Description

Technical Field

[0001] This utility model relates to a perforating machine, specifically to an improved multi-roller high-power perforating machine. Background Technology

[0002] With the continuous development of the steel pipe market and market demand, the diameter of seamless steel pipes is gradually increasing. Some industries even require steel pipes with a diameter of 1 meter. The increase in the diameter of steel pipes means that the power of the piercing machine increases and the working conditions become more severe.

[0003] The reducer used in piercing mills is a key piece of equipment in the steel pipe industry. When the working conditions of the piercing mill are harsh, the reducer not only needs to run continuously for a long time, but also needs to have high impact strength, withstand frequent impacts, and operate stably.

[0004] like Figure 1 As shown, the existing punching machine's reducer has a three-roller structure. The input shaft is connected to a full-power motor, and the power is transmitted to the first output shaft through a two-stage transmission. Then, it is transmitted to the second output shaft through the first idler wheel, and then to the third output shaft through the second idler wheel, ultimately realizing the operation of the reducer.

[0005] Of course, the cylinder mounting holes designed on the reducer housing must not interfere with the No. 1 output shaft, No. 2 output shaft, No. 3 output shaft, No. 1 idler wheel, and No. 2 idler wheel.

[0006] When the drilling machine has low power, a three-roll reducer can maximize its functionality, and the reducer's length and height are relatively small, saving on processing and transportation costs. However, when the drilling machine has high power, the reducer also needs to have higher power, resulting in a significantly larger length and height for the three-roll reducer to meet the machine's functions. This reduces the reducer's operational stability and increases processing and transportation costs. Furthermore, interference may occur between the first, second, and third output shafts and the cylinder mounting holes, failing to meet design requirements.

[0007] Therefore, existing punching machines can no longer meet the requirements of actual working conditions. The punching machines that can meet the requirements are too bulky, causing production costs to rise sharply, and some are even unable to produce. Summary of the Invention

[0008] The purpose of this utility model is to provide an improved multi-roll high-power piercing machine, which optimizes and disassembles the existing piercing machine structure, not only achieving stable operation of the high-power piercing machine, but also saving certain processing costs and meeting market demands.

[0009] The technical solution of this utility model is: the improved multi-roll high-power piercing machine includes a high-power reducer, characterized in that: the high-power reducer is composed of three low-power reducers, the power of which is 1 / 3 of the full power, and the three low-power reducers are integrated into one through an output coupling to realize the method of splitting and recombining the flow.

[0010] This utility model has the following advantages:

[0011] 1. The high-power reducer adapted to high-power punching machines achieves its function through a splitting and recombining method, simplifying the process and making the structure more stable.

[0012] 2. The power of a small-power reducer is 1 / 3 of its full power, and its weight is reduced by 20%-30%, saving on the design and processing costs of the reducer.

[0013] 3. The three-roll split structure has certain advantages for high-power piercing machines with larger piercing diameters. Its power range can reach 4000KW-8000KW, and the maximum piercing diameter can reach 1020mm.

[0014] 4. The high-power reducer adopts a split roller design and is applied to a high-power piercing machine, which solves the problem of interference of the output roller of the existing reducer and can meet the requirements of smooth operation of the reducer.

[0015] 5. The low-power reducer has a multi-stage herringbone gear structure, which improves the stability of the housing and the strength of the gears.

[0016] 6. The split reducer design is reasonable, simple in structure, smaller in size, runs smoothly, and is easy to maintain and repair later. Attached Figure Description
