Abstract
The invention relates to an elbow die for the production of seamless punched elbows. The elbow die comprises an upper semicircular die and a lower semicircular die. Each of the upper semicircular die and the lower semicircular die is provided with a half elbow cavity in the shape as a finished elbow. The elbow die is characterized in that the outside width of the upper semicircular die is equal to the diameter of the elbow cavities, the outer side of the lower semicircular die is provided with an extension segment, the length of the extension segment is larger than the radius of the elbow cavities, and the upper semicircular die can be pressed into the lower semicircular die. The elbow die has the advantages that elbow punching cost can be reduced, production process of punched elbows is simplified, and production efficiency is increased.
Description
Technical field
The present invention relates to a kind of elbow module, relate in particular to a kind of seamless punched bend production elbow module.
Background technology
Elbow is the connector of pipe fitting, pipeline, is used for changing pipeline pumped (conveying) medium flow direction, and elbow can be divided into seamless by used raw material difference and seam arranged, and seamlessly typically refers to the direct pushing of steel pipe (can be seamless pipe or ERW) or is stamped to form.At present, pipe is crushed the production method of seamless punched bend in the punching course to avoid in order earlier to fill in ship type Internal core mould in pipe, and then pipe is put into the circular metal elbow module is stamped to form; Wherein elbow module comprises that upper semi-circle mould and lower semi-circular mould form, and the upper semi-circle mould is identical with the outside width of lower semi-circular mould, and the identical elbow cavity of shape of half finished product elbow is respectively arranged in upper semi-circle mould and the lower semi-circular mould; The size of this Internal core mould is decided according to the different size of pipe internal diameter, makes the elbow of same outer diameter as, different wall thus, just needs to be equipped with the Internal core mould of different size, and this has increased the cost of elbow punching press undoubtedly greatly.
Summary of the invention
At above problem, the object of the present invention is to provide a kind of seamless punched bend production elbow module that can reduce the cost of elbow punching press.
Technology contents of the present invention is: a kind of seamless punched bend production elbow module, comprise upper semi-circle mould and lower semi-circular mould, and in upper semi-circle mould and the lower semi-circular mould elbow cavity identical with the shape of finished product elbow arranged respectively half; The outside width that it is characterized in that the upper semi-circle mould is identical with the diameter of elbow cavity, is provided with an extension in the outer side edges of lower semi-circular mould, and the length of extension is the radius more than or equal to the elbow cavity; The upper semi-circle mould can be pressed in the lower semi-circular mould.
When producing seamless punched bend with seamless punched bend production of the present invention with elbow module, only need the steel pipe material is carried out cutting stock, get trapezoidal pipe; Trapezoidal pipe being put into stove heating back flattens again; The trapezoidal pipe of Ya Bianing is put into the metal bends mould punching press seamless punched bend that gets product at last;
The advantage that the present invention compared with prior art has is: mould of the present invention need not add ship type Internal core mould in pipe when producing, greatly reduce the cost of elbow punching press thus, has strengthened product competitiveness; In the elbow-punching forming process, the lower semi-circular mould can wrap the upper semi-circle mould fully, avoids pipe to flatten; The technology that the present invention produces seamless punched bend is simple, has improved production efficiency.

Fig. 3 is structural representation of the present invention.
Fig. 4 is the left view of Fig. 3.
The specific embodiment
As depicted in figs. 1 and 2, the circular metal elbow module is made up of upper semi-circle mould 1 and lower semi-circular mould 2 in the prior art, upper semi-circle mould 1 is identical with the outside width of lower semi-circular mould 2, and the identical cavity 3 of shape of half finished product elbow is respectively arranged in upper semi-circle mould 1 and the lower semi-circular mould 2; When punched bend, need in pipe 4, fill in ship type Internal core mould 5.
As shown in Figure 3 and Figure 4, a kind of seamless punched bend production elbow module comprises upper semi-circle mould 6 and lower semi-circular mould 7, in upper semi-circle mould 6 and the lower semi-circular mould 7 the elbow cavity 8 identical with the shape of finished product elbow is arranged respectively half; The outside width that it is characterized in that upper semi-circle mould 6 is identical with the diameter of elbow cavity 8, is provided with an extension 7.1 in the outer side edges of lower semi-circular mould 7, and the length of extension 7.1 is the radius more than or equal to elbow cavity 8; Upper semi-circle mould 6 can be pressed in the lower semi-circular mould 7.
Claims (1)
