Abstract
The utility model relates to a compressing device of a continuous covering machine, which is provided with a crankshaft, a connecting rod acting on a die holder of the covering machine and a crankshaft driving device, wherein, bearing journals on both ends of the crankshaft are supported on the wall of the covering machine, and at least one end of the crankshaft extends out of the wall of the covering machine to be fixedly connected with the crankshaft device, and the connecting rod is hinged with a crank web of the crankshaft. The compressing device has reasonable structure, and adequately makes use of the amplification effect of the crankshaft connecting rod mechanism on the force, thereby reducing the requirements of the crankshaft driving element, so that the element is convenient to be processed, and the price is low; and moreover, the continuous and stable work of the covering machine can be ensured.
Description
Technical field
The utility model relates to a kind of hold down gag of coating machine, belongs to the servicing unit of coating machine.
Technical background
Coating machine is as the new technology of development in recent years continuously, and it is extensively applied to the making of bimetallic materials such as aluminium Baogang.The example that is made as with aluminium Baogang, continuously the groundwork principle of coating machine is: by the shelves material piece that stops aluminium bar circular motion that is provided with on the groove established on the squeegee roller surface and the die holder, under the continuous rotating conditions of squeegee roller, the frictional force of cell wall constantly acts on the aluminium bar, make the preceding aluminium bar of shelves material piece be subjected to above immense pressure of 500 MPas and the above high temperature of 450 degree, thereby reach the state of plastic deformation, around steel core, form aluminum-clad steel wire by the mould bag that is arranged on die holder then.And above-mentioned die holder one end bearing is being fixed on the pivot of fuselage, the other end is pushed down with hold down gag, to overcome the huge mould power that rises that die holder is subjected to, and rational gap between assurance squeegee roller and the die holder, if thrust is little, die holder will pivot, and the aluminium material just overflows from the gap that increases, and coating machine can not be worked continuously.
At present, above-mentioned hold down gag both domestic and external all is to adopt hydraulic jack to promote piston rod to act directly on the die holder, but because the restriction of machine space, the hydraulic jack size is less, so it must use the above pressure oil of 70 MPas; Yet just belong to Superhigh Pressure Hydraulic System greater than 32 MPas usually, its required precision to Hydraulic Elements is very high, and existing Hydraulic Elements often do not reach requirement, reveal very serious, part even owing to do not reach required thrust influences the work of continuous coating machine.
Summary of the invention:
The purpose of this utility model is to provide a kind of liquid machine interlock hold down gag of continuous coating machine, this device need not to use Superhigh Pressure Hydraulic System by the change of crankshaft-link rod hold-down mechanism and drive unit, has reduced the required precision to Hydraulic Elements, hydraulic system leakage is little, and working stability is energy-conservation.
The utility model is that the technical scheme that its purpose of realization is adopted is: a kind of liquid machine interlock hold down gag of continuous coating machine, and it comprises bent axle, acts on the connecting rod and the crank driven mechanism of coating machine die holder; Wherein, the bearing journal of described crankshaft two end is supported horizontally inside the coating machine fuselage wall of its both sides, and has at least an end bearing axle journal to run through that fuselage wall stretches out and affixed with crank driven mechanism, and described rod hinge connection is in the crank web of bent axle.
As preferred embodiment of the present utility model: described crank driven mechanism comprises pull bar and hydraulic jack, described pull bar one end and crankshaft support axle journal epitaxial part are affixed, the piston rod of one end and hydraulic jack is hinged, and described hydraulic jack is articulated in the coating machine fuselage wall.
Between described pull bar and the crankshaft support axle journal for and socket and fix by key.
As further improvement of the utility model: the effect end face of described connecting rod is hemispherical structure.
In order to guarantee the steady of work, the bearing journal of the crankshaft two end described in this preferred embodiment runs through the fuselage wall of its both sides respectively, and correspondence is provided with two cover crank driven mechanisms.
In the utility model when work, drive pull bar by the piston rod of hydraulic jack and rotate, and makes crank up downward, thereby drive link moves downward and is pressed onto on the coating machine die holder, and the holding position is constant, guarantees the continuous operate as normal of coating machine.Said mechanism has made full use of the amplification of crankshaft connecting rod system to power, make the hydraulic jack that drives its rotation that middle pressure on the ordinary meaning only need be provided, just can make crankshaft link rod motion arrive desired location, thereby reduced requirement to Hydraulic Elements, solved the leakage of oil problem, hydraulic system seldom needs supplementary pressure oil and saves energy and reduce the cost.The utility model mechanism is simple, and element is easy to process, and is cheap.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of the utility model hold down gag;
Fig. 2 is that the A of crank driven mechanism among Fig. 1 is to view.
Among the figure, 1 is bent axle; 1-1 is the bearing journal of bent axle; 1-2 is the crank web of bent axle; 2 is connecting rod; 3 is die holder; 4 is pull bar; 5 is hydraulic jack; 6 is fuselage wall; 7 is key.
The specific embodiment
As shown in Figure 1: the liquid machine interlock hold down gag of continuous coating machine of the present utility model comprises bent axle 1, connecting rod 2 and the two cover crank driven mechanisms of being made up of pull bar 4 and hydraulic jack 5; Wherein, the bearing journal 1-1 horizontal supporting of described bent axle and passes fuselage wall 6 respectively and stretches out affixedly with pull bar 4 on the fuselage wall of its both sides 6, and described connecting rod 2 one ends act on coating machine die holder 3, and the other end is articulated in the crank web 1-2 of bent axle.And described connecting rod 2 acts on the end face of die holder 3 is hemispherical structure.
As shown in Figure 1 and Figure 2: two cover crank driven mechanisms are installed in the both sides of fuselage respectively, pull bar 4 one ends of described every cover crank driven mechanism and the socket of crankshaft support axle journal 1-1 epitaxial part are also fixing by key 7, the piston rod of one end and hydraulic jack 5 is hinged, and hydraulic jack is articulated in coating machine fuselage wall 6.
In the utility model when work, drive pull bar 4 rotations simultaneously by the piston rod of both sides hydraulic jack, make bent axle 1 revolution downwards, thereby drivening rod 2 withstands coating machine die holder 3 downwards, and the holding position is constant, guarantees the continuous operate as normal of coating machine.
After adopting said structure, after tested, the hydraulic jack of both sides only need provide the oil pressure about 10 MPas, and promptly above-mentioned middle pressure can drive bent axle and arrive desired location, guarantees the continuous operate as normal of coating machine.
The utility model is rational in infrastructure, and is easily manufactured, satisfactory for result, helps guaranteeing continuous, the stable work of coating machine.
