Description

Processing method of film sealing layer

Technical Field

The invention relates to the field of marine engineering equipment, in particular to a liquefied gas storage cabin of marine equipment such as ships and the like, in particular to a processing method of a thin film sealing layer of the liquefied gas storage cabin of transportation equipment, in particular to the marine equipment such as ships and the like. The storage tanks are in particular liquefied gas storage tanks for marine equipment such as ships, wherein the liquefied gas is for example liquefied natural gas, liquid nitrogen, liquid oxygen, liquid hydrogen, liquid helium or the like.

Background

Each component of the lng storage tank needs to meet a severe demand to meet the demand for stable storage and no leakage of lng. In the related art, for a ship for storage, it is necessary to separate cabins with special steel to ensure that they do not leak from each other and can withstand a low temperature of-160 ℃ to ensure insulation of the interior of the hull.

Most of the related transport vessels have outer wall thickness of 3 feet, and the inner wall is specially designed and built by nickel alloy steel, so that the low-temperature state of liquefied natural gas can be ensured. Once the inner wall has fissures, all lng will fill the space between the inner and outer walls. Wherein the performance of the layer of the inner wall in direct contact with the lng is critical for the transport effect. The performance of this layer, which is in direct contact with lng, is still to be improved.

A related method of processing is to move the forming modules at a uniform speed while the blank plate is placed in a predetermined position, thereby forming a predetermined shape on the blank plate. However, since the bulge area of the film sealing layer having superior performance is unique in shape, the bulge area thus formed at a uniform speed may have uneven thickness throughout, resulting in poor performance.

Thus, there is a need to provide a processing method to at least partially solve the above-mentioned problems.

Disclosure of Invention

The invention aims to provide a processing method. The method of the invention can press the pressing plate in the first stage of the downward movement of the driving mechanism after the blank plate is placed at the preset position, and only the shaping block is driven and the sliding part is kept static in the stage; the second stage of the downward movement of the drive mechanism drives both the shaping block and the slide member, the shaping block drive and the slide member drive being fixed relative to each other, preferably the speed of the shaping block being driven can also be different from the speed of the slide member being driven, more preferably even the shaping block speed and the slide member speed may not be in a fixed ratio (e.g. by a drive rod with involute surfaces or programmed control logic), the shaping block and slide member having different speeds cooperating to form a predetermined shape on the blank sheet. The bulge area of the film sealing layer formed by the process has uniform thickness and excellent performance.

It should be noted that, in order to facilitate the driving mechanism being able to perform driving in different directions (e.g. driving the shaping block in the vertical direction and driving the sliding member in the horizontal direction), it is often preferred to actuate the shaping block driving part and the sliding member driving part separately, and such an arrangement may result in that the shaping block driving part and the sliding member driving part cannot be accurately associated, so that the performance of the film sealing layer formed by the driven shaping block and the sliding member in cooperation is poor. In the invention, the shaping block driving part and the sliding part driving part are fixed relative to each other, so that the shaping block driving part and the sliding part driving part are accurately related, and the performance of the formed film sealing layer can be improved. On the other hand, the waviness of the film sealing layer, especially the bulge area, may be complicated in shape, and if the shaping block driving part and the sliding part driving part are cooperatively shaped at the same speed, the obtained film sealing layer may have uneven thickness and poor performance, and then preferably, the invention integrally drives the shaping block and the sliding part, and simultaneously ensures that the speeds of the driving block and the sliding part are unequal, even the speeds of the driving block and the sliding part are not in a linear relation, so that the thickness of the finally shaped film sealing layer is uniform and the performance is superior.

According to an aspect of the present invention, there is provided a method of processing a film sealing layer, the method comprising a step of forming a transverse penetrating wave on a blank sheet and a step of forming a longitudinal penetrating wave and a bulge region after the transverse penetrating wave is formed, wherein the step of forming the longitudinal penetrating wave is performed by a processing apparatus including a pair of sliding members, a pair of swage members, a shaping block, and a driving mechanism, wherein:

and operating a driving mechanism to bring the pair of sliding members closer to each other at a first predetermined speed while moving the shaping block downward at a second predetermined speed, the first predetermined speed and the second predetermined speed being specifically related with respect to a predetermined shape of the bulge region.

