Description

Technical Field

[0001] This invention belongs to the field of bolt cutting and processing technology, specifically a bolt cutting equipment for bolt production. Background Technology

[0002] Bolts are a common type of fastener that connects two or more components by mating with a nut or by screwing directly into a threaded hole. Bolts are typically manufactured by processing bar stock through steps such as cutting, upsetting, and turning. When cutting the bar stock, the cutting process is usually carried out according to the type of bolt being produced.

[0003] A patent with publication number CN119368811B discloses a cutting device for bolt production. This device uses two support plates to support the right side of the bar cutting section. Before the bar moves to the corresponding position on the cutting device, the support plates are located on the lower right side of the bar. Therefore, when the bar is transported to the corresponding position on the cutting device, the two support plates do not obstruct the end of the bar, allowing the cutting section to move to the corresponding position on the cutting device, increasing the cutting efficiency. A positioning plate and a triangular plate are used to position the right end of the bar, and the distance between the positioning plate and the triangular plate and the cutting device is adjustable. When the two support plates move to the left to support the right side of the bar cutting section, the positioning plate and the triangular plate can abut against the right end of the bar. This allows for precise adjustment of the bar cutting position based on the distance between the positioning plate and the triangular plate and the cutting device, increasing the cutting accuracy of the bar.

[0004] The above-mentioned solution still has some problems in practical application. Usually, the bar stock is placed on the cutting table, and the bar stock is pushed to adjust the cutting position. Then the cutting equipment is driven to cut the bar stock. After the cutting is completed, the cut bolt blanks are collected, and then the bar stock is pushed again to adjust the cutting position for cutting. However, the existing cutting method is basically a point-to-point vertical or horizontal movement cutting. Not only is the cutting resistance high and the cutting efficiency low, but the cutting blade is also prone to overload damage. Furthermore, the cut edge of the bolt blank needs to be ground separately using grinding equipment, which greatly affects the bolt production efficiency.

[0005] Therefore, the present invention provides a cutting device for bolt production. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0012] Preferably, four T-shaped support columns are installed on the upper end of the base, and the four T-shaped support columns are arranged in pairs and symmetrically. Each T-shaped support column is slidably connected to a T-shaped mounting block. A tension spring is fixedly connected to the lower end of the T-shaped mounting block, and one end of the tension spring is fixedly connected to the base. A bar stock limiting component is installed between the T-shaped mounting blocks to press the bar stock by pulling the bar stock limiting component, which can improve the stability of bar stock conveying.

[0013] Preferably, the bar stock limiting assembly includes a support frame installed between the T-shaped mounting blocks. The inner cavity of the support frame is rotatably connected to multiple rotating columns, and each rotating column has a first sliding groove inside. The inner cavity of the first sliding groove is slidably connected to two limiting slides, and the surfaces of the limiting slides are arranged in a semi-circular arc shape to clamp bars of different diameters and limit the position of the bars.

[0014] Preferably, two fixed discs are installed on the outside of the rotating column, and a second spring is installed at one end of the limiting slide, with one end of the second spring abutting against the support frame.

[0015] Preferably, a cutting length adjustment component is installed on one side of the upper end face of the base, and the cutting length adjustment component includes two grooves opened on one side of the upper end face of the base. A threaded rod is rotatably connected to the inner cavity of the groove, and a U-shaped sliding frame is threadedly connected to the outer side of the threaded rod. A scale groove is opened on one side of the upper end face of the base located in the groove, which is used to drive the position of the U-shaped sliding frame in the inner cavity of the groove, and the U-shaped sliding frame can be used to block the conveying of the bar material.

[0016] Preferably, the grinding disc has a second groove at one end, a slider is slidably connected to the inner cavity of the second groove, and a stop block is fixed to one end of the slider, with one end of the stop block being semi-circular.

[0017] Preferably, a sliding column is fixedly connected to the inner cavity of the second chute, the slider is slidably connected to the sliding column, a first spring is fixedly connected to one end of the slider, one end of the first spring is fixedly connected to the inner wall of the second chute, and four limiting pulleys are rotatably connected to the inner wall of the recycling channel, and the four limiting pulleys are arranged in pairs and symmetrically to assist the rotation of the gear ring.

