Detailed Description
The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings, but the scope of the present invention is not limited to the following.
Examples
As shown in fig. 1, 2 and 3, a novel outer conductor embossing mold for an ultra-soft 1/2 ″ feeder cable comprises an embossing head 1 rotating concentrically, wherein an embossing ring 2 is arranged in the embossing head 1, a center line 4 of the embossing ring is not the same line as a center line 5 of the embossing head, and the center line 5 of the embossing head coincides with a center line of an outer conductor of the cable. Compare promptly in prior art, the ring of embossing and the concentric setting of embossing head, the eccentric settings of embossing in this embodiment, the trough that can realize the embossing is adjustable, adjust embossing ring 2 and novel outer conductor eccentricity promptly, simultaneously, the pitch of embossing also can be adjusted in this embodiment, realize the regulation of embossing pitch promptly through debugging embossing multiplying power, the embossing multiplying power is the ratio of the rotational speed of novel outer conductor production speed and embossing ring, the unchangeable condition of novel outer conductor production speed improves or reduces the rotational speed of embossing head, just can realize reducing or increasing of embossing pitch. The electric performance of the product is greatly influenced by the size of the outer conductor of the cable, the best and most stable size of the outer conductor with the electric performance can be found by adjusting the wave troughs and the pitches of the fixed eccentric embossing, and the qualified rate of the electric performance of the product is finally improved.
Further, in the present embodiment, the inner hole edge 21 of the embossing ring 2 is perpendicular to the center line of the embossing ring 2. Be that inner hole sword 21 is 90 degrees settings with 2 central lines of embossing ring, also when the line is embossed to the cable outer conductor, inner hole sword 21 is 90 degrees with the cable outer conductor, compare among the prior art, the irregular setting of embossing ring 2, the hole blade is total about 340, make the hole blade rub out the line from the embossing ring import from beginning always during the embossing, resistance during the embossing is great, it is all very high to the soft or hard and thickness requirement of copper pipe, and this embodiment is when the embossing, and is littleer with the wear of novel outer conductor. Meanwhile, the contact surface of the embossing cutting edge is small during embossing in the embodiment, embossing resistance is much smaller than that of the embossing in the prior art, regular lines can be smoothly embossed when the copper pipe is a little thicker or harder or the copper pipe is a little thinner or softer, and the embossing is easy to form.
Furthermore, the embossing ring 2 is connected with the embossing head 1 through a moving rod 3, and the moving rod 3 enables the embossing ring 2 to move up and down in the embossing head 1. This carriage release lever 3 can realize that embossing ring 2 reciprocates in embossing head 1 is inside for the relative position of the central line of embossing ring 2 and the central line of cable outer conductor is adjustable, and this embodiment promptly can adjust embossing ring 2 and novel outer conductor eccentricity at any time according to the actual production demand, realizes the trough adjustment of embossing.
In particular, the embossing rings 2 are concentric rings. The embossing ring in the prior art is also selected to be a concentric ring and arranged concentrically with the cable outer conductor, but in the embodiment, the difference is that the embossing ring 2 is arranged eccentrically with the cable outer conductor. The concentric rings also facilitate the machining of the embossing rings.
A novel method for embossing an outer conductor of an ultra-flexible 1/2' feeder cable comprises the following steps:
s1, polishing the embossing ring 2 into a regular annular mold; namely, the inner hole blade 21 of the embossing ring 2 is 90 degrees when contacting with the outer conductor of the cable, and the embossing resistance is reduced.
S2, installing the milled embossing ring 2 in the step S1 in an embossing head 1, wherein the embossing ring 2 can freely move in the embossing head 1; therefore, the center lines of the embossing ring 2 and the cable outer conductor are not on the same center line, and the eccentricity of the embossing ring 2 and the cable outer conductor can be adjusted in real time. Before this step, it is generally necessary to adjust the position of the embossing ring 2 according to the set eccentricity, so as to achieve the embossing depth required by the process.
S3, introducing the novel outer conductor of the super-soft 1/2' feeder cable into the embossing ring 2 to finish embossing. Before letting in super gentle 1/2 "feeder cable's novel outer conductor into embossing ring 2, need carry out the speed governing to embossing head 1, then readjust super gentle 1/2" feeder cable's novel outer conductor admission speed to it is adjustable to realize the product embossing pitch.
Specifically, in S2, the embossing ring 2 moves up and down in the embossing head 1. Namely, the center line of the embossing ring 2 moves up and down in the plane of the embossing head 1, so that the eccentricity difference with the cable outer conductor is realized.
Furthermore, when the size of the corrugation trough is adjusted by adjusting the eccentricity of the corrugation ring, when the corrugation ring is abraded to a certain angle and is abraded to a larger extent, the corrugation ring can be rotated by 120 degrees, corrugation is continued, and after the corrugation ring is rotated three times, the corrugation ring 2 can be directly replaced. A more permanent use of the embossing ring 2 is achieved.
