Metal parts stamping system

Abstract

The present invention provides a metal part stamping system; when the winding machine pulls the steel strip out from the unwinder and winds it up, the steel strip drives the rack on it to move. At this time, the rack pushes the antenna to drive the counterweight block to move up and down. At the same time, since the tooth peaks and tooth valleys of the rack are irregular in height and the rack extends continuously to the two ends of the steel strip, the distance sensing component continuously collects the distance information between it and the counterweight block and converts it into a wavy line. The peaks and troughs of the wavy line are also irregular, that is, the position of each part of the steel strip can be determined by the wavy line change pattern, peak and trough values, and the numbering information of each part of the steel strip can be obtained to register the information of the part to be processed on the steel strip, so that when the part to be stamped is processed, there is no need to scan the code through a mechanical mechanism or manual operation, thereby reducing processing costs, reducing equipment manufacturing costs, simplifying processing steps and improving safety; the present invention belongs to the technical field of stamping dies.

Description

Technical Field

[0001] The invention belongs to the technical field of stamping dies, and in particular relates to a metal part stamping system. Background Art

[0002] A metal stamping system is a production line used to manufacture and process parts for the automotive, home appliance, electronics, and aerospace industries. Its primary process involves loading raw metal into the mold cavity and then driving the mold open and close to press the raw metal into a specific shape. During the stamping process, the punch in the stamping station must withstand extreme pressure, so the punch is generally fixed and immovable within the stamping die. Furthermore, due to the physical properties of metal materials, their deformation limits, and the complexity of the final product's part structure (for example, a certain part requires bending in multiple directions), the raw metal needs to be sequentially transported to different stamping stations for multiple stamping operations.

[0003] In conventional production lines, product information is generally registered as it passes through each workstation to achieve quality control, process optimization, and process traceability. Traditionally, product information registration is performed by scanning a barcode attached to the product, reading the product's identity information, and then registering the product.

[0004] However, because the stamping station (i.e., the stamping die) must withstand extremely high pressure during the stamping process, it is inconvenient to place the barcode scanner inside the stamping station (i.e., the stamping die). The pressure from the stamping die can also damage the information code. Using manual or other mechanical means to scan the code before stamping increases equipment manufacturing costs, labor costs, and the process becomes cumbersome. Furthermore, the stamping process generates a large amount of metal debris, which can easily interfere with the scanner's operation and scratch it. Summary of the Invention

[0005] The purpose of the present invention is to provide a metal part stamping system to solve the technical problems described in the background art.

[0006] The metal part stamping system comprises:

[0007] Unwinder, which contains a steel strip for stamping. The bottom of the steel strip is engraved with irregular and uninterrupted racks.

[0008] Winder, the head end of the steel strip is connected to the winder;

[0009] There are several stamping stations, each of which is equipped with a stamping cavity slot, a rocker and a stamping device. When the winder pulls the steel strip out of the unwinder and winds it up, the part of the steel strip to be stamped passes through all the stamping cavity slots one by one. The bottom wall of the stamping cavity slot is provided with a code reading movable slot, and one end of the rocker is provided with a tentacles that are located in the code reading movable slot and move up and down. The other end of the rocker is provided with a counterweight block so that the tentacles are in close contact with the rack. A distance sensing component is provided under the counterweight block, and the rack pushes the tentacles to drive the counterweight block to move up and down. The distance sensing component is used to continuously collect the distance information between it and the counterweight block and convert it into a wave line, and at the same time is used to collect each peak and trough value of the wave line to combine into a code, so as to register information of each part of the steel strip according to the code, and the stamping device is used to stamp the part to be stamped that passes through the stamping cavity slot.

[0010] Based on the above technical solution, the present invention can achieve the following beneficial effects:

[0011] 1. When the metal raw materials are sequentially transported to different stamping stations for multiple stamping, since the metal raw materials to be processed are on the steel strip, and the steel strip passes through all the stamping cavities one by one, it is only necessary to use the reel to pull the steel strip out of the unwinder and rewind it, so that the metal raw materials to be processed can be transferred one by one and in order to the stamping cavities of each stamping station, without the need to use manual labor or handling machinery to transport these metal raw materials to be processed to each stamping station one by one, thereby improving processing efficiency and reducing processing costs and equipment manufacturing costs;

[0012] 2. When the winder pulls the steel strip out of the unwinder and winds it up, the rack on the steel strip also moves. At this time, the rack pushes the tentacles to drive the counterweight to move up and down. At the same time, since the tooth peaks and tooth valleys of the rack are irregular in height and the rack extends continuously to both ends of the steel strip, the distance sensing component continuously collects the distance information between it and the counterweight and converts it into a wavy line. The peaks and troughs of the wavy line are also irregular, that is, the position of each part of the steel strip can be determined by the wave line change pattern, peak and trough values, and the numbering information (identity information) of each part of the steel strip can be obtained to register the information of the part to be processed on the steel strip. Therefore, when processing the part to be stamped, there is no need to scan the code through mechanical mechanism or manual operation, so as to reduce processing costs, reduce equipment manufacturing costs, reduce labor costs, simplify processing steps and improve processing safety.