In one embodiment, the step of operating the drive mechanism comprises: the pair of slide members are brought closer to each other at a first predetermined speed that is non-uniform while the shaping block is moved downward at a second predetermined speed that is not equal to the first predetermined speed.

In one embodiment, the driving mechanism includes a main horizontal plate and a vertical plate connected as one body, and the sliding part driving part is a driving rod, wherein the step of operating the driving mechanism includes: the vertical plate is moved downward so that the driving rod contacts the force receiving portion of the sliding member.

In one embodiment, the step of lifting the swage block and the step of operating the drive mechanism include controlling a pilot link stop such that the tip of the pilot link stop abuts against the underside of the main horizontal plate when the pressure source nitrogen spring is at maximum compression.

in a second stage of the downward movement of the driving mechanism, the shaping block is moved downward at the second predetermined speed, and the pair of sliding members are brought close to each other at the first predetermined speed. In one embodiment, the step of operating the drive mechanism comprises: in a second stage of the downward movement of the drive mechanism, the vertical plate is moved downward such that different areas of the involute surface of the drive rod contact the force-receiving portion of the slide member.

Detailed Description

The present invention provides a method for processing a thin film sealing layer for a liquefied gas storage tank of a transportation apparatus, particularly marine equipment such as a ship, for example, a storage tank for storing LNG. The storage tank may be a marine equipped liquefied gas storage tank or a land cryogenic liquid plant. Fig. 1 to 6 show schematic views of a processing apparatus to which a manufacturing method according to a preferred embodiment of the present invention is applied.

It is to be understood that the directional and positional terms referred to herein are merely exemplary and not limiting. The description of the position of a component should be understood as a relative position and not an absolute position, and the description of the direction of extension of a component should be understood as a relative direction and not an absolute direction. Wherein directional terms, positional terms, relating to the processing apparatus may be understood with reference to the positions, orientations, etc. of the respective components illustrated in fig. 1-6. For example, terms such as "top side", "upward", "bottom side", "downward", etc. of the respective components of the processing apparatus may be explained with reference to the placement orientations of the processing apparatus shown in fig. 1, 5, 6, the "upward" and "downward" directions being in the vertical direction as shown by D3; the "lateral direction" and the "longitudinal direction" are two horizontal directions perpendicular to each other, wherein the lateral direction is shown by D2 and the longitudinal direction is shown by D1. The vertical direction D3, the lateral direction D2, and the longitudinal direction D1 are orthogonal in space. "longitudinal through waves" of the film seal layer refer to waves extending longitudinally and through the corrugated plate body, and "transverse through waves" refer to waves extending transversely and through the corrugated plate body.

Referring first to fig. 1, the processing apparatus 500 includes a pair of slide members 50 arranged side by side in the lateral direction, a pair of swage members arranged side by side in the lateral direction, a shaping block 80, and a drive mechanism 70. Wherein the pair of sliding members 50 can be laterally moved away from and toward each other, and the pair of pressing members are correspondingly positioned on the top sides of the pair of sliding members 50, so that the film sealing layer can be pressed between the pair of sliding members 50 and the pair of pressing members. The shaping block 80 is located between the pair of sliding members 50, and the shaping block 80 further includes a longitudinal wave shaping block 81 and a bulge region shaping block 82 as shown in fig. 2. The driving mechanism 70 includes a slide member driving portion that contacts the pair of slide members 50, and a molding block driving portion that is connected to the molding block 80.

The driving mechanism 70 may include a main horizontal plate 71 and a vertical plate 72 integrally connected, the vertical plate 72 extending downward from a center in a lateral direction of the main horizontal plate 71, a sliding member driving part such as a driving rod 77, a top of the driving rod 77 being fixed to the main horizontal plate 71; a shaping block 80 is fixed to the bottom end of the vertical plate 72. The pair of sliding members 50 each have a force-receiving pin 51 extending in the longitudinal direction, the force-receiving pin 51 having a smooth outer contour, and the driving lever 77 having an involute surface formed thereon for contacting the force-receiving pin 51. When the driving mechanism 70 drives the molding block 80 to move downward at a uniform speed, different areas of the involute surface of the driving rod 77 contact the sliding member 50, thereby causing the sliding member 50 to move as a whole at a variable speed.

