Abstract
The utility model discloses a reducing elbow die and mainly aims at solving the problems that the existing reducing elbow processing technology is complicated and the processing efficiency is low. The reducing elbow die is characterized in that a die body (1) is formed by the buckling of two equally divided bodies, a straight hole section (2) and an arc hole section (3) of which the inner diameter gradually reduces are arranged on the die body (1), the straight hole section (2) is in clearance fitting with the outer diameter of a pipe blank (4), and the straight hole section (2) is smoothly transited to the arc hole section (3). The reducing elbow die has the advantages of simple structure, convenience in use, simplified processing technology and high processing efficiency.
Description
Technical field
The utility model relates to a kind of pipe fitting, is specifically related to a kind of reducing elbow mould.
Background technology
Elbow is the pipe fitting that changes the pipeline direction, be divided into 45 °, 90 ° and 180 ° three kinds by angle the most frequently used, also comprise other improper angle elbows such as 60 ° of grades according to requirement of engineering in addition, be used for connecting two pipes that inside nominal diameter is identical or different, pipeline is turned at an angle.In order to satisfy the needs of some occasions, the normal reducing elbow that adopts, namely the public footpath diameter of the large other end of nominal diameter of an end is little, and this reducing elbow generally is to process by modes such as casting, punching press, butt welding, has the defectives such as processing technology is complicated, working (machining) efficiency is low.
The utility model content
In order to overcome existing reducing elbow processing technology complexity and the low deficiency of working (machining) efficiency, the utility model provides a kind of reducing elbow mould, and this reducing elbow mode structure is simple, easy to use, has simplified processing technology, and working (machining) efficiency is high.
The technical solution of the utility model is: a kind of reducing elbow mould, comprise mold, mold is that the two bodies fastening of five equilibrium forms, mold is provided with straight hole section and the diminishing circular hole section of internal diameter, the straight hole section cooperates with the crest clearance of pipe spare, rounding off between straight hole section and the circular hole section.
Described circular hole section is 90 °.
The utlity model has following beneficial effect: owing to taking such scheme, this mould and forcing press are used in conjunction with, and pipe spare is under the effect of mold, and flexural deformation forms reducing elbow, opens mold, takes out reducing elbow, finishes process.This mould structure is simple, and is easy to use, simplified processing technology, and working (machining) efficiency is high.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
1-mold among the figure, 2-straight hole section, 3-circular hole section, 4-pipe spare, 5-steel ball.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, a kind of reducing elbow mould comprises mold 1, and mold 1 forms for the two bodies fastening of five equilibrium, and mold 1 is provided with straight hole section 2 and the diminishing circular hole section 3 of internal diameter, straight hole section 2 cooperates with the crest clearance of pipe spare 4, rounding off between straight hole section 2 and the circular hole section 3.Owing to taking technique scheme, this mould and forcing press are used in conjunction with, with pipe spare 4(straight tube) insert from the straight hole section 2 of mold 1, then place steel ball 5 at pipe spare 4, the internal diameter of the external diameter of steel ball 5 and straight hole section 2 and circular hole section 3 is complementary, be pressed into steel ball 5 with forcing press, steel ball 5 is stuck in the end face of pipe spare 4, pipe spare 4 is compressed into circular hole section 3 fully from straight hole section 2, pipe spare 4 under the effect of mold 1, flexural deformation, form reducing elbow, open mold 1, take out reducing elbow, finish process.This mould structure is simple, and is easy to use, simplified processing technology, and working (machining) efficiency is high.
Described circular hole section 3 is 90 °.Circular hole section 3 also can be designed to other angle as required.
Claims (2)
1. reducing elbow mould, comprise mold (1), it is characterized in that: mold (1) forms for the two bodies fastening of five equilibrium, mold (1) is provided with straight hole section (2) and the diminishing circular hole section of internal diameter (3), straight hole section (2) cooperates with the crest clearance of pipe spare (4), rounding off between straight hole section (2) and the circular hole section (3).
2. reducing elbow mould according to claim 1, it is characterized in that: circular hole section (3) is 90 °.
