Description

Technical Field

[0001] This utility model relates to the field of parts processing technology, and in particular to a positioning and flipping device for stamping parts processing. Background Technology

[0002] Stamping is a manufacturing technology that uses the power of conventional or specialized stamping equipment to directly deform sheet metal within a die, thereby obtaining product parts with specific shapes, dimensions, and properties. Sheet metal, dies, and equipment are the three essential elements of stamping. Stamping is a cold deformation processing method for metals. Therefore, it is called cold stamping or sheet metal stamping, or simply stamping. It is one of the main methods of metal plastic forming (or pressure forming) and also belongs to materials forming engineering technology.

[0003] After stamping metal raw material sheets, due to the different shapes and positions of the stamped sheets, multiple stamping operations are required. To ensure that the metal raw material sheets are not severely deformed during stamping, they need to be flipped over for a second stamping operation to prevent deformation caused by continuous stamping on one side. To solve the above problems and ensure the stability of stamping processing, a positioning and flipping device for stamping parts processing is needed. Utility Model Content

[0004] The purpose of this invention is to solve the problem in the prior art that when stamping metal raw material sheets multiple times, it is necessary to flip them over for a second stamping operation to ensure that the metal raw material sheets are not severely deformed during stamping, thus preventing deformation caused by continuous stamping on one side of the metal raw material sheet. Therefore, this invention proposes a positioning and flipping device for stamping parts processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A positioning and flipping device for stamping parts processing includes a support processing table. A pair of load-bearing support plates are fixedly connected to the surface of the support processing table. A U-shaped plate is fixedly connected to the upper surface of the load-bearing support plates. A first extension plate and a second extension plate are fixedly connected to the surface of the support processing table. A drive shaft is rotatably connected to the inner wall of the first extension plate. A pair of first synchronous pulleys are fixedly connected to the surface of the drive shaft. A rotating shaft is rotatably connected to the inner wall of the second extension plate. A pair of second synchronous pulleys are fixedly connected to the surface of the rotating shaft. A synchronous belt is tensioned and sleeved on the surfaces of the first and second synchronous pulleys. A stamping flipping mechanism is provided on the upper surface of the support processing table.

[0007] Preferably, the stamping and flipping mechanism includes a hydraulic telescopic cylinder fixedly connected to the upper surface of the support processing table, a connecting plate fixedly connected to the output end of the hydraulic telescopic cylinder, a second stamping head and a first stamping head fixedly connected to the lower surface of the connecting plate, a timing belt installed inside the U-shaped plate, and a driving plate fixedly connected to the surface of the timing belt.

[0008] Furthermore, a spur gear is rotatably connected to the surface of the drive plate, and a placement plate is fixedly connected to one side of the spur gear. Multiple clearance holes are provided on both the upper and lower surfaces of the placement plate, and a metal raw material plate is detachably and slidably installed on the inner wall of the placement plate.

[0009] Preferably, a protective baffle is rotatably connected to the surface of the placement plate, the surface of the protective baffle is in close contact with the surface of the metal raw material plate, and a rack is fixedly connected to the surface of the load-bearing support plate, with the spur gear meshing with the rack.

[0010] Furthermore, an operation controller is fixedly connected to the surface of the support processing table, and multiple first support bars and second support bars are fixedly connected to the surface of the support processing table. A friction wheel is fixedly connected to one end of the drive shaft.

[0011] Preferably, a linkage plate is fixedly connected to the surface of the output end of the hydraulic telescopic cylinder, a guide plate is fixedly connected to the surface of the supporting processing table, the linkage plate is slidably connected to the inner wall of the guide plate, a motion plate is fixedly connected to the lower surface of the linkage plate, and a friction strip is fixedly connected to the surface of the motion plate.

[0012] Furthermore, a fixing plate is fixedly connected to the surface of the supporting processing table, a guide plate is fixedly connected to the upper surface of the fixing plate, a closed groove is opened on the surface of the guide plate, a vertical plate is fixedly connected to the inner wall of the closed groove, and the bottom surface of the vertical plate is set with a chamfer.

[0013] Preferably, a return spring is fixedly connected to the inner wall of the motion plate, and a guide shaft is fixedly connected to one end of the return spring. The diameter of the guide shaft is consistent with the width of the inner wall of the closed groove, and the guide shaft is slidably connected to the inner wall of the motion plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. During the stamping descent, the guide shaft moves along the arc of the closed groove under the obstruction of the top of the vertical plate. The friction strip never comes into contact with the surface of the friction wheel. At this time, the synchronous belt does not move, maintaining the stability of the stamping. When the first and second stamping heads rise, the chamfer transitions the upward movement of the guide shaft. The chamfer pushes one end of the guide shaft, causing it to rise vertically against the surface of the vertical plate. At this time, the surface of the friction strip comes into contact with the surface of the friction wheel, causing the friction wheel to rotate under force and friction, which in turn drives the synchronous belt to move, driving a pair of drive plates to move. When the spur gear moves and disengages from the surface of the rack, it drives the spur gear and the placement plate to rotate, facilitating flipping and re-stamping. The advantage of this is that it prevents the surface of the metal raw material plate from deforming after repeated stamping.

