Detailed Description

The structure of this application reinforcing ring bending machine device sees attached figure 2 and attached figure 3, and attached figure 2 is the utility model discloses schematic structure diagram, attached figure 3 is the schematic structure diagram of this device essential element shaping frock.

The reinforcing ring bending machine device is formed by carrying out structural transformation on the basis of the original three-roller plate bending machine. The three-roller plate bending machine comprises a driving wheel 3, a driven wheel 4 and a roller wheel 5, wherein when the plate is bent, the driving wheel 3 rotates, and the driven wheel 4 and the roller wheel 5 are driven to rotate through a steel plate, so that the steel plate is curled into a cylinder body with a required diameter. In general, the roller 5 can be adjusted by moving up and down, so that the curling diameter of the steel plate can be adjusted conveniently. After the plate rolling is finished, one end of the roller 5 can be separated from the fixing device, and the curled barrel is taken down from the three-roller plate rolling machine.

As shown in the attached drawing 2, the utility model discloses reinforcing ring bending machine device installs reinforcing ring shaping frock 6 on running roller 5, and the structure of this shaping frock 6 sees figure 3, include with running roller 5 cooperation installation become take turns 7 and backing plate 9. The inner surface of the forming wheel 7 is provided with a convex key 14 matched with the roller key groove 13, as shown in figure 2. The forming wheel 7 clamps the backing plate 9 and is fixedly arranged through a nut 10 and a lead screw 11. The axial installation position of the forming tool 6 on the roller 5 is fixed by a positioning pin 12, and the positioning mode shown in the attached drawing 4 can also be adopted, namely the non-installation end of the forming tool is positioned by adopting a step shown on the right side, and the installation end of the forming tool can be positioned by adopting a retainer ring 16 shown on the left side. During the use, will shape frock 6 and install, on protruding key 14 and keyway 13 cooperation push running roller 5, can with locating pin 12 location.

Taking a simmer bending T-shaped steel reinforcing ring as an example, the length of the T-shaped steel 8 is determined by calculating the bending diameter of the reinforcing ring, the T-shaped steel 8 with the length enters a groove formed by the forming wheel 7 and the backing plate 9 through the guide wheel 15, the width of the groove corresponds to the thickness of the T-shaped steel 8 reinforcing rib, and the deformation of the T-shaped steel reinforcing rib is limited during the curling. The driving wheel 3 rotates to bring the T-shaped steel 8 into the three-roller plate bending machine, and the T-shaped steel 8 is bent together with the driven wheel 4. After the T-shaped steel 8 is simmered for a circle, the head and the tail are in contact welding, and then the straight edge of the campus welding part is formed. In the bending deformation process, the grooves and the reinforcing ribs are matched to basically realize smooth bending, but in order to ensure the straightness of the T-shaped steel 8, the guide wheels 15 are preferably installed. After bending is finished, the forming tool 6 is detached from the roller 5, the nut 10 and the screw rod 11 are loosened, and the reinforcing ring after bending is taken out. Then the two parts are installed together, the forming tool 6 is assembled with the roller 5 again, and the next round of bending operation is carried out.

For the reinforcing ring made of flat steel, the outer diameter of the forming wheel 7 is adjusted to meet the diameter requirement of the reinforcing ring, and the thickness and the outer diameter of the backing plate 9 are adjusted to adapt to the size of the flat steel. The adjusting mode of the reinforcing ring made of the angle steel is the same as that of the reinforcing ring made of the angle steel.

The bending machine mode of this device, the recess has restricted the deformation of strengthening rib, and bending machine uses tensile deformation to be given first place to, has eliminated wave deformation and fold defect, and the ovality of reinforcing ring has been eliminated in three-roller bending machine for the circularity satisfies the requirement.

In order to improve the production efficiency, the structure shown in the attached figure 4 can be adopted, a plurality of forming wheels 7 and a backing plate 9 are sequentially connected together by nuts 10 and lead screws 11 and then matched with the roller wheels 5, so that a plurality of reinforcing rings can be simmered and bent at one time.

The hot bending device for the reinforcing ring is improved by using the old three-roller plate bending machine, and has the advantages of simple structure and low investment cost. The reinforcing ring is good in bending effect, wave deformation and wrinkle defects are eliminated, the roundness is good, smooth bending of the reinforcing ring is achieved, one-time bending is qualified, and the reinforcing ring is not repaired.
