Description

Technical Field

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

[0002] Powder metallurgy is a technology that uses metal powder or a mixture of metal powder and non-metallic powder to manufacture metal materials, composite materials and various types of products through processes such as forming and sintering.

[0003] When metal powder is stamped, it needs to be added to the mold cavity through a feeding mechanism, and then the stamping machine drives the upper mold to stamp. After the stamping is completed, the formed metal parts are sent away. When the metal parts are sent away, the metal dust accumulated on the top of the lower mold is also pushed away and slowly accumulates together, which easily causes dust pollution. Utility Model Content

[0004] The purpose of the utility model is to provide a powder metallurgy stamping die to solve the problem of easy contamination of metal powders mentioned in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a powder metallurgy stamping die, comprising a lower die, a die cavity is provided in the middle of the top of the lower die, a top die is inserted into the die cavity, a placement cavity is provided on the top of the lower die, a frame and a dust collection module are provided on one side from top to bottom in the placement cavity, and a plurality of parallel rollers are rotatably connected in the frame.

[0006] Preferably, the distance between two adjacent rollers is 0.5-1 mm, and the rollers are flush with the top surface of the lower mold.

[0007] Preferably, a stopper is provided between the frame and the dust collection module, the stopper is plugged into the inner side of the placement cavity, and is elastically connected via a spring.

[0008] Preferably, the dust collection module includes a bottom plate, and a felt layer is fixedly connected to the top of the bottom plate.

[0009] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0010] The utility model provides a powder metallurgy stamping die, which absorbs dust dropped from the roller body through the felt layer in the dust collection module, thereby reducing pollution caused by accumulated dust. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figures 1-3 A powder metallurgy stamping die comprises a lower die 1, a die cavity 2 is provided through the middle of the top of the lower die 1, a top die 3 is inserted into the die cavity 2, the upper die is installed on the stamping machine and is pressed into the die cavity 2 by the stamping machine, a placement cavity 4 is provided on the top of the lower die 1, a frame 5 and a dust collection module 8 are provided on one side from top to bottom in the placement cavity 4, a plurality of parallel rollers 6 are rotatably connected in the frame 5, metal dust falls from between the rollers 6, and the felt layer 82 absorbs the metal dust falling between the rollers 6 to prevent the metal powder from floating into the air.

[0017] The distance between two adjacent rollers 6 is 0.5-1 mm, and the rollers 6 are flush with the top surface of the lower mold 1. The formed metal blocks are sent away from the rollers 6, and metal dust falls from between the rollers 6 and is not easy to float out.

[0018] A stopper 7 is provided between the frame 5 and the dust collecting module 8. The stopper 7 is inserted into the inner side of the placement cavity 4 and is elastically connected via a spring. The stopper 7 can support the frame 5 and can be pressed in to place the dust collecting module 8 into the placement cavity 4.

[0019] The dust collection module 8 includes a bottom plate 81 , and a felt layer 82 is fixedly connected to the top of the bottom plate 81 . The felt layer 82 absorbs the metal dust that falls between the rollers 6 to prevent the metal powder from floating into the air.

[0020] Working principle: The utility model is a powder metallurgy stamping die. When in use, the feeding mechanism feeds metal powder into the die cavity 2. The upper die is installed on the punching machine and is pressed into the die cavity 2 by the punching machine to stamp the metal powder into shape. After forming, the lower die 1 moves downward, and the formed metal part is pushed by the pushing mechanism through the top of the placement cavity 4. The metal dust falls from between the rollers 6, and the felt layer 82 absorbs the metal dust falling between the rollers 6 to prevent the metal powder from floating into the air.
