Description

Technical Field

[0001] The invention relates to the technical field of hot die forging, in particular to a flange hot die forging hydraulic equipment. Background Art

[0002] Flange, also known as flange flange or flange; Flange is a part that connects shafts to each other and is used to connect pipe ends; There are many ways to produce flanges, mainly including stamping, hot die forging, cutting flanges and rolling flanges; Among them, hot die forging is the most commonly used method for producing flanges, which involves placing the heated blank in a forging die and forging it through a die forging device; The hot die forging process mainly includes heating, die forging, cooling and other steps; Since the flanges produced by hot die forging have the characteristics of fine crystal structure and high strength, although the price is relatively high, due to its good quality, it is often used to produce high-quality flanges;

[0003] The commonly used die forging device is mainly a hot die forging press. The existing hot die forging press is equipped with three sets of forging dies, namely, a hammer die, a shaping die and a punching die. When forging the heated high-temperature billet, the staff first places the heated high-temperature column billet on the forging die, so that the forging hammer forges the high-temperature column billet into a pancake-shaped billet through the hammer die, and then transfers the pancake-shaped billet to the shaping die, so that the forging hammer forges the pancake-shaped billet into the required flange shape through the shaping die, and finally transfers the flange-shaped billet to the punching die for forging and punching to obtain the required flange rough billet;

[0004] Since flanges of different sizes require dies of different sizes, the corresponding forging dies must be replaced when flanges of different sizes need to be processed; however, after the forging die completes one forging, it absorbs a lot of heat due to contact with the high-temperature billet, making the forging die in a high-temperature state, so it is necessary to stop the machine and wait until the forging die cools to a safe temperature before replacing it; thus, the subsequent flange production is delayed, greatly reducing the production efficiency of flange hot die forging;

[0005] In view of this, in order to overcome the above technical problems, the present invention proposes a flange hot die forging hydraulic equipment to solve the above technical problems. Summary of the invention

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] like Figures 1 to 8 As shown, a flange hot die forging hydraulic equipment according to the present invention comprises a base 1; the upper end of the base 1 is fixedly connected to a frame 11; a forging hammer 12 is arranged between the base 1 and the frame 11; the forging hammer 12 is fixedly connected to the frame 11 through a hydraulic cylinder 121; a concave die 212 is installed on the upper end of the base 1,

[0031] A rotating frame 2, wherein the rotating frame 2 is rotatably connected to the upper end of the base 1; a driving motor 21 is installed inside the base 1; the driving motor 21 is used to drive the rotating frame 2 to rotate; a through groove 211 is provided on the upper end surface of the rotating frame 2; the die 212 is slidably and sealedly connected in the through groove 211; a slot 213 is provided on the side wall of the rotating frame 2; a connecting groove 214 is provided on the side wall of the die 212, which is opposite to the slot 213; an insert rod 215 is slidably and sealedly connected in the slot 213; a cavity 13 is provided inside the base 1; a mounting plate 131 is slidably and sealedly connected in the cavity 13; the mounting plate 131 is connected to the bottom of the cavity 13 through a hydraulic push rod 132; a punching rod 133 is fixedly connected to the upper end of the mounting plate 131; a circular groove 216 is provided on the lower end of the die 212, which is opposite to the punching rod 133.

[0032] Preferably, a rectangular groove 14 communicating with the cavity 13 is provided on one side of the base 1; a baffle 141 is provided at the notch of the rectangular groove 14; the baffle 141 is rotatably connected to the upper end wall of the rectangular groove 14 via a torsion spring; the mounting plate 131 is made of silica material; a push groove 134 is provided at the lower end of the mounting plate 131.

[0033] Preferably, a guide frame 15 is installed on one side of the frame 11 close to the driving motor 21; a steel cable 151 is provided on one side of the guide frame 15; one end of the steel cable 151 passes over the guide frame 15 to the inside of the frame 11; one end of the steel cable 151 close to the hydraulic cylinder 121 is fixedly connected to a steel ring 152; a hook 153 is fixedly connected to the upper end of the forging hammer 12; a U-shaped plate 154 is fixedly connected to the lower end of the steel cable 151; the U-shaped plate 154 is in sliding contact with the rotating frame 2;

