Description

Technical Field

[0001] The utility model relates to the technical field of dry powder forming presses, in particular to a connection device for dry powder forming presses. Background Art

[0002] Powder metallurgy is divided into two categories according to the molding medium: wet powder and dry powder molding. It is similar to the ceramic production process and both belong to powder sintering technology. Before high-temperature sintering, dry powder metallurgy products must first be pressed and molded by a dry powder molding press, and then the powder feeding device pushes the pressed and molded workpiece out of the die surface. The workpiece pushed out of the die surface will fall into the receiving box and cannot be directly transferred to the work surface. The workpiece will be piled up in the receiving box, resulting in defects or cracks in the appearance of the workpiece, increasing the defective rate of the product. Utility Model Content

[0003] The purpose of the utility model is to design a connection device for a dry powder forming press, so that it can solve the problems mentioned in the background technology.

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

[0005] A connection device for a dry powder forming press comprises a first support plate, a second support plate and a slideway, a support column is arranged between the first support plate and the second support plate, a fixing plate is arranged on both sides of one end of the slideway, a connecting hole matching with the support column is arranged at the bottom of the fixing plate, a fixing nut is arranged on the side of the fixing plate away from the slideway, a bolt is connected to the inner thread of the fixing nut, the tail end of the bolt contacts the support column, one end of the slideway close to the fixing plate is connected to the die ejection surface of the press, and the other end is placed on the work table.

[0006] Furthermore, it also includes a material receiving funnel, the first support plate and the second support plate are fixed on the top of the material receiving funnel, the slideway is provided with a plurality of sieve holes aligned with the material receiving funnel, and the bottom of the material receiving funnel is connected to a material pipe.

[0007] Furthermore, a recovery box is provided below the discharge port of the material pipe.

[0008] Furthermore, the receiving funnel is provided with supporting feet.

[0009] Furthermore, two ends of the support column are slidably connected to the first support plate and the second support plate respectively.

[0010] Furthermore, the first support plate and the second support plate are respectively provided with a first sliding hole and a second sliding hole, the two ends of the support column respectively pass through the first sliding hole and the second sliding hole, the end of the support column close to the first sliding hole is provided with an external thread, a limiting nut is threadedly connected to the external thread, and the end of the support column close to the second sliding hole is provided with a limit block.

[0011] The beneficial effects of the utility model are:

[0012] The slideway allows the workpiece pushed out from the die surface to slide into the slideway. The workpieces pushed out from the back can push the workpieces in front to slide onto the work surface along the slideway, thus avoiding the workpieces from being piled up in the receiving box, which would cause defects or cracks on the appearance of the workpieces, and greatly reducing the defective rate of the products.

[0013] When the height of the ejection surface changes, the bolt can be turned to quickly adjust the height of the slideway, so that the workpiece can slide neatly and without damage to the work surface through the slideway, reducing the defective rate of products;

[0014] When the height of the work surface changes, the slide can be rotated on the support column through the connecting hole of the slide, so that the slide can be rotated and the inclination angle of the slide can be changed, so that the slide can be placed on the work surface, and the workpiece can slide neatly and intactly through the slide to the work surface, reducing the product defect rate.
