Description

Technical Field

[0001] This invention belongs to the field of forging die inspection technology, and in particular relates to an inspection tool for forging dies. Background Technology

[0002] Forging dies are the core equipment for metal plastic forming processes. The dimensional accuracy of the inner wall of the cavity directly determines the shape, size, and mechanical properties of the forging product.

[0003] As forging structures become increasingly complex and precise, forging die cavities are often designed with irregular curved surfaces, deep cavities, narrow slits, and complex shapes with multiple curvatures. Traditional contact-based inspection methods, such as calipers and micrometers, are limited by the accessibility of the inspection probes, making it difficult to accurately measure the depths of the cavity, corners, and transition areas of curved surfaces. While non-contact optical measurement equipment has the advantage of non-destructive testing, it is prone to problems such as light reflection interference and scanning blind spots when facing highly reflective surfaces on the inner walls of the cavity and narrow enclosed spaces, leading to missing inspection data or a significant decrease in accuracy. At the same time, large forging dies are generally heavy and bulky, and direct inspection not only requires a large inspection platform and specialized hoisting equipment, but the process of handling and positioning the die is also time-consuming and labor-intensive. Furthermore, direct inspection of a single large die often takes several hours, causing long downtime on the production line and seriously affecting production efficiency.

[0004] To address this issue, a testing tool for forging dies is proposed. Summary of the Invention

[0005] The purpose of this invention is to address the above-mentioned problems by providing a testing tool for forging dies.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a testing tool for forging dies, comprising a mounting base, wherein a controller is fixedly connected to the front side wall of the mounting base, and self-locking wheels are fixedly connected to the four corners of the lower side wall of the mounting base, and further comprising:

[0007] A rotating component, located inside the mounting base, enables the simulation component to be moved above the forging die to be tested without disassembling and moving the forging die.

[0008] A gas delivery assembly, disposed on the upper side wall of the rotating assembly, is capable of delivering gas into the simulation assembly;

[0009] An optical detection component is disposed on the upper sidewall of the mounting base for detecting surface data of the simulation component;

[0010] An air intake component, located inside the simulation component, is used to eliminate the gap between the simulation component and the forging die cavity, ensuring the accuracy of the surface data of the simulation component.

[0011] In the aforementioned testing tool for forging dies, the rotating assembly includes a mounting cavity formed inside a mounting base. A rotary motor is fixedly connected to the inner wall of the mounting cavity. The output end of the rotary motor extends out of the mounting cavity and is fixedly connected to a rotating seat. A first electric push rod is fixedly connected to the upper side wall of the rotating seat. An adjusting plate is fixedly connected to the output end of the first electric push rod. A second electric push rod is fixedly connected to the upper side wall of the adjusting plate. A fixed tube is fixedly connected to the output end of the second electric push rod. The lower end of the fixed tube is rotatably connected to a simulation assembly via a sealed bearing.

[0012] In the aforementioned testing tool for forging dies, the simulation component includes an inflation tube rotatably connected to the lower end of a fixed tube. A hollow inflation bladder is fixedly connected to the lower end of the inflation tube. A grid frame is fixedly connected within the interlayer of the wall of the hollow inflation bladder. The grid frame is filled with electrorheological fluid. Multiple conductive posts are inserted into the sidewall of the grid frame. A support plate is fixedly sleeved on the outer wall of the fixed tube. A simulated motor is fixedly connected to the upper sidewall of the support plate. The output end of the simulated motor passes through the support plate and is connected to the inflation tube via a gear ring transmission assembly.

[0013] In the aforementioned testing tool for forging dies, the gas supply assembly includes a gas pump fixedly connected to the side wall of an adjustment plate. The gas supply end of the gas pump is connected to a fixed pipe, and the gas supply end of the gas pump is equipped with an electrically controlled valve. A pressure sensor is connected to the wall of the fixed pipe, and the pressure sensor is electrically connected to a controller. A pressure relief pipe is connected to the wall of the fixed pipe, and a pressure relief valve is provided inside the pressure relief pipe.

[0014] In the aforementioned inspection tool for forging dies, the optical inspection component includes an annular slide rail fixedly connected to the upper side wall of the mounting base. A sliding seat is slidably provided outside the annular slide rail. A horizontal plate is fixedly connected to the side wall of the sliding seat. A drive motor is fixedly connected to the upper side wall of the horizontal plate. The output end of the drive motor is connected to the annular slide rail via a gear ring transmission assembly. A first small lead screw linear module is fixedly connected to the upper side wall of the sliding seat. A connecting frame is fixedly connected to the output end of the first small lead screw linear module. The connecting frame has an L-shaped structure. A laser rangefinder is fixedly connected to the upper end of the connecting frame. The laser rangefinder is electrically connected to a controller.

