Description

Technical Field

[0001] This invention relates to the field of anvil replacement technology, and more particularly to a tooling for replacing anvil cylinders, and a method for replacing anvil cylinders using the tooling. Background Technology

[0002] During the forging process of the press, the replacement of production tools such as the flat anvil and the knife anvil is mainly achieved by the hydraulic cylinder device on the moving anvil platform. This hydraulic cylinder device is installed on the frame of the moving anvil platform, and there is an operating room above it. As a result, the hydraulic cylinder device is located in a narrow space at the bottom of the operating room. Therefore, not only is the surrounding space of the hydraulic cylinder device limited, but there are also no available lifting points above it. This makes the lifting of the hydraulic cylinder device quite inconvenient. When dismantling or installing the hydraulic cylinder device, it is difficult to lift it in and out, resulting in low work efficiency.

[0003] Currently, the construction process and specific methods used for disassembling and assembling hydraulic cylinder equipment are as follows: 1. Remove the dust cover and sliding plate of the hydraulic cylinder equipment; 2. Remove the oil pipes and anchor bolts of the hydraulic cylinder equipment; 3. Use a hydraulic jack to lift the hydraulic cylinder equipment; 4. Install sliding devices such as steel pipes at the bottom of the hydraulic cylinder equipment; 5. Use an external hand-operated hoist to horizontally move the hydraulic cylinder equipment. After moving the hydraulic cylinder equipment to the outside, use an indoor crane to hoist the hydraulic cylinder equipment. When reassembling, the disassembly process is repeated in reverse order.

[0004] Obviously, this method is used for hoisting hydraulic cylinder equipment. However, because personnel need to remove the anchor bolts of the hydraulic cylinder equipment in a confined space and move the hydraulic cylinder equipment horizontally, and because steel pipes and other devices are used as tools for horizontal sliding of the hydraulic cylinder equipment, it is easy to cause deflection, resulting in low work efficiency. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a tooling for changing the cylinder of an anvil transfer table, which can improve work efficiency and reduce labor load.

[0006] The present invention adopts the following technical solution:

[0007] This invention provides a tooling for changing the cylinder of a moving anvil, including an upper beam and two wheel seats. The upper beam is fitted with a cylinder fixing hoop that can slide along the axial direction of the upper beam. The bottom of the wheel seats has two or more rollers arranged in a straight line, and the rolling axes of each roller are parallel to each other. One end of the wheel seat in the direction of the roller extension is hinged to one end of the upper connecting rod, and the other end of the wheel seat in the direction of the roller extension is hinged to the cylinder body end of the lifting cylinder. One end of the upper beam is simultaneously hinged to the other end of the upper connecting rod on one wheel seat and the telescopic end of the lifting cylinder, and the other end of the upper beam is simultaneously hinged to the other end of the upper connecting rod on the other wheel seat and the telescopic end of the lifting cylinder.

[0008] Preferably, the upper beam includes a middle sleeve section and connecting sections at both ends. The connecting sections are threaded sections, and the radius of the connecting sections is smaller than that of the sleeve section. An installation sleeve is fitted on the connecting section. Nuts that can block the installation sleeve are screwed on both axial sides of the installation sleeve on the connecting section. The upper connecting rod and the telescopic ends of the lifting cylinder are both hinged to the installation sleeve.

[0009] Preferably, the wheel seat includes a lower connecting rod, a roller and one end of an upper connecting rod are simultaneously hinged to one end of the lower connecting rod, and a roller and the cylinder end of a lifting cylinder are simultaneously hinged to the other end of the lower connecting rod.

[0010] Preferably, the cylinder fixing hoop includes a connecting block, an upper half-ring hoop, and a lower half-ring hoop. The connecting block is sleeved on the upper beam and can slide along the axial direction of the upper beam. The upper half-ring hoop is detachably connected to the connecting block, and the lower half-ring hoop is detachably connected to the upper half-ring hoop to form a complete ring hoop structure. The hoop opening radius of the ring hoop structure is adapted to the radius of the cylinder equipment, and the hoop opening axis of the ring hoop structure is intersected with the axis of the upper beam.

