[0008] <First embodiment> First, the first embodiment will be described. FIG. 1 is a front view showing the processing device according to the present embodiment. FIG. 2 is a front view showing the processing unit of the processing device according to this embodiment. In FIG. 2, the front member and door of the case of the processing part are omitted, and the inside of the processing part is shown.

[0009] The processing device 1 according to this embodiment is a processing device that performs cutting and hardening treatment on a steel material S. As shown in Fig. 1, the processing device 1 according to this embodiment is provided with a support table 10. A processing unit 20 is provided on the support table 10. In addition, a control unit 30 is provided on the support table 10 and to the side of the processing unit 20.

[0010] As shown in FIGS. 1 and 2, the processing section 20 is provided with a case 21, a partition member 22, a steel material supporting means 23, a cutting tool holding means 24, a conveying means 25, an induction heating means 26, and a cooling means 27.

[0011] The partition member 22, the steel material supporting means 23, the cutting tool holding means 24, the transporting means 25, and the induction heating means 26 are disposed within the case 21. In this specification, when a certain means is "disposed within the case 21," it means that at least a portion of the means that directly acts on the steel material S is disposed within the case 21, and the entire means does not necessarily have to be disposed within the case 21. For example, a power supply unit (not shown) that supplies power to each means of the processing section 20 may be provided inside the support table 10. Also, a control circuit for each means is provided in the control section 30.

[0012] The case 21 is provided with a wall material 21a and a door 21b, and the door 21b is provided with a window 21c. The wall material 21a constitutes five surfaces of the case 21 other than the front surface, that is, the bottom surface, the top surface, both sides, and the back surface, and further constitutes the front surface other than the door 21b. The door 21b is attached to the wall material 21a so as to be openable and closable. An operator can access the inside of the case 21 by opening the door 21b. Furthermore, by closing the door 21b, it is possible to prevent cutting chips generated inside the case 21 from scattering to the outside, to prevent heat generated by induction heating from being transferred to the outside, and to prevent the cooling liquid discharged from the cooling means 27 from leaking to the outside. Furthermore, with the door 21b closed, an operator can visually check the inside of the case 21 through the window 21c.

[0013] As shown in Fig. 2, the partitioning member 22 divides the inside of the case 21 into a space F1 and a space F2. However, the partitioning member 22 is not provided between a part of the space F1 and a part of the space F2, and a passage C is formed through which the steel material S can pass. The passage C is, for example, above the partitioning member 22. The steel material supporting means 23 and the cutting tool holding means 24 are arranged in the space F1. The induction heating means 26 and a part of the cooling means 27 are arranged in the space F2. The conveying means 25 conveys the steel material S between the space F1 and the space F2.

[0014] The steel material support means 23 is provided with a headstock 23a that holds one end of the steel material S and rotates the steel material S, and a tailstock 23b that rotatably supports the other end of the steel material S. The tailstock 23b urges the steel material S toward the headstock 23a. The steel material support means 23 rotatably supports the steel material S by sandwiching the steel material S between the headstock 23a and the tailstock 23b.

[0015] A tool rest 24a is provided at the tip of the tool holding means 24. The tool rest 24a holds a tool B for processing the steel material S. The tool rest 24a may be configured to be able to rotate the tool B. The tool B is, for example, a cutting tool. The tool holding means 24 can press the tool B against any position on the steel material S by moving the tool rest 24a three-dimensionally. The tool rest 24a may hold a plurality of types of tool B. In this case, the tool B to be used can be switched by rotating the tool rest 24a.

[0016] The conveying means 25 is constituted by, for example, an actuator such as a robot arm. The conveying means 25 holds the steel material S and moves the steel material S between the space F1 and the space F2 via the passage C.

[0017] The induction heating means 26 is provided with, for example, a coil 26a. The coil 26a is disposed, for example, at a position capable of surrounding the steel material S. The induction heating means 26 applies a high-frequency current to the coil 26a, thereby applying an induction current to a surface layer portion of the steel material S, thereby heating the steel material S.

[0018] The cooling means 27 is provided with a nozzle 27a and a cooling liquid supplying means 27b. The nozzle 27a is disposed in the space F2 of the case 21, and is movable within the space F2 and capable of spraying the cooling liquid onto the steel material S. The cooling liquid is, for example, water. The cooling liquid supplying means 27b is provided with a tank, piping, and a pump (not shown). The cooling liquid supplying means 27b holds the cooling liquid in the tank and supplies the cooling liquid to the nozzle 27a by the pump and piping. The cooling liquid discharged into the space F2 of the case 21 is returned to the tank via the piping. The cooling liquid supplying means 27b may be disposed, for example, in the support table 10. The cooling means 27 can rapidly cool the induction-heated steel material S and effectively perform quenching treatment.

[0019] The cooling means 27 may be integral with the coil 26a. For example, a jacket may be attached to the coil 26b, and the nozzle of the nozzle 27a may be provided in the jacket.

[0020] The control unit 30 controls the operation of the processing unit 20. The control unit 30 is provided with a calculation unit 31, an interface unit 32, and a communication unit 33. The calculation unit 31 is provided with, for example, a CPU (central processing unit) and a memory. The calculation unit 31 performs numerical control (NC) of the cutting tool holding means 24 and the transport means 25, for example.

