Description

Technical Field

[0001] The invention relates to the technical field of metal forging, and in particular to a die steel blank forging detection control structure and a control method. Background Art

[0002] In the process of metal processing, forging is a very common processing technology, which mainly uses pressurized mechanisms such as air hammers and hydraulic hammers to forge and shape metal. Among them, the air hammer is a forging tool that uses compressed air to drive the piston, which can exert a strong impact force on the metal material, causing the metal material to undergo plastic deformation, thereby achieving the desired shape or size.

[0003] The invention patent application with the existing patent application number CN117483624A discloses an air hammer for forging, including a hammer body, a hammer head, an anvil and an anvil seat, wherein: the hammer body is arranged on the ground, the hammer head is installed on the upper part of the hammer body, the anvil seat is installed on the hammer body and is located directly below the hammer head, the anvil is installed on the anvil seat, and the blowing assembly is installed on the anvil.

[0004] As in the above technical solution, the material blank on the anvil is forged by a hammer head, and this forging structure is commonly used in existing air hammers; however, in the current forging process, forging workers are generally required to visually check whether the size of the material blank meets the standard, and then use calipers, feeler gauges and other tools to measure and determine. This measurement step affects the processing efficiency of forgings and poses safety risks; therefore, how to achieve efficient and automated detection of forgings is an effective measure to improve production efficiency and ensure the personal safety of workers;

[0005] In addition, due to the limitations of the driving structure of the air hammer, when the air hammer is on standby, the circulation of gas in the driving pipeline will cause the power hammer to have certain ups and down fluctuations. Therefore, by eliminating the influence of fluctuations, it is beneficial to accurately control the stroke of the power hammer and improve the processing accuracy. It can also make the blank forming standard and easy to detect. However, the existing scheme does not recognize this problem. Therefore, this application proposes relevant improvements to the existing technology. Summary of the invention

[0052] On the other hand, the present invention provides a blank forging control method, which uses the above-mentioned mold steel blank forging detection control structure, and includes the following steps:

[0053] S1, setting a reference height of the power hammer, and detecting a height fluctuation variable of the power hammer through a first detection component;

[0054] S2, inspecting the size of the mold through a third inspection component;

[0055] S3. Determine the corresponding blank processing steps according to the size information of the mold;

[0056] S4, driving the power hammer to forge the blank through the cylinder, and adjusting the opening of the rotary valve according to the height fluctuation variable of the power hammer to control the stroke of the power hammer;

[0057] S5. After the third detection component detects that the size of the blank is qualified, the forging is stopped.

[0058] The mold steel blank forging detection control structure and control method of the present invention have the following beneficial effects compared with the prior art:

[0059] (1) By arranging the first detection component and the third detection component on the forging machine, the stroke of the power hammer and the size of the die can be detected. Thus, the stroke of the power hammer and the height of the die are used as references to conveniently control the opening of the rotary valve, thereby controlling the force of the next forging to achieve good processing accuracy, which can avoid the problem of excessive forging causing the size of the blank to exceed the standard; and the second detection component can detect whether the size of the blank is qualified, and the forging can be stopped when it is qualified, so that the automatic detection of the blank is effectively realized, which is conducive to improving processing efficiency and reducing safety hazards;

[0060] (2) A third detection component is formed by setting a plurality of connecting rod type detection switches, and the mold is divided into a base and a baffle, wherein the length of the base and the diameter of the baffle are set in a fixed ratio; that is, in a plurality of molds, the length of the base is proportional to or inversely proportional to the diameter of the baffle. After the mold is replaced, the baffle contacts the third detection component, and the mold model and the model of the product to be processed can be quickly identified by the number of triggers of the connecting rod type detection switch, which also facilitates the air circuit control of the power hammer, thereby realizing the adjustment of the forging force and the number of times;

[0061] (3) A receiving groove is provided on the anvil for installing the laser emitter, and a detection hole is provided corresponding to the laser emitter. In this way, by using the cooperation between the laser emitter and the laser target, the size of the blank can be detected by opening and closing the optical path to determine whether the forging is qualified; at the same time, a gas supply channel connected to the receiving groove is opened on the anvil, and the detection hole is connected to the receiving groove. In this way, gas can be input through the gas supply channel and the gas will be output through the detection hole, so as to achieve cooling of the laser emitter to prevent high temperature from affecting the laser emitter. At the same time, an air curtain protection is formed to prevent the oxide layer from falling off and falling into the detection hole;

