Description

Technical Field

[0001] This application relates to the field of ring forging rolling technology, specifically a forging rolling device with quick die change capability. Background Technology

[0002] Forging rolling equipment is a special equipment for processing forging billets into ring forgings. Currently, ring forging rolling technology is mainly achieved through ring rolling mills. Its core is to use conical rollers to radially roll the ring billet to achieve plastic forming by reducing the wall thickness and increasing the diameter, and finally to form the ring forging.

[0003] However, it has been found in the existing technology that, because the existing technology uses an integral mold, it only has a single mandrel processing mold. When it is necessary to change to a different mandrel processing mold for processing, the integral mold usually needs to be replaced, and it is impossible to switch between mandrel processing molds. Furthermore, when replacing a damaged mandrel processing mold, it will take a lot of time, resulting in a long downtime of the equipment, which in turn affects the processing efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a forging rolling device with quick mold changing capability. It has the advantages of enabling rapid switching between different molds, facilitating the replacement of damaged molds, shortening replacement time, and improving processing efficiency. This solves the problems of existing technologies that use integral molds, have only a single mandrel processing mold, cannot achieve switching between mandrel processing molds, and consume a lot of time when replacing damaged mandrel processing molds, resulting in long downtime of the equipment and thus affecting processing efficiency.

[0005] To achieve the above objectives, this application provides the following technical solution: a forging rolling device with quick die change capability, comprising a rotating plate, wherein the upper surface of the rotating plate is provided with equally spaced sliding grooves, a sliding block is slidably connected to the inner wall of each sliding groove, a threaded rod is rotatably connected to the inner wall of each sliding groove, the outer surface of each threaded rod is threadedly connected to the inner wall of the corresponding sliding block, a sliding rod is fixedly connected to the upper surface of each sliding block, a mandrel processing die is sleeved on the outer surface of each sliding rod, and an adjusting bolt is threadedly connected to the inner wall of each sliding rod. Each bolt has a wedge rotatably connected to its bottom end. Each slide rod has a limit rod fixedly connected to its inner wall. Each limit rod has two locking blocks slidably connected to its outer surface. Each limit rod has a spring fixedly installed on both sides. The other end of each spring is fixedly installed to the outer surface of the corresponding locking block. The outer surfaces of each locking block and wedge are slidably connected to the inner wall of the corresponding slide rod. A rotating rod is fixedly installed on the inner wall of the rotating plate. A platform is rotatably connected to the outer surface of the rotating rod. A stepper motor is fixedly connected to the bottom surface of the platform. The output shaft of the stepper motor is fixedly connected to the bottom end of the rotating rod.

[0006] To achieve rapid switching of mandrel machining molds and facilitate the replacement of damaged molds, thereby shortening replacement time and improving processing efficiency, the above solution involves creating a sliding groove on the upper surface of the rotating plate. A sliding block is placed in the sliding groove, and a threaded rod is installed on the inner wall of the sliding groove, connecting it to the sliding block. Rotating the threaded rod adjusts the position of the sliding block. During mold installation, the mandrel machining mold is fitted onto the surface of the sliding rod, and then the corresponding adjusting bolt is rotated. The threaded connection between the adjusting bolt and the sliding rod causes the adjusting bolt to lower the inclined block at the bottom. By contacting the bottom surface of the inclined block with the inclined surface above the locking block, the inclined block can push the locking block open. At this time, the locking block expands outward on the surface of the limiting rod and stretches the spring. The locking block is now located in the annular groove on the inner wall of the mandrel processing mold, realizing the installation of the mandrel processing mold. Conversely, it realizes disassembly. The stepper motor enables the rotating rod to rotate, and the angle of rotation of the rotating rod switches the corresponding mandrel processing mold to the processing position. This device can quickly switch mandrel processing molds and facilitate the replacement of damaged mandrel processing molds, shortening the replacement time and improving processing efficiency.

[0007] Furthermore, two axial conical rollers are provided on the right side of the platform.

[0008] The above scheme involves setting two axial conical rollers on the right side of the platform, which can process both the upper and lower surfaces of the workpiece.

[0009] Furthermore, a mounting frame is fixedly connected to the upper surface of the platform, and a telescopic rod is fixedly installed on the inner wall of the mounting frame.

[0010] The above method fixes the mounting frame to the upper surface of the platform, thus enabling the installation of the mounting frame. The telescopic rod is installed on the inner wall of the mounting frame, and the mounting frame supports and installs the telescopic rod.

[0011] Furthermore, a fixed frame is fixedly connected to the output end of the telescopic rod, and a servo motor is fixedly installed on the inner wall of the fixed frame.

[0012] The above solution involves installing a fixed frame at the output end of the telescopic rod, allowing the fixed frame to move laterally via the telescopic rod, and mounting the servo motor on the inner wall of the fixed frame. The movement of the fixed frame enables the servo motor to move.

[0013] Furthermore, the output shaft of the servo motor is fixedly connected to a drive shaft, and two telescopic rods are fixedly installed on the upper surface of the platform.

[0014] The above scheme fixes the drive shaft to the output shaft of the servo motor and the drive shaft to the output shaft of the servo motor, so that the servo motor can drive the drive shaft to rotate. Through the connection between the fixing bracket and the servo motor, the drive shaft can move laterally, which facilitates the adjustment of the position of the drive shaft. The telescopic rod two is then installed on the upper surface of the platform to realize the installation of the telescopic rod two.

[0015] Furthermore, each of the two telescopic rods is fixedly connected to an L-shaped plate at its output end, and an auxiliary roller is rotatably mounted on the outer surface of each L-shaped plate.

