Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to an apparatus and method of use thereof for continuously extruding metal from granular, powdered or solid feed materials, which apparatus comprises: (a) during operation: 1. a rotatable wheel member arranged to be rotated by a drive device and having a circumferential groove continuous therearound; (b) a rotatable wheel member arranged to be rotated by a drive device; a closed passage is provided in the wall of said f, extending circumferentially of said wheel member and having a portion projecting partially radially into said groove with a slight working clearance from the side wall of said groove; (c) a cooperating shoe member disposed at an inlet end of said passageway for causing feed material to flow into said passageway at said inlet end thereby rotating toward an outlet end of said passageway in an opposite direction; (d) carried by the shoe member and set at the outlet end thereof and projecting radially into the passage; (e) an abutment member that prevents the passage of feed material frictionally conveyed in the channel by the wheel member, so as to generate an extrusion pressure in the passageway at its outlet end; a die carried on a member and having a die orifice opening from said passageway at said outlet end thereof, through which said supply is conveyed and frictionally compressed by rotation of said wheel member within said groove when driven; It includes a die member through which material is continuously compressed and extruded and delivered through an exit hole to the shoe member.

The present invention particularly relates to a method of manufacturing rotatable wheel members for use in rotating, friction-type, continuous extrusion equipment.

In operation of such an extrusion device, the parts forming the passageway adjacent to the outlet end thereof are subjected to extremely high applied loads and extremely high applied temperatures. Of the parts subjected to such high stresses (mechanical and thermal), the parts which suffer the most wear or damage are the stationary feed material engaging parts of or in combination with said stationary shoe member, especially The parts on the abutting member, the die member and the stationary parts supporting these parts.

In order to provide better protection against worn and damaged surfaces and parts, the abutment member, the die member surface and its supporting parts are provided with separate parts rigidly but removably attached to the stationary shoe member. Built as replaceable parts.

To reduce the working temperature of such replaceable parts,
These parts (d) have internal cooling passages through which cooling water is circulated. However, such cooling means cannot be said to be extremely effective for the following reasons, namely: ( 1) The small size of these components and the high mechanical loads they are subjected to significantly limits the size of the cooling passages that can be formed within them and the proximity of those passages to the heat source, making it difficult to use adequate cooling water. (11) The materials used in these small components (such as high speed steel) have relatively low heat transfer properties.

Since the heat dissipation is not sufficient depending on the cooling water, the flow of plastic at the tip of the abutment member becomes hot due to the excessive rise of the abutment member at its free end, which connects to the bottom of the groove in the wheel member. Become. This severely limits the service life of the abutment member and significantly limits the operating time of the device between successive instances in which the abutment member must be replaced. This reduces the amount of extruded product produced due to downtime during which the equipment is not operational.

In addition, when used over a long period of time, there is a risk that the extrusion die may be heated to such a high temperature that its mechanical strength is impaired, creating a risk of die deformation and/or increased straddle wear.

In particular, as a result of experiments with various different arrangements of the internal cooling passages in the abutment members, very satisfactory results have been obtained, which can be attributed to one completely different arrangement for the cooling of the abutment members. Ta.

Such different arrangements, and various modifications thereof, are both described and claimed in the pending parent patent application No. 0-11983, from which this application has been divided. The intended use of the parent invention is to develop such rotary, friction-type, continuous extrusion equipment over long periods of time and with long operating lives for parts of the equipment which are subject to high mechanical and thermal stresses. to enable operation.

The beneficial results obtained from the use of the invention (the parent application) can be enhanced by its use in combination with the invention of this divisional application.

According to the invention, a method for manufacturing a rotating wheel member adapted for use in a rotating, friction-type, continuous extrusion device comprises: (a) a continuous radially extending groove formed in a cylindrical circumference; (b) + rotating the wheel on a rotating shaft; (c) a tool of a predetermined end shape is fitted to the wheel and adapted to the circumference of the annular metal mass, and the tool is stepped in the radial direction so as to continuously rotate the wheel; the step of machining a working groove of a predetermined desired cross-sectional shape in the circumferential portion of the annular metal block; , of a configuration substantially equivalent to the configuration of the predetermined feedstock to be extruded within the apparatus when equipped to be manufactured into a wheel member; and of a predetermined end of the tool; The shape is
A shoe member is used in the device to close the end of an arcuate passageway formed in the machined groove by a shoe part cooperating with the cylindrical circumference of the wheel member when the device is energized. substantially equivalent to the shape of the predetermined adjacent member for

It is desirable that the annular metal mass attached to the wheel groove be in good thermal relationship with the wheel.

