Description

Technical Field

[0001] This invention relates to the field of building steel material production and processing technology, and in particular to a processing and forming device and processing method for box-shaped steel columns. Background Technology

[0002] Box-section steel columns are a commonly used building structural material, made of bent and welded steel plates, characterized by rectangular or square cross-sections. They are typically used in the main structure of buildings, serving a supporting and load-bearing function. Crane beams and work platform beams in factories, floor beams in multi-story buildings, and purlins in roof structures are all examples of box-section steel columns. Different specifications of box-section steel columns are also widely used for support in other construction processes. Depending on the usage environment and construction requirements, box-section steel columns need to be cut and ground to meet installation requirements. Existing automatic grinding equipment for box-section steel columns has poor automation and cannot adjust the grinding range according to the specifications of the box-section steel columns being ground, resulting in low applicability. Manual grinding, on the other hand, suffers from excessively low efficiency.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention. Example:

[0018] A processing and forming device for box-shaped steel columns, such as Figure 1 As shown, it includes: a mounting frame 1 and a control device; the mounting frame 1 is equipped with a placement mechanism 2, a fixing mechanism 3 and a processing mechanism 4; the placement mechanism 2 corresponds to the fixing mechanism 3, the box-shaped steel column is placed on the placement mechanism 2 by the operator, and the placement mechanism 2 transports the steel column to the designated position, and then the fixing mechanism 3 fixes the steel column; the processing mechanism 4 corresponds to the fixing mechanism 3 and is used to process the steel column; the control device is used to control the operation of the entire box-shaped steel column processing and forming device except for itself.

[0019] Specifically, such as Figure 2-4As shown, the placement mechanism 2 includes: a base plate 201; the base plate 201 is rotatably mounted on the bottom of the fixing mechanism 3; three sets of clamping plate assemblies are fixedly mounted on the base plate 201; each set of clamping plate assemblies includes a slide rail 202 fixedly mounted on the base plate 201, and the three slide rails 202 are on the same vertical plane; two clamping plates 203 are slidably mounted on each slide rail 202, and each clamping plate 203 is driven by a cylinder 204 fixedly mounted on the slide rail 202; the front end of the base plate 201 is rotatably mounted on the fixing mechanism 3. The placement mechanism 2 also includes a rotary drive assembly that drives the base plate 201 to rotate. Specifically, the base plate 201 has two lifting rings at its rear end. A spool 205 is rotatably mounted on the mounting frame 1 and driven by a motor 206 fixedly mounted on the mounting frame 1. There are two spools 205, each corresponding to one of the two lifting rings. A cable is wound around the spool 205, and the other end of the cable is fixed to the lifting ring. The motor 206 drives the spool 205 to rotate, thereby driving the base plate 201 to rotate. At the same time, in order to enable the base plate 201 to rotate to a vertical position, two clearance openings are provided on the base plate 201 to avoid the fixing mechanism 3.

[0020] The operator places the box-shaped steel column on the slide rail 202. The cylinder 204 moves the clamping plate 203 to fix the box-shaped steel column. The motor 206 drives the pulley 205 to rotate, which in turn drives the base plate 201 to rotate 90 degrees, moving the box-shaped steel column onto the fixing mechanism 3. The fixing mechanism 3 then fixes the box-shaped steel column, which is now in a vertical position.

[0021] Specifically, such as Figure 5-12 As shown, the fixing mechanism 3 includes: a second base plate 301 and a third cylinder 306; the second base plate 301 is vertically fixed on the mounting frame 1; a placement platform 314 is fixedly installed at the lower end of the second base plate 301; the placement platform 314 is rotatably connected to the front end of the first base plate 201; two support blocks 302 are fixedly installed on the second base plate 301 in the vertical direction, and the two support blocks 302 are located in the same vertical plane; each support block 302 is provided with a clamping device 1 and a clamping device 2 on both sides, which are used to fix the box-shaped steel column on the support block 302. The clamping device 1 and the clamping device 2 correspond to the two clearance openings on the first base plate 201 and will not affect the rotation of the first base plate 201.

[0022] After motor 206 drives base plate 201 to rotate 90 degrees, the lower end of the box-shaped steel column is placed on the placement platform 314. At the same time, one side of the box-shaped steel column abuts against the support block 302. Then, clamping device 1 and clamping device 2 fix the box-shaped steel column on the two support blocks 302 and the placement platform 314.