[0011] The present invention also provides a method for replacing the hydraulic cylinder of an anvil, using the above-mentioned tooling for replacing the hydraulic cylinder of an anvil, and including the following steps:

[0012] S1: Remove the protective cover, slide plate, oil pipe and anchor bolts of the hydraulic cylinder equipment to be repaired on the anvil transfer table, place the hydraulic cylinder replacement tool on the anvil transfer table, and make the rollers on the two wheel seats of the hydraulic cylinder replacement tool on the anvil transfer table located in the slides on both sides of the anvil transfer table, and the hydraulic cylinder fixing hoop is set on the hydraulic cylinder equipment to be repaired.

[0013] S2: Start the lifting cylinder to lift the cylinder equipment to be repaired, and use the hand chain hoist located outside the operating room to move the cylinder equipment to be repaired together with the cylinder replacement tooling of the anvil table to the outside of the operating room. After controlling the lifting cylinder to fall back and disconnecting the cylinder fixing clamp from the cylinder equipment to be repaired, use the overhead crane in the plant to lift the cylinder equipment to be repaired away.

[0014] S3: The repaired hydraulic cylinder equipment is hoisted and transported by the overhead crane in the factory. The repaired hydraulic cylinder equipment is connected to the cylinder replacement fixture of the anvil table by the cylinder fixing clamp. After the lifting cylinder is started to lift the repaired hydraulic cylinder equipment, the repaired hydraulic cylinder equipment together with the cylinder replacement fixture of the anvil table is moved into the space below the operating room. The rollers on the two wheel seats of the cylinder replacement fixture of the anvil table are located in the slides on both sides of the anvil table. Then the lifting cylinder is started to lower the repaired hydraulic cylinder equipment into place.

[0015] S4: Disconnect the cylinder fixing clamp from the cylinder equipment that has been repaired, and use the hand-operated hoist located outside the operating room to move the cylinder replacement tool of the anvil transfer table outside the operating room, and reinstall the protective cover, slide plate, oil pipe and anchor bolts of the cylinder equipment that has been repaired on the anvil transfer table.

[0016] Preferably, the initial state of the anvil transfer cylinder replacement fixture is a split state. In step S1, the anvil transfer cylinder replacement fixture is first assembled outside the operating room, and then the assembled anvil transfer cylinder replacement fixture is placed on the anvil transfer table. In step S4, after reassembling the protective cover, slide plate, oil pipe and anchor bolts of the cylinder equipment that has been repaired on the anvil transfer table, the assembly state of the anvil transfer cylinder replacement fixture is released.

[0017] Preferably, two anvil transfer cylinder changing fixtures are used: one anvil transfer cylinder changing fixture is used to connect to the head side of the cylinder equipment, and the other anvil transfer cylinder changing fixture is used to connect to the tail side of the cylinder equipment.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] The present invention relates to a hydraulic cylinder replacement fixture for an anvil transfer table. The fixture is positioned within slideways on both sides of the anvil transfer table by two wheel seats, and is connected to the hydraulic cylinder equipment on the anvil transfer table by a cylinder fixing clamp. The hydraulic cylinder equipment is lifted using a lifting cylinder. Compared to conventional methods that use hydraulic jacks or sliding devices such as steel pipes to move the hydraulic cylinder equipment, the present invention integrates the functions of hydraulic jacks and sliding devices such as steel pipes, reducing labor load. Furthermore, due to the positioning between the fixture and the anvil transfer table, the disassembly and reassembly of the hydraulic cylinder equipment no longer requires additional positional correction, thereby improving work efficiency.

[0020] The method for replacing the anvil cylinder of the present invention naturally has the aforementioned beneficial effects because it adopts the above-mentioned tooling for replacing the anvil cylinder. Attached Figure Description

[0032] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0033] In the description of this invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0036] See Figure 1This embodiment provides a tooling for changing the cylinder of a moving anvil, including an upper beam 1 and two wheel seats 2. The upper beam 1 is fitted with a cylinder fixing hoop 3 that can slide along the axial direction of the upper beam 1. The bottom of the wheel seat 2 has two or more rollers 21 arranged in a straight line, and the rolling shafts of each roller 21 are parallel to each other. One end of the wheel seat 2 in the extension direction of the roller 21 is hinged to one end of the upper connecting rod 22, and the other end of the wheel seat 2 in the extension direction of the roller 21 is hinged to the cylinder end of the lifting cylinder 23. One end of the upper beam 1 is simultaneously hinged to the other end of the upper connecting rod 22 on one wheel seat 2 and the telescopic end of the lifting cylinder 23. The other end of the upper beam 1 is simultaneously hinged to the other end of the upper connecting rod 22 on the other wheel seat 2 and the telescopic end of the lifting cylinder 23.