[0013] 3. Compared with traditional information recognition systems (barcode scanners or visual recognition systems), the opening and closing of the mold on the stamping station will not cause significant damage to the hardware structure related to information recognition;

[0014] 4. Compared with traditional information recognition systems (i.e., barcode scanners or visual recognition systems), since the rack is located on the bottom surface of the steel belt, the metal debris generated by the stamping process will fall due to gravity. At the same time, since the tentacles are in close contact with the rack, if metal debris appears on the rack, the metal debris will also be pushed away by the tentacles, thereby reducing the possibility of metal debris interfering with the information recognition process.

[0015] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0016] In some embodiments, a limiting groove is provided on the side wall of the stamping cavity groove. When the steel belt passes through the stamping cavity groove, the side edge of the steel belt is located in the limiting groove. The top wall of the limiting groove is provided with a code reading pulley for contacting the top wall of the side edge of the steel belt. The code reading movable groove is located on the bottom wall of the limiting groove, and the antenna is on the same center line as the code reading pulley.

[0017] Based on the above technical solution, when the feeler slides on the rack, the steel belt is limited by the code reading pulley, so that the rack pushes the feeler to more stably drive the counterweight block to move up and down.

[0018] In some embodiments, the counterweight is equipped with a magnet, and the distance sensing component is a Hall IC for sensing the magnet, so that when the counterweight drives the magnet closer to or away from the Hall IC, the Hall IC obtains a wavy line by continuously recording and counting the changes in the magnetic field.

[0019] Based on the above technical solution, compared with traditional infrared ranging, it can be unaffected by dust, metal debris, smoke and oil pollution, thereby improving the stability and efficiency of ranging.

[0020] In some embodiments, the unwinder, the rewinder, and the stamping station are all provided with a lifting mechanism, and after the stamping portion completes stamping in the stamping cavity, the lifting mechanism is used to lift the steel strip and move it away from the stamping cavity;

[0021] The stamping station is equipped with a floating block that can be raised and lowered. The code reading movable slot, rocker, distance sensing component and limit slot are all arranged on the floating block. When the steel belt is lifted or lowered, the steel belt drives the code reading movable slot, rocker, distance sensing component and limit slot to rise and fall synchronously to offset the slope section added to the wavy line when the steel belt is lifted or lowered.

[0022] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0023] 1. After the part to be stamped is stamped in the stamping cavity, the lifting mechanism lifts the steel strip and moves it away from the stamping cavity. This prevents the steel strip (including the part to be stamped) from being damaged by friction with the stamping cavity as the steel strip moves into or out of each stamping station one by one.

[0024] 2. When the lifting mechanism lifts the steel strip and moves it away from the stamping cavity slot, the steel strip drives the code reading movable slot, rocker, distance sensing component and limit slot to rise synchronously, thereby offsetting the slope section added to the wave line when the steel strip is lifted, thereby avoiding interference with the peak and trough values ​​of the wave line when the steel strip is lifted or lowered by the lifting mechanism.

[0025] In some embodiments, the unwinder, the rewinder, and the stamping station are all provided with a lifting mechanism. After the stamping portion completes stamping in the stamping cavity, the lifting mechanism is used to lift the steel strip and move it away from the stamping cavity. The lifting mechanism is provided with a lifting stroke sensor. The lifting stroke sensor is used to record the lifting stroke when the steel strip is lifted or lowered, thereby offsetting the slope section added to the wavy line when the steel strip is lifted or lowered.

[0026] Based on the above technical solution, the present invention further achieves the following beneficial effects:

[0027] 1. After the part to be stamped is stamped in the stamping cavity, the lifting mechanism lifts the steel strip and moves it away from the stamping cavity, thereby preventing the steel strip from being damaged by friction with the stamping cavity during the process of the part to be stamped moving away from or into the stamping cavity;

[0028] 2. By setting the lifting stroke sensor, the lifting stroke of the steel belt is recorded when the steel belt lifting mechanism is lifted or lowered to offset the slope section added to the wave line, thereby avoiding interference with the peak and trough values ​​of the wave line.

