Description

{A grinding device of automatic burr in pipe}

The present invention relates to a pipe automatic chamfering device that can automatically and easily and easily remove the burrs formed on the cutting surface of the pipe during the cutting process of the pipe used for laundry drying racks or hangers, in particular On the rear of the inclined pipe supply unit in which a plurality of cutting pipes are stacked in the center of a table of a chamfering machine, a pipe is placed one by one, and a partition unit is installed so as to supply the pipe. An inclined pipe aligning unit arranged to be connected is installed, and a cylindrical pipe extracting cam that is supported and fixed to a shaft through a driving motor is rotated at the rear of the pipe alignment unit, and a guide bar is provided on the upper side of the pipe extracting cam. The cylinders are lifted up and down by absorbing both ends of the pipe The extended vacuum suction tube is installed through a vacuum cylinder, and the upper side of the pipe extraction cam is sucked through the vacuum suction tube so that both sides of the slightly elevated pipe are chamfered so that the motor and the spindle can rotate respectively. Since the feed cylinders are connected to both sides of the spindles so that the spindles are rotated before and after the motors are rotated, the pipes used for laundry drying racks or hangers are cut to a predetermined length, and then the cut pipes are inclined. A plurality of pipes are stored in the pipe feeder and are uniformly arranged one by one through the inclined pipe alignment unit, and the aligned pipes are automatically withdrawn one by one through a cylindrical pipe take-out cam to transfer the motor and spindle After the cutting process, burrs on both sides of the pipe are Automatic pipe chamfering device which can be easily and easily removed automatically, and further improves the chamfering work efficiency of the cutting pipe, and completely prevents the safety accidents of workers generated during chamfering of the pipe. It is about.

Generally, pipes used for laundry drying racks or hangers, etc., are cut to a certain length, and burrs are formed on both sides of the pipe after cutting, and such burrs may cause poor assembly with other pipes. By doing so, the burrs formed on both cutting surfaces after the pipe cutting process are removed by using a burr removing tip mounted on a grinder or a rotating spindle.

At this time, the burr removing spindle of the pipe is mounted on a chuck of a small lathe, and while rotating it, the burr removing tip mounted on the spindle is alternately mounted at both ends by hand while holding the cut pipe by hand. ) To remove the burr.

However, in the case of the burr removing operation of the conventional cutting pipe as described above, by directly holding the pipe in contact with the burr removing tip of the spindle rotating at high speed, workability and productivity due to the burr removing operation are extremely reduced. Of course, there is a big disadvantage that the burrs formed on both sides of the pipe can not be chamfered properly.

In particular, when the pipe is in contact with the burr removal tip of the spindle rotating at high speed, the hand of the human body is in contact with the spindle, there are many problems such as frequent accidents occur.

The present invention has been made in order to improve the conventional problems as described above, the purpose of which is, the pipe is drawn out one by one on the rear of the inclined pipe supply unit in which a plurality of cutting pipes are stacked in the center of the table of the chamfering machine (grinding machine) And a partition part is installed so as to be supplied, and an inclined pipe alignment part in which the drawn pipes are sequentially aligned is installed at the rear of the pipe supply part, and a cylindrical shape is supported and fixed to the shaft via a driving motor at the rear of the pipe alignment part. A pipe withdrawal cam is installed, and an upper side of the pipe withdrawal cam is connected to both sides of the pipe by a guide bar via a vacuum cylinder, and a vacuum adsorption tube is extended so as to be lifted up and down through a vacuum cylinder. A slightly lifted wave is absorbed through the vacuum suction tube on both sides of the drawing cam. Both sides of the rope are rotatably installed so that the motor and the spindle can be rotated, and the motor and the spindle can be rotated before and after the transfer cylinder is connected to both sides of the spindle. After cutting the pipe to a certain length, a plurality of cut pipes are stored in the inclined pipe supply unit and are uniformly arranged one by one through the inclined pipe alignment unit, and the aligned pipes are cylindrical pipe withdrawal cams. Automatically withdraws one by one through the front and back of the spindle and the motor and the spindle, so that the burrs existing after the cutting process on the both sides of the pipe can be easily and easily removed, of course, While improving the chamfering work efficiency of the cutting pipe, An object of the present invention is to provide an automatic pipe chamfering device that can completely prevent worker safety accidents.

The present invention as a technical means for achieving the above object, in the pipe automatic chamfering device,

The pipe guide jaw is formed to be connected to the inclined pipe aligning unit is arranged to sequentially fetch the pipe, the rear pipe alignment unit is installed in the cylindrical pipe withdrawal cam that is supported and rotated on the shaft via a drive motor The pipe withdrawal cam has a plurality of pipe settling grooves on the main surface so that the pipes are placed one by one and rotated, and the upper and lower portions of the pipe withdrawal cams are moved up and down by adsorbing both ends of the pipes to both sides via guide bars. The cylinder and the discharged vacuum suction tube are connected through the vacuum cylinder. The upper and lower sides of the pipe drawing cam are rotatably installed on both sides of the pipe, which are sucked through the vacuum suction tube and chamfered on both sides of the slightly elevated pipe, so that the motor and the extended spindle are moved forward and backward. By providing a pipe automatic chamfering device, characterized in that the transfer cylinder is configured to be connected to each side of the spindle.

In addition, the present invention is characterized in that both sides of the pipe take-out cam is installed in the arc guide guide to be fixed to support both side ends of the pipe which is placed in the pipe settling groove of the pipe take-out cam is transferred upward.

According to the pipe automatic chamfering device of the present invention, after cutting the pipe used for laundry drying racks or hangers to a certain length, a plurality of cut pipes are stored in the inclined pipe supply and uniformly one by one through the inclined pipe alignment unit The aligned pipes are automatically drawn out one by one through the cylindrical pipe pull-out cam, and the burrs existing after the cutting process are cut on both sides of the pipe by the front and rear conveying of the spindle and the motor. It can be easily and easily removed automatically, as well as further improve the chamfering work efficiency of the cutting pipe, there is an excellent effect that can completely prevent the safety accidents of the operator when chamfering the pipe.
