Description

Technical Field

[0001] The utility model relates to the technical field of nickel-based alloy ring forgings, and more specifically, it relates to a press for producing nickel-based alloy ring forgings. Background Art

[0002] Nickel-based high-temperature alloys have high long-lasting strength and good comprehensive performance in the range of 500℃-800℃. The alloy is widely used in the manufacture of important load-bearing parts such as turbine disks, compressor disks, guide vanes, and load-bearing rings of aircraft engines. Ring forgings made of nickel-based alloys need to be forged using a press.

[0003] At present, when the existing press processes nickel-based alloy ring forgings, it is necessary to place the nickel-based alloy ring forging rod in a mold and forge it into a nickel-based alloy ring forging of a desired shape through the press. During the forging process of the nickel-based alloy ring forging rod on the press, a small amount of residue will remain inside the press mold. However, after the mold has been used many times, the residue accumulated inside the mold gradually increases and adheres to the mold. If it is not handled for a long time, it is easy to cause the mold to be unusable and affect the forging shape of the nickel-based alloy ring forging. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide a press for producing nickel-based alloy ring forgings.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a press for producing nickel-based alloy ring forgings, comprising a main body component and an extrusion component installed inside the main body component.

[0006] The main body component includes a frame and a base installed on the bottom wall of the frame. The extrusion component is arranged above the base. Flipping components are installed on both sides of the frame. Two groups of flipping components are hinged to the upper mold.

[0007] The extrusion assembly includes an upper mold and a lower mold arranged inside a frame, a hinge is installed between one side of the lower mold and the same side of the base, an extrusion cylinder is installed vertically downward at the top of the frame, and the piston rod of the extrusion cylinder is connected to the top of the upper mold.

[0008] The utility model is further configured as follows: the two groups of flipping assemblies each include a flipping cylinder hinged on both sides of the frame, a first connecting rod is provided on both sides of the frame, the two first connecting rods are provided corresponding to the two flipping cylinders, the piston rod of the flipping cylinder is hinged to the middle of the bottom surface of the corresponding first connecting rod, the end of the first connecting rod is hinged to the second connecting rod, connecting plates are installed on both sides of the lower mold, the two connecting plates are provided corresponding to the two second connecting rods, and the connecting plates are hinged to the ends of the corresponding second connecting rods away from the first connecting rods.

[0009] The utility model is further configured as follows: two bearing seats are installed above the front surface of the frame, rotating shafts are passed through the two bearing seats, and one end of the two first connecting rods away from the corresponding second connecting rods is connected to the outer wall of the rotating shaft.

[0010] The utility model is further configured as follows: a tension spring is connected between the top of the connecting plate and the side wall corresponding to the second connecting rod.

[0011] The utility model is further configured as follows: the side walls of the two second connecting rods are each provided with a through slot, and the two connecting plates are connected to a limiting column near one end of the corresponding second connecting rod, and the limiting column is passed through the inside of the corresponding through slot.

[0012] By adopting the above technical solution, when the flip cylinder pushes the first connecting rod to swing, the first connecting rod drives the second connecting rod to move up and down, and the connecting plate moves up and down synchronously. The connecting plate pulls the lower mold to swing, so that the lower mold can switch between a horizontal state and an open and tilted downward state. When the lower mold is in the open and tilted downward state, the ring forgings and residues inside the lower mold are discharged together to avoid the accumulation of residues in the lower mold affecting the subsequent processing of the ring forgings.

[0013] The utility model is further configured as follows: a rubber pad for buffering is bonded to the bottom of the lower mold, and the size of the rubber pad is the same as the bottom surface of the lower mold.

[0014] By adopting the above technical solution, since the limit column can slide inside the corresponding through groove, the hinge point between the connecting plate and the second connecting rod is not fixed, but is set within the internal length range of the through groove 38. When the lower mold is in a horizontal state, the lower mold and the connecting plate are affected by gravity to drive the limit column to slide to the innermost part of the corresponding through groove, and in this state, the support is pulled by the tension spring between the connecting plate and the second connecting rod. When the lower mold recovers to a horizontal state from an inclined state, not only is the bottom of the lower mold buffered by the rubber pad, but also when the lower mold contacts the base, if the second connecting rod continues to move downward, the connecting plate squeezes the tension spring, and the elastic contraction of the tension spring buffers the connecting plate and the lower mold.

