Description
Technical field
The utility model relates to a kind of thread machining device, particularly the non-rotary anchor head thread machining device of a kind of overlength drag-line.
Background technology
Along with national basis builds the increasing of dynamics, various large-scale bridge construction gets more and more, and a large amount of being applied in modern bridge construction of novel monolithic extruded formula guy of twisted steel cable is gone, the producer that can produce monolithic extruded formula guy of twisted steel cable at present only has two at home, and the applicant of the application is exactly wherein one.
Structure by this drag-line limited, the adjustment screw thread of steel for wire drawing is reprocessed after whole drag-line carries out extrusion process, the screw thread process of current anchor head mainly contains 2 kinds of modes, one is that drag-line is loaded onto lathe, directly on lathe screw thread car out, also have a kind of processing method to be fill a set ofly to be similar to the frock that tooth opened by water pipe on the main shaft of lathe, carry out machining screw.The processing cost of these two kinds of processing methods and difficulty of processing are all higher.
First method, drag-line is contained on lathe and processes: when machining screw, and drag-line needs to clamp through the spindle hole of lathe, drag-line must all be released, and straightens, and corrects, and no matter how long drag-line has, and must carry out rotary support, when cutting thread under drag-line, drag-line must rotate, some guy cable length is more than 50 meters, even longer, all needs to support, guarantee drag-line is straight, otherwise drag-line rotates meeting difficulty.Such processing, very consuming time in the clamping process of drag-line, the clamping of the drag-line of length more than 50 meters even needs several hours.And drag-line needs good dynamic balancing in rotary course, otherwise so long drag-line has very large eccentric force rotating, and can get rid of from bracing frame, so just can only slow-speed of revolution rotation process, efficiency is very low.
A kind of processing method is also had to be other end drag-line being contained in lathe, the rotary main shaft of lathe fills a rotary cutter, be similar to the frock that tooth opened by water pipe, drag-line is fixed, rotated by the forming cutter in frock, carry out screw thread process to steel for wire drawing, the principle of this frock machining screw is the same with by screw die machining screw, only forming cutter frock is movable screw die, and the size of being opened by adjusting threading die forming cutter carrys out machining screw.First regulate forming cutter (being generally 3) before processing, the degree of depth of opening, ensure the degree of depth of cutting at one time, process steel for wire drawing, anchor head rotates by fixing speed, goes out screw thread by shaping knife plate, the pitch of steel for wire drawing is all larger, some has 12mm, and in time being worked into the half degree of depth, the cutting zone of forming cutter becomes large, processing will become very painstaking, because frictional force is large, forming cutter is very easy to fracture, so can only fine feed process.Efficiency is very low, and forming cutter expensive, a set of cutter needs several thousand yuan, and the upper little error of operative often causes the cutter of several thousand yuan to scrap.If collapse cutter in process, lathe can not be retreated cutter in rotation, can not stop at once, need operator to shut down, otherwise continues processing, also can damage anchor head, may scrap whole drag-line.This formula mode that adds requires very high to operator.
Summary of the invention