[0018] Preferably, a recycling guide assembly is provided on one side of the upper end face of the base, and the recycling guide assembly includes a flip-out opening on one side of the upper end face of the base. Two rotating grooves are provided on the inner wall of the flip-out opening. A flip plate is rotatably connected to the inner cavity of the flip-out opening. A rotating disk is fixedly connected to the flip plate outside the inner cavity of the rotating groove. A torsion spring is fixedly connected to one side of the rotating disk, and one end of the torsion spring is fixedly connected to the inner wall of the rotating groove.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The bolt production cutting equipment of the present invention conveys the bar stock into the inner cavity of the gear ring through a bar stock conveying assembly. Then, a servo push rod drives a disc blade to approach the bar stock, and a motor drives the disc blade to cut the bar stock. Simultaneously, the gear ring rotates around the bar stock in a circular motion for cutting. When the gear ring moves the grinding disc to the cutting edge of the bar stock, the servo push rod drives the grinding disc to insert it into the cutting edge of the bar stock. At the same time, as the gear ring rotates, the grinding disc rotates synchronously to grind the cutting edge of the bar stock. At the same time, a first spring lifts the slider, and the slider drives the abutment block to slide outside the slide column to grind one end of the bar stock. This avoids the trouble of separately grinding the cutting edge of the bolt blank when turning the bolt blank into a bolt later, and improves the efficiency of bolt blank cutting.

[0021] 2. The bolt production cutting equipment of the present invention utilizes a tension spring to pull a T-shaped mounting block, causing a support frame to move downwards and a rotating column to move downwards. The rotating column then presses down on the bar stock to ensure stability during transport. While pressing down on the bar stock, a second spring is used to spring up limiting slides that move closer to each other, thereby using the two limiting slides to further clamp and limit the bar stock, improving the stability of the bar stock during transport and cutting, and preventing the bar stock from shifting during transport and cutting, which would affect the cutting accuracy.

[0022] 3. The bolt production cutting equipment of the present invention utilizes the weight of the bolt blank to drive the flipping plate to flip, and the flipping plate drives the rotating disk to flip, which in turn causes the rotating disk to twist the torsion spring and flip downward, thereby guiding the bolt blank along the inclined flipping plate to slide out of the base for collection. Then, the torsion spring twists the rotating disk to rotate, and the rotating disk drives the flipping plate to rotate and reset, waiting to receive the next bolt blank, thereby realizing the cyclic cutting and recycling operation of bolt blanks, further improving bolt production efficiency.

[0040] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0041] Example 1: As Figures 1 to 8 As shown in the embodiment of the present invention, a bolt production cutting device includes a base 1, a conveying roller 2 is provided on one side of the upper end face of the base 1, a bar material conveying assembly 3 is installed in the inner cavity of the conveying roller 2 for conveying bar material 10 according to the length of the bolt to be produced, and a recycling groove 4 is provided on one side of the upper end face of the base 1, and a cutting and grinding assembly 5 is provided in the inner cavity of the recycling groove 4.

[0042] The cutting and grinding assembly 5 includes four gears 52 installed on the inner wall of the recycling channel 4. The four gears 52 are arranged in pairs and symmetrically. The gears 52 mesh with two gear rings 51, and the two gear rings 51 are connected in series. Three servo push rods 55 are installed between the two gear rings 51. A disc blade 54 is installed on the piston rod end of one of the servo push rods 55, and grinding discs 57 are fixed to the piston rod ends of the other two servo push rods 55 for grinding the cut of the bar stock 10.

[0043] The bar stock conveying assembly 3 includes a plurality of conveying rollers 31 rotatably connected in the inner cavity of the conveying roller track 2. The conveying rollers 31 are arranged in a semi-circular shape with concave inner and convex outer sides, and rubber anti-slip teeth are arranged in a ring on the outside of the conveying rollers 31, which enables the bar stock 10 to be conveyed in the middle of the conveying rollers 31.

