Abstract
The invention discloses a production process of a PU synchronous belt. The production process comprises the following steps of a. putting a production mold on a forming machine and winding cable core uniformly; b. covering a vulcanized coat on the production mold after the cable core is wound; c. putting PU raw materials into the production mold; d. subjecting the production mold to high temperature vulcanization shaping in a vulcanizing machine and fixing a shape; e. starting a cooling mode to reduce the temperature of the production mold after the vulcanizing time reaches; f. taking the synchronous belt out from the mold; and g. cutting and detecting residual waste materials at two sides of the synchronous belt. The production process is simple; and a produced product is stable in performance.
Description
Technical field
The present invention relates to Timing Belt technical field, relate to more specifically a kind of PU Timing Belt production technology.
Background technology
PU Timing Belt inner core generally has zinc-coated wire, coppered steel wire, Kraft bracing wire core, glass fibre core etc., outer attached PU glue-line.Be divided into two types of one side cingulum and two-sided cingulums.The former is mainly used in single shaft transmission, and the latter is multiaxis or reverse drive.PU Timing Belt is taked to be meshed with the teeth groove of belt wheel with tooth and is transmitted motion and power, is a kind of engaged transmission, thereby has the various advantages of gear drive, chain transmission and Belt Drive.In order to guarantee that it still keeps good locomitivity in transmission, PU Timing Belt need to have higher antiwear property and resistance to tension, traditional PU Timing Belt is by arranging Kraft bracing wire core, the inner cores such as glass fibre core significantly reduce the telescopicing performance of Timing Belt, thereby make still to keep in Timing Belt high-speed drive good precision, but, because the telescopicing performance of PU glue is better, by directly outer being attached on inner core of PU glue, if its product uses for a long time under the larger environment of the temperature difference, segregation phenomenon between the different material layer that easily occurs causing because of the phenomenon of expanding with heat and contract with cold, for this reason, how a kind of stable performance is provided, adaptable PU Timing Belt has become people is worth the problem of inquiring into.
Summary of the invention
Object of the present invention is exactly the deficiency in order to solve prior art and a kind of production efficiency of providing is high, make simple, the stable PU Timing Belt production technology of properties of product of production.
The present invention adopts following technical solution to realize above-mentioned purpose: a kind of PU Timing Belt production technology, it is characterized in that, and it comprises the steps:
A, production mould is put to uniform winding core above forming machine;
B, the production mould being wound around after core is added to cover sulfuration overcoat;
C, PU raw material are put into production mould;
D, production mould in vulcanizer after high temperature vulcanized moulding solid shape;
After e, cure time reach, open cooling mode and reduce production mould temperature;
F, Timing Belt is taken out in mould;
G, by the cutting of unnecessary Timing Belt both sides waste material, detect.
As further illustrating of such scheme, in described processing step d, its curing temperature is 180-200 ℃, keeps 25-35min.
At the temperature-fall period of described processing step e, be to adopt mechanical water-cooling pattern, production mould temperature is dropped to 20-30 ℃, keep 35-45min.
Described PU raw material adopt TPUE rubber and look mother.
The TPUE rubber containing in described PU raw material and look mother's percentage by weight are: TPUE rubber 90-98%, look female 2-10%.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
The present invention adopts and first on production mould, is wound around core, and adds after cover sulfuration overcoat, recharges PU raw material and enters in production mould, through after high temperature vulcanized, cooling process, obtains PU Timing Belt product, and its mechanical property is good.
The specific embodiment
Below in conjunction with specific embodiment, specific embodiment of the invention scheme is described in further detail.
A kind of PU Timing Belt of the present invention, comprises Timing Belt main body and the Timing Belt main body bottom surface tooth bar corresponding with the teeth groove of belt wheel, and in the main body of tooth bar, continuous separate is furnished with multiple band teeth, and multiple main bodys with tooth and tooth bar are the integrated formed structure that adopts same material.
The production technology of described PU Timing Belt, it comprises the steps:
A, production mould is put to uniform winding core above forming machine;
B, the production mould being wound around after core is added to cover sulfuration overcoat;
C, PU raw material are put into production mould;
D, production mould in vulcanizer after high temperature vulcanized moulding solid shape, its curing temperature is 185 ℃, keeps 30min;
After e, cure time reach, open cooling mode and reduce production mould temperature, adopt mechanical water-cooling pattern, production mould temperature is dropped to 25 ℃, keep 40min;
F, Timing Belt is taken out in mould;
G, by the cutting of unnecessary Timing Belt both sides waste material, detect.
PU raw material adopt TPUE rubber and look mother, wherein, TPUE rubber and look mother's percentage by weight is: TPUE rubber 90-98%, look female 2-10%, the present embodiment adopts TPUE rubber 97%, look mother 3%.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
