Description

An electrohydraulic hammer for flange forging Technical Field

[0001] This application relates to the technical field of flange forging equipment, and in particular to an electro-hydraulic hammer for flange forging. Background Technology

[0002] As an indispensable connecting element in piping systems, the manufacturing quality of flanges has a decisive impact on the overall safety and stability of the system. The forging process is particularly crucial in flange manufacturing. However, traditional forging methods often rely on manual operation for the flange flipping step. This method not only involves high physical exertion and low production efficiency, but also frequently threatens operator safety due to the complexity of the operating environment.

[0003] In modern industrial production, although automation technology has been applied in many fields, the degree of automation in the flange forging and turning process remains low. While some forging equipment has emerged on the market, significant manual assistance or forklift involvement is still required during flange turning, failing to achieve truly fully automated production. This not only affects production efficiency but also increases production costs and safety hazards.

[0004] In summary, existing flange forging equipment, especially the flipping step, still requires a large amount of manual labor and suffers from low automation and safety issues. Summary of the Invention

[0005] In order to improve the problems of low automation and insufficient safety in the flipping step of existing flange forging equipment, this application provides an electro-hydraulic hammer for flange forging.

[0006] This application provides an electro-hydraulic hammer for flange forging, which adopts the following technical solution:

[0007] An electro-hydraulic hammer for flange forging, comprising:

[0008] An electro-hydraulic hammer assembly, comprising a frame, hammer arm, hammer head, and base;

[0009] A clamping assembly for clamping a flange to be flipped;

[0010] A flipping assembly includes a positioning block, a steering block, a collision rod, a support rod, and collision rollers. The positioning block is slidably disposed vertically. The steering block has an isosceles triangle cross-section, and is rotatably connected to one end of the positioning block with a rotation center at one corner away from its hypotenuse. A horizontally disposed collision roller is fixedly connected to each of the other two corners of the steering block away from its rotation center. The collision rollers are located on the side of the steering block away from the positioning block. The support rod is vertically disposed. The collision rod is horizontally disposed and fixedly connected to the top end of the support rod. The clamping assembly is fixedly connected to the steering block.

[0011] A drive assembly for providing power for the vertical movement of the positioning block;

[0012] When the steering block is located below the collision rod, and the positioning block drives the steering block to move upward, the collision roller can collide with the collision rod, causing the steering block to flip, thereby causing the clamp assembly to flip.

[0013] By adopting the above technical solution, the flange can be placed on the base for forging. When it needs to be flipped after one side is forged, the flange can be clamped by the clamping assembly, and then the driving assembly drives the positioning block to move upward, which in turn drives the rotating block to move upward until the collision roller and the collision rod collide, causing the clamping assembly to flip, thereby flipping the flange. Then, the driving assembly drives the positioning block to move downward, and the flange is placed back on the base to achieve the purpose of flipping the flange. This method of flipping the flange does not require manual operation, improves the degree of automation, and reduces safety risks. The frame and hammer arm can provide structural support for the hammer head. The hammer head can forge the flange. The base can place the flange to be forged on the base. The positioning block can be equipped with a steering block. By rotating the steering block and the positioning block, and setting the collision roller and collision rod on the steering block, and sliding the positioning block in the vertical direction, the following can be achieved. When the steering block is below the collision rod, the upward movement of the positioning block can drive the steering block to move upward, thereby causing the collision roller to collide with the collision rod to achieve the flipping of the steering block; by fixing the clamping assembly to the steering block, the clamping assembly can be flipped when the steering block flips.

[0014] Optionally, a sliding assembly is also included; two support rods are provided, and the two support rods are symmetrically distributed with each other, and two collision rods are also provided, which are also symmetrically distributed with each other; both support rods are disposed on the sliding assembly; the sliding assembly is used to drive the support rods to slide in the horizontal direction.

[0015] By adopting the above technical solution, when no flipping is required, the steering block is located under one of the collision rods; when flipping is required, the drive assembly is activated to move the positioning block upward, which in turn moves the steering block upward until the collision roller collides with one of the collision rods. The collision roller causes the steering block to flip, which in turn causes the clamping assembly to flip. After the steering block flips, it moves downward, and the sliding assembly moves the support rod horizontally, positioning the steering block under the other collision rod, ready for the next flip. When there is only one collision rod, after one flip, the steering block needs to be manually rotated under the collision rod before the next flip can be performed. By adopting a design with two collision rods, it is not necessary to manually move the steering block under the collision rod after one flip. The steering block can be directly moved under the other collision rod through the sliding assembly, further improving the degree of automation, saving manpower, and reducing safety risks.