[0044] Specifically, in existing technologies, the bar stock is usually placed on a cutting table, and the bar stock is pushed to adjust the cutting position. Then, the cutting equipment is driven to cut the bar stock. After the cutting is completed, the cut bolt blanks are collected, and the bar stock is pushed again to adjust the cutting position for further cutting. However, the existing cutting method is basically a point-to-point vertical or horizontal movement cutting, which not only has high resistance and low cutting efficiency, but also makes the cutting blades easy to damage. Furthermore, the cut edges of the bolt blanks need to be ground separately using grinding equipment, which greatly affects the bolt production efficiency.

[0045] This invention places the bar stock 10 within the conveyor roller 2 and simultaneously drives the conveyor roller 31 to rotate. The conveyor roller 31 is a semi-circular structure with an inward concave and outward convex shape, and its outer surface is annularly equipped with rubber anti-slip teeth. This stable conveying of the bar stock 10 towards the cutting and grinding assembly 5 ensures that the bar stock 10 remains in the center of the conveyor roller 31, preventing lateral movement of the bar stock 10 from affecting cutting accuracy. After the bar stock 10 is positioned correctly, the drive gear 52 rotates, meshing with the transmission gear ring 51. Simultaneously, the gear ring 51 drives the servo push rod 55 to rotate synchronously. During the rotation of the gear ring 51, the servo push rod 55 is activated to drive the disc blade 54 closer to the bar stock 10, and the disc blade 54 is activated to run. This, in turn, drives the servo push rod 55 to rotate synchronously. 5. During the rotation process, the disc blade 54 can cut around the bar stock 10 in a ring shape. Compared with the existing method of cutting in a straight line from top to bottom or bottom to top using a disc blade, this method not only reduces resistance but also ensures the flatness of the cut. Then, the servo push rod 55 drives the grinding disc 57 to move and insert it into the cut of the bar stock 10. During the rotation of the gear ring 51, the servo push rod 55 is driven to rotate, and the servo push rod 55 drives the grinding disc 57 to rotate synchronously. Thus, the grinding disc 57 can be used to grind the cut of the bar stock 10. The disc blade 54 cuts around the bar stock 10 in a ring shape, which can reduce the unevenness of the cut of the bar stock 10. The grinding disc 57 can grind the cut more quickly, which is beneficial to the quality of the bolt processing and manufacturing in the later stage, thereby solving the above problems.

[0046] like Figure 1 , Figure 2 and Figure 5 As shown, a transmission groove 32 is provided in one end of the base 1. A rotating shaft 35 is rotatably connected to the inner cavity of the transmission groove 32. Multiple driven bevel gears 34 are fixedly connected to the outside of the rotating shaft 35. The multiple driven bevel gears 34 are meshed with a first bevel gear 33. The first bevel gear 33 is fixedly connected to the conveying roller 31.

[0047] like Figure 1 , Figure 2 and Figure 5 As shown, a servo motor 11 is installed at one end of the base 1. The output shaft end of the servo motor 11 is located in the inner cavity of the transmission groove 32 and a transmission bevel gear 36 is fixedly connected. The transmission bevel gear 36 is meshed with the driven bevel gear 34 and is used to drive the conveying roller 31 to transport the bar material 10.

[0048] Specifically, when conveying the bar stock 10 to produce bolt blanks, the servo motor 11 is started to drive the transmission bevel gear 36 to rotate, and the transmission bevel gear 36 meshes with the driven bevel gear 34 to rotate, which in turn drives the rotating shaft 35 to rotate. During the rotation of the rotating shaft 35, the driven bevel gear 34 will rotate synchronously. At the same time, the driven bevel gear 34 meshes with the first bevel gear 33 to rotate, which in turn drives the conveying roller 31 to rotate. Thus, the bar stock 10 can be conveyed and moved according to the cutting requirements, improving the automation level of the cutting equipment and increasing the processing efficiency of the bolt blanks.

[0049] like Figures 1 to 2 As shown, four T-shaped support columns 12 are installed on the upper end of the base 1, and the four T-shaped support columns 12 are arranged in pairs and symmetrically. Each T-shaped support column 12 is slidably connected to a T-shaped mounting block 13. A tension spring 14 is fixedly connected to the lower end of the T-shaped mounting block 13. One end of the tension spring 14 is fixedly connected to the base 1. A bar stock limiting component 9 is installed between the T-shaped mounting blocks 13. The bar stock limiting component 9 is used to pull the bar stock limiting component 9 to press the bar stock 10, which can improve the stability of the bar stock 10 conveying.

