Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools for forging hammers, and particularly relates to an auxiliary tool for disassembling and assembling a hammer rod of a forging hammer. Background Art

[0002] A forging hammer is a forging machine that uses a pneumatic or hydraulic transmission mechanism to make the falling part, generally structures such as a piston, a hammer rod, a hammer head, an upper anvil or an upper die, etc., generate motion and accumulate kinetic energy, and apply it to a forging in a very short time, so that the forging obtains plastic deformation energy and completes various forging processes. As shown Figure 1 in the figure, a general forging hammer is composed of a machine body (1), a working part (2), a power transmission part (3), a power distribution and control part (4), etc., and the hammer rod (5) is an important part that connects the working part (2) and the power transmission part (3) and can bear elastic bending deformation.

[0003] Due to the special use conditions of the forging hammer, the working part (2) and the power transmission part (3) are frequently worn, resulting in the need for frequent maintenance of the forging hammer. During the maintenance process, it is necessary to disassemble and assemble the connected hammer rod. Due to the installation position limitation of the hammer rod, generally, the hammer rod is hoisted in and out from the main cylinder end (6) of the power head. The main cylinder is connected to the hammer body, and it is huge in volume and high from the ground. At the same time, considering the existing length of the hammer rod, a large workshop space and hoisting equipment space are required to complete the hoisting with the lifting ring bolt at the top of the hammer rod.

[0004] However, in most cases, the workshop space and the hoisting equipment travel cannot meet the requirement of hoisting the hammer rod in or out at one time. Instead, it is necessary to use the method shown Figure 2 in the figure. First, the hammer rod is hoisted out a part through the lifting ring bolt at the top of the hammer rod, and then a sling (or steel wire rope) (8) is tied to the rod body of the hammer rod and the hammer rod is slowly hoisted out with a hoist (7). This method first requires secondary hoisting, and the hoisting process is slow and cumbersome. Secondly, due to the smooth rod body, the binding with the sling is extremely likely to cause safety or quality accidents, resulting in a long binding process time for the sling and a low success rate, leading to extremely low assembly efficiency. And during the hoisting of the sling (or steel wire rope), due to unbalanced hoisting, it is also easy to damage the hammer rod and the forging hammer cylinder liner. If the operation is improper, it is easy to make the sling (or steel wire rope) scratch the control mechanism above the hammer rod, causing the overall equipment to malfunction or the service life to be shortened.

[0005] Therefore, to solve the problems of the cumbersome hoisting process of the existing hammer rod and the easy occurrence of safety accidents, etc., an auxiliary tool for disassembling and assembling a hammer rod of a forging hammer is now needed. Content of the Utility Model

[0006] The utility model aims to provide an auxiliary tooling for disassembling and assembling the hammer rod of a forging hammer, which can complete the disassembly and assembly process of the hammer rod at one time, can quickly complete the installation operation, improve the operation safety, and enhance the convenience and reuse rate of the tooling.

[0007] To achieve the above object, the utility model adopts the following technical scheme:

[0008] The utility model has a simple structure, high safety, can be reused, and has a high hanging efficiency of the hammer rod. Specifically, an auxiliary tooling for disassembling and assembling the hammer rod of a forging hammer is provided, which includes a first clamping member and a second clamping member arranged at the hoisting part of the hammer rod; the first clamping member and the second clamping member are oppositely arranged around the hammer rod to clamp and fix the hammer rod from the outside; a first lifting lug is arranged in the middle of the first clamping member, and a second lifting lug is arranged in the middle of the second clamping member, and the first lifting lug and the second lifting lug are oppositely arranged.

[0009] The principle and advantages of this scheme are:

[0010] Due to the special use conditions of the forging hammer, the working part and the power transmission part are frequently worn, resulting in the need for frequent maintenance of the forging hammer. During the maintenance process, it is necessary to disassemble and assemble the hammer rod. At present, for the hoisting of the hammer rod, generally, the hammer rod is hoisted in and out from the main cylinder end of the power head. The main cylinder is connected to the hammer body, which is huge in volume and relatively high from the ground. Coupled with the length of the hammer rod itself, a large workshop space and hoisting equipment space are required to complete it with the lifting ring bolt at the top of the hammer rod. However, in many cases, the workshop space and the hoisting equipment travel cannot meet the requirement of hoisting the hammer rod in or out at one time. Usually, after the hammer rod is hoisted out a certain distance, due to the upper space reaching the limit and unable to move further, it is necessary to tie a sling to the rod body of the hammer rod and then slowly hoist it out with a hoist, resulting in secondary hoisting. Moreover, the rod body of the hammer rod is relatively smooth, and tying the sling is extremely likely to cause safety or quality accidents, and the tying time is long and the success rate is low, resulting in extremely low assembly efficiency.