[0015] In the aforementioned inspection tool for forging dies, the air intake assembly includes a sealing disc fixedly sleeved on the outer wall of an air inlet pipe. An air intake chamber is formed inside the sealing disc. A second small lead screw linear module is fixedly connected to the side wall of the air intake chamber. The moving end of the second small lead screw linear module is fixedly connected to a moving plate via a pressure sensor. An air pump is fixedly connected to the upper side wall of the moving plate. The air intake end of the air pump passes through the moving plate and is fixedly connected to a hollow air extraction plate. A sliding port matching the hollow air extraction plate is formed on the lower side wall of the air intake chamber. Multiple air intake holes are formed on the side wall of the hollow air extraction plate, and a filter screen is fixedly connected inside each air intake hole. A flexible hose is fixedly connected to the outlet end of the air pump, and the end of the flexible hose furthest from the air pump is connected to the outside.

[0016] In the aforementioned testing tool for forging dies, a baffle plate is fixedly connected to the side wall of the hollow suction plate, a baffle groove matching the baffle plate is opened on the side wall of the sliding port, and a rubber pad is fixedly connected to the lower side wall of the sealing disc.

[0017] In the aforementioned inspection tool for forging dies, a laser generator is fixedly connected to the side wall of the sealing disc, and multiple laser receivers are fixedly connected to the moving end of the first small lead screw linear module.

[0018] Compared with existing technologies, the advantages of a testing tool for forging dies are:

[0019] 1. By using the set rotating components, gas supply components, and simulation components, when inspecting the inner wall dimensions of the forging die cavity, the cavity of the forging die is simulated and extracted, and optical inspection is carried out in the outside. This can overcome the spatial constraints caused by the complex cavity structure of the original die, eliminate scanning blind spots and data interference caused by deep cavities, narrow gaps, and highly reflective surfaces, and ensure inspection accuracy. At the same time, there is no need to transport, hoist, and position large dies, saving the investment in supporting large inspection platforms and avoiding long-term downtime of the production line due to direct inspection, which significantly reduces the manpower and material costs of inspection. In addition, the extracted cavity model can be flexibly measured from multiple angles, re-inspected multiple times, and compared and analyzed in a laboratory environment. This can not only avoid damage to the original die cavity by the probe during the inspection process, but also significantly improve the inspection efficiency and flexibility.

[0020] 2. By using the suction component, during the process of filling the forging mold cavity with electrorheological fluid to simulate the extraction of the cavity morphology, the gas between the hollow inflatable bladder and the cavity is extracted. This eliminates gaps and air bubbles between the hollow inflatable bladder and the inner wall of the cavity, ensuring that the electrorheological fluid can completely conform to the irregular curved surfaces, deep cavities, and narrow slits of the cavity. This guarantees that the simulated cavity model is highly consistent with the size and shape of the original mold cavity. At the same time, it avoids local bulging or depression of the hollow inflatable bladder caused by gas, preventing model distortion and providing a high-precision morphological reference for subsequent external optical inspection, thereby improving the accuracy and reliability of the inspection data.

[0021] 3. By using a laser generator and laser receiver, after the gas between the hollow inflatable bladder and the cavity is extracted using the suction component, the extraction location is automatically marked. This clearly defines the gas extraction area, preventing the bladder shape at that location from being misjudged as the actual contour of the cavity during subsequent optical measurements. It also quickly distinguishes the bonding boundary between the bladder and the cavity, eliminating the problem of measurement benchmark confusion caused by the lack of markings at the extraction location. This provides a clear reference for optical inspection and further ensures the dimensional accuracy of the forging die cavity simulation extraction. Attached Figure Description

It also includes:

[0031] A rotating assembly 4 is disposed inside the mounting base 1. The rotating assembly 4 includes a mounting cavity 401 formed inside the mounting base 1.

[0032] Gas delivery assembly 15 is disposed on the upper side wall of rotating assembly 4 and can deliver gas into simulation assembly 10.

[0033] An optical detection component 19 is disposed on the upper side wall of the mounting base 1.

A sliding seat 192 is slidably disposed outside the annular slide rail 191. A horizontal plate 20 is fixedly connected to the side wall of the sliding seat 192.

The laser rangefinder 24 is electrically connected to the controller 2 and is used to detect the surface data of the simulation component 10.