[0029] In some embodiments, the metal part stamping system further includes:

[0030] The encoding station is located between the unwinder and the first punching station. The encoding station is provided with an engraving slot and a screw module. The steel strip passes through the engraving slot. The bottom wall of the engraving slot is provided with an engraving movable slot. The screw module drives an engraving knife that rises and falls in the engraving movable slot and contacts the bottom wall of the steel strip.

[0031] Speed ​​sensor: The speed sensor is used to sense the moving speed of the steel strip.

[0032] Based on the above technical solution, when the winder pulls the steel strip out of the unwinder and winds it up, the screw module drives the engraving knife close to or away from the top wall of the steel strip according to the moving speed of the steel strip, thereby engraving irregular and uninterrupted racks on the bottom surface of the steel strip to achieve coding of various parts of the steel strip.

[0033] In some embodiments, the top wall of the engraving slot is provided with an engraving pulley for contacting the top wall of the steel strip, and the engraving pulley and the engraving knife are on the same center line;

[0034] Based on the above technical solution, when the engraving tool contacts the steel belt, the steel belt is limited by the engraving pulley, so that the engraving tool can engrave the rack on the steel belt more stably.

[0035] In some embodiments, the engraving knife is provided with a sensing piece, and the speed sensor includes another distance sensor and a timer;

[0036] When the screw module drives the engraving tool to approach or move away from the top wall of the steel strip, another distance sensor continuously collects the distance information between it and the sensor plate and converts it into a reference wave line. The timer is used to calculate the time required for the distance sensor component to obtain the coincidence of the wave line with the reference wave line, thereby determining the speed of the steel strip;

[0037] The timer is also used to calculate the duration of a certain peak and trough value of the wave line or the reference wave line to determine whether the steel belt has stopped moving.

[0038] In some embodiments, the metal part stamping system further includes a knock-down station, located between the coiler and the nearest stamping station, and configured to knock the stamped product off the steel strip.

[0039] Based on the above technical solution, after the part to be punched on the steel strip is punched into the product, the punched product on the steel strip is knocked off the steel strip through the knocking station, thereby realizing product unloading. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] In order to make the objectives, technical solutions and advantages of the present invention more clear, the following description is given with reference to the accompanying drawings.

[0048] like Figures 1 to 4 As shown, this specific embodiment provides a metal part stamping system, which includes:

[0049] An unwinder 2, wherein a steel strip 1 for stamping is wound inside the unwinder 2, and a rack 11 with irregular and uninterrupted heights is engraved on the bottom surface of the steel strip 1;

[0050] Winder 3, the head end of the steel strip 1 is connected to the winder 3;

[0051] There are several stamping stations 4, each of which is provided with a stamping cavity slot 41, a rocker 51 and a stamping device 42. When the reel 3 pulls the steel strip 1 out of the unwinder 2 and rewinds it, the part of the steel strip 1 to be stamped passes through all the stamping cavity slots 41 one by one. The bottom wall of the stamping cavity slot 41 is provided with a code reading movable slot 5. One end of the rocker 51 is provided with a feeler 52 which is located in the code reading movable slot 5 and moves up and down. The other end of the rocker 51 is provided with a counterweight 53 so that the feeler 52 is in close contact with the rack 11. A distance sensing component 54 is provided below the counterweight 53. The distance sensing component 54 can be a traditional infrared distance sensor. The rack 11 pushes the feeler 52 to drive the counterweight 53 to move up and down. The distance sensing component 54 is used to continuously collect the distance information between it and the counterweight 53 and convert it into a wavy line, such as Figure 4 As shown, it is used to collect each peak and trough value of the wave line to combine into a code, so as to register information of each part of the steel strip 1 according to the code, and the stamping device 42 is used to stamp the part to be stamped through the stamping cavity groove 41.

[0052] When the metal raw materials are transported to different stamping stations 4 in sequence for multiple stamping, since the metal raw materials to be processed are on the steel strip 1 and the steel strip 1 passes through all the stamping cavity grooves 41 one by one, it is only necessary to use the winder 3 to pull the steel strip 1 out of the unwinder 2 and wind it up, so that the metal raw materials to be processed can be transferred one by one and in order to the stamping cavity grooves of each stamping station 4, without the need to use manual labor or handling machinery to transport these metal raw materials to be processed to each stamping station 4 one by one, thereby improving processing efficiency, reducing processing costs and equipment manufacturing costs.