[0023] As a specific implementation method of this embodiment, such as Figure 8As shown, the clamping device includes: a mounting block 303 and a pressure plate 305; the mounting block 303 is fixedly mounted on the base plate 301 and located on one side of the support block 302; two cylinders 304 are fixedly mounted on the mounting block 303; a fixing rod 306 is fixedly mounted on the output end of the cylinder 304; a pressure plate 305 is rotatably mounted on each fixing rod 306 and driven by a motor 307 fixedly mounted on the fixing rod 306.

[0024] In the initial state, the pressure plate 305 is not directly above the support block 302, so it will not affect the placement of the box-shaped steel column on the support block 302. After the motor 206 drives the base plate 201 to rotate 90 degrees, one side of the box-shaped steel column abuts against the support block 302. The motor 307 drives the pressure plate 305 to rotate directly above the support block 302. The cylinder 304 drives the fixing rod 306 to move downward, which in turn drives the pressure plate 305 to move downward, fixing the box-shaped steel column on the support block 302.

[0025] As a specific implementation method of this example, such as Figure 9-12 As shown, the clamping device 2 includes: cylinder 308 and pressure plate 2 313; cylinder 308 is fixedly installed on base plate 2 301 and located on the other side of support block 302; mounting plate is fixedly installed on the outer side of cylinder 308; gear 1 309 is rotatably installed on mounting plate; rack 4 is provided on the output end of cylinder 308 to mesh with gear 1 309, and gear 1 309 is driven to rotate by cylinder 308; A fixing plate 310 is fixedly installed on gear 309; a fixing plate 311 is fixedly installed on fixing plate 310; three cylinders 312 are fixedly installed on fixing plate 311; a connecting plate is fixedly installed on the output end of the three cylinders 312, and a pressure plate 313 is fixedly installed on the connecting plate; the pressure plate 313 is used to fix the box-shaped steel column on the support block 302; as a specific embodiment of this example, the end of the pressure plate 313 that contacts the box-shaped steel column is L-shaped, which makes it easier to fix the box-shaped steel column.

[0026] Initially, pressure plate 2 313 is not directly above support block 302, so it does not affect the placement of the box-shaped steel column on support block 302. After motor 1 206 drives base plate 1 201 to rotate 90 degrees, one side of the box-shaped steel column abuts against support block 302. Cylinder 3 308 starts, and cylinder 3 308 drives gear 1 309 to rotate, which in turn drives pressure plate 2 313 to rotate, so that pressure plate 2 313 is directly above the box-shaped steel column. Cylinder 4 312 starts, driving pressure plate 2 313 to move downward, fixing the box-shaped steel column on support block 302. After the box-shaped steel column is fixed by clamping device 1 and clamping device 2, the placement mechanism 2 returns to the initial state.

[0027] Specifically, such as Figure 13-29 As shown, the processing mechanism includes: a sliding frame 401; a vertical slide rail 101 is provided on the mounting frame 1, and the sliding frame 401 is vertically slidably mounted on the slide rail 101; a rack 102 is also provided on the mounting frame 1, located at the middle position of the slide rail 101; a motor 402 is fixedly mounted on the sliding frame 401, and a gear 403 is fixedly mounted on the output end of the motor 402; the gear 403 meshes with the rack 102, and the motor 402 drives the sliding frame 401 to move up and down. A fixed frame 404 is horizontally slidably mounted on the lower end face of the sliding frame 401 and is driven by a cylinder 405 fixedly mounted on the mounting frame 1; a motor 406 and a fixed seat 407 are fixedly mounted on the fixed frame 404; a rotating seat 408 is rotatably mounted inside the fixed seat 407 and is driven by the motor 406; a rotating shaft 409 is fixedly mounted at the bottom end of the rotating seat 408; a grinding mechanism 1 is installed inside the rotating shaft 409; a rotating shaft 413 is fixedly mounted at the lower end of the rotating shaft 409; and a grinding mechanism 2 is fixedly mounted at the lower end of the rotating shaft 413. Because the axial position of different box-shaped steel columns is different when they are fixed on the support block 302, the position of grinding mechanism one and grinding mechanism two can be changed by moving the fixed frame 404 through cylinder five 405. This makes it applicable to different box-shaped steel columns, so that grinding mechanism one and grinding mechanism two can always be located at the axial position of the box-shaped steel column.

