1376306 TECHNICAL FIELD OF THE INVENTION The present invention relates to a press apparatus for forming a sheet material formed of a resin material by means of hot pressing. [Prior Art]

In the past, in order to manufacture an IC card (integrated circuit card) such as a system, a circuit board (PW, a dragon (four), 4 rides formed stamping 2. Such a punch is placed between two hot plates, clipped The resin is mainly used, and the two are subjected to a heat pressing step when heating (4), thereby forming a product. In the case of using such a stamping device, for example, the forming thickness is reduced in the suppression: the printing In the case of the road plate, 'if the flatness accuracy of the hot plate is not within 10 micrometers', the pressure acting on the product is different depending on the hot plate, and the thickness of the printed circuit board is reduced in the thickness direction. And with the position where the pressure is applied, the pressure is not likely to be unfavorable.

Further, in recent years, since a plurality of forming can be produced by one pressing, a press device having a large hot plate can be employed. Since the area of the hot plate is large, it is difficult to ensure the flatness accuracy of the hot plate, so that it is not easy to avoid the phenomenon of the product. In the past, for example, the stamping device described in JP-A-196-195895 will even In the case where the surface of the rubber sheet or the like is small, and the surface is slightly deformed, the material which hardly affects the surface accuracy of the other surface is used as a cushioning material, and is sandwiched between the workpiece and the hot plate. However, since the thermal conductivity of the buffer material is extremely lower than that of the heat 6 1376306, the heat of the hot plate is difficult to be transmitted to the workpiece, and the molding time is prolonged. Further, when the rubber sheet is used as a cushioning material, since the molding temperature is limited to 150 ° C, it is not possible to use a large hot plate to form a material having a high molding temperature with high precision. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a press apparatus and a press apparatus system capable of suppressing a decrease in accuracy in a thickness direction of a product even when a large hot plate is employed. And a stamping device and a stamping device system that do not extend the forming time. In order to solve the above problems, the press device of the present invention includes a pair of hot plates; a hot plate spacing holding mechanism that fixes one of the pair of hot plates to another one at a predetermined interval; metal a plate fixed to the at least one hot plate according to a surface covering the workpiece side; a heat transfer medium filled in the gap portion of the at least one hot plate and the metal plate; and a temperature control mechanism a temperature control mechanism controls a temperature of the hot plate; and a heat transfer medium pressure adjusting mechanism that adjusts the heat transfer when the distance between the pair of hot plates is maintained according to a predetermined pitch by the hot plate spacing holding mechanism The pressure of the medium applies a pressing force to the workpiece disposed between the pair of hot plates. Therefore, according to the stamping apparatus of the present invention, the pressure of the heat transfer medium is adjusted by the heat medium pressure adjusting mechanism, and the metal plate mounted on one hot plate is maintained in a planar shape, and the other hot plate is aligned and subjected to Press. In this case, since the flatness accuracy of the metal plate depends only on the surface roughness thereof, the surface roughness of the metal plate is suppressed to a low level by mirror processing or the like, whereby the workpiece can be kept hot-pressed at a high level. The flatness accuracy of the 7 1376306 metal plate at the moment. In addition, a vacuum seal may be attached to the at least one hot plate, and the vacuum seal seals the gap between the pair of hot plates when the workpiece is pressed, and the outer portion of the workpiece is empty relative to the outside air. 'Between the seals. In addition, vacuum may be included, which reduces the air pressure in the space around the workpiece when the workpiece is pressed. If the crucible is configured in this way, it is necessary to press in a decompressed state. Since the decompression is only a space between a pair of hot plates, the pressure around the workpiece can be reduced to a desired amount in a short time. Air pressure. Further, the stamping apparatus system of the present invention includes a first punching device that heats the workpiece at a predetermined temperature, and a second punching device that is hot-pressed by the workpiece heated by the first punching device; 1 'The belt conveyor places the above workpiece on the metal belt ^, and presses 1! The system is sent to the second tree. The system is constructed in accordance with the first and first stamping devices described above, together with the belt. According to such a scouring device system, since the metal belt is used, it is not necessary to hide the workpiece transport mechanism from the punching device to shorten the pressing time. In addition, since the belt is ====, the heat from the hot plate is still not: see even in the case of a large hot plate.

