Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of a cable end member fixed to the end of an inner cable of a control cable used for remote control in various industrial equipment such as automobiles. More specifically, the present invention relates to an improvement in a cable end member formed and fixed to the end of an inner cable of a control cable by die-casting.

[Prior Art] Conventionally, as a cylindrical cable end member formed by die-casting, an extremely simple cylindrical cable end member as shown in FIG. 7, for example, has been adopted.

[Problems to be solved by the invention] In cable end members such as those mentioned above, after die-cast molding, it is common for "burrs" to be attached to the joints of the mold, that is, the parting line, and it is necessary to remove them. be. For this purpose, the "burr" is removed by a press or the like using a cutting die through which the cable end member can pass in the lateral direction. However, in this work, as shown in Figure 3,
"Burrs" 2, 2 of the cable end member 1 against the cutting die 11
A is placed on the cable end member, and the push rod 12 is used to press the cable end member in the direction of A to create a "burr".
2, 2a will be removed. In this case, for example, as shown in Fig. 4, if only one "burr" 2a is removed first, the cable end member 1 will rotate in the direction B and the "burr" 2 will remain, which may not be completely removed. be. The cable end member with “burrs” left behind is
There are problems such as problems such as interfering with the mating metal fittings, making it difficult to install, and injuring the hands of the installation worker due to ``burrs''. In order to eliminate these problems, it is inconvenient that the remaining "burrs" must be removed one by one with a chisel or the like.

[Means for Solving the Problem] The end member of the control cable of the present invention is formed by die-cast molding, and the cable end member has a substantially cylindrical shape. A structure is adopted in which a guide surface is provided with a plane cut out perpendicularly to the parting line.

[Function] The terminal member of the control cable of the present invention (hereinafter simply referred to as cable) has a guide surface cut out perpendicularly to the parting line in one area of the tip, and the parting line of the terminal member The cutting die for removing "burrs" formed along the edges is provided with a guide groove through which only the guide surface can pass, and by passing along the guide groove, the terminal member is prevented from rotating. No burrs left behind.

[Example] Next, an example of the present invention will be described with reference to the drawings.

Fig. 1 is a perspective view showing one embodiment of the cable end member of the present invention, and Fig. 2 shows the state in which ``burr'' remains on the parting line after die-casting of the cable end member, and the process to remove the ``burr''. A perspective view showing the cutting die, Figures 5 and 6 are for the "burr" of the cable end member.
It is an explanatory view showing a process of removing.

In FIG. 1, a cylindrical cable end member 20 is provided with a guide surface 21 in a region of the end thereof, which is a plane cut out in a direction perpendicular to a parting line 23. As shown in FIG. In the terminal member 20 having such a structure, as shown in FIG. 2, "burrs" 23 are attached to the parting line, which is a joint between the molds, when die-casting is performed.
In order to remove this "burr", it is removed using a cutting die, but in the shape of the cable end member of the present invention, the guide surface 21 is removed using a cutting die 30 as shown in FIG.
It has a shape that has a guide groove 31 through which it can pass. To remove the "burrs" using this cutting die, place the terminal member 20 on the cutting die 30, fit the guide surface 21 into the cutting die along the guide groove 31, and the "burrs" 22, 22a will be removed. It stops on the surface of the cutting die. When the push rod 31 is pressed in the A direction by a press machine or the like, the guide surface 21 of the cable end member 20 rotates in the A direction along the guide groove 31 of the cutting die 30, as shown in FIG. Since the "burrs" 22, 22a can be completely removed, the "burrs" 22, 22a can be completely removed.

[Effect of the invention] The cable terminal member according to the shape of the invention has the following characteristics:
Since there is no rotation when removing the "burr," the "burr" can be completely removed, there is no need for any rework, and as a result, the engagement work of the end members can be performed extremely smoothly. It can produce excellent effects.

[Brief explanation of drawings]

Fig. 1 is a perspective view showing a cable end member according to an embodiment of the present invention, and Fig. 2 shows a cable end member with ``burr'' still attached to the parting line after die-casting, and ``burr'' removed. FIGS. 3 and 4 are explanatory diagrams showing a state in which burrs are removed from a conventional cable end member, and FIGS. 5 and 6 are illustrations of a cable end member of the present invention. FIG. 7 is an explanatory view showing a state in which "burrs" are removed, and FIG. 7 is a perspective view showing the shape of a conventional cylindrical cable end member. 20...
