Description

Technical Field

[0001] The invention relates to the technical field of round steel straightening, in particular to a round steel straightening process. Background Art

[0002] Round steel is a widely used material in industrial production and construction. However, during the production, transportation and storage of round steel, due to various factors, round steel often bends and deforms, which not only affects the appearance quality of the round steel, but also has an adverse effect on its performance and subsequent processing.

[0003] Traditional round steel straightening processes have some shortcomings. For example, some straightening processes have poor adaptability to the material and size of round steel, and parameters need to be adjusted frequently for round steels of different specifications, which is complicated and inefficient to operate. Some straightening processes can correct the curvature of round steel to a certain extent, but they are easy to damage the surface of round steel during the straightening process, affecting the surface quality of round steel. In addition, traditional straightening processes are often difficult to meet some high-precision application scenarios in terms of straightening accuracy and straightness.

[0004] Therefore, in order to improve the straightening quality and efficiency of round steel and reduce the straightening cost, it is necessary to improve and innovate the traditional round steel straightening process. Summary of the invention

[0005] 1. Technical issues to be resolved In view of the deficiencies in the prior art, the present invention provides a round steel straightening process, which has the advantages of improving the straightening accuracy of round steel, etc., and solves the problem that traditional straightening processes are often difficult to meet some application scenarios with high precision requirements in terms of straightening accuracy and straightness.

[0006] (II) Technical solution To achieve the above object, the present invention provides the following technical solution: A round steel straightening process, comprising the following specific steps: S1 equipment inspection, inspecting the mechanical parts of the straightening machine, such as the straightening rollers, the transmission system, and the supporting structure, to ensure that they are in normal working condition without wear, deformation or damage; S2 round steel pretreatment, clean the surface of the round steel to be straightened, remove oil, rust, oxide scale impurities, so as to avoid these impurities have an adverse effect on the straightening effect; S3 installs the round steel and places it at the feeding end of the straightening machine, ensuring that the center line of the round steel and the center line of the straightening machine are basically coincident to ensure that the round steel is evenly stressed during the straightening process; S4: Initial straightening: Start the straightening machine according to the equipment operating procedures, start the motor of the straightening machine, and make the straightening roller start to rotate; Feed straightening: feed the round steel into the straightening machine at an appropriate speed so that it is gradually straightened under the action of the straightening roller. During the feeding process, closely observe the straightening of the round steel. If any abnormality is found (such as the round steel is stuck, the curvature is still too large after straightening), stop the machine in time to check and adjust the parameters; S5 Intermediate inspection, shutdown After completing the initial straightening, stop the machine and take out the round steel; S6 secondary straightening (if necessary), parameter adjustment: adjust the straightening parameters accordingly according to the results of the intermediate inspection; Straighten again, put the round steel back into the straightening machine and perform secondary straightening according to the adjusted parameters; S7 Post-straightening Processing, Quality Inspection: Re-measure and inspect the round steel after secondary straightening to ensure that its dimensional accuracy and straightness meet the requirements; S8 Surface treatment (if necessary): clean the surface of the straightened round steel again or perform anti-rust treatment to prevent the round steel from rusting during storage and transportation; S9 Packaging and storage: The straightened round steel should be packaged to protect the surface of the round steel from damage. The packaged round steel should be stored in a dry, ventilated and flat place to avoid deformation of the round steel caused by excessive stacking.

[0007] Preferably, S1 checks the electrical system, including the motor, controller, and sensor, to ensure that the electrical connection is good and the equipment is powered normally; Check the hydraulic or pneumatic system (if applicable) to ensure that the pressure is stable and there are no leaks of oil or air.

[0008] Preferably, S2 performs preliminary size measurement and appearance inspection on the round steel, and records the original curvature, diameter, and length parameters of the round steel, so as to subsequently evaluate the straightening effect.

[0009] Preferably, the S3 adjusts the straightening parameters, and adjusts the spacing, pressing amount and straightening speed of the straightening rollers according to the material, diameter and original curvature parameters of the round steel.

[0010] Preferably, in S3, for round steel with higher hardness, the pressing amount of the straightening roller should be appropriately reduced and the straightening speed should be reduced; for round steel with larger diameter, the spacing between the straightening rollers should be appropriately increased.

[0011] Preferably, the S5 measurement and inspection uses measuring tools (such as calipers, micrometers, and rulers) to measure the size and check the curvature of the round steel after straightening, records the measurement results, and determines whether the straightening effect of the round steel meets the expected requirements based on the measurement results. If not, analyze the reasons and adjust the straightening parameters.

[0012] (III) Beneficial effects Compared with the prior art, the present invention provides a round steel straightening process, which has the following beneficial effects: 1. This round steel straightening process can improve the straightening accuracy. By accurately adjusting the straightening parameters and conducting intermediate inspections, secondary straightening and other steps, the straightening accuracy of the round steel can be significantly improved, so that the straightness and dimensional accuracy of the straightened round steel can better meet the high-precision requirements of industrial production and construction fields, and enhance the process adaptability. This improved version of the process can flexibly adjust the straightening parameters according to the material, diameter, original curvature of the round steel, etc., and has stronger adaptability to round steels of different specifications and types, reducing the time and labor costs of frequently adjusting equipment due to changes in specifications.

[0013] 2. The round steel straightening process can protect the surface quality of the round steel. The surface of the round steel is cleaned and pre-treated before straightening, and the pressing amount and straightening speed are reasonably controlled during the straightening process. This can effectively reduce the damage to the surface of the round steel, maintain the good surface quality of the round steel, and improve its subsequent performance and aesthetics.

[0014] 3. The round steel straightening process can effectively improve production efficiency, optimize installation, feeding and straightening processes, as well as reasonable equipment inspection and parameter adjustment, which can reduce failures and pauses in operation, improve the overall production efficiency of round steel straightening, meet the needs of large-scale production, and reduce costs. By improving straightening accuracy, protecting surface quality and improving production efficiency, this improved process can reduce the scrap rate and rework rate of round steel, thereby reducing production costs and improving the economic benefits of the enterprise.
