Abstract
The utility model discloses a core rod for preparing metal pipe fittings. The core rod for preparing metal pipe fittings is characterized in that one end of the core rod is provided with a core head, the core head includes two metal plates, one end of every metal plate is connected with the core rod, and the other end of every metal is connected to each other to form an acute angle. The core rod for preparing metal pipe fittings is convenient for machining and using.
Description
Technical field
The utility model relates to a kind of part that is used on the metal tube process equipment, is specifically related to a kind of core bar.
Background technology
Need to use core bar in the metal tube process, core bar is enclosed within the base pipe, is used for the shaping of pipe fitting endoporus.Conventional core bar is common cylindrical stock, and the core bar two ends are puts down mouth, needs alignment earlier then at suit when suit base pipe, comparatively consuming time and use inconvenience.
The utility model content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and the core bar that is used to make metal tube that provides a kind of convenient processing to use.
The technical scheme in the invention for solving the above technical problem is: this is used to make the core bar of metal tube, it is characterized in that: described core bar one end is provided with core print, core print comprises two metallic plates, one end of two metallic plates is connected with core bar, and the other end is connected to each other and forms an acute angle.
Core print described in the utility model is welded on the core bar.
The utility model compared with prior art has the following advantages: the core bar head is provided with the core print of tip-angled shape, when suit base pipe, because the core bar head is not only sharp but also little, is very easy to aim at and suit, has made things convenient for processing to use and has also shortened process time.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model structure vertical view.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model comprises core bar 1 and core print 2, and described core bar 1 is a cylindrical bar, and one of core bar 1 is welded with core print 2.Described core print 2 comprises that an end of 3, two metallic plates 3 of metallic plate of two rectangles all welds with core bar 1, and the other end of two metallic plates 3 welds mutually, and the angle of two metallic plate 3 formation is an acute angle, and generally this angle is about 30 degree.
Above content described in this specification only is to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment; only otherwise depart from structure of the present utility model or surmount the defined scope of these claims, all should belong to protection domain of the present utility model.
Claims (2)
