Abstract
The utility model discloses a quick change type radiator pipe drawing-bulging assembly, and relates to a radiator pipe drawing-bulging assembly. The quick change type radiator pipe drawing-bulging assembly aims to solve the problems that a bulging head and a bulging rod of an existing drawing-bulging assembly are inconvenient and slow to connect, the big diameter of the bulging head cannot be always perpendicular to the axis of a radiator pipe, and machining quality cannot be guaranteed. A T-type hanging piece is of a structural form that two segments are made into a whole, the left end of the T-type hanging piece is of a cylindrical structure, and the right end of the T-type hanging piece is of a frustum-shaped structure. The T-shaped hanging piece is provided with an axial hole and further provided with a radial groove, wherein the radial groove and the axial hole are communicated to form a T-shaped structure. The bulging head is connected with the left end of the T-type hanging piece through a first screw, the bulging rod is connected with the right end of the T-type hanging piece through a second screw, and a connector is further installed between the bulging rod and the T-type hanging piece. The head of the second screw is placed in the radial groove. The diameter of the T-type hanging piece and the diameter of the connector are smaller than the diameter of the bulging head. The diameter of the bulging rod is smaller than the diameter of the T-type hanging piece and the diameter of the connector. The quick change type radiator pipe drawing-bulging assembly is mainly used on pipe penetration and pipe bulging production lines.
Description
Technical field
The utility model relates to a kind of radiating tube and draws swollen assembly, is specifically related to a kind of quick change formula radiating tube and draws swollen assembly.
Background technology
The expansion tube method that people adopt at present has manual and automatic two kinds.Manual expansion tube method is that the expander roll with swollen ball is inserted and treats to swell in swollen type pipe, then extract expander roll out, this method is because aim at expander roll to treat swollen type pipe by artificial experience, and slightly deviation just needs again to aim at expand tube, thereby labour intensity is large and production efficiency is lower.Automatically the fast Functionality, quality and appealing design of speed of production, is applicable to producing in enormous quantities.
Existingly draw swollen assembly to have following defect:
1, swollen head is connected inconvenient, not quick with expander roll;
2, the large footpath of swollen head cannot be vertical with radiating tube axis all the time, cannot guarantee crudy;
3, in drawing swollen process, draw swollen assembly easily radiating tube inner surface to be caused to damage.
Utility model content
The utility model is connected inconvenience in order to solve the existing swollen head of swollen assembly that draws with expander roll, not quick, the large footpath of swollen head cannot be vertical with radiating tube axis all the time, cannot guarantee the problem of crudy, and then provide a kind of quick change formula radiating tube to draw swollen assembly.
The utility model in order to solve the problems of the technologies described above taked technical scheme is:
Quick change formula radiating tube described in the utility model draws swollen assembly to comprise swollen head, T-shaped suspension member, connector, expander roll, T-shaped suspension member is two sections of all-in-one-piece versions processed, left end is cylindrical structural, right-hand member is truncated cone-shaped structure, on T-shaped suspension member, have axial hole, on T-shaped suspension member, also have radial slot, described radial slot is communicated with formation T character form structure with axial hole, described swollen head is connected with T-shaped suspension member left end by the first screw, described expander roll is connected with the right-hand member of T-shaped suspension member by the second screw, and between expander roll and T-shaped suspension member, connector is also installed, the head of screw of the second screw is placed in radial slot, the diameter of T-shaped suspension member and connector is less than the diameter of swollen head, the diameter of expander roll is less than the diameter of T-shaped suspension member and connector.
Preferred: described swollen head is the swollen head of carbide alloy.
Preferred: described connector is spindle structure.So arrange, connector is during as guiding parts, and spindle structure move freely expander roll in radiating tube, and the damage that elimination draws swollen assembly to cause radiating tube inner surface in drawing swollen process.
The utility model compared with prior art has following effect:
Quick change formula radiating tube of the present utility model draws the swollen head of swollen assembly easy to connect with expander roll, quick; The large footpath of swollen head is vertical with radiating tube axis all the time, guarantees crudy; Eliminated the damage of drawing swollen assembly to cause radiating tube inner surface in drawing swollen process.Quick change formula radiating tube of the present utility model draws swollen assembly to be mainly used on poling expand tube production line, has reached simultaneously and has changed rapidly, simple to operate, the effect of reliable operation.
Accompanying drawing explanation
Fig. 1 is the structural representation that quick change formula radiating tube draws swollen assembly;
Fig. 2 is the stereogram of T-shaped suspension member;
In figure: 1 is the first screw, 2 is swollen head, and 3 is T-shaped suspension member, and 4 is connector, and 5 is expander roll, and 6 is the second screw.
The specific embodiment
Elaborate with reference to the accompanying drawings the utility model preferred embodiment below.
The specific embodiment: the quick change formula radiating tube of present embodiment draws swollen assembly to comprise swollen 2, T-shaped suspension member 3, connector 4, expander roll 5, T-shaped suspension member 3 is two sections of all-in-one-piece versions processed, left end is cylindrical structural, right-hand member is truncated cone-shaped structure, on T-shaped suspension member 3, have axial hole, on T-shaped suspension member 3, also have radial slot, described radial slot is communicated with formation T character form structure with axial hole, described swollen 2 is connected with T-shaped suspension member 3 left ends by the first screw 1, described expander roll 5 is connected with the right-hand member of T-shaped suspension member 3 by the second screw 6, and between expander roll 5 and T-shaped suspension member 3, connector 4 is also installed, the head of screw of the second screw 6 is placed in radial slot, the diameter that the diameter of T-shaped suspension member 3 and connector 4 is less than swollen 2, the diameter of expander roll 5 is less than the diameter of T-shaped suspension member 3 and connector 4.
During swollen type, the external diameter of T-shaped suspension member 3 and connector 4 coordinates with radiating tube inwall is moving, makes the large footpath of swollen head vertical with radiating tube axis all the time, has guaranteed crudy.
Further: described swollen 2 is the swollen head of carbide alloy.
Further: described connector 4 is spindle structure.So arrange, connector is during as guiding parts, and spindle structure move freely expander roll in radiating tube, and the damage that elimination draws swollen assembly to cause radiating tube inner surface in drawing swollen process.
Present embodiment is the exemplary illustration to this patent just, does not limit its protection domain, and those skilled in the art can also change its part, as long as no the Spirit Essence that exceeds this patent, all in the protection domain of this patent.
