Description

Technical Field

[0001] This invention relates to the field of stamping production equipment technology, and proposes an automated stamping production equipment for sheet metal. Background Technology

[0002] In the field of industrial sheet metal processing, continuous coil stamping is one of the core processes for sheet metal forming and hardware processing. This type of production process has extremely high requirements for the stability of the coil feeding, the flatness of the sheet metal conveying, and the positional accuracy of stamping and slitting.

[0003] In the existing technology, such as the automated stamping equipment for sheet metal stamping with announcement number CN111151623A, there are many defects in the automated stamping production of coils: First, the adaptability of the inner support structure of the feeding mechanism is extremely poor. For coils with different inner diameter specifications, the tensioning tooling needs to be changed frequently, resulting in long auxiliary operation time and low production efficiency. At the same time, the adjustable inner support structure in the existing technology has problems such as asynchronous movement of multiple support points and poor coaxiality of tensioning. During the feeding process, the coil is prone to radial swaying and axial movement, which causes the sheet metal to deviate during conveying and directly affects the accuracy of subsequent stamping and slitting. Secondly, although the existing technology has a pre-leveling mechanism, it can only achieve rough leveling after uncoiling and cannot solve the problem of secondary warping deformation during the conveying process after leveling. Moreover, its rigid leveling structure has poor adaptability and is prone to damage to the surface of the sheet metal, resulting in insufficient flatness of the sheet metal entering the stamping die, which can easily lead to stamping dimensional deviations, poor forming, and even die chipping and equipment damage. Thirdly, the punching waste generated during the stamping process is prone to accumulation and jamming. Some waste will adhere to the surface of the sheet metal and enter the subsequent process with the sheet metal, which can easily cause pressure and scratches on the surface of the sheet metal and affect the fixed-length cutting accuracy of the slitting process. Summary of the Invention

[0004] This invention proposes an automated sheet metal stamping production equipment, which solves the problems of poor material coil adaptability and insufficient feeding stability in the prior art, thus affecting the quality of subsequent processing.

[0005] The technical solution adopted in this invention is: An automated sheet metal stamping production equipment, characterized in that it includes a frame, and a feeding mechanism, a conveying device, a stamping mechanism and a slitting mechanism disposed on the frame; The feeding mechanism includes a feeding frame, a rotating shaft, a fixed plate, several supporting components, and an adjusting plate; The feeding frame is fixedly mounted on the machine frame, and the rotating shaft is rotatably mounted on the feeding frame.

The adjusting plate is sleeved on the rotating shaft, and the adjusting plate has arc-shaped guide grooves that correspond one-to-one with the support members. The support members pass through the corresponding arc-shaped guide grooves. When the adjusting plate rotates, the support members move along the guide grooves under the guidance of the arc-shaped guide grooves to support material rolls with different inner diameters. The rotation of the rotating shaft enables the material roll to be unloaded, and the conveying device is used to sequentially convey the unloaded sheet material to the stamping mechanism and the slitting mechanism.

[0006] As a further technical solution, the support component includes a mounting slider, a support rod, a support arm, a support plate, and two adjusting elastic components; The mounting slider is slidably mounted in the guide groove, and the support rod is fixedly mounted on the mounting slider and passes through the arc-shaped guide groove; The support arm is fixedly mounted on the support rod, and the support plate is hinged to the support arm. The support plate is used to abut against and support the inner wall of the material roll. Two adjusting elastic elements are symmetrically arranged on both sides of the support plate. One end of each adjusting elastic element is fixedly connected to the support arm, and the other end is fixedly connected to the support plate. The adjusting elastic element is used to drive the support plate to reset so as to adapt to material rolls with different inner diameters.

[0007] As a further technical solution, the support plate is an arc-shaped plate, and the ends of the support plate are hollow structures.

