Description

Technical Field

[0001] The utility model relates to the technical field of punch accessories, in particular to a quick-assembly punch die. Background Art

[0002] The production and preparation process of cemented carbide products involves multiple steps such as powder making, pressing, and sintering. Among them, pressing refers to filling the alloy powder into the die and using external force to compact the alloy powder into a shape for subsequent shaping and sintering. At present, the production process of powder pressing and molding mostly adopts a two-way pressing and molding method, that is, during the pressing process, both ends of the powder in the die move relative to the die wall, which can obtain a more uniform and dense powder compact compared with the traditional unidirectional pressing.

[0003] For example, the patent with publication number CN106141175A discloses a single-mold multi-porous forming die for powder metallurgy rod blank products, which involves a single-mold multi-porous die that can achieve bidirectional pressing. Before pressing, the matching die components need to be assembled to the corresponding positions of the die respectively. In the existing die punch assembly as mentioned above, screws are often used for alignment and fixation, that is, the punch is first supported by hand and placed in the corresponding position, and then tightened with multiple screws arranged diagonally. However, in the above operation, the different tightening degrees of different screws will cause the assembly position of the punch to shift or tilt, etc., which ultimately causes the problem of low assembly accuracy. The assembly accuracy of the die assembly directly determines the quality of the product, such as the dimensional accuracy, and the repeated alignment and tightening process requires a lot of time and manpower.

[0004] Based on the above situation, there is an urgent need for a punch die that can be assembled more accurately and efficiently. Utility Model Content

[0008] Preferably, a limiting groove is recessed on the surface of the fastening base close to the connecting gland, and the limiting groove can accommodate the connecting gland.

[0009] Preferably, the groove portion of the limiting groove has the same size as the end portion of the connecting cover, so that the limiting groove and the connecting cover can be mortise-engaged.

[0010] Preferably, a plurality of fastening holes are recessed on the outer wall surface of the connecting gland.

[0011] Preferably, the surface of the fastening base is provided with an adjusting bolt, and the side wall of the adjusting bolt is penetrated with an adjusting tooth. The fixing part includes a push rod, and the side wall surface of the push rod close to the adjusting tooth is provided with a rack, and the rack can engage with the adjusting tooth. The push rod is slidably connected to the surface of the fastening base through the adjusting bolt and the adjusting tooth, and one end of the push rod can abut against the connecting cover.
