A smart welding equipment for processing construction steel

Abstract

This invention relates to the field of building steel processing technology, and particularly to an intelligent welding device for building steel processing. It includes a base, on the top of which are symmetrically arranged two sets of auxiliary processing mechanisms. The invention controls a second rotating ring to drive a first grinding block to rotate. The side of the first grinding block treats the steel end face for rust and impurities. When the steel is cylindrical, the high-speed rotation of the first grinding block treats the side of the steel. When the steel is rectangular, the corresponding second grinding block is controlled to move to both sides of the first grinding block to adapt to the width of the steel side. Subsequently, several sets of electric telescopic rods are controlled to drive the second processing ring to reciprocate, thus treating the side of the steel. This not only removes rust or impurities from the weld joints of the steel, avoiding the risk of weld breakage, but also adapts to building steel of different shapes, improving the pre-treatment effect of the weld joints.

Description

Technical Field

[0001] This invention belongs to the field of building steel processing technology, and specifically relates to an intelligent welding device for building steel processing. Background Technology

[0002] Construction steel can generally be divided into steel for steel structures and reinforcing steel for reinforced concrete structures. Steel for steel structures mainly includes ordinary carbon structural steel and low-alloy structural steel. Varieties include structural steel sections, steel pipes, and reinforcing bars. Structural steel sections include angle steel, I-beams, and channel steel. Regardless of the type of steel, welding or cutting is required in actual use depending on the working conditions.

[0003] A search revealed that Chinese Patent Publication No. CN117548825B, published on March 15, 2024, discloses a steel processing equipment for construction, comprising a laser arc welding mechanism and a clamping mechanism that cooperate with each other. The laser arc welding mechanism is used to weld I-beams clamped on the clamping mechanism. The clamping mechanism includes a guide member and two bases that can move symmetrically along the guide member. A one-way transmission component and a clamp are mounted on the bases with damping rotation. The one-way transmission component drivesly connects the guide member and the clamp. This invention can effectively realize the automatic welding of I-beams for construction. Furthermore, the two sets of clamps in the clamping mechanism only rotate when they are far apart. Based on this, on the one hand, the proximity of the two sets of clamps ensures the integrity of the welding between the web and the flange; on the other hand, the distance between the two sets of clamps enables the automatic flipping of the I-beam, thereby improving welding efficiency.

[0014] Furthermore, each set of first electric push rods is driven to a set of electric turntables at its output end; each set of electric turntables is driven to a set of auxiliary processing blocks at its output end; each set of auxiliary processing blocks has a set of grooves on one side wall; the inner wall of the grooves is arc-shaped and toothed.

[0015] Furthermore, the welding slag collection mechanism includes a collection seat; two sets of second translational guide rails are symmetrically arranged on the top two sides of the collection seat; two sets of closed boxes are symmetrically arranged on the top of the collection seat; each set of closed boxes is connected to the two sets of second translational guide rails; a set of closed cavities is opened on the opposite side wall of the two sets of closed boxes; the bottom of each set of closed cavities is an open structure; two sets of feeding channels are symmetrically arranged on the inner walls of both sides of each set of closed cavities; the two sets of feeding channels on the same side combine to form a circular hole structure.

[0019] The beneficial effects of this invention are:

[0020] 1. By controlling the second rotating ring to drive the first grinding block to rotate, the side of the first grinding block treats the rust and impurities on the end face of the steel. When the steel is cylindrical, the high-speed rotation of the first grinding block can treat the side of the steel. When the steel is rectangular, the corresponding second grinding block is controlled to move to both sides of the first grinding block to adapt to the width of the side of the steel. Then, by controlling several sets of electric telescopic rods to drive the second processing ring to move back and forth, the side of the steel can be treated. This not only realizes the treatment of rust or impurities at the welded joint of the steel, avoiding the risk of breakage at the weld, but also can adapt to different shapes of building steel, improving the pretreatment effect of the welded joint.

