Description

Technical Field

[0001] The invention relates to the technical field of forging equipment, and in particular to a hook head positioning key disassembly device and a disassembly method thereof. Background Art

[0002] Forging hammer is a highly efficient forging process equipment, which uses air pressure or hydraulic transmission mechanism to make the falling part quickly accumulate kinetic energy, and apply this energy to the forging in a very short time, so as to complete various forging operations. Figure 1 As shown, the body of the forging hammer generally includes hammering components such as anvil 1, hammer arm 2, crossbeam 3, power head 4 and hammer head die 6. The two ends of the crossbeam are mounted on the hammer arm, and the connecting mechanism of the power head is fixed in the middle.

[0003] The hook head positioning key 5 is a key component in the forging hammer body, which is mainly used to fix the hammer arm and the crossbeam to prevent their longitudinal displacement and prevent the lateral relative displacement between them. Its performance directly affects the strength and accuracy of the entire forging hammer.

[0004] The hook head positioning key currently used is mainly composed of a square key body and a hook head at the tail end. The square key body is used to fix the hammer arm and the beam to prevent their relative displacement, and the hook head part mainly cooperates with other auxiliary structures to fix the square key body to prevent it from withdrawing.

[0005] However, due to the special working conditions of the forging hammer, the vibration and shaking of the hammer body caused by the reciprocating forging of the hammer head can easily cause the hook head positioning key to slip out of the original slot, affecting the processing efficiency of the forging hammer, and it can also easily cause a high-altitude fall accident, causing production safety problems. Therefore, the current hook head positioning key will be equipped with a fixing device to prevent high-altitude fall, usually by installing a fastening bolt on the positioning key to firmly fix the hook head positioning key on the hammer arm, thereby eliminating the hook head part.

[0006] However, due to the vibration and shaking of the hammer body caused by frequent forging, the gap between the hammer arm and the crossbeam often needs to be adjusted. At this time, the hook head positioning key needs to be removed, and a new hook head positioning key needs to be matched according to the gap size to meet the forging hammer assembly requirements. However, in order to prevent the hook head positioning key from slipping, the positioning key is fixed, which makes its removal very cumbersome. Generally, it is necessary to remove other auxiliary components such as the upper power head of the forging hammer first, then lift the crossbeam away, and finally remove the fastening bolts to replace the hook head positioning key. As a result, the entire removal process requires a large workload, a long operation cycle, high disassembly and assembly costs, and great safety risks. Summary of the invention

[0007] The present invention aims to provide a hook positioning key disassembly device and a disassembly method thereof, so as to solve the problems that the existing hook positioning key disassembly and assembly process is complicated, the cycle is long, the disassembly and assembly cost is high and there are safety risks.

[0008] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a hook head positioning key disassembly device, comprising a main board, which is a rectangular steel plate; a ball-shifting inclined plate is provided at one end of the main board, and the inclination angle of the ball-shifting inclined plate is 30 to 60 degrees; a handle is provided at the other end of the main board; a pin hole block is also provided on the main board, and the pin hole block is provided at one-third of the distance from the handle; the diameter of the pin hole block is 8 to 12 mm.

[0009] Furthermore, it also includes a positioning key structure used in conjunction with the disassembly device; the positioning key structure includes a positioning key body, a wedge slot is provided at one end of the positioning key body, and a ball-locking slot is provided at the connection between the wedge slot and the positioning key body; a limiting hole is provided on the hammer arm of the forging hammer, an elastic member is provided in the limiting hole, and a ball head positioning column is provided on the elastic member; the ball head positioning column abuts against the ball-locking slot.

[0010] Furthermore, the width of the main board is consistent with the width of the wedge slot, which is 1 / 4-1 / 3 of the diameter of the ball head of the ball head positioning column. This ensures that the main board can move in the wedge slot and that the width and strength of the main board are met to the maximum extent to assist in disassembly, while the wedge slot can limit the movement of the ball head positioning column to ensure the stability of the positioning key.

[0011] Furthermore, the height of the main board is consistent with the ball head radius of the ball head positioning column, so that it can match the wedge slot and gradually press the ball head positioning column downward during insertion, ensuring smoother and more convenient operation.

[0012] Furthermore, the length of the main board is greater than the length of the wedge slot, so as to ensure that after the disassembly device is inserted into the wedge slot, its pin hole can be aligned with the latch hole, and the corresponding handle can be placed outside the positioning key, so as to facilitate relative fixing and push-pull operations and reduce the work intensity.

[0013] Furthermore, a latch hole is provided on the positioning key body; the latch hole is provided at one end of the wedge insertion slot and is arranged opposite to the latch hole stop.

[0014] Furthermore, it also includes a pin, which is arranged in the pin hole and penetrates into the pin hole.

[0015] Furthermore, the handle is a cylindrical rod with a diameter of 10 to 20 mm, which is convenient for hand-held operation, and can achieve the disassembly force under a relatively low force, thereby reducing the difficulty of disassembly.

