Description

Technical Field

[0001] This invention relates to the field of aero-engine blade processing equipment technology, specifically to a forging hammer device for aero-engine blade processing. Background Technology

[0002] Aero engines are the core power source of aviation equipment, and their performance directly determines the flight efficiency and reliability of the equipment. As a key load-bearing component of the engine, blades must withstand high temperatures, high pressures, and complex loads, requiring extremely high material strength, precision, and stability. Blade processing is one of the core challenges in aviation manufacturing. Forging technology can significantly improve the density and mechanical properties of blade materials and is a core processing step for high-quality blades. As a key piece of equipment in blade forging, the forging hammer device achieves plastic forming of metal blanks through precise and controllable impact loads, which can efficiently create blade blanks that meet design requirements, laying the foundation for subsequent precision machining. It is an important support for ensuring the mass production and quality of aero engine blades.

[0003] However, the existing blade processing forging hammer device is not convenient for changing the mold required for the forging hammer during use, which requires the staff to spend a lot of time operating it during the production process, thus prolonging the preparation time required for the forging hammer and reducing production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a forging hammer device for aero-engine blade processing. By setting up a replacement part, it solves the problem that existing blade processing forging hammer devices are inconvenient to replace the molds required for forging hammers during use, which leads to workers having to spend a lot of time operating them during production, thus prolonging the preparation time required for forging hammer work and reducing production efficiency.

[0005] To solve the above-mentioned technical problems, the present invention is achieved through the following technical solution: This invention relates to a forging hammer device for processing aero-engine blades, comprising a base, and further comprising: a main body mounted on the base; a replacement part mounted inside the base; a locking part located on the front side of the base; and two bulletproof parts mounted on the base. The replacement part includes a limiting component located inside the base; and a rotating component located inside the base. The limiting component includes a mold located inside the base, the mold having several limiting grooves. The inner wall of the base has several sliding grooves, and the inner walls of each sliding groove are slidably connected to limiting plates. The shapes of the limiting plates are respectively adapted to the limiting grooves.

[0006] Furthermore, the main body includes a frame fixedly connected to the outer wall of the base, a hydraulic cylinder fixedly connected to the inner wall of the frame, and a punching head fixedly connected to the output end of the hydraulic cylinder.

[0007] Furthermore, the locking part includes a connecting component, which is installed on the front side of the base; and a locking component, of which there are two, both of which are located on the front side of the base and are circumferentially distributed.

[0008] Furthermore, the bulletproof part includes an adjustment component disposed outside the mold; and two extrusion components, both of which are located outside the base and are mirror images of each other.

[0009] Furthermore, the rotating assembly includes several springs fixedly connected to the bottom of several limiting plates, the bottom of several springs being fixedly connected to several sliding grooves, a rotating shaft being rotatably connected to the inner wall of the base, several gears being fixedly connected to the outer wall of the rotating shaft, and racks being fixedly connected to the inner walls of several limiting plates. Each limiting plate corresponds to two springs, and the gears mesh with the racks respectively.

[0010] Furthermore, the connecting assembly includes a connecting block fixedly connected to the outer wall of the rotating shaft, and a handle is fixedly connected to the outer wall of the connecting block.

[0011] Furthermore, the locking assembly includes a limiting block 1 fixedly connected to the front side of the base, a sliding groove 2 is provided on the rear side of the connecting block 1, a spring 2 is fixedly connected to the inner wall of the sliding groove 2, the limiting block 2 is slidably connected to the inner wall of the sliding groove 2, the front side of the limiting block 2 is fixedly connected to the spring 2, and the limiting block 2 is adapted to the limiting block 1.

[0012] Furthermore, the adjustment component includes two slide grooves three respectively opened on the left and right sides of the base, and sliders are slidably connected to the inner walls of the two slide grooves three. Limiting strips are fixedly connected to the inner walls of the two sliders, and the two sliders are mirror images of each other.

[0013] Furthermore, the extrusion assembly includes a rotating shaft two rotatably connected to the inner wall of the slider, a connecting block two fixedly connected to the outer wall of the rotating shaft two, an elastic element provided inside the connecting block two, a handle on the front side of the connecting block two, the elastic element including an extrusion block slidably connected to the inner wall of the connecting block two, two springs three fixedly connected to the inner wall of the extrusion block, the side of the two springs three away from the base being fixedly connected to the connecting block two, and the side of the extrusion block near the base having an arc-shaped head.

[0014] The present invention has the following beneficial effects: (1) By setting up a replacement part, when in use, the rotating component drives the gear to rotate, and the gear drives the limiting plate to slide in the slide groove through the rack. After the limiting plate slides out of the limiting groove, the mold is no longer restricted. After replacing the mold, the rotating component resets so that the limiting plate is locked into the limiting groove of the new mold under the action of the elastic element to complete the fixation. The mold can be replaced with simple operation. Through the cooperation of the limiting component and the rotating component, the restriction on the original mold can be quickly released. At the same time, the newly replaced mold can be stably limited and fixed, ensuring the smooth progress of subsequent forging hammer processing. This reduces the time required for device preparation and improves production efficiency.

[0015] (2) By setting a locking part, when rotating, the rotating handle drives the connecting block one and the rotating shaft one to rotate. The limiting block two rotates with the connecting block one and is squeezed into the slide groove two by the limiting block one. Then, under the action of the elastic element, it is locked on the limiting block one. When unlocking, the limiting block two is pulled to slide into the slide groove two. After the connecting block one is unrestricted, it resets. The position of the rotating component can be stably locked. During the mold replacement process, the rotating component will not rotate at will, providing a safe and stable operating environment for the mold to be taken out and installed. At the same time, the locking state can be reliably released without affecting the reset and fixation after the mold is replaced.

