Abstract
The invention discloses a kind of seamless bending mould of the air pressure for aluminium alloy plate, including punch, die plate insert, insert fixed seat, lower template, air chamber plug, compressed air inlet joint；Described insert fixed seat has primary airways, and described die plate insert has two grades of air flues, and described die plate insert fillet position offers a series of pores, and described pore is connected with air flue by air chamber.A kind of seamless bending mould of air pressure for aluminium alloy plate of the present invention, can effectively prevent article surface to be scratched and produce impression, the surface quality of product is substantially improved.
Description
Technical field
The present invention relates to bending mould technical field, particularly to a kind of seamless bending die of air pressure for aluminium alloy plate
Tool.
Background technology
In prior art, the typical structure of bending mould is made up of a upper mould and two lower moulds and lower template, such as schemes
Shown in 1.Bending die used by prior art be solid die, aluminium alloy plate with lower mould rounded contact be relative slip rub
Wipe, in forming process, plate is larger with mould fillet position touching position stress under bending；Prior art mold material is closed with aluminum
There is larger dissolving each other in golden plate material contact process, easily adhere between product and mould, and mold materials are harder, aluminum
Sheet alloy is softer, and therefore in forming process, the microgranule of aluminium alloy can be attached to die worker under bending and make on part surface.So,
Using prior art, aluminium alloy plate is curved, surface of the work can produce obvious cut and scratch.
Therefore, developing one kind prevents working surface to be scratched and produces impression, and products surface quality curved is substantially improved
Bent mould be die industry in the urgent need to.
Content of the invention
It is also easy to produce the problems such as obvious cut and impression for solving above-mentioned aluminum alloy plate materials in BENDING PROCESS, the present invention adopts
Following technical scheme：
The present invention provides a kind of seamless bending mould of air pressure for aluminium alloy plate, solid including punch, die plate insert, insert
Reservation, lower template, die plate insert are fixed in insert fixed seat, and insert fixed seat is fixed in lower template.Described insert is solid
Reservation has primary airways, and described die plate insert has two grades of air flues, and described die plate insert is set for fillet with punch corresponding position
Put, described die plate insert fillet position offers a series of pores, and described pore is connected with air chamber, air chamber and two grades of air flues
It is connected.
Advantages of the present invention and having the beneficial effects that：Provide compressed air gas circuit in a mold, when bending aluminium alloy plate
During material, compressed air sprays at a high speed at die entrance, and it is floating that the compressed air due to spraying forms upwards to aluminum alloy plate materials
Power, and form air film between aluminium alloy plate and insert, it is to avoid directly contact and generation at aluminium alloy plate and die entrance
Sliding friction, and the impurity particle that compressed air can will be attached on aluminum alloy plate materials blows away, thus preventing worksheet
Face is scratched and produces impression.The present invention provides compressed air gas circuit structure that the surface quality of product is substantially improved in a mold.
Brief description
Fig. 1 is the structural representation of the bending mould of prior art.
Fig. 2 is the structural representation of the bending mould of the present invention.
Fig. 3 is the structural representation of the bending mould of the present invention.
In figure, 1 is punch, and 2 is aluminium alloy bool, and 3 is die plate insert, 301 pores, and 302 is air chamber, and 303 are two grades
Air flue, 4 is insert fixed seat, and 401 is primary airways, and 5 is lower template, and 6 is air chamber plug, and 7 is compressed air inlet joint.
Specific embodiment
With reference to the accompanying drawings and examples, the specific embodiment of the present invention is described further.Following examples are only
For clearly technical scheme being described, and can not be limited the scope of the invention with this.
As shown in Figure 2 and Figure 3, the present invention provides a kind of seamless bending mould of air pressure for aluminium alloy plate,
Including punch 1, die plate insert 3, insert fixed seat 4, lower template 5, die plate insert 3 is fixed in insert fixed seat 4,
Insert fixed seat 4 is fixed in lower template 5.Described insert fixed seat 4 has primary airways 401, and described die plate insert 3 has two
Level air flue 303 and air chamber 302, described die plate insert 3 and punch 1 corresponding position are arranged for fillet, described die plate insert 3 fillet position
Offer a series of pores 301.
As priority scheme, described pore 301 is opened up along die plate insert 3 fillet radial direction and is connected with air chamber 302.
As priority scheme, also include compressed air inlet joint 7, described compressed air inlet joint 7 is arranged on one-level
Air flue 401 arrival end.
As priority scheme, also include air chamber plug 6, described air chamber 302 is blind hole, described air chamber plug 6 is arranged on gas
Room 302 arrival end.
When bending aluminum alloy plate materials, compressed air sprays at a high speed at die plate insert 3 fillet, and the compression due to spraying is empty
Gas forms buoyancy upwards to aluminium alloy bool 2, and forms air film between aluminium alloy bool and die plate insert 3, it is to avoid
The sliding friction of directly contact and generation at aluminium alloy bool 2 and the fillet of die plate insert 3, and compressed air is permissible
The impurity particle that will be attached in aluminium alloy bool 2 blows away, thus preventing working surface to be scratched and producing impression.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
For member, on the premise of without departing from art principle of the present invention, some improvements and modifications can also be made, these improvements and modifications
Should be regarded as protection scope of the present invention.
