Description

Technical Field

[0001] This invention relates to the field of parts processing technology, specifically to a method for processing round steel ring fittings. Background Technology

[0002] In existing technologies, projects requiring a large number of steel railings necessitate the provision of numerous round steel ring fittings. Currently, these fittings are typically custom-purchased or cast from specialized factories and then assembled and welded onto the steel railings according to design drawings. This method, by directly purchasing semi-finished steel railing materials such as round steel ring fittings for railing assembly, eliminates the need for secondary manual processing, resulting in high processing efficiency, but also high cost and a long procurement cycle. For projects requiring only a small number of railing rings, with lower costs and shorter construction periods, the time-consuming and costly method of custom-purchasing from specialized factories is no longer suitable. Summary of the Invention

[0003] The present invention aims to solve at least one of the problems mentioned in the background art above, and provides a method for processing round steel ring fittings, which is suitable for processing a small number of round steel ring fittings, and can reduce costs and shorten the construction period.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A method for processing round steel ring fittings includes the following steps:

[0006] S1, The steel bars are bent and rolled into spiral stirrups by a steel bar bending machine, and the horizontal projection of the spiral stirrups is a non-closed circle;

[0007] S2, the spiral stirrup is cut to obtain several steel coil semi-finished products. The steel coil semi-finished products include a body, the body has two spaced-apart butt ends, and the body and the two butt ends are not in the same plane.

[0008] S3, Level the steel coil semi-finished product so that the body and the two mating ends are in the same plane;

[0009] S4. Weld and fix the two butt joints of the leveled steel coil semi-finished product to obtain the finished steel ring accessory.

[0010] Furthermore, in step S3, the semi-finished steel coil is leveled using a leveling device.

[0011] Furthermore, the leveling device includes a base, a support frame, a pressure plate, a jack, and a workpiece placement platform. The support frame is fixed to the base, the pressure plate is fixed to the support frame, the jack is mounted on the base, and the workpiece placement platform is connected to the jack. The workpiece placement platform is located below the pressure plate, and the jack can drive the workpiece placement platform to move closer to the pressure plate, thereby leveling the semi-finished steel coil through the cooperation of the pressure plate and the workpiece placement platform.

[0012] Furthermore, the leveling device also includes several pairs of spaced-apart diagonal braces, each pair of diagonal braces being located on opposite sides of the support frame, one end of each diagonal brace being fixedly connected to the support frame, and the other end of each diagonal brace being anchored to the concrete ground.

[0013] Further, step S3 includes the following steps:

[0014] S31, the workpiece placement platform is lowered to a position away from the pressure plate by means of the jack;

[0015] S32, place the steel coil semi-finished product on the workpiece placement platform, so that the butt joint end of the steel coil semi-finished product is placed on the side facing the operator.

[0016] S33, the workpiece placement platform is moved toward the pressure plate by the jack, so that pressure is applied to the two docking ends by the cooperation of the pressure plate and the workpiece placement platform until the body and the two docking ends are in the same plane;

[0017] S34, the two butt joints of the leveled steel coil semi-finished product are fixedly connected by spot welding;

[0018] S35, the workpiece placement platform is lowered to a position away from the pressure plate by the jack, and the steel coil semi-finished product located on the workpiece placement platform is taken out.

[0019] Furthermore, the rebar bending machine includes a base, a bending assembly, and a guiding assembly. The bending assembly includes a bending shaft rotatably mounted on the base and a bending drive connected to the bending shaft for driving the bending shaft to rotate. The bottom of the bending shaft is provided with a fixing groove for fixing one end of the rebar. The guiding assembly includes a guiding drive mounted on the base and a guide member spaced apart from the bending shaft. The guide member is provided with a guide groove for supporting the rebar. The guiding drive is connected to the guide member to drive the guide member to move axially along the bending shaft.

