Abstract
The utility model relates to a continuous extruding and coating device, in particular to a continuous extruding machine with a support roller; a frame is provided with an extruding roller and a die cavity; a sliding groove is arranged on the frame and internally provided with the extruding roller and the support roller; load is applied on the extruding roller; the support roller is arranged along the direction opposite to the load and supported on the surface of the extruding roller; and the extruding roller is contacted with the support roller in a pressing way. By adopting the continuous extruding machine with the support roller, the radial load of the extruding roller is born by the support roller, so that the diameter of the extruding roller is much smaller than that of the existing extruding wheel, and the length of the extruding roller is greatly lengthened; therefore, the extruding wheel shaft system is simplified, and the safety performance of operation of the device can be greatly improved. The extruding roller belongs to a tooling quick-wear part, and the size of the extruding roller is greatly reduced, so that the using cost is correspondingly reduced.
Description
Technical field:
The utility model belongs to non-ferrous metal processing and cables manufacturing field, relates to being used for the continuously extruded and continuous equipment that coats.
Background technology:
The main shaft of existing continuous extruder all adopts the direct supporting structure of bearing, sees Fig. 1,2.Owing to need torque transmitted and nip load all very big, so that the diameter of main shaft also needs is very big.Easily lost efficacy and the high contradiction of the big cost of size in order to solve the main shaft working portion, main shaft is designed to combining structure, is about to working portion and is designed to annulus, be called squeegee roller 20, then part strings such as itself and axle sleeve are enclosed within on the mandrel 21, again by hydraulic nut 17 with its clamping.Only changing squeegee roller 20 when like this failure damage taking place gets final product.
The weak point of this structure is:
Axis system is too complicated, and needing super-pressure pretension extruding wheel shaft is 19, changes squeegee roller 20 inconveniences.
Because the effect that main shaft bears driving torque and the dual load of extruding radial power causes main shaft short service life.
Thermograde is big in squeegee roller 20 courses of work, and the life-span is short.
Main shaft can not be long, bearing supports that spacing can not be excessive, otherwise radial compression power can cause main shaft to produce huge moment of flexure and destroy, and therefore can not realize that the wide multiple-grooved (more than 3) of taking turns is continuously extruded, and this mode is to realize the optimal selection of wide and flat production.
For continuous coating, because squeegee roller 20 diameters are big, the working portion of die cavity 9 and mould 13 are difficult to arrange that cause the runner of extrusion metal long, resistance is big, and energy consumption is big.
Summary of the invention:
The purpose of this utility model is to address the above problem, and a kind of continuous extruder that has backing roll is provided, and is simple in structure, and security performance improves, and reduces use cost.
The technical scheme that the utility model is adopted for achieving the above object is: a kind of continuous extruder that has backing roll, relate to compression roller and die cavity are housed on the frame, have chute on the frame, compression roller and backing roll are installed in the chute, load is applied on the compression roller, backing roll is arranged in the direction upper support relative with load on press roll surface, and compression roller compresses with backing roll and contacts.
Described hydraulic jack drives and connects die cavity pretension piece, die cavity pretension piece pretension die cavity and compression roller, and the gap that keeps suitable between die cavity and the compression roller is constant.
Installation mold in the described die cavity, mould adopts extrusion die or coating mould.
The continuous extruder of the utility model band backing roll, the radial load of compression roller can be born by backing roll, so that the diameter of compression roller is compared the reduced of existing squeegee roller is a lot, the length lengthening is a lot, this structural change of compression roller, bring a lot of advantages:
Extruding wheel shaft system obtains simplifying, and the complicated operations such as hydraulic nut that originally need to change no longer need.
Owing to no longer need super-pressure pretension extruding wheel shaft system, make the operation of equipment and the security of running improve greatly.
Compression roller belongs to frock class consumable accessory, because the reducing significantly of size, makes that use cost is corresponding to reduce.
The application of backing roll makes the stress of compression roller more reasonable, and load no longer is the alternating force effect, has reduced intensity tired, the creep equivalent damage, and frock is increased service life.
Needn't adopt very large diameter compression roller again, the use of path compression roller makes the circumference of compression roller race be heated evenly, the probability of the heat fatigue damage of reduction.
It is very long that compression roller can design, use for the charging of many bars like this and become possibility, mean original with the super wide product that could produce on the super large continuous extruder, on small-sized extruder, just can realize now with very low energy consumption and very low frock loss, reduced production cost, economic benefit is very remarkable.
This structure can have two kinds of mode of operations promptly to coat and push, one-machine-multi-function.The path compression roller substitutes conventional extruded wheel shaft system, make the frock practical cost reduce, and demolition and maintenance is very convenient.

The specific embodiment:
A kind of continuous extruder that has backing roll as shown in Figure 3, relate to head section mechanism, compression roller 10 and die cavity 9 are housed on the frame 1, have chute 4 on the frame 1, by bearing block 3 compression roller 10 is installed in the chute 4, in the chute backing roll 2 is installed simultaneously, load 16 is applied on the compression roller 10, backing roll 2 is arranged in the direction upper support relative with load 16 on compression roller 10 surfaces, compression roller 10 compresses with backing roll 2 and contacts, hydraulic jack drives and connects die cavity pretension piece 8, die cavity pretension piece 8 pretension die cavitys 9 and compression roller 10, and the gap that keeps suitable between die cavity and the compression roller is constant.
Pattern two is coating mode of operation head section mechanisms as shown in Figure 5, during cladding applications, earlier heart yearn 14 is passed body, bar material 11 is sent between backing roll 2 and the compression roller 10 equally, compression roller 10 rotations are brought bar material 11 into body, when bar material 11 arrives material blocking block, change flow direction and flow into die cavity 9, flowing at last to flow out by mould 13 in die cavity 9 forms tubuloses and is enclosed in around the heart yearn 14, forms coated prod 15.
When the utility model head section mechanism is used shown in Fig. 6,7, power outputs to decelerator 7 from motor 6, being delivered to extrusion roll shaft from decelerator 7 through universal coupling 5 again is 18, compression roller 10 and backing roll 2 are in contact with one another, wherein backing roll is to move reciprocatingly along the chute on the frame 14, and promptly backing roll 2 floats, and load 16 is applied on the compression roller 10, backing roll 2 is arranged on the direction relative with load 16, and is supported on compression roller 10 surfaces.Die cavity pretension piece 8 earlier with die cavity 9 pretensions, makes gap between die cavity 9 and the compression roller 10 suitable and remain unchanged under the hydraulic jack effect.
