Technique processed belongs to industrial fastener manufacture field.
Background technique
Currently, internal clamp riveting nut processing enterprise, state is in stainless steel riveting nut process, to STAINLESS STEEL WIRE phase
It is indefinite to close parameter (each station material hardness of such as mechanical property, chemical content, mold) requirement, makes it in subsequent pier process
Middle product can generate cracking phenomena；And stainless steel riveting nut generally all pier at normal temperature, it is not also heat-treated after pier system
To the not clear standard of the requirement on temperature and time having heat treatment, therefore it is unstable to will cause technique, processes waste product
More, qualification rate is low, and riveting effect is low so as to cause stainless steel riveting nut production efficiency, it is difficult to shape often up to less than prescribed requirement
It is produced in batch to meet the market demand.Cut-off till now, both at home and abroad not yet occur to stainless steel riveting nut production technology with
The related data or report of the requirement of technology etc., also without standard queries.
Summary of the invention
For deficiency existing for the above-mentioned riveting nut production technology of stainless steel in the prior art, the present invention provides one kind and can guarantee
Stainless steel riveting nut stable processing technique, qualification rate is high, and riveting effect meets prescribed requirement, and is suitable for the stainless of batch production
The pier technique of steel riveting nut.
The technical scheme is that: a kind of upsetting technique of stainless steel riveting nut, main through the following steps that realizing:
(1) preparation of raw material: the selection trade mark is 302HQ STAINLESS STEEL WIRE, it is desirable that material makees brilliant spheroidizing, guarantees
Tensile strength is about in 55MPa or so in the mechanical performance index of material, make its during subsequent pier product without cracking
Phenomenon occurs；
(2) preparation of mold: being designed using six station dies, and one, two, four, five, six station punch materials use import
M42 material, heat treatment hardness HRC65-67, three station punch materials use import ASP30 material, heat treatment hardness HRC67-
68.5, all formed punches make titanizing processing resistant to high temperatures；Undershoot material is using SKH -55 material of Japanese import, and heat treatment is firmly
Spend HRC64-66；Carbide matrix material uses TaiWan, China import VA90 material；
(3) preparation of equipment: TaiWan, China import equipment 19B type multistage cold former is used, six station dies are passed through
Mold installation attachment is mounted on multistage cold former, and installs stainless steel additional on multistage cold former by material supporting device
Material heater is realized and is controlled the temperature of pier wire rod；
(4) raw material: being passed through heater first and heated to wire rod by upsetting semi-finished product, and the temperature of wire rod is controlled in 200-
It 400 DEG C, to guarantee to stretch macropore in three stations, then puts in a mold using cylindrical cutter progress upsetting system, during upsetting system, should divide
There is not oil pipe to formed punch and cavity plate lubricating oil spraying, when necessary, also needs to be safeguarded using die repairing device；
(5) de-oiling, hot wash and drying: by using special de-oiling, hot wash and drying equipment and balance crane, upsetting is made
Semi-finished product de-oiling, hot wash and drying guarantee that subsequent handling is normally implemented；
(6) solution treatment, solid solubility temperature control solution treatment: are implemented to upsetting semi-finished product using dedicated Solution Treatment Furnace
At 1050 DEG C, solution time keeps 30min to guarantee that the quality of product meets the requirements of the customers to eliminate its internal stress, it is ensured that
Product press deformation after without infolding, warping phenomenon occur；
(7) tapping: by using improved automatic tapping machine and special screw tap, product screw thread is enable to guarantee by GB/T
3934-2003 can be passed through through the go side of the qualified go-no go gauge of verification and not-go-end is no more than 2 buttons half；
(8) polish: the product complete to tapping polishes；
(9) pack: packaging product is with to be vended.
Advantages of the present invention: by being wanted to material, mold and the processing method regulation in stainless steel riveting nut production technology
It asks, can guarantee stainless steel riveting nut stable processing technique, qualification rate is high, and riveting effect meets prescribed requirement, and can manufacture,
Improve production efficiency.
Specific embodiment
