Description

Technical Field

[0001] This invention relates to the field of engineering machinery technology, and in particular to a material and casting system for welding a rock-drilling hammer tip with high resistance to large thickness. Background Technology

[0002] Rock hammer tips, as key wear-resistant and impact-resistant components in mining, construction, and tunneling projects, are typically used in repeated contact and impact with high-strength materials such as rock and concrete. They require excellent wear resistance, impact resistance, and a certain degree of weldability. With increasing construction intensity and the development of larger equipment, hammer tip designs are gradually evolving towards greater thickness, more complex structures, and longer service life.

[0003] For example, prior art CN119593464A discloses an underwater rock drilling hammer, including an outer frame, a hammer body, a hammer head assembly, a lifting claw, and a lifting device. The hammer head assembly is located inside the lower end of the outer frame, the hammer body is slidably connected inside the outer frame, the lifting claw is located on the upper part of the outer frame for lifting the hammer body, and the lifting claw is connected to the lifting device for providing power. The outer frame includes an outer frame body, with vertical slide rail grooves on both sides inside the outer frame body; multiple outer frame body waist hoops are connected at equal intervals on the outer side of the outer frame body; an arc-shaped baffle is connected to the lower end of the outer frame body; and a top limiting device is connected to the upper end of the outer frame body through an outer frame bolt and nut assembly, with a top limiting frame connected to the middle of the top limiting device.

[0004] Existing technologies rarely consider grain boundary orientation in the quality inspection of rock-grinding hammer tips, and do not judge the stability of the internal structure of the rock to be ground based on grain boundary orientation, resulting in insufficient comprehensiveness of the inspection. In order to solve the common problems in this field, this invention was made. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of current methods by proposing a material and casting system for welding high-strength, thick-walled grinding hammer tips.

[0006] To overcome the shortcomings of the prior art, the present invention adopts the following technical solution:

[0010] Furthermore, the casting and molding module includes a mold, a casting unit, and a clamping unit. The mold includes a sampling part and a working part. The working part is shaped like a rock hammer tip and is used for the actual work of grinding the rock hammer tip.

[0011] Furthermore, the heat treatment module includes a quenching furnace, a cooling unit, and a tempering furnace. The quenching furnace is used to quench the initial product and heat it to the austenitic temperature. The cooling unit is used to cool the quenched initial product. The tempering furnace is used to temper the cooled initial product at high temperature to obtain the finished product.

[0012] Furthermore, the quality inspection module includes a cutting unit, a grain boundary orientation detection unit, a strength detection unit, and a defect detection unit. The cutting unit is used to sample the finished grinding hammer tip according to the location of the sampling part, thereby cutting the finished grinding hammer tip into a cut grinding hammer tip and a sample. The grain boundary orientation detection unit is used to detect the orientation of the grain boundaries inside the sample in space. The strength detection unit is used to detect the hardness and impact toughness of the cut grinding hammer tip. The defect detection unit includes an ultrasonic flaw detection unit and a surface defect detection unit. The ultrasonic flaw detection unit is used to detect whether there are internal defects in the cut grinding hammer tip, and the surface defect detection unit is used to detect whether there are surface defects in the cut grinding hammer tip.

[0013] Furthermore, the grain boundary orientation detection unit detects the spatial orientation of grain boundaries within a sample by including the following steps:

[0014] STEP 1, Polish the sample;

[0015] STEP2 involves electrolytic etching of the polished sample to remove the residual strain layer on the sample surface and etch the grain boundaries, thereby exposing the true grain structure.

[0016] STEP3: Clean and dry the sample;

[0017] STEP4: Scan the sample using a scanning electron microscope equipped with an EBSD probe;

[0018] STEP5: Use EBSD analysis software to extract relevant data on grain boundary orientation.

[0019] Furthermore, the system's workflow includes the following steps:

[0021] S2, the melting module melts the pretreated raw materials to form an alloy liquid;

[0022] S3, the casting and forming module casts the alloy liquid into a preliminary product, which is then used to grind the tip of a rock hammer.