An annular metal mass mounted in the wheel groove includes a first predetermined metal mass residing concentrically with the wheel in the wheel groove and surrounded by a second predetermined metal sheath. The second predetermined metal defines the machining groove and is in good thermal relationship with the first predetermined metal.

The annular metal attached to the wheel groove is located concentrically with the wheel at the bottom of the wheel groove and is covered by a first predetermined ring of metal and a second predetermined metal ring. the first predetermined metal is in good thermal relationship with the second predetermined metal, and the second predetermined metal is Limit the groove.

Preferably, the first and second predetermined metals are each a product of thermal conductivity and specific heat per volume that is greater than the specific heat of the material of the wheel.

Advantageously, said first predetermined metal product is larger than said second predetermined metal product.

In carrying out the method of the invention, said wheel is mounted for rotation in a rotary extrusion device and is rotated in rotation, and said tool includes an adjacent member of said device, said adjacent member said when said wheel is rotated. It is advanced radially into the annular metal mass.

The invention also provides a wheel member made by the method according to the invention.

Other aspects and advantages of the invention will be apparent from the following description and claims.

The invention will now be described with reference to the accompanying drawings with reference to embodiments of a continuous extrusion device.

1 and 2, the illustrated device is carried in bearings (not shown) and coupled via an interlock (not shown) to an electric motor (not shown), thereby An interlock (not shown) to an electric drive motor (not shown) to be driven during operation at a selected speed within the range of 0 to 2 ORPM (greater speeds are also permissible).
1 includes a rotatable wheel member 10 coupled via and carried in bearings (not shown).

This wheel member is provided with a groove 12 extending around its periphery, and a radial cross section of this groove is shown in FIG. The deep part of the groove has parallel annular sides 14 that connect with the radial bottom surface 16 of the groove.

The tapered multi-shaped intermediate portion 18 of the groove has an inverted truncated conical surface 2
Form 0.22.

A stationary shoe member 24 mounted on the lower pivot pin 26 extends around approximately one quarter of the circumference of the wheel member 10 and cooperates closely therewith.

The shoe member is held in the operative position shown in FIG. 1 by a retractable stop member 28.

The shoe member includes a centrally (axially) circumferentially extending protruding portion 60 which extends into the groove 12 of the wheel member 10 with a slight axial or lateral clearance 62° 64 on either side thereof. □Stand out. This protruding part 6
0 is constituted in part by a series of exchangeable inserts and includes a radially oriented abutment member 66, an abutment member support 38 downstream of the abutment member, and a It includes a die block 40 (having an extended die 42) and an arcuate wear member 44 upstream of said die block. Member 44
Upstream of the shoe member, an integrally formed inlet portion 46 completes an arcuate passageway downstream to the front face 54 of the abutment member 66, which is vertically disposed below the feed material cone 52. Extending from the oriented feed material inlet passageway 50 and around the wheel member. This passageway is shown in FIG.
It has a radial cross section defined by an inner surface 56 of the.

The abutting member 6, the die block 40, and the die 4
2 and arcuate member 44 are all constructed of a suitable hard, wear-resistant metal, such as high speed steel.

The shoe member has an exit hole 58 that aligns with a corresponding hole formed in the die block 40 through which the extruded delivery metal product 61 (
For example, a round wire) is sent out.

