Description

Technical Field

[0001] The present invention relates to the technical field of noise reduction testing of stamping equipment, and in particular to a noise reduction testing system for security of stamping equipment. Background Art

[0002] With the continuous development of the construction industry, the evolution of the sound in the construction industry has become more and more intense. It is necessary to carry out corresponding noise reduction for the sound generated during the construction process to ensure that the processing personnel have a good processing environment. By monitoring the sound of the stamping equipment during operation, we can understand the collection of all noises generated by the stamping equipment. When the corresponding noise of the stamping equipment occurs, the components of the stamping equipment are monitored to ensure the specificity of the conditions during the noise reduction test of the stamping equipment, thereby providing effective noise reduction for the stamping equipment and ensuring that the processing personnel have a comfortable working environment.

[0003] Existing technologies include the noise reduction system, noise reduction method, and electrical equipment disclosed in the invention patent application with publication number CN109630379A. This application includes: a compressor having a working chamber and a silencer chamber, the working chamber and the silencer chamber being connected; a reciprocating motion device having a piston, the piston being disposed in the silencer chamber; a controller for obtaining compressor noise detection information, and controlling the piston to move in the silencer chamber to form a synthetic jet based on the compressor noise detection information, so as to utilize the blowing and suction process of the synthetic jet to generate noise reduction sound, and perform noise reduction treatment on the noise in the working chamber. Through this application, it is possible to effectively reduce noise according to the different noise characteristics under different compressor working conditions, thereby helping to improve the user experience and also helping to improve the quality of the compressor and the electrical equipment using the compressor.

[0004] With respect to the above scheme, there are the following technical problems: the above invention mainly obtains the noise detection information of the compressor, and then controls the movement of the piston in the silencer chamber to form a synthetic jet, so as to utilize the blowing and suction process of the synthetic jet to generate noise reduction sound. It does not determine the level of the noise during the corresponding operation of the stamping equipment, nor does it monitor the corresponding components of the stamping equipment when the corresponding operating sound of the stamping equipment is detected to be in noise. Therefore, it is impossible to know whether the corresponding noise of the stamping equipment contains components of damaged components, and thus it is impossible to provide unified conditions for the corresponding noise reduction test of the stamping equipment, and it is impossible to obtain effective noise reduction of the stamping equipment, so that the noise of the stamping equipment cannot be effectively reduced, and the adverse effects of the stamping noise are increased. Summary of the Invention

[0005] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a noise reduction test system for stamping equipment security.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solution: The present invention provides a noise reduction test system for stamping equipment security, including: a stamping equipment operation analysis module, which is used to collect noise collection data corresponding to each time period during the operation of the stamping equipment, and analyze to obtain a collection of noise generation conditions corresponding to the operation of the stamping equipment.

[0007] The shock-absorbing equipment testing module is used to place various shock-absorbing devices under the stamping equipment when the noise of the stamping equipment during operation is at a certain level, so as to collect the shock-absorbing data of the various shock-absorbing devices placed under the stamping equipment during the test, and analyze and obtain the shock-absorbing device corresponding to the noise reduction of the stamping equipment.

[0008] The sound insulation equipment testing module is used to place various sound insulation devices under the stamping equipment when the noise of the stamping equipment during operation is at the second degree of noise, collect the sound insulation information of each sound insulation device installed on the stamping equipment during the test, and then analyze and obtain the sound insulation equipment corresponding to the stamping equipment.

[0009] The silencer test module is used to install silencers under the stamping equipment when the noise of the stamping equipment during operation is at the third degree of noise, obtain the silencer data of each silencer installed on the stamping equipment during the test, and analyze the silencer corresponding to the stamping equipment.

[0010] The display terminal is used to display the noise reduction equipment that matches the stamping equipment at each noise generation level.

[0011] Compared with the prior art, the beneficial effect of the present invention is that: the present invention provides a noise reduction test system for stamping equipment security, which analyzes the collection of noise generation conditions that will appear when the stamping equipment is running, and then performs noise reduction tests at various noise levels based on the noise condition collection, and excludes additional situations where the stamping equipment is damaged before the test, thereby ensuring the uniformity of conditions during the noise reduction test of the stamping equipment, and then analyzing the corresponding noise reduction device selection for the stamping equipment at various levels of noise, thereby achieving effective noise reduction of the stamping equipment, and allowing the stamping equipment to obtain the necessary noise reduction at each noise angle, thereby ensuring the comfort of the stamping equipment operating environment in the factory, reducing hearing damage caused by the stamping equipment operating noise, reducing the noise and noisy impact of the stamping equipment noise on the surrounding environment, and ensuring the legality of the factory stamping equipment operation.

