Description

Technical Field

[0001] This invention relates to the field of cantilever straightening machine equipment technology, and more specifically, to a cantilever straightening machine straightening roller assembly disassembly device. Background Technology

[0002] Multi-roller cantilever straighteners are key equipment in small and medium-sized steel production lines, and their operating rate has a significant impact on the production line's capacity.

[0003] Currently, when replacing the straightening rollers of a multi-roll cantilever straightening machine for structural steel, the disassembly of the straightening rollers requires manual labor in conjunction with hydraulic jacks due to adhesion and other reasons. This results in high labor intensity for workers, long operation time, and low roller replacement efficiency, which in turn reduces the operating rate and production pace of the straightening machine. Summary of the Invention

[0004] The problem this invention addresses is how to improve roller changing efficiency.

[0005] To address the aforementioned problems, this invention provides a disassembly device for a cantilever straightener's straightening roller assembly, used for disassembling the straightening roller assembly. The disassembly device includes a bracket, a clamping and positioning assembly, and a top support assembly. The bracket is sleeved on the roller end of the straightening roller assembly. Both the clamping and positioning assembly and the top support assembly are connected to the bracket. The clamping and positioning assembly applies a radial force to the straightening roller assembly, and the top support assembly abuts against the straightener and applies an axial force to the straightening roller assembly, causing it to move away from the straightener.

[0006] Optionally, the clamping and positioning assembly includes a first hydraulic cylinder, a first pressure block, and a first base. The first base is connected to the bracket. The first hydraulic cylinder is arranged on the first base along the radial direction of the straightening roller group. The first hydraulic cylinder drives the first pressure block to move along the radial direction of the straightening roller group. The first pressure block is used to abut against the straightening roller group.

[0007] Optionally, a protrusion is provided on the end of the first pressure block opposite to the first hydraulic cylinder, and a groove is provided on the straightening roller group, wherein the protrusion is inserted into the groove.

[0008] Optionally, the first base is provided with a through hole, the length direction of the through hole is consistent with the moving direction of the first pressure block, at least a part of the first hydraulic cylinder and the first pressure block are located in the through hole, and a sliding plate is provided in the through hole, the first pressure block is slidably connected to the sliding plate.

[0009] Optionally, the cantilever straightener straightening roller assembly disassembly device further includes a pin, and the first pressure block is connected to the first hydraulic cylinder via the pin.

[0010] Optionally, a limit block is also provided on the first base, the limit block is connected to the first hydraulic cylinder, and the limit block is used to restrict the movement of the first hydraulic cylinder on the first base.

[0011] Optionally, two top support assemblies are provided, and the two top support assemblies are symmetrically arranged on the bracket with the axis of the straightening roller group as a reference.

[0012] Optionally, the top support assembly includes a second hydraulic cylinder, a second pressure block, and a guide member. The second hydraulic cylinder includes a piston rod and a cylinder body. The cylinder body is connected to the bracket, and the guide member is connected to the bracket. The guide member is sleeved on the piston rod and slidably connected to the piston rod. The sliding direction of the piston rod is consistent with the axial direction of the straightening roller group, and the piston rod extends from the guide member and is drivenly connected to the second pressure block. The second pressure block is used to abut against the straightening machine.

[0013] Optionally, the projection of the piston rod onto the second pressure block falls within the second pressure block.

[0014] Optionally, a support plate is provided on the bracket, the support plate is disposed opposite to the clamping and positioning assembly, and the support plate is engaged with the straightening roller group.

[0015] Compared with the prior art, the cantilever straightener straightening roller assembly disassembly device of the present invention connects both the clamping and positioning assembly and the top support assembly to the bracket. After the bracket is fitted onto the roller end of the straightening roller assembly, the clamping and positioning assembly and the top support assembly remain stable under the support of the straightening roller assembly. The clamping and positioning assembly applies radial force to the straightening roller assembly, while the top support assembly abuts against the straightener and applies axial force to the straightening roller assembly, moving it away from the straightener. While the connection between the straightening roller assembly and the bracket is stable under the action of the clamping and positioning assembly, the straightening roller assembly is disassembled under the action of the top support assembly. This reduces manual labor during straightening roller assembly disassembly and eliminates the need for hydraulic jacks, thereby improving roller changing efficiency. Attached Figure Description

[0026] Combination Figure 1 As shown, this embodiment of the invention provides a disassembly device for a straightening roller assembly of a cantilever straightener, used for disassembling the straightening roller assembly 10. It includes a bracket 1, a clamping and positioning component 2, and a top support component 3. The bracket 1 is sleeved on the roller end of the straightening roller assembly 10. The clamping and positioning component 2 and the top support component 3 are both connected to the bracket 1. The clamping and positioning component 2 is used to apply a radial force to the straightening roller assembly 10, and the top support component 3 is used to abut against the straightener and apply an axial force to the straightening roller assembly 10 to move away from the straightener.

