Description

Technical Field

[0001] The present invention relates to the fields of steel structure manufacturing and construction, and particularly to a steel column shaping machine device and a shaping method thereof. Background Art

[0002] In the fields of steel structure manufacturing and construction, as an important load-bearing member, the straightness and shape accuracy of steel columns directly affect the stability and safety of the overall structure. However, steel columns are prone to plastic deformations such as bending and twisting during transportation, storage, or processing. Traditional manual correction methods are inefficient and difficult to guarantee accuracy, while existing mechanical shaping equipment often has problems such as inaccurate positioning, difficult demolding, and low automation. Especially when dealing with steel columns of different specifications, conventional equipment is difficult to achieve adaptive clamping and stable support, resulting in unsatisfactory shaping effects. In addition, problems such as inconvenient removal of the shaped workpiece and low discharging efficiency also restrict production efficiency.

[0003] Therefore, in view of the above problems, a steel column shaping machine device and a shaping method thereof are now developed. Summary of the Invention

[0004] In order to overcome the shortcomings of existing devices, the present invention provides a steel column shaping machine device and a shaping method thereof.

[0005] The technical solution of the present invention is as follows: A steel column shaping machine device includes an installation table. A driving motor is arranged on the left part of the installation table. Four conveying rollers are rotatably arranged on the left part of the installation table. The output shaft of the driving motor is connected to the rightmost conveying roller. A placing table is installed on the front side of the left part of the installation table, and the placing table is connected to the driving motor. A multi-stage hydraulic cylinder is installed on the upper side of the right part of the installation table. A shaping member is connected to the telescopic end of the multi-stage hydraulic cylinder. A pressing mechanism is arranged in the middle of the installation table, and the pressing mechanism is used for pressing and limiting a steel column to be shaped. A demolding mechanism is arranged on the installation table, and the demolding mechanism is used for quickly separating the shaping member from the steel column, facilitating the operator to take out the shaped steel column.

[0006] As an improvement of the above solution, the pressing mechanism includes fixing frames. Three fixing frames are installed on the upper side of the middle of the installation table. Single-stage hydraulic cylinders are installed on the fixing frames, and pressing members are arranged on the telescopic ends of the single-stage hydraulic cylinders.

[0007] As an improvement of the above solution, the demolding mechanism includes a lifting frame. The lifting frame is slidably arranged inside the middle part of the installation table. Two symmetrically arranged guide columns are installed in the middle part of the installation table. The guide columns are slidably connected to the lifting frame. Two first springs are connected between the guide columns and the lifting frame. On the upper sides of the left and right parts of the installation table, two symmetrically arranged mounting plates are bolted respectively. A sliding frame is slidably connected to each mounting plate. The sliding frame can limit the lifting frame. Sliding rods are connected to both the front and rear sides of the pressing member. The sliding rods are in contact with the adjacent sliding frames respectively. A second spring is connected between the sliding frame and the adjacent mounting plate.

[0008] As an improvement of the above solution, a supporting mechanism is further included. The supporting mechanism includes a supporting bracket. Three supporting brackets are slidably arranged on the fixed frame respectively. The supporting brackets are used for supporting the steel column. Fixed rings are installed on both the front and rear parts of the fixed frame. Third springs are connected between the fixed rings and the supporting brackets respectively. The third springs are sleeved on the fixed frame. A friction member is arranged in the middle of the supporting bracket. The friction member is used for enhancing the friction force of the steel column to avoid shaking or displacement during processing.

[0009] As an improvement of the above solution, a discharging mechanism is further included. The discharging mechanism includes an installation frame. The installation frame is installed between the two left fixed frames. A rotating roller is rotatably connected to the installation frame. A connecting shaft is installed on the rotating roller. A pulley assembly is connected between the connecting shaft and the rightmost conveying roller. The pulley assembly is used for transmitting power.

[0010] As an improvement of the above solution, a guiding mechanism is further included. The guiding mechanism includes guiding plates. Two symmetrically arranged guiding plates are arranged on the upper side of the left part of the installation table. The guiding plates are used for guiding the feeding of the steel column. Two limiting plates are installed on the top of the installation table. The limiting plates are used for guiding the limiting of the steel column.

