Description

Technical Field

[0001] This invention relates to the field of stamping die technology, and more particularly to a stamping die that is easy to guide. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] For example, patent (CN110394398A) discloses a stamping die for parts production, including multiple inspection plates, a shell, a blanking structure, an electric hydraulic cylinder, a stamping structure, a transmission structure, a flattening structure, a guiding structure, and a cutting structure. The stamping structure is connected to the electric hydraulic cylinder, which facilitates the gradual stamping of copper plates by driving the stamping structure through the electric hydraulic cylinder, thereby effectively preventing damage to the copper plates during the stamping process. At the same time, after the stamping is completed, the stamped parts can be easily separated from the stamping structure by using extrusion pressure, thereby greatly improving the stamping quality and efficiency. The shell has a flattening structure inside, which facilitates the flattening of copper plates. At the same time, the transmission structure is connected to the flattening structure, thereby synchronizing the flattening and stamping. The guiding structure is fixed to the shell, which facilitates the guidance of copper plates of different thicknesses and widths, avoiding copper plate misalignment and affecting the production and processing quality of copper plates.

[0004] When using the above technology, the following technical problems were found in the existing technology: the existing stamping die is not convenient for guiding and moving raw materials during use.

[0018] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0019] Meanwhile, through the above technical solutions, the present invention has at least the following beneficial effects:

[0020] The present invention provides a stamping die that is easy to guide. Through the cooperation of a support platform, an auxiliary plate, an inclined discharge groove and a guide moving mechanism, the lowering of the fixed plate drives the stamping and bending forming head and the blanking column to descend. The stamping and bending forming head stamps and bends the workpiece, while the blanking column blanks the bent workpiece, thus completing the two steps at the same time. The guide moving mechanism moves the stamped and bent workpiece to the bottom of the blanking column.

[0021] With the cooperation of the auxiliary plate, the return spring and the positioning plate, the workpiece between the two limit plates can move on the top of the support platform with the support of the auxiliary plate. When bending, the rebound of the compressed return spring will drive the bent workpiece to rise. At the same time, the movement of the workpiece is positioned by the positioning plate.

[0022] The guide rod moves between the two stroke adjustment shells through the cooperation of the stroke adjustment shell, guide rod, guide groove and guide plate. At the same time, the guide rod moves by pressing and guiding the workpiece on the top of the support table through the cooperation of the guide groove and guide plate, so as to facilitate the electric movement of the workpiece.

[0023] The displacement plate, synchronizing block, adjusting plate, first release plate, and second release plate are used to move the adjusting plate, which in turn causes the displacement plate to slide horizontally on the outside of the guide post. At the same time, the displacement plate drives the guide rod to move between the guide groove and the guide plate through the synchronizing block. This allows the guide rod to move the workpiece, and the displacement plate can be reset during movement, thus intermittently driving the guide rod to reciprocate. Attached Figure Description

[0041] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0042] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0043] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0044] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0045] Example 1

[0046] Reference Figures 1-5A stamping die for easy guidance includes a support platform 1. Limiting plates 10 are fixed on both sides of the top of the support platform 1, thereby limiting the position of the stamping workpiece on both sides through the limiting plates 10. A support frame 5 is fixed on the top of the support platform 1. A hydraulic cylinder 6 is fixed on the top of the inner side of the support frame 5. A fixing plate 7 is fixed on the push rod of the hydraulic cylinder 6. A stamping bending head 8 is fixed on one end of the bottom of the fixing plate 7, and a blanking column 9 is fixed on the other end of the bottom of the fixing plate 7. Thus, the movement of the hydraulic cylinder 6 can drive the stamping bending head 8 and the blanking column 9 to rise and fall simultaneously through the fixing plate 7, thereby completing two processes in the same station. A collection rack 2 is fixed on one end of the support platform 1. A finished product collection box 3 is provided on one end of the collection rack 2, so that the workpiece processed on the top of the support platform 1 can slide into the inner side of the finished product collection box 3 through the collection rack 2.

