Description

Technical Field

[0001] The invention relates to the technical field of cutting devices, and in particular to a cutting device for a laminate sample with a reinforcement plate. Background Art

[0002] Composite laminates have been widely used in aerospace, automobile manufacturing, wind turbine blades and other fields due to their high specific strength, high specific stiffness and excellent corrosion resistance. In practical applications, in order to evaluate the mechanical properties of composite materials, it is usually necessary to prepare high-precision and stable specimens through standardized specimen cutting processes. However, composite laminate specimens with reinforcement plates face many challenges during cutting due to their complex structure, especially the design of the suspended part of the laminate has an important impact on the cutting quality.

[0003] In a typical design, composite laminate specimens with reinforcement plates are usually not bonded to the reinforcement plates in other areas. The purpose of the unbonded design is to avoid interference of the reinforcement plates on the mechanical properties test in the gauge area and ensure the accuracy of the test data. However, this design also causes a series of problems during the cutting process. Due to the lack of support from the reinforcement plates in other areas except the reinforcement plate area, a suspended state is formed between the lower surface and the cutting platform. The suspended part is extremely susceptible to external vibrations during the cutting process, further causing defects such as material delamination and dislocation. These defects not only reduce the cutting quality, but may also have an adverse effect on the subsequent mechanical properties test results. Summary of the invention

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0033] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0034] Reference Figure 1-Figure 9 As shown, a laminate sample cutting device with a reinforcement plate includes a workbench 1, a negative pressure fixing platform 2 is provided on the workbench 1, a cover plate 3 is installed on the negative pressure fixing platform 2, the negative pressure fixing platform 2 can form a strong adsorption force to prevent the sample from moving during the cutting process, the negative pressure adsorption area needs to cover the entire laminate 4 area to ensure that all contact surfaces are evenly stressed; a flexible rubber pad is used to seal between the laminate 4 and the cover plate 3 to reduce gas leakage of the adsorption system.

[0035] A laminate 4 is placed on the top of the cover plate 3. Reinforcement plates are arranged on the upper and lower sides of the laminate 4 itself. The gauge area is set between the reinforcement plates. A pad 5 is bonded to the gauge area of ​​the laminate 4. The material of the pad 5 is consistent with that of the reinforcement plate, including the matrix resin, fiber type and layer structure, to ensure that its mechanical properties are consistent with those of the laminate 4, avoiding mechanical interference caused by material differences;

[0036] The width of the pad 5 is designed to be 80% of the width of the gauge area, which not only ensures sufficient support area but also facilitates the removal of the pad 5 after cutting;

[0037] The thickness of the spacer block 5 matches the thickness of the laminate 4 to provide uniform support.

[0038] Adhesive Selection:

[0039] Use of an easily removable flexible adhesive, such as a water soluble or hot melt adhesive, ensures that the spacer 5 can be quickly removed after cutting.

[0040] The adhesive must have sufficient initial strength to fix the pad 5 during the cutting process and prevent it from falling off due to vibration or cutting force.

[0041] Adhesive Application Method:

[0042] Apply adhesive evenly on the upper and lower surfaces of the laminate 4 gauge area to ensure that the pad 5 fits tightly against the laminate 4 without bubbles or gaps.

[0043] The addition of the pad 5 effectively supports the suspended part of the gauge area, reduces cutting vibration, and reduces delamination and misalignment; after cutting, the adhesive can be easily removed by heating or dissolving without damaging the surface of the laminate 4.

[0044] A fixing frame 6 is also provided on the negative pressure fixing table 2, and a cutting assembly 9 is provided on the fixing frame 6. The cutting assembly 9 is used to cut the four sides of the laminate 4 to obtain a sample of a required size, confirm that the laminate 4 is completely fixed on the cover plate 3, and check whether the pad 5 is tightly bonded to the gauge area of ​​the laminate 4; adjust the parameters of the cutting assembly 9, including the cutting speed, tool feed rate and cutting depth, to adapt to the characteristics of the composite material and avoid damage caused by excessive cutting force.