[0016] (3) By setting up a bulletproof part, when preparing, the limiting strip is pulled to drive the slider to slide in the slide groove three, so that the limiting strip presses against the blade blank. The connecting block two is rotated to drive the rotating shaft two to rotate. After the extrusion block extrudes the base, it slides into the connecting block two and compresses the elastic element. Under the elastic force of the elastic element, the extrusion block abuts against the base to complete the slider fixation. It can stably limit and fix the blade blank, avoid the blade blank from bouncing up during the forging hammer process, ensure the safety of the forging hammer process, and at the same time, the limiting position can be flexibly adjusted to adapt to the processing needs of blade blanks of various specifications.

[0022] Please see Figure 1 - Figure 7 As shown, the present invention is a forging hammer device for processing aero-engine blades, including a base 101, and further including: a main body 1, which is mounted on the base 101; a replacement part 2, which is mounted inside the base 101; a locking part 3, which is located on the front side of the base 101; and two bulletproof parts 4, both of which are mounted on the base 101.

By setting the replacement part 2, the mold 211 can be replaced with simple operation. Through the cooperation of the limiting component 21 and the rotating component 22, the restriction on the original mold 211 can be quickly released. At the same time, the newly replaced mold 211 can be stably limited and fixed, ensuring the smooth progress of subsequent forging hammer processing. This reduces the time required for device preparation and improves production efficiency.

[0024] The locking part 3 includes a connecting component 31, which is installed on the front side of the base 101; and two locking components 32, both located on the front side of the base 101 and arranged in a circle.

The front side of limit block 224 is fixedly connected to spring 223. Limit block 224 is adapted to limit block 1 321. By setting locking part 3, the position of rotating component 22 can be stably locked, ensuring that rotating component 22 will not rotate randomly during mold 211 replacement, providing a safe and stable operating environment for mold 211 removal and installation, and can reliably release the locking state without affecting the reset and fixation of mold 211 after replacement.

[0025] The bulletproof part 4 includes an adjustment component 41, which is disposed outside the mold 211; and two extrusion components 42, both located outside the base 101 and mirror images of each other. The adjustment component 41 includes two slide grooves 411 respectively opened on the left and right sides of the base 101. The inner walls of the two slide grooves 411 are slidably connected to sliders 412. The inner walls of the two sliders 412 are fixedly connected to limit strips 413. The two sliders 412 are mirror images of each other. The extrusion component 42 includes a rotating shaft 421 rotatably connected to the inner wall of the slider 412.

The side of the pressing block 423 near the base 101 has an arc-shaped head. By setting the anti-bullet part 4, the blade blank can be stably limited and fixed, preventing the blade blank from bouncing during the forging hammer processing, ensuring the safety of the forging hammer processing. At the same time, the limiting position can be flexibly adjusted to adapt to the processing needs of blade blanks of various specifications.

[0026] It should be noted that the hydraulic cylinder 103 in this application is equipped with a corresponding hydraulic pump to drive the hydraulic cylinder 103, thereby ensuring the normal operation of the forging hammer.

[0027] In use, the blade blank can be placed on top of the mold 211, and the limiting strip 413 can be pulled to make the slider 412 slide within the groove 411. At this time, the blade blank can be pressed under the limiting strip 413. Then, the connecting block 422 can be pulled to make the rotating shaft 421 rotate. At this time, the extrusion block 423 will extrude the base 101 and slide into the connecting block 422. At this time, the spring 424 will be compressed and generate elastic force. Subsequently, under the action of the elastic force of the spring 424, the extrusion block 423 will be compressed and generate elastic force. The pressure block 423 abuts against the base 101, thus fixing the slider 412. At this time, the blade blank will be restricted in position by the two limiting strips 413. Then, the hydraulic cylinder 103 can be activated, causing its output end to drive the punch head 104 to hammer downwards, thus completing the forging of the blade blank. When it is necessary to change the mold 211, the handle 312 can be turned, causing the connecting block 1 311 to rotate. At this time, the limiting block 2 324 will rotate accordingly, and finally, the limiting block 2 324 will be pressed by the limiting block 1 321 and slide into the slide groove 2 3. Within 22, spring 223 will compress and generate elastic force. Finally, under the action of the elastic force of spring 223, the limiting block 224 will be locked onto the limiting block 1 321, thus completing the limiting. When connecting block 1 311 rotates, it will drive rotating shaft 1 222 to rotate. At this time, rotating shaft 1 222 will drive gear 223 to rotate. Gear 223 will then drive limiting plate 214 to slide within slide groove 1 213 via rack 224. At this time, spring 1 221 will compress and generate elastic force, causing limiting plate 214 to slide within slide groove 1 213. 4. When sliding, it will slide out of the limiting groove 212. At this time, the mold 211 will lose its restriction. Then, the mold 211 can be pulled out of the base 101. Then, a new mold 211 can be installed. Then, the limiting block 224 can be pulled to slide in the sliding groove 222. At this time, the spring 223 will be compressed and generate elastic force. At this time, the connecting block 1 311 will lose its restriction. At this time, under the action of the elastic force of the spring 1 221, the limiting plate 214 will be driven to be inserted into the limiting groove 212, thereby completing the restriction.