[0011] As an improvement of the above solution, an adapting plate is further included. The adapting plates are connected to the left sides of the supporting brackets respectively. The adapting plates are used for guiding the height difference of the steel column to avoid hard friction between the steel column and the supporting brackets.

[0012] As an improvement of the above solution, the inner sides of the pressing members are all arc-shaped structures for pressing the steel column.

[0013] As an improvement of the above solution, a blocking plate is arranged on the left part of the lifting frame, and a notch plate is arranged on the right side. Both the notch plate and the blocking plate are used for blocking the steel column.

[0014] A shaping use method of a steel column shaping machine device is as follows: The specific steps are as follows: Step 1: Place the steel column to be shaped on the conveying rollers at the left part of the installation table. The guiding plate and the limiting plate guide it to be centered and positioned. Start the driving motor, and convey the steel column to the shaping station to the right through the conveying rollers; Step 2: The single-stage hydraulic cylinder of the pressing mechanism pushes the arc-shaped pressing piece downward, so that the lifting frame drives the blocking plate and the notch plate to move. After the steel column contacts the blocking plate of the lifting frame, the notch plate limits its position and makes it dock at the shaping position. The supporting bracket synchronously jacks up the friction piece to complete the two-way fixation; Step 3: The multi-stage hydraulic cylinder drives the shaping piece to move, applies force to correct the deformed part of the steel column. During the process, the third spring of the supporting mechanism adaptively adjusts the lifting force to ensure stability; Step 4: After the shaping is completed, the hydraulic cylinder retracts to drive the shaping piece to reset. The sliding frame of the demolding mechanism resets to assist in separation. The driving motor rotates in reverse, and drives the rotating roller through the pulley assembly to send the steel column to the left out to the conveying rollers to complete the discharging; Step 5: Each mechanism resets to the initial state to prepare for the next operation.

[0015] By adopting the above technical solutions, the advantages of the present invention are as follows: 1. Through the coordinated action of the arc-shaped pressing piece of the pressing mechanism and the friction piece of the supporting mechanism, the present invention realizes the two-way fixation of the steel column up and down, avoids offset or vibration during the shaping process, can quickly separate the shaping piece from the workpiece after processing, reduces the risk of adhesion, significantly improves the straightness and shape accuracy after shaping, and meets the high-standard engineering requirements.

[0016] 2. The present invention forms a coherent automatic conveying system through the conveying rollers, the discharging mechanism and the pulley assembly, realizes the automatic feeding and discharging of the steel column, reduces manual intervention. The shaping piece driven by the multi-stage hydraulic cylinder cooperates with the synchronous action of the pressing mechanism, and can quickly complete the correction operation.

Detailed implementation manners

[0026] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrative purposes only and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually those in conventional experiments. Embodiment 1

[0027] A steel column shaping machine device, as Figures 1-8 shown, includes a mounting table 1. A driving motor 2 is arranged on the left part of the mounting table 1. Four conveying rollers 3 are rotatably arranged on the left part of the mounting table 1. The output shaft of the driving motor 2 is connected to the rightmost conveying roller 3. A placing table 4 is installed on the front side of the left part of the mounting table 1. The placing table 4 is connected to the driving motor 2. A multi-stage hydraulic cylinder 5 is installed on the upper side of the right part of the mounting table 1. A shaping part 6 is connected to the telescopic end of the multi-stage hydraulic cylinder 5. A pressing mechanism 7 is arranged in the middle of the mounting table 1. The pressing mechanism 7 is used to press and limit the steel column to be shaped. A demolding mechanism 8 is arranged on the mounting table 1. The demolding mechanism 8 is used to quickly separate the shaping part 6 from the steel column, facilitating the operator to take out the shaped steel column.

