Description

Technical Field

[0001] This utility model relates to the field of N06625 sphere forging technology, specifically to a mold for forging N06625 spheres. Background Technology

[0002] N06625 alloy is a nickel-based alloy with good corrosion resistance and high strength. It is widely used in aerospace, petrochemical and other fields. As one of the common processing shapes of this alloy, the sphere plays an important role in many key components.

[0003] Currently, when forging N06625 alloy spheres, workers need to use pliers to place the heated cylindrical N06625 alloy under a press for repeated extrusion molding. During the repeated extrusion process, in order to ensure that the cylindrical N06625 alloy can be extruded into a rough spherical blank that meets the quality standards, workers need to use pliers to repeatedly turn the workpiece so that the cylindrical N06625 alloy is extruded into a rough spherical blank. The manual turning process not only limits the forging efficiency of N06625 alloy spheres, but also poses safety hazards. Therefore, we propose a die for forging N06625 spheres. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0021] See attached document Figure 1-5 A die for forging N06625 spheres includes a press 1, a worktable 2 on the press 1, a lower die 3 on the worktable 2, and an upper die 4 on the press 1 corresponding to the lower die 3. Both the lower die 3 and the upper die 4 have arc-shaped grooves on their corresponding surfaces. A hydraulic cylinder is located on the top of the upper die 4 to control its reciprocating lifting motion. The specific control method is prior art and is not shown or described in detail in this application. The heated cylindrical workpiece is placed on the lower die 3, and then the upper die 4 is controlled to perform reciprocating lifting motion. During the process, the arc grooves on the upper mold 4 and the lower mold 3 can apply uniform pressure to the workpiece to be processed, causing it to gradually deform under the extrusion action. The worktable 2 is equipped with a flipping mechanism. During the repeated extrusion process of the workpiece to be processed, the flipping mechanism works and intermittently flips the workpiece to be processed, causing it to gradually flip to one side. Finally, during the reverse compound mold process, the workpiece to be processed is gradually extruded into a spherical rough blank structure. There is no need for workers to manually flip the workpiece to be processed, which reduces labor intensity, improves work efficiency, and enhances operational safety.

[0022] During the reverse compound molding process, the upper mold 4 and the lower mold 3 do not come into contact when they are closed, and there is a gap between them for the flipping mechanism to flip.

[0023] In this embodiment, the flipping mechanism includes a pair of clamping arms 51 disposed on the lower mold 3. One end of one clamping arm 51 is connected to the output end of the flipping motor 54. When the workpiece to be processed is placed on the lower mold 3, the two clamping arms 51 will be disposed on both sides of the workpiece to be processed, controlling the flipping motor 54 to rotate intermittently. At this time, under the action of the two clamping arms 51, the workpiece to be processed can also be flipped intermittently, thereby ensuring that the columnar workpiece can be squeezed into a spherical rough workpiece during the reverse compound mold process.

[0024] In this embodiment, the two clamping arms 51 are rotatably connected by a hinge shaft, and a tension spring 57 is connected between the two clamping arms 51 to provide pre-tightening force for the two clamping arms 51. When the cylindrical workpiece to be processed is placed on the lower mold 3, the two clamping arms 51 provide pre-tightening force under the action of the tension spring 57 to clamp the workpiece to be processed, so as to prevent it from tilting and affecting the deformation when the mold is closed. One end of one of the clamping arms 51 is provided with an extension arm 52. A flipping block 53 is sleeved on the outer wall of the extension arm 52. The flipping block 53 is connected to the output end of the flipping motor 54. When the flipping motor 54 is started, its output end will drive the flipping block 53 to rotate, which will further cause the extension arms 52 on both sides to deflect synchronously, thereby pushing the bottom of the workpiece to be processed, so that the workpiece to be processed will be flipped at a certain angle. When the workpiece is processed, the clamping arms 51 on both sides will be located on the lower side of the spherical blank workpiece. The flipping motor 54 is controlled to flip. At this time, under the pull of the tension spring 57, the clamping arms 51 on both sides can push the spherical blank workpiece to flip out of the clamping arms 51. A slide 6 is provided on one side of the lower mold 3. The slide 6 is set towards the workpiece flipping direction. The flipped spherical blank workpiece will be drawn along the slide 6, which saves manual material feeding operation, reduces labor intensity, and improves work efficiency.

[0025] Both the flipping block 53 and the extension arm 52 are arc-shaped structures. When the cylindrical workpiece is placed between the two clamping arms 51, the two clamping arms 51 will rotate around the hinge axis and move away from each other. At this time, the extension arm 52 can slide in the flipping block 53. The extension arm 52 will not be drawn out of the flipping block 53 to ensure that the flipping block 53 can drive the extension arm 52 to flip.

[0026] The axis of the output shaft of the flipping motor 54 is coaxial with the outermost tangent of the clamping arm 51 connected to the extension arm 52, so as to reduce the flipping distance of the clamping arm 51 connected to the extension arm 52 during the flipping process and avoid it hitting the lower mold 3 and affecting the material feeding.

[0027] In this embodiment, the bottom of the hinge shaft of the two clamping arms 51 is provided with a vertical plate 55, and the top of the worktable 2 is provided with a pair of limiting plates 56. A gap is left between the pair of limiting plates 56 for the vertical plate 55 to be inserted and slid. The vertical plate 55, together with the limiting plates 56 on both sides, can limit the direction of the clamping arm 51 during the deflection process, ensure the stability of its deflection, reduce the shaking and deviation during the movement, and improve the reliability of the flipping mechanism.

[0028] In this embodiment, in order to better adapt to workpieces of different sizes, the ends of the two clamping arms 51 that are away from the flipping motor 54 extend out of the lower mold 3, and the ends of the two arms that extend out of the lower mold 3 gradually narrow inward, so as to provide a more stable clamping force for the workpieces to be processed and prevent the workpieces from slipping during flipping and unloading. Example

[0029] This second embodiment has a structure that is basically the same as that of the first embodiment, the difference being: (Refer to Appendix) Figure 6 The flipping mechanisms are arranged in pairs on both sides of the lower mold 3. The clamping arms 51 on both sides extend to the middle position of the top of the lower mold 3. The flipping mechanisms on both sides work synchronously, which can better ensure the stability of the workpiece flipping.
