Description

Technical Field

[0001] This invention belongs to the field of metal processing technology, and specifically relates to a forming device and forming method for processing metal tableware. Background Technology

[0002] In the processing of metal tableware, products with three-dimensional shapes (such as metal spoons) typically employ a two-step stamping process. First, a flat metal sheet is stamped into a two-dimensional planar semi-finished product, containing the outline of the spoon face and the outline of the spoon handle. Then, the spoon face portion of this planar semi-finished product is placed on a curved mold, and a second stamping process plastically deforms it into a three-dimensional curved structure, while the handle portion remains flat or is subsequently processed to achieve the desired angle. In existing technologies, the positioning method for the second stamping mainly relies on manual operation: the operator manually picks up or grips the planar semi-finished product, aligns its spoon face with the cavity of the curved mold, places it in, and then starts the stamping machine to complete the forming. Although some automated production lines use robotic arms for loading, the basic principle is still based on the alignment of the spoon face outline with the curved mold.

[0003] However, the aforementioned existing technologies have significant technical problems in actual production. First, because the stamping rate of the stamping press remains constant, manual placement makes it difficult to guarantee that the entire spoon surface can be accurately and stably placed in the precise position of the curved die every time. When the semi-finished product has a slight angular deflection or positional shift, the stamped product will exhibit defects such as a skewed spoon surface, asymmetrical edges, localized overstretching, or even breakage, resulting in significant material waste and a decrease in yield. Even with a robotic arm, without a high-precision visual positioning or guiding mechanism, positioning failure may still occur due to slight warping of the semi-finished product itself or errors in the incoming material position. Furthermore, the existing technology relies solely on the fit between the spoon surface and the die cavity for positioning, lacking constraint on the spoon handle. During the stamping process, the semi-finished product is prone to slipping due to force, further exacerbating forming errors.

[0004] Therefore, how to improve the positioning accuracy and operational consistency of semi-finished products during secondary stamping and reduce scrap caused by positioning misalignment is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] To address the aforementioned problems in the prior art, this invention provides a forming apparatus and a forming method for processing metal tableware.

[0006] The objective of this invention can be achieved through the following technical solutions: The present invention discloses a forming device for processing metal tableware, comprising a forming table, wherein a stamping component, a storage component, and a feeding component are provided on the forming table. The storage component includes a storage box and a guide rod vertically arranged inside the storage box. The internal cross-section of the storage box is adapted to the contour of a metal sheet. A plurality of through holes on the metal sheet spoon handle segments are fitted onto the guide rod and stacked inside the storage box. The feeding component pushes the metal sheet spoon surface segment located at the bottom of the storage box to rotate based on the guide rod to the bottom of the stamping component for stamping.

[0007] As a further embodiment of the present invention, the feeding assembly includes a turntable, a clamping mechanism and a motor. The output shaft of the motor is connected to the turntable. The clamping mechanism is disposed on the turntable. The clamping mechanism rotates with the turntable to the position of the metal sheet and clamps and pushes the metal sheet.

[0008] As a further embodiment of the present invention, the clamping mechanism includes a fixed plate and a telescopic plate. The telescopic plate is elastically telescopically disposed on the side of the fixed plate. A plurality of rubber columns are disposed on the top surface of the fixed plate away from the telescopic plate. The height of the telescopic plate and the rubber columns is higher than the height of the fixed plate. Both sides of the rubber columns near and away from the telescopic plate are inclined surfaces. A clamping area for the metal sheet is formed between the telescopic plate and the rubber columns.

[0009] As a further embodiment of the present invention, the stamping assembly includes a stamping table, an upper die, and a lower die. A hydraulic rod is provided on the stamping table, the upper die is disposed at the bottom of the hydraulic rod, and the lower die is disposed on the stamping table.

[0010] As a further embodiment of the present invention, the lower mold is a hemispherical convex structure adapted to the inner side of the metal sheet spoon section, the upper mold is a hemispherical concave structure adapted to the outer side of the lower mold and the metal sheet spoon section, and the stamping table forms an inclined surface downwards towards the storage box based on the edge of the hemispherical convex structure.

[0011] As a further embodiment of the present invention, the hemispherical convex structure of the lower die is provided with a limiting block on the side away from the material storage component. The limiting block abuts against the metal sheet before stamping and is limited thereto. The limiting block separates from the metal sheet after stamping.

