Description
Technical field
The utility model is related to eliminate the oval aluminium alloy box shaping mould of strain.
Background technology
With the improvement of people's living standards, the requirement of the requirement, furniture for household, to its function, beautiful requirement
Also higher, home theater, home audio are also more and more common, and current sound chamber is to pursue beautiful, improving grade in shape, and one
As all use oval sound chamber, material to be generally aluminum alloy material.And in the casting process of aluminium section bar outline border, originally due to casting
Body can not can guarantee very high machining accuracy, generally between ± 0.7~± 1.5, and this speaker box, some visitors can be encountered
Family is very high to its requirement on machining accuracy, or even requires to reach ± 0.3, no matter how to cast all be unable to reach high in this way add in this way
Work precision is badly in need of a kind of solution.
Utility model content
The purpose of this utility model is that overcoming defect existing in the prior art, the oval aluminium for eliminating strain is provided
Alloy box shaping mould, energy shaping goes out high-precision oval aluminium alloy box, and makes dependent variable in advance on dressing stick, examines
The stress release for considering the oval aluminium alloy box of different situations, ensure that final shape and precision.
To achieve the above object, the technical solution of the utility model is a kind of oval aluminium alloy box for eliminating strain of design
Shaping mould, including lower die holder, the guide pad of fixed setting and the dressing stick that is slidably matched with guide pad, guide pad and shaping
Further include the slotting tool punching pin for dressing stick sliding after driving there are two block is all provided with, upper part is pyramidal, and dressing stick has
The shape on inclined-plane compatible with slotting tool punching pin top, its top surface of dressing stick is that a semicircle and an isosceles trapezoid are composed
Figure, the shape of the longitudinal section for being parallel to oval aluminium alloy box long axis of dressing stick is an inverted right-angled trapezium.More
For Preferable scheme is that two waists of isosceles system are not straight lines but curve；Pass through the drive of driving device such as cylinder or hydraulic cylinder
It is dynamic so that slotting tool punching pin moves upwards, since slotting tool punching pin and dressing stick coordinate, during moving upwards, dressing stick quilt
It pushes away and slides outward, play the role of to aluminium alloy box shaping；It is parallel and become cancave cambered surface to change two sides of previous dressing stick
Or convex globoidal, dependent variable is reserved on dressing stick in advance, the stress release of aluminium alloy box after demoulding is just offset in this way, ensures
Final product is indeformable after shaping.
Further technical solution is that the upper bottom or bottom of isosceles trapezoid are equal to half diameter of a circle.It is upper when isosceles trapezoid
When bottom is equal to half diameter of a circle, can be to avoid its stress release after-contraction of some aluminium alloy boxes the case where.When under isosceles trapezoid
When bottom is equal to half diameter of a circle, can be to avoid sticking out after some aluminium alloy boxes its stress releases the case where.
Further technical solution is that guide pad is fixed on lower die holder, is equipped in the middle part of lower die holder and is rushed for slotting tool
The through-hole that son moves up and down.
Another technical solution be further include the lower bolster being fixed on lower die holder, guide pad fixed setting
On lower bolster, the through-hole to move up and down for slotting tool punching pin is equipped in the middle part of lower bolster.Driving device can be arranged in this way
Slotting tool punching pin is driven to move up and down on lower die holder.
To ensure the controllable of shaping, preferred technical solution is that at least two pieces of lower cushion blocks are fixedly installed under lower die holder, is also wrapped
Include block of the detachable connection on lower die holder or lower bolster, the upper die holder with block detachable connection.The setting of block
It can prevent aluminium alloy box when shaping from expanding too much, upper die holder also suitably plays the role of blocking.
Further technical solution is that external stripping plate is additionally provided between block and lower die holder or lower bolster.External stripping plate also with gear
Block is detachably connected with, and such setting can easily be demoulded lower die holder, block and aluminium alloy box by external stripping plate, convenient for behaviour
Make.
The advantages of the utility model and advantageous effect are：It is exclusively used in the shaping of oval aluminium alloy box, and is fully examined
Consider the strain that will appear when different situations shaping, dependent variable is made in advance on dressing stick, by original two parallel side of dressing stick
Cancave cambered surface or convex globoidal are made, aluminium alloy box will not influence final shape having stress release after waiting shapings to complete demoulding
And precision.It is parallel and become cancave cambered surface or convex globoidal to change two sides of previous dressing stick, reserves answer on dressing stick in advance
Variable just offsets the stress release of aluminium alloy box after demoulding in this way, and final product is indeformable after guarantee shaping；Block is set
It sets aluminium alloy box when can prevent shaping to expand too much, upper die holder also suitably plays the role of blocking.
