Abstract
The utility model relates to a pear-shaped casing roller which comprises a main body and a working head, wherein the main body is columnar, the working head is in cone shape, and the main body and the working head adopt integral structure design. The pear-shaped casing roller has the advantages of being simple in structure, high in working efficiency, and convenient to operate and being widely used for reshaping the tubular metal device.
Description
Technical field
The utility model relates to a kind of shaping tool, particularly relates to a kind of pyriform tube expander.
Background technology
Tube expander is the shaping tool that is used to repair down-hole casing, and present tube expander generally adopts the roller reshaper, and structure is complicated, inconvenient operation, thus influenced work quality and operating efficiency.
Summary of the invention
The utility model has overcome deficiency of the prior art, and pyriform tube expander a kind of simple in structure, easy to operate is provided.
In order to address the above problem, the utility model adopts following technical scheme:
The pyriform tube expander comprises main body and working head, and main body is column, and working head is the centrum shape, and main body and working head adopt the integral structure design.
Described body surfaces is provided with helicla flute.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is simple in structure, and is easy to operate, effectively reduced operation easier, improved operating efficiency.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model head force diagram.
The specific embodiment
The pyriform tube expander, as shown in Figure 1, comprise main body 1 and working head 2, main body 1 is column, and working head 2 is the centrum shape, and main body 1 adopts the integral structure design with working head 2.Main body 1 surface is provided with helicla flute 3.As shown in Figure 2, when drilling tool imposed on the utility model tube expander active force P, cross component force F that moment produced that working head 2 contacts with the casing deformation position and working head 2 partical gravity N directly squeezed expansion set pipe deformation place, thereby reached the purpose of shaping.
Claims (2)
