[0003] Existing reducing pipe processing equipment, such as the Chinese utility model patent CN221185577U (a processing equipment for the straight edge of a large-diameter reducing pipe), represents a class of prior art. Its main structure includes a first clamping plate, a second clamping plate, a first bevel gear, a bolt, a second bevel gear, a third bevel gear, and a fourth bevel gear.

[0004] However, the existing technology and equipment still have the following problems when in use: the existing machines only clamp one end of the reducer, which easily causes the reducer to vibrate during processing, resulting in poor processing quality. In addition, when clamping eccentric reducers, the existing machines are not convenient for positioning and fixing the position of the small end of the reducer, resulting in poor processing quality.

The two rubber pads 53 are respectively installed on the two clamping blocks 52, and the two rubber pads 53 are both located between the two clamping blocks 52.

[0037] First, insert the large end of the reducer into the three-jaw chuck 22. Then, manually adjust the three-jaw chuck 22 to clamp and fix the large end of the reducer. The freely rotating three-jaw chuck 22 allows the reducer to rotate around its own axis during clamping. Next, turn on motor 15. Motor 15 provides power to drive the bidirectional lead screw 12 to rotate, causing slider 16 and slider 2 17 to move closer or further apart, thus adjusting the clamping distance and facilitating the clamping of reducers of different specifications. When the small end of the reducer reaches the rubber pad 53, turn on the gripper cylinder 31. Gripper cylinder 31 provides power to drive the positioning blocks 32 to move closer or further apart. The positioning blocks 32 squeeze the small end of the reducer as they move closer together. The pressure, combined with the three-jaw chuck 22, rotates the small end shaft of the reducer to directly above or below the large end shaft, thereby positioning the small end of the reducer. Then, the motor 3 70 and the gripper cylinder 2 51 are turned on. The motor 3 70 provides power, which is transmitted through the reducer 3 69, the rotating shaft 3 68, the bevel gear 2 71, the sprocket 64 and the chain 65, driving the slider 4 66 to move up and down. The gripper cylinder 2 51 provides power, driving the clamping blocks 52 to move closer or further apart. The clamping blocks 52 move closer together to clamp the small end of the reducer. The rubber pad 53 facilitates clamping the small ends of reducers of different diameters. At this time, the machine simultaneously clamps both ends of the reducer, facilitating the synchronous post-cutting of both ends of the reducer.

[0038] like Figures 1 to 7 As shown, this utility model discloses a synchronous back-cutting device for reducing pipes. During operation, the larger end of the reducing pipe is first inserted into the three-jaw chuck 22. Then, the three-jaw chuck 22 is manually adjusted to clamp and fix the larger end of the reducing pipe. The freely rotating three-jaw chuck 22 allows the reducing pipe to rotate around its own axis during clamping. Next, motor 15 is activated, providing power to drive the bidirectional lead screw 12 to rotate, causing sliders 16 and 17 to move closer or further apart, thus adjusting the clamping distance and facilitating the clamping of reducing pipes of different specifications. When the smaller end of the reducing pipe reaches the rubber pad 53, the clamping cylinder 31 is activated, providing power to drive the positioning blocks 32 to move closer or further apart. The smaller end of the reducer is squeezed by the two jaws moving closer together. With the help of the three-jaw chuck 22, the axis of the smaller end of the reducer rotates to be directly above or below the axis of the larger end, thereby positioning the smaller end of the reducer. Then, the motor 3 70 and the gripper cylinder 2 51 are turned on. The motor 3 70 provides power, which is transmitted through the reducer 3 69, the rotating shaft 3 68, the bevel gear 2 71, the sprocket 64 and the chain 65 to drive the slider 4 66 to move up and down. The gripper cylinder 2 51 provides power to drive the clamping blocks 52 to move closer or further apart. The clamping blocks 52 move closer together to clamp the smaller end of the reducer. The rubber pad 53 facilitates clamping the smaller ends of reducers of different diameters. At this time, the machine simultaneously clamps both ends of the reducer, which facilitates the simultaneous post-cutting of both ends of the reducer.

[0039] The components of this utility model, including the bidirectional lead screw 12, motor 15, three-jaw chuck 22, gripper cylinder 31, two lead screws 41, motor 48, four bevel gears 50, gripper cylinder 51, two rubber pads 53, eight sprockets 64, four chains 65, motor 70, and four bevel gears 71, are commercially available. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative effort from those skilled in the art.

[0040] The main functions achieved by this utility model are as follows: by setting up clamping device 1 02, lifting device 04 and clamping device 2 05, both ends of the reducer are clamped simultaneously, which can prevent the reducer from vibrating during processing and improve the processing quality. Furthermore, by setting up positioning device 03, lifting device 04 and clamping device 2 05, the small end of the eccentric reducer is positioned and clamped and fixed, which improves the processing quality. This solves the existing technical problems that existing machines only clamp one end of the reducer, which easily causes the reducer to vibrate during processing, resulting in poor processing quality. In addition, existing machines are inconvenient to position and fix the small end of the reducer when clamping the eccentric reducer, resulting in poor processing quality.

[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