[0050] Specifically, when conveying and cutting the bar stock 10, the tension spring 14 pulls the T-shaped mounting block 13 to slide downwards outside the T-shaped support column 12, causing the T-shaped mounting block 13 to drive the bar stock limiting component 9 to move downwards synchronously. The bar stock limiting component 9 then presses and limits the bar stock 10, while simultaneously conveying the bar stock 10 with the conveying roller 31. Furthermore, the bar stock limiting component 9, in conjunction with the conveying roller 31, can clamp the bar stock 10. The limiting effect of the bar stock limiting component 9 ensures that the bar stock 10 will not move or shake during the cutting process, improving the cutting accuracy of the bar stock 10. This solves the problem of existing bolt production cutting equipment, which typically uses a clamping component to hold and fix the bar stock before operating the cutting component to cut it. After cutting, the clamping component needs to be loosened to adjust the position of the conveyed bar stock before cutting the bolt stock again, which is not only cumbersome but also affects the processing efficiency of bolt stock.

[0051] like Figure 1 , Figure 3 and Figure 4As shown, the bar stock limiting assembly 9 includes a support frame 91 installed between T-shaped mounting blocks 13. Multiple rotating columns 92 are rotatably connected to the inner cavity of the support frame 91, and each rotating column 92 has a first sliding groove 93 inside. Two limiting slides 94 are slidably connected to the inner cavity of the first sliding groove 93, and the surfaces of the limiting slides 94 that are close to each other are arranged in a semi-circular arc shape, which is used to clamp bars 10 of different diameters and limit the position of the bars 10.

[0052] like Figure 1 , Figure 3 and Figure 4 As shown, two fixed discs 96 are installed on the outside of the rotating column 92, and a second spring 95 is installed at one end of the limiting slide 94, and one end of the second spring 95 abuts against the support frame 91.

[0053] Specifically, during the conveying and cutting of the bar stock 10, the tension spring 14 pulls the T-shaped mounting block 13 to move the support frame 91 downwards, which in turn moves the rotating column 92 downwards. The rotating column 92 then presses down on the bar stock 10, ensuring its stability during conveying. Furthermore, while pressing down on the bar stock 10, the second spring 95 springs up the limiting slides 94, which move closer together. The surfaces of the limiting slides 94 are semi-circular, allowing the two limiting slides 94 to further clamp and limit the bar stock 10 as the support frame 91 moves the rotating column 92 downwards. This improves the stability of the bar stock 10 during conveying and cutting, preventing deviations that could affect cutting accuracy. This solves the problem that existing bolt production cutting equipment cannot process bolt blanks of different sizes due to the inconvenience of clamping and limiting bar stock of varying thicknesses.

[0054] Example 2: Figure 2 , Figure 5 and Figure 8 As shown, a cutting length adjustment component 6 is installed on one side of the upper end face of the base 1, and the cutting length adjustment component 6 includes two grooves 61 opened on one side of the upper end face of the base 1. A threaded rod 62 is rotatably connected to the inner cavity of the groove 61, and a U-shaped sliding frame 63 is threadedly connected to the outer side of the threaded rod 62. A scale groove 8 is opened on one side of the upper end face of the base 1 located in the groove 61, which is used to drive the position of the U-shaped sliding frame 63 in the inner cavity of the groove 61, and can use the U-shaped sliding frame 63 to block the conveying of the bar stock 10.

[0055] Specifically, when cutting the bar stock 10, the threaded rod 62 is driven to rotate, causing the threaded rod 62 to drive the U-shaped sliding frame 63 to slide within the groove 61. Simultaneously, the graduated groove 8 passes through the U-shaped sliding frame 63, and the bar stock 10 is fed by the bar stock conveying assembly 3, causing the bar stock 10 to abut against the U-shaped sliding frame 63. The length of the bolt blank is at the point where the cutting and grinding assembly 5 reaches the U-shaped sliding frame 63. Therefore, when cutting and processing bolt blanks in the same batch, there is no need to adjust the position of the U-shaped sliding frame 63; instead, the cutting and grinding assembly... After component 5 cuts the bar stock 10, the bar stock 10 is automatically conveyed by the bar stock conveying component 3, so that the bar stock 10 abuts against the U-shaped sliding frame 63, and the cutting and grinding component 5 is driven to cut the bar stock 10. This realizes the cyclic cutting processing of bolt blanks, improves the production efficiency of bolts, and solves the problem that when the existing bolt production cutting equipment cuts the bar stock to process bolt blanks, it is necessary to measure the cutting position of the bar stock after each cutting to ensure that the length of the bolt blank meets the standard. This is not only cumbersome to operate, but also affects the production efficiency of bolt blanks.