[0037] In this embodiment, the anvil-shifting cylinder replacement fixture is limited within the slide rails 4 on both sides of the anvil-shifting table by two wheel seats 2, and is connected to the cylinder device 5 on the anvil-shifting table by a cylinder fixing clamp 3. The cylinder device 5 is lifted by the lifting cylinder 23. Compared with the conventional method of using hydraulic jacks and sliding devices such as steel pipes to move the cylinder device 5, the anvil-shifting cylinder replacement fixture in this embodiment not only integrates the functions of hydraulic jacks and sliding devices such as steel pipes, reducing the labor load, but also, due to the limitation between it and the anvil-shifting table, eliminates the need for additional position correction when disassembling and reassembling the cylinder device 5, thereby improving work efficiency.

[0038] Meanwhile, the cylinder fixing hoop 3 on the cylinder replacement fixture of the anvil shifting table in this embodiment can be slidably fitted onto the upper beam 1 along the axial direction of the upper beam 1, so that the setting position of the cylinder fixing hoop 3 can be flexibly adjusted.

[0039] Preferably, see Figure 2 The upper beam includes a middle sleeve section 11 and two end connecting sections 12. The connecting section 12 is a threaded section, and the radius of the connecting section 12 is smaller than the radius of the sleeve section 11. An installation sleeve is fitted on the connecting section 12. Nuts that can block the installation sleeve are screwed on both sides of the axial direction of the installation sleeve on the connecting section 12. The telescopic ends of the upper connecting rod 22 and the lifting cylinder 23 are both hinged to the installation sleeve.

[0040] The anvil transfer cylinder replacement fixture of this embodiment can flexibly adjust the maximum distance between the two wheel seats 2 by adjusting the screw position of the nut on the connecting section 12 according to the distance between the slide rails 4 on both sides of the anvil transfer table, so that the anvil transfer cylinder replacement fixture of this embodiment can be used on anvil transfer table equipment of different specifications.

[0041] Preferably, see Figure 1 The wheel seat 2 includes a lower connecting rod 24, a roller 21 and one end of an upper connecting rod 22 are simultaneously hinged to one end of the lower connecting rod 24, and a roller 21 and the cylinder end of a lifting cylinder 23 are simultaneously hinged to the other end of the lower connecting rod 24, thereby facilitating the disassembly of the roller 21, the upper connecting rod 22 and the lifting cylinder 23.

[0042] Preferably, see Figure 3 The cylinder fixing hoop 3 includes a connecting block 31, an upper half-ring hoop 32, and a lower half-ring hoop 33. The connecting block 31 is sleeved on the upper beam 1 and can slide along the axial direction of the upper beam 1. The upper half-ring hoop 32 is detachably connected to the connecting block 31, and the lower half-ring hoop 33 is detachably connected to the upper half-ring hoop 32 to form a complete ring hoop structure. The hoop opening radius of the ring hoop structure is adapted to the radius of the cylinder device 5, and the hoop opening axis of the ring hoop structure is intersected with the axis of the upper beam 1.

[0043] When it is necessary to attach the cylinder fixing hoop 3 to the cylinder device 5 of the anvil transfer table, the cylinder fixing hoop 3 can be successfully attached to the cylinder device 5 of the anvil transfer table by disengaging the detachable connection between the upper half hoop 32 and the lower half hoop 33, making the inner ring surface of the upper half hoop 32 fit with the upper part of the cylinder device 5 and the inner ring surface of the lower half hoop 33 fit with the lower part of the cylinder device 5, and then reconnecting the upper half hoop 32 and the lower half hoop 33.

