Metal spinning is that part is installed in core and rotates with it, spinning roller also can be made to rotate around part, spinning roller feeding relative to core, makes part pressurized and produces continuous pointwise distortion.This is a kind of forming technology producing revolving parts.Mainly conventional spinning and shear spinning in spinning process, the latter can be divided into again forward spinning and reverse spinning by spinning roller and blank flow direction.
Mould pressing as the important component part of machinery manufacturing industry, towards more smart, Geng Sheng, cleaner future development.Not only shape, size before forming, after can not need machining or only need a small amount of processing, and there is high surface quality and excellent structure property.Adopt spin forming technique can realize high efficiency, low consumption, low cost, improve the capability of fast response that engineering goods multi items becomes batch production.
The conventional reverse spinning of cnc spinning machine adopts numerical control programming to control mandrel rotary velocity and spinning roller feeding control tubular parts size precision, for the mould pressing with step deformation wall thickness part, as Fig. 1, only very difficult by the interlude length that numerical control programming control tolerance grade is tighter, need strict the wall thickness dimension precision and the density of material that control part, also need to readjust spinning parameter after changing spinning roller, virtually improve part machine and add precision and difficulty, repeatedly debug spinning parameter and also improve part scrap rate, reduce production efficiency.
Summary of the invention
The present invention has the wayward problem of step deformation wall thickness part interlude (4) length dimension in order to solve existing cnc spinning machine by means of only numerical control programming spinning, and then proposes a kind of cnc spinning machine reverse spinning tracking manufacturing process.
The present invention proposes the reverse spinning of a kind of cnc spinning machine and follows the tracks of manufacturing process: oppositely spinning tracking means includes main part, length feed part, traverse feed part and follower head part; Main part is made up of welded base, is fixed on former lathe balladeur train; Length feed part is made up of rolling guide and ball screw block; Traverse feed part is made up of rolling guide part; Follower head part have by the prolongation situation of part in the gauge head energy perception spinning process of driven by servomotor.
It is as follows that the reverse spinning of cnc spinning machine of the present invention has step deformation wall thickness part tracking manufacturing process:
With the opposite direction that spinning roller (1) moves from right to left along part axial, namely part axial is from left to right X-direction, with from axis of workpiece outward radial for Y-direction, the origin of coordinates is positioned at center, part left side;
Step one: first gauge head advances, and the position, right part of part detected, gauge head lifts and rollback falls to X-direction coordinate a position and fixes, and spinning roller runs to the X-direction coordinate b position just contacted with part right-hand member and prepares spinning, as Fig. 3 simultaneously;
Step 2: spinning roller moves to part right part and touches X-direction coordinate a position gauge head from X-direction coordinate b against X-direction, complete part right part and to top bar part 2 spinning, now spinning roller X-direction coordinate is d, as Fig. 4;
Step 3: gauge head lifts and retreats and falls to X-direction coordinate c place, and spinning roller is moving to X-direction coordinate e position from X-direction coordinate d, completes part and tops bar partly to right changeover portion part 3 spinning of interlude 4, as Fig. 5 from right part;
Step 4: spinning roller continues inverse X-direction and runs, until part right part touches the gauge head of X-direction coordinate c position again, complete the spinning of part interlude 4, now spinning roller is in X-direction coordinate f position, as Fig. 6;
Step 5: gauge head lifts and retreats, spinning roller is moving to X-direction coordinate g position in inverse X-direction, completes part interlude and to top bar left changeover portion part 5 spinning partly, as Fig. 7 to left part;
Step 6: spinning roller moves to X-direction coordinate h position against X-direction, completes part left part and to top bar the spinning of part 6, as Fig. 8.
The invention has the beneficial effects as follows: reverse spinning tracking means improvement and installation is carried out to cnc spinning machine, the probe location being read this device and feature contacts by system controls step interlude length dimension, the mould pressing with the change wall thickness part of step shape is realized under the prerequisite not improving part Wall-Thickness Difference precision, ensure dimensional accuracy, the machine reducing part adds precision and difficulty, thus reduce part scrap rate, improve production efficiency, extend the spinning ability of this equipment simultaneously, improve the utilization rate of equipment.
