Description
Technical field
The utility model relates to thin-wall pipe processing technique field, especially a kind of forging work that thin-wall tube both ends are upset
Dress.
Background technique
With the development of market economy, every industrial products gradually to more efficientization, it is lighter words and it is more humane
Direction is developed.Wherein, rock drilling Down-the-hole rod is no exception.User often may require that manufacturer after meeting basic functionality demand
Mitigate the weight of drilling rod as far as possible to reduce operative employee and equipment workload, therefore, thin-wall tube is widely used in the field.Work
Commonly using drilling rod specification in journey construction has φ 76, φ 89, φ 102, φ 114 etc..Thickness 4.5mm thick and thin wall is selected by taking 76 drilling rod of φ as an example
The upset latter made long 3m drilling rod weight in pipe both ends is 27.8kg, and thick 6.5 pipe weight reduce 8.6kg before opposite, the product
The deep favor by client.
Fig. 1 is common 76 jackrod structure figure of φ；1. being fillet of tool joint pins, 2. the body of rod for both ends after upset, is 3. drilling rod
4. 5. female connector is interior overlap after drill pipe friction；Fig. 2 is thin-wall tube one end shape after upset；Fillet of tool joint pins 1.,
3. 2. tool joint box is connected as one with the body of rod by way of friction welding (FW) respectively, see Fig. 3, Fig. 4.
The process equipment and method of the existing upset body of rod in both ends are as follows:
Such as Fig. 5,6, component 1 is more valve modular fixture (see figure 6)s, and effect is clamping thin-wall tube 2 and control tube body
Upset outer diameter (being similarly shaped cavity plate effect), the driving of the first hydraulic-driven module 51 will be so that the completion of more valve modular fixtures 1 will
2 pinching action of thin-wall tube；Component 4 is locking nut, and effect is that forming terrace die 3 is fixed in hydraulic-driven module 5.
Specific process step: one, thin-wall tube is placed in more valve modular fixtures 1 after upset end is heated to set temperature,
And thin-wall tube waits for that upset end face must not stretch out fixture end face B；Two, hydraulic-driven module is opened to clamp thin-wall tube 2；Three, start
Second hydraulic-driven module 5 makes forming terrace die 3 mobile toward tube body；When to Fig. 7, completes after poly- material forming and punch-pin 3 is right
It moves, more valve modular fixtures 1 loosen.
The upset method has drawback:
1, more valve modular fixtures 1 are tube body clamping members；It is also die body, i.e. its inner cavity directly connects with high temperature tube body
Touching, at high operating temperatures, mechanical mechanics property will be greatly reduced entire upset process, multiple high temp and by contradicting tube body deformation
Power, cause its oral area easily to deform, thus, influence upset quality.
2, it works under the operating condition of high-temp and high-strength, is vulnerable part, and makes complicated, at high cost.
3, more valve modular fixtures 1 are more valve combined types, are equipped with certain interval t between every valve and step up effect to reach, by
In rolling out OD of Thin Wall Welded Pipe size in a value range, there are every batch of pipe diameters the case where big difference.So depositing
Clearance t is too small between the every valve of fixture block will lead to not clamping, when clearance t is excessive, gather material during upset in clearance t in tube body
Surface forms small rib, and upset shape cannot reach design requirement.
4, the poly- material step 31 on punch-pin 3 at work can be with the poly- material forming of more 1 inner holes of valve modular fixture, cooperation
The size in gap and the error of the two axis will have a direct impact on upset quality, so component production is complicated, assembly precision is wanted
Ask high.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of forging tooling that thin-wall tube both ends are upset, this forgings
Tooling can be effectively solved presently, there are the problem of, and then guarantee thin-wall tube both ends jumping-up quality.
In order to realize above-mentioned technical characteristic, purpose of the utility model is realized as follows: a kind of thin-wall tube both ends pier
Thick forging tooling, it includes more valve modular fixtures, and more valve modular fixtures and the first hydraulic-driven module match,
And thin-wall tube is clamped；It is characterized by: being provided with the positioning step with cavity plate cooperation on punch-pin, the cavity plate and die shank match
Punch-pin is fixed on die shank by conjunction；The die shank is fixedly mounted in the second hydraulic-driven module by locking nut.
It is provided with draft angle β on the punch-pin, the inner wall of the cavity plate is provided with draft angle β, the punch-pin and recessed
Mould matches to form die cavity.
By being threadedly engaged connection between the cavity plate and die shank.
The depth L2 of the cavity plate is less than the length L1 that thin-wall tube needs heating part.
The utility model provides the shortcomings that a kind of double intracavity outer tube impactors effectively overcome existing impactor, in structure
On carried out major transformation, in contrast have the advantage that
1, since more valve modular fixtures do not contact high temperature tube body, general steel production is only made clamping component, is greatly improved
Its service life；Original process scheme fixture is made clamping component and need to be made of heat resisting steel for cavity plate, production complexity, cost
It is high.
2, clearance t size will not influence upset forming quality between more valve modular fixture upper fixture blocks, and fixture can use big model
Enclose the caliber of diameter deviation.
3, Die Design is rationally monoblock type, opposite multi-clove type reasonable stress before, and short with the high temperature contact time, about
Originally 1/4, service life greatly improves.
4, punch-pin and die shank are designed as split type component, and punch-pin is heat resisting steel production, and die shank is general steel production, save
Cost of manufacture, upset tube body specification is not required to integral demounting die shank when generating variation, easy to operate.
