Technical Field

[0001] The present invention relates to the technical field of hot isostatic pressing equipment, and in particular to a loading and unloading device and a loading and unloading method for a hot isostatic pressing machine. Background Art

[0002] A hot isostatic press utilizes hot isostatic pressing technology to create high-density parts by applying high temperature and uniform isostatic pressure to the workpiece in a sealed container at high temperature and pressure, using high-pressure argon as the medium. With the current trend of HIP parts becoming larger and larger, the trend of hot isostatic presses towards larger sizes is inevitable.

[0003] The hot isostatic press adopts the top loading type. When loading or discharging the hot isostatic press, it is impossible to observe the power connection status at the bottom of the electric furnace. This requires the external tooling to ensure the precise positioning of the bottom electric furnace.

[0004] During the hot isostatic pressing (HIP) production process, both loading and unloading require tooling. The diameter and height of large HIP equipment far exceed the operational range of a single person working in a fixed station. Existing tooling requires manual locking and opening, necessitating the deployment of workers in various positions and at varying working heights. This creates inconvenience, requires significant manpower input, and results in low efficiency. Furthermore, operating at height presents certain risks, posing a significant safety hazard.

[0005] In the hot isostatic pressing production process, there is an urgent need for a loading and unloading device that can position itself, lock or open the tooling through simple operations, and facilitate manual operation. Summary of the Invention

[0051] The following is combined with Figures 1 to 13 , the present invention is further described with specific examples:

[0057] The top plate assembly 11 includes an upper top plate 111 and a hoisting unit 112 .

[0058] like Figure 10 As shown, in this specific embodiment, the upper top plate 111 is a plate, and upper connecting rod through holes 1112 for the upper connecting rods 2211 to pass through are evenly distributed on the circumference of the upper top plate 111; optionally, a hoisting unit installation hole 1111 is also provided.

[0060] like Figure 11 As shown, the bottom plate 12 is a plate with a feed hole 124 in the center and lower connecting rod through holes 121 corresponding to the upper connecting rod through holes 1112 evenly distributed around the bottom plate; optionally, a fixing rod embedded hole 122 for welding the fixing rod 13 and a self-locking positioning body installation unit 123 are also provided; the self-locking positioning body installation unit 123 is a hole or a screw hole.

[0061] In this embodiment, the fixing rod 13 can be a steel rod or a round steel tube, which can be circumferentially welded to the lower end surface of the upper top plate 111 and the upper end surface of the bottom plate 12. Alternatively, countersunk holes or through-holes can be provided on the lower end surface of the upper top plate 111 and the bottom plate 12 for welding, or the fixing rod 13 can be screwed together. After screwing, the fixing rod 13 can be further circumferentially welded to form a stable cage-shaped mounting assembly.

[0062] Specifically, in this embodiment, the upper plate 111 is a circular steel plate with a hoisting unit mounting hole 1111 disposed at its center to allow for the hook body 1122 to pass through. The bottom plate 12 is a circular steel plate with the same structure as the upper plate 111, and a self-locking positioning body 22224 is fixed thereon above the lower connecting rod through hole 121.

[0063] like Figure 5 As shown, each connecting rod assembly 22 includes an upper connecting rod unit 221 and a lower connecting rod unit 222; the upper connecting rod unit 221 and the lower connecting rod unit 222 are detachably fixed; the upper end of the upper connecting rod unit 221 passes through the upper connecting rod through hole 1112 on the upper top plate 111, is fixed to the rotating assembly 21, and rotates with the rotating assembly 21; the lower end of the lower connecting rod unit 222 passes through the lower connecting rod through hole 121 on the bottom plate 12, and is fixed to the lock tongue component 3.

[0064] The upper connecting rod unit 221 comprises an upper connecting rod 2211 and a lower handle unit 2212 hingedly connected to the lower portion of the upper connecting rod 2211. The lower end of the upper connecting rod is provided with an upper connecting rod lower connecting portion 2213 that is detachably connected to the lower connecting rod unit 222. The lower handle unit 2212 is preferably a three-sided frame structure, with two opposing sides rotatably connected to the upper connecting rod 2211 via hinges. When not in use, the lower handle unit 2212 is integrally buckled onto the upper connecting rod 2211. When in use, it can be flattened to serve as a handle, driving the upper connecting rod 2211 to rotate.

