Description
Technical field
The invention belongs to the driving-belt production technical field, be specifically related to a kind of be used to the produce jacketed mold of driving-belt and the supporting vulcanizing tank that designs at this jacketed mold, also relate to the sulfuration process of having used this jacketed mold of driving belt simultaneously.
Background technology
Driving-belt except can free speed change, the far and near transmission, also have noise little, simple in structure, change advantages such as convenient, in large-scale agricultural machinery, industrial equipment, foreign-going ship and field facility, all be widely used.We can say, from original machinery to modern automation equipment, the figure of the driving-belt that grows on trees.In recent years, the demand of super long type driving-belt increases rapidly, and the trend of the leading position of dominating the market is arranged greatly, and mould diameter used in the driving-belt production and processing is also therefore increasing.
At present, though each is variant for the frock of each driving-belt manufacturing enterprise and technology, but what adopt mostly all is the monotubular wall mould, as shown in Figure 1, mould cylindrical shell 3 two ends of individual layer are fixed with end casing 1, be provided with cover plate pillar 2 between two end casings 1, end casing 1 combines as a whole with mould cylindrical shell 3, can not separate or can not partly separate.The structure of each used vulcanizing tank of enterprise is also more approaching, the air storage chamber that generally includes tank body, cover and be arranged on the tank body bottom, and the supporting plate gland seal of air storage chamber top has pore on the supporting plate.Before the sulfuration, need the driving-belt base substrate of mould, mould outer wall and made-up belt set of molds one end of curing bag formation are lifted on the supporting plate earlier down, and at its top cover upper cover plate.Mould inner wall, top blind flange and supporting plate surround the interior pressure chamber of mould, and interior pressure chamber is communicated with air storage chamber by the supporting plate pore, press in the chamber in the steam inlet of interior pressure steam through linking to each other with air storage chamber charges into.Curing bag, mould top blind flange and vulcanizing tank constitute the external pressure chamber of mould jointly, and the external pressure chamber has independently steam inlet equally.During sulfuration, interior pressure chamber and external pressure chamber all are full of steam, and interior pressure steam provides curing temperature, play main sulfurization; External pressure steam mainly provides sulfide stress, plays auxiliary sulfurization simultaneously.Press chamber and external pressure chamber can not scurry vapour mutually in will guaranteeing in the sulfidation, can reach normal cure efficiency.
Obviously, for the monotubular wall mould, the quantity of steam that the big more then mould inner pressure of diameter chamber need be used is also big more.Now the monotubular wall mould with external diameter (diameter) Φ 2.0m, high 1.0m, cylindrical shell wall thickness 0.02m is an example, calculates to be full of and presses the required quantity of steam in chamber in it:
The volume of whole inner chamber:
The shared volume of upper and lower side cover plate:
The volume that advances steam drain of 12 Φ 0.1m on the upper and lower side cover plate:
Three partial volumes add up to the rear interior cavity quantity of steam to be: 3.02-0.12+0.0038 ≈ 2.9m
3
Be every sulfuration once, press in this monotubular wall mould the chamber to need 2.9m approximately
3Saturated vapor, such steam consumption is the huge test to the air feed boiler for the enterprise of large-scale production super long type driving-belt, has also become the stumbling-block on the road of industry energy conservation reduction of discharging.Show according to statistics, whenever adopt 1 ton of saturated vapor and need 160～170 yuan of comprehensive financial resources, that is to say that an every sulfuration of mould once just has hundreds of unit and is wasted.In addition, sulfuration finishes a large amount of saturated vapor in back and is bled off in vain, also will take a large amount of operating times in the time of the waste resource, and then influence production efficiency.
Except waste steam resource, limit because of being subjected to himself structural factor, existing monotubular wall mould has also seriously restricted the utilization ratio of vulcanizing tank.In the actual vulcanisation operation, one jar of one mould gum cover formula sulfurizing pot vulcanization technology the most commonly, the diameter of driving-belt mould is suitable with the vulcanizing tank tank diameter usually in this technology, but the mode of production of using the big tank diameter little band tube of sulfuration (mould diameter is much smaller than the vulcanizing tank tank diameter) is also arranged.Obviously, the latter be low load with strong power way, extremely impracticable in practical operation: as both to have wasted the steam resource, and wasted equipment again.So occur such one act through regular meeting in the actual production: after placing a mould in jar, certain space is also left in the mould outside, wants to force down several little moulds and improves the utilization rate of vulcanizing tank, how also to fail to lay down by size restrictions.In fact, the vulcanizing tank quantity of most of enterprises is all very limited, and the tank diameter of vulcanizing tank also is changeless, soon wastes resource and but can only hope " jar " to heave a sigh.Certainly, also having enterprise the collocation of several small size moulds to be put in the vulcanizing tank of (placing a side by side) big tank diameter vulcanizes, though this so-called one jar of multimode can improve sulfuration efficient to a certain extent, but under the increasing trend of super long type driving-belt, the sulfuration ability of its vulcanizing tank has just seemed some deficiency.
