Fig. 2 is the system architecture sketch map of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further detailed explanation.
As shown in Figure 2; Present embodiment is a kind of automatic diameter changing pipe cutting machine, comprises PLC control system 1, the man-machine interface 2 that receives user's input parameter, rotation feed controller 31, rotation feed motor 41, cuts with movement controller 32, cutting follow-up motor 42, pipe support and control device 33 and pipe support motor 43:
The input of PLC control system 1 is connected with man-machine interface 2; The output of PLC control system 1 is connected with pipe support and control device 33 with movement controller 32 with rotation feed controller 31, cutting respectively; Rotation feed controller 31 is connected with rotation feed motor 41; The feed initial point of 41 pairs of tubing of control rotation feed motor, cutting is connected with cutting follow-up motor 42 with movement controller 32, the feed total amount of 42 pairs of tubing of control cutting follow-up motor; Pipe support and control device 33 is connected the bearing height of 43 pairs of tubing of control valve support motor with pipe support motor 43.
Man-machine interface 2 is as shown in Figure 1:
The user imports all kinds of parameters through man-machine interface 2:
1. Diameter: pipe diameter is set φ.
2. Wall thickness: tube wall thickness δ sets.
3. Limit: the limit initial point of blade (this positional value is fixed as " 0mm ").
4. pipe center: the center of tubing also is the limit terminal point of blade.
Man-machine interface 2 dynamically shows following parameter:
1. Start: feed initial point (indicate in scale through the arrow in the picture position).
2. tubing marginal position indication: the point width of expression blade is from the actual range of pipe outer surface.This position can change according to the bearing height of tubing automatically.
3. scale: indicate each positional value
4. the physical location symbol of blade: in the process of feed or withdrawing, this position symbol can dynamically change.
1, the position computing of feed initial point Y:
In the cutting of tubing, in continuous production, be unlikely to answer back to blade in order to make tubing, it is far away more that the tubing that diameter is big more, feed initial point will leave cutting machine rotation cutting center; On the contrary, the tubing that diameter is more little is not turned the distance at feed initial point and cutting center down; Though can not answer back to blade,, the distance of the feed of cutting and withdrawing can extend; Also can extend greatly the cycle time of cutting, do not reach line speed, therefore at all; Feed initial point Y and pipe diameter φ exist the relation of linear inverse ratio, and pipe diameter is big more, and the position of starting point is more little; This point can be found out (among Fig. 1, influenced by the man-machine interface picture size, pipe diameter is represented through tubing edge edge) from Fig. 1.We represent this linear inverse relation through equation: Y=a* φ+b; Wherein φ is a pipe diameter, and Y is the feed initial point, if can obtain a, b value; As long as set pipe diameter φ, PLC control system 1 promptly obtains feed initial point Y (being known by equation) through equation so.Can be known that by Fig. 2 the motion of blade is driven by control rotation feed motor 41, in a single day PLC control system 1 calculates feed initial point Y, and control rotation feed motor 41 will drive blade movement to suitable feed initial point Y, is exactly the computational methods of a, b below:
Cutting machine for a machinery has assembled accurately finds Ymax and Ymin through manual adjustments.Wherein, Ymax is the corresponding maximum feed initial point of maximum caliber that the automatic diameter changing pipe cutting machine is supported, Ymin is the corresponding minimum feed initial point of minimum pipe that the automatic diameter changing pipe cutting machine is supported.
According to equation, then have:
Figure 2011205509895100002DEST_PATH_IMAGE001
,
Calculating linear equation in two unknowns can obtain: a=(Ymax-Ymin)/(φ max-φ min), b=Ymax-φ max * (Ymax-Ymin)/(φ max-φ min)
PLC control system 1 calculates feed initial point Y=a* φ+b according to following formula, and PLC control system 1 sends feed initial point Y to rotation feed controller 31.
2, bearing height G position computing:
PLC control system 1 calculates bearing height G=c* φ+d according to following formula, and wherein c and d calculate through following linear equation in two unknowns:
Figure 887564DEST_PATH_IMAGE002
,
Gmax is the corresponding maximum support height of maximum caliber that the automatic diameter changing pipe cutting machine is supported, Gmin is the corresponding minimum support height of minimum pipe that the automatic diameter changing pipe cutting machine is supported;
PLC control system 1 sends bearing height G to control valve support and control device 33.
3, feed total amount Δ L computing:
Can know by Fig. 1: Δ L1=Lmax-Y-φ/2----------formula 1
Wherein Δ L1 is the feed distance of blade from feed initial point edge to the tubing edge; Lmax is that the feed ultimate range of limit initial point limit pipe_center to the tubing center of blade is (known; Be 150mm in the legend), Y is the initial initial point of blade, φ/2 are that the tubing radius is (known; Set diameter phi on the man-machine interface), so Δ L1 can be obtained by formula 1.
Feed total amount Δ L=Δ L1+ δ+δ 1---------formula 2
(δ is a wall thickness, and by setting in the man-machine interface, δ 1 wears surplus for cutting, and generally is made as 3mm)
In conjunction with formula 1 and formula 2, can draw:
Δ L=Lmax-Y-φ/2+ δ+δ 1----------formula 3
In formula 3, Lmax, Y, φ, δ, δ 1 is all known, and feed total amount Δ L=Lmax-Y-φ/2+ δ+δ 1 calculates according to formula 3 in PLC control system 1;
PLC control system 1 sends feed total amount Δ L to cutting with movement controller 32.
The withdrawing total amount that PLC control system 1 sends tubing to cutting with movement controller 32, the withdrawing total amount is identical with the feed total amount.
