Description

Technical Field

[0002] A metal target is a target material bombarded by high-speed energetic particles, including metals, alloys, oxides, etc. Among them, the metal target needs to be processed by an upsetting process during production.

[0003] Upsetting is a forging process that reduces the height of a blank and increases its cross-sectional area. If only a local cross-sectional area of the blank is increased, it is called local upsetting. The functions of upsetting include: obtaining a forging with a larger cross-sectional area and a smaller height from a blank with a smaller cross-sectional area, increasing the cross-sectional area of the blank and flattening the end face before punching, increasing the forging ratio during the next drawing process, improving the transverse mechanical properties of the forging and reducing anisotropy, repeatedly upsetting and drawing to break the carbides in alloy tool steel and make their distribution uniform, etc.

[0004] In the upsetting process, the operator needs to adjust the target blank to control the upsetting process of the target blank. This process is carried out manually, which requires high experience of the operator. Moreover, for some workpieces with a large weight, the operation difficulty is greater, and the processing process is time-consuming and laborious. Summary of the Utility Model

[0032] Please refer to Figures 1-3 , the present utility model is a tooling die for upsetting process, including a die sleeve 10 and a gripping rod 20. Among them, the die sleeve 10 is used to limit the target blank during the upsetting process, and the shape and size of the target blank are ensured by the die sleeve 10. The gripping rod 20 is fixedly arranged on the side wall of the die sleeve 10 and is used for the operator to grab to adjust the position of the die and the target blank therein. Among them, the dimension unit marked in the accompanying drawings is mm, and it is an example of the dimension parameters based on a certain type of target blank, rather than a complete limitation on the dimensions of the present device.

[0033] Please refer to Figures 1-2, in one embodiment of the present utility model, a cavity for accommodating a target blank is provided inside the die sleeve 10. The size of the cavity corresponds to the processing size of the target blank. During use, the target blank heated to a high temperature is placed into the mold, and then forging is carried out to ensure the shape and size of the target blank by using the mold. The inner wall of the die sleeve 10 is inclined, that is, the size of one end of the cavity is larger than that of the other end, so that the inner wall of the die sleeve 10 has a certain inclination angle, which facilitates demolding of the target blank after processing and ensures the stable progress of the upsetting process.

[0034] Please refer to Figures 1-3 , in one embodiment of the present utility model, one end of the grasping rod 20 is fixedly connected to the side wall of the die sleeve 10. The number of the grasping rods 20 can be set to be multiple, and the multiple grasping rods 20 are arranged evenly. By providing multiple grasping rods 20, multiple people can cooperate to move the die sleeve 10. For example, when the number of the grasping rods 20 is two, the two grasping rods 20 can be oppositely arranged on both sides of the die sleeve 10, and the die sleeve 10 is moved by the cooperation of two people.

[0035] Please refer to Figures 1-3 , in one embodiment of the present utility model, the connection mode between the grasping rod 20 and the die sleeve 10 can be threaded connection, welding, clamping or other connection modes. In this embodiment, as a preferred solution: a connection groove 11 is provided on the side surface of the die sleeve 10, internal threads are provided on the inner wall of the connection groove 11, a connection head 21 is fixedly provided at one end of the grasping rod 20, and external threads are provided on the connection head 21. The die sleeve 10 and the grasping rod 20 are fixedly connected by means of threaded connection. Further, in order to improve the connection stability between the two, the connection position between the grasping rod 20 and the die sleeve 10 is welded and fixed, so as to further improve the connection strength between the die sleeve 10 and the grasping rod 20 on the basis of threaded connection. The outer diameter size of the connection head 21 is smaller than the outer diameter size of the grasping rod 20, and a plurality of reinforcing blocks 12 are fixedly provided on the side wall of the die sleeve 10. The plurality of reinforcing blocks 12 are arranged at intervals around the connection groove 11, and the diameter size of the circle formed by enclosing the plurality of reinforcing blocks 12 matches the outer diameter size of the grasping rod 20. By providing the reinforcing blocks 12, on the one hand, they can act as welding points during the welding process, and on the other hand, they can provide radial support along the grasping rod 20, thereby greatly improving the connection strength between the grasping rod 20 and the die sleeve 10.

[0036] Please refer to Figures 1-3, in one embodiment of the present utility model, a holding portion may be provided at one end of the grasping rod 20 away from the die sleeve 10. The outer wall of the holding portion is provided with an anti-slip structure, and the anti-slip structure may be an anti-slip groove, an anti-slip protrusion or an anti-slip pattern, etc. By providing the holding portion, it is more convenient for the operator to grasp and operate, improving the convenience of use. The grasping rod 20 may be a hollow structure, thereby effectively reducing the weight of the grasping rod 20. The opening of the inner cavity of the grasping rod 20 may be sealed by welding a end cap to ensure the strength of the distal end (the end away from the die sleeve 10) of the grasping rod 20, and the outer diameter of the end cap matches the inner diameter of the inner cavity of the grasping rod 20.

[0037] The above has described in detail one embodiment of the present utility model, but the content described is only the preferred embodiment of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model.