[0023] S4, the heat treatment module heats the initial product and obtains the finished grinding rock hammer tip.

[0026] The beneficial effects achieved by this invention are: 1. By using advanced technologies and equipment such as Rockwell hardness tester, Charpy impact tester, industrial ultrasonic flaw detector and image recognition technology, efficient and accurate detection of the quality of grinding rock hammer tips is achieved, ensuring a dual improvement in production efficiency and product quality.

[0027] 2. By considering grain boundary orientation to measure the quality of the finished product, compared with the traditional metallographic method that only considers grain size and shape, it can more accurately measure the stability of the internal structure of the finished product and improve the comprehensiveness of quality indicators.

[0028] 3. The hammer tip material contains 13% manganese and 2% chromium, which can form high-manganese austenitic cast steel. By appropriately adding rare earth and cobalt, the grains can be refined and the solid solution effect can be improved to increase toughness, thereby greatly improving the service life of the hammer tip.

[0033] Figure 4 This is a graph showing the relationship between the hardness of the cut rock hammer tip and the hardness parameters of the cut rock hammer tip according to the present invention. Detailed Implementation

[0034] The following specific embodiments illustrate the implementation of the present invention. Those skilled in the art can understand the advantages and effects of the present invention from the content disclosed in this specification. The present invention can be implemented or applied through other different specific embodiments, and various details in this specification can also be modified and changed based on different viewpoints and applications without departing from the spirit of the present invention. Furthermore, the accompanying drawings of the present invention are for simple illustrative purposes only and are not depictions of actual dimensions; this is stated beforehand. The following embodiments will further describe the relevant technical content of the present invention in detail, but the disclosed content is not intended to limit the scope of protection of the present invention.

[0035] Example 1: According to Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment provides a casting system for welding high-strength, relatively thick grinding rock hammer tips, including a raw material pretreatment module, a melting module, a casting and forming module, a heat treatment module, and a quality inspection module. The raw material pretreatment module is used to pretreat the raw materials for casting the grinding rock hammer tips. The melting module is used to melt the pretreated raw materials to form an alloy liquid. The casting and forming module is used to cast the alloy liquid into a preliminary product of the grinding rock hammer tip. The heat treatment module is used to heat treat the preliminary product to obtain the finished grinding rock hammer tip. The quality inspection module is used to perform quality analysis on the finished product based on its strength data, defect data, and grain boundary orientation.

[0036] Furthermore, the raw material pretreatment module includes a raw material screening unit, a drying and dehumidification unit, and an automatic batching unit. The raw material screening unit is used to screen raw materials of different purities, the drying and dehumidification unit is used to remove surface moisture from the screened raw materials, and the automatic batching unit is used to add a specified amount of processed raw materials to the smelting module according to the set raw material ratio.

[0037] Specifically, the raw material screening unit uses image recognition technology to screen metal raw materials of different purities.

[0038] Furthermore, the smelting module includes a heating unit, a stirring unit, and a purification unit. The heating unit is used to heat and melt the raw materials, the stirring unit is used to stir the molten alloy, and the purification unit is used to remove impurities from the molten alloy.

[0039] Specifically, the impurity removal unit can remove harmful gases through an inert gas purging device.

[0040] Furthermore, the casting and molding module includes a mold, a casting unit, and a clamping unit. The mold includes a sampling part and a working part. The working part is shaped like a rock hammer tip and is used for the actual work of grinding the rock hammer tip. The sampling part is used for sampling and quality inspection by the quality inspection module. The clamping unit is used to fix the mold. The casting unit is used to pour the alloy liquid into the mold to obtain the initial product.

[0041] Furthermore, the heat treatment module includes a quenching furnace, a cooling unit, and a tempering furnace. The quenching furnace is used to quench the initial product and heat it to the austenitic temperature. The cooling unit is used to cool the quenched initial product. The tempering furnace is used to temper the cooled initial product at high temperature to obtain the finished product.

