Description

Technical Field

[0001] The invention relates to the technical field of rust removal, in particular to a steel strand wire drawing rust removal device. Background Art

[0002] Steel wire production uses hot-rolled wire as raw material and is processed through four major processes: surface treatment, heat treatment, drawing, and plating (coating, cladding). Depending on the different needs of the finished steel wire, auxiliary processes such as peeling and polishing may be required. The main purpose of surface treatment is to remove oxide scale and apply lubricating carrier. The presence of oxide scale on the surface of the wire will cause surface defects of the steel wire and premature damage to the die, and may even block the die hole and cause drawing fracture. Therefore, removing the oxide scale on the surface of the wire before drawing is a very important process.

[0003] Hot-rolled carbon steel wire is the main raw material for steel wire drawing. Its surface oxide scale is mainly composed of iron oxide and ferroferric oxide. The existing removal methods are mostly repeated bending methods. Because the oxide scale is brittle and has no ductility, it is easy to crack under mechanical action and thus detach from the surface of the steel wire. By setting multiple groups of bending rollers at different positions on the steel wire conveying line, the steel wire is continuously bent in different directions, causing repeated extension and compression on the surface of the steel wire, which promotes the loosening and peeling of the surface oxide scale. However, this method can only remove about 80% of the oxide scale on the surface of the steel wire at most. There will still be some stubborn rust on the surface of the steel wire, which requires physical grinding to remove the surface rust. However, the existing grinding equipment cannot accurately locate the grinding point according to the position of the rust on the surface of the steel wire, and the rust removal efficiency is not high. Summary of the invention

[0004] The object of the present invention is to provide a steel strand wire drawing and rust removal device to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: the rust removal device includes a frame, a guide mechanism, a control system, a detection mechanism and a grinding mechanism, the guide mechanism is rotatably connected to the frame, the guide mechanism is used to guide the workpiece, the control system is tightly connected to the frame, the control system is used to control the actions of the detection mechanism and the grinding mechanism, the detection mechanism and the grinding mechanism are arranged in sequence along the conveying direction of the workpiece, the detection mechanism is tightly connected to the frame, the detection mechanism is used to detect the position of rust on the surface of the workpiece, the grinding mechanism is tightly connected to the frame, and the grinding mechanism is used to remove rust on the surface of the workpiece.

[0006] The workpiece processed by the present invention is a wire from which most of the oxide layer has been removed by repeated bending. The stubborn rust remaining on the surface of the wire is polished, and the workpiece is sent into the rust removal device for treatment through a corresponding traction mechanism. The traction mechanism is a prior art and will not be described in detail here. The frame is used to provide a stable working environment for each mechanism. The workpiece entering the rust removal device is first guided by the guide mechanism so that the movement path of the workpiece tends to be stable, and then passes through the detection mechanism and the polishing mechanism in turn. The detection mechanism can detect the position of the rust on the surface of the workpiece, and then the control system controls the polishing mechanism to accurately polish the rust, thereby improving the efficiency of rust treatment.

[0007] Furthermore, the detection mechanism includes a fixed ring, a guide ring and a detection assembly. The fixed ring is tightly connected to the frame, the guide ring is tightly connected to the fixed ring, the guide ring is located in the inner ring of the fixed ring, the detection assembly is slidably connected to the guide ring, and the detection assembly is used to detect rust on the surface of the workpiece.

[0008] The fixing ring is fixed on the frame to provide an installation basis for the detection mechanism, and the guide ring can guide the detection component so that the detection component is close to the surface of the workpiece, thereby facilitating the detection component to detect the rust position on the surface of the workpiece.

[0009] Furthermore, the detection component includes a detection block and a support spring. A guide groove is provided on the guide ring. The detection block is slidably connected to the guide groove. One end of the support spring is firmly connected to the detection block. The other end of the support spring is firmly connected to the inner wall of the guide groove. The support spring is located on the side of the guide groove close to the grinding mechanism. The detection block is arc-shaped. Several detection blocks are arranged along the inner ring of the guide ring. Several detection blocks form a complete detection ring. The inner diameter of the detection ring is the same as the outer diameter of the workpiece. The contact surface between the detection ring and the workpiece is smooth.