[0045] Also includes:

[0046] The positioning assembly includes a mounting plate 7 rotatably connected to the fixing frame 6, a first hydraulic rod 81 is disposed at the bottom of the mounting plate 7, and a positioning plate 8 is disposed at the bottom end of the first hydraulic rod 81;

[0047] The jacking assembly 13 is arranged on the cover plate 3 and is used to support the bottom of the laminate 4, mainly supported on the outer suspended area of ​​the reinforcing plate;

[0048] The clamping assembly 10 is arranged on the cutting assembly 9 and is used to clamp the surface of the laminate 4 or the reinforcing plate. The clamping assembly 10 rotates together with the cutting assembly 9. Each time when cutting, the clamping assembly 10 is pressed against the laminate 4 or the reinforcing plate to further strengthen the fixation and avoid vibration of the laminate 4 when cutting.

[0049] The waste cleaning component 11 is arranged on the cutting component 9 and is used to clean the cut waste. Since the four sides are directly cut off during cutting, the cut waste can be removed by the waste cleaning component 11 after one side is cut.

[0050] The receiving bin 14 is arranged between the negative pressure fixing platform 2 and the cover plate 3, and a through hole is opened at the bottom thereof, and the top end of the receiving bin 14 is closely attached to the cover plate 3. The receiving bin 14 is also movable, and is adjusted according to the cutting position so that the receiving bin 14 is located at the bottom of the cutting position and is close to the waste side. When cutting, a certain amount of debris will be generated, and these debris will move downward through the negative pressure hole, and the receiving bin 14 can receive the debris generated by the cutting;

[0051] The plugging component 15 is arranged in the receiving bin 14. When cutting, the plugging component 15 can move together with the cutting component 9. The plugging component 15 moves along the bottom of the receiving bin 14, thereby gradually plugging the bottom through hole of the receiving bin 14. This is mainly because when cutting, especially in the cut-off state, the gap generated at the cutting point, as well as the vibration, heat, and debris generated by the cutting, may affect the sealing of the suction cup, resulting in air leakage. Once air leakage occurs, the negative pressure inside the vacuum suction cup will decrease, thereby weakening the adsorption force, which may not only affect the processing accuracy and efficiency, but may also cause the workpiece to be in the process of processing. Movement or falling off may occur, causing safety hazards. Therefore, it is necessary to move the sealing component 15 synchronously during cutting to seal along the cutting line to avoid air leakage. It is also possible to seal after the cutting is completed. Here, since air leakage may occur, it is necessary to turn on the vacuum pump to evacuate air before sealing to maintain a certain negative pressure state and provide sufficient adsorption force to prevent the laminate 4 from falling off. After the cutting is completed, the negative pressure hole at the bottom of the cut waste will be sealed. After the sealing is completed, the bottom of the cut waste will also lose the negative pressure attraction, and it can move on the cover plate 3, so as to be cleaned up by the waste cleaning component 11.

[0052] In one embodiment, the cutting assembly 9 includes a second hydraulic rod 91 disposed on the mounting plate 7, a support frame 92 is disposed at the movable end of the second hydraulic rod 91, a crossbeam 93 is disposed at the bottom of the support frame 92, a cutting knife 94 is slidably disposed at the bottom of the crossbeam 93, and the cutting knife 94 uses mechanical cutting, laser cutting or water jet cutting methods to complete precise cutting of the sample according to process requirements, and the waste cleaning assembly 11 is disposed on the crossbeam 93.

[0053] In one embodiment, the waste cleaning assembly 11 includes a first lever arm 111 rotatably disposed on the crossbeam 93, a second lever arm 112 is rotatably disposed at one end of the first lever arm 111, a third lever arm 113 is rotatably disposed at one end of the second lever arm 112, a rotating block 114 is rotatably disposed at one end of the third lever arm 113, a cleaning suction cup 115 is disposed on the rotating block 114, and a waste bin 12 is also disposed around the cover plate 3;

[0054] After the cutting is completed, the cleaning suction cup 115 can be moved by the robot arm so that the cleaning suction cup 115 is closely attached to the side wall of the laminate 4, and then moved to the top of the waste bin 12 to put the fertilizer down.

