Description

Technical Field

[0001] This invention relates to the field of folding and punching technology, and more specifically, to an integrated device for folding and punching U-shaped parts. Background Technology

[0002] Folding and punching are the core processes in the processing of U-shaped parts. The folding process involves continuously rolling and pressing the flat blank to form a U-shaped contour that meets the dimensional requirements. The punching process requires machining mounting holes or positioning holes at specific locations on the U-shaped part according to assembly requirements. In order to improve processing efficiency, integrated equipment for folding and punching U-shaped parts is gradually replacing the traditional step-by-step processing mode. This integrated processing method not only reduces the transfer time of workpieces between different equipment, but also realizes the continuity and automation of the processing flow.

[0003] The existing U-shaped part folding and punching integrated equipment integrates the folding station and the punching station, realizing the continuous processing from blank to formed U-shaped part with holes. The equipment first transports the flat blank to the folding station through the feeding mechanism. According to the cross-sectional dimensions of the U-shaped part, it completes the step-by-step extrusion folding and forming. After the folding is completed, the U-shaped part is cut to the required length. Then the cut U-shaped part is transferred to the punching station. The punching station is equipped with a support structure that is adapted to the inner cavity of the U-shaped part. The whole structure is in the shape of the U-shaped part and can provide support for the U-shaped part during the punching process. Then the punch is controlled to move to complete the punching process of the U-shaped part.

[0004] However, in the actual processing flow of U-shaped parts, after the folding process, the workpiece is cut according to production needs to obtain a single U-shaped part that meets the length requirements. Processing obstacles often occur in this connection link. Due to the influence of factors such as material stress release, processing equipment accuracy deviation, or uneven clamping force during the folding and cutting process, the end of the U-shaped part is prone to micro-deformation, such as side expansion and port tilting. The support structure in the drilling station is a solid and fixed contour design, which has high requirements for the insertion posture and dimensional accuracy of the U-shaped part. When a deformed U-shaped part is fed in, its deformed part will interfere with the support structure, causing the workpiece to be unable to be inserted smoothly. This not only requires the operator to stop the machine for manual adjustment, but may also cause the equipment to jam, reducing the overall processing efficiency. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an integrated device for folding and punching U-shaped parts.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an integrated device for folding and punching U-shaped parts, including a base.

[0007] Folding assembly, used for continuous folding of U-shaped raw materials.

[0008] The punching assembly is used to cut U-shaped parts to a fixed length after folding.

[0014] The present invention is further configured such that: the punching component is located between the folding component and the connecting component; the punching component includes a support seat mounted on the top of the base; a driving cylinder is obliquely mounted on the top of the support seat; an inclined groove is formed on the side wall of the support seat; a cutter is slidably connected inside the inclined groove; the piston rod of the driving cylinder is connected to the cutter; the cutter is located on the side of the support seat away from the folding component; and both the side wall of the support seat and the side wall of the cutter are provided with contoured through grooves.

[0015] The present invention is further configured such that: two V-shaped baffles are symmetrically installed on the top of the rolling conveyor mechanism; a roller pressing mechanism is installed on the top of the second wedge seat; the roller pressing mechanism extends to the top of the rolling conveyor mechanism and is located between the V-shaped baffles and the guiding mechanism; a positioning mechanism is also installed on the top of the second wedge seat; the positioning mechanism is located below the rolling conveyor mechanism and below the roller pressing mechanism.

[0016] The present invention is further configured such that: the roller pressing mechanism includes a roller pressing frame installed on the top of the second wedge-shaped seat and a lifting cylinder installed vertically on the top of the roller pressing frame; a guide rail is installed on one side of the roller pressing frame; a slider is slidably connected on the guide rail; the piston rod of the lifting cylinder is connected to the slider; and a pressure roller is rotatably connected to the bottom of the slider.

[0017] The present invention is further configured such that: an arc-shaped portion is provided on the top of the side of the guide groove facing the rolling conveying mechanism, and an extension block is connected to the side of the guide block away from the rolling conveying mechanism.

[0018] The present invention is further configured such that: the positioning mechanism includes two carrier rods slidably connected to the top of the second wedge-shaped seat, each carrier rod having a plurality of columns equidistantly arranged on its top, and each column having a roller rotating on its outer side wall.

