Abstract
Description
Background Art
[0002] Narrow lap resistance welding machines and laser welding machines include double shears, which are frequently replaced wear parts. After replacing the double shears, it is necessary to measure the shear blade clearance of the double shears to determine whether the double shear accuracy meets the requirements, so as to obtain qualified welds.
[0003] At present, when the shear gap is between the maximum and minimum values, it can be judged that the double shearing precision meets the requirements. Since the fluctuation of the entire shear gap at different positions is not taken into account, when the above judgment method is used for thin and brittle products such as high silicon steel, the strip steel is prone to produce more bad fractures and it is difficult to meet the welding requirements. Therefore, when producing thin and brittle products such as high silicon steel, technicians need to judge whether the double shearing precision meets the requirements according to the weld conditions when the shear gap is between the maximum and minimum values. However, there is a disadvantage of low judgment efficiency. Summary of the invention

[0042] Figure 1 A flow chart showing a method for determining the accuracy of a welding machine shear blade in an embodiment of the present application is shown. Figure 1 , provides a method for determining the accuracy of the shear blade of a welding machine, including at least S1 to S2, which are described in detail as follows:
[0043] In step S1, the shearing gaps of at least five positions of the welding machine shearing blades distributed sequentially in the width direction of the strip are obtained. The shearing gap is the gap when the upper shearing blade and the lower shearing blade of the double shear are in contact.
[0044] In some embodiments, the position corresponding to the shear blade gap is the position corresponding to the bolt hole.
[0045] In step S2, based on the standard deviation and / or range and / or standard deviation rate of the shear blade gap, it is determined whether the shear blade accuracy of the welding machine meets the preset requirements, wherein the preset requirements include a first requirement corresponding to the standard deviation, a second requirement corresponding to the range and a third requirement corresponding to the standard deviation rate.
[0046] In some embodiments, before judging whether the shear blade accuracy of the welding machine meets the preset requirements based on the standard deviation and / or range and / or standard deviation rate of the shear blade gap, it also includes: determining the standard deviation, range and standard deviation rate of the shear blade gap based on the shear blade gap.
[0047] In some embodiments, the standard deviation of the shear gap is determined using the following formula: Where S is the standard deviation, j is the number of the shear gap, N is the total number of shear gaps, and X j is the jth shear gap, is the average value of the shear blade gap.
[0048] In some embodiments, the range of the shear gap is determined using the following formula: R = X max -X min , where R is the range, X max is the maximum value of the shear blade gap, X min is the minimum value of the shear blade clearance.
[0049] In some embodiments, the standard deviation rate of the shear gap is determined using the following formula: Among them, V is the standard deviation rate, S is the standard deviation, is the average value of the shear blade gap.
[0050] In some embodiments, judging whether the shearing blade accuracy of the welding machine meets the preset requirements according to the standard deviation and / or range and / or standard deviation rate of the shearing blade gap includes: judging that the shearing blade accuracy of the welding machine meets the preset requirements when the standard deviation meets the first requirement, the range meets the second requirement, or the standard deviation rate meets the third requirement. Among the three conditions that the standard deviation meets the first requirement, the range meets the second requirement, and the standard deviation rate meets the third requirement, if one of the conditions is met, it can be judged that the shearing blade accuracy of the welding machine meets the preset requirements.
[0051] In some embodiments, judging whether the shear blade accuracy of the welding machine meets the preset requirements according to the standard deviation and / or range and / or standard deviation rate of the shear blade gap includes: judging that the shear blade accuracy of the welding machine meets the preset requirements when the standard deviation meets the first requirement, the range meets the second requirement, and the standard deviation rate meets the third requirement. Among the three conditions that the standard deviation meets the first requirement, the range meets the second requirement, and the standard deviation rate meets the third requirement, if the three conditions are met, it can be judged that the shear blade accuracy of the welding machine meets the preset requirements. When the three conditions are met, the shear blade of the welding machine can continue to be used without adjustment.
[0052] In some embodiments, the preset requirements also include a first target requirement corresponding to continued use after grinding and a second target requirement corresponding to the need to be replaced, and judging whether the accuracy of the welding machine shear blade meets the preset requirements based on the standard deviation and / or range and / or standard deviation rate of the shear blade gap includes: among the three conditions that the standard deviation meets the first requirement, the range meets the second requirement, and the standard deviation rate meets the third requirement, if two of them are met, the first target requirement is met, and if one or none of them are met, the second target requirement is met. When the first target requirement is met, it can be understood that the welding machine shear blade can continue to be used after grinding, and when the second target requirement is met, it can be understood that the welding machine shear blade needs to be replaced.
[0053] In some embodiments, the first requirement includes a first threshold, including: if the standard deviation is less than or equal to the first threshold, the standard deviation meets the first requirement; if the standard deviation is greater than the first threshold, the standard deviation does not meet the first requirement. The first threshold can be an empirical value, can be set according to the size of the welding machine shear blade, or can be a fixed value, such as 0.016.