[0016] At the same time, the present invention also provides a hook head positioning key disassembly method, which is applied to the above hook head positioning key disassembly device, and includes the following steps:

[0017] Step 1: Place the ball-push plate of the disassembly device mainboard downward and insert it into the wedge slot;

[0018] Step 2: The ball-moving inclined plate contacts the ball head of the ball head positioning column under the push of the force, and pushes the ball head positioning column and the elastic member downward one by one until the main board completely presses the ball head positioning column, so that the top of the ball head positioning column is flush with the bottom of the positioning key body;

[0019] Step 3: Insert the pin from above the latch hole and pass it through the latch hole to connect and fix the positioning key to the mainboard;

[0020] Step 4: Pull the handle outward to pull out the disassembly device and the positioning key body together to complete the removal of the positioning key.

[0021] Furthermore, the diameter of the ball-locking groove is one third of the width of the positioning key body.

[0022] The principles and advantages of this solution are:

[0023] In the application of large-scale forging hammer equipment, the stability of the locating key structure is of vital importance. In view of the large size of the equipment and the huge force generated during operation, the traditional design concept tends to adopt complex or stable fixed structures to install the locating keys to ensure stability, and abandons the structural form that seems to have no fixed connection. Because this kind of seemingly loose structure is very likely to cause relative movement between the locating key and related components due to insufficient force, and it is impossible to achieve a stable working state. Just like the traditional hook-type locating key, in order to ensure its stability, it is necessary to further set auxiliary parts such as welded parts for reinforcement on the hook part. Therefore, in order to ensure that it can achieve a stable effect in one step, a fixed structure is currently mostly used to achieve a stable installation of the locating key to prevent it from loosening.

[0024] However, although this overly fixed structure ensures stability, it also brings great trouble to the dismantling work. Due to its tight structure, dismantling often requires multiple lifting operations, which not only greatly prolongs the dismantling cycle, but also significantly increases the safety risks during the complex lifting process.

[0025] This solution breaks through the traditional logic of thinking and adopts a movable abutment structure that seems to have no relatively fixed connection. In actual application, this structure can not only achieve effective limit fixation and achieve the same stability effect as the traditional fixed structure, but also improve the flexibility of the positioning key disassembly. As a result, this solution can directly use the disassembly device for rapid disassembly. Therefore, the disassembly device in this solution has a simple structure, flexible operation, and low safety risk. Without the need to remove other auxiliary parts, the positioning key can be quickly disassembled. The difficulty of disassembly of the positioning key is greatly reduced, the disassembly cycle is shortened, and the disassembly of the positioning key can be completed by a single person, which greatly reduces labor costs and disassembly costs, improves disassembly efficiency, reduces safety risks, and has a wide range of applicability.

DETAILED DESCRIPTION

[0034] The following is further described in detail through specific implementation methods:

[0035] Embodiment 1

[0036] The hook head positioning key disassembly device in this embodiment is a reusable disassembly auxiliary tool with a simple structure and is more convenient for disassembly operation. The positioning key can be directly taken out and replaced without removing other parts of the forging hammer, which greatly reduces the difficulty of disassembly, shortens the disassembly process, reduces the disassembly cycle, improves the disassembly efficiency, and effectively reduces the disassembly cost. In this embodiment, the positioning key disassembly device needs to be used in conjunction with the positioning key structure, wherein the positioning key structure used is as shown in the attached Figure 2 As shown, the positioning key structure includes a positioning key body 7 which is an overall rectangular structure. A wedge slot 8 is provided at one end of the positioning key body 7 , and a slope surface 9 is provided at the other end of the positioning key body 7 .

[0037] A ball-locking groove 19 is provided at the connection between the wedge slot 8 and the positioning key body 7. In this embodiment, the ball-locking groove 19 is a circular groove that is concave downward. Figure 3As shown, the diameter of the ball slot 19 is set to one third of the width of the positioning key body 7. A bayonet hole 10 is also provided on the positioning key body 7. The bayonet hole 10 is vertically arranged at one end of the wedge slot 8 and communicated with the wedge slot 8. In this embodiment, the bayonet hole 10 is set to be a cylindrical hole with a diameter of 10 mm.

[0038] At the same time, combined with Figure 4 As shown, a limiting hole 11 is further provided on the hammer arm 2 of the forging hammer, an elastic member 12 is installed in the limiting hole 11, and a ball head positioning column 13 is installed on the elastic member 12. In this embodiment, the elastic member 12 is a spring structure, and the ball head positioning column 13 can move up and down in the limiting hole 11 under the action of the spring, and when the ball head positioning column 13 moves upward, its ball head can abut against the ball clamping groove 19, so as to limit and fix the positioning key, and also make the ball clamping groove 19 just able to accommodate the ball head to move up and down.