[0020] Further, step S1 includes the following steps:

[0021] S11, one end of the reinforcing bar is inserted into the space between the guide and the bending shaft, and the reinforcing bar is supported at the guide groove of the guide and one end is inserted into the fixing groove of the bending shaft;

[0022] S12, the bending drive drives the bending shaft to rotate, causing the reinforcing bar to bend and wrap around the bending shaft. At the same time, the guide drive drives the guide to move away from the fixed groove, thereby bending and rolling the reinforcing bar into a spiral stirrup wrapped around the bending shaft.

[0023] Further, in step S4, the two butt joints of the leveled steel coil semi-finished product are fully welded, and the welded area is ground to obtain the finished steel ring accessory.

[0024] Furthermore, in step S2, flame cutting is used to cut the spiral stirrup along the axial direction of the spiral stirrup to obtain multiple steel coil semi-finished products.

[0025] By adopting the above technical solution, the present invention has the following beneficial effects:

[0026] When processing steel railings requires a small quantity of low-cost round steel ring fittings, compared to the traditional method of large-scale steel railing manufacturing which involves one-stop customized procurement of all materials and fittings, resulting in high costs, long cycles, and unpredictable delivery times, the round steel ring fitting processing method of this invention uses self-procured steel bars as raw materials. By employing steps such as rolling, cutting, leveling, and welding the butt joints of the steel bars, finished round steel ring fittings that meet the requirements can be obtained. This method is suitable for processing small quantities of round steel ring fittings for products such as steel railings, reducing costs and shortening the delivery time.

[0027] The processing method for round steel ring fittings of the present invention involves bending and rolling steel bars into spiral stirrups using a steel bar bending machine, and then cutting the spiral stirrups along the axial direction using flame cutting. This allows multiple semi-finished steel coils to be obtained at one time, thus improving the processing efficiency of round steel ring fittings.

[0028] Furthermore, the processing method for round steel ring fittings of the present invention does not require the use of specialized equipment with complex structures, such as spring winding machines used in specialized factories to process round steel ring fittings. The steel bar bending machine and leveling device used are simple in structure and can be obtained or manufactured by ordinary steel processing factories to meet the temporary processing needs of small quantities of round steel ring fittings for products such as steel guardrails.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] Please see Figures 1 to 3 This invention provides a preferred embodiment of a method for processing round steel ring fittings, mainly used for processing small quantities of round steel ring fittings for temporary, low-volume steel guardrails and other products. The method includes the following steps:

[0044] S1, the steel bar 300 is bent and rolled into a spiral stirrup 400 by the steel bar bending machine 100. The horizontal projection of the spiral stirrup 400 is a non-closed circle.

[0045] The reinforcing bar 300 can be made of round steel or other steel materials. In this embodiment, the reinforcing bar bending machine 100 includes a base 10, a bending assembly 30, and a guide assembly 40. The bending assembly 30 includes a bending shaft 31 rotatably mounted on the base 10 and a bending drive component 33 connected to the bending shaft 31 for driving the bending shaft 31 to rotate. Specifically, the bending shaft 31 is vertically arranged, and the bending drive component 33 can be a geared motor or the like mounted on the base 10. The bottom of the bending shaft 31 is provided with a fixing groove 310 for fixing one end of the reinforcing bar 300.

[0046] The guide assembly 40 includes a guide drive 41 mounted on the base 10 and a guide 43 spaced apart from the bending shaft 31. The guide 43 is provided with a guide groove 430 for supporting the reinforcing bar 300. The guide 43 is connected to the guide drive 41 and moves reciprocally along the axial direction of the bending shaft 31 under the drive of the guide drive 41.

[0047] In this embodiment, the guide assembly 40 is a ball screw, the guide member 43 is the screw nut of the ball screw, and the guide groove 430 is an annular groove recessed on the outer circumferential surface of the screw nut and extending circumferentially along the screw nut. The guide drive member 41 includes the screw shaft 411 of the ball screw and a rotary drive member 413 for driving the screw shaft 411 to rotate. The screw shaft 411 is parallel to and spaced apart from the bending shaft 31, and one end is rotatably connected to the machine base 10. The screw shaft 411 is threadedly connected to the screw nut. The rotary drive member 413 can be a geared motor mounted on the machine base 10 and connected to the screw shaft 411.

