Description

Technical Field

[0001] This invention relates to the field of metal material performance testing technology, specifically a multifunctional metal material testing device. Background Technology

[0002] As core basic materials in strategic fields such as aerospace, high-end equipment manufacturing, and new energy, the mechanical properties, environmental corrosion resistance, and fatigue life of metallic materials directly determine the reliability and service safety of end products. As modern industry develops towards high precision, high load, and extreme working conditions, the requirements for the comprehensive performance of metallic materials continue to increase. Traditional single-parameter, discrete testing devices are no longer able to meet the needs of multi-dimensional performance collaborative testing of materials under complex working conditions.

[0003] After the metal material is manufactured, it needs to undergo comprehensive testing on the final product or samples taken from the product. During friction and wear testing of the metal material, the sliding, rolling, or impact contact between the sample and the wear material continuously generates wear debris. The randomness of debris generation and removal means that completely different results can be obtained under the same parameters, leading to invalid or misleading test results. To solve the problem of wear debris interference, existing technologies commonly use vacuum adsorption to remove and collect it, ensuring accuracy during testing and avoiding secondary contamination. However, this method still has the following problems: For samples made of high-value metallic materials (such as special alloys, precious metal coating materials, etc.), the abrasive shavings generated in the test have extremely high recycling value. Existing technology collects magnetic and non-magnetic abrasive shavings together in the same container. Although there are devices for separating magnetic and non-magnetic abrasive shavings, in actual use, when the abrasive shavings generated in the test are collected in the collection tube, the magnetic and non-magnetic abrasive shavings mix and experience severe friction and collision. They are easily mixed due to electrostatic adsorption, making it impossible to effectively separate the generated strong magnetic and weak magnetic abrasive shavings. This further leads to the need for complex physical sorting processes (such as magnetic separation, eddy current separation, etc.) in the subsequent recycling process. This not only significantly increases the cost and energy consumption of subsequent processing, but may also reduce the purity of the recycled abrasive shavings due to cross-contamination. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional metal material testing device to address the aforementioned issues raised in the background art. For samples made of high-value metal materials (such as special alloys, precious metal coating materials, etc.), the resulting abrasive shavings have extremely high recycling value. Existing technologies collect magnetic and non-magnetic abrasive shavings together in the same container. Although devices exist for separating magnetic and non-magnetic abrasive shavings, in actual use, when the abrasive shavings are collected in the collection tube, the magnetic and non-magnetic abrasive shavings experience intense friction and collision, easily forming a mixture due to electrostatic adsorption. This makes it impossible to effectively separate the generated strong and weak magnetic abrasive shavings, further requiring subsequent recycling processes to rely on complex physical sorting techniques (such as magnetic separation, eddy current separation, etc.). This not only significantly increases the cost and energy consumption of subsequent processing but may also reduce the purity of the recycled abrasive shavings due to cross-contamination.

Without interfering with the friction and wear test, it achieves dynamic separation of magnetic and non-magnetic wear chips, ensuring the accuracy of the test and improving the purity of high-value wear chip recovery.

An adsorption plate is fixedly installed on the inner surface of the slot, and a scraper is slidably connected to the inner surface of the second sliding groove.

[0008] Preferably, the movable adsorption structure further includes a sliding block, the bottom of which is slidably connected to the top of the first sliding groove, and a feed inlet is fixedly installed on the top of the sliding block.

[0009] Preferably, a position sensor is fixedly installed on the outer surface of the feed inlet, the outer surface of the feed inlet is fixedly connected to the other end of the conveying pipe, a moving block is fixedly installed on the outer surface of the sliding block, a limit block is slidably connected to the inner surface of the moving block, and the outer surface of the limit block is fixedly connected to the outer surface of the worktable.

[0010] Preferably, the bottom of the fixed block is fixedly installed with the top of the workbench, the outer surface of the chip collection channel is fixedly installed with the outer surface of the moving block, the bottom of the chip collection channel is fixedly connected to a connecting pipe, and an electric three-way valve is provided on the outer surface of the connecting pipe.

