[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] Please refer to Figure 1 As shown, a noise reduction test system for the security of a stamping equipment includes a stamping equipment operation analysis module, a shock-absorbing equipment test module, a sound insulation equipment test module, a muffler equipment test module, a display terminal, and a database.

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

[0021] A stamping equipment operation analysis module is used to collect noise acquisition data of the stamping equipment at each time period during operation, and analyze to obtain a collection of noise generation conditions of the stamping equipment during operation.

[0022] It should be noted that analyzing the collection of noise generation conditions is to more clearly know which levels of noise will be generated by the stamping equipment during operation, realize a comprehensive analysis and generalization of any noise situations that may occur in the stamping equipment, and comprehensively reduce the noise generated during the operation of the stamping equipment.

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

[0024] As an optional implementation method, the specific analysis process for analyzing and obtaining the collection of noise generation conditions of the stamping equipment during operation is as follows: Use the noise monitoring equipment to monitor the sound volume of the stamping equipment during operation, and obtain the noise acquisition data of the stamping equipment at each time period during operation, including sound pressure level and spectrum, and record them as A t and B t , where t is the number of each time period, t = 1, 2, ……, s, and s is any integer greater than 2.

[0025] If (A t < A') ∧ (B t < B'), the noise presented by the stamping equipment at the t-th time period during operation is recorded as first-degree noise, then it is determined that the noise of the stamping equipment during operation is in the first-degree noise state, and then component monitoring corresponding to the stamping equipment is performed, and a shock and noise reduction test for the first-degree noise of the stamping equipment is carried out. ∧ represents "and", 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 at the t-th time period during operation is recorded as second-degree noise, then it is determined that the noise of the stamping equipment during operation is in the second-degree noise state, and a sound insulation and noise reduction test is carried out for the second-degree noise corresponding to the stamping equipment.

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

[0028] If (A t > A') ∧ (Bt > B'), the noise presented by the stamping equipment during the t-th time period during operation is recorded as third-degree noise. Then, it is determined that the noise of the stamping equipment during operation is in the third-degree noise, and a noise reduction test is carried out for the third-degree noise corresponding to the stamping equipment.

[0029] Statistically analyze the first-degree noise, second-degree noise, and third-degree noise of the stamping equipment during operation corresponding to each time period, and construct a noise generation collection corresponding to the operation of the stamping equipment.

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

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

[0032] As an optional implementation method, perform component monitoring corresponding to the stamping equipment. The specific implementation process is as follows: When the first-degree noise appears during the operation of the stamping equipment, obtain the basic information of each component corresponding to the stamping equipment, including the component wear area and the component gap, and import the basic information of each component corresponding to the stamping equipment into the stamping component state evaluation model: where β p is the basic state value of the p-th component corresponding to the stamping equipment, 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 component wear area of the p-th component corresponding to the pressing equipment, h p is the component gap of the p-th component corresponding to the pressing equipment, 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 component components corresponding to each component of the stamping equipment are normal, which indicates that the noise corresponding to the stamping equipment is emitted under the normal state of the stamping equipment, and then the corresponding noise reduction test is performed. If the basic state value of a certain p-th component corresponding to the stamping equipment is 0, it is determined that the component components corresponding to that component of the stamping equipment are abnormal, which indicates that the noise generated by the stamping equipment is related to the reason of component abnormality. Then, the corresponding component is 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 corresponding to the stamping equipment is obtained by using an industrial endoscope.

[0035] It should be noted that when monitoring the components of a stamping device, in order to understand whether the noise generated by the current stamping device is due to component damage, if so, the components are replaced. If the sound volume during the operation of the stamping device still exceeds the standard after the component replacement, the corresponding noise reduction test is performed; at the same time, monitoring the state of the stamping device is also to ensure the specificity of the noise reduction test of the stamping device, effectively analyze and summarize additional causal factors, and ensure the effectiveness and accuracy of the noise reduction test.

[0036] It should be noted that professional personnel set reference values for component wear, component clearance, and reference component state evaluation; the reference component wear area, reference component clearance, and reference component state evaluation value are used as reference values for determining whether the corresponding components of the stamping device are abnormal.

[0037] By collecting the noise acquisition data of the stamping device at each corresponding time period during operation, analyzing to obtain the collection of the noise generation conditions during the operation of the stamping device, and then realizing a comprehensive test analysis and summary of the noise that the stamping device will generate, so as to ensure effective noise reduction of the stamping device, comprehensively maintain the corresponding environment during factory processing. At the same time, when the stamping device makes noise, the components of the stamping device are detected, so as to understand the component health of the stamping device in real time, efficiently understand the composition of the noise of the stamping device, and collect targeted noise reduction tests.

[0038] The shock absorption equipment test module is used to place various shock absorption devices under the stamping device when the noise during the operation of the stamping device is at the first-degree noise, so as to collect the shock absorption data of the stamping device for testing and placing various shock absorption devices, and analyze to obtain the shock absorption devices for noise reduction corresponding to the stamping device.

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

[0040] As an optional implementation method, the specific process of collecting the shock absorption data of the stamping device for testing and placing various shock absorption devices is as follows: M1. Obtain the amplitude generated by the stamping device at the first-degree noise from the database, and use the amplitude corresponding to the highest sound value of the first-degree noise as the upper limit amplitude reference value for each shock absorption device in the shock absorption and noise reduction test, and set a preset amplitude difference.

