Abstract
The utility model discloses a kind of bellowss to shape adjustable spacing block, it is related to metal bellows molding equipment technical field, including ontology one and ontology two, ontology one is cylindrical body, ontology two includes integrally formed adjustment portion and operation portion, operating position is above adjustment portion and adjustment portion is cylindrical body, and ontology one and adjustment portion are connected through a screw thread and are adjusted by the thread the whole height of ontology one Yu ontology two；The utility model uses screw type spacing block, and whole height can adjust as needed, when making different bellowss, as long as by required size is highly adjusted to, without making new spacing block；Cost is effectively reduced, service efficiency is improved.
Description
Technical field
The utility model relates to metal bellows molding equipment technical fields, shape more particularly to a kind of bellows adjustable
Spacing block.
Background technique
The corrugation of bellows is the critical process for manufacturing bellows, and common manufacturing process has: hydroforming, welding
Forming, mechanical molding, rubber molding etc..Wherein, hydroforming is the common technique of metal bellows manufacturing, forming side
Method is suitable for manufacture the stainless steel with good plasticity, the S types of the materials such as copper alloy, elastic alloy and high temperature, Ω type, U-shaped etc.
The bellows of waveform has good craftsmanship and extensive adaptability.
Ripple tube hydroformation is pipe in the case where being acted on by inner wall fluid pressure, when the surrender that stress is more than blank tube material is strong
It is ripple in matrix internal shaping after degree.The process of ripple tube hydroformation is as shown below, and pipe is fitted into mold, then
It is packed into matrix and spacing block, as shown in Figure 1；Pipe is set to play bulge by hydraulic inside pipe, fixed matrix, removal spacing block is as schemed
Shown in 2；Forming machine piston rod pushes matrix to move down, and pipe becomes wave under forming pressure effect, as shown in figure 3, last release,
Forming finishes.Spacing block in ripple tube hydroformation equipment (is namely controlled for controlling the locating piece of bellows wave height
The size of bulging bulge), the spacing block of common vertical form machine be with steel pipe Vehicle Processing, height dimension H be it is fixed, such as
Shown in Fig. 4.The spacing block of every kind of fixed specification can only make a kind of bellows of wave height, if adjusting wave height, need
The spacing block of new spec is made, to meet the wave height of different requirements.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of bellows forming adjustable spacing block, including ontology
One and ontology two, ontology one is cylindrical body, and ontology two includes integrally formed adjustment portion and operation portion, and operating position is in adjustment portion
Top and adjustment portion are cylindrical body, and ontology one and adjustment portion are connected through a screw thread and are adjusted by the thread ontology one and ontology two
Whole height.
Technical effect: the utility model uses screw type spacing block, and whole height can adjust as needed, and production is not
When with bellows, as long as by required size is highly adjusted to, without making new spacing block.
The technical solution that the utility model further limits is:
A kind of preceding bellows shapes adjustable spacing block, and ontology one is equipped with internal screw thread, and adjustment portion is equipped with outer spiral shell
Line.
A kind of preceding bellows shapes adjustable spacing block, and operation portion is the outer diameter circle equal with one outer diameter of ontology
Cylinder, and flat nick is symmetrically arranged on the operation portion.
The beneficial effects of the utility model are:
(1) the utility model is simple using the spiral gauge block structure of spiral way design, easy to make；
(2) the spiral spacing block whole height of the utility model design is adjustable, reduces costs, and improves using effect
Rate.
Detailed description of the invention
Fig. 1-Fig. 4 is background technique schematic diagram；
Fig. 5 is the structural schematic diagram of the utility model；
Wherein: 1, ontology one；2, ontology two；2a, adjustment portion；2b, operation portion.
Specific embodiment
A kind of bellows provided in this embodiment shapes adjustable spacing block, and structure is as shown in figure 5, include ontology 1 and this
Body 22, ontology 1 are cylindrical body, and ontology 22 includes integrally formed adjustment portion 2a and operation portion 2b, and operation portion 2b, which is located at, to be adjusted
Above section portion 2a and adjustment portion 2a is cylindrical body, and ontology 1 and adjustment portion 2a are connected through a screw thread and are adjusted by the thread ontology
1 with the whole height of ontology 22.Ontology 1 is equipped with internal screw thread, and adjustment portion 2a is equipped with external screw thread.Operation portion 2b is outer
The diameter cylindrical body equal with one 1 outer diameter of ontology, and flat nick is symmetrically arranged on the operation portion 2b.
The utility model uses screw type spacing block, and whole height can according to need adjustment, make different bellowss
When, as long as by required size is highly adjusted to, without making new spacing block；Structure is simple, easy to make；It reduces costs,
Improve service efficiency.
In addition to the implementation, the utility model can also have other embodiments；It is all to use equivalent replacement or equivalent change
The technical solution to be formed is changed, the protection scope of the requires of the utility model is all fallen within.
