Description

Technical Field

[0001] A roll forming device for a blade rolling mill relates to the technical field of roller processing, in particular to the technical field of roll forming of aircraft engine blades. Background Art

[0002] In the field of aero-engine blade manufacturing, the forming quality of blades directly affects the performance and life of the engine. Traditional blade rolling mills often rely on manual adjustment and control when rolling blade raw materials. This method is not only inefficient, but also difficult to ensure accuracy, resulting in low rolling qualification rate of blade raw materials, long trimming cycle, and high labor costs. In addition, the instability of manual operation may also lead to inconsistent blade sizes, affecting the overall performance of the engine. In order to improve the efficiency and quality of blade rolling, this device should be able to realize automatic identification control, reduce manual intervention, thereby saving adjustment time, improving rolling qualification rate, shortening blade trimming cycle, and reducing labor consumption. However, the existing technical solutions still have many deficiencies in terms of automation, precision control, and ease of operation. Although some solutions use automation technology, they still require a lot of manual adjustment and monitoring in actual applications, and cannot completely get rid of manual dependence. At the same time, these solutions also have limitations in the design of roller lifting and drive devices, and cannot meet the requirements of high-precision and high-efficiency rolling. Therefore, developing a new type of blade rolling mill roll forming device to achieve automated, efficient and high-precision blade rolling has become a technical problem that needs to be solved in this field. This device needs to be innovative in structural design to adapt to the complex shape and high-precision requirements of aircraft engine blades, while also ensuring ease of operation and convenience of maintenance.

The hydraulic arm and the hydraulic cylinder are respectively mounted on the upper and lower rolling drive device of the rolling mill, and are connected in an articulated manner. The support seats are respectively bolted to the mounting base for installation and fixation; the support seat and the hydraulic cylinder are connected in an articulated manner; the hydraulic cylinder is the power device of the upper and lower rolling drive device of the rolling mill, and the roll lifting device of the rolling mill provides pressure for the entire roll forming device of the blade rolling mill.

[0006] The roller lifting device is respectively composed of an outer shell, a top block, a supporting device, a crossbeam frame, a connecting beam, a column, a lifting device, a lifting inclined block, a short copper guide rail, an inclined slideway, a driving device, a driving inclined iron, an oil guide groove, a fixed block slider track, a copper guide rail, a slideway, a lug plate, a driving supporting device, a hydraulic cylinder, an axle seat pad, and a fixed pad; The outer shell is where the roller lifting device and the roller upper and lower driving device of the roller mill are placed, and the outer shell is fixed to the mounting base by bolt connection; The slide base is where the driving inclined iron is placed.

Four copper guide rails are placed on both sides above the slide base and below the slide fixing seat, and the copper guide rails are respectively fixed to the slide base and the slide fixing seat by bolt connection. The copper guide rails are the parts that directly contact the driving inclined iron and are the tracks of the driving inclined iron, which are convenient for oil injection and lubrication. Furthermore, the driving inclined iron has the protruding parts on both sides below placed in the grooves of the two copper guide rails, which constrains the longitudinal and vertical movement of the driving inclined iron of the roller lifting device; The ear plate is a connecting piece connecting the driving inclined iron and the hydraulic cylinder. The ear plate is connected to the driving inclined iron by bolts for installation and fixation. Furthermore, the ear plate is hingedly fixed to the hydraulic cylinder.

[0023] Working principle of the present invention: When the hydraulic cylinder is activated and pushes the driving bevel iron, the driving bevel iron moves forward, and the lifting bevel iron in contact with it responds by moving upward. This action causes the rolling drive mechanism of the rolling mill to be pushed upward by the lifting bevel iron until the gears of the rolling drive mechanism and the rolling driven mechanism are fully engaged, ensuring that the rolling block is in the best contact position. Subsequently, when the upper and lower hydraulic cylinders of the rolling drive mechanism of the rolling mill work together, they cause the upper and lower gears of the driving mechanism to rotate in opposite directions. Until it is transmitted to the driven mechanism, causing the driven gear to also rotate in the corresponding direction. During this process, the intermediate forming device starts to operate, and the material is introduced and processed. As the blade blank continues to advance, the forming device continues to work to achieve precise cutting of the blade. This cycle ensures a continuous and efficient production process.