[0047] An auxiliary plate 11 is slidably connected inside the top of the support platform 1 and at a position corresponding to the stamping and bending forming head 8. This allows the auxiliary plate 11 to descend when the stamping and bending forming head 8 stamps and bends the workpiece. Return springs 12 are fixed at the bottom of both sides of the auxiliary plate 11 and inside the support platform 1. The descent of the auxiliary plate 11 causes the return springs 12 to compress. The return springs 12 then rebound after compression, causing the auxiliary plate 11, which is not under external pressure, to rise. At the same time, return springs 12 with different rigidities can be replaced according to the different pressures of the hydraulic cylinder 6.

[0048] A punching hole 13 is provided inside the top of the support platform 1 and at the position corresponding to the punching column 9, so that when the punching column 9 descends to punch the bent workpiece, it enters the interior of the punching hole 13. An inclined discharge groove 14 is provided inside the support platform 1 and at the bottom of the punching hole 13. A stamping part collection box 4 is fixed on one side of the support platform 1 and at the position corresponding to the inclined discharge groove 14, so that the circular waste parts that fall off during punching can be collected through the stamping part collection box 4.

[0049] Positioning plates 16 are slidably connected inside the support platform 1 at one end of the auxiliary plate 11 and one end of the punching hole 13. One of the positioning plates 16 limits the workpiece at the top of the auxiliary plate 11, and the other positioning plate 16 positions the bent workpiece. A lifting plate 15 is slidably connected inside the bottom of the support platform 1. The top of the lifting plate 15 is fixed to the positioning plate 16, so that the descent of the lifting plate 15 causes the two positioning plates 16 to descend simultaneously. A first compression spring 17 is fixed at both ends of the bottom of the lifting plate 15 inside the support platform 1. A push rod motor 18 is fixed inside the bottom of the support platform 1. The push rod of the push rod motor 18 is fixed to the lifting plate 15, so that the operation of the push rod motor 18 drives the lifting plate 15 to rise and fall.

[0050] In other embodiments, an infrared rangefinder can be fixed to the bottom of the fixed plate 7, and then, with the cooperation of the infrared rangefinder, the rising of the fixed plate 7 can drive the positioning plate 16 to descend.

[0051] The following is the usage process of a stamping die that facilitates guidance, provided by this invention: During use, the workpiece initially being processed is moved from the top of the support platform 1 to the top of the auxiliary plate 11 via the wires of the two limiting plates 10. Then, the hydraulic cylinder 6 drives the fixed plate 7 to descend, causing the stamping bending head 8 and the blanking column 9 to descend. At this time, the stamping bending head 8 contacts the workpiece at the top of the auxiliary plate 11, causing the workpiece to bend. Simultaneously, the descent of the workpiece during bending causes the auxiliary plate 11 to descend and compress the return spring 12. Then, the hydraulic cylinder 6 drives the fixed plate 7 to rise. At this time, the push rod motor 18 is energized, causing the lifting plate 15 to descend. The descent of the lifting plate 15 causes the positioning plate 16 to descend. Then, the bent workpiece is moved to the position corresponding to the blanking column 9, while simultaneously... A new workpiece enters the top of the auxiliary plate 11, and at the same time, the push rod motor 18 drives the lifting plate 15 to rise, which in turn drives the positioning plate 16 to rise. The positioning plate 16 positions the workpiece, and then the fixing plate 7 drives the stamping and bending forming head 8 and the blanking column 9 to descend. The stamping and bending forming head 8 stamps and bends the new workpiece, and the blanking column 9 punches holes in the bent workpiece. The waste parts that fall after punching enter the interior of the inclined discharge chute 14 through the blanking hole 13, and the waste parts inside the inclined discharge chute 14 enter the interior of the stamping part collection box 4 for collection. At the same time, after the positioning plate 16 descends, the bent workpiece moves and squeezes the punched workpiece, so that the punched workpiece slides into the interior of the finished product collection box 3 through the collection rack 2. At this time, the bent workpiece becomes a new punched workpiece.

