Description

The metal knitted burr of cable shield layer cancellation element

Technical field

The utility model relates to a kind of production equipment with the woven shield cable, the device that the braid burr is eliminated when particularly relating to metal knitted screen cable cover(ing) extrusion.

Background technology

In the communication cable of producing at present, the method that the shielding mode employing metal wire knitted shielding of the cable that requirement on electric performance is much arranged is arranged, in the braiding production process because the wire wiring amount of the spindle of braiding machine is limited, the length of the wire bar cable that the client needs is longer again, the mode of connection of often taking to change ingot in the production satisfies client's fixed length requirement, in process of production, sometimes the situation that braided metal monofilament broken string also occurs, being operating as after above two kinds of situations appears: directly pull out wire under the eye mould among the From, press the braiding machine inching button again, make the wire splice on braid, and pruned the end of a thread, the assurance outward appearance is level and smooth. but often in the pruning process of the end of a thread, can't prune smoothly fully by Bao Certificate the end of a thread, or the end of a thread of fixing at wire rod around to the take-up axle, because bending wire, the perk again of the end of a thread of fixing, cause after next procedure sheath Ya Chu Time Chu Now prunes owing to braiding burr not Enough smoothly cause jagged place sheath Chu Now Needles eyelet or broken Pi Qing Condition, the bad problem that causes spark-over, after the sheath Chu Now spark-over, wire rod will be cut off, make the part wire rod decide Long owing to can not satisfy the requirement of deciding Long in objective family can not shipment, cause bigger scrapping.

Summary of the invention

For overcoming the deficiency of above-mentioned background technology, make cable just can eliminate the end of a thread burr that wire sheathing occurs in process of production simultaneously, designing a kind of metal knitted burr of cable shield layer cancellation element is the purpose of this utility model place.The technical solution of the utility model is by utilizing the PU bar to be installed on a kind of special device, utilize the anti-wear performance of PU material, rub the burr after the braiding pruning smoother, send under escort cover again, thereby avoided owing to the burr that braid is pruned the end of a thread place is propped the sheath that pierces through wire rod or caused sheath at the thickness at burr place Enough not, to such an extent as to when making capable sparking test in the back, above problem Chu Chu Now spark-over causes wire rod to cut off.The technical solution of the utility model is a kind of metal knitted burr of cable shield layer cancellation element that is used for before the cable cover(ing) extrusion operation that comes specific implementation by following technical measures, it is characterized in that it is by hold-doun nut 1, back noseplate 2, solid PU bar 3, preceding noseplate 4, Go-over mould 5, bracing frame 6 is formed, wherein: Go-over mould 5 is to make with stainless steel material, the aperture of mould can directly be come to determine according to the line of braiding heart yearn, on noseplate 4 centre bores, preceding noseplate 4 was the big circular holes in a centre before this Go-over mould 5 was mounted in, circumferentially clocklike gather many separated times hole disk and be fixedly mounted on an end of bracing frame 6; Back noseplate 2 is the disks that axle journal is arranged, and disc centre has through hole, circumferential many separated times hole of clocklike gathering, and threaded back, axle journal end noseplate 2 screws an other end that is installed in bracing frame 6 by the cooperation of nut 1.Back noseplate 2 is identical with the disk diameter of preceding noseplate 4, separated time hole count, the aperture on the disk and the pattern of arranging also are consistent, adopt the PU material through the whole rectangular solid PU bar 3 that extruder is processed into wear symmetrically back and forth full after whole separated time holes on the disk of noseplate 2 and preceding noseplate 4; Back noseplate 2 and preceding noseplate 4 and bracing frame 6 are to be processed into sheet metal,

The utility model Gong Zuo Time, the braiding heart yearn enters from Go-over mould 5, center through preceding noseplate 4, the center of the solid PU bar 3 that gathers is passed through, center guide hole from back noseplate 2 goes out again, weave heart yearn then and advance sheath extrusion head, want first loosen nut 1 before this, the preceding relatively noseplate 4 of back noseplate 2 rotates a certain angle, allow densely covered solid PU bar 3 reverse, wrap surface at the braiding heart yearn, again hold-doun nut 1 is tightened, traction by extruder during extrusion, braid on the braiding heart yearn rubs in the solid PU bar of wrapping 3, and the wire burr after braiding is pruned can tiltedly wrap, have under the friction of PU bar of certain degree of hardness to seem smoother, eliminated burr.

After good effect of the present utility model is to have used this device, because of the wire burr of braiding after pruning not Enough smoothly cause the problem of jagged place sheath spark-over can Da Fu Minus few, especially for the extrusion of thin insulating sheath, originally spark-over is more serious, can't satisfy the requirement of client's fixed length, use this device back thin insulating sheath spark-over situation less, this device is applicable to all metal wire knitted wire rod sheath extrusions.And it is simple in structure, easy for installation, reliable and stable.
