[0002] In stamping processing, sheet materials are the most widely used. Sheet materials are classified by thickness into thin plates, medium plates, thick plates, and extra-thick plates. According to the size of the material thickness t, it is divided into: ① t>4mm, called thick plates; ② t=1~4mm, called medium-thick plates; ③ t<1mm, called thin plates; ④ t≤0.2mm, called extremely thin materials or ultra-thin materials. For particularly thin materials, some are called foil materials, such as aluminum foil, tin foil, etc.

[0003] At present, due to the thickness of the sheet material, the sheet material will bend, and the bent part will be punched during the stamping of the pressure block.

One end of the rotating shaft 42 passes through and supports a first supporting plate 43, and the other end of the rotating shaft 42 passes through and supports a second supporting plate 431. A first conveying roller 44 is sleeved on the middle outer side of the rotating shaft 42. The first conveying roller 44 is matched with a second conveying roller 45 for rolling conveying. The inside of the second conveying roller 45 is connected to a rolling groove 451 opened on one side of the upper end surface of the support platform 1 through a first fixing rod; the opposite surfaces of the first conveying roller 44 and the second conveying roller 45 are conveyed and transmitted to the thin plate 14. The thin plate 14 is transported outward by the conveying device, and then transported to the inside of the conveying track 15 by the first conveying roller 44 and the second conveying roller 45. The power for the rolling of the first conveying roller 44 and the second conveying roller 45 is driven by the starting motor 4 to drive the rotating shaft 42 to rotate clockwise in the rotating holes of the first supporting plate 43 and the second supporting plate 431. The rotating shaft 42 is driven by the force of the first conveying roller 44 to rotate clockwise, and the first conveying roller 44 drives the thin plate 14 to move to one side in a clockwise manner. The thin plate 14 is driven by the force of the second conveying roller 45 on the lower surface to rotate counterclockwise, thereby making the thin plate 14 move smoothly to one side.

[0043] In this embodiment, the stamping mechanism 2 includes a hydraulic cylinder 21 fixedly connected to the middle of the upper wall of the support plate 11, the output end of the hydraulic cylinder 21 is connected to a pressure rod 22, the lower end surface of the pressure rod 22 is fixedly connected to a stamping block 23, both sides of the stamping block 23 are provided with guide holes 24, the guide holes 24 are slidably fitted with guide rods 25, the lower ends of the guide rods 25 are fixedly connected to both sides of the upper end surface of the support platform 1, and the two guide rods 25 are located on both sides of the width of the conveying track 15 , and the lower end surface of the pressing plate on the guide rod 25 is fixedly connected with a first spring body 26, and the lower end surface of the first spring body 26 is fixedly connected to one side of the upper end surface of the punching block 23. The lower end surface of the punching block 23 is fixedly connected with a punch 27 on both sides. The lower end surface of the punch 27 has a punching hole 271 opposite to each other. The punching hole 271 is opened in the middle of the conveying track 15, and the upper end of the punching hole 271 and the lower end surface of the punch 27 are punched on the upper surface of the thin plate 14. The hydraulic cylinder 21 is started to drive the pressing rod downward to drive the punching block 23 to move downward. When the punching block 23 moves downward, it slides downward on the outer side of the guide rod 25 using the guide hole 24, and stretches downward on the first spring body, so that the punching block 23 can be stably punched downward vertically.

[0044] In this embodiment, both sides of the punch block 23 are provided with a pressing groove 28 and an unfolding groove 29. The upper wall of the pressing groove 28 is provided with a sliding opening 281. A pressing plate 282 is slidably matched inside the sliding opening 281. The lower end of the pressing plate 282 is fixedly connected to a squeezing plate 283. The upper end surface of the squeezing plate 283 is equidistantly connected to a second spring body 284 along the length direction. The lower end surface of the pressing plate 282 is fixedly connected to a pressing block 285. The lower end surface of the pressing block 285 is pressed against the upper end surface of the thin plate 14. During the stretching of the round protrusion 2911, the pressing block 285 is used for pressure fixation, so that the stretched part of the thin plate 14 is effectively straightened into a straight line, avoiding the movement to the side where the thin plate 14 has been punched in the prior art. Furthermore, the thin plate 14 that has been punched on the upper part will not have a longer size, ensuring the qualified length of the thin plate 14, avoiding waste, improving functionality, improving practicality, and improving work efficiency.

