Description

Continuous stamping device

The present invention relates to a continuous press apparatus which continuously presses a sheet-like material such as a prepreg and continuously forms a workpiece having the same cross-sectional shape.

A structural material in which a semi-cured film is laminated, in particular, a carbon fiber is used as a reinforcing material for a semi-cured film, which is lightweight, rigid, and high in strength, and is used in aerospace applications (for example, a bundle of reinforcing aircraft tails, etc.) ). In particular, for aerospace applications, the same cross-sectional shape of 10 meters in the longitudinal direction is used. In order to shape the member (work to be processed) as described above, an intermittent press device such as that disclosed in JP-A-61-242816 is used.

The intermittent press device disclosed in Japanese Laid-Open Patent Publication No. SHO 61-242816 has a hot plate pair that is controlled to be periodically opened and closed, and a transfer mechanism that transfers the workpiece. That is, when the hot plate pair is opened, the unformed portion of the elongated strip-shaped workpiece is fed between the pair of predetermined hot plates. Next, the hot plate pair is closed, and a portion of the long strip-shaped workpiece among the hot plate pairs is hot stamped. Next, the hot plate pair is opened, and the formed portion is sent out between the pair of hot plates, and the unformed portion is continuously fed between the pair of hot plates. By continuing the process, the elongated strip-shaped members of the same cross-sectional shape are formed.

As described above, the intermittent press device has the following problems. First, since it is necessary to perform a thermoplastic resin by a pair of hot plate pairs. Heating, forming, and cooling. If it is a thermosetting resin, it is heated, formed, and thermally cured. Therefore, the workpiece is heated and heated from normal temperature and normal pressure. Therefore, the semi-cured film is locally heated to a glass transfer temperature or the like and flows. Then, due to the flow of the resin, there are defects in the disorder of the fiber, the flow of the resin, the whitening of the void, and the uneven thickness due to the flow of the resin, and the second, at the end of the hot plate. In the part, the difference in the thickness direction is generated between the portion before the forming of the workpiece and the portion in the forming, which affects the strength of the product. That is, the step is also a disadvantage.

In order to prevent the above-mentioned disadvantages, the intermittent press device disclosed in Japanese Laid-Open Patent Publication No. SHO 61-242816 is to be placed in the direction in which the workpiece is fed, and the press surface is inclined or stepwise (i.e., stepped), and will be fed. The interval between the side punch faces is larger than the feed side. The workpiece is first adjusted in shape on the feed side, and then hot stamped on the feed side. On the delivery side, the hot plate spacing is increased, so the resin does not easily flow.

However, in this mode, the hot plate is heated to a temperature sufficiently higher than the glass transition temperature of the workpiece, so that the flow of the resin cannot be completely prevented. Moreover, when a step is set in the hot plate, there is a possibility that a step is formed in the workpiece after the forming.

The present invention has been developed in view of the above problems. That is, an object of the present invention is to provide a continuous press apparatus which can manufacture a length product without causing defects in the workpiece during molding.

In order to achieve the above object, the continuous stamping apparatus of the present invention has a flat upper heat plate formed on the lower surface, opposite to the lower surface of the upper hot plate, and a flat lower heat plate formed on the upper and lower heat plates. Separately defining a first region and a second region away from the first region in a direction of the hot plate; heating the first region of the two hot plates to the first region a first heating mechanism of a temperature; a second heating mechanism for heating the second region of the two hot plates to a second temperature higher than the first temperature; driving at least one of the upper and lower hot plates to be placed under pressure a pressing mechanism for the workpiece between the two hot plates; and a workpiece conveying mechanism that transfers the workpiece to be hot-pressed by the two hot plates to the conveying direction from the first region to the second region.

In the case of the above configuration, the shape of the workpiece is adjusted by pressing at a low temperature in the first region, and then the workpiece is conveyed to the second region and hot-rolled at a high temperature. Therefore, it is possible to prevent defects caused by the rapid heating of the workpiece. Further, in the present invention, since the shape of the workpiece is adjusted by forming a flat pair of hot plates on the surface abutting on the workpiece, and the hot stamping is performed, the line-shaped defect does not occur.

Moreover, the present invention further has a hot plate spacing establishing mechanism for determining the interval between the upper hot plate and the lower hot plate when the workpiece is pressed, and the hot plate spacing determining mechanism is opposite to the first area and the The second area constitutes a different hot plate spacing. According to the above configuration, the thickness and load of the workpiece can be changed in the first region and the second region. For example, by increasing the interval between the hot plates in the first region, the load applied to the workpiece can be reduced, and the interval between the hot plates can be reduced in the second region, and a large load can be applied to the workpiece. Further, when the workpiece is reacted during the hot stamping process and the material which shrinks or expands is used, the desired thickness of the workpiece can be finally obtained by adjusting the hot plate interval of each region to the extent of shrinkage or expansion. . For example, when a material which is shrunk in the hot stamping process is used as a workpiece, the interval between the hot plates in the second region is further reduced, and hot pressing is performed at a desired load and thickness.

Further, the hot plate spacing determining mechanism is disposed on the pair of the upper hot plate side and the lower hot plate side, and the distance rod and the lower portion on the upper hot plate side The distance rod on the hot plate side abuts, and the interval between the upper hot plate and the lower hot plate is determined, and the pair of the distance bars is at least one pair between the first region and the second region.

Moreover, the first pressing portion for pressing the workpiece disposed in the first region and the second pressing portion for pressing the workpiece disposed in the second region may be provided The composition of the pushing mechanism. Thereby, the first pressing portion drives the hot plate with a low load that can sufficiently press the workpiece in the first region, and pushes both the first and second regions with a single pressing portion. The device can reduce the loss of power.

