BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 shows a general constitutional view in a schematic form of an example embodying the present invention,
FIG. 2 is a side elevation showing a forging press and a trimming press,
FIG. 3 is a cross sectional view of the same, and
FIG. 4 is a block diagram of the control system.
DETAILED DESCRIPTION OF THE INVENTION The invention will now be described referring to an embodimental example shown in the drawings. The apparatus according to the present invention is constituted by each of the devices shown schematically in FIG. 1. Namely, the numeral 1 designates a heating device for a material to be forged, and in general, a highfrequency induction heating furnace is used therefor. The material A which had been carried in from an entrance (right side in the drawing) side of the heating device l and has been heated to a forgingtemperature is carried to the body 3 of the forging press by means of a chain conveyer 2 provided at the exit (left side in the drawing) side of the, heating device l..An inspecting mechanism 4 is providedon the way to the chain conveyer 2 for checking the temperature and. the form of the heated material A, and the material A which is detected to be faulty by the inspecting mechanism 4"is dropped off to a material-discharging palette 5. Aloading chute 6 bent substantially to an L-shape along the side surface of the press 3 is provided at the end of the chain conveyer 2, and the loading chute 6 reaches up to a material loader 7 provided laterally of the body 3. The material loader 7 is provided with a piston-cylinder means 7a for pushing out the material A one by one which has been dropped off the loading chute 6, and the material A pushed out by the piston-cylinder means 7a is fed'to a metal mold 8 of the first stage in among a plurality of metal molds 8 provided in the forging press 3. A transferable industrial manipulator 9 is provided along the side of the body 7 at the side (generally, a'position apart from said material loader is preferable) of the forging press 3. The industrial manipulator 9 is formed of a rotary head 11 projectingly provided on a base 10 which is transferrable along the side surface of the forging press 3, and an arm 12 is protruded horizontally from the front surface of the rotary head 11 towards the metal molds 8 of the body 3. The arm 12 is made freely to advance and retreat by a driving means (not shown) arranged in the rotary head 11, and a grip means 13 is provided at the tip end of the arm 12 for gripping the material A. The first-stage metal mold 8, fed by the material loader 7 is gripped by said industrial manipulator 9, and the material A is set at a right position of the first-stage metal mold 8 for the forging thereof. The forging press 3 is provided with four supporting posts 15 provided around a bolster 14, and an oiLpressure producing means (not shown) and a plurality of oil pressure cylinder means 16 driven by said oil-pressure producing means are provided on the top end of the supporting posts 15, and an upper mold die set 18 which is movable freely up and down along a guide post 17 provided on said bolster 14 is driven up and down by means of said oil-pressure means. The metal molds 8 are arranged between the upper surface of the lower mold die set 19 and the lower surface of the upper mold die set 18 on said bolster 14 as shown in FIG. 3.
Another industrial manipulator 20 is provided opposite said industrial manipulator 9 and the group of metal molds 8. While said industrial manipulator 9 places the material A carried by. the material loader 7 in position relative to each of the metal molds 8 and transfers the material from the first-stage metal mold 8 to the intermediate-stage metal mold 8 and to the final-stage metal mold 8 with each of the forging processes, the industrial manipulator 20 operates to take out the material A which has been forged from the metal molds 8, and to carry the material into a trimming press 21 provided laterally of the forging press 3. The industrial manipulator 20 has a base 23 which is retreatable on rails 22, and rotary head 24 is projectingly provided on the base 23. An arm 25 is retreatably protruded in front of the rotary head 24. A grip means 26 which can grip the material A is provided at the tip end of the arm 25. Said trimming press 21 is installed laterally of the rails 22, which cuts protruded portions from the material A which has been forged and introduced by the arm'25 of the industrial manipulator 20 thereby to complete the work. For this purpose, a conventional type of trimming press can be used.