[0045] In this embodiment, the unfolding groove 29 is rotatably matched with an unfolding plate 291 through a second fixed rod, a round protrusion 2911 is formed on the lower end surface of one side of the unfolding plate 291, and a rotation groove 2912 is provided on one side end surface of the unfolding plate 291, and the rotation groove 2912 is rotatably matched with a pressing roller 292 through a third fixed rod, and a transmission groove 2913 is provided on the upper end surface of the unfolding plate 291, and the transmission groove 2913 is rotatably matched with a transmission plate 293 through a fourth fixed rod, and one side of the transmission plate 293 is rotatably matched with a sliding plate 294 through a fifth fixed rod, and the sliding plate 294 is slidably matched with a push groove 2941, and the push groove 2941 is provided on the inner upper wall of the unfolding groove 29, and a third spring body 295 is fixedly connected to one side of the sliding plate 294, and the lower end of the third spring body 295 is fixedly connected to the inner side wall of the unfolding groove 29. The pressing roller 292 is first subjected to the pressure of the punching block 23, so that the pressing roller 292 first rolls on the upper end surface of the thin plate 14 and moves to one side, and the expansion plate 291 is subjected to the force and gradually rotates counterclockwise on the outside of the second fixing rod until the round protrusion 2911 on the expansion plate 291 presses against the upper end surface of the thin plate 14. At the same time, the lower end surface of the pressing block 285 has also pressed against the upper end surface of the thin plate 14, wherein the outer annular surface of the pressing roller 292 has been separated from the upper end surface of the thin plate 14, and then the punching block 23 continues to press, and the pressing block 285 is subjected to the resistance of the conveying track 15 and the thin plate 14, so that the pressing block 285 is driven upward by the extrusion plate 283 and the pressing plate 282 to move upward, and the pressing plate 282 is forced to slide upward inside the sliding opening 281, and the extrusion plate 283 is forced to press upward on the second spring body 284, so that the pressure of the pressing block 285 is tighter, wherein the round protrusion 2911 on the expansion plate 291 presses against the upper end surface of the thin plate 14 Block 2911 will follow the counterclockwise rotation of the unfolding plate 291, allowing the outer surface of the round protrusion 2911 to slide and rub to one side on the upper surface of the thin plate 14, so that the bent thin plate 14 is stretched into a straight line. During the continued stamping, the punch 27 at the lower end of the stamping block 23 stamps downward on the upper end surface of the thin plate 14, thereby completing the stamping work. At this time, the lower end of the punch 27 is located inside the stamping hole 271, and the lower end surface of the stamping block 23 is in a horizontal line with the lower end surface of the pressing block 285. The outer side surface of the round protrusion 2911 is in a horizontal line with the lower end surface of the stamping block 285, effectively stretching the bent thin plate 14 to one side and forming a straight line, so that the stamped part of the stamping part will not bend, thereby improving the accuracy of the roundness and diameter of the stamped hole, ensuring the aesthetics and qualified rate of the hole, thereby reducing the production of defective products and avoiding waste of thin plates 14.

[0046] When the punching block 23 moves upward, the expansion plate 291 rotates downward clockwise on the outside of the second fixed rod through the rebound force of the third spring body 295, gradually allowing the pressing roller 292 to press against the upper end surface of the thin plate 14, effectively allowing the side of the thin plate 14 that has been tightened by the clamping rod 333 to continue to maintain a straight state, preventing it from being blocked on the outside of the pressing roller 292 due to large bending, and preventing the thin plate 14 from detaching from the inside of the conveying track 15 when conveying. This allows the punching block 23 to maintain smooth conveying during operation and improve practicality.

[0047] In this embodiment, the round protrusion 2911 is made of rubber material, and the outer side surface of the pressing roller 292 presses against the upper end surface of the thin plate 14. The rubber material of the thin plate 14 prevents the upper end surface of the thin plate 14 from being scratched.

