Description

Technical Field

[0001] This utility model belongs to the field of thermal shaping technology for long ears, specifically a thermal shaping fixture for long ears. Background Technology

[0002] In modern mechanical manufacturing, controlling the geometric precision of components with "long ears" structures is one of the core aspects of ensuring product performance. These components are widely used in numerous industries such as automotive, aerospace, and construction machinery. The "long ears" structure typically performs critical connection, transmission, or positioning functions, thus placing extremely stringent requirements on their shape, size, and positional accuracy. Hot forming, as an important process for achieving high-precision machining of these structures, requires specialized hot forming fixtures to precisely correct the shape of the "long ears" under hot working conditions, ensuring smooth subsequent assembly and reliable operation of the entire machine.

[0003] For a long time, the traditional hot forming fixtures used in the industry have gradually revealed insurmountable drawbacks in actual production. On the one hand, the old fixtures use the method of inserting a column into the hole of the ear blank for correction. This method can only affect a local area of ​​the "long ear" and cannot achieve comprehensive and precise control over the overall shape of the "long ear". This results in frequent cases of incomplete ear shaping, causing a large deviation between the actual shape of the "long ear" and the theoretical design shape, which seriously affects the consistency of part quality. On the other hand, when dealing with parts that have undergone significant deformation due to casting, forging, or pre-processing, the old fixture's column is difficult to insert smoothly into the ear hole due to the limitations of the shape and size of the ear hole after deformation. Consequently, it is impossible to perform effective hot forming operations on such parts, which greatly restricts the continuity of production and the adaptability to parts in different states, and increases the cost and time consumption in the production process.

[0004] Therefore, a thermal shaping jig for long ears is proposed to address the above problems. Utility Model Content

[0005] To address the problems mentioned in the background art, this utility model provides a long-ear thermal shaping fixture, which can individually push and shape multiple opposite directions of the ear, and the size can be adjusted according to actual needs. This allows it to flexibly meet the thermal shaping needs of long-ear parts of different specifications and degrees of deformation, significantly improving the quality, efficiency, and production flexibility of thermal shaping of long-ear parts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermal shaping jig for long ears, including an operating table; The surface of the operating table is equipped with a multi-directional pushing component.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figures 1 to 6As shown, this utility model provides a thermal shaping jig for long ears, including an operating table 1; The surface of the operating table 1 is equipped with a multi-directional pushing component 2. The multi-directional pushing component 2 includes a main body groove block 21 installed on the upper surface of the operating table 1, a snap-fit ​​block 22 slidably connected to the surface of the main body groove block 21, and a pushing plate 1 23, a lower pressure plate 24, a side panel 25, an upper abutment plate 26, an abutment plate 27, a pushing plate 28, a limiting block 1 29, a limiting block 210, and a limiting block 3 211 for multi-directional pushing. Push plate 23 is slidably connected to a limiting groove inside the main body slot 21. The lower pressure plate 24 is set on the upper surface of the main body slot 21. Limiting block 29 is installed on the upper surface of the operating table 1. Side panel 25 is slidably connected to the inside of limiting block 29. Limiting block 210 is installed on the upper surface of the operating table 1. Abutment plate 27 is slidably connected to the inside of limiting block 210. Limiting block 311 is installed on the upper surface of the operating table 1. Upper abutment plate 26 and push plate 28 are both slidably connected to the inside of limiting block 3211. This achieves simultaneous shaping of multiple surfaces of the long ear part, breaking through the limitations of traditional single-direction shaping. The cooperation between the main body slot 21 and the fixtures in various directions can apply force to the part from multiple angles, ensuring more comprehensive shaping and providing precise guidance for the movement of each component, avoiding deviation during the shaping process and ensuring the directional stability of the force.

[0019] The upper abutment plate 26 and the second push plate 28 are arranged vertically inside the third limiting block 211. They can apply force to different height areas on the same side of the long ear part, realize the layered shaping of the three-dimensional structure of the part, adapt to the complex contour features of the part, and avoid the local shaping failure caused by the action of a single height.

[0020] The bottom surface of the lower pressure plate 24 is symmetrically equipped with abutment rods 212, which can concentrate the force on specific parts when pressure is applied to the part through the rod-shaped structure, thereby enhancing the local shaping effect. The symmetrical layout can ensure uniform pressure distribution, avoid new deformation of the part due to uneven force, and at the same time reduce the contact area between the lower pressure plate 24 and the part, reducing the risk of surface damage caused by friction or extrusion, thus balancing the shaping effect and the surface quality of the part.

