[0028] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof. Example 1

[0029] A sheet metal stamping equipment with replaceable molds, such as Figure 1-Figure 8As shown, it includes a base 1, a power mechanism 2, a rotating mechanism 3 and a stamping mechanism 4. The base 1 is provided with a power mechanism 2, and the right part of the base 1 is provided with a power mechanism 2. The power mechanism 2 includes a motor 21, a missing gear 22 and a large gear 23. The right part of the base 1 is equipped with a motor 21 by bolts, and the output shaft of the motor 21 is connected with the missing gear 22 by a coupling. A rotating shaft is rotatably installed on the base 1, and a large gear 23 is welded on the right end of the rotating shaft. The large gear 23 is meshed with the missing gear 22. The middle part of the base 1 is provided with a rotating mechanism 3, and the rotating mechanism 3 includes a rotating plate 31, a gear lever 32, a mold 33, a stamping plate 34, a threaded rod 35 and a fixed block 36. The rotating shaft is connected with a rotating plate 31, and four rotating pages are evenly distributed on the rotating plate 31. The rotating pages are all penetrated with a gear lever 32, and the rotating pages are all welded with a mold 33. The types of the four molds 33 are different, and the four molds 33 can be disassembled and replaced. The front sides of the four molds 33 are marked The names corresponding to the types of the molds 33 are annotated. Stamping plates 34 are slidably provided on the turning pages. The stamping plates 34 are all located below the gear lever 32. The stamping plates 34 are all located above the mold 33. The upper side of the stamping plates 34 is connected to a threaded rod 35. The left and right sides of the stamping plates 34 are connected to fixed blocks 36, and the fixed blocks 36 are L-shaped. A stamping mechanism 4 is provided on the base 1. The stamping mechanism 4 includes a cylinder 41, a guide rod 42, a connecting rod 43 and a first connecting plate 44. A cylinder 41 is installed on the upper end of the base 1, and the height of the movable part of the cylinder 41 when it rises is higher than the length of the four turning pages. The connecting parts at the lower part of the cylinder 41 can be threadedly fixed with the threaded rod 35. Guide rods 42 are symmetrically welded on the base 1. Connecting rods 43 are connected to the lower connecting parts of the cylinder 41. The left and right ends of the connecting rod 43 slide with the guide rod 42. The lower part of the guide rod 42 is rotatably provided with a first connecting plate 44, and the first connecting plate 44 is located at the bottom of the fixed block 36.

[0030] When the present invention is to be used, the first connecting plate 44 is first rotated 180 degrees, and the connecting piece at the lower part of the cylinder 41 is rotated to be threadedly fixed with the threaded rod 35. After the fixing is completed, the first connecting plate 44 is reset, the gear rod 32 is pulled out, and then the cylinder 41 is started. The cylinder 41 will move the stamping plate 34 upward, and the connecting rod 43 will slide on the guide rod 42. At this time, the sheet metal to be stamped is placed in the mold 33, and the cylinder 41 presses the stamping plate 34 downward again to complete the stamping. After the stamping is completed, the worker places the stamped sheet metal into the collection box 75, and then places a new sheet metal into the mold 33, and repeats this process. When the mold 33 needs to be replaced, the cylinder 41 is first closed, the connecting piece at the lower part of the cylinder 41 is rotated to release the fixation with the threaded rod 35, the first connecting plate 44 is rotated 180 degrees, and then the gear rod 32 is inserted back into the rotating page, and the cylinder 41 is started. After the cylinder 41 rises, the cylinder 41 is turned off, and then the motor 21 is started. The output shaft of the motor 21 will rotate the missing gear 22. When the gear teeth of the missing gear 22 are in contact and mesh with the large gear 23, the missing gear 22 will rotate with the large gear 23, thereby rotating the rotating plate 31 through the rotating shaft. When the rotating plate 31 rotates the mold 33 to be used to the bottom of the cylinder 41, the motor 21 is turned off. At this time, the missing gear 22 is meshed with the large gear 23, and the rotating plate 31 is fixed. Then the first connecting plate 44 is reset, thereby completing the replacement of the mold 33. The rotating plate 31 is driven by the motor 21 to rotate and replace the heavy-weight mold 33. The workers only need to perform simple disassembly work, which makes the replacement of the mold 33 simple and labor-saving. When a mold 33 other than the four molds 33 on the equipment needs to be used, the mold 33 can be removed from the equipment and replaced with a new mold 33. Example 2

