Abstract
The invention discloses a manufacturing process of a blade of a one-step hot-rolling forming stubble cleaner on an agricultural stubble cleaner. The blade is made of steel billet and through one-step hot rolling to form the blade of stubble cleaner, and high frequency furnace heat treatment to obtain reasonable hardness and optimal transition zone for the handle, cutting edge and back of the blade. When the blade of the stubble cleaner is subjected to hot rolling, the extension width of the blade part is increased by more than 3mm on average, and the blade thickness is 1.0 +/-0.5. The invention has the advantages of low raw material price, simple process, high yield, good product performance and the like.
Description
The present invention relates to a kind of manufacturing process of agricultural stubble cleaner workpiece.
Present existing traditional blade for stubble ploughing machine production is that the expensive sheet material of employing is raw material, at first carry out twice (horizontal and vertical) shearing machine and cut blade, on the crank throw forcing press, extrude upright curved, on drilling machine, get out two holes, on forcing press, extrude flat curved six procedures such as grade at last and finish the blade forming technology that it is begun by sheet material.
The objective of the invention is to provide that a kind of material price is cheap, technology simple, the process for making blade of stubble cleaner by single hot-roll forming of good product performance.
It is raw material with sheet material that the present invention has changed traditional, based on the process of the production blade for stubble ploughing machine of Cutting Process; Replacing steel billet is raw material, adopts and does not have the Cutting Process method less, and promptly single hot-roll forming is produced the process of blade for stubble ploughing machine.The technology of this invention is that steel billet is heated, and once is rolled into basic type (staight shank type) on rolling mill, again through once cutting off punching then and flattening the new technology that four procedures such as curved are finished its blade moulding that is begun by steel billet.Its single hot-roll forming at first on demand size in design on the rolling mill with produce concave groove on the roll and the pass of cooperation.Blade of stubble cleaner by single hot-roll forming has saved plane iron and has pressed upright curved two procedures.During hot rolling blade is extended more than the average 3mm of increase width, sword is thick to be 1.0 ± 0.5mm, and the blade for stubble ploughing machine blade that hot rolling goes out can make metal fibrous tissue continuous, thereby has guaranteed blade and excessively be with toughness.The final heat treatment step that is somebody's turn to do " single hot-roll forming " blade for stubble ploughing machine adopts coreless induction furnace to handle.The imitative type inductor of design segmented in stove makes shank, cutting edge and the knife back obtain the most rational hardness number and best excessively band respectively, and promptly bright the quenching width for HRC40 ± 5, cutting edge HRC52 ± 5, knife back HRC50 ± 5, cutting edge and the knife back is 15mm ± 2mm.This desirable hardness distributes and has improved the rigidity and the toughness of blade for stubble ploughing machine significantly, thereby has prolonged its service life.Adopt " single hot-roll forming " to produce blade for stubble ploughing machine technology, but 1700~1800 blades of one ton of steel billet output, and can produce 1200 blades with one ton of sheet material of cutting method.
The present invention is a raw material owing to selecting steel billet for use, adopts " single hot-roll forming " and coreless induction furnace Technology for Heating Processing to produce blade for stubble ploughing machine, so have advantages such as cost of material is low, production technology simple, finished product rate height, good product performance.
Accompanying drawings embodiment:
Fig. 1 is the process for making blade of stubble cleaner by single hot-roll forming flow chart;
Fig. 2 is the blade of stubble cleaner by single hot-roll forming schematic diagram.
Learn from Fig. 1~Fig. 2: it is raw material that this blade of stubble cleaner by single hot-roll forming adopts steel billet, at first in size design and produce concave groove on the roll and the pass of cooperation on demand on the rolling mill, when producing, earlier steel billet is heated (1), on rolling mill, once be rolled into basic type (staight shank type) (2), through once cutting off (3), curved four procedures such as (4) of punching and flattening are finished then again.During hot rolling blade (5) is extended more than the average 3mm of increase width the thick 1.0 ± 0.5mm of sword.Final heat treatment step adopts coreless induction furnace heat treatment: the imitative type inductor of design segmented, and make shank, cutting edge and the knife back obtain the most rational hardness number and best excessively band respectively, the quenching width of the cutting edge and the knife back is 15mm ± 2mm.
Claims (1)
- A kind of blade for stubble ploughing machine, particularly a kind of process for making blade of stubble cleaner by single hot-roll forming is characterized in that:It is raw material that a, this kind blade adopt steel billet, by steel billet being heated (1), once is rolled into basic type (staight shank type) (2) on rolling mill, and through once cutting off (3), curved (4) four procedures of punching and flattening are finished then again;B, this kind blade increase the average 1.0 ± 0.5mm of width with blade (5) extension when hot rolling;The final heat treatment step of c, this kind blade adopts coreless induction furnace heat treatment, the imitative type inductor of design segmented.