[0034] During operation, since flanges of different sizes require dies of different sizes, the corresponding forging dies must be replaced when flanges of different sizes need to be processed; however, after the forging die completes one forging, the forging die absorbs a large amount of heat due to contact with the high-temperature billet, causing the forging die to be in a high-temperature state, so it is necessary to stop the machine and wait until the forging die cools down to a safe temperature before replacing it; this leads to delays in subsequent flange production and greatly reduces the production efficiency of hot die forging of flanges; and there is a special type of flange among flanges, called a blind flange or a blind plate; a blind flange is a special type of flange, which is characterized by having no hole in the middle and is mainly used to seal pipe plugs. When hot die forging the blind flange, only a forging hammer 12 and a die 212 are needed for forging operations; and the die 212 only needs to use two forging dies, a hammer die and a shaping die; therefore, to replace the forging die of the blind flange, only the die 212 of two sets of forging dies need to be replaced;

[0035] In this regard, the present invention sets a rotating frame 2. When the die 212 needs to be replaced, the die 212 to be replaced is placed in the through slot 211 of the rotating frame 2 away from the base 1, and then the driving motor 21 is controlled to drive the rotating frame 2 to rotate to the upper end surface of the base 1. At this time, the used die 212 located on the upper end surface of the base 1 is driven by the rotating frame 2 to rotate in a direction away from the base 1, so that flanges of different sizes can be immediately replaced and produced without waiting for the forging die to cool to a safe temperature, which greatly saves the replacement time and improves the production efficiency of flange hot die forging.

[0036] In the initial state, the punching rod 133 is located in the cavity 13, and the user puts the hammer pressing die and the female die 212 of the shaping die required for the blind flange forging into the through slots 211 at both ends of the rotating frame 2; since the upper end surface of the female die 212 is provided with a flange, the rotating frame 2 can support the female die 212 through the flange at the upper end of the female die 212 to prevent the female die 212 from falling from the through slot 211 of the rotating frame 2; then the rotating frame 2 is controlled to rotate, so that the rotating frame 2 drives the female die 212 with the hammer pressing die installed in the through slot 211 to rotate in the direction close to the base 1, so that the female die 212 of the hammer pressing die of the rotating frame 2 rotates to the center position of the base 1, and at this time, the female die 212 of the hammer pressing die is located directly below the forging hammer 12; driven by the rotating frame 2 The circular groove 216 at the lower end is directly opposite to the upper end of the cavity 13 that passes through the base 1. Then the user controls the hydraulic push rod 132 to push the punching rod 133 upward through the mounting plate 131, so that the punching rod 133 can extend out of the cavity 13 and expose the upper end surface of the base 1, so that the punching rod 133 exposed from the base 1 is inserted into the circular groove 216 of the die 212. At this time, the upper end surface of the punching rod 133 and the cavity floor of the die 212 are in the same plane. Then, the heated high-temperature column blank is placed into the die 212 of the hammer die using a clamp, and then the hydraulic cylinder 121 is controlled to descend, so that the hydraulic cylinder 121 pushes the forging hammer 12 close to the die 212 of the hammer die, so that the forging hammer 12 first contacts with the high-temperature column blank, so that the high-temperature column blank is squeezed by the forging hammer 12 and The high-temperature column blank is deformed and enters the female die 212 of the hammer pressing die, so that the high-temperature column blank is pressed into a pancake shape; when the high-temperature column blank is completely in the female die 212, the hydraulic cylinder 121 is first controlled to pull the forging hammer 12 up, and then the hydraulic push rod 132 is controlled to push the punching rod 133 into the concave cavity of the female die 212 of the hammer pressing die, so that the pancake-shaped blank in the hammer pressing die can be pushed out of the female die 212 by the punching rod 133, so that the user can use pliers to clamp and take out the pancake-shaped blank; at this time, the hydraulic push rod 132 is first controlled to pull the punching rod 133 into the cavity 13, and then the drive motor 21 is controlled to drive the rotating frame 2 to rotate, so that the rotating frame 2 drives the female die 212 of the shaping die to rotate in the direction close to the base 1, until the lower end of the female die 212 of the shaping die When the circular groove 216 is directly opposite to the punching rod 133, the driving motor 21 stops, and the user controls the hydraulic push rod 132 again to push the punching rod 133 into the circular groove 216 at the lower end of the female die 212 of the shaping mold; at this time, the user puts the cake-shaped blank clamped by the clamp into the female die 212 of the shaping mold, and then controls the hydraulic cylinder 121 to push the forging hammer 12 to press the cake-shaped blank into the female die 212 of the shaping mold, thereby obtaining a blind flange rough blank, and pushes the punching rod 133 again, so that the punching rod 133 pushes the blind flange rough blank out of the female die 212 of the shaping mold, and the user uses the clamp to clamp it out and put it on the conveying steel belt of the conveying system, so that the conveying system conveys the forged blind flange rough blank to the next processing step;

