Description
Technical field
The present invention relates to a kind of punching die of keyboard of notebook computer framework.
Background technology
The keyboard frame of quite a few notebook computer is stamped and formed out by metal shell at present.Due to keyboard
Keyhole is more on framework, densely distributed, and when disposable punching is molded, impulsive force great Yi causes keyhole to deform
Collapse, and due between keyhole connecting portion it is narrower, connecting portion both sides synchronous punching in punch process,
It is easily caused connecting portion fracture.Keyboard of notebook computer frame mold structure is complicated at present, and product quality needs to be carried
It is high.
The content of the invention
The problem to be solved in the present invention is：A kind of punching die of keyboard of notebook computer framework is provided.
To solve the above problems, technical scheme provided by the invention is：A kind of keyboard of notebook computer framework
Punching die, for the punching keyhole on keyboard frame, including upper die and lower die, the upper mould includes
Upper bolster, upper mould fixed plate, piercing punch and the stripper being sequentially connected from top to bottom, the lower mould bag
Include the die shoe being sequentially connected from bottom to top, lower mold fixed plate and combined die, in the technical program, institute
Stating piercing punch includes the first drift area and the second drift area, and the first drift area is provided with multiple for rushing
The drift of non-conterminous part keyhole is made, the second drift area is provided with the drift of punching surplus keyhole, institute
State combined die and be provided with the first cavity plate being engaged with the first drift area, with the second drift area phase
The second cavity plate coordinated.The mould carries out two keyboard frame stamping parts synchronization punching, the first drift simultaneously
Area coordinates with the first cavity plate goes out a part of non-conterminous keyhole, the second drift on first keyboard frame
Area coordinates with the second cavity plate goes out corresponding on first keyboard frame lack mutually on second keyboard frame
The keyhole of benefit, complete first time punching press, then the first keyboard frame with the second keyboard frame transposition,
The punching press of remaining keyhole is completed on each comfortable two keyboard frame.The punching die structure is simple, punch process
It is divided into two steps, keyhole Monodispersed arrangement is rushed in often walking, reduces impulsive force suffered by framework, is reduced
Framework and keyhole deformation, and side stress in each punching step of keyhole connecting portion, it is disconnected to reduce it
Split；The first drift area and the second drift area are concentrated on same piercing punch simultaneously, once carry out two
Keyboard frame synchronous punching, efficiency high.
Further, the stripper is provided with rushes with what the first drift area and the second drift area arranged
Corresponding through hole, the drift are extend out on the downside of the stripper through the through hole.
Further, the stripper is slidably connected with the upper bolster through bolt, and bindiny mechanism is simply easy
In realization.
Further, the keyboard frame is preset with some positioning holes, the first cavity plate of the combined die
With the alignment pin that is engaged with the positioning hole is equipped with the second cavity plate.The setting of alignment pin facilitates keyboard
Framework stamping parts positions after exchanging position, improves keyhole positional precision.
It is an advantage of the invention that：
1. the punching die structure is simple, keyhole punching process is divided into two steps, is rushed in each step
Keyhole Monodispersed is arranged, reduces impulsive force suffered by keyboard frame stamping parts, reduces framework and keyhole
Deformation；A side stress in each punching step of keyhole connecting portion, so as to reduce its fracture；While the
One drift area and the second drift area are concentrated on same piercing punch, and it is same once to carry out two keyboard frames
Walk punching, efficiency high.
2. stripper is simple in construction, connected mode is easily achieved, and the setting of alignment pin facilitates framework stamping parts
Positioned after exchanging position, improve the positional precision of punching keyhole
