The present invention comprehensively applies stamping technology to a circular universal lock core component, including: a lock core body, a lock core, marbles, springs, anti-drilling plates, a constant torque structure, a lock core function output connecting piece, and a key. Among them: The lock core body is composed of various flat or undulating formed laminations, a lock core body lamination positioning connecting piece, and a housing. The formed laminations include an outer end piece, a cavity piece, an intermediate piece, an inner end piece, or an outer end piece, a cavity piece, and an inner end piece. The external shape of the formed laminations corresponds to the cavity of the lock core body housing and the tenon of the lock core body lamination positioning connecting piece. The anti-drilling plate is arranged between the key through hole of the lock core body housing and the outer end piece. The central through hole corresponds to the key insertion end, the outer diameter corresponds to the key through hole of the lock core body housing and the inner diameter of the flanging vertical edge of the outer end piece, and the thickness corresponds to the height of the flanging vertical edge. The central notch and cavity of the outer end piece correspond to the key insertion end, the floating vane marbles, the deflecting vane marbles, the axial vane marbles, and the cavity of the outer end face of the lock core. The key rotation hole diameter is set according to the key being able to withstand a torque greater than 3 N·m without deformation + a safety factor to prevent the lock core from being damaged by violent twisting with a non-original key or other tools. The cavity piece is arranged between the front end piece and the intermediate piece or the inner end piece. The inner diameter of the flanging cavity corresponds to the outer diameter of the lock core. The radial notch or through hole corresponds to the marbles, the marble springs, and the special-shaped leaf springs. The number and cumulative length of the cavity pieces correspond to the length of the lock core and the number of marble groups. The internal cavity, notch, and through hole of the intermediate piece correspond to the floating vane marbles, the deflecting vane marbles, the axial vane marbles, the inner end face of the lock core, and the lock core function output connecting piece. The central cavity, notch, and through hole of the inner end piece or the additional intermediate piece correspond to the floating vane, the deflecting vane, the axial vane, the inner end face of the lock core, and the lock core function output connecting piece. The lock core body lamination positioning connecting piece is in the shape of a thin strip. The tenons on both sides correspond to the thickness of the lock core body lamination material. The key insertion hole at the center of the outer end face of the circular housing corresponds to the rotation diameter of the key insertion stop and the outer diameter of the anti-drilling plate. The internal cavity corresponds to the outer shape of the lock core body laminations. The length corresponds to the cumulative thickness of various laminations. The inner diameter of the flanging at the open end corresponds to the exposed end face of the inner end piece. The lock core includes two structures: a circular tube hollow lock core + a lock core outer end piece + a lock core inner end piece, or a partially hollow lock core + a lock core outer end piece. The outer edge tenon of the lock core outer end piece corresponds to the outer end tenon of the circular tube hollow lock core or the partially hollow lock core. The central cavity notch corresponds to the outer end edge of the floating vane marbles, the deflecting vane marbles, the axial vane marbles, the key insertion end, and the cavity of the outer end piece of the lock core body. The outer diameter notch of the circular tube hollow lock core corresponds to the outer edges of the floating vane marbles, the deflecting vane marbles, the axial vane marbles, and the special-shaped leaf spring. The inner end tenon corresponds to the outer edge tenon of the lock core inner end piece. The cavity and recess of the lock core inner end piece correspond to the inner end edge of the floating vane marbles, the inner end edge of the deflecting vane marbles, the inner end edge of the axial vane marbles, the transition vane marbles, the front end of the key, the cavity of the intermediate piece, and the connecting end of the lock core function connecting piece. The storage recess of the transition vane is offset by a certain angle from the cavities of other vanes.The mortise on the outer end face of the partially hollow lock core corresponds to the mortise on the outer end piece of the lock core. The outer diameter notch or round hole and blind hole correspond to the axial blade or deflecting blade driver, radial blade driver or round driver, transition round driver, and driver spring. The blind hole of the transition round driver is offset by a certain angle from other blade notches or round driver holes. The inner end cavity and recess correspond to the inner end edge of the deflecting or floating blade driver, the inner end edge of the axial blade driver, the transition blade driver, the front end of the key, the cavity of the intermediate piece, and the connecting end of the lock core functional connector. The storage recess of the transition blade is offset by a certain angle from other blade notches or round driver holes. The other end of the lock core functional connector is connected to the controlled end. The drivers include blade drivers, round drivers, and transition drivers. The blade drivers are classified according to their movement characteristics into floating blade drivers, deflecting blade drivers, axial blade drivers, and radial blade drivers. The