Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a forging machine. Background Art

[0002] Rare metal targets play an indispensable role in integrated circuit chip manufacturing. They can be used in thin film deposition and barrier layer manufacturing, boasting a wide range of applications. Due to the unique nature of the industry, the rare metal ingots used to manufacture these targets are subject to stringent requirements, requiring their microscopic internal structure and appearance to meet standards. As raw materials, rare metal ingots may have internal defects such as porosity and shrinkage, requiring forging to enhance their structural functionality.

[0003] In the existing technology, when forging rare metal ingots, cracks are easily generated on the material surface due to collision and extrusion, so that the standards for manufacturing rare metal targets cannot be met. Therefore, if a crack occurs at one end during the forging process, it needs to be turned immediately to prevent the crack from expanding. However, this also results in excessive turning consumables and reduces the product yield. Utility Model Content

[0029] like Figure 1-Figure 3As shown, this embodiment provides a forging machine, which includes a frame 1 and a forging assembly. The frame 1 is provided with a driving mechanism, and the forging assembly includes a first forging part 21 and a second forging part 22 provided in a corresponding manner. The driving mechanism is used to drive the first forging part 21 and the second forging part 22 to move toward or away from each other. The side surface of the first forging part 21 close to the second forging part 22 is a first forging surface, and the side surface of the second forging part 22 close to the first forging part 21 is a second forging surface 222. The first forging surface and / or the second forging surface 222 are provided with a receiving groove 221, which is used to accommodate a defective portion of the metal material. When making an ingot of rare metal material, the rare metal material is first placed between the first forging surface and the second forging surface 222, but not placed corresponding to the receiving groove 221. The forging machine performs forging. If no cracks are generated on the surface of the rare metal material during the forging process, the forging is successful, and the finished product can be directly used as a rare metal target material; if cracks are generated on the surface of the rare metal material during the forging process, the forging machine is shut down, and the position of the rare metal material is adjusted so that the location where the cracks appear corresponds to the position of the receiving groove 221. The forging machine is restarted, and the forging machine works to press the defective part of the rare metal material into the receiving groove 221 as a whole. At this time, a protrusion with the same shape as the receiving groove 221 is generated on the surface of the rare metal material. The defective part of the rare metal can be removed by simply cutting out the protrusion to restore the rare metal material to a flat state. That is, the forging machine can use the first forging surface and the second forging surface 222 to perform normal forging on the metal material. When cracks appear in the metal material, the metal material is moved to place the metal material in the corresponding receiving groove 221, and the cracked part is pressed into the receiving groove 221 and cut out by the center line. A single forging machine can realize two functions without the need for additional tooling, thereby reducing production costs.

[0030] Specifically, in this embodiment, the first forging 21 and the second forging 22 are arranged vertically with spacing therebetween. The first forging 21 is located above the second forging 22. The lower surface of the first forging 21 is the first forging surface, and the upper surface of the second forging 22 is the second forging surface 222. When processing rare metal materials, they can be supported simply by placing them on the second forging surface 222, eliminating the need for a separate support platform. Furthermore, the first forging 21 serves as the upper anvil, and the second forging 22 serves as the lower anvil.

[0031] Furthermore, in this embodiment, the driving mechanism is used to drive the first forging 21 to move up and down in the vertical direction, the second forging 22 is fixed relative to the frame 1, and the receiving groove 221 is located on the second forging surface 222. The rare metal material is placed on the second forging surface 222, and when the driving mechanism drives the first forging 21 to move up and down, it will not cause shaking due to the movement of the rare metal material; at the same time, the receiving groove 221 is located on the second forging surface 222, which is easy to correspond to the defective part of the rare metal material on the second forging surface 222. Furthermore, the second forging 22 is fixedly connected to the frame 1 by a connecting member. In some other embodiments, the second forging 22 can also be fixed to the floor, which is not limited in this embodiment.

[0032] Furthermore, in this embodiment, the receiving groove 221 is centrally located on the second forging surface 222. When the rare metal material is forged and its defective portion is pressed into the receiving groove 221, the rare metal material also corresponds to the middle portion of the first forging 21, which helps to apply uniform pressure to the first forging 21 and prevents the rare metal material from generating more cracks due to uneven force.

[0033] Furthermore, in this embodiment, a spacer 3 is provided on the lower surface of the second forging 22. The spacer 3 can elevate the height of the second forging 22, facilitating the press-fitting of the first forging 21 and the second forging 22. The spacer 3 can be a spacer strip provided on corresponding sides of the second forging 22, or a spacer plate, which is not limited in this embodiment.

[0034] Specifically, in this embodiment, the receiving groove 221 is a V-shaped groove. When the defective portion of the rare metal material is pressed into the V-shaped groove, the angle at the boundary between the pressed portion and the other portions is an acute angle, and the smaller the angle, the smaller the probability of cracks due to deformation at the boundary; in addition, the smaller the angle, the smaller the volume pressed into the V-shaped groove, and the less additional material is consumed during wire cutting. Furthermore, the angles between the two side walls of the V-shaped groove and the second forging surface 222 are the same, and the angles are both less than 45°. In some other embodiments, the receiving groove 221 may also be an arc-shaped groove, which is not limited in this embodiment.

[0035] Specifically, in this embodiment, the forging machine is also provided with a filling block, which can be filled into the receiving groove 221. When the filling block is filled into the receiving groove 221, the upper surface of the filling block is flush with the second forging surface 222, that is, the second forging surface 222 is a plane as a whole when the filling block is filled. At this time, the rare metal material can be directly placed on the upper surface of the filling block for normal forging; if the rare metal material produces cracks, the filling block can be taken out. The setting of the filling block allows the rare metal material to be placed in the middle position of the second forging surface 222 during normal forging, ensuring the uniformity of the force on the rare metal material; it can also make more full use of the area of ​​the second forging surface 222, so that the forging machine can forge rare metal materials of larger sizes. Furthermore, the filling block is made of the same material as the second forging part 22.

[0036] Furthermore, the wall of the receiving groove 221 is provided with a sliding groove, and the filling block is provided with a sliding protrusion, which is slidably mounted on the sliding groove. That is, the filling block can achieve a sliding connection with the receiving groove 221 through the cooperation of the sliding protrusion and the sliding groove. At the same time, the cooperation between the sliding protrusion and the sliding groove can prevent the filling block and the receiving groove 221 from sliding relative to each other in the circumferential direction, thereby preventing the upper surface of the filling block from not being flush with the second forging surface 222. In some other embodiments, the wall of the receiving groove 221 can also be provided with a protrusion, and the filling block can be provided with a sliding groove.

[0037] Specifically, in this embodiment, the notch of the receiving groove 221 is configured as a transition arc surface. When the rare metal material is forged, the surface of the rare metal material is also forged to form an arc surface with the same shape as the transition arc surface. At this time, the deformation near the rare metal material is relatively gentle, and it is less likely to generate new cracks due to excessive deformation.

[0038] Specifically, in this embodiment, at least two receiving slots 221 are provided, each having different volumes. When forging rare metal ingots of different sizes, different volume requirements are placed on the receiving slots 221. Providing multiple receiving slots 221 of varying volumes allows for selective use based on specific needs, avoiding excessive material consumption during wire cutting due to excessively large receiving slots 221, and preventing the inability to completely remove defective portions due to insufficiently small receiving slots 221.

[0039] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