Here, the first temperature system is substantially equal to the glass transition temperature of the workpiece. Further, the second temperature system is substantially equal to the forming temperature of the workpiece. When the workpiece is a thermosetting resin, the molding temperature is set to, for example, a hardening temperature region of the thermosetting resin.

Moreover, the workpiece conveying mechanism may be configured to move the workpiece when the first and second pressing mechanisms do not press the workpiece. For example, the workpiece conveyance mechanism has a lower endless belt which is hung on a pair of pulleys having a pair of pulleys below, and is placed on the workpiece; the upper endless belt has a cross-hook a pair of upper pulleys on the pulley, configured to be opposed to the lower endless belt through the workpiece; and an endless belt driving mechanism for driving the upper endless belt and the lower endless belt, the lower side endless belt upper side portion and the foregoing The lower side portion of the upper endless belt is disposed between the upper and lower hot plates, and the workpiece is conveyed in a state of being held on the lower side portion of the lower endless belt and the lower side portion of the upper endless belt, and is conveyed by the upper portion. And the lower hot plate presses the upper side portion of each of the aforementioned lower side endless belts and the lower side portion of the aforementioned upper side endless belt. Further, the endless belt drive mechanism has a gripper that can hold the workpiece through, for example, the upper and lower endless belts, and the gripper driving mechanism. The gripper is reciprocated in a direction opposite to the transport direction and the transport direction. Further, the gripper drive mechanism reciprocates the gripper by, for example, a cylinder mechanism. Further, the gripper is disposed on either the transport direction side or the retreating direction side with respect to, for example, the upper and lower hot plates.

Moreover, one of the pulleys of the lower pulley pair is biased in a direction separating from the other, and one of the pulleys of the upper pulley pair is biased in a direction separating from the other. Thereby, tension can be imparted to the endless belt. Further, one of the pulleys of the lower pulley pair is opposite to the other, and can support a slight movement in the conveying direction and the retreating direction, and one of the pulleys of the upper pulley pair is opposite to the other, and can support the conveying direction and the backward direction to be minute. The movement. In this configuration, since one of the endless belts is disposed between the hot plates, the upper hot plate is stretched when it is close to the lower hot plate. In this configuration, by one of the pair of minutely movable pulleys, the endless belt is relieved of excessive tension generated when the hot plate is stretched, and the belt is prevented from being broken.

Further, the endless belt is a metal belt such as steel. Alternatively, it may be a resin tape formed of a heat resistant resin (polyimine).

Further, it is also possible to have a structure with a biasing mechanism for biasing the portions between the upper end endless belt and the lower end endless belt upper portion hot plate and the lower hot plate to be in close proximity to each other. According to the above configuration, when the workpiece is pressed by the hot plate, the endless belt can be separated from the hot plate. Further, the pressing mechanism of the upper and lower hot plates may be pressed by the pressing mechanism, and after the two hot plates are separated from each other, the upper and lower endless belts are kept in contact with the workpiece for a predetermined period of time. Then, the upper side and the lower side endless belt are pressed to make at least one of the two endless belts slowly separated from the workpiece. According to the above configuration, when the hot plate is opened, the endless belt does not suddenly bounce and damage the product.

Also, for example, the endless belt biasing mechanism has a pair of upper side biasing The roller is disposed on the upstream side of the upper hot plate and is disposed on the downstream side, and is configured to press the lower side portion of the upper end from the upper side and rotate with the upper end endless belt; and a pair of lower side elastic rollers are disposed at the lower part of the heat The upstream side of both sides of the disk and the downstream side are configured to press the upper side portion of the lower endless belt from the lower side, and rotate with the lower end endless belt.

Further, in the upper and lower hot plates, a third region may be formed on the side of the transport direction than the second region, and a third heating mechanism for heating the third region of the two hot plates to the third temperature may be provided. The workpiece conveyance mechanism is configured to convey the workpiece from the second region to the third region. According to the above configuration, the hot stamping can be carried out twice, and it is not necessary to lengthen the pressing time of the workpiece in the first region, and it is possible to lengthen the time spent on the hot stamping. Further, the pressing mechanism may have a configuration in which the third pressing portion of the workpiece placed in the third region is pressed.

Further, for example, the third temperature is substantially equal to the second temperature, and the interval between the upper hot plate and the lower hot plate in the third region when the hot plate interval establishing mechanism presses the workpiece is set to be substantially equal to the second region. The interval between the intervals.

As described above, according to the embodiment of the present invention, it is possible to realize a continuous press apparatus which can produce a long-shaped product without causing defects in the workpiece during molding.

Embodiments of the invention are described below with reference to the drawings. The first figure shows an overall view of the stamping apparatus 1 of the present embodiment. The press apparatus 1 of the present embodiment is a device which thermally presses a plurality of workpieces of a prepreg film sheet in which a synthetic fiber sheet is impregnated with a resin to form a plate-shaped product having a predetermined thickness. In addition, the product is cut into a length of several meters after stamping. The shape of the component. As shown in the first figure, the apparatus body 2 of the press apparatus 1 is disposed in the vacuum chamber 10, and a series of press operations of the apparatus body 2 are performed in a vacuum state in the vacuum chamber 10.

As shown in the first figure, the apparatus body 2 is disposed substantially at the center of the vacuum chamber 10. On the right side of the apparatus body, a sheet arrangement area 16 in which a plurality of rollers R of a prepreg film sheet are disposed is disposed, and in the figure, A product arrangement area 17 in which press forming is disposed is disposed on the left side. The side of the vacuum chamber 10 is adjacent to the sheet arrangement area 16 and the product arrangement area 17, and an entrance door 18 and an exit door 19 are provided, respectively. Thus, the drum R of the semi-cured film sheet can be replenished from the entrance door 18, and the product can be taken out from the exit door 19. Further, a cutter 22 is disposed between the product placement region 17 and the apparatus main body 2, and the product continuously formed by the transmission device main body 2 is cut into an appropriate length.