floating blade driver, deflecting blade driver, and axial blade driver are in the shape of thin, irregular polygonal rectangles. The h-shaped tongue cut in the middle towards the inner end edge corresponds to the inner diameter of the driver spring. The outer end edge corresponds to the outer end piece of the lock core body and the cavity of the outer end piece of the lock core. The edge towards the outer diameter of the lock core corresponds to the radial notch of the lock core, the cavity notch of the lock core body piece, and the special-shaped leaf spring. The edge towards the inner end face of the lock core corresponds to the cavity of the inner end face of the lock core, the cavity of the inner end piece or the intermediate piece. The stepped shaft diameter with a two-way step towards the key edge corresponds to the corresponding key tooth rib pattern. The outer inclined edge on the outer end edge of the deflecting blade causes the deflecting driver to make a deflecting radial movement to lock the lock core, and the middle inclined edge towards the radial edge of the lock core forces the driver to move inwards to release the lock of the lock core. The radial blade consists of a blade group composed of 1 leaf with a spring on each of the left and right sides + 1 leaf without a spring. The leaf without a spring is in the shape of a parallel truncated circular thin sheet with an open end on one side. The two ends of the parallel truncated circle correspond to the cavity notches. The two ends of the arc correspond to the diameter of the lock core. The width and shape of the open end correspond to the key and the blade stroke. The position of the middle protruding tongue corresponds to the step of the key snake-shaped groove. The non-open end edge corresponds to the outer diameter of the blade spring. The outer shape of the parallel truncated circle of the leaf with a spring is the same as that of the leaf without a spring. The width and shape of the open end correspond to the key shape, tooth pattern step, and blade stroke. The outer arc edges of the left and right protruding tongues on the non-open end edge correspond to the diameter of the lock core. The inner open straight edge corresponds to the outer diameter and both ends of the driver spring. The shape and specifications of the round driver are the same as those of the existing round driver lock core. The transition driver of the round driver is a steel ball with a driver diameter equal to the step. The transition blade of the floating blade, deflecting blade, and axial blade is a rectangular thin sheet with a thickness equal to the axial step. The above drivers are distributed in a one-word, cross, or T-shaped form with the center of the lock core as the origin. The driver combination can form different combinations of a floating blade or deflecting blade + axial blade to form a general or special lock core, a radial blade + axial blade general or special lock core, and a round driver + deflecting blade or axial blade general or special lock core.The spring includes a ball spring, a special-shaped leaf spring, other functional springs or a snap ring. The ball spring is a micro compression spring, and the special-shaped leaf spring is a special leaf spring for floating blades. The middle part is wavy, and the two ends are flat wire leaf springs in the shape of a straight line. The two ends of the leaf spring correspond to the outer end piece, the middle piece or the inner end piece respectively. The wavy section in the middle is normally located between the notch of the lock core and the rotating surface of the notch of the cavity piece. It can only fully enter one side of the groove of the cavity piece under the action of the original key and the floating blade to perform the opening and closing operation of the lock core. The key includes a transition key, a regular key and a master key. The types, distributions, tooth patterns and quantities of the tooth ribs at the front end of the key correspond to the types, distributions, tooth patterns and quantities of the balls, as well as the step difference. The symmetric notch at the middle part near the anti-drilling piece stop is the key torque limiting notch. This notch is set by multiplying the safety factor to ensure that the key has no obvious deformation and can be used normally after being subjected to a torque of 3 N·m. The notch corresponds to the key rotation hole diameter of the outer end piece. The axial tooth pattern length of the leaf ball transition key is one transition blade thickness longer than that of the regular key. The tooth pattern of the round ball transition key tooth rib is one step deeper than that of the regular key round ball tooth rib. Insert the original regular key to open the lock core. The transition ball enters the concave cavity at the inner end face of the lock core or the radial blind hole of the lock core under the action of the spring, and the transition key is scrapped. The master key, according to the principle of arranging the key key amount and functional requirements, includes: a base plate, a snap ring, replaceable axial or variable-direction ball step-shaped tooth ribs, replaceable inclined tooth ribs, a sliding collar, a spring. The tooth pattern and step difference of the tooth at the key end of the key base plate, the replaceable tooth rib tooth pattern correspond to the leaf ball and the round ball. The notch or through hole in the middle part facing the outer end corresponds to the shape of the positioning side of the replaceable tooth rib. The rest is basically the same as the regular key. The snap ring is a wire snap ring, and the wire diameter corresponds to the inner snap ring groove at the outer end of the sliding collar. The internal cross sliding notches of the sliding collar correspond to the base plate and the replaceable tooth ribs respectively. The inner cavity at the key handle end corresponds to the outer diameter of the spring. The two ends of the spring correspond to the sliding collar and the handle end of the key base plate respectively. The lock core key of the floating blade ball or variable-direction blade ball consists of a front and back surface piece + a base plate to form a handle part with a partially hollow one-word key. The flanging holes in the middle of the front and back surface pieces correspond to the through holes of the base plate. The flanging holes of the front and back surface pieces and the front end of the key are fixed simultaneously by spot welding with the front end of the base plate. The tooth pattern of the radial blade ball lock core key is distributed in a T shape; the tooth pattern of the round ball lock core key is distributed in a cross shape.;