The batch stamping system 1 includes a preheat stamping apparatus, a heated stamping apparatus 200, and a cooling stamping apparatus 300. The product P (in the present embodiment, a 1C card) formed by a resin, a magazine, etc., is conveyed from the left side to the right side by the transfer of 40 〇, and is heated by a preheating press apparatus 1〇〇. The apparatus 200, the cooling press apparatus 3 is sequentially pressed to form a product having a desired shape and physical properties, that is, the temperature of the product p is raised to a predetermined temperature by the preheating press apparatus 100, and then heated by the heating press apparatus 200. Tightly, it is cooled to a normal temperature by the cooling press apparatus 3, and the pressing is performed by bringing the movable disk provided above the fixed disk into contact with the fixed disk. The belt conveyor 400 includes a pair of rollers 401L, 401R disposed upstream and downstream of the three stamping devices 1A, 3, and a circulating steel strip 403 that is bridged over the rollers. The roller 401L is rotationally driven in the clockwise direction in the first figure by the motor 409, and the steel belt 403 is driven in conjunction with the rotation of the roller. For example, the tip end of the steel strip 403 shown in the first figure is disposed between the movable disk portions η 〇, 21 〇, 31 各 of the respective press devices 100 to 300 and the fixed disk portions 120, 220, and 320. Further, the belt lifters 405 and 407 for raising and lowering the tip end of the steel strip 403 are provided on the belt conveyor 400. The belt floaters 405, 407 change the position of the top end of the steel strip 403 in the vertical direction according to the following manner: the steel strip 403 takes the top end of the steel strip 403 and places it on the fixed discs #12(), 22〇, 320. The upper pressable state (solid line in the first figure), any one of the transportable state (dotted line in the 'first figure) of the top end of the steel strip 3 relative to the fixed disc portions 120, 220, 320 status. 1376306 ^The first figure shows that the belt upper damper 4〇5 is disposed on the upstream side of the preheating stamping apparatus 100, and the belt levee 407 is disposed on the downstream side of the cooling ram apparatus 300. The three belt levator 405 includes a shaft 4 around the shaft 4 〇5S swinging rod

405L' and the roller 4〇5R attached to the front end of the rod 4〇5L. The roller 4〇5R is in contact with the top end of the steel strip 403 from below. In addition, the winding wheel 4 511 is accompanied by the steel belt 403 405L driven by a driving mechanism (gas cylinder, solenoid #) not shown in the drawing, and the top end of the roller 405R is substantially the same as the fixed disk portion 丨2〇, 220, 320 a first state in which the top surfaces are substantially equal (solid lines in the first drawing), and a second state in which the top end of the roller 405R is located higher than the top surface of the fixed disk portions 12, 22, 32 The state of any of the dashed lines in a figure. The belt lifter 407 also includes a rod 407L having the same function as the belt lifter 405, a shaft 407S, and a roller 407R. That is, when the belt upper floaters 405 and 407 are in the first state, the steel strip 403 is in a depressible state, and when the belt upper floaters 405 and 407 are in the second state, the steel strip 403 is in a transportable state. On the top end of the steel strip 403, the product ρβ is placed while transporting the product p between any of the movable disk portions 11〇, 210, 310 of the respective punching devices 100 to 300 and the fixed disk portions 120, 220, 320. The belt floater is driven in accordance with the manner in which the floaters 405 and 407 are in the first state, so that the steel strip 403 is in a transportable state. In this state, the motor 409 is driven to transport the product ρ between the movable disk portion of the desired press device and the fixed disk portion. In this state, since the steel strip 403 is not in contact with each of the press apparatuses 1 to 300, the steel strip 403 is prevented from being damaged by the contact, or the steel strip 403 is applied to each of the press apparatuses 1 to 3, and 1376306. The frictional resistance between the two hinders the transportation of the product P. After the product p is transported to the desired position, the belts 403 and 407 are driven in the first state, so that the steel strip 403 is in a state of being pressed. If the steel strip 403 is in a position where it can be pressed, the lamp places the steel strip 403 on the fixed disk portion, so that the product P can be pressed between the movable disk portion and the second disk portion. * 疋 In addition, the movable disk sections 110, 210, and 310 