[0038] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0039] Combine Figures 2 to 6 As shown, the present invention provides a reinforcing ring bending device, which includes a working platform 1, a bending mechanism 2 and an electric pump hydraulic jack 3.

[0040] The work platform 1 includes a work platform body and a backrest 101 disposed on the upper surface of the work platform body.

[0041] The working platform body includes a platform main board 102 , a platform long board 103 , a first platform leg 104 , a second platform leg 105 and a fixed support 106 .

[0042] The platform mainboard 102 is configured as a rectangular plate.

[0043] Two platform long plates 103 are provided and symmetrically welded (butt-welded) on two opposite sides of the platform main plate 102 .

[0044] The platform main board 102 and the platform long strip board 103 are used to place the bending mechanism 2 and flat steel.

[0045] Four first platform legs 104 are provided and are welded (corner welded) to the four corners of the lower surface of the platform mainboard 102 .

[0046] There are multiple second platform legs 105, all welded (corner welded) to the lower surface of the platform main board 102, and evenly distributed between the two first platform legs 104 along the length of the platform main board 102.

[0047] The fixed support 106 is used to connect and fix the first platform leg 104 and the second platform leg 105 .

[0048] The connection combination between the first platform leg 104, the second platform leg 105 and the fixed support 106 ensures the stability of the working platform 1 during the flat steel bending operation.

[0049] The bending mechanism 2 includes a main plate 201 , a pressing die 202 , a first fixing plate 203 and an anti-sway structure.

[0050] The anti-sway structure includes a second fixing plate 204 , a first diagonal support plate 205 and a second diagonal support plate 206 .

[0051] The first fixing plate 203 is welded to the upper surface of the platform mainboard 102 .

[0052] The main board 201 is connected to the first fixing plate 203 near the middle by a first bolt pair 207, and the main board can rotate around the first bolt pair 207. The first bolt pair 207 serves as a fulcrum to ensure that the main board 201 can rotate up and down to form a lever structure.

[0053] The pressing die 202 is connected to the inner end of the main plate 201 via a second bolt pair 208 and is disposed toward the backrest 101 .

[0054] The die 202 serves as a bending template for the reinforcement ring to ensure that the arc radius of the reinforcement ring meets the requirements after bending. The second bolt pair 208 is used to fix the die 202. By removing the second bolt pair 208 and replacing the die 202 with a different arc radius, reinforcement rings of different specifications can be bent.

[0055] The outer end of the main board 201 extends to the outside of the platform main board 102 and cooperates with the electric pump hydraulic jack 3.

[0056] Two second fixing plates 204 are provided, both of which are welded to the upper surface of the platform main board 102 and symmetrically located on both sides of the outer end of the main board 201 .

[0057] The upper end of the first diagonal support plate 205 is connected to the upper ends of the two second fixing plates 204 . The lower end of the first diagonal support plate 205 is formed with a notch 211 that matches the outer end of the main plate 201 .

[0058] One end of the second diagonal support plate 206 is connected to the upper end of the first diagonal support plate 205 and the upper ends of the two second fixing plates 204 , respectively. The other end of the second diagonal support plate 206 is arranged toward the inner end of the main plate 201 .

[0059] An adjusting bolt 209 is provided on the second diagonal support plate 206 , and the adjusting bolt 209 can adjust the rotation range of the main board 201 .

[0060] A reinforcing block 210 is further provided on the top of the main board 201 , and the reinforcing block 210 serves to strengthen the main board 201 and prevent the main board 201 from being deformed due to long-term bending operations.

[0061] The first fixing plate 203, the second fixing plate 204 and the first diagonal support plate 205 are used to fix the main plate 201 to prevent the main plate 201 from shaking when the flat steel is bent.

[0062] An assembly gap of 3 mm or more is left between the inner side of the notch 211 and the outer side of the outer end of the main board 201 .

[0063] The bending mechanism 2 is welded to the working platform 1. Under the action of the electric pump hydraulic jack 3, the main board 201 can rotate up and down. Using the lever principle, the main board 201 applies external force to the flat steel, thereby bending the flat steel.

[0064] The electric pump hydraulic jack 3 is located below the working platform body 1 .

[0065] There are four backers 101 , two of which form a group and are symmetrically welded to the upper surface of the platform mainboard 102 . A processing hole 107 is opened on the platform mainboard 102 between the two groups of backers 101 , and the processing hole 107 corresponds to the die 202 .

[0066] After the bending mechanism 2 is placed on the work platform 1, the backrest 101 is positioned and welded on the work platform 1 with the plane of the die 202 as the reference to ensure that the end of the backrest 101 is perpendicular to the die 202. During the flat steel bending operation, the backrest 101 can prevent the flat steel from sliding and dislocating.

[0067] The use process of the reinforcing ring bending device of the utility model is as follows:

[0068] S1, making the working platform 1 and the bending mechanism 2 into components respectively, and then welding the bending mechanism 2 to the working platform 1;

[0069] S2, assembling the electric pump hydraulic jack 3 and the bending mechanism 2 into an assembly using a bolt pair;

[0070] S3, electric pump hydraulic jack 3 connected to the power supply;

[0071] S4, placing the flat steel on the work platform 1, marking the arc position of the flat steel, and marking the bending area accordingly;

[0072] S5, turning on the switch button of the electric pump hydraulic jack 3;

[0073] S6: Align the area of ​​the flat steel to be bent with the die 202 of the bending mechanism 2, rotate the regulating valve of the electric pump hydraulic jack 3, so that the piston of the electric pump hydraulic jack 3 moves upward to contact the outer end of the main plate 201, and the die 202 moves downward, completing the single arc bending of the reinforcement ring;

[0074] S7, turn the regulating valve of the electric pump hydraulic jack 3 to restore the piston of the electric pump hydraulic jack 3 to the initial state, remove the flat steel, check that it is correct, and repeat step S6.
