Description

A kind of manufacture method of flange slide block blank section bar
Technical field
The present invention relates to flange slide block blank section bar in linear rolling guide manufacture method.
Background technology
Slide block is the important component of linear rolling guide.Slide block blank section bar is that rolling linear guide is produced indispensable raw material.Slide block material therefor is roller bearing steel (GCr15), is a kind of special high-carbon alloy steel.Its main feature is: high strength, high rigidity, high-wearing feature.From the angle of section bar manufacture, its phosphorus content is high, and intensity is high, and plasticity is poor, is difficult to Accurate Shaping.In slide block manufacture process, there is strict heat treatment requirements, raw-material spherodized structure structure is had to very high requirement, must reach 3 grades of nodularization standards.Traditional slide block blank product moulding technique is hot rolling or heat extrusion forming.Its major defect: 1, forming temperature is high, raw material institutional framework is uncontrollable.2, section bar intermediate groove cannot put in place in moulding, and stock utilization is only more than 62%.3, blank section bar precision is low, and surface quality is poor, and allowance is large.4, the bending and the torsional deformation that in product moulding process, produce are large, and continuous difficulty of processing is increased.5, the oxide skin producing in follow-up spheroidizing process, can only pass through bead, has increased follow-up production cost.
Summary of the invention
For above problem, the object of the present invention is to provide a kind of manufacture method of flange slide block blank section bar, to be shaped and to make a kind of surface aesthetic through hot rolling, slightly cold drawn, annealing, cold drawn, spheroidizing, finish draw finish draw with stock of square, tissue is desirable, the flange slide block blank section bar that hardness is moderate.
Technical scheme of the present invention is achieved in the following ways: a kind of manufacture method of flange slide block blank section bar, is characterized in that: comprise the following steps:
1), stock of square hot rolling: the GCr15 square bar blank being of the required size is heated to 1200 DEG C in hot rolling stove, through hot rolling line Shang 10 road rolling rolls, between each rolling roll, form 10 kinds of hole shapes, the square steel billets having heated is respectively through K1, the each hole shape rolling of K2, K3 to K10, shut out the hot blank of hot rolling blank section bar, after naturally cooling, reach size and material inside organization requirement of rolling the cold steel of blank brimful of tears;
In described course of hot rolling, the temperature of hot rolling blank is controlled at 850~900 ° of C.
2) slightly cold drawn: rough surplus is determined by cold-drawing process equipment and roll process, is 0.3-1.0mm.
3) annealing: homogeneous heating to 830~850 ° C, cooling with stove;
4) cold drawn: be the preform stage of finish draw, finish draw surplus is 0.3~0.5mm;
5) spheroidizing: by blank homogeneous heating to the 800~810 ° C after cold drawn, be incubated 5 hours; Be cooled to 710~760 ° of C, then be incubated 4~5 hours, cool to 550 ° of C with the furnace, the air cooling of coming out of the stove;
6) finish draw is shaped: finish draw forming workblank surplus is 0.3~0.7mm.
Advantage of the present invention: 1). forming temperature is lower, and raw material institutional framework is easily controlled, and there will not be superheating phenomenon.2). section bar intermediate groove basic forming puts in place, and the non-face that adds of profile is completely shaped and puts in place, and polished surface only stays 0.3mm surplus.Reach more than 72.7% to the stock utilization of completion finished product from blank section bar.3). blank section bar precision is high, and surface roughness reaches 1.6, and allowance is little, only has 0.3mm.4). the bending that section bar produces in course of hot rolling and torsional deformation can effectively be proofreaied and correct in cold drawing process.Make in continuous batch production process, sawing machine blanking efficiency improves 3 times, and size can accurately be controlled, and reduces the follow-up surplus that adds; The efficiency of double end milling machine improves 50%, and the efficiency of thick plain grinding improves 30%.The processing cost that effectively reduces subsequent production link, has also improved stock utilization simultaneously.5) oxide skin producing in spheroidizing process, removes totally completely in finish draw process, has reduced follow-up surface-treated cost.6). guarantee that spheroidizing reaches 3 grades, prepare for subsequent heat treatment operation performs tissue.

Detailed description of the invention
Known by Fig. 1, to produce 25 flange slide block blanks as example, comprise the following steps:
1, stock of square hot rolling: the GCr15 square bar blank being of the required size is heated to 1200 DEG C in hot rolling stove, through hot rolling line Shang 10 road rolling rolls, forms 10 kinds of hole shapes between each rolling roll; The square steel billets having heated, respectively through K1, the each hole shape rolling of K2, K3 to K10, shuts out the hot blank of hot rolling blank section bar, reaches size and material inside organization requirement of rolling the cold steel of blank brimful of tears after naturally cooling; In described course of hot rolling, the temperature of hot rolling blank is controlled at 850~900 ° of C.See shown in Fig. 2-Figure 11.
2, slightly cold drawn: rough surplus is determined by cold-drawing process equipment and roll process, is 0.3-1.0mm.
