Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an apparatus for compression molding a linear conductor, and more specifically, a pair of rolls for compressing a linear conductor are arranged vertically. The present invention relates to a linear conductor compression device having a structure in which each of the forming rolls is rotatably loaded with its own shaft being pivotally supported on upper and lower bearing frames provided on the device main body side.

[Problems that conventional technologies and ideas try to solve]

Conventionally, in a linear conductor compression device in which forming rolls are arranged in pairs in the vertical direction, in the case of a lower roll position fixed type, the lower roll is inserted and removed from above, but in reality When replacing the roll during work, the wire conductor remains passed through the wire passing shaft of the compression device, so
It is difficult to attach and detach the roll from above, and to solve this problem, we created a way to release the wire conductor from above the roll so that the wire conductor passing over the roll can be loosened and the roll can be attached and detached. Work had to be done.

Further, as shown in FIG. 1, the upper and lower roll bearing frames 5, 5' are pivoted to the main body 4 of the apparatus by a pivot 9 so that the frames 5, 5' can be rotated to open and close in the vertical direction. , the shafts 2a and 3a of the rolls are connected to the bearing frames 5 and 5'.
It has been proposed to fit into a groove formed in the opposing part of the . (Refer to Japanese Utility Model Publication No. 59-26819.) In this type, the bearing frames 5, 5' themselves are rotated when replacing the rolls, so the movement space of the movable parts tends to become large, and the surrounding space When there was no margin, workability deteriorated. In addition, especially when attaching and detaching the lower roll 3, it is necessary to lower and open the bearing frame 5 to a position where it does not come into contact with the linear conductor 1 passing through it, but this increases the space under the lower bearing frame 5. However, there was a problem in that it was easy to increase the size of the device.

The present invention was developed based on the above-mentioned problems of the conventional technology, and allows the roll that forms the lower side of the linear conductor to be attached and detached without involving large moving parts, making it possible to greatly contribute to compactness. It is an object of the present invention to provide this kind of linear conductor compression device.

[Means to solve the problem]

The linear conductor compression device provided by the present invention, as shown in FIGS. 2 to 5 of the accompanying drawings,
A bearing frame 5 provided for the lower roll 3 has an opening 7 through which the roll 3 can pass laterally at the other end of the shaft 3a that faces a side wall 5b that pivotally supports one end of the shaft 3a of the roll 3. A frame body 5a having
and a bearing groove 6b that opens at the upper end at approximately the center of the inner surface.
a bearing member 6 having a step portion 6a on its lower portion that can be engaged with the opening edge of the frame body 5a; and a pivot bolt 8 that passes through the side end of the bearing member 6 and screws into the side wall of the frame body 5a with the other end of the shaft 3a of the roll 3 fitted into the bearing groove 6b. It is characterized by being composed of.

〔Example〕

Below, Figures 2 to 5 show an embodiment of the present invention.
This will be explained using figures.

In this embodiment, the bearing frame 5 is a fixed frame in which the base 4 of the frame body 5a is integrated with the apparatus body (stand).

Thus, the frame main body 5a has a box shape with an inner diameter larger than the outer diameter of the roll 3 and a substantially semicircular housing portion, and a bearing groove 5b in which one end of the roll shaft 3a is fitted in one side wall 5b. ₁ , and on the other side corresponding to the side wall 5b, an aperture 7 with a border matching the semicircular inner surface is formed.

On the other hand, the bearing member 6 has a bearing groove 6b whose upper end is open at a substantially central portion of the inner surface, a substantially arc-shaped lower edge, and a hook-shaped step portion 6a at the inner edge of the portion. Further, an extension portion 6c with a through hole is formed at the side end.

The bearing member 6 shaped as described above has a stepped portion 6a on its lower inner edge that is engaged with the edge of the opening 7 of the frame body 5a, and a side end 6c that is attached to the base side surface of the frame body 5a. and the side edge 6c
By screwing the bolt 8 that passes through the frame body 5a into the side wall of the frame body 5a and tightening it, the stepped portion 6a is assembled to the frame body 5a while maintaining the locked state, and the opening 7 is closed.

The roll 3 has one end of the shaft 3a fitted into a bearing groove _5'b1 in the side wall 5b of the frame body 5a, and
The other end of the shaft 3a is fitted into the bearing groove 6b of the bearing member 6, and the roll 3 is rotatably supported in a floating state within the frame body 5a.

[Effect]

By being configured as described above, the lower roll 3 has the bearing member 6 supported by the bolt 8 that pivots the bearing member 6.
By loosening the bearing member 6, the frame body 5a
The step part 6a is removed from the opening 7 of the frame body _5a , and one end of the roll shaft 3a is removed from the bearing groove 6b. By tilting it to the side and slightly downward, it is possible to release the half-fitted state with the linear conductor 1 passing upward, and then tilt the bearing member 6 in the disengaged state downward using the bolt 8 as a fulcrum. (See arrow x ₂ ) At least remove it from opening 7,
The roll 3 can then be removed from the opening 7 thus opened. It will be readily understood that when loading a roll, the steps described above may be reversed.

As described above, by making only some of the bearing members 6 of the bearing frame 5 movable parts, the space below the bearing frame 5, that is, the space in which the members 6 are allowed to move, can be made smaller.

[Application example]

In the embodiment described above, the bolt 8 as a pivot that penetrates the side end 6c of the bearing member and is screwed into the frame body 5a is tightened to press the side end 6c to the side wall of the frame body 5a. However, the invention is not limited thereto, and for example, an elastic body such as a coil spring may be inserted into the bolt 8, and the side end 6c may be tightened via this elastic body. In that case, it is possible to detach and rotate the bearing member 6 from the frame body 5a by deforming the elastic body, and the bolt 8
There is no need to loosen them one by one.

Furthermore, in the above-described embodiment, the bearing frame 5 (frame body 5a) is of a fixed (non-rotating) type, but it is not limited thereto, and can also be applied to a rotating type as shown in FIG. be. In that case, the rotating bearing frame shall utilize the rotation of the entire frame when major repairs are required, and when attaching or detaching the roll, it will be handled by detaching and rotating the bearing member. You can do it like this.

[Effect of idea]

As explained above, according to the linear conductor compression device of the present invention, it is possible to attach and detach the lower roll of the linear conductor from the side of the bearing frame without making any changes to the conductor. In addition, the intended purpose of providing a device that allows the roll that forms the lower side of the wire conductor to be attached and detached without involving large moving parts, and that can greatly contribute to compactness, has been achieved. , is of great practical benefit.
