Description

Technical Field

[0001] The invention belongs to the technical field of multi-layer retaining ring processing equipment, and in particular relates to a ring-shaped winding forming equipment. Background Art

[0002] The multi-layer spiral retaining ring is an axial fastener, which is used to limit the axial movement of parts on the shaft. Traditional retaining rings are mostly made by stamping technology. During manufacturing, they need to be stamped on a complete plate according to the pre-designed size model. This production process is suitable for mass production, with relatively low cost, low requirements for design and process level, and relatively mature technical research. However, the stamping process will cause a great waste of plate raw materials, and the ordinary retaining rings produced are not accurate enough, and the load bearing and impact resistance are low, and the fatigue life is low. Generally, they can only be installed once, and a new retaining ring must be replaced after the predetermined life is reached. It cannot be installed and used repeatedly.

[0003] With the continuous development of industrial technology and the aerospace industry, the performance requirements for engine components are increasing, and increasingly stringent requirements are being placed on the engine hub gear retaining rings required for them. In particular, the relatively special working conditions of aircraft engines place higher requirements on the strength, impact resistance, elasticity and toughness, fatigue strength and number of repeated installations of retaining rings. Traditional ordinary retaining rings are not suitable for aircraft engines due to their structural defects. Therefore, a new type of spiral retaining ring with better performance was born, which brought new challenges to the manufacturing process. Summary of the invention

[0004] In view of this, the hot forming method of titanium alloy provided by the present invention solves the technical problems that the alloy material of the multi-layer spiral retaining ring is bent along the thin sheet direction on the existing ordinary lathe, and it needs to be compressed on the inside and extended on the outside, and it is difficult to wind it into a ring shape, and the product size accuracy is difficult to control.

[0005] A ring-shaped winding forming device, suitable for processing steel strip blanks into aviation spiral retaining rings, comprises a controller and a housing, the housing is equipped with a digital display lifting and feeding system connected to the controller, the digital display lifting and feeding system is provided with a main shaft, a first movable shaft and a second movable shaft, the main shaft is fixed and the positions of the first movable shaft and the second movable shaft are adjustable, wherein:

[0006] The rotating end of the main shaft extending out of the housing is installed with a first mold, the end of the first movable shaft extending out of the housing is installed with a second mold, and the end of the second movable shaft extending out of the housing is installed with a third mold;

[0007] The digital display lifting and feeding system is controlled by a controller to adjust the relative positions of the first moving axis, the second moving axis and the main axis respectively, and under the action of the first mold, the second mold and the third mold, the steel strip blank can be processed into a spiral retaining ring.

[0008] The technical beneficial effects of the present invention are:

[0009] The present invention adopts the second mold, the third mold and the first mold to perform processing based on the principle of three points forming a circle. Through accurate tensioning and guiding of the workpiece, a three-axis compound motion system is adopted. The rotation of the main shaft is similar to the rotation of the first movable shaft and the second movable shaft, providing power and guidance, and realizing the winding pitch and winding diameter of the spiral retaining ring for aviation. In the process of the mold pressing the workpiece, the workpiece is driven to rotate by friction and the workpiece winding function is realized at the same time. In the rolling process, the steel strip blank is formed with uniform force, the material utilization rate is high, the forming efficiency is high, and the size and technical requirements of the parts can be effectively guaranteed.

[0017] like Figure 1 The ring-shaped winding forming equipment shown is suitable for processing steel strip blanks into aviation spiral retaining rings, including a controller and a housing. The housing is equipped with a digital display lifting and feeding system that is connected to the controller in communication. The digital display lifting and feeding system is a system in the prior art. The digital display lifting and feeding system is provided with a main shaft, a first movable shaft and a second movable shaft. The main shaft is fixed and the positions of the first movable shaft and the second movable shaft are adjustable.

[0018] The rotating end of the main shaft extending out of the housing is installed with a first mold, the end of the first movable shaft extending out of the housing is installed with a second mold, and the end of the second movable shaft extending out of the housing is installed with a third mold. A radially symmetrical arc groove is left on the side of the housing, and the arc groove serves as a moving path of the digital display lifting and feeding system in the digital display lifting and feeding system. The digital display lifting and feeding system is controlled by a controller to adjust the relative positions of the first movable shaft, the second movable shaft and the main shaft respectively, and under the action of the first mold, the second mold and the third mold, the steel strip blank can be processed into a spiral retaining ring. The core of the present invention is that the second mold, the second mold and the first mold roll the steel strip blank according to the principle of three points forming a circle.

