[0002] The floor slab steel frame is composed of steel bars combined together with concrete to form the grid of the floor slab. The floor slab steel frame is mainly composed of two symmetrically bent web members welded together with three chords arranged in a triangle. Compared with traditional solid floor slabs, it has a lighter weight and can effectively reduce the overall weight of the building. Therefore, its scope of use is becoming more and more extensive.

[0003] The processing method of the floor slab steel bar skeleton includes the following steps: S1. synchronously conveying the chord and the web to the welding station for welding, S2. bending the bottom of the web by bending equipment during the continuous conveying process, S3. cutting the formed parts to a fixed length according to the design requirements; the following technical problems exist in the existing technology: 1. During the bending process, the conveying mechanism only realizes the component conveying function, and lacks a positioning and restraining mechanism for the chord and the web. Therefore, during the bending process, the chord and the web are very likely to be deformed due to force, thereby affecting the quality of the floor slab steel bar skeleton; 2.

However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] See Figure 1 A floor steel frame forming and processing equipment includes a support base 1, a limiting unit 2 and a bending unit 3.

A conveying frame 24 for conveying the web rod is provided on the mounting frame 23. A guide frame 25 is provided at the lower end of the fixed plate 22 to cooperate with the mounting frame 23 to limit and guide the chord rod.

A bidirectional screw 21 is connected to the two vertical plates 13 for rotation, and a distance control cylinder 31 is fixedly installed on the opposite ends of the two vertical plates 13.

[0032] See Figure 2 and Figure 3 A rectangular guide rod 221 is fixedly installed on one end of the fixed plate 22 close to the vertical plate 13, and the guide rod 221 is connected to the vertical plate 13 in a forward and backward sliding manner.

[0033] See Figure 3 The mounting frame 23 includes a close-fitting plate 231, and the two fixing plates 22 are fixedly mounted with close-fitting plates 231 with a right-angled trapezoidal cross section at the opposite ends. The lower sides of the opposite ends of the two close-fitting plates 231 are provided with arc grooves.

[0034] See Figure 2 The conveying frame 24 includes a rotating column 241, and a plurality of inclined rotating columns 241 are evenly connected and rotated on the close plate 231. The rightmost rotating column 241 is longer than the other rotating columns 241. The rightmost rotating column 241 is used to connect with an external motor. The inclination angle of the rotating column 241 is the same as the inclination angle of the inclined surface of the close plate 231. A sprocket 242 is fixedly installed on the rotating column 241. The sprockets 242 on the same close plate 231 are connected through two toothed chain belts 243 arranged up and down. An anti-slip ring plate 244 is fixedly installed on the sprocket 242 and located at the lower end of the toothed chain belt 243. The toothed chain belt 243 extends out of the inclined surface of the close plate 231.

[0035] See Figure 2 and Figure 5 The guide frame 25 includes a threaded rod 251, the lower end of the fixed plate 22 is rotatably connected to the threaded rod 251, the lower end of the threaded rod 251 is fixedly installed with an anti-slip circular plate 252, and a rectangular block 253 is threadedly connected to the threaded rod 251. Rectangular plates 254 are fixedly installed at the opposite ends of the two rectangular blocks 253, and arc grooves are provided on the upper sides of the opposite ends of the two rectangular plates 254. Circular insertion rods 255 are fixedly installed on the upper ends of the rectangular plates 254, and the circular insertion rods 255 are connected to the close-fitting plate 231 in an up and down sliding manner; the anti-slip circular plate 252 prevents the rectangular block 253 from detaching from the threaded rod 251 during movement.

[0036] See Figure 4 and Figure 5 The control frame 26 includes a bevel gear 261, and a bevel gear 261 is fixedly installed on the upper end of the threaded rod 251. A bevel gear 262 is rotatably connected to the fixed plate 22. The bevel gear 262 is meshed with the bevel gear 261. A control handle 263 is fixedly installed on the left end of the bevel gear 262, and the control handle 263 rotates through the fixed plate 22; the threaded rod 251 is rotated by rotating the control handle 263. If the operating space is sufficient, the control frame 26 can be omitted and the threaded rod 251 can be rotated directly by hand.

