It can lead out branch pipes so that the fluid can flow from the main pipe to the branch pipe. It is widely used in pipeline projects in many industrial fields such as petroleum, chemical industry, and electric power.

[0003] Chinese patent publication number: CN114986099A, discloses a manufacturing method for an inclined branch pipe platform, including: S1: cutting with a band saw and rounding the corners to form a blank; S2: heating the blank to 150℃~200℃, spraying glass lubricant, and after drying, placing it in an electric furnace and heating it to 950℃~970℃ and keeping it warm for 50min~60min; S3: using a local upsetting method to form an intermediate blank, and then using a local forming method to form a formed blank; S4: coloring inspection The surface quality of the formed blank is improved by grinding or machining to remove surface defects such as surface folds and cracks; S5: heat the formed blank to 150℃~200℃, spray glass lubricant, and place it in an electric furnace to heat to 950℃~970℃ after it is dried; S6: extrude the formed blank in the mold to form a middle hole and a flange-like base, and cut the edges while hot to form an inclined branch pipe platform; S7: anneal the inclined branch pipe platform and perform vacuum dehydrogenation treatment to recrystallize the internal structure of the material, eliminate internal stress, and reduce the hydrogen content on the surface of the forging.

[0004] It can be seen that the above technical solution has the advantages of improving material utilization and reducing production costs, but there are still the following problems: during the heating process, uneven heating or improper temperature control at different processing stages may cause uneven deformation of the material during the forming process, thereby affecting the miter angle. In addition, during the local upsetting and local forming process, if the operation is improper, the shape of the blank will also deviate, ultimately affecting the accuracy of the miter angle.

[0016] Furthermore, the structural complexity coefficient is determined according to the structural features of the molding die and the corresponding feature weights.

[0017] Furthermore, the miter angle is compared with a target miter angle, and a method for adjusting the placement angle is determined according to the comparison result, wherein:

[0018] If the miter angle is smaller than the target miter angle, an angle deviation is determined according to the miter angle and the target miter angle, and an adjustment direction of the placement angle is determined according to the angle deviation.

[0019] Further, if the cross-sectional tube wall thickness of a single position is greater than the target thickness, the single position is the target position; if the cross-sectional tube wall thickness of a single position is less than the target thickness, the single position is not the target position.

[0020] Further, the machining allowance position is determined according to the target position and the thickness difference between the cross-section tube wall thickness and the target thickness, wherein:

[0021] Determining a thickness separation threshold according to the thickness difference corresponding to the target position;

[0022] The machining allowance position is determined according to the comparison result between the thickness difference and the thickness separation threshold, wherein:

[0023] If the thickness difference corresponding to a single target position is greater than the thickness separation threshold, the target position is the machining allowance position.

[0040] See also Figure 1 As shown, it is a flow chart of a method for processing an embedded mitered pipe support platform according to an embodiment of the present invention. Specifically, the present invention provides a method for processing an embedded mitered pipe support platform, comprising:

[0041] Step S1, cutting and decontamination pretreatment of the steel tube blank to obtain a first steel tube blank and a second steel tube blank;

[0042] Step S2, heating the first steel tube blank and the second steel tube blank based on a preset heating temperature, and placing the first steel tube blank and the second steel tube blank into a forming mold for diameter expansion forming, wherein:

[0043] During the expansion forming process, the original wall thickness and the expanded wall thickness after a single hydraulic pressure are determined based on a number of measuring points; the wall thickness uniformity of the expanded part is determined based on the original wall thickness and the expanded wall thickness, and the adjustment method of the hydraulic pressure and the hydraulic speed is determined based on the comparison result between the preset range and the wall thickness uniformity;

[0044] Step S3, welding the first steel tube blank and the second steel tube blank, and using a stamping die to stamp the second steel tube blank, wherein:

[0045] After each stamping, the bevel angle of the outer surface of the second steel tube blank is determined, and the adjustment method of the placement angle of the second steel tube blank is determined according to the bevel angle. The machining allowance position is determined according to the comparison result of the cross-sectional wall thickness at several positions of the second steel tube blank and the target thickness, and the adjustment method of the placement position of the second steel tube blank and the cutting method of the second steel tube blank are determined according to the machining allowance position.

