Abstract
The utility model relates to irregularly shaped seamless steel tubes, in particular to a seamless tube for a front axle of a tractor, which is characterized in that the section of a tube body (1) of the seamless tube for the front axle of the tractor is in a rectangular structure which is composed of a top edge (1.1), a bottom edge (1.2), a left edge (1.3) and a right edge (1.4), wherein the top edge (1.1) is punched outward to form an arc edge (2), the positions where the bottom edge (1.2) is connected with the left edge (1.3) and the right edge (1.4) are transited through arcs. The seamless tube for the front axle of the tractor enables the top edge to be punched outward to form the arc edge on the basis of a rectangle, thereby enabling the seamless tube for the front axle of the tractor to have light weight, high strength and strong stress resistance and torsional resistance. The positions where the bottom edge of the tube body is connected with the left edge of the tube body and the right edge of the tube body are transited through the arcs, thereby guaranteeing that the surface of the tube body is smooth.
Description
Technical field
The utility model relates to a kind of special-shaped seamless steel pipe, relates in particular to a kind of tractor front axle and uses weldless tube.
Background technique
At present, seamless steel pipe is widely used in manufacturing structure spare and mechanical parts, makes ring-shaped work pieces with seamless steel pipe, can improve stock utilization, simplifies manufacturing process, and economical with materials is also saved man-hour.The overwhelming majority is a pipe in seamless steel pipe in the past.
Yet pipe is because shape limits makes it can't be used for some particular surroundingss, because the moment of inertia of pipe and section modulus are less; Its bending resistance and anti-twisting property are relatively poor; Intensity is low, and the weight of pipe itself is bigger, and is bigger to the pressure of its supporting part; It is more to process the steel that pipe consumes, and makes that its cost is higher.Above a variety of causes has limited the Applicable scope of pipe, therefore under some particular surroundingss, does not adopt pipe to be used as structural member or machine part.
Need weldless tube weight to want light when for example the tractor front axle uses, and have higher intensity and certain bending resistance, anti-twisting property, pipe just can not reach requirement like this.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides that a kind of weight is light, intensity is higher, and bending resistance and the stronger tractor front axle of anti-twisting property are used weldless tube.
The purpose of the utility model is achieved in that
The utility model tractor front axle is with the rectangular structure in the cross section of the body of weldless tube, and this rectangular configuration is by top margin, base, the left side, and the right is formed, and wherein the outside punching press of top margin forms the circular arc limit, and arc transition is passed through in the said base and the left side, joint, the right.
Compared with prior art, the beneficial effect of the utility model is:
This tractor front axle forms circular arc limit with the outside punching press of top margin with weldless tube on the basis of rectangle; So not only make the tractor front axle lighter with the weight of weldless tube; Make that also its intensity is higher; Resistance to compression and anti-twisting property are stronger, and the base of body and the left side, joint, the right have guaranteed the surface smoothing of body through arc transition.
Description of drawings
Fig. 1 is the cross-sectional view of the utility model tractor front axle with weldless tube.
The schematic representation of the rectangular structure in cross section when Fig. 2 is 1 manufacturing of Fig. 1 middle tube body.
Wherein: body 1, top margin 1.1, base 1.2, the left side 1.3, the right 1.4, circular arc limit 2.
Embodiment
Referring to Fig. 1 and Fig. 2; The utility model relates to a kind of tractor front axle and uses weldless tube, and said tractor front axle is with the rectangular structure in cross section of the body 1 of weldless tube, and this rectangular configuration is by top margin 1.1, base 1.2, the left side 1.3; The right 1.4 is formed; Wherein top margin 1.1 outside punching presses form circular arc limit 2, and arc transition is passed through with the left side 1.3,1.4 joints, the right in said base 1.2, can guarantee the surface smoothing of body 1 like this.
Claims (1)
