Description

Technical Field

[0001] The invention relates to the technical field of steel cage welding, and in particular to a prefabricated stair steel cage forming welding device. Background Art

[0002] In the field of construction, before the pile foundation and pillars are cast and formed, it is necessary to first manufacture a cylindrical steel cage of the corresponding diameter, then place the steel cage in a round pit, and then pour concrete into the steel cage to form it; however, in the process of making the steel cage, it is often necessary to combine and weld multiple straight steel bars with multiple circular steel rings. This process is often carried out by manpower, which is time-consuming, labor-intensive and has certain risks.

[0003] Regarding the forming and welding process of the steel cage, the existing steel cage forming and welding device uses its own structure to fix the straight steel bars and the annular steel ring, and then welds the contact points through a handheld welding machine. Compared with manual welding of the steel cage, the steel cage forming and welding device greatly improves the efficiency of steel cage manufacturing; however, the existing steel cage forming and welding device can only form and weld steel cages of a specific diameter, and cannot achieve forming and welding of steel cages of different diameters through its own adjustment; therefore, a prefabricated staircase steel cage forming and welding equipment that can improve efficiency and manufacture steel cages of different diameters is needed to solve the shortcomings of the existing steel cage forming and welding devices.

[0004] For example, the patent with the announcement number CN115570301B provides a steel cage welding device, which includes a frame, a transverse reinforcement feeding mechanism, a longitudinal reinforcement feeding mechanism, a welding mechanism and a tensioning mechanism. The transverse reinforcement feeding mechanism and the longitudinal reinforcement feeding mechanism are used for feeding the reinforcement, and the welding mechanism is used for welding. This application can improve the accuracy of the welding position between the longitudinal reinforcement and the transverse reinforcement, and solve the problem that the longitudinal reinforcement of the steel cage is difficult to locate at the position of the transverse reinforcement. The cylindrical steel cage formed by the longitudinal and transverse reinforcements of this scheme has a fixed diameter, and cannot be automatically manufactured with steel cages of different diameters through autonomous adjustment of the device itself; this scheme can only manufacture steel cages with the longitudinal reinforcements outside the annular reinforcements, and cannot manufacture steel cages with the longitudinal reinforcements inside the annular reinforcements; the welding points of this scheme are on the outside of the steel cage, and the positions and numbers of the welding points cannot be adjusted accordingly according to actual conditions, and the welding strength cannot be improved; after the steel cage is welded, this scheme cannot assist in lifting the steel cage, and cannot further save manpower; the interval marking of this scheme is achieved by sticking labels on the steel bars. This method requires a large number of labels and is not suitable for large-scale steel cage production. It is also impossible to pre-adjust the stepping interval during the advancement of the steel cage. Summary of the invention

At this time, the push spring 315 will be compressed, and the arc-shaped elastic column 317 will limit the rotation of the blocking block 318 through elastic force, thereby limiting the forward and backward sliding of the annular steel bar 4.When the annular steel bar 4 is on the inner side of the straight steel bar 2, the eighth electric push rod 322 contracts and drives the sliding laser welding head 321 to move backward to the position where the first annular steel bar 4 contacts the straight steel bar 2, and the fourth electric push rod 304 extends forward to drive the fixed laser welding head 306 to move forward to determine the interval between the first annular steel bar 4 and the second annular steel bar 4, loosen the bolts on the variable control base 707, so that the lead screw 705 on the variable control assembly 701 can rotate freely, then pull the movable pin 302 off the forming slide 303 and the forming base 301, and then insert the movable pin 302 into the forming slide 303 and the forming wheel 310 to limit the rotation of the forming wheel 310, and then rotate the variable control wheel 706 in situ The screw 705 drives the rolling plate 501 to move forward through the one-way ball 503, and the rolling plate 501 drives the forming slide 303 and the forming wheel 310 to move forward through the rolling base 506 to adjust the position of the first annular steel bar 4 on the straight steel bar 2. After the adjustment is completed, the movable latch 302 is reinserted into the forming slide 303 and the forming base 301, and then the flip device 1 drives the forming base 301 to rotate on the forming base 301, so that the forming base 301 rotates to a vertical state, and the rear end of the straight steel bar 2 contacts the flip base 101, so that the straight steel bar 2 is lifted and aligned with each other, and then the bolts on the variable control base 707 are tightened so that the variable control wheel 706 cannot rotate freely. The control turntable 703 on the control device 7 is manually rotated, and the control turntable 703 drives the lead screw 705 to slide back and forth in the one-way ball 503 through the second connecting rod 702. The one-way ball 503 drives the rolling disk 501 of the rolling component 5 to rotate intermittently in one direction, and the rolling disk 501 drives the forming wheel 310 to rotate intermittently in one direction, so that the steel cage rotates intermittently. At this time, the sliding laser welding head 321 first welds the contact point between the first annular steel bar 4 and the straight steel bar 2 for the first time, and then the ninth electric push rod 602 of the forward component 6 drives the forward roller 603 to contact the steel cage, and then manually rotates the control pulley 704, and the control pulley 704 drives the double-layer pulley 605 to rotate through the first belt 8, and the double-layer pulley 60 5 drives the forward roller 603 to rotate, and the forward roller 603 drives the steel cage to move upward.