[0053] As the winder 3 pulls the steel strip 1 out of the unwinder 2 and winds it up, the rack 11 on the steel strip 1 also moves accordingly. At this time, the rack 11 pushes the antenna 52 to drive the counterweight 53 to move up and down. At the same time, since the tooth peaks and tooth valleys of the rack 11 are irregular in height and the rack 11 extends continuously to both ends of the steel strip 1, the distance sensing component 54 continuously collects the distance information between it and the counterweight 53 and converts it into a wavy line. The peaks and troughs of the wavy line are also irregular, that is, the positions of various parts of the steel strip 1 can be determined by the wavy line change rules, peaks and trough values, and the numbering information (identity information) of various parts of the steel strip 1 can be obtained to register the information of the parts to be processed on the steel strip 1. Therefore, when processing the parts to be stamped, there is no need to scan the code through mechanical mechanisms or manual operations, thereby reducing processing costs, reducing equipment manufacturing costs, reducing labor costs, simplifying processing steps and improving processing safety.

[0054] Compared with traditional information recognition systems (barcode scanners or visual recognition systems), the opening and closing of the mold on the stamping station 4 will not cause significant damage to the hardware structure related to information recognition; in addition, compared with traditional information recognition systems (i.e., barcode scanners or visual recognition systems), since the rack 11 is located on the bottom surface of the steel strip 1, the metal debris generated by the stamping process will fall due to gravity. At the same time, since the tentacles 52 are in close contact with the rack 11, if metal debris appears on the rack 11, the metal debris will also be pushed away by the tentacles 52, thereby reducing the possibility of metal debris interfering with the information recognition process.

[0055] In some embodiments, a limiting groove 55 is provided on the side wall of the stamping cavity groove 41. When the steel strip 1 passes through the stamping cavity groove 41, the side edge of the steel strip 1 is located in the limiting groove 55. The top wall of the limiting groove 55 is provided with a code reading pulley 551 for contacting the top wall of the side edge of the steel strip 1. The code reading movable slot 5 is located on the bottom wall of the limiting groove 55, and the antenna 52 is on the same center line as the code reading pulley 551.

[0056] When the feeler 52 slides on the rack 11, the steel belt 1 is limited by the code reading pulley 551, so that the rack 11 pushes the feeler 52 to more stably drive the counterweight block 53 to move up and down.

[0057] In some embodiments, the counterweight 53 is installed with a magnet 531, and the distance sensing component 54 is a Hall IC for sensing the magnet 531, so that when the counterweight 53 drives the magnet 531 closer to or away from the Hall IC, the Hall IC obtains a wavy line by continuously recording and counting the changes in the magnetic field.

[0058] Compared with traditional infrared ranging, it is not affected by dust, metal debris, smoke and oil, thereby improving the stability and efficiency of ranging.

[0059] In some embodiments, the unwinder 2, the rewinder 3 and the stamping station 4 are all provided with a lifting mechanism. The lifting mechanism can be a traditional screw module 62, a pneumatic module and a cylinder module that can drive the steel strip 1 to rise and fall. After the stamping part is completed in the stamping cavity groove 41, the lifting mechanism is used to lift the steel strip 1 and move it away from the stamping cavity groove 41.

[0060] The stamping station 4 is equipped with a movable floating block 56. This floating block 56 is mounted on the stamping station 4 via a combination of sliders and rails, allowing it to rise and fall within the stamping station 4. The code reading slot 5, rocker 51, distance sensing component 54, and limit slot 55 are all mounted on the floating block 56. When the steel strip 1 is raised or lowered, the steel strip 1 drives the code reading slot 5, rocker 51, distance sensing component 54, and limit slot 55 to rise and fall synchronously, thereby offsetting the slope added to the wavy line when the steel strip 1 is raised or lowered. The floating block 56 can be positioned to the side of the stamping station 4 to prevent mold opening and closing movements.

[0061] After the part to be punched is punched in the punching cavity 41, the lifting mechanism lifts the steel strip 1 and moves it away from the punching cavity 41, thereby preventing the steel strip 1 (including the part to be punched) from being damaged by friction with the punching cavity 41 during the process of the steel strip 1 being moved into or away from each punching station 4 one by one.

[0062] When the lifting mechanism lifts the steel strip 1 and moves it away from the stamping cavity slot 41, the steel strip 1 drives the code reading movable slot 5, the rocker 51, the distance sensing component 54 and the limit slot 55 to rise synchronously, thereby offsetting the slope section added to the wave line when the steel strip 1 is lifted, thereby avoiding the steel strip 1 from interfering with the peak and trough values ​​of the wave line when it is lifted or lowered by the lifting mechanism.