[0012] By collecting noise data corresponding to each time period during the operation of the stamping equipment, we analyze the noise generation conditions of the stamping equipment during operation, and then perform a comprehensive test analysis and summary of the noise that will appear in the stamping equipment, so as to ensure that the stamping equipment is effectively noise-reduced and the corresponding environment of the factory during processing is fully maintained. At the same time, when the stamping equipment makes noise, we perform component inspections on the stamping equipment to understand the health of the corresponding components of the stamping equipment in real time, efficiently understand the composition of the stamping equipment noise, and conduct targeted noise reduction tests.

[0013] When the noise level of the stamping equipment during operation is at the first level, the corresponding noise reduction device of the stamping equipment is analyzed to achieve effective noise reduction when the stamping equipment produces the first level of noise, thereby ensuring the standardization of the operation of the stamping equipment.

[0014] When the noise level of the stamping equipment during operation is at the second degree, the analysis results in the upper limit of the sound insulation of the sound insulation equipment corresponding to the stamping equipment, which provides an effective sound insulation option for the stamping equipment, realizes effective noise isolation, and protects the health of processing personnel and residents in the surrounding environment.

[0015] When the noise level of the stamping equipment during operation is at the third degree, the corresponding silencer device of the stamping equipment is analyzed to ensure the comfort of the stamping equipment operating environment in the factory, reduce the hearing damage caused by the noise of the stamping equipment operation, and ensure the compliance of the factory stamping equipment operation.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 As shown, a noise reduction test system for stamping equipment security includes a stamping equipment operation analysis module, a shock absorption equipment test module, a sound insulation equipment test module, a silencing equipment test module, a display terminal and a database.

[0020] The stamping equipment operation analysis module is respectively connected to the shock absorption equipment test module, the sound insulation equipment test module, the database and the silencer equipment test module; the shock absorption equipment test module is respectively connected to the display terminal and the database; the sound insulation equipment test module is respectively connected to the display terminal and the database; and the silencer equipment test module is respectively connected to the display terminal and the database.

[0021] The stamping equipment operation analysis module is used to collect noise data corresponding to each time period when the stamping equipment is running, and analyze it to obtain a collection of noise generation conditions during the corresponding operation of the stamping equipment.

[0022] It should be noted that the purpose of analyzing the noise generation conditions is to more clearly understand the levels of noise generated during the operation of the stamping equipment, to perform a comprehensive analysis and summary of any noise conditions that may occur in the stamping equipment, and to comprehensively reduce the noise generated by the operation of the stamping equipment.

[0023] It should be noted that noise monitoring equipment includes but is not limited to sound level meters, spectrum analyzers and real-time analyzers.

[0024] As an optional implementation, the analysis obtains a collection of noise generation conditions of the stamping equipment during operation. The specific analysis process is as follows: the noise monitoring equipment is used to monitor the sound volume of the stamping equipment during operation, and the noise collection data of the stamping equipment corresponding to each time period during operation are obtained, including sound pressure level and spectrum, and are recorded as A t and B t , t is the number of each time period, t=1,2,……,s, s is any integer greater than 2.

[0025] If (A t <A')∧(B t <B'), the noise presented by the stamping equipment during operation corresponding to the t-th time period is recorded as first-degree noise, and the noise of the stamping equipment during operation is determined to be at first-degree noise, and the corresponding component monitoring of the stamping equipment is performed, and the shock absorption and noise reduction test of the stamping equipment is performed. ∧ is the sum, A' is the set noise reference sound pressure level, and B' is the set noise reference spectrum.

[0026] If (A t >A')∧(B t <B') or (A t <A')∧(B t >B'), the noise presented by the stamping equipment during operation corresponding to the t-th time period is recorded as the second-degree noise, and the noise corresponding to the stamping equipment during operation is determined to be the second-degree noise, and a sound insulation and noise reduction test is performed on the second-degree noise corresponding to the stamping equipment.

[0027] If (A t =A')∧(B t =B'), the noise presented by the stamping equipment during operation corresponding to the t-th time period is recorded as no noise, then it is determined that the stamping equipment does not generate noise during operation, and the corresponding operation monitoring of the stamping equipment is continued.