are connected, and they are simultaneously raised/lowered. Further, the interval between the preheating rushing device 100 and the heating house device 2 以及 and the door pS of the heated press device 200 and the cooling press device 3 are equal (hereinafter referred to as L). Thus, during the period in which the product is cooled by the cooling press 300, the other product is preheated and/or heat-pressed, so-called series pressing. The structure of the heating press apparatus 200 will be described with reference to the second drawing. Further, the preheating press device 100 and the hot press device 2 have the same structure. The second drawing is an external shape view showing the structure of the heating press apparatus 200. In the second drawing, a cross-sectional view of the A-a line of the heating press apparatus 2 (refer to the first drawing) and a block diagram of various apparatuses used for performing various operations of the heating press apparatus 200 are shown. The heated press device 2 includes a top hot plate portion 21A that presses the holder 203 as a movable disk portion, a bottom hot plate portion 220 as a fixed disk portion, and a cylinder portion 230. The pressing bracket 203 is rigidly supported on the bottom of the press device setting portion. The fixing disk 221 of the bottom hot plate portion 22 is fixed to the bottom portion 2 313 of the pressing holder 2〇3. Further, the cylinder portion 230 is fixed to the bottom surface of the top portion 203a of the pressing bracket 203. The cylinder portion 230 includes a cylinder block 231, a piston 232 that is movable up and down while sliding with the inner wall 1376306 of the cylinder block 231, and a rod 233 that extends vertically downward from the bottom portion of the bottom surface of the piston 232. In the middle of the bottom surface of the cylinder block 231, a through hole 231a is opened, and the rod 233 slides with respect to the through hole 231a as the piston 232 moves up and down, and moves up and down. At the bottom end of the rod 233, a movable disk 211 of the top hot plate portion 210 is fixed.

The hollow portion 234 of the cylinder block 231 is partitioned into a hollow portion (upper) 234a and a t-empty portion (lower) 23 by a piston 232'. The hollow portion (upper) 234a and the hollow portion (lower) 234b are filled with hydraulic oil, respectively. The operation of the piston 232 (i.e., the vertical movement of the top hot plate portion 210) is performed by the hydraulic element 260 controlling the hydraulic oil. The structure of the hydraulic member 260 will be described below. The third diagram shows the hydraulic element 260 and the cylinder block 230 in a voiced manner. For example, as shown in the third figure, the hollow portion (upper) 234a of the cylinder 231 is connected to the tube 262, and the middle portion (lower) 234b is connected to the tube 263. The other ends of the tubes 262 and 263 are connected to the square two; the knife switching valve SV3. Further, on the direction switching valve SV3, a pipe 261 whose one end is connected to the pump 266 and a pipe 264ct which is open at one end are connected to the direction switching valve sv\

Corresponding to the operation from the outside, the "connection pipes 261 and 262, and the state of the connection pipes 263 and 264C", and the "connection pipes 261 and 263, and the state of the connection pipes 262 and 264c," are switched. The pump 266 is from the fuel tank. 265 sucks up the hydraulic oil and sends it to the pipe 261. In the case where the direction switching valve SV3 * "connects f 261 * mud and the connection pipe is added", the pump 266 sends the hydraulic oil to the oil red body and says On the other hand, the hollow portion (the hydraulic oil of the lower part) is discharged by the check valve RV3. In addition, the discharge mechanism of the oil of the hollow portion (lower) 234b will be described later. 12 1376306 In addition, When the direction switching valve SV3 takes "the connection pipes 261 and 263 and the state of the connection pipes 262 and 264c", the pump 266 sends the hydraulic oil to the hollow portion (lower) 234b of the cylinder block 231, and on the other hand, the hollow portion ( The hydraulic oil of the upper portion 234a is discharged through the tube 264b and the guide check ring RV2. The "discharge mechanism for the hydraulic oil of the t-empty portion (upper) 234a will be described later. The direction of the tube 262 and the tube 263 is switched. In the vicinity of the valve SV3, a check valve TV is respectively provided 1 and TV 2. The check valves TV1 and TV2 restrict the flow of the hydraulic oil flowing in the tube 262 and the official 263 only in the direction from the direction switching valve SV3' toward the oil rainbow 231, preventing the backflow of the liquid oil. In