[0062] (4) The air supply channel has an air inlet section, an air outlet section and a stepped hole which are interconnected. A gas supply joint is provided in the stepped hole. The mold is configured to be plugged into the gas supply joint and is provided with a purge hole. Thus, when gas is input into the air supply channel, air is simultaneously supplied to the purge hole, which can realize the cleaning of the anvil table. At the same time, by providing a support sleeve in the mold and increasing the area for force transmission from the mold to the anvil, the rigidity of the mold can be effectively improved to avoid damage to the mold.

[0063] (5) By providing a cover shell and opening a through slot and an assembly slot on the top cover of the cover shell, interference with the installation of the second detection component and the third detection component can be avoided. Since the cover shell can rotate, the detection hole can be selectively blocked, which can further prevent the oxide layer of the raw material from falling off and falling into the detection hole.

[0064] (6) When the cover shell blocks the detection hole, the purge hole on the mold corresponds to the through groove. In this way, the part of the anvil corresponding to the through groove can be purged by air supply to avoid the deposition of the oxide layer of the embryo. When the cover shell is subsequently rotated to make the through groove correspond to the detection hole, the oxide layer of the embryo will not be pushed into the detection hole, so as to avoid affecting the normal operation of the second detection component.

DETAILED DESCRIPTION

[0080] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0081] like Figures 1 to 13 As shown, the mold steel blank forging detection control structure of the present invention includes a forging machine 1, a mold 2, a first detection component 3, a second detection component 4, a third detection component 5, a gas supply connector 6, a support sleeve 7 and a cover shell 8.

[0082] like Figure 1 As shown, the forging machine 1 includes a machine body 11, a cylinder 12, a power hammer 13 and an anvil 14, wherein the cylinder 12 is arranged on the machine body 11; the power hammer 13 is connected to the piston rod of the cylinder 12; the anvil 14 is arranged on the machine body 11 and corresponds to the power hammer 13;

[0083] The structure as described above is a conventional configuration of an air hammer forging machine, wherein the cylinder 12 is connected to an air path structure controlled by a rotary valve to achieve the descending forging, rising and hovering of the power hammer 13. An anvil 14 is also provided on the machine body 11 for supporting the blank to cooperate with the power hammer 13 to achieve forging work.

[0084] like Figure 1 and Figure 2As shown, the mold 2 is arranged on the anvil 14 for shaping the blank; the first detection component 3 is arranged on the machine body 11 for detecting the stroke of the power hammer 13; the second detection component 4 is arranged on the anvil 14 for detecting the processing size of the blank; the third detection component 5 is arranged on the anvil 14 for detecting the size of the mold 2;

[0085] As in the above structure, the first detection component 3 is used to detect the stroke of the power hammer 13, which can determine the initial point position and the total stroke of the power hammer 13, and the third detection component 5 can determine the model of the mold 2, and then determine the height of the mold 2. In this way, after placing the corresponding blank on the mold 2, it is convenient to adjust the opening of the rotary valve, and then adjust the forging force of the power hammer 13. According to the stroke detection of the power hammer 13, it can be used as a reference to calibrate the rotary valve card to adjust the next forging force, so as to achieve good processing accuracy and avoid the problem of excessive forging causing the blank size to exceed.

[0086] The second detection component 4 can detect whether the size of the blank is qualified, and forging can be stopped when it is qualified. This effectively realizes the automatic detection of the blank, which is beneficial to improve processing efficiency and reduce safety hazards.

[0087] Specifically, the first detection component 3 can be a detection device such as a laser detection component, a connecting rod type stroke detection device or a pull rope type stroke detection device.

