Description

Technical Field

[0001] The utility model relates to the technical field of flange processing, in particular to a flange trimming die. Background Technique

[0002] A flange, also known as a flange plate or a boss, is a part used for connecting shafts to each other. It is used for connecting pipe ends and is also used for flanges at the inlets and outlets of equipment for connecting two pieces of equipment. It is a widely used component. Forging is one of the common production methods of flanges. After the initial forging, a trimming device is required to remove the burrs on the surface of the flange.

[0003] The existing flange trimming die has the following drawbacks in the use process: When installing the flange for trimming processing, it is necessary to adjust the position of the cutting tool or the position of the flange after completing one-sided trimming, so that the cutting tool can remove the burrs at different positions on the outer circumference of the flange part, resulting in low processing efficiency. Therefore, we propose a flange trimming die. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a flange trimming die. By arranging a positioning mechanism on the surface of the lower die base, the die can be quickly fixed and a rotatable structure is adopted to complete the trimming process of the outer circumference of the flange, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A flange trimming die includes a lower die base and a positioning mechanism. The positioning mechanism is arranged on the top of the lower die base. The positioning mechanism includes an upper die base, a turntable, a support ring, an insertion post, a motor, a bearing, a sleeve, a spring, a connecting rod, and a pressing ring. The upper die base is provided with a matching upper die base on the top. The lower die base is internally connected with a support ring through a turntable, and an insertion post inserted into the central hole of the flange is installed at the center of the top of the support ring. A motor is installed at the bottom of the lower die base, and the power end of the motor is connected to the bottom of the support ring. A bearing is installed at the bottom of the upper die base and is movably connected with a sleeve through the bearing. A connecting rod is movably connected with the sleeve through a spring inside the sleeve, and the bottom of the connecting rod is fixedly connected with a pressing ring pressing on the top of the flange.

[0007] Further, it further includes a trimming mechanism. A trimming mechanism is provided at the bottom of the upper die base. The trimming mechanism includes a chute, a slider, a mounting seat, and an arc-shaped cutting tool. A chute is horizontally opened on one side of the bottom of the upper die base, and the slider is slidably connected through the chute. A mounting seat is provided at the bottom of the slider, and an arc-shaped cutting tool is mounted at the bottom of the mounting seat. An arc-shaped cutting tool is mounted at the bottom of the upper die base through the slider and the mounting seat. The arc-shaped cutting tool can be replaced according to different specifications of flange parts. At the same time, for flange parts of different specifications, their outer peripheral positions are different after positioning. The screw can be screwed along the screw hole, and the slider is driven by the screw to move along the chute, adjusting the positions of the mounting seat and the arc-shaped cutting tool so that the processing position of the arc-shaped cutting tool is exactly aligned with the outer peripheral side of the flange part.

[0008] Further, limiting cylinders are mounted on both sides of the top of the lower die base, and limiting rods inserted into the limiting cylinders are mounted on both sides of the bottom of the upper die base. The cooperation of the limiting cylinder and the limiting rod plays a role in limiting the displacement of the upper die base.

[0009] Further, limiting grooves are opened on both sides of the inner wall of the sleeve, and a clamping block inserted into the limiting groove is fixedly connected to the outer wall of the connecting rod. The cooperation of the limiting groove and the clamping block enables the rotation of the rotating ring to drive the sleeve to rotate.

[0010] Further, a screw hole is opened on the surface of the upper die base near the chute, and a screw is threadedly connected through the screw hole. A connecting ring located inside the slider is mounted at the end of the screw. When the screw is screwed along the screw hole, the horizontal displacement of the slider can be driven through the connecting ring to adjust the position of the arc-shaped cutting tool.

[0011] Compared with the prior art, the utility model has the following beneficial effects: A supporting ring is mounted inside the lower die base through a turntable. The top of the supporting ring is used to support the flange part to be processed. At the same time, the inserting post is inserted into the central hole of the flange. After the flange is installed in place, the upper die base moves downward under the action of the external stamping assembly. The pressing ring first contacts the top of the flange and cooperates with the supporting ring to fix the position of the flange. Subsequently, the upper die base continues to move downward, the spring is compressed until the arc-shaped cutting tool completes the trimming process on one side of the flange. After trimming, the upper die base moves upward while the pressing ring keeps fixing the flange. At this time, when the motor operates, the supporting ring can be rotated electrically to adjust the angle of the flange, making different directions of the outer periphery of the flange aligned with the position of the cutting tool, facilitating the comprehensive trimming of the outer periphery of the flange and improving the processing efficiency. An arc-shaped cutting tool is mounted at the bottom of the upper die base through the slider and the mounting seat. The arc-shaped cutting tool can be replaced according to different specifications of flange parts. At the same time, for flange parts of different specifications, their outer peripheral positions are different after positioning. The screw can be screwed along the screw hole, and the slider is driven by the screw to move along the chute, adjusting the positions of the mounting seat and the arc-shaped cutting tool so that the processing position of the arc-shaped cutting tool is exactly aligned with the outer peripheral side of the flange part.