principle, 'the hydraulic oil does not switch from the direction switch valve SV3 to the flow tube 264c. Further, on the tube 262 and the tube 263, the tubes 264b and 264a are respectively provided according to the manner in which the branch is formed. On the tubes 264b and 264a, The pilot check valves RV2 and RV3 are respectively connected. RV2 and RV3 respectively operate when the cylinder rises and falls, and discharges the hydraulic oil passing therethrough to operate the cylinder. That is, the pump 266 sends the hydraulic oil to the hollow portion of the cylinder block 231 (on When the internal pressure of the pipe 262 rises to a predetermined value or more, the pilot check valve RV3 is opened, and the hydraulic oil of the hollow portion (lower) 234b is discharged, and the cylinder block is lowered. Similarly, if the pump 266 sends the hydraulic oil to the cylinder In the hollow portion (lower portion) 234b of the body 231, when the internal pressure of the tube 263 rises to a predetermined value or more, the pilot check valve RV2 is opened, and the hydraulic oil of the hollow portion (lower) 234b is discharged, and the cylinder block is raised. If in this embodiment, When the hydraulic oil is sent to one hollow portion of the cylinder block 231, the hydraulic oil in the other hollow portion is discharged from the hollow portion. Thus, according to the present embodiment, the pump 266 and the direction switching valve SV3 are controlled, thereby being freely available. The piston 232 and the movable plate 211 13 1376306 are moved up and down. The structure of the top hot plate portion 210 and the bottom hot plate portion 220 will be described below with reference to the second figure. The top hot plate portion 210 allows the top hot plate 213 to pass. The heat insulating material 212 is fixed in such a manner as to be suspended from the bottom surface of the movable disk 211. Similarly, the bottom hot plate 223 in the bottom hot plate portion 220 is fixed to the top surface of the fixed plate 221 by the heat insulating material 222. Further, on the top surface of the bottom hot plate 223 in the bottom hot plate portion 220, a metal buffer member 280 (which will be described later) is fixed. Further, a vacuum seal mounting plate 214 is fixed to the bottom surface of the top hot plate 213 ® of the top hot plate portion 210. The vacuum seal mounting plate 214 is a highly thermally conductive metal plate, and the heat of the top hot plate 213 is quickly moved in the vacuum seal mounting plate 214. That is, the vacuum seal mounting plate 214 has a function as a hot plate protection plate for preventing contact between the product P and the top hot plate 213. The hydraulic oil element 260 is driven to drive the top hot plate portion 210 downward, whereby the product P placed on the steel strip 403 can be sandwiched between the metal buffer member 280 and the vacuum seal mounting plate 214 of the top hot plate portion 210. , press it. Further, the spacer bar 270 is elongated vertically upward from the end portion of the top surface of the bottom hot plate 223 (the left and right ends in the second ® figure). If the top hot plate 213 is lowered, the top end of the spacer bar 270 comes into contact with the bottom surface of the top hot plate 213, and the top hot plate cannot be further lowered. Thus, the spacer lever 270 serves as a guide for keeping the interval between the upper and lower hot plates at the time of pressing constant and keeping the bottom surface of the vacuum seal mounting plate 214 horizontal. Further, during the pressing of the product P, the top hot plate 213 of the top hot plate portion 210 and the bottom hot plate 223 of the bottom hot plate portion 220 are heated by the heating system 240 to the forming temperature of the product P, respectively. Further, a method of adjusting the temperature of the hot plate by the heating system 14 1376306 will be described later. For example, the product P is pressed while being heated, and the so-called hot pressing step is performed to form the product P. In the case where the product p includes a thermoplastic resin, the product p is formed by performing a cooling and pressurizing step to be described later after the heating press of the heated press device 2 is performed. The structure of the heating system 240 will be described with reference to the second figure. The heating system 240 includes a pump 241 that circulates heat transfer medium oil inside a heating heat transfer medium line formed inside the top luke tray 213 and the bottom hot plate 223; heating the heat transfer medium oil Heating element 242. Further, the pump 241, the top hot plate 213 and the bottom hot plate 223, and the heating element 242 pass through the heating heat transfer medium pipe 244 to form a heat transfer medium