[0048] In this embodiment, step S1 specifically includes the following steps:

[0049] S11, the front end of the reinforcing bar 300 is inserted into the space between the guide 43 and the bending shaft 31, and the reinforcing bar 300 is supported at the guide groove 430 of the guide 43 and one end is inserted into the fixing groove 310 of the bending shaft 31.

[0050] S12, the bending drive 33 drives the bending shaft 31 to rotate, causing the steel bar 300 to bend and wrap around the bending shaft 31. At the same time, the guide drive 41 drives the guide 43 to move away from the fixed groove 310, thereby making the steel bar 300 evenly and non-overlappingly wrapped around the bending shaft 31, thus forming a spiral stirrup 400 wrapped around the bending shaft 31.

[0051] During the bending and rolling process of the reinforcing bar 300 by the bending shaft 31, the part of the reinforcing bar 300 to be rolled abuts against the guide member 43. The guide member 43 can limit the reinforcing bar 300 to ensure the smooth bending of the reinforcing bar 300. At the same time, during the bending and rolling process of the reinforcing bar 300 by the bending shaft 31, the guide member 43 can move away from the fixed groove 310 under the drive of the guide drive member 41, so as to gradually raise the part of the reinforcing bar 300 to be rolled through the guide groove 430, thereby bending and rolling the reinforcing bar 300 into a spiral stirrup 400 wrapped on the bending shaft 31.

[0052] S2, please refer to the above as well. Figure 4 and Figure 5 The spiral stirrup 400 is cut to obtain several steel coil semi-finished products 500. The steel coil semi-finished product 500 includes a body 510. The body 510 has two spaced-apart docking ends 520, and the body 510 and the two docking ends 520 are not in the same plane.

[0053] In this embodiment, the spiral stirrup 400 is cut along its axial direction using flame cutting to obtain multiple steel coil semi-finished products 500. Specifically, along the axial direction of the spiral stirrup 400... Figure 4 The dashed line shown cuts the spiral stirrup 400. The dashed line is the cutting path of the flame cutting. The cutting path is parallel to the axis of the spiral stirrup 400 and close to the free end of the spiral stirrup 400.

[0054] Because the spiral stirrup 400 is formed by spiral bending, the two mating ends 520 of the body 510 of the cut steel coil semi-finished product 500 are not at the same height, resulting in the body 510 and the two mating ends 520 not being in the same plane. Figure 5 As shown.

[0055] S3, level the semi-finished steel coil 500 so that the body 510 and the two mating ends 520 are in the same plane.

[0056] Please see also Figures 6 to 8 In this embodiment, the steel coil semi-finished product 500 is leveled by a leveling device 600. The leveling device 600 includes a base 610, a support frame 620, a pressure plate 630, a jack 640, and a workpiece placement platform 650. The support frame 620 is fixed to the base 610, the pressure plate 630 is fixed to the support frame 620, the jack 640 is mounted on the base 610, and the workpiece placement platform 650 is connected to the jack 640 and located below the pressure plate 630. The jack 640 can drive the workpiece placement platform 650 to move closer to the pressure plate 630, thereby leveling the steel coil semi-finished product 500 through the cooperation of the pressure plate 630 and the workpiece placement platform 650.

[0057] In this embodiment, the support frame 620 includes two parallel, spaced-apart uprights 621 and a crossbeam 623 fixedly connecting the top ends of the two uprights 621. The bottom ends of both uprights 621 are fixed to the base 610, and the two uprights 621 are located on opposite sides of the jack 640. The crossbeam 623 is located above the jack 640. The top surface of the pressure plate 630 is fixed to the crossbeam 623, and the two uprights 621 are fixedly connected to opposite ends of the pressure plate 630. The bottom surface of the pressure plate 630 is horizontal. In this embodiment, the jack 640 is a hydraulic jack, the structure of which is existing technology and will not be described in detail here for brevity. The center of the bottom surface of the workpiece placement platform 650 is fixed to the lifting rod of the jack 640, and the top surface of the workpiece placement platform 650 is horizontal.