[0065] Preferably, the upper connecting rod 2211 is made of steel rod, and a stepped column is provided at the lower end as the main body of the upper connecting rod lower connecting part 2213; an axially long radial through hole is provided at the end of the upper connecting rod lower connecting part 2213 as the axial displacement through hole 22131. The axially long radial through hole is used to connect the lower connecting rod unit 222, and can realize the axial displacement adjustment between the upper connecting rod unit 221 and the lower connecting rod unit 222 before and after self-locking, such as Figure 7 shown.

[0066] Optionally, the axially elongated radial through-holes are also provided on the lower connecting rod 2221; correspondingly, the upper connecting rod 2211 is provided with radial through-holes. This helps to enhance the overall strength of the connecting rod assembly and prevents breakage of the lower connecting rod 2221. Furthermore, the connecting rod connector 2231 can also adopt a non-rotating structure, such as a square rod or square tube.

[0067] The lower connecting rod unit 222 includes a lower connecting rod 2221 and a self-unlocking unit 2222. The upper end of the lower connecting rod 2221 is provided with an axial blind hole as the lower connecting rod upper connecting portion 22211, and a radial through hole is provided near the end as the lower connecting rod upper radial through hole 22212.

[0068] Preferably, the pillow block of the lower connecting part 2213 of the upper connecting rod is inserted into the blind hole of the upper connecting part 22211 of the lower connecting rod, and a connecting rod connecting body 2231 is provided to pass through the radial through hole 22212 and the axial displacement through hole 22131 on the lower connecting rod, and the lower connecting rod unit 222 and the upper connecting rod unit 221 are movably connected into one through the connecting rod positioning bodies 2232 at both ends. The connection can adjust the axial position of the lower connecting rod unit 222 and the upper connecting rod unit 221 within the range of the radial through hole of the axial strip of the axial displacement through hole 22131.

[0069] Specifically, in this embodiment, the lower end of the lower connecting rod 2221 is provided with a lower connecting rod lower threaded portion 22213 for screwing the lock tongue component 3; and further includes a lower connecting rod middle threaded portion 22214 provided in the middle portion for connecting the self-unlocking unit 2222;

[0070] Preferably, the upper connecting portion 22211 of the lower connecting rod is a blind hole provided at the upper end of the lower connecting rod 2221, on which the lower connecting rod upper radial through hole 22212 is provided; the lower connecting portion 2213 of the upper connecting rod is a pillow block provided at the lower end of the upper connecting rod 2211, on which a radial through hole is provided; the lower connecting portion 2213 of the upper connecting rod is inserted into the upper connecting portion 22211 of the lower connecting rod, and the lower connecting rod upper radial through hole 22212 and the axial displacement through hole 22131 are connected through the through hole, into which the connecting rod connecting body 2231 is inserted, and both ends or one end are limited by the connecting rod positioning body 2232. Preferably, the connecting rod connecting body 2231 is a pin, and the connecting rod positioning body 2232 is a cotter pin.

[0071] like Figure 6 、 Figure 8 、 Figure 9 As shown, the self-locking unit 2222 includes a self-locking nut 22221, a self-locking sleeve 22222, a self-locking spring 22223 and a self-locking positioning body 22224; the self-locking nut 22221 is screwed into the threaded portion 22214 of the lower connecting rod; the self-locking sleeve 22222 is located at the lower part of the self-locking nut 22221, and a wrench clamping portion is provided on the outside and a stepped hole is provided on the inside; the stepped hole is divided into a self-locking sleeve small hole portion and a self-locking sleeve large hole portion; wherein, the self-locking sleeve small hole portion is provided with an internal thread, which is connected to the threaded portion 22214 of the lower connecting rod; the self-locking sleeve large hole portion accommodates the self-locking spring 22223, and the lower end surface is provided with a self-locking sleeve clamping groove 222221.

[0072] Specifically, the threaded portion 22214 in the lower connecting rod is used to sequentially thread the self-locking nut 22221 and the self-locking sleeve 22222. The small hole portion of the self-locking sleeve is provided with a matching internal thread.

[0073] Specific as Figure 6 Shown below.

