4. due to hollow central siphon and spindle nose machine-shaping respectively, so production facilities is simple, only need, according to traditional processing technology processing, reduce labor strength, cut down finished cost.
Accompanying drawing explanation
Fig. 1 is the solid farm trailer axletree of integral type of the prior art schematic diagram;
Fig. 2 is farm trailer tubular axle structural representation of the present invention;
Wherein, 1, hollow central siphon; 2, spindle nose; 3, spindle nose locating bush; 4, weld seam.
The specific embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the present invention is further elaborated.Should be appreciated that the specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As shown in Figure 2, the invention discloses the farm trailer of a kind of farm trailer tubular axle and job operation thereof and this axletree of employing, this farm trailer tubular axle, comprise hollow central siphon and be arranged at respectively two spindle noses at described hollow central siphon two ends, described spindle nose and described hollow central siphon are welded and fixed, inner side, described hollow central siphon two ends is welded with spindle nose locating bush, described spindle nose is near the middle part projection of one end of described hollow central siphon, described projection is inserted in the described spindle nose locating bush in described hollow central siphon, the described projection of described spindle nose and described spindle nose locating bush interference fit.
The load that the axletree of general farm trailer should be able to carry 8T-10T, in order to guarantee under the load-carrying capacity of axletree, the productive costs and the use cost that reduce axletree, make axletree lightweight, and employing sectional dimension is 80mm*80mm, 90mm*90mm, the novel hollow square tube of three kinds of specifications of 100mm*100mm is processed hollow central siphon, and material adopts 20Mn2 low-alloy steel, adds and man-hour it is carried out to modifier treatment, strengthen central siphon intensity, and take spindle nose welding manner.
Because traditional spindle nose welding manner exists welding position, therefore load-carrying capacity is low, the present invention adopts spindle nose locating bush and spindle nose interference fit, and uses CO2 protection weldering, solves this technical barrier.Effectively solve the problem because of the short low bearing capacity of weld seam, greatly improved axletree service life.
Trailer tubular axle work flow of the present invention is as follows:
The processing of spindle nose: sawing sheet---> prtreatment---> fine limit work;
---------> is modified, and---> processes diplopore to > welding spindle nose locating bush to the flat overall length of > in > alignment---> digs groove---in the processing of hollow central siphon: sawing sheet;
The processing of axis body assembly: last item head (the spindle nose locating bush interference fit in spindle nose and hollow central siphon)---> welds spindle nose---> alignment.
Owing to requiring load-carrying capacity higher, the cross section of central siphon requires little, therefore although feasible with traditional solid square steel, solid square steel cost costliness and Heavy Weight.In the present invention, at 80mm*80mm, 90mm*90mm, is used novel hollow square tube material 20Mn2 under three kinds of specifications of 100mm*100mm, and processes hollow central siphon through heat treatment quenching and tempering.Hollow central siphon is selected novel hollow square tube, no matter aspect load-carrying capacity or cost control, can reach ideal effect (the solid square steel of hollow square tube weight ratio tradition alleviates more than 40%).
20Mn2 low-alloy steel, during deformability cold, plasticity is high, and low-temperature properties is good, and can greatly increase by heat treatment the mechanical property of hollow central siphon.Comparing the solid square steel that tradition is used, just adopt common Q 345 low-alloy steels, is that tensile strength, yield strength, material hardness etc. are all less than 20Mn2 low-alloy steel.
Bi-material is compared as follows table:
| Material | 20Mn2 | Q345 |
| Tensile strength | 785MPa | 630MPa |
| Yield strength | 590MPa | 275MPa |
| Absorbed-in-fracture energy | 47Aku/J | 34Akv/J |
| Hardness | 230-260HB | 160-200HB |
| Heat treatment mode | Cold drawn, modifier treatment | Heat prick, without modifier treatment |
Because hollow central siphon of the present invention is what to separate with spindle nose.With the independent fine limit work spindle nose of conventional digital controlled lathe, just can guarantee the working accuracy of spindle nose bearing position.The processing of hollow central siphon is also to machine under conventional equipment.To after two spindle noses and hollow central siphon interference fit force together, weld.
When hollow shaft tube section is larger, weld seam is longer, and weld seam load-carrying capacity still can.But very short for the hollow central siphon weld seam of small bore, load-carrying capacity is limited.In order to eliminate the inadequate natural endowment of weld seam; by spindle nose locating bush and spindle nose interference fit; and be pressed on together, then, with the welding manner machine-shaping of CO2 protection weldering, make the Welding Problems of hollow central siphon and spindle nose effectively solve and improve the integrated carrying ability of tubular axle.Greatly improve the service life of tubular axle, by fatigue test, tubular axle of the present invention can reach 800,000 times, has guaranteed the load-carrying capacity of axletree.
Use novel hollow square tube and the moulding of spindle nose separate machined.Production facilities is simple, only need, according to traditional processing technology processing, reduce labor strength, cuts down finished cost, and is compared as follows table with the shaft technique of prior art:
By adopting technique scheme disclosed by the invention, obtained following useful effect:
1. farm trailer tubular axle of the present invention is used novel hollow square tube, can effectively control purchase cost and use cost.Farm trailer tubular axle of the present invention is hollow central siphon due to what adopt, and the solid central siphon that weight ratio is traditional is reduced more than 40%.With 90mm*90mm, the common shaft that wheelspan is 2000mm is example, and axis body weight reaches 127KG.And the farm trailer tubular axle of same specification disclosed by the invention, axis body weight only has 75KG, by 5000 axletrees of production in 1 year, 6 yuan of calculating of per kilogram, adds the traffic cost of saving, can save more than 1,600,000 for axletree manufacturing enterprise every year.Because tubular axle overall weight of the present invention alleviates, make to adopt the in use oil consumption of farm trailer of tubular axle of the present invention to save, the wearing and tearing of each parts also can reduce, corresponding lengthening in service life.
2. the hollow square tube that is 20Mn2 low-alloy steel due to the hollow central siphon employing material of farm trailer tubular axle of the present invention is made, thereby making it compare the traditional solid axle that uses solid square steel (Q345 low-alloy steel) to make, is that tensile strength, yield strength, hardness etc. are all significantly increased.
3. owing to adopting spindle nose locating bush and spindle nose interference fit; and the processing mode that uses CO2 protection to weld; effectively solved the problem because of the short low bearing capacity of weld seam; greatly improved the service life of tubular axle of the present invention; the tubular axle of making by job operation of the present invention; by fatigue test, can reach 800,000 times, fully guaranteed the load-carrying capacity of tubular axle.
4. due to hollow central siphon and spindle nose machine-shaping respectively, so production facilities is simple, only need, according to traditional processing technology processing, reduce labor strength, cut down finished cost.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be looked protection scope of the present invention.
