Abstract
By using steel billet, waste steel rail or left-over as material and through the technological steps of heating, rolling into band, punching, ausforming and grinding or the technological steps of heating, hot rolling to form, ausforming and grinding, blade for farm machine is manufactured. The ausforming before grinding makes the produce possess high strength, high plasticity and high toughness. The simple technological process can produce product with high quality and long service life.
Description
What the present invention relates to is the manufacture craft of the blade that uses on the agricultural machinery equipment.
Blade such as harvester blade that agricultural equipment uses, blade for stubble ploughing machine etc. are consumable accessory, need often to change, and consumption is quite big.Its manufacture craft more complicated, be example only with the harvester blade, it is to be raw material with valuable T9A or 65Mn flat cold-rolled sheet, after cutting into the bar shaped material on punch press blanking, punching and smoothing dig the inclined-plane, both sides then on planer, by milling machine the inclined-plane is milled out groove again, also will be by behind the high-frequency quenching, the correct grinding bottom surface forms on grinding machine.Numerous with the blade operation that this method is made, the cost height, of poor quality, the life-span is short, and energy consumption is big and time-consuming, and is bothersome.
The object of the present invention is to provide a kind of technology simple, with low cost, reduce energy consumption, increase service life, the manufacturing technology of the blade of farm machine of saving trouble and can effectively improve the quality of products of saving time.
The solution of the present invention is as described below: this invention is that to adopt steel billet or useless heavy rail or inferior horn be raw material, heat by raw material successively, rolled steel strip, blanking and punching, thermomechanical treatment, grind finished product or by raw material heating, hot rolling (die forging) moulding and thermomechanical treatment, grind that the processing step of finished product realizes.
The present invention is owing to taked thermomechanical treatment once to finish processing inclined-plane, groove with quenching technical or once become hot rolling (die forging) moulding and thermomechanical treatment, and blanking of the prior art, punching two procedures changed into a procedure and finish, the combination of other operation in addition, it is simple to make this invention not only have technology, advantages such as easily manufactured, cost is low, and energy consumption is little, and in manufacturing process the situation of no cutting metallic fiber, thereby can improve the inherent quality of product.Particularly taked to grind the preceding thermomechanical treatment of finished product, pressure processing has been combined the superiority of having given full play to comprehensive utilization working hardening and phase transformation strengthening with heat treatment phase, made product have high strength, high-ductility and high tenacity.And when simplifying product process flow, improved product quality, prolong service life, and made things convenient for the user.
Accompanying drawings embodiment:
Fig. 1 is a harvester blade process chart in the blade of farm machine manufacturing technology;
Fig. 2 is stubble cleaner in the blade of farm machine manufacturing technology (rotary cultivator) blade process chart.
The harvester blade that the present invention is made by technology shown in Figure 1, should take lower steel billet of price or useless heavy rail is raw material, making thin steel band after raw material heating 1 on rolling mill is rolled steel strip 2, to approach steel band sends into punch press and carries out blanking and punching 3, make semi-finished product through blanking and punching 3, implement thermomechanical treatment 4 with flame or eddy-current heating then, once finish inclined-plane, blade both sides, the processing of groove and quenching, the sharpening bottom surface promptly grinds finished product 5 and gets final product again.
Another embodiment of the present invention is to make stubble cleaner (rotary cultivator) blade by technology shown in Figure 2.Quantitative dosing and raw material heated, is called raw material heating 1 is at first sent into the rolling mill hot-roll forming then and is taked flame heat or eddy-current heating to implement thermomechanical treatment simultaneously promptly to be rolled into type and thermomechanical treatment 2, to finish through grinding finished product 3.This invented technology is simple, and cost of material is low, and energy consumption is few, and economic benefit is considerable, makes things convenient for automated production, and can utilize this invention to manufacture other various blade of farm machine.
Claims (3)
1, a kind of manufacturing technology of blade of farm machine is characterized in that: this technology is successively by raw material heating (1), rolled steel strip (2), blanking and punching (3), thermomechanical treatment (4) and grind the processing step realization of finished product (5).
2, the manufacturing technology of blade of farm machine according to claim 1 is characterized in that: this technology also can heat (1), hot rolling (die forging) moulding and thermomechanical treatment (2) by raw material, grind finished product (3) processing step finishes.