[0027] Specifically, both the clamping and positioning assembly 2 and the top support assembly 3 are bolted to the bracket 1, and the clamping and positioning assembly 2 and the top support assembly 3 remain stable under the support of the bracket 1. In use, the bracket 1 is fitted onto the roller end of the straightening roller group 10, as shown below. Figure 1 As shown, taking the bracket 1 fitted onto the left end of the straightening roller assembly 10 as an example, after the bracket 1 is fitted onto the left end of the straightening roller assembly 10, the clamping and positioning assembly 2 applies a clamping force in the radial direction to the left end of the straightening roller assembly 10. Under the action of this clamping force, the clamping and positioning assembly 2 ensures a stable connection between the bracket 1 and the straightening roller assembly 10. Then, the top support assembly 3, supported by the bracket 1, applies a driving force in the axial direction to the straightening roller assembly 10. Under the action of this driving force, the straightening roller assembly 10 moves away from the straightener. Furthermore, the bracket 1 can also be connected to the front end of the telescopic arm of the quick roller change device. The telescopic arm can be raised and lowered, and the telescopic distance and lifting height are accurately detected by displacement sensors. Since the straightening roller assembly is installed on the straightening roller shaft and its position is relatively fixed, the disassembly device can be disassembled through position feedback from the displacement sensor and electrical control.

[0028] Therefore, in this embodiment, since both the clamping and positioning component 2 and the top support component 3 are connected to the bracket 1, after the bracket 1 is fitted onto the roller end of the straightening roller group 10, the clamping and positioning component 2 and the top support component 3 can remain stable under the support of the straightening roller group 10. The clamping and positioning component 2 is used to apply radial force to the straightening roller group 10, and the top support component 3 is used to abut against the straightener and apply axial force to the straightening roller group 10 to move away from the straightener. While the connection between the straightening roller group 10 and the bracket 1 is stable under the action of the clamping and positioning component 2, the straightening roller group 10 can be disassembled under the action of the top support component 3. In this way, the manual labor is reduced when the straightening roller group 10 is disassembled, and no hydraulic jack is required, thereby improving the roller changing efficiency.

[0029] Optionally, combined Figure 1 and Figure 2 As shown, the clamping and positioning assembly 2 includes a first hydraulic cylinder 21, a first pressure block 22 and a first base 23. The first base 23 is connected to the bracket 1. The first hydraulic cylinder 21 is arranged on the first base 23 along the radial direction of the straightening roller group 10. The first hydraulic cylinder 21 drives the first pressure block 22 to move along the radial direction of the straightening roller group 10. When the first pressure block 22 moves toward the straightening roller group 10, the first pressure block 22 abuts against the straightening roller group 10.

[0030] Specifically, the first base 23 is connected to the bracket 1 by bolts. The first hydraulic cylinder 21 is arranged radially on the first base 23 along the straightening roller group 10, that is, the first hydraulic cylinder 21 is arranged along the Z-axis direction. The first hydraulic cylinder 21 drives the first pressure block 22 to move radially along the straightening roller group 10. That is, the first hydraulic cylinder 21 realizes the reciprocating linear movement of the first pressure block 22 in the Z-axis direction. When the first pressure block 22 moves toward the straightening roller group 10, the first pressure block 22 presses against the straightening roller group 10, and the bracket 1 is sleeved on the straightening roller group 10. Thus, after the first pressure block 22 presses down on the straightening roller group 10, due to the interaction of forces, the first pressure block 22 can apply an upward force to the bracket 1. Thus, under the combined action of the first pressure block 22 and the bracket 1, the bracket 1 is stably connected to the straightening roller group 10.