passage. The pump 241 feeds the heat transfer medium to the heat transfer medium inlet of the heat transfer medium line for heating. The temperature of the top hot plate 213 and the bottom hot plate 223 is adjusted by the heat transfer medium. The heat transfer medium oil sent from the top hot plate 213 and the bottom hot plate 223 passes through the heating heat transfer medium pipe 244 and flows to the heating element 242. m The heating element 242 is a device that heats the heat transfer medium oil passing through it through a heater. The temperature of the heater is controlled by the control of the semiconductor switching element, whereby the temperature of the heat transfer medium oil can be controlled. Further, the heat transfer medium oil sent from the heating element 242 is sent to the pump 241 through the screen ', and flows again to the top hot plate 213 and the bottom hot plate 223. The fourth drawing is a cross-sectional view in which the bottom hot plate 223 of the bottom hot plate portion 22 is cut in the horizontal direction. • The bottom hot plate 223 is a substantially square steel plate. In the bottom hot plate 223, first engravings 2231 a to h of eight 15 1376306 through holes which are parallel to each other in the up and down direction in the fourth drawing are formed (in order from the hole on the left side in the fourth figure) 'referred to as 223la, 2231b, 2231c, 2231d, 2231e, 2231f, 2231g, 223lh), in the bottom end portion of the fourth figure of the bottom hot plate 223, in a manner perpendicular to all of the first holes 2231a to h2, a second ceremony 2232 opened along the left-right direction in the fourth figure; in a manner perpendicular to the first holes 223la to f from the left side of the top end portion in the fourth figure of the bottom hot plate 223, along the fourth figure a third hole 2233 opened in the left-right direction; in the left-right direction in the fourth figure, in a manner perpendicular to the first holes 223g1 and 223ih from the right side of the top end portion in the fourth figure of the bottom hot plate 223 The fourth hole 2234. A cover 2236 is fitted to both ends of the first holes 2231b to g, respectively. The cover 2236 is embedded in the first holes 2231a and 223.1 h.' only at the tip end portion of the fourth figure. In addition, at both ends of the second hole 2232, a portion between the first holes 2231a and 223, and a portion between the first holes 2231c and 223ld, a portion between the first holes 223le and 223If, and a portion A portion between one of the holes 223ig and 223lh is embedded in the cover 2236. Further, a portion between the first hole 2231b and 2231c and a portion between the first hole 2231b and 2231c and the portion between the first hole 223id and 2231e are fitted into the cover 2236 at the left end in the third hole 2233, respectively. Further, at the right end of the fourth aperture Μ%, the cover 2236 is embedded. In the corresponding holes of the first holes 2231a to h, the second holes 2232, the third 2233 and the fourth holes 2234, for example, the disk 2236 is immersed in the above-described manner. Thus, the first holes 2231 a to h, the second holes 2232, the first holes 2233 and the fourth holes 2234 are at the bottom end 2238 of the fourth hole of the first hole 2231a and the third hole of the first hole 2231h. The bottom end 2239 is a two-end end, and is heated by a heating heat transfer circuit extending inside the bottom hot plate 223. *, , , 5 In the heat transfer medium line for heating, the heat transfer medium oil heated by the heating system 24〇 (second 16 1376306) is circulated, and the bottom heat plate 223 is punched through the heat transfer medium oil. heating. Further, in the bottom hot plate 223, a temperature sensor which is not shown in the figure is attached. The temperature sensor is connected to a controller (not shown) in the heated stamping device 200. When the heated stamping device 200 heats the product P, the top hot plate 213 is determined according to the temperature sensor. The temperature is about 3 degrees of the heating forming temperature, and the controller controls the heating system 240 to adjust the temperature of the heat transfer medium oil flowing through the piping. In addition, in the present embodiment, the heat transfer medium oil subjected to the temperature control is circulated inside the hot plate, thereby adjusting the temperature of the hot plate, but the hot plate can also be used according to the heater embedded in the hot plate. It is constructed by heating. The fifth view is a vertical sectional view of the metal buffer member 280. As shown in Fig. 5, the metal cushioning member 28 includes a thick plate-shaped plate member 281 having a concave portion 281H formed at an intermediate portion of the top surface, and a stainless