Next, the configuration of the vacuum chamber 10 will be described. The vacuum chamber 10 is provided with a vacuum pump 15a for extracting air from the vacuum chamber 10, and a valve 15b for introducing air into the vacuum chamber 10. In the present embodiment, by controlling the operation of the vacuum pump 15a and opening and closing the valve 15b, the pressure inside the vacuum chamber 10 can be changed between vacuum and atmospheric pressure. That is, when the semi-cured film sheet is replenished and the product is taken out, the air pressure in the vacuum chamber 10 is taken as the atmospheric pressure, and the air pressure in the vacuum chamber 10 is taken as the vacuum in the hot stamping of the workpiece.

Further, as shown in the first figure, the apparatus body 2 is transmitted through the main leg portion 242, and the rigid body is supported by the base B. The vacuum chamber 10 is supported by the base B by the chamber support leg 11. Further, the bottom surface 12 of the vacuum chamber 10 is provided with a plurality of openings 12a, and each of the main leg portions 242 is disposed to penetrate the opening 12a. Further, the outer leg portion 242 of the apparatus main body 2 is covered by the bellows tube 14 from the outer edge of the opening portion 12a. The upper end 14a of the bellows 14 is open The mouth portion 12a and the lower end 14b of the bellows tube 14 are joined to the base B by full-circle welding to prevent air from entering the vacuum chamber 10 through the opening portion 12a.

In the present embodiment, as described above, the main leg portion 242 of the apparatus body 2 is not in contact with the vacuum chamber. Moreover, the inner wall portion of the vacuum chamber 10 and the device body are also not in contact with each other. Therefore, even if the vacuum chamber 10 is distorted by the difference in air pressure between the inside and the outside of the vacuum chamber 10, the apparatus body 2 that is not in contact with the vacuum chamber 10 is not distorted. Thereby, precise press working can be performed by the apparatus body 2 even under vacuum.

Next, the configuration of the apparatus body 2 will be described. The second figure is a side view of the device body 2. As shown in the second figure, the apparatus main body 2 has a transport mechanism 100 for transporting a workpiece by the side belt mechanism 120 and the lower belt mechanism 140 arranged in the vertical direction, and the transport mechanism 100 is disposed in the transport mechanism 100. The hot stamping mechanism 300 for hot stamping of the workpiece; and the cold stamping mechanism 400 for performing the hot stamping of the workpiece after the hot stamping is disposed in the transport mechanism 100. The conveyance mechanism 100, the hot press mechanism 300, and the cold press mechanism 400 are rigidly supported by the susceptor B through the frame unit 200. Specifically, the base B is fixed with the adjustment plate 241, and the main leg portion 242 of the frame portion 200 is attached to the adjustment plate 241 via the leveling bolt 243.

Next, the configuration of the transport mechanism 100 will be described. In the embodiment of the present invention, as shown in the first figure, the prepreg film sheet S is pulled out from the roll R of the prepreg film sheet disposed in the sheet arrangement area 16, and is conveyed to the product arrangement area 17. In the following description, the side of the sheet arrangement area 16 (the right side in the drawing) is defined as "upstream measurement", and the side (left side in the figure) of the product arrangement area 17 is defined as "downstream side" with respect to the apparatus main body 2. Moreover, the direction from the upstream side to the downstream side is defined as "transport direction". The direction from the downstream side toward the upstream side is defined as the "reverse direction".

The upper belt mechanism 120 of the transport mechanism 100 includes a pulley 121 on the downstream side, a pulley 122 on the upstream side, and a steel belt 123 that is slid over the endless belts of the two pulleys 121 and 122. The rotation shafts 121a and 122a of the pulleys 121 and 122 are rotatably attached to the upper frame portion 210 of the frame portion 200 through the respective bearings 121b and 122b. Here, the bearings 121b and 122b are biased in directions apart from each other, and a predetermined tension is imparted to the steel belt 123. Therefore, when the lower side portion 123a of the steel belt 123 is moved from the upstream side to the downstream side, the pulleys 121 and 122 are rotated in the figure by the frictional force acting between the steel belt 123 and the pulleys 121 and 122. Hour direction.

Next, a mechanism for imparting tension to the steel belt 123 will be described. The third figure is a side view of the vicinity of the pulleys 121 and 122 of the upper endless belt mechanism. As shown in the third figure, the bearing 122b is attached to the upstream side end of the upper frame portion 210 of the frame portion 200, and the bearing 121b is attached to the downstream side end.

The upstream side end portion (the right side in the drawing) of the upper frame portion 210 is formed with The guide frame 212 having a shape includes a pair of rail portions 212a and 212b extending in the transport direction and a connecting portion 212c connecting the rail portions 212a and 212b on the downstream side. The bearing 122b is held by the rail portions 212a and 212b of the guide frame 212, and can be moved only in the conveying direction and the retreating direction. Further, the connecting portion 212c is attached with a screw 122c extending in the conveying/retracting direction. The upstream end of the screw 122c is engaged with the bearing 122b, and the position of the bearing 122c can be adjusted to the conveying direction by turning the screw 122c. After the positioning, the screw 122c is fixed to the connecting portion 212c and the bearing 122b by a nut. Thereby, the bearing 122b is fixed.

