Description

A kind of stem reducing mould of pipe inner position
Technical field
The present invention relates to industrial machinery application, especially relate to a kind of stem reducing mould of pipe inner position.
Background technology
Add man-hour carrying out undergauge to tubing, usually tubing can be put in the processing mold be made up of inner mold and outer mold, by driving the diameter of inner mold to change to the change of the diameter of tubing at outer mold operation pressure.
Processing method of the prior art, tubing directly can be put in inner mold, when applying pressure can there is the change of body in inevitable tubing, cause producing skew, and tubing after processing change place of diameter again can have comparatively significantly folding line, need the grinding process in later stage, considerably increase the expenditure of time of processing.
Summary of the invention
In view of the defect that above-mentioned prior art exists, the object of the invention is the stem reducing mould proposing a kind of pipe inner position.
Object of the present invention will be achieved by the following technical programs: a kind of stem reducing mould of pipe inner position, comprise: pressurizing mold, described pressurizing mold is provided with the cavity of accommodating tubing, it is characterized in that, one end of described pressurizing mold is fixed with the first positioning core, described first positioning core comprises the first fuse and the first Access Division, described first fuse is positioned on the axis of described pressurizing mold, the second positioning core is provided with at the opposite side of described pressurizing mold, second fuse of the second positioning core under static state and the axis of described pressurizing mold have angle, described second fuse is in working order positioned on the axis of described pressurizing mold.
Preferably, the stem reducing mould of above-mentioned a kind of pipe inner position, described second positioning core is connected on elastic reseting part, and described elastic reseting part is installed on stem reducing mould.
Preferably, the stem reducing mould of above-mentioned a kind of pipe inner position, described first fuse and in working order under described second fuse be resisted against on the inwall of tubing.
Outstanding effect of the present invention is: by arranging the first fuse and the second fuse in tubing, tubing is positioned, be convenient in process, remain the fixing of position, first fuse and the second fuse are resisted against on the inwall of tubing simultaneously, when changing the diameter of tubing of certain part, first fuse and the second fuse can be played a supporting role for the part without the need to changing diameter, the pipe diameter of processing is clearly demarcated, second positioning core is connected to elastic reseting part, when needs add man-hour to tubing, elastic reseting part is launched on the axis of pressurizing mold, when without the need to working, idle state can be in, tubing is convenient to put in pressurizing mold, increase the flexibility of operation.
Below just accompanying drawing in conjunction with the embodiments, is described in further detail the specific embodiment of the present invention, is easier to understand, grasp to make technical solution of the present invention.
Accompanying drawing explanation
Fig. 1 is the stem reducing mould structural representation of a kind of pipe inner position that embodiments of the invention provide.
Detailed description of the invention
As shown in Figure 1, the stem reducing mould of a kind of pipe inner position of the present embodiment, comprise: pressurizing mold 1, pressurizing mold 1 is provided with the cavity 2 of accommodating tubing, one end of pressurizing mold 1 is fixed with the first positioning core 3, first positioning core 3 comprises the first fuse 301 and the first Access Division 302, first fuse 301 is positioned on the axis of pressurizing mold 1, the second positioning core 4 is provided with at the opposite side of pressurizing mold 1, second fuse 401 of the second positioning core 4 under static state has angle with the axis of pressurizing mold 1, the second fuse 401 is in working order positioned on the axis of pressurizing mold 1.
First fuse 301 and in working order under the second fuse 401 be resisted against on the inwall of tubing.
First positioning core 3 and the second positioning core 4, can position tubing, be convenient in process, remain the fixing of position, first fuse 301 and the second fuse 401 are resisted against on the inwall of tubing simultaneously, when changing the diameter of tubing of certain part, first fuse 301 and the second fuse 401 can be played a supporting role for the part without the need to changing diameter, and the pipe diameter change of processing is clearly demarcated.
Second positioning core 4 is connected on elastic reseting part 5, and elastic reseting part 5 is installed on stem reducing mould.Wherein, elastic reseting part 5 is spring leaf, can cause the change of flexibility, driving the second positioning core 4 to move when changing the pressure of spring leaf.
Second positioning core 4 is connected to elastic reseting part 5, and when needs add man-hour to tubing, elastic reseting part 5 is launched on the axis of pressurizing mold 1, when without the need to working, can idle state be in, be convenient to tubing be put in pressurizing mold 1, increase the flexibility of operation.
When under idle state, elastic reseting part 5 is in a case of bending, and under this state, the second positioning core 4 remains static, and its second fuse 401 has angle with the axis of pressurizing mold 1, and this angle is acute angle, right angle or obtuse angle.Need to add man-hour to tubing, tubing is put in cavity 2, abut on the first fuse 301 of the first positioning core 3, the second positioning core 4 is changed its state simultaneously, together tubing is blocked location with the first positioning core 3, carry out the processing of diameter.
The present invention still has numerous embodiments, all employing equivalents or equivalent transformation and all technical schemes formed, and all drops within protection scope of the present invention.