As the wheel member 10 rotates, the powdered feed material introduced from the hopper 52 via the inlet passage 50 into the inlet end of the arcuate passage 48 is spread over the length of the arcuate passage 48 by the moving groove surface of the wheel member. 1 in a counterclockwise direction in FIG. 1, and is formed into a mass and consolidated to form a solid mass of solid metal in the lower portion of the passageway adjacent to the die block 40. This solid metal mass is continuously pushed against the abutting member under a large pressure by the frictional resistance of the moving groove surface. This pressure is sufficient to force the metal mass through the orifice of the extrusion die, thereby providing an extruded product that is discharged through the shoe member and the hole 58 in the die block. In a special case, this production product includes bright copper wire made from small cut pieces of wire that constitute the feed material.

The water vibro 2 mounted around the lower end of the shoe member 24 has an outlet nozzle 64 located and fixed on the side of the shoe member located adjacent the wheel member IDK.

This nozzle is aligned so that, when the pipe is supplied with cooling water, it directs a jet of water directly onto the downstream portion of the abutment member located within and abutting the groove 12 of the wheel member 10. Thus, the tip of the free end of the abutment member (this is where the heat of the thick part is generated during operation) and the joint surface and groove of the wheel member are suspended over them from the jet directed towards them. Cooled directly by water flow.

The die block 40 has an internal water passageway (not shown) and a supply of cooling water to seal off the product leaving the die and extract some of the heat retained within the product. However, the abutment member is not provided with such an internal passage. The strength of this member is therefore not reduced by providing internal water cooling means to cool the member.

If desired, cooling of the device may be accomplished by providing a cooling water sprinkler 65 on the hollow grate 52 to deliver a volume of cooling water into the precise passageway 48 along with the powdered feed material. promoted by

In FIG. 2, the solidified metal mass in the extrusion zone adjacent die block 40 is indicated at 66. From this metal mass, a manufactured product is extruded through an extrusion die 42 by pressure in this area. This pressure acts to force a quantity of gold nugget between the side walls of the trench and each opposing surface of the die block and abutment member. This extruded metal gradually accumulates radially to form scrap metal pieces or "beams." In order to prevent these pieces of scrap metal from growing too large to handle or control, a plurality of laterally oriented teeth 70 or a flared wall forming the mouth 18 of the groove 12 is used. It is fixed at 20.22. The teeth are evenly spaced around the wheel member, with teeth on one wall facing teeth on the opposite wall. If desired, teeth on one wall may be staggered to alternate with teeth on the other wall.

Regarding the operation, the inclined surface 7 of the dice block 40
2 deflects the extruded scrap piece 68 obliquely within the path of each set of moving teeth 70. Interdiction of this scrap piece 68 by the moving teeth causes the scrap piece to cut or shred the extruded metal within the gap. These scrap pieces are thus removed as soon as they have moved sufficiently far in the radial direction, blocked by the moving teeth. In this way the "beam" is prevented from reaching an unmanageable size.

The teeth need not be sharply shaped and may be fixed on the wheel member 10 in any suitable manner, such as by welding.

Figures 3 and 4 show other teeth secured in a similar manner to other types of suitable surfaces of the wheel member 10.

In these alternative devices, the outer surface of the wheel member 10 cooperates with a correspondingly shaped surface of the cooperating shoe member 24, thereby providing control of the beam in a particular desired manner. In FIG. 6, the pegs are grown purely transversely or axially until they are stopped by radially projecting teeth, where they are shredded from the extruded metal in the associated plow opening.

In FIG. 4, the flash is grown diagonally (as in FIG. 2) but is blocked by teeth projecting radially from the surface of the wheel member 10.

For various reasons that will be apparent from the description below, it is desirable to process the extruded product (wire 61) from the continuous extrusion device described above in an extruded product processing device prior to delivery to the product collection and storage device; Sometimes even necessary.

Additionally, it may be desirable or advantageous to process the extruded product while it is maintained at elevated temperatures from the continuous extrusion process in which it was produced.

Such processing equipment can, for example, provide extruded products with a wide variety of surface finishes (eg, drawer finishes) and more uniform outer diameters or gauges. Such processing equipment may also be used to provide finished products of varying cages and/or tolerances at different times from the same continuous extrusion product. For such purposes, the processing apparatus includes a single drawing die through which the extruded product is passed without breaking and then pulled to tension to achieve the desired size, tolerance and/or texture. or quality finished products. The use of such processing equipment to process extruded products may result in long periods of time where the continuous extrusion die 42 of the continuous extrusion equipment is discarded due to excessive enlargement of the die hole due to wear during use. conjugate for the use of b]

Additionally, such processing equipment can accommodate various gauges, tolerances, and/or
``1. High quality production products can be manufactured on behalf of each other.