Further, a guide frame 211 is formed at a downstream end portion of the upper frame 210, and the guide frame includes a pair of rail portions 211a and 211b extending in the transport direction. Bearing 121b on the downstream side of the upper side belt mechanism 120 It is held by the rail portions 211a and 211b of the guide frame 211, and can be moved only in the transport/retraction direction. Further, a cylinder 121c is attached to the upper frame 210. The downstream end of the cylinder 121c is engaged with the bearing 121b, and the bearing 121b is biased to the downstream side by the cylinder 121c. Thereby, the tension is given to the steel belt 123. Further, the bearing 121b on the downstream side is configured to be minutely movable in the transport/retraction direction. The lower portion 123a of the steel strip 123 is stretched downward by the hot stamping mechanism 300 and the cold stamping mechanism 400. As described above, in the embodiment of the present invention, since the bearing 121b and the pulley 121 are slightly moved in the backward direction following the operation of the steel belt 123, excessive tension is not applied to the steel belt 123. Therefore, in the present embodiment, even if the steel belt 123 is stretched to the hot stamping mechanism 300 and the cold stamping mechanism 400, it does not break.

Further, as shown in the second figure, the lower side belt mechanism 140 of the conveying mechanism 100 has a steel belt 143 that straddles the downstream side pulley 141, the upstream side pulley 142, and the two pulleys 141, 142. Endless belt. The rotation shafts 141a and 142a of the pulleys 141 and 142 are rotatably attached to the lower frame portion 230 of the frame portion 200 through the respective bearings 141b and 142b. Here, the bearings 141b and 142b are biased in directions apart from each other, and the steel belt 143 is given a predetermined tension. Therefore, when the upper portion 143a of the steel strip 143 is moved from the upstream side to the downstream side, the pulleys 141, 142 are rotated in the reverse direction by the frictional force acting between the steel belt 143 and the pulleys 141, 142. Hour direction.

The mechanism for biasing the bearings 141b and 142b supporting the pulleys 141 and 142 of the lower side belt mechanism 140 is the same as that of the upper belt mechanism 120. In other words, the upstream side bearing 142b is determined by the screw adjustment to determine the position of the conveyance direction, and is fixed to the lower frame portion 230 through the guide frame. Further, the bearing 141b on the downstream side can be slightly moved in the transport/retraction direction, The cylinder mechanism is biased in the conveying direction.

The portion 123a below the steel belt 123 of the upper belt mechanism 120, the portion 143a above the steel belt 143 of the lower belt mechanism 140, and the workpiece held by the two steel belts are formed by The gripper 150 is sent to the transport direction. Next, the configuration of the gripper 150 will be described.

As shown in the second figure, the gripper 150 has a pair of holding plates 151 and 152 and a pair of body members 155 (described later) that support the holding plates 151 and 152. The upper holding plate 151 is disposed between the upper portion 123b and the lower portion 123a of the steel belt 123 of the upper belt mechanism 120. Further, the lower holding plate 152 is disposed between the upper side portion 143a and the lower side portion 143b of the steel belt 143 of the lower side belt mechanism 140. When the holding plates 151 and 152 are driven to approach each other, the workpiece M disposed between the steel belts 123 and 143 and the steel belts 142 and 143 is sandwiched between the two holding plates 151 and 152.

Next, the configuration of the gripper 150 will be described. The fourth figure is a side view of the gripper 150 of the embodiment of the present invention. The fifth figure is a front view of the gripper 150 viewed from the backward direction (view of the direction of the I-I arrow in the second figure). Further, the sixth drawing is a plan view of the gripper 150, and the seventh drawing is a view of the gripping plate 152 on the lower side of the gripper 150 viewed from below (the view of the arrow in the direction of the arrow in the fifth arrow III-III). Further, the eighth diagram shows a side view in which the workpiece M is conveyed by the gripper 150.

As shown in the fourth and fifth figures, the holding plates 151 and 152 are plate-like members extending in the width direction of the steel belt 143, and the body 155 of the grip 150 is slidably movable in the vertical direction. Specifically, the side of the transport direction side (downstream side) of the body 155 is provided with a grip plate support rail 155b, and the grip plate support rail 155b and the engaging portions 151a, 152a provided on the respective grip plates 151, 152 ( Figure 6 and Figure 7) The moving direction of the holding plates 151, 152 is limited only to the vertical direction. The holding plates 151, 152 are driven to be close to each other by one of the cylinders 156a, 157a and the cylinder rods 156b, 157b respectively driven by oil pressure or air pressure to the first cylinder driving mechanism 156 and the two pairs of second cylinder driving mechanisms 157. /separate. The cylinder 156a of the first cylinder drive mechanism 156 is fixed to the body 155, and the front end of the cylinder rod 156b is fixed to the lower holding plate 152. Therefore, by driving the first cylinder driving mechanism 156, the lower holding plate 152 can be moved up and down with respect to the body 155. Further, the cylinder 157a of the second cylinder drive mechanism 157 is fixed to the lower surface of the lower holding plate 152, and the front end of the cylinder rod 157b is fixed to the upper holding plate 151. Therefore, by driving the second cylinder drive mechanism 157, the upper holding plate 151 can be approached/separated from the lower holding plate 152. Further, as shown in the fourth and fifth figures, the cylinder 156a of the first cylinder mechanism 156 is provided for each of the pair of bodies 155 (that is, at both ends in the width direction of the lower holding plate 152), and second. The cylinders 157a of the cylinder mechanism 157 are disposed one at each of the four corners of the lower holding plate 152.

Driving the first cylinder driving mechanism 156 to lift the lower holding plate 152 by a first distance while driving the second cylinder driving mechanism 157 so that the upper holding plate 151 is only close to the second distance of the lower holding plate by a first distance, When the side holding plate 152 is raised while the upper side holding plate 151 is lowered, the two plates 151, 152 are close to each other. On the other hand, the driving first cylinder driving mechanism 156 lowers the lower holding plate 152 by only a first distance while driving the second cylinder driving mechanism 157 to move the upper holding plate 151 away from the lower holding plate by a second distance. At the same time, the lower holding plate 152 is lowered while the upper holding plate 151 is raised, and the two plates 151, 152 are apart from each other.

