Description

Technical Field

[0001] This utility model belongs to the technical field of steel bar forming equipment, and in particular relates to a ring bar processing and forming equipment. Background Technology

[0002] Prefabricated steel reinforcement cages eliminate the time spent tying steel cages on-site, greatly improving work efficiency. Prefabricating the steel cages for casting in the factory reduces the impact of weather conditions, and factory construction allows for precise measurement and welding using various equipment, saving materials and ensuring product quality. Compared to prefabricated floor slabs, prefabricated steel reinforcement cages can be cast on-site, ensuring tightness at the joints between floor slabs and resulting in better quality.

[0003] For shear walls used within the wall structure, the steel reinforcement cage of the column structure consists of vertical bars and ring bars sleeved on the outside of the vertical bars, forming the frame of the column structure. After on-site assembly, concrete is poured. Currently, the ring bars are formed by bending short bars, with an inward bend at the joint side, resulting in staggered joints. This approach is not very robust, and the intersecting bars easily waste steel. Utility Model Content

[0004] The purpose of this invention is to provide a ring-shaped reinforcement processing and forming equipment to improve the supporting strength of the ring-shaped reinforcement while reducing the use of steel.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A ring-shaped rib forming equipment includes a base, a square mold fixed on the upper side of the base, the mold being a plate structure, a first roller installed at the corresponding corner position, and a rotating shaft installed on the base at the corresponding position of the first roller.

[0007] A clamp is fixed on the upper side of the base corresponding to the side of the mold, which is used to clamp and fix the steel bars;

[0008] It also includes a wrench for bending steel bars, with a handle at the rear end and shaft holes at the front and rear for connecting a rotating shaft for rotation. A second roller is installed near the shaft hole of the wrench.

[0009] Furthermore, the mold has slots on all four sides. The mold includes upper and lower mold plates. The lower mold plate is fixed to the base, and the upper mold plate is detachable. There is a sandwich layer between the upper and lower mold plates. A support column is provided between the lower mold plate and the upper mold plate. The support column has a limiting step, its lower end is fixed to the lower mold plate, and its upper end has a stud for passing through the upper mold plate and being fixed by a nut.

[0010] Furthermore, both the first roller and the second roller have axles and arc-shaped grooves on their surfaces to match the sides of the reinforcing bars.

[0011] Furthermore, the clamp includes a fixed clamping block and a movable clamping block. Both the fixed and movable clamping blocks have side clamping grooves with arc-shaped side projections. A screw is mounted on the back side of the movable clamping block, and a fixing block is provided on the base corresponding to the position of the screw. The fixing block has a threaded sleeve through which the screw passes, and the end of the screw is rotatably connected to the movable clamping block. The movable clamping block has limiting rods on both sides corresponding to the screw, and the fixing block has limiting holes through which the limiting rods pass.

[0012] This invention offers the following advantages: It uses a mold to shape the reinforcing steel bar, which is a precisely measured 6-8mm diameter threaded steel bar. The middle of the reinforcing bar is fixed to a clamp, and then the bar is bent using a wrench. The wrench has a shaft hole and a second roller at its front end, with the shaft hole fitted onto a rotating shaft. The wrench is then moved along the bending direction, with the first and second rollers contacting the two sides of the reinforcing bar in a staggered position. After one bending, a second bending is performed, requiring a total of four bending processes. Finally, the ends of the reinforcing bar overlap, and the gap at the overlapping ends is fixed by welding. The final disassembly forms a nearly integral ring-shaped reinforcing bar. Compared to traditional ring-shaped reinforcing bars, this invention saves materials and provides greater structural stability. Attached Figure Description

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figure 1 and Figure 2 As shown: A ring-shaped rib processing and forming equipment includes a base 2, a square mold 1 fixed on the upper side of the base 2, the mold 1 is a plate structure, and a first roller 11 is installed at the corresponding corner position. A rotating shaft 21 is installed on the base 2 at the corresponding position of the first roller 11. The rotating shaft is a column structure, with the lower end vertically fixed to the base and the upper end being a free end.

[0022] A clamp 3 is fixed on the upper side of the base 2 corresponding to the side of the mold, which is used to clamp and fix the steel bar 5;

[0023] It also includes a wrench 4 for bending the reinforcing bar 5. The wrench 4 has a handle 43 at the rear end and shaft holes 42 at the front and rear for connecting the rotating shaft 21 for rotation. A second roller 41 is installed on the wrench 4 near the shaft hole 42.

[0024] This invention uses a mold to shape reinforcing bars, which are precisely measured 6-8mm diameter threaded steel bars. The middle of the reinforcing bar is fixed on a clamp, and then the bar is bent using a wrench. The wrench has a shaft hole and a second roller at its front end, with the shaft hole fitted onto a rotating shaft. The wrench is then moved along the bending direction, with the first and second rollers contacting the two sides of the reinforcing bar in a staggered state. After one bending, a second bending is performed, requiring a total of four bending processes. Finally, the ends of the reinforcing bar are aligned, and the gap at the aligned ends is fixed by welding. The entire assembly is then disassembled to form a nearly integral ring-shaped reinforcing bar. Compared to traditional ring-shaped reinforcing bars, this design saves material and provides greater structural stability.

[0025] like Figure 3As shown: Mold 1 has slots 12 on all four sides. These slots are used to accommodate clamps, and sufficient space is reserved at the joints of the rebar ends for welding. Mold 1 consists of upper and lower mold plates. The lower mold plate is fixed to the base 2, while the upper mold plate is detachable. There is a sandwich layer between the upper and lower mold plates. This sandwich layer is used to accommodate the bent rebar. Because the rebar has reverse stress after bending, it will spring back a certain distance after the wrench force is released. Therefore, when bending the rebar, it is necessary to bend it excessively to compensate for the error caused by the springback. There are support columns 14 between the lower mold plate and the upper mold plate. The support columns 14 have limiting steps, with the lower end fixed to the lower mold plate and the upper end having studs for passing through the upper mold plate and being fixed with nuts. The support columns are multi-point, specifically four, located at the square end positions. The upper mold plate is installed there, limited by the limiting steps, with a sandwich layer reserved, and then fixed with nuts. The first roller can be removed by removing the upper mold plate.

[0026] like Figure 4 As shown: Both the first roller 11 and the second roller 41 have axles and arc-shaped grooves on their surfaces to match the sides of the reinforcing bar 5. The function of the limiting reinforcing bar is to prevent misalignment of the reinforcing bar during bending.

[0027] like Figure 2 As shown: The clamp 3 includes a fixed clamping block 31 and a movable clamping block 32. Both the fixed clamping block 31 and the movable clamping block 32 have side clamping grooves, the side projection of which is arc-shaped. A screw 33 is installed on the back side of the movable clamping block 32. A fixing block 34 is provided on the base 2 corresponding to the position of the screw 33. The fixing block 34 has a threaded sleeve through which the screw 33 passes. The end of the screw 33 is rotatably connected to the movable clamping block 32. The other end of the screw also has a handle. Rotating the screw pushes the movable clamping block to move towards the fixed clamping block, thus completing the clamping and fixing of the reinforcing bar.

[0028] The movable clamping block 32 has limiting rods 35 on both sides of the screw 33, and the fixed block 34 has limiting holes for the limiting rods 35 to pass through.

[0029] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