It will be appreciated that in the embodiment shown in fig. 1, the drive mechanism 70 is a unitary member such that the molding block drive and the slide member drive are fixed relative to each other, the molding block drive and the molding block 80 are fixedly connected, and the slide member drive drives the slide member 50 in frictional contact, the arrangement being such that the speeds and directions of movement of the molding block drive and the slide member drive are uniform, but the speeds and directions of movement of the molding block 80 and the slide member 50 are different. Wherein the speeds of the pair of sliding members 50 approaching each other in the lateral direction under the action of the driving mechanism 70 are referred to as first predetermined speeds, and the speed of the downward movement of the driving mechanism 70 is referred to as second predetermined speeds.

Preferably, the platen 60 of the tooling device 500 for pressing over the blank panel may also be driven by the drive mechanism 70 in some cases so that the platen 60 can be lifted to allow an operator to place the blank panel between the platen 60 and the slide member 50. For example, in some embodiments, a coupling mechanism is provided between the drive mechanism 70 and the pair of platens 60, the coupling mechanism being configured to allow both the pair of platens 60 to move vertically with the drive; and also allows the driving mechanism 70 to move vertically with respect to the pair of pressing plates 60 when the pair of pressing plates 60 abut against the top sides of the pair of sliding members 50.

The drive mechanism 70 may include a pressure source nitrogen spring 74 disposed between the main horizontal plate 71 and the pair of platens 60, the pressure source nitrogen spring 74 being configured to be lockable to allow the pair of platens 60 to move vertically with the main horizontal plate 71 when it is at a maximum tensile length. In order to ensure that no relative displacement in the horizontal direction occurs between the main horizontal plate 71 and the pressing plate 60 when the main horizontal plate 71 moves relative to the pressing plate 60, the machining device 500 is further provided with an intermediate horizontal plate 73 and a guide connection limit lever 75. The middle horizontal plate 73 is fixedly connected below the main horizontal plate 71 through a connecting section 78, the top end of the pressure source nitrogen spring 74 is fixed on the middle horizontal plate 73, and the bottom ends of the pressure source nitrogen springs 74 are fixed on the pair of pressing plates 60. The bottom end of the guide connection limiting rod 75 is fixed on the pressing plate 60, the guide connection limiting rod 75 movably penetrates through the middle horizontal plate 73 and is provided with a limiting portion 751 which can abut against the top side of the middle horizontal plate 73 at the top end of the guide connection limiting rod 75, and the limiting portion 751 prevents the middle horizontal plate 73 from further moving upwards relative to the guide connection limiting rod 75. Preferably, the stop 751 of the pilot link stop lever 75 abuts the underside of the main horizontal plate 71 when the pressure source nitrogen spring 74 is at a minimum extension length (i.e., maximum compression). The pressure source nitrogen spring 74 is flip-chip mounted, and in the mounted state, the pressure source nitrogen spring 74 is directed downward at its top and upward at its bottom.

When it is desired to lift the platen 60, the drive mechanism 70 may be actuated to move it upwardly. In the first stage of the upward movement of the drive mechanism 70, the main horizontal plate 71, the intermediate horizontal plate 73 are moved upward relative to the platen 60, the pressure source nitrogen spring 74 is stretched between the intermediate horizontal plate 73 and the platen 60, and the guide connection stopper 75 penetrates the intermediate horizontal plate 73 so that the intermediate horizontal plate 73 moves upward relative to the guide connection stopper 75. When the pressure source nitrogen spring 74 is stretched to the maximum length while the stopper 751 of the guide connection stopper 75 is abutted against the top side of the middle horizontal plate 73, the upward movement process of the driving mechanism 70 enters the second stage. In the second stage of upward movement of the drive mechanism 70, the platen 60 moves upward with the drive mechanism 70, the platen 60 moving upward away from the slide member 50, allowing the operator to place a blank sheet between the platen 60 and the slide member 50.

