Description

  The present invention relates to a processing oil application apparatus that applies press working oil to a press work material and a press working die.

  Conventionally, press working oil (hereinafter referred to as “working oil”) to press working material (hereinafter referred to as “working material”) and a die for pressing (hereinafter referred to as “mold”) For the purpose of application, it is equipped with a nozzle that atomizes the processing oil by the negative pressure of the pressure air and sprays it as an oil mist toward the required part. There has been proposed a processing oil application device that controls processing oil spraying and stop timing by a control device that opens and closes an electromagnetic valve provided (see, for example, Patent Document 1). According to the configuration of this processing oil application device, during the continuous operation of the press machine, the processing oil spray (intermittent application) can be performed only at the timing when the processing oil spray is necessary, and the amount of processing oil used can be reduced. It becomes possible to reduce.

  By the way, with respect to the product processed in this way, a cleaning process for removing the attached processing oil is performed as necessary. However, in recent years, for the purpose of preventing deformation and scratches due to contact between products during cleaning and reducing the number of man-hours, volatile processing oil is used instead of normal processing oil, and the cleaning process is also omitted. .

  However, if the above volatile processing oil is used during progressive press processing with a large number of processes, the processing oil applied at the stage of feeding the workpiece into the mold volatilizes while moving in the mold along with the workpiece. May end up. In this case, it is necessary to apply additional processing oil to the workpiece and the mold in the middle of the process.

  Here, when the above-mentioned additional processing oil is applied in progressive press processing by a general-purpose press, the processing oil application device has different processing oil application conditions (applications) for each mold (processed product) to be attached. Therefore, it is required that the processing oil application conditions can be changed appropriately according to the mold to be attached.

  As an example of the prior art applicable to the above case, a processing oil coating apparatus disclosed in Patent Document 2 is disclosed. The processing oil coating apparatus is provided with an injector provided with an injection rod for spraying the processing oil by pressure air, and the injector is an arbitrary press machine depending on a die to be used by a magnetic base. It is possible to install in the position. If this processing oil application device is used, the application conditions of the processing oil can be made appropriate according to the mold to be installed by adjusting the installation location and number of the injectors. It is possible to sufficiently obtain the effect.

  By the way, in the processing oil coating apparatus having a nozzle for atomizing the processing oil by the negative pressure of the pressure air as in the prior art, the processing oil is atomized from the opening of the electromagnetic valve that opens and closes the flow path of the pressure air. There is a time lag associated with air transfer to the nozzle and pressure transmission before spraying is actually started. Further, since the processing oil after spraying is in an oil mist state, the moving speed is slow, and it takes time to reach the necessary part.

  In addition, even after the solenoid valve is closed, the ejection of air does not stop instantaneously, and the stopping of spraying of the processing oil is delayed, causing a problem in response.

  For this reason, when the press machine is operated at a high speed, the application of machining oil may not be able to follow the machining cycle even if the solenoid valve is opened and closed by the control device based on the timing signal from the press machine.

  Therefore, when using a press machine at high speed for processing thin sheet products, it is necessary to reliably apply the processing oil to the required part, so regardless of the open / closed state of the mold (based on the timing signal from the press machine). It was necessary to continuously spray the processing oil (with canceling the control), and the amount of processing oil used tended to increase.

  Also, since the pressure air is ejected from the nozzle, the spray pattern is easy to spread, and the processing oil that is actually applied to the part where the processing oil is applied is only a part of the sprayed processing oil, These processing oils were wasted because they adhered to areas where application was unnecessary or were released into the atmosphere. Further, a lot of processing oil was wasted such that a large amount of soot from the processing oil adhering to the nozzle was dripped. Such an increase in the amount of processing oil used has led to an increase in the running cost of the press machine because volatile processing oil is generally more expensive than ordinary processing oil.

  In addition, there is a problem that the amount of pressure air expelled for spraying the processing oil is large and energy consumption for supplying the pressure air is large. There is also a problem that a large amount of processing oil sprayed more than necessary volatilizes and diffuses, adversely affecting the working environment in the factory.