[0052] Example 2

[0053] Reference Figures 6-15A stamping die for easy guidance includes a support platform 1 with stroke adjustment housings 19 fixed on both sides. Guide grooves 21 are formed on both sides of the interior of each stroke adjustment housing 19. Guide rods 20 are slidably connected to the inner sides of the guide grooves 21, allowing the guide rods 20 to translate through the two stroke adjustment housings 19. The movement of the guide rods 20 guides the bent workpiece to the punching position at the top of the limiting plate 10. A guiding mechanism for moving the guide rods 20 is installed inside the stroke adjustment housings 19. The moving mechanism includes a guide post 23, a tension spring 24, a displacement plate 25, a synchronizing block 26, a closing plate 27, a second compression spring 28, a lifting slide plate 29, and a first disengagement plate 39. The bottom end of the displacement plate 25 is slidably connected to the guide post 23. The guide post 23 is fixed to the stroke adjustment shell 19, so that the displacement plate 25 slides on the outside of the guide post 23, resulting in translational movement. A tension spring 24 is fixed between the displacement plate 25 and the stroke adjustment shell 19 and on the outside of the guide post 23, so that when the displacement plate 25 moves, it drives the tension spring 24 to be stretched.

[0054] A lifting slide plate 29 is slidably connected to the inner side of the displacement plate 25, so that the lifting slide plate 29 can only slide up and down inside the displacement plate 25. Synchronizing blocks 26 are fixed on both sides of the outer side of the lifting slide plate 29. The synchronizing blocks 26 are L-shaped. A first pressing slope is opened at one end of the top of the synchronizing block 26. When the synchronizing block 26 is reset, the synchronizing block 26 contacts the guide rod 20 through the first pressing slope, which drives the guide rod 20 to rise. Thus, when the displacement plate 25 contacts the guide rod 20, the guide rod 20 enters the position between the displacement plate 25 and one end of the synchronizing block 26. In this way, the movement of the displacement plate 25 drives the guide rod 20 to move synchronously through the synchronizing block 26.

[0055] A second compression spring 28 is fixed to the bottom of the synchronizing block 26, so that the synchronizing block 26 drives the second compression spring 28 to compress according to the descent of the lifting slide plate 29. A first release plate 39 is fixed to one end inside the stroke adjustment shell 19. A second release slope 41 is opened at the bottom of the first release plate 39 near the end of the synchronizing block 26, so that when the second release slope 41 contacts the lifting slide plate 29, the lifting slide plate 29 descends inside the displacement plate 25 due to the inclination of the second release slope 41. A first release slope 40 is opened at the top of the first release plate 39 near the end of the synchronizing block 26, so that the first release slope 40 contacts the guide rod 20, causing the guide rod 20 to rise between the displacement plate 25 and the synchronizing block 26. Then, through the rise of the guide rod 20 and the descent of the synchronizing block 26, the guide rod 20 is released from the limit of the synchronizing block 26. A closing plate 27 is fixed between one end of the two synchronizing blocks 26, which can restrict the movement of the first release plate 39 inside the displacement plate 25.