[0016] 2. The lower surfaces of the first and second stamping heads are at the same height and descend synchronously for stamping. When the metal raw material plate is flipped, the protective baffle limits the metal raw material plate placed in the placement plate to prevent the metal raw material plate from slipping out of the placement plate due to the rotation of the placement plate. The stamping is supported by a pair of load-bearing support plates and multiple first and second support bars. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Reference Figures 1-7 A positioning and flipping device for stamping parts processing includes a support processing table 1. A pair of load-bearing support plates 8 are fixedly connected to the surface of the support processing table 1. A U-shaped plate 3 is fixedly connected to the upper surface of the load-bearing support plates 8. A first extension plate 11 and a second extension plate 21 are fixedly connected to the surface of the support processing table 1. A drive shaft 16 is rotatably connected to the inner wall of the first extension plate 11. A pair of first synchronous pulleys 12 are fixedly connected to the surface of the drive shaft 16. A rotating shaft 34 is rotatably connected to the inner wall of the second extension plate 21. A pair of second synchronous pulleys 22 are fixedly connected to the surface of the rotating shaft 34. A synchronous belt 13 is tensioned and sleeved on the surfaces of the first synchronous pulleys 12 and the second synchronous pulleys 22. A stamping flipping mechanism is provided on the upper surface of the support processing table 1.

[0027] By setting a pair of load-bearing support plates 8, the U-shaped plate 3 is supported. By setting the U-shaped plate 3, the synchronous belt 13 is stored and protected. By setting the first extension plate 11 and the second extension plate 21, the rotation of the drive shaft 16 and the rotating shaft 34 is kept stable. By setting the drive shaft 16, the installation of a pair of first synchronous pulleys 12 is kept stable. By setting the rotating shaft 34, the installation of a pair of second synchronous pulleys 22 is kept stable. By setting the first synchronous pulleys 12 and the second synchronous pulleys 22, the tension of the synchronous belt 13 is kept stable. By setting a stamping flipping mechanism, the stamping operation is carried out. During the second stamping, the metal raw material plate 19 is flipped to prevent deformation caused by the first stamping.

[0028] In this utility model, reference Figure 1 and Figure 3The stamping and flipping mechanism includes a hydraulic telescopic cylinder 4 fixedly connected to the upper surface of the support processing table 1. A connecting plate 5 is fixedly connected to the output end of the hydraulic telescopic cylinder 4. A second stamping head 6 and a first stamping head 7 are fixedly connected to the lower surface of the connecting plate 5. A synchronous belt 13 is installed inside the U-shaped plate 3. A driving plate 23 is fixedly connected to the surface of the synchronous belt 13.

[0029] By setting up a hydraulic telescopic cylinder 4, the connecting plate 5 is driven to rise and fall in height. By setting up a second stamping head 6 and a first stamping head 7, the metal raw material plate 19 is stamped and shaped multiple times. By setting up a driving plate 23, the spur gear 33 and the placement plate 25 are driven to move.

[0030] In this utility model, reference Figure 3 and Figure 4 A spur gear 33 is connected to the surface of the drive plate 23 to rotate. A placement plate 25 is fixedly connected to one side of the spur gear 33. Multiple clearance holes 26 are provided on the upper and lower surfaces of the placement plate 25. A metal raw material plate 19 is detachably and slidably installed on the inner wall of the placement plate 25.

[0031] By setting a spur gear 33, when the spur gear 33 moves and contacts the surface of the rack 24, it drives the spur gear 33 and the placement plate 25 to rotate 180 degrees as a whole, realizing the flipping operation. By setting multiple clearance holes 26, the support of multiple first support bars 20 and second support bars 36 is spatially cleared. By setting a metal raw material plate 19, the shaping operation is completed after the stamping operation.

[0032] In this utility model, reference Figure 3 , Figure 4 and Figure 7 A protective baffle 35 is rotatably connected to the surface of the placement plate 25. The surface of the protective baffle 35 is in contact with the surface of the metal raw material plate 19. A rack 24 is fixedly connected to the surface of the load-bearing support plate 8. A spur gear 33 meshes with the rack 24.

[0033] By setting a protective baffle 35 to limit the metal raw material plate 19 placed inside the placement plate 25, the metal raw material plate 19 is prevented from sliding out of the placement plate 25 by rotating the placement plate 25.

[0034] In this utility model, reference Figure 1 and Figure 5 An operation controller 2 is fixedly connected to the surface of the support processing table 1. Multiple first support bars 20 and second support bars 36 are fixedly connected to the surface of the support processing table 1. A friction wheel 17 is fixedly connected to one end of the drive shaft 16.

