Fig. 2 is the broken view structural schematic diagram of the utility model.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solution novel to this reality is described in further detail.
Embodiment 1: as depicted in figs. 1 and 2, a kind of tractor carbon fiber Wet-type paper friction plate, including antithesis piece 1, institute
Material used in the core plate for the pairing steel sheet 1 stated with it is copper-based identical, kind is also roughly the same, less than 4mm can punch forming,
Greater than 4mm gas cutting can be used, line is cut, laser is cut etc., and modes are processed.But requirement of the paper-base friction wafer to core plate geometric tolerance is high
In copper base, especially surface roughness, the depth of parallelism, flatness, if not reaching requirement, subsequent patch can be influenced.Patch
Process be the core plate of first-class glue and the scraps of paper that are cured are arranged on vulcanizing press with certain temperature, time come it is completing,
The semi-finished product for posting piece are exactly the blank of paper-base friction wafer, and tractor carbon fiber Wet-type paper has just been made by following process and has rubbed
Pad.The bonding intensity of patch is inadequate, directly influences the use of friction plate, and therefore, core plate will be reached by grinding process
It arrives.Have particular/special requirement will also make core plate have certain intensity and hardness into heat treatment.The interposition of the pairing steel sheet 1
Equipped with pilot hole 2, the edge of the pilot hole 2 is equipped with assembly tooth 3, and the number of teeth of the assembly tooth 3 is 32, pair
The front and back of even steel disc 1 is respectively equipped with the paper substrate 4 to fit therewith, and the bonding intensity of patch is inadequate, directly influences
The use of friction plate, therefore, core plate will reach by grinding process.Have particular/special requirement will also make core plate into heat treatment
There are certain intensity and hardness.The core plate of paper substrate is very high to the clean-up performance requirement on surface, and core plate surface cannot have greasy dirt, ash
Dirt and any objectionable presence.Except in addition to hot water, cold water wash, it is also necessary to it is cleaned with acetone, it could gluing processing after drying.
The surface of the paper substrate is equipped with the arc groove by 7 phase composition of up time slot 6 and inverse time slot, the arc groove and assembly tooth 3
Between be equipped with oil-through hole 5, the quantity of the oil-through hole 5 is 6, and the oil-through hole 5 is annular in shape.The up time slot 6 and inverse
The arc radius of time slot 7 be 105mm with centering on the basic circle of diameter 180mm in arc-shaped distribution, the up time slot 6 and inverse
Arc groove two-way each 40 of the groove width 1mm of time slot 7, outside 30 ° of chamferings, up time slot 6 and inverse time slot 7 are uniformly distributed.
High temperature friction regulator filler is used in this product process, reduces material thermal wear.Steel plate is taken, first using punching
Bed rushes inside and outside circle, then with Internal hole positioning, rushes 6 uniformly distributed diameters on the steel plate and is the hole of 30mm, then be heat-treated, is hardened
HRC is 46~50, and then the two sides of core grinding plate, is cleaned on cleaning machine, removes surface and oil contaminant, is dried, then with third
Ketone cleans core plate two sides, cleans up steel back surface micropore dust and remaining grease stain, improves adhesion strength, shear strength.
Using the formula of optimization: cotton pulp 31%, carbon fiber 15%, graphite 30%, diatomite 10%, feldspar powder 10%, Frication powder 9%, latex 3%.
It is processed using diamond-impregnated blade, solves soft material and asked in the overlap at the finished surface edge that machining generates and burr etc.
Topic, surface roughness is improved well, to improve the presentation quality of product.Surface treatment uses homemade specific brush
Ray machine replaces to be cleaned with water by hand, and efficiency improves 4-5 times.
Different according to material prescription carry out ingredient, are beaten in a manner of papermaking after the completion, different from common papermaking
Be the various minerals for being added to different role, in order to make addition various minerals mashing when do not generate component segregation,
It also added a certain amount of latex rubber in material to play the role of setting off filler.After the completion of mashing can copy paper, copy paper
Thickness will be determined according to the requirement of product.It to be dried after copy paper is good, sunlight can be used to dry for drying process,
It can dry in different ways.What the glue of scraps of paper leaching was usually carried out with the phenolic resin glue of modified form: this resin glue is commonly called as
" cashew nut shell oil ".Virgin rubber need to be diluted with absolute alcohol, and diluted concentration is about 60% containing glue, certainly specifically will be according to friction plate
Density determines that the scraps of paper after impregnation need drying, drying mode is can to dry with sunlight, and different modes drying can be used.Punching
The scraps of paper after sanction are solidified.Cured purpose be in order in the scraps of paper adhesive curing, be equivalent to the process of setting of concrete.
Equipment used in solidifying is baking oven, and the temperature of setting is not above 160 DEG C.Curing time will be depending on the thickness of the scraps of paper.
The foregoing is merely the structure features of specific embodiment of the utility model, but the utility model to be not limited to
This, in the field of the utility model, made changes or modifications all cover practical new at this any those skilled in the art
Among the scope of the patents of type.