[0056] like Figure 1 , Figure 6 and Figure 7 As shown, a second groove 56 is provided at one end of the grinding disc 57. A slider 59 is slidably connected to the inner cavity of the second groove 56. A stop block 510 is fixedly connected to one end of the slider 59, and one end of the stop block 510 is set in a semi-circular arc shape.

[0057] like Figure 1 , Figure 6 and Figure 7 As shown, a sliding column 511 is fixedly connected to the inner cavity of the second slide groove 56, and a slider 59 is slidably connected to the sliding column 511. A first spring 58 is fixedly connected to one end of the slider 59, and one end of the first spring 58 is fixedly connected to the inner wall of the second slide groove 56. Four limiting pulleys 53 are rotatably connected to the inner wall of the recycling channel 4, and the four limiting pulleys 53 are arranged in pairs and symmetrically to assist the rotation of the gear ring 51.

[0058] Specifically, when cutting the bar stock 10, the bar stock 10 is fed into the inner cavity of the gear ring 51 by the bar stock conveying assembly 3. Then, the disc blade 54 is driven by the servo push rod 55 to approach the bar stock 10, and the disc blade 54 is driven by the motor to cut the bar stock 10. At the same time, the gear ring 51 rotates around the bar stock 10 in a circular motion to cut. When the gear ring 51 drives the grinding disc 57 to move to the cutting edge of the bar stock 10, the grinding disc 57 is driven by the servo push rod 55, and the grinding disc 57 is cut by the servo push rod 55. The grinding disc 57 is inserted into the cut of the bar stock 10. At the same time, as the gear ring 51 rotates, the grinding disc 57 rotates synchronously to grind the cut of the bar stock 10. Meanwhile, the first spring 58 lifts the slider 59, and the slider 59 drives the abutment 510 to slide outside the slide post 511 to grind one end of the bar stock 10. This avoids the trouble of grinding the cut of the bolt blank separately when turning the bolt blank later, and improves the efficiency of bolt blank cutting.

[0059] like Figure 1 , Figure 2 and Figure 8 As shown, a recycling guide assembly 7 is provided on one side of the upper end face of the base 1, and the recycling guide assembly 7 includes a flip-out opening 71 opened on one side of the upper end face of the base 1. Two rotating grooves 72 are opened on the inner wall of the flip-out opening 71. A flip plate 73 is rotatably connected to the inner cavity of the flip-out opening 71. A rotating disk 74 is fixedly connected to the outside of the inner cavity of the rotating groove 72 on the flip plate 73. A torsion spring 75 is fixedly connected to one side of the rotating disk 74, and one end of the torsion spring 75 is fixedly connected to the inner wall of the rotating groove 72.

[0060] Specifically, after the bolt blank is cut from the bar stock 10, the weight of the bolt blank drives the flipping plate 73 to flip, and the flipping plate 73 drives the rotating disk 74 to flip. This causes the rotating disk 74 to twist the torsion spring 75 and flip downwards, so that the bolt blank is guided to slide out of the base 1 along the inclined flipping plate 73 for collection. Then, the torsion spring 75 twists the rotating disk 74 to rotate, and the rotating disk 74 drives the flipping plate 73 to rotate and reset, thus waiting to receive the next bolt blank. This solves the problem that in the existing bolt production cutting equipment, after the bar stock is cut, the operator needs to collect the cut bolt blank before pushing the bar stock for the next bolt blank cutting process, which leads to cumbersome operation and affects the cutting efficiency of bolt blanks.

