Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to a fully automatic stamping device for automotive parts processing. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube and profile, causing plastic deformation or separation, thereby obtaining a workpiece (stamped part) of the required shape and size. During the stamping process, it is necessary to limit the product to be stamped. Existing automotive parts stamping equipment does not limit the product to be processed accurately enough.

[0003] In the prior art, such as Chinese patent CN115945569B which discloses "a stamping machine for automotive parts", the stamping device includes a stamping device, a feeding device connected to the stamping device for automatic feeding, and a storage device connected to the feeding device; the stamping device includes a placement frame with an installation area on the placement frame; the storage device includes a storage cavity for storing parts, and a connecting cavity is connected to the storage cavity; the feeding device includes a support cavity, and a rotating frame is intermittently rotatably connected to the support cavity; the rotating frame has multiple placement cavities corresponding to the installation area evenly arranged along its circumference, and a sliding rotating rod intermittently slides and rotates on the support cavity as the rotating frame rotates intermittently; a connecting frame is connected to the sliding rotating rod, and a feeding plate is connected to the connecting frame. The feeding plate is provided with a suction cup, which can transfer the parts on the connecting cavity to the placement cavity by sliding and rotating with the sliding rotating rod.

[0004] However, in the existing technology, when using suction cups to fix the objects to be stamped, the suction cups cannot completely adsorb objects with uneven surfaces, and the fixing effect is not good for irregularly shaped objects.

In addition, the suction cups are not firm enough for fixing heavy parts, and cannot accurately fix small parts. To address the above problems, a fully automatic stamping device for automotive parts processing is proposed. Summary of the Invention

Furthermore, the first gear drives the other set of racks to move, thereby realizing that both sets of racks move towards the center position. By setting two sets of sliding rods, the two sets of sliding seats slide along the outer walls of the two sets of sliding rods.

[0029] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways than those described herein, and therefore the invention is not limited to the specific embodiments disclosed in the following specification. Example 1

[0031] like Figure 1-4As shown, the present invention provides a fully automatic stamping device for processing automotive parts, including a stamping mechanism 1. A clamping mechanism 3 is provided at the bottom of the stamping mechanism 1. The clamping mechanism 3 includes a support frame 31, a hydraulic cylinder 32 is provided at the bottom of the support frame 31, a connecting seat 33 is fixedly installed at the top of the hydraulic cylinder 32, two sets of sliding seats 34 are movably connected to the top of the support frame 31, the top of the connecting seat 33 is fixedly connected to the bottom of one set of sliding seats 34, clamping plates 35 are fixedly installed at the top of each set of sliding seats 34, and two sets of sliding rods 36 are provided at the top of the support frame 31. Connecting blocks 37 are fixedly connected to the outer walls of the two sets of sliding rods 36. A connecting column 38 is fixedly installed on the top of the connecting block 37, and a workbench 39 is fixedly installed on the top of the connecting column 38. A first gear 310 is movably connected to the outer wall of the connecting column 38. Two sets of racks 311 mesh with the outer wall of the first gear 310. A limit block 312 is fixedly installed at one end of each set of racks 311. The outer wall of the connecting seat 33 is provided through the top of the support frame 31. The outer walls of the two sets of sliding rods 36 are provided through one side of the two sets of sliding seats 34. The bottom of the two sets of limit blocks 312 is fixedly connected to the top of the two sets of sliding seats 34 respectively. The two sets of racks 311 are provided through one side of the two sets of limit blocks 312 respectively.

[0032] The specific settings and functions of this embodiment are described below. When the steel plate to be stamped moves to the top of the worktable 39, the hydraulic cylinder 32 first retracts, causing the connecting seat 33 to move towards the center position. Then, the connecting seat 33 drives a set of sliding seats 34 to move towards the center position. By setting a first gear 310 and two sets of racks 311, one set of sliding seats 34 drives one set of racks 311 to move towards the center position, thereby enabling the racks 311 to drive the first gear 310 to rotate. Furthermore, the first gear 310 drives the other set of racks 311 to move, thus enabling both sets of racks 311 to move towards the center position. The rack 311 drives another set of sliding seats 34 to move towards the center position. By setting two sets of sliding rods 36, the two sets of sliding seats 34 slide along the outer wall of the two sets of sliding rods 36. The two sets of sliding rods 36 limit and fix the two sets of sliding seats 34. By setting two sets of sliding seats 34 and two sets of clamping plates 35, the two sets of sliding seats 34 drive the two sets of clamping plates 35 to move towards the center position, thereby clamping the steel plate to be stamped. The stamping mechanism 1 is started to stamp the clamped steel plate, making the processing position of the steel plate more accurate, thereby avoiding the problem of poor stamping quality caused by local deformation of the steel plate. Example 2