[0088] like Figure 2 and Figure 3 As shown, the forging machine 1 further includes a guide rail 15 and a carrier 16, and the second detection assembly 4 includes a laser emitter 41, a laser target 42 and a temperature sensor 43, wherein the guide rail 15 is arranged on the machine body 11 and slidably cooperates with the power hammer 13; the carrier 16 is a ring-shaped structure and is detachably connected to the guide rail 15; the laser emitter 41 is arranged on the anvil 14; the laser target 42 is arranged on the carrier 16 to cooperate with the laser emitter 41; the temperature sensor 43 is arranged on the anvil 14;

[0089] As in the above structure, the guide rail 15 on the forging machine 1 is used to guide the power hammer 13 to ensure the stable movement of the power hammer 13; after the blank is placed on the mold 2, the power hammer 13 is controlled by the air circuit to achieve the forging action;

[0090] As the forging proceeds, the blank is deformed, and the laser emitter 41 and the laser target 42 are in a continuous detection state. When the blank is expanded in size due to forging and the light path is blocked, the laser target 42 cannot detect the light source, indicating that the blank forging size is qualified, and the forging is stopped at this time; thus, the automatic detection of the blank is realized, which can effectively improve the processing efficiency, and since no manual detection is required, the safety hazard is reduced;

[0091] Among them, the position of the temperature sensor 43 can be freely adjusted. First, it is used to detect the blank during the forging process. As the temperature changes, the opening of the rotary valve of the gas circuit is controlled to appropriately increase or decrease the forging force; second, it is arranged in parallel with the laser emitter 41. After the blank size is qualified, the temperature of the qualified blank is detected to determine whether the blank is suitable for continuing to the next step, thereby achieving good detection and control of the forging work.

[0092] Specifically, the temperature sensor 43 may be an infrared laser thermometer.

[0093] like Figure 2 and Figure 4 As shown, the carrier 16 includes a ring plate 161 and a connecting plate 162, wherein an embedding groove 1601 is provided on the inner side of the ring plate 161, and the embedding groove 1601 is clamped with the guide rail 15; the connecting plate 162 is arranged at the edge of the embedding groove 1601, and is connected to the guide rail 15 through a fastener; the laser target 42 is arranged on the ring plate 161;

[0094] As in the above structure, the carrier 16 is used to carry the laser target 42, which is engaged with the guide rail 15 through the embedded groove 1601 to achieve positioning, ensuring that the laser target 42 can be aligned with the laser emitter 41, and then connected and fixed with the guide rail 15 through the connecting plate 162 by bolts and other fasteners;

[0095] This structure realizes the detachable connection of the carrier 16 , facilitates the adjustment of the laser target 42 , and ensures the convenience of installation and positioning, while not interfering with the action of the power hammer 13 .

[0096] like Figure 6 , Figure 7 and Fig.13 As shown, the mold 2 includes a support 21 and a baffle 22, and the third detection assembly 5 includes a plurality of connecting rod type detection switches 51, wherein the support 21 is plugged into the anvil 14, the baffle 22 is arranged around the support 21, and the baffle 22 is spaced from the anvil 14; the support 21 partially extends to the side of the baffle 22 away from the anvil 14, and the length of the support 21 and the diameter of the baffle 22 are set in a fixed ratio; the anvil 14 is a cylindrical structure, and a plurality of connecting rod type detection switches 51 are arranged on the anvil 14 and arranged along the diameter line of the anvil 14;

[0097] As in the above structure, a third detection assembly 5 is formed by setting a plurality of connecting rod type detection switches 51, and the mold 2 is divided into two parts, namely, a support 21 and a baffle 22, wherein the length of the support 21 and the diameter of the baffle 22 are set in a fixed ratio; that is, in a plurality of molds 2, the length of the support 21 is proportional or inversely proportional to the diameter of the baffle 22;

[0098] Since a plurality of connecting rod type detection switches 51 are arranged along the diameter line of the anvil 14, after the mold 2 is replaced, the baffles 22 of different diameters contact different numbers of connecting rod type detection switches 51. After the diameter of the baffle 22 and the length of the mold 2 are proportionally corresponding, the model of the mold 2 and the model of the product to be processed corresponding to the mold 2 can be quickly identified by the number of triggering of the connecting rod type detection switches 51;

[0099] Specifically, the mold 2 is used for forging the same product. After obtaining the information of the mold 2, the size information of the blank to be processed can be obtained simultaneously, thereby controlling the forging force; a database with a corresponding relationship is established among the size of the mold 2, the size of the blank and the triggering number of the connecting rod detection switch 51, which is used for detection control.