[0019] Furthermore, the controller is equipped with a human-machine interactive display screen. According to the actual processing conditions, the relative positions of the first movable axis and the second movable axis can be manually adjusted, and the fixed arc feeding mechanism in the digital display lifting and feeding system drives the first movable axis and the second movable axis to move in the above-mentioned arc groove respectively.

[0020] As a specific implementation scheme provided in this case, the first movable axis and the second movable axis have the same rotation direction, and the rotation directions of the first movable axis and the second movable axis are opposite to the rotation direction of the main axis. Reverse rotation rolling can improve the efficiency of spiral retaining ring rolling.

[0021] Furthermore, the first mold, the second mold and the third mold have the same structure and are all arranged with an I-shaped roller structure, wherein the first model is circumferentially provided with a first groove, the second model is circumferentially provided with a second groove, and the third model is circumferentially provided with a third groove, the widths of the first groove, the second groove and the third groove are all adapted to the steel strip blank, and the height of the steel strip blank is greater than twice the height of the first groove, which is convenient for the installation of the steel strip blank in the initial position and can be assembled in the second groove and the third groove. Since the mold grooves of the three molds are aligned in the vertical plane, the two fixed arc feeding mechanisms respectively drive the first moving axis and the second moving axis to move toward the main shaft in a mirrored manner, and the first mold is driven by the main shaft to rotate forward, and the second mold and the third mold are reversed to press the steel strip blank for rolling. Generally, a plurality of steel strip blanks are conveyed by a conveying device matched in the prior art, and the conveying device is controlled by a controller to control the conveying and time intervals. After the rolling is completed, the rolled steel strip blank is removed by a mechanical gripper or manually. It should be pointed out that the sizes of the second groove and the third groove are the same as that of the first groove to avoid shaking of the steel strip blank during the rolling process.

[0022] As a specific implementation provided in this case, the spindle is located below the lowest movable position of the first movable axis and the second movable axis, and the final processing positions of the first movable axis and the second movable axis are symmetrically arranged with the spindle as the center. When the fixed arc feeding mechanism can drive or adjust the first movable axis and the second movable axis to the final processing position respectively, the notch of the first groove can be aligned with the notches of the second groove and the third groove respectively. Preferably, the first mold is detachably mounted on the rotating end of the spindle, such as by key connection or by means of a nut, the second mold is detachably mounted on the rotating end of the first movable axis, and the third mold is detachably mounted on the rotating end of the second movable axis, to accommodate the processing of workpieces of different sizes.

[0023] As a specific implementation method provided in this case, the controller is preset with a mold position data table, which includes a first initial position and a first final position of the first movable axis relative to the main axis, a second initial position and a second final position of the second movable axis relative to the main axis when processing different types of spiral retaining rings, the first initial position and the second initial position are used for the steel strip blank to be assembled in the second groove and the third groove, and the first final position and the second final position are used for the second mold and the third mold to roll the steel strip blank under the support of the first mold;

[0024] The controller obtains the size parameters of the current spiral retaining ring, and queries the first initial position and the second initial position that match the size parameters of the current spiral retaining ring in the mold position data table. At this time, the steel strip blank is conveyed. After the steel strip blank is embedded in the second groove and the third groove, it moves to the first final position and the second final position. At this time, the steel strip blank can be pressed by the cooperation of the three molds, so that the first mold, the second mold and the third mold can roll the current spiral retaining ring according to the principle of three points forming a circle.

[0025] How it works

[0026] The second die, the third die and the first die are processed based on the principle of three points forming a circle. The corresponding die is selected according to the width-to-thickness ratio of the steel strip blank. The sum of the groove depths of the second die, the third die and the first die when pressed together is less than the height of the steel strip blank to ensure the feeding requirements. At the first initial position and the second initial position, the steel strip blank is output, and the steel strip blank is supported by the first groove of the first die. At the first final position and the second final position, the steel strip blank is tightly clamped, and the first moving axis and the second moving axis begin to rotate clockwise and the main shaft rotates counterclockwise. The steel strip blank is rolled for a certain period of time. After the rolling is completed, the first moving axis and the second moving axis return to the first initial position and the second initial position to process the next steel strip blank.

[0027] The above are only specific embodiments of the present disclosure, but the protection scope of the present disclosure is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present disclosure should be included in the protection scope of the present disclosure. Therefore, the protection scope of the present disclosure should be based on the protection scope of the claims.