[0010] Because there are several detection blocks arranged along the inner ring of the guide ring, and they form a complete detection ring with the same outer diameter as the workpiece, the inner ring of the detection ring will abut the surface of the workpiece, and there are gaps between the detection blocks, so they can make relative movements. The workpiece passes through the rust removal device at a certain speed, and the rusted position on the workpiece surface is relatively rough, while the position without rust is relatively smooth. That is, when the rusted position passes through the detection block at the corresponding position, the friction force on the detection block is greater than that without rust, which will drive the detection block at this position to slide along the guide groove, and the supporting spring is compressed. The sliding direction is the same as the movement direction of the workpiece. By detecting which area the detection block is located, it can be determined. If the rust on the workpiece moves, the position of the rust on the workpiece can be determined; in addition, if the rust on the workpiece surface is longer, the friction will continue to act on the detection block for a period of time, causing the detection block to maintain an offset state for a certain period of time. By detecting the offset time of the detection block in this area, the length of the rust on the workpiece surface can be determined. The longer the offset time of the detection block, the longer the rust on the workpiece surface. Moreover, if the rust on the workpiece is rougher, the friction on the detection block is greater, and the distance the detection block slides along the guide groove is longer. The roughness of the rust can be determined by detecting the moving distance of the detection block. The longer the offset distance of the detection block, the greater the roughness of the rust.

[0011] Furthermore, the detection assembly also includes a first telescopic rod, a connecting block, a second telescopic rod, a slider, an iron core, a repelling magnet and a pressure strain gauge, one end of the first telescopic rod is hinged to the detection block, the other end of the first telescopic rod is tightly connected to the connecting block, one end of the second telescopic rod is tightly connected to the connecting block, the other end of the second telescopic rod is hinged to the slider, a support frame is provided on the guide ring, the connecting block is rotatably connected to the support frame, a slide groove and a detection cavity are provided on the fixed ring, the detection cavity is located at an end of the slide groove away from the grinding mechanism, the slider is slidably connected to the slide groove, the iron core is tightly connected to the slider, the iron core faces the detection cavity, the pressure strain gauge is tightly connected to the inner wall of the detection cavity, the pressure strain gauge is electrically connected to the control system, the repelling magnet abuts against the detection surface of the pressure strain gauge, and a coil is wound around one end of the slide groove close to the detection cavity, and the coil is externally connected to a power supply;

[0012] During detection: the iron core is inserted into the coil to form an electromagnet, and the facing surfaces of the electromagnet and the repelling magnet are the same magnetic poles.

[0013] When the detection block deviates along the guide groove under the action of rust on the surface of the workpiece, it will drive the first telescopic rod hinged to the detection block to deflect, and then drive the connecting block to rotate around the support frame, so that the second telescopic rod fixed to the connecting block deflects to the other side, and then drives the slider hinged to the second telescopic rod to move along the slide groove toward the detection cavity, so that the iron core is inserted into the coil to form an electromagnet. Because the facing ends of the electromagnet and the repelling magnet are the same magnetic poles, according to the principle of like poles repel each other, the electromagnet will exert a thrust on the repelling magnet, causing the pressure strain gauge to be compressed, the current cross-section of the pressure strain gauge will decrease, and the resistance value will decrease. Increase; and, if the rust on the surface of the workpiece is rougher, the longer the offset distance of the detection block is, the longer the offset distance of the second telescopic rod is, the longer the distance the iron core is inserted into the coil, the greater the thrust of the electromagnet on the repelling magnet, the greater the resistance of the pressure strain gauge, that is, the greater the roughness of the rust on the surface of the workpiece, the greater the resistance of the pressure strain gauge; in addition, if the rust on the surface of the workpiece is longer, the offset time of the detection block is longer, the longer the time the iron core is inserted into the coil, and the longer the resistance of the pressure strain gauge is maintained, that is, the longer the rust on the surface of the workpiece, the longer the resistance of the pressure strain gauge is maintained.

[0014] Furthermore, the length of the second telescopic rod is greater than the length of the first telescopic rod.

[0015] The detection block is offset by a small distance under the action of friction and is difficult to detect. The first telescopic rod, the connecting block and the second telescopic rod form a lever structure with the connecting block as the rotation center, which amplifies the offset distance of the detection block, thereby facilitating subsequent detection.

