Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a shell stamping forming die. Background Art

[0002] Stamping dies are special process equipment used to process materials into parts during cold stamping. They are called cold stamping dies. When a rectangular electrical shell is stamped, the blank first contacts the inner wall of the port of the lower die, and then contacts the bottom wall of the lower die along the inner wall. This causes the port of the lower die to be in contact with the blank for a long time, resulting in severe wear. The inner wall of the lower die near the bottom wall is less worn, resulting in uneven wear of the lower die, which affects the quality of the shell stamping and also affects the service life of the die. Utility Model Content

[0003] The utility model aims to solve the shortcomings of the prior art that uneven wear of the lower die affects the service life of the die, and proposes a shell stamping die.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A shell stamping forming die is designed, comprising a base, a workbench is fixedly connected to the base, a through slot is opened in the middle of the workbench, a support plate is abutted in the through slot, a support mechanism is arranged at the lower end of the support plate, a fixing ear is arranged on the workbench, a rotating shaft is rotatably connected to the fixing ear through a bearing, a frame is fixedly connected to the rotating shaft, the frame abuts against the support plate, a support frame is fixedly connected to the workbench, and an upper die is fixedly connected to the support frame through a stamping mechanism.

[0006] Preferably, the support mechanism includes two hinged rods, the two hinged rods are hinged to the support plate, the lower ends of the two hinged rods are hinged with sliders, the two sliders can be slidably set on the slide rail, the slide rail is fixedly connected to the base, and the two sliders are positioned by a positioning mechanism.

[0007] Preferably, the positioning mechanism comprises a connecting ear, the connecting ear is fixedly connected to the sliding block, a fixing column is provided through the connecting ear, a connecting sleeve is fixedly connected to the base, and the fixing column can be inserted into the connecting sleeve.

[0008] Preferably, the two fixing columns are fixedly connected via a connecting plate.

[0009] Preferably, a limiting sleeve is fixedly connected to the workbench, a fixing ear is placed in the limiting sleeve, a bolt is threadedly penetrated and connected on the limiting sleeve, and the bolt abuts against the fixing ear.

[0010] Preferably, the stamping mechanism is a hydraulic cylinder.

[0011] Preferably, reinforcing ribs are provided on the support frame.

[0012] The utility model proposes a shell stamping forming die, which has the beneficial effect of: by moving the support plate downward, the frame can be rotated around the rotating shaft, so that the upper and lower ends of the frame are reversed, so as to ensure that the inner wall of the lower die wears uniformly during stamping, thereby ensuring the quality of the shell stamping and forming, and also helping to extend the service life of the die. At the same time, when the support plate is separated from the support for the frame, the upper die can continue to move downward to push the formed shell out of the frame for demolding.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Example 1

[0020] Reference Figure 1-4A shell stamping forming mold includes a base 6, a workbench 5 is fixedly connected to the base 6, a through groove is opened in the middle of the workbench 5, a support plate 7 is abutted in the through groove, a support mechanism is arranged at the lower end of the support plate 7, a fixing ear 16 is arranged on the workbench 5, a rotating shaft 8 is rotatably connected to the fixing ear 16 through a bearing, a frame 4 is fixedly connected to the rotating shaft 8, the frame 4 is abutted against the support plate 7, a support frame 3 is fixedly connected to the workbench 5, and a reinforcing rib is arranged on the support frame 3.

[0021] The support frame 3 is fixedly connected with an upper mold 1 through a stamping mechanism 2. The stamping mechanism 2 is a hydraulic cylinder. The frame 4 is supported by a support plate 7 to form a lower mold, so that the support plate 7 moves downward, and the frame 4 can rotate around the rotating shaft 8, thereby inverting the upper and lower ends of the frame 4 to ensure that the inner wall of the lower mold wears uniformly during stamping, thereby ensuring the quality of the shell stamping and forming, and is also beneficial to extending the service life of the mold. At the same time, when the support plate 7 is separated from the support for the frame 4, the upper mold 1 can continue to move downward to push the formed shell out of the frame 4 for demoulding.

[0022] The supporting mechanism includes two articulated rods 10, which are hinged to the supporting plate 7. The lower ends of the two articulated rods 10 are hinged with sliders 11. Both sliders 11 can be slidably set on the slide rail 9. The slide rail 9 is fixedly connected to the base 6. The two sliders 11 are positioned by the positioning mechanism and support the supporting plate 7 through the articulated rods 10.

[0023] The positioning mechanism includes a connecting ear 13, which is fixedly connected to the slider 11. A fixing column 15 is provided through the connecting ear 13. A connecting sleeve 14 is fixedly connected to the base 6. The fixing column 15 can be inserted into the connecting sleeve 14. Pulling the fixing column 15 out of the connecting sleeve 14 will release the limit on the slider 11, so as to adjust the inclination angle of the hinge rod 10, thereby causing the support plate 7 to descend and separate from the frame 4.

[0024] The two fixing columns 15 are fixedly connected by a connecting plate 12 , so that the connecting plate 12 can be taken to simultaneously separate the two fixing columns 15 from the connecting sleeve 14 .

[0025] When in use, the hydraulic cylinder extends, causing the upper mold 1 to enter the frame 4 for stamping, taking the connecting plate 12, disengaging the two fixing columns 15 from the connecting sleeve 14 at the same time, releasing the limit on the slider 11, and adjusting the inclination angle of the hinge rod 10, so that the support plate 7 is lowered and disengaged from the frame 4, allowing the frame 4 to rotate around the rotating shaft 8, thereby inverting the upper and lower ends of the frame 4 to ensure that the inner wall of the frame 4 wears uniformly.

[0026] Example 2

[0027] In Example 1, since the frame 4 will wear out, it needs to be replaced when the wear is too large. Figure 1-4 As another preferred embodiment of the utility model, on the basis of embodiment 1, a limiting sleeve 17 is fixedly connected to the workbench 5, a fixing ear 16 is placed in the limiting sleeve 17, a bolt is threadedly connected to the limiting sleeve 17, and the bolt abuts against the fixing ear 16. The fixing ear 16 is fixed by the bolt. When the frame 4 needs to be replaced, the bolt is loosened and the frame 4 is removed so as to replace the frame 4.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
