Abstract
The utility model relates to the technical field of machinery, in particular to a puncher pin of a drum type tee joint. The puncher pin of the drum type tee joint comprises a puncher pin body and is characterized in that the left side of the puncher pin body and the right side of the puncher pin body are both planes, the upper side of the puncher pin body and the lower side of the puncher pin body are kidney-shaped cylinders with arc surfaces, and a through hole is formed in the center of the puncher pin body. Compared with the prior art, the puncher pin special for the drum type tee joint has the advantages of being formed in a one-time mode, simple in structure, fast to use, easy to operate, and capable of greatly improving production efficiency.
Description
Technical field
The utility model relates to field of mechanical technique, specifically the general drift of a kind of cydariform three.
Background technology
Tradition is complicated for the manufacturing procedure of cydariform threeway, and wastes time and energy, and the semi-finished product after preprocessing need to be carried out to follow-up loaded down with trivial details step and be processed into and meet the requirements of finished product, and productive temp does not catch up with client's demand.
Summary of the invention
The utility model is for overcoming the deficiencies in the prior art, and a kind of special drift of producing for the cydariform threeway is provided, can one-shot forming, and simple, fast, and simple to operate, greatly enhance productivity.
For achieving the above object, design the general drift of a kind of cydariform three, comprise drift, it is characterized in that: drift is that the left and right sides is plane, and upper and lower both sides are the kidney-shaped cylinder of arc surface, and the central authorities of drift are provided with through hole.
Described through hole is the narrow stepped through hole of upper side wider downside.
The upper surface that is positioned at the drift of close drift arc surface is provided with chamfering.
Angle between described chamfering and drift upper surface is 61.4 °.
The utility model compared with the existing technology, provides a kind of special drift of producing for the cydariform threeway, can one-shot forming, and simple, fast, and simple to operate, greatly enhance productivity.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 be in Fig. 1 A-A to cutaway view.
Referring to Fig. 1, Fig. 2,1 is through hole, and 2 is chamfering, and 3 is drift.
The specific embodiment
Below with reference to the accompanying drawings the utility model is described further.
As Fig. 1, shown in Fig. 2, drift 3 is for the left and right sides is plane, and upper and lower both sides are the kidney-shaped cylinder of arc surface, and the central authorities of drift 3 are provided with through hole 1.
Through hole 1 is the narrow stepped through hole of upper side wider downside.
The upper surface that is positioned at the drift 3 of close drift 3 arc surfaces is provided with chamfering 2.
Angle between chamfering 2 and drift 3 upper surfaces is 61.4 °.
During work, semi-finished product after preprocessing are positioned over to the below of drift 3, drift 3 is connected with press by connecting axle, the workman only need control press and can complete half-finished punching press, one-shot forming, simply, fast, and the quality of the product of producing can reach unanimously, greatly enhances productivity.