[0061] The working principle is as follows: The bar stock 10 is placed inside the conveyor roller 2, and the conveyor roller 31 is driven to rotate. The conveyor roller 31 is a semi-circular shape with an inward and outward convex design, and its outer surface is equipped with annular rubber anti-slip teeth. This stabilizes the bar stock 10 as it moves towards the cutting and grinding assembly 5. The inward and outward convex design of the conveyor roller 31 ensures that the bar stock 10 remains in the center of the conveyor roller 31, preventing lateral movement of the bar stock 10 from affecting cutting accuracy. After the bar stock 10 is positioned correctly, the drive gear 52 rotates, meshing with the transmission gear ring 51. Simultaneously, the gear ring 51 drives the servo push rod 55 to rotate synchronously. During the rotation of the gear ring 51, the servo push rod 55 drives the disc blade 54 closer to the bar stock 10, and the disc blade 54 begins to move. This movement, driven by the gear ring 51, further enhances the cutting accuracy. During the rotation of the servo push rod 55, the disc blade 54 can cut around the bar stock 10 in a ring shape. Compared with the existing method of cutting in a straight line from top to bottom or bottom to top using the disc blade, this method not only reduces resistance but also ensures the flatness of the cut. Then, the servo push rod 55 drives the grinding disc 57 to move and insert the grinding disc 57 into the cut of the bar stock 10. During the rotation of the gear ring 51, the servo push rod 55 is driven to rotate, and the servo push rod 55 drives the grinding disc 57 to rotate synchronously. Thus, the grinding disc 57 can be used to grind the cut of the bar stock 10. The disc blade 54 cuts around the bar stock 10 in a ring shape, which can reduce the unevenness of the cut of the bar stock 10. Then, the grinding disc 57 can grind the cut more quickly, so as to improve the quality of the bolt processing and manufacturing in the later stage.

[0062] When conveying and cutting the bar stock 10, the tension spring 14 pulls the T-shaped mounting block 13 to move the support frame 91 downward, and the support frame 91 moves the rotating column 92 downward. The rotating column 92 then presses down on the bar stock 10 to ensure the stability of the bar stock 10 during conveying. When pressing down on the bar stock 10, the second spring 95 pops up the limiting slides 94 to move closer to each other. The surfaces of the limiting slides 94 that move closer to each other are set in a semi-circular arc shape. As the support frame 91 moves the rotating column 92 downward, the two limiting slides 94 further clamp and limit the bar stock 10 to improve the stability of the bar stock 10 during the conveying and cutting process and prevent the bar stock 10 from deviating during the conveying and cutting process, which would affect the cutting accuracy.

[0063] When cutting the bar stock 10, the threaded rod 62 is driven to rotate, and the threaded rod 62 drives the U-shaped sliding frame 63 to slide in the inner cavity of the groove 61. At the same time, the scale groove 8 passes through the moving position of the U-shaped sliding frame 63. Then, the bar stock 10 is fed by the bar stock conveying assembly 3, and then the bar stock 10 abuts against the U-shaped sliding frame 63. The length of the bolt blank is at the position of the cutting and grinding assembly 5 at the U-shaped sliding frame 63. Therefore, when cutting and processing bolt blanks in the same batch, there is no need to adjust the position of the U-shaped sliding frame 63. After the bar stock 10 is cut by the cutting and grinding assembly 5, the bar stock 10 is automatically conveyed by the bar stock conveying assembly 3, and after the bar stock 10 abuts against the U-shaped sliding frame 63, the cutting and grinding assembly 5 is driven to cut the bar stock 10, thereby realizing the cyclic cutting and processing of bolt blanks and improving the production efficiency of bolts.

[0064] After the bolt blank is cut and processed from the bar stock 10, the weight of the bolt blank drives the flipping plate 73 to flip, and the flipping plate 73 drives the rotating disk 74 to flip. This causes the rotating disk 74 to twist the torsion spring 75 and flip downward, so that the bolt blank is guided to slide out of the base 1 along the inclined flipping plate 73 for collection. Then, the torsion spring 75 twists the rotating disk 74 to rotate, and the rotating disk 74 drives the flipping plate 73 to rotate and reset, so as to wait for the next bolt blank to be received, thus realizing the cyclic cutting and processing operation of the bolt blank.

[0065] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
