Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of strip steel production, in particular to a strip steel trimming method, device and equipment. BACKGROUND

[0002] The trimming shear is a very key equipment in the cold rolling post-processing line, which is mainly used for cutting off the out-of-tolerance part in the width direction of the strip steel, so that the width of the strip steel reaches the target width to meet the customer's requirements. The trimming shear setting value is issued through three levels, including the trimming mode and the trimming width. However, in the actual production process, part of the raw material coil has been trimmed on the previous production line, but the three-level system issues the trimming data according to the production plan. In this case, the trimming equipment will proceed with the feed cutting according to the setting value issued by the three levels. Since the previous production line has been trimmed, the actual width of the raw material coil is close to the feed position, which is easy to cause the strip steel to scratch the cutter head and cause the cutter head to be damaged, or the cutter head to scratch the strip steel and cause the production line to stop. When the actual strip steel is not trimmed according to the plan on the previous production line, and needs to be trimmed on the current production line, since the three-level system does not issue the trimming, the final product is not trimmed according to the requirements. SUMMARY

[0003] The embodiments of the present application provide a strip steel trimming method, device and equipment, which can at least to some extent solve the problem that the actual trimmed product of the strip steel does not meet the requirements of the order strip steel coil, resulting in that the finished product coil is not trimmed according to the requirements, the trimming shear blade is damaged, and even the production line is stopped.

[0045] According to one aspect of the embodiments of the present application, a strip steel trimming method is provided, referring to Figure 1 The flowchart of the strip steel trimming method is shown, and the method comprises: Figure 1 The flowchart of the strip steel trimming method is shown, and the method comprises:

[0046] S1, obtaining the width of the raw strip steel coil as a compared width parameter,

[0047] S2, obtaining the minimum value of the width of the order strip steel coil as a comparison width parameter;

[0048] S3, determining the trimming mode according to the difference between the compared width parameter and the comparison width parameter;

[0049] S4, trimming the raw strip steel coil based on the trimming mode.

[0050] The beneficial effects of the present application are: by obtaining the width of the raw strip steel coil and the width range of the order strip steel coil required by the customer, different trimming modes are set according to the different ranges required by the customer, so as to prevent errors in trimming during the process of changing the raw strip steel coil into a finished product coil, improve the trimming quality, and reduce defective products.

[0051] In some embodiments of the present application, the determining the trimming mode according to the compared width parameter and the difference between the compared width parameter and the comparison width parameter comprises:

[0052] According to the compared width parameter and the comparison width parameter, if the difference between the compared width parameter and the comparison width parameter is less than a first set difference value, the pre-set trimming mode is called the first trimming mode, wherein the first trimming mode is no trimming;

[0053] If the difference between the compared width parameter and the comparison width parameter is greater than the first set difference value, the pre-set trimming mode is called the second trimming mode, wherein the second trimming mode is trimming.

[0054] It should be understood that by determining different trimming modes, i.e. trimming or no trimming, according to whether the difference between the minimum width of the order steel coil and the width of the raw material steel coil reaches the pre-set first set difference value, here the first set difference value is 15 mm, 15 mm of reserved space is left for the order steel coil to prevent it from being too narrow in the process of being trimmed off, so as to have no tolerance space, thereby improving the yield.

[0055] In some embodiments of the present application, if the difference between the compared width parameter and the comparison width parameter is greater than the first set difference value, the pre-set trimming mode is called the second trimming mode, wherein the second trimming mode is trimming, comprising:

[0056] Obtaining the minimum width of the order steel coil and the maximum width of the order steel coil;

[0057] Determining the trimming width according to the minimum width of the order steel coil and the maximum width of the order steel coil.

[0058] It should be understood that by determining the trimming width value according to the minimum width of the order steel coil and the maximum width of the order steel coil, trimming error caused by the inaccuracy of the trimming set value and the actual value can be prevented, thereby ensuring the accuracy of the trimming of the production line and the stability of the operation of the production line.

[0059] In some embodiments of the present application, according to the minimum width of the order steel coil and the maximum width of the order steel coil, the determining the trimming width comprises:

[0060] According to the minimum width of the order steel coil and the maximum width of the order steel coil, if the difference between the minimum width of the order steel coil and the maximum width of the order steel coil is less than or equal to a second set difference value, the trimming width is determined to be the minimum width of the order steel coil plus 1 mm;

[0061] According to the order strip coil width minimum value and the order strip coil width maximum value, if a difference between the order strip coil width minimum value and the order strip coil width maximum value is greater than a second set difference value, enter a trimming width optimization mode.

[0062] It should be understood that, according to whether the difference between the order strip coil width minimum value and the width maximum value is greater than the second set difference value, if it is less than the order strip coil width minimum value plus 1 mm, the order strip coil can reach the optimal trimming range at high requirements. If it is greater, further subdivide the trimming width, so that the order strip coil can be trimmed according to other indicators at low requirements, so that the production of the punched strip coil is of higher quality.

[0063] In some embodiments of the present application, the order strip coil width minimum value and the order strip coil width maximum value are entered into the trimming width optimization mode, including:

[0064] Obtain the order strip coil thickness;

[0065] If the order strip coil thickness is greater than 0.8 mm and the surface smoothness level is a preset second level, third level or fourth level, the trimming width is determined to be the order strip coil width maximum value minus 1.4 to 1.6 mm. It should be noted that the best value is 1.5 mm.

[0066] If the order strip coil surface level is a preset second level, third level or fourth level, the trimming width is determined to be the order strip coil width maximum value minus 1.9 to 2.1 mm. It should be noted that the best value is 2 mm.

[0067] It should be understood that in the process of cutting the strip, the thinner it is, the more difficult it is to cut. Therefore, when the order strip coil thickness is less than 0.8 mm, a second cutting based on the order strip coil width maximum value minus 2 mm is required to achieve the best cutting yield.

[0068] In some embodiments of the present application, the first set difference value is 15 mm.

[0069] It should be understood that the first set difference value can also be selected as other values in different cutting scenarios.

[0070] In some embodiments of the present application, the second set difference value is 3 mm.

[0071] It should be understood that the second set difference value can also be selected as other values in different cutting scenarios.

[0072] In some embodiments of the present application, when the raw strip coil width value is 0 mm and the trimming width value is no trimming.

[0073] It should be understood that, in order to avoid the abnormality of the trimming width value caused by the lack of the maximum and minimum width values of the raw strip coil data (the export value is 0), a correction program is added, and when the export value is abnormal, the cutting width is no trimming, so that the entire trimming process has better fault tolerance.