[0048] In this embodiment, the tensioning mechanism 3 includes a fixed transmission rod 31 fixedly connected to a side wall of the lower part of the sliding plate 294, the transmission rod 31 is rotatably matched with a first connecting plate 32, the first connecting plate 32 is rotatably matched with a guide plate 33 through a sixth fixed rod, a side of the guide plate 33 is fixedly connected to a sliding block 34, the sliding block 34 is slidably matched with a guide channel shell 35, and a fourth spring body 36 is fixedly connected between the inner wall of the guide channel shell 35 and a side of the sliding block 34. As the unfolding plate 291 gradually rotates upward counterclockwise, the transmission plate 293 is transmitted upward through the fourth fixed rod on the transmission groove 2913. The transmission plate 293 is driven to one side by the sliding plate 294 under the force. The sliding plate 294 is forced to slide to one side in the pushing groove 2941 and is stretched to one side by the third spring body 295. The sliding plate 294 moves to one side and drives the transmission rod 31. The transmission rod 31 is forced to be transmitted to one side by the first connecting plate 32. The first connecting plate 32 is forced to be transmitted to one side by the guide plate 33, so that the guide plate 33 slides to one side inside the guide channel housing 35 through the sliding block 34 and is obliquely pressed downward by the fourth spring body 36, so that the guide plate 33 can move downward stably.

[0049] In this embodiment, a pressure rod 331 is fixedly connected to one side of the guide plate 33, and a second connecting plate 332 is fixedly connected to the outer side of the pressure rod 331 at equal intervals along the length direction. A clamping rod 333 is fixedly connected to one side of the second connecting plate 332. The clamping rod 333 is connected to a clamping rod 335 through connecting blocks 334 at both ends. The clamping rod 333 and the clamping rod 335 are relatively transported to pass through the thin plate 14. Due to the inclination of the guide channel housing 35, the first connecting plate 32 and the guide plate 33 can adjust and rotate by themselves, so that the guide plate 33 can smoothly drive the pressing rod 331, the second connecting plate 332, the clamping rod 333, the connecting block 334, and the clamping rod 335 to move to one side, wherein the clamping rod 333 is tightened to one side on the upper surface of the thin plate 14 by the cooperation of the clamping rod 333 and the clamping rod 335, so that the side that has passed the stretching of the round protrusion 2911 will cause the thin plate 14 to come out The larger curvature is formed by tightening the clamping rod 333 to make the larger curvature become straight. The motor 4 has stopped running and has no self-locking function. After the round protrusion 2911 stretches the thin plate 14, the clamping rod 333 is tightened to make the larger curvature of the thin plate 14 gradually become straight. In the next conveying, the straight and smooth conveying is guaranteed to prevent the larger curvature from affecting the stamping work and the continuous bending from affecting the progress of the work conveying.

[0050] In this embodiment, the inner wall of the conveying track 15 is fixedly connected with the first guide block 5 and the second guide block 51 at equal intervals along the length direction. The two first guide blocks 51 guide the two sides of the thin plate 14 relative to each other, and the two second guide blocks 52 guide the two sides of the thin plate 14 relative to each other, so that the punched side and the unpunched side can continue to be conveyed in a straight and horizontal manner.

[0051] A method for using a thin plate automated stamping device, the specific method steps are as follows:

[0052] S1, first conveying: conveying the rolled thin plate 14 outwardly through the conveying device;

[0053] S2, second conveying: through the power of the motor 4, the first conveying roller 44 drives the thin plate 14 to move to one side in a clockwise direction, and the thin plate 14 is driven by the force to drive the second conveying roller 45 on the lower surface to rotate counterclockwise, thereby making the thin plate 14 move smoothly to one side;

[0054] S3, guiding: during the conveying of the thin plate 14, the first guide block 5 and the second guide block 51 are used to guide the punched side and the unpunched side to continue to be conveyed in a straight and horizontal manner, so as to avoid the phenomenon of outward deviation;

[0055] S4, stamping: the stamping block 23 is driven downward by the hydraulic cylinder 21, and the guide hole 24 slides downward on the outside of the guide rod 25 to ensure that the stamping block 23 moves vertically downward;

[0056] S5, fixing: When the punching block 23 continues to press, the pressing block 285 is resisted by the conveying track 15 and the thin plate 14, so that the pressing block 285 moves upward and presses upward on the second spring body 284, so that the pressure of the pressing block 285 is tighter, which can block the bending of one side of the thin plate 14 that has been punched, and avoid the movement to the side of the thin plate 14 that has been punched in the prior art, thereby ensuring the qualified length of the thin plate 14;

[0057] S6, stretching: by fixing the pressing block 23, the outer surface of the round protrusion 2911 is rubbed and slid to one side and stretched on the upper surface of the thin plate 14, so that the curved thin plate 14 can be stretched into a straight line, thereby improving the roundness and diameter accuracy of the punched hole, ensuring the aesthetics and qualified rate of the hole;

[0058] S7, punching: As the punching block 23 continues to punch, the punch 27 at the lower end of the punching block 23 punches downward on the upper end surface of the thin plate 14. At this time, the lower end of the punch 27 gradually presses against the upper end surface of the thin plate 14 until the punch 27 punches into the inside of the punching hole 271, thereby completing the punching work.