[0028] As a specific implementation method of this embodiment, such as Figure 17-20 As shown, the grinding mechanism includes: a motor 410, a bevel gear 411, and a bevel gear 412. The bevel gear 411 is rotatably mounted inside a rotating shaft 409. The motor 410 is fixedly mounted on a rotating seat 408, and a connecting shaft is fixedly mounted on the output end of the motor 410. The other end of the connecting shaft is fixedly connected to the bevel gear 411. The two bevel gears 412 are symmetrically rotatably mounted on the rotating shaft 409 and simultaneously mesh with the bevel gears 411. The bevel gears 412 are installed at a downward angle to facilitate chamfering and grinding of the upper outer side of the box-shaped steel column. A fixing block 4121 is fixedly mounted on each bevel gear 412. An electric telescopic rod 4122 is fixedly mounted on the fixing block 4121. A grinding block is fixedly mounted on the outermost end of the electric telescopic rod 4122. The grinding block is used to grind the box-shaped steel column. The two grinding blocks are driven by the motor 410 to rotate synchronously.

[0029] As a specific implementation method of this embodiment, such as Figure 21-29As shown, the second grinding mechanism includes: a mounting base 414, a swing rod 420, a grinder 421, and a swing rod 423; the mounting base 414 is fixedly installed at the lower end of the rotating shaft 413; a rotating seat 416 is rotatably mounted on the mounting base 414 and driven by a motor 417 fixedly mounted on the mounting base 414; the top of the sliding column 418 is vertically and elastically slidably mounted in the rotating seat 416 by three springs; the springs are compression springs; corresponding electromagnets 419 are fixedly installed on the sliding column 418 and the rotating seat 416; when the electromagnets 419 are energized, they attract each other, thereby driving the sliding column 418 to slide downward; when the electromagnets 419 are de-energized, the sliding column 418 returns to its original position under the action of the springs. The sliding column 418 has a rack section 2 and a rack section 3 from top to bottom; the swing rod has two sets, namely four swing rods 1 420 and four swing rods 2 423; Four swing rods 420 are rotatably mounted on a rotating base 416; each swing rod 420 has a gear 4 at its upper end and a grinder 421 fixedly mounted at its lower end; the grinder 421 is used to process the box-shaped steel column; the four gears 44 mesh with the rack 2 at the same time; in the initial state, the swing rods 420 are in a vertical state; the sliding column 418 moves downward, thereby driving the gear 44 to rotate, which in turn drives the swing rods 420 to rotate, so that the grinder 421 at the lower end of the swing rods 420 abuts against the box-shaped steel column, thereby grinding the box-shaped steel column; Four swing rods 423 are rotatably mounted on a rotating base 416. Each swing rod 423 has a gear 5 at its lower end and a grinder 421 fixedly mounted at its upper end. Four gears 422 are rotatably mounted on the rotating base 416 corresponding to the four gears 5, and the gears 422 mesh with their corresponding gears 5. All four gears 422 mesh with racks 3. Initially, the swing rods 423 are in a vertical position. The sliding column 418 moves downwards, thereby causing the gears 422 to rotate, which in turn drives the swing rods 423. The rotation causes the grinding machine 421 at the upper end of the swing rod 423 to abut against the box-shaped steel column, thereby grinding the box-shaped steel column. The sliding column 418 drives the swing rod 420 and the swing rod 423 to rotate, which can drive the grinding machine 421 to grind box-shaped steel columns of different models, thus increasing the applicability of this device. By setting the motor 417 to drive the rotating seat 416 to rotate, and then drive the grinding machine 421 to rotate, the situation where the length of the rotating shaft 413 is too long and thus affects the grinding effect of the grinding machine 421 can be avoided.

