Description

Technical Field

[0001] The present invention relates to the technical field of alloy valve body production, and particularly relates to a rapid prototyping forging device and process for a superalloy valve body. Background Art

[0002] Havard upset forging is a metal forming process. During the upset forging process, the metal material is usually placed in a mold, and then an external force is applied to deform it, so as to obtain a workpiece with the required shape. Compared with the traditional forging process, Havard upset forging has higher production efficiency and better material utilization rate.

[0003] However, at present, Havard upset forging can only forge the outer contour of the valve body, and its inner cavity cannot be formed in one step. A series of subsequent means such as turning processing are still required. For this reason, we propose a rapid prototyping forging device and process for a superalloy valve body. Summary of the Invention

On the left and right sides of the forging table, first cylinders are symmetrically arranged. On the opposite sides of the two first cylinders, molds are provided to control the closing and opening of the two molds. The structures of the two molds are the same, and a T-shaped three-way groove is opened therein. In the vertical section of the three-way groove, a valve body groove adapted to the shape of the valve body is provided. The valve body groove includes a spherical groove in the middle. Both the upper and lower ends of the spherical groove are connected to flange grooves through straight-through grooves;

[0008] A second cylinder is provided on the forging table.

On the side of the first pressing plate facing the inside of the three-way groove, a first pressing column and a second pressing column are successively provided. A gap is left between the first pressing column and the second pressing column and the inner wall of the horizontal section of the three-way groove, so that a groove for cooperating with the valve stem is formed when forging the valve body;

[0013] Preferably, a receiving groove for receiving the cutting mechanism is formed on the outer wall of the third pressing column. The receiving groove communicates with the cavity. Sliding grooves are formed on both sides of the receiving groove. Sliders are slidably connected in both sliding grooves. Support springs connecting the tops of the two sliders to the top of the sliding groove are provided on both sides. The cutting mechanism is rotatably connected with the sliders on both sides, so that the cutting mechanism can move upwards obliquely relative to each other.

[0014] Preferably, the cutting mechanism includes a cutting arm rotatably connected with the slider. On the side of the cutting arm facing the cavity, it is rotatably connected with the swing plate, and on the other side, a multi-sided cutter is provided.

[0015] Preferably, the multi-sided cutter has a plurality of cutting edges.

[0016] Preferably, a limiting block protruding outwards is provided on the side of the cutting arm facing the cavity. The widths of the limiting block and the cutting arm are the same as the width in the receiving groove, so that when the multi-sided cutter rotates, the receiving groove limits the cutting arm and the limiting block.

[0017] Preferably, motors are symmetrically provided on the upper and lower sides of the forging table. The output ends of the motors on the upper and lower sides are both provided with third cylinders, so that the motors can drive the third cylinders to rotate.

[0022] S4. Start the second cylinder and the third cylinder, so that the first extrusion column and the second extrusion columns on the upper and lower sides make reciprocating movements in the mold. Through multiple extrusions and releases, an internal space is formed in the forged valve body in the mold.

Detailed implementation manners

[0046] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0047] Referring to the attached Figures 1-11 , a rapid prototyping forging device for a superalloy valve body, including a forging table 1, first cylinders 2 are symmetrically arranged on both left and right sides of the forging table 1, molds 3 are arranged on the opposite sides of the two first cylinders 2 to control the mold closing and mold opening of the two molds 3, the structures of the two molds 3 are the same, and their mold cavities can be mutually combined into the required valve body shape, and a T-shaped three-way groove 31 is opened therein. A valve body groove adapted to the valve body shape is arranged in the vertical section of the three-way groove 31. The valve body groove includes a spherical groove 32 in the middle. Both upper and lower ends of the spherical groove 32 are connected with flange grooves 34 through straight-through grooves 33. After heating the alloy material, it is put into the mold 3 so that the alloy material can form the required valve body shape in the mold 3;

[0048] A second cylinder 4 is arranged on the forging table 1, and the output end of the second cylinder 4 is connected with a first extrusion column 5 for cooperating with the horizontal section of the three-way groove 31. Third cylinders 7 are arranged on both upper and lower sides of the forging table 1, and the output ends of the third cylinders 7 are connected with second extrusion columns 8 to cooperate with the vertical section of the three-way groove 31.

