DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] Refer to the attached Figure 1-11 A high-temperature alloy valve body rapid prototyping forging device comprises a forging table 1, wherein first cylinders 2 are symmetrically arranged on the left and right sides of the forging table 1, and molds 3 are arranged on the opposite sides of the two first cylinders 2 to control the closing and parting of the two molds 3. The two molds 3 have the same structure, and their mold cavities can be assembled into a desired valve body shape. A T-shaped three-way groove 31 is provided therein, and a valve body groove adapted to the valve body shape is provided in the vertical section of the three-way groove 31. The valve body groove includes a middle spherical groove 32, and the upper and lower ends of the spherical groove 32 are connected to flange grooves 34 through straight grooves 33. After the alloy material is heated, it is put into the mold 3, so that the alloy material can form the desired valve body shape in the mold 3;

[0048] A second cylinder 4 is provided on the forging table 1, and the output end of the second cylinder 4 is connected to a first extrusion column 5 for cooperating with the lateral section of the tee groove 31. A third cylinder 7 is provided on the upper and lower sides of the forging table 1, and the output end of the third cylinder 7 is connected to a second extrusion column 8 for cooperating with the vertical section of the tee groove 31.

[0049] When in use, after placing the high-temperature alloy 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 shape of the heated alloy material is forged into a valve body shape, and the interior of the valve body is extruded by the first extrusion column 5 and the second extrusion column 8 to form a water flow channel and a channel for installing the valve stem. Subsequently, only a small amount of processing is required for the groove in the valve body to complete the forging of the valve body. Compared with the traditional Haver upsetting forging method, space inside the valve body can be forged, and only a small amount of processing is required subsequently to complete the processing of the valve body, which greatly shortens the processing time.

[0050] The first extrusion column 5 includes a first pressure plate 51 adapted to the inner wall of the transverse section of the three-way groove 31, and the first pressure plate 51 is provided with a first pressure column 52 and a second pressure column 53 in sequence on one side facing the inside of the three-way groove 31. A gap is left between the first pressure column 52 and the second pressure column 53 and the inner wall of the transverse section of the three-way groove 31, so that the forged valve body is formed with a groove matching the valve stem. When the first extrusion column 5 reciprocates on the inner wall of the transverse end in the three-way groove 31, the first pressure plate 51 always keeps the seal on the transverse end of the three-way groove 31. The first pressure column 52 and the second pressure column 53 cooperate to forge the formed valve body, so that a groove for installing the valve stem is formed inside the valve body.

[0051] The second extrusion column 8 includes a second pressure plate 81 adapted to the inner wall of the vertical end of the three-way groove 31, and the second pressure plate 81 is provided with a third pressure column 82 and a third pressure plate 83 in sequence on the side facing the three-way groove 31. A gap is left between the third pressure column 82 and the third pressure plate 83 and the inner wall of the straight groove 33 so that a water flow channel is formed in the forged valve body. When the second extrusion column 8 reciprocates inside the vertical end of the three-way groove 31, the second pressure plate 81 always keeps the vertical end of the three-way groove 31 sealed, and the third pressure plate 83 reciprocates to forge the formed valve body, so that a channel for flowing water is formed inside it.

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

[0053] A cavity 821 is provided in the third pressure column 82, and a fourth cylinder 822 is provided in the cavity 821. A U-shaped push plate 823 is connected to the output end of the fourth cylinder 822. A sleeve plate 824 is hinged in the U-shaped push plate 823. A swing plate 825 is slidably connected in the sleeve plate 824. One end of the swing plate 825 is hinged in the third pressure column 82, and the other end is hinged to the cutter mechanism 9 to push the cutter mechanism 9 to move outward. The fourth cylinder 822 is started and pushes the sleeve plate 824 upward through the U-shaped push plate 823, further causing the swing plate 825 to swing upward. At this time, the cutter mechanism 9 moves away from the third pressure column 82 and is in an inclined state. Then the cutter mechanism 9 is controlled to rotate to perform spherical cutting.

[0054] The outer wall of the third pressure column 82 is provided with a receiving groove 826 for accommodating the cutting mechanism 9, and the receiving groove 826 is connected to the cavity 821. Slide grooves 827 are provided on both sides of the receiving groove 826. Slide blocks 828 are slidably connected in the two slide grooves 827. The tops of the slide blocks 828 on both sides are provided with support springs 829 connected to the tops of the slide grooves 827. The cutting mechanism 9 is rotatably connected to the slide blocks 828 on both sides so that the cutting mechanism 9 can move upwardly and tiltedly. When the swing plate 825 pushes the cutting mechanism 9 upward, the slide block 828 is forced to move upward during the outward movement of the cutting mechanism 9, thereby further allowing the cutting mechanisms 9 on both sides to approach each other, reducing the gap between the cutting mechanisms 9 on both sides when performing spherical cutting on the valve body, so that the spherical inner cavity formed by cutting is more precise.

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

[0056] The polygonal cutter 92 has a plurality of blade surfaces so as to cut the inner wall of the valve body when the polygonal cutter 92 rotates.

[0057] A limit block 93 protruding outward is provided on the side of the cutter arm 91 facing the cavity 821. The width of the limit block 93 and the cutter arm 91 is the same as the width in the accommodating groove 826, so that when the multilateral cutter 92 rotates, the accommodating groove 826 limits the cutter arm 91 and the limit block 93. After the cutter arm 91 deflects outward, the cutter arm 91 and the limit block 93 are both in the accommodating groove 826. When the multilateral cutter 92 rotates along the axis of the second extrusion column 8, the accommodating groove 826 limits the cutter arm 91 and the limit block 93 to prevent the multilateral cutter 92 from shaking too much during the rotation and cutting process, affecting 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 provided with third cylinders 7, so that the motor 6 can drive the third cylinder 7 to rotate. The motors 6 on the upper and lower sides are started. At this time, the motor 6 drives the third cylinder 7 to rotate, and further rotates the second extrusion column 8. At this time, the cutting mechanism 9 can rotate with the second extrusion column 8 to complete the cutting of the spherical space in the valve body.

[0059] A high-temperature alloy valve body rapid forming forging process, the process steps are as follows:

[0060] S1. Place the alloy material in a high-temperature melting furnace for high-temperature melting. Preheat the material to 750-800°C and maintain the temperature for 0.5-1h 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℃, and maintain the temperature for 20-40min, so that the material can achieve the best plasticity and fluidity, which is convenient for subsequent forging and shaping;

[0062] S3, taking out the material by a manipulator and putting it into the mold 3, controlling the molds 3 on both sides to close the molds, and ensuring the accuracy and stability of the molds 3 on both sides during the closing process to avoid deformation of the forged valve body;

[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 make reciprocating motion in the die 3, and through multiple extrusions and releases, an internal space is formed in the valve body forged in the die 3;

[0064] S5, controlling the cutter mechanism 9 to rotate around the axis of the second extrusion column 8 so that a spherical inner cavity is formed in the valve body;

[0065] S6, controlling the first extrusion column 5 and the second extrusion column 8 to move away from the forged valve body, and then controlling the two dies 3 to separate, and removing the forged valve body;

[0066] S7. After forging, the valve body is slowly cooled to room temperature, and then subjected to solution treatment, quenching and tempering heat treatment processes;

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

[0068] Quenching: Rapidly 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℃ and maintain the temperature for 10-30min to eliminate the residual stress generated during the quenching process and improve the toughness and stability of the material;

[0070] S8, trimming the valve body after the processing in step S7 to remove excess edge material, and then polishing and grinding the inside and outside of the valve body to improve the aesthetics of the valve body molding to complete the processing of the valve body.