[0028] It should be noted that when the steel column shaping machine device is working, the operator first places the steel column to be shaped on the conveying roller 3 at the left part of the installation table 1, starts the driving motor 2, drives the rightmost conveying roller 3 to rotate through the output shaft, and then drives the rest of the conveying rollers 3 to rotate synchronously, so that the steel column is smoothly conveyed to the lower part of the pressing mechanism 7. Then the pressing mechanism 7 acts to firmly press the steel column on the installation table 1 to ensure that there is no deviation during the shaping process. Subsequently, the multi-stage hydraulic cylinder 5 at the right part of the installation table 1 starts to push the shaping part 6 downward to apply pressure to the deformed part of the steel column, so that it gradually returns to the standard shape. After the shaping is completed, the demoulding mechanism 8 acts to quickly separate the shaping part 6 from the steel column to avoid difficulty in taking out due to metal adhesion. Finally, the pressing mechanism 7 resets, and the operator can easily remove the shaped steel column.

[0029] The pressing mechanism 7 includes a fixed frame 71. Three fixed frames 71 are installed on the upper side of the middle part of the installation table 1. Single-stage hydraulic cylinders 72 are installed on the fixed frames 71. Pressing parts 73 are arranged on the telescopic ends of the single-stage hydraulic cylinders 72. The inner sides of the pressing parts 73 are all arc-shaped structures for pressing the steel column.

[0030] It should be noted that when the steel column shaping machine is working, the operator first places the steel column to be shaped on the left conveying roller 3, starts the driving motor 2, and conveys the steel column to the lower part of the pressing mechanism 7 by driving the four conveying rollers 3 in linkage. At this time, the single-stage hydraulic cylinders 72 on the three fixed frames 71 in the middle of the installation table 1 act synchronously to push the arc-shaped pressing parts 73 at their telescopic ends downward to uniformly press the steel column from above and the side. The arc-shaped structure of the pressing part 73 fits the outer wall of the steel column to ensure uniform distribution of the pressing force, avoid local deformation, and prevent the steel column from shifting or shaking during the shaping process.

[0031] The demoulding mechanism 8 includes a lifting frame 81. The lifting frame 81 is slidably arranged inside the middle part of the installation table 1. A blocking plate is arranged on the left part of the lifting frame 81, and a notch plate is arranged on the right side. Both the notch plate and the blocking plate are used to block the steel column. Two symmetrically arranged guide columns 83 are installed in the middle of the installation table 1. The guide columns 83 are slidably connected to the lifting frame 81. Two first springs 82 are connected between the lifting frame 81 and the guide columns 83. Two symmetrically arranged mounting plates 84 are bolted to the upper sides of the left and right parts of the installation table 1. Sliding frames 86 are slidably connected to the mounting plates 84. The sliding frames 86 can limit the lifting frame 81. Sliding rods 87 are connected to the front and rear sides of the pressing parts 73, and the sliding rods 87 are in contact with the adjacent sliding frames 86. Second springs 85 are connected between the sliding frames 86 and the adjacent mounting plates 84.

[0032] It should be noted that the operator places the steel column to be shaped on the conveying roller 3, and the driving motor 2 drives the conveying roller 3 to rotate, conveying the steel column to the shaping station to the right. During the conveying process, as the pressing member 73 moves downward, at this time the sliding rod 87 moves downward synchronously. During the downward movement of the sliding rod 87, it will no longer block the sliding frame 86. In the initial state, the second spring 85 is in a stressed and stretched state. Under the action of the second spring 85, the sliding frame 86 will slide outward. At this time, the sliding frame 86 no longer limits the lifting frame 81. In the initial state, the first spring 82 is in a stressed and compressed state. Under the action of the first spring 82, the lifting frame 81 will move upward. At this time, relying on the blocking plate and the notch plate on the blocking frame, the steel column can be limited and blocked to ensure its accurate docking at the shaping position. As the shaping is completed, the shaping member 6 is pulled back by the multi-stage hydraulic cylinder 5. At this time, the steel column is blocked by the notch plate, so that the shaping member 6 quickly disengages from the surface of the steel column to avoid adhesion. Embodiment 2

[0033] On the basis of Embodiment 1, it further includes a supporting mechanism 9. The supporting mechanism 9 includes a supporting bracket 91. Three supporting brackets 91 are slidably arranged on the fixing frame 71. The supporting bracket 91 is used for supporting the steel column. Fixed rings 92 are installed at the front and rear parts of the fixing frame 71. A third spring 93 is connected between the fixed ring 92 and the supporting bracket 91. The third spring 93 is sleeved on the fixing frame 71. A friction member 94 is arranged in the middle of the supporting bracket 91. The friction member 94 is used to enhance the friction force of the steel column to avoid shaking or displacement during processing.