[0037] When the high-temperature column blank is pressed into the die 212, the forging pressure applied by the forging hammer 12 to the high-temperature column blank is too high, which increases the metal fluidity of the high-temperature blank forged into the die 212, thereby forcing the metal of the high-temperature blank to fill all the details of the die 212, resulting in the metal forming a closer contact point with the inner surface of the die 212, thereby increasing the risk of adhesion; if the high-temperature blank has too much adhesion to the inner surface of the die 212, the pushed pancake-shaped blank will drive the die 212 to extend upward out of the through slot 211; in order to ensure that the pancake-shaped blank can be effectively pushed out of the die 212 by the punching rod 133, the present invention provides a slot 213, so that after the die 212 is placed in the through slot 211 of the rotating frame 2, the user can rotate the die 21 2, so that the connecting groove 214 of the side wall of the die 212 can be aligned with the slot 213 of the side wall of the rotating frame 2, and then the insert rod 215 is inserted into the connecting groove 214 through the slot 213, so that the die 212 and the rotating frame 2 are fixedly connected through the insert rod 215; so that when the punching rod 133 pushes the high-temperature blank with excessive adhesion on the inner surface of the die 212 to extend out of the die 212, the high-temperature blank drives the die 212 adhered to it to rise, but because the insert rod 215 blocks the die 212 through the groove wall of the connecting groove 214, it is prevented from driving the die 212 to extend out of the through groove 211 by the high-temperature blank, so as to ensure that the high-temperature blank in the die 212 quickly extends out of the die 212 under the push of the punching rod 133, and ensure that the present invention can operate normally and stably;

[0038] In the initial state, a storage rack is installed on one side of the frame 11 close to the guide frame 15, and the U-shaped plate 154 is located in the storage rack; when it is necessary to replace the concave die 212 of other sizes, the user first uses a tool such as a clamp to pull out the plug 215 in the slot 213, and then controls the hydraulic cylinder 121 to pull the forging hammer 12 up, so that the forging hammer 12 drives the hook 153 to approach the steel ring 152 at the lower end of the steel cable 151. At this time, the user uses the clamp to pull the steel cable 151 down. The steel ring 152 at the end is clamped and hung on the hook 153 of the forging hammer 12; then the U-shaped plate 154 is removed and clamped on the rotating frame 2, so that the upper end surface of the U-shaped plate 154 contacts the lower end surface of the flange of the die 212, and then the hydraulic cylinder 121 is controlled to push the forging hammer 12 down, so that the forging hammer 12 pulls the steel ring 152 through the hook 153 to drive the steel cable 151 to extend downward, so that the other end of the steel cable 151 pulls the U-shaped plate 154 fixed to it. The mold plate 154 rises, so that the U-shaped plate 154 can push the die 212 out of the through groove 211 through the flange of the die 212 and be located above the rotating frame 2. At this time, the hydraulic cylinder 121 is controlled to shrink. At the same time, the user uses a traction tool to pull the die 212 pushed out by the U-shaped plate 154 to be lowered from one side of the rotating frame 2. Then the die 212 is removed and placed aside to cool naturally. Do not put it in cold water for rapid cooling. Sudden temperature changes may cause fatigue of the mold material, which means that the material will become brittle or lose its strength and toughness, and even cause the mold to crack, deform or fall off on the surface, thereby affecting the service life and accuracy of the mold; then put the die 212 of the required size into the through groove 211, and insert the insertion rod 215 again. When the two die 212 are replaced, the user puts the U-shaped plate 154 on the storage rack again, and then removes the steel ring 152 hanging on the hook 153;

[0039] By setting the mounting plate 131 to be made of silica material, the heat transferred by the stamping plate in contact with the high-temperature blank can be blocked by the mounting plate 131 and will not be transferred to the hydraulic push rod 132, thereby reducing the temperature of the hydraulic push rod 132 and preventing the hydraulic push rod 132 from being damaged by heat; by setting the rectangular groove 14 connected to the cavity 13, it is convenient for the user to open the rectangular groove 14 by flipping the baffle 141, so that the user can replace the stamping rod in the cavity 13 through the rectangular groove 14, so that the practicality of the present invention is further improved; a pushing groove 134 is provided at the lower end of the mounting plate 131 to facilitate the hydraulic push rod The pushing end of the rod 132 penetrates into the pushing groove 134, that is, the hydraulic push rod 132 is aligned with the mounting plate 131, thereby ensuring that the mounting plate 131 and the hydraulic push rod 132 can maintain good centering. This centering helps the push rod to apply force evenly, avoids offset or deformation between the hydraulic push rod 132 and the mounting plate 131 due to misalignment, and improves the pushing effect of the hydraulic push rod 132 on the punching rod 133; and the hydraulic push rod 132 is located in the pushing groove 134, which can help the contact between the hydraulic push rod 132 and the mounting plate 131 to be more stable, further improving the pushing effect of the hydraulic push rod 132.