An example of a continuous extrusion system that combines a continuous extrusion device and an extruded product processing device will be described below with reference to FIG.

The system shown in FIG. 5 includes the continuous extrusion device 100 described above.
-, which can be modified as described below if desired, and the copper wire 102 produced by this device can be moved by a tensioning pulley device 106 to a sizing die 104 (the case and size as desired). (decreasing to a low value), the wire passes through the kink of the tensioning pulley system several times until it passes through the storage device 108 and into the coil winding i 110.

Pulley system 106 is coupled to the output shaft of electric torque motor 112 , and energization of the motor is provided and controlled by controller 114 . The control device includes (a) a wire tension detection device that engages with the wire 102 at a position between the extrusion device 100 and the sizing die 1071 and provides an electric signal as a signal due to the tension of the wire 102 when exiting the extrusion device 100; The first obtained from 118
(b) extrusion device 100 in response to electrical signal 116;
in response to a second electrical signal 120 obtained from a temperature sensor 122 that measures the temperature as the wire 102 leaves.

The controller 114 is responsive to the second (temperature) signal 120 in its output circuit to control the particular wire 10 at the particular temperature generated by the second (temperature) signal.
A function generator 124 is provided to provide a sixth electrical signal that determines the yield stress tension for the tension. Third electrical signal 126
is sent as a reference signal to a comparator 128 (also forming part of said control device), where said first (
The tension) signal 116 is compared to the third signal (yield stress tension). The output signal of the comparator constitutes a signal for controlling the torque of the torque motor.

In operation, the torque motor operates at a particular temperature when a particular wire leaves the extruder 100.
It is energized to a thickness sufficient to maintain the tension in the wire leaving the extrusion device at a predetermined magnitude value below the yield stress tension for this particular wire.

Although the two series of explanations have described a structure in which a water jet is used to cool the tip of the contact member, jets of other cooling fluids (or even cooling gas) can also be used in place of water. Liquefied gas can also be used as appropriate.

The following matters can be considered with respect to the teeth 70 for removing stains in the above-mentioned methods. The working distance between the tip of each tooth 70 and the adjacent opposing surface of the stationary shoe member 24 is also not very important, and this dimension may not exceed 1 mm to 2 mm depending on the specific role of the device. (c) The greater the number of teeth spaced around each side of the wheel member 10, the smaller the length of the "beam" removed from each tooth. ) These teeth may be made of any suitable material, such as tool steel, and any conventional method may be used to secure the teeth to the wheel member.

The ability of this device to deliver an acceptable production product from a granular or powdered feed material is achieved through arcing within a pressure generating area located immediately forward (upstream) of the forward surface 54 of the abutment member 66. The radial depth - straddle height) of the passages 48 can be considerably improved by making them disappear relatively abruptly in the direction of rotation of the wheel member 10 in a suitable manner (as shown in the figures).

A removable die block 40 is disposed circumferentially coextensive with that area, and said progressively decreasing shape of the radial depth of the arcuate passage is the die block facing the bottom of the groove 12 of the wheel member 10. This is achieved by appropriate shaping of the surface of the 40 people.

The said surface 40A of the die block is preferably so as to obtain a feed metal flow pattern in said area when the apparatus is operated that is very similar to that achieved when solid feed material is used instead. Can be shaped. In the preferred embodiment shown in the figures, this surface 40A comprises a planar surface angled at a suitably small angle tangent to the bottom of the groove 12 at the point where it contacts the abutment member 36 at its front face 54.

This angle ideally corresponds to (b) the radial cross-sectional area of the passageway 48 at the inlet end of said area (i.e. upstream of the die block 40 (11) of the apparent density of the feed material entering the area at the artificial end (in the radial cross-section adjacent to the end)
The density of the fully consolidated feed material located adjacent to the front surface 54 of the

In one preferred embodiment, the planar surface 40A of the die block is such that the area of the abutment member exposed to the feed metal material at extrusion pressure is within the passageway 48 at the inlet end of the area (i.e. the upstream end of the die block). is inclined at an angle equal to 1/2 of said radial cross-sectional area.