[0074] Specifically, the lower portion of the self-locking spring 22223 abuts against the upper end surface of the base plate 12; a connecting rod self-locking positioning body 22224 is fixed to the upper end surface of the base plate 12 to ensure that the self-locking sleeve 222221 is located in the working position of the hot isostatic press loading and unloading device, and that the self-locking sleeve 22222 does not contact the upper end surface of the base plate 12 when the upper end surface of the self-locking positioning body 22224 does not contact the bottom surface of the self-locking sleeve 222221 in the lower limit position. The connecting rod self-locking positioning body 22224 is used to limit the axial rotation of the lower connecting rod unit 222 at the two extreme rotation angle positions.

[0075] Specifically, the self-locking positioning body 22224 is a steel column or a hexagonal bolt, which is fixed to the base plate 12; accordingly, a blind hole or a screw hole is provided on the upper end surface of the base plate 12 as the self-locking positioning body mounting unit 123. In this embodiment, the self-locking positioning body 22224 is preferably a hexagonal bolt, and the self-locking positioning body mounting unit 123 is a screw hole.

[0076] The bolt component 3 is L-shaped, with a bolt connection portion 31 at the vertical end and a bolt support portion 32 at the flat end. The upper end surface of the bolt connection portion 31 is provided with a bolt connection unit 311, preferably a threaded hole, which is threadedly connected to the lower connecting rod lower threaded portion 22213 at the lower end of the lower connecting rod 2221. The bolt connection portion 31 is provided with a fastening unit 312 that extends through the bolt connection unit 311 and is used to mount a bolt fastening member 33. This secures the lower connecting rod lower threaded portion 22213 to the bolt connection unit 311, ensuring the secure connection of the bolt component 3. The preferred bolt fastening member 33 is a flat-ended set screw.

[0077] Preferably, the lock tongue supporting portion 32 is provided with an arc platform 321, such as Figure 13 As shown. When loading material in the device of the present invention, the outer surface of the workpiece is axially positioned by the arc tops of the multiple arc platforms 321 on the lock tongue component 3. Due to the provision of the arc platforms 321, the outer surface of the workpiece is precisely positioned circumferentially relative to the lock tongue component 3, ensuring a more stable position of the workpiece in the device. In addition, the arc of the arc platform 321 is arranged with the center of the hole of the lock tongue connecting unit, which allows the lock tongue component 3 to rotate smoothly, and prevents the lock tongue component 3 from being unable to rotate due to interference between the straight edge of the lock tongue connecting portion 32 and the workpiece.

[0078] The rotating assembly 21 includes a first rotating unit 211, a second rotating unit 212, and a rotation limiting unit 213. The second rotating unit 212 is fixedly connected to the upper connecting rod 2211. The first rotating unit 211 and the plurality of second rotating units 212 form a rotating pair; the rotation of one first rotating unit 211 can drive the plurality of second rotating units 212 to rotate simultaneously.

[0079] The rotation limit unit 213 is used to limit the rotation angle range of the second rotation unit 212 to 90°, so as to ensure that the lock tongue support part 32 on the lock tongue component 3 is correspondingly located in the tangential position non-loading state and the radial position loading state of the base plate 12 when it is at the two extreme positions of the rotation angle of the second rotation unit 212.

[0080] The rotation limiting unit 213 includes a rotation unit base 2131 and a limiting post 2132 mounted on the rotation unit base 2131. The rotation unit base 2131 is provided with a base through-hole 21311, which is loosely fitted to allow the upper connecting rod 2211 to pass through. In this embodiment, four sets of rotation limiting units 213 are preferably evenly distributed and fixedly connected to the periphery of the upper top plate 111.

[0081] like Figure 12 As shown, preferably, the rotating unit base 2131 adopts a rectangular steel plate, on which a base through hole 21311 is provided; an annular plunger raceway 21313 is provided within a range of 90° with this as the center, the depth of which is less than the radius of the plunger ball, and two brake ball sockets 21314 are provided at the two extreme positions, and two limit column mounting holes 21312 are provided correspondingly on the outer side of the brake ball sockets 21314 for fixing the limit column 2132.

[0082] Specifically, when the second rotating unit 212 rotates and is restrained at the stopper 213, the ball at the bottom of the plunger 2123 is positioned to precisely enter the detent ball socket 21314. At this point, the tongue support 32 of the tongue lock component 3 is positioned radially or tangentially relative to the base plate 12, braking the entire rotating component. The stopper 2132 can be understood as a secondary mechanical stop; its function is to prevent the tongue lock component 3 from rotating excessively even if the plunger 2123 fails to achieve its desired position.

