A straightening mechanism for seamless steel pipes

Abstract

This utility model relates to the field of steel pipe straightening and discloses a straightening mechanism for seamless steel pipes, including a base. The top of the base has symmetrically arranged moving grooves. Moving seats are symmetrically arranged within the inner cavities of the two moving grooves and are slidably mounted thereon. The top of the moving seats has an arc groove. An adjusting seat is located at the center of the top of the base. Straightening rods are rotatably connected to both sides of the adjusting seat. This seamless steel pipe straightening mechanism, through a second dual-axis motor and a stud, moves the moving seat containing the steel pipe into the moving groove, while the other moving seat moves out. During this process, in conjunction with a first dual-axis motor, the straightening rod drives the straightening block to rotate and enter the steel pipe. After straightening is completed, a new steel pipe to be straightened is placed into the right moving seat and limited, and the above process is repeated in reverse. Simultaneously, the straightened steel pipe separates from the straightening block, and the other straightening block enters the new steel pipe to be straightened for straightening. This solves the problem that existing straightening mechanisms are unable to stably and quickly straighten steel pipes continuously.

Description

Technical Field

[0001] This utility model relates to the field of steel pipe straightening technology, specifically a straightening mechanism for seamless steel pipes. Background Technology

[0002] Steel pipe straightening is a process that uses external force to cause elastic or plastic deformation in the steel pipe, thereby correcting bends and restoring straightness. During the production process, steel pipes may bend or twist due to various reasons (such as uneven rolling, transportation collisions, etc.). This not only affects the appearance but may also reduce the performance and even pose safety hazards.

[0003] Patent CN217831336U discloses a straightening mechanism for seamless steel pipes. It includes a base with a long groove on its surface. A long plate is slidably connected inside the long groove. A fixing block is fixedly installed at the end of the long plate. A first motor is fixedly installed on the surface of the fixing block. This device simplifies the operation of the steel pipe during straightening by setting up a long rod, a straightening block, a cylinder, a rubber block, and a driving device. It also simplifies the equipment and achieves the purpose of being easy to operate and carry.

[0004] However, this device only has one straightening block inside. This means that after the straightening block is introduced into the steel pipe for straightening, the long plate must be moved to completely remove the straightening block, and the steel pipe must be disassembled and reinstalled with a new steel pipe to be straightened before operation can continue. The straightening operation cannot continue during the process of removing the straightening block, thus affecting the straightening efficiency of the steel pipe. To address this, a straightening mechanism for seamless steel pipes is proposed to solve the problem that existing straightening mechanisms cannot stably and quickly straighten steel pipes continuously.

[0011] Preferably, one end of the movable seat is provided with a stabilizing groove, the inner cavity of the stabilizing groove is symmetrical and fixedly connected with a stabilizing rod, the adjusting arm is located in the stabilizing groove and is penetrated by the stabilizing rod, and the adjusting arm and the stabilizing rod are slidably connected.

[0012] Preferably, the adjustment mechanism includes a fixed frame fixedly connected to the top of the base, with symmetrically formed sliding grooves on the cavity walls at both ends of the fixed frame, and a limit rod and a hydraulic telescopic column fixedly connected to the symmetrical inner cavity of the fixed frame.

[0015] (III) Beneficial Effects

[0016] 1. The seamless steel pipe straightening mechanism uses a second dual-axis motor in conjunction with a stud to move a moving seat containing the steel pipe into a moving slot, while the other moving seat moves out. During this process, in conjunction with the first dual-axis motor, the straightening rod drives the straightening block to rotate and enter the steel pipe. After straightening is completed, a new steel pipe to be straightened is placed into the right moving seat for limiting, and the above process is repeated in reverse. As the straightened steel pipe separates from the straightening block, the other straightening block enters the new steel pipe to be straightened for straightening, thus solving the problem that existing straightening mechanisms are unable to stably and quickly straighten steel pipes continuously.