[0054] In some embodiments, the second requirement includes a second threshold, including: if the range is less than or equal to the second threshold, the range meets the second requirement; if the range is greater than the second threshold, the range does not meet the second requirement. The second threshold can be an empirical value, can be set according to the size of the welding machine shear blade, or can be a fixed value, such as 0.05 mm.
[0055] In some embodiments, the third requirement includes a third threshold, including: if the standard deviation rate is less than or equal to the third threshold, the standard deviation rate meets the third requirement; if the standard deviation rate is greater than the third threshold, the standard deviation rate does not meet the third requirement. The second threshold can be an empirical value, can be set according to the size of the welding machine shear blade, or can be a fixed value, such as 0.03.
[0056] In order to better understand the embodiments of the present application, two examples are provided as follows:
[0057] Example 1: The first threshold is 0.016, the second threshold is 0.05mm, and the third threshold is 0.03. The shear gaps on the inlet side are 0.49mm, 0.51mm, 0.53mm, 0.51mm, 0.51mm, 0.51mm, 0.51mm, 0.50mm, 0.52mm, 0.51mm, 0.51mm, 0.50mm, then the calculated standard deviation is 0.009166, the range is 0.04mm, the average value of the shear gap is 0.51mm, and the standard deviation rate is 0.018001. The standard deviation is less than the first threshold, the range is less than the second threshold, and the standard deviation rate is less than the third threshold. It can be seen that the inlet The shear blade gap accuracy on the side meets the preset requirements; the shear blade gaps on the outlet side are 0.47mm, 0.48mm, 0.47mm, 0.48mm, 0.47mm, 0.47mm, 0.47mm, 0.47mm, 0.47mm, 0.47mm, 0.47mm, 0.47mm, 0.47mm, 0.47mm, 0.46mm, respectively. The calculated standard deviation is 0.004742, the range is 0.02mm, the average value of the shear blade gap is 0.47mm, the standard deviation rate is 0.010073, the standard deviation is less than the first threshold, the range is less than the second threshold, and the standard deviation rate is less than the third threshold. It can be seen that the shear blade gap accuracy on the outlet side meets the preset requirements.
[0058] Example 2: The first threshold is 0.016, the second threshold is 0.05mm, and the third threshold is 0.03. The shear gaps on the inlet side are 0.52mm, 0.52mm, 0.57mm, 0.56mm, 0.56mm, 0.57mm, 0.56mm, 0.57mm, 0.56mm, 0.59mm, 0.6mm, 0.57mm, 0.55mm, respectively. The calculated standard deviation is 0.021784, the range is 0.08mm, the average value of the shear gap is 0.56mm, and the standard deviation rate is 0.038794. The standard deviation is greater than the first threshold, the range is greater than the second threshold, and the standard deviation rate is greater than the third threshold. The shear gap accuracy on the inlet side does not meet the second target requirement and needs to be replaced. ; The shear blade gaps on the outlet side are 0.56mm, 0.56mm, 0.57mm, 0.58mm, 0.57mm, 0.56mm, 0.56mm, 0.57mm, 0.57mm, 0.56mm, 0.55mm, 0.55mm, and 0.55mm respectively. The calculated standard deviation is 0.008904, the range is 0.03mm, the average value of the shear blade gap is 0.56mm, and the standard deviation rate is 0.015836. The standard deviation is less than the first threshold, the range is less than the second threshold, and the standard deviation rate is less than the third threshold. It can be seen that the shear blade gap accuracy on the outlet side meets the preset requirements.
[0059] Figure 2 A block diagram of a device for determining the accuracy of a welding machine cutting blade according to an embodiment of the present application is shown. Figure 2 According to the second aspect of the present application, a welding machine shear blade accuracy judgment device 100 is provided, comprising:
[0060] An acquisition unit 101 acquires the shear blade gaps of at least five positions of the welding machine shear blades distributed sequentially in the width direction of the strip;
[0061] The judgment unit 102 judges whether the shear blade accuracy of the welding machine meets the preset requirements according to the standard deviation and / or range and / or standard deviation rate of the shear blade gap, wherein the preset requirements include a first requirement corresponding to the standard deviation, a second requirement corresponding to the range and a third requirement corresponding to the standard deviation rate.
[0062] In the present application, the shear blade accuracy of the welding machine is judged whether it meets the preset requirements based on the standard deviation or range or standard deviation rate of the shear blade gap. The standard deviation represents the distribution of absolute deviation, the range represents extreme conditions, and the standard deviation rate represents the distribution of standard relative deviation. That is, the standard deviation, range or standard deviation rate can reflect the fluctuation of the shear blade gap, and the shear blade accuracy of the welding machine can be judged without combining the weld conditions. The efficiency of judging the shear blade accuracy of the welding machine is relatively high.
