Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of straightening inserts, specifically relating to an anti-detachment straightening insert mechanism for a large plate rolling machine. Background Technology
[0002] In the production of large cylindrical structures, there are generally two different production processes. One is to directly cast the cylinder using a large mold. This method can guarantee the shape, thickness, and curvature of the cylinder. However, due to its volume, the cylinder cannot undergo subsequent treatments such as quenching and normalizing after demolding. Therefore, the material strength of the cast cylinder may not meet the requirements of some equipment. The other method is to use pre-treated steel plates to roll them into the required size on a plate rolling machine and then weld the two ends together. This method allows for the selection of steel plates with the required strength according to the needs of the equipment to be produced through pre-treatment, without the need for subsequent overall strength reinforcement. However, the welded cylinder method also has a fatal drawback: the curvature of the cylinder formed by plate rolling cannot be completely consistent. The welded joint will also deform due to the principle of thermal expansion and contraction. In order to meet the requirements of both material strength and shape of the cylinder at the same time, a straightening operation is usually performed on the plate rolling machine after the plate rolling and welding.
[0003] However, during the process of straightening the cylinder, it is necessary to add shims between the outside of the cylinder and the plate rolling machine to adjust the cylinder's curvature. However, inserting shims directly into the outside of the cylinder will cause the plate rolling machine to squeeze out the shims during the complex cycle of straightening. Since large plate rolling machines use enormous force when straightening cylinders, the squeezed-out shims will also fly out with great force, which can cause injury to personnel. Summary of the Invention
[0004] This invention relates to an anti-detachment straightening block mechanism for a large plate rolling machine. A cylinder is positioned above the plate rolling machine, and a straightening block mechanism is located on the side of the cylinder. The straightening block mechanism includes a guide rod, a clamping and fixing mechanism, and a locking and positioning block mechanism. Clamping and fixing mechanisms are located on both sides of the guide rod. A locking and positioning block mechanism is located on the guide rod between the clamping and fixing mechanisms. One end of each clamping and fixing mechanism is connected to the cylinder, and the other end is connected to the guide rod. One end of the locking and positioning block mechanism is connected to the connection between the outer side of the cylinder and the plate rolling machine. The other end of the locking and positioning block mechanism... The end is connected to the guide rod. A straightening block mechanism is set on the side of the cylinder on the plate rolling machine to process the arc that needs to be straightened. The straightening block mechanism ensures that the block will not fly out due to the strong squeezing of the plate rolling machine during operation through multiple clamping and locking mechanisms. At the same time, it can accurately adjust and position the arc that needs to be straightened, eliminating the need for the operator to repeatedly bend over to adjust the position of the block. The block can be placed from a distance, while ensuring that the operator's hands are away from the connection between the plate rolling machine and the cylinder when placing the block, preventing accidents, reducing production risks, and improving production safety.
[0005] The guide rod is cylindrical and positioned parallel to the center of the cylinder on its outer side. From left to right, the outer side of the guide rod is equipped with a left clamping and fixing mechanism, a locking and positioning block mechanism, and a right clamping and fixing mechanism. The guide rod can align the clamping and fixing mechanism and the locking and positioning block mechanism on the same horizontal line, ensuring that the guide rod is parallel to the center of the cylinder. This ensures that the straightening block can be inserted parallel to the connection between the cylinder and the plate rolling machine, reducing the possibility of the block flying out while also ensuring the stability of the curvature during straightening.
[0006] The left clamping and fixing mechanism includes a left fixing plate, a connecting rod sleeve, and a clamping handle. The left fixing plate is rectangular in shape, with a clamping slot on its right side. A clamping handle is located on the upper right side of the left fixing plate. A fixing guide ring is horizontally arranged on the left surface of the clamping slot. A connecting rod sleeve is located inside the fixing guide ring. One end of the connecting rod sleeve is a screw, and the other end is a sleeve. The screw and the sleeve are perpendicularly connected. One end of the screw is connected to the outside of the sleeve, and the other end of the screw is located on the fixing guide ring. Inside the ring, the screw is connected to the fixed guide ring via a nut. The inner side of the sleeve is connected to the outer side of the guide rod. The clamping handle is threaded through and located inside the left fixed plate. One end of the clamping handle is located on the upper side of the left fixed plate, and the other end is located on the upper side of the clamping slot. The left clamping and fixing mechanism clamps the cylinder from the left side to ensure the stability of the left side of the straightening block mechanism. At the same time, the distance between the left fixed plate and the guide rod is adjusted according to the actual arc of the clamping, thereby ensuring that the guide rod and the center of the cylinder are horizontal.
