Abstract
The invention relates to a preparation process for a screw with a barb structure. The preparation process comprises the steps of S1, preparing a head part, a threaded rod and threads of the screw, S2, forming a plurality of barbs which extend from the bottom face down on the bottom face of the head part, and S3, removing rough edges. The preparation process for the screw with the barb structure is simple and easy to operate. According to the preparation process, the prepared screw with the barb structure is not prone to generate the phenomena of looseness and the like in a component connection process.
Description
Technical field
The present invention relates to a kind of preparation technology with screw of hangnail structure.
Background technology
Screw is to utilize the inclined-plane circular rotating of object and physics and the mathematical principle of frictional force, and the instrument of fastening implements parts, be a kind of conventional fasteners by easy stages.Its structure generally comprises head, the screw rod that extends to form of this head bottom surface and the screw thread that is formed at the screw rod outer rim certainly downwards, and in common screw element, screw enters into two connectors by revolving force, thereby connects two connectors.And after connecting two connectors, due to reasons such as vibrations, screw can be easy to the phenomenons such as generation reverses, becomes flexible usually.
Summary of the invention
The object of the present invention is to provide a kind ofly prevent to become flexible, the preparation technology of the screw with hangnail structure of the phenomenon such as disengaging.
For realizing aforementioned purpose, the present invention adopts following technical scheme: a kind of preparation technology with screw of hangnail structure is characterized in that: described preparation technology comprises the steps:
S1: head, screw rod and the screw thread of preparation screw;
S2: form in described head bottom surface several from the bottom surface hangnail towards downward-extension;
S3: burr removing.
As a further improvement on the present invention, also comprising the steps A1 between described step S2 and S3: offer several shrinkage pools on described hangnail.
As a further improvement on the present invention, also comprising the steps A2 between described step S2 and S3: form chip area on described screw rod and screw thread.
As a further improvement on the present invention, described hangnail tilts along the screw thread rotation direction.
This preparation technology is simple, and is easy to operate, and by the screw with hangnail structure that the present invention prepares, is difficult for producing the phenomenons such as loosening in the process of attaching parts.
Description of drawings
Fig. 1 has the structural representation of the screw of hangnail structure in the specific embodiment of the invention.
Fig. 2 is preparation technology's the process chart that has the screw of hangnail structure in the specific embodiment of the invention.
The specific embodiment
See also Fig. 2, a kind of preparation technology with screw of hangnail structure, this preparation technology comprises the steps:
S1: head, screw rod and the screw thread of preparation screw, because the preparation technology of this screw can adopt conventional process, therefore be not described in detail at this;
S2: form in described head bottom surface several from the bottom surface hangnail towards downward-extension, this hangnail is for to be obliquely installed along the screw thread rotation direction, can increase frictional force between screw and connector by this hangnail, and arrange along the screw thread rotation direction due to it, therefore can not make hangnail that damage is arranged when assembling;
S3: offer several shrinkage pools on described hangnail, can increase frictional force between hangnail and connector by offering shrinkage pool;
S4: form chip area on described screw rod and screw thread;
S5: burr removing.
Originally preparation method's (being step S1) can adopt conventional process due to the screw that uses in above-mentioned preparation technology, therefore, can obtain these parts by implement the method on plain screw at this, thereby can find out that its selection is convenient, technique is also fairly simple, and is easy to operate.
see also Fig. 1, for adopting the structural representation of the prepared screw of above-mentioned screw preparation technology with hangnail structure, described screw with hangnail structure comprises head 1, the screw rod 2 that extends to form downwards from head 1 bottom surface, and be formed at screw thread 3 on screw rod 2 outer rims, offer the chip area 5 for chip removal on this screw rod 2 and screw thread 3, certainly this chip area 5 also can only be opened on screw thread 3, its effect is identical with common chip area, namely can be with screw when connecting connector by this chip area 5, the bits that produce between screw and connector are last by this chip area 5 discharges, described head 1 bottom surface is formed with several hangnails 4, this hangnail 4 is around in screw rod 2 peripheries, hangnail 4 tilts along the screw thread rotation direction, when screw rotates into connector, because this hangnail 4 is to tilt along the screw thread rotation direction, hangnail 4 can enter in connector easily, it is the surface that hangnail 4 is imbedded connector, simultaneously also due to this kind design, itself can not produce destructiveness to hangnail 4 yet, and in order to increase the frictional force between hangnail 4 and connector, be provided with several shrinkage pools 41 on described hangnail 4, this shrinkage pool 41 can also be used for piling up the bits end that chip area 5 is discharged simultaneously.
Although be the example purpose, the preferred embodiment of the present invention is disclosed, but those of ordinary skill in the art will recognize, in the situation that do not break away from by the disclosed scope and spirit of the present invention of appending claims, various improvement, increase and replacement are possible.
