The pipe end facing machine has the advantages that a machining mode on the basis of the inner walls of the thermally-expanded steel pipes is adopted, so that the steel pipe machining precision can be guaranteed, and the steel pipe machining qualified rate can be increased.
Description
Technical field
The present invention relates to the steel pipe manufacture field, relate in particular to a kind of pipe end facing machine that the hot-expanding steel tube end face groove is processed that is used for.
Background technology
Seamless steel pipe expands and to add man-hour carrying out heat, usually needs the hot-expanding steel tube pipe end is carried out to the groove processing.But due to wall unevenness, even or bore presents and loses circle phenomenons such as (in the roundness tolerance scopes) hot-expanding steel tube, causes the mouth of pipe in groove processing very easily to occur that the cutting of local location large tracts of land or cutting, less than phenomenon, have a strong impact on the groove quality of pipe fitting.And the pipe fitting welding process be take pipe fitting inner wall as benchmark, and the processing of pipe fitting end face groove is to take the pipe fitting axle center as benchmark, so adopt the stationary knife processing method that the centre of gyration is machining benchmark unreasonable.
Summary of the invention
The problem existed in order to overcome prior art, the problem to be solved in the present invention be to provide a kind of simple in structure, for the hot-expanding steel tube end face being carried out to the pipe end facing machine of groove processing, this pipe end facing machine is to take the processing mode that the hot-expanding steel tube inwall is benchmark, can meet the pipe bevel dimensional requirement after processing.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of hot-expanding steel tube pipe end facing machine is provided, slidably connect collar bush on frame, described collar bush is driven by feed mechanism, be rotatably connected to main shaft in described collar bush, one end of described main shaft is connected with drive motors, the other end leans out described collar bush and is connected with a cutterhead, described cutterhead is provided with chute near the end face of described frame, the periphery of described cutterhead is provided with groove, and described groove radially communicates with described chute, the knife rest that can move in chute is installed in described chute, the bottom of described knife rest is fixed with spring and removable pin, described spring is fixed in described chute, the other end of described removable pin is slidably mounted in described groove, the groove cutter is installed on described knife rest.
Preferably, described feed mechanism comprises the handwheel be rotatably connected on frame, and handwheel is by rack and pinion drive mechanism drive shaft cover.
Preferably, described cutter is fixed on described knife rest by holding screw.
Preferably, described groove is bar-shaped trough.
Advantage and good effect that the present invention has are: knife rest can radially slide on cutterhead, the knife rest bottom is provided with removable pin and spring, under the effect of spring force, removable pin can contact with steel pipe inner wall all the time by groove, thereby guarantee to take the processing mode that the hot-expanding steel tube inwall is benchmark, in the situation that hot-expanding steel tube inner wall thickness to be processed is uneven or lose circle, also can guarantee the precision of steel pipe processing, improved the qualification rate of steel pipe processing.

The specific embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, the hot-expanding steel tube pipe end facing machine of the present embodiment, slidably connect collar bush 2 on frame 1, described collar bush 2 is driven by feed mechanism, be rotatably connected to main shaft 3 by bearing 13 in described collar bush 2, one end of described main shaft 3 is connected with drive motors 12, the other end leans out described collar bush 2 and by spline joint, one cutterhead 4 is arranged, cutterhead 4 is of a size of hot-expanding steel tube standard inner core size, cutterhead 4 can stretch in hot-expanding steel tube to be processed, and just be slidably matched with the steel pipe inner arm, described cutterhead 4 is provided with chute 5 near the end face of described frame 1, the periphery of described cutterhead 4 is provided with bar-shaped trough 6, and described bar-shaped trough 6 radially communicates with described chute 5, in described chute 5, being equipped with can be at the knife rest 7 of chute 5 interior movements, the bottom of described knife rest 7 is fixed with spring 8 and removable pin 9, described spring 8 is fixed in described chute 5, the free end of described removable pin 9 can lean out the periphery of described cutterhead 4 by bar-shaped trough 6, on described knife rest 7, cutter 10 for groove is installed, cutter 10 is fixed on knife rest 7 by holding screw, and cutter 10 can be loaded and unloaded as required.
Described feed mechanism comprises the handwheel 11 be rotatably connected on frame, and handwheel 11 is by rack and pinion drive mechanism drive shaft cover 2.
As shown in Figure 2, the hot-expanding steel tube of the present embodiment with pipe end facing machine in use, cutterhead 4 can be in the interior rotation of hot-expanding steel tube 14 to be processed, and be rotated with the cutter on movable knife disc 4, removable pin 9 contacts (A position as shown in Figure 2) by bar-shaped trough 6 with steel pipe 14 inwalls to be processed, because may existing, hot-expanding steel tube to be processed loses the circle phenomenon, cutterhead 4 can not be constantly and the steel pipe inner wall sliding-contact, but the elastic force effect due to spring 8, in process, the free end of removable pin 9 remains with steel pipe inner wall and contacts, certain and the removable pin 9 of the length of removable pin 9 is fixedly connected with knife rest 7, removable pin 9 can move (B position as shown in Figure 2) by band movable knife rack 7 in chute, thereby the inwall that has guaranteed in the steel pipe process to take all the time steel pipe 14 to be processed is benchmark, guaranteed the precision of steel pipe processing.
Above one embodiment of the present of invention are had been described in detail, but described content is only preferred embodiment of the present invention, can not be considered to for limiting practical range of the present invention.All equalization variations of doing according to the present patent application scope and improvement etc., within all should still belonging to patent covering scope of the present invention.
