Abstract
The utility model relates to the technical field of machinery, in particular to a puncher pin for machining a 90-degree elbow. The puncher pin for machining the 90-degree elbow comprises a puncher pin body, arc-shaped hook faces, sector-shaped side faces and threaded holes. The lower surface of a beam of the puncher pin body is provided with one arc-shaped hook face, the front side of the puncher pin body and the rear side of the puncher pin body are respectively provided with one sector-shaped side face, the surface of the lower side of each sector-shaped side face is provided with the other arc-shaped hook face, the bottom of the inner side of the sector-shaped side face is provided with a circular bead structure, and the four vertically-downward threaded holes are formed in the upper surface of the beam of the puncher pin body. Compared with the prior art, the puncher pin for machining the 90-degree elbow has the advantages that the structure of the puncher pin is changed, the sector-shaped side faces and the arc-shaped hook faces are additionally arranged so that the radius of each arc-shaped hook face can be optimized, therefore, when extrusion is conducted on a circular pipe by the puncher pin, the radian degree requirement of circular pipe machining is satisfied, and the problems of surface damage and even rejection of the circular pipe in the process of machining are solved.
Description
Technical field
The utility model relates to field of mechanical technique, specifically the drift of 90 ° of elbows of a kind of processing.
Background technology
Add man-hour carrying out 90 ° of elbows, the lower surface of the general drift used all is plane.The drift on plane, when the extrusion process to pipe, generally adopts the extruding angle of mechanical control break drift, thereby realizes the radian demand of pipe.But the drift on plane, in the extrusion process to pipe, not only can't accurately meet the radian demand of pipe, also may cause surface damage, even scrap because unbalance stress causes pipe.Therefore, design and a kind ofly can prevent that the drift of 90 ° of elbows of processing of pipe damage from being vital.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of drift that can prevent 90 ° of elbows of processing of pipe damage is provided.
In order to achieve the above object, the utility model has designed the drift of 90 ° of elbows of a kind of processing, comprise drift body, arc-shaped curved surface, fan-shaped side and screwed hole, it is characterized in that: the lower surface of drift body crossbeam is provided with arc-shaped curved surface, before and after the drift body, both sides are provided with fan-shaped side, the downside surface of fan-shaped side is provided with another arc-shaped curved surface, and the inside bottom of fan-shaped side is provided with fillet structure, and the upper surface of drift body crossbeam is provided with four screwed holes straight down.
The radius of described fillet structure is 5 millimeters.
The radius of described arc-shaped curved surface is 215 millimeters.
The radius of described another arc-shaped curved surface is 457 millimeters.
The utility model compared with the existing technology, changed the structure of drift, set up fan-shaped side and arc-shaped curved surface and optimized the radius of arc-shaped curved surface, make drift in the process that pipe is pushed, meet the radian requirement of pipe processing, the surface damage of also having avoided pipe to cause in process, the problem of even scrapping.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The A-A cutaway view that Fig. 2 is Fig. 1 of the present utility model.
Referring to Fig. 1,1 is the drift body; 2 is fan-shaped side; 3 is screwed hole; 4 is arc-shaped curved surface; 5 is another arc-shaped curved surface.
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 comprises drift body, arc-shaped curved surface, fan-shaped side and screwed hole.The lower surface of drift body 1 crossbeam is provided with arc-shaped curved surface 4, drift body 1 both sides, front and back are provided with fan-shaped side 2, the downside surface of fan-shaped side 2 is provided with another arc-shaped curved surface 5, the inside bottom of fan-shaped side 2 is provided with fillet structure, and the upper surface of drift body 1 crossbeam is provided with four screwed holes 3 straight down.
In the utility model, in order further to have avoided pipe, in process, cause surface damage, the radius of fillet structure is 5 millimeters.The radius of arc-shaped curved surface 4 is 215 millimeters.The radius of another arc-shaped curved surface 5 is 457 millimeters.
The utility model, when work, after the screwed hole of processing equipment and drift body 13 is fixed, carries out extrusion process to pipe.
The utility model has changed the structure of drift body 1, set up fan-shaped side 2, arc-shaped curved surface 4 and another arc-shaped curved surface 5 and optimized the radius of arc-shaped curved surface 4 and another arc-shaped curved surface 5, make drift body 1 in the process that pipe is pushed, meet the radian requirement of pipe processing, the surface damage of also having avoided pipe to cause in process, the problem of even scrapping.
