Abstract
The invention provides a once forming fabrication technology of a die forging crane wheel, which comprises the steps of heating steel, oxidizing, entering a forming die, conducting blanking on the steel with a numerical-control horizontal sawing machine, allowing the steel to enter a heating furnace, heating the steel to be about 1200 DEG C, allowing the steel to be discharged from the furnace, removing oxide skins with a high-pressure water gun, entering the forming die directly, fabricating and forming all structures except wheel grooves and a shaft hole within 30 seconds with a megaton forging machine, accomplishing upsetting, returning to the furnace for heating, and entering the die. The technology adopts the technical scheme that with the adoption of the advanced technology, the production procedures can be decreased, the production cost can be lowered greatly, and the production efficiency can be improved greatly.
Description
Technical field
The present invention relates to a kind of crane locomotive wheel production Technology.Especially can the first mate reduce production costs and enhance productivity.
Background technology
Present domestic die forging crane locomotive wheel production technology all needs post bake and wheel race to be shaped in forging process, its technological process of production mostly be blanking, heating, pier slightly, heating, descaling again, go into die forming, punching, heat treatment, trimming, go into roughcast warehouse, roughing, modified, fine finishining, finished product warehouse-in, have in addition also need three heating.This just certainly will cause, and production cost height, efficient are low etc. to be unfavorable for that producer and user are competing in current intense market competition.
Summary of the invention
In order to overcome in the existing technological process of production production cost height, the inefficient deficiency that heating again and roughing cause, the invention provides a kind of production Technology, this technology can not only reduce production process, also can significantly reduce production costs and significantly enhance productivity.
Based on above-mentioned purpose, technical problem solved by the invention realizes by the following technical solutions:
A kind of preparation technology of die forging crane wheel once-forming, step of preparation process of the present invention is:
1) steel heating, oxidation, enters shaping dies; Steel are come out of the stove after utilizing the laggard heating furnace of numerical control horizontal sawing machine blanking to be heated to about 1200 ℃, utilize after the giant descaling directly into shaping dies, utilize ten thousand tons of forging presses in 30 seconds, the structure except wheel race and axis hole all to be made shaping, finish jumping-up, melt down heating, go into mould;
2) roller groove, roughing, fine finishining; Utilize the milling train roller groove after going out shaping dies, finish the operation that needs process roughing just can finish in the traditional handicraft in 120 seconds, namely crane wheel race is shaped and also keeps 3-5mm allowance so that modified back fine finishining;
3) towards axis hole, heat treatment; The crane wheel all is shaped behind the axis hole, advances heat-treatment furnace and carries out the formation that positive temper suppresses the inside wheel net carbide and eliminate internal stress, to obtain the good interior tissue of wheel and to improve its toughness;
4) warehouse-in, modified, fine finishining, check, warehouse-in again; After the wheel modulation, further carry out the blank warehouse-in, carry out, after modified, the check, enter warehouse for finished product.
The technical scheme that the present invention has done has adopted advanced technology, and this technology can not only reduce production process, also can significantly reduce production costs and significantly enhance productivity.

The specific embodiment
Below by Figure of description, further set forth the present invention;
According to Fig. 1, Fig. 2, shown in Figure 3, steel are come out of the stove after utilizing the laggard heating furnace of numerical control horizontal sawing machine blanking to be heated to about 1200 ℃, utilize after the giant descaling directly into shaping dies, utilize ten thousand tons of forging presses in 30 seconds, the structure except wheel race and axis hole all to be made shaping, finish slightly, melt down heating, go into mould; Utilize the milling train roller groove behind the shaping dies, finish the operation that needs process roughing just can finish in the traditional handicraft in 120 seconds, namely crane wheel race is shaped and also keeps 3-5mm allowance so that modified back fine finishining; The crane wheel all is shaped behind the axis hole, advances heat-treatment furnace and carries out the formation that positive temper suppresses the inside wheel net carbide and eliminate internal stress, to obtain the good interior tissue of wheel and to improve its toughness; After the wheel modulation, further carry out the blank warehouse-in, carry out, after modified, the check, enter warehouse for finished product; The car wheel structure of final once-forming comprises race 1, axis hole 2, technology groove 3, wheel face 4, fabrication hole 5.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