[0021] 2. By controlling the movement of the welding clamp through the top cover to the material feeding chamber, it can not only automatically clamp the welding rods and complete the automatic feeding work, but also avoid contact with air when idle. At the same time, the welding work is carried out in the closed space of the welding slag collection mechanism. The excess heat generated by the welding work can be introduced into the drying chamber through the air pump. Several sets of ventilation channels dry several sets of welding rods, avoiding the impact of excessive humidity of the welding rods on the welding work. This not only improves the preservation effect of the welding rods, but also realizes heat recovery.

[0022] 3. The two sets of building steel are joined together above the collection seat. Then, the two sets of enclosed boxes are merged to make the welding port a closed space. The sealing airbag is inflated and attached to the outer wall of the steel to further improve the sealing effect. Then, the welding clamp holds the welding rod and welds the steel joint through the welding channel. Since the welding work is in a closed space, it can not only avoid cracking caused by uneven temperature or rapid temperature change of the weld, but also avoid light pollution and slag spatter.

[0023] 4. One end of the steel is fed through the guide chute at the top of the guide block to the space between two sets of vertical pinch rollers. After passing between two sets of horizontal pinch rollers, it is then fed through two more sets of vertical pinch rollers. This achieves the straightening of the steel during the feeding process. The height of the guide block and the two sets of horizontal pinch rollers can be adjusted automatically, so that the axial height of the steel can always be kept consistent when welding steel of different sizes, thus improving the feeding effect of the welding equipment.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Figure 1 As shown, an arc welding mechanism 2 is provided on one side edge of the top of the base 1; two sets of auxiliary processing mechanisms 4 are symmetrically provided on the top of the base 1; a welding slag collection mechanism 3 is provided at the center of the top of the base 1; and two sets of self-adjusting feeding mechanisms 5 are symmetrically provided on both sides edge of the top of the base 1.

[0038] When welding structural steel, two sets of structural steel are fed through a self-adjusting feeding mechanism 5. After surface and end treatment by two auxiliary processing mechanisms 4, the steel is joined together in the enclosed space of the slag collection mechanism 3. Then, the arc welding mechanism 2 is controlled to weld the two sets of structural steel.

[0039] For example, such as Figure 2 , Figure 3 and Figure 4 As shown, the arc welding mechanism 2 includes a lifting module 201; an electric slide table 202 is drivenly connected to the output end of the lifting module 201; a movable mounting base 203 is drivenly connected to the bottom of the electric slide table 202; a welding clamp 204 is provided at the bottom of the movable mounting base 203; a material storage box 205 is provided on one side wall of the lifting module 201; a top cover 206 is provided on the top of the material storage box 205; an air pump 207 is provided on one side wall of the material storage box 205; the input end of the air pump 207 is connected to the welding slag collection mechanism 3; a material taking chamber 208 is opened at the top of the material storage box 205; and a material taking chamber 208 is located below the material taking chamber 208. A drying chamber 209 is provided; a rotating plate 210 is provided between the material receiving chamber 208 and the drying chamber 209; a number of material receiving through holes 211 are arranged in a ring array on the rotating plate 210; a rotating base 212 is provided on the bottom inner wall of the drying chamber 209; a number of material storage pipes 213 are arranged in a ring array between the rotating base 212 and the rotating plate 210; both ends of each group of material storage pipes 213 are connected to the rotating base 212 and the rotating plate 210 respectively, and are connected to a corresponding group of material receiving through holes 211; a number of ventilation slots 214 are arranged in a ring array on the outer wall of each group of material storage pipes 213.

[0040] For example, such as Figure 5 As shown, the welding slag collection mechanism 3 includes a collection seat 301; two sets of second translation guide rails 302 are symmetrically arranged on both sides of the top of the collection seat 301; two sets of closed boxes 303 are symmetrically arranged on the top of the collection seat 301; each set of closed boxes 303 is connected to the two sets of second translation guide rails 302; a set of closed cavities is opened on the opposite side wall of each set of closed boxes 303; the bottom of each set of closed cavities is an open structure; two sets of feeding channels are symmetrically arranged on the inner walls of both sides of each set of closed cavities. 304; Two sets of feed channels 304 on the same side are combined to form a circular hole structure; Each set of feed channels 304 is provided with a set of sealing airbags 306; The cross-section of each set of sealing airbags 306 is fan-shaped; A set of welding channels 305 is opened on the top inner wall of each set of closed cavities; A collection groove 307 is opened on the top of the collection seat 301; The collection groove 307 is connected to the input end of the air pump 207; A collection box 308 is movably inserted through the bottom inner wall of the collection groove 307.

