Abstract
A quick tube drawing device features that its tube drawing head is a conic screw rod with oblique teeth and is screwed in the tube to be drawn out by a certain depth, and the oblique teeth on the surface of tube drawing head can pull the tube easily.
Description
Technical field
The utility model relates to a kind of hardware ﹠ tools, especially the quick pipe extractor of more salvaged pipes being pulled out during the pipe in the exchange device at condenser, evaporimeter, boiler etc.
Background technology
It is very short as first that existing pipe extractor is located at the tube drawing of main mandrel front end, can only be used for the short salvaged pipes of the equipment of extracting, and just is difficult to extract for the long old pipe in some equipment.
Summary of the invention
In order to overcome the deficiency of existing pipe extractor, the utility model provides a kind of new pipe extractor, can quickly and easily long old pipe in some equipment be pulled out.
The quick pipe extractor that the utility model provides comprises main mandrel and is located at the tube drawing head of main mandrel front portion that the tube drawing head is the conical helical teeth threaded rod that fuses with main mandrel.
The beneficial effects of the utility model are, owing to adopt conical helical teeth threaded rod as the tube drawing head, and fuse with main mandrel, can be during use according to the salvaged pipes of different length, select the tube drawing head of respective length, rotate main mandrel, the tube drawing head is screwed in the salvaged pipes, the helical teeth screw thread of tube drawing head surface is easy to pipe is held, and just can fast salvaged pipes be extracted.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model
In Fig. 1,1. tube drawing head, 2. pipe box, 3. shell, 4. thrust bearing, 5. nut, 6. main mandrel.
The specific embodiment
In Fig. 1, the front portion of main mandrel (6) is made the conical helical teeth threaded rod of different size length as required and is made the utility model with pipe box (2), shell (3), thrust bearing (4), nut (5) assembling.When using the utility model tube drawing, as long as tube drawing head (1) is proceeded to the required degree of depth toward the pipe inward turning, the helical teeth screw thread on tube drawing head (1) surface is easy to hold tube wall, the front end of pipe box (2) is propped up the tube sheet of original fixing tube again, and rotation nut (5) just can be pulled out pipe rapidly.