[0056] The interior of the stroke adjustment housing 19 is equipped with a reciprocating adjustment mechanism for driving the displacement plate 25 to move horizontally. The reciprocating adjustment mechanism includes a displacement drive motor 31, a first gear 32, a second gear 33, a rotating shaft 34, a threaded section 35, an adjustment plate 36, a positioning block 37, a third compression spring 38, and a second release plate 42. The rotating shaft 34 is rotatably connected to the bottom of the interior of the stroke adjustment housing 19. The displacement drive motor 31 is fixed to one end of the bottom of the interior of the stroke adjustment housing 19. The output end of the displacement drive motor 31 is connected to the first gear 32. The top of the first gear 32 is meshed with the second gear 33. The interior of the second gear 33 is fixed to the rotating shaft 34, so that the rotation of the second gear 33 drives the rotating shaft 34 to rotate synchronously. A threaded section 35 is opened on the outer side of the rotating shaft 34. The adjusting plate 36 is threadedly connected to the outer side of the threaded section 35. The adjusting plate 36 is slidably connected to the stroke adjustment housing 19, so that the adjusting plate 36 can only move horizontally inside the stroke adjustment housing 19.

[0057] A positioning block 37 is slidably connected to the top of the adjusting plate 36. The top of the positioning block 37 near the displacement drive motor 31 has a second pressing slope. When the adjusting plate 36 moves towards the displacement drive motor 31, the positioning block 37 contacts the displacement plate 25 through the second pressing slope, forming a pressing force, so that the positioning block 37 completely enters the interior of the adjusting plate 36. The bottom sides of the positioning block 37 and inside the adjusting plate 36 are fixed with third compression springs 38. The descent of the positioning block 37 causes the third compression springs 38 to compress. At the same time, the rebound of the third compression springs 38 after compression causes the positioning block 37, which is not compressed by external force, to rise.

[0058] A second release plate 42 is fixed inside the stroke adjustment housing 19 at the end away from the displacement drive motor 31 and at the position corresponding to the positioning block 37. The second release plate 42 is slidably connected to the displacement plate 25, so that the second release plate 42 can enter the inner side of the displacement plate 25. A rectangular groove 30 is opened inside the displacement plate 25 at the position corresponding to the second release plate 42. The second release plate 42 and the displacement plate 25 are slidably connected through the rectangular groove 30. A third release slope 43 is opened at the bottom of the second release plate 42 near the displacement drive motor 31, so that the adjustment plate 36 drives the displacement plate 25 to move. When the rectangular groove 30 on the displacement plate 25 is located outside the second release plate 42, the second release plate 42 presses the positioning block 37 through the third release slope 43, so that the positioning block 37 descends and drives the third compression spring 38 to compress. Then, the displacement plate 25 is reset by the rebound after being stretched by the tension spring 24 after being squeezed by external force.

[0059] Inside the stroke adjustment housing 19, on the side away from the support platform 1 and inside the guide groove 21, a guide plate 22 is fixed, allowing the guide rod 20 to move between the guide groove 21 and the guide plate 22. The guide rod 20 moves the workpiece between the bottom of the guide plate 22 and the guide groove 21, and resets between the top of the guide plate 22 and the guide groove 21. The guide groove 21 consists of a first connecting plane 44, a first inclined surface 45, a second connecting plane 46, a second inclined surface 47, a third connecting plane 48, and a fourth connecting plane 49. One end of the first connecting plane 44 is connected to the first inclined surface 45, one end of the first inclined surface 45 is connected to the second connecting plane 46, and the top of the second connecting plane 46 is connected to the second inclined surface 47. This allows the guide rod 20 to move between the first inclined surface 45 and the second connecting plane 49. The guide rod 20 is positioned between the first inclined surface 46 and the second inclined surface 47. At this time, the bottom of the guide rod 20 is higher than the top of the workpiece. When the guide rod 20 has passed through the first inclined surface 45 and entered the top of the first connecting surface 44 from the position inside the first inclined surface 45, the bottom of the guide rod 20 contacts the top of the limiting plate 10. The end of the second inclined surface 47 away from the second connecting surface 46 is connected to the third connecting surface 48, so that when the guide rod 20 moves from between the third connecting surface 48 and the guide plate 22 to between the second inclined surface 47 and the guide plate 22, the guide rod 20 is reset by the inclination of the second inclined surface 47. The end of the third connecting surface 48 away from the second inclined surface 47 is connected to the fourth connecting surface 49, and the fourth connecting surface 49 is connected to the first connecting surface 44.

