Description
【Technical field】
The present invention relates to the technical field of the production technology of pad, particularly a kind of commercial car special washer production technology
Technical field.
【Background technology】
Pad increases friction area, is prevented from nut loosening, the purposes of pad widely, according to purposes and environment
Difference, the material that pad is adopted and manufacturing process are also different, and the wheel of commercial car is solid by multiple big nuts and pad
Fixed, once there is news report to have a commercial truck, and one of wheel in journey was run on expressway and drops, this existing
The generation of elephant and the capability and performance of pad have close relationship, and because commercial car tire changing is more ordinary, loading capacity is big, so pad
Piece effect can decline, and the pad recycling frequency that prior art produces is few, and intensity is not well positioned to meet commercial car application
Demand, in order to improve the deficiency of material mechanical performance, need to improve the mechanical property of material using improving processing method, improve pad
The recycling rate of waterused of piece.
【Content of the invention】
The purpose of the present invention is exactly to solve the problems of the prior art, proposes a kind of commercial car special washer production technology,
The fixing reliability of commercial vehicle wheel can be improved, improve the production efficiency of pad, improve the intensity of pad, extend use
Life-span.
For achieving the above object, the present invention proposes a kind of commercial car special washer production technology, real by following steps
Existing：
A) medium carbon alloy steel is selected to be raw material, described raw material is 35CrMo, 42CrMo or B7；
B) spheroidizing is carried out to raw material；Described spheroidizing is that raw material is first to heat to 710 DEG C, is then incubated 1
～1.8 hours, then with the cooling of the speed of 36 DEG C/h～40 DEG C/h, be incubated 1～1.5 hour at 620 DEG C, then with less than 25 DEG C/h～
The speed of 35 DEG C/h is cooled to 570 DEG C；
C) by material cold-heading extrusion molding, make pad blank；
D) heat treatment is carried out to pad blank；Described heat treatment includes normalized treatment, temper and modifier treatment again；Institute
State normalized treatment, temperature is 800-1050 DEG C, the time is 6.1～7 hours, is then cooled to room temperature；Described temper, temperature
For 480-540 DEG C, the time is 6～7 hours, is then cooled to room temperature；Described modifier treatment again is to use under the conditions of 750-870 DEG C
Quenching oil carries out Quenching Treatment, carries out air cooling after 4～4.2 hours of oil cooling, is cooled to and is tempered when 310 DEG C, and 520 DEG C of temperature～
580 DEG C, 15～16 hours of tempering time, it is air cooled to room temperature；
E) pad blank is carried out, electroplating processes and packaging.
Preferably, by pad after oil removing, pickling pH value be 0.2～0.5 under conditions of room temperature blackening process 1～
2.5 hours.
Preferably, the hair blackening liquid that described room temperature blackening adopts when processing is made up of main film former and additive, described add
Plus agent is made up of the stabilizer that blacks, surface active agent, pH, speed regulator and secondary film formers.
Beneficial effects of the present invention：The present invention, by using the technique productions pad of cold-rolling treatment, can reduce pad life
Energy resource consumption during product, reduces production cost, improves production efficiency, improves the intensity of pad simultaneously, and the life-span is more
Long, safety is higher.
The feature of the present invention and advantage will be described in detail by embodiment.
【Specific embodiment】
A kind of present invention commercial car special washer production technology, is realized by following steps：It is raw material from rustless steel；
Spheroidizing is carried out to raw material；By material cold-heading extrusion molding, make pad blank；Heat treatment is carried out to pad blank；Right
Pad blank is carried out, electroplating processes and packaging.Described spheroidizing is that raw material is first to heat to 710 DEG C, is then incubated 1
～1.8 hours, then with the cooling of the speed of 36 DEG C/h～40 DEG C/h, be incubated 1～1.5 hour at 620 DEG C, then with less than 25 DEG C/h～
The speed of 35 DEG C/h is cooled to 570 DEG C；Described heat treatment includes normalized treatment, temper and modifier treatment again.Described normalizing
Process, temperature is 800-1050 DEG C, the time is 6.1～7 hours, is then cooled to room temperature.Described temper, temperature is 480-
540 DEG C, the time is 6～7 hours, is then cooled to room temperature.Described modifier treatment again is to use quenching oil under the conditions of 750-870 DEG C
Carry out Quenching Treatment, after 4～4.2 hours of oil cooling, carry out air cooling, be cooled to and be tempered when 310 DEG C, 520 DEG C～580 DEG C of temperature,
15～16 hours of tempering time, are air cooled to room temperature.By pad after oil removing, pickling pH value be 0.2～0.5 under conditions of
Room temperature blackening processes 1～2.5 hour.The hair blackening liquid that described room temperature blackening adopts when processing is by main film former and additive group
Become, described additive is made up of the stabilizer that blacks, surface active agent, pH, speed regulator and secondary film formers.Institute
