Abstract
The present invention relates to a cast steel knife angle which belongs to the technical field of cast formation machining. The present invention is characterized in that the original rolling formation process for producing knife angles is changed into a casting formation machining process, and alloy steel section bar used in the original rolling is changed into high manganese steel materials for casting. Therefore, the process for producing knife angles is greatly simplified. The present invention solves the problem that knife angles depend on imports for a long time, so the present invention has advantages that the cost is greatly reduced, the product performance is greatly increased, service life is prolonged and a large quantity of foreign exchange is saved. Moreover, the production of knife angles is free from the limitation of large batch. A small factory can also produce knife angles, so the history that only a big factory can produce knife angles is changed. The present invention brings a revolution in the history of the production of knife angles.
Description
The present invention relates to a kind of nose angle of casting, belong to the casting processing technique field.
At present, Quan Guogedi bulldozer manufacturer adopts the import section bar to produce the nose angle part by the process of rolling processing.For some bulldozer, as the complete dependence on import of nose angle accessory that the Dgl bulldozer of T220 bulldozer and import etc. uses, domestic can not production, this not only makes the nose angle fetch long price, but also can not solve the difficult problem of the urgent need of production.Our process of using casting instead the technology that replaces roll forming is made the D155A-1A nose angle for this reason, in engineer testing, how to improve the intensity and the abrasion resistance of foundry goods, can its performance requirement that meets the nose angle each side has been become replace the guardian technique difficult problem that roll forming is produced nose angle with casting.
Purpose of the present invention is exactly the design scheme of a kind of D155A-1A nose angle of providing at the technical problem of above-mentioned existence and for the public.This scheme adopts the cast steel material of potassium steel to make the nose angle blank and make the thickness of its thickness a little more than the nose angle section bar by the process of casting, reach and surpass the performance requirement of the D155A-1A nose angle each side of original Rolling Production in the use fully through test, be much higher than the life-span of the nose angle of former Rolling Production its application life, and it is cheap, make the product accessories production domesticization, break away from the situation of dependence on import, solved the urgent need of producing.
The present invention is achieved in that
Shape approximation quadrangle of the present invention wherein has two adjacent limits formation bent angle that upwards turns back, and the angle that bent angle is relative is an acute angle, remain two jiaos and be the obtuse angle, the broken line angle is the right angle, is useful on 7 holes that are connected and fixed at the middle part of nose angle, wherein a row is 4 holes, and a row is 3 holes.Nose angle of the present invention is that its founding materials that uses is high manganese steel material with the ploughshare-like cast steel slash angle of cast shaping process method processing, and the thickness of its nose angle is slightly high than the nose angle thickness that section bar system forms.
Advantage of the present invention is:
(1) adopts the nose angle of casting to replace the problem that the roll forming nose angle has solved the long-term dependence on import of nose angle, the nose angle cost of production is reduced significantly solved the urgent need of producing; (2) adopt cast molding technology to produce nose angle and filled up the domestic blank that can not produce T220 bulldozer and import Dgl bulldozer nose angle, saved a large amount of foreign exchanges; (3) replace rolling nose angle with the casting nose angle production technology is simplified, solved and produced the problem that is subjected to the big restriction of batch, no matter the production batch size can be produced; (4) production equipment is simple, and small business also can produce, and has broken away from the historical situation of having only large-scale factories and miness to produce in the past; (5) its performance of the nose angle of casting is better than the nose angle of roll forming, and is more outstanding aspect high strength, abrasion resistance especially, the application life of having improved product significantly.
Description of drawings is as follows:
Fig. 1 is an elevation of the present invention;
Fig. 2 is a vertical view of the present invention.Wherein: the hole of (1)-nose angle main body, (2)-bent angle, (3)-broken line angle, (4)-be used to be connected and fixed
Embodiment:
Shape approximation quadrangle of the present invention, wherein there are two adjacent limits upwards to turn back and form bent angle (1), the angle that bent angle is relative is an acute angle, remain two jiaos and be the obtuse angle, broken line angle (3) is the right angle, be useful on 7 holes (4) that are connected and fixed at the middle part of nose angle main body (1), wherein a row is 4 holes, and a row is 3 holes, projection length of the present invention is 538 millimeters, projection is the wideest to be 300 millimeters, and the narrowest is 230 millimeters, long 220 millimeters an of broken line at broken line angle, another is long 230 millimeters, the center to center distance of two rounds is 80 millimeters, Yi Bian a row is that the shortest distance of pitch-row in 3 holes is 48 millimeters, it is 30 ° that bent angle is faced projected angle.Nose angle of the present invention is that its founding materials that uses is high manganese steel material with the ploughshare-like cast steel slash angle of cast shaping process method processing, and the thickness of its nose angle is that 40 millimeters nose angle thickness that form than section rolling are slightly high.
Claims (1)
1, a kind of nose angle of casting, its shape approximation quadrangle, two adjacent limits formation bent angle that upwards turns back is wherein arranged, the angle that bent angle is relative is an acute angle, and remaining two jiaos is the obtuse angle, and the broken line angle is the right angle, be useful on 7 holes that are connected and fixed at the middle part of nose angle, wherein a row is 4 holes, and a row is 3 holes, it is characterized in that:
(1) above-mentioned nose angle is the ploughshare-like cast steel slash angle with the processing of cast shaping process method;
(2) founding materials of above-mentioned nose angle is a high manganese steel material;
(3) thickness of above-mentioned nose angle is 40 millimeters.