[0055] In one embodiment, the lifting assembly 13 includes two mounting frames 131 disposed on the cover plate 3, a slide bar 132 is disposed in the mounting frames 131, a fixed sleeve 133 is disposed between the two mounting frames 131, a lifting top plate 134 is movably disposed in the fixed sleeve 133, connecting rods 135 are further disposed at both ends of the fixed sleeve 133, and a transverse sliding block 136 sleeved on the slide bar 132 is disposed at one end of the connecting rod 135 away from the fixed sleeve 133;

[0056] In order to support the laminate 4 on the outside of the reinforcing plate, after the laminate 4 is fixed by negative pressure suction through the negative pressure fixing platform 2, the jacking components 13 on both sides are moved to the bottom of the suspended area outside the laminate 4, and then the lifting top plate 134 is raised to support it at the bottom of the suspended area, giving the area a certain supporting force.

[0057] In one embodiment, the clamping assembly 10 includes a third hydraulic rod 105 fixed on the cutting assembly 9, two first fixed pressing plates 101 are arranged at the bottom end of the third hydraulic rod 105, a cutting gap is formed between the two first fixed pressing plates 101, movable pressing plates 102 are slidably arranged at both ends of the first fixed pressing plates 101, a lifting assembly 103 is arranged at one end of the movable pressing plate 102 away from the first fixed pressing plate 101, the movable pressing plate 102 is movably connected to the lifting assembly 103, and a second fixed pressing plate 104 is arranged at the bottom end of the lifting assembly 103;

[0058] The lifting assembly 103 includes a vertical plate 1031 connected to the second fixed plate 104, a guide rod 1032 is arranged in the vertical plate 1031, a lifting slider 1033 sleeved on the guide rod 1032 is arranged at one end of the movable plate 102 away from the first fixed plate 101, and a return spring 1034 sleeved on the guide rod 1032 is arranged between the lifting slider 1033 and the bottom end of the vertical plate 1031;

[0059] When cutting the laminate 4, the cutting position is first pressed. If it is located in the suspended area outside the reinforcing plate, the jacking assembly 13 can be used to fix and clamp the laminate 4 to reduce the vibration force generated at this position during cutting. If it is located at the reinforcing plate, since the reinforcing plate itself is tightly attached to the cover plate 3, it is directly attracted by the negative pressure, and then it is pressed at the top reinforcing plate through the clamping assembly 10, thereby completing the secondary fixation of the entire laminate 4.

[0060] The clamping assembly 10 can also be adjusted according to the size of the laminate 4, especially when clamping the side with the reinforcement plate, first pull the movable pressure plate 102 to both sides so that the second fixed pressure plate 104 exceeds the area of ​​the reinforcement plate. At this time, the movable pressure plate 102 is pushed downward by the third hydraulic rod 105, and the movable pressure plate 102 drives the first fixed pressure plate 101 and the second fixed pressure plate 104 to move downward together. First, the second fixed pressure plate 104 will first contact the laminates 4 on both sides, and then the movable pressure plate 102 drives the first fixed pressure plate 101 to continue to move downward. At this time, the reset spring 1034 will be compressed by the lifting slider 1033 until the first fixed pressure plate 101 and the movable pressure plate 102 are pressed tightly against the reinforcement plate, and the second fixed pressure plate 104 will be tightly attached to the laminate 4 under the elastic force of the reset spring 1034 to complete the fixation;

[0061] On the side without the reinforcing plate, that is, when there is only the laminate 4, the pressing is the same, except that the second fixed pressing plate 104 will first contact the laminate 4, and then the first fixed pressing plate 101 and the movable pressing plate 102 continue to move downward until they are also pressed against the surface of the laminate 4.