[0083] The second rotating unit 212 includes a rotating body 2121 and a driven pair 2122 ; the upper connecting rod 2211 is fixedly connected to the driven pair 2122 , or is fixedly connected to the rotating body 2121 and the driven pair 2122 respectively.

[0084] Optionally, the revolving pair may be a connecting rod pair, a gear pair, or other forms of revolving pairs.

[0085] First embodiment:

[0086] like Figure 1 As shown, the first embodiment adopts two first rotating units 211 , and each first rotating unit 211 is rotatably connected to a second rotating unit 212 at both ends to form two planar linkage mechanisms.

[0087] Optionally, the rotating body 2121 is a rotating sleeve, and the driven pair 2122 is a short plate. Specifically, the rotating sleeve of the rotating body 2121 is fixedly connected to the base through-hole 21311 on the rotating unit base 2131, and is connected to one end of the short plate of the driven pair 2122 via an upwardly spaced sliding member. The upper connecting rod 2211 passes through the upper top plate 111 and the rotating sleeve of the rotating body 2121, and is fixedly connected to one end of the short plate of the driven pair 2122. The short plate rotates on the upper end surface of the rotating body 2121, driving the upper connecting rod 2211 to rotate.

[0088] A plunger body 2123 is fixed downwardly to the middle of the short plate. When the ball at the lower end of the plunger body 2123 rolls in the plunger raceway 21313, the rotating component drives the tongue lock component 3 to rotate. When the ball at the lower end of the plunger body 2123 enters the braking ball socket 21314, the lock tongue support portion 32 of the tongue lock component 3 is located in the radial or tangential direction of the base plate 12, thereby braking the entire rotating component.

[0089] The other end of the short plate is provided with a hole-shaped connection structure, which is rotatably connected to one end of the first rotating unit 211 to form a rotating pair.

[0090] In this embodiment, the first rotating unit 211 is preferably a long plate active pair 2111 , with shaft holes provided at both ends of the active pair 2111 , which is rotatably connected to the two second rotating units 212 via two rotating secondary shafts 214 .

[0091] Preferably, an upper handle 215 is provided on the upper end surface of the active pair 2111 at the rotating secondary shaft 214 .

[0092] Second embodiment:

[0093] like Figure 2 As shown, the second embodiment uses one first rotating unit 211 to drive four second rotating units 212 to rotate, forming a planar linkage mechanism.

[0094] The difference from the first embodiment is that the first rotating unit 211 is formed by a connecting pair 2112 that connects the diagonal ends of the two active pairs 2111 to the rotating secondary shaft 214, so that the two active pairs 2111 can be linked simultaneously. Preferably, the connecting pair 2112 is a long plate, and its shape needs to avoid interfering parts, such as Figure 1 shown.

[0095] The first rotating unit 211 can also be of other structural forms. For example, a circular plate can be used as a driving pair 2111 at the four rotating secondary shafts 214 to rotate the driven pair 2122 connected to the four short plates. An upper handle 215 can also be provided on the circular plate.

[0096] Third embodiment:

[0097] like Figure 3 As shown, the third embodiment uses a gear pair. This structure is not affected by the odd or even number of rotating components, and any number of rotating components can be set according to the load requirement to achieve linkage.

[0098] Specifically, the rotating body 2121 on the second rotating unit 212 is set as an external gear. The external gear of the rotating body 2121 is fixedly connected to the upper connecting rod 2211 through a key. The upper end of the upper connecting rod 2211 is still fixedly connected to one end of the short plate of the driven pair 2122 so as to simultaneously limit the rotation within a 90° angle range.

[0099] Optionally, the other end of the short plate is fixedly connected to the upper handle 215.

[0100] Optionally, rolling elements are provided on the upper and lower end surfaces of the outer gear of the rotating body 2121 to reduce rotational friction.

[0101] The first rotating unit 211 of the third embodiment is designed as an internal gear, which is meshed with the external gears of the rotating bodies 2121 on the four second rotating units 212 to form a planetary gear structure.

