Said rectangular tube (301), rectangular tube (101) and rectangular tube (501) vertically all are equipped with shrouding in the side.
Another goal of the invention of the utility model is achieved in that
A kind of cutting machine that uses the rectangular tube drive beam comprises the active end carriage conjunction (18) and the motor that are made up of rectangular tube (301), and said motor is connected on the active end carriage conjunction (18); On rectangular tube (101,501) the diapire outer surface fixed head eccentric shaft and clamp shaft are housed, scraper plate is positioned at the fixed head outboard end; Roller shaft and roller all are equipped with in rectangular tube (201,401) inboard; The roller roller shaft interior with being fixed in rectangular tube (201,401) cooperates; Reducer pedestal (11) fixes on rectangular tube (401) sidewall through hinges fixing, and motor gear (9) passes reducer pedestal (11) from top to bottom; Said rectangular tube also is equipped with elastic supporting member on (301), and said reducer pedestal (11) is provided with the breach that engages with elastic supporting member.
The described rectangular tube drive beam of the utility model has following advantage:
1, the rectangular tube drive beam of the utility model is welded by 5 sections GB quarter bends, and is simple in structure, has only a spot of saw processing, welding job amount.Lack because weld seam is few, need not stress removing operations such as tempering, practice thrift cost of manufacture in a large number.
2, the transverse property of quarter bend itself has guaranteed the high rigidity of section girder construction to have satisfied the cutting technique requirement well.
3, the hinge type motor cabinet matches with spring connecting structure, when satisfying the cutting machine high-speed motion, keeps flexible engagement between rack-and-pinion, has prolonged part life.