[0044] It should be noted that when replacing the hydraulic cylinder device 5 with a diameter of 220mm, the load-bearing capacity of the anvil-moving hydraulic cylinder replacement tooling in this embodiment needs to reach 6t; the lifting stroke of the lifting cylinder 23 needs to reach 150mm.

[0045] Combination Figure 1 This embodiment also provides a method for replacing the anvil transfer cylinder, which uses the above-mentioned anvil transfer cylinder replacement fixture and includes the following steps:

[0046] S1: Remove the protective cover, slide plate, oil pipe and anchor bolts of the hydraulic cylinder equipment 5 to be repaired on the anvil transfer table, place the hydraulic cylinder replacement tool on the anvil transfer table, and make the rollers 21 on the two wheel seats 2 of the hydraulic cylinder replacement tool on the anvil transfer table located in the slides 4 on both sides of the anvil transfer table, and the hydraulic cylinder fixing clamp 3 is clamped on the hydraulic cylinder equipment 5 to be repaired.

[0047] S2: Start the lifting cylinder 23 to lift the cylinder equipment 5 to be repaired, and use the hand chain hoist located outside the operating room to move the cylinder equipment 5 to be repaired together with the cylinder replacement tooling of the anvil table to the outside of the operating room. After controlling the lifting cylinder 23 to fall back and releasing the connection between the cylinder fixing clamp 3 and the cylinder equipment 5 to be repaired, use the overhead crane in the factory to lift the cylinder equipment 5 to be repaired away.

[0048] S3: The repaired hydraulic cylinder equipment 5 is hoisted by the overhead crane in the factory and connected to the cylinder replacement fixture of the anvil table through the cylinder fixing clamp 3. After the lifting cylinder 23 is started to lift the repaired hydraulic cylinder equipment 5, the repaired hydraulic cylinder equipment 5 together with the cylinder replacement fixture of the anvil table is moved into the space below the operating room, so that the rollers 21 on the two wheel seats 2 of the cylinder replacement fixture of the anvil table are respectively located in the slide rails 4 on both sides of the anvil table. Then the lifting cylinder 23 is started to lower the repaired hydraulic cylinder equipment 5 into position.

[0049] S4: Disconnect the connection between the cylinder fixing clamp 3 and the repaired cylinder equipment 5. Use the hand chain hoist located outside the operating room to move the cylinder replacement tool of the anvil transfer table outside the operating room, and reinstall the protective cover, slide plate, oil pipe and anchor bolts of the repaired cylinder equipment 5 on the anvil transfer table.

[0050] The method for replacing the anvil cylinder in this embodiment, by employing the aforementioned anvil cylinder replacement fixture, can greatly improve the construction efficiency of the anvil cylinder replacement operation.

[0051] Preferably, the initial state of the anvil transfer cylinder replacement fixture is a split state. In step S1, the anvil transfer cylinder replacement fixture is first assembled outside the operating room, and then the assembled anvil transfer cylinder replacement fixture is placed on the anvil transfer table. In step S4, after reassembling the protective cover, slide plate, oil pipe and anchor bolts of the cylinder equipment 5 that has been repaired on the anvil transfer table, the assembly state of the anvil transfer cylinder replacement fixture is released.

[0052] Preferably, two anvil transfer cylinder changing fixtures are used: one anvil transfer cylinder changing fixture is used to connect to the head side of the cylinder device 5, and the other anvil transfer cylinder changing fixture is used to connect to the tail side of the cylinder device 5.

[0053] Since the hydraulic cylinder equipment of the anvil transfer table is relatively heavy, two anvil transfer table hydraulic cylinder replacement fixtures are used to support the head and tail sides of the hydraulic cylinder equipment 5. This can reduce the load on a single anvil transfer table hydraulic cylinder replacement fixture and extend its service life. It also facilitates the safe implementation of the anvil transfer table hydraulic cylinder replacement method in this embodiment.

[0054] The aforementioned tooling and method for replacing the anvil cylinder can solve the problem of improving the efficiency of disassembly and assembly of the anvil cylinder equipment and reducing the labor load in confined spaces. It has been practically applied in the replacement project of the anvil cylinder of the 45MN fast forging machine at Daye Special Steel Forging Plant. The tooling and method have greatly improved construction efficiency and created considerable economic benefits.

[0055] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