[0016] Furthermore, the grinding mechanism includes a connecting ring, an electric push rod and a grinding block. The connecting ring is tightly connected to the frame, the electric push rod is tightly connected to the connecting ring, the output end of the electric push rod is transmission connected to the grinding block, and the grinding blocks are arranged in several groups along the inner ring of the connecting ring. Several grinding blocks form a complete grinding ring, and the positions of the several grinding blocks correspond one by one to the positions of the several detection blocks.

[0017] The connecting ring is fixed on the frame to provide support for the grinding mechanism. The diameter of the grinding ring composed of several grinding blocks is larger than the diameter of the workpiece. Under normal conditions, the grinding blocks do not contact the surface of the workpiece. When the detection mechanism detects that there is rust in a certain area on the surface of the workpiece, the position of the detection block at the corresponding position will be offset. The control system starts the electric push rod at the corresponding position, so that the grinding surface of the grinding block at the corresponding position fits the surface of the workpiece, and the rust on the surface of the workpiece is polished, that is, the automatic positioning of the rust position is realized, thereby improving the grinding efficiency; and the rougher the rust on the surface of the workpiece, the faster the control system will move. The greater the resistance of the pressure strain gauge detected by the control system, the greater the grinding pressure applied by the electric push rod, that is, the automatic adjustment of the grinding pressure according to the roughness of the workpiece surface is realized, thereby improving the grinding effect; in addition, the longer the rust on the workpiece surface, the longer the offset time of the detection block, the longer the time the iron core is inserted into the coil, the longer the resistance of the pressure strain gauge is maintained, and the time that the electric push rod maintains the grinding state under the control of the control system is increased accordingly, that is, the automatic control of the grinding time according to the length of the rust on the workpiece surface is realized, thereby reducing the wear of the grinding block.

[0018] Furthermore, the grinding block is in an arc shape and is made of a flexible material.

[0019] The arc-shaped flexible grinding block can fit the surface of the workpiece to ensure the grinding effect.

[0020] Furthermore, the guide mechanism is arranged at the feed port and the discharge port of the frame, and the guide mechanism includes a guide wheel and a rotating shaft, the guide wheel is tightly connected to the rotating shaft, and the rotating shaft is rotatably connected to the frame.

[0021] The two sets of guide mechanisms are respectively arranged at the feed port and the discharge port of the frame. The workpiece is guided by the guide wheels arranged up and down, so that the workpiece passes through the detection mechanism and the grinding mechanism in a stable state, and the rotating shaft serves as the rotation basis of the guide wheels.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The position with rust on the workpiece surface is relatively rough, while the position without rust is relatively smooth. That is, when the position with rust passes through the detection block at the corresponding position, the friction force on the detection block is greater than that without rust, which will drive the detection block at this position to slide along the guide groove, and the support spring is compressed. The sliding direction is the same as the movement direction of the workpiece. By detecting which area of ​​the detection block has moved, the position of the rust on the workpiece can be determined, and the automatic positioning of the rust position is realized;

[0024] 2. When the detection mechanism detects that there is rust in a certain area on the surface of the workpiece, the position of the detection block at the corresponding position will be offset, and the electric push rod at the corresponding position will be started by the control system, so that the grinding surface of the grinding block at the corresponding position is attached to the surface of the workpiece, and the rust on the surface of the workpiece is polished, that is, the automatic positioning of the rust position is realized, thereby improving the polishing efficiency; and the rougher the rust on the surface of the workpiece, the greater the resistance value of the pressure strain gauge detected by the control system, and the grinding pressure applied by the electric push rod will increase accordingly, that is, the automatic adjustment of the grinding pressure according to the roughness of the workpiece surface is realized, thereby improving the polishing effect; in addition, the longer the rust on the surface of the workpiece, the longer the offset time of the detection block, the longer the time the iron core is inserted into the coil, the longer the resistance value of the pressure strain gauge is maintained, and the time that the electric push rod maintains the grinding state under the control of the control system is correspondingly increased, that is, the automatic control of the grinding time according to the length of the rust on the surface of the workpiece is realized, thereby reducing the wear of the grinding block.

