Description
Technical field
The present invention relates to a kind of thread machining device, the non-rotary anchor head screw thread process dress of particularly a kind of overlength drag-line
Put.
Background technology
As national basis build the increasing of dynamics, various large-scale bridge constructions are more and more, and new entirety is squeezed
Pressure type guy of twisted steel cable is substantial amounts of to be applied in modern bridge construction, and monolithic extruded formula guy of twisted steel cable can be produced at present
Producer only two at home, present applicant is exactly wherein one.
Limited by the structure of this drag-line, the regulation screw thread of steel for wire drawing be after whole drag-line carries out extrusion process again
Processing, the screw thread process of current anchor head mainly has 2 kinds of modes, and one kind is that drag-line is loaded onto into lathe, directly spiral shell on lathe
Out, also a kind of processing method is that a set of frock that tooth is opened similar to water pipe is filled on the main shaft of lathe to whim, is processed
Screw thread.The processing cost and difficulty of processing of both processing methods is all higher.
First method, drag-line is mounted on lathe and processes：When screw thread is processed, drag-line needs the main shaft through lathe
Hole clamps, and drag-line must all release, straighten, and corrects, and no matter how long drag-line has, it is necessary to rotation is carried out under drag-line
Support, when cutting thread, drag-line must rotate, and some guy cable lengths are more than 50 meters or even longer, are required for supporting, and protect
Card drag-line is straight, and otherwise drag-line rotation can be difficult.So process, take very much in the clamping process of drag-line, a length 50
The clamping of drag-line more than rice even needs several hours.And drag-line needs good dynamic balancing in rotary course, otherwise
So long drag-line has very big eccentric force rotating, and can get rid of from bracing frame, thus can only slow-speed of revolution rotation
Turn processing, efficiency is very low.
Also a kind of processing method is that drag-line is mounted in the other end of lathe, and a rotation is filled in the live spindle of lathe
Cutter head, similar to water pipe the frock of tooth is opened, and drag-line is fixed, and is rotated by the forming cutter in frock, and to steel for wire drawing spiral shell is carried out
Line is processed, and as with screw die processing screw thread, only forming cutter frock is the plate of activity to the principle of this frock processing screw thread
Tooth, the size opened by adjusting threading die forming cutter is processing screw thread.Forming cutter is first adjusted before processing（Generally 3）,
The depth opened, it is ensured that the depth of cutting at one time, is processed to steel for wire drawing, and anchor head is rotated by fixed speed, by shaping
Knife plate goes out screw thread, and, all than larger, some have 12mm for the pitch of steel for wire drawing, when half depth is worked into, forming cutter
Cutting zone becomes big, and processing will become very painstaking, because frictional force is big, forming cutter is very easy to fracture, thus can only it is little enter
Knife amount is processed.Efficiency is very low, and forming cutter expensive, and a set of knife needs thousand of yuan, and operative upper one
The little error of point often causes thousand of yuan of knife to scrap.If collapsing knife in process, lathe can not enter in rotation
Withdrawing, it is impossible to stop at once, needs operator to shut down, otherwise continues to process, and also anchor head can be damaged, and may report
Destroy whole drag-line.This plus formula mode requires operator very high.
The content of the invention
The technical problem to be solved in the present invention is：There is provided drag-line in a kind of process need not straighten, and directly disk can exist
On rope disk, the accuracy of thread that processes is high, high in machining efficiency, require operator the non-rotary anchor head spiral shell of low overlength drag-line
Line processing unit (plant), to solve the problems, such as that difficult processing, high processing costs, working (machining) efficiency be low, crudy is poor.