[0008] As a further technical solution, the rotating shaft has a threaded section, and the adjusting plate includes a plate body and an adjusting ring; The plate is sleeved on the rotating shaft, and the arc-shaped guide groove is formed on the plate. The adjusting ring is fixedly mounted on the plate body, and the adjusting ring is threadedly engaged with the threaded section. When the adjusting ring rotates, it drives the plate to rotate and simultaneously moves the plate along the axial direction of the rotation axis.

[0009] As a further technical solution, the plate body is also provided with an installation ring groove, and the feeding mechanism also includes an installation sleeve, a horizontal support ring frame and a support elastic element; The mounting sleeve is fixedly mounted on the fixed plate, and the mounting sleeve has a mounting groove. The horizontal support ring has an annular mounting end and a movable end. The annular mounting end is installed in the mounting ring groove, and the movable end slides in the mounting groove as the plate moves axially along the rotation axis. One end of the supporting elastic element is fixedly connected to the bottom of the mounting groove, and the other end is fixedly connected to the moving end. The supporting elastic element is used to provide a force that makes the annular mounting end press against the plate to ensure the horizontal state of the plate, thereby ensuring the synchronous movement of the multiple mounting sliders.

[0010] As a further technical solution, the stamping mechanism includes a stamping frame, an extrusion assembly, a stamping die, and a stamped part; The stamping frame is fixedly mounted on the machine frame, and the stamping frame is provided with an installation clearance groove; The extrusion assembly is located at the feed end of the stamping frame and is used to extrude and flatten the sheet metal to be stamped. The stamping die is detachably installed in the mounting clearance groove; The stamping part is slidably mounted on the stamping frame. After sliding, the stamping part cooperates with the stamping die to complete the stamping operation on the sheet metal.

[0011] As a further technical solution, the extrusion assembly includes a rotating roller, an extrusion drive, an extrusion frame, a moving plate, an extrusion roller, and an extrusion elastic element; The rotating roller is rotatably installed in the mounting clearance groove, and the extrusion drive is fixedly installed on the stamping frame. The extrusion drive is used to drive the rotating roller to rotate. The extrusion frame is fixedly mounted on the stamping frame body. The extrusion frame has an extrusion groove. The movable plate is slidably installed in the extrusion groove. The extrusion roller is rotatably mounted on the movable plate. One end of the extrusion elastic element is fixedly connected to the movable plate, and the other end is fixedly connected to the extrusion frame. The extrusion elastic element is used to provide the extrusion force that causes the extrusion roller to press against the rotating roller.

[0012] As a further technical solution, the stamping frame is also provided with a waste discharge groove, the waste discharge groove is an inclined structure, and the waste discharge groove is connected to the installation clearance groove. The waste discharge groove is located below the stamping die. The frame is also equipped with a waste collection box, and the lowest inclined end of the waste discharge chute is located above the waste collection box. The waste generated by stamping is introduced into the waste collection box through the waste discharge chute.

[0013] As a further technical solution, the slitting mechanism includes a slitting frame, a waste scraper, a bottom cutter, and slitting components; The slitting frame is fixedly mounted on the machine frame, and the waste scraper is mounted at the feed end of the slitting frame to scrape off excess waste material adhering to the sheet after stamping. The bottom cutter is fixedly mounted on the surface of the slitting frame, and the slitting component is slidably mounted on the slitting frame in the vertical direction. After the slitting component moves, it cooperates with the bottom cutter to cut the board material horizontally to a fixed length.

[0014] As a further technical solution, a waste guide channel is provided on the cutting frame. The waste guide channel has an inclined structure, and the discharge end of the waste guide channel is connected to the waste collection box. The waste scraping component includes a bottom scraper, a scraping frame, and an upper surface scraper; the bottom scraper is fixedly mounted on the cutting frame, the scraping frame is fixedly mounted on the cutting frame, the scraping frame has a scraping mounting groove, and the upper surface scraper is detachably mounted on the scraping mounting groove. A scraping channel is formed between the upper surface scraper and the bottom surface scraper. When the board passes through the scraping channel, the waste material that is raised on the board is scraped off and guided to the waste guide groove, and then falls into the waste collection box.