[0037] The processing equipment can bend the continuous welded steel skeleton conveyed from right to left in the assembly line, and can also bend the welded steel skeleton of shorter length. The continuous welded steel skeleton in the assembly line continues to be conveyed from right to left along the conveying equipment in the assembly line, thereby continuing to move from right to left along the triangular plate 14. At this time, the toothed chain belt 243 moves with the moving steel skeleton to play an auxiliary conveying role. The welded steel skeleton of shorter length can be directly delivered to the triangular plate 14 through an external belt conveyor. At this time, the bidirectional screw 21 is driven to rotate by an external motor, driving the fixed plate 22 to move toward each other until the toothed chain belt 243 on the close-fitting plate 231 contacts the web on the steel skeleton. The sprocket 242 is driven to rotate by the external motor, thereby driving the toothed chain belt 243 to move, and the shorter welded steel skeleton is transported. The control handles 263 on the front and rear sides are rotated to drive the threaded rod 251 to rotate, so that the rectangular block 253 moves up until the arc groove on the rectangular plate 254 contacts the chord on the steel skeleton. During the entire bending and conveying process, the auxiliary conveying function of the toothed chain belt 243 always exists.

[0038] See Figure 2 、 Figure 3 、 Figure 5 and Figure 6 The telescopic end of the distance control cylinder 31 on the rear side is fixedly installed with a bending plate 1 311, and the telescopic end of the distance control cylinder 31 on the front side is fixedly installed with a U-shaped bracket 312. The rear end of the U-shaped bracket 312 passes through the bending plate 1 311 and is fixedly installed with a bending plate 2 313. The telescopic end of the distance control cylinder 31 on the rear side passes through the bending plate 2 313.

[0039] See Figure 2 and Figure 3 The upper sides of the opposite ends of the bending plate 1 311 and the bending plate 2 313 are provided with inclined surfaces, and the inclination angle of the inclined surfaces is the same as the inclination angle of the inclined surface of the close-fitting plate 231.

[0040] See Figure 3 、 Figure 5 and Figure 6 When the part to be bent completely enters both sides of the triangular plate 14, the distance control cylinders 31 on the front and rear sides drive the bending plate 1 311 and the bending plate 2 313 to move toward the front and rear sides respectively, wherein the bending plate 1 311 moves forward and cooperates with the front rectangular plate 254 to bend the bottom of the front web, and the bending plate 2 313 moves backward and cooperates with the rear rectangular plate 254 to bend the bottom of the rear web. After the bending is completed, the distance control cylinder 31 drives the bending plate 1 311 and the bending plate 2 313 to return to their initial positions.

[0041] See Figure 2 and Figure 5 The two toothed chain belts 243 have opposite movement directions, and a plurality of arc rollers 141 are connected in the arc groove along their linear uniform rotation. A support plate 121 is fixedly installed on the right end of the right-angle bracket 12 on the left. The horizontal plane height of the upper end of the support plate 121 is the same as the horizontal height of the upper end of the bending plate 1 311; the support plate 121 is used to reshape the bent part of the bottom of the web to further avoid rebound of the bent part of the bottom of the web.

[0042] At this time, the external motor drives the rightmost rotating column 241 to rotate, thereby driving the toothed chain belt 243 to rotate, and the toothed chain belts 243 on the front and rear sides move in opposite directions, thereby transporting the steel skeleton to the left. When the bent web on the steel skeleton moves to the left, the bottom of the bent web is limited and shaped by the support plate 121. During the whole process, the arc rollers 141 on the multiple arc grooves are used to reduce the friction resistance during the transportation of the steel skeleton, and the chord on the steel skeleton is limited and shaped. The close-fitting plate 231 cooperates with the toothed chain belt 243 to limit and shape the welded web while transporting the steel skeleton, thereby ensuring the quality of the welded and bent steel skeleton.

[0043] The working principle of the present invention is as follows: Step 1: Move the welded steel frame from right to left along the support base 1. At this time, the bidirectional screw 21 is driven to rotate by an external motor, driving the fixed plate 22 to move toward each other until the conveying frame 24 on the mounting frame 23 contacts the web on the steel frame, and the guide frame 25 is driven upward by the control frame 26 until the guide frame 25 contacts the two chords at the bottom of the steel frame.

[0044] Step 2: At this time, the distance control cylinders 31 on the front and rear sides drive the bending frame 32 to move, thereby bending the web, and the distance control cylinders 31 drive the bending frame 32 to return to the initial position.

[0045] Step 3: At this time, the conveying racks 24 on the front and rear sides are driven by an external motor to move in opposite directions, thereby conveying the steel skeleton to the left. When the bent webs on the steel skeleton move to the left, the distance control cylinder 31 continues to drive the unbent steel skeleton to move to the left and continue to bend. The mounting rack 23 cooperates with the conveying rack 24. While conveying the steel skeleton, the welded webs are limited and shaped, thereby ensuring the quality of the welded and bent steel skeleton.