[0011] This scheme adopts two symmetrical clamping members and is fixedly connected through the connecting end, so that it can clamp the hammer rod. At the same time, an anti-slip layer is arranged inside the clamping member to further ensure the stability of the clamping member installation and avoid displacement and safety accidents. Lifting lugs for binding slings or chains are respectively arranged at the middle positions of the clamping members, making the sling binding more convenient and safe, reducing the tying time, increasing the success rate, and improving the hoisting efficiency. The symmetrically arranged lifting lugs can also ensure the balance and stability of the hoisting and reduce the occurrence of safety accidents. Using this scheme has the following advantages:

[0012] 1. The tooling directly clamps the hammer rod with a semi-circular structure and will not damage the surface of the hammer rod.

[0013] 2. This tooling is clamped by bolts and can be adjusted to any part between the clamps at a position 1 / 8 - 2 / 5 of the length of the hammer rod from the top of the hammer rod according to the actual situation, so as to adapt to the environment with a small space and insufficient lifting stroke, and is more flexible and convenient to use.

[0014] 3. This tooling has two symmetrical lifting rings, which can ensure the lifting center and protect the mechanism above the equipment and the assembly quality of the hammer rod.

[0015] 4. This sling has a simple structure, strong manufacturability, wide applicability, can be reused, has a low manufacturing cost, is convenient for installation and disassembly, and has a higher lifting efficiency.

[0016] Further, the first clamping member and the second clamping member are of an arc-shaped structure, and the arc radius is the same as the radius of the hammer rod. This ensures the stability and operability of the clamping.

[0017] Further, an anti-slip layer is provided on the inner side walls of the first clamping member and the second clamping member, and the anti-slip layer contacts the surface of the hammer rod. This avoids the offset or slipping caused by the smooth surface of the hammer rod and ensures the stability of the clamping.

[0018] Further, connection holes are respectively provided at the connection parts of the first clamping member and the second clamping member. This is convenient for installation and connection.

[0019] Further, the hammer rod lifting part is located at a position 500 - 600 mm from the top of the hammer rod. This ensures that the one-time lifting can be completed in a small space.

[0020] Further, the first lifting lug includes a first connecting rod, the first connecting rod is vertically arranged in the middle of the first clamping member, and a first mounting ring is provided at the end of the first connecting rod.

[0021] Further, the second lifting lug includes a second connecting rod, the second connecting rod is vertically arranged in the middle of the second clamping member, and a second mounting ring is provided at the end of the second connecting rod.

[0022] Further, compression bolts for connection and fixation are respectively provided on the connection holes.

[0023] Further, the widths of the first clamping member and the second clamping member are 40 - 70 mm. This is to ensure that they can bear the gravity of the hammer rod and the lifting, and guarantee the stability of the lifting process.

[0024] Further, the lengths of the first connecting rod and the second connecting rod are 10 - 30 mm; the radii of the first mounting ring and the second mounting ring are 20 - 40 mm. This is to ensure the stability and operability of the tooling. Description of the Drawings

[0029] The following is further detailed through specific implementation manners:

[0030] The reference numerals in the attached drawings of the specification include: machine body 1, working part 2, power transmission part 3, power distribution and control part 4, hammer rod 5, main cylinder end 6, hoist 7, sling 8, hoisting part 9, first clamping member 10, second clamping member 11, anti-slip layer 12, first lifting lug 13, second lifting lug 14, connection end 15, connection hole 16, compression bolt 17, first connecting rod 18, first mounting ring 19, second connecting rod 20, second mounting ring 21.

[0031] The embodiment is basically as shown in the attached Figure 3 figures: An auxiliary tooling for disassembling and assembling the forging hammer rod includes a first clamping member 10 and a second clamping member 11 provided at the hoisting part 9 of the hammer rod. In this embodiment, the hoisting part 9 of the hammer rod 5 is located 500 - 600 mm from the top of the hammer rod 5, or at 1 / 4 - 1 / 5 of the hammer rod length, mainly depending on the height of its effective space, so as to facilitate the installation operation and ensure the hoisting of the hammer rod can be completed at one time. Among them, the first clamping member 10 and the second clamping member 11 are oppositely installed on the periphery of the hoisting part 9 of the hammer rod 5 to clamp and fix the hammer rod 5 from the outside. The width L of the first clamping member 10 and the second clamping member 11 is 40 - 70 mm, or half of the hammer rod diameter, to improve the clamping force of the first clamping member 10 and the second clamping member 11, ensure the stability of clamping, and at the same time facilitate installation and storage.

