Abstract
The utility model relates to the technical field of machinery, in particular to a sizing die for machining an elbow. The sizing die for machining the elbow comprises a sizing die body. A transverse groove is formed in the middle of the sizing die body, the upper surface of the middle of the transverse groove is connected with one end of a longitudinal groove, the other end of the longitudinal groove is formed in the upper side edge of the sizing die body, the lower surface of the middle of the transverse groove is connected with one end of an inclined groove, the other end of the inclined groove is arranged at the lower side edge of the sizing die body, and the included angle between the central line of the transverse groove and the central line of the inclined groove is 78 degrees. Compared with the prior art, the sizing die structure special for the elbow is adopted, so that after the elbow is formed, correction of the shape and the size is conducted, and therefore the performance of the finished elbow is improved.
Description
Technical field
The utility model relates to field of mechanical technique, specifically a kind of sizing die of processing elbow.
Background technology
At present, in the elbow process, exist production efficiency low, the problem that the end properties produced is poor.Now, in order to enhance productivity and end properties, the bend forming upper die and lower die have been designed.But the elbow after moulding can't carry out the correction of shape and size.Therefore, the sizing die that designs a kind of processing elbow of the correction that can carry out shape and size is vital.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of sizing die of processing elbow of the correction that can carry out shape and size is provided.
In order to achieve the above object, the utility model has designed a kind of sizing die of processing elbow, comprise the sizing die body, it is characterized in that: the middle part of sizing die body is provided with transverse concave groove, the upper surface at transverse concave groove middle part is connected with an end of longitudinal fluting, the other end of longitudinal fluting is located at the upper side edge of sizing die body, the lower surface at transverse concave groove middle part is connected with an end of inclined groove, the other end of inclined groove is located at the lower side of sizing die body, and the angle between the center line of transverse concave groove and the center line of inclined groove is 78 °.
The upper right corner of described sizing die body and the lower left corner respectively are provided with a through hole.
The cross section of described transverse concave groove is semicircle, and diameter is 20 millimeters.
The cross section of described longitudinal fluting is semicircle, and diameter is 32 millimeters.
The utility model compared with the existing technology, adopts the sizing die structure that is exclusively used in elbow, makes elbow can carry out the correction of shape and size after moulding, thereby the end properties of elbow is improved.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is side view of the present utility model.
Referring to Fig. 1 and Fig. 2,1 is the sizing die body; 2 is through hole; 3 is longitudinal fluting; 4 is transverse concave groove; 5 is inclined groove.
The specific embodiment
Now by reference to the accompanying drawings the utility model is described further.
Referring to Fig. 1 and Fig. 2, the utility model has designed a kind of sizing die of processing elbow, comprises the sizing die body.The middle part of sizing die body 1 is provided with transverse concave groove 4, the upper surface at transverse concave groove 4 middle parts is connected with an end of longitudinal fluting 3, the other end of longitudinal fluting 3 is located at the upper side edge of sizing die body 1, the lower surface at transverse concave groove 4 middle parts is connected with an end of inclined groove 5, the other end of inclined groove 5 is located at the lower side of sizing die body 1, and the angle between the center line of the center line of transverse concave groove 4 and inclined groove 5 is 78 °.
In the utility model, for the ease of fixing, the upper right corner of sizing die body 1 and the lower left corner respectively are provided with a through hole 2.In order to meet better elbow shaping requirement, the Cross section Design of transverse concave groove 4 is semicircle, and diameter is designed to 20 millimeters.The Cross section Design of longitudinal fluting 3 is semicircle, and diameter is designed to 32 millimeters.
The utility model, when work, is put into the elbow of moulding the groove of sizing die body 1, carries out the correction of elbow shape and size, thereby the end properties of elbow is improved.