steel metal plate 282 covering the concave portion 281H. When there is no gap, the end portions of the plate member 281 and the metal plate 282 are integrally welded, whereby the metal buffer member 280 is formed in accordance with the plate member 281 and the metal plate 282. On the bottom surface of the plate member 281, a plurality of screw holes 281B which are vertically opened upward are formed (in the fifth figure, only one of them is shown). Cutting the splicing thread in each hole of the threaded hole 281B so that the shackle 283 passing through the through hole 2237 which is vertically opened on the side of the bottom hot plate 223 is screwed with the thread, thereby, the metal is The cushioning member 280 is fastened to the bottom hot plate 223. A gap portion 284 is formed between the concave portion 281H of the plate portion 281 and the metal plate 282. The gap portion 284 communicates with the heat transfer medium passage 285 for pressurization. The other end of the pressurizing heat transfer medium passage 285 is connected to the pressurizing controller 250 17 1376306. Further, the gap portion 284 and the heat transfer medium passage 285 for pressurization are filled with heat transfer medium oil. When the heat transfer medium oil filled in the gap portion 284 and the pressure heat transfer medium passage 285 absorbs the heat of the plate portion 281, the heat is discharged to the metal plate 282. Since the fluid medium heat transfer medium oil is interposed between the metal plate 282 and the plate portion 281, the metal plate 282 is quickly heated. The pressurization controller 250 is connected to a controller not shown in the drawing in the heating press device 200. The controller can control the pressurizing controller 25A to change the filling portion 284 and the heat transfer medium for pressurization. The pressure of the heat transfer medium oil in passage 285. The specific structure of the pressurizing controller 25A will be described later. The top surface of the metal 282 is mirror finished, and its surface roughness is in the range of several micrometers. Then, if the balance metal plate 282 that maintains the pressing pressure and the pressure of the heat transfer medium oil filled in the gap portion 284 and the pressure heat transfer medium passage 285 is maintained in a planar state, the flatness accuracy of the bottom surface of the metal plate 282 is maintained. Within 10 microns. Further, the upper and lower surfaces of the steel strip 4〇3 (first drawing) are mirror-finished, and the surface roughness thereof is in the range of several micrometers. Further, on the product p, a sheet B which is not recorded in steel is placed. Here, the sheet B is also subjected to mirror finishing. Since the distortion of the page of the bottom hot plate 223 is absorbed by the metal buffer member 28, if the bottom hot plate portion 22 is brought close to the top hot plate portion, the steel strip 4〇3 is maintained in a flat state with high precision. , the product p is lost between it and the sheet B t . Further, in the top hot plate 213, a heat transfer medium line for pressurization which is the same as the official path of the bottom hot plate 223 is formed, and the top hot plate 213 is quickly heated. ^ On the peripheral portion of the bottom surface of the vacuum seal mounting plate 214, the vacuum seal 219 is fastened by means of a thread 1376306. The vacuum seal 219 is disposed around the periphery of the vacuum seal mounting plate 214. If the vacuum seal mounting plate 214 is brought close to the metal buffer member 280, the gap between the vacuum seal mounting plate 214 and the metal buffer member 280 passes through the vacuum seal. 219 and sealed. An opening 214a (second diagram) communicating with the vacuum pump 290 is formed on the bottom surface of the vacuum seal mounting plate 214. Thus, if the gap between the vacuum seal mounting plate 214 and the metal buffer member 280 is sealed by the vacuum seal 219, the vacuum pump 290 is driven to reduce the pressure around the article P. The structure of the cooling press apparatus 300 is basically the same as that of the heating press apparatus 200, but the heat transfer medium flowing through the hot plate is cooled water, and by circulating it, the hot plate is cooled. The structure of the pressurization controller 250 will be described below with reference to the sixth drawing. The sixth diagram is a block diagram showing the structure of the pressurization controller 250 in a schematic manner. The heating controller 250 includes a first hydraulic cylinder 25, a second hydraulic cylinder 252, a pump 259a that supplies hydraulic oil to the second hydraulic cylinder 252, a tank 259b that supplies hydraulic oil to the pump 259a, and a direction switching valve SV5. The first hydraulic