Problems solved by technology

[0002] In the field of fireproof cables, the cable includes a metal sheath layer with armor and a fireproof filler filled between the cable cores. During processing, a circular metal sheath is welded after the metal sheath armor and powder filling process. Then fill the fireproof powder filler to form an armored cable with a metal sheath layer. Because the cable core is arranged as twisted, the filled fireproof powder filler cannot close the gap in the cable core without the action of external force. The filling is uniform, an

Embodiment 1

[0020] refer to figure 1 The armored cable 100 full circle equipment provided in this embodiment is a vertical structure, which is installed on the production line of the armored cable 100, after a metal sheath armoring and powder filling process, and the cable passes through the metal sheath. The armoring and powder filling process welds a circular metal sheath and fills a fireproof powder filler, then processes it into an armored cable 100, and then enters the round device of the armored cable 100, wherein the entire armored cable 100 The circular equipment includes: a frame, a predetermined number of full-circle mechanisms 6 and a vibration mechanism.

[0021] refer to Figure 5 , at the same time, the present embodiment provides a deceleration commutator 62 for the armored cable 100 full circle equipment, which includes a deceleration commutator input shaft 622 and a deceleration commutator input shaft 622 is provided with a For the output shaft 620 of the deceleration c...

Embodiment 2

[0028] refer to figure 2 , image 3 as well as Figure 4 , this embodiment 2 has been improved on the basis of the scheme of embodiment 1, and the unimproved parts are consistent with embodiment 1, and its improvement scheme: the support angle frame 2 includes three support plates, and the three support plates They are respectively the first support plate 20, the second support plate 21 and the third support plate 22. The first support plate 20, the second support plate 21 and the third support plate 22 are connected in turn to form the In the full-circle space 200, the included angle between two adjacent support plates is 108° or 120°, and the full-circle mechanisms 6 are installed on three support plates respectively, and are arranged alternately with each other.

Abstract

The invention provides armored cable rounding equipment. The equipment comprises a rack, a preset number of rounding mechanisms and a vibration mechanism; a vibration head in the vibration mechanism vibrates and knocks an armored cable located above a cable inlet, so that a fireproof powder filler vibrates uniformly and fills more tightly and compactly; two rounding cylinders in a preset number ofrounding mechanisms arranged on a supporting corner bracket in a staggered mode achieve enclasping and clamping of the armored cable; each rounding cylinder is provided with an arc-shaped groove matched with the outer diameter of the armored cable in the circumferential direction of the rounding cylinder; rounding is conducted on the armored cable through relative rotation of the two rounding cylinders; and traction of the armored cable is realized, the filling uniformity and compactness of the fireproof powder filler in the armored cable are improved, the fireproof performance is improved, the roundness of the armored cable is improved, the tensile strength and the compression resistance of each part of the armored cable are further improved, and the armored cable is safer to use.

Description

technical field [0001] The invention relates to the field of equipment for cable production, in particular to an armored cable rounding equipment. Background technique [0002] In the field of fireproof cables, the cable includes a metal sheath layer with armor and a fireproof filler filled between the cable cores. During processing, a circular metal sheath is welded after the metal sheath armor and powder filling process. Then fill the fireproof powder filler to form an armored cable with a metal sheath layer. Because the cable core is arranged as twisted, the filled fireproof powder filler cannot close the gap in the cable core without the action of external force. The filling is uniform, and there are some dead corners that are not filled, which will lead to a decrease in the fire resistance of the cable. The armored cable after forming has problems such as uneven and loose filling of the fire protection powder, and its cross section is not round enough. The tensile and ...