[0102] Optionally, rolling bodies are provided on the upper and lower end surfaces of the internal gear of the first rotating unit 211 to reduce rotational friction.

[0103] The gear pair can also be replaced by a rotating pair in the form of a belt drive.

[0104] The positioning components include an upper positioning assembly 41 and a lower positioning assembly 42; the upper positioning assembly 41 is fixedly connected to the upper end surface of the upper top plate 111, including an upper positioning mounting body and an upper positioning body; the lower positioning assembly 42 is fixedly connected to the lower end surface of the base plate 12, including a lower positioning mounting body and a lower positioning body.

[0105] Preferably, each positioning mounting body and the positioning body are screwed together, which makes the upper positioning assembly 41 and the lower positioning assembly 42 adjustable parts and can also achieve axial fine adjustment. Figure 3 Shown in the lower left corner.

[0106] The adjustable positioning unit is used to determine the position with the surrounding equipment to ensure that the loading and unloading device for the hot isostatic press of the present invention is hoisted into the correct angle.

[0107] Specifically, the loading and unloading device for the hot isostatic press is hoisted to a designated position on the upper part of the hot isostatic press and slowly fed into the hot isostatic press furnace to achieve the coaxiality of the device with the hot isostatic press furnace; after the device is lowered to a certain height, the positioning body of the upper positioning component 41 is used to correspond to the hole on the end face of the hot isostatic press furnace to achieve the angular positioning of the device of the present invention on the hot isostatic press furnace; the positioning body of the lower positioning component 42 is used to contact the bottom surface of the hot isostatic pressing container to achieve the height positioning of the loading and unloading device for the hot isostatic press of the present invention, and the height direction of the furnace core can also be adjusted and positioned on different heating furnaces.

[0108] More specifically, the lower positioning body of the lower positioning assembly 42 is screwed onto the lower positioning mounting body, which can facilitate adjustment of the length of the positioning body, compensate for assembly errors of the device, and ensure the positioning accuracy of the lock tongue.

[0109] The method of using a hot isostatic press loading and unloading device to load and unload materials includes a loading step and a unloading step.

[0110] A method for charging using a hot isostatic press loading and unloading device is as follows:

[0111] S1. Use the loading and unloading device of the hot isostatic press to grab the materials in the work area:

[0112] In the working area, the lower handle unit 2212 is flattened and rotated horizontally to rotate the lock tongue support portion 32 to a tangential position located at the bottom plate 12, so that the device of the present invention is in a non-loading state;

[0113] The device of the present invention is hoisted into the work area so that the work materials enter the interior of the cage-shaped installation component from the bottom of the device of the present invention;

[0114] At this time, in order to work on the ground, the lower handle unit 2212 is flattened and rotated horizontally 90°. The upper connecting rod 2211 drives the rotating component to rotate 90°, so that the lock tongue support part 32 is rotated from the tangential position of the base plate 12 to the radial centripetal direction of the base plate 12, and is in a loading state.

[0115] S2. Loading the hot isostatic press Use the loading and unloading device to transport the working materials to the hot isostatic press:

[0116] The crane lifts the hot isostatic press loading and unloading device of the present invention;

[0117] At this time, the weight of the workpiece acts on the lock tongue component 3, causing it to move downward; the lock tongue component 3 pulls the entire connecting rod assembly 22 downward; at this time, the long radial through hole 22131 that is axially displaced causes the lower connecting rod unit 222 to make an axial displacement relative to the mounting component; this displacement causes the self-unlocking unit 2222 to move downward as a whole at the bottom, and the self-locking spring 22223 is compressed, causing the self-locking positioning body 22224 to enter the self-locking sleeve slot 222221 of the self-locking sleeve 22222; this ensures that the connecting rod assembly 22 cannot rotate during the lifting process, realizing the self-locking function, thereby preventing the lock tongue component from falling out and ensuring the safe transportation of the workpiece to the hot isostatic press. At this time, the plunger body 2123 rotates smoothly in conjunction with the second rotating unit 212, and under the restriction of the rotation limit unit 213, the marble enters the braking ball socket 21314. At this time, the lock tongue support portion 32 of the lock tongue component 3 is in the radial direction of the base plate 12, and the entire rotating component is braked.

