According to a further aspect in the invention, the molding of a kind of belt and cutting method, employ a kind of mould, wherein, the quantity of described mould 2 is multiple, each described mould 2 is cylinder, its outer circumference surface is provided with axially extended mould teeth groove 22, for forming the band tooth 94 on described Timing Belt, centre is axially extending bore 24, wall thickness between described axially extending bore 24 and the outer circumference surface of each described mould 2 is additionally provided with axially extended fastening through-hole 23 and Blind locating holes 21, the quantity of fastening through-hole 23 is multiple and is uniformly distributed in a circumferential direction, the quantity of Blind locating holes 21 is two and is being diametrically opposed to one another；
Described method also uses elastomeric material pad 3 and elastomeric material pad broaching cutters 1；
Described elastomeric material pad 3 is annular, it is provided with equally distributed multiple pad through hole 33 in the circumferential and at two the location protrusions 31 being diametrically opposed to one another, described location protrudes 31 for coordinating with described Blind locating holes 21, inner periphery place on the tabular surface of the both sides of described annular is provided with the circumferential flange 34 projected axially outward from described tabular surface, the centre of point described elastomeric material pad 3 is pad through hole 32, described circumferential flange 34 on the tabular surface of described pad through hole 32 through both sides and the body of described annular；
The inner periphery of described elastomeric material pad broaching cutters 1 is formed with broach teeth 11；
In the step that mould 2 assembles, by sandwiched described elastomeric material pad 3 between multiple described moulds 2, the location making described elastomeric material pad 3 is protruded 31 and is coordinated with the described Blind locating holes 21 on mould 2, the outer circumference surface of described circumferential flange 34 coordinates with axially extending bore 24 inwall of mould 2, and pad through hole 32 to be directed at the fastening through-hole 23 of mould 2, and pass described fastening through-hole 23 and described pad through hole 32 with turnbuckle 4 and fasten with tightening nut 41, now, described elastomeric material pad is compressed；Afterwards, the mould 2 after utilizing elastomeric material pad broaching cutters 1 to be pulled through assembling so that broach teeth 11 passes through the mould teeth groove 22 of mould 2 thus cutting elastomeric material pad 3 to form the shape corresponding with mould 2；
In the step of described cutting, being unclamped gradually by described tightening nut 41, and extracted out by turnbuckle, now, described elastomeric material pad recovers shape gradually；Then the cutting utilizing belt cutting tool to carry out being perpendicular to axial direction at described elastomeric material pad place, thus carrying out the cutting of Timing Belt when without being unloaded by mould, obtains the Timing Belt of required width.
Wherein, the quantity of described fastening through-hole 23 is six.
Annular belt body, multiple band teeth along belt body inner peripheral surface equidistant arrangement, with flexible nylon cloth cladding on tooth surface, the core rope that lays along the circumferencial direction of belt body, being positioned at core rope surface has the good black of cohesive to increase layer sizing cladding core rope, belt band back of the body chromatic colour sizing material covers, thickness of belt 3～10mm partially thicker in conventional synchronous band.
Band tooth infantees can be carried out rubber cement process, when band tooth infantees carries out rubber cement process, it is important that to consider its wearability, flexibility, have good cohesive with belt body.Nylon cloth is made to soak into completely in rubber cement bucket with special impregnation equipment, it is then transferred to compression roller, control gel content and the thickness of nylon cloth by regulating the spacing of compression roller, then nylon cloth is transferred to drying unit and repeats said process and carry out face glue impregnation operation.By immersing glue process, not only make band tooth infantees have good cohesive, also there is good wearability.
Band tooth infantees is cut into preliminary dimension after processing through rubber cement.With ultrasonic bonding, two opposites of predetermined nylon cloth are welded together, the band tooth infantees cloth set of cylinder can be obtained.
To be enclosed within the mould needing molding with tooth infantees cloth set, then when keeping tension force constant, the core rope through adhesive treatment is wrapped in outside band tooth infantees.
Enhancement layer black sizing material selects neoprene to be main body, adds certain compounding ingredient and strengthens implant, making sizing material hardness at 75SHA °, and hot strength is at more than 18MPa.After selecting tradition mixing facilities mixing, make black sizing material hardness that black sizing material to be rolled into the film that thickness is 0.8mm, film is attached on the made-up belt of forming, smooth during film laminating, it is to avoid gauffer affects thickness of belt.Ground floor film first with second layer film tail can not overlapping can not be not in place；Ruler and cut-off knife must be utilized during severing.
Being placed on by gum cover in steam vulcanization (cure) tank and preheat, preheated rear enclosure outside the made-up belt of forming, made-up belt outer wall and gum cover inwall gap are about 5mm, large flat bread on pad.Then at 0.4MPa steam pressure, carrying out sulfuration sizing under the 5min time in vulcanizing tank, in High Temperature High Pressure type-approval process, these fluidised rubber forms rubber layer and forms band tooth with the rubber being pressed into together with tooth infantees in teeth groove.
After sulfuration sizing, cylindrical shape belt body is taken out from vulcanizing tank, allows its natural cooling 20 DEG C～30 DEG C, it is carried out the band red gum forming of the back of the body.Red glue is selected natural in main rubber, adds certain compounding ingredient and strengthens implant, making sizing material hardness at 45SHA °, and permanent deformation is below 25%, and hot strength is at more than 20MPa.After selecting the tradition clean free of contamination mixing facilities of inner chamber mixing, red sizing material is rolled into the film that thickness is 1.1mm, film is attached on the made-up belt of forming, film is smooth when fitting, and with roller compaction, avoiding gauffer to make rubber surface have gas to blast, the band back of the body produces bubble and delamination occurs.Being placed on by gum cover in steam vulcanization (cure) tank and preheat, preheated rear enclosure outside the made-up belt of forming, made-up belt outer wall and gum cover inwall gap are about 5mm, large flat bread on pad.Then vulcanize in vulcanizing tank under certain sulfide stress, time, in High Temperature High Pressure sulfidation, these fluidised enhancement layer rubber and band are carried on the back rubber, are tightly coupled to each other between cotton rope and band tooth, and co-vulcanized.
Band cylinder to band back-grinding to specific thickness, is then cut by one fixed width, cutting machine is loaded onto water injector cutter are cooled down, it is to avoid cutter both sides do not have rubber to be bonded at surface, affect belt band side surface attractive in appearance after terminating by second time sulfuration.
As it has been described above, have the advantage that by the Timing Belt of preparation of the present invention
1), band tooth has good wearability and dynamic property；
2), by the research and development with the red sizing material of the back of the body, making the band back of the body have good wearability and elastic modelling quantity, band back of the body color is not easily contaminated；
3) band tooth sizing material and band gum material good bonding, and band gum material is evenly distributed.
