Description

Material-increasing and material-reducing double-station synchronous machining method and device for spiral pipe parts

Technical Field

The invention relates to the field of desktop type laser material increasing/decreasing machining equipment, in particular to a material increasing/decreasing double-station synchronous machining method and device for spiral pipe parts.

Background

With the rapid development of the economic system in China, the usage amount of the revolving body type parts serving as the important foundation for the development of the mechanical industry (from daily life to aviation, aerospace, navigation and national defense industries) is gradually increased year by year. From the perspective of specific processing techniques and methods: the method has the advantages that the machining precision of the thinning material is high, but the energy consumption, the time consumption and the material consumption degree are also high, and the yield is low when the thin-wall part is machined; secondly, the efficiency of material processing is high, the energy consumption is low, the loss of raw materials is low, but the blank preparation process is complex, the design and manufacturing cost of the die is high, and the small-batch customized service requirement of a special structure is difficult to meet; the material increase manufacturing technology can meet a large number of special requirements of part machining, efficient forming of complex structures can be completed, and the problems of machining precision and machining surface quality are still difficult to solve. Therefore, the material increasing/reducing composite manufacturing technology is developed to meet the comprehensive requirements of high efficiency, high precision, low loss, low cost, high flexibility and the like in the forming process of the complex revolving body component.

The existing desktop type material increasing/reducing composite manufacturing equipment is often divided into two independent links by material increasing and material reducing processing. Although the clamping frequency of parts can be reduced, the processing flow can be shortened, and the processing precision and efficiency can be improved, the problem of interference between two processing procedures of material increase and material reduction is avoided to a certain extent. However, this causes the overall size of the equipment to be too large, a higher proportion of the total energy consumption and the total time consumption of the machining is lost in the reciprocating conversion link of the stations, and it is also difficult to realize the precise machining of the inner wall of the component with a large axial size and the surfaces of the inner and outer walls of the complex component with a non-linear change characteristic of the radius of the revolving body.

In the material increasing/reducing composite machining process, the workbench can only realize translation or rotation movement, and the operation is complex when machining the special revolving body parts with variable diameters, and the machining efficiency is low. On the other hand, a large amount of fine chips are generated at the time of cutting or grinding. If the complex transmission system comprising the multi-station composite manufacturing equipment is not subjected to targeted sealing design, a large amount of scraps are easy to adsorb, accumulate and block the meshing parts among transmission parts along with lubricating oil, so that severe abrasion is caused, the transmission and machining precision is reduced, the service life of key precision parts and equipment is shortened, the maintenance cost is increased, and even seizure of a working platform occurs in severe cases.