[0118] S3. Feed the workpiece into the hot isostatic press:

[0119] The loading and unloading device of the hot isostatic press carrying the work material is hoisted into the correct feeding position;

[0120] charging the furnace;

[0121] The lower positioning device 42 is used to ensure that the loading and unloading device of the hot isostatic press carrying the work material can achieve the correct discharge angle.

[0122] S4. Unload the work material into the hot isostatic press and lift the hot isostatic press away from the hot isostatic press using a loading and unloading device:

[0123] Since the work material has been put into the correct position in the furnace, the loading and unloading device of the hot isostatic press is no longer affected by the gravity of the work material, the self-locking spring 22223 is recovered to its original state, the lock tongue component 3 moves up, the lower connecting rod unit 222 moves back to its original position as a whole, the self-locking sleeve slot 222221 of the self-locking sleeve 22222 returns to its original position, disengages from the self-locking positioning body 22224, and realizes automatic unlocking of the connecting rod assembly 22;

[0124] At this time, the upper handle 215 is pulled to realize the rotation of the connecting rod assembly 22. Specifically, the upper handle 215 is pulled (the first embodiment requires rotating the two upper handles 215 separately) so that the second rotating unit 212 rotates 90° to the other extreme position. At this time, the plunger body 2123 rotates smoothly in conjunction with the second rotating unit 212, and under the restriction of the rotation limit unit 213, the marble enters the braking ball socket 21314. At this time, the lock tongue support portion 32 of the tongue lock component 3 is in the tangential direction of the bottom plate 12, and the entire rotating component is braked in a non-loading state;

[0125] The crane lifts the unloaded hot isostatic press apparatus of the present invention and leaves the hot isostatic press.

[0126] The loading process is completed.

[0127] A method for taking out materials using a loading and unloading device for a hot isostatic press is as follows:

[0128] S1, feeding the hot isostatic press in a non-loaded state into the hot isostatic press using a loading and unloading device;

[0129] Use a lifting device to lift the loading and unloading device for the hot isostatic pressing machine to a designated position on the upper part of the hot isostatic pressing furnace; slowly send the device into the hot isostatic pressing furnace. The device of the present invention is coaxial with the hot isostatic pressing furnace. After the device is lowered to a certain height, the upper positioning component 41 is angularly positioned with the hole on the end face of the hot isostatic pressing furnace; slowly feed it in, and at this time the work material contacts the bottom surface of the hot isostatic pressing container from the lower positioning device of the loading and unloading device for the hot isostatic pressing machine; the lower positioning realizes the height positioning of the device.

[0130] S2. Lock the feeding so that the loading and unloading device of the hot isostatic press is in the loading state:

[0131] After the loading and unloading device for the hot isostatic press in the non-loading state enters the correct position in the hot isostatic press, the upper handle 215 is rotated (two upper handles 215 need to be rotated in the first embodiment) so that the locking tongue support portion 32 of the tongue locking component 3 is in the radial direction of the bottom plate 12, and the entire rotating component is braked in the loading state;

[0132] S3. Lift the device with the workpiece out of the hot isostatic press:

[0133] During this process, the self-unlocking unit 2222 is self-locked, the marble of the plunger body 2123 enters the brake ball socket 21314 for braking, and the hot isostatic press loading and unloading device is in the loading state.

[0134] S4. Unloading of materials in the work area, lifting the device away from the work area:

[0135] The hot isostatic press loading and unloading device is used to lift the loaded material to the work area; the work material is supported, the self-locking spring 22223 returns to its original state, the lock tongue component 3 moves upward, the lower connecting rod unit 222 moves upward and back to its position as a whole, the self-locking sleeve slot 222221 of the self-locking sleeve 22222 returns to its position, disengaging from the self-locking positioning body 22224, and realizing automatic unlocking of the connecting rod assembly 22;

[0136] At this time, pull up the lower handle unit 2212 and rotate it 90 degrees. The upper connecting rod 2211 drives the rotating component to rotate 90 degrees, so that the lock tongue support portion 32 rotates from the radial centripetal position of the bottom plate 12 to the tangential direction of the bottom plate 12. The entire rotating component is braked in a non-loading state.

[0137] The crane lifts the unloaded hot isostatic press loading and unloading device and leaves the work area.

[0138] The material removal process is completed.

[0139] The above are only preferred specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed by the present invention should be covered by the scope of protection of the present invention.