[0034] An air intake assembly 25, disposed inside the simulation assembly 10, is used to eliminate the gap between the simulation assembly 10 and the forging die cavity, ensuring the accuracy of the surface data of the simulation assembly 10. The air intake assembly 25 includes a sealing disc 251 fixedly sleeved on the outer wall of the inflation tube 101. A laser generator 36 is fixedly connected to the side wall of the sealing disc 251. Multiple laser receivers 37 are fixedly connected to the moving end of the first small lead screw linear module 22. An air intake chamber 252 is opened inside the sealing disc 251. A second small lead screw linear module 26 is fixedly connected to the side wall of the air intake chamber 252. The moving end of the second small lead screw linear module 26 is fixedly connected to a moving plate 27 through a pressure sensor. An air pump 28 is fixedly connected to the upper side wall of plate 27. The air pump 28's suction end passes through the movable plate 27 and is fixedly connected to a hollow air pump 29. The lower side wall of the suction chamber 252 has a sliding port 30 that matches the hollow air pump 29. A baffle plate 33 is fixedly connected to the side wall of the hollow air pump 29. A blocking groove 34 that matches the baffle plate 33 is opened on the side wall of the sliding port 30. A rubber pad 35 is fixedly connected to the lower side wall of the sealing plate 251. Multiple suction holes are opened on the side wall of the hollow air pump 29, and a filter screen 31 is fixedly connected inside the suction holes. A hose 32 is fixedly connected to the air outlet of the air pump 28. The end of the hose 32 away from the air pump 28 is connected to the outside.

[0035] The operating principle of this invention is explained as follows: The mounting base 1 is moved to one side of the forging mold to be tested. Then, the operator controls the rotary motor 402 to work via an external remote control switch. The rotary motor 402 drives the first electric push rod 6 and the adjusting plate 7 to rotate together via the rotating base 5. The adjusting plate 7 drives the simulation component 10 to move directly above the forging mold to be tested. Then, the operator controls the second electric push rod 8 to work via an external remote control switch. The second electric push rod 8 drives the simulation component 10 to move downward to the set position, so that the simulation component 10 is located inside the forging mold to be tested, and the sealing plate 251 covers the top of the forging mold to be tested (the air supply end of the air pump 151 is a telescopic type). The structure will not affect the lifting and lowering of the simulation component 10. Then, the operator controls the simulation motor 14 to work through an external remote control switch. The simulation motor 14 controls the rotation of the air tube 101 through the gear and ring gear transmission assembly (the gear and ring gear transmission mechanism includes a gear connected to the output end of the simulation motor 14 and a ring gear sleeved on the outer wall of the air tube 101. The simulation motor 14 can drive the air tube 101 to rotate through the meshing of the gear and the ring gear). The air tube 101 will drive the sealing disc 251 and the hollow air extraction plate 29 to rotate to an appropriate angle so that the hollow air extraction plate 29 and the straight area of ​​the inner wall of the forging mold cavity to be tested remain parallel, so as to minimize the impact of the hollow air extraction plate 29 on the simulation component 10.

[0036] Next, the operator sends an electrical signal to the controller 2 via an external remote control switch. Upon receiving the signal, the controller 2 first controls the second small lead screw linear module 26 to operate. The second small lead screw linear module 26, through a pressure sensor, moves the moving plate 27 towards the inner cavity of the forging die. The moving plate 27 moves the air pump 28 and the hollow air extraction plate 29 together. When the hollow air extraction plate 29 contacts the inner wall of the forging die cavity, the controller 2 detects this through a pressure sensor (not shown in the diagram). The controller 2 then stops the second small lead screw linear module 26 from operating. Next, the controller 2 controls the air delivery pump 151 to operate and opens the electronically controlled valve 152. The air delivery pump 151 delivers external gas through the fixed pipe 9 and the inflation pipe 101 to... Inside the hollow air bladder 102, the air bladder 102 is inflated and expands, making it contact the inner wall of the forging mold to be tested. At the same time, the controller 2 also controls the air pump 28 to work. The air pump 28 extracts the air between the hollow air bladder 102 and the forging mold to be tested through the air suction holes on the surface of the hollow air suction plate 29, so that the hollow air bladder 102 is fully in contact with the inner wall of the forging mold to be tested. After the air pressure sensor 16 on the wall of the fixed tube 9 detects that the air pressure inside the hollow air bladder 102 has reached the set threshold (1.5 standard atmospheres), the controller 2 will control the air supply pump 151 and the air pump 28 to stop working at the same time, and control the electrorheological fluid in the interlayer of the hollow air bladder 102 to be energized and solidified. At this time, the hollow air bladder 102 will maintain the same shape as the cavity of the forging mold to be tested.

[0037] Next, controller 2 controls the second electric push rod 8 to move the hollow inflatable bladder 102 upward and away from the forging mold to be tested. Then, controller 2 controls the rotary motor 402 to work. The rotary motor 402 drives the adjusting plate 7 to rotate a certain angle through the rotating seat 5, so that the hollow inflatable bladder 102, which maintains its shape, is located directly above the annular slide rail 191. Then, controller 2 controls the drive motor 21 to work. The drive motor 21 controls the sliding seat 192 to slide along the annular slide rail 191 through the gear ring transmission assembly. The sliding seat 192 drives the laser rangefinder 24 through the first small lead screw linear module 22 to detect the size of the hollow inflatable bladder 102, and sends the detection data to controller 2. Controller 2 sends the data to the receiver in the operator's hand through the wireless transmission module.