[0019] One side of each of the two carrier rods is connected to a guide groove, and a sliding column is slidably connected inside the guide groove. A hinge rod is hinged to the side wall of the carrier rod away from the guide groove. The end of the hinge rod away from the corresponding carrier rod is connected to the sliding column on the other carrier rod. The two hinge rods are hinged to each other. A two-way hydraulic cylinder is installed on the top of the first wedge seat. The two piston rods of the two-way hydraulic cylinder are connected to the two carrier rods.

[0020] The present invention is further configured such that: a swing plate is hinged to the top of each of the carrier rods and the end near the bidirectional hydraulic cylinder; a fixed seat is installed on the side wall of the end of the carrier rod away from the bidirectional hydraulic cylinder; a telescopic cylinder is installed on the top of each fixed seat; and the piston rod of the telescopic cylinder is hinged to the top of the corresponding swing plate.

[0021] The invention is further configured such that: the drilling assembly includes a frame mounted on the top of the base and located on the side away from the connecting assembly; a mounting bracket and a drilling seat are mounted on the top of the frame; the drilling seat is located inside the mounting bracket; a drilling through slot is formed on one side of the drilling seat; two horizontal drilling cylinders are horizontally mounted on both sides of the mounting bracket; three vertical drilling cylinders are mounted on the top of the mounting bracket; and through holes for drilling are formed on the top and side walls of the drilling through slot, extending into the interior of the drilling through slot.

[0022] In summary, this application includes at least one of the following beneficial technical effects: (1) By setting up a guide section, the V-shaped baffle of the connecting component is used for initial positioning. The roller pressing mechanism clamps and conveys the arc-shaped part and the guide section are adjusted in a targeted manner. That is, the guide section is adjusted during the process of the U-shaped part moving into the guide groove, so that the U-shaped part that has shrunk inwards returns to its normal shape. The wedge seat is tilted upwards and the distance between the extension block is shortened by using the transfer cylinder. This achieves the purpose of feeding the U-shaped part into the perforated through groove without interference, and solves the problem of material jamming and manual adjustment caused by the interference between the deformation and the perforated through groove of the U-shaped part after the edge is cut off.

[0023] (2) The positioning mechanism drives the carrier rod to slide synchronously through the bidirectional hydraulic cylinder, and uses the roller to roll and squeeze the side wall of the U-shaped part, which alleviates the outward expansion of the side and avoids hard contact with the inlet of the punched through slot. This solves the problems of the workpiece being difficult to insert, easy to deform or wear of the support structure, and ensures smooth conveying.

[0024] (3) By using the carrier rod to clamp and position to correct the positional deviation of the U-shaped part after punching, and cooperating with the telescopic cylinder to drive the swing plate to adaptively squeeze and prevent expansion again during transportation, the roller pressing mechanism can stably obtain the workpiece and send it into the punched through slot, further reducing interference.

[0043] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0045] Please see Figures 1-17 The present invention provides the following technical solutions: Example 1, see Figure 1 and Figure 2 A U-shaped part folding and punching integrated device includes a base 1, and a folding component 2 is installed on the top of the base 1. The folding component 2 is used to continuously fold the U-shaped part material.

[0046] See Figure 2 The folding assembly 2 includes a workbench 21 mounted on the top of the base 1. Multiple sets of rolling and folding mechanisms 22 are mounted on the top of the workbench 21. The multiple sets of rolling and folding mechanisms 22 are arranged at equal intervals on the top of the workbench 21. When the U-shaped raw material plate passes through the multiple sets of rolling and folding mechanisms 22, the plate is gradually rolled and folded by the multiple sets of rolling and folding mechanisms 22 to form a U-shaped part.

[0047] See Figure 2 and Figure 3 Each set of folding mechanisms 22 includes two support seats 221 symmetrically mounted on the top of the worktable 21. A slide seat 222 is slidably connected to the top of each support seat 221. A rotating shaft 223 is rotatably connected between the two slide seats 222 and between the two support seats 221. A roller group 224 for folding is sleeved on the outer wall of each rotating shaft 223. The roller group 224 is adapted to the U-shaped part forming process. An external drive device, such as a servo motor, is connected to the end of the rotating shaft 223. Without specific limitations, the driving device applies a driving force to the rotating shaft 223, causing the roller group 224 to rotate. The two opposing roller groups 224 rotate in opposite directions. When the U-shaped material plate reaches the position of the roller group 224, the roller group 224 rotates on the outer wall of the rotating shaft 223, thereby rolling the U-shaped material plate to form a U-shape. The slide 222 can slide on the top of the bearing seat 221 to adjust the distance between the two roller groups 224, thereby adapting to U-shaped material of different thicknesses.