[0016] Optionally, the sliding assembly includes a base and a first slider; the base is horizontally arranged and has a rectangular cross-section, and a first groove is provided on the base, the length direction of the first groove being the same as the length direction of the base; the size of the first slider is adapted to the size of the first groove, and the first slider is slidably disposed in the first groove along the length direction of the first groove; the bottom end of the support rod is fixedly connected to the top surface of the first slider.

[0017] By adopting the above technical solution, the first slider can slide inside the base, thereby driving the support rod to slide together, which facilitates the movement of the two support rods. When the steering block flips and moves down, the collision roller cannot collide with the collision rod when the steering block moves up. By sliding the first slider to drive the support rod to slide, the other support rod is aligned with the steering block, so that when the steering block moves up, the collision roller can collide with the other support rod to form a flip.

[0018] Optionally, a guide block is also included. The guide block is fixedly disposed on the top surface of the first slider and located between the two support rods. The longitudinal section of the guide block is triangular. When the steering block moves downward, the steering block can abut against one side of the guide block, so that the guide block can drive the first slider to slide in the first groove, thereby driving the support rod to move.

[0019] By adopting the above technical solution, when the steering block completes its flipping and downward movement, it can abut against the guide block, thereby driving the guide block to move in the horizontal direction, which in turn drives the first slider and the support rod to move together, so that the steering block is aligned with another support rod in the vertical direction. There is no need to manually align the support rod with the steering block, which further improves the convenience of operation.

[0020] Optionally, the drive assembly includes a first hydraulic cylinder, which is a multi-stage hydraulic cylinder. The first hydraulic cylinder is vertically arranged, and the piston rod is located above the fixed end. The top end of the piston rod of the first hydraulic cylinder is fixedly connected to the positioning block.

[0021] By adopting the above technical solution, the first hydraulic cylinder can provide power for the positioning block to move in the vertical direction, thereby driving the steering block to move in the vertical direction.

[0022] Optionally, the drive assembly further includes a limiting post and a second slider. The limiting post is vertically positioned on one side of the first hydraulic cylinder. A second slide groove is formed on the side of the limiting post near the first hydraulic cylinder. The length direction of the second slide groove is vertical. The size of the second slider is adapted to the size of the second slide groove. The second slider is slidably disposed in the second slide groove in the vertical direction. The side of the second slider away from the limiting post is fixedly connected to the positioning block.

[0023] By adopting the above technical solution, the movement direction of the positioning block can be limited, so that the movement direction of the positioning block is parallel to the movement direction of the second slider, thereby improving the stability of the overall device. When the first hydraulic cylinder drives the positioning block to move in the vertical direction, the positioning block can simultaneously drive the second slider to move in the vertical direction within the second slide groove.

[0024] Optionally, the cross-section of the second slide groove is T-shaped, and the cross-section of the second slider is also T-shaped. When the second slider moves vertically within the second slide groove, it cannot detach from the second slide groove.

[0025] By adopting the above technical solution, the second slider can be limited within the second slide groove, so that when the second slider moves vertically within the second slide groove, it cannot fall out of the second slide groove, further enhancing the overall stability of the device.

[0026] Optionally, the positioning block has a hollow structure, and a steering rod fixedly connected to the steering block is rotatably disposed inside the positioning block. A first limiting rod is fixedly connected to the end face of the steering rod away from the steering block. A vertically disposed second limiting rod is fixedly connected to the bottom surface of the positioning block away from the steering block. An elastic rope is rotatably connected to the end of the first limiting rod away from the steering rod. The end of the elastic rope away from the first limiting rod is rotatably connected to the bottom end of the second limiting rod. When the elastic rope is in a balanced state, the first limiting rod is in a horizontal state, and the hypotenuse of the steering block is in a vertical state.