[0011] Preferably, a connecting plate is fixedly connected to the bottom of the movable block, a set of collection boxes are symmetrically fixedly installed on the outer surface of the connecting plate, and a first air pump is provided on the outer surface of the connecting pipe. The outer surface of the first air pump is fixedly installed with the outer surface of the connecting plate.

[0012] Preferably, an air pipe is fixedly connected to the outer surface of the separation box near the lower part, a second air pump is provided on the outer surface of the air pipe, a weak magnetic box is fixedly connected to one end of the air pipe, the outer surface of the weak magnetic box is fixedly installed to the outer surface of the connecting plate, and the top of the weak magnetic box is fixedly installed to the bottom of the second air pump.

[0013] Preferably, the outer surface of each of the electromagnetic three-stage separation components is provided with an anti-static component; it is used to remove static electricity from the stored grinding debris to prevent secondary pollution caused by subsequent airflow.

[0015] Compared with the prior art, the beneficial effects of the present invention are: In this invention, a three-stage electromagnetic separation structure is employed to achieve precise sorting of grinding debris instantaneously. The first stage, a strong magnetic field, efficiently captures strongly magnetic grinding debris. The second stage, an adjustable magnetic field, is designed for the precise separation of weakly magnetic grinding debris. The third stage collects high-purity non-magnetic grinding debris. During this process, the adsorption plate and scraper work together to ensure effective adsorption and smooth removal of magnetic grinding debris. This dynamic separation mechanism eliminates the risk of severe friction and collision between grinding debris of different properties, which would otherwise easily lead to electrostatic adsorption and the formation of a mixture. This fundamentally ensures the high purity and value of the recovered material. Furthermore, by placing the sorting step in advance and integrating it into the experimental process, it eliminates the need for subsequent complex independent sorting processes, thereby significantly simplifying the recovery process and greatly reducing the overall investment in equipment, energy consumption, and costs.

[0016] In this invention, the electromagnetic separation structure does not interfere with the contact between the sample and the grinding material. Combined with the moving adsorption structure, it tracks the test position and promptly draws in the grinding debris. This not only avoids the interference of random grinding debris residue on the test, but also continues the advantage of vacuum adsorption to remove grinding debris, ensuring the stability and reliability of the test results under the same parameters.

The top of the weak magnetic box 227 is fixedly installed on the bottom of the second air pump 226.

