Expander with positioning structure

The present invention relates to a pipe expander, and more particularly to a pipe expander having a positioning structure.

According to the general pipe fittings, if the distance is long or there is a transfer road section, it is often necessary to carry out the operation of expanding the pipe joint. For example, Taiwan’s new patent No. M453545 discloses a structure of the pipe expander, which uses the pipe clamp 5 The block 6 is clamped, and the clamping block 6 is placed in the guiding groove 13 of the body portion 11, so that the tapered head 43 is aligned with the tubular member 5, and the handle 42 can be pulled to expand the end of the tubular member 5. The tube expands the nozzle of the tube 5 into a tapered shape to facilitate the jointing operation of the tube.

However, the conventional expander does not have any positioning structure for positioning the clamp block 6. Although the adjusting screw can fix the clamp block 6 in the guide groove 13, the tapered head 43 is aligned with the nozzle of the tubular member 5. In the case where the eccentricity or the misalignment position is often incorrect, if the user expands the tube 5 by the conical head 43 at this time, the tube 5 is easily damaged. Therefore, the conventional expander must be extra. It takes a lot of time and manpower to align the opening of the tube 5 below the conical head 43 to avoid damage to the tube 5, which is very inconvenient.

In view of this, how to develop a pipe expander having a positioning structure, and positioning and fixing the clip 6 in the guide groove 13 is a problem that the relevant industry must solve.

In order to solve the above problems, the present invention provides a pipe expander having a positioning structure, which has a positioning device for positioning a pinch tube seat in a guide groove of the seat body, so that each pipe expansion hole can be segmentally positioned in the pipe expansion. Below the cone.

In order to achieve the above object, the present invention provides a pipe expander having a positioning structure, comprising: a body having a body and a neck connected to the top of the body, wherein the body has a guiding groove and a neck The rotating screw is provided with a rotating screw capable of up-and-down displacement, and one end of the rotating screw has a expanding pipe cone and is oriented toward the guiding groove; a clamping pipe seat is slidably disposed in the guiding groove, wherein the clamping pipe seat is provided with plural a plurality of positioning holes are formed on one side of the pin holder, and each of the positioning grooves corresponds to each of the expansion holes; a positioning device is disposed on the side wall of the body and located in the guiding groove One side, wherein the positioning device can respectively abut the positioning grooves, so that the positioning device can position the pinch tube segment according to the position of each of the expansion holes, thereby making the expansion holes segmentable Located below the expansion cone; and an adjustment screw pivoted to the body and located on the other side of the clamp seat for locking the clamp base.

By the above, the achievable effect of the present invention is that the creation has a positioning device, which can position the pinch holder according to the position of each expansion hole and the segmentation card in the guide groove, so that the expansion holes can be divided. The segment is positioned below the expansion cone. Therefore, when a pipe member is clamped to one of the pipe expansion holes, the manpower and time cost can be saved by the creation, and the pipe expansion hole can be quickly formed. And accurately positioned under the expansion cone, so that the expansion cone can be accurately aligned with the nozzle of the pipe to avoid damage to the pipe.

The positioning device 30 can position the pinch holder 20 in a stepwise manner according to the position of each of the expansion holes 23, so that the expansion holes 23 can be segmentally positioned below the expansion tube cone 18.

An adjusting screw 40 is pivotally disposed on the body 11 of the base 10 and located on the other side of the pin holder 20, wherein one end of the adjusting screw 40 can be segmented against the locking recesses of the pin holder 20 The groove 25 is used to lock the pinch base 20, and an adjusting kit 41 is provided between the adjusting screw 40 and the body portion 11 to prevent the body 11 from being worn, as shown in FIGS. 4 and 5.

The above is an overview of the structure and shape of the creation, and the principles and methods of use that can be achieved by this creation are as follows:

When a pipe fitting 50 needs to be expanded, the pinch holder 20 of the present invention is detached from the guide groove 13, and the pipe member 50 is clamped to one of the pipe sockets 20 according to the diameter of the pipe mouth. 23, the pinch holder 20 sandwiching the tube member 50 is placed in the guide groove 13 of the seat body 10. At this time, the pinch holder 20 is slid in the guide groove 13 to adjust the pinch holder 20 in the guide groove 13. When the pin holder 20 slides in the guide groove 13, it abuts against the positioning rod 32 of the positioning member 26 of one of the positioning grooves 24 of the pin holder 20, which can press the positioning spring 31 to enter the positioning hole 14 When the pin holder 20 slides to the positioning hole 26 of the other positioning groove 24 and the positioning hole 14 is aligned, the elastic force of the positioning spring 31 can push back the positioning rod 32, so that the positioning rod 32 can be pressed against the other. The positioning member 26 of the positioning groove 24 is used for the positioning of the segment. Therefore, the positioning device 30 of the present invention can position the pinch holder 20 by the position of each of the expansion holes 23, so that the expansion tube is expanded. The holes 23 can be positioned under the expansion cone 18 in sections, and the positioning members 26 of the positioning grooves 24 can be used to prevent damage of the positioning grooves 24.

Therefore, after the expansion pipe hole 23 with the pipe member 50 is adjusted and positioned under the expansion pipe cone 18, as shown in FIG. 5, the pipe socket 20 is then locked by the adjusting screw 40, so that the pipe expansion cone 18 is accurately aligned. The nozzle of the pipe member 50 is as shown in FIG. 6. At this time, the rotary handle 19 can be rotated to move the expansion pipe cone 18 in the direction of the pipe member 50, and the pipe expanding operation is performed, so that the pipe mouth of the pipe member 50 is expanded into a tapered shape. In order to facilitate the joint work of the pipe 50.

In summary, according to the pipe expander 100 having the positioning structure of the present invention, when a pipe member 50 needs to be expanded, the pipe member 50 is clamped to one of the pipe expansion holes 23 of the pinch base 20, and the pipe is clamped. The seat 20 slides in the guide groove 13, so that the expansion hole 23 sandwiching the pipe member 50 can be quickly and accurately positioned below the expansion pipe cone 18. Therefore, the positioning device 30 of the present invention can save a lot of manpower and time cost. The user can easily and accurately align the expansion tube cone 18 with the nozzle of the tube member 50, so as to facilitate the rapid progress of the tube expansion processing, which is very convenient, and can avoid the occurrence of damage of the tube member 50.