[0027] By adopting the above technical solution, when the clamp does not need to be flipped, the elastic rope is in a balanced state, the first limit rod is in a horizontal state, and the inclined side of the steering block is in a vertical state. At this time, the elastic force of the elastic rope can maintain the balance of the clamp. When the clamp is flipped, the collision roller collides with the collision rod, causing the steering block to flip, causing the steering rod to flip, causing the first limit rod to rotate, and causing the elastic rope to extend. When the steering block is flipped 90 degrees, the first limit rod is in a vertical state, and the elastic rope is extended to its longest state. When the steering block continues to flip, the contraction force of the elastic rope also causes the steering block to flip, which can improve the efficiency of the steering block returning to a balanced state. Through the setting of the first limit rod, the second limit rod, and the elastic rope, the overall stability, balance, and working efficiency of the device can be further improved.

[0028] Optionally, the clamping assembly includes a connecting component, a second hydraulic cylinder, a first transmission rod, a second transmission rod, a third transmission rod, and clamping rods. The second hydraulic cylinder is fixedly connected to the steering block via the connecting component, and its length direction is parallel to the length direction of the steering rod. Two first transmission rods are provided, located on opposite sides of the second hydraulic cylinder and fixedly connected to the side walls on opposite sides of the fixed end of the second hydraulic cylinder. Two second transmission rods are also provided, with one end of each second transmission rod hinged to the end of a first transmission rod away from the second hydraulic cylinder. Two third transmission rods are also provided, with one end of each third transmission rod hinged to the end of a second transmission rod away from the first transmission rod, and the end of each third transmission rod away from the second transmission rod hinged to the piston rod of the second hydraulic cylinder. Two clamping rods are also provided, with one end of each clamping rod fixedly connected to a third transmission rod. When the piston rod of the second hydraulic cylinder shortens, it can drive the two clamping rods to move towards each other; when the piston rod of the second hydraulic cylinder extends, it can drive the two clamping rods to move away from each other.

[0029] By adopting the above technical solution, the flange to be flipped can be clamped by the clamping rod, and the clamping rod can be powered by the second hydraulic cylinder. When the piston rod of the second hydraulic cylinder shortens, it can drive the two clamping rods to move towards each other, thereby clamping the flange. When the piston rod of the second hydraulic cylinder extends, it can drive the two clamping rods to move away from each other, thereby lowering the flange. Through the connection component, the fixed end of the second hydraulic cylinder can be fixedly connected to the steering block. The first transmission rod and its fixed connection to the fixed end of the second hydraulic cylinder provide structural support for the second transmission rod. The second transmission rod, with one end hinged to the end of the first transmission rod away from the second hydraulic cylinder, provides structural support for the third transmission rod. One end of the third transmission rod is hinged to the end of the second transmission rod furthest from the first transmission rod, and the other end is hinged to the piston rod of the second hydraulic cylinder. This allows the second transmission rod to rotate towards the second hydraulic cylinder when the piston rod of the second hydraulic cylinder extends, and simultaneously causes the third transmission rod to rotate towards the second hydraulic cylinder. Conversely, when the piston rod of the second hydraulic cylinder shortens, the second transmission rod to rotate away from the second hydraulic cylinder, and simultaneously causes the third transmission rod to rotate away from the second hydraulic cylinder. By using clamping rods and fixing them to the third transmission rod, when the third transmission rod rotates towards the second hydraulic cylinder, it causes the two clamping rods to move away from each other. Conversely, when the third transmission rod rotates away from the second hydraulic cylinder, it causes the two clamping rods to move closer to each other.

[0030] Optionally, the connecting component includes a connecting rod and a connecting block. The connecting rod is fixedly connected to the side of the steering block away from the positioning block, and the connecting block is fixedly connected to the end of the connecting rod away from the steering block. The second hydraulic cylinder is fixedly connected to the side of the connecting block away from the connecting rod. When the elastic rope is in a balanced state, the axial direction of the second hydraulic cylinder coincides with the rotation axis direction of the steering block.

[0031] By adopting the above technical solution, after the steering block has finished flipping, the elastic rope is in a balanced state regardless of which collision bar it is under, and the clamp can be positioned above the base.

