Abstract
The utility model discloses a simple pipe expander, which solves the problems of complicated structure, easiness in damage, high cost and the like of existing pipe expanding equipment. The simple pipe expander comprises a bolt, a pipe expanding block, a positioning block and a first nut, wherein the pipe expanding block and the positioning block are sequentially sleeved on the bolt, the first nut is fixedly screwed on the bolt outside the positioning block, the pipe expanding block is a conical block and is sleeved on the bolt with a large-diameter surface facing a nut end, and the first nut is connected with a hanging ring. Different pipe expanding blocks can be selected for replacement to expand metal pipes according to different requirements of pipe expansion, and the simple pipe expander is extremely practical and convenient. In addition, the simple pipe expander further has the advantages of simple structure, easiness in operation, durability in use, low cost and the like, and is worthy of popularization and use.
Description
Technical field
The utility model belongs to a kind of metal tube processing unit (plant), is specially a kind of simple and easy tube expander.
Background technology
In the use of metal tube; Little and the situation about can't use of metal tube bore can appear; At this moment just need small-bore metal tube be swollen through tube expander; Meeting instructions for use, and existing pipe expanding equipment mostly damages when complex structure, improper use easily, and price is also more expensive relatively.
Summary of the invention
The purpose of the utility model is to overcome above-mentioned shortcoming of the prior art, and a kind of simple in structure, processing ease, durable in use is provided, and cheap simple and easy tube expander.
The utility model is realized through following technical scheme:
A kind of simple and easy tube expander; Comprise bolt, expand tube piece, locating piece and first nut; Wherein expand tube piece and locating piece are sleeved on the bolt successively, twist intrinsic first nut on the outer bolt of locating piece then, and described expand tube piece is circular cone and is set on the bolt towards the nut end with big diametral plane; Be connected with suspension ring on described first nut.
The method for using of the utility model is following:
At first; Expand tube piece and locating piece that the size Selection that dilates according to the metal tube needs is suitable; The expand tube piece that chooses, locating piece are sleeved on the bolt successively, and first nut that will have suspension ring is again twisted solid on bolt, and with expand tube piece and locating piece fixing and locking on bolt; Then,, simple and easy tube expander is put in the metal mouth of pipe that need dilate with first nut that has suspension ring inwardly, at this moment, locating piece has overlapped and has inserted in the mouth of pipe, and the expand tube piece is owing to pyramidal structure is connected to the mouth of pipe; At last,, the expand tube piece is slowly drawn in the metal tube, and under the effect of pulling force, made simple and easy tube expander slowly through metal tube, to reach the purpose of enlarged metal pipe caliber through the suspension ring on first nut are applied pulling force.Wherein, locating piece is in order to locating the mobile guide of simple and easy tube expander in metal tube, and the direction of pull that acts on the tube expander is in by the axis direction in expander road all the time; The expand tube piece of taper has then been realized the (see figure 2) that dilates to the metal tube caliber.
Further, be mutual between described locating piece and the expand tube piece through corresponding boss and groove on it
Be connected.Being connected of projection and groove can make and connect more fasteningly between locating piece and the expand tube piece, helps carrying out smoothly of expand tube operation.
On the bolt between the locating piece and first nut, also twist intrinsic second nut.The effect of second nut is that expand tube piece, locating piece are locked through bolt, makes first nut of band suspension ring only bear the pull effect, is of value to the carrying out of expand tube operation.
Between the locating piece and second nut, also be provided with packing ring.Packing ring can push against locating piece and expand tube piece, and can prevent the loosening of second nut, makes between expand tube piece, locating piece and second nut more fastening.
The utility model can dilate requirement according to different pipelines, selects and the expand tube piece of changing different size dilates metal tube very practical and convenient.In addition, that the utility model also has is simple in structure, processing ease, advantage such as durable in use, cheap, is worth of widely use.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the use sketch map of the utility model.
Among the figure: 1-bolt, 2-expand tube piece, 3-locating piece, 4-packing ring, 5-second nut, 6-first nut, 7-suspension ring, 8-metal tube.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to describe:
Like Fig. 1, shown in 2; A kind of simple and easy tube expander; Comprise bolt 1, expand tube piece 2, locating piece 3 and first nut 6; Wherein expand tube piece 2 is sleeved on the bolt 1 with locating piece 3 successively, twists intrinsic first nut 6 on the bolt 1 outside the locating piece 3 then, and described expand tube piece 2 is set on the bolt 1 towards the nut end for circular cone and with big diametral plane; Be connected with suspension ring 7 on described first nut 6.
Further, be through corresponding boss and groove on it between described locating piece 3 and the expand tube piece 2
Cooperatively interacting connects, so that the connection between it is more fastening.
On the bolt 1 between the locating piece 3 and first nut 6, also twist intrinsic second nut 5.The effect of second nut 5 is that expand tube piece 2, locating piece 3 are locked through bolt 1, makes 6 on first nut of band suspension ring 7 bear the pull effect, is of value to the carrying out of expand tube operation.
Between the locating piece 3 and second nut 5, also be provided with packing ring 4, packing ring 4 can push against locating piece 3 and expand tube piece 2, and can prevent the loosening of second nut 5, makes between expand tube piece 2, locating piece 3 and second nut 5 more fastening.
