Description
Technical field
The present invention relates to plate in a kind of battery of mobile phone, in particular to sheet metal forming part and high-precision are fine and close in a kind of battery of mobile phone
Board fabrication method in property battery of mobile phone.
Background technique
In battery of mobile phone in the traditional forming method of plate, by pushing down the encapsulated positioning of molding on plate directly in battery of mobile phone
For hole, the bore dia of die cast be it is smaller than actual hole, mill off is then processed by CNC processing procedure, to guarantee aperture and position
The required precision of degree；This mode causes at high cost, and product competitiveness is low, and the tooth hole in battery of mobile phone on plate is not done at the time of molding
Out, it is directly completed by machining drilling, tapping, because of the setting in tooth hole and through-hole, formed product easily forms husky hole, drilling herein
Afterwards, cause a little husky hole of product lining to be exposed to outer, tooth to lock intensity inadequate.
Summary of the invention
In order to overcome drawbacks described above, the present invention provides board fabrication methods in a kind of battery of mobile phone, are added using this kind of scheme
Plate precision is high in the molding battery of mobile phone of work, and high-quality, processing cost is low.
The present invention is to solve technical solution used by its technical problem: board fabrication method in a kind of battery of mobile phone,
Specific step is as follows:
Step 1: sheet metal forming part in die cast battery of mobile phone, sheet metal forming part is located at plate in battery of mobile phone in battery of mobile phone
False tacking column is formed at the encapsulated location hole of side, and diameter is formed at the tooth hole of plate in battery of mobile phone less than tooth hole
The pre-formed hole of bottom outlet forms pre-formed hole of the diameter less than practical hole diameter in battery of mobile phone at the aperture of plate；
Step 2: being that positioning carries out blanking and punching with false tacking column；
Step 3: fine blanking hole, while washing out false tacking column and forming encapsulated location hole；
Step 4: bore expanded hole is carried out at pre-formed hole and forms aperture or bottom outlet；
Step 5: the bottom orifice tapping formed in step 4 forms tooth hole.
As a further improvement of the present invention, the false tacking column is the tapered pole that end diameter is less than root diameter (RD)
Body.
As a further improvement of the present invention, in the battery of mobile phone another side surface of plate also symmetrically set there are two draw glue
Groove and two winding displacement grooves, described two winding displacement grooves are located between two drawing glue grooves.
As a further improvement of the present invention, it is additionally provided at plate both sides of the edge in the battery of mobile phone several spaced
Dovetail groove and raised fastener.
As a further improvement of the present invention, in step 1 when preforming small hole forming using small insert structure carry out at
Type.
The beneficial effects of the present invention are: the present invention passes through the encapsulated location hole of plate in battery of mobile phone in die cast, it should
Position forms false tacking column, and when rear workshop section's blanking, punching can do positioning and use, when fine is related remove false tacking column,
It goes out encapsulated location hole to complete together, not only guarantees size, the position precision of encapsulated location hole in this way, also can guarantee punching workshop section
Same positioning required precision, this mode can reduce cost, improve product competitiveness, the tooth hole of plate and small in battery of mobile phone
Hole does small pin design in die cast and molds pre-formed hole, and pre-formed hole is made to be less than practical aperture and practical tooth bottom hole
Hole, then machining drilling, tapping are completed, and can effectively reduce the formation in the product tooth hole hole Chu Sha, improve product quality.
Detailed description of the invention
Fig. 1 is the first perspective view of plate in high-precision compactness battery of mobile phone；
Fig. 2 is the second perspective view of plate in high-precision compactness battery of mobile phone；
Fig. 3 is the first perspective view of sheet metal forming part in battery of mobile phone；
Fig. 4 is the second perspective view of sheet metal forming part in battery of mobile phone.
Specific embodiment
Embodiment: sheet metal forming part in a kind of battery of mobile phone is formed at the encapsulated location hole 7 of plate side in battery of mobile phone false
Tacking column 1.
The false tacking column 1 is the tapered cylinders that end diameter is less than root diameter (RD), and pyramidal structure is convenient for being cast into
Type.
Diameter is formed with less than 9 reality of 8 bottom outlet of tooth hole and aperture at the tooth hole 8 of plate and aperture 9 in the battery of mobile phone
The pre-formed hole 2 in aperture.
Another side surface of plate is also symmetrically set there are two drawing glue groove 3 and two winding displacement grooves 4 in the battery of mobile phone, described
Two winding displacement grooves 4 are located between two drawing glue grooves, and glue groove is drawn to be used for by drawing glue components, and winding displacement groove is used for cabling,
Surfacing, appearance looks elegant after assembling can be kept with after the assembling of other components.
Several spaced dovetail grooves 5 and raised fastener 6 are additionally provided in the battery of mobile phone at plate both sides of the edge, are led to
It crosses dovetail groove and raised fastener realization is fitted together with other components fast fastenings, it is easy to use, convenient for group installation and dismantling
It unloads.
Board fabrication method in a kind of battery of mobile phone, the specific steps are as follows:
Step 1: sheet metal forming part in die cast battery of mobile phone, sheet metal forming part is located at plate in battery of mobile phone in battery of mobile phone
False tacking column 1 is formed at the encapsulated location hole 7 of side, is formed with diameter at the tooth hole 8 of plate in battery of mobile phone and is less than
The pre-formed hole 2 of 8 bottom outlet of tooth hole forms diameter at the aperture 9 of plate in battery of mobile phone and is less than the preforming of practical 9 diameter of aperture
Hole 2；
Step 2: being that positioning carries out blanking and punching with false tacking column 1；
Step 3: fine blanking hole, while washing out false tacking column 1 and forming encapsulated location hole 7；
Step 4: bore expanded hole is carried out at pre-formed hole 2 and forms aperture 9 or bottom outlet；
Step 5: the bottom orifice tapping formed in step 4 forms tooth hole 8.
For the encapsulated location hole 7 of plate in die cast, which forms false tacking column 1, rear workshop section in battery of mobile phone
Positioning can be done when blanking, punching to use, when fine is related to remove false tacking column 1, goes out encapsulated location hole 7 completes together, this
Sample not only guarantees size, the position precision of encapsulated location hole 7, also can guarantee the required precision of the same positioning of punching workshop section, this
Kind mode can reduce cost, improve product competitiveness, the tooth hole 8 of plate and aperture 9 do small edge in die cast in battery of mobile phone
Needle design molds pre-formed hole 2, and pre-formed hole 2 is made to be less than practical aperture 9 and practical 8 bottom outlet of tooth hole, and then machining is bored
Hole, tapping are completed, and the formation in sand hole at product tooth hole 8 can be effectively reduced, and improve product quality.
It is formed when preforming aperture 9 forms in step 1 using small insert structure.
