Abstract
The utility model relates to a fan-shaped corner-unfilled tube for excavators. A tube body (1) of the fan-shaped corner-unfilled tube has a section with an irregularly-shaped structure; the irregularly-shaped structure comprises a horizontal straight section (1-1), a vertical straight section (1-2) and an arc section (1-3); all the sections of the tube body (1) are connected through arc transition; a zinc coating (2) is applied on the surface of the tube body (1); and the fan-shaped corner-unfilled tube is made of 20Mn2. The fan-shaped corner-unfilled tube for excavators has high strength and better shock-proof and anticorrosion effects.
Description
(1) technical field
The utility model relates to a kind of special-shaped seamless steel pipe, especially relates to a kind of excavator with fan-shaped unfilled corner pipe, belongs to the metal material technical field.
(2) background technology
At present, seamless steel pipe is widely used in manufacturing structure spare and machine components, as steel scaffold of using in oil drill rocker, truck drive shaft, bicycle rack and the building operations etc.Make ring-shaped work pieces with seamless steel pipe, can improve stock utilization, simplify manufacturing process, economical with materials and machining period as rolling bearing lasso, jack cover etc., are extensively made with seamless steel pipe at present.Seamless steel pipe still is various conventional weapon indispensable material, and gun barrel, gun barrel etc. is all wanted steel pipe manufacturing.In these seamless steel pipes, round tube can be carried more fluid.In addition, ring cross-section is when bearing inside or outer radial pressure, and is stressed more even, and therefore most seamless steel pipes are pipes.
Yet pipe also has certain limitation:
The shape restriction of pipe makes it can't be used for some particular surroundings;
Because the moment of inertia of pipe and modulus of section are less, its bending resistance and anti-twisting property are relatively poor;
The weight of pipe itself is bigger, and is bigger to the pressure of its support component.
Above a variety of causes has limited the scope of application of pipe, does not therefore adopt pipe to be used as structural member or machine part under some particular surroundings.For example excavator need consider that its intensity wants high and want certain shockproof and anti-corrosion capability, so just can not use pipe to make.
(3) summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of excavator with fan-shaped unfilled corner pipe, and this excavator is with the intensity height of fan-shaped unfilled corner pipe, and shockproof and anticorrosion ability is better.
The purpose of this utility model is achieved in that
A kind of excavator is with fan-shaped unfilled corner pipe, the section of the body of this fan-shaped unfilled corner pipe is abnormally-structured, this is abnormally-structured to include horizontal straight section, the vertical edge section, arc section, the bottom of described body is horizontal straight section, the left end of described horizontal straight section links to each other with the vertical edge section, the upper end of described vertical edge section links to each other with horizontal straight section, the right-hand member of described horizontal straight section links to each other with arc section, the lower end of described arc section links to each other with the right-hand member of horizontal straight section, the left end of described horizontal straight section links to each other with the upper end of vertical edge section, the lower end of described vertical edge section links to each other with the right-hand member of the horizontal straight section of body bottom, be connected to arc transition between each limit section of described body, the surface of described body is covered with zinc coat, and the material of described fan-shaped unfilled corner pipe is 20Mn2.
The beneficial effect that the utlity model has is:
This excavator is with the intensity height of fan-shaped unfilled corner pipe, and shockproof and anticorrosion ability is better.
(4) description of drawings
Fig. 1 is the section structure schematic diagram of the utility model excavator with fan-shaped unfilled corner pipe.
Wherein: body 1, horizontal straight section 1-1, vertical edge section 1-2, arc section 1-3, zinc coat 2.
(5) specific embodiment
As Fig. 1, the utility model relates to a kind of excavator with fan-shaped unfilled corner pipe, the section of the body 1 of this fan-shaped unfilled corner pipe is abnormally-structured, this is abnormally-structured to include horizontal straight section 1-1, vertical edge section 1-2, arc section 1-3, the bottom of described body 1 is horizontal straight section 1-1, the left end of described horizontal straight section 1-1 links to each other with vertical edge section 1-2, the upper end of described vertical edge section 1-2 links to each other with horizontal straight section 1-1, the right-hand member of described horizontal straight section 1-1 links to each other with arc section 1-3, the lower end of described arc section 1-3 links to each other with the right-hand member of horizontal straight section 1-1, the left end of described horizontal straight section 1-1 links to each other with the upper end of vertical edge section 1-2, the lower end of described vertical edge section 1-2 links to each other with the right-hand member of the horizontal straight section 1-1 of body 1 bottom, be connected to arc transition between each limit section of described body 1, the surface of described body 1 is covered with zinc coat 2, and the material of described fan-shaped unfilled corner pipe is 20Mn2.