[0032] As shown in the attached Figure 4As shown, the structures of the first clamping member 10 and the second clamping member 11 are the same, both being semi-circular arc-shaped structures with connecting ends 15 at both ends, and the arc radius is the same as the radius of the hoisted hammer rod. Specifically, during production, it is directly formed by cutting a circular sleeve with an inner hole diameter the same as the diameter of the hammer rod from the middle, so as to simplify the processing process, be more convenient for production and manufacturing, and at the same time ensure that the two clamping members can directly fit and fix with the hammer rod during installation. The first clamping member 10 and the second clamping member 11 are installed and connected through the connecting ends 15. Specifically, connecting holes 16 are respectively provided at the connection parts of the first clamping member 10 and the second clamping member 11. Compression bolts 17 for connection and fixation are also respectively provided on the connecting holes 16.

[0033] A layer of anti-slip layer 12 is also provided on the inner arc-shaped side walls of the first clamping member 10 and the second clamping member 11, so that when installed, it contacts the surface of the hammer rod 5, avoiding mutual displacement between the rod body of the hammer rod 5 and the clamping member, which affects the clamping stability and ensures the safety of the hoisting process. In this embodiment, the anti-slip layer 12 can be made by inlaying (coating) tin bronze QSn4-4-4 or adding a rubber pad or adding a copper pad, etc. The thickness of the anti-slip layer is 0.2 - 0.5 mm, which can avoid pinching the hammer rod while ensuring that it does not affect the installation due to being too thick, and at the same time can ensure the anti-slip effect.

[0034] A first lifting ear 13 is installed in the middle of the first clamping member 10 through bolts, and a second lifting ear 14 is installed in the middle of the second clamping member 11 through bolts. The first lifting ear 13 and the second lifting ear 14 are arranged opposite to each other to ensure balance and stability during the hoisting process.

[0035] Among them, the first lifting ear 13 includes a first connecting rod 18. A threaded hole for installing the first connecting rod 18 is provided in the middle of the first clamping member 10, and the first connecting rod 18 is vertically installed in the threaded hole in the middle of the first clamping member 10. A first mounting ring 19 is integrally formed at the end of the first connecting rod 18. A steel wire rope or a sling is installed through the first mounting ring 19 to ensure that the hoisting is in place and avoid damaging the hammer rod by the steel wire rope.

[0036] The second lifting ear 14 includes a second connecting rod 20. A threaded hole for installing the second connecting rod 20 is provided in the middle of the second clamping member 11, and the second connecting rod 20 is vertically installed in the threaded hole in the middle of the second clamping member 11. A second mounting ring 21 is integrally formed at the end of the second connecting rod 20. A steel wire rope or a sling is installed through the second mounting ring 21 to form a corresponding cooperative installation with the first mounting ring 19, making the hoisting more stable and balanced.

[0037] In this embodiment, the lengths of the first connecting rod 18 and the second connecting rod 20 are both set to 10 - 30 mm; to ensure the stability of the steel wire rope without scratching the hammer rod, and at the same time ensure convenient operation without affecting use and storage. And the radii of the first mounting ring 19 and the second mounting ring 21 are both set to 20 - 40 mm to facilitate the hoisting operation of the steel wire rope.

[0038] The specific implementation process is as follows:

[0039] As shown in the attached Figure 3 and the attached Figure 4 As shown, when in use, the first clamping member 10 and the second clamping member 11 are respectively clamped at the hoisting part 9 of the hammer rod, so that the anti-slip layers of the clamping members are respectively in contact with the rod body of the hammer rod. Then, two pressing bolts 17 are used to connect the two semi-circular clamping members into a circular sleeve and fixed on the hammer rod, wrapping the rod body of the hammer rod inside, and the nut of the pressing bolt is twisted with a wrench to press the two clamping members against each other. At this time, the tooling is firmly connected to the hammer rod.

[0040] Subsequently, the two ends of the steel wire rope or cloth bag are respectively hung on two opposite mounting rings and made symmetrical to each other, and then the hoisting of the hammer rod is completed at one time by using the crane hook. After use, the pressing bolts 17 are removed with a wrench, and the two clamping members can be separated naturally and removed respectively.

[0041] In this embodiment, the auxiliary tooling has a simple structure and is convenient for production. It can be processed and manufactured by using conventional materials (45# steel), with low production cost, easy installation and operation, high reusability, and can complete the hoisting of the hammer rod at one time, reducing the hoisting process and shortening the hoisting time, ensuring the safety and stability of hoisting, and improving the hoisting efficiency.

[0042] The above are only the embodiments of the present utility model. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail herein. It should be noted that for those skilled in the art, without departing from the technical solution of the present utility model, several deformations and improvements can be made, which should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicability of the patent.