[0015] In summary, the present application includes at least one of the following beneficial technical effects:

[0016] (1) By setting a flip assembly, when the flip cylinder pushes the first connecting rod to swing, the first connecting rod drives the second connecting rod to move up and down, and the connecting plate moves up and down synchronously. The connecting plate pulls the lower mold to swing, so that the lower mold can switch between a horizontal state and an open and tilted downward state. When the lower mold is in the open and tilted downward state, the ring forgings and residues inside the lower mold are discharged together, so as to avoid the accumulation of residues in the lower mold affecting the subsequent processing of the ring forgings.

[0017] (2) When the lower mold is in a horizontal state and the connecting plate is affected by gravity, the limit column slides to the innermost part of the corresponding through groove, and in this state, the support is pulled by the tension spring between the connecting plate and the second connecting rod. When the lower mold is restored to a horizontal state from an inclined state, not only is the bottom of the lower mold buffered by the rubber pad, but also when the lower mold contacts the base, if the second connecting rod continues to move downward, the connecting plate squeezes the tension spring, and the elastic contraction of the tension spring buffers the connecting plate and the lower mold.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0025] See also Figure 1-4 , the utility model provides the following technical solutions:

[0026] For example, see Figure 1 A press for producing nickel-based alloy ring forgings comprises a main assembly 1 and an extrusion assembly 2 installed inside the main assembly 1. The rod to be forged is placed inside the extrusion assembly 2. The extrusion assembly 2 is used to process the rod into the shape of a nickel-based alloy ring forging. The specific structures of the main assembly 1 and the extrusion assembly 2 are as follows:

[0027] See also Figure 1 The main component 1 includes a frame 11 and a base 12 installed on the bottom wall of the frame 11. The extrusion component 2 is arranged above the base 12. The extrusion component 2 is divided into two parts. The frame 11 and the base 12 support the two parts of the extrusion component 2 respectively.

[0028] See also Figure 1-Figure 3 The extrusion assembly 2 includes an upper die 21 and a lower die 22 which are arranged inside the frame 11. A hinge 23 is installed between one side of the lower die 22 and the same side of the base 12. The lower die 22 is hinged to the base 12 by the hinge 23, so that the lower die 22 can be flipped on the top of the base 12 through the hinge 23, and the lower die 22 is used to place the raw material bar of the ring forging to be forged.

[0029] See also Figure 1-Figure 3 An extrusion cylinder 24 is installed vertically downward on the top of the frame 11. The piston rod of the extrusion cylinder 24 is connected to the top of the upper mold 21. The extrusion cylinder 24 is used to push the upper mold 21 to move up and down. When the lower mold 22 is in a horizontal state and the raw material bar is placed, the extrusion cylinder 24 pushes the upper mold 21 to move downward to pressurize the raw material bar inside the lower mold 22, thereby making the raw material into a desired shape.

[0030] During the forging process of the nickel-based alloy ring forging bar on the press, a small amount of residue will remain inside the press die. However, after the die has been used many times, the residue accumulated inside the die gradually increases and adheres to the die. If it is not handled for a long time, it is easy to cause the die to be unusable and affect the forging shape of the nickel-based alloy ring forging. For this reason, a flip assembly 3 is installed on both sides of the frame 11. Both sets of flip assemblies 3 are hinged to the upper die 21. When the ring forging is completed, the upper die 21 is driven away from the lower die 22 by the extrusion cylinder 24, and then the lower die 22 is driven by the flip assembly 3 to flip at the top of the base 12. The top opening of the lower die 22 is tilted downward, causing the ring forging to be discharged from the lower die 22, and the residue remaining in the lower die 22 is discharged together, so as to avoid the accumulation of residue in the lower die 22 affecting the forging process of the next raw material. The specific structure of the flip assembly 3 is as follows:

[0031] See also Figure 1-Figure 3 In this embodiment, the two groups of flipping assemblies 3 include a flipping cylinder 31 hinged on both sides of the frame 11, and a first connecting rod 32 is provided on both sides of the frame 11. The two first connecting rods 32 are arranged corresponding to the two flipping cylinders 31. The piston rod of the flipping cylinder 31 is hinged at the middle part of the bottom surface of the corresponding first connecting rod 32. The flipping cylinder 31 is used to push the first connecting rod 32 to move up and down. Two bearing seats 34 are installed above the front surface of the frame 11. A rotating shaft 35 is passed through the two bearing seats 34. The ends of the two first connecting rods 32 away from the corresponding second connecting rods 33 are connected to the outer wall of the rotating shaft 35. Through this arrangement, one end of the first connecting rod 32 is fixed by the bearing seat 34 and the rotating shaft 35. When the flipping cylinder 31 pushes the first connecting rod 32 to move up and down, the first connecting rod 32 drives the rotating shaft 35 to rotate inside the bearing seat 34, causing the first connecting rod 32 to swing up and down along the axis direction of the bearing seat 34.

[0032] See also Figure 1-Figure 3 The end of the first connecting rod 32 is hinged with the second connecting rod 33, and connecting plates 37 are installed on both sides of the lower mold 22. The two connecting plates 37 are arranged corresponding to the two second connecting rods 33. The connecting plates 37 are hinged with the ends of the corresponding second connecting rods 33 away from the first connecting rod 32. The end of the first connecting rod 32 away from the rotating shaft 35 drives the corresponding second connecting rod 33 to move up and down, and the bottom end of the second connecting rod 33 pulls the connecting plate 37 to move up and down. Since the connecting plate 37 is connected to the lower mold 22, and the lower mold 22 is hinged on the base 12 through the hinge 23, when the connecting plate 37 follows the second connecting rod 33 to move up, it will tilt, and the connecting plate 37 and the lower mold 22 will rotate along the hinge axis of the hinge 23, causing the lower mold 22 to flip from a horizontal state to an open downward state, thereby facilitating the discharge of ring forgings and residues. When the second connecting rod 33 moves downward, the connecting plate 37 and the lower mold 22 are restored to a horizontal state.

[0033] See also Figure 1-Figure 3 In this embodiment, a rubber pad 391 for buffering is bonded to the bottom of the lower mold 22. The size of the rubber pad 391 is the same as the bottom surface of the lower mold 22. When the lower mold 22 is restored from the open tilted downward state to the horizontal state, in order to avoid the lower mold 22 and the base 12 from colliding, the rubber pad 391 is used for buffering between the two.

[0034] See also Figure 1-Figure 3 The locking cam 38 is actuated by the hinge 23 and the locking cam 39 is engaged with the locking cam 39 so that the locking cam 39 can be engaged with the locking cam 39.

[0035] See also Figure 4 In addition, since the limiting column 39 can slide inside the corresponding through slot 38, the hinge point between the connecting plate 37 and the second connecting rod 33 is not fixed, but is arranged within the internal length range of the through slot 38. A tension spring 36 is connected between the top of the connecting plate 37 and the side wall of the corresponding second connecting rod 33. When the lower mold 22 is in a horizontal state, the lower mold 22 and the connecting plate 37 are affected by gravity to drive the limiting column 39 to slide to the innermost part of the corresponding through slot 38, and in this state, the tension spring 36 between the connecting plate 37 and the second connecting rod 33 pulls and supports. When the lower mold 22 restores to a horizontal state from an inclined state, not only is the bottom of the lower mold 22 buffered by the rubber pad 391, but also when the lower mold 22 contacts the base 12, if the second connecting rod 33 continues to move downward, the connecting plate 37 squeezes the tension spring 36, and the elastic contraction of the tension spring 36 buffers the connecting plate 37 and the lower mold 22.

[0036] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