[0062] In one embodiment, the receiving bin 14 includes a first receiving frame 141 disposed between the negative pressure fixed platform 2 and the cover plate 3, and second receiving frames 142 are slidably disposed at both ends of the first receiving frame 141, and through holes are provided at the bottom ends of the first receiving frame 141 and the second receiving frame 142, and a fixing plate 143 fixed to the side wall of the first receiving frame 141 is disposed between the two second receiving frames 142, and a fourth hydraulic rod 144 is further disposed in the cover plate 3, and the movable end of the fourth hydraulic rod 144 is connected to the fixing plate 143, and an adjusting component for driving the second receiving frame 142 to move is disposed in the fixing plate 143, and a blocking component 15 is disposed in the second receiving frame 142, and the blocking component 15 is slidably connected to the second receiving frame 142 and the first receiving frame 141 respectively;

[0063] The adjustment assembly includes a driving gear 145 rotatably disposed in a fixed plate 143, a driven gear 146 meshing with the driving gear 145, a bidirectional threaded rod 147 disposed in the driven gear 146, and a guide plate 148 sleeved on the bidirectional threaded rod 147 disposed in the second receiving frame 142;

[0064] The receiving bin 14 itself is movable, and the receiving bin 14 is moved to the cutting position and close to the cut portion to facilitate the subsequent sealing of the bottom of the portion; at the same time, its length is also adjustable, mainly to adapt to the size of the laminate 4; when in use, the receiving bin 14 is first adjusted according to the size of the laminate 4, and the active gear 145 drives the driven gear 146 to rotate, and the driven gear 146 drives the bidirectional threaded rod 147 to rotate, and the bidirectional threaded rod 147 drives the second receiving frames 142 at both ends to move to both ends, and then according to the cutting position, the receiving bin 14 is pushed inward by the fourth hydraulic rod 144.

[0065] In one embodiment, the blocking assembly 15 includes a roller shaft 151 disposed in the second receiving frame 142, and driving blocks 152 are rotatably disposed at both ends of the roller shaft 151. The driving blocks 152 are slidably connected to the first receiving frame 141 and the second receiving frame 142. A baffle 153 is also disposed between the two driving blocks 152, and the top end of the baffle 153 is tightly attached to the cover plate 3. A spring is disposed on the roller shaft 151, and a sealing strip for blocking the through hole is sleeved on the spring;

[0066] During cutting, or after cutting is completed, the driving block 152 is moved along one end of the receiving bin 14 to the other end, so that the sealing strip blocks the through hole at the bottom of the receiving bin 14, so that the bottom of the cut part loses the negative pressure suction, so that the cut part can be cleaned up in time through the waste cleaning component 11.

[0067] In one embodiment, a first support plate 154 is provided in the side wall of the first supporting frame 141, a second support plate 155 is slidably provided in the first support plate 154, one end of the second support plate 155 is connected to the second supporting frame 142, a long hole is provided at the top of the first support plate 154, a first slide groove is provided at the bottom of the first support plate 154, a second slide groove aligned with the long hole is provided at the top of the second support plate 155, a first limiting slider 1521 passing through the long hole and sliding in the first slide groove is provided in the driving block 152, and a second limiting slider 1522 sliding in the second slide groove is provided at the bottom end of the driving block 152;

[0068] This is mainly because after the receiving bin 14 changes its length, such as when the length is increased, the second support plate 155 will move outward with the second supporting frame 142, and the second support plate 155 will also slide along the first support plate 154. Later, when blocking, the driving block 152 slides along the support plate, and under the cooperation of the first limiting slider 1521 and the first slide groove, the driving block 152 can slide along the second support plate 155 at the beginning, and the second limiting slider 1522 at the bottom is in a suspended state. Later, when it moves to the connection between the first support plate 154 and the second support plate 155, the second limiting slider 1522 at the bottom will slide along the second slide groove. Movement, mainly after moving to the middle of the first support plate 154, there is no second support plate 155 here, and the driving block 152 can still be limited and slid by the second limiting slider 1522. At the same time, when the driving block 152 moves, it will pull the sealing strip, so that the sealing strip slides along the bottom of the receiving bin 14 to seal the through hole at the bottom, and the baffle 153 at the front end of the sealing strip will also move together. The top end of the baffle 153 is connected to the inner top surface of the cover plate 3, and the bottom end is close to the bottom of the receiving bin 14. It is mainly used for cutting and sealing. When cutting, it moves together to seal the cutting seam to avoid air leakage.

[0069] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