  As described above, the conventional press working oil application apparatus has room for improvement from the viewpoints of cost, energy saving, resource saving and safety and hygiene, and the present invention has such a conventional working oil applicator. It solves the problems that have been solved, and can be set appropriately by changing the application conditions of the processing oil according to the mold to be installed, and reliable processing oil application and processing oil / pressure air consumption during high-speed operation of the press An object of the present invention is to realize a press working oil coating apparatus that can achieve both reduction in quantity.

In order to solve the above-mentioned problems, a first invention is a press working oil coating apparatus, which is installed around a press working die attached to a press machine, and uses only the press working oil as a press working material and the press working. It consists of a coating unit that discharges toward the mold, and a main body that is installed outside the press.
The coating unit section is adjacent to the processing oil flow path through which the press working oil passes, the discharge section formed at the end of the processing oil flow path with pores through which the press working oil is discharged, and the discharge section. And a solenoid valve that opens and closes the processing oil flow passage, and the installation position in the press can be changed according to the press mold used.
The main body includes a pressurizing unit that supplies press working oil to the working oil flow passage of the coating unit in a pressurized state, and a control unit that drives the electromagnetic valve based on a signal output from the press. It is characterized by that. Accordingly, it is possible to realize a press working oil application apparatus that can apply the working oil to a necessary portion with the minimum necessary working oil consumption without the need for jetting of pressure air.

  According to a second aspect of the present invention, in the press working oil coating apparatus according to the first aspect of the present invention, at least one of the coating unit sections is integrated with the processing oil flow passage, the discharge section, and the electromagnetic valve. An injector is provided. As a result, the responsiveness is further improved, the structure of the coating unit is simple, the degree of freedom of attachment is high, and a press working oil coating apparatus that can easily cope with specification changes can be realized.

  According to a third aspect of the present invention, in the press working oil coating apparatus according to the second invention, the coating unit is fixed to a press machine and a support unit that supports the injector so that the discharge direction of the press working oil can be adjusted. And a base portion. As a result, it is possible to realize a press working oil application apparatus that can easily adjust the discharge direction of the working oil.

  The fourth invention is a press working oil application method, in which an injector provided with a solenoid valve is disposed at an arbitrary position around a mold attached to a press machine and is pressurized by a pressurizing means. By supplying the processing oil to the injector and controlling the operation of the injector by the control means that drives the solenoid valve based on the processing timing signal output from the press machine, only the press working oil is synchronized with the processing cycle of the press machine. Is discharged toward a press-working material and a press-working die. This makes it possible to achieve both reliable application of processing oil during high-speed press processing and reduction in the amount of processing oil used.

  According to the present invention, it is possible to achieve both reliable application of processing oil during high-speed press processing and reduction in consumption of processing oil and pressure air, and the running cost of the press machine can be reduced. In addition, the factory working environment can be improved.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is an overall view showing a press working oil coating apparatus according to an embodiment of the present invention. Note that the press working oil application apparatus described in the present embodiment is used for the purpose of applying work oil to a work material and a mold in order to improve lubrication and workability in progressive press work.

  The press working oil coating apparatus 10 includes a main body unit 20 installed outside the press machine 100, and four coating unit units 60 fixed on a bolster 101 which is a die lower part 101b mounting part of the press machine 100. Has been. An oil feed tube 21 and an injector drive cable 22 are disposed between the main body 20 and the coating unit 60. A signal cable 23 is connected between the press machine 100 and the main body 20. Further, the press machine 100 and the mold 110 are known ones and will not be described.

  First, the structure of the coating unit 60 will be described with reference to FIGS. FIG. 2 is a configuration diagram of one coating unit 60. The coating unit 60 is attached to the magnetic base 80 and the magnetic base 80 as a base fixed to the bolster 101 of the injector 70 and the press 100, and is held as a support that holds the injector 70 in a desired posture. The arm 90 is configured. Further, one end of the oil feeding tube 21 and one end of the injector drive cable 22 are connected to the injector 70.