[0049] During use, after putting the superalloy material into the mold 3, start the second cylinder 4 and the third cylinder 7, and control the first extrusion column 5 and the second extrusion column 8 to reciprocate in the three-way groove 31 of the mold 3. Through cooperation with the mold 3, the outer shape of the heated alloy material is forged into the valve body shape, and the inside of the valve body is formed with a water flow channel and a channel for installing a valve stem after being extruded by the first extrusion column 5 and the second extrusion column 8. Subsequently, only a small amount of processing on the grooves inside the valve body is required to complete the forging and forming of the valve body. Compared with the traditional Haff upset forging method, the space inside the valve body can be forged, and only a small amount of subsequent processing is required to complete the processing of the valve body, greatly shortening the processing time.

[0050] The first extrusion column 5 includes a first pressing disk 51 adapted to the inner wall of the horizontal section of the three-way groove 31. A first pressing column 52 and a second pressing column 53 are sequentially arranged on the side of the first pressing disk 51 facing the inside of the three-way groove 31. A gap is left between the first pressing column 52 and the second pressing column 53 and the inner wall of the horizontal section of the three-way groove 31 so that a groove for cooperating with the valve stem is formed when forging the valve body. When the first pressing disk 51 reciprocates on the inner wall of the horizontal end of the three-way groove 31, the first pressing disk 51 always maintains the sealing of the end of the horizontal end of the three-way groove 31. The first pressing column 52 and the second pressing column 53 cooperate to forge the formed valve body so that a groove for installing the valve stem is formed inside it;

[0051] The second extrusion post 8 includes a second pressing disc 81 adapted to the inner wall of the vertical end of the three-way groove 31. On the side of the second pressing disc 81 facing the inside of the three-way groove 31, a third pressing post 82 and a third pressing disc 83 are successively provided. A gap is left between the third pressing post 82 and the third pressing disc 83 and the inner wall of the straight-through groove 33 so that a water flow channel is formed inside the forging valve body. When the second extrusion post 8 reciprocates inside the vertical end of the three-way groove 31, the second pressing disc 81 always maintains the seal of the vertical end of the three-way groove 31, and the third pressing disc 83 reciprocates to forge the formed valve body so that a channel for water flow is formed inside it.

[0052] The diameter of the third pressing post 82 is smaller than that of the third pressing disc 83. A cutting tool mechanism 9 is provided on the third pressing post 82 so that when the third pressing post 82 drives the cutting tool mechanism 9 to rotate, a spherical inner cavity is formed in the middle of the vertical section of the forging valve body. After the valve body is initially forged and formed, the first pressing post 52 is controlled to move away from the spherical groove 32, and then the cutting tool mechanism 9 is controlled to rotate. At this time, the cutting tool mechanism 9 cuts the middle position inside the valve body and forms a spherical inner cavity.

[0053] A cavity 821 is opened inside the third pressing post 82. A fourth air cylinder 822 is provided inside the cavity 821. The output end of the fourth air cylinder 822 is connected with a U-shaped push plate 823. A sleeve plate 824 is hinged inside the U-shaped push plate 823. A swing plate 825 is slidably connected inside the sleeve plate 824. One end of the swing plate 825 is hinged inside the third pressing post 82, and the other end is hinged with the cutting tool mechanism 9 to push the cutting tool mechanism 9 to move outwards. The fourth air cylinder 822 is started, and the sleeve plate 824 is pushed upwards through the U-shaped push plate 823, further causing the swing plate 825 to swing upwards. At this time, the cutting tool mechanism 9 moves away from the third pressing post 82 and presents an inclined state, and then the cutting tool mechanism 9 is controlled to rotate for spherical cutting.

[0054] A receiving groove 826 for receiving the cutting tool mechanism 9 is opened on the outer wall of the third pressing post 82. The receiving groove 826 is communicated with the cavity 821. Sliding grooves 827 are opened on both sides of the receiving groove 826. Sliding blocks 828 are slidably connected inside both sliding grooves 827. Support springs 829 connecting the tops of the two sliding blocks 828 to the tops of the sliding grooves 827 are provided on the tops of both sliding blocks 828. The cutting tool mechanism 9 is rotatably connected with the sliding blocks 828 on both sides so that the cutting tool mechanism 9 can move relatively upwards and obliquely. When the cutting tool mechanism 9 is pushed upwards by the swing plate 825, the sliding blocks 828 will move upwards when the cutting tool mechanism 9 moves outwards, further enabling the cutting tool mechanisms 9 on both sides to approach each other, reducing the gap between the cutting tool mechanisms 9 on both sides when performing spherical cutting on the valve body, so as to facilitate the formation of a more precise spherical inner cavity during cutting.

