A kind of stranding machine outlet pressing mold
Technical field
The utility model relates to a kind of production mould of electric wire, particularly a kind of stranding machine outlet pressing mold.
Background technology
Need to use drawing machine that copper core is carried out the stretching process of drawing-down in the production process of electric wire.But the drawing machine used at present is when the thin copper core that process diameter is less, and rocking of copper core is more severe, easily occurs the phenomenon broken by copper core, causes waste, increases production cost but also affects product quality and production efficiency.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of stranding machine outlet pressing mold, and this pressing mold can avoid the rocking of copper core, reduce the phenomenon that to break appear in copper core, thus overcomes above-mentioned the deficiencies in the prior art.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of stranding machine outlet pressing mold, its formation comprises upper bolster, die shoe, and the binding face of described upper bolster and die shoe has pressuring line groove, and be respectively equipped with groove at the leading-out terminal of upper bolster and die shoe, pressuring line groove is communicated with groove; In a groove rolling wheel is housed, has through wires hole in the central authorities of rolling wheel.
In above-mentioned stranding machine outlet pressing mold, preferably, described rolling wheel is cylindrical.
The beneficial effects of the utility model: compared with prior art, the utility model installs rolling wheel additional in traditional outlet pressing mold, by rolling wheel, support and spacing is carried out to copper core, effectively prevent copper core rocking in process of production, significantly decrease the phenomenon that copper core is pulled off, avoid waste, save production cost, improve production efficiency, ensure that product quality, the copper core effect thinner to diameter is especially remarkable.

Fig. 2 is structure of upper die base schematic diagram of the present utility model;
Fig. 3 is rolling wheel structural representation of the present utility model.
Below in conjunction with the drawings and specific embodiments, the utility model is further described.
Embodiment
Embodiment 1.As shown in Figure 1, 2, comprise upper bolster 1, die shoe 2, the binding face of upper bolster 1 and die shoe 2 has a pressuring line groove 3, upper bolster 1 is symmetrical with the structure of die shoe 2, its structure as shown in Figure 2, be respectively equipped with groove 4 at the leading-out terminal of upper bolster 1 and die shoe 2, pressuring line groove 3 is communicated with groove 4; A columniform rolling wheel 5 is housed in groove 4, and as shown in Figure 3, have a through wires hole 6 in the central authorities of rolling wheel 5, the aperture of through wires hole 6 is consistent with the diameter of wire of dimension for the structure of rolling wheel 5.During use, select corresponding rolling wheel 5 according to the specification of electric wire, the aperture of its through wires hole 6 and the diameter of electric wire are matched, then rolling wheel 5 is loaded in groove 4, then upper bolster 1 and die shoe 2 are fit together be arranged on drawing machine.
Execution mode of the present utility model is not limited to above-described embodiment, and the various changes made under the prerequisite not departing from the utility model aim all belong within protection range of the present utility model.