[0012] As a further embodiment of the present invention, the storage box has a discharge port on one side of the rotating feeding direction of the turntable, and the thickness of the discharge port is less than the thickness of the two metal sheets.

[0013] As a further embodiment of the present invention, the guide rod includes a straight rod section and a curved rod section. The curved rod section extends laterally from the bottom of the storage box. The bottom of the curved rod section is connected and fixed to the material collection device, and the top of the curved rod section is detachably connected to the straight rod section.

[0014] As a further embodiment of the present invention, it also includes a control device and a sensor, wherein the sensor is disposed on the limit block, and the control device is electrically connected to the sensor, the motor and the hydraulic rod, and the control device instructs the motor and the hydraulic rod to operate according to the sensor data.

[0015] A forming method for processing metal tableware, applicable to a forming apparatus for processing metal tableware, includes the following steps: S1: The metal raw material is initially stamped to form a metal sheet with through holes in the handle section; S2: Fit the through hole of the metal sheet onto the straight section of the guide rod and stack them into the storage box; S3: The start control device commands the motor to rotate. The turntable starts to rotate under the drive of the motor. The inner side of the telescopic plate on the turntable abuts against one side of the metal sheet at the bottom of the storage box and stretches under the force. The other side of the metal sheet abuts against the rubber column, so that the telescopic plate and the rubber column clamp the metal sheet. The turntable continues to rotate until the side of the metal sheet abuts against the limit block and the sensor. At the same time, the control device commands the motor to stop. S4: After the control device obtains the sensor information, it instructs the hydraulic rod to move and punch the metal sheet, so that the spoon section of the metal sheet bends and separates from the limit block and the sensor. At the same time, the handle section of the metal sheet is tilted downwards on the inclined surface of the stamping table along the bending direction of the spoon section, so that the through hole is transferred from the straight rod section to the bent rod section. S5: After the hydraulic cylinder completes the stamping action, the control device commands the motor to continue rotating, and the clamping mechanism pushes the metal sheet to separate from the lower die, so that the metal sheet slides down along the extension direction of the bent rod section to the collection device for collection.

[0016] The beneficial effects of this invention are as follows: First, the semi-finished metal sheet, which has undergone initial planar punching and has a through hole in the handle section, is fitted onto the vertical guide rod section inside the storage box through the through hole. Stacking and positioning are achieved by adapting the inner wall contour of the storage box to the shape of the metal sheet. During operation, the control device instructs the motor to drive the turntable to rotate. The clamping mechanism fixed on the turntable rotates with the turntable to the bottom outlet of the storage box. Its elastic telescopic plate abuts against one side of the metal sheet and generates clamping force. The inclined surface of the rubber column on the other side automatically guides the metal sheet to be aligned, forming a stable clamp. As the turntable continues to rotate, the clamping mechanism pushes the bottom metal sheet out from the outlet with the guide rod as the rotating axis, and rotates along the inclined surface of the stamping table to the top of the lower die until the front end of the metal sheet contacts the limiting block and sensor on the side of the lower die, achieving precise mechanical positioning. At this time, the control device instructs the motor to stop. Subsequently, based on the sensor's positioning signal, the control device instructs the hydraulic rod to drive the upper die downwards, cooperating with the hemispherical, convex lower die to stamp the metal spoon face section into a three-dimensional curved surface. Simultaneously, the metal spoon handle section, guided by the inclined surface of the stamping table, naturally bends downwards, forming a three-dimensional angle between the spoon face and the handle, with the through hole on the handle section transitioning from the straight section of the guide rod to the curved section. After stamping, the upper die returns, and the control device again instructs the motor to rotate. The clamping mechanism pushes the finished product away from the lower die, allowing it to automatically slide down along the extension direction of the curved section of the guide rod into the collecting device, completing one work cycle. The entire process achieves fully automated continuous operation from stacking and storing materials, automatic material retrieval, rotating feeding, mechanical limiting, stamping, to automatic unloading, effectively avoiding positioning errors and material waste caused by manual placement with misalignment.

