Abstract
Continuous extrusion means in which aluminium or copper feedstock with a nominal diameter approximately 40% greater than the width of the circumferentially extending groove in a continuous extrusion wheel is fed from a feed reel to a centreless lathe or shaving machine set to machine the feedstock to a diameter corresponding to the width of the groove. In thereby removing the surface layer, surface impurities are removed and feedstock with a clean, non-oxidised surface is delivered directly to the groove without the intervention of feed rollers liable to cause distortions in the feedstock whilst ensuring that substantially constant forces arise between the machined-to-size feedstock and the walls of the groove. This reduces any tendency of irregular feed toward the associated abutment and thus enhances the constancy of the product quality as well as avoiding problems arising from oxidation and/or surface imperfections.
Description
Technical field
The present invention relates to a kind of method and apparatus that is used to make continuously extruded products.
Background technology
EP071490 has illustrated a kind of equipment of making continuously extruded products, and it comprises a feed reel, is used for giving the groove that circumferentially extends with the general raw material of circular cross section basically in runner.
Summary of the invention
According to an aspect of the present invention, process equipment is positioned for receiving raw material and unloading the raw material that processes in the groove of circumferential extension from feed reel, wherein process equipment is arranged to remove at least one deck top layer and forms a friction tight circular cross section that is of a size of in the groove that circumferentially extends from raw material.
Preferably process equipment comprises and is not in the mood for lathe.
Selectively, process equipment comprises a shave head.
Conform with the destination, each the drive motor electronic type that is used for feed reel, process equipment and runner connects into the speed that makes feed reel and the speed of process equipment is adjusted into consistent with runner speed.
According to a further aspect in the invention, a kind of method that is used to make continuously extruded products is provided, it comprises: give process equipment with the general raw material of circular cross section basically from feed reel, raw material is processed to remove one deck top layer at least and to form a charging that is of a size of the friction tight circular cross section in the groove that circumferentially extends, the raw material that processes is directly delivered to the groove of circumferential extension and driven the runner that carries the raw material around the groove that circumferentially extends that processes from process equipment, make it contact a supporting surface (abutment) and discharge to form an extruded product by a mould.
Preferably, raw material is an aluminium.
Selectively raw material is a copper.
Conform with the destination, process equipment at typical diameter be realize on the raw material of 12.7mm+/-tolerance of 0.1mm.
In one embodiment, extrusion equipment comprises, in a sequence, a feed reel, process equipment, a continuous extruder and a product reel.
This feed reel comprises a drive motor and arranges to be used to carry the aluminum feedstock of the aluminium wire shape of about circular cross section to arrive a lathe of not being in the mood for drive motor by guide wheel.
This is not in the mood for lathe closely in abutting connection with continuous extruder ground location and carry the raw material that processes directly in the groove of circumferentially extruding of a parallel sided, and this groove is formed on the runner of an electric motor driven continuous extruder.
This continuous extruder is discharged extruded product from a mould that is communicated with the passage the mould body, fix the supporting surface that the groove that this mould vicinity one extends into circumferential extension is interior, and extruded product is transported to by in the electric motor driven product reel.
Corresponding velocity of electrons control device is relevant with the motor of the speed at the speed that respectively has the feed reel place, the speed of not being in the mood for lathe and reel place, and these speed electronic types are connected in the runner rotating speed of continuous extruder.
In operating process, nominal diameter for+/-0.2mm or be that the aluminum feedstock of the axial width big by 4% (just about 2mm) of groove is sent into from feed reel and is not in the mood for lathe than runner, this is not in the mood for lathe and is used for raw material is worked into the diameter that is equivalent to well width, thereby removes one deck top layer from raw material.During removing the top layer, surface impurity is removed and the raw material that will have a clean non-oxidation surface is delivered directly in the groove, and need not insert the feed roller that is easy to cause distortion in raw material in the power that produces substantial constant on the cell wall of guaranteeing between raw material that is worked into close tolerance and cell wall.This reduced the tendency of sending to any irregular raw material of supporting surface around the groove and thereby improved the constancy of extruded product quality, also avoided because oxidation and/or intrinsic surface blemish causes in two steps of separating problem.
Obvious metal except that aluminium, for example copper can be transferred with the bar that control speed is cut off by fixed length as raw material and extruded product, rather than be wound on the looping disk.