After the blank sheet has been placed between the platen 60 and the slide 50, the drive mechanism 70 may be actuated to move it downwardly. In the first stage of the downward movement of the drive mechanism 70, the pressure source nitrogen spring 74 is at its longest extension length, and the stopper 751 of the guide connection stopper 75 abuts against the top surface of the intermediate horizontal plate 73, and the platen 60 is actuated by the drive mechanism 70 to move downward together with the drive mechanism 70. When the pressure plate 60 abuts against the top surface of the slide member 50, the downward movement of the drive mechanism 70 enters a second stage in which the pressure plate 60 is no longer moved, the drive mechanism 70 moves downward relative to the pressure plate 60, the pressure source nitrogen spring 74 is compressed, and the guide connection stopper 75 penetrates and slides relative to the intermediate horizontal plate 73. The second phase ends when the pressure source nitrogen spring 74 is at a minimum length while the stop 751 of the pilot link stop lever 75 abuts against the bottom surface 821 of the main horizontal plate 71.

In the second stage of the downward movement of the drive mechanism 70, the shaping block 80 and the slide member 50 are moved by the drive mechanism 70 and shape the blank sheet. That is, the first stage of the downward movement of the driving mechanism 70 functions to drive the platen 60; the second stage of the downward movement of the drive mechanism 70 serves to drive the shaping block 80 and the slide member 50.

The bottom surface 821 of the pressing plate 60 is provided with a projection 76 corresponding to the transverse wave on the blank plate, and the corresponding position of the slide member 50 is provided with the receiving area 52. When the machining device 500 machines the longitudinal penetration wave in the blank plate, the transverse penetration wave of the blank plate can be fixed by the protruding portion 76 and the receiving area 52, and deformation of the transverse penetration wave is avoided.

In other embodiments not shown, the platen 60 and the drive mechanism 70 may have other connection configurations, for example may be in a disconnectable connection configuration such that the drive mechanism and the platen are not engaged during a first stage of upward movement of the main horizontal plate, but are engaged upon entering a second stage of upward movement; the first stage drive mechanism of the downward movement of the main horizontal plate engages the pressure plate and the drive mechanism and pressure plate are disconnected upon entry into the second stage of the downward movement. Alternatively, the platen may have a separate drive mechanism that can be actuated independently of the drive block, the drive mechanism of the slide member.

With continued reference to fig. 1, the machining device 500 is further provided with air cylinders 501 located two by two at the lateral ends of the pair of slide members 50, the air cylinders 501 being used to pull the pair of slide members 50 apart relative to each other prior to use of the machining device 500.

In some embodiments, the speed of lateral movement (first predetermined speed) of the pair of slide members 50 and the speed of downward movement (second predetermined speed) of the shaping block driving part are linked by providing a specific involute surface of the driving lever 77, and the association is specific to the structural form of the shaping block 80. For example, the shaping block 80 shown in fig. 2 to 3C corresponds to the involute surface shown in fig. 4, and the involute surface shown in fig. 4 enables the lateral movement speed (first predetermined speed) of the pair of slide members 50 and the downward movement speed (second predetermined speed) of the shaping block driving portion to be correlated, so that the pair of slide members 50 and the shaping block driving portion cooperate to obtain the through wave and bulge region corresponding to the shaping block shape in fig. 2 to 3C. The configuration of the shaping block 80 will be discussed below in conjunction with figures 2-3C, and figure 4, respectively, for the involute surface of the drive rod 77.

Referring to fig. 2, the shaping block 80 includes a longitudinal through wave shaping block 81 extending in a longitudinal direction and a bulge region shaping block 82 located at a center of the longitudinal through wave shaping block 81 in the longitudinal direction, the longitudinal through wave shaping block 81 for forming a longitudinal through wave of the film seal layer on the blank sheet, and the bulge region shaping block 82 for forming a bulge region where transverse through waves of the film seal layer intersect on the blank sheet. The longitudinal through wave shaping block 81 tapers only in the lateral dimension in a top-down direction; the bulge area shaping blocks 82 taper in both the lateral and longitudinal dimensions in a top-down direction. That is, in a projection plane defined by the vertical direction and the lateral direction, the projection of the longitudinal through wave shaping block 81 is formed into a bullet-shaped substantially conical shape facing downward; the projection of the bulge region-shaping block 82 is formed into a downward-facing bullet-shaped, generally cone shape in a projection plane defined by the vertical direction and the lateral direction (see fig. 3B), and in a projection plane defined by the vertical direction and the longitudinal direction (see fig. 3C). The processing device 500 is further provided with a shaping base 90 (see fig. 1) located below the longitudinal through wave shaping block 81, the shaping base 90 being located below the shaping block 80, and the top surface of the shaping base 90 having a concave shaping profile 91, the shaping base 90 moving together when the shaping block 80 moves downward. Specifically, a spring is arranged below the shaping substrate 90, the shaping substrate 90 is acted by the spring force when the mold is opened, and moves upwards, the shaping block 80 moves downwards to push the shaping substrate 90 to move downwards when the mold is closed, and the spring is compressed.