[0015] The beneficial effects of adopting the above technical solution are as follows: This invention integrates a feeding mechanism, conveying device, stamping mechanism, and slitting mechanism on a frame to achieve continuous automated production of the entire process from coil feeding, sheet metal stamping, and finished product slitting. It eliminates the need for manual auxiliary handling, significantly improving production efficiency, reducing labor costs, and adapting to the needs of large-scale continuous production. The feeding mechanism employs a circumferentially arranged multi-support component combined with an arc-shaped guide groove on an adjusting plate. The rotation of the adjusting plate synchronously drives multiple support components to move radially along the guide groove of the fixed plate, achieving rapid tensioning support for coils of different inner diameters. This eliminates the need to change tooling, demonstrating strong adaptability and fundamentally solving the problems of coil shaking, slippage, and sheet metal deviation during feeding. It provides a stable feeding foundation for subsequent stamping and slitting. Furthermore, the invention features a compact overall structure and small footprint, effectively addressing the pain points of traditional split-type equipment, such as poor process connections, low automation, and poor coil adaptability, ensuring continuous stability and finished product precision in sheet metal processing.

[0027] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. The invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the accompanying drawings described below are merely some embodiments of the present invention. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort.

[0028] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] Reference Figures 1-10The first embodiment of the present invention proposes an automated sheet metal stamping production equipment including a frame 1. The frame 1 is a rigid frame structure integrally welded and serves as the installation base for the entire equipment, providing stable installation support and operating benchmarks for the other mechanisms, and ensuring the positional accuracy and coordination accuracy between the mechanisms.

[0030] The frame 1 is equipped with a feeding mechanism, a conveying device, a stamping mechanism and a slitting mechanism arranged in sequence along the sheet material conveying direction. The four working stations are arranged coaxially to form a continuous production line, realizing the continuous operation of the whole process of coil feeding, sheet material conveying, stamping and forming and fixed length slitting.

[0031] The feeding mechanism is used to tighten and fix material rolls of different inner diameters and to automatically unload them. It includes a frame, a rotating shaft 3, a fixed plate 4, several support components, and an adjusting plate. The frame is fixedly installed at the feeding end of the frame 1, providing stable support for the rotating shaft 3. The rotating shaft 3 is rotatably mounted on the frame via a bearing seat, and its axis is perpendicular to the conveying direction of the sheet material. It can be driven to rotate by a matching unloading drive mechanism to achieve uniform unloading of the material rolls. The fixed plate 4 is fixedly installed at the end of the rotating shaft 3, coaxial with the rotating shaft 3, and can rotate synchronously with the rotating shaft 3. On the side of the fixed plate 4 facing the adjusting plate, multiple guide grooves 5 are evenly opened circumferentially. The guide grooves 5 extend radially along the fixed plate 4, and multiple support components are slidably installed in the guide grooves 5, allowing them to reciprocate radially towards or away from the axis of the rotating shaft 3 along the guide grooves 5. The adjusting plate is sleeved on the rotating shaft 3, coaxial with the fixed disk 4 and spaced apart. The adjusting plate has arc-shaped guide grooves 6 that correspond one-to-one with the support members. The arc-shaped guide grooves 6 are eccentric arc-shaped grooves, and the distances between their two ends and the axis of the rotating shaft 3 are different. The support members pass through the corresponding arc-shaped guide grooves 6. When the adjusting plate rotates around the axis of the rotating shaft 3, the groove wall of the arc-shaped guide groove 6 will apply a radial driving force to the support members, guiding the support members to move radially along the guide groove 5 on the fixed disk 4, thereby realizing the synchronous tensioning and contraction of multiple support members, adapting to the internal support requirements of material coils with different inner diameters.