  The magnetic base 80 is well known as an instrument that is fixed to an iron part such as a processing facility or work desk by the magnetic force of a built-in magnet by the operation of a lever 81 disposed on the fixed block 83. A round bar-shaped mounting portion 82 extending upward is disposed on the upper surface.

  As shown in the schematic diagram of FIG. 3, the injector 70 is a solenoid injector in which the machining oil flow passage 71, the electromagnetic valve 72, and the discharge unit 73 are integrated into a small unit. A pore 73 a is opened in the discharge part 73. The injector 70 is a device that discharges the pressurized liquid supplied to the processing oil flow passage 71 from the discharge portion 73 by energizing the electromagnetic valve 72, and is generally used in a fuel injection system of a vehicle or the like. Since the detailed structure and the operating principle are omitted, the appropriate valve structure and discharge pattern are selected and used in accordance with the processing oil application conditions.

  One end of the oil feeding tube 21 is connected to one end of the processing oil flow passage 71. One end of the injector drive cable 22 is connected to a winding coil (not shown) of the solenoid valve 72. Thus, when the press working oil application apparatus 10 is in use, the working oil is supplied to the working oil flow passage 71 from the main body 20 through the oil feed tube 21 in a pressurized state, and the solenoid valve 72 is supplied from the main body 20 to the injector. When energized through the drive cable 22, the winding coil is excited and opened.

  The holding arm 90 is fixed to the other end of the column 91 and the base side fixing unit 92 that is provided at one end of the column 91 and is fixed to the mounting unit 82. The injector side fixing portion 93 that holds the injector 70 is configured. The injector-side fixing portion 93 is provided with a housing 93a that holds the outer peripheral portion of the injector 70, and the injector 70 is fixed to the housing 93a with a mounting screw 93b.

  The base side fixing portion 92 and the injector side fixing portion 93 are clamped and fixed to the attachment portion 82 and the support column 91, respectively, by tightening fixing screws 92a and 92b, respectively, and the longitudinal position and the circumferential direction of the attachment portion 82 and the support column 91, respectively. The rotation angle along the axis can be adjusted. By changing the holding posture of the injector 70 by this adjustment mechanism, the discharge direction of the processing oil can be adjusted, and the fixing position of the coating unit 60 to the press 100 can be given a degree of freedom. Yes.

  Here, the processing oil discharge operation of the coating unit 60 will be described. When the solenoid valve 72 of the injector 70 is energized from the main body 20 of the press working oil application device 10 through the injector drive cable 22 and the solenoid valve 72 is opened, the pressurized working oil in the working oil flow passage 71 is discharged to the discharge portion 73. And is pushed out of the pore 73a and discharged out of the injector 70. At this time, the processing oil is greatly narrowed by the pores 73a in a pressurized state, and is discharged at a high speed. In the schematic diagram of FIG. 3 (B), the tip of the electromagnetic valve 72 is configured to close / open the processing oil flow passage 71 at a portion different from the pore 73a, but the pore 73a is directly connected to the electromagnetic valve 72. It is good also as a structure closed / open | released by the front-end | tip.

  According to the present invention, the required amount of processing oil can be applied to a required portion in a short time by the above-described high-pressure and high-speed discharge. Further, since the discharged processing oil is not mixed with the pressure air, it is difficult to diffuse, and the application can be limited to the vicinity of the portion where the processing oil is applied. For this reason, the amount of processing oil to be discharged is very small as compared with a method in which the processing oil is mixed and sprayed with pressure air, and the consumption of processing oil is greatly reduced.

  Further, in the present invention, the solenoid valve 72 and the discharge portion 73 are disposed close to each other in the application unit 60, and the processing oil is instantaneously moved from the solenoid valve 72 to the discharge portion 73. Compared with the spray nozzle by, the time lag from the opening of the electromagnetic valve 72 until the processing oil is discharged is reduced and the responsiveness is improved. In particular, in the present embodiment in which the electromagnetic valve 72 and the discharge portion 73 are integrated as the injector 70, it is possible to discharge the processing oil with almost no time lag. Moreover, since the change of the processing oil discharge direction is performed by changing the holding posture of the injector 70, the positional relationship between the electromagnetic valve 72 and the discharge portion 73 does not change, and the responsiveness is not impaired. For this reason, the processing oil discharge / stop operation following the high-speed operation of the press machine 100 is possible.