[0048] See Figure 1 A cutting assembly 3 is installed on the top of the base 1. The cutting assembly 3 is located on one side of the folding assembly 2. The cutting assembly 3 is used to cut the U-shaped part to a fixed length after it has been folded by the folding assembly 2. The specific structure of the cutting assembly 3 is as follows: See Figure 1 , Figures 4-5 The punching assembly 3 includes a support base 31 mounted on the top of the base 1. A drive cylinder 33 is mounted at an angle on the top of the support base 31. An inclined groove is provided on the side wall of the support base 31. A cutter 32 is slidably connected inside the inclined groove. The piston rod of the drive cylinder 33 is connected to the cutter 32. The cutter 32 is located on the side of the support base 31 away from the folding assembly 2. A contouring groove 34 is provided on both the side wall of the support base 31 and the side wall of the cutter 32. The folded U-shaped piece passes through the contouring groove 34 and through the contouring groove 34 to a predetermined length. Then, the drive cylinder 33 pushes the cutter 32 to slide inside the inclined groove, causing the fixed-length U-shaped piece to move a certain distance with the cutter 32, thereby punching and cutting the fixed-length U-shaped piece.

[0049] See Figure 1 The base 1 is also equipped with a punching component 5. The punching component 5 is located on the side of the punching component 3 away from the folding component 2. The punching component 5 is used to punch holes in the U-shaped parts that are conveyed after being cut to a fixed length.

[0050] See Figure 6 The specific structure of the punching component 5 is as follows: The punching assembly 5 includes a frame 51 mounted on one side of the top of the base 1. A mounting bracket 52 and a punching seat 54 are mounted on the top of the frame 51. The punching seat 54 is located inside the mounting bracket 52. A punching slot 55 is provided on one side of the punching seat 54. Two horizontal punching cylinders 53 are horizontally mounted on both sides of the mounting bracket 52. Three vertical punching cylinders 56 are mounted on the top of the mounting bracket 52. Through holes for punching are provided on the top and side walls of the punching slot 55. The through holes extend into the interior of the punching slot 55. Punches are mounted on both the horizontal punching cylinders 53 and the vertical punching cylinders 56. A traction device is provided at the discharge port of the punching assembly 5. This traction device can be composed of an electric slide rail and an electric gripper. The electric gripper slides on the top of the electric slide rail. The electric slide rail can drive the electric gripper to move. The electric gripper is used to clamp the U-shaped part.

[0051] After being cut to a fixed length, the U-shaped part extends into the interior of the punching slot 55, and the end of the U-shaped part penetrates into the interior of the punching slot 55 and is held by an electric gripper. Subsequently, the electric slide rail drives the electric gripper to move, thereby pulling the U-shaped part. The position of the U-shaped part to be punched moves into the interior of the punching slot 55. At this time, the vertical punching cylinder 56 and the horizontal punching cylinder 53 cooperate to cause the punches installed on the vertical punching cylinder 56 and the horizontal punching cylinder 53 to perform punching operations on the position of the U-shaped part to be punched. The size of the punches installed on the vertical punching cylinder 56 and the horizontal punching cylinder 53 can be installed and replaced as needed, so that specific mounting holes or positioning holes can be punched on the U-shaped part.

[0052] Example 2, see Figure 16 and Figure 17 In the actual processing flow of U-shaped parts, after the folding process is completed, the workpiece is cut according to the production requirements to obtain a single U-shaped part that meets the length requirements. Processing obstacles often occur in this connection link. During the folding and cutting process, the U-shaped part is affected by factors such as material stress release, processing equipment accuracy deviation or uneven clamping force. Although the basic shape of the U-shaped part is not affected, its whole and sides are very prone to micro deformation, such as side expansion and port tilting.