As shown in the second, fourth, and fifth figures, the guide rail 231 is provided in the lower frame portion 230 in the transport/retraction direction. One of the grippers 150 The bottom surface of the body 155 is provided with a leg portion 155a that is engaged with the guide rail 231. By the snapping, the gripper 150 can be moved from the upstream side to the downstream side along the guide rail 231 or from the downstream side to the upstream side. Further, as shown in the fifth figure, the guide rails 231 are arranged side by side in the width direction.

Next, referring to the eighth (a) to eighth (d) drawings, the transfer order of the workpiece M of the gripper 150 will be described. First, the gripper 150 is in an initial state (the eighth (a)) from the backward side, and drives the first cylinder drive mechanism 156 and the second cylinder drive mechanism 157 to bring the grip plates 151 and 152 closer to each other. Thus, as shown in the eighth (b), the holding plates 151 and 152 of the gripper 150 are in a state of holding the steel belts 123 and 143 and the workpiece M.

From this state, when the gripper 150 is moved in the transport direction, the steel belts 123 and 143 and the pulleys 121, 122, 141, and 142 are rotated in accordance with the movement of the gripper 150, as shown in the eighth (c), The workpiece held in the steel belt is transported in the transport direction.

The gripper 150 is moved to the front of the hot stamping mechanism 300 (the position shown by a dashed line in the fourth drawing), and is driven to move the gripping plates 151, 152 away from each other to open the steel strips 123, 143 and the workpiece. M (eighth (d) diagram). Next, the gripper 150 is moved to the reverse direction. At this time, since the grip plates 151 and 152 do not hold the steel belts 123 and 143, the steel belts 123 and 143 and the workpiece M therebetween do not move even if the gripper 150 retreats. As a result, it returns to the initial state of the eighth (a) figure. Then, the steel belts 123 and 143 and the workpiece M are again sandwiched between the grip plates 151 and 152 to move in the conveyance direction. As described above, by moving the gripper plates 151 and 152 on and off, the gripper 150 is reciprocated, and the steel strip can be intermittently moved in the transport direction to transport the workpiece.

The advance/retraction of the gripper 150 is performed by a cylinder mechanism. As shown in the second figure, the cylinder 153 constituting the cylinder mechanism is fixed to the lower frame portion. 230. Further, the piston 154 inserted into the cylinder 153 at one end is attached to the body 155 of the gripper 150 via the coupling mechanism 154a. Then, the piston 154 is moved forward and backward by driving the cylinder 153, and the gripper 150 is advanced/retracted. Further, as shown in the fifth and sixth figures, the cylinder 153 is provided with two pistons 154 and 154a, respectively.

Next, the configuration of the hot stamping mechanism 300 will be described. The ninth drawing is a side cross-sectional view of the hot stamping mechanism 300. Further, the tenth drawing is a front view of the hot stamping mechanism viewed from the downstream side (the view of the arrow II-II in the second drawing). As shown in FIG. 9, the hot stamping mechanism 300 is a device that is configured to be hot-stamped between the hot plate 322 that is movable in the up-and-down direction and the lower hot plate 324 that is fixed to the lower frame portion 230. . The upper hot plate support frame 312 is fixedly supported by the upper frame portion 210 on both sides in the transport direction. The upper hot plate 322 is suspended from the lower portion of the upper hot plate support frame 312 through the hot plate moving cylinder mechanism 370 and the movable platform 336. Further, the lower hot plate 324 is fixed to the stage 314 which is fixedly supported by the lower frame portion 230 via the stay 244.

In the embodiment of the present invention, as shown in the ninth and tenth views, the upper hot plate 322 is suspended from the upper hot plate support frame 312 by three pairs (six) of hot plate moving cylinder mechanisms 370. As shown in the tenth diagram, the cylinder mechanism 370 has a cylinder 371, a rod 372 extending from the cylinder 371, and a connecting mechanism 373 provided at the front end of the rod 372. The cylinder 371 is fixed to the side of the upper hot plate support frame 312. Further, the rod 372 and the movable platform 336 are connected by a connecting mechanism 373. Therefore, the movable platform 336 can be moved up and down by the drive lever 372. Further, the hot plate moving cylinder mechanism 370 advances and retracts the rod 372 by an air pressure or a hydraulic mechanism.

Moreover, in the embodiment of the present invention, six punch cylinder mechanisms 340 are provided. The upper hot plate supports frame 312. The upper hot plate 322 is lowered by the hot plate moving cylinder mechanism 370 to bring the workpiece to the hot plate, and then the upper hot plate 322 is pressed downward to perform pressing. Each of the press cylinder mechanisms 340 has a piston 342, a sleeve 344 in which the piston 342 is inserted, and a fixing plate 346 for fixing the sleeve 344 to the lower surface of the upper hot plate support frame 312. The fixing plate 346 is integrated with the sleeve 344 by means of, for example, welding, and the fixing plate 346 is fixed to the upper hot plate supporting frame 312 by the bolt 348 (Fig. 10), and the sleeve 344 is attached to the upper heat. The disk supports frame 312. Further, the movable platform 336 is fixed to the lower end of the piston 342. Therefore, by controlling the hydraulic pressure in the sleeve 344 by a hydraulic pump (not shown), the workpiece can be pressed with a desired load.

