Processing methods for furniture screw heads
TECHNICAL FIELD
The present invention relates to the field of screws used for assembling furniture, particularly to a method for processing the head of furniture screws.
Background technology
The traditional process for furniture screw heads is to first cut the iron wire into a standard length, and then use a cold heading machine to form the
head of the furniture screw through cold heading. Cold stamping is a method of cold stamping, which uses punching machines and various forming
molds to process it. The cold stamping forming molds are one male and one female.
The head of furniture screws produced by traditional cold heading technology is prone to serious cracks or eccentricity, resulting in a short service life
and complex process.
summary of the invention
The technical problem solved by the present invention is to provide a processing method for furniture screw heads that are not prone to cracking or
eccentricity and have a long service life.
In order to achieve the above objectives, the present invention provides a method for processing the head of a furniture screw. Firstly, the iron wire is cut
into multiple sections of screw blanks. Then, the screw blanks are pushed into the larger diameter end of the stepped groove at one end of the
stamping die through a machine ejector pin, and a forming strong beam stamping is performed to gradually press the screw blanks into the stepped
groove of the stamping die to form the head of the furniture screw. Finally, the other end of the stamping die uses a machine ejector pin to push out the
stamped screw blanks.
Furthermore, the stamping die includes two pieces that fit together vertically, and the two templates fit together to form a stepped groove.
Furthermore, the template comprises a mold base and a forming groove plate. The left end of the inner wall of the mold base has an installation groove,
and the forming groove plate is embedded in the installation groove.
Furthermore, the material of the formed groove plate is tungsten steel.
Furthermore, the stepped groove of the stamping die is a three-layer gradually inward stepped groove, which provides a radial rod between the head and
screw part of the processed furniture screws.
According to the technical solution of the present invention, the use of this mold for one-time stamping and forming of the head of furniture screws
makes it less prone to cracking or eccentricity, resulting in a long service life. In addition, the process of this processing method is simple.