[0042] Specifically, by heating the initial product to the austenitic temperature and then cooling it, the microstructure of the initial product is transformed sequentially into austenite (during the heating process) and martensite (formed during the cooling process, a structure with high strength and hardness), thereby strengthening and hardening the initial product. By tempering the cooled initial product, residual quenching stress is eliminated, toughness is improved, and crack resistance is enhanced.

[0043] Furthermore, the quality inspection module includes a cutting unit, a grain boundary orientation detection unit, a strength detection unit, and a defect detection unit. The cutting unit is used to sample the finished grinding hammer tip according to the location of the sampling part, thereby cutting the finished grinding hammer tip into a cut grinding hammer tip and a sample. The grain boundary orientation detection unit is used to detect the orientation of the grain boundaries inside the sample in space. The strength detection unit is used to detect the hardness and impact toughness of the cut grinding hammer tip. The defect detection unit includes an ultrasonic flaw detection unit and a surface defect detection unit. The ultrasonic flaw detection unit is used to detect whether there are internal defects in the cut grinding hammer tip, and the surface defect detection unit is used to detect whether there are surface defects in the cut grinding hammer tip.

[0044] Specifically, hardness testing can be achieved using a Rockwell hardness tester, and impact toughness testing can be achieved using a Charpy impact testing machine. The methods for testing the hardness and impact toughness of the grinding rock hammer tip are existing technologies and will not be elaborated here. The ultrasonic flaw detection unit can be an industrial ultrasonic flaw detector, which can detect internal defects including but not limited to pores and cracks. The surface defect detection unit can identify surface defects using image recognition technology. The methods for detecting internal and surface defects mentioned above are existing technologies and will not be elaborated here.

[0045] Furthermore, the grain boundary orientation detection unit detects the spatial orientation of grain boundaries within a sample by including the following steps:

[0046] STEP 1, Polish the sample;

[0047] STEP2 involves electrolytic etching of the polished sample to remove the residual strain layer on the sample surface and etch the grain boundaries, thereby exposing the true grain structure.

[0048] STEP3: Clean and dry the sample;

[0049] STEP4: Scan the sample using a scanning electron microscope equipped with an EBSD probe;

[0050] STEP5: Use EBSD analysis software to extract relevant data on grain boundary orientation.

[0051] Specifically, the EBSD analysis software can be Oxford Instruments or TSL OIM.

[0052] Furthermore, the system's workflow includes the following steps:

[0053] S1, the raw material pretreatment module pretreatments the raw material for casting the rock hammer tip.

[0054] S2, the melting module melts the pretreated raw materials to form an alloy liquid;

[0055] S3, the casting and forming module casts the alloy liquid into a preliminary product, which is then used to grind the tip of a rock hammer.

[0056] S4, the heat treatment module heats the initial product and obtains the finished grinding rock hammer tip.

[0057] S5, the quality inspection module, performs quality inspection on the finished product and determines whether the quality is qualified.

[0058] Specifically, the quality inspection module determines the quality of the finished product by calculating its quality indicators. The higher the quality indicator, the better the quality of the finished product. The quality indicators are calculated according to the following formula:

[0059]

[0060] Wherein, Quality is the quality index, HARD is the hardness parameter of the cut rock hammer tip, IT is the impact toughness parameter of the cut rock hammer tip, e is the natural constant, VG is the grain boundary orientation uniformity of the sample, V is the volume of the cut rock hammer tip, v is the total volume of internal defects in the cut rock hammer tip, S is the surface area of ​​the cut rock hammer tip, and s is the surface area of ​​external defects in the cut rock hammer tip. This surface area is obtained by the surface defect detection unit through image recognition technology.

