DETAILED DESCRIPTION

[0022] 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.

[0023] Example 1

[0024] Reference Figure 1-4 , a stamping die for convenient material blanking, comprising a fixed frame 1, a lower die 2 is fixedly connected to the fixed frame 1, a punching hole 4 is opened on the lower die 2, a hydraulic cylinder 5 is fixedly connected to the upper end of the fixed frame 1, an upper die 6 is fixedly connected to the telescopic end of the hydraulic cylinder 5, the upper die 6 cooperates with the lower die 2, a pushing mechanism 3 for convenient material blanking is connected to the lower die 2, a plurality of limiting plates 7 are fixedly connected to the upper end of the lower die 2, the limiting plates 7 and the lower die 2 are an integral structure, a plurality of connecting holes are opened on the upper die 6, and a plurality of limiting plates 7 pass through different connecting holes, a collecting box 8 is fixedly connected to the fixed frame 1, and the collecting box 8 is located below the punching hole 4;

[0025] The pushing mechanism 3 includes a connecting rod 32, and a first groove 31 is opened at the upper end of the lower mold 2. The connecting rods 32 are slidably inserted on both sides of the first groove 31, and one end of the connecting rod 32 is fixedly connected to a pushing plate 33, and the other end of each connecting rod 32 is fixedly connected to a fixing block 34, and each fixing block 34 is fixedly connected to a spring 35, and one end of each spring 35 is fixedly connected to the lower mold 2.

[0026] Working process: under the limit of the limit plate 7, the stamping part is placed against the inner wall of the lower mold 2, and the stamping part is placed on the push plate 33. After the hydraulic cylinder 5 is started, it drives the upper mold 6 to move downward for a set distance and then cooperate with the lower mold 2. The lower mold 2 presses the stamping part downward, and the stamping part presses the push plate 33. The push plate 33 drives the fixed block 34 to move downward through the connecting rod 32. After the fixed block 34 moves downward, it pulls the spring 35. The spring 35 generates elastic force after being compressed. The push plate 33 moves downward for a distance and then retracts into the first groove 31. At this time, the stamping part contacts the inner upper end of the lower mold 2, and the upper mold 6 punches the stamping part. The fragments produced by the punching fall from the punching hole 4, and the fallen fragments fall into the collection box 8 to collect the fragments.

[0027] After the stamping is completed, the hydraulic cylinder 5 drives the upper mold 6 to move upward and reset. After the upper mold 6 is separated from the stamping part, the fixing block 34 is driven to move upward and reset under the elastic force of the spring 35. The fixing block 34 pushes the push plate 33 upward through the connecting rod 32, and the push plate 33 pushes the stamping part upward, so that the push plate 33 moves upward and resets, and the stamping part is misaligned with the lower mold 2, which is convenient for removing the stamping part.

[0028] Example 2

[0029] When the lower die 2 and the upper die 6 cooperate in stamping, the stamping will generate noise, and the punch hole 4 is opened on the lower die 2, and the noise generated is released from the punch hole 4, resulting in a relatively high noise in the working environment. Figure 5-6 As another preferred embodiment of the utility model, on the basis of embodiment 1, the bottom end of each punching hole 4 is connected to a noise reduction mechanism 9, and the noise reduction mechanism 9 includes a fixed tube 91, which is fixedly connected to the bottom end of the punching hole 4. A second groove 92 is provided in the fixed tube 91, and a fixed net 93 is fixedly connected to the second groove 92. A sound-absorbing filler layer 94 is provided in the second groove 92, and the sound-absorbing filler layer 94 is a sound-absorbing cotton layer. The generated noise enters the fixed tube 91 through the punching hole 4, and the sound-absorbing filler layer 94 absorbs the noise entering the fixed tube 91, thereby reducing the noise volume. After the fragments fall from the punching hole 4, the fallen fragments pass through the fixed tube 91, and the fixed net 93 protects the sound-absorbing filler layer 94 to prevent the fragments from colliding with the sound-absorbing filler layer 94.

[0030] 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.