If desired, in another embodiment, the surface of the die block facing the bottom of the groove 12 extends in the manner described above only over a major portion of the circumferential length of the groove extending from said upstream end of the die block. The portion of the die block that is sloped and located here immediately adjacent the front surface 54 has a surface that is parallel (or nearly parallel) to the bottom of the groove.

Groove 1 obtained by the above-mentioned shaping of the surface 40A
The greater penetration of die block 40 into 2 also provides increased physical resistance to undesired extrusion of flash-forming metal through gap 32, so that the feed metal material intended to form such flashes. The amount of is greatly reduced. Furthermore, the entry of the die block into the groove 12 is as follows:
It reduces (a) the total work acting on the feed material, (b1 the amount of peg generated, and (C) the bending moment applied to the abutting member by the pressure metal. Furthermore, the planar working surface 40A on the die block The selection lowers the manufacturing cost of the die block.

In the above description, the wheel member 10 is driven by an electric drive motor at a speed within a defined range, or, in other similarly functioning continuous extruders, by a hydraulic drive and operated at the appropriate operating speed. do.

Instead of introducing additional cooling water into the passageway 48 via the sprinkler 65, the bottlings 52 and the passageway 50, such additional cooling water may be provided by filling the passageway with granular feed material but not completely congealing. (
e.g. via a passageway 67 formed in the shoe member 24).
be introduced.

The highly effective cooling effect provided by this invention is
Due to the fact that the heat absorbed by the portion of the wheel system located temporarily adjacent to the hot metal in the enclosed extrusion area upstream of the abutment member is (through the action of both heat conduction and rotation of the wheel member) to a cooling zone located downstream of the abutment member.
In this cooling zone, the cooling fluid is supplied in large quantities and flows over a relatively large area of the wheel member passing through this cooling zone, thereby absorbing a high proportion of the heat absorbed by the wheel member in the hot extrusion zone. Pull it out from there.

In this cooling zone, access to the wheel element is less restricted and a relatively large surface of this element is freely available for cooling purposes. This means that an extremely small and enclosed cooling surface (
That is, by direct contact with the die block and the contact member).

As previously mentioned, the cooling surfaces of these parts are strictly limited by the need to preserve the mechanical strength of these parts while safely withstanding the extrusion pressures exerted on them.

The transfer of heat absorbed by the wheel member to said cooling zone is achieved by good heat transfer and good specific heat (per unit volume).
This is greatly improved by using the wheel member of metal with a .

However, since the wheel member is made of a physically strong metal (eg tool steel) for reasons of adequate mechanical strength, it has relatively poor thermal conductivity. Thus, the ability of the wheel member to transfer heat to the cooling zone is greatly increased by closely fitting the wheel member with an annular band of metal with good heat absorption and thermal conductivity, such as a copper band, for example. be done.

Preferably, such a thermally conductive band is constituted by an annular band fixed around the periphery of the wheel member, at least in part in which the circumferential groove provides the passageway 48 (the shoe member). Preferably, the portion of the wheel member is formed by:

If the extrusion of this machine is suitably made of a metal with good thermal properties, the heat-conducting band is made of the same metal (for example copper) as the extrusion.

In other cases, said thermally conductive band is embedded within or overlaid on a second annular band, said second annular band being made of the same material as the extruded product of said machine and said These two bands, which are brought into contact with the tip portion of the abutment member, are made of different materials.

The metal used for the heat transfer band is selected to have a higher product of thermal conductivity and specific heat of unit volume than tool steel;
and contains the following materials (the higher the product, the higher the product): copper, silver, beryllium, gold, aluminum, tungsten, rhodium, iridium, molybdenum, ruthenium, zinc and iron.

The heat transferred from the extrusion zone to the cooling zone by such a thermally conductive band is determined by the radial cross-sectional area of the band, p, and increases as the cross-sectional area of the bracket increases. Thus, for a given cross-sectional dimension measured transverse to the circumference of the wheel member, the greater the radial depth of said band;
The rate at which heat is transferred to the cooling zone by the wheel members is high.