[0063] In some embodiments, the unwinder 2, the rewinder 3 and the stamping station 4 are all provided with a lifting mechanism. After the stamping part is completed in the stamping cavity groove 41, the lifting mechanism is used to lift the steel strip 1 and move it away from the stamping cavity groove 41. The lifting mechanism can be a traditional screw module 62, pneumatic module and cylinder module that can drive the steel strip 1 to rise and fall. The height of the steel strip 1 lifted by the lifting mechanism is not higher than the highest height after the counterweight block 53 drives the tentacles 52 to rise, so that after the steel strip 1 is lifted, the tentacles 52 can still contact the rack 11. The lifting mechanism is provided with a lifting stroke sensor 57. The lifting stroke sensor 57 is used to record the lifting stroke when the steel strip 1 is lifted or lowered, and offset the slope section added to the wave line when the steel strip 1 is lifted or lowered. The lifting stroke sensor 57 can be an infrared distance sensor that can sense the distance between the sensor and the steel strip 1.

[0064] After the part to be punched is punched in the punching cavity 41, the lifting mechanism lifts the steel strip 1 and moves it away from the punching cavity 41, thereby preventing the steel strip 1 from being damaged by friction with the punching cavity 41 during the process of the part to be punched moving away from or into the punching cavity 41.

[0065] The setting of the lifting stroke sensor 57 is to record the lifting stroke of the steel belt 1 when it is lifted or lowered during the lifting or lowering process of the steel belt 1 lifting mechanism to offset the slope section added to the wave line, thereby avoiding interference with the peak and trough values ​​of the wave line.

[0066] In some embodiments, the metal part stamping system may further include:

[0067] The encoding station 6 is located between the unwinder 2 and the first stamping station 4. The encoding station 6 is provided with an engraving slot 61 and a screw module 62. The steel strip 1 passes through the engraving slot 61. The bottom wall of the engraving slot 61 is provided with an engraving movable slot 611. The screw module 62 drives an engraving knife 621 that is located in the engraving movable slot 611 and contacts the bottom wall of the steel strip 1.

[0068] The speed sensor is used to sense the moving speed of the steel strip 1 . The speed sensor may be a roller provided with a rotary encoder and in contact with the steel strip 1 .

[0069] When the winder 3 pulls the steel strip 1 out of the unwinder 2 and winds it up, the screw module 62 drives the engraving knife 621 close to or away from the top wall of the steel strip 1 according to the moving speed of the steel strip 1, thereby engraving irregular and uninterrupted racks 11 on the bottom surface of the steel strip 1 to achieve coding of various parts of the steel strip 1.

[0070] In some embodiments, the top wall of the engraving slot 61 is provided with an engraving pulley 63 for contacting the top wall of the steel strip 1 , and the engraving pulley 63 and the engraving knife 621 are on the same center line.

[0071] When the engraving knife 621 contacts the steel belt 1 , the engraving pulley 63 limits the steel belt 1 , so that the engraving knife 621 can more stably engrave the rack 11 on the steel belt 1 .

[0072] In some embodiments, the engraving knife 621 is provided with a sensing piece 622, and the speed sensor includes another distance sensor 7 and a timer;

[0073] When the screw module 62 drives the engraving knife 621 to approach or move away from the top wall of the steel strip 1, the other distance sensor 7 continuously collects the distance information between it and the sensor sheet 622 and converts it into a reference wave line, such as Figure 4 As shown, the timer is used to calculate the time required for the distance sensing component 54 to obtain the coincidence of the wave line with the reference wave line, thereby determining the speed of the steel strip 1;

[0074] The timer is also used to calculate the duration of a certain peak and trough value of the wave line or the reference wave line to determine whether the steel strip 1 has stopped moving.

[0075] In some embodiments, the metal stamping system further includes a knockout station 8, located between the winder 3 and the nearest stamping station 4. The knockout station 8 is used to knock the stamped product off the steel strip 1. After the portion to be stamped on the steel strip 1 is stamped into the product, the knockout station 8 knocks the stamped product off the steel strip 1, thereby achieving product unloading. The knockout station 8 can be a conventional cylinder module that drives the movement of a striking block to knock the product off the steel strip 1.

[0076] In order to further explain the metal part stamping system described in this specific embodiment, the following examples are listed.

[0077] The following is Example 1

[0078] This embodiment provides a metal part stamping system, which includes an unwinder 2, a rewinder 3, a stamping station 4 and a knocking-down station 8.

[0079] The unwinder 2 is wound with a steel strip 1 for stamping, and the bottom surface of the steel strip 1 is pre-engraved with an irregular and uninterrupted rack 11. The head end of the steel strip 1 is connected to the winder 3.