[0061] "hard" refers to the hardness of the drilled rock hammer tip after cutting (measured in HRC).max The maximum value within the reference hardness range, hard min The minimum and maximum values ​​are set by those skilled in the art with reference to industry standards and existing grinding rock hammer tips, representing the minimum value within the reference hardness range. Excessive hardness can easily lead to microcracks and brittle fracture, resulting in poor weldability. Conversely, insufficient hardness can cause wear and deformation. When the hardness falls within the reference range, the quality of the grinding rock hammer tip is considered optimal. This achieves the following: when hard is greater than the maximum value of the reference hardness range, the larger hard is, the closer the hardness parameter is to 0. This is achieved by setting... This achieves the following: when hard is less than the minimum value of the reference hardness range, the smaller hard is, the closer the hardness parameter is to 0. When hard is within the reference range, the hardness parameter takes the maximum value, which is 1. At the same time, the piecewise function is set so that the impact of hard being greater than the reference range on HARD is less than the impact of hard being less than the reference range. This is because the harm caused by excessively low hardness is greater than the harm caused by excessively high hardness.

[0062] like Figure 4 As shown, Figure 4 This is a graph showing the relationship between the hardness (hard) of the cut rock hammer tip and the hardness parameter (HARD) of the cut rock hammer tip, assuming a reference hardness range of 50 to 60.

[0063] it represents the impact toughness of the cut rock hammer tip (unit: kJ / m). 2 ), it min To reference the minimum impact toughness, it max For reference, the maximum and minimum values ​​of impact toughness are set by those skilled in the art with reference to industry standards and existing grinding rock hammer tips. When the impact toughness is too high, it often means a decrease in strength and hardness, while when the impact toughness is too low, it is brittle and prone to cracking and brittle fracture. The setting principle of the impact toughness parameter IT is the same as that of HARD, and will not be elaborated here.

[0064] N represents the total number of grain boundaries in the sample, which is obtained from EBSD (EBSD's grain boundary identification criterion is that an orientation difference ≥10° between grains is considered a grain boundary), θ n Let vθ be the orientation angle of the nth grain boundary, obtained through EBSD, and vθ be the average orientation angle of all grain boundaries. max The theoretical maximum value of the orientation angle (180 degrees) is determined by setting... It is beneficial to obtain the grain boundary orientation uniformity based on the mean of the difference between each orientation angle and the average orientation angle. The larger the difference, the smaller the grain boundary orientation uniformity, the more inconsistent the grain orientation, the more unstable the internal structure of the sample, and the worse the impact resistance. By setting IT*ln(e+VG), it is beneficial to use IT and VG to jointly characterize the impact resistance. Furthermore, by setting the logarithm and letting the value of the logarithm increase from 1 (achieved through ln(e)), it is beneficial to make the contribution of IT to the impact resistance greater than that of VG, so that IT can be used as the main criterion for judging the impact resistance, and VG can be used as the secondary criterion.

[0065] Specifically, v can be obtained through an ultrasonic flaw detection unit, and s can be obtained through image recognition technology.

[0066] Specifically, by setting the Quality parameters as described above, each item between the plus and minus signs has a value range of 0 to 1, thus maintaining a relatively balanced contribution of various parameters to the quality index.

[0067] Specifically, the quality inspection module determines whether the quality is qualified by comparing the quality index with the quality index threshold. When the quality index is greater than the quality index threshold, it is considered qualified. The quality index threshold can be obtained by those skilled in the art through quality analysis of various grinding rock hammer tips on the market and obtaining the corresponding quality index, and selecting the minimum value among them as the quality index threshold.

[0068] Specifically, the thickness of the hammer tip is 300mm.

[0069] The beneficial effects of this solution are as follows: 1. By using advanced technologies and equipment such as Rockwell hardness testers, Charpy impact testing machines, industrial ultrasonic flaw detectors, and image recognition technology, efficient and accurate testing of the quality of grinding rock hammer tips is achieved, ensuring a dual improvement in production efficiency and product quality.

[0070] 2. By considering grain boundary orientation to measure the quality of the finished product, compared with the traditional metallographic method that only considers grain size and shape, it can more accurately measure the stability of the internal structure of the finished product and improve the comprehensiveness of quality indicators.