[0036] Example: Figure 1-Figure 9 As shown, the present invention provides a technical solution for a steel strand wire drawing and rust removal device, the rust removal device includes a frame 1, a guide mechanism 2, a control system 3, a detection mechanism 4 and a grinding mechanism 5, the guide mechanism 2 is rotatably connected to the frame 1, the guide mechanism 2 is used to guide the workpiece, the control system 3 is tightly connected to the frame 1, the control system 3 is used to control the actions of the detection mechanism 4 and the grinding mechanism 5, the detection mechanism 4 and the grinding mechanism 5 are arranged in sequence along the conveying direction of the workpiece, the detection mechanism 4 is tightly connected to the frame 1, the detection mechanism 4 is used to detect the position of rust on the surface of the workpiece, the grinding mechanism 5 is tightly connected to the frame 1, and the grinding mechanism 5 is used to remove rust on the surface of the workpiece.

[0037] The workpiece processed by the present invention is a wire from which most of the oxide layer has been removed by repeated bending. The stubborn rust remaining on the surface of the wire is polished, and the workpiece is sent into the rust removal device for treatment through the corresponding traction mechanism. The traction mechanism is a prior art and will not be described in detail here. The frame 1 is used to provide a stable working environment for each mechanism. The workpiece entering the rust removal device is first guided by the guide mechanism 2 so that the movement path of the workpiece tends to be stable, and then passes through the detection mechanism 4 and the polishing mechanism 5 in turn. The detection mechanism 4 can detect the position of the rust on the surface of the workpiece, and then the control system 3 controls the polishing mechanism 5 to accurately polish the rust, thereby improving the efficiency of rust treatment.

[0038] The detection mechanism 4 includes a fixed ring 41, a guide ring 42 and a detection component 43. The fixed ring 41 is tightly connected to the frame 1, the guide ring 42 is tightly connected to the fixed ring 41, the guide ring 42 is located in the inner ring of the fixed ring 41, the detection component 43 is slidably connected to the guide ring 42, and the detection component 43 is used to detect rust on the surface of the workpiece.

[0039] The fixing ring 41 is fixed on the frame 1 to provide an installation basis for the detection mechanism 4, and the guide ring 42 can guide the detection component 43 so that the detection component 43 is close to the surface of the workpiece, thereby facilitating the detection component 43 to detect the rust position on the surface of the workpiece.

[0040] The detection assembly 43 includes a detection block 431 and a support spring 432. A guide groove 421 is provided on the guide ring 42. The detection block 431 is slidably connected to the guide groove 421. One end of the support spring 432 is tightly connected to the detection block 431, and the other end of the support spring 432 is tightly connected to the inner wall of the guide groove 421. The support spring 432 is located on the side of the guide groove 421 close to the grinding mechanism 5. The detection block 431 is arc-shaped. Several detection blocks 431 are arranged along the inner ring of the guide ring 42. Several detection blocks 431 form a complete detection ring. The inner diameter of the detection ring is the same as the outer diameter of the workpiece, and the contact surface between the detection ring and the workpiece is smooth.

[0041] Because there are several detection blocks 431 arranged along the inner ring of the guide ring 42, and they form a complete detection ring with the same outer diameter as the workpiece, the inner ring of the detection ring will abut the surface of the workpiece, and there are gaps between the detection blocks 431, so that relative movement can be performed. The workpiece passes through the rust removal device at a certain speed, and the rusted position on the workpiece surface is relatively rough, while the position without rust is relatively smooth. That is, when the rusted position passes through the detection block 431 at the corresponding position, the friction force on the detection block 431 is greater than that without rust, which will drive the detection block 431 at this position to slide along the guide groove 421, and the support spring 432 is compressed, and the sliding direction is the same as the movement direction of the workpiece. By detecting which area the detection block 431 is If the rust on the workpiece moves, the position of the rust on the workpiece can be determined; in addition, if the rust on the workpiece surface is longer, the friction will continue to act on the detection block 431 for a period of time, so that the detection block 431 maintains an offset state for a certain period of time, and the length of the rust on the workpiece surface can be determined by detecting the offset time of the detection block 431 in this area. The longer the offset time of the detection block 431, the longer the rust on the workpiece surface; and, if the rust on the workpiece is rougher, the greater the friction on the detection block 431, and the longer the distance that the detection block 431 slides along the guide groove 421. The roughness of the rust can be determined by detecting the moving distance of the detection block 431. The longer the offset distance of the detection block 431, the greater the roughness of the rust.

