cut, without the need for manual calculation of this distance, effectively improving the accuracy of the cutting length positioning and the convenience of operation.

[0031] The working principle of this embodiment is as follows: In actual operation, the moving seat 8 is pushed to slide on the first guide rail 6 according to the target length of the steel pipe to be cut. With the help of the scale line 7 below the baffle 11, the distance from the cutting entrance 4 to the baffle 11 can be accurately determined, which corresponds to the length of the steel pipe to be cut.

[0032] After determining the position, fix the movable seat 8 by rotating the fastening bolt 18. When the cutting operation begins, first place the steel pipe on the base 1 so that one end of the steel pipe is in close contact with the baffle 11.

[0033] Then, press the pressure rod 3 to drive the cutter head 2 to perform the cutting action. When the pressure rod 3 moves downward, it will pull the baffle 11 to one side through the pull rope 12, causing the baffle 11 to slide on the second guide rail 9 and move away from the steel pipe. At the same time, the connecting plate 16 pulls the tension spring 17 to make elastic movement. After the steel pipe is cut, since the baffle 11 has moved to the outside of the steel pipe, the steel pipe can fall to the ground naturally without being blocked by the baffle 11, thus effectively avoiding the occurrence of cutter jamming.

[0034] This process greatly improves production efficiency. When the pressure bar 3 is lifted to prepare for the next cutting operation, the tension spring 17 makes an elastic movement again to pull the baffle 11 back to its original position to limit the steel pipe, which can quickly start the next cutting operation.
