Description

Improved multi-roller high-power perforating machine Technical Field The utility model relates to a puncher, in particular to an improved multi-roller high-power puncher. Background With the continuous development of the steel pipe market and the market demand, the diameter of the seamless steel pipe is gradually increased, and some industries even need a steel pipe diameter of 1 meter, and the increased diameter of the steel pipe means that the power of the perforating machine is increased, and the working condition is worse. The speed reducer applied to the puncher is main equipment in the steel pipe industry, and when the working condition of the puncher is severe, the speed reducer is required to run continuously for a long time, the impact strength is high, the impact resistance is frequent, and meanwhile, the operation is required to be stable. As shown in fig. 1, the speed reducer of the existing puncher has a three-roller structure, an input shaft is connected with a full-power motor, the input shaft is transmitted to a first output shaft through secondary transmission, the input shaft is transmitted to a second output shaft through a first idler pulley, the input shaft is transmitted to a third output shaft through a second idler pulley, and finally the operation of the speed reducer is realized. Of course, the cylinder mounting hole designed on the reducer housing must not interfere with the first output shaft, the second output shaft, the third output shaft, the first idler pulley and the second idler pulley. Under the condition of small power of the puncher, the function of the puncher can be maximally realized by the speed reducer with the three-roller structure, the length of the speed reducer and the height of the speed reducer are relatively smaller, and certain processing and transportation cost is saved. However, under the high-power condition of the perforating machine, the speed reducer also has higher power, so that the length of the speed reducer with a three-roller structure capable of meeting the function of the perforating machine is correspondingly changed to be quite large with the height of the speed reducer, on one hand, the running stability of the speed reducer is reduced, the processing cost and the transportation cost are increased, and on the other hand, the first output shaft, the second output shaft, the third output shaft and the cylinder mounting hole can interfere, and the design requirement cannot be met. Therefore, the existing puncher cannot meet the actual working condition requirements, the puncher capable of meeting the requirements is too heavy to manufacture, the production cost rises directly, and some punchers cannot be produced. Disclosure of Invention The utility model aims to provide an improved multi-roller high-power perforating machine, which is optimized and disassembled on the structure of the existing perforating machine, so that the stable operation of the high-power perforating machine is realized, certain processing cost is saved, and the market demand is met. The improved multi-roller high-power perforating machine comprises high-power speed reducers and is characterized in that the high-power speed reducers consist of three low-power speed reducers, the power of the high-power speed reducers is 1/3 of the full power, and the three low-power speed reducers are integrated through an output coupling to realize a split-flow and combined mode. The utility model has the following advantages: 1. The high-power speed reducer of the high-power perforating machine is realized in a split flow and combined flow mode, so that the structure is simplified and stable. 2. The power of the low-power speed reducer is 1/3 of the full power, the weight is reduced by 20% -30%, and the design cost and the processing cost of the speed reducer are saved. 3. The three-roller split structure is used, so that the three-roller split structure has certain advantages for a high-power perforating machine with larger perforation diameter, the power range of the three-roller split structure can reach 4000KW-8000KW, and the perforation diameter can reach 1020mm at maximum. 4. The high-power speed reducer adopts a split roller design and is applied to a high-power perforating machine, so that the problem of interference of output rollers of the existing speed reducer is solved, and the stable operation requirement of the speed reducer can be met. 5. The low-power speed reducer is of a multi-stage herringbone tooth structure, and the stability of the box body and the strength of the gears are improved. 6. The split speed reducer mode is reasonable in design, simple in structure, small in overall dimension, stable in operation and convenient for later maintenance.
