Abstract
The utility model provides a tubular product throat machine, including the lathe, install the rotating head on the lathe, has seted up die hole along the axial in the rotating head, the mould is formed along the concatenation of circumference order by at least 2 cylinders, and it be triangle -shaped that the cross section of the concatenation section of cylinder be convex, longitudinal section, follows an axiform one -tenth bell mouth in the mould after the concatenation. The utility model discloses a mould is dismantled and assembled, is convenient for rinse the mould.
Description
Technical field
This utility model belongs to tubular object extruding field, is specially tubing reducing equipment。
Background technology
Metal tube is widely used in the fields such as artware as skeleton。When metal tube being carried out reducing operation, generally it is processed on necking machine。
Existing necking machine includes lathe, and lathe is provided with swivel head, offers the die hole embedded for necking die 4 ' fastening vertically, offer the bellmouth 7 ' (as shown in Figure 1) inserted for tubing in necking die 4 ' vertically in swivel head。In work process, necking die 4 ' is inserted in die hole according to bellmouth 7 ' tip court。Workman holds tubing, and tubing needs one end of reducing stretch into the big opening of bellmouth 7 ' of necking die 4 ' swivel head from through hole。Starting necking machine, necking die 4 ' will rotate with swivel head。Along with workman promotes tubing to mobile in bellmouth 7 ', the end of tubing will according to the size reduction of the bellmouth 7 ' of mould 4 '。
But, owing to existing necking die is a unitary member axially inside offering bellmouth, when bellmouth is deeper, it is unfavorable for the bottom of bellmouth is cleared up。Further, use for a long time, often occur between necking die and swivel head skidding affecting reducing effect。
Summary of the invention
This utility model aims to provide a kind of Pipe necking machine easy to clean。
A kind of Pipe necking machine, including lathe, lathe is provided with swivel head, die hole is offered vertically in swivel head, mould is formed by least 2 cylinders circumferentially sequential concatenation, the cross section of the splice sections of cylinder is circular arc, longitudinal cross-section is triangle, forms a bellmouth along axle in spliced mould。
Mould described in the utility model is formed by least 2 cylinders circumferentially sequential concatenation, can mould be split, and conveniently the foreign material in the bellmouth of mould is cleared up。
Described mould is preferably between adjacent columns face contact, the frictional force between cylinder can be increased, be beneficial to the stability in the large maintaining mould, it is possible to avoid cylinder to be subject to local stress and damaged。
The swivel head of the port of described die hole also detachably arranges cover plate, cover plate offers the through hole corresponding with the bellmouth of mould, when can avoid, between mould and swivel head, skidding occurs, mould separating swivel head。In specific implementation process, the Detachable connection structure between swivel head with cover plate is: cover plate is connected with swivel head by screw。It addition, cover plate is connected with mould also by screw, can avoid mould that skidding occurs。

Detailed description of the invention
Now it is specifically described embodiment of the present utility model:
In conjunction with Fig. 2, Fig. 4, a kind of Pipe necking machine, including lathe 1, lathe 1 is provided with swivel head 2, die hole 3 is offered vertically in swivel head 2, mould 4 is formed by least 2 cylinders 5 circumferentially sequential concatenation, and the cross section of the splice sections of cylinder 5 is circular arc, longitudinal cross-section is triangle, forms a bellmouth 7 along axle in spliced mould 4。
Mould 4 described in the utility model is formed by least 2 cylinders 5 circumferentially sequential concatenation, can mould 4 be split, and conveniently the foreign material in the bellmouth 7 of mould 4 is cleared up。
As in figure 2 it is shown, described mould 4 is preferably between adjacent columns 5 face contact, the frictional force between cylinder 5 can be increased, be beneficial to the stability in the large maintaining mould 4, it is possible to avoid cylinder 5 to be subject to local stress and damaged。
As shown in Figure 3, Figure 4, the swivel head 2 of the port of described die hole 3 also detachably arranges cover plate 9, offering the through hole 10 corresponding with the bellmouth 7 of mould 4 on cover plate 9, when can avoid skidding occur between mould 4 and swivel head 2, mould 4 departs from swivel head 2。In specific implementation process, the Detachable connection structure between swivel head 2 with cover plate 9 is: cover plate 9 is connected (as shown in Figure 3,4) with swivel head 2 by screw 11。It addition, cover plate 9 is connected (as shown in Figure 3,4) with mould 4 also by screw 11, can avoid mould 4 that skidding occurs。
Certainly, the shape of mould of the present utility model, the shape of cylinder, cylinder quantity be not limited to the concrete structure in accompanying drawing。