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0020] like Figures 1-4 As shown, a forming apparatus for processing metal tableware according to the present invention includes a forming table. A stamping assembly, a storage assembly, and a feeding assembly are arranged on the forming table. The storage assembly includes a storage box 1 and a guide rod vertically arranged inside the storage box 1. The internal cross-section of the storage box 1 is adapted to the contour of a metal sheet. A plurality of through holes on the metal sheet spoon handle segments are fitted onto the guide rod and stacked within the storage box 1. The feeding assembly pushes the metal sheet spoon surface segments at the bottom of the storage box 1 to rotate based on the guide rod to below the stamping assembly for stamping. The storage box 1 is connected to the forming table via a connecting structure.

[0021] The internal cross-sectional shape of the storage bin 1 perfectly matches the planar contour of the metal sheet (e.g., a ladle shape), so the metal sheet will not rotate circumferentially within the storage bin 1, but can only move vertically. A guide rod passes through a through-hole in the handle section of the metal sheet, further restricting the horizontal displacement of the metal sheet in its stacked state. When the feeding assembly pushes the ladle section of the bottommost metal sheet from the bottom, the metal sheet is pushed out along the outlet at the bottom of the storage bin 1, using the guide rod as a pivot, and rotates a certain angle around the guide rod before reaching the bottom of the stamping assembly. Because the relative position between the bottom of the storage bin 1 and the stamping assembly is fixed, each fed metal sheet can be precisely positioned at the stamping center.

[0022] By utilizing the fit between the metal sheet's own contour and the inner wall of the storage bin 1, as well as the fit between the through hole and the guide rod, dual guidance is achieved, ensuring that the angle and position height of each metal sheet are consistent during delivery, eliminating the need for manual alignment or visual correction. The stacking method saves loading space, and gravity-based automatic unloading eliminates the need for additional lifting mechanisms, reducing costs. The rotating feeding method ensures that the metal sheet remains connected to the scoop handle and guide rod throughout its movement, preventing it from falling off or shifting midway.

[0023] As a further embodiment of the present invention, the feeding assembly includes a turntable 31, a clamping mechanism 32 and a motor. The motor is mounted on the forming table, and the output shaft of the motor is connected to the turntable 31. The clamping mechanism 32 is mounted on the turntable 31, and the clamping mechanism 32 rotates with the turntable 31 to the position of the metal sheet and clamps and pushes the metal sheet.

[0024] The motor drives the turntable 31 to rotate intermittently. The clamping mechanism 32 is fixed to the turntable 31 and rotates with it. When the turntable 31 rotates to a certain angle, the clamping mechanism 32 aligns with the lowest metal sheet at the bottom outlet of the storage bin 1; the clamping mechanism 32 actuates, clamping the metal sheet; then the turntable 31 continues to rotate, and the clamping mechanism 32 drives the metal sheet to rotate around the guide rod and deliver it to the stamping area. After stamping is completed, the turntable 31 rotates again, and the clamping mechanism 32 removes the finished product from the stamping area and releases it.

[0025] As a further embodiment of the present invention, the clamping mechanism 32 includes a fixed plate 321 and a telescopic plate 322. The telescopic plate 322 is elastically telescopically disposed on the side of the fixed plate 321 and slidably telescopically disposed on the fixed plate 321. A spring is provided between the telescopic plate 322 and the fixed plate 321 to form elastic telescopic movement. A plurality of rubber columns 323 are provided on the top surface of the fixed plate 321 away from the telescopic plate 322. The height of the telescopic plate 322 and the rubber columns 323 is higher than the height of the fixed plate 321. The sides of the rubber columns 323 near and away from the telescopic plate 322 are inclined surfaces. A clamping area for the metal sheet is formed between the telescopic plate 322 and the rubber columns 323.

[0026] The bottom of the storage box 1 is divided into two parts: the bottom of the storage box 1 on the scoop side is fully enclosed, while the bottom of the scoop handle section is exposed. The fixing plate 321, used to support the metal sheet, has a lower top surface, while the top surfaces of the telescopic plate 322 and the rubber column 323 are higher, forming a three-sided concave area. When the clamping mechanism 32 rotates to the position of the metal sheet, the edge of the scoop side of the metal sheet first contacts the telescopic plate 322; due to the elastic setting of the telescopic plate 322, it is slightly compressed by the metal sheet, thus generating a continuous elastic clamping force. The other edge of the metal sheet abuts against the inclined surface of the rubber column 323. The inclined surface design of the rubber column 323 allows the metal sheet to be automatically guided upon entry, preventing jamming. Finally, the metal sheet is stably clamped between the telescopic plate 322 and the rubber column 323, while the fixing plate 321 supports the bottom of the scoop side of the metal sheet from below.