Further, as shown in the ninth and tenth views, from the lower surface of the movable platform 336, a plurality of rods 352 extending from the vertically upper portion are provided on the both sides in the width direction of the upper hot plate. Similarly, from the top of the platform 314, a plurality of rods 354 extending from the vertically upward and downward portions are provided on both sides in the width direction of the lower hot plate. Each of the upper distance rods 352 is disposed opposite to each of the lower distance rods 354. When the upper hot plate 322 is driven to approach the lower hot plate 324 by the punch cylinder mechanism 340, the upper portion of the upper distance rod 352 is attached to the lower portion of the lower rod 354. The upper hot plate 322 will not fall further. That is, by the distance bars 352, 354, the interval between the upper hot plate 322 and the lower hot plate 324 during hot stamping, that is, the thickness of the workpiece can be controlled.

A heater (not shown) is provided in the upper hot plate 322 and the lower hot plate 324 to heat the respective hot plates to a desired temperature. Further, a heat insulating material 334 is provided between the movable platform 336 and the upper hot plate 322 so that the heat of the upper hot plate 322 does not escape to the piston side. Similarly, a heat-dissipating material 338 is disposed between the platform 314 and the lower hot plate 324 to enable the lower hot plate 324. The heat will not escape the platform 314 side.

As shown in the ninth embodiment, in the embodiment of the present invention, the hot stamping mechanism 300 is fixed with a preheating zone 300a on the upstream side, a first heating zone 300b located at a substantially central portion of the conveying/retracting direction, and a downstream side. The second heating zone 300c. The dimensions of the transport directions of the zones are substantially the same, and each zone is provided with two stamping cylinder mechanisms 340. Further, the size of the conveyance direction of each zone and the amount of the workpiece to be processed by one of the grippers 150 (second diagram) are substantially equal. Therefore, in the present embodiment, the workpiece is sequentially pressed in the preheating zone 300a, the first heating zone 300b, and the second heating zone 300c.

Further, the temperatures of the upper and lower hot plates 322, 324 and the lengths of the rods 352, 354 (i.e., the hot plate spacing) are set to different values for each of the zones 300a, 300b, and 300c. That is, the thickness of the workpiece is adjusted according to the structure, characteristics, size, and the like of the workpiece, and the lengths of the distance rods 352 and 354 corresponding thereto can be individually controlled according to each zone.

Further, the press cylinder mechanism 340 is formed to be individually driven in each of the zones 300a, 300b, and 300c. In the present embodiment, the load applied to the workpiece in each zone is determined by the length of the rods 352, 354, the size and characteristics of the workpiece. That is, after the distance between the rods 352 and 354, the oil pressure in the sleeve 344 is increased to increase the load applied to the movable platform 336, and the load-increasing portion is not transmitted through the workpiece M, and is transmitted through the distance rod. 352, 354 are accepted by the platform 314, and the hot plates 322, 324 do not affect the load applied to the workpiece M. In other words, each of the press cylinder mechanisms 340 can supply the load of the workpiece M sufficiently to the movable platform 336, and even if more load is applied, it is only a power loss. Further, in the present embodiment, since the degree of reaction of the workpiece and the length of the distance rods 352 and 354 can be set to different values depending on the respective areas, The amount of load applied to the workpiece varies depending on the area. Therefore, by individually controlling the load applied to the piston 342 of the press cylinder mechanism 340 by each zone, the upper hot plate 322 can be driven only by the load required to press the workpiece M disposed in each of the zones 300a, 300b, 300c. And can reduce the loss of power to the necessary minimum.

The workpiece to be hot stamped by the hot stamping mechanism 300 is then sent to the cold stamping mechanism 400 by the gripper 150. As shown in the second figure, the cold press mechanism 400 has a lower cooling plate 422 suspended from the upper frame portion 210 through the press cylinder mechanism 440, and a lower cooling plate 424 fixed to the upper frame portion 230 via the support rod 248. Both the upper cooling plate 422 and the lower cooling plate 424 are internally provided with piping for circulating cold coal (water, air, oil, etc.). The temperature of the cooling plates 422, 424 is kept lower than the hot plates 322, 324 by circulating cold coal in the tubes. Further, the ram cylinder mechanism 440 can be driven to separate/close the upper cooling plate 422 with respect to the lower cooling plate 424.

In the present embodiment, the upper cooling plate 422 is lowered by driving the press cylinder mechanism 440, so that the workpiece can be in close contact with the upper cooling plate 422 and the lower cooling plate 424. At this time, since the temperature of the workpiece is higher than the two cooling trays 422 and 424, heat is generated from the workpiece to the cooling trays 422 and 424, and the temperature of the workpiece is lowered. Therefore, the workpiece to be hot-stamped by the hot stamping mechanism 300 can be cooled by the cold stamping mechanism 400. In addition, the transport direction dimension of the upper cooling disk 422 and the lower cooling disk 424 is slightly larger than the one-time delivery amount of the gripper 150. Therefore, the hot-stamped finished workpiece discharged from the hot stamping mechanism 300 is exhausted. The cooling is performed by the cold stamping mechanism 400.

Further, as shown in the ninth diagram, a nip roller mechanism for supporting the steel belts 123, 143 is provided at both ends of the conveying direction of the hot stamping mechanism 300. 361, 362, 363, 364. The nip roll mechanism 361 supports the steel belt 123 on the downstream side of the hot stamping mechanism 300, and the 362 series supports the steel belt 123 on the upstream side, and supports the steel belt 143 on the downstream side, and the 364 system is supported on the upstream side. With 143.

Next, the configuration of each of the pressure feed roller mechanisms 361 to 364 will be described. As shown in FIG. 9, the nip roller mechanisms 361 to 364 have nip rollers 361a to 364a and bearing portions 361b to 364b that support the nip roller at both ends. Here, the biasing mechanism of the nip roller mechanism will be described. The eleventh figure shows a side view of the nip rolls mechanisms 361 and 363 on the downstream side. As shown in the figure, each of the nip rollers 361a and 363a is elastically biased to the side of the steel belt by the cylinder mechanisms 361c and 363c. That is, the nip roll 361a of the steel belt 123 supporting the upper side belt mechanism 120 is biased downward. On the other hand, the nip roller 363a of the steel belt 143 supporting the lower side belt mechanism 140 is biased upward. Further, the nip rollers mechanisms 362 and 364 on the upstream side are also provided with cylinder mechanisms substantially the same as those of the nip rollers mechanisms 361 and 363.