[0028] If (A t >A')∧(B t>B'), the noise presented by the stamping equipment during operation corresponding to the t-th time period is recorded as the third-degree noise, and the noise corresponding to the stamping equipment during operation is determined to be at the third-degree noise, and a noise reduction test is performed on the third-degree noise corresponding to the stamping equipment.

[0029] The first-order noise, second-order noise and third-order noise corresponding to each time period during the operation of the stamping equipment are statistically analyzed, and a collection of noise generated during the corresponding operation of the stamping equipment is constructed.

[0030] It should be noted that first-degree noise can also be called low-frequency noise, which is usually below 70dB; second-degree noise can also be called medium-frequency noise, which is usually 70dB-90dB; third-degree noise can also be called high-frequency noise, which is usually 90dB-120dB.

[0031] It should be noted that the noise reference sound pressure level and noise reference spectrum are set by professional personnel; the noise reference sound pressure level and noise reference spectrum are used together to judge whether the sound generated by the stamping equipment during operation has formed noise or has exceeded the maximum permissible range of noise.

[0032] As an optional implementation, monitoring of components corresponding to the stamping equipment is performed. The specific implementation process is as follows: When the stamping equipment makes a noise during operation, basic information of each component corresponding to the stamping equipment is obtained, including component wear area and component clearance. This basic information of each component corresponding to the stamping equipment is then imported into the stamping component status assessment model: , where β p is the basic state value of the stamping equipment corresponding to the pth component, p is the number of each component, p=1,2,…,m, m is any integer greater than 2, k' is the set reference component wear area, h' is the set reference component gap, k p is the wear area of ​​the stamping equipment corresponding to the pth component, h p is the component gap of the stamping equipment corresponding to the pth component, and r is the set reference component state evaluation value.

[0033] When the basic state value of each component corresponding to the stamping equipment is 1, it is determined that the components corresponding to the components of the stamping equipment are normal, which indicates that the noise corresponding to the stamping equipment is emitted when the stamping equipment is in a normal state, and the corresponding noise reduction test is performed. If the basic state value of the stamping equipment corresponding to a certain p components is 0, it is determined that the components corresponding to the component of the stamping equipment are abnormal, which indicates that the noise generated by the stamping equipment is related to the cause of the component abnormality, and the corresponding components are replaced, and the above operation process is continued for the replaced stamping equipment.

[0034] It should be noted that the basic information of each component of the stamping equipment is obtained using an industrial endoscope.

[0035] It should be noted that when monitoring the components of the stamping equipment, the purpose is to understand whether the noise generated by the current stamping equipment is due to component damage. If so, the components will be replaced. If the sound volume of the stamping equipment during operation still exceeds the standard after the component replacement, the corresponding noise reduction test will be performed. At the same time, monitoring the status of the stamping equipment is also to ensure the specificity of the noise reduction test of the stamping equipment, and to effectively analyze and summarize additional causes and factors to ensure the effectiveness and accuracy of the noise reduction test.

[0036] It should be noted that the reference component wear, reference component gap and reference component status evaluation values ​​are set by professional personnel; the reference component wear area, reference component gap and reference component status evaluation values ​​are used as reference values ​​to determine whether the corresponding components of the stamping equipment are abnormal.

[0037] By collecting noise data corresponding to each time period during the operation of the stamping equipment, we analyze the noise generation conditions of the stamping equipment during operation, and then perform a comprehensive test analysis and summary of the noise that will appear in the stamping equipment, so as to ensure that the stamping equipment is effectively noise-reduced and the corresponding environment of the factory during processing is fully maintained. At the same time, when the stamping equipment makes noise, we perform component inspections on the stamping equipment to understand the health of the corresponding components of the stamping equipment in real time, efficiently understand the composition of the stamping equipment noise, and conduct targeted noise reduction tests.

[0038] The shock-absorbing equipment testing module is used to place various shock-absorbing devices under the stamping equipment when the noise of the stamping equipment during operation is at a certain level, so as to collect the shock-absorbing data of the various shock-absorbing devices placed under the stamping equipment during the test, and analyze and obtain the shock-absorbing device corresponding to the noise reduction of the stamping equipment.

[0039] It should be noted that each shock-absorbing device includes a shock-absorbing pad, a shock-absorbing spring, an air spring, etc.

[0040] As an optional implementation method, the shock absorption data of each shock absorption device placed when the stamping equipment is tested is collected. The specific collection process is as follows: M1. Obtain the amplitude generated by the stamping equipment corresponding to one-degree noise from the database, and use the amplitude of the highest sound value corresponding to the one-degree noise as the upper limit amplitude reference value of each shock absorption device in the shock absorption and noise reduction test, and set a preset amplitude difference.