[0058] In this embodiment, the leveling device 600 further includes several pairs of spaced-apart diagonal braces 660. Each pair of diagonal braces 660 is respectively located on opposite sides of the support frame 620. One end of each diagonal brace 660 is fixedly connected to the upright 621 of the support frame 620, and the other end of each diagonal brace 660 is used to anchor to the concrete ground. Specifically, the end of the diagonal brace 660 away from the upright 621 is welded and fixed to embedded parts such as bolts embedded in the concrete ground. By setting the diagonal braces 660, the leveling device 600 can be prevented from overturning during operation.

[0059] In this embodiment, step S3 includes the following steps:

[0060] S31, the workpiece placement platform 650 is lowered to a position away from the pressure plate 630 by jack 640;

[0061] S32, place the steel coil semi-finished product 500 on the workpiece placement platform 650, so that the mating end 520 of the steel coil semi-finished product 500 is placed on the side facing the operator.

[0062] S33, the workpiece placement platform 650 is moved toward the pressure plate 630 by the jack 640, so that pressure is applied to the two mating ends 520 by the cooperation of the pressure plate 630 and the workpiece placement platform 650 until the body 510 and the two mating ends 520 are in the same plane.

[0063] S34, the two butt joints 520 of the leveled steel coil semi-finished product 500 are fixedly connected by spot welding;

[0064] S35, using jack 640 to lower the workpiece placement platform 650 to a position away from the pressure plate 630, and remove the steel coil semi-finished product 500 located on the workpiece placement platform 650.

[0065] In this embodiment, after the body 510 and the two mating ends 520 are leveled to the same plane, the two mating ends 520 are first spot welded and fixed, and then the jack 640 is depressurized and the workpiece placement platform 650 is lowered through the jack 640 to prevent the two mating ends 520 from not being in the same plane due to the action of its own restoring force after the external force is removed.

[0066] S4. Weld and fix the two mating ends 520 of the leveled steel coil semi-finished product 500 to obtain the finished steel ring accessory 700.

[0067] In this embodiment, the two mating ends 520 of the leveled steel coil semi-finished product 500 are fixed by full welding to fill the gap between the two mating ends 520. Then, the full weld area of ​​the two mating ends 520 is ground to make it smooth and flat, thereby obtaining the finished steel ring accessory 700. Figure 9As shown.

[0068] When processing steel railings requires a small quantity of low-cost round steel ring fittings, compared to the traditional method of large-scale steel railing manufacturing which involves one-stop customized procurement of all materials and fittings, resulting in high costs, long cycles, and unpredictable delivery times, the round steel ring fitting processing method of this invention uses self-procured steel bars 300 as raw materials. By rolling, cutting, leveling, and welding the butt joints 520 of the steel bars 300, finished round steel ring fittings that meet the requirements can be obtained. This method is suitable for processing small quantities of round steel ring fittings for products such as steel railings, reducing costs and shortening the delivery time.

[0069] The processing method for round steel ring fittings of the present invention involves bending and rolling steel bars 300 into spiral stirrups 400 using a steel bar bending machine 100, and then cutting the spiral stirrups 400 along the axial direction using flame cutting, thereby obtaining multiple steel coil semi-finished products 500 at one time, which improves the processing efficiency of round steel ring fittings.

[0070] Furthermore, the processing method for round steel ring fittings of the present invention does not require the use of specialized equipment with complex structures, such as spring winding machines used in specialized factories to process round steel ring fittings. The steel bar bending machine 100 and leveling device 600 used are simple in structure and can be obtained or manufactured by ordinary steel processing factories to meet the temporary processing of small quantities of round steel ring fittings for products such as steel guardrails.

[0071] The above description is a detailed description of the preferred embodiments of the present invention.
