Description

Hot forging material High temperature reversing device

The present invention relates to a hot forging material high temperature unit reversing apparatus, and more particularly, the high temperature portion of the material is rotated by 180 ° in the plane in the process of transferring the material drawn from the heating portion to the forging molding portion by the guide rail. It relates to a hot forging material high temperature inverting device which is inverted to face.

As is well known, forging refers to a metal processing method for forming a material into a desired shape by applying a compressive load by a mechanical method, and generally forging at a temperature higher than the boundary at which the recrystallization proceeds in the material. It is called simple forging, and forging at lower temperature is called cold forging.

The hot forging corresponding to the former is to heat the steel at a high temperature of 1000 ℃ ~ 1250 ℃ to reduce the deformation resistance to give a large deformation with a small force, so that the molding can be easily performed, and the annealing effect is added to improve the material. It is one of the commonly used forging methods with the advantage of being able to produce a product with good productivity and easy formation because of its fast production speed.

On the other hand, in order to supply the material to the hot forging die, first, the round bar-shaped material is heated in a heating furnace at a temperature suitable for forging, and then the heated material is taken out of the heating furnace, and then automatically transferred to the hot forging die forming part. Forging is performed.

Representative prior art related to the hot forging material automatic supply device may be exemplified by Korean Patent Application Publication No. 10-2016-0071258.

The prior art is a material supply apparatus of a hot forging die for supplying the material to the forming portion of the hot forging die, the housing, the main frame is installed in the state penetrating through the housing and the gripper for clamping and unclamping the material at the tip And Y-axis drive means installed in the housing and including a carriage for moving the main frame in the Y-axis direction by the power of a servo motor in a state supported by a bearing under the main frame. X, which is disposed at the rear of the motor and moves the main frame mounted on the carriage with the bearings in the X-axis direction by the power of the servo motor, to supply the material clamped to the gripper to the molding part of the hot forging die. It comprises a shaft drive means.

However, the prior art is a method of gripping the material with a gripper, and then supplying the gripped material to the forming part of the hot forging die, which is a separate process of gripping the material with the gripper one by one and then supplying it to the forming part one by one. As a result, workability and productivity are deteriorated.

In recent years, after the material is discharged from the furnace, the forging operation proceeds by directly throwing the rail into the forging molding unit without a separate supply device.

However, the following problems are expected when the material is directly put in without the supply device.

In other words, when the material exits the outside of the heating furnace, the first part of the material that comes out first is cooled compared to the second part of the material that comes out later, and the temperature is different, that is, the front part of the material becomes a "low temperature" low temperature part, Is supplied to the forging molding part by rail in the state of being a high temperature part which is "high temperature". In this case, the low temperature part of the material having a lower temperature than the high temperature is precisely molded as the low temperature part of the material is inserted into the forging molding part. There is a problem that causes a large number of defects in operation.

Therefore, an object of the present invention for solving the problems as described above is to rotate the material 180 ° so that the high temperature portion of the material toward the forging molded part in the process of transferring the material drawn from the heating portion to the forging molded part on the guide rail It is to provide a hot forging material high-temperature inverting device for inverting the rear portion of the front facing forward.

The present invention for achieving the above object is a hot forging material hot portion reversing apparatus for rotating the material 180 degrees in a plane to reverse the high temperature portion of the material toward the front and the low temperature portion of the material toward the rear, discharge from the heating portion A first inclined guide rail for guiding the made material, and a front side of the first inclined rail, and an outer surface of which is provided with an accommodating part for accommodating the material moved on the first inclined rail; It is connected to the shaft and is driven in the power applied from the outside and composed of a drive means for rotating the rotating plate to invert the high temperature portion of the material accommodated in the accommodating portion and located in front of the rotating plate and the As the rotating plate rotates, the hot part faces forward and the cold part faces backward. And it characterized in that it comprises a second inclined guide rail to the guide so that when supplied to the group material can be discharged as part forging.

The first inclined rail, the inverting portion and the second inclined rail are preferably disposed to be inclined downward toward the front so that the material can descend to its own weight.

The present invention is to produce a more precise forged molded article by inducing the high temperature portion of the material to be inserted into the forged molding part by rotating the material exiting the heating furnace 180 ° to supply the high temperature portion of the material to the forging molded part in the state facing forward. It has an effect that can be done.
