Description
Technical field
The utility model relates to cold-heading device fields, particularly a kind of for spending the molding cold-heading dress of tooth flange nut
It sets.
Background technique
A kind of colored tooth flange nut 1 is generallyd use in automobile instrument panel injection molding plates as attaching nut, structure such as Fig. 1 a-
Shown in 1b, flower tooth 11 and flange 12 are wrapped, the colored tooth 11 is equipped with an inner hole 13, sets between the colored tooth 11 and the flange 12
There is the threaded hole 14 of perforation, wherein the design length of the colored tooth 11 is only 2.95-4.1mm, the flange thickness of the flange 12
Only 2.8-3.17mm.
There are two types of the manufacturing method of existing colored tooth flange nut is usual, one is first use common cold-heading device forming embossing
Then the gear blank and flange of the flower tooth of tooth flange nut carry out annular knurl processing to gear blank using knurled wheel, secondly carry out to flange
Machine adds processing to obtain threaded hole bottom outlet, then carries out tapping to threaded hole bottom outlet, and finally materials and parts are heat-treated and are electroplated;It is another
Kind is first to add the gear blank for spending tooth out to the bar machine with flange diameter using machine add mode, is then carried out using knurled wheel to gear blank
Secondly annular knurl processing carries out machine to flange and processing is added to obtain threaded hole bottom outlet, then carries out tapping to threaded hole bottom outlet, finally to material
Part is heat-treated and is electroplated.When both methods has the disadvantage in that 1. use knurled wheel annular knurl tooth, due to needing to consider
The withdrawing space of knurled wheel, knurled wheel are difficult to roll out the part in gear blank with flanged joint into full colored tooth, this will affect colored tooth
Length, and then influence flower tooth flange nut bonding strength, if knurled wheel remove chamfering, as far as possible guarantee the full flower in root
Tooth, then the service life of knurled wheel will be greatly reduced;2. will cause waste of raw materials using machining mode, it is unfavorable for emission reduction consumption reduction;
3. annular knurl tooth and mach production efficiency are low, processing cost is high.
