Transflex Transflex flexible manufacturing system for my company cooperation with Sweden MODIG company development and design of a new type of the flexible manufacturing system consisting of multiple spindle machining center.Transflex perfect adaptive ability, the unit of work and conveyor line, with zero, multiple spindle high-speed machining tool change time and with the advantages of the linear motor drive.Because the machine has the linkage of the feed shaft, dynamic spindle interpolation function, thus able to automobile, aviation and other fields require high machining accuracy, surface roughness requirement of high quality, the outline of complex and multifaceted porous parts, milling, interpolation and milling, drilling, boring, thread milling and the efficient composite processing of tapping screw thread, and other procedures.Transflex excellence in composite processing mainly comes from the following core technology.
(1) high production efficiency and adaptability: due to the use of numerous technologies such as tool change time, so the central processing equipment operation time is reduced effectively, so as to achieve the high productivity.Since all the spindle has its own knife library system, so each spindle can meet the requirements of different processing methods, achieved good adaptability.Through rapid locking positioning fixture positioning device, reduces the workholder transposition of time.Time:
(2) no change knife in the other main shaft running at the same time, the equipment complete change in the background.Before getting into processing position, the speed of the spindle has reached the required.Based on this principle, the spindle acceleration, deceleration and tool change time will be deducted from the cycle time.
(3) the optimization of the spindle system: according to the application conditions and customer requirements to determine the number of main shaft, up to 10 root spindle can be installed.For all the purpose of the main shaft of the optimization.Spindle machining scope of tapping screw, laser, milling, drilling, grinding, and powerful processing, etc.
(4) no repeated clamping workpiece: TransFlex can install up to 10 horizontal or vertical spindle, at the same time with up to 5 axis of workpiece positioning system, which can, in most cases, more complete individual artifacts surface processing.
(5) outstanding dynamic performance, match with linear motor.TransFlex high speed and high acceleration, through in the X, Y, and Z up use linear motor, can achieve very high interpolation and position tolerance.
(6) auxiliary time is short, can be done automatically fixture replacement, at the same time can be done in a few seconds the main shaft of the cutter disc replacement, can also according to the production requirements to determine each cutter tool number.
Transflex flexible manufacturing system local area, the overall shape and the machine is mainly suitable for aerospace, military industry and automobile industry such as small to medium size of housing, housing and cylinder head and other parts processing.
(2) HOUSING parts processing scheme with MAGNA company LG HOUSING parts as an example, the whole process and the technological process are described below.
magna cylinder shell specifications for 239 mm * 193 mm * 198 mm, the material is AlSi9Cu3, parts machining parts with A datum, G face, A ‘face, G and D.
artifacts based on third class high surface (X1, X2, X3) and two taper hole 2 (R1) positioning hydraulic clamping, machine tools with the fourth axis rotation.
spindle selection and distribution of cutting tool, eight independent spindle unit and the knife library according to the principle of process optimization are arranged at both sides of the processing area.Machining parts and process the beat is as follows:
(1) A datum.Processing step work with plane milling, drilling, reaming, boring and tapping screw, machine and beat, get A datum plane cutting time of 45.01 s.
(2) G datum.Step processing industry has a plane milling, milling ring groove back, drilling, reaming, boring, boring and tapping screw, machine and beat, get G datum plane cutting time of 42.87 s.
(3) the back of A datum – A ‘datum.Processing step milling flat, composite drilling and tapping screw, etc., and machining the beat, to get A ‘datum plane cutting time is 11.93 s.
(4) G datum on the back — G ‘datum.Processing step work with milling flat, chariot, drilling and tapping screw, machine with the beat, get G ‘datum plane cutting time is 6.98 s.
(5) D datum.Processing step work with milling flat, chariot, drilling and tapping screw, machine with the beat, get D datum plane cutting time of 1.32 s.
(3) when machining time distribution and production capacity of
parts Transflex can achieve rapid positioning, its main shaft positioning the total time is 52.02 s, time is 20 s, loading and unloading workpieces cutting time is 111.3 s, the total processing time is 183.28 s.
4. Conclusion in
, two Transflex equipment can complete the task of annual output of 300000 pieces, and needs only one clamping workpiece, the multi-channel process after the accumulated error is small, significantly improved the precision of machining of complex, reduce the sets and covers an area of the machine tool, simplifying the material flow, shorten the entire process, reduces the technical limitations on the product design.