[0021] The overall effect achieved by Embodiment 1 is that, before the friction and wear test is started on the workbench 1, the sensing unit of this device, such as... Figure 2As shown, the position sensor 205 is activated to begin initial calibration and continuous monitoring of the clamping position of the metal material sample. When the testing machine starts running and the sample and the mating material enter a friction state, the external controller will simultaneously issue a command to start the first air pump 218 to work immediately, forming a stable negative pressure adsorption force field at the feed inlet 204 of the device. At the same time, the position sensor 205 continuously locks onto and tracks the dynamic contact area of ​​the friction pair, feeding back the real-time position signal to the controller. Based on this signal, the controller drives the electromagnetic linear drive module, causing the sliding block 203 to reciprocate within the first sliding groove 202 through electromagnetic force, thereby driving the feed inlet 204 to achieve intelligent following. The feed inlet 204 can dynamically and continuously adjust its spatial position to ensure that its adsorption end face is always precisely aligned with and covers the instantaneous source of grinding debris. Throughout the tracking process, the sliding unit, through an auxiliary moving component, allows the moving block 209 to slide on the limiting block 208, effectively eliminating gaps and wobbling during movement and ensuring extreme stability and position control accuracy in the tracking process. Thus, the metal grinding debris generated during friction, which is a mixture of magnetic and non-magnetic materials, is effectively captured by the negative pressure of the feed inlet 204 the moment it is generated, preventing its scattering. The grinding debris group is then fed into the negative pressure conveying pipe 206 and converges into the chip collection channel 207. Figure 3 As shown, within the chip collection channel 207, the device performs its crucial magnetic separation function. The controller energizes the set of magnetic adsorption plates 211 pre-embedded in the slot 210, generating an adjustable gradient magnetic field. When the mixed grinding chips flow through this magnetic field, all ferromagnetic metal chips are subjected to a strong magnetic force and are quickly adsorbed and fixed onto the specially designed adsorption plates 211. Non-magnetic metal chips, however, are unaffected by the magnetic field and continue to flow through the channel with the main airflow. Before the non-magnetic metal material mixture falls into the separation box 219, such as... Figure 4 - Figure 5 As shown, the weak magnetic roller 223 is pre-started and establishes a magnetic field. Simultaneously, the servo motor 221 mounted on the U-shaped plate 220 starts working, its output driving the drive gear 222 to rotate. Through the meshing gear system 222, power is synchronously transmitted to the other two driven gears 222, thereby driving the three weak magnetic rollers 223 to rotate synchronously. The falling non-magnetic metal material mixture is first guided by the inclined slide plate 224 and concentrated onto the surface of the rotating weak magnetic roller 223. The material then slides down the roller surface under the action of gravity and roller surface friction. During this process, the weakly magnetic metal material mixed in is adsorbed and captured on the roller surface due to the magnetic field of the weak magnetic roller 223, thus achieving separation. Figure 6As shown, the material is ultimately transported to a dedicated non-magnetic wear debris collection box 215 via a subsequent connecting pipe 216 for temporary storage. Then, the second air pump 226 is activated, causing the air pipe 225 to generate suction while simultaneously closing the weak magnetic roller 223, causing the weak magnetic metal material to fall off. The air pipe 225 then draws the weak magnetic metal material into the weak magnetic box 227. After the friction and wear test is completed, the controller initiates the final wear debris recovery program. This program first cuts off the power supply to the magnetic adsorption plate 211, causing its magnetic field to instantly dissipate, thus releasing the magnetic wear debris from its confinement. Immediately afterwards, the controller simultaneously executes two actions: one is to switch the airflow path via an electric triple-jet switch. The valve 217 opens a new conveying channel for magnetic abrasive debris; secondly, the second electromagnetic drive module is activated to drive a wear-resistant scraper 213 made of titanium alloy to scrape the surface of the adsorption plate 211 along the second sliding groove 212. The titanium alloy scraper 213 ensures extremely high wear resistance and structural strength while avoiding the introduction of impurities due to its own wear. The scraper 213 thoroughly and cleanly scrapes away the magnetic abrasive debris that has been freed from the magnetic force from the surface of the adsorption plate 211. Under the action of gravity and auxiliary airflow, these abrasive debris fall into the connecting pipe 216 below, which has been switched, and are finally transported to the dedicated magnetic abrasive debris collection box 215.

[0022] Preferably, following the technical solution described in Embodiment 1 above, to address the problem of secondary pollution caused by air carrying grinding debris during the subsequent processing of grinding debris, a solution is proposed, specifically, as follows: Figure 6 and Figure 7 As shown: The outer surface of a set of electromagnetic three-stage separation components 2 is provided with an anti-static component 3; it is used to remove static electricity from the stored grinding debris to prevent secondary pollution caused by subsequent airflow. A set of static elimination components 3 includes a liquid storage tank 301. A liquid infusion pipe 302 is fixedly connected to the outer surface of the liquid storage tank 301 near the lower part. A water pump 303 is provided on the outer surface of the liquid infusion pipe 302. A base 304 is fixedly installed at the bottom of the water pump 303. The outer surface of the base 304 is fixedly installed with the outer surface of the separation box 219. One end of the liquid infusion pipe 302 slides through the top of the collection box 215 and extends to the lower part. One end of the liquid infusion pipe 302 is fixedly connected to an atomizing nozzle 305. The outer surface of the liquid storage tank 301 is fixedly installed with the outer surface of the chip collection channel 207.

