Abstract
The present invention is applied to daily life field, a kind of integrated punching formula drawing pin and processing method are provided, the drawing pin includes drawing pin cap, and the drawing pin cap is stamped and formed out downwards drawing pin pin, the punching hole consistent with the drawing pin aciculiform shape is left on drawing pin cap, the drawing pin pin is vertical with the drawing pin cap.In the present invention, drawing pin pin is obtained by the direct punching press of drawing pin cap, and without individually processing drawing pin pin, without welding drawing pin pin, drawing pin processing continuity of the present invention is good, and efficiency is very high；And because drawing pin pin and drawing pin cap are integrally formed, without welding step, therefore the possibility of drawing pin pin rosin joint are avoided, improve the quality of drawing pin.
Description
Technical field
The invention belongs to daily life field, more particularly to a kind of integrated punching formula drawing pin and processing method.
Background technology
Drawing pin on the market is usually straight drawing pin at present, very easy to use.Existing drawing pin includes drawing pin cap and setting
Drawing pin pin in drawing pin cap bottom center position, for object to be fixed on wall or notice such as newspaper, publicity report
On column.
In existing drawing pin processing technology, then drawing pin pin is directly welded at drawing pin by the manuscript head of a nail and drawing pin pin first
Cap bottom center, during this, the manuscript head of a nail and drawing pin pin are not synchronous, and continuity is not strong, individually processes drawing pin
The welding of artificial or equipment is also carried out after cap and drawing pin pin, process is comparatively laborious, influences production efficiency, also indirectly improves
Production cost.
The content of the invention
In view of the above problems, it is an object of the invention to provide a kind of integrated punching formula drawing pin and processing method, it is intended to solves
The technical problem of certainly existing drawing pin processing technology low production efficiency.
The present invention adopts the following technical scheme that：
On the one hand, the integrated punching formula drawing pin includes drawing pin cap, and the drawing pin cap is stamped and formed out downwards drawing pin pin, drawing pin
The punching hole consistent with the drawing pin aciculiform shape is left on cap, the drawing pin pin is vertical with the drawing pin cap.
Further, the drawing pin pin is arrowhead form or prong shape.
Further, the integrated punching formula drawing pin electroplating surface layer protecting film.
On the other hand, the integrated punching formula drawing pin processing method, comprises the steps：
The manuscript head of a nail；
Drawing pin cap is placed on workbench, using the direct punching press drawing pin cap of stamping machine, is formed down drawing pin pin, and drawing pin cap
On leave the punching hole consistent with the drawing pin aciculiform shape, the drawing pin pin is vertical with the drawing pin cap.
Further, the drawing pin pin is arrowhead form or prong shape.
Further, methods described also comprises the steps：
By integrated punching formula drawing pin electroplating surface layer protecting film.
The beneficial effects of the invention are as follows：In the present invention, the drawing pin pin of drawing pin is directly to be stamped and formed out, and drawing pin pin is for arrow
Shape or prong shape, the punching hole after punching press is also left on drawing pin cap；In this process, without individually processing drawing pin pin,
Without welding drawing pin pin, therefore drawing pin processing continuity is good, and efficiency is very high；In addition, drawing pin pin of the present invention is with drawing pin cap
It is integrally formed, without welding step, therefore the possibility of drawing pin pin rosin joint is avoided, improve the quality of drawing pin.
Brief description of the drawings
Fig. 1 is the front view of integrated punching formula drawing pin provided in an embodiment of the present invention；
Fig. 2 is the side view of integrated punching formula drawing pin provided in an embodiment of the present invention；
Fig. 3 is the top view of integrated punching formula drawing pin provided in an embodiment of the present invention；
Fig. 4 is the front view of another integrated punching formula drawing pin.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that the specific embodiments described herein are merely illustrative of the present invention, and
It is not used in the restriction present invention.
As Figure 1-3, the integrated punching formula drawing pin that the present embodiment provides includes drawing pin cap 1, and the drawing pin cap 1 is to undershoot
Swaging leaves the punching hole 3 consistent with the drawing pin aciculiform shape, the drawing pin pin 2 and the figure into drawing pin pin 2 on drawing pin cap 1
The head of a nail 1 is vertical.The present embodiment drawing pin is hard metal material, during manufacture, the manuscript head of a nail first；Then drawing pin cap is placed in work
Make on platform, using the direct punching press drawing pin cap of stamping machine, be formed down drawing pin pin, and left on drawing pin cap and the drawing pin aciculiform shape
Consistent punching hole, the drawing pin pin are vertical with the drawing pin cap.
In the present embodiment, drawing pin pin is that drawing pin cap punching press obtains, and drawing pin pin is vertical with drawing pin cap, and is integrally formed, Fig. 1
In shown, the drawing pin pin is arrowhead form, under actual conditions, as shown in figure 4, prong shape can also be stamped into.Processing
During, without individually processing drawing pin pin, without welding drawing pin pin, therefore drawing pin processing continuity is good, and efficiency is very high,
Reduce the production cost of drawing pin.
In addition, the drawing pin pin of existing drawing pin is welded to drawing pin cap bottom center, in actual use, often touch
To drawing pin crown portion breakage phenomenon, this be due to that drawing pin pin welding quality is bad or rosin joint caused by, and in the present embodiment, figure
It is integrally formed to follow closely pin and drawing pin cap, without welding step, therefore avoids drawing pin pin rosin joint possibility, improves drawing pin matter
Amount.
After punching press, punching hole is left on drawing pin cap, the usage amount of drawing pin metal is decreased, reduce further life
Produce cost.
In addition, in order to protect drawing pin not get rusty, extend the service life of drawing pin, the integrated punching formula drawing pin surface electricity
Plate layer protecting film.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement made within refreshing and principle etc., should be included in the scope of the protection.
