Background technology
Traditional steel pipe cutter sweep adopts abrasive cutoff saw to finish cutting work.This cutter sweep exists following shortcoming: 1, Cao Zuo labour intensity is big, and cutting speed is slow, and efficient is low; 2, grinding wheel cost height is fragile, the use cost height; 3, Jia Gong edge of a knife out-of-flatness, quality is not good; 4, Cao Zuo poor stability; 5, environment is existed the pollution of noise and dust.
Summary of the invention
The purpose of this invention is to provide a kind of tool type steel pipe cutting machine, problem such as the labour intensity that traditional steel pipe cutter sweep exists is big, efficient is low to solve, crudy difference and contaminated environment.
Tool type steel pipe cutting machine of the present invention, the technical scheme that realizes above-mentioned purpose is as follows: this tool type steel pipe cutting machine comprises mechanical driving device, mainly is made up of the drive pulley and the drive motors at the bearing that is fixed in tubular knife rest two ends and bearing spider, knife rest middle part; The knife rest part, mainly form by the lathe chuck of tubular knife rest, knife rest one end, the movable cutterhead and the inner hobboing cutter of radially fixing by rotating shaft of cutterhead that are positioned at three grooves of chuck, described cutterhead outer face has one for the groove of placing ball, the cutterhead outer end portion is equipped with back-moving spring, and steel pipe is fixed in knife rest and the chuck hub hole by the holding clamp at two ends; The feed device, but be installed on the steel pipe cutting machine in the horizontal adjusting mode, have an annular inner wall, this inwall middle part vertically is protruding arcuate structure, chuck and cutterhead place annular inner wall, and three balls of three cutterhead outer end settings contact with feed device annular inner wall.
Aforesaid a kind of tool type steel pipe cutting machine, described feed device horizontal adjusting mechanism comprise the horizontal slide rail of movable fixedly feed device, a horizontally disposed tooth bar that is connected with the feed device and a gear that is connected with the hand turning handle that meshes with tooth bar.
Aforesaid a kind of tool type steel pipe cutting machine, the gear in the described feed device horizontal adjusting mechanism are realized driving with stepper motor and are connected.
The present invention compares with traditional pipe cutter sweep, has following good effect:
1, the long service life of cutter is not easy to damage, and use cost is low; With processing maintenance steel pipe scaffold is example, uses 50 steel pipe heads of traditional abrasive wheel cutting machine cutting, uses the every secondary hobboing cutter of pipe cutter sweep of the present invention can cut 500 on equal steel pipe head.The price of every cutoff wheel is 8.00 yuan, and the cost of every secondary special-purpose hob cutter is 15.00 yuan.
2, cutting speed is fast, has improved operating efficiency;
3, can cut the pipe fitting of any diameter, chuck rotation drives the hobboing cutter rotation, the inside feed of hobboing cutter simultaneously, and the worker sees for static, according to the speed of thickness of workpiece debugging mode feed, guarantees that the edge of a knife is neat, has avoided adopting the edge of a knife of the abrasive cutoff saw cutting pipes phenomenon of turning up;
4, basic noiselessness in the hobboing cutter cutting process, free from dust and the phenomenon appearance that takes material;
5, because cutter diameter is less, need not protect especially, be difficult for hurting operating personnel, security is good.
