[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] A flange trimming mold includes a fixed seat 1 and a movable seat 2. The top of the fixed seat 1 is fixedly connected to a supporting mechanism 3 for supporting the flange. The supporting mechanism 3 includes a fixed sleeve 301. A supporting ring 302 is installed on the top of the fixed sleeve 301. A trimming mold 4 is installed at the bottom of the movable seat 2 and above the supporting mechanism 3. The trimming mold 4 is used to move downward to trim the flange on the supporting mechanism 3.

[0025] A lifting cylinder 5 is installed on the top of the fixed seat 1, and the top of the lifting cylinder 5 is fixedly connected to a lifting plate 6, and the top of the lifting plate 6 is fixedly connected to a side limiting block 7. The bottom of the movable seat 2 is fixedly connected to a connecting sleeve 8, and the top of the fixed seat 1 is fixedly connected to a lifting cylinder 9, and the top of the lifting cylinder 9 is fixedly connected to the top of the inner wall of the connecting sleeve 8.

[0026] like Figure 3 and Figure 4 The bottom of the load-bearing ring 302 is fixedly connected to the limiting ring, and the surface of the limiting ring fits against the inner surface of the fixing sleeve 301, which limits the load-bearing ring 302 and prevents horizontal movement of the limiting ring 302 and the fixing sleeve 301. The lifting cylinder 5 and the lifting cylinder 9 are both existing technologies and will not be described in detail here.

[0027] like Figure 1 and Figure 2 There is a cutting mechanism at the bottom of the trimming die 4, which can be moved downward to trim the flange below. The connecting sleeve 8 is mounted on the surface of the telescopic end of the lifting cylinder 9, so that while ensuring the telescopic movement of the lifting cylinder 9, the space occupied by the entire mold is reduced.

[0028] A rectangular limiting block 10 is fixedly connected to the top of the fixed seat 1, and a vertical guide rod 11 is fixedly connected to the bottom of the movable seat 2. The vertical guide rod 11 and the rectangular limiting block 10 are slidably connected.

[0029] like Figure 1 The rectangular limiting block 10 can limit the maximum distance that the movable seat 2 descends. The sliding connection between the vertical guide rod 11 and the rectangular limiting block 10 can ensure that the movable seat 2 can move up and down in the vertical direction.

[0030] A supporting base 12 is fixedly mounted on the bottom of the fixing seat 1 , and two concave bottom cavities 13 are formed on the bottom of the supporting base 12 .

[0031] like Figure 1 and Figure 2 The bottom of the supporting base 12 has an opening to facilitate the fixing of the supporting base 2 to the external device.

[0032] The fixing sleeve 301 is fixed to the top of the fixing seat 1, and the guide plate 14 and the spring 15 are fixedly connected inside the fixing sleeve 301. The positioning kit 16 is slidably connected to the guide plate 14. One end of the spring 15 is fixedly connected to the positioning kit 16, and the bottom of the load-bearing ring 302 is fixedly connected to an L-shaped positioning plate 17 used in conjunction with the positioning kit 16.

[0033] like Figure 1 The positioning kit 16 is provided with a horizontal U-shaped end portion, and the spring 15 pushes the positioning kit 16 toward the L-shaped positioning plate 17, so that one end of the L-shaped positioning plate 17 is stuck in the positioning kit 16, and the guide plate 14 passes through the positioning kit 16, so that the positioning kit 16 can only move horizontally.

[0034] The interior of the fixing sleeve 301 is fixedly connected to the adjusting sleeve 18 , and the adjusting sleeve 18 is provided with a piston push rod 19 . One end of the piston push rod 19 extends to the outside of the adjusting sleeve 18 and is fixedly connected to the positioning sleeve 16 .

[0035] like Figure 3 and Figure 4 The piston part of the piston push rod 19 is located inside the adjustment sleeve 18, which can ensure that the air flow between the two sides of the piston inside the adjustment sleeve 18 does not flow.

[0036] An air pump 20 is fixedly installed at the bottom of the supporting base 12, and a connecting air pipe 21 is fixedly connected to the air pump 20. A diversion air pipe 22 is fixedly connected to the bottom of the adjusting sleeve 18. One end of the diversion air pipe 22 passes through the fixed sleeve 301 and the supporting base 12 in sequence and is fixedly connected to the connecting air pipe 21.

[0037] like Figure 2 and Figure 3The connecting air pipe 21 is connected to a plurality of branch air pipes 22 , and a branch air pipe 22 is provided at the bottom of each fixed sleeve 301 , so that the air pump 20 can control the movement of the piston push rods 19 inside the plurality of fixed sleeves 301 through the connecting air pipe 21 and the branch air pipe 22 .

[0038] The working principle of the flange trimming die provided by the utility model is as follows:

[0039] When the flange needs to be trimmed, the flange is placed on the bearing ring 302, and then the lifting cylinder 9 drives the movable seat 2 to move downward, and the movable seat 2 drives the trimming die 4 to move downward to trim the bearing ring 302. At the same time, the lifting cylinder 5 drives the lifting plate 6 to move upward, so that the lifting plate 6 contacts the bottom of the flange, and the side limit block 7 moves to one side of the flange to improve the stability of the flange.

[0040] When flanges of different specifications need to be trimmed, the air pump 20 can be started. The air pump 20 inflates the adjusting sleeve 18 through the connecting air pipe 21 and the branch air pipe 22, so that the piston push rod 19 drives the positioning kit 16 and the L-shaped positioning plate 17 to separate. At this time, the load ring 302 can be moved upward to separate the load ring 302 and the fixing sleeve 301.

[0041] On the contrary, the carrying ring 302 is set above the fixing sleeve 301, and the L-shaped positioning plate 17 is moved down into the fixing sleeve 301. The air pump can deflate the adjusting sleeve 18 through the connecting air pipe 21 and the diversion air pipe 22. Under the action of negative pressure and spring 15, the positioning kit 16 is driven to move toward the L-shaped positioning plate 17, so that the L-shaped positioning plate 17 is stuck into the inner side of the positioning kit 16, and the carrying ring 302 is positioned at the top of the fixing sleeve 301.

[0042] Compared with the related art, the flange trimming die provided by the present invention has the following beneficial effects:

[0043] The utility model provides a bearing mechanism for supporting the flange, and is provided with a detachable fixing sleeve 301 and a bearing ring 302. By using the air pump 20 to inflate and deflate, the positioning kit 16 and the L-shaped positioning plate 17 can be directly clamped and separated, which is convenient for installing and disassembling the bearing ring 302. Different bearing rings 302 can be quickly replaced to provide bearing for the flange according to the positioning requirements of flanges of different specifications. The operation is simple and easy to use. In addition, by connecting multiple branch air pipes 22 and connecting air pipes 21, the synchronous positioning and separation between multiple fixing sleeves 301 and bearing rings 302 can be quickly completed.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