Among them: The lock core assembly adds a locking piece and a locking piece spring compared with the general lock core, and can cancel the floating blade, the deflecting blade, the middle cut tongue of the axial blade and the ball spring (this structural combination can also be used for a circular general lock core). By adjusting the number of cavity pieces, different length specifications are met. The length-adjusting cavity piece is arranged between the middle piece and the inner end piece, and its structure and shape are the same as those of other cavity pieces; The locking piece is arranged in the length-adjusting cavity piece, and its outer shape corresponds to the inner cavity of the cavity piece. The locking protrusion corresponds to the cavity of the middle piece and the inner end face of the lock core, the floating blade or the deflecting blade, the axial blade towards the inner end, and the transition blade. The internal through hole corresponds to the rotating outer diameter of the lock core function output connecting piece. The reverse side edge of the locking protrusion corresponds to the locking piece spring; The flanging through hole of the inner end piece corresponds to the radial support outer diameter of the lock core function output connecting piece, the flanging outer diameter corresponds to the rotating inner diameter of the fork or gear, and the flanging end face corresponds to the axial positioning partition rib of the rotating inner diameter of the fork or gear; The lock core body laminated positioning connecting piece is arranged on both sides of the parallel side edges of the formed laminate and at the circular top of the symmetric line of the gourd shape, and the rest of the structure is the same as that of the general lock core; The indoor and outdoor lock core body connecting piece includes an indoor and outdoor lock core body U-shaped connecting piece + a U-shaped reinforcing connecting piece. The U-shaped convex and concave tenon of the connecting piece corresponds to the thickness and spacing of the indoor and outdoor lock core laminates. The left and right connecting and fixing cut tongues in the middle correspond to the U-shaped reinforcing connecting piece. The left and right end faces of the U-shaped reinforcing connecting piece correspond to the flanging end faces of the left and right inner end pieces and the left and right cut tongues in the middle of the lock core body connecting piece. The material thickness of the lock core body connecting piece is set according to 2 times the thickness of the connecting piece + 2 times the thickness of the reinforcing connecting piece + 2 times the thickness of the outer shell is greater than or equal to 5 times the m5 pitch, and there is no thread slipping or tripping phenomenon after the screw hole bears a static tension of 3000N; The outer shell includes an outer shell + an outdoor lock core assembly surface piece + an indoor lock core assembly surface piece. The key insertion hole in the middle of the outdoor or indoor lock core surface piece corresponds to the rotating diameter of the key insertion stop and the outer diameter of the anti-drilling piece. The indoor or outdoor lock core surface piece is firmly spot-welded to the outer end piece of the indoor or outdoor lock core with the anti-drilling piece installed, and it is ensured that the anti-drilling piece can rotate flexibly. The outer shape of the outdoor lock core surface piece corresponds to the outer shape of the outer shell, and the outer shape of the indoor lock core surface piece corresponds to the inner cavity of the outer shell. The inner cavity of the gourd-shaped outer shell corresponds to the outer shape of the formed laminate, the U-shaped indoor and outdoor lock core body connecting piece, and the outer shape of the fork. The middle parallel notch corresponds to the fork or gear. The indoor and outdoor lock core length corresponds to the lock core specification, the cumulative thickness of various laminates, and the indoor and outdoor lock core body connecting piece;The lock core function output connecting piece is a hollow octagonal sleeve. Its shape at the lock core end corresponds to the inner end face cavity of the lock core, the inner end of the floating blade or the deflecting blade, the inner end of the axial blade, and the front end of the key. The other end corresponds to the connecting cavity of the fork or gear. The middle flanging supports that the rotating outer diameter corresponds to the inner diameter of the flanging of the inner end piece. The axial position of the flanging support corresponds to the separation stroke of the connection of the fork or gear and the length of the flanging cavity of the inner end piece. When the lock core is in the locked state, the indoor and outdoor lock core function output connecting pieces are simultaneously connected to the fork. The lock core pushes the lock core function output connecting piece through the front end of the key to disconnect