cylinder 251 includes a sleeve 251a, a piston 251b, and a rod 251c. The piston 251b is a member slidably attached to the inner surface of the sleeve 251a. The rod 251c is fixed in such a manner as to extend from the one side of the piston 251b in the axial direction of the sleeve 251a (i.e., the direction of movement of the piston 251b, the rightward direction in the sixth drawing), and the end portion 251d protrudes from the sleeve 251a. The internal space of the sleeve 251a is divided by the piston 251b into a front space 251e (left side in the sixth drawing) and a rear space 251f (right side in the sixth drawing). The front space 251e of the first hydraulic cylinder 251 is filled with a heat transfer medium oil, and the front space 251e is connected to the pressurization medium 19 376306 formed in the metal buffer 280 through a pipe 254. Further, the rear space 251f of the first hydraulic cylinder 251 is in an atmospheric pressure state. Then, by the force f, the rod 251c is pressed into the moon il space 251e'. Accordingly, the pressure P1 of the heat medium oil in the front space 251e is F/A1 (A1: the cross-sectional area of the piston 251b). Then, by controlling the force F, the pressure of the heat transfer medium oil filled between the metal plate 282 and the plate portion 281 can be controlled. Thus, the heat transfer medium oil for pressurizing the metal plate 282 is filled only between the metal plate 282 and the plate portion 281, and into the piping in the front space 251e of the first hydraulic cylinder 251. Thus, even in the case where the metal plate 282 is broken, the outflowing heat transfer medium oil is still small. Further, in the case where the heat transfer medium oil thermally expands, the piston 251b moves in accordance with the volume value in which the rear space 251f expands, whereby the pressure of the heat transfer medium oil can be maintained without using the relief valve. On the other hand, the second hydraulic cylinder 252 includes a sleeve 252a filled with heat transfer medium oil, a piston 252b, a rod 252c, a forward limit sensor 252g, and a back limit sensor 252h. The piston 252b is a member slidably attached to the inner surface of the φ sleeve 252a. Further, the rod 252c is fixed in such a manner as to extend from the one side of the piston 252b in the axial direction of the sleeve 252a (i.e., the direction of movement of the piston 252b, the leftward direction in the sixth drawing), and the end portion 252d protrudes from the sleeve 252a. . The inner space of the sleeve 252a is partitioned by the piston 252b into a front space 252f (left side in the sixth drawing) and a rear space 252e (right side in the sixth drawing). The heat transfer medium oil is filled in both the front space 252f and the rear space 252e. The rod 252c can be driven axially along the 20 1376306 axial direction of the sleeve 252a by controlling the pressure of the heat transfer medium oil injected into the front space 252f and the rear space 252e. The end portion 251d of the rod 25lc of the first hydraulic cylinder 251 is connected to the end portion 252d of the rod 252c of the second hydraulic cylinder 252 via the connecting member 253. Thus, the front portion can be controlled by controlling the driving force of the driving rod 252c. The pressure P1 of the heat transfer medium oil in the space 2Me. In the present embodiment, when any of the front space 252f, the rear space 252e is pressurized, the other pressure is atmospheric pressure, and a detailed description thereof will be described later. Then, when φ drives the rod 251c in the direction from the rear space 252e toward the front space 252f (to the left in the drawing), the driving force is the pressure p2 of the heat medium oil filled in the rear space 252e and The value of the product of the cross-sectional area a2 of the piston 252b. That is, the pressure pl of the heat transfer medium oil in the front space 251e is Ρ2χΑ2/Α1. Thus, by changing the sectional area A2 of the piston 252b of the second hydraulic cylinder 252, the pressure pi of the heat transfer medium oil, that is, the range of the pressure for pressurizing the metal plate 282 can be changed. The forward limit sensor 252g and the back limit sensor 252h are sensors that detect whether the piston 252b is in the corresponding mounting position. In the present embodiment, the piston 252b is controlled in accordance with the manner between the forward limit sensor 252g and the backward limit sensor 252h*. The position control method using the forward limit sensor 25 2g and the back limit sensor 25 2h will be described later. The method of controlling the driving force of the drive lever 252c will be described below. The direction switching valve SV5 is a 4-turn switching valve having a first 埠P1' second 埠P2, a third 埠P3, and a third 牟P4.

