Background technology
At mechanical processing industry, machining center all is to adopt round steel to forge into earlier slab with the processing of accurate line slideway slide, forms through metalworking more at present.Can process the guide rail slide though adopt to forge, have following problem with metalworking: the one, the production cycle is long, and efficient is low; The 2nd because need metalworking, to consume steel many, forge to heat, to waste energy many, therefore, adopt this method, production cost is higher.
Summary of the invention
The problem to be solved in the present invention provides the production method of a kind of machining center with accurate line slideway slide.Adopt this method production and processing center with accurate line slideway slide, the efficient height, production cost is low.
For addressing the above problem, take following technical scheme:
Machining center of the present invention is to may further comprise the steps successively with the production method characteristics of accurate line slideway slide:
(1) hot rolling
With cross-arranging type hot rolling unit, under the milling train rotating speed of 2.4 ~ 2.6 meter per seconds, 1100 ~ 7900 ℃ rolling temperature, round rolling is become similar parison;
(2) spheroidizing
Earlier similar parison is dropped into temperature and be in 780 ~ 790 ℃ the annealing furnace, be incubated 3～4 hours again behind the samming; Afterwards, under≤10 ℃/hour cooling rate, the temperature of annealing furnace is reduced to 745 ~ 755 ℃, and under this temperature, continue to keep 2 hours; Afterwards, under≤9 ℃/hour cooling rate, the temperature of annealing furnace is reduced to 715 ~ 725 ℃, and under this temperature, continue to keep 1.5 hours; Again, under＜9 ℃/hour cooling rate, the temperature of annealing furnace is reduced to 645 ~ 655 ℃, open fire door, will be through the similar parison cools of spheroidizing to normal temperature;
(3) dog
Under the milling train rotating speed of 0.5 meter per second, will match with the drawbench bare terminal end so that pass mould through the similar parison one termination portion pointing of spheroidizing;
(4) pickling
With temperature is that 55 ~ 65 ℃, concentration are that the sulfuric acid solution of 8 ~ 12 weight % cleans the similar parison of handling through dog, removes oxide layer;
(5) phosphatization is handled
To put into concentration through the similar parison that cleaned is that 4 ~ 7 weight %, temperature are 50 ~ 70 ℃ phosphatization liquid, and constant temperature kept 10 ~ 20 minutes, carries out phosphatization and handles;
(6) saponification is handled
To put into concentration through the similar parison that phosphatization was handled is that 8 ~ 12 weight %, temperature are 58 ~ 63 ℃ saponification liquor, keeps 5 ~ 7 minutes, carries out saponification and handles; Wherein, the content of aliphatic acid is 50 ~ 80 grams in the saponification liquor;
(7) cold-drawn
With drawbench and mould, will become the slide base through the similar parison cold-drawn that saponification was handled with 8 ~ 12 meters/minute speed;
(8) intermediate annealing
It is in 690 ~ 710 ℃ the annealing furnace that the slide base is dropped into temperature, and constant temperature kept 6.9 ~ 7.1 hours; Afterwards, stop to heat, cooling was opened fire door after 2 hours in annealing furnace, naturally cooled to normal temperature with air;
(9) aligning
Use straightener, the slide base of annealed processing is aligned, obtain the semi-finished product base with 40 meters/minute speed;
(10) cutting
With sawing machine the semi-finished product base is cut, obtain machining center with accurate line slideway slide.
Take such scheme, have the following advantages:
By such scheme as can be seen,, first round steel is rolled into similar parison,, need forge and metalworking, can enhance productivity greatly again through cold-drawn and moulding is compared with background technology because the present invention combines with cold-drawn with hot rolling.Owing to do not need metalworking, steel obtain maximum using, thereby have saved steel again.In addition,, do not need repeatedly workpiece to be heated, can save the energy owing to need not forge.Therefore, adopt the present invention, can reduce production costs.