The upper hot plate 322 is separated from the lower hot plate 324. That is, when hot stamping is not performed, the nip rolls mechanisms 361 to 364 are spring-stretched steel belts 123, 143 so that the steel belts 123, 143 are only slightly separated from the upper and lower hot plates 322, 324. Further, when the upper hot plate 322 is lowered from this state, the steel belt 123 of the upper belt mechanism 120 comes into contact with the upper hot plate 322, and then the steel belt 123 is integrally formed with the upper hot plate 322 and moved downward. At this time, the cylinder mechanisms of the nip roller mechanisms 361 and 362 are controlled such that the nip rollers 361a and 362a are also moved downward in a state of abutting against the steel belt 123. Then, the steel belt 123 of the upper belt mechanism 120 passes through the workpiece and the steel belt 143 of the lower belt mechanism 140, and when the upper hot plate 322 is lowered, the lower belt is moved along with the upper hot plate 322. The steel belt 143 of the mechanism 140 is also lowered to abut the lower hot plate 324. At this time, the nip rollers 363a and 364a also move downward in a state of abutting against the steel belt 143. The workpiece is pressed between the hot plates by the above-described process. As described above, in the present embodiment, the steel belts 123, 143 are elastically pressed against the nip roller mechanisms 361 to 364 so as not to be strongly spliced to the corners of the hot plates 322 and 324.

Further, after the end of the pressing, the upper hot plate 322 is raised, and the lower hot plate 324 is rapidly separated. At this time, the cylinder mechanisms of the nip roller mechanisms 361 to 364 are controlled such that the upper steel belts 123 and 143 abut against the workpiece M for a short period of time (for example, between 1 second), and then the steel belt 123, 143 slowly moves toward the upper and lower hot plates 322, 324. Therefore, the workpiece is not damaged by the rapid movement of the steel belt up and down.

Further, when the gripper 150 (fourth drawing) grips the workpiece, the upstream side nip rollers 362a and 364a move toward each other with the movement of the steel belts 123 and 143, and the steel strips 123 and 143 are biased. The portion 123a below the steel strip 123 and the portion 143a above the steel strip 143 are formed substantially horizontally. Therefore, the edges of the holding plates 151, 152 by the grip claws do not damage the steel belt.

In the present embodiment, as shown in the second figure, the portion 123b above the steel strip 123 and the portion 143b below the steel strip 143 are provided with removers 125 and 145. The removers 125 and 145 are provided with, for example, a doctor blade, and the resin sheets adhering to the outer peripheral surfaces of the steel belts 123 and 143 are removed by press processing.

Next, the punching procedure of the workpiece of the press apparatus 1 of the embodiment of the present invention described above will be described. Further, in the following description, a prepreg film sheet containing a thermosetting resin is formed into a workpiece M. Further, a portion from the end of the downstream end of the workpiece M from the portion of the gripping portion of the gripper 150 is defined as the first portion, and the length of the portion of the feed portion adjacent to the upstream portion of the first portion. Part of the definition is the second part, A portion of the second portion that is adjacent to the length of the delivery portion of the upstream side is defined as a third portion, and a portion that is opposite to the length of the portion of the third portion that is adjacent to the upstream side is defined as a fourth portion. Part.

First, the first portion is sent to the preheating zone 300a of the hot stamping mechanism 300 (the ninth drawing) by the gripper 150 (fourth drawing). Next, the hot plate moving cylinder mechanism 370 (the tenth figure) is driven to wind the first portion of the workpiece M between the hot plates 322 and 324. Further, the driving press cylinder mechanism 340 presses the first portion of the workpiece M. Here, the temperature of the hot plates 322, 324 in the preheating zone 300a is lower than the hardening temperature of the resin component of the workpiece, and is controlled to be close to the temperature at which the glass is transferred. Therefore, the resin portion of the first portion is softened, and since the temperature is low, the thermal hardening of the workpiece is hardly performed, and the first portion is adjusted to a desired thickness.

Next, by reducing the hydraulic pressure of the press cylinder mechanism 340 and the hot plate moving cylinder mechanism 370, the hot plates 322, 324 are separated from each other to open the workpiece M. Further, the workpiece M is sent to the transport direction by the gripper 150. As a result, the first portion of the workpiece M is moved to the first heating zone 300b, and in addition, the second portion is moved to the preheating zone 300a. Next, the hot plate moving cylinder mechanism 370 is driven to bring the hot plates 322, 324 into proximity with each other, and the press cylinder mechanism 340 is driven to apply a load to the upper hot plate 322. Thereby, the first portion of the workpiece M is stamped in the first heating zone 300b, and the second portion is stamped in the preheating zone 300a. Here, since the temperature of the hot plates 322, 324 in the first heating zone 300b is higher than the temperature of the hot plate in the preheating zone 300a, a certain degree of thermosetting reaction is performed in the first portion of the workpiece M. Further, the shape of the second portion is adjusted in the preheating zone 300a. In addition, since the workpiece M is somewhat shrunk by the heat hardening reaction, the distance rod 352 is established. The interval of 354 (the tenth figure) is such that the interval between the hot plates when the workpiece is punched in the first heating zone 300b is somewhat narrower than the interval of the hot plate when the workpiece is punched in the preheating zone 300a.