[0031] On the basis of Example 1, Figure 1 , Figure 6 and Figure 7 As shown, an auxiliary fixing mechanism 5 is also included, wherein the auxiliary fixing mechanism 5 includes a fixing plate 51 and a pull rod 52. The fixing plate 51 is symmetrically slidably arranged in the base 1, and the pull rod 52 is welded to the bottom side of the fixing plate 51, and the pull rod 52 is slidably matched with the base 1.

[0032] like Figure 1 and Figure 7 As shown, an auxiliary moving mechanism 6 is also included, wherein the auxiliary moving mechanism 6 includes an L-shaped rod 61 and a second connecting plate 62, the L-shaped rod 61 is slidably provided on the guide rod 42, the lower end of the L-shaped rod 61 is rotatably connected to the second connecting plate 62 through a rotating shaft, the other end of the second connecting plate 62 is rotatably connected to the outer side of the fixed plate 51, and the first elastic member 45 is connected between the L-shaped rod 61 and the lower part of the connecting rod 43 through a spring seat.

[0033] like Figure 1 , Figure 2 and Figure 8 As shown, it also includes a mounting frame 71, a collection box 75, a clamping and fixing mechanism 7 and a slide rail 76. The front side of the base 1 is connected to the mounting frame 71, and the mounting frame 71 is provided with a collection box 75; wherein the clamping and fixing mechanism 7 includes a fixing rod 72, a clamping block 73 and a second elastic member 74, and the left and right parts of the mounting frame 71 are symmetrically penetrated with fixing rods 72, and the ends of the two fixing rods 72 close to each other are connected with clamping blocks 73 by bolts, and the collection box 75 is located between the two clamping blocks 73, and the second elastic member 74 is connected between the mounting frame 71 and the clamping block 73, and the initial state of the second elastic member 74 is compressed; the bottom side of the collection box 75 is symmetrically connected to two slide rails 76, and the collection box 75 is slidably matched with the mounting frame 71 through the slide rails 76.

[0034] Since the rotating plate 31 is mainly fixed by the meshing of the missing gear 22 and the large gear 23, when the cylinder 41 presses down with the stamping plate 34, the pressure is relatively large, and the fixed plate 51 will share a certain amount of pressure with the mold 33, thereby reducing the wear of the missing gear 22 and the large gear 23. When the mold 33 needs to be replaced, the pull rod 52 is pulled outward, and the pull rod 52 will drive the fixed plate 51 to move outward. In this way, the fixed plate 51 will not affect the rotation of the rotating plate 31.

[0035] When the cylinder 41 rises, the connecting rod 43 will also move upward, and the connecting rod 43 will move up with the L-shaped rod 61. The upward movement of the L-shaped rod 61 will cause the angle of the second connecting plate 62 to change, so that the fixing plate 51 can be pulled out of the base 1. The cylinder 41 can be raised and the fixing plate 51 can be pulled out of the base 1 at the same time, without the need for workers to pull it out manually.

[0036] Place the collection box 75 between the two clamping blocks 73, the clamping block 73 will compress the second elastic member 74, and the second elastic member 74 will also feedback force to the clamping block 73, thereby fixing the collection box 75. When the collection box 75 is full, the two clamping blocks 73 are squeezed to the left and right sides so that the collection box 75 can be taken out, and the slide rail 76 can make the collection box 75 easily taken out.

[0037] The above-mentioned embodiments only express the preferred implementation modes of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