[0080] There are at least two stamping stations 4, each of which is equipped with a stamping cavity 41, a rocker 51, and a stamping device 42. When the reel 3 pulls the steel strip 1 from the unwinder 2 and rewinds it, the portion of the steel strip 1 to be stamped passes through all the stamping cavity 41 one by one. The bottom wall of the stamping cavity 41 is provided with a code reading slot 5. One end of the rocker 51 is provided with a feeler 52 that is movable and retractable within the code reading slot 5. The other end of the rocker 51 is provided with a counterweight 53 to ensure that the feeler 52 is in close contact with the rack 11. A distance sensing component 54 is provided below the counterweight 53. The stamping device 42 is used to stamp the portion to be stamped that passes through the stamping cavity 41.

[0081] The knock-off station 8 is located between the winder 3 and the nearest stamping station 4 . The knock-off station 8 is used to knock the products stamped on the steel strip 1 off the steel strip 1 .

[0082] The following is a working description of a metal part stamping system according to this embodiment.

[0083] The reel 3 pulls the steel strip 1 out of the unwinder 2 and reels it, so that the parts to be processed on the steel strip 1 are transferred one by one and in order to the die cavities of the stamping stations 4. The stamping devices 42 corresponding to the die cavities are then used for stamping. Thus, different forms of stamping are performed on the parts to be processed until the parts to be stamped are processed into products attached to the steel strip 1. When the movement of the steel strip 1 drives the products attached to it to move to the knock-off station 8, the knock-off station 8 knocks the products off the steel strip 1, thus completing the stripping.

[0084] When the steel belt 1 moves, the rack 11 also moves synchronously. At this time, the rack 11 pushes the antenna 52 to drive the counterweight 53 to move up and down. The distance sensing component 54 continuously collects the distance information between it and the counterweight 53 and converts it into a wave line. After that, each peak and trough value of the collected wave line is combined into a code, so that information of each part of the steel belt 1 is registered according to the code.

[0085] The following is Example 2

[0086] This embodiment provides a metal part stamping system, which includes an unwinder 2, a rewinder 3, an encoding station 6, a speed sensor, a stamping station 4 and a knocking-down station 8.

[0087] The unwinder 2 is wound with a steel strip 1 for stamping. The head end of the steel strip 1 is connected to the winder 3.

[0088] The encoding station 6 is located between the unwinder 2 and the first punching station 4. The encoding station 6 is provided with an engraving slot 61 and a screw module 62. The steel strip 1 passes through the engraving slot 61. The bottom wall of the engraving slot 61 is provided with an engraving movable slot 611. The screw module 62 drives an engraving knife 621 that is located in the engraving movable slot 611 and contacts the bottom wall of the steel strip 1. The engraving knife 621 is used to engrave the bottom surface of the steel strip 1 with irregular and uninterrupted racks 11. The top wall of the engraving slot 61 is provided with an engraving pulley 63 for contacting the top wall of the steel strip 1. The engraving pulley 63 and the engraving knife 621 are on the same center line.

[0089] The speed sensor is used to sense the moving speed of the steel strip 1 . The engraving knife 621 is provided with a sensing piece 622 . The speed sensor includes another distance sensor 7 and a timer.

[0090] The number of stamping stations 4 is at least two, and each stamping station 4 is provided with a stamping cavity slot 41, a rocker 51 and a stamping device 42. When the reel 3 pulls the steel strip 1 out of the unwinder 2 and rewinds it, the part of the steel strip 1 to be stamped passes through all the stamping cavity slots 41 one by one. The bottom wall of the stamping cavity slot 41 is provided with a code reading movable slot 5, and one end of the rocker 51 is provided with a tentacles 52 that are movable in the code reading movable slot 5, and the other end of the rocker 51 is provided with a counterweight block 53 so that the tentacles 52 and the rack 1 are aligned with each other. 1 is in close contact with the counterweight 53. A distance sensing component 54 is provided below the counterweight 53. The rack 11 pushes the feeler 52 to drive the counterweight 53 to move up and down. The distance sensing component 54 is used to continuously collect the distance information between it and the counterweight 53 and convert it into a wavy line. At the same time, it is used to collect each peak and trough value of the wavy line to combine into a code, so as to register information of each part of the steel strip 1 according to the code. The stamping device 42 is used to stamp the part to be stamped passing through the stamping cavity 41.

[0091] The knock-off station 8 is located between the winder 3 and the nearest stamping station 4 . The knock-off station 8 is used to knock the products stamped on the steel strip 1 off the steel strip 1 .

[0092] The following is a working description of a metal part stamping system according to this embodiment.

[0093] The reel 3 pulls the steel strip 1 out of the unreel 2 and reels it, so as to drive the steel strip 1 to move, so that various parts of the steel strip 1 are sequentially transferred to the encoding station 6, all the punching stations 4 and the knocking-off station 8.