Next, by reducing the hydraulic pressure of the press cylinder mechanism 340 and the hot plate moving cylinder mechanism 370, the hot plates 322, 324 are separated from each other to open the workpiece M. Further, the workpiece M is sent to the transport direction by the gripper 150. As a result, the first portion of the workpiece M moves to the second heating zone 300c, the second portion moves to the first heating zone 300b, and the third portion moves to the preheating zone 300a. Next, the hot plate moving cylinder mechanism 370 is driven to bring the hot plates 322, 324 into proximity with each other, and the press cylinder mechanism 340 is driven to apply a load to the upper hot plate 322. Thereby, the first portion of the workpiece M is stamped in the second heating zone 300c, the second portion is stamped in the first heating zone 300b, and the third portion is stamped in the preheating zone 300a. Here, the temperature of the hot plates 322, 324 in the second heating zone 300c is about the same as the first heating zone 300b. The workpiece M is sequentially heated in the first and second heating zones 300b and 300c, and finally subjected to a thermosetting reaction. Thus, the first portion of the workpiece M is shaped into a desired cross-sectional shape. Further, in the first heating zone, a certain portion of the second portion of the thermosetting reaction is carried out. Further, the shape of the third portion is adjusted in the preheating zone 300a. Further, since the heat hardening reaction of the workpiece M proceeds in the second heating zone and the workpiece is shrunk, the distance between the rods 352, 354 is set so that the workpiece is punched in the second heating zone 300c. The interval between the hot plates at the time is somewhat narrower than the interval between the hot plates when the workpiece is punched in the first heating zone 300b.

Next, by reducing the hydraulic pressure of the press cylinder mechanism 340 and the hot plate moving cylinder mechanism 370, the hot plates 322, 324 are separated from each other to open the workpiece M. Furthermore, the workpiece M is carried by the gripper 150. Send directions. As a result, the first portion of the workpiece M is discharged from the hot stamping mechanism 300 and transferred to the cooling trays 422, 424 of the cold stamping mechanism 400. Further, the second portion is moved to the second heating zone 300c, the third portion is moved to the first heating zone 300b, and the fourth portion is moved to the preheating zone 300a. Next, the hot plate moving cylinder mechanism 370 and the press cylinder mechanism 440 (second drawing) are driven to bring the hot plates 322 and 324 and the cooling plates 422 and 424 close to each other, and the press cylinder mechanism 340 is driven to apply a load to the upper hot plate 322. Thereby, the first portion of the workpiece M abuts against the cooling plates 422, 424 and the first portion is cooled. Further, the second portion is stamped in the second heating zone 300c, the third portion is stamped in the first heating zone 300b, and the fourth portion is stamped in the preheating zone 300a.

As described above, in the press apparatus 1 of the present embodiment, the conveyance of the workpiece and the press system are alternately performed, and the transport direction size is larger than that of the hot plate and the cooling plate, and the elongated workpiece M can be formed. Further, the workpiece M is firstly shaped in the preheating zone 300a, then formed in the first heating zone 300b and the second heating zone 300c by a heat hardening reaction, and then cooled by the cold stamping mechanism 400. As described above, since the shape of the hot stamping is performed after the shape is preheated, the heat hardening reaction is performed without adjusting the shape, and the workpiece M does not cause defects (the disorder of the fiber of the semi-cured film or the resin). Flow, whitening of the workpiece, uneven thickness, etc.). Further, in the present embodiment, both the preheating and the hot stamping are performed on a pair of large hot plates 322 and 324 having no connection wires. Therefore, when the workpiece having a larger conveying direction dimension than the hot plate is formed, defects such as the connecting wire are not generated.

Further, in the present embodiment, the heating of the workpiece M is performed at two places of the first heating zone 300b and the second heating zone 300c. That is, the time for hot stamping is twice the warm-up time. Even in the preheating zone 300a where the press is performed at a low temperature, the thermal hardening of the workpiece M is slightly performed. this In the embodiment, since the hot stamping time can be lengthened longer than the preheating time, the shape of the workpiece M can be adjusted in the preheating zone 300a with almost no thermal hardening, and the reheating zone can be thermally hardened. Further, in the present embodiment, two heating zones are prepared for one preheating zone, but the present invention is not limited to the above configuration, and the number of each zone can be appropriately changed in accordance with the resin material for forming the workpiece.

Further, in the present embodiment, the material containing the thermosetting resin is hot-stamped, but the present invention is not limited to the above configuration, and may be used for a workpiece containing a thermoplastic resin. That is, when the workpiece including the thermoplastic resin is hot-stamped, the shape of the workpiece is first adjusted at a low temperature in the preheating zone. At this time, since the workpiece is not heated, the viscosity is high and the flow of the resin is prevented. Next, the workpiece is formed at a high temperature in the first and second heating zones, and the shape is fixed on the cooling disk.

Further, in the present embodiment, the gripper 150 is disposed on the reverse direction side with respect to the hot stamping mechanism 300. However, the present invention is not limited to this configuration, and the gripper 150 is disposed on the transport direction side with respect to the hot stamping mechanism 300, that is, may be disposed between the hot stamping mechanism 300 and the cold stamping mechanism 400, and a relatively cold stamping mechanism. It is placed on the transport direction side.

Further, in the present embodiment, the workpiece M is conveyed by the steel belts 123 and 143 which are made of steel, but the present invention is not limited to the above configuration. In other words, instead of the steel belts 123 and 143, an endless belt formed of a heat-resistant resin such as an endless belt of another metal or a polyimide may be used.

Further, in the present embodiment, heaters are provided in the upper hot plate 322 and the lower hot plate 324, whereby the two hot plates are heated. However, the present invention is not limited to the above configuration, and may be, for example, a configuration in which heating is performed by a hot disk circulating heat medium.