[0021] The shapes of push plate 23, snap-fit ​​block 22, side panel 25, upper abutment plate 26, abutment plate 27 and push plate 28 are respectively adapted to the corresponding surfaces of the long ear parts, so that the force can be evenly distributed on the surface of the parts, avoiding damage to the parts caused by local stress concentration. At the same time, the close contact can ensure that each surface can be accurately pushed to the theoretical position, greatly improving the shaping accuracy, especially suitable for long ear structures with complex shapes.

[0022] The surface of the operating table 1 is equipped with a multi-faceted drive assembly 3. The multi-faceted drive assembly 3 includes a hydraulic cylinder 31 installed on the upper surface of the main body slot block 21, a plurality of hydraulic cylinders 32 evenly installed on the upper surface of the operating table 1, a hydraulic cylinder 33 for driving, and a lower abutment plate 34. The telescopic end of hydraulic cylinder 31 is connected to the lower pressure plate 24. The telescopic ends of multiple hydraulic cylinders 32 are respectively connected to the push plate 23, the snap block 22, the side panel 25, the upper abutment plate 26, the abutment plate 27, and the push plate 28. Hydraulic cylinder 33 is installed on the bottom surface of the operating table 1. The lower abutment plate 34 is slidably connected to the bottom surface of the operating table 1 and is connected to the telescopic end of hydraulic cylinder 33. The hydraulic drive provides stable power and can accurately control the shaping force, effectively solving the problems of inadequate shaping and narrow applicability of traditional fixtures. It improves the shape accuracy and shaping efficiency of long-ear parts. At the same time, the drive of each component is independently controllable, which can realize step-by-step or synchronous shaping, improving the operational flexibility and applicability of the fixture.

[0023] Limiting block 4 35 is installed on the bottom surface of the operating table 1. The lower abutment plate 34 is slidably connected inside the limiting block 4 35. The limiting block 4 35 on the bottom surface of the operating table 1 plays a precise guiding role for the sliding of the lower abutment plate 34, ensuring that the lower abutment plate 34 moves along a preset trajectory under the drive of the hydraulic cylinder 3 33, and avoiding deviation of the force direction caused by the offset of the lower abutment plate 34.

[0024] Among them, the structures of hydraulic cylinder 1 31, hydraulic cylinder 2 32 and hydraulic cylinder 3 33 are existing technologies, and their working principles are well-known technologies. The appropriate model is selected according to the actual use.

[0025] Working principle and process: First, place the long ear part to be shaped stably in the main body slot 21 on the operating table 1. With visual inspection or simple tooling assistance, ensure that the part is roughly in the correct position in the main body slot 21, laying the foundation for subsequent multi-directional precise shaping. Start the multi-faceted drive assembly 3. With the power of each hydraulic cylinder, drive the relevant parts of the multi-directional push assembly 2 to move to the initial working position. For hydraulic cylinder 2 32, control the movement of its extension and retraction ends respectively, and precisely drive push plate 1 23 to slide along the limiting groove opened inside the main body groove 21. The snap block 22 slides on the surface of the main body groove 21, the side panel 25 slides inside the limiting block 1 29, the upper abutment plate 26 and push plate 2 28 slide inside the limiting block 3 211, and the abutment plate 27 slides inside the limiting block 2 210, so that these parts gradually approach the corresponding surface of the long ear part and maintain a suitable initial distance from the surface of the part. Control the extension end of hydraulic cylinder 31 to drive the lower pressure plate 24 to move slowly downward. The abutment rod 212 installed on the bottom surface of the lower pressure plate 24 also moves accordingly and approaches the corresponding part of the part. At the same time, operate the hydraulic cylinder 33 installed on the bottom surface of the operating table 1 to push the lower abutment plate 34 to slide along the inside of the limit block 35 and move upward, so that the lower abutment plate 34 also approaches the corresponding surface of the part. Under the premise that the thermal environment meets the requirements of the forming process, each hydraulic cylinder continues to operate according to the preset program and pressure parameters. Hydraulic cylinder 2 32 continues to push push plate 1 23, snap block 22, side panel 25, upper abutment plate 26, abutment plate 27, and push plate 28. Since the shapes of these components are adapted to the corresponding surfaces of the long-ear part, they can accurately contact the surface of the part and apply thrust. Hydraulic cylinder 1 31 drives the lower pressure plate 24 with the abutment rod 212 to apply force downward to the part. Hydraulic cylinder 33 drives the lower abutment plate 34 to apply force upward to the part. By applying appropriate forces simultaneously from the six surfaces of the long-ear part, all six surfaces of the part are pushed to their theoretical positions, thereby achieving precise thermal forming of the long-ear part and effectively correcting the shape deviations generated during the thermal processing. During the forming process, limit block 1 29, limit block 2 210, limit block 3 211, and limit block 4 35 play a limiting and guiding role in the sliding of the corresponding components, ensuring the accuracy of the forming action.
