Composition of automatic tool changing device of machining center
coupling agent KH (5) 50 can be added to machining centers such as PP plus glass fiber; 2. Add compatibilizers for surface connection treatment. For example, PP-g-MAH (PP Grafted Maleic Anhydride) can be added to PP with glass fiber. It is developed from the basic CNC milling machine. It integrates all the characteristics and functions of CNC milling machine. Different from CNC milling and even less than 5% of the machines, the machining center has an automatic tool change device, which can realize the function of moving and changing tools in plastic extrusion molding equipment during processing. The CNC milling machine has no automatic tool change device, which can not automatically change the tool in the process of cooperation with many foreign merchants. This is the difference between CNC milling machine and machining center. Today, let's introduce the automatic tool changing device
composition of automatic tool change device of machining center
the automatic tool change device of machining center is composed of tool magazine, manipulator, driving mechanism and other components, and the tool magazine is used to store the tools required for processing. There are many types of tool magazine, mainly classified according to shape. There are many types of tool magazine, such as hat type tool magazine, disc type tool magazine and chain type tool magazine. The capacity of these tool magazines is several to hundreds of tools. In the market, there are two kinds of tool magazine commonly used by machining centers: hat type tool magazine and disc type tool magazine, while chain type tool magazine is not used by many manufacturers because of its high price. Now let's introduce the tool changing method
tool change method of hat type magazine
the tool change method of hat type magazine is relatively simple. This kind of magazine does not have a manipulator, so it does not need to use a manipulator to complete the tool change. The tool change mode of the tool magazine is as follows: the tool magazine moves to the spindle to realize tool change. This type has the advantages of high cost performance, convenient maintenance, simple structure and so on, but the disadvantage is that the tool change speed is slow
tool change mode of disc magazine
the tool change mode of disc magazine is relatively complex, which is mainly completed by the manipulator. The manipulator takes out the tool from the magazine and rotates it 180 ° to install it into the spindle to complete the tool change. This kind of tool magazine has the advantages of fast tool changing speed, but its disadvantages are complex structure, inconvenient maintenance, and high failure rate
although the tool change mode, tool selection mode and tool structure of these tool libraries are different, they are all controlled by the numerical control system, and the tool selection and exchange are realized by the motor, pneumatic or hydraulic pressure and manipulator