  Further, in the present invention, only the processing oil is discharged at the pressure applied to the processing oil by the main body portion 20 and the pressure air is not ejected, so that the influence on the cost and energy consumption due to the consumption of the pressure air is eliminated. Further, the tube for transferring the pressure air connected to the coating unit 60 is unnecessary, and the injector drive cable 22 required in the present invention is composed of a thin electric wire and has a high degree of freedom in handling. There are few restrictions on the fixed position and the holding posture of the injector 70.

  And in the application unit part 60 of this Embodiment, the process oil flow path 71, the solenoid valve 72, and the discharge part 73 are integrated as the injector 70, and can be handled as one unit component. Therefore, the configuration is simplified, and the application unit 60 can be easily assembled and adjusted.

  In addition, the structure in which the holding posture of the injector 70 itself can be easily changed by the holding arm 90 makes it easy to adjust the processing oil discharge direction. In addition, it is easy to change the specifications of the coating unit 60 by changing the size and shape of the magnetic base 80 and the holding arm 90 and replacing the injector 70 (to products with different discharge patterns).

  Furthermore, taking advantage of the feature of the injector 70 that is compact, the discharge unit 73 can be arranged close to the site where the processing oil is required, and the processing oil can be reliably applied to the required site with the minimum required discharge amount. It is. The application unit 60 can be directly fixed to the mold 110 as long as the operation of the mold 110 is not hindered.

  Next, the structure of the main body 20 will be described with reference to FIGS. FIG. 4 is a front view of the main body 20. FIG. 5 is a side view as viewed in the direction A in FIG. The main body unit 20 includes a gantry unit 30, a pressurizing unit 40 fixed to the upper part of the gantry unit 30, and a control unit 50 fixed to the front side of the pressurizing unit 40.

  The gantry 30 is formed by combining a prismatic leg 32 on a flat base 31 and a caster 33 for movement is attached to the bottom of the base 31 at its four corners.

  The pressurizing unit 40 has a rectangular parallelepiped tank main body 41, a processing oil supply port 41a disposed outside the tank main body 41, a filter regulator 42, an oil filter 43, a processing oil residual gauge 41b, and various tubes and joints. Consists of classes.

  In the use state of the press working oil application device 10, the working oil supplied from the working oil replenishing port 41a is accumulated in the tank body 41, and the pressure air sent from the air compressor (not shown) to the pressurizing unit 40 is After the foreign matter is removed and the pressure is reduced by the filter regulator 42, the air is supplied into the tank body 41 from the pressure air supply port 41 c at the top of the tank body 41. The pressurizing unit 40 is a device that pressurizes the processing oil with the pressure air as processing oil pressurizing means and sends it out from the processing oil delivery port 41d. Since the pressurizing unit 40 is known as a so-called pumping tank, its detailed structure and operating principle are described. However, since the pressure air is not sent together with the processing oil only by applying pressure to the processing oil in the tank body 41, the pressure air is basically hardly consumed.

  The processing oil sent from the processing oil delivery port 41d is sent to the oil filter 43 to remove foreign matter, and then branched into four oil feeding tubes 21 by the distribution unit 43a and sent to the coating unit 60 side. .

  A processing oil remaining amount gauge 41 b is provided on the back surface of the tank body 41. The processing oil remaining amount gauge 41b is obtained by connecting each end of a transparent tube to a joint disposed vertically. The processing oil remaining amount gauge 41b communicates with the inside of the tank main body 41, and displays the remaining amount of processing oil according to the liquid level in the transparent tube. It is also possible to provide a float switch inside the tank body 41 and electrically connect to the press machine 100 so that the press machine 100 automatically stops when the processing oil runs out. In addition, as a pressurizing means of the present invention, various methods such as feeding the processing oil to the coating unit 60 side by a pump can be taken in addition to using a pressure feeding tank as in the present embodiment.