[0041] During the welding of structural steel, two sets of structural steel are joined above the collecting seat 301. Then, the two sets of enclosed boxes 303 are merged, ensuring the welding ports are within a closed space. The sealing airbag 306 is inflated and adheres to the outer wall of the steel, further enhancing the sealing effect. The lifting module 201 moves the welding clamp 204 vertically, and the electric slide 202 moves it horizontally. The welding clamp 204 holds the welding rod (using arc welding technology; other related structures such as arc welding machines, welding cables, grounding clamps, and controllers are existing technologies and will not be described here). The two sets of welding channels 305 allow welding of the two sets of structural steel. Welding of steel joints is carried out in a closed space, which not only avoids cracking caused by uneven weld temperature or rapid temperature changes, but also avoids light pollution and slag spatter. The welding work is carried out in the closed space of the slag collection mechanism 3. The excess heat generated by the welding work can be introduced into the drying chamber 209 by the air pump 207. Several sets of ventilation channels 214 are used to dry several sets of welding rods, avoiding the influence of excessive humidity of the welding rods on the welding work. At the same time, by controlling the movement of the welding clamp 204 through the top cover 206 to the material picking chamber 208, it can not only clamp the welding rods by itself, but also complete the automatic material feeding work, which not only improves the preservation effect of the welding rods, but also realizes heat recovery.

[0042] For example, such as Figure 6 and Figure 7As shown, the auxiliary processing mechanism 4 includes a connecting base plate 401; the connecting base plate 401 is movably mounted on the top of the base 1; a connecting column 402 is provided on the top of the connecting base plate 401; a first processing ring 403 is provided on the top of the connecting column 402; a first rotating ring 404 is provided on the inner wall of the first processing ring 403; two sets of first translation guide rails 412 are symmetrically arranged on the inner wall of the first rotating ring 404; a set of first electric push rods 405 is provided in each set of first translation guide rails 412; a set of electric turntables 413 is drivenly connected to the output end of each set of first electric push rods 405; a set of auxiliary processing blocks 414 is drivenly connected to the output end of each set of electric turntables 413; each set of auxiliary processing blocks 414... A set of grooves is formed on one side wall of the processing block 414; the inner wall of the groove is arc-shaped and toothed; a number of electric telescopic rods 406 are arranged in a ring array on one side wall of the first processing ring 403; a second processing ring 407 is driven to the output end of the number of electric telescopic rods 406; a second rotating ring 408 is provided on the inner wall of the second processing ring 407; four sets of second electric push rods 409 are arranged in a ring array on the inner wall of the second rotating ring 408; a set of first grinding blocks 410 is driven to the output end of each set of second electric push rods 409; a set of translation grooves is formed on one side wall of each set of first grinding blocks 410; two sets of second grinding blocks 411 are symmetrically arranged in the translation grooves.

[0043] For example, such as Figure 8 and Figure 9 As shown, the self-adjusting feeding mechanism 5 includes a feeding seat 501; a first lifting guide rail 502 is provided on one side wall of the feeding seat 501; a guide block 503 is provided inside the first lifting guide rail 502; a guide groove 504 is provided on the top of the guide block 503; a feeding through groove 505 is provided on one side wall of the feeding seat 501; two sets of vertical pinch rollers 506 are respectively provided at both ends of the feeding through groove 505; two sets of second lifting guide rails 507 are symmetrically provided on the inner walls of both sides of the feeding through groove 505; two sets of lifting plates 508 are symmetrically provided inside the two sets of second lifting guide rails 507; and two sets of horizontal pinch rollers 509 are provided between the two sets of lifting plates 508.