[0046] It is understandable that the uniformity of wall thickness is directly related to the quality and performance of the product after forming. Uneven wall thickness may lead to local stress concentration and reduce the strength and pressure resistance of the product. Therefore, during the expansion process, the original wall thickness and the expanded wall thickness are measured based on several measuring points to determine the uniformity of the wall thickness. The hydraulic pressure and hydraulic speed are adjusted according to the comparison results of the wall thickness uniformity and the preset range. Excessive hydraulic pressure or too fast hydraulic speed may cause local rapid deformation of the steel pipe blank and thin the wall thickness. Adjusting the hydraulic pressure and hydraulic speed can make the deformation process more gentle and uniform.

[0047] It is understandable that welding the first steel pipe blank and the second steel pipe blank to form the main structure of the mitered branch pipe platform facilitates the stamping die to stamp the second steel pipe blank to obtain the mitered angle. During the stamping process, the mitered angle is determined in real time, and the placement angle of the second steel pipe blank is adjusted according to the mitered angle to ensure that the final stamped mitered angle meets the requirements. At the same time, under the premise of ensuring the strength and dimensional accuracy of the branch pipe platform, the placement position of the steel pipe blank is determined according to the machining allowance position, and the cutting position is determined to better enable the mitered branch pipe platform to achieve the designed wall thickness and external dimensions.

[0048] In a specific embodiment, the preset heating temperature has a value range of 800°C to 950°C, preferably, the preset heating temperature has a value of 900°C. Several measuring points are the upper, lower, left, and right positions of the middle section of the tube inside and the openings at both ends of the first steel tube blank or the second steel tube blank, the value of the preset range is ±5%, the value range of the target thickness is 0.8cm to 1cm, preferably, the value of the target thickness is 0.9cm, and several positions are the upper, lower, left, and right positions of the middle section of the tube inside and the openings at both ends of the second steel tube blank. In implementation, the preset heating temperature, preset range, several measuring point positions, and the value range and preferred value of the target thickness are not specifically limited here, as long as the steel tube at the preset heating temperature can reach the best plastic state and facilitate the expansion and forming, the target thickness can also be determined according to the processing requirements, and the measuring point position can be determined according to the size of the processed material, which will not be repeated here.

[0049] The present invention monitors the wall thickness at several measuring points to adjust the hydraulic parameters, thereby completing the control of the wall thickness uniformity during the expansion process, effectively avoiding the stress concentration problem caused by uneven wall thickness, and improving the strength and pressure resistance of the branch pipe. At the same time, the miter angle of stamping and the position of the machining allowance are accurately controlled to ensure the dimensional accuracy of the branch pipe, thereby further ensuring that the entire processing process has a good feedback control mechanism to avoid wasting production costs.

[0050] Specifically, the wall thickness difference at a single measuring point is determined according to the original wall thickness and the expanded wall thickness, and the wall thickness uniformity of the expanded portion is determined according to the wall thickness difference.

[0051] Specifically, determine how to adjust the hydraulic pressure and hydraulic speed, including:

[0052] If the wall thickness uniformity exceeds the preset range, the hydraulic pressure is reduced or the hydraulic speed is reduced.

[0053] It is understandable that the wall thickness difference at a single measuring point is the difference between the original wall thickness and the expanded wall thickness, and the wall thickness uniformity of the entire steel tube blank is determined by the wall thickness difference at several measuring points. If the wall thickness uniformity exceeds the preset range, it means that the deformation unevenness of the steel tube blank during the expansion process exceeds the acceptable limit. At this time, the expansion force applied to the steel tube blank is reduced by reducing the hydraulic pressure and hydraulic speed, thereby reducing the uneven wall thickness caused by local rapid deformation.

[0054] In a specific embodiment, the wall thickness uniformity is the standard deviation or range of the wall thickness difference corresponding to a number of measurement points. The larger the standard deviation or range, the worse the wall thickness uniformity. In implementation, the method for confirming the wall thickness uniformity can be determined according to actual conditions, which is not specifically limited here and will not be repeated.