[0042] The detection assembly 43 also includes a first telescopic rod 433, a connecting block 434, a second telescopic rod 435, a slider 436, an iron core 437, a repelling magnet 438 and a pressure strain gauge 439. One end of the first telescopic rod 433 is hinged to the detection block 431, the other end of the first telescopic rod 433 is fastened to the connecting block 434, one end of the second telescopic rod 435 is fastened to the connecting block 434, the other end of the second telescopic rod 435 is hinged to the slider 436, and a support frame 422 is provided on the guide ring 42. The connecting block 434 is rotatably connected to the support frame 422, and the fixed The ring 41 is provided with a slide groove 411 and a detection cavity 412. The detection cavity 412 is located at one end of the slide groove 411 away from the grinding mechanism 5. The slider 436 is slidably connected to the slide groove 411. The iron core 437 is tightly connected to the slider 436. The iron core 437 faces the detection cavity 412. The pressure strain gauge 439 is tightly connected to the inner wall of the detection cavity 412. The pressure strain gauge 439 is electrically connected to the control system 3. The repelling magnet 438 abuts against the detection surface of the pressure strain gauge 439. A coil 44 is wound around one end of the slide groove 411 close to the detection cavity 412, and the coil 44 is externally connected to a power supply.

[0043] During detection: the iron core 437 is inserted into the coil 44 to form an electromagnet, and the facing surfaces of the electromagnet and the repelling magnet 438 are the same magnetic poles.

[0044] When the detection block 431 is offset along the guide groove 421 due to the action of rust on the surface of the workpiece, it will drive the first telescopic rod 433 hinged to the detection block 431 to deflect, and then drive the connecting block 434 to rotate around the support frame 422, so that the second telescopic rod 435 fixed to the connecting block 434 deflects to the other side, and then drives the slider 436 hinged to the second telescopic rod 435 to move along the slide groove 411 toward the detection cavity 412, so that the iron core 437 is inserted into the coil 44 to form an electromagnet. Because the facing ends of the electromagnet and the repelling magnet 438 are the same magnetic poles, according to the principle of like poles repelling each other, the electromagnet will exert a thrust on the repelling magnet 438, so that the pressure strain gauge 439 is compressed. As the flow cross-section decreases, the resistance value will increase; and, if the rust on the surface of the workpiece is rougher, the longer the offset distance of the detection block 431, the longer the offset distance of the second telescopic rod 435, the longer the distance the iron core 437 is inserted into the coil 44, the greater the thrust of the electromagnet on the repelling magnet 438, and the greater the resistance value of the pressure strain gauge 439, that is, the greater the roughness of the rust on the surface of the workpiece, the greater the resistance value of the pressure strain gauge 439; in addition, if the rust on the surface of the workpiece is longer, the longer the offset time of the detection block 431, the longer the time the iron core 437 is inserted into the coil 44, and the longer the resistance value of the pressure strain gauge 439 is maintained, that is, the longer the rust on the surface of the workpiece, the longer the resistance value of the pressure strain gauge 439 is maintained.

[0045] The length of the second telescopic rod 435 is greater than the length of the first telescopic rod 433 .

[0046] The detection block 431 is offset by a small distance under the action of friction and is difficult to detect. The first telescopic rod 433, the connecting block 434 and the second telescopic rod 435 form a lever structure with the connecting block 434 as the rotation center, which amplifies the offset distance of the detection block 431, thereby facilitating subsequent detection.

[0047] The grinding mechanism 5 includes a connecting ring 51, an electric push rod 52 and a grinding block 53. The connecting ring 51 is tightly connected to the frame 1, the electric push rod 52 is tightly connected to the connecting ring 51, and the output end of the electric push rod 52 is transmission connected to the grinding block 53. The grinding blocks 53 are arranged in several groups along the inner circle of the connecting ring 51. Several grinding blocks 53 form a complete grinding ring, and the positions of the several grinding blocks 53 correspond one by one to the positions of the several detection blocks 431.

