Abstract
The utility model discloses a heat exchange tube cutting tool. The heat exchange tube cutting tool comprises a tool bar and a tool bit, wherein a through hole is formed in the top of the tool bar, a hinge pin is inserted into the through hole, the tool bit is mounted on the hinge pin, the outside of the hinge pin is fastened through a fastener, a check ring is mounted on the lower portion of the tool bar, a pin hole is formed in one side of the check ring, and a tacking piece is mounted inside the pin hole. The heat exchange tube cutting tool has the advantages that the tool bit can be used for cutting in a counterclockwise mode and retracting in a clockwise mode, the structure is simple, and using is fast and convenient.
Description
Technical field
The utility model relates to a kind of heat exchanger tube tube cutting tool.
Background technology
For fixed tube-sheet exchanger, because of the limitation of structure, while after the minority pipe is due to the many reasons corrosion and damage, needing to change, at first utilize the tube drawing specific purpose tool that the pipe of damage is extracted, the instrument of tube drawing and replace tubes has a variety of at present.If large-area replace tubes can fall the weld metal of heat exchanger by bit drills on drilling machine, heat exchanger tube can be relatively easy to extract out like this.For fixed heat exchanger at the scene, can only remove weld metal with specific purpose tool, then with hydraulic push-type or screw thread tensile force type tube drawing specific purpose tool, pipe be pulled out.Therefore, need to provide a kind of new technical scheme to solve the problems referred to above.
The utility model content
The purpose of this utility model is to provide a kind of tube cutting tool of heat exchanger tube quickly and easily.
The technical solution adopted in the utility model is:
The heat exchanger tube tube cutting tool, this tube cutting tool comprises knife bar and cutter head, described knife bar top has a through hole, in described through hole, be inserted with bearing pin, described cutter head is installed on bearing pin, and described bearing pin is fastening by securing member outward, and described knife bar bottom is equipped with back-up ring, described back-up ring one side has pin-and-hole, is equipped with and marks closely part in described pin-and-hole.
Described securing member is nut.
The described part of marking closely is that interior hexagonal flush end is marked closely screw.
The beneficial effects of the utility model: cutter head cuts counterclockwise, clockwise withdrawing, simple in structure, uses quick and convenient.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 be in Fig. 1 A-A to structural representation.
Wherein: 1, knife bar, 2, back-up ring, 3, nut, 4, cutter head, 5, interior hexagonal flush end marks closely screw, 6, through hole, 7, bearing pin, 8, pin-and-hole.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
As illustrated in fig. 1 and 2, heat exchanger tube tube cutting tool of the present utility model, this tube cutting tool comprises knife bar 1 and cutter head 4, knife bar 1 top has a through hole 6, in through hole 6, is inserted with bearing pin 7, and cutter head 4 is installed on bearing pin 7, bearing pin 7 is outer fastening by nut 3, knife bar 1 bottom is equipped with back-up ring 2, and back-up ring 2 one sides have pin-and-hole 8, interior hexagonal flush end is installed in pin-and-hole 8 and marks closely screw 5.
For fixed tube-sheet exchanger, owing to after the many reasons corrosion and damage, needing to change, can adopt tube cutting tool of the present utility model to carry out replace tubes, according to tube plate thickness and switch heat pipe internal diameter, wall thickness, determine the eccentric location dimension of length, external diameter and the cutter head 4 of frock knife bar 1, according to the heat exchange tube material mechanical performance, determine the overall dimensions of cutter head 4 and the material of cutter head 4, cutter head 4 can be selected high, the anti abrasive carbide alloy of hardness.