[0044] During the welding of structural steel, one end of the steel is fed through the guide groove 504 at the top of the guide block 503 to the space between two sets of vertical clamping rollers 506. After passing between two sets of horizontal clamping rollers 509, it is then clamped by another two sets of vertical clamping rollers 506 for feeding. This achieves the straightening of the steel during the feeding process. The height of the guide block 503 and the two sets of horizontal clamping rollers 509 can be adjusted automatically, ensuring that the axial height of the steel remains consistent when welding steel of different sizes, thus improving the feeding efficiency of the welding equipment. Subsequently, the straightened structural steel passes through the auxiliary processing mechanism 4. Two sets of first electric push rods 405 drive a corresponding set of auxiliary processing blocks 414 to abut against the outer wall of the structural steel, forming an alternating clamping action. This allows the steel to rotate. Since the structural steel has been straightened, the welding end face will not shift during rotation. Furthermore, the structural steel is a threaded... When reinforcing steel bars are being processed, two sets of auxiliary processing blocks 414 can rotate and fit into the threads of the steel. During the feeding process, impurities in the thread grooves are cleaned. When the end face of the steel reaches the second processing ring 407, the first grinding block 410 is rotated by controlling the second rotating ring 408. The side of the first grinding block 410 treats the rust and impurities on the end face of the steel. When the steel is cylindrical, the high-speed rotation of the first grinding block 410 can treat the side of the steel. When the steel is rectangular, the corresponding second grinding block 411 is moved to both sides of the first grinding block 410 to adapt to the width of the side of the steel. Then, by controlling several sets of electric telescopic rods 406 to drive the second processing ring 407 to move back and forth, the side of the steel can be treated. This not only achieves the treatment of rust or impurities at the welded ends of the steel, avoiding the risk of breakage at the weld, but also adapts to different shapes of building steel, improving the pretreatment effect of the welded ends.

[0045] By controlling the second rotating ring 408 to drive the first grinding block 410 to rotate, the side of the first grinding block 410 is used to treat rust and impurities on the end face of the steel. When the steel is cylindrical, the high-speed rotation of the first grinding block 410 can treat the side of the steel. When the steel is rectangular, the corresponding second grinding block 411 is controlled to move to both sides of the first grinding block 410 to adapt to the width of the side of the steel. Then, by controlling several sets of electric telescopic rods 406 to drive the second processing ring 407 to move back and forth, the side of the steel can be treated. This not only realizes the treatment of rust or impurities at the welded joint of the steel, avoiding the risk of breakage at the weld, but also can adapt to different shapes of building steel, improving the pretreatment effect of the welded joint.

[0046] By controlling the movement of the welding clamp 204 through the top cover 206 to the material picking chamber 208, it can not only automatically clamp the welding rod and complete the automatic feeding work, but also avoid contact with air when idle. At the same time, the welding work is carried out in the closed space of the welding slag collection mechanism 3. The excess heat generated by the welding work can be introduced into the drying chamber 209 by the air pump 207. Several sets of ventilation channels 214 are used to dry several sets of welding rods, avoiding the influence of excessive humidity of the welding rods on the welding work. This not only improves the preservation effect of the welding rods, but also realizes heat recovery.

[0047] Two sets of building steel are joined above the collection seat 301. Then, the two sets of enclosed boxes 303 are merged to make the welding port a closed space. The sealing airbag 306 is inflated and attached to the outer wall of the steel to further improve the sealing effect. Then, the welding clamp 204 holds the welding rod and welds the steel joint through the welding through slot 305. Since the welding work is in a closed space, it can not only avoid cracking caused by uneven weld temperature or excessive temperature change, but also avoid light pollution and slag spatter.

[0048] One end of the steel is fed between two sets of vertical clamping rollers 506 via the guide groove 504 at the top of the guide block 503. After passing between two sets of horizontal clamping rollers 509, it is then clamped by another two sets of vertical clamping rollers 506 for feeding. This achieves the straightening of the steel during the feeding process. The height of the guide block 503 and the two sets of horizontal clamping rollers 509 can be adjusted automatically, so that the axial height of the steel can always be kept consistent when welding steel of different sizes, thus improving the feeding effect of the welding equipment.
