Description
Technical field
The invention belongs to the seamless steel pipe production technical field, be specifically related to a kind of milling train blank pushing machine structure of seamless steel pipe production.
Background technology
At present; More the blank pushing machine structure of producing slitless tube mill both at home and abroad adopts the hydraulic cylinder drive to cut somebody's hair and realizes pushing away solid billet or hollow ingot; This mechanism pushes away the restriction that the base stroke receives hydraulic cylinder travel, portable station pattern; Particularly the milling train portable station uses under the situation of plug, in actual production, needs a large amount of tool and moulds.And if in design process charge length change too greatly, vary in diameter greatly, also to consider to push away the interference problem of base hydraulic cylinder and graphite lubrication case, restraint device, and possibly cause the length increase of milling train foreground, the use cost of increase plug.The position difficulty that on-the-spot adjustment is cut somebody's hair under the situation that particularly big unit production specification is many, batch is few, has strengthened labour intensity especially, and productivity ratio is also very low.
Summary of the invention
The blank pushing machine structure that the invention provides a kind of milling train has solved prior art and has adopted hydraulic cylinder to drive to cut somebody's hair and realize pushing away base and exist and push away that the base stroke receives the restriction of hydraulic cylinder travel, portable station pattern and milling train foreground length increases and the use cost of plug is high, improves the technical problem of unit productivity ratio.
The present invention overcomes the above problems through following scheme:
A kind of blank pushing machine structure of milling train comprises the foreground base, the travelling carriage that on the base of foreground, is provided with; One end of travelling carriage is fixed together with cutting somebody's hair; Bearing pin and rear pin shaft before on the side of the other end of travelling carriage, being provided with to the horizontal interval, one side of base is respectively arranged with front-end bearing pedestal device and rear bearing block device on the foreground, and the front-end bearing pedestal device is provided with preceding sprocket wheel; The rear bearing block device is provided with the back sprocket wheel; Before sprocket wheel axle successively through first shaft coupling, reductor, brake, second shaft coupling with to be arranged on the output shaft of the motor on the motor bearing mechanically coupled together, sprocket wheel and afterwards be provided with chain between the sprocket wheel before described, and the head end of this chain and preceding bearing pin are fixed together; The end and the rear pin shaft of this chain are fixed together; Form the chain transmission loop of a sealing, travelling carriage is provided with a row travelling carriage bolt hole of above-below direction, on the caudal peduncle of cutting somebody's hair, also is provided with one of above-below direction and is listed as the bolt hole of cutting somebody's hair; The different travelling carriage bolt holes and the combination back, bolt hole of cutting somebody's hair are fixed with set bolt, thus the adjustment up and down that realization is cut somebody's hair.
Described reductor is provided with the encoder that the position of cutting somebody's hair is detected.
The present invention has simple in structure, easy operating can satisfy the requirement of different size steel pipe, the equipment investment of having saved early stage, and the plug use cost of saving the later stage.The portable station that can satisfy different types uses.

Specific embodiment
A kind of blank pushing machine structure of milling train; Comprise foreground base 1, the travelling carriage 6 that on foreground base 1, is provided with, an end of travelling carriage 67 are fixed together with cutting somebody's hair; Bearing pin 17 and rear pin shaft 18 before on the side of the other end of travelling carriage 6, being provided with to the horizontal interval; One side of base 1 is respectively arranged with front-end bearing pedestal device 3 and rear bearing block device 21 on the foreground, and front-end bearing pedestal device 3 is provided with preceding sprocket wheel 2, and rear bearing block device 21 is provided with back sprocket wheel 20; Before the axle 4 of sprocket wheel 2 mechanically coupled together through first shaft coupling 10, reductor 11, brake 12, second shaft coupling 13 successively with the output shaft that is arranged on the motor 14 on the motor bearing 16; Sprocket wheel 2 and back are provided with chain 5 between the sprocket wheel 20 before described, and the head end of this chain 5 and preceding bearing pin 17 be fixed together, and the end of this chain 5 and rear pin shaft 18 are fixed together; Form the chain transmission loop of a sealing; Travelling carriage 6 is provided with a row travelling carriage bolt hole 8 of above-below direction, and row that on 7 the caudal peduncle of cutting somebody's hair, also the are provided with above-below direction bolt hole 19 of cutting somebody's hair is fixed the different travelling carriage bolt hole 8 and the 19 combination backs, bolt hole of cutting somebody's hair with set bolt; Thereby realize cutting somebody's hair 7 adjustment up and down, realize the base that pushes away the pipe 9 of different size.Described reductor 11 is provided with the encoder 15 that 7 positions of cutting somebody's hair are detected.
Pipe 9 is admitted to the foreground blow tank, and after plug penetrated pipe and puts in place, motor 14 started; Through second shaft coupling 13, reductor 11, first shaft coupling 10 power is passed on the axle 4 that sprocket wheel 2 is housed, sprocket wheel 2 rotates before driving, and preceding sprocket wheel 2 drives through chain 5 and 7 the travelling carriage 6 of cutting somebody's hair is housed to front slide; After milling train is nipped smoothly; Brake 12 braking, sprocket wheel 2 stops operating motor 14 counter-rotatings before making through second shaft coupling 13, reductor 11, first shaft coupling 10 etc.; Cut somebody's hair and 7 get back to initial position, wait for next time and push away base.During adjustment steel pipe specification, operating principle is fixed on the encoder 15 of the reductor 11 output shaft other ends with pushing away base, through feedback information, and the brake braking motor, accurately adjustment pushes away the base initial position.