[0060] The guide plate 22 has a guide surface on its outer side, which is composed of a fifth connecting plane 50, a third inclined plane 51, a sixth connecting plane 52, and a fourth inclined plane 53. The guide plate 22 has a fifth connecting plane 50 on its top, and one end of the fifth connecting plane 50 is connected to the third inclined plane 51. This allows the guide rod 20 to enter between the guide rod 20 and the third connecting plane 48 when it is reset. The bottom of the third inclined plane 51 is connected to the sixth connecting plane 52, and the end of the sixth connecting plane 52 away from the third inclined plane 51 is connected to the fourth inclined plane 53. The fourth inclined plane 53 is connected to the fifth connecting plane 50, so that when the guide rod 20 needs to guide the bent workpiece when it moves between the first inclined plane 45, the second connecting plane 46, and the second inclined plane 47, the guide rod 20 enters between the first connecting plane 44 and the sixth connecting plane 52 through the position between the first inclined plane 45 and the fourth inclined plane 53.

[0061] The following is the usage process of a stamping die that facilitates guidance, provided by this invention: When the workpiece needs to be punched after stamping and bending, the positioning plate 16 is first lowered, and then the displacement drive motor 31 is energized to drive the first gear 32 to rotate. The rotation of the first gear 32 drives the meshing second gear 33 to rotate. The rotation of the second gear 33 drives the threaded section 35 to rotate through the rotating shaft 34. The rotation of the threaded section 35 drives the threaded adjustment plate 36 to move, which in turn drives the displacement plate 25 to move. The movement of the displacement plate 25 drives the inner guide rod through the synchronizing block 26. The guide rod 20 moves, allowing it to pass through the wires of the first inclined surface 45 and the fourth inclined surface 53 into the space between the first connecting plane 44 and the sixth connecting plane 52. At this point, the bottom of the guide rod 20 contacts the top of the limiting plate 10, causing the adjusting plate 36 to move the displacement plate 25. The displacement plate 25 then moves the guide rod 20 to move the bent workpiece to the punching station. When the guide rod 20 contacts the fourth connecting plane 49, the movement of the displacement plate 25 causes the tension spring 24 to stretch. At this point, the lifting slide plate 29 on the inner side of the displacement plate 25 contacts the second disengagement inclined surface 41, thereby allowing the second disengagement inclined surface 41 to move the workpiece to the punching station. The tilt of the first release plate 42 causes the lifting slide plate 29 to descend, driving the synchronous block 26 to descend. Simultaneously, the first release ramp 40 contacts the bottom of the guide rod 20, causing the guide rod 20 to rise. This raises the guide rod 20, aligning it with the fourth connecting plane 49 and the third tilt surface 51. Simultaneously, the third release ramp 43 at the bottom of the second release plate 42 presses against the positioning block 37, causing the positioning block 37 to descend and compress the third compression spring 38. This releases the positioning block 37 from the pressure on the displacement plate 25, allowing the displacement plate 25 to reset via the rebound of the tension spring 24. At the same time, the displacement plate 25... The reset movement causes the guide rod 20 to move between the third connecting plane 48 and the fifth connecting plane 50 through the inclination of the third inclined surface 51. The continued movement of the displacement plate 25 causes the guide rod 20 to reset to its initial position through the second inclined surface 47. Then, the rotating shaft 34 drives the threaded section 35 to rotate in the opposite direction, causing the threaded connecting adjusting plate 36 to reset. The reset movement of the adjusting plate 36 causes the positioning block 37, which is not squeezed by external force, to rise and reset. At the same time, when the second squeezing inclined surface on the positioning block 37 contacts the displacement plate 25, the squeezing causes the positioning block 37 to fall and the adjusting plate 36 to reset to its initial position, waiting for the next operation.