[0045] Specifically, Figure 2 , Figure 3 and Figure 5 As shown, the second electric push rod 103 on the flip base 101 contracts and drives the flip slider 104 to slide forward. The flip slider 104 drives the forming base 301 to flip through the first electric push rod 102 and the forming slider 309. After flipping to 45°, the third electric push rod 105 contracts and inserts the flip pin 106 into the first electric push rod 102 and the flip slider 104, so that the first electric push rod 102 cannot rotate around the flip slider 104. At this time, the first electric push rod 102 extends forward and the sixth electric push rod 308 retracts to drive the forming base 301 to flip to a vertical state.

During the insertion process of the straight steel bar 2, the two locking jaws 329 on the clamping assembly 311 are driven to flip inward, and then the bar magnet 330 on one locking jaw 329 adsorbs the clamping pin 328 in the other locking jaw 329, so that the clamping pin 328 is inserted into the locking jaw 329, so that the locking jaw 329 and the clamping slide 327 clamp the straight steel bar 2 together, and then the seventh electric push rod 314 is extended and retracted. The first connecting rod 312 drives the clamping assembly 311 and the expansion slide 313 to expand or contract synchronously to adjust the distance between the straight steel bars 2, thereby changing the diameter of the steel cage after forming, and then placing a plurality of annular steel bars 4 of corresponding diameters on the inner side or outer side of the expansion slide 313. At this time, the push spring 315 and the push slider 316 will be compressed backward, and the arc-shaped elastic column 317 will limit the rotation of the positioning block 318 through elastic force, thereby limiting the forward and backward sliding of the annular steel bar 4; when the annular steel bar 4 is on the inner side of the straight steel bar 2, the center sleeve 3 The eighth electric push rod 322 on 19 drives the welding slide ring 320 to slide backward, and the welding slide ring 320 drives the sliding laser welding head 321 to move backward to the position where the first annular steel bar 4 contacts the straight steel bar 2, and the fourth electric push rod 304 drives the fifth electric push rod 305 and the fixed laser welding head 306 to move forward, and the fixed laser welding head 306 drives the fixed laser welding head 306 to slide up and down, thereby determining the interval between the first annular steel bar 4 and the second annular steel bar 4; loosen the bolts on the variable control base 707 so that the lead screw 705 on the variable control assembly 701 can be The movable latch 302 is then pulled out from the forming slide 303 and the forming base 301, and then the movable latch 302 is inserted into the forming slide 303 and the forming wheel 310 to limit the rotation of the forming wheel 310; then the variable control wheel 706 and the lead screw 705 are rotated in situ, and the lead screw 705 drives the rolling plate 501 to move forward through the one-way ball 503, and the rolling plate 501 drives the forming slide 303 and the forming wheel 310 to move forward through the rolling base 506 to adjust the position of the first annular steel bar 4 on the straight steel bar 2;After the adjustment is completed, the movable latch 302 is reinserted into the forming slide 303 and the forming base 301, and then the flip device 1 drives the forming base 301 to rotate on the forming base 301, so that the forming base 301 rotates to a vertical state, and the rear end of the straight steel bar 2 contacts the flip base 101, so that the straight steel bar 2 is lifted and aligned with each other, and then the bolts on the variable control base 707 are tightened so that the variable control wheel 706 cannot rotate freely, and then the control turntable 703 is manually driven to rotate on the control pulley 704, and the control turntable 703 drives the lead screw 705 of the variable control assembly 701 to slide back and forth in the one-way ball 503 through the second connecting rod 702, and the one-way ball 503 of the rolling assembly 5 is When rotating clockwise, the one-way baffle plate 505 will limit the deformation of the elastic baffle rod 504. When the one-way ball 503 rotates counterclockwise, the elastic baffle rod 504 will deform after contacting the baffle column 502, so that the one-way ball 503 drives the rolling plate 501 to rotate intermittently in one direction through the elastic baffle rod 504 and the baffle column 502. The rolling plate 501 drives the forming wheel 310 to rotate intermittently in one direction, so that the steel cage rotates intermittently. At this time, the sliding laser welding head 321 will slide passively on the welding slide ring 320, so that the sliding laser welding head 321 remains in a vertical downward state, and then the sliding laser welding head 321 performs the first welding on the contact point between the first annular steel bar 4 and the straight steel bar 2, and then the forward assembly Part 6 drives the steel cage to move upward. When the first annular steel bar 4 reaches the fixed laser welding head 306, the fixed laser welding head 306 performs a second welding on the contact point between the first annular steel bar 4 and the straight steel bar 2, and the sliding laser welding head 321 performs a first welding on the contact point between the second annular steel bar 4 and the straight steel bar 2 to realize the forming welding function of the steel cage; when the annular steel bar 4 is outside the straight steel bar 2, the eighth electric push rod 322 drives the sliding laser welding head 321 to slide forward, and the fourth electric push rod 304 drives the fixed laser welding head 306 to slide backward, so that the positions of the fixed laser welding head 306 and the sliding laser welding head 321 are interchanged, and then the aforementioned forming welding process is repeated; the forming wheel 31 0When rotating, the forming slide 303 will slide relative to the rotating groove 323; the first slide groove 324 is used for the sliding of the clamping slide 327; the second slide groove 325 is used for the sliding of the expansion slide 313; the control base 307 is used for the installation of the control device 7; when the steel cage moves forward, the straight steel bar 2 drives the welded annular steel bar 4 to slide upward, and the annular steel bar 4 drives the blocking block 318 to flip outward, so that the annular steel bar 4 slides out of the expansion slide 313, and then the arc elastic column 317 drives the blocking block 318 to reset through elastic force, and the push spring 315 drives the remaining annular steel bars 4 to move upward, so that the uppermost annular steel bar 4 on the expansion slide 313 is always in the position of the first annular steel bar 4. ;