[0094] When various parts of the steel strip 1 move to the encoding station 6, the screw module 62 drives the engraving knife 621 to approach or move away from the top wall of the steel strip 1 according to the moving speed of the steel strip 1, thereby engraving an irregular and uninterrupted rack 11 on the bottom surface of the steel strip 1; in this process, another distance sensor 7 continuously collects the distance information between it and the sensing sheet 622 and converts it to a reference wave line. The timer is used to calculate the time required for the distance sensing component 54 to obtain the match between the wave line and the reference wave line, thereby judging the speed of the steel strip 1 and making a preliminary registration of various parts of the steel strip 1; the timer is also used to calculate the duration of a certain peak and trough value of the wave line or the reference wave line to determine whether the steel strip 1 has stopped moving.

[0095] When various parts of the steel strip 1 move into the die-forming cavities of various stamping stations 4, the stamping devices 42 corresponding to the die-forming cavities are used for stamping, thereby performing different forms of stamping on the parts to be processed until the parts to be stamped are processed into products attached to the steel strip 1; at the same time, when the steel strip 1 moves, the rack 11 also moves synchronously. At this time, the rack 11 pushes the antenna 52 to drive the counterweight block 53 to move up and down, and the distance sensing component 54 continuously collects the distance information between it and the counterweight block 53 and converts it into a wavy line. Thereafter, each peak and trough value of the collected wavy line is combined into a code, so that the information of various parts of the steel strip 1 is registered according to the code to register the processing status of various parts of the steel strip 1 in each stamping station 4.

[0096] When the steel belt 1 moves and drives the products attached thereto to move to the knocking-off station 8, the knocking-off station 8 knocks the products off the steel belt 1, thereby completing the stripping.

[0097] The following is Example 3

[0098] This embodiment provides a metal part stamping system, which includes an unwinder 2, a rewinder 3, a stamping station 4 and a knocking-down station 8.

[0099] The unwinder 2 is wound with a steel strip 1 for stamping, and the bottom surface of the steel strip 1 is pre-engraved with an irregular and uninterrupted rack 11. The head end of the steel strip 1 is connected to the winder 3.

[0100] There are at least two stamping stations 4, each equipped with a stamping cavity 41, a floating block 56, and a stamping device 42. The floating block 56 is equipped with a rocker 51. When the reel 3 pulls the steel strip 1 from the unwinder 2 and rewinds it, the portion of the steel strip 1 to be stamped passes through each of the stamping cavities 41 one by one. The bottom wall of the stamping cavity 41 is provided with a code reading slot 5. One end of the rocker 51 is provided with a feeler 52 that moves upward and downward within the code reading slot 5. A counterweight 53 is provided at the other end of the rocker 51 to ensure close contact between the feeler 52 and the rack 11. The counterweight 53 is mounted with a magnet 531. Below the counterweight 53 is a distance sensing component 54, which is a Hall effect IC that senses the magnet 531. When the counterweight 53 drives the magnet 531 toward or away from the Hall effect IC, the Hall effect IC continuously records and statistically analyzes changes in the magnetic field, generating a wavy line. The sidewalls of the stamping cavity 41 are provided with a retaining groove 55. When the steel strip 1 passes through the stamping cavity 41, the side edge of the steel strip 1 is located within the retaining groove 55. The top wall of the retaining groove 55 is provided with a code reading pulley 551 for contacting the top wall of the side edge of the steel strip 1. The code reading movable notch 5 is located on the bottom wall of the retaining groove 55, and the feeler 52 is coaxial with the code reading pulley 551. The stamping device 42 is used to stamp and form the part to be stamped after passing through the stamping cavity 41.

[0101] The unwinder 2 , the rewinder 3 and the stamping station 4 are all provided with a lifting mechanism. After the stamping part completes stamping in the stamping cavity 41 , the lifting mechanism is used to lift the steel strip 1 and move it away from the stamping cavity 41 .

[0102] The knock-off station 8 is located between the winder 3 and the nearest stamping station 4 . The knock-off station 8 is used to knock the products stamped on the steel strip 1 off the steel strip 1 .

[0103] The following is a working description of a metal part stamping system according to this embodiment.

[0104] The reel 3 pulls the steel strip 1 out of the unwinder 2 and reels it, so that the parts to be processed on the steel strip 1 are transferred one by one and in order to the die cavities of the stamping stations 4. The stamping devices 42 corresponding to the die cavities are then used for stamping. Thus, different forms of stamping are performed on the parts to be processed until the parts to be stamped are processed into products attached to the steel strip 1. When the movement of the steel strip 1 drives the products attached to it to move to the knock-off station 8, the knock-off station 8 knocks the products off the steel strip 1, thus completing the stripping.