[0053] The punching seat 54 in the punching station has a slot structure, and the punching through slot 55 has a fixed contour design. It has high requirements for the insertion posture and dimensional accuracy of the U-shaped part. When the U-shaped part with overall deformation is fed in, its deformed part will interfere with the opening position of the punching through slot 55 on the punching seat 54, causing the U-shaped part to be unable to be inserted into the punching through slot 55 smoothly. This not only requires the operator to stop the machine for manual adjustment, but may also cause the equipment to jam in severe cases, reducing the overall processing efficiency.

[0054] If the process sequence of folding, punching and then cutting is adopted, the problem of interference between the overall deformation of the U-shaped part and the punching seat 54 can be avoided. However, since the size of the punching through groove 55 and the contour through groove 34 is slightly larger than the shape of the U-shaped part, the U-shaped part is prone to misalignment and movement during cutting, which causes fluctuations in its position at the punching station, thereby affecting the accuracy of the hole position, or even causing the hole position to tilt, directly resulting in the scrapping of the profile.

[0055] See Figure 1 Therefore, based on the process of folding, cutting and punching, a connecting component 4 is installed on the top of the base 1. The connecting component 4 is located between the punching component 3 and the punching component 5. The connecting component 4 is used to obtain the U-shaped part punched to a fixed length and to transfer and transport the U-shaped part punched to a fixed length. During this process, the U-shaped part is adjusted as a whole so that the U-shaped part can be inserted into the punching through groove 55.

[0056] See Figures 7-9The specific structure of connector component 4 is as follows: The connecting assembly 4 includes a first wedge seat 41 mounted on the top of the base 1 and a second wedge seat 42 sliding on the side wall of the first wedge seat 41. Two transfer cylinders 43 are hinged to the top of the base 1. Both transfer cylinders 43 are hinged to the side wall of the second wedge seat 42. A rolling conveying mechanism 44, a guiding mechanism 47, and a guiding mechanism 49 are mounted on the top of the second wedge seat 42. Two V-shaped baffles 45 are symmetrically mounted on the top of the rolling conveying mechanism 44. When the U-shaped piece is cut to a fixed length by the punching assembly 3, the U-shaped piece will be driven to move downward at an angle. At this time, the U-shaped piece falls on the top of the rolling conveying mechanism 44, and the two V-shaped baffles 45 block the position of the U-shaped piece, causing the U-shaped piece to be between the two V-shaped baffles 45. Then the rolling conveying mechanism 44 drives the U-shaped piece to be conveyed towards the punching assembly 5.

[0057] See Figure 9 A roller pressing mechanism 46 is installed on the top of the second wedge-shaped seat 42. The roller pressing mechanism 46 extends to the top of the rolling conveying mechanism 44 and is located between the V-shaped baffle 45 and the guiding mechanism 47. The roller pressing mechanism 46 includes a roller pressing frame 461 installed on the top of the second wedge-shaped seat 42 and a lifting cylinder 462 vertically installed on the top of the roller pressing frame 461. A guide rail 463 is installed on one side of the roller pressing frame 461, and a slider 464 is slidably connected to the guide rail 463. The piston rod of the lifting cylinder 462 is connected to the slider 464. A pressure roller 465 is rotatably connected to the bottom. When the U-shaped part reaches below the roller pressing mechanism 46, the lifting cylinder 462 pushes the slider 464 to move down. The slider 464 slides on the side wall of the guide rail 463. The slider 464 drives the pressure roller 465 to move down and press it inside the U-shaped part. At this time, the U-shaped part is between the pressure roller 465 and the rolling conveying mechanism 44. When the rolling conveying mechanism 44 continues to convey forward, the pressure roller 465 works in sync, thereby allowing the U-shaped part to enter the interior of the guiding mechanism 47. The guiding mechanism 47 adjusts the U-shaped part as a whole.

[0058] While the U-shaped part is conveyed by the roller pressing mechanism 46 and the rolling conveying mechanism 44, the guiding mechanism 49 pushes and guides it, providing driving force for the adjustment of the U-shaped part.