[0041] M2. Place each shock-absorbing device in sequence under the stamping equipment, start the stamping equipment at the lowest amplitude, and preset the interval length. After each preset interval length, increase the preset amplitude corresponding to the stamping equipment, collect the actual vibration intensity corresponding to the stamping equipment after each amplitude increase, until the amplitude intensity corresponding to the stamping equipment increases to the upper limit amplitude reference value, stop the test, and summarize the vibration intensity of the stamping equipment after each amplitude increase under the protection of each shock-absorbing device.

[0042] As an optional implementation, the analysis obtains a shock-absorbing device corresponding to the noise reduction of the stamping equipment. The specific obtaining process is as follows: if the degree of reduction in the vibration intensity of the stamping equipment corresponding to each shock-absorbing device is consistent, the stability value of each shock-absorbing device corresponding to the noise reduction is compared with the reference stability value stored in the database. If the stability value of a certain shock-absorbing device corresponding to the noise reduction is greater than or equal to the reference stability value stored in the database, the shock-absorbing device is used as the shock-absorbing device corresponding to the noise reduction of the stamping equipment.

[0043] It should be noted that the stable value of each shock-absorbing device during noise reduction is as follows: the vibration intensity of each shock-absorbing device under the amplitude increasing test of the stamping equipment is obtained, the average value of each vibration intensity is calculated, and the stable value of each shock-absorbing device during noise reduction is obtained.

[0044] If the degree of reduction in the vibration intensity of the stamping equipment by each shock-absorbing device is inconsistent, then according to the amplitude of each shock-absorbing device during the test reduction, the shock-absorbing devices with the highest amplitude reduction value during the test are selected, and the vibration intensity of each shock-absorbing device is arranged in order from low to high. The shock-absorbing device that ranks first in vibration intensity during the test reduction is used as the shock-absorbing device for noise reduction of the stamping equipment.

[0045] When the noise level of the stamping equipment during operation is at the first level, the corresponding noise reduction device of the stamping equipment is analyzed to achieve effective noise reduction when the stamping equipment produces the first level of noise, thereby ensuring the standardization of the operation of the stamping equipment.

[0046] The sound insulation equipment testing module is used to place various sound insulation devices under the stamping equipment when the noise of the stamping equipment during operation is at the second degree of noise, collect the sound insulation information of each sound insulation device installed on the stamping equipment during the test, and then analyze and obtain the sound insulation equipment corresponding to the stamping equipment.

[0047] It should be noted that various sound insulation equipment includes steel plate sound insulation covers, aluminum alloy sound insulation covers and fiberglass sound insulation covers.

[0048] It should be noted that the sound effect difference is set based on the numerical range corresponding to the second-degree noise stored in the database. The highest numerical value corresponding to the second-degree noise is used as the reference value for the sound effect test. The preset sound effect difference will start from the minimum value corresponding to the second-degree noise and increase the sound effect in sequence.

[0049] As an optional implementation, the sound insulation information of each sound insulation device installed in the stamping equipment is collected during the test. The specific collection process is as follows: Y1. The volume range of the second-order noise corresponding to the stamping equipment is obtained from the database, and the highest volume corresponding to the second-order noise is used as the upper limit volume reference value of each sound insulation device in the sound insulation and noise reduction test, and a preset volume difference is set.

[0050] Y2. Place various sound insulation devices in sequence under the stamping equipment, start the stamping equipment at the lowest volume, and preset the interval length. After each preset interval length, increase the preset volume corresponding to the stamping equipment. Collect the actual sound insulation data corresponding to the stamping equipment after each volume increase, including the residual volume and transmission coefficient in the factory, until the volume corresponding to the stamping equipment increases to the upper limit volume reference value. Stop the test and summarize the sound insulation data of the stamping equipment after each volume increase under the protection of various sound insulation devices.

[0051] As an optional implementation, the analysis obtains the sound insulation equipment corresponding to the stamping equipment. The specific analysis process is as follows: by calculating the formula: , and then analyze and obtain the sound insulation result value β of the ηth sound insulation device η , η is the number of each sound insulation equipment, η=1,2,……,g, g is any integer greater than 2, a' is the set reference factory residual volume, b' is the set reference transmission coefficient, a η is the residual volume of the ηth sound insulation device in the stamping equipment, b η is the transmission coefficient of the ηth sound insulation device of the stamping equipment.