[0030] After the fixing mechanism 3 fixes the box-shaped steel column, the processing mechanism processes it. Motor 3 402 starts, driving the sliding frame 401 downwards, causing rotating shaft 1 409 and rotating shaft 2 413 to enter the box-shaped steel column. Simultaneously, motor 406 starts, driving rotating shaft 1 409 and rotating shaft 2 413 to rotate. Rotating shaft 1 409 drives two grinding blocks to rotate, and motor 5 410 starts, driving the two grinding blocks to rotate. When the grinding blocks contact the box-shaped steel column, they grind the column. Because the grinding blocks have an inclined angle, they can grind the chamfers on the box-shaped steel column. When rotating shaft 1 409 and rotating shaft 2 413 move to the designated position, the grinding mechanism 2 is located at the bottom of the box-shaped steel column. Electromagnet 419 is energized, driving the sliding column 418 downwards, which in turn drives the pendulum... The grinding machine 421 on the moving rod 420 and the swing rod 423 simultaneously abuts against the inner wall of the box-shaped steel column. The motor 417 starts, driving the grinding machine 421 to rotate and grind the inner wall of the box-shaped steel column. The motor 402 drives the sliding frame 401 to slowly move upward, thereby driving the grinding machine 421 to grind the inside of the box-shaped steel column from bottom to top. After grinding, the processing mechanism 4 resets, and the motor 206 drives the base plate 201 to rotate to a vertical position. The cylinder 204 drives the clamping plate 203 to fix the box-shaped steel column. Then the fixing mechanism 3 resets, releasing the box-shaped steel column. The cylinder 204 drives the box-shaped steel column to reset. The operator removes the ground box-shaped steel column and places another box-shaped steel column to be ground. The above operation is repeated to grind the new box-shaped steel column.

[0031] Specifically, such as Figure 28 As shown, the grinder 421 includes: a motor 4211 and a grinding block fixing rod 4214; the motor 4211 is fixedly installed on the upper end of the swing rod 423 or the lower end of the swing rod 420; a rotating rod 4212 is fixedly installed on the output end of the motor 4211; a connecting block 4213 is fixedly installed on the rotating rod 4212; the grinding block fixing rod 4214 is horizontally rotatably installed on the connecting block 4213; a grinding block is fixedly installed at the front end of the grinding block fixing rod 4214; the grinding block is driven by the motor 4211... The grinding block rotates to grind the box-shaped steel column. As a specific implementation of this embodiment, the grinding block fixing rod 4214 can only rotate 30 degrees left and right on the rotating block 4213. When the grinding block fixing rod 4214 rotates 30 degrees to the right or left, it abuts against one side of the rotating rod 4212. By rotating the grinding block fixing rod 4214, it is more convenient for the grinding machine 421 to grind the inner wall of the box-shaped steel column. Moreover, by limiting the rotation angle of the grinding block fixing rod 4214, the grinding effect of the grinding machine 421 will not be affected.

[0032] Cylinder 1 204, Motor 1 206, Cylinder 2 304, Motor 2 307, Cylinder 3 308, Cylinder 4 312, Motor 3 402, Cylinder 5 405, Motor 4 406, Motor 5 410, Motor 6 417, Electromagnet 419 and Motor 7 4211 are all electrically connected to the control device.

[0033] A method for processing box-type steel columns includes the following steps: Step a: The operator places the box-shaped steel column on the slide rail 202 and the cylinder 204 pushes the clamping plate 203 to fix it. Then the motor 206 starts and drives the base plate 201 to rotate and transport the box-shaped steel column into the fixing mechanism 3. Step b: After the box-shaped steel column is moved to the placement platform 314 and is in a vertical position, clamping device one and clamping device two are activated to fix the box-shaped steel column on the support block 302, and then the placement mechanism 2 is reset. Step c: While the motor 3 402 drives the sliding frame 401 to move downward, the grinding mechanism 1 is started to chamfer and grind the outer side of the upper end of the box-shaped steel column; after the rotating shaft 1 409 and rotating shaft 2 413 move downward to the designated position, the grinding device 2 is started, the motor 3 402 drives the sliding frame 401 to move upward, and cooperates with the grinding device 2 to complete the grinding of the inside of the box-shaped steel column. Step d: After grinding, the processing mechanism 4 is reset, and the motor 206 drives the base plate 201 to rotate to a vertical position; the cylinder 204 drives the clamping plate 203 to fix the box-shaped steel column; then the fixing mechanism 3 is reset, the box-shaped steel column is released, the cylinder 204 drives the box-shaped steel column to reset, the operator takes away the ground box-shaped steel column, and then places another box-shaped steel column that needs to be ground.

[0034] The above are merely preferred embodiments of this example, but the scope of protection of this example is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this example, based on the technical solution and inventive concept of this example, should be covered within the scope of protection of this example.
