Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a forging roll facility. In die forging, a billet (material) heated in a heating furnace is passed through a die roll to create a rough ground, and then forged by forging. The present invention relates to forging roll equipment for creating wasteland in such a die forging press line.

[0002]

2. Description of the Related Art In a forging press line that uses forging rolls for preforming, the time required from a heating furnace through a forging roll to stamping in a forging press is reduced, and a billet is formed in the forging press. It is important to keep the temperature from decreasing so as to improve productivity.

First, the layout of a conventional forging roll facility will be described with reference to FIG. A is a forging roll, which includes a molding machine main body 1 and a manipulator unit 10. A roll drive shaft 3 extends from a side portion of the molding machine main body 1, and a mold roll 7 is attached to the roll drive shaft 3. The manipulator unit 10 is provided with a tongue 11, a screw rod 13, a motor 14, and the like. Then, as an entrance-side transfer facility for supplying a billet to the mold roll 7, an entrance-side conveyor 51 and an entry-side reversing device 5
2. There are an entrance side pusher 53, an entrance side elevating device 54 and the like.
The entrance conveyor 51 is connected to the chute 24 with respect to the heating furnace 21.
And the input side pusher 53 and the input side elevating device 5
4 is orthogonal to the line direction. The delivery conveyor 5 is used as a delivery device for the preformed billet.
6, 57 and an outlet pusher 58 are provided, and are connected to the charging device 30 by these. Then, a preformed billet is supplied to the forging press by the charging device 30. In the above conventional example, not only is the overall layout complicated, but also the heated billet has to travel a long distance via the entrance conveyor 51, the entrance reversing device 52 and the entrance elevating device 54, In the meantime, there was a problem that cooling was easy and productivity was poor.

To improve productivity, a layout as shown in FIG. 3 has recently been adopted. That is, only the chute 24 is used as the entrance-side transfer equipment,
The heating furnace 21 and the inlet pusher 25 are connected, and the use of the inlet conveyor is eliminated. In addition, 27 is a delivery conveyor, 29 is a billet reversing device, and 30 is a charging device. However, even in this conventional example, it takes time from the roll forming of the heated billet coming out of the heating furnace 21 to the forming by a forging press. Further, there is a problem that the installation height of the heating furnace 21 becomes extremely high.
In this case, in order to shorten the time from the heating furnace to stamping with a forging press, the above problem can be solved by adopting a layout in which the heating furnace is close to a mold roll. However,
Such a layout has not been adopted so far, because the heating furnace covers the manipulator unit and maintenance of the manipulator becomes impossible.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has as its object to provide a forging roll facility which can easily maintain a manipulator and the like while increasing productivity.

[0006]

According to a first aspect of the present invention, there is provided a forging roll comprising a manipulator unit for supplying a billet between a pair of mold rolls in a molding machine main body, and a billet supplied to the forging roll. In a forging roll facility comprising a heating furnace for heating the heating furnace, an outlet portion of the heating furnace is installed above the manipulator unit, and a rail for discharging the manipulator unit from below the outlet portion of the heating furnace to the outside. And a wheel that runs on the rail is attached to the manipulator unit.

According to the first aspect of the present invention, since the outlet side of the heating furnace is located above the manipulator unit, the distance between the heating furnace and the mold rolls becomes very short, and the billet temperature decreases. It is difficult to improve the productivity. Then, when the wheels of the manipulator unit are run on the rails and the manipulator unit is paid out from below the outlet part of the heating furnace, there is no obstruction on the upper surface, so maintenance and inspection work of the manipulator etc. can be easily performed. It can be carried out.

Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a side view of a forging roll facility according to an embodiment of the present invention, and FIG. 2 is a plan view of the forging roll facility.

First, the forging roll A will be described with reference to FIGS. Reference numeral 1 denotes a molding machine main body of a forging roll A, a motor 2a, a flywheel 2 with a built-in clutch.
b, a roll driving device 2 including a main gear 2c, a brake 2d, a pinion 2e, and the like. Two upper and lower roll drive shafts 3 are connected to the roll drive device 2.
A mold roll 7 for four passes of the set is attached.

In the manipulator unit 10,
A manipulator comprising a drive source and a drive mechanism for moving the manitoning 11 laterally and moving it back and forth is provided. That is, the manipulator referred to here is, for example, a screw rod 13 for traverse feed, a traverse motor 14, and a guide 1.
And a known mechanism such as a lever and a link that are interlocked with the rotation of the roll drive shaft 2 for moving the manifold forward and backward. A gripping mechanism for gripping a workpiece is attached to a tip of the manitoning 11, and can be gripped by an operating mechanism such as a hydraulic cylinder mounted on the manitoning 11. In the above-mentioned forging roll A, the workpiece can be gripped by the manifold 11 and passed between the upper and lower mold rolls 7 so that the mold can be formed. Upon molding, a desired rough land can be formed.

Reference numeral 21 denotes an induction heater, which corresponds to a heating furnace described in the claims. The main body of the induction heater 21 is located behind the manipulator unit 10, but its exit portion 21a is located above the manipulator unit 10 and at a height that is not far away. For this reason, maintenance and inspection of the manipulator and the like are impossible in this state.

The outlet side of the induction heater 21
A chute 24 is provided downstream from 21a, and is connected to a pusher 25 for billet insertion. The pusher 25 is connected to the chute 24 when inclined as shown by a solid line, and is opposed to between the upper and lower mold rolls 7 when turned to a horizontal state as shown by a broken line.

An output side conveyor 27 is provided on the output side of the mold roll 7, and on the output side of the output side conveyor 27,
A charging device 30 having a billet reversing device 29 is provided. By this charging device 30, the billet formed in the rough land is carried to the 0-step cradle of the forging press.

The manipulator unit 10 is separated from the base member 40, and wheels 41 are attached to four corners at its lower end. A rail 42 is laid on the upper surface of the base member 40. This rail 42
Is provided so that the manipulator unit 10 can be moved toward the outside in a direction of dispensing the manipulator unit 10 from below the outlet side portion 21a of the induction heater 21, for example, when a worker stands. The wheels 41 of the manipulator unit 10 run on the rails 42. The operation of paying out and returning the manipulator unit 10 may be performed manually, or an appropriate power source may be used.

In the case of the forging roll equipment of this embodiment, the length of the chute 24 is shortened because the exit side portion 21a of the induction heater 21 is located at a position close to the mold roll 7, so that the chute 24 is not moved. The heated billet sent does not cool much. For this reason, the formability in the forging press in the post-process is good, and the productivity is improved. Further, when performing maintenance, if the manipulator unit 10 is pulled out toward the user as shown by the imaginary line in FIG. The maintenance inspection work can be performed easily without the need.

[0016]

According to the first aspect of the present invention, since the outlet side portion of the heating furnace is located above the manipulator unit, the distance between the heating furnace and the mold roll is very short, and the billet temperature is reduced. Since it does not easily decrease, productivity is improved. When the wheels of the manipulator unit are run on the rails and dispensed to the outside from below the exit side of the induction heater, there is no obstruction on the upper surface, so that maintenance and inspection work of the manipulator and the like can be easily performed. it can.