[0023] The overall effect is that after magnetic and non-magnetic wear debris are separately collected, the system initiates the final dust control procedure, such as... Figure 6 As shown, a micro water pump 303 extracts the special antistatic agent prepared in the storage tank 301 and delivers it to the atomizing unit of the target collection box 215 through the infusion tube 302. At the instant the command to open the cover of the collection box 215 is given, as... Figure 7As shown, the atomizing nozzle 305 sprays milliliters of antistatic agent into the sealed space inside the box in the form of an extremely fine dry mist. This special reagent has extremely high volatility and can quickly vaporize and act on the surface of the grinding debris upon contact. Its core mechanism is to neutralize the electrostatic charge carried on the surface of the grinding debris particles, thereby eliminating the fundamental force that causes the particles to repel each other and easily disperse. After losing electrostatic support, the repulsive force between the grinding debris disappears, and the particles settle naturally under the action of gravity and tend to accumulate stably. Because the amount of reagent is precisely controlled at an extremely low level and evaporates rapidly, the whole process is a completely "dry" operation, with no liquid residue wetting the grinding debris. This fundamentally ensures the original physical state and subsequent utilization value of the recycled material, and effectively solves the problem of grinding debris dispersion that may be caused by the convection of internal and external air when the collection box 215 is opened, eliminating secondary pollution and material loss in this critical link. The base 304 is used to fix the water pump 303.

[0024] The working principle of the entire equipment is as follows: Before the friction and wear test is started, the position sensor 205 of the device is activated, and the clamping position of the metal material sample is initially calibrated and continuously monitored. After the testing machine is running, the sample and the mating material enter a friction state. The external controller synchronously sends a command to start the air pump 218, forming a stable negative pressure adsorption force field at the feed inlet 204. At the same time, the position sensor 205 continuously locks the dynamic contact area of ​​the friction pair and feeds back the real-time position signal to the controller, which drives the electromagnetic linear drive module to make the sliding block 203 reciprocate in the first sliding groove 202, driving the feed inlet 204 to intelligently follow. During this process, the moving block 209 moves through the auxiliary moving component. Sliding on the limiting block 208 eliminates movement gaps and wobbling, ensuring that the adsorption end face of the feed inlet 204 is always precisely aligned with and covers the source of grinding debris. The mixed grinding debris generated by friction is captured by negative pressure at the moment of its formation and gathers to the chip collection channel 207 via the negative pressure conveying pipe 206. The controller powers the magnetic adsorption plate 211 group in the slot 210 to generate an adjustable gradient magnetic field. Magnetic grinding debris is adsorbed and fixed on the adsorption plates 211 on both sides of the channel, while non-magnetic grinding debris is sent to the special collection box 215 for temporary storage via the airflow and connecting pipe 216. Subsequently, the weak magnetic roller 223 is pre-activated and establishes a magnetic field. At the same time, the output end of the servo motor 221 drives the drive gear 222 to rotate, which is connected to the gear 223. Power is transmitted to two other driven gears 222, driving three weak magnetic rollers 223 to rotate synchronously. The falling non-magnetic metal material mixture is guided by the slide plate 224 and transported to the surface of the rotating weak magnetic rollers 223. During this process, the weak magnetic metal material is attracted and captured on the roller surface by the magnetic field of the weak magnetic rollers 223, thus achieving separation. Subsequently, the second air pump 226 is started, causing the air pipe 225 to generate suction and simultaneously closing the weak magnetic rollers 223, causing the weak magnetic metal material to fall. The air pipe 225 then draws the weak magnetic metal material into the weak magnetic box 227. After the test, the controller starts the recovery program, first cutting off the power supply to the magnetic adsorption plate 211. As the magnetic field dissipates, the electric three-way valve 217 is switched to open a new channel. At the same time, the second electromagnetic drive module is activated, driving the titanium alloy wear-resistant scraper 213 to scrape along the second sliding groove 212 for its entire stroke, completely scraping away the magnetic grinding debris. Under the action of gravity and auxiliary airflow, the debris is sent into the magnetic collection box 215. Finally, the dust prevention program is activated. The micro water pump 303 draws out the antistatic agent from the storage tank 301 and sends it to the atomization unit through the infusion pipe 302. The moment the collection box 215 is opened, the atomizing nozzle 305 sprays in an extremely fine dry mist to neutralize the static electricity on the surface of the grinding debris, preventing it from drifting away. The reagent evaporates quickly without residue, ensuring the original state and utilization value of the recovered grinding debris and preventing secondary pollution and material loss.