[0100] In this way, after the initial position of the power hammer 13 is determined by the first detection component 3, and the height of the mold 2 and the parameters of the blank are detected by the third detection component 5, the opening of the rotary valve can be accurately adjusted, and the stroke of the power hammer 13 can be controlled by the air pressure, thereby adjusting the forging force;

[0101] Then, the stroke of the power hammer 13 is detected by the first detection component 3, and the next forging force is controlled, thereby realizing adaptive adjustment.

[0102] Specifically, the blank is suitable for an annular blank, which is forged by diameter expansion through the support platform 21, and the baffle 22 is used to support the blank after the diameter expansion.

[0103] like Figure 6 and Figure 7 As shown, the anvil 14 is provided with a receiving groove 1401, a detection hole 1402 and an air supply channel 1403, wherein the receiving groove 1401 is arranged on the circumferential surface of the anvil 14; the detection hole 1402 is opened along the axial direction of the anvil 14 and is connected with the receiving groove 1401, and one end of the detection hole 1402 passes through the anvil 14; the laser emitter 41 and the temperature sensor 43 are arranged in the receiving groove 1401 and extend into the detection hole 1402, and the aperture of the detection hole 1402 is larger than the diameter of the laser emitter 41 and the temperature sensor 43; the air supply channel 1403 is connected with the receiving groove 1401 and has a free port;

[0104] As in the above structure, a receiving groove 1401 is provided on the peripheral surface of the anvil 14, so that it is convenient to assemble the laser emitter 41 and the temperature sensor 43; during assembly, a bracket is provided in the receiving groove 1401, and the laser emitter 41 and the temperature sensor 43 are fixed on the bracket, and the laser emitter 41 and the temperature sensor 43 are aligned with the detection hole 1402;

[0105] The air supply channel 1403 opened on the anvil 14 is connected with the receiving groove 1401 and is provided with a free port. The free port is used to connect an air compressor to feed gas into the air supply channel 1403. At this time, the gas will enter the receiving groove 1401. Since the aperture of the detection hole 1402 is larger than the diameter of the laser emitter 41 and the temperature sensor 43, the gas will be output through the detection hole 1402 again, so as to achieve purging and cooling of the laser emitter 41 and the temperature sensor 43 to prevent high temperature from affecting the laser emitter 41 and the temperature sensor 43. At the same time, an air curtain protection will be formed to prevent the oxide layer from falling off and falling into the detection hole 1402, thereby ensuring that the detection can be carried out normally.

[0106] Specifically, the containing groove 1401 is closed to prevent gas leakage, so that the gas can be ejected upward through the detection hole 1402 .

[0107] like Figure 7 As shown, the air supply channel 1403 includes an air inlet section 14031, an air outlet section 14032, a stepped hole 14033 and a connecting section 14034, wherein the air inlet section 14031 is opened along the radial direction of the anvil 14 and has a free port that passes through the anvil 14; the air outlet section 14032 is opened along the axial direction of the anvil 14 and is connected to the air inlet section 14031; the stepped hole 14033 is opened along the axial direction of the anvil 14 and is connected to the air outlet section 14034. 4032 is connected to one end away from the air inlet section 14031; the connecting section 14034 is opened along the radial direction of the anvil 14, one end of the connecting section 14034 is connected to the air outlet section 14032, and the other end is connected to the accommodating groove 1401; the air supply connector 6 is arranged in the stepped hole 14033; the support platform 21 of the mold 2 is plugged with the air supply connector 6, and a plurality of purge holes 201 located between the baffle 22 and the anvil 14 are opened on the support platform 21;

[0108] As in the above structure, in the air supply channel 1403, a port of the air inlet section 14031 is connected to the outside of the anvil 14 for connecting to an air compressor. When the gas is pumped in, the gas is transported through the air outlet section 14032 and input into the containing tank 1401 through the connecting section 14034, so as to achieve purging and cooling of the laser emitter 41 and the temperature sensor 43;

[0109] At the same time, part of the air flow will flow through the air outlet section 14032 to the stepped hole 14033, and then enter the air supply connector 6 in the stepped hole 14033, and then enter the mold 2 through the air supply connector 6, and then be blown out through the purge hole 201, so as to purge the oxide layer of the embryo that falls on the anvil 14, thereby realizing self-cleaning.