[0032] In summary, this application includes at least one of the following beneficial technical effects:

[0033] 1. With the setup of the electro-hydraulic hammer assembly, clamp assembly, flipping assembly, and drive assembly, the flange can be placed on the base for forging. When one side needs to be flipped after forging, the clamp assembly can be used to clamp the flange, and then the drive assembly can drive the positioning block to move upward, which in turn drives the rotating block to move upward until the collision roller collides with the collision rod, causing the clamp assembly to flip, thereby flipping the flange. Then, the drive assembly can drive the positioning block to move downward, placing the flange back on the base to achieve the purpose of flipping the flange. This method of flipping the flange does not require manual operation, improves the degree of automation, and reduces safety risks.

[0034] 2. By setting up a sliding component and two support rods and a collision rod, it is no longer necessary to manually move the steering block to under the collision rod after each flip. The steering block can be moved directly to under the other collision rod through the sliding component, which further improves the degree of automation, saves manpower, and reduces safety risks.

[0035] 3. By setting the guide block, when the steering block completes its flipping and downward movement, it can abut against the guide block, thereby driving the guide block to move in the horizontal direction, which in turn drives the first slider and the support rod to move together, so that the steering block is aligned with the other support rod in the vertical direction. This eliminates the need for manual alignment of the support rod and the steering block, further improving the convenience of operation. Attached Figure Description

[0039] The present application will be further described in detail below with reference to Figures 1-2.

[0040] This application discloses an electro-hydraulic hammer for flange forging. Referring to Figures 1 and 2, the electro-hydraulic hammer for flange forging includes an electro-hydraulic hammer assembly 1, a clamping assembly 2, a flipping assembly 3, a driving assembly 4, and a sliding assembly 5. The electro-hydraulic hammer assembly 1 includes a frame 11, a hammer arm 12, a hammer head 13, and a base 14. The clamping assembly 2 is used to clamp the flange to be flipped. The flipping assembly 3 includes a positioning block 31, a turning block 32, a collision rod 35, a support rod 34, and a collision roller 33. The clamping assembly 2 is fixedly connected to the turning block 32. The driving assembly 4 is used to provide power for the vertical movement of the positioning block 31. The sliding assembly 5 is used to drive the support rod 34 to slide horizontally. When the turning block 32 is below the collision rod 35, and the positioning block 31 drives the turning block 32 to move upward, the collision roller 33 can collide with the collision rod 35, causing the turning block 32 to flip, thereby causing the clamping assembly 2 to flip, so as to achieve the purpose of flipping the flange.

[0041] Referring to Figure 1, there are two hammer arms 12, both of which are vertical in length and are arranged opposite each other in the horizontal direction. The frame 11 is fixedly installed at the top of the two hammer arms 12 and is fixedly connected to the hammer arms 12. The hammer head 13 is installed on the frame 11, and the frame 11 is provided with a hydraulic mechanism for providing power to the hammer head 13. The base 14 is located directly below the hammer head 13 and is used to place the flange to be forged. The flipping assembly 3 and the clamping assembly 2 are located on one side of the electro-hydraulic hammer assembly 1.

[0042] During operation, the flange to be forged is first placed on the base 14, and then the hammer 13 is started to forge the flange. When one side is forged, the flange needs to be flipped to forge the other side. At this time, the clamp assembly 2 is started to clamp the flange, and then the flipping assembly 3 is started to drive the clamp assembly 2 to flip, thereby driving the flange to flip. Then the flange is placed on the base 14 to complete the flipping of the flange. Then the hammer 13 is started again to forge the other side of the flange.

[0043] Referring to Figures 1 and 2, the drive assembly 4 includes a first hydraulic cylinder 41, a limiting post 42, and a second slider 43. The first hydraulic cylinder 41 is a multi-stage hydraulic cylinder, vertically arranged, with its fixed end on the ground and the piston rod above it. The top of the piston rod is fixedly connected to the positioning block 31. The limiting post 42 is vertically arranged and located on one side of the first hydraulic cylinder 41. A second slide groove 421 is provided on the side of the limiting post 42 closest to the first hydraulic cylinder 41. The length direction of the second slide groove 421 is vertical. The size of the second slider 43 is adapted to the size of the second slide groove 421. The second slider 43 slides vertically within the second slide groove 421. The cross-section of the second slide groove 421 is T-shaped, and the cross-section of the second slider 43 is also T-shaped, with its size adapted to the size of the second slide groove 421. The side of the second slider 43 away from the limiting post 42 is fixedly connected to the positioning block 31.

