Fig. 1 is the structural representation of a kind of machinery expanding device for steel pipe that the utility model proposes.
Numeral and the corresponding component title represented by letter in figure:
1, steel pipe 2, expanding taper head 3, expander die 4, skewback 5, fixed dam 6, draw bail 7, oil cylinder
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with diagram and specific embodiment, setting forth the utility model further.
As shown in Figure 1, a kind of machinery expanding device for steel pipe that the utility model proposes, comprise steel pipe 1, expanding taper head 2, skewback 4, expander die 3, baffle plate 5, draw bail 6 and oil cylinder 7, it is described steel pipe 1 on the left of the machinery expanding device of described steel pipe, described steel pipe 1 mid portion is described expanding taper head 2, described expanding taper head 2 middle part is trapezium structure, connecting on the right side of trapezium structure is rectangle structure body, connecting on the left of trapezium structure is rectangular structure body, a rectangular recess is provided with on the left of described expanding taper head, the described upper and lower both sides of expanding taper head are equipped with while be the trapezium structure skewback 4 at right angle, described skewback about 4 both sides are equipped with cuboid expander die 3, on the right side of described expanding taper head 2, the upper and lower both sides of rectangular structure are equipped with fixed dam 5, it is described oil cylinder 7 on the right side of described machinery expanding device, what connect described expanding taper head 2 and described oil cylinder 7 is described draw bail 6.
Further, described fixed dam 5 is made up of some fixing back-up rings.
Further, be circular cylinder structure on the left of described draw bail 6, position, intermediate portion is provided with moving piston, and its right part is hollow pipe.
Described oil cylinder pulls described expanding taper head to the right, described expanding taper head promotes described skewback and described mould is expanded, reach setting size time described expanding taper head to left movement, described skewback and described mould reduce, and complete the expanding of a step pitch, after described steel pipe movement step pitch, repeat above-mentioned action, until steel pipe completes expanding, a kind of like this operating process can solve the problem on deformation of steel pipe well, make steel pipe more firm, improve the overall mechanical property of steel pipe.
More than show and describe general principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