[0110] In some embodiments, the purge hole 201 is arranged to correspond to the port of the detection hole 1402 to realize a purge protection function to prevent the oxide layer from falling into the detection hole 1402; in this embodiment, the connecting section 14034 may not be arranged.

[0111] like Figure 7 , Fig.11 and Fig.12 As shown, the stepped hole 14033 has a first stepped surface 140331, wherein the gas delivery connector 6 is a stepped cylindrical structure, the support platform 21 and the gas delivery connector 6 both abut against the first stepped surface 140331, and a second stepped surface 601 is formed inside the gas delivery connector 6; one end of the support sleeve 7 abuts against the second stepped surface 601, and the other end abuts against the inner wall of the mold 2, and the support sleeve 7 is provided with a connecting hole 701 corresponding to the purge hole 201;

[0112] As in the above structure, the stepped hole 14033 has a first stepped surface 140331, so that it can support the gas supply connector 6 and the support platform 21 of the mold 2, so as to ensure the stability of the structure; at the same time, the gas supply connector 6 is set as a stepped cylindrical structure, so that the inside thereof has a second stepped surface 601, and accordingly, a small diameter section and a large diameter section are formed on the outside of the gas supply connector 6, so that when connecting, the small diameter section of the stepped hole 14033 can be provided with an internal thread, and the small diameter section of the gas supply connector 6 can be provided with an external thread, so that the gas supply connector 6 can be connected to the anvil 14 through the threaded structure, which improves the convenience of assembly and also makes the external stepped surface of the gas supply connector 6 abut against the first stepped surface 140331, so as to ensure the stability of the structure;

[0113] Since the mold 2 is used to carry the blank and needs to withstand the forging pressure, a support sleeve 7 is provided inside the mold to improve the structural strength of the mold. The lower section of the support sleeve 7 abuts against the second step surface 601 of the gas delivery connector 6, and the upper section abuts against the inner wall of the mold 2, so that the forging pressure can be effectively transmitted to the anvil 14 to ensure the structural strength of the mold 2.

[0114] In order to prevent the layout of the support sleeve 7 from affecting the passage of gas, a connecting hole 701 is provided on the support sleeve 7 to ensure that the purge hole 201 can achieve the purge work;

[0115] Specifically, the top end of the support sleeve 7 is set as a closed structure to ensure the structural strength of the support sleeve 7, and the lower end is set as an open structure for gas circulation;

[0116] Specifically, at least a portion of the lower end surface of the support sleeve 7 corresponds to the first step surface 140331 through the second step surface 601, so as to achieve good transmission of the forging pressure.

[0117] like Figure 5 and Figures 8 to 10As shown, the cover shell 8 is rotatably connected to the anvil 14, and the cover shell 8 includes an inner shell 81, a top cover 82 and an outer shell 83, wherein the inner shell 81 is inserted into the stepped hole 14033 and abuts against the support 21; the top cover 82 fits the end surface of the anvil 14 and is connected to the inner shell 81, and a through groove 801 and an assembly groove 802 are opened on the top cover 82, and the third detection component 5 is assembled corresponding to the assembly groove 802; the outer shell 83 fits the peripheral surface of the anvil 14 and is connected to the top cover 82, and the outer shell 83 seals the accommodating groove 1401;

[0118] As in the above structure, the cover shell 8 is plugged into the stepped hole 14033 of the anvil 14 through the inner shell 81, so that the cover shell 8 and the anvil 14 are coaxial structures as a whole, which allows the cover shell 8 to rotate along the anvil 14;

[0119] The layout of the top cover 82 will cover the detection hole 1402, so a through slot 801 is opened on the top cover 82; when forging, the top cover 82 covers the detection hole 1402, and when testing, the top cover 82 is rotated so that the through slot 801 is aligned with the detection hole 1402, and the laser emitter 41 emits laser to cooperate with the laser target 42 for testing; in this testing mechanism, the laser emitter 41 does not continuously test, but emits laser for testing according to demand;

[0120] In order to avoid interfering with the assembly of the third detection component 5, an assembly groove 802 is further provided on the top cover 82 to accommodate the third detection component 5; the assembly groove 802 is appropriately opened larger to avoid interfering with the rotation of the cover shell 8, so that the cover shell 8 can normally cover the detection hole 1402;

[0121] Among them, when the shell 83 is set, it directly blocks the accommodating groove 1401 to avoid air leakage, so that the gas can be output through the detection hole 1402, so there is no need to set up an additional sealing structure to seal the accommodating groove 1401; at the same time, appropriate sealing measures can be set between the shell 83 and the circumferential surface of the anvil 14, such as a high-temperature resistant sealing ring, to avoid air leakage in the gap.

