Abstract
The utility model relates to equipment for continuous extrusion and continuous coating, in particular to a vertical continuous-extrusion sheathing machine for forming a four-passage cone die. An extrusion die cavity is arranged between two extrusion wheels; a retaining block is arranged at the product outlet side at the central connecting line of the two extrusion wheels; the two extrusion wheels are arranged on two main shafts respectively; the two main shafts rotate relatively at identical speed; two circumferential extrusion wheel grooves are arranged on the two extrusion wheels respectively; the four extrusion wheel grooves are communicated with four inlets on a converging chamber respectively; four inlets are uniformly distributed on the same circumference of the converging chamber; and the outlet of the converging chamber is communicated with a clearance between a convex die and a concave die. In the utility model, the four-passage cone die forming method is adopted, and the material in the tooling is guaranteed to flow uniformly so that the production of the large-diameter pipe material and large-diameter coating can be realized. By adopting the cone flow-type die structure forming method, the material can be tightly and firmly coated with the surface of the core wire and the drawing procedure is reduced. The same equipment and the same tooling are adopted for producing the pipeline and the sheath line, therefore, one equipment has multiple functions.
Description
Technical field:
The utility model belongs to non-ferrous metal processing and electrical cable-making apparatus, relates to being used for the continuously extruded and continuous equipment that coats.
Background technology:
The existing continuous extrusion cladding equipment that is used for non-ferrous metal processing and cables manufacturing generally all is to adopt one or two blanks 2 as shown in Figure 1, utilizes a squeegee roller 1 to drive.At first heart yearn 4 is passed die cavity 7 during work, then blank 2 is delivered between pressure wheel 3 and the squeegee roller 1, rotating generation frictional force by squeegee roller 1 brings blank 2 between pressure wheel 3 and the squeegee roller 1 into, pressure wheel 3 imposes severe pressure to blank 2 when rotating with blank 2, make blank 2 distortion and more firm attached on the squeegee roller 1, after blank 2 runs into material blocking block 11, material blocking block 11 forces blank 2 that violent distortion takes place, change flow direction and flow to die cavity 7, because the drastic deformation of frictional force and blank 2 produces heat, make material softening produce plastic deformation.Blank 2 enter converge chamber 6 after, under the HTHP effect, continue to flow out forming protecting pipe and wrap in heart yearn 4 outsides and become jacket from the slit between punch 5 and the die 8.
Exist bigger gap between jacket that this kind method forms and the heart yearn 4, in subsequent handling,, make jacket and heart yearn 4 closely in conjunction with forming last sheath product through drawing die 10 drawings.
The weak point of this pressing method and device structure is:
1, because from the one-sided feeding blank of die cavity, runner is asymmetric, causes flow velocity irregular, the circularity of protecting pipe and wall thickness are difficult to control, can't realize the coating of large scale (diameter is greater than 70mm) sheath.
2, because punch 5 is necessary for hollow structure for use in passing heart yearn 4, be subjected to the restriction of mould strength, punch 5 must have enough wall thickness proof strengths, but also causes simultaneously the protecting pipe that squeezes out excessive with the gap 9 of heart yearn 4, must add the pine that the tube reducing operation could arrive requirement
Tightness.And excessive sizing reduction can cause the sheath hardening, thereby has lost pliability, the finished product poor performance.
3, outfit of equipment is a horizontal type structure, and floor space is big.For the bigger equipment of specification, product center line height, thus cause inconvenient operation.
Summary of the invention:
The purpose of this utility model is to address the above problem, a kind of four-channel tapered die forming vertical continuous extrusion cladding machine is provided, can push large scale jacket (diameter is greater than 100mm), and can directly protecting pipe be coated on the outer surface of heart yearn, need not tube reducing, simple and compact equipment structure, floor space is little.
The technical scheme that the utility model is adopted for achieving the above object is: the four-channel tapered die forming vertical continuous extrusion cladding machine, extrusion die cavity is between two squeegee rollers, material blocking block is positioned at the products export side of two squeegee roller lines of centres, on two main shafts that two squeegee rollers are installed respectively, two main shafts are relatively with the speed rotation, have two circumferentially extruding races on two squeegee rollers, four the extruding race respectively with converge the chamber on four imports be communicated with, four imports are distributed on and converge on the same circumference in chamber, and the chamber of converging outlet is communicated with gap between punch and the die.
The gap is communicated with between the outer block ring that is equipped with of the described chamber of converging outlet, block ring and punch and die.
Gap between described punch 5 and the die 8 is the rake angle annular space.
Two main shafts of described jacket machine rotate synchronously by gears engaged.
Described jacket machine adopts vertical layout, spindle axis line vertical ground, and power section and running part place underground.
The utility model adopts the squeegee roller of a pair of synchronous rotation, and each is taken turns along circumferentially respectively opening two or three extruding races, can feed four or six roots of sensation blank simultaneously.Four blanks race of under the effect of pressure wheel, nipping simultaneously, in race through behind about 120 degree cornerites since material blocking block stop that under the driving of squeegee roller frictional force, blank enters in the die cavity that is contained on the boots seat.Because the effect of heating element heater in frictional heat and the die cavity, material softening produces plastic deformation.Four blanks are respectively from four symmetric points A of die cavity, and B, C, D enter and converge the chamber, and seam under HTHP is even by making flow velocity behind the block ring, flow out by the rake angle annular space between punch and the die at last, form local Taper Pipe.This Taper Pipe can progressively become isodiametric pipe under the effect of circular symmetric stress, the outside that wraps in heart yearn forms jacket.Owing to adopted the four-channel tapered die forming method, guaranteed the uniformity that the frock internal material flows, large diameter tubing of production and major diameter are coated be achieved.Use coning tower tray formula mould structure and be shaped and make coating and the heart yearn surface that material can close and firm, and needn't increase drawing procedure again.Produce tubing and RVV and adopt same equipment, frock of the same race, one-machine-multi-function.
Die cavity dismounting and boot last die holder are opened employing hydraulic jack structure, can automatically working, and laborsaving fast.Squeegee roller is installed on the prestressing force axis system, produces pretightning force by hydraulic nut, to obtain high service life.Equipment in the running, two squeegee rollers rotate relatively, and its component that boot last die holder is applied makes the trend of the oriented device interior motion of boot last die holder, and it is a lot of that the relative original structure of the required coupling mechanism force of boot last die holder is reduced, because locking cylinder uses low pressure, make device energy conservation safety.It is very reasonable that simultaneously this layout makes the direction of input and output material of production line.The jacket machine is vertical layout, and floor space is little, and power and running part place underground, operates highly lowly, and simultaneously this layout and structure also are convenient to the replacing of die cavity 7 and mould.The utility model can be realized the serialization production of products such as big specification electrical cable aluminium sheath, metal sheath.