[0007] The right clamping and fixing mechanism includes a right fixing plate, a connecting rod sleeve, and a clamping handle. The right fixing plate is rectangular in shape, with a clamping slot on its left side and a clamping handle on its upper left side. A fixing guide ring is horizontally arranged on the right surface of the clamping slot, and a connecting rod sleeve is located inside the fixing guide ring. One end of the connecting rod sleeve is a screw, and the other end is a sleeve. The screw and the sleeve are perpendicularly connected, with one end of the screw connected to the outside of the sleeve and the other end located on the fixing guide ring. Inside the ring, the screw is connected to the fixed guide ring via a nut. The inner side of the sleeve is connected to the outer side of the guide rod. The clamping handle is threaded through and located inside the right fixed plate. One end of the clamping handle is located on the upper side of the right fixed plate, and the other end is located on the upper side of the clamping slot. The right clamping and fixing mechanism clamps the cylinder from the right side to ensure the stability of the right side of the straightening block mechanism. At the same time, the distance between the right fixed plate and the guide rod is adjusted according to the actual arc of the clamping, thereby ensuring that the guide rod and the center of the cylinder are horizontal.
[0008] The locking and positioning block mechanism includes a positioning guide sleeve, a locking wheel, an auxiliary rod, and a straightening block. The positioning guide sleeve is composed of two intersecting cylindrical tubes connected in a cross shape. The inner side of the lower cylindrical tube of the positioning guide sleeve is connected to the outer side of the guide rod. An auxiliary rod is provided on the inner side of the upper cylindrical tube of the positioning guide sleeve, and a locking wheel is provided through the outer side of the upper cylindrical tube of the positioning guide sleeve. One end of the auxiliary rod is connected to the straightening block. The locking wheel is connected to the upper cylindrical tube of the positioning guide sleeve by a thread. The straightening block is triangular in shape, with one corner located at the connection between the outer side of the cylinder and the plate rolling machine. An auxiliary rod is provided symmetrically at the connection between the straightening block and the cylinder. The straightening block can be inserted from a distance using the auxiliary rod, ensuring personnel safety. At the same time, the locking wheel can lock the auxiliary rod to prevent the straightening block from flying out during operation and causing personnel injury. Furthermore, the positioning guide sleeve can be adjusted in vertical angle according to the actual position to be corrected, adapting to cylinders of various diameters.
[0009] The upper end of the clamping handle is equipped with a horizontal manual rotating rod, the lower end of the clamping handle is equipped with a clamping plate, and the middle part of the clamping handle is a threaded rod. The clamping and fixing mechanism is securely fixed to both sides of the cylinder through the threaded connection of the clamping handle. Beneficial effects
[0010] By installing a straightening insert mechanism on the side of the cylinder on the plate rolling machine, the arc to be straightened is processed by inserting the insert. This straightening insert mechanism uses multiple clamping and locking mechanisms to ensure that the insert will not fly out due to the strong pressure of the plate rolling machine during operation. It can also precisely adjust and position the arc to be straightened, eliminating the need for operators to repeatedly bend over to adjust the position of the insert. The insert can be placed from a distance, while ensuring that the operator's hands are kept away from the connection between the plate rolling machine and the cylinder when placing the insert, preventing accidents, reducing production risks, and improving production safety. The guide rod can set the clamping and fixing mechanism and the locking and positioning insert mechanism at the same level. Online, ensuring the guide rod is parallel to the center of the cylinder ensures the straightening block can be inserted parallel to the connection between the cylinder and the plate rolling machine, reducing the possibility of the block flying out and ensuring the stability of the arc during straightening. The straightening block can be inserted from a distance using the auxiliary rod, ensuring personnel safety. At the same time, the locking wheel can lock the auxiliary rod to prevent the straightening block from flying out during operation and causing personnel injury. Furthermore, the positioning guide sleeve can be adjusted according to the actual position to be straightened, adapting to cylinders of various diameters. The clamping and fixing mechanism is securely fixed to both sides of the cylinder through the threaded connection of the clamping handle. Attached Figure Description