For said wheel member having an effective diameter of 233 mm and a rotational speed of 1 °C PM, said heat conductive band being made of copper with a U-shaped radial cross section, said cooling from the extrusion area by said wheel member. The heat transfer rate of the area is
R'' and this rotation alone causes the abutment member 36 cooperating with the wheel member to protrude into this copper band as the radial depth or distance changes, i.e. the copper remaining at the bottom of the circumferential groove 12. Calculations were performed as changing as the radial thickness "T" of the band changes. These calculations are based on the copper band having a generally circular interface in radial section with the adjacent part of the wheel member (tool steel). Therefore, the radial cross-sectional area of the copper band “A
” is the radial thickness I of copper at the bottom of the groove 12
It changes non-linearly depending on TJ.

8 10.4 In 71 cases of 1 with such a wheel member, the radial thickness T of the steel kund at the bottom of the groove 12 is 2 mm, and the rotational speed of the wheel member is 1. When extruding a wire with a diameter of 4 mm at a speed of 150 m/s, 47/min
Heat is extracted in said cooling zone from the wheel member and the abutment member at a speed of 10 kW by cooling water flowing at a low velocity such as, and a jet velocity of approximately 800 m/min onto the surface to be cooled in said cooling zone. I will provide a.

This heat transfer rate is approximately 2.3 kW as a result of conduction through the heat transfer band to the cooling zone, through the adjacent wheel member parts and the abutment member, to the extrusion zone. As a result of the conduction of heat caused by the temperature gradient existing between the cooling zone and the cooling zone, a heat transfer rate of approximately 2.3 kW reached the cooling zone.

This measured extraction rate of heat by the cooling water flowing in the cooling zone is approximately 1
．． This shows a very good contrast with the maximum heat transfer rate of 9 kW.

FIG. 6 is a graph showing that the rate of heat transfer from the wheel members and abutment members in the cooling zone varies as the flow rate of cooling water supplied to the zone changes.

The extruder described above with reference to the accompanying figures was actually tested using the copper heat transfer band described above, which band is shown at 74 in FIG. 10 and for convenience shown in broken lines in FIG. (FIG. 2 further shows that when the copper band 74 is shown as a solid line,
It can be seen that the figure shows a cross section taken along green - H).

FIG. 7 is similar to FIG. 2 and shows a modified embodiment of the wheel member 10. In this embodiment, a solid annular band 76 made of copper having a roughly rectangular radial cross-section is mounted and clamped between the cooperating steel members 78 of said wheel member, so that said member When the supported drive shaft is driven by the drive motor, the shaft is driven by the member. The band 76, at least initially, has a small internal groove 76A that spans the tight joint between the two cheek members 78. This groove prevents any metal of the band 76 from getting between these cheek members during assembly of the wheel member 10. Complementary frustoconical surfaces 76B and 78B on the band and cheek members, respectively, form the wheel member 10.
facilitate assembly and disassembly of these parts.

A circumferential groove 12 is formed in the copper band by pivoting the shoe member 24 around its pivot pin 26 toward the periphery of the rotary wheel member 10, thereby causing the tip of the abutment member 66 to pass through the copper band. , thereby causing the steel band to be machined progressively deeper to form said groove 12 therein.

FIG. 8 is a variation of that of FIG. 7, in which the thermally conductive band includes a composite annular band 80 with an inner core 82 of a metal (such as copper) having good thermal properties. , surrounded by a sheath 84 of the same metal (such as zinc) that is extruded by the machine, in good thermal relationship with this metal.

FIG. 9 shows another modification of the modified embodiment of FIG. 7,
Here, the thermally conductive band includes a composite band 86, the radially inner annular part 88 of which is made of a metal with good thermal properties (such as copper) and extruded by the machine. It is surrounded with a good thermal relationship by a radially outer monkey-shaped piece 90 of the same metal.

Metals that can be extruded by the extruder as mentioned above are copper and its alloys, aluminum and its alloys, zinc, silver and gold.
