Description
Technical Field
[0001] This utility model relates to the field of high-frequency straight seam welded pipe processing technology, specifically a high-frequency straight seam welded pipe cutting saw with height adjustment function. Background Technology
[0002] High-frequency straight seam welded pipe is a welded steel pipe made by rolling steel plates or strips into circular or irregular cross-sections using high-frequency induction welding technology. It features high production efficiency, low cost, high precision, and stable mechanical properties. It is mainly used for conveying low-pressure fluids such as water, coal and gas, fire fighting, air, oil, and heating steam, as well as for mechanical structures such as agricultural greenhouses, furniture, and scaffolding.
[0003] A high-frequency straight seam welded pipe cutting and sawing machine with height adjustment function, disclosed in CN216966469U, adopts a worm gear and worm wheel, as well as a guide plate and scale ring, so that the cutting and sawing machine has a precise rotation adjustment structure. With the threaded connection of the rotating rod and the mating sleeve, and the sliding connection of the guide groove and the guide frame, the cutting and sawing machine has a stable height adjustment function. By setting up a baffle plate, the cutting and sawing machine has a safety protection structure.
[0004] This high-frequency straight seam welded pipe cutting saw has a height adjustment function. It works in conjunction with a second motor, a rotating rod and a connecting sleeve, so that the connecting sleeve can drive the cutting saw seat downward through the connecting seat, so that the cutting saw seat can cut the high-frequency straight seam welded pipe. However, the device does not have a mechanism to adjust the cutting saw seat left and right. When the cutting saw seat is not in the correct position for cutting the high-frequency straight seam welded pipe, the position of the high-frequency straight seam welded pipe needs to be adjusted frequently, which affects the work efficiency. Therefore, it needs to be improved. Utility Model Content
[0005] The purpose of this invention is to provide a high-frequency straight seam welded pipe cutting and sawing machine with height adjustment function to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-frequency straight seam welded pipe cutting and sawing machine with height adjustment function, including a support column, a processing table fixedly connected to the top of the support column, a clamping mechanism provided on the top of the processing table, an adjustment mechanism provided at the bottom of the processing table, a PLC controller fixedly connected to the right side of the bottom of the processing table, and a high-frequency straight seam welded pipe body provided inside the clamping mechanism;
[0007] The adjustment mechanism includes a fixed plate, which is fixedly connected to the bottom back of the processing table. A drive motor is fixedly connected to the left side of the fixed plate, and a threaded rod is fixedly connected to the right side of the drive motor. The threaded rod is rotatably connected to the inner side of the fixed plate. A threaded plate is threadedly connected to the outer side of the threaded rod, and a slider is fixedly connected to the inner side of the threaded plate. A support frame is fixedly connected to the top of the threaded plate, and a first hydraulic cylinder is fixedly connected to the top of the support frame. A lifting plate is fixedly connected to the bottom of the first hydraulic cylinder, and an arc-shaped plate is fixedly connected to the bottom of the lifting plate. A rotating motor is fixedly connected to the left side of the arc-shaped plate, and a rotating shaft is fixedly connected to the right side of the rotating motor. The rotating shaft is rotatably connected to the inner side of the arc-shaped plate, and a saw blade is fixedly connected to the outer side of the rotating shaft.
[0008] Preferably, the inner side of the processing table is provided with a limiting groove corresponding to the movement trajectory of the slider, and the slider is slidably connected inside the limiting groove. The limiting groove can limit the slider, so that the slider can limit the threaded plate during the movement, making the threaded plate more stable during the movement.
[0009] Preferably, the inner side of the support frame is provided with a sliding groove corresponding to the movement trajectory of the lifting plate, and the lifting plate is slidably connected inside the sliding groove. Through the sliding groove, the lifting plate can slide inside the support frame, making the lifting plate more stable during the lifting process.
[0010] Preferably, the inner side of the lifting plate is provided with a fixing groove, and the saw blade is rotatably connected to the inside of the fixing groove. The fixing groove allows the saw blade to rotate inside the lifting plate, making it less likely for the lifting plate to obstruct the rotation of the saw blade.
[0011] Preferably, the clamping mechanism includes a support plate, which is fixedly connected to the top of the processing table. A second hydraulic cylinder is fixedly connected to the outer side of the support plate. A linkage plate is fixedly connected to the inner side of the second hydraulic cylinder. A limit rod is fixedly connected to the outer side of the linkage plate, and a V-shaped clamping plate is fixedly connected to the inner side of the linkage plate.
[0012] Preferably, there are two limiting rods, which are fixedly connected to the left and right sides of the outer side of the linkage plate, and the limiting rods are slidably connected to the inner side of the support plate. The limiting rods can limit the linkage plate, making the linkage plate more stable when it drives the V-shaped clamp to move.
[0013] Preferably, the V-shaped clamp is disposed on the outside of the high-frequency straight seam welded pipe body, and the inner side of the V-shaped clamp is in close contact with the outer wall of the high-frequency straight seam welded pipe body. The V-shaped clamp can clamp and fix high-frequency straight seam welded pipe bodies of different diameters, making the high-frequency straight seam welded pipe body more stable during the cutting process.
[0014] Compared with the prior art, this utility model provides a high-frequency straight seam welded pipe cutting and sawing machine with height adjustment function, which has the following beneficial effects:
[0015] This high-frequency straight seam welded pipe cutting saw has a height adjustment function. In the adjustment mechanism, the drive motor drives the threaded rod to rotate, so that the threaded plate slides smoothly in the limiting groove of the processing table through the slider. In conjunction with the first hydraulic cylinder, the lifting plate moves up and down along the slide groove of the support frame, which can realize the precise positioning of the saw blade in the horizontal and vertical directions. It can quickly adapt to the high-frequency straight seam welded pipe sawing needs of different heights and positions.
[0016] This high-frequency straight seam welded pipe cutting saw features height adjustment. The second hydraulic cylinder of the clamping mechanism pushes the linkage plate, causing the V-shaped clamping plate to move closer to the high-frequency straight seam welded pipe body. Utilizing the fit design between the V-shaped clamping plate and the outer wall of the welded pipe, it can stably clamp welded pipes of different diameters, ensuring that the welded pipe remains fixed during the sawing process. This avoids sawing deviations caused by the shaking of the welded pipe, thereby improving sawing quality and safety. Attached Figure Description

[0031] Furthermore, a fixing groove is provided on the inner side of the lifting plate 59, and the saw blade 501 is rotatably connected to the inside of the fixing groove.
