Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is done further detailed explanation:
Fig. 1 is the preparation method's of the novel round-link chain of the embodiment of the invention process figure.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
Fig. 1 is the preparation method's of the novel round-link chain of the embodiment of the invention process figure; This preparation method comprises the steps: a) to forge half chain link, b) strengthens cleaning, c) chain loops welded, and d) burr are handled, e) Ageing Treatment.
Embodiment
These preparation method's concrete steps are following:
A) forge half chain link, the Forging Technology master operation is: gropping of forging billet, forging stock heating, die-forging forming, side cut, rectification and cooling; Wherein, hot forging equipment is selected fly press for use, and tonnage is 2000-2500KN, and the forging molding time is short, and efficient is high, can realize the single-piece production in enormous quantities; The initial forging temperature of forging stock is controlled at 1150 ℃-1180 ℃, and final forging temperature is controlled at 820 ℃-850 ℃, and forging ratio is 3-3.5; The type of cooling is the air cooling of coming out of the stove after cooling to 450 ℃ with the furnace;
B) strengthen cleaning, half chain link of forging molding also need carry out modified and bead; Wherein, modifier treatment improves welding performance in order to eliminate forging stress, and temperature is controlled at 550 ℃-580 ℃, and tempering time is 1-2 hour; Bead can be strengthened half chain link surface strength and wearability, reduces fatigue, improves service life; In the bead implementation process, the bullet diameter is 0.7-0.8nm, and hardness is 55HRC; Speed is 45m/s, and this processing can effectively improve for half chain link service life more than 30%; Cleaning process mainly is to remove the oxide skin of half chain ring surface, improves its surface quality;
C) chain loops welded, the welding procedure that chain link adopted are the group flashing light weldering, need carry out The pre-heat treatment before this process implementing, and preheat temperature is about 1350 ℃-1400 ℃; Group flashing light and upset operation implementation process are: at first, closed primary circuit slightly contacts two chain link end faces, in the gap of end face, promptly ejects molten metal particulate as the spark; Then, mobile chain link makes both ends of the surface still keep slight contact, forms group flashing light; At last, when flash of light reaches the scheduled time, when two chain link ends nearly are heated to fusing point; Just carry out upset rapidly with certain pressure, when upset is cut off the electricity supply behind certain-length, the technology of welding chain link is promptly accused and is finished; Temperature is 1350 ° of C before the upset, about 1050 ℃ of-1100 ° of C of postwelding temperature;
D) burr are handled, and after the chain loops welded finishes, use the removal of hydraulic pressure deburring device to make and are soldered on the chain girth joint because the burr that extruding is produced improves the chain link surface quality;
E) Ageing Treatment is placed on the oil sealing of finished product chain link and left standstill under the normal temperature 5-8 hour, further stablizes the chain ring size, improves its serviceability.
The present invention has disclosed a kind of preparation method of high novel round-link chain, is characterized in: this preparation method's procedure arrangement is reasonable, and preparation technology is easy; Cost is moderate, and the inboard unique plane boss structure of its arc section designs, and can effectively alleviate the stress concentration phenomenon of round-link chain chain link corner; Reduce the probability that chain link deforms and ftractures; Make the service life of round-link chain more lasting, the allocation and transportation of goods are safer, reliable, guaranteed staff's personal safety.
The above; Be merely the specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
