Abstract
The utility model relates to the straight elbow pipe welding mould of a kind of spring locate mode, comprise die holder, mould bases, locating piece, straight tube cover rod, spring, blocking, spring in its natural state two ends is cylindrical, middle part is consistent with bend pipe shape, its one end is fixedly connected with the upper end of straight tube cover rod, and the other end is fixedly connected with blocking; The external diameter of straight tube cover rod and the internal diameter matched in clearance of welding straight tube; The middle part of spring and the internal diameter matched in clearance of bend pipe; Be provided with semicircle cambered surface below locating piece, and with blocking termination external diameter phase wedging.The utility model, by straight tube cover rod outside diameter and the matched in clearance of welding straight tube internal diameter, realizes the location of straight tube in weld mold; By the matched in clearance of external diameter in the middle part of spring and bend pipe internal diameter, realize the location of bend pipe in weld mold; By blocking termination external diameter and the locate mode of locating piece semicircle cambered surface phase wedging, the relative welding position between bend pipe and straight tube is determined.The utility model welding is without sideslip, dislocation, and convenient mounting and clamping, simple to operate.
Description
Technical field
The utility model relates to a kind of weld mold, particularly relates to the spring jig structure of a kind of straight tube and elbow pipe welding, belongs to mould design and manufacture technical field.
Background technology
In manufacturing process of pipe fitting, straight tube is a kind of common weldering Joining Technology with welding of bend pipe.Because bend pipe belongs to section tube, thus larger with the positioning difficulty of straight tube welding.During pure manual welding, the uncertainty of welding position is comparatively large, often occurs sideslip, dislocation, thus affects welding quality; During mould positioning welding, then clamping, dismantle loaded down with trivial details, operate extremely inconvenient.Therefore, people wish that a kind of dismounting is simple, accurate positioning, easy to operate straight elbow pipe welding mould, apply in tube manufacture technique.
Summary of the invention
The purpose of this utility model is to provide a kind of spring locate mode straight elbow pipe welding mould, solves the problems such as sideslip that the straight elbow pipe welding of tradition occurs, dislocation, clamping mould are loaded down with trivial details, inconvenient operation.
To achieve these goals, the utility model Bian gets following technical scheme and implements: the straight elbow pipe welding mould of a kind of spring locate mode, comprise die holder, mould bases, locating piece, straight tube cover rod, spring, blocking, described mould bases and the vertical upper plane being fixed on die holder of straight tube cover rod; Described locating piece is fixed on the side of mould bases, it is characterized in that:
Described spring in its natural state two ends is cylindrical, and middle part is consistent with bend pipe shape, and its one end is fixedly connected with the upper end of straight tube cover rod, and the other end is fixedly connected with blocking;
The external diameter of described straight tube cover rod and the internal diameter matched in clearance of welding straight tube;
The middle part external diameter of described spring and the internal diameter matched in clearance of bend pipe;
The diameter of described spring wire is less than 3mm;
Be provided with semicircle cambered surface below described locating piece, and with blocking termination external diameter phase wedging.
The utility model is by straight tube cover rod outside diameter and the matched in clearance of welding straight tube internal diameter, realize the location of straight tube in weld mold, by the matched in clearance of spring outer diameter and bend pipe internal diameter, realize the location of bend pipe in weld mold, and by the locate mode of blocking termination external diameter with locating piece semicircle cambered surface phase wedging, relative welding position between bend pipe and straight tube is determined, thus for welding procedure prevent sideslip, dislocation laid accurate location base, and convenient mounting and clamping, simple to operate, the welding quality of straight tube and bend pipe can be guaranteed.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of A-A cross section in accompanying drawing 1.
In attached Fig. 1 and 2: 1 die holder, 2 straight tube cover rods, 3 welding straight tubes, 4 springs, 5 welding bend pipes, 6 locating pieces, 7 blockings, 8 mould bases.
Detailed description of the invention
Below in conjunction with accompanying drawing the utility model is further explained illustrate:
As shown in accompanying drawing 1,2, mould bases 8 and straight tube cover rod 2 are vertically fixed on the upper plane of die holder 1; Locating piece 6 is fixed on the side of mould bases 8; Spring 4 in its natural state two ends is cylindrical, and middle part is consistent with welding bend pipe 5 shape, and its one end is fixedly connected with the upper end of straight tube cover rod 2, and the other end is fixedly connected with blocking 7, and the diameter of spring wire is less than 3mm; The external diameter of straight tube cover rod 2 and the internal diameter matched in clearance of welding straight tube 3; Middle part external diameter and the internal diameter matched in clearance of welding bend pipe 5 of spring 4; Be provided with semicircle cambered surface below locating piece 6, and with the termination external diameter phase wedging of blocking 7.
During straight elbow pipe welding, successively one end that welding straight tube 3 is equipped with blocking 7 from spring 4 is inserted on straight tube cover rod 2, realizes the location of welding straight tube 3; Welding bend pipe 5 is inserted in the middle part of spring 4, and one end of welding bend pipe 5 is leant with the upper end of welding straight tube 3, realize the location of welding bend pipe 5; Then Compress Spring 4 to blocking 3 is wedged in the semicircle cambered surface below locating piece 6, then is welded by two pipes with welding gun.After welding terminates, Compress Spring 4 makes blocking 7 throw off locating piece 6, and spring 4 is in servo-actuated state, can take out integrally welded straight bend pipe from spring 4 and straight tube cover rod 2.