[0055] The cutting tool mechanism 9 includes a cutting tool arm 91 rotatably connected to the slider 828. One side of the cutting tool arm 91 facing the cavity 821 is rotatably connected to the swing plate 825, and a multi-sided cutting tool 92 is provided on the other side. The swing plate 825 swings and pushes the cutting tool arm 91 to move, so that the multi-sided cutting tool 92 moves out of the cavity 821, facilitating the multi-sided cutting tool 92 to cut the inner wall of the valve body.

[0056] The multi-sided cutting tool 92 has multiple cutting edges, facilitating the cutting of the inner wall of the valve body when it rotates.

[0057] A limiting block 93 protruding outward is provided on one side of the cutting tool arm 91 facing the cavity 821. The width of the limiting block 93 and the cutting tool arm 91 is the same as the width inside the receiving groove 826. When the multi-sided cutting tool 92 rotates, the receiving groove 826 limits the cutting tool arm 91 and the limiting block 93. After the cutting tool arm 91 deflects outward, both the cutting tool arm 91 and the limiting block 93 are within the receiving groove 826. When the multi-sided cutting tool 92 rotates along the axis of the second pressing column 8, the receiving groove 826 limits the cutting tool arm 91 and the limiting block 93 to prevent the multi-sided cutting tool 92 from shaking too much during the rotation cutting process, which may affect the cutting quality.

[0058] Motors 6 are symmetrically provided on the upper and lower sides of the forging table 1. The output ends of the motors 6 on the upper and lower sides are both provided with third cylinders 7, enabling the motors 6 to drive the third cylinders 7 to rotate. When the motors 6 on the upper and lower sides are started, the motors 6 drive the third cylinders 7 to rotate, further causing the second pressing column 8 to rotate. At this time, the cutting tool mechanism 9 can rotate following the second pressing column 8 to complete the cutting of the spherical space inside the valve body.

[0059] A rapid prototyping forging process for a superalloy valve body is as follows:

[0060] S1. Put the alloy material into a high-temperature melting furnace for high-temperature melting. First, preheat the temperature of the material to 750 - 800 °C and maintain the temperature for 0.5 - 1 h to ensure uniform temperature distribution inside the material and reduce the risk of deformation during forging.

[0061] S2. Continue to heat the preheated material to the forging temperature, which is 1100 - 1300 °C, and maintain the temperature for 20 - 40 min to make the material reach the best plasticity and fluidity, facilitating subsequent forging and forming.

[0062] S3. Use a manipulator to take out the material and place it into the mold 3. Control the two-sided mold 3 to close. During the closing process, ensure the accuracy and stability of the two-sided mold 3 to prevent the forged valve body from deforming.

[0063] S4. Start the second cylinder 4 and the third cylinder 7 so that the first extrusion column 5 and the second extrusion columns 8 on the upper and lower sides reciprocate in the mold 3. Through multiple extrusions and releases, an internal space is formed in the valve body forged in the mold 3.

[0064] S5. Control the cutter mechanism 9 to rotate about the axis of the second extrusion column 8 so that a spherical inner cavity is formed in the valve body.

[0065] S6. Control the first extrusion column 5 and the second extrusion column 8 to move away from the forged valve body, and then control the two molds 3 to be demolded to remove the forged valve body.

[0066] S7. After forging, slowly cool the valve body to room temperature, and then perform solution treatment, quenching and tempering heat treatment processes.

[0067] Solution treatment: Heat the valve body to a certain temperature of 1000 - 1200 °C and keep the temperature for 15 - 30 min to promote the uniform distribution of elements inside the material.

[0068] Quenching: Quickly cool the valve body after solution treatment to room temperature to increase the hardness and strength of the material.

[0069] Tempering: Heat the quenched valve body to 550 - 700 °C and keep the temperature for 10 - 30 min to eliminate the residual stress generated during quenching and improve the toughness and stability of the material.

[0070] S8. Perform trimming on the valve body after the treatment in step S7 to remove the excess edge material, and then polish and grind the inside and outside of the valve body to improve the aesthetics of the valve body forming to complete the processing of the valve body.

Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non - exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
