Description

Technical Field

[0001] This invention relates to the fields of steel structure manufacturing and construction, and in particular to a steel column shaping machine and shaping method. Background Technology

[0002] In the steel structure manufacturing and construction industry, steel columns are important load-bearing components, and their straightness and shape accuracy directly affect the stability and safety of the overall structure. However, steel columns are prone to plastic deformation such as bending and twisting during transportation, storage or processing. Traditional manual straightening methods are inefficient and difficult to guarantee accuracy, while existing mechanical straightening equipment often suffers from problems such as inaccurate positioning, difficulty in demolding, and low degree of automation. In particular, when processing steel columns of different specifications, conventional equipment is difficult to achieve adaptive clamping and stable support, resulting in unsatisfactory straightening effects. In addition, the inconvenience of removing the shaped workpiece and the low material output efficiency also restrict production efficiency.

[0003] Therefore, in order to address the above problems, a steel column shaping machine and shaping method are now being developed. Summary of the Invention

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

[0005] The technical solution of this invention is as follows:

[0006] A steel column shaping machine includes an installation platform, a drive motor on the left side of the installation platform, four rotatable conveyor rollers on the left side of the installation platform, the output shaft of the drive motor connected to the rightmost conveyor roller, a placement platform on the front left side of the installation platform connected to the drive motor, a multi-stage hydraulic cylinder on the upper right side of the installation platform, a shaping component connected to the telescopic end of the multi-stage hydraulic cylinder, a clamping mechanism in the middle of the installation platform for clamping and limiting the steel column to be shaped, and a demolding mechanism on the installation platform for quickly separating the shaping component from the steel column, facilitating the operator to remove the shaped steel column.

[0007] As an improvement to the above solution, the clamping mechanism includes a fixed frame. Three fixed frames are installed on the upper side of the middle part of the mounting platform. Each fixed frame is equipped with a single-stage hydraulic cylinder, and each single-stage hydraulic cylinder has a clamping component on its telescopic end.

[0008] As an improvement to the above solution, the demolding mechanism includes a lifting frame, which is slidably arranged on the inner side of the middle of the mounting platform. Two guide columns symmetrically arranged on the left and right sides are installed in the middle of the mounting platform. The guide columns are slidably connected to the lifting frame. Two first springs are connected between the lifting frame and the guide columns. Two mounting plates symmetrically arranged front and back are bolted to the upper sides of the left and right sides of the mounting platform. Sliding frames are slidably connected to the mounting plates. The sliding frames can limit the lifting frame. Sliding rods are connected to the front and rear sides of the clamping member. The sliding rods are in contact with the adjacent sliding frames. A second spring is connected between the sliding frame and the adjacent mounting plate.

[0009] As an improvement to the above solution, a supporting mechanism is also included. The supporting mechanism includes a support frame, and three support frames are slidably arranged on the fixed frame. The support frames are used to support the steel column. Fixing rings are installed at both the front and rear parts of the fixed frame. A third spring is connected between the fixing ring and the support frame. The third spring is sleeved on the fixed frame. A friction element is provided in the middle of the support frame. The friction element is used to enhance the friction of the steel column and avoid shaking or displacement during processing.

[0010] As an improvement to the above solution, a discharge mechanism is also included. The discharge mechanism includes a mounting frame, which is installed between the two fixed frames on the left. A rotating roller is rotatably connected to the mounting frame, and a connecting shaft is installed on the rotating roller. A pulley assembly is connected between the connecting shaft and the rightmost conveying roller, and the pulley assembly is used to transmit power.

[0011] As an improvement to the above solution, a guiding mechanism is also included. The guiding mechanism includes guide plates. Two guide plates are symmetrically arranged on the upper left side of the mounting platform. The guide plates are used to guide the steel column during feeding. Two limiting plates are installed on the top of the mounting platform. The limiting plates are used to limit and guide the steel column.

[0012] As an improvement to the above solution, an adaptation plate is also included. The adaptation plate is connected to the left side of each support frame. The adaptation plate is used to guide the steel column according to the height difference and avoid hard friction between the steel column and the support frame.

[0013] As an improvement to the above solution, the inner side of the clamping member is an arc-shaped structure, which is used to clamp the steel column.

[0014] As an improvement to the above solution, a blocking plate is provided on the left side of the lifting frame and a notch plate is provided on the right side. Both the notch plate and the blocking plate are used to block the steel column.

[0015] A method for using a steel column shaping machine, comprising the following specific steps:

[0016] Step 1: Place the steel column to be shaped on the conveyor roller on the left side of the mounting platform. The guide plate and the limiting plate guide it to be centered. Start the drive motor and convey the steel column to the right to the shaping station through the conveyor roller.

[0017] Step 2: The single-stage hydraulic cylinder of the clamping mechanism pushes the arc-shaped clamping component down, causing the lifting frame to move the blocking plate and the notch plate. After the steel column contacts the blocking plate of the lifting frame, the notch plate limits it to stop in the shaping position. The support frame simultaneously lifts the friction component to complete the bidirectional fixation.