[0122] like Figure 2 and Figure 7 and Fig.13 As shown, the cover 8 reciprocates along the axis of the anvil 14 to selectively make the through slot 801 correspond to the detection hole 1402; when the cover 8 blocks the detection hole 1402, the through slot 801 corresponds to or does not correspond to the purge hole 201;

[0123] As in the above structure, due to the interference of the third detection assembly 5, the cover 8 cannot rotate and can only cover or open the detection hole 1402 in a reciprocating swinging manner;

[0124] With respect to this structure, when the cover shell 8 blocks the detection hole 1402, the purge hole 201 of the mold 2 is set to correspond to the through groove 801. At this time, the through groove 801 does not correspond to the detection hole 1402, but corresponds to the end face of the anvil 14. Through the continuous purge of the purge hole 201, this part of the end face of the anvil 14 will not accumulate the oxide layer that falls off the embryo. In this way, when the cover shell 8 is swung to make the through groove 801 correspond to the detection hole 1402, the detached oxide layer will not be pushed into the detection hole 1402, thereby ensuring that the detection can be carried out normally to ensure the stability of the application.

[0125] In this structure, the connecting section 14034 may not be provided; preferably, the connecting section 14034 is provided for purging and cooling the laser emitter 41 and the temperature sensor 43 .

[0126] The material blank forging control method of the present invention uses the above-mentioned die steel blank forging detection control structure, and comprises the following steps:

[0127] S1, setting a reference height of the power hammer 13, and detecting a height fluctuation variable of the power hammer 13 through the first detection component 3;

[0128] S2, detecting the size of the mold 2 through the third detection component 5;

[0129] S3, according to the size information of the mold 2, determine the corresponding blank processing steps;

[0130] S4, driving the power hammer 13 to forge the blank through the cylinder 12, and adjusting the opening of the rotary valve according to the height fluctuation variable of the power hammer 13 to control the stroke of the power hammer 13;

[0131] S5, after the third detection component 5 detects that the size of the blank is qualified, the forging is stopped;

[0132] Specifically, the power hammer 13 is controlled by the gas path structure and will continue to float up and down when in standby mode as the gas flows. This part is the height fluctuation variable of the power hammer 13, so the reference height of the power hammer 13 should be set; if the height variable is between h1 and h2, the reference height is h3, where h2>h1>h3;

[0133] When the power hammer 13 is on standby and fluctuates up and down, since the reference height h3 is determined, the height of the power hammer 13 above the reference height h3 and between h1 and h2 can be monitored in real time. When forging, if it is detected that the power hammer 13 is below the reference height h3, it means that the power hammer 13 has been forged, and the total stroke of the power hammer 13 forging this time can be known. In this way, the stroke of the power hammer 13 is effectively detected.

[0134] During forging, the opening of the air circuit rotary valve is adjusted in real time according to the different heights of the power hammer 13 between h1 and h2. When the power hammer 13 is at a greater height between h1 and h2, the air circuit pressure during forging is reduced, and vice versa. Although the power hammer 13 still fluctuates, the influence of the height fluctuation of the power hammer 13 is eliminated, thereby effectively controlling the forging force.

[0135] At the same time, the higher the height of the mold 2, the smaller the stroke of the power hammer 13, and the air pressure of the air circuit can be set to be larger to increase the impact force; if the height of the mold 2 is lower, the stroke of the power hammer 13 is larger, and it has greater potential energy, and the air pressure of the air circuit can be appropriately reduced, so that the impact force is more moderate;

[0136] Specifically, after the model of the mold 2 is detected, the total height of the mold 2 and the blank is simultaneously known, so as to achieve adaptive adjustment of forging to ensure processing accuracy.

[0137] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