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

[0042] As an alternative implementation, the shock-absorbing device corresponding to noise reduction of the stamping equipment obtained through analysis is specifically obtained as follows: If the degrees of reduction in the vibration intensity of the stamping equipment corresponding to each shock-absorbing device are approximately the same, compare the stability values of each shock-absorbing device during noise reduction with the reference stability values stored in the database. If the stability value of a certain shock-absorbing device during noise reduction is greater than or equal to the reference stability value stored in the database, then use this shock-absorbing device as the shock-absorbing device corresponding to noise reduction of the stamping equipment.

[0043] It should be noted that the stability value of each shock-absorbing device during noise reduction: Obtain the vibration intensity reduction values of each shock-absorbing device during the amplitude increase test of the stamping equipment, calculate the average value of each vibration intensity reduction value, and obtain the stability value of each shock-absorbing device during noise reduction.

[0044] If the degrees of reduction in the vibration intensity of the stamping equipment corresponding to each shock-absorbing device are not the same, then select each shock-absorbing device that has been tested to reduce to the highest value of the amplitude, arrange the vibration intensities of each shock-absorbing device in ascending order, and use a certain shock-absorbing device with the first-ranked vibration intensity during the test reduction as the shock-absorbing device corresponding to noise reduction of the stamping equipment.

[0045] When the noise during the corresponding operation of the stamping equipment is at the first-degree noise level, the shock-absorbing device corresponding to noise reduction of the stamping equipment is analyzed to effectively reduce the noise when the stamping equipment has the first-degree noise, and ensure the standardization of the operation of the stamping equipment.

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

[0047] It should be noted that each sound insulation equipment includes a steel plate sound insulation cover, an aluminum alloy sound insulation cover, a fiberglass reinforced plastic sound insulation cover, etc.

[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 value corresponding to the second-degree noise is used as the sound effect test reference value. The preset sound effect difference starts from the minimum value corresponding to the second-degree noise and increases the sound effect in sequence.

[0049] As an alternative implementation, the process of specifically collecting the sound insulation information of each sound insulation equipment of the stamping equipment corresponding to the test device is as follows: Y1. Obtain the volume range of the second-degree noise corresponding to the stamping equipment from the database, use the highest volume corresponding to the second-degree noise as the upper limit volume reference value for each sound insulation equipment in the sound insulation and noise reduction test, and set a preset volume difference.

[0050] Y2. Place each sound insulation device in sequence under the stamping equipment. Start the stamping equipment at the lowest volume and preset an interval duration. After each preset interval duration, increase the preset volume corresponding to the stamping equipment, and collect the actual sound insulation data corresponding to the stamping equipment after each volume increase, including the remaining volume in the factory and the transmission coefficient, until the volume difference corresponding to the stamping equipment increases to the upper limit volume reference value, then stop the test, and summarize the sound insulation data after each volume increase of the stamping equipment under the protection of each sound insulation device.

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

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

[0053] When the noise during the corresponding operation of the stamping equipment is at the second-degree noise, further analyze to obtain the sound insulation upper limit value of the sound insulation device corresponding to the stamping equipment, provide an effective sound insulation option for the stamping equipment, achieve effective noise isolation, and ensure the health of processing personnel and residents in the surrounding environment.

[0054] It should be noted that the reference remaining volume in the factory and the reference transmission coefficient are set by professional personnel; the reference remaining volume in the factory and the reference transmission coefficient are used as reference values for evaluating the elimination intensity of each sound absorption device when eliminating the stamping equipment at the second-degree noise.

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

[0056] It should be noted that each noise elimination equipment includes a resistive muffler, a reactive muffler, a small-hole muffler, etc.

[0057] As an alternative implementation, the process of obtaining the noise reduction data of each noise elimination device corresponding to the stamping equipment is as follows: K1. Obtain the noise range of the three-degree noise corresponding to the stamping equipment 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 for each noise elimination device in the noise reduction test, and set a preset noise difference.

[0058] K2. Place each noise elimination device under the stamping equipment in turn, start the stamping equipment at the lowest noise, and preset an interval duration. After each preset interval duration, increase the preset noise corresponding to the stamping equipment, and 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, then stop the test, and summarize the sound pressure peak values after each noise increase of the stamping equipment under the protection of each noise elimination device.

[0059] As an alternative implementation, the process of analyzing and obtaining the noise elimination device corresponding to the stamping equipment is as follows: If the elimination degrees of the sound pressure peaks of the stamping equipment corresponding to each noise elimination device are inconsistent, then select the noise elimination devices that are tested to the highest noise value according to the noise during the corresponding test elimination of each noise elimination device, arrange the sound pressure peak values of each noise elimination device in descending order, and use a certain noise elimination device with the highest ranking of the sound pressure peak value during the test elimination as the noise elimination device corresponding to the stamping equipment.

[0060] If all the noise elimination devices corresponding to the stamping equipment reach the state where the sound pressure peaks are all eliminated during the test, compare the noise frequency characteristics eliminated by each noise elimination device with the noise frequency characteristics under the three-degree noise corresponding to the current stamping equipment. If the noise frequency characteristics eliminated by a certain noise elimination device are the same as the noise frequency characteristics under the three-degree noise corresponding to the current stamping equipment, then use this noise elimination device as the noise elimination device corresponding to the stamping equipment, and thus analyze and obtain the noise elimination device corresponding to the stamping equipment.

[0061] When the noise during the operation of the stamping equipment is at the three-degree noise, analyze and obtain the noise elimination device corresponding to the stamping equipment, so as to ensure the comfort of the operation environment of the stamping equipment in the factory, reduce the hearing damage caused by the operation noise of the stamping equipment, and ensure the compliance of the operation of the stamping equipment in the factory.

[0062] The database is used to store noise acquisition data, basic information, vibration intensity, sound insulation information, and sound pressure peak values.

[0063] The display terminal is used to display the noise reduction devices corresponding to each noise generation level of the stamping equipment.