Fig. 3A to 3C show the specific structure of the bulge area shaping block 82 in detail. Fig. 3A is a top view of the bulge-area shaping block 82, and fig. 3B and 3C are two side views of the bulge-area shaping block 82. The bulge-area shaping block 82 includes a generally smooth bottom surface 821, the smooth bottom surface 821 has four corners that are symmetrical two by two about a center C of the bottom surface in both the longitudinal and transverse directions, and the bulge-area shaping block 82 further includes four extension segments 822 extending upward from the four corners, respectively. By "smooth bottom surface" is meant that the bottom surface itself does not have an angular edge.

Referring to fig. 3A, bottom surface 821 has four smooth contour lines connected in sequence between four extensions 822, each concave toward the center C of bottom surface 821 at its respective intermediate location, it being understood that "concave" herein refers to concave in a generally horizontal plane. In particular, two of the four contour lines (first contour line 8211) located at both ends of the bottom surface 821 in the longitudinal direction have a first radius of curvature that is concave, and two of the contour lines (second contour line 8212) located at both ends of the bottom surface 821 in the transverse direction have a second radius of curvature that is concave, the first radius of curvature being greater than the second radius of curvature such that the first contour line 8211 is more gentle in radian than the second contour line 8212. Or the first radius of curvature may be equal to the second radius of curvature. The second contour line 8212 has a first length, and the first contour line 8211 has a second length, and the first length is smaller than the second length. It will be appreciated that such a configuration results in the bottom surface 821 having a longitudinal dimension that is less than its transverse dimension.

The bottom surface 821 smoothly transitions to the extension 822. The angle between the horizontal plane and any position of the bottom surface 821 is smaller than the angle between the horizontal plane and the total extending direction of the extension 822, that is, referring to fig. 3B and 3C, the bottom surface 821 is a substantially horizontal arc surface, and the extension 822 extends significantly upward. The overall extension direction of each extension 822 intersects the lateral, longitudinal and vertical directions. The component of the total extension direction of the extension 822 in the horizontal plane is shown by D4 in fig. 3A; the component of the overall direction of extension of the extension 822 in the plane defined by the lateral direction, the vertical direction, is shown by D6 in fig. 3B.

In a bottom view of the bulge region-shaping block 82 (fig. 3A), the main body portion of each extension 822 extends in a direction intersecting both the longitudinal direction D1 and the transverse direction D2, i.e., the D4 direction is not parallel to neither the longitudinal direction D1 nor the transverse direction D2. The component of the extension of the end 8222 of each extension 822 remote from the bottom surface 821 in this figure is D5, D5 being parallel to the transverse direction D2, the body portion smoothly transitioning to the end. In particular, referring to fig. 3B, each extension 822 has a maximum thickness W at a location 8221 that meets the bottom surface 821. Each extension 822 tapers in thickness from a location 8221 that meets the bottom surface 821 to a distal end 8222 that is distal from the bottom surface 821.

In particular, the bottom end of the projection of the bulge region-shaping block 82 in the projection plane defined by the vertical direction D3 and the lateral direction D2 is a curved surface (see fig. 3B), and the bottom end of the projection in the projection plane defined by the vertical direction D3 and the longitudinal direction D1 is a horizontal straight line segment (see fig. 3C). That is, the bottom surface 821 extends smoothly upward in both the lateral direction D2 and upward from the center C of the bottom surface 821, but the bottom surface 821 extends in the direction of the longitudinal direction D1 without having an upward component. The bulge region shaping block 82 is mounted with a guide core having a predetermined punch shape, and the guide core has a hardness greater than other portions of the shaping block 80.

