Description
Technical Field
The invention relates to the technical field of cable stripping, in particular to a processing machine for double-head coaxial lines.
Background
Currently, the coaxial line on the market is generally of a four-layer structure, as shown in fig. 1, and when the coaxial line is processed, three outer layers need to be stripped, and the stripped lengths of each layer are different, as shown in fig. 2. When the coaxial line is stripped, a stripping mechanism is adopted to strip the coaxial line for three times at present, and the processing efficiency is low. When two ends of the coaxial line need to be stripped, three layers of one end need to be stripped firstly, then the coaxial line is turned, and three layers of the other end need to be stripped. That is, the existing wire stripping mechanism cannot strip one end of the coaxial wire at the same time, and cannot strip the other end of the other coaxial wire at the same time, so that the machining efficiency is low.
Moreover, the existing coaxial wire stripping machine generally comprises a wire stripping mechanism and a wire feeding mechanism, wherein the wire feeding mechanism is used for feeding the coaxial wire to the wire stripping mechanism for stripping, and because the coaxial wire is not rigid, the wire feeding mechanism cannot enable the central line of the coaxial wire to coincide with the central line of a hole formed by surrounding each blade in the wire stripping mechanism during wire feeding. In addition, the cutter head of the wire stripping mechanism generally adopts a mode of opening and closing left and right or up and down by two blades to cut, and the wire stripping mechanism mainly has the following defects: firstly, when two blades are positioned, the two blades cannot be exactly opposite to each other, and when a coaxial line is cut, sliding deviation is easy to generate, so that inaccurate positioning is caused; secondly, when two blades are adopted for cutting, the inner layer or the shielding layer of the coaxial line is easily pulled due to inaccurate positioning; thirdly, the cutting angle of the blade of the wire stripping mechanism is not perpendicular to the wire axis, and the defect in cutting precision or the complexity of control are easily caused.