[0027] The elastic telescopic plate 322 provides adaptive clamping force, accommodating minor fluctuations in the width of the metal sheet due to processing errors, preventing over-positioning or insufficient clamping. The inclined surface of the rubber column 323 has a guiding function, allowing the metal sheet to smoothly enter the clamping area, while the rubber material will not scratch the surface of the metal sheet. The height of the telescopic plate 322 and the rubber column 323 is higher than that of the fixed plate 321, ensuring that the metal sheet will not come out from above during feeding, improving feeding stability.

[0028] As a further embodiment of the present invention, the stamping assembly includes a stamping table, an upper die 42, and a lower die 43. A hydraulic rod 41 is disposed on the stamping table, the upper die 42 is disposed at the bottom of the hydraulic rod 41, and the lower die 43 is disposed on the stamping table. The lower die 43 is a hemispherical convex structure adapted to the inner side of the metal sheet spoon section, and the upper die 42 is a hemispherical concave structure adapted to the outer side of the metal sheet spoon section. The stamping table forms an inclined surface downwards towards the storage box 1 based on the edge of the hemispherical convex structure.

[0029] The stamping table serves as the load-bearing base. The lower die 43 is fixedly mounted on the stamping table, and the upper die 42 is mounted on the telescopic end of the hydraulic rod 41. The hydraulic rod 41 is driven by the hydraulic system, causing the upper die 42 to reciprocate up and down. When the metal sheet is fed by the feeding assembly to directly above the lower die 43, the hydraulic rod 41 extends, and the upper die 42 presses down, pressing the shovel-shaped section of the metal sheet into the cavity of the lower die 43, causing it to undergo plastic deformation. After the hydraulic rod 41 returns, the upper die 42 lifts up, completing one stamping cycle.

[0030] The lower die 43 adopts a hemispherical outward convex structure, while the upper die 42 adopts a hemispherical inward concave structure. The gap between the two is equal to the thickness of the metal sheet. During stamping, the spoon-shaped section of the metal sheet is pressed by the upper die 42 onto the lower die 43, gradually conforming from a flat surface to the hemispherical surface of the lower die 43, forming a three-dimensional arc surface. The stamping table has an inclined surface on the side near the storage box 1, which extends downward from the hemispherical edge of the lower die 43. When the spoon-shaped section of the metal sheet is stamped into an arc shape, the handle section will naturally tilt upward (because the spoon face and the handle are not on the same plane), but the presence of the inclined surface allows the handle section to bend downward, thus forming the angle between the handle and the spoon face required for the final product. After the upper die 42 and the lower die 43 stamp the metal sheet, as the handle section tilts downward, the force of the tilting deformation will cause the handle section to detach from the telescopic plate 322 and the rubber column 323. At the same time, the inclined surface also provides clearance space for the metal sheet during feeding and discharging.

[0031] The hemispherical mold has a simple structure, is easy to process, and is suitable for the common curved surfaces of tableware such as soup spoons. The inclined surface design causes the spoon handle to bend downwards passively during the stamping process, eliminating the need for secondary shaping. The three-dimensional forming of the spoon surface and handle can be completed in one stamping, improving production efficiency. The inclined surface is close to the side of the storage box 1, which facilitates the smooth transition of the metal sheet from the bottom of the storage box 1 to the stamping area during feeding.

[0032] As a further embodiment of the present invention, the hemispherical convex structure of the lower die 43 is provided with a limiting block 5 on the side away from the material storage component. The limiting block 5 abuts against and limits the metal sheet before stamping, and the limiting block 5 separates from the metal sheet after stamping.

[0033] The limiting block 5 is fixed to the side of the lower die 43, located at the front end in the feeding direction. When the feeding assembly rotates the metal sheet above the lower die 43, the front edge of the scoop section of the metal sheet contacts the limiting block 5, thus restricting the metal sheet from moving forward. At this time, the center of the scoop section of the metal sheet is precisely aligned with the hemispherical apex of the lower die 43, completing precise positioning before stamping. During stamping, the upper die 42 presses down, deforming the metal sheet. The scoop section of the metal sheet is concave downwards, and its front edge disengages from the limiting block 5 as it deforms. After stamping, the limiting block 5 no longer contacts the product, thus not obstructing the ejection. The limiting block 5 provides a mechanical hard limit, which, combined with the clamping force of the feeding assembly, ensures that each metal sheet is in the same precise position before stamping, without relying on sensors or vision systems. The limiting block 5 automatically separates during stamping, preventing scratches or deformation of the product.

