Abstract
The utility model provides a punching and shearing die which is suitable for the intersecting line of a metal thin wall pipe, comprising a punching head and a lower die, wherein, the punching head forms a cylinder which has an inclined plane and an acute cutting edge; the lower die is provided with a die hole into which the punching head is inserted; the wall of the die hole is provided with a feed opening which forms a certain angle theta with the punching and shearing direction of the punching head. So long as the thin wall pipes are concerned, supply dies can be designed, and satisfactory intersecting lines can be punched and sheared according to the diameter, the wall thickness, and the intersecting angle of each of two pipes. Being suitable for intersecting line processing for various pipes, the utility model has the advantages that production efficiency of the utility model is increased by scores of times than that of the milling method, an incision is smooth and level, burr is not present, and a pipe orifice is not deformed.
Description
The utility model relates to the processing of metal pipe material, especially a kind of light-wall pipe intersection punching and shearing die.
The non-headtotail of metal pipe material adopted pipe joint more and directly tubing was welded into certain angle, or processed the method for welding after certain intersection shape with milling machine in the past, and these method work efficiency are very low, and interface is yielding.
The purpose of this utility model is to provide a kind of production efficiency height, otch smooth smooth, the mould of the processing thin-walled tubing of the indeformable punching of pipe fitting.
The utility model is achieved in that according to the pipe diameter and the wall thickness of need processing, passes through angle mutually
, selected punch diameter, drift is the Cylinder of inclined-plane, sharp cutting edge, and counterdie has a nib for the drift insertion, and the nib wall has and drift punching direction forms certain angle
Charging hole, the lower edge of charging aperture is the counterdie cutting edge.The tubing of need punching intersection is inserted in the charging hole, but just punching goes out satisfactory intersection.
Elaborate below in conjunction with accompanying drawing.
Fig. 1 is a structural representation of the present utility model.Fig. 2 is a cutaway view.
This mould is to adopt the punching processing mold, on punch press or other similar equipment, implements, so long as thin-wall pipes, and can be according to diameter, the wall thickness of two pipes, pass through angle mutually, design corresponding mould, punching goes out satisfactory intersection.Drift (1) is a Cylinder, is inclined-plane, sharp cutting edge towards sword (2), can select the diameter of drift as requested, and bed die (3) has a nib (4) for the drift insertion, and the nib wall has and drift punching direction forms certain angle
Charging hole (5), the charging hole diameter matches with the pipe diameter that needs processing, the lower edge of charging aperture is counterdie cutting edge (6).
In inserting charging hole (5), the punching direction shape of its center line and drift at an angle according to Q for the tubing (workpiece 7) of need punching intersection
The topmost of tubing can not be collided with drift (1), promptly locate with the G point, when drift (1) when moving downward, its cutting edge (2) under the cooperation of counterdie cutting edge (6) is being gone out the intersection below the workpiece centre plane, ° installation of tubing Rotate 180, just can partly go out all the other of intersection.Charging hole can change according to the requirement of need workpiece
And obtain different intersection shapes.
Use this mould punching thin-wall pipes intersection, production efficiency improves tens times than milling method, and otch is smooth smooth, no burr, and the mouth of pipe is indeformable. This mould is applicable to the intersection line processing of various tubing, is used for processing bicycle tripod tubing and woman style big curved Beam car U-shaped pipe texts is ideal.
Claims (2)
1, a kind of light-wall pipe intersection punching and shearing die is made of drift and counterdie, it is characterized in that:
A, drift are Cylinder shape, are inclined-plane, sharp cutting edge towards sword;
B, counterdie have a nib for the drift insertion, and the nib wall has the charging hole that forms certain angle θ with drift punching direction.
2, mould as claimed in claim 1, the lower edge that it is characterized in that charging aperture is the counterdie cutting edge.
