Components of automatic fiber cutting machine equipment

The main technical parameters of the group of automatic fiber cutting machine equipment can cut the range of pipe diameter and wall thickness: equipment composition This group of automatic fiber cutting machine is mainly composed of flame cutting system, mechanical system and control system. The simple circle flame cutting system of the group of automatic fiber cutting machines, the system mainly includes: oxygen and gas sources, oxygen and gas pressure gauges, oxygen and gas flow regulators, flashback preventers, electromagnetic control switches, automatic ignition devices, Flame cutting torch and cutting torch holder, etc., as shown in Figure 3. Its main function is to realize the automatic ignition of the flame cutting torch and make it meet the requirements of the cutting process through the adjustment and switch control of the oxygen and gas pressure and flow. The cutting process of the group automatic fiber cutting machine system is as follows: adjust the oxygen and gas regulators, turn on the solenoid valve 4, turn on the ignition device, turn on the solenoid valves 1 and 3 to preheat the workpiece, and close the solenoid valve 4 to preheat When the temperature reaches the ignition temperature, open the solenoid valve 2 to cut the workpiece. After the cutting is completed, close the solenoid valve, and the oxygen gas flame cutting system indicates the circle. The mechanical system of the machine consists of the spindle box, the bevel cutting device, the gantry and the guide rail, It is composed of rolling support and wire rack. The headstock is mainly used for clamping pipe fittings and completing its rotating movement. The spindle box drives the reducer through an AC servo motor, thereby driving the gear to rotate, and then driving the main shaft and the three-jaw chuck to rotate.

Taiwan group automatic fiber cutting machine adopts harmonic reducer, staggered gear, fixed front point and free back point of the main shaft, etc., so that it has a large load capacity and high rotation accuracy. , The characteristics of small backlash, etc., meet the accuracy requirements of the automatic fiber cutting machine for the tube group group. The bevel cutting device adopts a two-way swing mechanism (around the shaft, shaft), which can complete the cutting of the full bevel angle of the pipe. Its structure is that the servo motor drives the gear through the worm gear reducer to drive the cutting tool to swing around the shaft along the arc guide rail, and the arc guide rail is driven by the servo motor to swing around the shaft. The gantry is driven by a rack and pinion to drive the groove cutting device to reciprocate along the guide rail. In order to cut pipes of different diameters, the gantry is equipped with a driving mechanism to drive the groove cutting device to move along the direction. The rolling support acts on the distal end of the tube, ‘plays the role of auxiliary support. The rolling bracket can move freely along the axial direction on the bracket rail to meet the cutting needs of different lengths. Control system The machine adopts the structure of IPC+ numerical control function board to design the numerical control system of the group automatic fiber cutting machine. In terms of hardware, with industrial computer as the core and CNC function board as the basic component, the modular design of the CNC system is carried out; in terms of software, it is carried out according to the design layer, operation planning layer, process control layer, motion control layer and axis control layer. Hierarchical division, so as to design a certain open CNC system suitable for processing. The main research content is divided into the following aspects: (1) The selection of the multi-axis control mathematical model of the phase cutting machine system.
