Description

Technical Field

[0001] The utility model relates to the technical field of metal manufacturing equipment, in particular to a metal powder continuous extrusion molding device. Background Art

[0002] Traditional metal powder metallurgy is a process that uses various metal powders as raw materials to manufacture finished products and metal materials through pressing, sintering and necessary subsequent processing. In the 1930s, metal powder metallurgy successfully produced porous oil-containing bearings. With the use of cheap iron powder, powder metallurgy began to be widely used in industrial fields such as automobiles and textiles.

[0003] Under the existing technology, when a continuous extrusion molding device for metal powder is used for metal forging, a fixed amount of metal powder is first added into the mold through the feed port, and then the metal powder is continuously extruded by hydraulic equipment. After the metal is formed, the extrusion is stopped. At this time, the formed metal part needs to be separated from the mold. However, since the metal part is formed by continuous extrusion, it is time-consuming and labor-intensive to separate it, and other devices are required to assist in demolding. It cannot be directly demolded through the continuous extrusion molding device. For this reason, we propose a continuous extrusion molding device for metal powder. Utility Model Content

[0004] A technical problem to be solved by the present application is that the metal powder continuous forming device under the existing technology cannot directly demould the formed metal parts.

DETAILED DESCRIPTION

[0024] 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 embodiments 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.

[0025] Example 1:

[0026] See also Figure 1-4 The utility model provides a technical solution for a metal powder continuous extrusion molding device: a metal powder continuous extrusion molding device, including a combination mold 1 and a hydraulic press 2. The combination mold 1 and the hydraulic press 2 are both existing technologies and will not be described in detail here. It also includes: a mobile flipping mechanism 3 arranged on one side of the combination mold 1, which drives the combination mold 1 to be lifted and flipped through the mobile flipping mechanism 3.

[0027] The combined mold 1 includes a base plate 11, and a mold frame 12 is provided at the upper end of the base plate 11; one side of the mold frame 12 is rotatably connected to a connecting shaft 13 through a rotating shaft, where the rotating shaft is a damping rotating shaft, which will cause damping between the mold frame 12 and the connecting shaft 13, and the mold frame 12 can stop and stabilize at any time when it rotates. A threaded ring 14 is fixedly provided on one side of the connecting shaft 13, and the threaded ring 14 is provided to enable it to be sleeved on the threaded shaft 34, and to drive the threaded ring 14 to move thereon when the threaded shaft 34 rotates. A rotating column 15 is fixedly provided on the other side of the mold frame 12, and the rotating column 15 is provided to more conveniently rotate the mold frame 12; the mobile flipping mechanism 3 includes a lifting bin 31, and a protective plate 32 is fixedly provided on one side of the lifting bin 31, and the protective plate 32 is L-shaped. A threaded shaft 34 is provided inside the lifting bin 31, and a bevel gear 35 is provided at one end of the threaded shaft 34, and a bevel gear 2 36 is provided on one side of the bevel gear 1 35, and a motor 37 is provided at the upper end of the protective plate 32; a connecting column 38 is fixedly provided at one end of the threaded shaft 34 close to the bevel gear 1 35, and the connecting column 38 passes through the bevel gear 1 35 and is connected to the threaded shaft 34, and the connecting column 38 is rotatably connected to the protective plate 32; a movable groove 33 is provided on the side of the protective plate 32, and the movable groove 33 is adapted to the connecting shaft 13, and the threaded ring 14 is sleeved on the outer wall of the threaded shaft 34 and adapted thereto; the bevel gear 1 35 is fixedly provided at one end of the threaded shaft 34, and the output shaft of the motor 37 is connected to the center of the bevel gear 2 36, and the bevel gear 1 35 is meshed with the bevel gear 2 36.

[0028] The motor 37 is fixedly arranged at the upper end of the protective plate 32. The model of the motor 37 is KYDAS96300-1E. This is the existing technology and will not be described in detail here. A control button 39 is provided at the upper end of the lifting bin 31. The control button 39 is electrically connected to the motor 37, and the operation of the motor 37 is controlled by the control button 39. By setting up a mobile flipping mechanism 3, the motor 37 is used to drive the threaded shaft 34 to rotate through the engagement of the bevel gear 1 35 and the bevel gear 2 36, thereby driving the mold frame 12 to lift through the threaded ring 14. When it is lifted to the highest point, the mold frame 12 is rotated and flipped through the rotating column 15 to reverse the metal part, and the metal part is demolded by the cooperation of the hydraulic press 2.

[0029] First, a certain amount of metal powder is added into the mold frame 12, and the hydraulic press 2 is started to repeatedly squeeze the mold frame 12 up and down. After the metal powder is extruded and formed, the hydraulic press 2 is moved up, and then the output shaft of the motor 37 is controlled by the control button 39 to start rotating. The rotation of the output shaft of the motor 37 will drive the bevel gear 2 36 to rotate, and the rotation of the bevel gear 2 36 will drive the bevel gear 1 35 meshing with it to rotate. The rotation of the bevel gear 1 35 will drive the threaded shaft 34 to rotate. The rotation of the threaded shaft 34 will cause the threaded ring 14 threadedly connected thereto to start moving on the threaded shaft 34, and at the same time, the mold frame 12 is driven upward through the connecting shaft 13 and the rotating shaft. When the mold frame 12 moves to the highest point, the rotating column 15 at the other end is used to manually drive the mold frame 12 to flip. Since the rotating shaft is a damping rotating shaft, the mold frame 12 stops rotating after it is completely flipped, and the mold frame 12 will not deflect at will. At this time, the hydraulic press 2 is turned on to start squeezing the metal parts in the mold frame 12, so that they are separated from the mold frame 12.

[0030] Example 2:

[0031] See also Figure 4-5 The utility model provides a technical solution for a metal powder continuous extrusion molding device: a metal powder continuous extrusion molding device, comprising a limiting column 16 fixedly provided at the upper end of a base plate 11, a limiting hole 17 in a rectangular shape is opened on the mold frame 12, and the limiting column 16 is adapted to the limiting hole 17; by setting the limiting column 16 and the limiting hole 17, the mold frame 12 and the base plate 11 are fixed by utilizing the limiting hole 17 and the limiting column 16, when the mold frame 12 is inverted and lowered to a certain position away from the base plate 11, the limiting column 16 and the limiting hole 17 are aligned and inserted therein, and at this time the metal part is separated from the mold frame 12 by downward squeezing by the hydraulic press 2.

[0032] Through the limiting holes 17 thereon, the position of the mold frame 12 is finely adjusted so that the limiting holes 17 are aligned with the limiting posts 16 on the base plate 11. This can prevent the mold frame 12 from failing to rotate completely during flipping, thereby causing the mold frame 12 to fail to be level. This will cause the hydraulic press 2 to be in the wrong position when pressing down, thereby damaging the mold frame 12 and the metal parts therein.