[0044] When the drive component 4 is working, the first hydraulic cylinder 41 is activated, which can drive the positioning block 31 to move in the vertical direction, and the second slider 43 can limit the movement direction of the positioning block 31.

[0045] Referring to Figures 1 and 2, the positioning block 31 is slidably arranged in the vertical direction; the longitudinal section of the steering block 32 is an isosceles triangle, and the steering block 32 is rotatably connected to the end of the positioning block 31 near the electro-hydraulic hammer assembly 1 with the corner away from its hypotenuse as the rotation center, and the direction of the rotation axis is the same as the length direction of the positioning block 31; a horizontally arranged collision roller 33 is fixedly connected to the other two corners of the side of the steering block 32 near the electro-hydraulic hammer assembly 1, and the length direction of the collision roller 33 is parallel to the rotation axis direction of the steering block 32; the support rod 34 is vertically arranged; the collision rod 35 is horizontally arranged and fixedly connected to the top of the support rod 34, and the length direction of the collision rod 35 is perpendicular to the length direction of the positioning block 31; the clamp assembly 2 is fixedly connected to the side of the steering block 32 away from the positioning block 31.

[0046] Referring to Figures 1 and 2, there are two support rods 34, which are arranged facing each other in the horizontal direction. There are also two collision rods 35, which are also arranged facing each other in the horizontal direction. Both support rods 34 are mounted on the sliding assembly 5. The sliding assembly 5 is used to drive the support rods 34 to slide in the horizontal direction.

[0047] Referring to Figures 1 and 2, the sliding assembly 5 includes a base 51 and a first slider 52. The base 51 is horizontally arranged and has a rectangular cross-section. The length direction of the base 51 is parallel to the length direction of the collision rod 35. A first groove 511 is formed on the top surface of the base 51, and the length direction of the first groove 511 is the same as the length direction of the base 51. The size of the first slider 52 is adapted to the size of the first groove 511. The first slider 52 is slidably disposed in the first groove 511 along the length direction of the first groove 511. The bottom ends of the two support rods 34 are fixedly connected to the two ends of the top surface of the first slider 52, respectively.

[0048] Referring to Figures 1 and 2, a guide block 6 is fixedly disposed on the top surface of the first slider 52, and the guide block 6 is located between the two support rods 34. The longitudinal section of the guide block 6 is an isosceles triangle, with its hypotenuse facing downwards and fixedly connected to the top surface of the first slider 52. When the steering block 32 moves downwards, the steering block 32 can abut against the side of one side of the guide block 6, so that the guide block 6 can drive the first slider 52 to slide within the first slide groove 511, thereby driving the support rods 34 to move.

[0049] Referring to Figures 1 and 2, the positioning block 31 has a hollow structure. Inside the positioning block 31, a steering rod 36 is rotatably connected to the steering block 32. The length direction of the steering rod 36 is the same as that of the positioning block 31. A first limiting rod 37 is fixedly connected to the end face of the steering rod 36 away from the steering block 32. A vertically arranged second limiting rod 38 is fixedly connected to the bottom surface of the positioning block 31 away from the steering block 32. An elastic rope 39 is rotatably connected to the end of the first limiting rod 37 away from the steering rod 36. The end of the elastic rope 39 away from the first limiting rod 37 is rotatably connected to the bottom end of the second limiting rod 38. When the elastic rope 39 is in a balanced state, the first limiting rod 37 is in a horizontal state, and the hypotenuse of the steering block 32 is in a vertical state.

[0050] When one side of the flange is forged and needs to be flipped to the other side, the clamping assembly 2 is activated to clamp the flange. At this time, the positioning block is directly below a collision rod 35. The first hydraulic cylinder 41 is activated to move the positioning block 31 upward, thereby moving the steering block 32 upward until the collision roller 33 collides with the collision rod 35, causing the steering block 32 to flip, which in turn rotates the steering rod 36, causing the first limit rod 37 to rotate, and causing the elastic rope 39 to extend. When the steering block 32 is flipped 90 degrees, the first limit rod 37 is in a vertical position, and the elastic rope 39 is extended to its maximum length. As the steering block 32 continues to flip, the contraction force of the elastic rope 39 also drives the steering block 32 to flip, returning it to a balanced state. The clamp assembly 2 also flips, and the flange flips along with it. After the flipping is completed, the positioning block 31 is driven to move downward by the first hydraulic cylinder 41 until the steering block 32 contacts the guide block 6, which then moves the guide block 6 horizontally until the steering block 32 is directly below another collision rod 35 to be collided with. The flange is then lowered, and the other side of the flange is forged. The forging of the front and back sides of each flange is repeated using the above steps.