[0032] To ensure stable support of the material roll's inner wall, the support system includes a mounting slider 7, a support rod 8, a support arm 9, a support plate 10, and two adjusting elastic elements 11. The mounting slider 7 is slidably fitted within the guide groove 5 of the fixed plate 4, with a clearance fit to the groove wall to ensure smooth sliding and positional accuracy. The support rod 8 is vertically fixed to the end face of the mounting slider 7 facing the adjusting plate, and passes through the corresponding arc-shaped guide groove 6 on the adjusting plate, allowing it to slide along the arc-shaped guide groove 6 as the mounting slider 7 moves. The support arm 9 is fixedly installed at the end of the support rod 8 away from the mounting slider 7, extending towards the inner wall of the material roll. The support plate 10 is hinged to the end of the support arm 9 via a hinge shaft. The outer surface of the support plate 10 abuts against the inner wall of the material roll. The hinged structure allows the support plate 10 to adaptively adjust its angle, better conforming to the inner wall curvature of material rolls with different inner diameters, ensuring sufficient support contact area. The two adjusting elastic elements 11 are symmetrically arranged on the support plate. On both sides of the hinge shaft of 10, one end of the adjusting elastic element 11 is fixedly connected to the support arm 9, and the other end is fixedly connected to the end of the support plate 10. When the support plate 10 moves radially with the support and fits the inner wall of the material roll with different inner diameters, the adjusting elastic element 11 can drive the support plate 10 to rotate adaptively and then reset, ensuring that the support plate 10 can always stably fit the inner wall of the material roll, while avoiding damage such as indentations and scratches caused by rigid contact to the inner wall of the material roll. Furthermore, the support plate 10 is an arc plate, and its outer arc surface is adapted to the inner wall curved surface of the material roll, which can further improve the stability of the fit support. The end of the support plate 10 is a hollow structure, which reduces the overall weight of the support while ensuring the overall structural strength, reduces the rotational load of the rotating shaft 3, and improves the stability of the feeding rotation.

[0033] To achieve precise adjustment of the rotation and axial position of the adjusting plate, a threaded section is provided on the outer circumference of the rotating shaft 3. The adjusting plate includes a plate body 12 and an adjusting ring 13. The plate body 12 is sleeved on the rotating shaft 3, and arc-shaped guide grooves 6 are evenly opened on the plate body 12. The adjusting ring 13 is fixedly installed on the side of the plate body 12 facing the fixed plate 4. The inner ring of the adjusting ring 13 is provided with an internal thread, which is threadedly engaged with the threaded section on the rotating shaft 3. When the adjusting ring 13 is rotated, the adjusting ring 13 will move axially along the rotating shaft 3, and at the same time drive the plate body 12 to rotate and move axially synchronously. In turn, the arc-shaped guide groove 6 drives the support to move radially, thereby realizing the adjustment of the tension support. The threaded engagement method can achieve precise control of the adjustment amount, and also has a self-locking function to ensure the stability of the tension support state and prevent loosening or retraction during the feeding process.

[0034] To ensure that the plate 12 is always in a horizontal state parallel to the fixed plate 4 and to avoid problems such as asynchronous movement of multiple support components and poor coaxiality of tension caused by the plate 12 being tilted, an annular mounting groove 14 is also provided on the end face of the plate 12 facing the fixed plate 4. The feeding mechanism also includes a mounting sleeve 15, a horizontal support ring frame 16 and a support elastic element 17. The mounting sleeve 15 is fixedly installed on the end face of the fixed plate 4 facing the plate 12 and is coaxially arranged with the rotating shaft 3. An axially extending mounting groove is provided on the end face of the mounting sleeve 15 facing the plate 12. The horizontal support ring frame 16 is an annular frame structure with an integrally formed annular mounting end 18 and a movable end 19. The annular mounting end 18 is embedded in the mounting groove 14 of the plate 12 and can rotate synchronously with the plate 12. The movable end 19 is inserted into the mounting groove of the mounting sleeve 15 and can slide along the mounting groove as the plate 12 moves axially. One end of the support elastic element 17 is fixedly connected to the bottom of the mounting groove, and the other end is fixedly connected to the end of the moving end 19. The support elastic element 17 is always in a compressed state, which can provide a continuous elastic force to push the annular mounting end 18 of the horizontal support ring frame 16 to always press against the mounting ring groove 14 of the plate 12, thereby forming a uniform axial support for the plate 12 in the circumferential direction. This ensures that the plate 12 is always in a horizontal state parallel to the fixed plate 4, and avoids the plate 12 from tilting or shaking. It fundamentally ensures the synchronous movement of multiple support elements and improves the coaxiality of the material roll tension and the stability of the material release.