[0034] As a further embodiment of the present invention, the storage box 1 is provided with a discharge port 6 on the side of the rotating feeding direction of the turntable 31, and the thickness of the discharge port 6 is less than the thickness of the two metal sheets.

[0035] A discharge port 6 is provided on the bottom side wall of the storage bin 1. The height (in the thickness direction) of the discharge port 6 is greater than the thickness of one metal sheet but less than the thickness of two metal sheets. Since the metal sheets are stacked inside the storage bin 1, the bottommost metal sheet contacts the lower edge of the discharge port 6 under gravity. When the feeding component pushes the bottommost metal sheet, it is pushed out of the discharge port 6; however, the second metal sheet above it is blocked inside the storage bin 1 because the height of the discharge port 6 is insufficient for it to pass through. After the bottommost metal sheet is completely pushed away, the second metal sheet falls to the bottom under gravity, becoming the new bottommost metal sheet. This achieves the goal of feeding only one metal sheet at a time, effectively avoiding the problem of multiple metal sheets being carried away by the clamping mechanism 32 or stuck in the discharge port 6 simultaneously. This structure is simple and reliable, requiring no complex separation mechanism.

[0036] As a further embodiment of the present invention, the guide rod includes a straight rod section 21 and a bent rod section 22. The bent rod section 22 extends laterally from the bottom of the storage box 1. The bottom of the bent rod section 22 is connected and fixed to the material collection device, and the top of the bent rod section 22 is detachably connected to the straight rod section 21.

[0037] The guide rod consists of an upper straight section 21 and a lower curved section 22. The straight section 21 passes vertically through a through-hole in the metal sheet, allowing the metal sheet to slide up and down along it. The curved section 22 extends laterally (i.e., in the opposite direction of feeding or discharging) from the bottom of the storage bin 1. When the metal sheet is pushed out of the bottom of the storage bin 1 by the feeding assembly, the through-hole on its handle section slides from the straight section 21 into the curved section 22. Because the curved section 22 is curved, as the metal sheet continues to be pushed, the through-hole moves along the trajectory of the curved section 22, causing the metal sheet to gradually tilt downwards while moving horizontally. The bottom of the curved section 22 is connected to a collection device (e.g., a collection box or conveyor belt). When the metal sheet is completely detached from the storage bin 1, it slides down the curved section 22 into the collection device. The straight section 21 and the curved section 22 are detachably connected (e.g., by threads or pins) to facilitate the replenishment of metal sheets into the storage bin 1 after disassembly.

[0038] As a further embodiment of the present invention, it also includes a control device and a sensor. The sensor is disposed on the limiting block 5. The control device is electrically connected to the sensor, the motor and the hydraulic rod 41. The control device commands the motor and the hydraulic rod 41 to operate according to the sensor data.

[0039] A sensor (such as a proximity switch or microswitch) is mounted on the limit block 5. When the feeding assembly pushes the metal sheet so that its edge contacts the limit block 5, the sensor detects the metal sheet's arrival signal and sends the signal to the control device (such as a PLC or microcontroller). Upon receiving the signal, the control device first instructs the motor to stop rotating, keeping the metal sheet in the stamping position; then it instructs the hydraulic rod 41 to extend and perform the stamping action. After stamping is completed, the control device, based on a preset delay or the return signal of the hydraulic rod 41, instructs the motor to restart for unloading and feeding in the next cycle. Simultaneously, the sensor can also be used to detect whether the metal sheet is indeed in place; if it is not, an alarm is triggered and the machine stops.