[0031] Thus, by connecting the first base 23 to the bracket 1, the bracket 1 supports the first base 23. Then, by driving the first pressure block 22 to move radially along the straightening roller group 10 through the first hydraulic cylinder 21 set on the first base 23, and when the first pressure block 22 moves toward the straightening roller group 10, the first pressure block 22 abuts against the straightening roller group 10. In this way, not only is the structure of the clamping and positioning component 2 simplified, but also, since the first hydraulic cylinder 21 is used as the driving component, it is easy to realize the remote control of the first hydraulic cylinder 21 through the control system, so as to improve the degree of automation.

[0032] Optionally, combined Figure 1 and Figure 2As shown, a protrusion 221 is provided on the end of the first pressure block 22 that is away from the first hydraulic cylinder 21, and a groove is provided on the straightening roller group 10, with the protrusion 221 inserted into the groove.

[0033] Specifically, the straightening roller assembly 10 has a V-shaped groove, and the first pressure block 22 has a protrusion 221 on the end opposite to the first hydraulic cylinder 21, such as... Figure 1 As shown, the protrusion 221 is disposed at the lower end of the first pressure block 22. When the first pressure block 22 moves toward the straightening roller group 10, the protrusion 221 is inserted into the groove on the straightening roller group 10.

[0034] Thus, by providing a protrusion 221 on the end of the first pressure block 22 that is away from the first hydraulic cylinder 21, and by inserting the protrusion 221 into the groove on the straightening roller group 10, the connection stability between the first pressure block 22 and the straightening roller group 10 is improved.

[0035] Optionally, combined Figure 1 and Figure 2 As shown, a through hole is provided on the first base 23. The length direction of the through hole is consistent with the moving direction of the first pressure block 22. At least part of the first hydraulic cylinder 21 and the first pressure block 22 are located in the through hole, and a sliding plate 231 is provided in the through hole. The first pressure block 22 is slidably connected to the sliding plate 231.

[0036] Specifically, the first base 23 has a box-shaped structure with a through hole in the middle. The depth direction of the through hole is consistent with the moving direction of the first pressure block 22, i.e., the through hole is set along the Z-axis. The first hydraulic cylinder 21 and the first pressure block 22 are both located in the through hole, and the sliding plate 231 is bolted to the through hole. When the first pressure block 22 moves under the drive of the first hydraulic cylinder 21, the sliding plate 231 is slidably connected to the first pressure block 22. Furthermore, when the first hydraulic cylinder 21 is mounted in the form of a trunnion, the piston rod of the first hydraulic cylinder 21 is located in the through hole, and the cylinder body of the first hydraulic cylinder 21 can be located outside the through hole and connected to the first base 23.

[0037] Thus, by setting a sliding plate 231 in the through hole of the first base 23 and sliding the sliding plate 231 to the first pressure block 22, the sliding plate 231 guides the movement of the first pressure block 22. In this way, during the process of the first hydraulic cylinder driving the first pressure block 22 to move, the sliding plate 231 prevents the movement direction of the first pressure block 22 from deviating, thereby improving the movement stability of the first pressure block 22.

[0038] Optionally, combined Figure 1 and Figure 2 As shown, the disassembly device for the straightening roller assembly of the cantilever straightener also includes a pin 40, through which the first pressure block 22 is connected to the first hydraulic cylinder 21. This facilitates the assembly and disassembly of the first pressure block 22 and the first hydraulic cylinder 21.

[0039] Optionally, combined Figure 1 and Figure 2 As shown, a limit block 232 is also provided on the first base 23. The limit block 232 is connected to the first hydraulic cylinder 21, and the limit block 232 is used to restrict the movement of the first hydraulic cylinder 21 on the first base 23.

[0040] Specifically, the limiting block 231 is connected to the upper end of the first base 23 by bolts, and the limiting block 232 is connected to the cylinder body of the first hydraulic cylinder 21. When disassembling the straightening roller assembly 10, the limiting block 232 can restrict the movement of the first hydraulic cylinder 21 on the first base 23, that is, the limiting block 232 restricts the movement of the first hydraulic cylinder 21 in the Z-axis direction. In some embodiments, when the first hydraulic cylinder 21 is mounted in a trunnion manner, the limiting block 231 can also be connected to the trunnion on the first hydraulic cylinder 21.

[0041] Thus, the first hydraulic cylinder 21 is connected to the limiting block 232 on the first base 23, and the limiting block 232 is used to restrict the movement of the first hydraulic cylinder 21 on the first base 23. In this way, after the first pressure block 22 is engaged with the straightening roller group 10, the limiting block 232 can press against the first hydraulic cylinder 21 to prevent the first hydraulic cylinder 21 from moving upward, thereby improving the stability of the first hydraulic cylinder 21.

