Description

[Detailed description of the invention] The present invention is a strainer pipe in which a large number of slits are formed in the peripheral wall of the pipe, and in particular, a strainer pipe made of synthetic resin such as vinyl chloride. Regarding the removal device.

This type of strainer pipe is inserted into a well, for example, and is used to prevent the intrusion of earth and sand and collect water. Since the material made of synthetic resin is soft, a continuous burr C remains which protrudes from the slit B of the strainer pipe A into the inside of the pipe, as shown in FIG.

Conventionally, in order to remove this burr C, a wire grinder was attached to the tip of the rotating shaft and fed into a fixed strainer pipe while rotating, but in this case, the wire of the wire grinder removed the soft burrs and the strainer pipe. The problem was that the strainer tube got stuck between the strainer tube and the inner wall of the wire grinder, preventing the wire grinder from rotating and deburring completely, and also causing the fixed strainer tube itself to rotate.

In particular, since the strainer pipe is long at 4m to 5m,
The rotating shaft also has a length corresponding to the length of the wire grinder, and since the shaft is supported only at the front, the wire grinder becomes unstable as it rotates. As a result, the wire grinder does not rotate smoothly, and the wire tends to get stuck between the burrs and the inner wall of the strainer tube, thereby exacerbating the above-mentioned drawbacks.

This invention eliminates the conventional drawbacks as mentioned above,
The idea was to provide a device that could reliably remove burrs from strainer pipes, and its gist was to attach a deburring wheel consisting of a grinder at the tip and a cutter with a slightly smaller diameter in front of the grinder. A rotary shaft is projected forward and supported by a main body that is movable back and forth, and the protruding part of the rotary shaft is surrounded and supported by a cylindrical tube with a bearing attached to the opening at its tip, and the outer periphery of the other end is fixed to the main body. The deburring device for a strainer tube is characterized in that the deburring wheel is rotated and fed into a fixed strainer tube to remove burrs from the inner surface of the tube.

Hereinafter, the present invention will be explained in detail based on the illustrated embodiment. In the figure, 1 is a main body, and wheels 2, 2 are attached to the lower surface of the main body, so that it can freely run back and forth on a rail 3 laid on the ground. It is configured.

A rotating shaft 4 is rotatably supported by a bearing 5.5 fixed on the upper surface of the main body 1. A pulley 6 is attached to the rear end of the rotating shaft 4, and a motor 7 built in the main body 1 is connected to the rotating shaft 4. Pulley 9 attached to output shaft 8
The motor 7 is
The main body 1 is configured to rotate as the main body 1 rotates, and most of the main body 1 projects forward.

11 is a grinder (wire grinder) attached to the tip of the rotating shaft 4; 12 is a cylindrical cutter with a slightly smaller diameter in front of the grinder 11; the grinder 11 and the cutter 12 constitute a deburring wheel 13; This deburring car 13
The burrs C and C inside the strainer pipe A are removed by rotating and moving the strainer forward.

In this case, first the burrs C and C are cut from the strainer tube A using the cutter 12 to remove the burrs for the first time, and then the cut surface is finished using the grinder 11. Even if you use burrs C and C, cutter 1
Since the wire is cut from the tube wall in advance at step 2, the wire will not get stuck between the burrs C and the inner wall of the strainer tube A.

Also, even if the deburring wheel 13 shakes as it rotates,
The cutter 12 plays a guiding role, and the deburring wheel 13 can rotate and move forward smoothly. Note that it is preferable to provide teeth on the front surface of the cutter 12 in order to cut the burr C reliably.

Reference numeral 14 denotes a cylindrical tube surrounding the protrusion of the rotary shaft 4, and bearings 17, 17 are attached to both open ends of the tube via flanges 16, 16.

Reference numeral 15 denotes a mounting plate, by which the outer periphery of one end of the cylindrical tube 14 is attached to the main body 1 and supported horizontally, and the other end of the cylindrical tube 14 extends to the vicinity of the deburring wheel 13. A rotating shaft 4 is supported here.

This reduces the deflection of the rotating shaft 4 and the vibration caused by the rotation of the deburring wheel 13, thereby ensuring smooth rotation of the rotating shaft 4. In addition, in the figure, 18 is a mounting table for mounting the strainer tube A, and 19 is a cylinder for fixing the strainer tube A placed on this mounting table 18.

Next, to explain an example of the use of the present invention, first, strainer pipe A after forming slits B,
is placed on the mounting table 18 and fixed by the cylinder 19.

By rotating the motor 7, the deburring wheel 13 is rotated via the rotary shaft 4, and the main body 1 is advanced along the rail 3, and while the deburring wheel 13 is being rotated, the strainer pipe is Immediately after the strainer tube A is fed into the strainer tube A and the burrs C and C are cut by the cutter 12, the cut surface is finished by the grinder 11 and the strainer tube A is deburred.

Since the present invention has the above-mentioned configuration, deburring of the strainer pipe A is performed by removing burrs C using the cutter 12.
The burr C is cut and immediately thereafter the burr cut surface is finished by the grinder 11, so that the burr C is reliably cut and removed and no burrs are left behind.

Moreover, since the burr C is cut in advance, it is also possible to use a wire grinder as the grinder 11, and even in this case, its rotation is not hindered.

Furthermore, even if the deburring wheel 13 shakes as it rotates, the rotating shaft 4 is rotatably supported by the other end of the cylindrical tube 14 whose outer periphery is fixed to the main body. 13 can be smoothly rotated and advanced, and therefore the inside of the strainer pipe A can be reliably deburred.