  FIG. 6 is a perspective view of the control unit 50. FIG. 7 is a perspective view in which one surface of the control unit 50 is removed for explaining the internal structure. The control unit 50 includes a control unit casing 51, an injector driving power source 52, a control power source 53, a control unit 54, a switching unit 55, and various electric wires connected thereto. It is configured. In FIG. 7, various electric wires arranged in the control unit casing 51 are omitted for easy understanding of the structure.

  The lower surface of the control unit casing 51 is open, the signal cable 23 having one end connected to the press 100, four sets of injector drive cables 22 having one end connected to each coating unit 60, and an AC 100 (not shown). A power cable from the bolt power supply is introduced into the control unit casing 51 through the opening. The signal cable 23 is connected to the control device 54, the four sets of injector driving cables 22 are connected to the switching unit 55 and the injector driving power supply device 52, and the power supply cable is branched to the injector driving power supply device 52 and the control power supply device 53. Each is connected.

  The injector driving power supply device 52 is a known stabilized power supply device for converting an AC 100 volt power supply (not shown) into an operating voltage DC12V of the injector 70 provided in the coating unit 60, and a detailed description thereof will be omitted. Similarly, the control power supply 53 is a well-known stabilized power supply for converting an AC 100 volt power supply (not shown) to an operating voltage DC24V of the control device 54 and the switching unit 55, and therefore, details of the control power supply 53 are not described. Omitted.

  The control device 54 is configured by a well-known PLC (programmable logic controller) having a plurality of input units and a plurality of output units (not shown). Power is supplied from the control power supply unit 53 and a machining timing signal from the press 100 is supplied. The non-contact relay 55a of the switching unit 55 is opened and closed at an arbitrary timing and time.

  The switching unit 55 is a unit that switches between energization / non-energization from the injector driving power supply device 52 to the solenoid valve 72 of each injector 70, and a non-contact relay (solid state relay) 55 a that is operated by the control device 54. 4 units are installed for 60 bases. Each contactless relay 55 a can be individually operated by the control device 54. In this embodiment, the non-contact relay 55a is used with an emphasis on the operation speed. However, when the operation speed is not important, a relay unit can be configured using a normal solenoid relay.

  On the front surface of the control unit casing 51, four sets of start switches 51a and operation check lamps 51b corresponding to one coating unit 60 are arranged. The activation switch 51a is a toggle switch, and activation / deactivation can be selected for each coating unit 60. The operation confirmation lamp 51b is turned on when the injector 70 is energized.

  Further, an application amount adjustment switch 51c is disposed on the front surface of the control unit casing 51. The application amount adjustment switch 51 c is a combination of four known digital switches, and one application switch 60 c of the application amount adjustment switch 51 c corresponds to one application unit 60. By operating the application amount adjustment switch 51c, the operator can select 10 application amounts for each application unit 60.

  Here, the control performed by the control unit 50 will be described. When a timing signal indicating that the stroke position has reached the bottom dead center (the state in which the mold 110 is closed) is input from the press 100 through the signal cable 23 to the control device 54, the control device 54 is set to the set program. Based on the timing signal input, the control side energization state of the contactless relay 55a is turned on after a predetermined time (delay time) has elapsed. As a result, the injector drive circuit is energized, the solenoid valve of the injector 70 is opened, and the processing oil in the processing oil flow passage 71 is discharged. By this control, discharge of the processing oil is started from the injector 70 of the coating unit 60 after a lapse of a certain time from the input of the timing signal.

  Further, after a predetermined time (energization time) has elapsed, the control device 54 performs control to turn off the control-side energization state of the contactless relay 55a based on the program contents, the injector drive circuit is shut off, and the solenoid valve 72 of the injector 70 is closed. It is valved and the discharge of processing oil stops. By this control, the discharge of the processing oil from the injector 70 of the coating unit 60 is stopped after a certain time has elapsed since the start.

