Description
Technical field
The utility model relates to field of metal material heat processing technology, is specifically related to a kind of metallic fiber drawing mould universal adjustment device.
Background technology
Metallic fiber unique chemical composition makes it have seven big functions: anti electromagnetic wave, antistatic, conduction, high temperature resistant, anti-cutting and friction, can filter and inhale sound insulation.
The acting body of metallic fiber uniqueness aspect anti-electromagnetic radiation is present: contain the woven fabric of 1% metallic fiber, the electromagnetic shielding rate is 88.86% under the environment of 1800MHZ; The woven fabric that contains 3% metallic fiber has 98.43% shielding rate under 1800MHZ; The woven fabric that contains 5% metallic fiber has the electromagnetic shielding rate more than 99%.Owing to the difference of dB value, it is also different that it shields electromagnetic efficient aspect high frequency.At the Future New Energy Source automotive field, because electromagnetic generation directly has influence on the healthy of driver and passenger; On military equipment,, all need to use metallic fiber to play the effect of radiation proof and shielding in order to reach the purpose of disturbing radar test.
Metallic fiber belongs to one of state key tackling key problem scientific research project, introducing on the basis of advanced foreign technology by how tame scientific research departments such as the Chinese Academy of Sciences, Chinese University of Science and Technology, by deep exploration and research, make it that very big breakthrough all arranged from the technical equipment to the product processing technique, indexs such as its tensile strength, percentage elongation are pressed the GB/T4240-93 standard detection, all meet corresponding data demand.But these achievements only are the samples that obtains in the laboratory, the uniformity of product quality in the time of can not guaranteeing to produce in batches, and technical elements is still immature.
The forming process of metallic fiber is the wire with thick diameter, the process that progressively attenuates by drawing repeatedly; Just thick object attenuates it and prolongs by extruding.The pressure that is subjected to around the wire is consistent to belong to reasonable drawing; The pressure that wire one side is subjected to then belongs to unreasonable drawing greater than opposite side, because a side overload behavior certainly will damage tensile strength wiry, also damages pushing used mould simultaneously, as causes the very fast distortion of die hole.
Existing wire-drawing equipment operation principle is that the mould group is placed multistage step place, makes module aperture and cone pulley terraced steps level, concentrates colony's drawing, realizes the high efficiency industrialization.
Analyze theoretically, this principle is set up, but in practice weak point is arranged, and reason has 5:
1. the pedestal of placing mould is fixed on the lathe bed, and the position of placing mould also is predefined, and the position in this explanation mould aperture is also fixed, and this has just produced die hole and wire can produce decentraction in drawing process.
2. mould is after being assembled on the pedestal fixing position, in the dynamic drawing process of wire, can not be definitely and each step of cone pulley all be on the same horizontal line.
3. the installation accuracy of mold base can not satisfy the trend naturally of metallic fiber fully.
4. microfilament twines on the cone pulley ladder by spiral, realizes colony's drawing, so microfilament pass the mould empty position can not each bar all accurately with silk move towards naturally match.
5. microfilament owing to need spiral to twine drawing, certain gradient must be arranged, and the mould aperture does not have gradient perpendicular to the cone pulley ladder by the ray of die hole.
Even suppose above-mentioned reason 2, reason 3 fixed-site, precision and assembly precision all reach designing requirement, and the trend naturally of silk is a unknown number, does not still realize rational drawing.
Learn from above-mentioned analysis, the metallic fiber equipment of domestic production at present, drawing process is still continued to use common wire-drawing equipment theory, and just drawing process is silk drawing for guiding along the fixed mould hole, this is a crin, non-colony drawing (product quality shows not obvious but the reasonable drawing of can not saying so); Promptly at present the domestic wire product of producing has changed the structure of chemical composition of metallic fiber part element because irrational drawing, can't truly realize radiation proof and function of shielding, can only satisfy high temperature resistantly, and rub resistance filters, and inhales the sound insulation function.And microfilament is concentrated drawing, and product quality then requires higher.
Summary of the invention
The invention technical problem to be solved provides a kind of metallic fiber drawing mould universal adjustment device, realizes allowing the die hole serve as to lead to carry out drawing with trend naturally wiry, thereby guarantees the uniformity of wire product quality in batch production process.
For achieving the above object, following technical scheme is adopted in the invention:
Metallic fiber drawing mould universal adjustment device of the present utility model, comprise the spherical guide way that is arranged on mould seat top, be arranged on the locating piece of shell body intracavity bottom, described locating piece has ball recess, and the ball recess of described locating piece and spherical guide way form spherical pair; Wherein, pilot hole and die hole, locating piece perforate UNICOM and be located along the same line.
Be better implement the invention, circumferentially be embedded with permanent magnet on the changeover portion of described mould seat and spherical guide way.
Be better implement the invention, be arranged with inductive head and compensator corresponding to the permanent magnet place in the described shell body preset holes.
Be better implement the invention, be arranged with spring element on the described inductive head, the inductive head end of thread is rotary with the adjustment nut and is arranged in the shell body preset holes, and profiled sleeve and shell body preset holes screw the location and adjust nut.
Be better implement the invention, described compensator comprises fixed cover, push rod, and described fixed cover openend is provided with pipe joint corresponding to shell body preset holes bottom corresponding to fixed cover openend end face; Described push rod horizontal end spiral-lock is provided with valve block, clamping pad and oil sealing on the vertical bar of push rod successively in fixed cover.
Because adopt aforesaid technical scheme, the invention has following superiority:
1, because the microfilament drawing is different with common silk drawing process, during the microfilament drawing, die hole serves as that guiding is carried out drawing with trend naturally wiry, has guaranteed wire in drawing process, and the extruding force that the filament periphery is subjected to is equal, uniformly; The percentage elongation that has proved each position of wire is identical, thereby has guaranteed the uniformity of the whole pull strength of wire, has also guaranteed the uniformity of product quality in the batch production process.
2, during the metal wire drawing operation, wire passes through in die hole and in the pilot hole, under the tractive force effect of silk, mould and guide way is become one, the guide way sphere is the axle center with fixed body R simultaneously, mould is swung thereupon, and when oscillatory forces was not enough, inductive head was informed central control system with situation, by compensator required power is compensated, thereby make die hole adjust to concentric position by the trend naturally of silk, assurance die hole and silk are realized reasonable drawing on same ray.
3, the wire produced of above-mentioned drawing does not change the specific properties that raw material have; Be that product has not only reached international physical testing standard, also do not lose anti electromagnetic wave and function of shielding.