[0045] During operation, when punching a non-blind flange, the user first places the concave mold 212 of the hammering mold and the shaping mold into the through groove 211 of the rotating frame 2, controls the driving motor 21 to drive the rotating frame 2 to rotate until it is parallel to the guide frame 15, and then inserts the flip plate 22 into the square groove 241 of the rotating shaft 24 through the square ends at both ends, and rotates the rotating frame 2 to prevent the concave mold 212 on the rotating frame 2 from blocking the installation of the convex mold 222 on the flip plate 22. At this time, the slide groove 221 of the flip plate 22 is located at the end of the flip plate 22 away from the frame 11, and the slide groove 221 of the flip plate 22 faces upward; then the user flips the card plate 242 downward so that the card plate 242 is blocked at the notch of the square groove 241.

[0046] After the flip plate 22 is installed, the user puts the punch 222 of the punching die into the slide groove 221 on the surface of the flip plate 22. Since the upper end of the punch 222 is also fixed with a flange, the punch 222 is clamped in the end of the slide groove 221 of the flip plate 22 through the flange, and the end of the punch 222 away from the flange contacts the swivel 23. The swivel 23 is rotated so that the swivel 23 can be threadedly connected with the end of the punch 222 away from the flange. At this time, the installation of the punch 222 is completed. At this time, the control electromagnetic sheet 273 is energized so that The electromagnetic sheet 273 can generate magnetic force and absorb the connecting rod 271 to squeeze the connecting spring 272 into the groove 27, so that the connecting rod 271 extends out of the positioning groove 28 and drives the bevel gear ring 26 to descend, so that the bevel gear ring 26 can approach the bevel gear shaft 261 below under the drive of the connecting rod 271, until the bevel gear ring 26 and the bevel gear shaft 261 are meshed. At this time, the driving motor 21 is controlled to rotate, so that the driving motor 21 can drive the bevel gear shaft 261 to rotate through the bevel gear ring 26 on the surface of the connecting rod 271. The bevel gear shaft 261 drives the worm 17 to rotate through the bevel gear 18 group, so that the rotating worm 17 can drive the worm 17 meshing with it to rotate, so that the worm wheel 16 drives the flip plate 22 to rotate through the rotating shaft 24 fixed to it, so that the flip plate 22 drives the punch 222 to rotate in the direction close to the frame 11, until the flip plate 22 rotates 90°, so that the flip plate 22 is in a vertical state, and then the electromagnetic sheet 273 is controlled to be de-energized, so that the connecting rod 271 extends out of the groove 2 under the push of the connecting spring 272 7 and inserted into the positioning groove 28. Since the worm wheel 16 and the worm 17 have a self-locking function, it is possible to prevent the flip plate 22 rotated to a vertical state from flipping over and hitting the rotating frame 2 under the action of gravity, thereby preventing the rotating frame 2 and the flip plate 22 from being damaged, thereby improving the safety of the present invention. Subsequently, the driving motor 21 is controlled to drive the rotating frame 2 to rotate, so that the rotating frame 2 drives the hammer pressing die to the upper end of the base 1, so that the hammer pressing die is located directly below the forging hammer 12. At this time, the user puts the high-temperature column blank into the hammer pressing die;After the forging hammer 12 is controlled to forge the high-temperature column blank into a pancake shape, the pancake-shaped high-temperature column blank is clamped, and then the driving motor 21 is controlled to drive the rotating frame 2 to drive the shaping die to rotate to the bottom of the forging hammer 12, and then the pancake-shaped blank is placed in the shaping die. After the forging hammer 12 is controlled to forge and shape the pancake-shaped blank, the flip plate 22 drives the punch 222 in the slide 221 to be located directly above the die 212 of the shaping die, and the punch 222 and the die 212 are in contact with each other. At this time, the hydraulic cylinder 121 is controlled to push the forging hammer 12 down. The forging hammer 12 pushes the punch 222 to insert into the die 212, so that the punch 222 can cooperate with the die 212 and punch the flange blank formed in the die 212, thereby obtaining the required non-blind flange rough blank, and then the electromagnetic sheet 273 is energized, so that the drive motor 21 drives the flip plate 22 to rotate 90° upward, so that the punch 222 is away from the die 212, and the flip plate 22 is away from the rotating plate, so that the user can take out the non-blind flange rough blank and transport it to the next processing step for processing. ;
