[0040] Please see Figure 1-9 This invention provides a technical solution: a multifunctional continuous forming device for strip-shaped blanks, comprising:

[0041] The upper mold mechanism 1 includes an upper mold plate 11, a backing plate 12, a stripper plate 13, a trimming punch 14, an upper forming punch 15, and a suction member 16. The backing plate 12 is fixedly installed on the upper mold plate 11, and the stripper plate 13 is elastically connected to the backing plate 12. The trimming punch 14 is fixedly installed on the upper mold plate 11 and passes through the stripper plate 13. The trimming punch 14 includes two punch units arranged symmetrically in opposite directions. The upper mold plate 11 is provided with trimming punches 14 arranged sequentially along a straight line. The upper forming punch 15 and the suction member 16 are provided. A lower viewing vision 4 is provided between the upper forming punch 15 and the suction member 16. The lower viewing vision 4 is mounted on the first drive arm 41. A material discharge groove 5 is also provided on one side of the upper mold mechanism 1. The material discharge groove 5 is connected to the second drive arm. One end of the material discharge groove 5 extends to the bottom of the suction member 16. The suction member 16 is used to pick up the product 31. The material discharge groove 5 moves in and out between the upper mold mechanism 1 and the lower mold mechanism 2 through the second drive arm. The lower viewing vision 4 moves in and out in the same way.

[0042] The lower mold mechanism 2 includes a lower template 21, a floating plate 22, and a lower forming punch 23. The lower template 21 is provided with a guide groove 211, and the strip blank 3 is placed in the guide groove 211. The bottom surface of the guide groove 211 is provided with a first dropping hole 212 corresponding to the punch unit. The floating plate 22 is elastically connected to the lower template 21. The lower forming punch 23 is positioned below the upper forming punch 15 and passes through the floating plate 22.

[0043] Two parallel drilling assemblies 6 are provided on one side of the lower mold plate 21. Each drilling assembly 6 includes a drill bit 61, which is positioned above the guide groove 211. A second discharge hole 213, corresponding to the position of the drill bit 61, is provided on the bottom surface of the guide groove 211. When the upper mold mechanism 1 and the lower mold mechanism 2 are closed, the drilling assembly 6 is located in the gap between the upper mold plate 11 and the lower mold plate 21. The drilling assembly 6 drives the drill bit 61 to descend and drill holes in the bottom edge of the un-drilled product 31. Waste material falls into the second discharge hole 213, further enriching the function of the continuous forming device and improving production efficiency.

[0044] The upper template 11 is also equipped with a positioning element 17, and two drilling components 6 are symmetrically arranged on both sides of the positioning element 17. The positioning element 17 is used to press and position the product 31 that needs to be drilled. When the mold is closed, the bottom of the positioning element 17 contacts the product 31, which facilitates the two drilling components 6 to drill accurately.

[0045] A pressure block 171 is provided at the bottom of the positioning component 17. The pressure block 171 is elastically connected to the positioning component 17 to prevent damage to the product 31 when the pressure block 171 presses down on the product 31.

[0046] The upper forming punch 15 is provided with a stripping pin 151 inside. The stripping pin 151 passes through the upper forming punch 15 and is elastically connected to the upper template 11, which facilitates the separation of the product 31 from the upper forming punch 15.

[0047] A through hole is provided on the bottom surface of the feeding trough 5, and a glass plate 51 is placed inside the through hole. A top-viewing vision device 52 is provided below the feeding trough 5, and the position of the top-viewing vision device 52 corresponds to that of the glass plate 51. The top-viewing vision device 52 is designed to inspect the lower side of the product 31, further improving the accuracy of appearance inspection and increasing production efficiency.

[0048] The product forming process in the continuous forming device is as follows:

[0049] 1. The strip blank 3 is placed in the guide groove 211 of the lower template 21 and conveyed forward in a straight line along the guide groove 211;

[0050] 2. The strip blank 3 is conveyed to the underside of the cutting punch 14. The upper die mechanism 1 and the lower die mechanism 2 close the mold for the first time. One end of the strip blank 3 is cut by the two punch units, and the waste falls into the first blanking hole 212. Then the upper die mechanism 1 and the lower die mechanism 2 separate the mold for the first time, and the strip blank 3 is conveyed forward a fixed distance.

[0051] 3. The upper mold mechanism 1 and the lower mold mechanism 2 close the mold for the second time. The other end of the strip blank 3 is cut by two punch units, and the waste falls into the first blanking hole 212. Then the upper mold mechanism 1 and the lower mold mechanism 2 separate the mold for the second time. The strip blank 3 is conveyed forward a fixed distance. At this time, one end of the strip blank 3 becomes a circular blank. The circular blank also has a connection point with the strip blank 3 itself.

[0052] 4. The circular blank at one end of the strip blank 3 is conveyed to the lower part of the upper forming punch 15. The upper mold mechanism 1 and the lower mold mechanism 2 close the mold for the third time. The upper forming punch 15 squeezes the floating plate 22, and the circular blank is cut and separated from the strip blank 3. At the same time, the upper forming punch 15 cooperates with the lower forming punch 23 to extrude and form the circular blank into an un-drilled product 31. Then the upper mold mechanism 1 and the lower mold mechanism 2 separate the mold for the third time. The strip blank 3 is conveyed forward a fixed distance, and the un-drilled product 31 is squeezed by the strip blank 3 to the drilling assembly 6.

[0053] 5. Driven by the first drive arm 41, the downward vision 4 extends between the upper mold mechanism 1 and the lower mold mechanism 2 (above the un-drilled product 31) to achieve appearance inspection of the un-drilled product 31.

[0054] 6. Then, the upper mold mechanism 1 and the lower mold mechanism 2 close the mold for the fourth time. The lower vision 4 moves out before the mold closes. The upper mold mechanism 1 and the lower mold mechanism 2 separate the mold for the fourth time. The strip blank 3 is conveyed forward a fixed distance. The product 31 is squeezed by the next formed product 31 to the bottom of the suction part 16.

[0055] 7. The upper mold mechanism 1 and the lower mold mechanism 2 close the mold for the fifth time, and the suction component 16 picks up the product 31. The upper mold mechanism 1 and the lower mold mechanism 2 separate the mold for the fifth time, and the suction component 16 drives the product 31 upward. The next product 31 is squeezed to the bottom of the suction component 16. Under the action of the second drive arm, the unloading groove 5 moves to the bottom of the suction component 16. The suction component 16 releases its suction force, and the product 31 falls into the unloading groove 5. According to the appearance inspection result of the product 31, the second drive arm moves the unloading groove 5 to different unloading robots (not shown in the figure) for unloading.

[0056] 8. Repeat the above process to achieve continuous stamping.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
