Description

The molding assistant ejector pin in short tube end
Technical field
The utility model is related to short tube production technical field, especially a kind of molding assistant ejector pin in short tube end.
Background technology
In the forming process of ultrashort pipe fitting double end end, pipe fitting endoporus needs plug to support, and end face needs reliable location.It is existing The other end is reprocessed after current way is one end molding, is divided into two procedures, long processing time, and dimensional stability also not It is high.
Utility model content
The technical problems to be solved in the utility model is:It overcomes the deficiencies in the existing technology, provides a kind of to pipe fitting endoporus It is supported, end face is positioned, and cooperation punch carries out the molding assistant ejector pin in short tube end of time processing.
Technical solution adopted by the utility model to solve its technical problems is:A kind of molding auxiliary top in short tube end Bar, including shaft shoulder screw, sliding plug, pipe end positioning sleeve, spring and auxiliary rod, the shaft shoulder screw sequentially pass through slide cores Stick, spring and pipe end positioning sleeve, and connect with auxiliary rod, the internal diameter of pipe end positioning sleeve one end is more than the straight of sliding plug Diameter, the internal diameter of the other end are matched with the outer diameter of shaft shoulder screw, and one end that the auxiliary rod is connected with shaft shoulder screw opens up There are stepped hole, the inner wall of stepped hole to be equipped with and the matched internal thread of shaft shoulder screw terminal part external screw thread.
It further limits, the spring is set on shaft shoulder screw, one end and the pipe end positioning sleeve inner face phase of spring It supports, the spring other end and the inner side end of sliding plug are in close contact.
It further limits, the pipe end positioning sleeve has annular projection portion.
It further limits, anti-skid design is provided on the auxiliary rod peripheral surface.
The utility model has the beneficial effects that:The assistant ejector pin of the utility model can be supported pipe fitting endoporus, end face It is positioned, cooperation punch carries out time processing to ultrashort pipe fitting, substantially increases processing efficiency, dimensional stability also obtains greatly Width improves.
Description of the drawings
The utility model is further illustrated with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1. shaft shoulder screws, 2. sliding plugs, 3. pipe end positioning sleeves, 4. springs, 5. auxiliary rods, 3-1. annular projections Portion.
Specific implementation mode
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram only to show Meaning mode illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
As shown in Figure 1, a kind of molding assistant ejector pin in short tube end of the present embodiment, including shaft shoulder screw 1, sliding plug 2, pipe end positioning sleeve 3, spring 4 and auxiliary rod 5, shaft shoulder screw 1 sequentially pass through sliding plug 2, spring 4 and pipe end positioning sleeve 3, and It is connect with auxiliary rod 5, the internal diameter of 3 one end of pipe end positioning sleeve is more than the diameter of sliding plug 2, internal diameter and the shaft shoulder spiral shell of the other end The outer diameter of nail 1 matches, and one end that auxiliary rod 5 is connected with shaft shoulder screw 1 offers stepped hole, and the inner wall of stepped hole is equipped with With the 1 matched internal thread of terminal part external screw thread of shaft shoulder screw.
In the present embodiment, spring 4 is set on shaft shoulder screw 1, one end and the 3 inner face phase of pipe end positioning sleeve of spring 4 It supports, 4 other end of spring and the inner side end of sliding plug 2 are in close contact.
In the present embodiment, pipe end positioning sleeve 3 has annular projection portion 3-1.
In this embodiment, it is provided with anti-skid design on 5 peripheral surface of auxiliary rod.
Shaft shoulder screw 1 is used for assembly connection, and sliding plug 2 plays the role of support tubes endoporus, is rushed at the time of molding Head plug ejection, easy-unloading, pipe end positioning sleeve 3, especially annular projection portion 3-1 avoid pipe fitting from beating for positioning pipe fitting end face It is sliding to retreat;Spring 4 is for resetting sliding plug 2, and auxiliary rod 5 is for taking and being put into pipe fitting use.
The above embodiment is only the technical concepts and features for illustrating the utility model, and its object is to allow be familiar with this skill The personage of art can understand the content of the utility model and be implemented, and the protection model of the utility model can not be limited with this It encloses, it is all according to equivalent change or modification made by the spirit of the present invention essence, it should all cover the protection model in the utility model In enclosing.