[0071] Example 2: This example should be understood as including all the features of any of the foregoing examples, and further improving upon them. It also includes a system for removing impurities and reinforcing the casting process of a grinding rock hammer tip, comprising a vibration source, a fixing device, and a control module. The vibration source is used to generate low-frequency sound waves. The vibration source can be an eccentric wheel motor, a piezoelectric transducer, or an electromagnetic excitation device. The fixing device is used to fix the vibration source to the outer wall of the mold. The control module is used to control the vibration time and vibration frequency.

[0072] The system operates during the initial solidification stage after the molten alloy is poured into the mold by the casting unit. The system's workflow includes the following steps:

[0073] 1. The control module starts the vibration source, which applies a low-frequency vibration signal to the outer wall of the mold. The frequency of the low-frequency vibration signal is 50 to 500 Hz.

[0074] Second, the vibration is transmitted into the molten alloy through the outer wall of the mold;

[0075] 3. Under the action of vibration, the grains of the alloy liquid break and re-nucleate;

[0076] Specifically, grain fracture and re-nucleation are beneficial for refining the microstructure and for reinforcing the tip of the grinding rock hammer;

[0077] IV. Impurities are precipitated onto the surface of the alloy liquid under the action of vibration, thus removing impurities from the surface of the alloy liquid;

[0078] 5. After the vibration ends, the molten alloy continues to cool.

[0079] Specifically, the vibration time is approximately 15 seconds.

[0080] Specifically, although high-frequency sound waves have short wavelengths and strong directionality, they attenuate very quickly in the alloy liquid and are not easy to transmit into the interior of the alloy liquid. Low-frequency sound waves (50 to 500 Hz) have stronger penetrating power and their energy is easier to propagate into the interior of the alloy liquid. At the same time, the first 15 seconds of cooling are the most critical stage of primary crystal nucleation and dendrite growth. Applying disturbances at this time can have the greatest impact on grain distribution and impurity movement paths.

[0081] Specifically, compared to the existing natural solidification method, this solution applies vibration during the solidification process, which is beneficial for refining grains and removing impurities, thus improving the quality of the grinding hammer tip. Meanwhile, conventional impurity removal methods typically use ultrasonic vibration, which is difficult to implement in this solution due to the high temperature of the molten alloy and the poor penetration of ultrasound waves within the molten alloy. This solution uses low-frequency acoustic vibration, which is beneficial for refining grains and removing impurities. Furthermore, because low-frequency acoustic waves have high penetration, the vibration source does not need to directly contact the molten alloy, enabling non-contact acoustic input and extending the equipment's lifespan.

[0082] The beneficial effects of this embodiment are as follows: This solution uses low-frequency acoustic vibration to process the grains, which is beneficial for refining the grains and removing impurities. At the same time, the vibration source does not need to directly contact the alloy liquid, which is beneficial for achieving non-contact acoustic input and improving the service life of the equipment.

[0083] Example 3: This example should be understood as including all the features of any of the foregoing examples, and further improving upon them. It also includes a material for the grinding rock hammer tip made using the casting system described above, which is composed of the following components in the following mass ratio: 1.25% carbon, 13% manganese, 2% chromium, 10% cobalt, 0.15% rare earth, 0.25% silicon, 0.8% molybdenum, and 72.55% iron.

[0084] The beneficial effects of this embodiment are: the hammer tip material contains 13% manganese and 2% chromium, which can form high-manganese austenitic cast steel. By appropriately adding rare earth and cobalt, the grains can be refined and the solid solution effect can be improved to increase toughness, thereby greatly improving the service life of the hammer tip.

[0085] The above-disclosed content is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Therefore, all equivalent technical changes made based on the description and drawings of the present invention are included within the scope of protection of the present invention. Furthermore, the elements therein can be updated as technology develops. The above units are merely examples, and those skilled in the art can adopt corresponding units according to actual needs when implementing this solution.
