Description
Technical field
The present invention relates to a kind of rivet, particularly relate to the Technology for Heating Processing of a kind of BOM rivet collar.
Background technology
In traditional securing member, rivet and the collar are separated from each other, and the collar needs annealed, and the collar is overall by riveting gun
Extruding is shunk, and screw thread or annular groove with rivet are combined closely simultaneously；BOM nail rivet is knockdown with the collar, and this collar is at warp
After crossing original integrally annealed, riveting, set annular strain does not reaches design requirement.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the deficiencies in the prior art, it is provided that a kind of BOM rivet produced
Fastening effect is good, and collar two ends the most do not produce the Technology for Heating Processing of BOM rivet collar of plastic deformation.
For solving above-mentioned technical problem, the technical scheme that the present invention proposes is: the heat treatment work of a kind of BOM rivet collar
Skill, comprises the following steps, 1) collar carries out integrally annealed, and temperature is at 530 degrees Celsius, and the time is 3 hours；2) at distance collar tail
Carrying out local induction heating annealing at portion 5-15mm, induction apparatus is that red copper square tube is fabricated to annular, and height is 10mm, induction apparatus
With the gap between the collar is 1.45-1.55mm, carry out selecting superaudio 300 KHz as sensing during local induction heating annealing
Frequency, heat time heating time is the 2-3 second, and heating-up temperature is more than 720 degrees Celsius, and the power density needed for heating is 1.8-2.0KW/,
The collar rotates with the speed of 5r/s in heating process.In the present invention, select superaudio 300 KHz as induction frequencies, it is ensured that
Depth of penetration heating is higher than collar wall thickness 20%.
The conventional annealing temperature using heating by electric cooker selects 590-610 DEG C, and temperature retention time needs more than 1h；But employing office
Portion's sensing heating is the shortest due to heat time heating time, and the heating process time is the 2-3 second, and steel interior tissue fringe time is inadequate, by increasing
Add the degree of superheat, through test of many times, improve heating-up temperature to 720 DEG C, it is ensured that thermal effectiveness.
Power density needed for so-called heating refers to heat the performance number obtained on surface unit area.Ordinary circumstance
Under, when using high frequency or superaudio induction heating power, power density commonly uses 0.6-2.0KW/cm2, the power that we select
Density capping value 1.8-2.0 KW/cm2, it is ensured that firing rate meets requirement, reduces conduction of heat, it is ensured that the most right simultaneously
The extraneous region of BOM collar afterbody 5-15mm produces soft annealing.
The Technology for Heating Processing of above-mentioned BOM rivet collar, it is preferred that the thermal treatment zone upper of collar local induction heating annealing
Lower position is provided with a short-circuited conducting sleeve, also for the heat affecting reduced non-inductance heating district, the electromagnetism sense that surrounding dissipates
Should concentrate in short-circuited conducting sleeve, non-heated region not produced heat affecting.
Compared with prior art, it is an advantage of the current invention that: in the present invention, the part of distance collar afterbody 5-15mm is carried out
Local induction heating annealing i.e. sofening treatment, riveting process makes collar two ends the most not produce plastic deformation, and is overlapping away from BOM
Ring afterbody 5-15mm becomes cydariform, plays fastening effect.The BOM rivet that so present invention is produced can quickly and easily be pacified
Dress, installation effectiveness is high, can realize visual inspection, and the noise installed is little during installation, and after collar riveting, dimensional uniformity is good.
Detailed description of the invention
For the ease of understanding the present invention, below in conjunction with preferred embodiment, the present invention is made more comprehensively, describes meticulously,
But protection scope of the present invention is not limited to embodiment in detail below.
It should be strongly noted that when a certain element be described as " be fixed on, be fixed in, be connected to or be communicated in " another
Time on element, it can be directly the most fixing, affixed, connect or connect on another element, it is also possible to be by connecting in the middle of other
Fitting indirectly fixing, affixed, connect or connect on another element.
Unless otherwise defined, the implication that all technical term used hereinafter is generally understood that with those skilled in the art
Identical.Technical term used herein is intended merely to describe the purpose of specific embodiment, is not intended to limit the present invention
Protection domain.
Embodiment
The Technology for Heating Processing of a kind of BOM rivet collar, comprises the following steps, 1) collar carries out integrally annealed, and temperature is 530