[0048] The connecting ring 51 is fixed on the frame 1 to provide support for the grinding mechanism 5. The diameter of the grinding ring composed of several grinding blocks 53 is larger than the diameter of the workpiece. Under normal conditions, the grinding blocks 53 do not contact the surface of the workpiece. When the detection mechanism 4 detects that there is rust in a certain area on the surface of the workpiece, the position of the detection block 431 at the corresponding position will be offset, and the electric push rod 52 at the corresponding position is started by the control system 3, so that the grinding surface of the grinding block 53 at the corresponding position is attached to the surface of the workpiece, and the rust on the surface of the workpiece is polished, that is, the automatic positioning of the rust position is realized, thereby improving the grinding efficiency; and the rougher the rust on the surface of the workpiece, the higher the control speed. The greater the resistance of the pressure strain gauge 439 detected by the system 3, the greater the grinding pressure applied by the electric push rod 52, that is, the automatic adjustment of the grinding pressure according to the roughness of the workpiece surface is realized, thereby improving the grinding effect; in addition, the longer the rust on the workpiece surface, the longer the offset time of the detection block 431, the longer the time the iron core 437 is inserted into the coil 44, and the longer the resistance of the pressure strain gauge 439 is maintained. The time that the electric push rod 52 maintains the grinding state under the control of the control system 3 is increased accordingly, that is, the automatic control of the grinding time is realized according to the length of the rust on the workpiece surface, thereby reducing the wear of the grinding block.

[0049] The grinding block 53 is in an arc shape and is made of a flexible material.

[0050] The arc-shaped flexible grinding block 53 can be attached to the surface of the workpiece, thereby ensuring the grinding effect.

[0051] The guide mechanism 2 is arranged at the feed port and the discharge port of the frame 1 . The guide mechanism 2 includes a guide wheel 21 and a rotating shaft 22 . The guide wheel 21 is fixedly connected to the rotating shaft 22 , and the rotating shaft 22 is rotatably connected to the frame 1 .

[0052] The two sets of guide mechanisms 2 are respectively arranged at the feed port and the discharge port of the frame 1. The workpiece is guided by the guide wheels 21 arranged up and down so that the workpiece passes through the detection mechanism 4 and the grinding mechanism 5 in a stable state. The rotating shaft 22 serves as the rotation basis of the guide wheel 21.

[0053] The working principle of the present invention is as follows: the workpiece passes through the rust removal device at a certain speed. Under normal conditions, the grinding block 53 does not contact the surface of the workpiece. When the detection mechanism 4 detects that there is rust on a certain area on the surface of the workpiece, the detection block 431 at this position will be driven to slide along the guide groove 421 under the action of friction force, and the support spring 432 will be compressed, thereby driving the first telescopic rod 433 hinged to the detection block 431 to deflect, and then driving the connecting block 434 to rotate around the supporting frame 422, so that the second telescopic rod 435 fixedly connected to the connecting block 434 deflects to the other side, and then drives the slider 436 hinged to the second telescopic rod 435 to move along the slide groove 411 toward the detection cavity 412, so that the iron core 437 is inserted into the coil 44 to form an electromagnet. According to the principle of like charges repel each other, the electromagnet will exert a thrust on the repelling magnet 438, so that the pressure strain gauge 439 is compressed, the flow cross section of the pressure strain gauge 439 is reduced, and the resistance value is increased; The control system 3 is used to start the electric push rod 52 at the corresponding position, so that the grinding surface of the grinding block 53 at the corresponding position is attached to the surface of the workpiece, and the rust on the surface of the workpiece is ground, that is, the automatic positioning of the rust position is realized, thereby improving the grinding efficiency; and the rougher the rust on the surface of the workpiece, the greater the resistance of the pressure strain gauge 439 detected by the control system 3, and the grinding pressure applied by the electric push rod 52 is increased accordingly, that is, the automatic adjustment of the grinding pressure according to the roughness of the workpiece surface is realized, thereby improving the grinding effect; in addition, the longer the rust on the surface of the workpiece, the longer the offset time of the detection block 431, the longer the time the iron core 437 is inserted into the coil 44, the longer the resistance of the pressure strain gauge 439 is maintained, and the time that the electric push rod 52 maintains the grinding state under the control of the control system 3 is correspondingly increased, that is, the automatic control of the grinding time according to the length of the rust on the surface of the workpiece is realized, thereby reducing the wear of the grinding block.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
