Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation:
Fig. 1 is the structural representation of the heavy lifting of the embodiment of the invention with the hoop chain monocycle;
The mark of each parts is following in the accompanying drawing: 1, left semi-ring, 2, right semi-ring, 3, sclerotin alloy steel core.
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 structural representation of the heavy lifting of the embodiment of the invention with the hoop chain monocycle; This hoop chain comprises an oval ring main body; Described oval ring main body is made up of with right semi-ring 2 left semi-ring 1; Left and right semi-ring is realized being connected through welding procedure, and described left and right semi-ring adopts casting technique to prepare separately, and its material of main part is a high-strength wear-resistant alloy; Establish annular sclerotin alloy steel core 3 in the described left and right semi-ring, this sclerotin alloy steel core 3 can effectively improve the intensity of hoop chain.
The heavy type lifting of mentioning among the present invention uses the main component and the percentage composition thereof of its left and right semi-ring of hoop chain to be: Fe 85%-90%, C 2.5%-3.5%, Ni 3.5%-5%, Si 0.5%-1.5%, Mn 1.2%-1.5%, Al 1.5%-2.5%; Left and right semi-ring adopts sand casting process to prepare, and wherein, molding sand is formed by silica sand, resin and hardening agent mixed preparing, and resin is selected alkalescent phenol resin for use; The pouring temperature of liquid alloy is controlled at 1600 ℃-1620 ℃.
Sclerotin alloy steel core 3 materials and percentage composition thereof in the left and right semi-ring are: Fe 80%-85%, Mn 12%-18%, C 0.4%-0.6%, Ti 1.2%-1.5, Cr 6%-8%; Sclerotin alloy steel core 3 is the semicircular ring structure, with the volume ratio of hoop chain semi-ring be 1:30, this sclerotin alloy steel core 3 can make the intensity of hoop chain improve more than 30%.
Preparation method's concrete steps of this hoop chain are following:
A) sand mold manufacturing, molding sand mainly are to be formed by silica sand, resinoid bond and hardening agent mixed preparing, and wherein, the granularity of silica sand is the 60-100 order, and resin is selected alkalescent phenol resin or resol for use, and hardening agent is selected ferrosilicon powder for use; Three's mixed proportion is about: silica sand 75%-80%, resinoid bond 15%-20%, hardening agent 5%-8%;
B) preparation steel core, steel core selects for use the composition of alloy material and percentage composition thereof to be: Fe 80%-85%, Mn 12%-18%, C 0.4%-0.6%, Ti 1.2%-1.5, Cr 6%-8%; Mainly through casting and Forging Technology moulding, steel core has high hardness to this steel core, can effectively improve the intensity and the impact resistance of hoop chain; The steel core that makes accounts for the 3%-4% of hoop chain total volume, can make the intensity of hoop chain improve more than 30%;
C) alloy cast before the alloy cast, needs steel core is imbedded the sand mold inner chamber, and fixes through arbor, makes steel core be positioned at the whole middle part of sand mold, gives full play to the effect that steel core is strengthened chain link; Pouring into a mould used alloying constituent and percentage composition thereof is: Fe 85%-90%, C 2.5%-3.5%, Ni 3.5%-5%, Si 0.5%-1.5%, Mn 1.2%-1.5%, Al 1.5%-2.5%; Alloy raw material after fully grinding, heating and melting, melt temperature is controlled at 1650 ℃-1680 ℃, the pouring temperature of molten alloy is controlled at 1600 ℃-1620 ℃, poring rate is 15mm/s;
D) cooling and shaping, die sinking is placed on and carries out slow cooling in the stove after taking out foundry goods, and Control for Kiln Temperature is at 40 ℃-60 ℃, and be 1-2 hour cool time; Slow cooling helps reducing the probability of alloying constituent generation segregation in the chain link in the stove, makes alloying constituent more well-balanced, and effect is able to give full play to, and this type of cooling helps further stablizing the size of chain link simultaneously, for follow-up chain loops welded is carried out preparation;
E) remove feeders; On grinding machine, the moulding chain link is repaiied type and polishing processing; This operation is mainly used in removes the cutting-off gate that on chain link, forms in the casting technique implementation process, and polishing processing is carried out in the chain link end, and deburring is to improve the welding performance of chain link end;
F) welding chain link, the welding procedure that chain link adopted is the preheating flash welding, this manufacturing process comprises: once flash of light, The pre-heat treatment, secondary flash of light and upset; Wherein, once the purpose of flash of light is the chain link end face to be dodged put down; In advance the method handled of method is for connecting the flash of light preheating, and two chain link faces alternately slightly contact and separate in the group flashing light preheating implementation process, send interrupted flash of light and realize preheating, and preheating temperature is about 1450 ℃; Secondary flash of light and blocking 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; Wherein, temperature is 1350 ° of C before the upset, about 1050 ℃ of-1100 ° of C of postwelding temperature;
G) go out deburring, after welding finishes, use the removal of hydraulic pressure deburring device to make and be soldered on the chain circumferential weld because the burr that extruding is produced;
H) Checking of finished products.
The present invention has disclosed a kind of heavy lifting and use hoop chain, is characterized in: this hoop chain scientific structure design, one-tenth assignment system are reasonable, and preparation process is easy, and cost is moderate, and it is good to have a good comprehensive mechanical property; Especially lead over like product in the performance that is shown aspect intensity and the anti-impact force, make that hoop chain is in use more reliable, safety, be particularly suitable for allocating and transporting heavy goods.
The above; Be merely 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.