[0033] like Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, a feeding mechanism 2 is provided on one side of the clamping mechanism 3. The feeding mechanism 2 includes a storage bin 21. A top cover 22 is movably connected to the top of the storage bin 21. Fixing bolts 23 are installed through the top of the top of the top cover 22 near the four corners. A connecting shell 24 is fixedly installed on the outer wall of the storage bin 21. A cam 25 is provided inside the connecting shell 24. A connecting rod 26 is fixedly installed on the top of the cam 25. A motor 27 is fixedly installed on the top of the connecting shell 24. A push plate 28 is provided inside the storage bin 21. Two sets of fixing rods 29 are fixedly installed at the bottom of the push plate 28. A movable rod 210 is rotatably connected to one end of each of the two sets of fixing rods 29. A connecting ring 211 is fixedly installed at one end of each of the two sets of movable rods 210. A through-hole is provided inside the two sets of connecting rings 211. There is a support rod 212, and a first spring 213 is provided on the outer wall of the support rod 212. Two sets of support columns 214 are fixedly installed at the bottom of the support rod 212. Two sets of second springs 215 are fixedly installed at the bottom of the push plate 28. Four sets of fixing bolts 23 are all installed through the top of the storage bin 21. The top of the connecting rod 26 is installed through the top of the connecting shell 24. The output end of the first motor 27 is fixedly connected to the top of the connecting rod 26. The two ends of the support rod 212 are fixedly connected to the inner walls of both sides of the storage bin 21. The two ends of the first spring 213 are fixedly connected to the outer walls of the two sets of connecting rings 211. The bottoms of the two sets of support columns 214 are fixedly connected to the inner walls of the storage bin 21. The bottoms of the two sets of second springs 215 are fixedly connected to the inner walls of the storage bin 21.

[0034] The effect achieved by the entire embodiment is that the workers first stack the iron plates to be stamped into the inside of the storage bin 21, and then cover it with the top cover 22. Then, they fix the four sets of fixing bolts 23, and then start the first motor 27. The first motor 27 drives the connecting rod 26 to rotate, and the connecting rod 26 further drives the cam 25 to rotate.

[0035] During the rotation of cam 25, whenever the tip reaches the outer wall of the iron plate, it pushes the iron plate to the right, thereby pushing the iron plate to be stamped onto the outer wall of a set of feeding rollers 413, realizing automatic feeding of the iron plate. Whenever a set of iron plates is pushed out of the storage bin 21, spring 213 extends, pushing the two sets of connecting rings 211 to move to both ends. The two sets of connecting rings 211 move to both ends along the support rod 212, and the two sets of movable rods 210 move at the top of the two sets of connecting rings 211. The two sets of movable rods 210 rotate at the top of the two sets of fixed rods 29. The two sets of movable rods 210 push the two sets of fixed rods 29 upward, and the two sets of fixed rods 29 push the push plate 28 upward. The two sets of second springs 215 extend. By setting the first spring 213 and the two sets of second springs 215, when the number of steel plates decreases, the push plate 28 will be pushed upward, thereby limiting the steel plates. In conjunction with the cam 25, the automatic feeding of steel plates is realized, improving the feeding efficiency. Example 3

[0036] like Figure 1 , Figure 2 and Figure 7 As shown, a conveying mechanism 4 is provided on one side of the clamping mechanism 3. The conveying mechanism 4 includes two sets of fixed frames 41. Two sets of fixed plates 42 are fixedly installed on the inner wall of one set of fixed frames 41. A second motor 43 is fixedly installed between the two sets of fixed plates 42. A second gear 44 is fixedly installed at the output end of the second motor 43. A third gear 45 meshes with the outer wall of the second gear 44. Rotating shafts 46 are movably connected to the inner walls of both sets of fixed frames 41. A fourth gear 47 meshes with the outer wall of the second gear 44. Rotating wheels 48 are fixedly installed on the outer walls of both sets of rotating shafts 46. The wall is movably connected to a first conveyor belt 49. The outer walls of two sets of rotating shafts 46 are fixedly mounted with driving wheels 410. The outer walls of the two sets of driving wheels 410 are movably connected to a second conveyor belt 411. The inner walls of the two sets of second conveyor belts 411 are movably connected to driven wheels 412. The inner walls of the two sets of fixed frames 41 are rotatably connected to three sets of feeding rollers 413. The bottom of the second gear 44 is in contact with the top of a set of fixed plates 42. The outer wall of a set of rotating shafts 46 is fixedly connected to one side of a fourth gear 47. The outer walls of the two sets of feeding rollers 413 are respectively fixedly connected to one side of the two sets of driven wheels 412.

[0037] The overall effect of this embodiment is that when the cam 25 pushes the steel plate out of the storage bin 21, the operator first starts the second motor 43, the second motor 43 drives the second gear 44 to rotate, the second gear 44 drives the third gear 45 to rotate, the third gear 45 drives a set of rotating shafts 46 to rotate, and by setting the first conveyor belt 49, the rotating shafts 46 drive a set of rotating wheels 48 to rotate, and the rotating wheels 48 drive the first conveyor belt 49 to rotate, thereby realizing the rotation of another set of rotating wheels 48.