[0016] With the above scheme, an L-shaped plate is installed at the output end of the telescopic rod two, and the L-shaped plate can be moved by the telescopic rod two. An auxiliary roller is set on the outer surface of the L-shaped plate, and the auxiliary roller is rotatably connected to the surface of the L-shaped plate to realize the limiting of the auxiliary roller. The auxiliary roller can assist the drive shaft in processing the workpiece.

[0017] Furthermore, a guide rod is fixedly connected to the left side of each L-shaped plate, and a sleeve is slidably connected to the outer surface of each guide rod.

[0018] The above solution involves setting a guide rod on the left side of the L-shaped plate and a sleeve on the surface of the guide rod, with the sleeve and guide rod forming a sliding connection to limit the movement of the guide rod.

[0019] Furthermore, a limiting frame is fixedly connected to the outer surface of each sleeve, and the bottom surface of each limiting frame is fixedly installed to the upper surface of the platform.

[0020] The above scheme involves installing a limiting frame on the surface of the sleeve and connecting the bottom surface of the limiting frame to the upper surface of the platform to achieve the installation of the limiting frame and the sleeve. Then, through the connection between the sleeve and the guide rod, the movement of the L-shaped plate is limited.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] This forging rolling device with rapid die changing utilizes components such as adjusting bolts, inclined blocks, locking blocks, and springs. The mandrel processing die is fitted onto the surface of a sliding rod. Rotating the adjusting bolt lowers the inclined block, allowing it to contact the inclined surface of the locking block. This enables relative movement between the two locking blocks, stretching the spring and placing the locking block within the annular groove on the inner wall of the mandrel processing die, facilitating rapid installation. A stepper motor rotates a rotating rod, switching the corresponding die to the processing position. This device allows for rapid die switching and easy replacement of damaged dies, reducing replacement time and improving processing efficiency. Rotating the corresponding threaded rod connects the sliding block to the threaded rod, allowing it to slide within the sliding groove. Adjusting the position of the sliding block within the sliding groove allows for adjustment of the positions of the sliding rod and the mandrel processing die. A telescopic rod allows the servo motor and drive shaft to move closer to or further away from the workpiece, facilitating the rolling of different workpiece wall thicknesses.

[0040] This embodiment provides a quick-change forging rolling device. By incorporating components such as adjusting bolts 7, inclined blocks 8, locking blocks 10, and springs 11, the mandrel processing mold 6 is fitted onto the surface of the slide rod 5. Rotating the adjusting bolts 7 causes the inclined blocks 8 to descend, and the inclined surfaces of the bottom of the inclined blocks 8 and the upper inclined surfaces of the locking blocks 10 come into contact, allowing the two locking blocks 10 to move relative to each other. At this time, the springs 11 are stretched, and the locking blocks 10 are located in the annular grooves on the inner wall of the mandrel processing mold 6, achieving quick installation of the mandrel processing mold 6. A stepper motor 26 rotates the rotating rod 12, which... The angle rotation switches the corresponding mold to the processing position, enabling the device to quickly switch molds and facilitate the replacement of damaged molds, shortening the replacement time and improving processing efficiency. By rotating the corresponding threaded rod 3, the sliding block 4 can be connected to the threaded rod 3, thereby allowing the sliding block 4 to slide on the inner wall of the sliding groove 2. Adjusting the position of the sliding block 4 in the sliding groove 2 makes the positions of the sliding rod 5 and the mandrel processing mold 6 on the surface adjustable. The telescopic rod 15 allows the servo motor 17 and the drive shaft 18 to move closer to or further away from the workpiece, facilitating the rolling of the workpiece wall thickness.

[0041] It should be noted that when the adjusting bolt 7 is reversed, the inclined block 8 moves away from the locking block 10. Under the action of the spring 11, the locking block 10 can be reset, thereby allowing the locking block 10 to automatically exit the annular groove on the inner wall of the mandrel processing mold 6. Both the telescopic rod 15 and the telescopic rod 29 are hydraulically driven, which can realize the movement of the drive shaft 18 and the movement of the auxiliary roller 21. The mandrel processing mold 6 fitted on the surface of the slide rod 5 are molds of different specifications. When using the mold, the corresponding mold can be rotated to the processing position by the stepper motor 26 to realize the mold switching. The stepper motor 26 can realize the angle rotation of the rotating rod 12.

[0042] The working principle of the above embodiments is as follows:

[0043] During installation, the mandrel machining mold 6 is fitted onto the surface of the slide rod 5. Rotating the adjusting bolt 7 lowers the inclined block 8, allowing the inclined surface at the bottom of the inclined block 8 to contact the inclined surface above the locking block 10, enabling the two locking blocks 10 to move relative to each other. At this time, the spring 11 is stretched, and the locking blocks 10 are located in the annular groove on the inner wall of the mandrel machining mold 6, achieving rapid installation of the mandrel machining mold 6. The stepper motor 26 rotates the rotating rod 12, and the angle rotation of the rotating rod 12 switches the corresponding mold to the machining position. This device enables rapid mold switching while facilitating repair of damaged molds. The mold replacement can be shortened, the replacement time can be shortened, and the processing efficiency can be improved. By rotating the corresponding threaded rod 3, the sliding block 4 can be connected to the threaded rod 3, so that the sliding block 4 can slide on the inner wall of the sliding groove 2. Adjusting the position of the sliding block 4 in the sliding groove 2 makes the position of the sliding rod 5 and the mandrel processing mold 6 on the surface adjustable. The position of the drive shaft 18 can be adjusted by the telescopic rod 15. The position of the L-shaped plate 20 and the auxiliary roller 21 can be adjusted by setting the telescopic rod 29. With the axial tapered roller 25, it is convenient to process the ring blank to achieve plastic forming.