[0039] In this embodiment, the hook head positioning key disassembly device is as shown in the attached Figure 5 As shown, it includes a main board 14. In this embodiment, the main board 14 is a rectangular steel plate. Figure 6 As shown, the width of the main board 14 is consistent with the width of the wedge slot 8, and both are 1 / 4 to 1 / 3 of the diameter of the ball head of the ball head positioning column 13. The height of the main board 14 is consistent with the ball head radius of the ball head positioning column 13, so that it can just move in the wedge slot 8. The length of the main board 14 needs to be greater than the length of the wedge slot 8. The wedge slot 8 can just accommodate the insertion of the main board 14, and the main board 14 can both limit the movement of the ball head positioning column 13 and maximize the width and strength of the main board 14 to assist in convenient disassembly.

[0040] A ball-shifting inclined plate 15 is provided at one end of the main board 14. In the present embodiment, the inclination angle of the ball-shifting inclined plate 15 is set to 30 to 60 degrees, so that when the main board 14 is inserted into the wedge slot 8, it is ensured that the ball-shifting inclined plate 15 can gradually contact the ball head positioning column 13 and gradually push the ball head positioning column 13 downward, so that the ball head positioning column 13 can smoothly enter the limiting hole 11 and be flush with the bottom of the positioning key body 7.

[0041] A handle 16 is integrally formed at the other end of the main board 14. In this embodiment, the handle 16 is a cylindrical rod with a diameter of 10 to 20 mm, and the main board 14 is arranged in the middle of the handle 16, so that the main board 14 can be pushed and pulled by the handle 16, which is more convenient for handheld operation. A latch hole 17 is also provided on the main board 14. In this embodiment, the latch hole 17 is arranged at one-third of the distance from the handle 16, and when the main board 14 is inserted into the wedge slot 8, it can be arranged opposite to the bayonet hole 10 of the positioning key body. In this embodiment, the diameter of the latch hole 17 can be set to 8 to 12 mm, and can be set to 10 mm, which is consistent with the diameter of the bayonet hole 10.

[0042] At the same time, it also includes a pin 18. In this embodiment, the pin 18 is a cylindrical pin with a diameter no greater than the diameter of the pin hole 17. It can be movably arranged in the pin hole 10 and penetrate into the pin hole 17 to fix the positioning key body 7 and the disassembly device mainboard in the horizontal direction.

[0043] In this embodiment, a dismantling device adapted to the positioning key structure is used. Through the ball-pick inclined plate 15 and the reserved wedge slot 8, the positioning key can be quickly dismantled without the need to dismantle other auxiliary parts such as the forging hammer power head, which greatly reduces the difficulty and workload of dismantling. A convenient, efficient and low-cost dismantling method is achieved, and only one person is required to complete it, effectively reducing labor costs and operating costs, while reducing operating safety risks, and having strong reusability.

[0044] Embodiment 2

[0045] In this embodiment, a method for disassembling a hook head positioning key is provided. It is applied to the above-mentioned hook head positioning key disassembly device. Figure 7 As shown, the following steps are included:

[0046] S1, place the ball-push plate of the disassembly device mainboard downward and insert it into the wedge slot.

[0047] In this embodiment, the ball-moving inclined plate 15 of the main board of the disassembling device is firstly placed downward, and then the main board 14 is inserted into the installed wedge slot 8 and pushed inward with force.

[0048] S2, the ball-moving inclined plate 15 will first contact the ball head of the ball head positioning column 13 under the action of the force, and under the action of its tilt angle, it will gradually push the ball head positioning column 13 downward, thereby driving the elastic member 12 to be compressed and moved downward until the main board 14 completely presses the ball head positioning column 13, so that the top of the ball head positioning column 13 is flush with the bottom of the positioning key body.

[0049] At this time, the main board 14 will abut against the top of the wedge slot 8, and the upper and lower surfaces will abut against the positioning key and the hammer arm respectively to form a relative fixation, thereby pressing the ball head positioning column 13 into the limit hole 11, and making the pin hole stop 17 directly opposite to the bottom of the pin hole 10, and the handle 16 is placed on the outside of the positioning key as a whole.

[0050] S3, insert the pin 18 from the top of the latch hole 10 and penetrate into the pin hole 17, fix the pin 18 from the bottom end, so that the positioning key is connected and fixed to the main board 14.

[0051] In this embodiment, the length of the latch pin 18 needs to be greater than the sum of the thickness of the positioning key and the main board, so that the positioning key and the disassembly device can be connected together in the lateral direction through the latch pin 18, thereby fixing the two relatively.

[0052] S4, pull the handle 16 outwards to pull out the disassembly device and the positioning key body 7 together, and complete the removal of the positioning key.

[0053] Since the main board 14 of the disassembly device compresses the ball head positioning column 13 into the limiting hole 11, the limiting fixing effect of the positioning key is removed. Therefore, when the main board 14 is pulled, the positioning key can be smoothly removed from between the hammer arm 2 and the crossbeam 3, and the removal of the positioning key can be quickly completed.

[0054] In this embodiment, the positioning key can be quickly disassembled by the disassembly device without the need to additionally hoist and disassemble other auxiliary parts, which greatly reduces the difficulty and workload of the disassembly. The overall disassembly process is simple and fast, and can be completed by one person, reducing the safety risk and cost of disassembly, and effectively improving the disassembly efficiency.

[0055] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
