[0002] The flange processing tooling is a device that assists in positioning the flange during flange processing to facilitate flange processing. Generally, when using the flange processing tooling to punch the flange, a pair of clamps are usually used to fix the flange close to each other, which causes the flange to move toward the direction without the clamps during processing, thereby affecting the flange processing.

[0003] For example, a Chinese utility model, with publication number CN216463159U, discloses a flange processing tool, including a box body, the outer wall of the box body is fixedly connected to a first motor, the output shaft of the first motor is fixedly connected to a screw, the outer wall of the screw is movably connected to a movable block, the bottom of the movable block is fixedly connected to an electric push rod, the telescopic end of the electric push rod is fixedly connected to a fixed plate, the end of the fixed plate away from the electric push rod is fixedly connected to a first slide body, the interior of the first slide body is movably connected to a first processing device, the outer wall of the fixed plate is fixedly connected to a hydraulic push rod, the telescopic end of the hydraulic push rod is fixedly connected to a connector, and the end of the fixed plate away from the electric push rod is fixedly connected to a second processing device.

[0004] This product has the advantages of conveniently processing two flanges at the same time and improving processing efficiency. However, this product only uses nuts to limit the flanges. The flanges are easily deflected during the processing, affecting the processing accuracy. Therefore, it is necessary to further improve this product. Summary of the Invention

[0005] The utility model aims to provide a flange processing tool to solve the problem in the prior art that the flange is easily deflected during the processing, thereby affecting the processing accuracy.

[0006] The purpose of the utility model is achieved as follows: a flange processing tool, including a bottom plate, a base plate is installed on the bottom plate, a plurality of through holes are opened on the base plate, a circular sleeve is detachably installed on the inner circumference of the through hole, a limiting ring is extended to the outer circumference of the circular sleeve, a storage ring is provided on the inner circumference of the circular sleeve, a processing position for placing a flange is provided on the storage ring, a pressing piece for abutting against the upper end face of the flange is provided on the upper end of the flange, a plurality of cylinders are installed on the bottom plate, the output end of the cylinder is connected to a cylinder, one end of the cylinder passes through the flange and is threadedly connected to a nut after the pressing piece.

[0007] Preferably, a limiting groove 1 is provided on the outer periphery of the through hole 1, a limiting groove 2 communicating with the limiting groove 1 is provided on the circular sleeve, a limiting block is formed at one end of the pressing sheet, and the limiting block is clamped in the limiting groove 1 and the limiting groove 2.

[0012] Preferably, a side panel is mounted on the bottom panel, and the base plate is mounted on the upper end of the side panel.

[0013] Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

[0014] 1. The utility model sets a circular sleeve. After the flange is placed in the circular sleeve, a pressing piece is set on the upper end of the flange. The cylinder is used to generate pressure to fix the flange between the pressing piece and the circular sleeve. Compared with the prior art in which the flange body is pressed against the top of the support plate by a nut, the utility model increases the contact area by using a pressing piece and increases the pressure by using a cylinder, which can effectively prevent the flange from shifting during the processing.

[0015] 2. The round sleeve of the utility model is fixed on the base plate through the threaded hole, which is convenient for disassembly and can be replaced at any time. When processing flanges of different sizes, the round sleeve of the corresponding size is selected for installation without replacing the tooling, thereby improving the processing efficiency.

DETAILED DESCRIPTION

[0022] The specific implementation of the present invention is further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown, a flange processing tool comprises a base plate 1, a base plate 2 is installed on the base plate 1, and a plurality of through holes 3 are opened on the base plate 2. A circular sleeve 4 is detachably installed on the inner circumference of the through hole 3, and a limiting ring 5 is extended to the outer circumference of the circular sleeve 4. A placement ring 6 is provided on the inner circumference of the circular sleeve 4. A processing position for placing a flange 8 is provided on the placement ring 6, and a pressing piece 9 for resting against the upper end face of the flange 8 is provided on the upper end of the flange 8. Several cylinders 7 are installed on the base plate 1, and the output end of the cylinder 7 is connected to a cylinder 10. One end of the cylinder 10 passes through the flange 8 and the pressing piece 9 and is threadedly connected to a nut 11. This product is provided with a circular sleeve 4. After the flange 8 is placed in the circular sleeve 4, a pressing piece 9 is provided at the upper end of the flange 8. The cylinder 7 is used to generate pressure to fix the flange 8 between the pressing piece 9 and the circular sleeve 4. The pressing piece 9 is used to increase the contact area, and the cylinder 7 is used to increase the pressure, which can effectively prevent the flange 8 from shifting during the processing.

[0024] like Figure 1 and Figure 2 As shown, the outer periphery of the through hole 13 is provided with a limiting groove 12, and the circular sleeve 4 is provided with a limiting groove 2 13 communicating with the limiting groove 12. Figure 4 A limiting block 14 is formed at one end of the pressing piece 9, and the limiting block 14 is clamped in the limiting groove 12 and the limiting groove 2 13. By opening the limiting groove 12 and the limiting groove 2 13, the limiting block 14 can be clamped and fixed, thereby limiting the movement of the pressing piece 9.

[0025] Further, combined Figure 2 One end of the pressing sheet 9 is provided with a through slot 15 for the processing device to pass through. The processing device processes the flange 8 through the through slot 15, effectively avoiding interference from the pressing sheet 9.

[0026] Combine Figure 1 and Figure 2 The outer diameter of the pressing piece 9 is smaller than the inner diameter of the circular sleeve 4, which can ensure that the pressing piece 9 is tightly attached to the flange 8. At this time, there is a processing groove between the pressing piece 9 and the circular sleeve 4, and the processing device can process the flange 8 through the processing groove between the pressing piece 9 and the circular sleeve 4.

[0027] Look specifically Figure 1 and Figure 4 The lower end of the nut 11 abuts against the pressing plate 9, and the pressure of the cylinder 7 is transmitted to the pressing plate 9 through the nut 11, thereby fixing the flange 8 in the processing position.

[0028] To facilitate the replacement of the round sleeve 4, see Figure 1 and Figure 2 The limiting ring 5 is provided with a plurality of through holes 16, and the upper end surface of the substrate 2 is provided with threaded holes 18 corresponding to the through holes 16. The circular sleeve 4 is fixed to the substrate 2 by threaded connection, so that the circular sleeve 4 is easy to disassemble and replace.

[0029] Combine Figure 1 and Figure 4 The bottom plate 1 is provided with a side plate 17 , and the upper end of the side plate 17 is provided with the base plate 2 , which effectively increases the stability of the device and prevents the device from shifting during processing.
