Abstract
The invention relates to a mold adjustment method of processing a cable and a used processing device. A mold adjustment method of a multilayer extrusion crosshead comprises the following steps: firstly, placing a mold adjustment assist device (2) into the multilayer extrusion crosshead (1); extruding a pipe and adjusting a mold as well as taking out the mold adjustment assist device (2) after the mold meets the concentricity requirement; penetrating a cable conductor into a mold core of the multilayer extrusion crosshead (1) directly, and normally starting the device to produce. The mold adjustment assist device (2) is composed of a tapered body (3), a barrel (4) and a hollow cylinder (5), wherein the outer surface of the hollow cylinder (5) is provided with the tapered body (3), the back end of the tapered body (3) is connected with the barrel (4), the barrel (4) is in threaded connection with the hollow cylinder (5), and the barrel (4) is in threaded connection with the back end of an internal mold guide tube (6). According to the invention, the problems that multiple cable conductors are wasted in the existing method of processing the cable when the mold is adjusted, the consumed time is long, the working efficiency is low, and the manufacturing process is complicated are solved.
Description
Technical field
The present invention relates to the method for adjusting mould of cable processing and used technological equipment.
Background technology
Having now in cable processing, is earlier conductor to be passed interior nib during the multi-layer co-extruded head mode transfer of use, while the mode transfer of starting shooting, treat that mode transfer meets the requirements of concentricity after, normal boot-strap production again.This method is wasted a lot of cable conductors, and consuming time longer, inefficiency, complex manufacturing technology.
Summary of the invention
The purpose of this invention is to provide a kind of multi-layer co-extruded head method for adjusting mould and used mode transfer assistor, the invention solves existing cable processing method and when mode transfer, waste a lot of cable conductors, and consuming time longer, inefficiency, the problem of complex manufacturing technology.
Multi-layer co-extruded head method for adjusting mould; At first pack into the leading portion hollow cylinder 5 of multi-layer co-extruded head 1 mode transfer assistor 2 of the hollow cylinder 5 of mode transfer assistor 2 is passed the interior die orifice of multi-layer co-extruded head 1; The cylinder 4 that the rear end then is threaded through hollow cylinder 5 is connected in the deutostoma end of mozzle 6; Less than below the 0.1MM, cone body 3 taperings on the mode transfer assistor 2 and the internal mold internal taper of multi-layer co-extruded head 1 match its leading portion hollow cylinder 5 external diameters of mode transfer assistor 2 than multi-layer co-extruded head 1 internal mold bore; Squeeze the pipe mode transfer again, wait the mould concentricity to reach requirement after, take out mode transfer assistor 2, directly cable conductor is passed the core rod of multi-layer co-extruded head 1, just normally starting device production afterwards.
The mode transfer assistor that multi-layer co-extruded head method for adjusting mould is used; Described mode transfer assistor 2 is made up of cone body 3, cylinder 4, hollow cylinder 5; Hollow cylinder 5 outer surfaces have cone body 3; Be connected with cylinder 4 in the rear end of cone body 3; Cylinder 4 is threaded with hollow cylinder 5, and cylinder 4 is threaded with internal mold mozzle 6 rear ends.
Multi-layer co-extruded head method for adjusting mould of the present invention and used mode transfer assistor; In the method; Because leading portion hollow cylinder 5 external diameters of mode transfer assistor 2 are slightly littler than multi-layer co-extruded head 1 internal mold bore; Cone body 3 taperings on the mode transfer assistor 2 and the internal mold internal taper of multi-layer co-extruded head 1 match; Add the rear end and be fixed on mozzle 6 centers through cylinder 4; Mode transfer plays the effect of a sight alignment, so that more can reach concentricity.Principle of the present invention is promptly utilized the mode transfer assistor to extend internal mold to outer die orifice and is squeezed the pipe mode transfer again, treat that the mould concentricity reaches requirement after, take out the mode transfer assistor, get final product normal boot-strap production.This invention has does not waste cable conductor, cost-effective advantage.The present invention has improved the mode transfer efficient of cable conductor processing.

Symbol description among the figure: multi-layer co-extruded head 1, mode transfer assistor 2, cone body 3, cylinder 4, hollow cylinder 5, mozzle 6.
Embodiment
Below in conjunction with accompanying drawing and with illustrated embodiments the present invention is done detailed explanation.
Consult Fig. 1; Multi-layer co-extruded head method for adjusting mould; At first the hollow cylinder 5 of the mode transfer assistor 2 multi-layer co-extruded head 1 of packing into; Its leading portion hollow cylinder 5 of mode transfer assistor 2 passes the interior die orifice of multi-layer co-extruded head 1; The cylinder 4 that the rear end then is threaded through hollow cylinder 5 is connected in the deutostoma end of mozzle; Less than below the 0.1MM, cone body 3 taperings on the mode transfer assistor 2 and the internal mold internal taper of multi-layer co-extruded head 1 match leading portion hollow cylinder 5 external diameters of mode transfer assistor 2 than multi-layer co-extruded head 1 internal mold bore; Squeeze the pipe mode transfer again, wait the mould concentricity to reach requirement after, take out mode transfer assistor 2, directly cable conductor is passed the core rod of multi-layer co-extruded head 1, just normally starting device production afterwards.
The mode transfer assistor that multi-layer co-extruded head method for adjusting mould is used; Described mode transfer assistor 2 is made up of cone body 3, cylinder 4, hollow cylinder 5; Hollow cylinder 5 outer surfaces have cone body 3; Be connected with cylinder 4 in the rear end of cone body 3; Cylinder 4 is threaded with hollow cylinder 5, and cylinder 4 is threaded with internal mold mozzle 6 internal orifice rear ends.
The present invention is earlier mode transfer assistor loading unit, squeezes the pipe mode transfer again, wait the mould concentricity to reach requirement after, the taking-up assistor directly passes core rod to cable conductor, afterwards just normally starting device production.
Above embodiment is more preferably embodiment a kind of of the present invention, and common variation that those skilled in the art carry out in present technique scheme scope and replacement should be included in protection scope of the present invention.