[0017] 2. In this seamless steel pipe straightening mechanism, after the steel pipe is placed in the arc groove of the moving seat, the position of the limiting frame is adjusted according to the length of the steel pipe by the L-shaped slider in the L-shaped slide groove. After the limiting plate is adjusted to the appropriate limiting position of the steel pipe, the electric push rod is activated to drive the limiting plate to move down and the steel pipe to make contact. While limiting the steel pipe, the limiting frame and the L-shaped slider will have an upward force, which will cause the L-shaped slider and the L-shaped slide groove to form a compressive force, thereby limiting the limiting frame and improving the stability of the steel pipe straightening process of this seamless steel pipe straightening mechanism.

[0025] Furthermore, the output shaft of the first dual-axis motor 8 is fixedly connected to the straightening rod 6, the output shaft of the second dual-axis motor 13 is fixedly connected to the stud 14, the stud 14 passes through the movable seat 3 and the two are threadedly connected, and the limit block 18 is fixedly connected to the movable seat 3.

[0026] Furthermore, the stabilizing mechanism 9 includes an adjusting arm 901 slidably disposed on one side of the movable seat 3, and a bearing 902 is disposed on the top of the adjusting arm 901. The bearing 902 is located on the outer ring of the straightening rod 6 and the two are in contact.

[0027] Furthermore, a stabilizing groove 903 is provided at one end of the movable seat 3. The inner cavity of the stabilizing groove 903 is symmetrical and fixedly connected to a stabilizing rod 904. The adjusting arm 901 is located in the stabilizing groove 903 and is penetrated by the stabilizing rod 904. The adjusting arm 901 and the stabilizing rod 904 are slidably connected. When the adjusting seat 5 is adjusted by the adjusting mechanism 10, the adjusting arm 901, together with the bearing 902, moves with the straightening rod 6 in coordination with the stabilizing rod 904 in the stabilizing groove 903, ensuring that the bearing 902 moves with the movable seat 3, thereby improving the stability of the straightening rod 6, that is, ensuring the stability of the steel pipe straightening process.

[0028] Furthermore, the adjustment mechanism 10 includes a fixed frame 101 fixedly connected to the top of the base 1. The fixed frame 101 has symmetrically opened sliding grooves 102 on both ends of its cavity wall.

The L-shaped slider 115 is fixedly connected to the limiting frame 111. After the steel pipe is placed in the arc groove 4 in the movable seat 3, the position of the limiting frame 111 is adjusted according to the length of the steel pipe by the L-shaped slider 115 in the L-shaped groove 114. Then, the limiting plate 112 is adjusted to the appropriate limiting position of the steel pipe. The electric push rod 113 is then activated to drive the limiting plate 112 to move down and the steel pipe is pressed into contact. While limiting the steel pipe, the limiting frame 111 and the L-shaped slider 115 will both have an upward force, which will cause the L-shaped slider 115 to form a pressing force with the L-shaped groove, thereby limiting the limiting frame 111 and improving the stability of the steel pipe straightening process of this seamless steel pipe straightening mechanism.

[0031] Working principle: When using this seamless steel pipe straightening mechanism, the steel pipe to be straightened is placed into the arc groove 4 within the moving seat 3 of the moving groove 2, ensuring that one end of the steel pipe is in contact with the baffle 12. The limiting mechanism 11 then limits the steel pipe's position. The first dual-axis motor 8 and the second dual-axis motor 13, along with the stud 14, are activated, moving the moving seat 3 containing the steel pipe into the moving groove 2, while the other side of the moving seat 3 moves out. During this process, the straightening rod 6 drives the straightening block 7 to rotate and enter the steel pipe. After straightening is completed, the new pipe to be straightened is placed... The straight steel pipe is placed into the right movable seat 3 and limited, and the above process is repeated in reverse. While the straightened steel pipe separates from the straightening block 7, the other side of the straightening block 7 enters the new steel pipe to be straightened for straightening. This solves the problem that the existing straightening mechanism is difficult to straighten the steel pipe continuously and stably and quickly. When the straightened steel pipe moves to the point of separation from the straightening block 7, the limitation mechanism 11 on the steel pipe is released, the steel pipe is taken out and replaced with a new steel pipe to be straightened. This process is repeated to continuously straighten the steel pipe.