[0055] The present invention accurately monitors the uniformity of wall thickness, adjusts the hydraulic pressure and hydraulic speed based on the feedback of the wall thickness uniformity, controls the wall thickness uniformity in the expansion process within a reasonable range, makes the production process more stable and reliable, ensures the dimensional accuracy of the branch platform, and further ensures that the entire processing process has a good feedback control mechanism to avoid wasting production costs.

[0056] See also Figure 2 As shown, it is a flow chart for determining the reduction ratio in an embodiment of the present invention. Specifically, the comprehensive influence of hydraulic pressure and hydraulic speed on wall thickness uniformity is determined based on the uniform deviation value of wall thickness uniformity and the preset range, the characteristic coefficient and the structural complexity coefficient, and the reduction ratio is determined based on the comprehensive influence degree and the preset influence degree range.

[0057] Specifically, the structural complexity coefficient is determined according to the structural features of the molding die and the corresponding feature weights.

[0058] It can be understood that the uniform deviation value is the difference between the wall thickness uniformity and the preset range, and the characteristic coefficient is the characteristic coefficient of the steel pipe material. Different steel pipe materials deform differently when subjected to hydraulic expansion. Under the same hydraulic pressure and speed, the high-strength steel pipe blank and the low-strength steel pipe blank are more difficult to deform, and the material has poor flow characteristics. The structural complexity coefficient is the complexity coefficient of processing the steel pipe blank into the product shape. The complex structure will cause the steel pipe to be subject to different degrees of restrictions when deforming. Therefore, the comprehensive influence of hydraulic pressure and hydraulic speed on wall thickness uniformity is determined by combining the uniform deviation value, characteristic coefficient and structural complexity coefficient.

[0059] In a specific embodiment, the comprehensive influence degree is the product of the uniform deviation value, the characteristic coefficient and the structural complexity coefficient. The structural features of the molding die include bending, verticality and holes. Since the bending structure is relatively complex, the corresponding weight of the bending structure feature is 0.5, and the remaining weights are 0.25 and 0.25. The calculation formula of the structural complexity coefficient is the sum of the product of the weight of each structural feature and the number of corresponding structural features and the ratio of the number of structural features. The preset influence degree range is 5% to 10%. The preset influence degree range is divided into two intervals, a low influence interval and a high influence interval. When the comprehensive influence degree is in the low influence interval, the reduction ratio range is 4% to 8%, preferably, the reduction ratio is 5%. When the comprehensive influence degree is in the high influence interval, the reduction ratio is 9% to 13%, preferably, the reduction ratio is 10%. In implementation, the value range and preferred value of the comprehensive influence degree can be determined according to actual conditions, and no specific limitation is made here, and no further description is given.

[0060] The present invention determines the comprehensive influence of hydraulic pressure and hydraulic speed on wall thickness uniformity according to the uniform deviation value of wall thickness uniformity and the preset range, the characteristic coefficient and the structural complexity coefficient, and determines the reduction ratio according to the classification of the comprehensive influence degree, which can more accurately control the expansion process and ensure the dimensional accuracy of the branch platform, thereby further ensuring that the entire processing process has a good feedback control mechanism to avoid wasting production costs.

[0061] See also Figure 3 As shown, it is a flow chart of determining the adjustment method of the placement angle according to an embodiment of the present invention. Specifically, the miter angle and the target miter angle are compared, and the adjustment method of the placement angle is determined according to the comparison result, wherein:

[0062] If the miter angle is smaller than the target miter angle, an angle deviation is determined according to the miter angle and the target miter angle, and an adjustment direction of the placement angle is determined according to the angle deviation.

[0063] In a specific embodiment, the bevel angle is determined by measuring the outer surface angle of the first steel tube blank and the second steel tube blank. The preferred value of the target bevel angle is 45°. If the bevel angle is less than the target bevel angle, the angle deviation is the difference between the bevel angle and the target bevel angle. If the target bevel angle is greater than the bevel angle, it means that the angle deviation is positive. Assuming that the bevel angle of the steel tube blank is right bevel, the steel tube blank is placed to the left, or rotated to the left by 2° to 5°, so as to be corrected in the subsequent processing process so that the bevel angle is close to the target bevel angle. In implementation, the adjustment method of the placement angle and the placement position can be determined according to the actual situation, which is not specifically limited here and will not be repeated.