[0018] Step 3: Multi-stage hydraulic cylinders drive the shaping component to move and apply force to correct the deformed parts of the steel column. During the process, the third spring of the supporting mechanism adaptively adjusts the lifting force to ensure stability.

[0019] Step 4: After the shaping is completed, the hydraulic cylinder retracts and drives the shaped part to reset. The sliding frame of the demolding mechanism resets to assist separation. The drive motor reverses and drives the rotating roller through the pulley assembly to send the steel column to the left to the conveying roller, completing the discharge.

[0020] Step 5: Reset each mechanism to its initial state and prepare for the next operation.

[0021] By adopting the above technical solution, the advantages of the present invention are as follows:

[0022] 1. This invention achieves bidirectional fixation of the steel column by the coordinated action of the arc-shaped clamping component of the clamping mechanism and the friction component of the supporting mechanism, avoiding displacement or vibration during the forming process. After processing, the forming component and the workpiece can be quickly separated, reducing the risk of adhesion and significantly improving the straightness and shape accuracy after forming, thus meeting high-standard engineering requirements.

[0023] 2. This invention forms a continuous automated conveying system through conveying rollers, discharge mechanism and pulley assembly, realizing automatic feeding and discharging of steel columns, reducing manual intervention. The multi-stage hydraulic cylinder driven shaping parts cooperate with the synchronous action of the pressing mechanism to quickly complete the correction operation. Attached Figure Description

Detailed Implementation

[0033] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments. Example 1

[0034] A steel column shaping machine device, such as Figures 1-8 As shown, the system includes an installation platform 1, a drive motor 2 on the left side of the installation platform 1, four rotating conveyor rollers 3 on the left side of the installation platform 1, the output shaft of the drive motor 2 being connected to the rightmost conveyor roller 3, a placement platform 4 on the front left side of the installation platform 1, the placement platform 4 being connected to the drive motor 2, a multi-stage hydraulic cylinder 5 on the upper right side of the installation platform 1, a shaping component 6 connected to the telescopic end of the multi-stage hydraulic cylinder 5, a clamping mechanism 7 in the middle of the installation platform 1, the clamping mechanism 7 being used to clamp and limit the steel column to be shaped, and a demolding mechanism 8 on the installation platform 1, the demolding mechanism 8 being used to quickly separate the shaping component 6 from the steel column, making it easy for operators to remove the shaped steel column.

[0035] 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 conveyor roller 3 on the left side of the mounting platform 1. The drive motor 2 starts and drives the rightmost conveyor roller 3 to rotate through the output shaft, which in turn drives the other conveyor rollers 3 to rotate synchronously, so that the steel column is smoothly conveyed to the right to the bottom of the pressing mechanism 7. The pressing mechanism 7 then acts to firmly press the steel column onto the mounting platform 1, ensuring that there is no deviation during the shaping process. Subsequently, the multi-stage hydraulic cylinder 5 on the right side of the mounting platform 1 is activated, pushing the shaping part 6 downward to apply pressure to the deformed parts of the steel column, so that it gradually returns to the standard shape. After the shaping is completed, the demolding mechanism 8 acts to quickly separate the shaping part 6 from the steel column, avoiding difficulty in removal due to metal adhesion. Finally, the pressing mechanism 7 is reset, and the operator can easily remove the shaped steel column.

[0036] The clamping mechanism 7 includes a fixed frame 71. Three fixed frames 71 are installed on the upper side of the middle of the mounting platform 1. Each fixed frame 71 is equipped with a single-stage hydraulic cylinder 72. Each single-stage hydraulic cylinder 72 is provided with a clamping component 73 on its telescopic end. The inner side of the clamping component 73 is an arc-shaped structure, which is used to clamp the steel column.

[0037] 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 conveyor roller 3, starts the drive motor 2, and through the linkage of the four conveyor rollers 3, the steel column is conveyed to the right to the bottom of the pressing mechanism 7. At this time, the single-stage hydraulic cylinders 72 on the three fixed frames 71 in the middle of the mounting platform 1 act synchronously, pushing the arc-shaped pressing part 73 at its telescopic end to move downward, and pressing the steel column evenly from the top and the side. The arc-shaped structure of the pressing part 73 fits against the outer wall of the steel column to ensure that the pressing force is evenly distributed, avoid local deformation, and prevent the steel column from shifting or shaking during the shaping process.

[0038] The demolding mechanism 8 includes a lifting frame 81. The lifting frame 81 is slidably installed on the inner side of the middle of the mounting platform 1. A baffle plate is installed on the left side of the lifting frame 81, and a notch plate is installed on the right side. Both the notch plate and the baffle plate are used to block the steel columns. Two guide columns 83 are installed symmetrically on the left and right sides of the mounting platform 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 mounting plates 84 are symmetrically connected to the upper sides of the left and right sides of the mounting platform 1 by bolts. 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 clamping member 73. The sliding rods 87 are in contact with the adjacent sliding frames 86. A second spring 85 is connected between the sliding frames 86 and the adjacent mounting plates 84.

