Description
Technical field
The utility model belongs to industrial dry tack free apparatus field, is specifically related to the roller bed type conveying mechanism of a kind of foundary industry continous way core dry tack free stove.
Background technology
In casting industry and relevant industries, continous way core dry tack free stove is for the hard sand process characteristic of fat and exploitation specially, the energy-efficient skin drying equipment of design, adopt electric heater for heating, be applicable to the resin sand of all size and the type of water-glass sand, core and the dry special equipment of other material table face, it is high that it has heat utilization efficiency, temperature is uniform and stable, production lot is large, automaticity advantages of higher, the conveying mechanism of existing continous way core dry tack free stove is all to adopt plate chain type conveyer structure, be arranged on the bottom of dry tack free stove, adopt pitch P=100mm all-wing roller chain, for baffle plate and cast sand box, the conveying of core.Due to plate chain type conveyer self structure design reasons, its equipment fault shows as the fault of transmission chain more, and fault has carrier bar to damage, transmission chain is deviate from carrier bar trough, transmission chain comes off on power chain, joining link ruptures, encircle in succession damage etc.Once there is equipment fault in apparatus for production line running, stop production and carry out repair and maintenance processing completely with regard to needs, quite waste time and energy, thereby cause plate chain type conveyer fault rate high, maintenance cost cost is high, and production efficiency is low, and its service life and reliability are reduced.Chinese patent Granted publication number is CN 202639229 U, and Granted publication day is on January 2nd, 2013, and utility model name is called the conveying mechanism of sand core watch dried furnace, has provided a kind of belt type conveyer structure of sand core watch dried furnace.This utility model is by changing to Belt Conveying by existing conveying mechanism, like this will be in the skin drying operating process to core workpiece, can easily not produce scuffing to half-finished surface of core workpiece, avoid to a certain extent the scuffing of connecting gear to core workpiece, improve operating efficiency, for enterprise has created profit.
But the limitation of above-mentioned patented technology is: design only adopts belt-type transmission, avoid to a certain extent the scuffing problem of connecting gear to core workpiece, because some small-sized, light-duty core workpiece that the limitation of belt-type transmission is only applicable in casting industry are carried.Some large-scale, heavy core workpiece that are not easy in casting industry are carried, and particularly comprise that the combined type of baffle plate, cast sand box and casting mold core workpiece is carried, and the maximum load weight of combination can reach 6 tons of left and right, can not carry with belt-type mode of movement.Separately, the preference temperature of core dry tack free stove cast form hot air drying process: 180-200 degree, feed belt is worked and is prone to aging, phenomenon of rupture for a long time at 180-200 degree temperature, cause greatly reduce the service life of belt, this stops production and carries out repair and maintenance processing and change feed belt with regard to needs, thereby cause belt type conveyer maintenance cost cost high, production efficiency is low, service life and reliability reduce.
Summary of the invention
The purpose of this utility model: for addressing the above problem, the utility model, for the deficiencies in the prior art, provides the roller bed type conveying mechanism of a kind of foundary industry continous way core dry tack free stove.
Technical scheme: for achieving the above object, the utility model adopts following technical scheme:
The roller bed type conveying mechanism of continous way core dry tack free stove for a kind of foundary industry, described roller bed type conveying mechanism is through the head and the tail inside below of dry tack free furnace body, comprises that frame main beam, housiung separator, frame pillar and base anchor, driving wheel tensioning bolt, flange rotary shaft roller, rolling bearing are formed by the roller bearing units of usheing to seat, driven sprocket, threephase asynchronous, cycloidal planetary gear speed reducer, drive sprocket, roller chain, lower margin set bolt, basic pre-embedded steel slab, lower margin hold-down nut.It is characterized in that the utility model adopts roller chain single chain driving form, frame pillar and base anchor are fixedly mounted on basic pre-embedded steel slab, frame main beam is laterally evenly provided with the flange rotary shaft roller of rollgang, driving wheel tensioning bolt is installed on the top at frame main beam two ends, bottom is provided with as the threephase asynchronous of Power Drive Unit, cycloidal planetary gear speed reducer, because threephase asynchronous, cycloidal planetary gear speed reducer and frame main beam integrated design, spacing are less, therefore adopt the transmission of roller chain interval.The reductor of Power Drive Unit adopts cycloidal planetary gear speed reducer, has the advantages that volume is little, speed ratio is large, bearing capacity is large, versatility is good.
Described roller bed type conveying mechanism, is characterized in that the utility model comprises frame main beam, housiung separator, frame pillar and base anchor, driving wheel tensioning bolt composition.By rollgang press manufacturing technique requirent in place below the head and the tail inside of dry tack free furnace body after, the lower margin set bolt of base anchor is welded on basic pre-embedded steel slab, adopt lower margin hold-down nut fixed form to regulate its height.Regulate lower margin hold-down nut height, ensure that roll surface height meets the desired absolute altitude technical requirement of production line.
Described roller bed type conveying mechanism, is characterized in that the utility model comprises that flange rotary shaft roller, rolling bearing are the roller bearing units of usheing to seat (model: UCP-308), driven sprocket composition.
Described roller bed type conveying mechanism, is characterized in that the utility model comprises threephase asynchronous (model: Y90L-4), cycloidal planetary gear speed reducer (model: BLY B3-71-1.5), drive sprocket, roller chain (model: 16A-1, pitch 25.4mm) composition.
As optimization: roller bed type conveying mechanism described in the utility model adopts roller chain single chain driving mode, by outer link with inner link is hinged forms, roller empty set is free to rotate on sleeve, friction and wear while engagement to reduce, and can relax impact, thereby can avoid or reduce the generation of equipment fault, greatly reduce equipment failure rate.Changing roller, only need to unclamp 4 bolts of both sides rolling bearing pedestal replaceable, and repair and maintenance is in time convenient.The threephase asynchronous of two drive units, cycloidal planetary gear speed reducer are arranged on the bottom at frame main beam two ends, each flange rotary shaft roller that drives respectively front and rear by roller chain, when one of them breaks down, also can hang up roller chain for driving whole conveying mechanism at middle driven sprocket, it is timely, time saving and energy saving that repair and maintenance facilitates.
Beneficial effect: the utility model is by changing to roller bed type conveying mechanism by existing plate chain type conveyer structure, like this will be in the skin drying operating process to core workpiece, reduce equipment failure rate, and be convenient to carry out repair and maintenance replacing, quite time saving and energy saving, maintenance cost cost is low, has improved production efficiency and operating efficiency, and its service life and reliability have obtained greatly and improved.Mechanism of the present utility model horizontal force is even, therefore core workpiece material (maximum load weight can reach 6 tons of left and right) is carried steadily, kinetic energy consumes low.And there is driving wheel tensioning bolt to be used for regulating the loose of carrier chain in the design and installation of frame both ends.
