The machine tool that uses direct drive technology is assembled not only compact, move smooth, and raised precision, the chance of mould pressing cut that reduced cost tradition uses the means of positive drive, not only the structure is complex, cost is higher, and the demand that makes the same score stability and precision to satisfy a client hard. Company of the treatment after more and more imprinting had realised this, used direct drive technology to undertake redesigning to machine of cut of its mould pressing gradually, not only reduced machine part, reduced noise, and the precision that promoted a machine considerably, improved the overall productivity of machine of mould pressing cut thereby. Alleged and direct drive rotates direct drive namely electric machinery (DDR) or direct drive is steep electric machinery (DDL) direct coupling or join arrive on driven load, realize the rigid coupling with load thereby. Because cancelled the part such as transmission leather belt and gear case, direct drive solution simplified machine design, eliminated the function that place of the mechanical drive with bigger noise and this kind of drive accompanies to restrict, have maintenance-free, tall stiffness, need not precision of lubricant, fixed position tall, rate is stable, move quiet wait for an advantage, because this is become,presswork, pack the good choice that waits for domain application, raised the productivity of equipment and dependability greatly. In the meantime, because assemble compact, component,little, installation is mixed use convenient, still can help OEM manufacturer promote the product quickly to the market. Direct drive rotates electric machinery, also call torsion electric machinery sometimes, can get on laden and direct link to electric machinery, taller torsion can arise when relatively inferior speed, applicable at high speed chip grading machine. The profit that DDR can bring for the client has: Clean mechanical part; Servo function rises, DDR can raise precision 50 times; Maintenance-free, DDR did not need Zhang Jin and adjusted leather belt already, also can not produce leak and need lubricant gear; Repeatability rises; Shorten machine machine down time; Moving noise is low, noise can be reduced be as high as 20db. Cartridge DDR (CDDR) the newest and patent product that electric machinery is drive of red accept conspicuous, the installation that is the advantage on the first kind of will not have technology of frame electric machinery economic space inside course of study and function and complete frame electric machinery is handy the electric machinery that sexual photograph integrates. CDDR electric machinery is rectified by a rotor, stator and job finalize the design composition of device of high resolution feedback, itself does not contain bearing, when installation arrives on the machine, the rotor of electric machinery comes through the existing bearing of the machine bearing. The impaction shaft coupling of innovation goes to rotor clench the teeth on load, make both be in harmony is an organic whole, eliminated electric machinery and load between flexible. The frame of CDDR electric machinery passes as identical as groovy servo electric machinery bolt circumferential go up to the machine with installation of feed hole diameter, saved space and design time, simplified whole system. CDDR has CE attestation and contented UL whole world applies a standard, can use at 230V, 400V and 480V voltage, with satisfying the biggest design flexibility is mixed move dovishly. CDDR has norms of 5 kinds of frame, include 4. 25, 5.
4, 7.
4, 9.
8 with 13.
7in2 (1 In2=6.
45 × 10-4m2) . What CDDR uses is S300 and system of S600 standard drive, c09 and C13 have via options. CDDR successive torsion is 4.
6~510 Nm, peak value torsion is 11.
3~1017Nm, the biggest rotate speed is as high as 2500r/min. Configure photograph comparing with electric machinery of other and direct drive, CDDR electric machinery is mixed in cost effectiveness use there was remarkable leap on convenient sex. The setup that has frame electric machinery and feedback unit and debug need time of a few months, and CDDR needs to aim axis and oriented device handily only, take out the time that begins movement to need 5min only from inside box of have a change of luck. CDDR electric machinery can be installed on aleatoric direction, include horizontal axis or vertical axis installation. The machine of mould pressing cut that what the company of the treatment after imprinting with a lead whole world uses at first is positive drive, mix to the precision of the machine tool as the user however of the requirement of efficiency rise ceaselessly, original transmission way far the demand of short of client. This enterprise realized the profit of direct drive technology later, give priority to in order to obtained the CDDR electric machinery of patent technology, undertook redesigning to machine of their cut of whole mould pressing. The get rid of in the machine of new design besides belt of gear, timing, gear case, bearing, box of oiling of installation bracket, gear, phasic implement, electric machinery of pneumatic clutch, leather belt annulus, position and more than 100 spare partses. This design brought distinct benefit for this enterprise, not only reduced noise 20+dB, component amount reduced more than 100, and precision enhanced 10 times above, overall productivity raised the machine tool 20 ％ . The project manager of this enterprise expresses, the machine of mould pressing cut that used direct drive technology is the smoothest type that they had seen at present. The machine tool that their client has redesigned to this showed very interest, had been head and shoulders above their imagination to its demand. An among them Germany client is in after seeing this new machine tool, immediately cancelled original order, and say, "I should change such machine tool. "I should change such machine tool..