the other lock core function output connecting piece; The fork is composed of a cavity ring and left and right fork connecting pieces. The cavity ring is an elastic open ring. The shape of its fork part is the same as that of the existing fork, and the rest is appropriately adjusted with reference to the shape of the inner end piece and the outer shell cavity. Its opening is located at the top of the circular part of the left-right symmetry axis of the radial outer shape. The connecting tenon holes on both sides of the left-right axial symmetry line correspond to the tenon mouths of the left and right fork connecting pieces. The middle cavity of the left and right fork connecting pieces corresponds to the lock core function connecting piece, and the surrounding tenon mouths correspond to the tenon holes of the cavity ring; The locking piece spring is a small compression spring. The inner diameter of the spring corresponds to the rotating outer diameter of the lock core function output connecting piece, and the two ends respectively correspond to the reverse side of the locking protrusion of the locking piece or the end face of the flanging support of the lock core function output connecting piece; The lock core is welded at the middle piece of the outdoor lock core + the left and right cavity pieces with a pneumatic spot welder for transmission, or the encapsulation and positioning are completed by compressing the hollow parts on both sides of this part. After the encapsulation and fixation are completed, the m5 screw hole is machined.;

[0006] 3 The present invention comprehensively applies the stamping process to the European standard insert core indoor door lock core components, including an outdoor door lock core assembly, an indoor door lock core assembly, an indoor and outdoor lock core body connecting piece, a lock core function output connecting piece, a fork, and a key. Among them: Except that a fork detachment connecting spring is added to the cavity at the connecting end of the lock core function output connecting piece and the fork in the outdoor lock core assembly, the rest is the same as the European standard insert core outdoor door lock core; The outer diameter of the fork detachment connecting spring corresponds to the inner cavity of the lock core function output connecting piece, and the two ends respectively correspond to the partition wall of the inner cavity of the lock core function output connecting piece or the inner end face of the indoor lock core shaft. The elastic force of the fork detachment connecting spring is greater than that of the locking piece spring, so that the lock core function output connecting piece and the fork are in a detached connection state and can only be connected to the fork under the push of the key; The fork connecting piece connecting the fork to the indoor lock core is welded to the indoor lock core shaft as a whole, and the rest is the same as the fork of the European standard insert core outdoor door lock core; The indoor lock core assembly includes an indoor lock core shaft, a handle, a surface piece, an indoor lock core shaft support piece, an outer end piece, a lock core body laminated positioning connecting piece, and an inner end piece. Among them, the surface piece, the outer end piece, the inner end piece, and the lock core body laminated positioning connecting piece are the same as those of the outdoor lock core; The inner through hole of the indoor lock core shaft support piece corresponds to the indoor lock core shaft, and the rest is the same as the anti-drill piece; The indoor lock core shaft is a cold-drawn round bar, and its outer diameter corresponds to the inner diameter of the lock core shaft support piece, the inner diameter of the connecting end of the handle, and the inner diameter of the center hole of the fork connecting piece, and is welded to the fork connecting piece; The handle is a hollow cylindrical handle, and the reduced inner diameter of the connecting end with the indoor lock core shaft corresponds to the lock core shaft. The connection between the hollow handle and the indoor lock core shaft is fixed by flattening the connecting end of the handle after completing the lock core encapsulation positioning; For the lock core encapsulation positioning, the processing of the M5 screw hole is the same as that of the outdoor lock core.

[0007] 4 A lock core service system process of the present invention, including a floating vane tumbler or a deflecting vane tumbler lock core, a radial vane tumbler lock core, a round tumbler lock core, and a lock core component that comprehensively applies the stamping process, includes a coding piece, a master key, and a product after-sales service system. Among them: The coding piece is a bar code card printed with the product manufacturer, type, key secret, quality grade, and relevant original information represented by digital symbols, and the information content is covered by a paint that can be scraped off; The service system process has functions such as product information registration, after-sales service application, after-sales service customer legitimacy certification, product after-sales service allocation, and product after-sales service information registration through the Internet and telephone. The end customer registers and registers key information with the product after-sales service terminal using the code obtained by scraping the card, including bar code, customer contact information, and brief information about the location. When the customer needs to purchase additional keys or provide services, the customer can choose to let the after-sales service personnel deliver the additional keys or the master key to near the residence, solve the problem by himself, or permit the after-sales service personnel to solve the problem, and then replace the lock core.