Each of the devices constituted as above are completely controlled by a controlling device'as will be described in the following. Namely, as shown in FIG. 4, said controlling device is adapted to control various devices in accordance with a program which has been established previously. In order to improve the efficiency, the control system is divided into two groups: the first control system comprises a material loader 7, a heating device 1, the forging press 3, and a traversible industrial manipulator 9, and the second control system comprises a trimming press 21 and an industrial manipulator 20. Each of the control systems can reduce the cycle time by carrying out the program independently, and each of the control systems can carry out simultaneously the program in synchronism when necessary. The previously established program is first applied to the data processing device 30. The data processing device 30 analyzes the given program, and at first, transmits a take out signal for the material A to the heating device, and at the same time transmits a preparation completion signal to the material loader 7. The material A carried out of the heating device 1 is transferred to the side of the forging press 3 by a chain conveyer 2, and is fed to the material loader 7 through a loading chute 6. When a fault of the material A, for example, inadequacy of forging temperature, or inferiority of the shape, is detected during these processes, a bypass instruction of the material is transmitted from the data processing device to the material loader 7, thereby the material is caused to drop into the material discharging pallet 5 without being operated to carry the material. When the forgeable material A is fed into the material loader 7, a loading signal is transmitted from the material loader 7 to the data processing device 30, and at the same time the material loader 7 starts the operation to push the material A into the forging press 3. The material A fed into the forging press 3 is gripped by a gripping means 13 provided at the tip end of the arm 12 with the operation of the industrial manipulator 9, and the material A is placed at an appropriate position relative to the first-stage metal mold 8 Upon the completion of the operation of the industrial manipulator 9, a completion signal is transmitted to the data processing device 30, and the device 30 transmits an operation order signal to the forging press 3 basing upon said completion signal. Hereupon the forging press 3 commences the operation, and when the forging of the material A fed to the first-stage metal mold 8 is finished, transmits an operation completion signal to the data processing device, and the device transmits a driving order to the industrial manipulator 9 in accordance with the program, and causes said manipulator to transfer the material A, which has been forged in the firststage metal mold 8 to the metal mold 8 of the following stage while reversing the material A. All this while, a lock signal is applied to the forging press 3, and the press is not operated during the operation of the industrial manipulator 9. At this time a compensating operation due to an inching and stopping to the industrial manipulator 9 can be effected by a control panel 31 directly connected to the data processing device 30. When the forging is finished at the final-stage metal mold 8 by repeating the above-mentioned operations, a completion signal is transmitted from the forging press 3 to the data processing device 30, thereby all the operations in the first control system is completed, and a signal is delivered to the second control system. In the second control system, with the completion of operations in the first control system, a driving order of ON- OF F is first transmitted from the data processing device 30 to the industrial manipulator 20, thereby the operation of the industrial manipulator is commenced.
The industrial manipulator 20 grips the material A which has been forged in the final-stage metal mold 8 and retreats with the material A, and after causing the rotary head 24 to rotate by causing the arm 25 to extend thereby to carry the material A gripped at the end of the arm into the trimming press 21. Upon completion of the carrying, a completion signal is transmitted to the data processing device 30. Next, the data processing device transmits an operation order signal to the trimming press 21 to operate it, which cuts off excess portions protruding out of the circumference of the material A, and works to finish the material A as a forged product. The product, having been finished by the trimming press 21, is carried outside of the trim ming press 21 by a delivery means which is not shown. In this second control system, as in the first control system, the industrial manipulator 20 is locked during the operation of the trimming press 21, and conversely, the trimming press 21 is interlocked during the operation of the manipulator 20. The mutual correction between the industrial manipulator 20 and the trimming press 21 can be effected by the inching and stopping instructed by the control panel 31.
As described above in detail, the present invention comprises a heating furnace for heating the material to be forged to a forging temperature, a material loader for carrying the heated material into a forging press, an
industrial manipulator for locating, reversing and transferring the introduced material to a'position relative to a metal mold in the press, an industrial manipulator for taking out the forged material and feeding it into a trimming press installed laterally of the forging press, a trimming press for effecting finish work by removing protruding portions from the forged material, and a data processing device for transmitting order signals based on previously established programs for each of the above-mentioned machines and devices and for instructing succeeding operations by operation completion signals sent back from each of the devices. Thus, it is possible to carry out a forging operation, which heretofore has all been performed artificially, by manless automatic operation, whereby a remarkable improvement in the working efficiency can be obtained, and at the same time safety of the workers can be maintained because of the elimination of artificial working in an unfavorable environment. Especially, an enormous installation for preserving favorable environment, which has been required for improving working condition, becomes almost unnecessary, and the forged products can be produced more economically.