[0040] A forming method for processing metal tableware, applicable to a forming apparatus for processing metal tableware, includes the following steps: S1: The metal raw material is initially stamped to form a metal sheet with through holes in the handle section; S2: Fit the through hole of the metal sheet onto the straight rod section 21 of the guide rod, and stack it into the storage box 1; S3: The start control device commands the motor to rotate, and the turntable 31 starts to rotate under the drive of the motor. The inner side of the telescopic plate 322 on the turntable 31 abuts against one side of the metal sheet at the bottom of the storage box 1 and stretches under force, while the other side of the metal sheet abuts against the rubber column 323, so that the telescopic plate 322 and the rubber column 323 form a clamp on the metal sheet. The turntable 31 continues to rotate until the side of the metal sheet abuts against the limit block 5 and the sensor. At the same time, the control device commands the motor to stop. S4: After the control device obtains the sensor information, it instructs the hydraulic rod 41 to move and press the metal sheet, so that the spoon section of the metal sheet bends and separates from the limit block 5 and the sensor. At the same time, the handle section of the metal sheet is tilted downwards on the inclined surface of the stamping table along the bending direction of the spoon section, so that the through hole is transferred from the straight rod section 21 downwards to the bent rod section 22. S5: After the hydraulic cylinder completes the stamping action, the control device commands the motor to continue rotating. The clamping mechanism 32 pushes the metal sheet to separate from the lower die 43, so that the metal sheet slides down along the extension direction of the bent rod section 22 onto the collecting device for collection.

[0041] Working principle: First, the semi-finished metal sheet, which has undergone initial planar punching and has through holes in the handle section, is fitted onto the vertical guide rod section 21 inside the storage box 1 through the through holes. The fitting of the inner wall contour of the storage box 1 with the shape of the metal sheet achieves stacking and positioning. During operation, the control device instructs the motor to drive the turntable 31 to rotate. The clamping mechanism 32 fixed on the turntable 31 rotates with the turntable 31 to the bottom discharge port 6 of the storage box 1. Its elastic telescopic plate 322 abuts against one side of the metal sheet and generates clamping force. The inclined surface of the rubber column 323 on the other side automatically guides the metal sheet to form a stable clamp. The turntable 31 continues to rotate, and the clamping mechanism 32 pushes the bottom metal sheet out from the discharge port 6 with the guide rod as the rotation axis. It then rotates along the inclined surface of the stamping table to above the lower die 43 until the front end of the metal sheet contacts the limiting block 5 and sensor on the side of the lower die 43, achieving precise mechanical positioning. At this time, the control device instructs the motor to stop. Subsequently, based on the sensor's positioning signal, the control device instructs the hydraulic rod 41 to drive the upper die 42 downwards, cooperating with the hemispherical, convex lower die 43 to stamp the metal spoon face section into a three-dimensional arc surface. Simultaneously, the metal spoon handle section naturally bends downwards under the guidance of the inclined surface of the stamping table, forming a three-dimensional angle between the spoon face and the handle. The through-hole on the handle section transitions from the straight section 21 of the guide rod to the curved section 22. After stamping, the upper die 42 returns, and the control device again instructs the motor to rotate. The clamping mechanism 32 pushes the finished product away from the lower die 43, allowing it to automatically slide down along the extension direction of the curved section 22 of the guide rod into the collecting device, completing one work cycle. The entire process achieves fully automated continuous operation from stacking and storing materials, automatic material retrieval, rotating feeding, mechanical limiting, stamping, to automatic unloading, effectively avoiding positioning errors and material waste caused by manual placement with misalignment.

A forming method for processing metal tableware, applicable to a forming apparatus for processing metal tableware as described in any one of claims 1-9, characterized in that: Includes the following steps: S1: The metal raw material is initially stamped to form a metal sheet with through holes in the handle section; S2: Fit the through hole of the metal sheet onto the straight section of the guide rod and stack them into the storage box; S3: The start control device commands the motor to rotate. The turntable starts to rotate under the drive of the motor. The inner side of the telescopic plate on the turntable abuts against one side of the metal sheet at the bottom of the storage box and stretches under the force. The other side of the metal sheet abuts against the rubber column, so that the telescopic plate and the rubber column clamp the metal sheet. The turntable continues to rotate until the side of the metal sheet abuts against the limit block and the sensor. At the same time, the control device commands the motor to stop. S4: After the control device obtains the sensor information, it instructs the hydraulic rod to move and punch the metal sheet, so that the spoon section of the metal sheet bends and separates from the limit block and the sensor. At the same time, the handle section of the metal sheet is tilted downwards on the inclined surface of the stamping table along the bending direction of the spoon section, so that the through hole is transferred from the straight rod section to the bent rod section. S5: After the hydraulic cylinder completes the stamping action, the control device commands the motor to continue rotating, and the clamping mechanism pushes the metal sheet to separate from the lower die, so that the metal sheet slides down along the extension direction of the bent rod section to the collection device for collection.
