Description
Technical field
The present invention relates to a kind of electrode automatic machining line, especially a kind of numerical control automatic machining line of electrode contact belongs to metallurgical electrode processing technique field.
Background technology
Electrode contact is the workpiece that a kind of two ends all are shaped on taper thread, is widely used in metallurgy industry.Because graphite electrode belongs to consumable material in steel industry, therefore be in great demand.Big in order to solve the feed driving error that original electrode contact thread cutting machine exists, processing is impacted big, and problem such as single cutter Milling Process work efficiency is low, the applicant had once designed the two chasing tool machining tools of a kind of numerical control electrode joint screw thread, and had applied for Chinese patent (99229426).The applicant feels more and more profoundly in constantly putting into practice, because the graphite electrode nipple manufacturing procedure is more, precision is higher, especially wherein taper thread chasing tool processing has unique technological requirement, so traditional unit is processed step by step, and not only work efficiency is low, and be connected between the operation uncertain, assurance to the finished product final mass is very unfavorable, and the result causes electrode in use to contact undesirable, loss increasing even fracture and come off easily.Find after consulting interrelated data, U.S.'s Ingersoll has successively been developed by electrode contact cutting-off machine, electrode contact spotfacing and centering machine, electrode contact outer cone lathe, the two screw threads comb of electrode contact machining tool, electrode contact brill keyhole dress bolt groove milling lathe with the only lathe company of getting over of Japan in recent years, and the graphite electrode nipple automatic machining line of conveying device and control system composition.Yet, these external processing lines are not only because domestic uncontested product, import price is very expensive, and have the following disadvantages: the one, whole processing line centralized Control, can't adjust separately flexibly, so the adaptability of processing line be relatively poor according to the situation of every equipment, not enough flexibility, being difficult to satisfy electrode contact processing should centralized Control, need the special requirement adjusted separately again; The 2nd, workpiece adopts platform-type conveying, needs ascending, descending clamping repeatedly, and the station of workpiece shifts and control is all convenient inadequately automatically, and floor space is big.
Summary of the invention
Primary and foremost purpose of the present invention is: at the deficiency of existing import processing line existence, by to the innovative design of control system and the improvement of equipment coupling, a kind of fully numerically-controlled flexible automatic processing line for graphite electrode connector that can satisfy electrode contact processing special requirement is proposed.
Further aim of the present invention is: the improvement design by to conveying device, a kind of workpiece transfer, convenient mounting and clamping are proposed, and the fully numerically-controlled flexible automatic processing line for graphite electrode connector of compact conformation, thereby help to improve automatization level.
In order to reach above primary and foremost purpose, fully numerically-controlled flexible automatic processing line for graphite electrode connector of the present invention comprises control system, and respectively by the following special purpose machine tool of the driven by servomotor that is controlled by control system:
A. electrode contact cutting-off machine;
B. numerical control electrode joint planar end surface, drill centers lathe;
C. two outer cone lathes of numerical control electrode joint;
D. the two screw threads of numerical control electrode joint are combed machining tool;
E. the numerical control electrode joint bores keyhole, dress bolt, groove milling lathe;
Above lathe is connected by conveying device, forms processing line; It is characterized in that: described control system comprises a central controlled master control system and at least one special purpose machine tool control system of control separately, the downstream of described special purpose machine tool control system links to each other with the electrical equipment of corresponding special purpose machine tool by control circuit, and its upstream links to each other with the corresponding port of master control system by input/output interface module.
Like this, on the one hand, when processing graphite electrode nipple in enormous quantities, both can monitor every equipment of processing line, can control adjustment to special purpose machine tool by the special purpose machine tool control system again by master control system, very convenient; On the other hand, process the graphite electrode nipple of a small amount of special requirement when needs, when perhaps needing to call certain special purpose machine tool temporarily, can avoid master control system, directly at this special purpose machine tool place, debugging special purpose machine tool control system gets final product separately, thereby obviously strengthens the adaptability of processing line, makes its flexibility more.
In order to reach further purpose, conveying device of the present invention is made up of the electric control system that is supported on waggon, the open-close type manipulator on the gantry frame and can sends location of workpiece signal, and described manipulator is installed on the waggon by lowering or hoisting gear.
When processing line of the present invention moves, after the manipulator holding workpiece on the conveying device, raise up, be transported to the special purpose machine tool place that needs clamping workpiece, and send relative position signals, fall workpiece again.After treating clamping workpiece, processing, again by the manipulator clamping, promote, be transferred to next special purpose machine tool, carry out the following process operation.The rest may be inferred, until finishing whole process.No matter compare with existing platform-type conveying device, be that the lifting of workpiece is shifted, and still control is all more flexible automatically, and the clamping of workpiece overlaps with Working position, and floor space obviously reduces.
Description of drawings
The invention will be further described below in conjunction with accompanying drawing.
Fig. 1 is the structural representation of one embodiment of the invention.
Fig. 2 is the structured flowchart of control system of the present invention.
The specific embodiment
Embodiment one
