Description

Technical Field

[0001] This utility model relates to the technical field of thin-walled tube straightening equipment, and in particular to a thin-walled tube straightening and calendering machine. Background Technology

[0002] In the production and processing of thin-walled tubes, straightening is a crucial step in ensuring their subsequent performance. However, traditional thin-walled tube straightening and calendering machines suffer from numerous problems in practical applications, failing to meet the demands for high-quality and high-efficiency processing. Regarding the fixing of thin-walled tubes, the clamping structure design of traditional equipment is inadequate, often failing to accurately align the tubes and prone to misalignment during clamping. This causes the thin-walled tubes to easily loosen and shift during straightening due to the squeezing of the straightening rollers and their own rotation. Once the thin-walled tube shakes, it not only affects the stability of the straightening operation but also directly leads to a decrease in straightening accuracy, resulting in the tube's straightness failing to meet requirements and severely impacting product quality. Furthermore, the traditional clamping structure has poor adaptability; for thin-walled tubes of different diameters, corresponding clamping components usually need to be replaced to achieve effective fixing. This not only increases operational complexity but also prolongs production preparation time, reduces production efficiency, and limits the equipment's applicability. In terms of adjusting the straightening rollers, traditional equipment uses a cumbersome method for adjusting the roller spacing, resulting in low adjustment accuracy and slow speed. When processing thin-walled tubes of different diameters, it is often necessary to manually adjust multiple components to change the spacing of the straightening rollers. This is not only time-consuming and labor-intensive, but also difficult to precisely adjust the spacing to match the diameter of the thin-walled tube. This results in uneven stress on the thin-walled tube during the straightening process, with some areas being over-straightened and others under-straightened, affecting the straightening effect. Therefore, we propose a thin-walled tube straightening and calendering machine to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a thin-walled tube straightening and calendering machine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A thin-walled tube straightening and calendering machine includes: a base, inside which is a housing, and inside which is a fixing assembly, the fixing assembly including: a bidirectional lead screw, with two sets of threaded blocks threaded to the outer side of the bidirectional lead screw, a fixing block fixedly mounted on the top of each of the two sets of threaded blocks, a fixing rod fixedly mounted on the top of each of the two sets of fixing blocks, and an arc-shaped clamping plate fixedly mounted on the side of each of the two sets of fixing rods that are close to each other, with a thin-walled tube movably abutting between the two sets of arc-shaped clamping plates; a support base fixedly mounted on one side of the base, with a frame fixedly mounted on the top of the support base, and an adjusting assembly inside the frame, the adjusting assembly including: a rotating plate, with two sets of connecting rods hinged to the bottom of the rotating plate, a fixing frame hinged to the bottom of one end of each of the two sets of connecting rods, a slider fixedly mounted on the bottom of each of the two sets of fixing frames, and a straightening roller mounted on the bottom of each of the two sets of sliders; and an electric push rod II fixedly mounted on one side of the frame, the output end of which is fixedly connected to the slider located on the right side.

[0005] Preferably, a sliding groove is provided on the bottom inner wall of the base, a limiting block is fixedly installed at the bottom of the housing, the limiting block is slidably installed inside the sliding groove, and two sets of electric push rods are fixedly installed on the rear side of the base, the output ends of the two sets of electric push rods are fixedly connected to the housing.

[0006] Preferably, the bidirectional lead screw is rotatably mounted on the inner walls of both sides of the housing, a motor is fixedly mounted on one side of the housing, and a strip groove is formed on the inner wall of one side of the base, with the motor slidably mounted inside the strip groove.

[0007] Preferably, a motor body is fixedly installed on the top of each of the two sets of sliders, and the output shafts of the two sets of motor bodies are respectively fixedly connected to the corresponding straightening rollers.

[0008] Preferably, guide rods are slidably installed inside the two sets of fixing blocks, and the two ends of the guide rods are respectively fixedly connected to the inner walls of the two sides of the housing. A guide groove is opened on the top of the housing, and the two sets of fixing rods are slidably installed inside the corresponding guide grooves.

[0009] Preferably, a short plate is fixedly installed on the top of the frame, a rotating shaft is fixedly installed inside the rotating plate, the rotating shaft is rotatably installed on the top of the short plate, and two sets of limiting rods are slidably installed inside the two sets of sliders, with the two ends of the two sets of limiting rods respectively fixedly connected to the inner walls of the two sides of the frame.

[0010] In this utility model, a thin-walled tube straightening and calendering machine is provided with a fixing component, an electric push rod, and a limiting block. When the motor is started, it drives a bidirectional lead screw to rotate inside the housing. Since two sets of threaded blocks are threadedly connected to the bidirectional lead screw, the threaded blocks drive the fixing block and fixing rod to move synchronously. The fixing rod slides along the guide groove at the top of the housing, thereby driving two sets of arc-shaped clamps to approach each other until the arc-shaped clamps are tightly abutted against the thin-walled tube. Then, the two sets of electric push rods are started, pushing the housing to slide along the sliding groove at the bottom of the base. The housing drives the fixed thin-walled tube to move towards the straightening roller, accurately aligning and tightly abutting the thin-walled tube. This prevents the thin-walled tube from loosening or shifting due to force or rotation during the straightening process, providing a reliable guarantee for the stability of subsequent straightening operations. It effectively prevents the problem of decreased straightening accuracy caused by the swaying of the thin-walled tube, and can adapt to the fixing requirements of thin-walled tubes of different diameters without the need to replace clamping components, thus expanding the applicability of the equipment. In this invention, a thin-walled tube straightening and calendering machine is equipped with an adjustment component. When the electric push rod is activated, its output end pushes the right slider to slide along the limit rod. When the right slider moves, it drives the connecting rod that is hinged to it to move. The connecting rod pulls the rotating plate to rotate around the rotating shaft. The rotating plate drives the left slider to slide synchronously along the limit rod through another set of connecting rods. The two sets of sliders move in opposite directions, thereby adjusting the distance between the two sets of straightening rollers. This allows the distance between the straightening rollers to be quickly adjusted to a size that matches the diameter of the thin-walled tube, making it convenient to straighten thin-walled tubes of different specifications.

[0015] In this embodiment, a sliding groove is provided on the bottom inner wall of the base 2, and a limiting block 10 is fixedly installed on the bottom of the housing 4. The limiting block 10 is slidably installed inside the sliding groove. Two sets of electric push rods 3 are fixedly installed on the rear side of the base 2. The output ends of the two sets of electric push rods 3 are fixedly connected to the housing 4 to facilitate the movement of the fixing component 6 and the thin-walled tube 5. The bidirectional lead screw 601 is rotatably installed on the inner walls of both sides of the housing 4. A motor is fixedly installed on one side of the housing 4. A strip groove is provided on the inner wall of one side of the base 2. The motor is slidably installed inside the strip groove to facilitate the stable movement of the fixing component 6.

[0016] In this embodiment, motor bodies 9 are fixedly installed on the top of both sets of sliders 705. The output shafts of the two sets of motor bodies 9 are fixedly connected to the corresponding straightening rollers 8, which facilitates the rotation of the two sets of straightening rollers 8. Guide rods 606 are slidably installed inside the two sets of fixing blocks 603. The two ends of the guide rods 606 are fixedly connected to the inner walls of both sides of the housing 4. A guide groove is opened on the top of the housing 4.

The two sets of motor bodies 9 are started, and the motor bodies 9 drive the straightening rollers 8 to rotate. At the same time, the two sets of electric push rods 3 are started. The electric push rods 3 push the housing 4 to slide along the groove at the bottom of the base 2.