[0064] The present invention monitors the miter angle and compares it with the target miter angle, and adjusts the placement angle and placement position of the steel pipe blank based on the angle deviation, so as to effectively correct the angle error generated in the stamping process, thereby further ensuring that the miter angle meets the design requirements and ensures the dimensional accuracy of the branch platform, thereby further ensuring that the entire processing process has a good feedback control mechanism to avoid wasting production costs.

[0065] Specifically, if the cross-sectional tube wall thickness at a single location is greater than the target thickness, the single location is the target location; if the cross-sectional tube wall thickness at a single location is less than the target thickness, the single location is not the target location.

[0066] See also Figure 4 As shown, it is a flow chart of determining the machining allowance position according to an embodiment of the present invention; specifically, the machining allowance position is determined according to the target position and the thickness difference between the cross-section tube wall thickness and the target thickness, wherein:

[0067] Determining a thickness separation threshold according to the thickness difference corresponding to the target position;

[0068] The machining allowance position is determined according to the comparison result between the thickness difference and the thickness separation threshold, wherein:

[0069] If the thickness difference corresponding to a single target position is greater than the thickness separation threshold, the target position is the machining allowance position.

[0070] It can be understood that, assuming that the cross-sectional tube wall thickness at a single position is greater than the target thickness, it means that the steel tube blank at that position is thicker and there is excess material that can be conveniently processed in subsequent processing. In this case, it is determined as the target position, and a machining allowance position is selected from several target positions. First, the thickness separation threshold is determined as the judgment criterion, the amount of excess material is determined according to the thickness separation threshold, and the corresponding target position is determined as the machining allowance position.

[0071] In a specific embodiment, the thickness difference is the difference between the cross-sectional tube wall thickness and the target thickness, and the thickness separation threshold is the median or mean of several thickness differences. In implementation, the value range and preferred value of the thickness separation threshold can be determined according to actual conditions, and no specific limitation is made here and no further explanation is given.

[0072] The thickness analysis and machining allowance position of the present invention accurately control the wall thickness of the steel pipe. Under the premise of ensuring product strength and performance requirements, excess material is removed to make the wall thickness more uniform, avoid stress concentration problems caused by uneven wall thickness, and further ensure the dimensional accuracy of the branch platform, thereby further ensuring that the entire processing process has a good feedback control mechanism to avoid wasting production costs.

[0073] Specifically, the adjustment direction of the placement position is determined according to the machining allowance position, and the placement position of the second steel tube blank is adjusted according to the adjustment direction.

[0074] In a specific embodiment, if the machining allowance is located at the lower left of the second steel tube blank relative to the stamping die, the second steel tube blank needs to be tilted slightly to the upper left so that the cross-sectional wall thickness of the product is uniform when the stamping die is stamped.

[0075] Specifically, a cutting path is determined according to the machining allowance position and shape information corresponding to the machining allowance position, and the second steel pipe blank is cut according to the cutting path.

[0076] In a specific embodiment, an analysis and cutting system can be added to the processing control system, and the CAD / CAM technology is used to draw the shape corresponding to the machining allowance position in the computer-aided design software, and then the cutting path of the cutting device is generated through the CAM module, and the cutting head is controlled to cut along the cutting path. In implementation, the cutting method of the second steel pipe blank can be determined according to the actual situation, which is not specifically limited here and will not be repeated.

[0077] The present invention accurately adjusts the placement position and the inclination direction of the second steel pipe blank according to the machining allowance position, generates a cutting path, and cuts the machining allowance position of the second steel pipe blank according to the cutting path to ensure the dimensional accuracy of the branch pipe platform, thereby further ensuring that the entire processing process has a good feedback control mechanism to avoid wasting production costs.

However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will fall within the protection scope of the present invention.