[0059] The specific structure of the guiding mechanism 49 is as follows: The top of the second wedge seat 42 is equipped with a track 491, and an electric transfer trolley 492 slides on the side wall of the track 491. A bracket 493 is installed on the side wall of the electric transfer trolley 492. The bracket 493 extends to the top of the rolling conveyor mechanism 44 and is equipped with a guide cylinder 494. A guide plate 495 is connected to the bottom of the guide cylinder 494.

[0060] When the U-shaped piece lands on top of the rolling conveyor mechanism 44 and is conveyed forward synchronously, the position of the U-shaped piece is first blocked by two V-shaped baffles 45. Then the U-shaped piece is picked up by the pressure roller 465 and is conveyed between the pressure roller 465 and the rolling conveyor mechanism 44. At the same time, the guide cylinder 494 pushes the guide plate 495 downward to fit against the top of the rolling conveyor mechanism 44. Then the electric transfer trolley 492 moves in the direction of conveying the U-shaped piece. The guide plate 495 fits against the tail of the U-shaped piece and applies a pushing force to the tail of the U-shaped piece. With the help of the pressure roller 465 and the rolling conveyor mechanism 44, the U-shaped piece can enter the interior of the connecting mechanism 47.

[0061] See Figures 12-15 The specific structure of the guiding mechanism 47 is as follows: The engagement mechanism 47 includes an engagement block 471 mounted on the top of the second wedge seat 42 and an engagement groove 472 formed on one side of the engagement block 471. The engagement groove 472 is internally connected to a stop block 473. A guide portion 476 is formed on the side wall of the stop block 473. The size of the stop block 473 is smaller than the size of the engagement groove 472. An engagement through groove is formed between the stop block 473 and the engagement groove 472. The size of this engagement through groove is adapted to the U-shaped part.

[0062] An arc-shaped portion 475 is provided on the top of the side of the guide groove 472 facing the rolling conveyor mechanism 44. An extension block 474 is connected to the side of the guide block 471 away from the rolling conveyor mechanism 44. The U-shaped piece conveyed by the rolling conveyor mechanism 44 is fed into the interior of the guide groove 472.

[0063] If the U-shaped part undergoes a slight inward contraction, after entering the interior of the guide groove 472, it first comes into contact with the guide part 476. As the U-shaped part continues to be conveyed, the rolling conveyor mechanism 44 continues to convey it forward, cooperating with the pressure roller 465. This allows the U-shaped part to enter the guide mechanism 47 and gradually slide on the guide part 476 until it is adjusted to the same shape as the guide groove. During this process, the transfer cylinder 43 pushes the second wedge seat 42 to move. The second wedge seat 42 moves upward along the wedge surface of the first wedge seat 41, thereby adjusting the extension block 474 to the relative position with the punching seat 54. After passing through the guide groove 472, the U-shaped part continues to be supported by the extension block 474. By setting the extension block 474, the distance between the guide block 471 and the punching seat 54 is shortened. After passing through the extension block 474, the U-shaped part directly enters the interior of the punching groove 55 for continued conveying, thereby performing subsequent punching operations.

[0064] If only the top extension edge of the U-shaped part expands outward, the arc-shaped part 475 adjusts the outward expansion of the top extension edge of the U-shaped part during the process of the U-shaped part entering the guide groove 472, so that it shrinks inward.

[0065] In Example 3, when the U-shaped part exhibits slight outward expansion deformation, the distance between its two sides is greater than the matching size of the punching slot 55 at the punching station. When the end contacts the inlet of the punching slot 55, it will create a hard resistance, making it difficult to insert smoothly even with the aid of pushing force. This may cause further deformation of the workpiece or wear on the supporting structure, ultimately requiring manual intervention. See also... Figure 16 and Figure 17 The U-shaped part is affected by the punching component 3 and its position changes. When the U-shaped part falls to the top of the rolling conveyor 44, its position will be offset. This will not only prevent the roller pressing mechanism 46 from picking it up, but also affect the U-shaped part from entering the perforated through groove 55.

