Abstract
A seamless steel tube top bending clamp head comprises a middle shaft, rotating shafts, pressing nuts and outer roller sleeves, wherein outer threaded shafts are arranged on two sides of the middle shaft, the rotating shafts are arranged on the outer sides of the outer threaded shafts, the pressing nuts are screwed on the outer threaded shafts, and each outer roller sleeve is arranged on one side of the middle shaft and is pressed by the pressing nut. A middle roller is arranged in an outer roller and is also sleeved on one side of the middle shaft, and the diameter of the middle roller is smaller than that of the outer roller. The seamless steel tube top bending clamp head enables rolling wheels to be decomposed and assembled by utilizing gradually decreased roller plates, and the roller plates are thick enough and have enough mechanical strength. The seamless steel tube top bending clamp head is of a combination type, rolling wheels with different arc faces are combined, and therefore, waste is reduced.
Description
Technical field
The utility model relates to a kind of seamless steel pipe bending dop, relates in particular to a kind of seamless steel pipe bending dop that can assembling combination.
Background technology
In Steel Structural Design manufacturing processing, need a large amount of steel pipes is carried out bending, this just needs a large amount of bending running rollers.
And the diameter of at every turn wanting the steel pipe of bending is not certain, cooperates the steel pipe of each diameter, just needs special running roller.
Especially for large diameter steel pipe, or the steel pipe of major-diameter thick-wall, change when a lot of at diameter of steel tube, the quantity of the running roller that is equipped with is just very considerable.
Some running roller access times are arranged seldom, so just cause waste.
The utility model content
In order to solve the problems referred to above that exist in the prior art; The utility model provides a kind of seamless steel pipe bending dop, and the seamless steel pipe bending dop of the utility model is knockdown, through selecting different roller plates; The running roller of forming different cambered surfaces has so just reduced waste.
The utility model is through adopting following technical scheme to realize:
Manufacture and design a kind of seamless steel pipe bending dop, comprising:
One axis, there is the external screw thread axle on said axis both sides;
The outside of said external screw thread axle is a turning cylinder;
One clamp nut is spun on the external screw thread axle;
One outer roller is enclosed within the one side and the compressing of compacted nut of axis.
Have central roll also to be enclosed within one side of axis in the said outer roller, and diameter is less than outer roller.
Have interior roller also to be enclosed within one side of axis in the said central roll, and diameter is less than central roll.
Compared with prior art, the utility model decomposes running roller, comes assembly unit with the roller plate that successively decreases step by step, and said roller plate is enough thick, and enough mechanical strengths are arranged; So the seamless steel pipe bending dop of the utility model is knockdown, through selecting different roller plates, form the running roller of different cambered surfaces, so just reduced waste.
Description of drawings
Fig. 1 is the sketch map of a kind of seamless steel pipe bending of the utility model dop front view;
Fig. 2 is the sketch map of a kind of seamless steel pipe bending of the utility model dop vertical view;
Fig. 3 is the sketch map of a kind of seamless steel pipe bending of the utility model dop stereogram.
Label among the figure:
1 axis, 2 outer rollers
6 external screw thread axles, 7 turning cylinders
100 steel pipes to be curved.
The specific embodiment
For principle and the structure that further specifies the utility model, combine accompanying drawing that the preferred embodiment of the utility model is elaborated, yet said embodiment is merely the usefulness that furnishes an explanation and explain at present, can not be used for limiting the scope of patent protection of the utility model.
Like Fig. 1～shown in Figure 3, manufacture and design a kind of seamless steel pipe bending dop, comprising:
One axis 1, there is external screw thread axle 6 on said axis 1 both sides;
The outside of said external screw thread axle 6 is a turning cylinder 7;
One clamp nut 5 is spun on the external screw thread axle 6;
One outer roller 2 is enclosed within the one side and 5 compressings of compacted nut of axis 1.
Have central roll 3 also to be enclosed within one side of axis 1 in the said outer roller 2, and diameter is less than outer roller 2.
Have interior roller 4 also to be enclosed within one side of axis 1 in the said central roll 3, and diameter is less than central roll 3.
The beneficial effect of the utility model is: running roller is decomposed, come assembly unit with the roller plate that successively decreases step by step, said roller plate is enough thick, and enough mechanical strengths are arranged; So the seamless steel pipe bending dop of the utility model is knockdown, through selecting different roller plates, form the running roller of different cambered surfaces, so just reduced waste.
During construction,, just can carry out the bend pipe operation that next step bends steel pipe 100 to be curved as long as the equipment axle sleeve is stuck on the turning cylinder 7.
Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection domain of the utility model.
