A kind of pipeline shearing device
The present invention relates to a kind of shearing device, especially relate to a kind of pipeline shearing device.
Existing pipeline shearing device generally includes feeding mechanism and by the tool rest and the cutting knife formed of blade that are coupling mutually together, the advantage of this traditional shearing device is simple in structure, but because each cut-out is produced by moving up and down of blade, therefore also exist the slow shortcoming of cut-off velocity.In addition, the pipeline of cut-out also can be scattered everywhere, also needs to spend manpower and time to put in order.
Summary of the invention
Technical problem to be solved by this invention provides the pipeline shearing device that a kind of cut-off velocity pipeline fast, after cutting off is placed in order.
The present invention solves the problems of the technologies described above the technical scheme that adopts: a kind of pipeline shearing device, comprise feeding mechanism and cutting knife, described cutting knife comprises first guide pipe that fixedly installs with respect to described feeding mechanism and is provided with the runner of rotating drive mechanism, the described first guiding plumber block is provided with pilot hole, described pilot hole comprises charging aperture and discharging opening, described charging aperture is arranged near described feeding mechanism one side, be set side by side with a plurality of stock chests that run through described runner on the periphery of described runner, described discharging opening is provided with first blade, the opening of described stock chest is provided with second blade that cooperates with described first blade, the arranged outside of the periphery of described runner has with the not contacted circular arc baffle plate of the periphery of described runner can not drop the cut-out pipeline, the below of described runner is provided with and cuts off the pipeline gathering-device, and described circular arc baffle plate is provided with the blanking port that the cut-out pipeline that makes in the described stock chest falls into described cut-out pipeline gathering-device successively.
Described pilot hole can be circular hole.
Described pilot hole can at least part ofly be conical bore also, and the diameter of described charging aperture is greater than the diameter of described discharging opening, and the diameter of described discharging opening equals the external diameter of pipeline.
Described feeding mechanism comprises bin and one group of drawing-inroller, and described drawing-inroller is sent the pipeline of winding on described bin into described charging aperture by rotating.
Can also be provided with second guide pipe between described drawing-inroller and the described bin.
Compared with prior art, the invention has the advantages that by first blade that is arranged on second blade on the runner and be arranged on first guide pipe and constitute cutting knife, because the periphery of runner is provided with a plurality of stock chests, therefore as long as set the feed rate of certain runner slewing rate and corresponding feeding mechanism, just can realize pipeline cutting fast; And because the setting of circular arc baffle plate was cut off pipeline all can be deposited in the stock chest before arriving blanking port, cut off in the pipeline gathering-device up to entering in an orderly manner successively in blanking eloquence; And pilot hole partly or entirely is conical bore, and the diameter of discharging opening equals the external diameter of pipeline, then the erose pipeline of original winding on the material wheel can be proofreaied and correct to be circular pipeline.

The specific embodiment
Describe in further detail below in conjunction with the present invention of accompanying drawing embodiment.
Embodiment one: a kind of pipeline shearing device, comprise feeding mechanism 1 and cutting knife 2, cutting knife 2 comprises first guide pipe 21 that fixedly installs with respect to feeding mechanism 1 and is provided with the rotating drive mechanism runner 22 of (figure does not show), first guide pipe 21 is provided with pilot hole 211, pilot hole 211 is circular hole, pilot hole 211 comprises charging aperture 212 and discharging opening 213, charging aperture 212 is arranged near feeding mechanism 1 one sides, be set side by side with a plurality of stock chests 221 that run through runner 22 on the periphery of runner 22, discharging opening 213 is provided with first blade, the opening of stock chest 221 is provided with second blade that cooperates with first blade, the arranged outside of the periphery of runner 22 has with the not contacted circular arc baffle plate 23 of the periphery of runner 22 can not drop the cut-out pipeline, the below of runner 22 is provided with and cuts off pipeline gathering-device 3, circular arc baffle plate 23 is provided with the cut-out pipeline that makes in the stock chest 221 and falls into the blanking port 231 that cuts off pipeline gathering-device 3 successively, feeding mechanism 1 comprises bin 11 and one group of drawing-inroller 12, drawing-inroller 12 is sent the pipeline of winding on bin 11 into charging aperture 212 by rotating, and is provided with second guide pipe 13 between drawing-inroller 12 and the bin 11.
Embodiment two: other structure is identical with embodiment one, and difference is that the leading portion of pilot hole 211 is conical bore, and the diameter of charging aperture 212 is greater than the diameter of discharging opening 213, and the diameter of discharging opening 213 equals the external diameter of pipeline.