[0035] By setting the operation controller 2, an electrical signal is sent to control the start and stop of the hydraulic telescopic cylinder 4. By setting multiple first support bars 20 and second support bars 36, bottom support is provided during the stamping operation of the metal raw material plate 19. By setting the friction wheel 17, it is driven to rotate by frictional cooperation with the friction bar 27.

[0036] In this utility model, reference Figure 5 A linkage plate 9 is fixedly connected to the surface of the output end of the hydraulic telescopic cylinder 4, a guide plate 18 is fixedly connected to the surface of the support processing table 1, the linkage plate 9 is slidably connected to the inner wall of the guide plate 18, a motion plate 10 is fixedly connected to the lower surface of the linkage plate 9, and a friction strip 27 is fixedly connected to the surface of the motion plate 10.

[0037] By setting the guide plate 18, the linkage plate 9 is kept stable in lifting and sliding. By setting the linkage plate 9, the motion plate 10 is installed and supported. By setting the motion plate 10, the friction strip 27 is driven to lift and lower. By setting the friction strip 27, when the surface of the friction strip 27 contacts the surface of the friction wheel 17, the friction wheel 17 is driven to rotate under the action of friction.

[0038] In this utility model, reference Figure 2 and Figure 6 A fixed plate 15 is fixedly connected to the surface of the support processing table 1. A guide plate 14 is fixedly connected to the upper surface of the fixed plate 15. A closed groove 30 is opened on the surface of the guide plate 14. A vertical plate 31 is fixedly connected to the inner wall of the closed groove 30. The bottom surface of the vertical plate 31 is set with a chamfer 32.

[0039] By setting a fixed plate 15 to support and fix the guide plate 14, and by setting a closed groove 30, the guide shaft 29 moves under the guidance of the closed groove 30. By setting a vertical plate 31, the guide shaft 29 is blocked from moving during its descent. By setting a chamfer 32, when the guide shaft 29 rises after descending to the lowest point in the closed groove 30, it avoids the movement and drives the guide shaft 29 to slide through the chamfer 32 to the surface position of the vertical plate 31. The advantage of doing this is that the guide plate 10 slides on the lower surface of the linkage plate 9.

[0040] In this utility model, reference Figure 5 and Figure 6 A return spring 28 is fixedly connected to the inner wall of the motion plate 10. A guide shaft 29 is fixedly connected to one end of the return spring 28. The diameter of the guide shaft 29 is consistent with the width of the inner wall of the closed groove 30. The guide shaft 29 is slidably connected to the inner wall of the motion plate 10.

[0041] By setting a reset spring 28, the guide shaft 29 is driven to reset. By setting the guide shaft 29, one end of the guide shaft 29 is always in contact with the inner wall of the closed groove 30.

[0042] Working principle: During use, the controller 2 sends an electrical signal to drive the output end of the hydraulic telescopic cylinder 4. The output end of the hydraulic telescopic cylinder 4 drives the connecting plate 5 to rise and fall. The connecting plate 5 drives the second stamping head 6 and the first stamping head 7 to rise and fall, performing stamping operations on the metal raw material plate 19. When the output end of the hydraulic telescopic cylinder 4 descends, it drives the linkage plate 9 and the moving plate 10 to descend together. During the descent of the moving plate 10, the guide shaft 29 installed on the moving plate 10 is blocked by the top of the vertical plate 31 and moves along... The arc movement of the closed groove 30, with the lower surfaces of the first stamping head 7 and the second stamping head 6 at the same height, completes the stamping of the metal raw material plate 19. At this time, the guide shaft 29 is located at the bottom of the closed groove 30. When the first stamping head 7 and the second stamping head 6 rise, the chamfer 32 transitions the upward movement of the guide shaft 29. The chamfer 32 pushes one end of the guide shaft 29, compressing the return spring 28, making it shorter, so that one end of the guide shaft 29 rises vertically against the surface of the vertical plate 31. At this time, the surface of the friction strip 27 is in contact with the friction... The friction wheel 17 contacts the surface, causing it to rotate under friction. The friction wheel 17 drives the drive shaft 16 to rotate, which in turn drives a pair of first synchronous pulleys 12 to rotate. The first synchronous pulleys 12 drive the synchronous belt 13 to move, which in turn drives the rotating shaft 34 to rotate. The rotating shaft 34 then drives a pair of second synchronous pulleys 22 to rotate. As the synchronous belt 13 moves, it drives a pair of driving plates 23 to move, which in turn drives the spur gear 33 to move against the placement plate 25. When the spur gear 33 moves, it disengages from the surface contact of the rack 24. The spur gear 33 and the placement plate 25 rotate 180 degrees. At this time, the protective baffle 35 limits the metal raw material plate 19 placed in the placement plate 25 to prevent the metal raw material plate 19 from slipping out of the placement plate 25 due to the rotation of the placement plate 25. The advantage of doing this is that after the metal raw material plate 19 is stamped by the first stamping head 7 under the support of the first support bar 20, it rotates and moves to multiple second support bars 36, where it is stamped by the second stamping head 6 for the next stamping operation, achieving the effect of flipping stamping to shape products of different shapes.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
