Machine of drawing of 3.5t copper pipe technical reformation

Car of machine of drawing of single track of 5t odd catenary walks slideway and car walk the problem that the orgnaization exists, use a variety of transforming method, favorable result is achieved after carrying out. The graph in technical reformation of problem of keyword drawing engine classifies date TG355.

3 document label piles up B one, club of limited company canal distributes material of copper of group of overview river copper the factory is one has marvellous processing factory of the copper pipe that produces per year ability of 10 thousand T, copper. Technology division shares its drawing to arrive from 20t 0.

5t measurement is different the drawing machine of tonnage 15. The finished product norms of drawing is φ 25mm × 1.

5mm copper pipe, when drawing with 3mm of φ 46mm × crowded make a canal regard a canal as base. Pass 3 drawing working procedure in all to finished product from drawing tubal semifinished product, dimension of drawing of two intermediate working procedure is φ 38mm × 2.

5mm and 2mm of φ 32mm × , pull φ 25mm × finally 1.

5mm, next, via straightening machine put in storage of Jiao Zhi hind is sold. If require production,compare φ 25mm × 1.

5mm is smaller the product of norms (× of 9mm of 1 Mm of 1 Mm of × of the 18mm that be like φ , φ 16mm × , φ 0.

75mm) when, criterion with φ 25mm × 1.

5mm is pulled via 3 drawing working procedure again for preform make place want a product. In drawing process, with 3.

Working load of susceptive of 5t drawing machine the time of the biggest, actuate is the longest, decisive effect is having in drawing exercise working procedure, the stand or fall of its function has major effect to exercise efficiency. Factory of cent tubal a club 3 TL-3.

5 model 3.

Course of 5t drawing machine is used for years, the car on its lathe bed walks slideway wears away badly already, the car walks the orgnaization has more drawback, affect productivity severely, to solve this one problem, undertake technical reformation to this drawing machine. 2, the problem canal club of existence divides factory TL-3.

5 model 3.

5t drawing machine is local sketch map is shown 1 times like the graph, section sees a picture 2. This model drawing machine car contains walk annulus, cincture and hang annulus. Walk slideway makes round of edge machine tool the level is mobile, car of edge wheel pair has fixed position on horizontal way, in making the car keeps right, hang wheel pair car to be in perpendicular up fixed position has on direction, make car automobile body maintains a level. With 3 kinds the bearing of different type regards this as 3 kinds of wheels directly, bearing is contacted with slideway directly, allow easy damage, especially cincture and hang round of attaint the most frequent. Graph 1 graph 2 this model drawing machine uses flank drawing, flank to fall stuff kind undertakes to copper pipe drawing is machined (graph 3) , knock against of the copper pipe that the advantage of means of this kind of drawing depends on can avoiding drawing to go out and transmission catenary, slideway and cut surface. But, get in drawing process the action of moment of couple, cincture allows easy damage. Additional, because the car gets traction of transmission catenary drawing up action, hang round of likewise easy attaint. In addition, drawing machine car walks slideway flank wears away easily. When slideway two lateral wear extent reachs fair numerical value when, can make line of car gate center and drawing model the deviation value of central line is too great, the flexibility that brings about the copper pipe that drawing gives then passes big or copper pipe ruptures in the generation in drawing process. Nextpage pursues 3 3, transform measure to carry thorough analysis, research, the decision undertakes following technical reformation (transform around graphic representation to refer to a graph 2, graph 4) . Graph 4 1. The car walks slideway transforms original machine tool to serve as lathe bed and slideway with channel and armor plate, serve as lathe bed with 25# I-steel now, increase the board that fills up 50mm of × of 220mm of 8 280mm × on lathe bed bracket, make the height of lathe bed bracket increases appropriately, in order to satisfy the high requirement of new setup lathe bed, slideway. In I-steel two side solder highly appropriately certainly the seamless steel tube that norms is 9mm of φ 50mm × each one, walk as the car slideway, of I-steel on the transmission catenary that installs inside groove guides groove still is used old. 2. The car walks the orgnaization transforms a design, make the appearance that contacts a part with new guide identical circular arc curve gyro wheel, replace former car to walk the orgnaization walks mediumly annulus, cincture and the intention of 3 kinds of position that hang wheel pair car, reduce the sort of wheel thereby, lower fault rate. The gyro wheel of new design, can pass gyro wheel the adjustment that go up bolt will adjust the clearance between gyro wheel and slideway. The car walks after the orgnaization is installed, want to adjust 4 gyro wheel, make the clearance between gyro wheel and slideway agrees basically, in making a car basic standard, right. With drawing model the center is fiducial, go further adjust 4 gyro wheel, make the car maintains a level, make car gate central line and drawing model central line keeps consistent. Try play copper pipe and fine tuning 4 gyro wheel, ask till can contented production till. 4, transform the effect 1. The fault rate of equipment has before reducing machine down time of breakdown of annual of 3 drawing machine apparently to improve, control for 540h, 146h left and right sides is after improving, reduced 394h, annual breakdown machine down time falls amount to 73% . 2. Before spare parts wastage has the apparent spare parts cost that reduces annual of 3 drawing machine to use up to improve, be about 5.

90 thousand yuan, after improving, be about 1.

10 thousand yuan, charge of annual and spare spare parts is made an appointment with 4.

80 thousand yuan. 3. Productivity has bigger because equipment fault rate drops considerably,rise, the can be used at production time that makes annual of 3 drawing machine increases is 394h left and right sides, thereby, make the productivity of drawing working procedure had relatively substantially rise. 4. The φ 25mm × of the production after the quality of copper pipe has clear improvement to improve 1.

The flexibility of 5mm copper pipe reduces 7mm/m by 15mm/m, and put an end to copper pipe to rupture mediumly in drawing process phenomenon. Classics of 3 drawing machine after technical reformation, can produce × of T2 φ 25mm every year more 1.

196t of 5mm copper pipe is controlled, can increase profit every year more 25.

480 thousand yuan or so. CNC Milling CNC Machining
