Abstract
The utility model discloses a kind of automatic heat preserving bell mechanism being applied to aluminium alloy casting industry, comprise bell, described bell is divided into left bell (2), right bell (3) and connecting with linkage support (12) respectively, and this linkage support is connected with power source (9) by intermediate transmission assembly; Described power source is cylinder, and this cylinder is electrically connected with pedal switch (7) by the time relay (8).The utility model can not only realize split type bell quickly opening and closing and decrease the monolateral working space position of original monoblock type bell.Solve the diffusion of holding furnace thermal source, reduce holding furnace energy consumption, reduce holding furnace high temperature to the heat radiation of operator, make operator can relatively be in good working environment.And increase aluminium liquid heat insulation effect, reduce the consumption of the energy, it is more effective, simple, practical, convenient to operate.
Description
Technical field
The present invention relates to a kind of holding furnace, particularly relate to a kind of heat insulation furnace cover mechanism being applied to aluminium alloy casting industry.
Background technology
At present, in aluminium alloy casting industry, it is poured into a mould heat insulation furnace cover mechanism used and is all designed to often open monoblock type bell.Because temperature of aluminum liquid during cast is generally all in 720-740 DEG C, under heat insulation furnace cover is in normally open, this thermal source gives out amount of heat, particularly be in scorching temperature in summer, workshop cast regional temperature is general all at 45 DEG C, and even sometimes close to 50 DEG C, holding furnace is other hot hard to bear especially.Operator is in this environment and works, and is great challenge, in the high temperature time, has operator to occur heatstroke phenomenon successively to the muscle power of personnel and fitness.And Chang Kailu lid makes temperature of aluminum liquid easily scatter and disappear, particularly winter, the temperature difference was large, and for guaranteeing the temperature reaching manufacturing requirements, resistance wire, not stopping heating, increases energy consumption greatly.The opening and closing of this heat insulation furnace cover are all control by scooping screw rod by hand, and operation is inconvenience comparatively.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency, and provides a kind of and can automatically control bell folding, reaches the automatic heat preserving bell mechanism of effectively insulation.
Object of the present invention is realized by following technical scheme: automatic heat preserving bell mechanism, comprises bell, and described bell is divided into left bell, right bell and connecting with linkage support respectively, and this linkage support is connected with power source by intermediate transmission assembly; Described power source is cylinder, and this cylinder is electrically connected with pedal switch by the time relay.
After adopting structure of the present invention, power source work drives linkage support to stretch by intermediate transmission assembly, again left bell, right bell are opened or closed, the automatic open-close of split type bell is controlled with this, need according to scooping aluminium technique and carried out effective insulation, bell quickly opening and closing can not only be realized and decrease the monolateral working space position of original monoblock type bell.Solve the diffusion of holding furnace thermal source, reduce holding furnace energy consumption, reduce holding furnace high temperature to the heat radiation of operator, effectively isolated heat radiation, makes operator can relatively be in good working environment.And increase aluminium liquid heat insulation effect, reduce the consumption of the energy, it is more effective, simple, practical, convenient to operate.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail.
Fig. 1 is the mounting structure schematic diagram of automatic heat preserving bell mechanism of the present invention.
Fig. 2 is bell in Fig. 1 schematic diagram when being in closed condition.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, the present invention is applied to the automatic heat preserving bell mechanism of aluminium alloy casting industry, comprise bell, described bell is divided into left bell 2, right bell 3 (being semi-circular) and connecting with linkage support 12 respectively, and this linkage support 12 is connected with power source 9 by intermediate transmission assembly; Described power source 9 is cylinder, and this cylinder 9 is electrically connected with pedal switch 7 by the time relay 8.
Wherein, described linkage support 12 is shearing fork telescopic formula linkage support (for " scissor " operating principle), described intermediate transmission assembly is the sub-assembly of screw rod 5 and nut 10, the middle part of this screw rod 5 is connected with power source 9 (i.e. the piston rod of cylinder), and the two ends of this screw rod 5 are connected with linkage support 12 and use nut 10 to lock.This linkage support 12 is contained on bracket base 4, and this power source 9 is contained on power source base 6, and bell, power source base 6, bracket base 4 are all contained on (insulation) body of heater 1.On described body of heater 1 and between shearing fork telescopic formula linkage support 12 and the screw rod 5 of intermediate transmission assembly, limited block 11 is equipped with at place, to carry out effectively spacing to the left bell 2 of bell with the folding of right bell 3, the interlock of shearing fork telescopic formula linkage support 12.
Described cylinder 9, the time relay 8, pedal switch 7 all connect with microcomputer controller, utilize microcomputer controller (i.e. PLC device), realize the automatic open-close of bell with pedal switch and time relay co-controlling.Step on pedal switch, left and right bell is opened automatically, after scooping aluminium liquid, has arrived the setup times (according to scooping aluminium situation setup times) on the time relay, alarm automatic alarm.After warning, PLC device arranges 5s safety time, and the left and right bell of bell is closed automatically.
The present invention, according to the uncertainty scooping the aluminium frequency in real process, determines that bell folding must flexibly, rapidly.And the folding direction of monoblock type bell is opened from above, opens from a left side, opens all do not reach requirement from the right side.And because of the limitation of bell surrounding area, monoblock type is opened and is taken up space comparatively large, can cause interference.The present invention also combines the object reached and designs on the basis of these features, overcomes these not enough problems.
First, according to the load-bearing of (insulation) bell, cutting, welding production shearing fork telescopic formula linkage support 12, be connected this linkage support with the sub-assembly of nut 10 by screw rod 5, and be fixed on bracket base 4.These two semi-circular left and right bells 2,3 are welded in linkage support respectively, and linkage support and bell will carry out reserved opening respectively, use as the thermocouple placed on thermal insulation furnace body.Be arranged on the boiler face of thermal insulation furnace body by the bell made and linkage support, bell and boiler face have the gap of 6-8mm, are convenient to the folding of left and right bell.At welding stationary power source, bell edge base 6, and cylinder is installed.Cylinder has band magnetic and pooling feature, is beneficial to the folding of bell and spacing.According to the finish dimensional of thermal insulation furnace body, determine the stroke that bell is opened, and be welded and fixed limited block 11.Connect source of the gas, PLC device, utilize the folding of the time relay, the left and right bell of pedal switch co-controlling.