[0035] The conveying device is located between the feeding mechanism and the stamping mechanism. It adopts an integrated structure of "rough leveling section + conveying section". It can first unwind and rough level the sheet material after it is unloaded by the feeding mechanism, and then convey it to the subsequent stamping mechanism and slitting mechanism at a uniform speed and stably. At the same time, it can work with the feeding drive mechanism to realize the control of the tension of the sheet material conveying throughout the process, so as to avoid problems such as loosening, stretching deformation or deviation of the sheet material during the conveying process.

[0036] The coarse leveling section of the conveying device can adopt an axisymmetric cross-set leveling roller structure disclosed in the prior art such as CN111151623A. Specifically, it includes several sets of first leveling rollers and second leveling rollers arranged alternately. The sheet passes through the multiple sets of leveling rollers in an S-shaped path. Through repeated alternating bending action, the large curvature wave deformation, winding stress and most of the internal residual stress generated when the roll is unwound are eliminated. The end of the coarse leveling section is connected to the subsequent conveying device to perform preliminary leveling of the sheet. The linear speed of all conveying rollers is synchronized with the running speed of the unloading drive mechanism and the stamping mechanism in real time, so as to realize the control of the sheet conveying tension.

[0037] The stamping mechanism is used to realize continuous stamping forming of sheet metal. It includes a stamping frame 20, an extrusion assembly, a stamping die 21, and stamped parts 22. The stamping frame 20 is fixedly installed on the frame 1 to provide rigid support for the stamping operation. A through mounting clearance groove 23 is opened on the stamping frame 20, which forms a conveying channel for the sheet metal and a stamping operation space. The extrusion assembly is located at the feeding end of the stamping frame 20, on the material receiving side of the stamping die 21. It is used to extrude, flatten, and straighten the sheet metal before it enters the stamping die 21, eliminating warping and unevenness of the sheet metal, ensuring the flatness of the sheet metal entering the die, and improving stamping accuracy. The stamping die 21 is detachably installed in the mounting clearance groove 23 and can be quickly replaced according to different stamping forming requirements, adapting to different product production needs and having strong versatility. The stamping part 22 is slidably mounted on the stamping frame 20 in the vertical direction, located directly above the stamping die 21. It can be driven to slide vertically back and forth by the matching stamping drive mechanism. When the stamping part 22 slides down, it cooperates with the stamping die 21 below to complete the stamping operation on the sheet metal.

[0038] To achieve stable, flat, and synchronous conveying of the sheet metal, the extrusion assembly includes a rotating roller 24, a drive unit, an extrusion frame 26, a moving plate 27, an extrusion roller 28, and an extrusion elastic element 29. The rotating roller 24 is rotatably mounted in the mounting clearance groove 23 via bearings, with its top surface flush with the conveying reference surface of the sheet metal. The drive unit, a servo motor, is fixedly mounted on the outside of the stamping frame 20. The output end of the drive unit is fixedly connected to the rotating shaft of the rotating roller 24, driving the roller 24 to rotate at a uniform speed, providing auxiliary driving force for the conveying of the sheet metal and ensuring the synchronicity of the sheet metal conveying. The extrusion frame 26 is fixedly mounted on the stamping frame 20, located directly above the rotating roller 24. The extrusion frame 26 has a vertically extending extrusion groove 30. The moving plate 27 is slidably mounted within the extrusion groove 30 via a slider, allowing it to slide vertically back and forth along the extrusion groove 30. The extrusion roller 28 is rotatably mounted at the lower end of the moving plate 27 via bearings, positioned vertically opposite the rotating roller 24. The extrusion elastic element 29 is a compression spring, with one end fixedly connected to the upper end face of the moving plate 27 and the other end fixedly connected to the top of the extrusion frame 26. The extrusion elastic element 29 is always in a compressed state, which can provide a continuous downward elastic extrusion force, pushing the moving plate 27 to drive the extrusion roller 28 to move downward, so that the extrusion roller 28 always presses against the rotating roller 24, forming a stable elastic extrusion on the plate passing between the two. This can not only achieve the flattening and straightening of the plate, but also adapt to plates of different thicknesses, avoiding damage to the surface of the plate caused by rigid extrusion.

