Abstract
The utility model provides a pipe end flaring unit, which is composed of a handle, a joint plate, an elastic expansion sleeve, an expansion head rod, an elastic ring, and a double-acting cylinder exerting force. The elastic expansion sleeve is petaloid; the internal surface at the upper end of the elastic expansion sleeve is a circular conical surface, and the external surface at the upper end of the elastic expansion sleeve is a cylinder face, and a positioning step with the elastic ring enclosed in the middle is arranged on the external surface at the upper end of the elastic expansion sleeve; the lower end of the elastic expansion sleeve is connected with the double-acting cylinder; the upper part of the expansion head rod is a taper with small upper part and small lower part which is matched with the internal conical surface of the elastic expansion sleeve; and the lower end of the expansion head rod is fixed with the piston rod of the double-acting cylinder; the double-acting cylinder is fixed on the handle. The pipe end flaring unit has the advantages that a pipe end is flared simply; and the working efficiency is high. The pipe end flaring unit can be used for flaring a plurality of calibers, and is widely applicable.
Description
Technical field
The utility model relates to a kind of tube expander, particularly a kind of device of expanding pipe one end diameter.
Background technology
The pipe end mouth expander is a kind of equipment that the port diameter of pipe is expanded, and is used for the place that various pipe ports need hole enlargement.
Existing pipe end mouth expander is generally fairly simple, the one, make the mould of different-diameter and squeeze into by hand in the pipe end that needs enlarging, another kind of then be that mould with different-diameter is contained on the electric drill, above-mentioned these two kinds of mouth expanders are all undesirable, the one, with artificial or motor operation is inconvenient, efficient is low, and the 2nd, need the mould of multiple diameter, make when particularly needing the pipe end of multiple bore complicated, the cost height.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned defective of prior art and a kind of pipe end mouth expander is provided, and makes that its enlarging is more convenient, efficient is higher.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
The pipe end mouth expander, form by handle, connecting plate, elastic expansion sleeve, the two-way cylinder that dilates head rod, elastic ring and the application of force, described elastic expansion sleeve is petal-shaped, its upper end inner surface is a taper seat, outer surface is the face of cylinder, and establish one and locate step, the flexible circle of intermediate sleeve, the lower end is connected with two-way cylinder, dilating head rod top is and the supporting up big and down small circular cone of elastic expansion sleeve internal conical surface, the piston rod of lower end and two-way cylinder is fixed, and two-way cylinder and handle are fixed on the connecting plate.
Compared with prior art, advantage of the present utility model is:
Adopt handle and oil cylinder, can easily mouth expander be inserted pipe end, utilize oil cylinder work, the enlarging operation is fairly simple, high efficiency.
Can be used for the enlarging of multiple caliber, wide adaptability.

Fig. 2 is the structural representation after the enlarging of the utility model embodiment pipe end mouth expander pipe.
Fig. 3 is the structural representation of the utility model embodiment elastic expansion sleeve.
Fig. 4 is the vertical view of the utility model embodiment elastic expansion sleeve.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, the pipe end mouth expander is made up of handle 7, connecting plate 52, elastic expansion sleeve 2, the two-way cylinder 5 that dilates head rod 3, elastic ring 4 and the application of force.
Dilating head rod 3 tops is taper seat 31, matches with the elastic expansion sleeve internal conical surface, and lower end 32 is connected with oil cylinder piston bar 51 upper ends.
The oil-feed of two-way cylinder cavity of resorption dilates head rod and is in and unclamps the position, and under the elastic ring effect, the elastic expansion sleeve inner conical surface is embraced and dilated head rod 3 bottoms.
The switch of two-way cylinder 5 (not drawing among the figure) is preferably disposed on the handle 7, like this handled easily.
During the pipe end enlarging, operator grasps handle 7 will dilate head rod 3 and insert pipe end 1, and the positioning step 23 on elastic expansion sleeve 2 ends.Press the switch button that is contained on the operating grip, two-way cylinder 5 epicoele oil-feeds, it is descending to drive piston 5, drives by piston rod 51 that to dilate head rod 3 descending again, is up big and down small taper shape owing to dilate head rod 3, therefore dilate 3 pairs of elastic expansion sleeves of head rod 2 and produce the outer power of squeezing, under " splitting power " effect, elastic expansion sleeve 2 is tube wall 1 outer squeezing, and piston on earth, finish the enlarging action, see Fig. 1.
Unclamp button, it is up that the piston rod drive dilates head rod, " splitting power " elimination, and elastic ring shrinks the elastic expansion sleeve opening, throws off with tube wall.This moment, the operator took out the port mouth expander, carried out the enlarging operation of next pipe.
Also establish apparatus for adjusting position 6 in the above-mentioned oil cylinder 5, adjusting device shown in the embodiment is screw 61 and nut 62, screw 61 1 ends stretch in the chamber of two-way cylinder 5, the other end is connected with nut 62, by rotation nut 62, can change screw 61 and stretch into distance oil cylinder 5 chambeies in, thus the final position of adjustment piston 51, determine to dilate the Bottom Runby H of head rod thus, finally determine the size of pipe end enlarging.