[0059] S8, tightening: The power of the transmission groove 2913 is transmitted to the transmission plate 293, so that the power of the transmission plate 293 is transmitted to the guide plate 33. The sliding block 34 slides to one side inside the guide channel shell 35, so that the guide plate 33 can smoothly drive the clamping rod 333 to tighten the upper surface of the thin plate 14 to one side. After the round protrusion 2911 stretches the thin plate 14, the clamping rod 333 is effectively tightened, so that the larger curve of the thin plate 14 gradually becomes a straight line.

[0060] The specific working principle of the present invention includes the following process:

[0061] First, the thin plate 14 is transported outward through the conveying device, and then the motor 4 is started to start the conveying of the first conveying roller 44 and the second conveying roller 45 to transport the thin plate 14 to the inside of the conveying track 15. When the thin plate 14 moves to one side, in order to prevent the thin plate 14 from deviating outward, a first guide block 5 and a second guide block 51 are provided. When the thin plate 14 continues to move, the guide surfaces on the two first guide blocks 5 are used to guide the deviated thin plate 14 to be transported in a straight line and horizontally. In order to prevent one side of the stamped sheet material from deviating outward, the guide surfaces on the two second guide blocks are used to guide the deviated thin plate 14 to continue to be transported in a straight line and horizontally.

[0062] When the thin material 14 needs to be punched, the hydraulic cylinder 21 is first started to drive the pressing rod 22 downward to drive the punching block 23 to move downward. The punching block 23 slides downward on the guide rod 25 using the guide hole 24 and is stretched downward on the first spring body. When the punching block 23 punches downward, the pressing roller 292 is first subjected to the pressure of the punching block 23, so that the pressing roller 292 rolls to one side on the upper end surface of the thin plate 14, and the unfolding plate 291 gradually rotates upward counterclockwise (before working, the pressing roller 292 is pressed on the upper end surface of the thin plate 14, such as Figure 4 As shown in the figure, until the round protrusion 2911 presses against the upper end surface of the thin plate 14, at the same time, the pressing block 285 has pressed against the thin plate 14, wherein the pressing roller 292 is separated from the upper end surface of the thin plate 14, and the pressing block 23 continues to press, the pressing block 285 is resisted by the conveying track 15 and the thin plate 14, so that the extrusion plate 283 and the pressing plate 282 move upward, and the pressing plate 282 slides upward inside the sliding opening 281, and the extrusion plate 283 and the pressing plate 282 move upward. 83 presses upward on the second spring body 284, which can make the pressure of the pressing block 285 tighter. Among them, when the round protrusion 2911 rotates counterclockwise with the power of the unfolding plate 291, the outer surface of the round protrusion 2911 rubs and slides to one side to stretch on the upper surface of the thin plate 14, so that the curved thin plate 14 is stretched into a straight line. During the continued stamping, the punch 27 at the lower end of the stamping block 23 stamps downward on the thin plate 14, thereby completing the stamping work.

[0063] As the unfolding plate 291 gradually rotates upward counterclockwise, the transmission plate 293 is transmitted upward through the fourth fixing rod on the transmission groove 2913, and the transmission plate 293 drives the sliding plate 294 outward, so that the sliding plate 294 slides to one side in the pushing groove 2941 and stretches on the third spring body 295. The power of the sliding plate 294 is transmitted to the transmission rod 31, the first connecting plate 32, the guide plate 33, and the sliding block 34. The sliding block 34 slides to one side on the guide channel housing 35 and is pressed on the fourth spring body 36. Due to the inclination of the guide channel housing 35, , allowing the guide plate 33 to smoothly drive the pressure rod 331, the second connecting plate 332, the clamping rod 333, the connecting block 334, and the clamping rod 335 to move to one side, wherein the clamping rod 333 and the clamping rod 335 cooperate to allow the clamping rod 333 to be tightened to one side on the upper surface of the thin plate 14, so that the side that has passed the stretching of the round protrusion 2911 will cause the thin plate 14 to have a larger curvature, and the tightening of the clamping rod 333 will make the larger curvature appear in a straight line, wherein the motor 4 has stopped running, and the motor 4 has no self-locking function.
