Abstract
The utility model relates to a kind of spiral embossing blade.It is high that the spiral embossing blade that object is to provide has hardness, the simple feature of wear-resistant and structure.Technical scheme is: a kind of spiral embossing blade, and the center of its disc cutter hub is manufactured with the sword hole of a shaping embossing, and makes described sword hole be that shape of threads is arranged by the fluting running through sword hole and cutter hub outer; It is characterized in that: the hole wall in described sword hole is welded with tungsten steel blade.Described tungsten steel blade is formed by the little wolfram steel sheet of multiple arranged that joins end to end.
Description
Technical field
The utility model relates to RF and penetrates field of cables, specifically a kind of spiral embossing blade of rolling coaxial cable spirality outer conductor embossing.
Background technology
At present, the process of radio frequency coaxial-cable spiral outer conductor embossing is widely used in field of cables.Outer conductor embossing can improve the bending property of cable, facilitates installation.
Existing embossing cutter is generally common high-speed steel, but tool wear seriously can only use several hours, just needs to change cutter, not only have a strong impact on embossing cable product electric property, and cost is high.
Utility model content
The purpose of this utility model overcomes the deficiency in above-mentioned technical background, and provide a kind of novel spiral embossing blade, it is high that this spiral embossing blade has hardness, the simple feature of wear-resistant and structure.
For realizing above object, the utility model have employed following technical scheme:
A kind of spiral embossing blade, the center of its disc cutter hub is manufactured with the sword hole of a shaping embossing, and makes described sword hole be that shape of threads is arranged by the fluting running through sword hole and cutter hub outer; It is characterized in that: the hole wall in described sword hole is welded with tungsten steel blade.
Described tungsten steel blade is formed by the little wolfram steel sheet of multiple arranged that joins end to end.
The beneficial effects of the utility model are:
The utility model adopts the wolfram steel of high rigidity, high abrasion as cutter, not only significantly increase service life (improving more than 20 times), solve the difficult problem that existing cutter is easy to wear, also a saving cost (often need not change cutter), and the product electric property of producing is stablized, therefore the utility model can be widely used in the rolling of coaxial cable spirality outer conductor, has market prospects widely.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model.
Fig. 2 is left TV structure schematic diagram of the present utility model.
Fig. 3 is the A portion structure for amplifying schematic diagram in Fig. 1.
Fig. 4 is operation principle schematic diagram of the present utility model.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail.
As shown in Figure 1, a kind of spiral embossing blade, comprises disc cutter hub 5, through hole 4 used when being provided with fixing, and the size of described cutter hub is determined according to the object size of required processing.
The center of described disc cutter hub offers a sword hole 1, described disc cutter hub also offers a fluting communicated with described sword hole 3 (fluting runs through sword hole and cutter hub outer), such structure makes sword hole be shape of threads, can roll out spirality embossing on radio frequency coaxial-cable outer conductor.
Improvement of the present utility model on the hole wall in described sword hole, welds (brazing) have tungsten steel blade 2, and described tungsten steel blade is formed (as shown in Figure 3) by the little wolfram steel sheet 6 of multiple arranged that joins end to end; When embossing operation, by tungsten steel blade and the outer conductor extrusion friction processed, obviously, the polishing machine of embossing blade is significantly improved.
Operation principle of the present utility model is as shown in Figure 4: embossing blade rotates in (S direction) under device drives; With outer conductor 7 (A to) motion forward of the radio frequency coaxial-cable of inner wire and insulating barrier; After embossing blade, outer conductor surface has just rolled into spiral groove 7-1.
Claims (2)
