Description

Technical Field

[0001] The invention relates to the technical field of strength detection, and in particular to a high-efficiency strength detection device for aluminum-plastic panels. Background Art

[0002] Aluminum-plastic panels (ACPs) are composite materials made by laminating aluminum alloys and plastics (usually polyethylene). They are widely used in applications such as architecture, billboards, traffic signs, and home decoration. The panel's strength is a key factor in determining its performance and reliability. This strength directly impacts the panel's impact resistance, bending resistance, and tensile strength in practical applications. To ensure the panel's stability during manufacturing, transportation, installation, and use, rigorous strength testing is essential.

[0003] The utility model patent (publication number: CN220380898U) discloses an aluminum-plastic panel strength testing machine, comprising a base and a housing. L-shaped support plates are symmetrically mounted on the base. A fixing plate is fixedly mounted on one side of the support plates, which are close to each other. A sliding rod extends through the fixing plate. A pressure block is fixedly mounted at the bottom of the sliding rod, and a pressure plate is fixedly mounted at the top of the sliding rod. A spring is installed on the outer wall of the sliding rod between the pressure block and the pressure plate. A hydraulic cylinder is fixedly mounted at the top of the housing, and a lifting plate is fixedly mounted at the bottom of the hydraulic cylinder. A pressure sensor is fixedly mounted in the middle of the bottom of the lifting plate, and a pressure seat is mounted at the bottom of the pressure sensor. This machine facilitates the fixing and removal of panels, has a simple structure, and offers low production and operating costs.

[0004] The strength of aluminum-plastic panels mainly includes tensile strength testing and impact strength testing. The mainstream strength testing equipment on the market are the same as the above-mentioned patents, and can only perform tensile strength testing or impact strength testing. During the impact strength testing process, the impact load generally needs to adjust the impact load range according to the material characteristics of the aluminum-plastic panel. Excessive impact force will cause the material to break directly or cause irreversible damage, and it is impossible to accurately evaluate its impact resistance in normal use; if the impact force is too small, it cannot stimulate the true performance of the material, resulting in optimistic test results. Therefore, when conducting impact strength testing of aluminum-plastic panels, the equipment needs to be debugged to ensure that the test is more in line with the actual load-bearing capacity of the material. In the actual testing process, it is usually necessary to conduct continuous testing of aluminum-plastic panels of different specifications, and the equipment needs to be debugged each time, which leads to low testing efficiency.

Therefore, after the tensile strength test is completed, the material is automatically unloaded, and the influence of the aluminum-plastic panel itself on the fixed splint can be eliminated. The equipment can continuously perform subsequent impact resistance tests and is simple to operate. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0030] Example 1, as Figure 1-Figure 7 As shown, a high-efficiency strength testing device for aluminum-plastic panels includes an operating platform 1, a transverse guide rail 2 is fixedly mounted on the top of the operating platform 1, two sets of detection swing rods 4 are rotatably mounted on the top of the operating platform 1, and synchronous wheels 41 are fixedly mounted at the rotation centers of the two sets of detection swing rods 4. The two sets of synchronous wheels 41 are meshed with each other. The detection swing rods 4 are located above the transverse guide rail 2. A sliding opening 43 is formed inside the detection swing rods 4, and multiple groups of buffer components are arranged inside the sliding opening 43.

[0031] The interior of the sliding opening 43 is slidably connected to a fixed splint 5, and a movable splint 54 is sleeved on the bottom of the fixed splint 5. A top spring 55 is provided between the movable splint 54 and the fixed splint 5. A clamping block 57 is provided between the fixed splint 5 and the movable splint 54. A lifting and lowering transverse guide rod 53 is provided at the bottom of the fixed splint 5. The top of the transverse guide rail 2 is designed in a stepped manner, and the movable splint 54 presses against the top of the transverse guide rail 2.

[0032] A connecting rod 6 is rotatably installed on the top of the fixed splint 5, a vertical guide rail 3 is fixedly installed on the top of the operating platform 1, an impact head 7 is slidably connected to the top of the vertical guide rail 3, the connecting rod 6 is hinged on the impact head 7, and two groups of impact clamping assemblies are fixedly installed on the top of the operating platform 1, and the two groups of impact clamping assemblies are symmetrically distributed about the vertical guide rail 3.

[0033] The buffer assembly includes an outer buffer tube 44 fixedly mounted on the outside of the detection rocker arm 4, and a buffer slide 45 is slidably connected to the inside of the outer buffer tube 44. The buffer slide 45 passes through the sliding opening 43. The buffer slide 45 is tilted on the side close to the rotation center of the detection rocker arm 4, and a buffer spring 46 is arranged between the buffer slide 45 and the inner wall of the outer buffer tube 44.

[0034] Clamping: Clamp two aluminum-plastic panels of the same specification, place the aluminum-plastic panel to be tested for tensile strength horizontally on two sets of movable clamps 54, then control the clamping block 57 to descend, and the clamping block 57 clamps the two ends of the aluminum-plastic panel; vertically clamp the aluminum-plastic panel to be tested for impact strength on two sets of impact clamping components to complete the clamping.

