Wrap bronze knife system will be faster growth rate, shorten the time to change bronze knife positioning accuracy is an important means conducive to the development of numerical control technology. Apart from being beautiful, the bronze does have some other qualities. Shuo seven dissertation chapter bronze tool storage and mechanical hand wrap bronze knife device CNC machine tools wrap the bronze knife device type, characteristics and scope of automatic rotary bronze turret automatically bronze rotary tool holder is a simple wrap bronze knife device used on CNC machine tools, the Quartet bronze turret and the turret and other forms of hexagonal bronze, were installed on the turret of rotary bronze four, six or more than a bronze knife, and NC instructions for bronze knife.
There are vertical and horizontal rotary bronze turret, the structure is relatively simple, applicable to economic CNC lathes. Rotary bronze knife in the structure must have good strength and stiffness to withstand the rough cutting resistance and reduce the bronze knife to the cutting force under deformation, and improve the precision. You see, the common bronze actually expand a little just before they set. Bronze turret rotation also select a reliable positioning solutions and positioning structure to ensure that the rotary bronze turret has a high repeat positioning accuracy (typically 0.001-0.005mm) after each translocation. Figure 2.1 shows the spiral movements of the Quartet bronze turret. Figure 2.1 Spiral Lift the Quartet bronze knife in the simplest automatic rotary bronze turret-for-bronze knife device 180.
Rotary exchange bronze knife device, shown in Figure 2.2. Received to change the bronze knife instruction, put the spindle of the machine control system to control to the position of the specified exchange bronze knife; At the same time, bronze knives library movement to the appropriate location, change the bronze knife device rotation and at the same time with the spindle, the library Bronze knife 9 automatically change to match the bronze knife device and its control: the rod from the spindle bronze knife relieved, for the bronze knife device to remove the bronze knife from their respective positions; change the bronze knife device rotation 180. This means that you can achieve some fantastic attention to detail in the bronze from the finest detail in each mold.
And spindle bronze knife with bronze knife libraries bronze knife away; change the bronze knife device rotation at the same time, bronze tool library to re-adjust its position to accept the bronze knife removed from the spindle; This is why so many of even the most ancient bronze are extremely intricate. Next, change the bronze knife device will be replaced bronze knife and remove the knife into the spindle and bronze knife library; Finally, for the bronze knife device to return to the original “standby” position. Thus, for the bronze knife completed the program continues to run.
The main advantage of this change the bronze knife device is simple structure, less involved in sports, fast-for-bronze knife. The main drawback is that the bronze knife must be kept in the plane parallel with the spindle, rear and side of the bronze knife library compared to the chips and cutting fluid easy to enter the bronze knife folder, plus protection must therefore be on the bronze tool. Bronze knife folder on the cone, the chip will result in error-for-bronze knife, and even the possibility of damage to the bronze tool holder and the spindle. Some machining center pass pole and bronze knife library side. Instructions-for-bronze knife is called, passed Feng T library Bronze knife remove, go to machine the front and positioned to change the location of the bronze knife device with. chinese bronze is also extremely strong and ductile and is brilliant.