[0039] It should be noted that the operator places the steel column to be shaped on the conveyor roller 3, and the drive motor 2 drives the conveyor roller 3 to rotate, conveying the steel column to the right to the shaping station. During the conveying process, as the clamping part 73 moves downward, the sliding rod 87 moves downward synchronously. During the downward movement, the sliding rod 87 will no longer obstruct the sliding frame 86. In the initial state, the second spring 85 is under tension. 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 under compression. Under the action of the first spring 82, the lifting frame 81 will move upward. At this time, the blocking plate and notch plate on the blocking frame can limit and block the steel column, ensuring that it stops accurately at the shaping position. As the shaping is completed, the shaped part 6 is pulled back to its original position by the multi-stage hydraulic cylinder 5. At this time, the notch plate blocks the steel column, so that the shaped part 6 can quickly detach from the surface of the steel column and avoid adhesion. Example 2

[0040] Based on embodiment 1, a supporting mechanism 9 is also included. The supporting mechanism 9 includes a support frame 91. Three support frames 91 are slidably arranged on the fixed frame 71. The support frames 91 are used to support the steel column. Fixed rings 92 are installed on both the front and rear parts of the fixed frame 71. A third spring 93 is connected between the fixed ring 92 and the support frame 91. The third spring 93 is sleeved on the fixed frame 71. A friction element 94 is provided in the middle of the support frame 91. The friction element 94 is used to enhance the friction of the steel column and prevent shaking or displacement during processing.

[0041] It should be noted that during the steel column forming process, the supporting mechanism 9 and the pressing mechanism 7 work together to ensure processing stability. When the steel column is transported to the forming station, its own weight presses down on the supporting frame 91, causing the supporting frame 91 to slide downward along the fixed frame 71 and compress the third spring 93. At this time, the friction element 94 in the middle of the supporting frame 91 is in close contact with the bottom of the steel column, and the increased friction prevents it from sliding laterally or rotating during forming.

[0042] It also includes a discharge mechanism 10, which includes a mounting frame 102. The mounting frame 102 is installed between the two fixed frames 71 on the left side. A rotating roller 103 is rotatably connected to the mounting 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 to transmit power.

[0043] It should be noted that after the steel column has been shaped, it cannot be directly sent out by the conveyor roller 3 because it is no longer in contact with the conveyor roller 3. At this time, the output shaft of the drive motor 2 can be controlled to rotate in the opposite direction, so that the rotating roller 103 rotates under the action of the pulley assembly 101. The steel column is output by the rotating roller 103, so that the steel column contacts the conveyor roller 3 again, thereby achieving the effect of rapid material discharge.

[0044] It also includes a guide mechanism 11, which includes a guide plate 111. Two guide plates 111 are symmetrically arranged on the upper left side of the mounting platform 1. The guide plates 111 are used to guide the steel column to feed. Two limiting plates 112 are installed on the top of the mounting platform 1. The limiting plates 112 are used to limit and guide the steel column.

[0045] It also includes an adaptation plate 12. The left side of the support frame 91 is connected to the adaptation plate 12. The adaptation plate 12 is used to guide the height difference of the steel column and avoid hard friction between the steel column and the support frame 91.

[0046] A method for using a steel column shaping machine, comprising the following specific steps:

[0047] Step 1: Place the steel column to be shaped on the conveyor roller 3 on the left side of the mounting platform 1. The guide plate 111 and the limiting plate 112 guide it to be centered. Start the drive motor 2 and convey the steel column to the right to the shaping station through the conveyor roller 3.

[0048] Step 2: The single-stage hydraulic cylinder 72 of the clamping mechanism 7 pushes the arc-shaped clamping part 73 down, causing the lifting frame 81 to move the blocking plate and the notch plate. After the steel column contacts the blocking plate of the lifting frame 81, the notch plate limits it to stop in the shaping position. The support frame 91 simultaneously lifts the friction part 94 to complete the bidirectional fixation.

[0049] Step 3: The multi-stage hydraulic cylinder 5 drives the shaping component 6 to move and apply force to correct the deformed parts of the steel column. During the process, the third spring 93 of the supporting mechanism 9 adaptively adjusts the lifting force to ensure stability.

[0050] Step 4: After the shaping is completed, the hydraulic cylinder retracts and drives the shaped part 6 to reset. The sliding frame 86 of the demolding mechanism 8 resets to assist separation. The drive motor 2 reverses and drives the rotating roller 103 through the pulley assembly 101 to send the steel column to the left to the conveying roller 3, thus completing the discharge.

[0051] Step 5: Reset each mechanism to its initial state and prepare for the next operation.

[0052] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention. Therefore, the scope of the invention should be limited only by the appended claims.