[0038] Two sets of rotating wheels 48 rotate simultaneously, and another set of rotating wheels 48 drives the rotating shaft 46 to rotate. Both sets of rotating shafts 46 rotate, driving two sets of driving wheels 410 to rotate. The two sets of driving wheels 410 drive two sets of second-generation conveyor belts 411 to rotate. By setting two sets of driven wheels 412, the two sets of second-generation conveyor belts 411 drive the two sets of driven wheels 412 to rotate, and the two sets of driven wheels 412 drive the two sets of feeding rollers 413 to rotate, thereby realizing the conveying of steel plates. By setting two gears 44, three gears 45, and four gears 47, the convex teeth of the two gears 44 first drive the three gears 45 to rotate. After the three gears 45 are rotated at a certain angle, the two gears 44 continue to rotate, but they do not contact the three gears 45 and the four gears 47, so they do not drive them to rotate.

[0039] When the convex tooth of gear 44 rotates to the outer wall of gear 47, it drives gear 47 to rotate. During the rotation of gear 47, it drives the rotating shaft 46 to rotate, which in turn drives gear 3 to rotate. When the convex tooth of gear 44 rotates to the outer wall of gear 45, it drives gear 45 to rotate again. Since the convex tooth of gear 44 is constantly rotating, there are two periods in between when the convex tooth does not contact gear 45 or gear 47, thus achieving intermittent rotation of the rotating shaft 46. Therefore, the two sets of rotating wheels 48 and the two sets of driving wheels 410 are intermittently rotated, which in turn achieves intermittent rotation of the two sets of driven wheels 412, and consequently, intermittent rotation of the two sets of feeding rollers 413, which intermittently drives the steel plate to move.

[0040] The operation and working principle of this device are as follows: First, the operator stacks the iron plates to be stamped into the storage bin 21 and covers it with the top cover 22. Then, the four sets of fixing bolts 23 are fixed. Next, the first motor 27 is started. The first motor 27 drives the connecting rod 26 to rotate. The connecting rod 26 further drives the cam 25 to rotate. During the rotation of the cam 25, whenever the tip of the cam rotates to the outer wall of the iron plate, it will push the iron plate to the right, thereby pushing the iron plate to be stamped onto the outer wall of a set of feeding rollers 413, thus realizing the automatic feeding of the iron plate.

[0041] Whenever a set of iron plates is pushed out of the storage bin 21, spring 213 extends, pushing the two sets of connecting rings 211 to move to both ends. The two sets of connecting rings 211 move to both ends along the support rod 212. The two sets of movable rods 210 rotate at the top of the two sets of connecting rings 211, and the top of the two sets of movable rods 210 rotates at the bottom of the two sets of fixed rods 29. The two sets of movable rods 210 push the two sets of fixed rods 29 upward, and the two sets of fixed rods 29 push the push plate 28 upward. Springs 215 extend, pushing the push plate 28. Moving upwards, when cam 25 pushes the steel plate out of storage bin 21, the worker first starts motor 43. Motor 43 drives gear 44 to rotate, gear 44 drives gear 45 to rotate, gear 45 drives a set of rotating shafts 46 to rotate, rotating shafts 46 drive a set of rotating wheels 48 to rotate, rotating wheels 48 drive conveyor belt 49 to rotate, thus realizing the rotation of another set of rotating wheels 48. Both sets of rotating wheels 48 rotate simultaneously, and the other set of rotating wheels 48 drives rotating shaft 46 to rotate, so that both sets of rotating shafts 46 start to rotate.

[0042] Two sets of rotating shafts 46 drive two sets of driving wheels 410 to rotate, which in turn drive two sets of secondary conveyor belts 411 to rotate. These secondary conveyor belts 411 drive two sets of driven wheels 412 to rotate, which in turn drive two sets of feeding rollers 413 to rotate. The rotating shafts 46 rotate intermittently, thus causing the two sets of rotating wheels 48 and driving wheels 410 to rotate intermittently, which in turn causes the two sets of driven wheels 412 to rotate intermittently, and consequently, the two sets of feeding rollers 413 to rotate intermittently, thus intermittently moving the steel plate. When the steel plate to be stamped moves to the top of the worktable 39, firstly, the hydraulic cylinder 32 retracts, causing the connecting seat 33 to move towards the center position. Secondly... The connecting seat 33 drives a set of sliding seats 34 to move towards the center position. The set of sliding seats 34 drives a set of racks 311 to move towards the center position, thereby enabling the racks 311 to drive the first gear 310 to rotate. Furthermore, the first gear 310 drives another set of racks 311 to move, thereby enabling both sets of racks 311 to move towards the center position. The other set of racks 311 drives the other set of sliding seats 34 to move towards the center position. The two sets of sliding seats 34 slide along the outer walls of the two sets of sliding rods 36. The two sets of sliding seats 34 drive the two sets of clamping plates 35 to move towards the center position, thereby clamping the steel plate to be stamped. The stamping mechanism 1 is started to stamp the clamped steel plate.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
