Abstract
The utility model provides a steel for the blades of stubble cleaners, which is a deformed steel used for manufacturing the blades of stubble cleaners. The utility model is formed by that one side of a bar-shaped flat steel (2) is provided with an inclined plane (1), and the bottom of the side without the inclined plane (1) of the bar-shaped flat steel (2) is lengthways provided with a groove (4). Compared with the steel for the blades of stubble cleaners whose one side is provided with intermittent inclined planes, the utility model can save steel by 18%. Compared with the steel for the blades of stubble cleaners whose one side is provided with inclined planes fully, the utility model can save steel by 6%. The utility model has the advantages of simple manufacturing technique, balanced extensibility, flat and straight product, high abrasion resistance, convenient operation, etc.
Description
The utility model relates to a kind of special section, particularly relates to a kind of used special section of blade for stubble ploughing machine of manufacturing.
A few days ago by the blade for stubble ploughing machine steel of explained hereafter such as hot rolling, roll forging, be that a side at band steel is provided with the inclined-plane evenly, discontinuously and two kinds of razor steel structures on inclined-plane all are set in a side of band steel.Be interrupted the razor steel conservation that the inclined-plane is set although a side all is provided with the razor steel on inclined-plane than a side, the both sides percentage elongation of above-mentioned two kinds of razor steels is all uneven, easily produces bending when tiltedly making, thereby influences product quality.
The purpose of this utility model is will provide a kind of and not only economized in raw materials, but also can make both sides percentage elongation balance, and the product of making is not crooked and straight, the blade for stubble ploughing machine steel that quality is better.
The purpose of this utility model is achieved in that this utility model comprises that a side is provided with the bar shaped band steel on inclined-plane, along it groove is set vertically in the bottom near this bar shaped band steel slope-less one side.Its groove can according to circumstances be made arc, brachmorphy or structure such as trapezoidal.
The utility model is owing to the bottom that is provided with the bar shaped band steel on inclined-plane in a side is provided with groove, not only can be interrupted the blade for stubble ploughing machine steel that is provided with the inclined-plane and save steel 18% than a side, the blade for stubble ploughing machine steel that is provided with the inclined-plane than a side is saved steel 6%, and it is simple to have manufacturing process, and the percentage elongation balance, product is straight, wearability is strong, advantage such as easy to use.
Accompanying drawings embodiment:
Fig. 1, Fig. 2, Fig. 3 all are cross-sectional structure schematic diagrames of blade for stubble ploughing machine steel.
By Fig. 1---blade for stubble ploughing machine steel shown in Figure 3 is the bar shaped band steel 2 that is provided with the inclined-plane in a side to be constituted near the bottom of a side 3 of its slope-less 1 groove 4 that vertically is provided with along this bar shaped band steel 2.This groove 4 can be arc, rectangle or structure such as trapezoidal.
This utility model is through the hot rolling one-shot forming.Can intercept arbitrarily by Len req when manufacturing blade.Not only economize in raw materials but also convenient.
Claims (2)
1, a kind of blade for stubble ploughing machine steel comprises that a side is provided with the bar shaped band steel (2) on inclined-plane (1), it is characterized in that the bottom of a side (3) of this bar shaped band steel (2) slope-less (1) is provided with the groove (4) that vertically is provided with along it.
2, blade for stubble ploughing machine steel according to claim 1 is characterized in that groove (4) can be arc, rectangle or trapezium structure.