[0039] To achieve automatic discharge and collection of stamping waste, a waste discharge trough 31 is provided at the lower part of the stamping frame 20. The waste discharge trough 31 is an inclined through trough, with its high end connected to the bottom of the installation clearance trough 23 and located directly below the stamping die 21. The punching waste generated during stamping can fall directly into the waste discharge trough 31. The lowest inclined end of the waste discharge trough 31 faces the waste collection box 32 set on the frame 1 and is located above the opening of the waste collection box 32. The waste falling into the waste discharge trough 31 can automatically slide down the inclined trough under the action of gravity and be guided into the waste collection box 32, thereby realizing the automatic centralized collection of stamping waste, avoiding the accumulation and jamming of waste in the die, and ensuring the continuous and stable operation of stamping.

[0040] The slitting mechanism is used to cut the continuous sheet metal after stamping into a horizontal, fixed-length section according to a preset finished size. It includes a slitting frame 33, a waste scraper, a bottom cutter 34, and a slitting component 35. The slitting frame 33 is fixedly mounted on the frame 1, located on the discharge side of the stamping mechanism, providing stable support for the slitting operation. The waste scraper is located at the feed end of the slitting frame 33, on the upper and lower sides of the sheet metal conveying channel. It is used to scrape away excess waste and burrs adhering to the upper and lower surfaces of the sheet metal after stamping, preventing waste from entering the slitting station with the sheet metal and causing damage or dimensional deviations in the slitting process. The bottom cutter 34 is fixedly installed on the upper surface of the slitting frame 33, with its blade flush with the conveying reference surface of the board. The slitting piece 35 is slidably installed on the slitting frame 33 in the vertical direction via a vertical guide rail, located directly above the bottom cutter 34. It can be driven to move vertically reciprocatingly by a matching slitting drive mechanism. When the slitting piece 35 moves downward, its blade cooperates with the blade of the bottom cutter 34 to perform a horizontal fixed-length cut on the board, obtaining a finished board of a preset size.

[0041] To achieve automatic scraping and unified collection of waste material adhering to the surface of the sheet metal, a waste material guide trough 36 is also provided on the slitting frame 33. The waste material guide trough 36 has an inclined structure, with its inlet end connecting to the outlet side of the waste material scraper, and the outlet end at the lowest inclined end connecting to the waste material collection box 32. The scraped waste material can automatically slide down along the waste material guide trough 36 into the waste material collection box 32, achieving unified and centralized collection with stamping waste. The waste material scraper includes a bottom scraper 37, a scraping frame 38, and an upper scraper 39. The bottom scraper 37 is fixedly installed on the slitting frame 33, with its scraping blade facing upwards and in contact with the lower surface of the sheet metal, used to scrape off the waste material and burrs adhering to the lower surface of the sheet metal. The scraping frame 38 is fixedly installed on the slitting frame 33, spanning the conveying channel of the sheet material. The scraping frame 38 has a scraping mounting groove 40. The upper surface scraper 39 is detachably installed on the scraping mounting groove 40 by bolts, with its scraping blade facing downwards and in contact with the upper surface of the sheet material. It is used to scrape off waste and burrs adhering to the upper surface of the sheet material. The detachable installation method allows for quick replacement of the appropriate upper surface scraper 39 according to the thickness and width of the sheet material, ensuring effective scraping. A scraping channel 41 is formed between the upper surface scraper 39 and the bottom scraper 37 for the sheet material to pass through. When the sheet material passes through the scraping channel 41, the raised waste and burrs adhering to its upper and lower surfaces are scraped off simultaneously by the upper and lower scrapers. The scraped waste is guided by the scrapers into the waste guide trough 36 behind it, and then falls into the waste collection box 32 along the inclined waste guide trough 36, completing the automatic cleaning and collection of waste.