The involute surfaces of the drive rods 77 corresponding to the shaped blocks 80 of fig. 2-3C are shown in fig. 4. Referring to fig. 4, the involute surface includes a first inclined surface 771, a vertical surface 772, and a second inclined surface 773 from top to bottom, wherein the first inclined surface 771, the second inclined surface 773 and the vertical line form an acute angle therebetween, and the vertical surface 772 is parallel to the vertical line. The first inclined surface 771 smoothly transitions to the vertical surface 772, and the first inclined surface 771 extends longer than the second inclined surface 773. The first inclined surface 771 is substantially parallel to the second inclined surface 773. Also, a non-slip drive feature, such as a plurality of ribs extending longitudinally and arranged in a vertical direction, is provided on the first inclined surface 771.

For example, with respect to the shaping block 80 shown in fig. 2-3C, the angle of the first inclined surface 771 with respect to the vertical line, the extension length of the first inclined surface 771, etc. may be specifically set so that the first predetermined speed and the second predetermined speed are specifically correlated so that the pair of sliding members 50 approach each other at the first predetermined speed while the shaping block 80 is moving down at the second predetermined speed, thereby collectively press-shaping the blank plate to obtain a through wave, bulge region corresponding to the shape of the shaping block 80 shown in fig. 2-3C.

It should be noted that, although the involute surface in fig. 4 corresponds to the molding block 80 shown in fig. 2-3C, it is understood that in an actual industrial design, the molding block 80 corresponding to the involute surface in fig. 4 does not necessarily completely coincide with the molding block 80 in fig. 2-3C; the involute surfaces corresponding to the shaped blocks 80 of fig. 2-3C are not necessarily identical to the involute surfaces of fig. 4. In the teaching of the embodiment shown in fig. 2-4, a designer can design other possible configurations of the involute surface, shaping blocks with corresponding relationships to achieve the desired longitudinal wave, bulge area while the pair of sliding members approach each other at a first predetermined speed while the shaping blocks move downward at a second predetermined speed.

For example, it is known in many experiments that the involute surface including the first inclined surface and the first vertical surface can correspond to a bulge area shaping block having a smooth bottom surface and four extension sections, and the total extending direction and the transverse direction, the longitudinal direction and the vertical direction of each extension section intersect, and specifically, the inclination angle, the length setting of the inclined surface and other detailed setting of the shaping block are within a reasonable range; the involute surface comprising the first inclined surface, the first vertical surface, and the second inclined surface can correspond to such a shaped block: the bulge area comprises a bottom surface and four extension sections, the bottom surface is provided with four smooth contour lines which are sequentially connected between the four extension sections, the four contour lines are all concave inwards towards the center of the bottom surface at the middle position, and the inclination angle, the length setting of the inclined plane and other detailed setting of the shaping block are particularly required to be within a reasonable range.

In addition to the embodiment shown in fig. 4, the drive rod may have other involute surfaces. For example: the involute surface may include a concave or convex curved surface; the involute surface can also comprise curved surfaces and plane surfaces which are alternately arranged; the involute profile may include a plurality of curved surfaces having different radii of curvature. The process designer can correspondingly design the involute surface of the driving rod according to the shape of the molding block.

In addition to the embodiment shown in fig. 1, the drive mechanism may have other configurations to achieve a specific correlation of the first and second predetermined speeds with respect to the predetermined shaping profile of the bulge region. For example: the driving mechanism can be fixedly connected with the sliding part and/or connected with the shaping block in a rolling or sliding friction mode; the driving mechanism may include a linkage mechanism that is not fixedly connected, for example, the driving mechanism may include a first driving portion and a second driving portion, the movement directions and/or speeds of the first driving portion and the second driving portion are different, the first driving portion may be connected to the sliding member, and the second driving portion may be connected to the shaping block; the drive mechanism may include a control module that may be programmed to drive the shaping block downward at a second predetermined speed while driving the slide members toward each other at the first predetermined speed.

In some embodiments, the longitudinal through-waves processed by the processing device 500 are small waves, while the transverse through-waves are large waves, both the height and width of the transverse through-waves being greater than the longitudinal through-waves. Correspondingly, the width and height of the protrusions 76 of the platen 60 are greater than the width and height of the longitudinal wave shaping blocks 81. In some embodiments, the cross-sectional profile of the protrusions 76 of the platen 60 is a cambered surface, as is the cross-sectional profile of the longitudinally penetrating wave shaping block 81, and the wave machined by such a device is referred to as a circular arc wave. In other embodiments, the cross-sectional profile of the protrusion 76 of the platen 60 may be substantially triangular, and the cross-sectional profile of the longitudinally-extending wave shaping block 81 may be substantially triangular, and the wave processed by such a device is referred to as a triangular wave.