[0051] Referring to Figures 1 and 2, the clamp assembly 2 includes a connecting component 21, a second hydraulic cylinder 22, a first transmission rod 23, a second transmission rod 24, a third transmission rod 25, and a clamping rod 26. The second hydraulic cylinder 22 is fixedly connected to the steering block 32 via the connecting component 21, and its length direction is parallel to the length direction of the steering rod 36. Two first transmission rods 23 are provided, located on both sides of the second hydraulic cylinder 22, and fixedly connected to the side walls on both sides of the fixed end of the second hydraulic cylinder 22. Two second transmission rods 24 are also provided, with one end of each second transmission rod 24 hinged to the end of a first transmission rod 23 away from the second hydraulic cylinder 22. Two third transmission rods 25 are also provided, with one end of each third transmission rod 25 hinged to the end of a second transmission rod 24 away from the first transmission rod 23. Both ends are hinged to the piston rod of the second hydraulic cylinder 22; two clamping rods 26 are also provided, and one end of each clamping rod 26 is fixedly connected to a third transmission rod 25; when the piston rod of the second hydraulic cylinder 22 shortens, it can drive the two clamping rods 26 to move towards each other; when the piston rod of the second hydraulic cylinder 22 extends, it can drive the two clamping rods 26 to move away from each other; the connecting component 21 includes a connecting rod 211 and a connecting block 212. The connecting rod 211 is fixedly connected to the side of the steering block 32 away from the positioning block 31, and the connecting block 212 is fixedly connected to the end of the connecting rod 211 away from the steering block 32. The second hydraulic cylinder 22 is fixedly connected to the side of the connecting block 212 away from the connecting rod 211. When the elastic rope 39 is in a balanced state, the axial direction of the second hydraulic cylinder 22 coincides with the rotation axis direction of the steering block 32.

[0052] When the clamp assembly 2 is working, the piston rod of the second hydraulic cylinder 22 shortens, which can drive the two clamping rods 26 to move toward each other, thereby clamping the flange; the piston rod of the second hydraulic cylinder 22 extends, which can drive the two clamping rods 26 to move toward each other, thereby lowering the flange.

[0053] The implementation principle of an electro-hydraulic hammer for flange forging according to an embodiment of this application is as follows: During operation, the flange to be forged is first placed on the base 14, and then the hammer head 13 is started to forge the flange. When one side is forged, the flange needs to be flipped to forge the other side. First, the first hydraulic cylinder 41 is started, which drives the positioning block 31 to move vertically, so that the clamping rod 26 and the flange are on the same horizontal plane. Then, the second hydraulic cylinder 22 is started, which shortens the piston rod of the second hydraulic cylinder 22, driving the two clamping rods 26 to move towards each other, clamping the flange. At this time, the clamping block is directly below a collision rod 35. The first hydraulic cylinder 41 is started, which drives the positioning block 31 to move upward, thereby driving the steering block 32 to move upward until the collision roller 33 collides with the collision rod 35, causing the steering block 32 to flip, driving the steering rod 36 to rotate, and driving the first limit rod 37 to rotate. The elastic rope 39 is extended. When the steering block 32 is rotated 90 degrees, the first limit rod 37 is in a vertical state, and the elastic rope 39 is extended to its longest state. As the steering block 32 continues to rotate, the contraction force of the elastic rope 39 also drives the steering block 32 to rotate, so that the steering block 32 returns to the equilibrium state. The clamp assembly 2 also rotates, and the flange also rotates together. After the rotation is completed, the positioning block 31 is driven to move downward by the first hydraulic cylinder 41 until the steering block 32 contacts the guide block 6, and the guide block 6 is driven to move horizontally until the steering block 32 is directly below the other collision rod 35 to be collided with. The second hydraulic cylinder 22 is activated, so that the piston rod of the second hydraulic cylinder 22 extends, driving the two clamping rods 26 to move in a direction away from each other, and the flange is lowered to forge the other side of the flange. The above steps are repeated for forging the front and back sides of each flange.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
