Summary: Basically be the function of circular arc interpolation that uses 20PM, when because be in,the machine that fold a turn bends a few short canals, control is bad, may copper pipe squash. Though PLC also supports circular arc interpolation, but using on have a lot of restriction. On this equipment, the around on cantilever of use 20PM control and fluctuation two axes, equipment pulls copper pipe to do circular arc interpolation to curve copper pipe figuration through cantilever. In be being debugged later, according to effective demand, change circular arc involute, with period have better bent housing effect. Keyword: Coordinate of involute of mode of bent housing of circular arc interpolation is calculated treatment of plasticity of material of 1 foreword canal is make semifinished product in order to provide material, pass plasticity process instrumentation, make the processing technique of spare parts tubal material. Because product of figuration of easy contented plasticity is light,plasticity tubal material is machined quantify, Jiang Ren is changed and low cost creates the demand that waits for a respect efficiently, accurately, already became advanced plasticity processing technique to face a of 21 centuries research and development important way. Bent housing of 2 numerical control 2.

1 bent housing craft has a lot of different bent housing technology in practice, set out from different point of view the classification that can have a variety of differring. Press normally in the project when bending, heat to can be divided heat up a turn for Leng Wanhe, to have core according to bending to be able to be divided without filler from time to tome bent housing is mixed the bent housing that do not have core. Having a model to curve figuration is to show tubal material bends be out of shape the area does not suffer the effect to the mould directly, final figure is decided by the opposite motion of tool and workpiece, belong to height agile flexible process instrumentation. The model curves figuration is to show through rigid mould immediate effect is out of shape at bending area and the tubal capable person that have bends, ask dimension of part of this rigid mould action can be compensated make after uninstalling, happen curve spring back, belong to but the process instrumentation with tall and fast repeatability. A few kinds of new technology include bent tubal material thermal stress bends; Be based on tool motion pilot to bend without the model; Addition method bends; Numerical control machine tool circles a turn to wait a moment. 2.

Bent housing of numerical control of bent housing of 2 numerical control is in clamp tubal material curve a model, along with curve a model to turn together, when the canal material has been pulled pressure piece when, pressure piece be about to be in charge of material to circle a turn to be in curve a canal, belong to figuration model to curve craft. The conventional technology that circle a turn is to circle a turn by hand more, efficiency is low, quality assures hard. As the development of course of study of numerical control machine tool, use machine tool of advanced numerical control bent housing to implement the technology that circle a turn, can improve manufacturing efficiency greatly, assure the quality of the product. Because can adjust conveniently craft parameter, because pipe bender of this numerical control is OK already accurate finish steadily again bend, send into, the movement such as corner, assured control curve accuracy. Numerical control pipe bender is OK and automatic continuously the space of different curvature radius curves figuration. Integrate corresponding database software system, control program still can be amended beforehand curve spring back quantity. But the mould structure of this craft (7) seeing a picture is more complex, make a quality sensitive to craft parameter, the requirement has sufficient pre-construction and development work. Make thin wall control to the turn especially circumstance, if craft parameter choice is undeserved, appear very easily corrugate phenomenon brings about the spare parts is a mould even to discard as useless. How to get these craft parameter well and truly, assure quality of bent housing product adequately, it is the research heat that numerical control circles curved craft. System of bent housing of 3 numerical control 3.

1 system composition is based on a stage to amount to the equipment of numerical control bent housing of Electromechanical unifinication platform to share 6 motion shafting, craft asks among them two axes need linear interpolation, two axes need circular arc interpolation, two axes do not have other to ask particularly. What PLC controller chooses is 32EH00T2 and 20PM00D, showing what choose partly is 10.

Bent housing of controller of 2 20PM motion controls systematic core to amount to athletic controller DVP-20PMMOOD to form by the stage. The stage amounts to DVP-20PM00D is one has what motion controls special function to be able to make up Cheng controller. The biggest characteristic of DVP-20PM00D is PLC lead plane provides electronic cam function directly, perhaps say DVP-20PM00D is inside the PLC of function of buy electron cam, some places are so direct appellation DVP-20PM00D amounts to 20PM motion controller for the stage. 20PM has the input of 2 500KHz and output, in electronic cam function definition X axis is from the axis, coder inputs an axis to give priority to an axis, after defining good CAM Table, the curve that defines from axial basis follows main shaft moves. Use configuration of high speed double CPU, use independent CPU to handle motion to control algorithm, can realize all sorts of athletic contrail control, logistic movement control well, linear / control of circular arc interpolation, numerical control pipe bender used the electronic cam function of 20PM motion controller to solve complex motion contrail to control a problem just about. Process designing of bent housing of Nextpage420PM numerical control is designed 4.

Mode of 1 curved model machines a requirement according to bent housing, developed pattern of craft of two bent housing, refer to a graph 1 is shown. Graph mode of 1 bent housing 4.

Equipment of 2 technological process parts company move and automatic mode, basically be to include equipment to answer fixed length of origin, cantilever to advance below type of hand movable mould / fixed length of regressive, cantilever rises / drop and the hand when curved short canal uses curved model. The voluntary technological process of equipment divides A mode and B mode, part the A flow below correspondence and B flow, the switch between flow is finished through man-machine. Be in specific in carrying out, PLC gives priority to controller, choose with what will control flow and jump turn etc, give PM the order through PLC at the same time, in order to complete the work that PM place loads. Graph Nextpage of flow chart of mode of A of 2 curved models pursues flow chart of mode of B of 3 curved models 4.

Because 20PM oneself does not support the interpolation function of involute means,3 involute coordinate is calculated, be in so specific in carrying out, divide involute into much dot according to bent angle, through man-machine computation gives every coordinate of the dot, final PM realizes the function that the user asks through doing linear interpolation. The specific involute equation that gives out at that time: X= (R+H) *sin α + (L- α *R) *cos α Y= R- (R+H) * Cos α + (L- α *R) *sin α among them L, r, h is constant, can be through man-machine set when computation, the macroinstruction that writes for precaution causes an effect to the executive speed of man-machine, pass picture Cycle grand the computation that will realize coordinate, manipulate rate with respect to what won't affect man-machine other page so.

0normal Align=left>endifnormal >end5 last word stage amounts to PM20 motion controller to be in interpolation of executive circular arc and carry out successional behavioral flow respect to be close to more at system of professional numerical control, having the advantage that PLC place cannot compare, although carrying out the flexibility respect of order flow, still have certain space with PLC. Curve a spare parts with what tubal material makes, no matter be planar,bend, still be the space bends, divide a large number of application at duct of gas, liquid outside the road, the application in metallic structure is very wide also. Because this is in charge of material to curve figuration craft,be the main field that get attention fully and gets developing quickly, the research that begins this side works, have very important sense.