[0042] The complete workflow of the automated sheet metal stamping production equipment in this embodiment is as follows: Production Preparation: Based on the inner diameter specifications of the material roll to be produced, adjust the position of the support components of the feeding mechanism, rotate the adjusting ring 13 to drive the plate 12 to rotate, and guide multiple support components to synchronously shrink inward along the guide groove 5 of the fixed plate 4 through the arc-shaped guide groove 6, so that the outer contour dimension of multiple support plates 10 is smaller than the inner diameter of the material roll, and put the material roll on the outside of multiple support plates 10. Rotate the adjusting ring 13 in the opposite direction to drive the plate 12 to rotate in the opposite direction, drive multiple support components to synchronously tighten outward, so that the support plates 10 fit tightly against the inner wall of the material roll, and complete the tightening and fixing of the material roll; according to the thickness of the sheet and the stamping forming requirements, replace the appropriate stamping die 21 and the upper surface scraper 39, and adjust the pre-tightening force of the extrusion elastic element 29 of the extrusion assembly to ensure the flatness of the sheet; set the feeding speed, conveying speed, stamping frequency and cutting length parameters of the equipment to complete the pre-production preparation work.

[0043] Automated feeding and conveying: When the equipment is started, the rotating shaft 3 rotates at a constant speed under the drive of the feeding drive mechanism, which drives the material roll to rotate synchronously to achieve feeding. After feeding, the sheet material enters the conveying device, which conveys it to the subsequent stamping mechanism at a constant speed and stably. During the conveying process, the conveying device works with the feeding drive mechanism to control the conveying tension of the sheet material to ensure the smoothness of the sheet material conveying and avoid problems such as looseness, deviation, and stretching deformation.

[0044] Sheet flattening and automated stamping: After the sheet enters the stamping mechanism, it first passes between the rotating roller 24 and the extrusion roller 28 of the extrusion assembly. Under the action of the extrusion elastic element 29, the extrusion roller 28 and the rotating roller 24 form a stable elastic extrusion on the sheet, flattening and straightening the sheet and eliminating warping and unevenness. The flattened sheet enters the stamping station of the stamping die 21. The stamping part 22 slides vertically back and forth under the drive of the stamping drive mechanism, cooperating with the stamping die 21 to complete the continuous stamping operation on the continuously conveyed sheet. The punching waste generated by stamping falls directly into the waste discharge trough 31 below, and automatically slides down the inclined trough into the waste collection box 32, completing the automatic collection of stamping waste.

[0045] Waste removal and automated slitting: After stamping, the sheet metal continues to be conveyed to the slitting mechanism. First, it passes through the waste removal component at the feeding end of the slitting frame 33. When the sheet metal passes through the scraping channel 41 between the upper surface scraper 39 and the bottom surface scraper 37, the waste and burrs attached to its upper and lower surfaces are scraped off simultaneously. The scraped waste is guided into the waste guide trough 36 and slides down the inclined trough into the waste collection box 32, completing the automatic cleaning of waste on the sheet metal surface. The cleaned sheet metal is conveyed to the slitting station. When the sheet metal is conveyed to the preset fixed length size, the slitting component 35 moves downward under the drive of the slitting drive mechanism and cooperates with the bottom cutter 34 to complete the transverse fixed length cutting of the sheet metal, obtaining the finished sheet metal of the preset size.
