Description

End cover forming and cutting intelligent production line and method for mechanical arm dispatching Technical Field The invention relates to the technical field of intelligent manufacturing equipment, in particular to an intelligent end cover forming and cutting processing production line and method for mechanical arm dispatching. Background The end cover is used as a key sealing part in pressure vessels, heat exchangers and various shell devices, and the processing quality of the end cover directly influences the integral air tightness and pressure resistance of the device. In particular, in products such as air-conditioning oil separators, the end cover can meet the assembly requirement through a plurality of procedures such as blank forming, trimming, finish machining and the like. In the current industry, a mode of sequentially operating a plurality of independent devices is generally adopted for processing round end cover parts, namely, after blank stamping forming is finished by a hydraulic press, a semi-finished product is manually conveyed to a common lathe or a numerical control machine tool for subsequent trimming and finish machining. In a specific machining process, an operator firstly puts a metal blank into a hydraulic die for stamping forming, after stamping is finished, a semi-finished end cover with high temperature or certain deformation is manually taken out, and then the semi-finished end cover is transferred to another machine tool for clamping and positioning so as to finish the cutting machining of the outer edge of the end cover. Under the condition of double-sided processing, the clamping gesture of the end cover is often required to be manually adjusted, and the two-time or even multiple-time clamping is performed. The production mode formed by combining single-machine equipment and manual transportation has the following problems: First, the joint transport between the processes makes it difficult to unify the positioning references of the end caps among the plurality of processing units. Repeated positioning errors can be introduced in each time of manual taking, placing and clamping, particularly after a semi-finished end cover is stamped, the gesture of the semi-finished end cover is often changed randomly, and the semi-finished end cover needs to be realigned in the subsequent machining process, so that the auxiliary time is prolonged, the thin-wall end cover is deformed due to uneven stress caused by repeated clamping, and the machining precision of a sealing surface is further affected. Secondly, due to the lack of a special overturning and posture adjusting device, for the end cover needing double-sided processing, an operator has to carry out multiple clamping. Under the ordinary processing mode, the positioning standard of clamping is different at every turn, causes the uneven processing allowance easily, and the phenomenon of dislocation even appears, leads to the product uniformity relatively poor. Disclosure of Invention Aiming at the defects of the prior art, the embodiment of the invention aims to provide an intelligent end cover forming and cutting processing production line and method for mechanical arm scheduling, which solve the problems of poor positioning precision, low processing efficiency and difficult guarantee of product consistency caused by scattered procedures, manual transportation and repeated clamping in the traditional processing mode through integrated production line layout and automatic material circulation, so as to realize continuous and high-precision manufacture of end covers from blanks to finished products.