[0021] The interface unit 32 exchanges information with an operator. The interface unit 32 is provided with, for example, a touch panel, a display panel, and a keyboard. The communication unit 33 exchanges information with the outside by electrical means. For example, a program for controlling the processing unit 20 may be input from the outside via the communication unit 33.

[0022] Next, the operation of the processing device 1 according to this embodiment will be described. 3(a) to 4(b) are diagrams showing the operation of the processing device according to this embodiment. 3(a) to 4(b) show only the inside of the processing unit 20. In order to make the drawings easier to see, components that are not used in each process are appropriately omitted from the illustration.

[0023] 1, a control program is installed in advance in a calculation unit 31 of the processing device 1 via a communication unit 33. An operator inputs necessary information to the calculation unit 31 via an interface unit 32.

[0024] Then, as shown in Figs. 1 and 3(a), the worker opens the door 21b of the case 21, and attaches the steel material S to the steel material support means 23 in the space F1. The steel material S is, for example, a round bar material. At this time, the headstock 23a holds one end of the steel material S, and the tailstock 23b rotatably supports the other end of the steel material S. The tailstock 23b urges the steel material S toward the headstock 23a. After that, the worker closes the door 21b, and operates the interface unit 32 to cause the processing device 1 to start processing. Subsequent operations are controlled by the calculation unit 31.

[0025] As shown in FIG. 3(b), the cutting tool holding means 24 presses the cutting tool B attached to the tool rest 24a against the steel material S. This cuts the steel material S into a predetermined shape. At this time, the steel material support means 23 and the cutting tool holding means 24 work together to process the steel material S. For example, the steel material support means 23 may fixedly hold the steel material S, and the cutting tool holding means 24 may rotate the cutting tool B to process the steel material S. Alternatively, the headstock 23a of the steel material support means 23 may rotate the steel material S, while the cutting tool holding means 24 presses the cutting tool B against the steel material S, thereby processing the steel material S like a lathe.

[0026] 3(c), the conveying means 25 grips the processed steel material S, and the steel material supporting means 23 releases the steel material S. Then, the conveying means 25 conveys the steel material S from the space F1 through the passage C to the space F2.

[0027] 4(a), the induction heating means 26 moves the coil 26a while passing a high-frequency current through the coil 26a, thereby inductively heating the steel material S. At this time, the coil 26a moves relative to the steel material S, so that the whole or a part of the steel material S is heated.

[0028] Next, as shown in FIG. 4(b), the cooling means 27 moves the nozzle 27a while discharging cooling liquid from the nozzle 27a toward the steel material S. At this time, the nozzle 27a moves relative to the steel material S, thereby cooling the whole or a part of the steel material S. This causes the steel material S to be quenched and the surface layer portion to be quenched. As a result, the surface layer portion of the steel material S is hardened. Note that the cooling by the cooling means 27 is performed only on the portion of the steel material S that has been heated by the induction heating means 26. In this manner, the steel material S is processed into a specified product.

[0029] Next, the effects of this embodiment will be described. In this embodiment, a steel material supporting means 23, a cutting tool holding means 24, and an induction heating means 26 are provided inside a case 21 of the processing device 1. This allows the processing device 1 to continuously perform cutting of the steel material S with the cutting tool B and hardening treatment by induction heating inside the case 21. Therefore, the processing device 1 has high product productivity.

[0030] In the present embodiment, the processing device 1 is provided with a cooling means 27, and a nozzle 27a of the cooling means 27 is disposed in the case 21. This allows the steel material S heated by the induction heating means 26 to be rapidly cooled in the case 21. As a result, the quenching treatment of the steel material S can be precisely controlled.

[0031] Furthermore, in this embodiment, a partition member 22 is provided in the case 21, and the inside of the case 21 is partitioned into a space F1 and a space F2. A steel material support means 23 and a cutting tool holding means 24 are arranged in the space F1, and an induction heating means 26 and a cooling means 27 are arranged in the space F2. This makes it possible to prevent cutting chips and the like from contaminating the space F2 when the steel material S is cut in the space F1. Also, it makes it possible to prevent the structure in the space F1 from being affected by heat when the steel material S is induction heated in the space F2. Furthermore, it makes it possible to prevent the coolant from entering the space F1 when the steel material S is cooled in the space F2.

[0032] The heating step shown in Fig. 4(b) and the cooling step shown in Fig. 4(b) may be performed overlapping in time. That is, the coil 26a may be moved relatively to the steel material S to perform induction heating, while the nozzle 27a may be moved to follow the coil 26a to perform cooling. In this case, each part of the steel material S is heated in sequence and cooled immediately thereafter. As a result, the time required for the heating step and the cooling step can be shortened, the quenching process can be controlled more precisely, and the productivity can be improved.

[0033] The above-described embodiment is an example of implementing the present invention, and the present invention is not limited to this embodiment. For example, the present invention also includes the above-described embodiment in which some components or steps are added, deleted, or changed. [Explanation of symbols]