  In the present embodiment, the amount of processing oil applied is determined by the valve opening time of the injector 70. The energization time to the injector 70 corresponding to the valve opening time is programmed corresponding to 10 types of input states to the control device 54 depending on the selection position of the application amount adjustment switch 51c, and the product to be processed and the application unit Depending on the installation position of the unit 60, the operator can adjust the application amount adjustment switch 51c in 10 steps. Further, since one digi switch of the application amount adjusting switch 51c and one contactless relay 55a1 correspond to one application unit 60, and the control device 54 performs control for each contactless relay 55a1, each application unit section It is possible to set different application amounts for each of 60.

  Next, an example of processing oil discharge in conjunction with the operation of the press according to this embodiment will be described with reference to FIGS. 8A to 8C. FIGS. 8A to 8C show a cross-section as viewed in the direction of the arrows in the dashed-dotted line AA shown in FIG. FIG. 8A shows a state of the mold 110 when the slide portion 102 of the press machine 100 is at the bottom dead center position of the stroke. In this state, the mold 110 is closed, and the processing material 111 and the mold processing part 110c, which are parts requiring the processing oil application, are not exposed to the outside, and it is not necessary to discharge the processing oil. At this time, in the press working oil application device 10, the control side energization state of the contactless relay 55a is turned off by the control device 54, so that the working oil is not discharged from the injector 70.

  Subsequently, as shown in FIG. 8B, the slide part 102 starts to rise as the crank (not shown) of the press machine 100 rotates, and the mold upper part 110a attached to the slide part 102 also starts to rise. As a result, the mold 110 begins to open, and the workpiece 111 and the mold processing portion 110c begin to be exposed. Even at this time, the control-side energized state of the non-contact relay 55a of the processing oil coating apparatus 10 is turned OFF, It is not discharged from the injector 70.

  When the crank rotation of the press machine 100 further proceeds, as shown in FIG. 8C, the mold upper part 110a is further raised, and the workpiece 111 is fed by one process by a feeding device (not shown). The delay time programmed in the control device 54 is set so that the completion of the feed of the workpiece 111 and the start of the discharge of the machining oil are set simultaneously, and when the control-side energization state of the contactless relay 55a is turned on. Discharge of the processing oil is started from the injector 70, and the energization to the injector 70 is maintained for a time set for each selection position of the application amount adjustment switch 51c, so that the processing oil is discharged. This energization time is set so that the discharge of the processing oil is completed before the mold is closed again at the longest in order to prevent waste of the processing oil.

  By configuring the processing oil application device as described above, intermittent application of processing oil is possible following the high-speed processing cycle of progressive press processing, and the processing oil application conditions are optimized according to the product to be processed. A configurable processing oil application device can be realized. Thereby, consumption of expensive volatile processing oil and pressure air can be reduced, and the running cost of the press machine can be reduced and energy and resources can be saved. Moreover, deterioration of the factory environment due to the volatilized processing oil can be prevented.

  Note that the press working oil application device according to the present embodiment can be applied not only to volatile working oil but also to ordinary press working oil. Effective when additional oil application is required. In this case, the amount of non-volatilized processing oil adhering to the mold and the press machine is reduced by intermittent application of the processing oil, and the effect of reducing the man-hours for cleaning the mold and the press machine is also obtained.

  The press working oil application apparatus according to the present embodiment can also be used for additional application of working oil as an auxiliary to a general working oil coating apparatus that applies the working oil at the material feed section of the press machine. However, it is also possible to apply the processing oil only with the present press processing oil application apparatus. In that case, what is necessary is just to arrange | position a coating | coated unit part suitably so that a process oil may be apply | coated also in the first process in a progressive press work process.

  In the present embodiment, four coating unit units are provided, but the number of coating unit units may be changed as appropriate. Further, the control method is not limited to the one in the present embodiment, such as changing the processing oil discharge frequency with respect to the number of strokes of the press machine by the program setting of the control device. Also, the control of the processing oil discharge timing is not limited to the delay time for the crank bottom dead center signal input from the press machine, the crank rotation angle is monitored linearly for more precise control, and the crank rotation angle Various methods such as determining processing oil discharge timing can be taken.