Then, 'the heat transfer medium sent from the pump 259a when the setting of the direction switching valve SV5 is "pi and P3 are turned on, and P2 and P4 are turned on" The oil passes through the tube 255 to the front space 252f of the sleeve 252a of the second hydraulic cylinder 252. On the other hand, the rear space 252e of the sleeve 252a of the second hydraulic cylinder 252 is connected to the tube 258. As a result, The piston 252b of the second hydraulic cylinder 252 moves toward the rear space 252e (to the right in the sixth drawing), and a part of the heat medium oil in the rear space 252e is discharged through the pipe 258. In addition, the setting of the direction switching valve SV5 At "P1 and P4 are on, and P2 and P3 are on In the state of the heat transfer medium, the heat transfer medium oil sent from the pump 259a flows through the pipe 256 to the rear space 252e of the sleeve 252a of the second hydraulic cylinder 252. On the other hand, the front space 252f is connected to the pipe 258. The piston 252b moves toward the front space 252f (leftward direction in the sixth drawing), and a part of the heat medium oil in the front space 252f is discharged through the pipe 258. The switching operation of the direction switching valve SV5 is performed by the pressurizing controller Controlled by 250 (not shown). On the tube 256, an electromagnetic spill valve RV4 is provided. The electromagnetic spill valve RV4 is controlled by the pressurization controller 250 according to the heat transfer medium oil in the tube 256. The pressure is controlled to a predetermined pressure to perform a valve opening and closing operation. Since the pressure of the heat medium oil filled between the metal plate 282 and the plate portion 281 is the same as the pressure of the heat medium oil in the tube 256, 22 ^306 Controlling the opening and closing of the electromagnetic spill valve RV4, the pressure of the heat transfer medium oil filled between the metal plate 282 and the plate portion 281 can be controlled within a required range. In addition, the electromagnetic overflow wide RV4 is opened and closed. Pressure set on tube 254 a detector ΚΠ, or a pressure sensor disposed in a tube condition; = ^ performs feedback control. As described above, in the present embodiment, the following scheme is employed, in which two hydraulic cylinders are connected in series to drive the same a rod of a hydraulic cylinder, thereby adjusting the pressure of the heat transfer medium oil filled in the other hydraulic cylinder. That is, the heat transfer medium oil is not directly pressurized through the pump. Thus, even at temperature In the case where the heat transfer medium oil cannot be directly pressurized by the pump due to conditions or the like, according to the embodiment of the present embodiment, the heat transfer medium oil can be pressurized according to the required pressure. Further, the detection results of the forward limit sensor 252g and the back limit sensor 252h are controlled in such a manner that the piston 252b of the second oil cylinder 252 is normally positioned by the control of the gather. Between the limit sensor 252g and the back limit sensor 252h. That is, φ stops the pump when the forward limit sensor 252g or the back limit sensor 252h detects the piston 252b. Over the valves 255 and 256, relief valves RV5 and RV6 are provided, respectively. When the internal pressures of f 255 and 256 reach a predetermined value, the relief valves RV5 and RV6 are opened, and the heat transfer medium oil is discharged to the outside of the tube, and the internal pressures of the tubes 255 and 256 are suppressed to a predetermined value or less. Throttle valves TV3 and TV4 are provided in the vicinity of 埠P3 and P4 of the officers 255 and 256, respectively. The throttle valves TV3 and TV4 control the flow rate of the heat transfer medium oil flowing through the tubes 5 and ^, and control the speed of the movements 23 1376306 of the cylinder blocks 512 and 522.
