Abstract
The utility model discloses a kind of gong plate that increases and folds several high length-diameter ratio gong knives, including handle of a knife and cutter head, and the cutter head is provided with blade, and the length of the cutter head and the diameter ratio of cutter head are（4.3~7.8）：1.The draw ratio of gong knife is optimized the utility model, and gong knife cutter head has a larger working depth under the draw ratio, thus be increased drilling when lamination quantity, improve drilling efficiency；At the same time, the gong knife of the draw ratio also has enough intensity, is not susceptible to stress fracture.
Description
Technical field
The utility model is related to printed wiring board production technical field, and in particular to a kind of height for increasing the folded number of gong plate is long
Footpath is than gong knife.
Background technology
Improved constantly with the economic level of China, electronic product emerges in an endless stream, and demand is also to improve year by year, more towards
In volume is light, slimming, for the amount of meeting the market requirement, while PCB manufacturing industry also brings very big challenge and opportunity, relative is auxiliary
The process technology of major ingredient is helped it is also proposed that acid test, it is necessary to try to lift itself market competitiveness.
Usually require to process all kinds of cavernous structures on printed wiring board, with the increase of cavernous structure quantity, drillman
Sequence turns into an important procedure of limitation wiring board production efficiency.Increase gong knife（Milling cutter）The length of cutter head can increase gong plate and fold
Plate quantity and thickness, but due to aperture fix and the diameter of gong knife can not be more than hole diameter, therefore increase cutter head length hold
Easily make cutter head stress and be broken.
Utility model content
In view of this, the gong knife for lamination quantity that the utility model is a kind of when can increase gong plate.
The purpose of this utility model is achieved through the following technical solutions：It is a kind of to increase the high length-diameter ratio gong that gong plate folds number
Knife, including handle of a knife and cutter head, the cutter head is provided with the length of cutter head described in blade and the diameter ratio of cutter head is（4.3~7.8）：
1。
In the utility model, the draw ratio to gong knife is optimized, and gong knife cutter head has larger add under the draw ratio
Work depth, therefore the quantity for the gong plate lamination that is increased, improve gong plate efficiency；At the same time, the gong knife of the draw ratio also has
Enough intensity, is not susceptible to stress fracture., can be in original using the utility model exemplified by the 0.8mm of aperture with thickness of slab 1.6mm
Increase by one block of lamination on the basis of technology, you can be while the wiring board processed to increase by one piece, hence it is evident that the wiring board of raising
Production efficiency.
Further, the length of the handle of a knife is 3.10-3.19mm.
Further, the length of the cutter head is 7.0-10.5mm.
Also the length of cutter head is optimized for the utility model, in the length range, and the utility model has last
Processing effect, cutter head is not susceptible to stress fracture.More than the scope, cutter head deadweight increase under the influence of gravity, easily becomes
Shape.By optimizing the length range of cutter head, the utility model can further increase intensity, gong cutter is had the longer use longevity
Life.
Further, it is additionally provided with transition region between the cutter head and handle of a knife；Its diameter of the transition region is along cutter head to handle of a knife
Direction gradually increases；The length of the transition region and the ratio of cutter head length are（0.3~0.5）：1.
In order to improve the intensity that gong knife is overall, the handle of a knife for installation typically has larger diameter, makes the installation of gong knife
Yielding, fracture is not allowed in position.In the utility model, the less cutter head of diameter and directly larger handle of a knife by a diameter gradually
The transition region connection of change, by increasing the length of transition region, transmits the strength between cutter head and handle of a knife and more relaxes,
It is even, it is to avoid junction deformation, the fracture of cutter head and handle of a knife.
Further, the enhancing groove of spiral surrounding is additionally provided with the transition region.
Enhancing groove can directionally strengthen the intensity of transition region, can offset the stress produced during gong plate, it is to avoid transition
Area's stress deformation.
The spaced cavities of multiple triangles are provided with the enhancing groove.
The spaced cavities of triangle have higher structural stability, on the one hand can further enhance the intensity of gong knife,
On the other hand it is also beneficial to mitigate the quality of gong knife.
The draw ratio of gong knife is optimized the utility model, and the cutter head of gong knife has larger processing under the draw ratio
Depth, therefore the quantity for the gong plate lamination that is increased, improve gong plate efficiency；At the same time, the gong knife of the draw ratio also has foot
Enough intensity, is not susceptible to stress fracture.Also the length of cutter head is optimized for the utility model, in the length range,
The utility model has last processing effect, and cutter head is not susceptible to stress fracture.More than the scope, cutter head deadweight increases,
Under the influence of gravity, it is easily deformed.By optimizing the length range of cutter head, the utility model can further increase intensity, make
Gong cutter has longer service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of the utility model transition region.
Embodiment
For the ease of it will be appreciated by those skilled in the art that making below in conjunction with accompanying drawing and embodiment to the utility model into one