In other embodiments, the bulge region shaping block may not be provided, so that the involute surface and the longitudinal through wave shaping block correspond. When the blank plate is formed by the longitudinal through wave shaping block, a bulge area is naturally formed at the intersection of transverse and longitudinal waves of the blank plate.

Fig. 1, 5 and 6 illustrate various operating states of a processing apparatus 500 in some preferred embodiments, and the method provided by the present invention will be described with reference to fig. 1, 5 and 6.

When it is desired to machine a longitudinal through wave and bulge region in a blank sheet having a transverse through wave using the machining apparatus 500, the drive mechanism 70 may first be actuated to move the drive mechanism 70 upward to raise the platen 60. Specifically, in the first stage of the upward movement of the driving mechanism 70, the pressure source nitrogen spring 74 stretches, guides and connects the stop lever 75 to slide relative to the middle horizontal plate 73, the pressing plate 60 is stationary, and the driving mechanism 70 moves upward relative to the pressing plate 60; in the second stage of the upward movement of the driving mechanism 70, the pressure source nitrogen spring 74 is at the longest tensile length, the limit portion 751 of the guide connection limit lever 75 abuts against the top end of the intermediate horizontal plate 73, the driving mechanism 70 drives the pressing plate 60 to move upward, and the pressing plate 60 moves upward away from the sliding member 50. Also, at this time, it is also necessary to actuate the cylinder 501 to laterally separate the pair of slide members 50 from each other. The state at this time is shown in fig. 1. In fig. 1 it can be seen that the inner tube 741 of the stretch-sleeve is exposed outside the outer tube 742.

The operator then places the blank sheet into the gap between the slide member 50 and the platen 60 and causes the transverse penetration of the blank sheet to lie just within the receiving area 52 and be correspondingly pressed against by the shape of the tab 76. The drive mechanism 70 is then actuated, causing the drive mechanism 70 to move downwardly. In the first stage of the downward movement of the driving mechanism 70, the pressure source nitrogen spring 74 is locked at the maximum extension length, and the stopper 751 of the guide connection stopper 75 abuts against the top side of the intermediate horizontal plate 73, and the pressing plate 60 moves downward together with the driving mechanism 70 until the pressing plate 60 abuts against the top side of the slide member 50. The state at this time is shown in fig. 5, and it can be seen in fig. 5 that the inner tube 741 of the stretch-sleeve is exposed outside the outer tube 742.

The drive mechanism 70 then continues to move downward, which is the second stage of the drive mechanism 70 moving downward. In the second stage of the downward movement of the driving mechanism 70, in which the pressure source nitrogen spring 74 is compressed, the guide connection stopper 75 penetrates the middle horizontal plate 73 to slide with respect to the middle horizontal plate 73, the driving mechanism 70 can not actuate the pressing plate 60 downward any more, and the second stage of the downward movement of the driving mechanism 70 is mainly for actuating the molding block 80 and the sliding member 50.

In the second stage of the downward movement of the driving mechanism 70, the molding block 80 fixedly installed at the bottom end of the vertical plate 72 of the driving mechanism 70 moves downward at a second predetermined speed together with the driving mechanism 70 while the involute surface of the driving lever 77 of the driving mechanism 70 contacts and pushes the force-receiving pin 51 of the sliding member 50, the involute surface being shaped such that the pair of sliding members 50 approach each other at a non-uniform first predetermined speed when the driving mechanism 70 moves downward at the second predetermined speed. Wherein the second predetermined speed and the first predetermined speed are specifically related but not equal, "specifically related" means that the association relationship of the second predetermined speed and the first predetermined speed is specifically set for the specific form of the shaping block 80. Preferably, the first predetermined speed and the second predetermined speed are not even in a linear relationship, that is to say the first predetermined speed and the second predetermined speed may not increase or decrease in equal proportion. In a second stage of the downward movement of the drive mechanism 70, the shaped base 90, the shaped block 80, and the pair of slide members 50 collectively squeeze the blank plate to obtain a predetermined longitudinal through wave and bulge area. The running speeds of the parts of the extruded blank sheet moving in different directions are specifically related so that the forming process is particularly suitable for film sealing layers having the predetermined corrugated shape.