[0052] Sort the sound insulation result values ​​of each sound insulation device in ascending order, and use the sound insulation result value of the sound insulation device ranked first as the upper limit of the sound insulation and noise reduction of each sound insulation device. At the same time, use the sound insulation device with the first sound insulation result value as the sound insulation and noise reduction device corresponding to the stamping equipment.

[0053] When the noise of the stamping equipment during operation is at the second degree of noise, the upper limit of the sound insulation of the sound insulation equipment corresponding to the stamping equipment is obtained by analysis, which provides an effective sound insulation option for the stamping equipment, realizes effective noise isolation, and protects the health of processing personnel and residents in the surrounding environment.

[0054] It should be noted that the reference in-factory residual volume and reference transmission coefficient are set by professional personnel; the reference in-factory residual volume and reference transmission coefficient are used as reference values ​​to judge the effectiveness of each silencer in eliminating the second-degree noise of the stamping equipment.

[0055] The silencer test module is used to install silencers under the stamping equipment when the noise of the stamping equipment during operation is at the third degree of noise, obtain the silencer data of each silencer installed on the stamping equipment during the test, and analyze the silencer corresponding to the stamping equipment.

[0056] It should be noted that the various silencer devices include resistive silencers, reactive silencers and small hole silencers, etc.

[0057] As an optional implementation method, the noise reduction data of each noise reduction device installed on the stamping equipment during the test is obtained, and the specific acquisition process is as follows: K1. Obtain the noise range of the stamping equipment corresponding to the three-degree noise from the database, and use the highest value of the noise range corresponding to the three-degree noise as the upper limit noise reference value of each noise reduction device in the noise reduction test, and set a preset noise difference.

[0058] K2. Place each silencer device in sequence under the stamping equipment, start the stamping equipment at the lowest noise level, and preset the interval length. After each preset interval length, increase the preset noise corresponding to the stamping equipment. Collect the actual sound pressure peak value corresponding to the stamping equipment after each noise increase. Until the noise corresponding to the stamping equipment increases to the upper limit noise reference value, stop the test, and summarize the sound pressure peak value of the stamping equipment after each noise increase under the protection of each silencer device.

[0059] As an optional implementation method, the analysis obtains the silencer device corresponding to the stamping equipment, and the specific analysis process is as follows: if the degree of elimination of the sound pressure peak of the stamping equipment by each silencer is inconsistent, then according to the noise of each silencer during the elimination test, select the silencer devices that have eliminated the highest noise value in the test, and arrange the sound pressure peak values ​​of each silencer in order from high to low, and use the silencer device that ranks first in the sound pressure peak value during the elimination test as the silencer corresponding to the stamping equipment.

[0060] If all the silencers of the corresponding device of the stamping equipment reach the state of eliminating the sound pressure peaks during the test, compare the noise frequency characteristics eliminated by each silencer with the noise frequency characteristics under the three-degree noise corresponding to the current stamping equipment. If the noise frequency characteristics eliminated by a silencer are the same as the noise frequency characteristics under the three-degree noise corresponding to the current stamping equipment, then the silencer will be used as the silencer corresponding to the stamping equipment, and the silencer corresponding to the stamping equipment can be obtained through analysis.

[0061] When the noise level of the stamping equipment during operation is at the third degree, the corresponding silencer device of the stamping equipment is analyzed to ensure the comfort of the stamping equipment operating environment in the factory, reduce the hearing damage caused by the noise of the stamping equipment operation, and ensure the compliance of the factory stamping equipment operation.

[0062] The database is used to store noise collection data, basic information of each component, vibration intensity, sound insulation information and sound pressure peak value.

[0063] The display terminal is used to display the noise reduction equipment that matches the stamping equipment at each noise generation level.

[0064] The embodiment of the present invention analyzes the collection of noise generation conditions that will appear when the stamping equipment is running, and then performs noise reduction tests at various noise levels based on the noise condition collection, and excludes additional situations where the stamping equipment is damaged before the test, thereby ensuring the uniformity of conditions during the noise reduction test of the stamping equipment, and then analyzing the corresponding noise reduction device selection for the stamping equipment at various levels of noise, thereby achieving effective noise reduction of the stamping equipment, and allowing the stamping equipment to obtain the necessary noise reduction at various noise angles, thereby ensuring the comfort of the stamping equipment operating environment in the factory, reducing hearing damage caused by the stamping equipment operating noise, reducing the noise and noisy impact of the stamping equipment noise on the surrounding environment, and ensuring the legality of the factory stamping equipment operation.

[0065] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