[0105] During the movement of the steel belt 1, the rack 11 also moves synchronously. At this time, the rack 11 pushes the antenna 52 to drive the counterweight 53 to move up and down. The distance sensing component 54 continuously collects the distance information between it and the counterweight 53 and converts it into a wave line. After that, each peak and trough value of the wave line is collected and combined into a code, so that information of each part of the steel belt 1 is registered according to the code.

[0106] In addition, during the movement of the steel belt 1, the steel belt 1 is lifted in advance by the lifting mechanism and moved away from the stamping cavity groove 41 to avoid damage caused by friction between the steel belt 1 and the stamping cavity groove 41. When the steel belt 1 stops moving, the lifting mechanism puts the steel belt 1 back into the stamping cavity groove 41; and when the steel belt 1 is lifted and lowered, the steel belt 1 drives the code reading movable groove 5, the rocker 51, the distance sensing component 54 and the limit groove 55 to rise synchronously to offset the slope section added to the wavy line when the steel belt 1 is lifted.

[0107] The following is Example 4

[0108] This embodiment provides a metal part stamping system, which includes an unwinder 2, a rewinder 3, a stamping station 4 and a knocking-down station 8.

[0109] The unwinder 2 is wound with a steel strip 1 for stamping, and the bottom surface of the steel strip 1 is pre-engraved with an irregular and uninterrupted rack 11. The head end of the steel strip 1 is connected to the winder 3.

[0110] There are at least two stamping stations 4, each of which is equipped with a stamping cavity 41, a rocker 51, and a stamping device 42. When the reel 3 pulls the steel strip 1 from the unwinder 2 and rewinds it, the portion of the steel strip 1 to be stamped passes through all the stamping cavity 41 one by one. The bottom wall of the stamping cavity 41 is provided with a code reading slot 5. One end of the rocker 51 is provided with a feeler 52 that is movable and retractable within the code reading slot 5. The other end of the rocker 51 is provided with a counterweight 53 to ensure that the feeler 52 is in close contact with the rack 11. A distance sensing component 54 is provided below the counterweight 53. The stamping device 42 is used to stamp the portion to be stamped that passes through the stamping cavity 41.

[0111] The unwinder 2, winder 3, and stamping station 4 are all equipped with a lifting mechanism. After the stamping portion is stamped in the stamping cavity 41, the lifting mechanism is used to lift the steel strip 1 and move it away from the stamping cavity 41. The lifting mechanism is equipped with a lifting stroke sensor 57, which is used to record the lifting stroke of the steel strip 1 when it is lifted or lowered, thereby offsetting the slope section added to the wavy line when the steel strip 1 is lifted or lowered.

[0112] The knock-off station 8 is located between the winder 3 and the nearest stamping station 4 . The knock-off station 8 is used to knock the products stamped on the steel strip 1 off the steel strip 1 .

[0113] The following is a working description of a metal part stamping system according to this embodiment.

[0114] The reel 3 pulls the steel strip 1 out of the unwinder 2 and reels it, so that the parts to be processed on the steel strip 1 are transferred one by one and in order to the die cavities of the stamping stations 4. The stamping devices 42 corresponding to the die cavities are then used for stamping. Thus, different forms of stamping are performed on the parts to be processed until the parts to be stamped are processed into products attached to the steel strip 1. When the movement of the steel strip 1 drives the products attached to it to move to the knock-off station 8, the knock-off station 8 knocks the products off the steel strip 1, thus completing the stripping.

[0115] During the movement of the steel belt 1, the rack 11 also moves synchronously. At this time, the rack 11 pushes the antenna 52 to drive the counterweight 53 to move up and down. The distance sensing component 54 continuously collects the distance information between it and the counterweight 53 and converts it into a wave line. After that, each peak and trough value of the wave line is collected and combined into a code, so that information of each part of the steel belt 1 is registered according to the code.

[0116] In addition, during the movement of the steel strip 1, the steel strip 1 is lifted in advance by the lifting mechanism and moved away from the stamping cavity groove 41 to avoid damage caused by friction between the steel strip 1 and the stamping cavity groove 41. When the steel strip 1 stops moving, the lifting mechanism puts the steel strip 1 back into the stamping cavity groove 41; and when the steel strip 1 is lifted and lowered, the lifting stroke sensor 57 records the lifting stroke when the steel strip 1 is lifted or lowered to offset the slope section added to the wave line when the steel strip 1 is lifted or lowered.