[0034] It should be noted that during the shaping process of the steel column, the supporting mechanism 9 and the pressing mechanism 7 cooperate to ensure the processing stability. When the steel column is conveyed to the shaping station, its own weight presses down the supporting bracket 91, causing the supporting bracket 91 to slide downward along the fixing frame 71 and compress the third spring 93. At this time, the friction member 94 in the middle of the supporting bracket 91 closely fits the bottom of the steel column, and the increased friction force prevents it from sliding laterally or rotating during shaping.

[0035] It further includes a discharging mechanism 10. The discharging mechanism 10 includes an installation frame 102. The installation frame 102 is installed between the two fixing frames 71 on the left side. A rotating roller 103 is rotatably connected to the installation frame 102. A connecting shaft 104 is installed on the rotating roller 103. A pulley assembly 101 is connected between the connecting shaft 104 and the rightmost conveying roller 3. The pulley assembly 101 is used for transmitting power.

[0036] It should be noted that after the steel column is finished with the shaping process, since the steel column is disengaged from the conveying roller 3 at this time and cannot be directly sent out through the conveying roller 3, the output shaft of the driving motor 2 can be controlled to rotate in the reverse direction at this time, so that the rotating roller 103 rotates under the action of the pulley assembly 101, and the steel column is output by relying on the rotating roller 103, so that the steel column contacts the conveying roller 3 again, thus achieving the effect of rapid discharging.

[0037] It further includes a guiding mechanism 11, and the guiding mechanism 11 includes a guiding plate 111. Two symmetrically arranged guiding plates 111 are provided on the upper side of the left part of the mounting table 1, and the guiding plate 111 is used for guiding the feeding of the steel column. Two limiting plates 112 are installed on the top of the mounting table 1, and the limiting plates 112 are used for guiding the steel column for limiting.

[0038] It further includes an adapting plate 12. The adapting plates 12 are connected to the left sides of the supporting brackets 91 respectively, and the adapting plate 12 is used for guiding the height difference of the steel column to avoid hard friction between the steel column and the supporting bracket 91.

[0039] A shaping use method of a steel column shaping machine device is as follows: Step 1: Place the steel column to be shaped on the conveying roller 3 on the left part of the mounting table 1. The guiding plate 111 and the limiting plate 112 guide it to be centered and positioned. Start the driving motor 2, and convey the steel column to the shaping station to the right through the conveying roller 3; Step 2: The single-stage hydraulic cylinder 72 of the pressing mechanism 7 pushes the arc-shaped pressing member 73 downward, so that the lifting frame 81 drives the blocking plate and the notch plate to move. After the steel column contacts the blocking plate of the lifting frame 81, the notch plate limits it to stop at the shaping position, and the supporting bracket 91 synchronously jacks up the friction member 94 to complete the two-way fixation; Step 3: The multi-stage hydraulic cylinder 5 drives the shaping member 6 to move, and applies force to correct the deformed part of the steel column. During the process, the third spring 93 of the supporting mechanism 9 adaptively adjusts the lifting force to ensure stability; Step 4: After the shaping is completed, the hydraulic cylinder retracts to drive the shaping member 6 to reset. The sliding frame 86 of the demoulding mechanism 8 resets to assist in separation. The driving motor 2 rotates in reverse, and drives the rotating roller 103 through the pulley assembly 101 to send the steel column to the left out to the conveying roller 3 to complete the discharging; Step 5: Each mechanism resets to the initial state to prepare for the next operation.
