Description

Technical Field [0001] The present invention relates to a cutting tool for an outer edge of a molded metal pipe,

The present invention relates to a chamfering device for each end of a pipe, and more particularly, to a chamfering device for each end of a pipe, which is capable of uniformly chamfering both end portions of each pipe cut into a predetermined length and formed by each pipe, The present invention relates to a chamfering device for each end of a pipe.

There have been many studies to reduce pollutants emitted from automobiles worldwide. In the case of diesel engines, nitrogen oxides are difficult to develop due to adverse effects on combustion and fuel consumption. EGR (exhaust gas regulation) has been developed and widely used as a measure to reduce nitrogen oxides.

This technique reduces the nitrogen oxides in the exhaust gas in a manner that cools the exhaust gases as cooling water circulating along the interior of each tube to lower the temperature of the combustion chamber. Each pipe for the flow of cooling water is manufactured by conventional die casting or casting. However, in this case, the weight of each pipe is increased, and the production cost is increased. Therefore, a method of molding a metal plate into each pipe is mainly used.

That is, the metal sheet material is bent and formed into a U-shape by using a plurality of forming rollers arranged as shown in FIG. 5, the joint portions are welded to each pipe, and then cut into pieces each having a predetermined length as a grinder. At this time, if each pipe is cut by a predetermined length as a grinder, sharp edges are formed at the cut portion, and it is necessary to smoothly trim the pipe.

However, since the chamfering operation itself for each pipe cut to a certain length is carried out entirely by hand, there has been a problem in that the productivity is remarkably deteriorated due to an increase in the defective rate as well as quality deterioration due to non-uniform chamfering operation.

A schematic operating configuration of the present invention having such a configuration will be described with reference to the above-described description and each of FIGS. 4A to 4G attached hereto.

First, as shown in FIG. 4A, the left and right side portions of the rotary pipe 47 are positioned between the supply plate 51 and the back plate 61, and the ring 49 is brought into close contact with the end of the stopper 414. At this time, the third drive motor 45 does not operate, and each of the first and second pneumatic moving bodies 24 and 34 operates in one direction to maintain a state of being pushed for a certain distance in the left outer direction and the right outer direction.

When the control signal of the controller 12 is inputted in this state, the first and second driving motors 25 and 35 operate as shown in FIG. 4B so that the first and second polishing brushes 26 and 36 are kept in a state The second pneumatic cylinder 52 is operated so that the pressing rod 53 pushes one side of each of the pipes P which are stacked at the bottom of the supply plate 51, (47).

When each pipe P is inserted into the rotary pipe 47, the first pneumatic cylinder 43 operates in one direction according to the control signal of the controller 12 to move the movable plate 44 forward of the work table 10 , Both sides of each pipe P inserted in the rotary pipe 47 are opposed to the first and second polishing brushes 26 and 36 at a predetermined interval as shown in FIG. 4C.

When each of the two sides of each pipe P faces the first and second polishing brushes 26 and 36 which are rotating at a constant speed and spaced apart from each other by a predetermined distance, The first and second pneumatic moving bodies 24 and 34 are operated in the other direction.

Each of the first and second polishing brushes 26 and 36 rotates together with the rotary pipe 47 in accordance with the rotational force transmitted through the drive belt 48. Thus, (24, 34) and moves toward the central portion of the work table (10), and is brought into close contact with both end portions of each pipe (P).

4D, each pipe P is rotated at a constant speed together with the rotary pipe 47, and both end portions thereof are polished by the first and second polishing brushes 26 and 36. In this polishing process, Sharp cutting portions and welding beads remaining on both end portions of the workpiece P are smoothly smoothed.

The control signal is again inputted to the controller 12 after a predetermined period of time has elapsed according to the material and the thickness of each pipe. As a result, the third drive motor 45 stops operating as shown in FIG. 4E, Each of the brushes 26 and 36 returns to the original position together with each of the first and second pneumatic moving bodies 24 and 34 operating in one direction and both ends of each pipe P are connected to the first and second polishing brushes 26 and 36 Respectively. At this time, each of the first and second drive motors 25 and 35 keeps operating.

When the third drive motor 45 stops operating, the rotation of the rotary pipe 47 holding the pipes P is also stopped. The degree of rotation of the rotary pipe 47 according to the operation of the third drive motor 45 can be varied depending on the size and thickness of each pipe P and the degree of chamfering operation. .

When the operation of the third drive motor 45 is stopped, the ring 49 coupled to the rotary pipe 47 is rotated in the direction in which the portion where the buffer spring 494 is located is parallel to the stopper 414 Stop at position. The rotation of the rotary pipe 47 and the engagement of the limit switch (not shown) can be implemented to cause the ring 49 to stop at such a position, so that the description thereof will be omitted.

When the both ends of each pipe P are separated from the first and second polishing brushes 26 and 36, the first pneumatic cylinder 43 is operated in the other direction in accordance with the control signal of the controller 12, The pipe 47 is moved to the rear of the work table 10 and both side portions of the chamfered pipe P 'where the chamfering operation is completed are positioned between the supply plate 51 and the discharge plate 61 as shown in FIG.

When the rotary pipe 47 moves to the rear side of the work table 10 by the movable plate 44, the moving distance of the rotary pipe 47 is input to the controller 12 in advance, but the degree of the movement may deviate within a certain range. If the degree of movement of the rotary pipe 47 exceeds the previously inputted distance, movement of the rotary pipe 47 is restricted while the ring 49 contacts the stopper 414 as shown in Fig. 3, The impact is absorbed by the buffer spring 494.

In this state, if the second pneumatic cylinder 52 is operated again in accordance with the control signal of the controller 12, if one side of each pipe P mounted at the bottom of the supply plate 51 is pushed, Each pipe P 'inserted into the rotary pipe 47 is pushed by the new pipe P and is discharged to the discharge plate 61 as shown in 4f.

When the control signal of the controller 12 is subsequently input, the first pneumatic cylinder 43 operates in one direction to move the movable plate 44 forward of the workbench 10, and thereafter, as shown in Figs. 4B to 4F The chamfering operation for each pipe P is repeated while continuing the disclosed operations sequentially.

In the meantime, each pipe P 'discharged from the discharge plate 61 after the chamfering operation is completed is separated from the new pipe P in the process of moving the new pipe P requiring the chamfering operation to the front side of the workbench 10 by the movable plate 44 And is transmitted to an operator standing by in the vicinity of the work table 10 in accordance with an input control signal.

4 (g), when the third air pressure moving body 62 is operated and the movable rod 622 pushes the push plate 63 in one direction, the push plate 63 advances in one direction, (P ') is pushed out. Thus, the finished pipe P' is slid along the upper surface of the discharge plate 61, and then the worker completes the operation for the individual pipe by recovering it.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims. It will be apparent that the present invention can be practiced with added features.