[0042] Optionally, combined Figure 3 As shown, there are two top support components 3, which are symmetrically arranged on the bracket 1 with the axis of the straightening roller group 10 as the reference.

[0043] Specifically, two top support components 3 are positioned at the left and right ends of the bracket 1, with the Y-axis as the center of symmetry. The number of top support components 3 can also be appropriately increased depending on the structure of the bracket 1.

[0044] Thus, by symmetrically arranging two top support components 3 on the bracket 1 with the axis of the straightening roller group 10 as the reference, the number of top support components 3 is increased. In this way, during disassembly, both top support components 3 can press against the straightening machine, thereby improving the disassembly efficiency of the straightening roller group 10.

[0045] Optionally, combined Figure 3 As shown, the top support assembly 3 includes a second hydraulic cylinder 31, a second pressure block 32, and a guide member 33. The second hydraulic cylinder 31 includes a piston rod and a cylinder body. The cylinder body is connected to the bracket 1. The guide member 33 is connected to the bracket 1. The guide member 33 is sleeved on the piston rod and slidably connected to the piston rod. The sliding direction of the piston rod is consistent with the axial direction of the straightening roller group 10. The piston rod extends out from the guide member 33 and is drivenly connected to the second pressure block 32. The second pressure block 32 is used to abut against the straightening machine.

[0046] Specifically, the second hydraulic cylinder 31 is arranged along the Y-axis. The cylinder body of the second hydraulic cylinder 31 is connected to the bracket 1 by bolts. The guide 33 is welded to the bracket 1 and is provided with a hole structure that matches the piston rod. The piston rod is slidably connected to the hole structure, that is, while the piston rod is extending and retracting, it also slides in the hole structure. The piston rod extends out from the guide 33 and can drive the second pressure block 32 to move in the Y-axis direction. When the piston rod drives the second pressure block 32 to move in the negative direction of the Y-axis, the second pressure block 32 abuts against the straightening machine.

[0047] Thus, by connecting both the cylinder and the guide 33 to the bracket 1, the guide 33 remains stable with the cylinder. Supported by the bracket 1, the guide 33 is fitted onto the piston rod and slidably connected to it. The sliding direction of the piston rod is consistent with the axial direction of the straightening roller group 10. The guide 33 guides the extension and retraction of the piston rod. When the piston rod extends from the guide 33 and drives the second pressure block 32 to abut against the straightener, the guide 33 can support the piston rod, thus preventing deformation of the piston rod due to the force generated after the second pressure block 32 abuts against the straightener. This improves the structural strength of the piston rod.

[0048] Optionally, combined Figure 3 As shown, the projections of the piston rods onto the second pressure block 32 all fall within the second pressure block 32.

[0049] Specifically, the piston rod is projected along the negative Y-axis toward the second pressure block 32 and falls entirely into the second pressure block 32.

[0050] In this way, the projection of the piston rod onto the second pressure block 32 falls into the second pressure block 32, making the size of the second pressure block 32 larger than the diameter of the piston rod. This not only increases the contact area between the second pressure block 32 and the straightening machine, but also improves the stability of the second pressure block 32 pressing against the straightening machine.

[0051] Optionally, combined Figure 1 As shown, a support plate 11 is provided on the bracket 1. The support plate 11 is arranged opposite to the clamping and positioning assembly 2, and the support plate 11 is engaged with the straightening roller group 10.

[0052] Specifically, the support plate 11 is located directly below the first pressure block 22, and the lower end of the support plate 11 is connected to the bracket 1. When the bracket 1 is fitted onto the straightening roller group 10, both the first pressure block 22 and the support plate 11 are engaged with the V-groove on the straightening roller group 10.

[0053] Thus, by setting a support plate 11 on the bracket 1 to engage with the straightening roller group 10, and the support plate 11 being positioned opposite to the clamping and positioning assembly 2, the straightening roller group 10 is positioned by both the support plate 11 and the clamping and positioning assembly 2. This further improves the stability of the bracket 1 on the straightening roller group 10 when disassembling the straightening roller group 10. Furthermore, when the first pressure block 22 is not engaged with the straightening roller group 10, the engagement between the support plate 11 and the straightening roller group 10 also serves as a preliminary installation and positioning function.

[0054] While the disclosure is as stated above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