[0066] See Figure 8 To this end, a positioning mechanism 48 is also installed on the top of the second wedge seat 42. The positioning mechanism 48 is located below the rolling conveying mechanism 44 and below the roller pressing mechanism 46. When the U-shaped part moves to the bottom of the roller pressing mechanism 46, the positioning mechanism 48 clamps the U-shaped part, so that the position of the U-shaped part is adjusted to the bottom of the roller pressing mechanism 46, thereby facilitating the acquisition of the roller pressing mechanism 46. The positioning mechanism 48 can also adjust the outwardly expanding U-shaped part. The specific structure of the positioning mechanism 48 is as follows: See Figures 10-11 The positioning mechanism 48 includes two carrier rods 481 slidably connected to the top of the second wedge-shaped seat 42. A guide block 488 is connected to the bottom of each carrier rod 481. A limiting groove is formed at the top of the second wedge-shaped seat 42, and the guide block 488 is slidably connected inside the limiting groove. A guide groove 483 is connected to one side of each of the two carrier rods 481. A sliding column 484 is slidably connected inside the guide groove 483. A hinge rod 482 is hinged to the side wall of the end of each carrier rod 481 away from the guide groove 483. The end of the hinge rod 482 away from the corresponding carrier rod 481 is connected to the sliding column 484 on the other carrier rod 481. The two hinge rods 482 are hinged together. The first wedge seat 41 is equipped with a double-acting hydraulic cylinder 487. The two piston rods of the double-acting hydraulic cylinder 487 are connected to two carrier rods 481. By extending and retracting the piston rods of the double-acting hydraulic cylinder 487, the two carrier rods 481 can be driven to slide on the top of the second wedge seat 42 through the corresponding guide blocks 488. As the two carrier rods 481 move closer or further away from each other, the angle of the two hinge rods 482 changes. At the same time, the sliding column 484 slides inside the corresponding guide groove 483. The two hinge rods 482 cooperate to maintain the synchronicity of the movement of the two carrier rods 481 away from the end of the double-acting hydraulic cylinder 487.

[0067] Each carrier rod 481 has multiple columns 485 evenly spaced at its top. Each column 485 has a roller 486 rotating on its outer side wall. When the U-shaped part moves to the bottom of the roller pressing mechanism 46, the two carrier rods 481 move closer to each other, thereby driving the corresponding columns 485 and rollers 486 to move. This causes the multiple rollers 486 to clamp the side wall of the U-shaped part. During the process of conveying the U-shaped part in cooperation with the rolling conveying mechanism 44 and the pressure roller 465, the multiple rollers 486 rotate due to the movement of the U-shaped part. This allows the rollers 486 to alleviate the outward expansion of the side wall of the U-shaped part while cooperating with the movement of the U-shaped part.

[0068] Each support rod 481 has a swing plate 4802 hinged to its top and the end near the bidirectional cylinder 487. Multiple columns 485 corresponding to the support rod 481 are installed on the top of the swing plate 4802. A fixed seat 489 is installed on the side wall of the end of the support rod 481 away from the bidirectional cylinder 487. A telescopic cylinder 4801 is installed on the top of each fixed seat 489. The piston rod of the telescopic cylinder 4801 is hinged to the top of the corresponding swing plate 4802. The telescopic cylinder 4801 is used to push the corresponding swing plate 4802 to swing, that is, the distance between the two rollers 486 near the guide block 471 is shortened. Multiple rollers 486 on the top of the same swing plate 4802 are tilted in sequence. As the U-shaped part is conveyed, the closer the U-shaped part is to the guide block 471, the greater the pressure on its side wall.

[0069] An installation groove is provided in the middle of one end of the stop block 473 near the rolling conveyor mechanism 44. An industrial camera 6 is installed inside the installation groove. The industrial camera 6 is used to visually inspect the cross-sectional shape of the U-shaped part after it is cut.

[0070] Specifically, after the U-shaped part is squeezed and positioned by multiple rollers 486, the industrial camera 6 is used to detect the overall shape of the U-shaped part. If the side of the U-shaped part shrinks or the top extension edge shrinks or expands, the swing plate 4802 does not need to swing, and the U-shaped part can directly enter the interior of the guide groove 472 for adjustment.

[0071] If the side of the U-shaped part expands slightly, the telescopic cylinder 4801 corresponding to this side drives the corresponding swing plate 4802 to swing, causing the roller 486 to further squeeze the side of the U-shaped part, so that the expanded side continues to be squeezed inward. This setting can prevent the end of the U-shaped part from detaching from the roller 486 and expanding again before reaching the inside of the guide groove 472.

[0072] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