The state at the end of the second phase of the downward movement of the drive mechanism 70 is shown in fig. 6. At this point the pair of slide members 50 are in the closest position relative to each other, the shaping block 80 is pressed between the pair of slide members 50 and against the top side of the shaping base 90. At this point the pressure source nitrogen spring 74 is at its shortest position, and it can be seen that the inner tube is completely received within the outer tube 742. The stopper 751 of the guide connection stopper 75 at this time abuts against the bottom side of the main horizontal plate 71.

In the first stage of the downward movement of the drive mechanism 70, the drive mechanism 70 as a whole may have a uniform downward movement speed. In the second stage of the downward movement of the driving mechanism 70, the downward movement speed of the driving mechanism 70, i.e., the speed of the driven shaping block 80 (second predetermined speed) may also be variable, such as a gradual deceleration speed change, due to the reaction force of the pressure source nitrogen spring 74; alternatively, in other embodiments, the control system controlling the downward movement of the drive mechanism 70 may be preprogrammed and execute such operating logic: the force applied to the driving mechanism 70 is gradually increased in the second stage, and the increased force and the reaction force of the pressure source nitrogen spring 74 can be balanced, so that the driving mechanism 70 still keeps descending at a constant speed in the second stage, that is, the speed (second predetermined speed) of the driven shaping block 80 can still be substantially constant. Whether or not the downward movement speed of the shaping block 80 in the second stage is uniform, the movement speed of the slide member 50 (first predetermined speed) is non-uniform and not equal to the second predetermined speed, or even not in a linear relationship with the second predetermined speed.

It should be noted that, the "speed" referred to in the present invention should be understood as a magnitude of a speed value of the speed, for example, the "first predetermined speed is not equal to the second predetermined speed" referred to in the present invention refers to a speed value of the first predetermined speed of the transient is not equal to a speed value of the second predetermined speed of the transient at any time node.

Thereafter, the operator may actuate the driving mechanism 70 again to move up again while driving the air cylinder 501 to move the pair of sliding members 50 away from each other so that the processing apparatus 500 is restored to the state shown in fig. 1, so that the operator can take out the processed film sealing layer.

The method of the invention can press the pressing plate in the first stage of the downward movement of the driving mechanism after the blank plate is placed at the preset position; the second stage of the downward movement of the drive mechanism drives both the shaping block and the slide member, the shaping block drive and the slide member drive being fixed relative to each other, preferably the speed of the shaping block being driven can also be different from the speed of the slide member being driven, more preferably even the shaping block speed and the slide member speed may not be in a fixed ratio (e.g. by involute profile or programmed control logic), the shaping block and slide member having different speeds cooperating to form a predetermined shape on the blank sheet. The bulge area of the film sealing layer formed by the process has uniform thickness and excellent performance.

It should be noted that in order to facilitate the driving mechanism being able to perform driving in different directions (e.g. driving the shaping block in a vertical direction and driving the sliding member in a horizontal direction), it is generally preferred that the shaping block driving part and the sliding member driving part are actuated separately, and such an arrangement may result in that the shaping block driving part and the sliding member driving part cannot be accurately associated, resulting in poor performance of the film sealing layer cooperatively formed by the driven shaping block and the sliding member, whereas the present invention can enhance performance of the formed film sealing layer by fixing the shaping block driving part and the sliding member driving part with respect to each other such that they are accurately associated. On the other hand, the waviness of the film sealing layer, especially the bulge area, may be complicated in shape, and if the shaping block driving part and the sliding part driving part are cooperatively shaped at the same speed, the obtained film sealing layer may have uneven thickness and poor performance, and then preferably, the invention integrally drives the shaping block and the sliding part, and simultaneously ensures that the speeds of the driving block and the sliding part are unequal, even the speeds of the driving block and the sliding part are not in a linear relation, so that the thickness of the finally shaped film sealing layer is uniform and the performance is superior.

The above embodiments are for illustrative purposes only and are not intended to be limiting. Those skilled in the art can modify the above embodiments, and the modification results are within the scope of the present invention.