[0008] The aforementioned demonstration application plan for comprehensively applying the stamping structure lock core component adds deflecting or axial vane pins compared with the existing publicly disclosed lock core plans. Both the deflecting vane pins and the floating vane pins use long radial edges to lock the lock core, and have a larger radial anti-shear area than traditional radial vane pins or round pins. Therefore, the lock cores with deflecting vane pins or floating vane pins have stronger anti-twisting and violent destruction resistance capabilities than the lock cores with radial vane pins and round pins; according to the setting of a ￠13*20 round universal lock core, 4 groups of floating vane pins with pin springs + 2 axial vane pins are set. The floating vane pins are calculated according to the rule that the step difference is greater than or equal to 0.5 mm, and 102 single-step shaft diameter bidirectional step differences can be set. The axial vane pins can be set with 37 step differences calculated. The key secret key = 102*102*102*102*37*37 = 148.1 billion combinations; the highest reported key amount of the existing radial vane lock core is 16 million. According to the ￠13*20 round universal vane lock core, adding one deflecting vane pin and calculating with 33 axial step differences for the deflecting vane pin, the key amount of its key can reach 16 million * 33 = 528 million combinations; according to the existing ￠13*20 round universal round pin lock core, at most 5 groups of ￠3 diameter single-row round pins can be set. The round pins are calculated with a maximum of 6 step differences. The key amount = 6*6*6*6*6 = 7776 combinations. After deducting the non-existent false combinations and the combinations with too simple combination arrangements such as 12345 or 11111, the actual available key amount is about 6000. After adding 3 deflecting vane pins and setting 33 axial step differences for the deflecting vane pins, the key amount = 6000*33*33*33 = 215 million combinations; according to the ￠13*20 European standard mortise indoor door lock core, calculated according to the combination of 4 groups of floating vane pins without pin springs + 2 axial vane pins, the floating vane pins without pin springs can be set with 35 axial step differences and 4 radial step differences, that is: 35*4 = 140 single-step shaft diameter bidirectional step differences. The axial vane pins are set with 37 step differences calculated. The key amount = 140*140*140*140*37*37 = 525.9 billion combinations; calculated according to the combination of 4 groups of deflecting vane pins + 2 axial vane pins for the lock core of the same specification, the deflecting vane pins can be set with 37 axial step differences and 1 radial step difference, and the axial vane pins are set with 37 step differences calculated. The key amount = 37*37*37*37*37*37 = 25.6.5 billion combinations. The above data shows that the aforementioned solution can significantly increase the key amount of the lock core, reduce the mutual opening rate of products, and improve the anti-technical opening performance of the lock core at the same time. Since the key and the pin are matched in the hollow or partially hollow part of the lock core, there is no supporting point for the tin foil to exert force when using the tin foil for technical opening, so it can prevent the technical opening of the hollow or partially hollow lock core with tin foil. The continuous step-forming production process is a high-efficiency, low-cost and economic precision processing technology widely used in the machinery manufacturing industry. By changing various lock core functional parts into stamping structures, the economic precision processing cost of the lock core parts can be significantly reduced. The undulating forming structure can also greatly reduce the material consumption. The price difference between the stainless steel material and the copper material is 30-50%, which can further significantly reduce the material procurement cost. The stainless steel lock core can pass the detection requirement that the melting temperature of all the hardware fittings of the fire door is not less than 950 degrees Celsius. The chemical surface treatment process for producing zinc, aluminum, and copper alloy lock cores pollutes the environment. There is no need to carry out the chemical surface treatment process for producing stainless steel lock cores, and it has a more environmentally friendly competitive advantage in the production process flow than producing zinc, aluminum, and copper alloy lock cores, and can achieve the expected goal of reducing the product production cost on the premise of improving the product performance. The lock core service system process delivers the key information parameters of the lock core to the customer for self-preservation in the form of scraping codes, which can ensure the customer's rights and interests to the greatest extent. At the same time, the maintenance service personnel can also provide fast and high-quality services for the customer. Description of the Drawings

Each floating vane pin is provided with 102 non-repeating encodings in both axial directions of the shaft diameter. The 2 deflecting pins are provided with 37 axial step differences. The non-repeating key combination of the key is more than 148.1 billion kinds. The procurement quantity of the lock copper for the 5-piece key round pin lock core with a diameter of 28*25 specification is about 300 grams. The procurement quantity of the stainless steel material for the 5-piece key lock core with the same specification floating vane pin is calculated according to the stamping process overlap allowance: about 150 grams.

The non-pin spring axial vane pin has 37 step differences. The key key quantity = 140 * 140 * 140 * 140 * 37 * 37 = 525.9 billion combinations. Compared with the highest key quantity of 16 million of the existing radial vane pin lock core = 525.9 billion / 16 million = 32,869.69 million times. Compared with the actual available key quantity of 6,000 of the single-row 5-group round pin lock core = 525.9 billion / 6,000 = 87,652 million times.
