The structure principle, motion form and requirements of the gantry planer are introduced
Longmen planer, is a kind of machine tool, in large machining, very commonly used, it can be used to cut large workpiece, or multiple workpiece cut at the same time, so brought great convenience to production and processing, we will know it, the following will be introduced from several aspects, the specific content, please pay attention!
1. Structure principle
The movement of the gantry planer is mainly the movement of the workbench, the workbench is generally with the workpiece for straight reciprocating movement, and the planer is a horizontal or vertical intermittent movement, so its knife frame can move in the horizontal and vertical direction. In addition, the gantry planer is driven by a DC motor, and can perform stepless speed regulation, so its movement is very smooth.
2. Form of movement
The movement form of the gantry planer has: the main movement, the feed movement and the auxiliary movement, the main movement refers to the working table, the feed movement refers to the knife frame, the auxiliary movement refers to the adjustment of the tool.
3. Process characteristics and its requirements for the automatic control system
Reverversibility: during processing, the workbench is moved repeatedly; when working, the workbench is shaved; and when returning, the workbench is empty load return.
Speed range: the cutting speed of the gantry planer are cutting conditions, tools and workpiece materials. Workbench for different work, should have different cutting speed, so it should have the corresponding different speed, can be adjusted.
Static difference: if the surface of the workpiece is uneven, or the material is not very uniform, then the cutting force will fluctuate, resulting in the static difference. If the fluctuation is very large, then it will affect the machining accuracy and the surface finish.
Rapidity: refers to the positive and negative direction of the table to start and the braking process to be fast, stop quickly, so as to improve production efficiency.
There is a certain interlocking protection: mainly for the gantry planer can be normal and reliable operation and take protection measures or interlocking protection device.