[0035] Detection: Start the equipment, the two groups of detection pendulum rods 4 swing synchronously in opposite directions, the two groups of detection pendulum rods 4 give thrust to the fixed splint 5 through the sliding mouth 43, under the action of the transverse guide rod 53 and the transverse guide rail 2, the fixed splint 5 can slide in a straight line, thereby giving tensile strength tension to both ends of the aluminum-plastic panel. When the aluminum-plastic panel is broken, the two groups of detection pendulum rods 4 quickly swing away, and at the same time the detection pendulum rod 4 realizes the driving load and swings only under the action of inertia force. The detection pendulum rod 4 drives the fixed splint 5 to swing, and under the guidance of the transverse guide rod 53, the fixed splint 5 will slide along the sliding mouth 43 in the direction away from the swing center of the detection pendulum rod 4. When the movable splint 54 moves from the high position of the transverse guide rail 2 to the low position, the movable splint 54 slides downward under the action of the top spring 55, and the movable splint 54 moves away from the clamping block 57, and the aluminum-plastic panel is released. After the automatic unloading is completed, the fixed splint 5 moves to the buffer assembly position, and the fixed splint 5 pushes the buffer slide 45 to slide in the outer buffer tube 44 through the inclined surface of the buffer slide bar 45. The buffer slide bar 45 squeezes the buffer spring 46, and the buffer slide bar 45 slows down the inertial sliding force generated by the fixed splint 5. The greater the tensile strength of the aluminum-plastic plate, the greater the load applied to the detection pendulum 4. Therefore, after the aluminum-plastic plate breaks, the inertial force generated by the detection pendulum 4 is greater, the more buffer assemblies are moved by the fixed splint 5, and the further away the fixed splint 5 is from the rotation center of the detection pendulum 4. When the fixed splint 5 is away from the corresponding buffer slide bar 45, the buffer spring 46 pushes the buffer slide bar 45 to extend into the sliding mouth 43 again. The buffer slide bar 45 limits the fixed splint 5 from moving toward the rotation center of the detection pendulum 4, completing the automatic tensile strength test.

[0036] At this time, the transverse guide rod 53 is controlled to slide upward, and the transverse guide rod 53 moves away from the transverse guide rail 2. Then, a load is applied to the detection pendulum rod 4 again, and the load is opposite to the tensile strength detection load. The two groups of detection pendulum rods 4 are quickly brought together at a certain speed. When the detection pendulum rod 4 swings, it drives the fixed splint 5 to swing. The fixed splint 5 drives the impact head 7 to slide along the vertical guide rail 3 through the connecting rod 6, and slides toward the direction of the aluminum-plastic plate for impact strength detection. The impact head 7 impacts the aluminum-plastic plate at a certain speed. It should be noted that when the detection pendulum rods 4 are brought together, the impact head 7 will give the fixed splint 5 a thrust toward the rotation center of the detection pendulum rod 4 through the connecting rod 6. The buffer slide bar 45 limits the fixed splint 5 from moving toward the rotation center of the detection pendulum rod 4, so the impact load can be applied stably. The greater the tensile strength of the aluminum-plastic panel, the greater the load applied by the detection pendulum 4. Therefore, after the aluminum-plastic panel breaks, the greater the inertial force generated by the detection pendulum 4, the more buffer components are moved by the fixed splint 5, the farther the fixed splint 5 is from the rotation center of the detection pendulum 4, the greater the linear speed of the fixed splint 5, and the greater the impact speed of the impact head 7. The anti-impact load can be adaptively adjusted according to the detection load to keep the anti-impact load within an appropriate range.

[0037] The adjustment principle is as follows: tensile strength is the maximum stress a material can withstand during stretching and generally reflects its toughness and resistance to rupture. Impact resistance is the material's ability to withstand instantaneous external impact. Both are important indicators of material performance. Although there are differences, generally, higher tensile strength results in better impact resistance. By automatically adjusting the impact force to suit the tensile strength of different materials, impact testing can be more accurate, avoiding excessive or insufficient impact forces and thus obtaining more representative performance data.

[0038] In summary, the present invention not only realizes the integration of tensile strength and impact strength detection, but also converts the swing displacement of the tensile strength detection pendulum rod 4 into the loading of the impact distance of the impact head 7, and at the same time uses the inertial force formed by the tensile strength load to adaptively adjust the subsequent impact strength. Secondly, the reset of the detection pendulum rod 4 is realized through the impact displacement distance of the impact head 7. The tensile strength and impact strength detection can be realized at one time only by detecting the expansion and closing of the pendulum rod 4, and there is no need to adjust the impact load, which greatly simplifies the detection process and the detection time is only one-fifth of the previous time.

[0039] Embodiment 2, based on the above embodiment, further includes that a plurality of groups of rollers 21 are provided at the high position of the transverse guide rail 2, and the rollers 21 extend to the difference between the high position and the low position. Through the setting of the rollers 21, the influence of the friction between the movable splint 54 and the high position of the transverse guide rail 2 on the tensile load can be eliminated.

[0040] Embodiment 3, based on the above embodiment, further includes: the internal thread of the fixed splint 5 is connected with a clamping bolt 56, the clamping block 57 is rotatably installed at the bottom of the clamping bolt 56, and a guide column 58 is provided on the top of the clamping block 57, and the guide column 58 passes through the fixed splint 5.

[0041] The bottom of the clamping block 57 and the top of the movable clamping plate 54 are both provided with serrated grooves to enhance the clamping force.

[0042] When clamping, place the aluminum-plastic panel on the movable clamping plate 54, then screw down the clamping bolt 56, which drives the clamping block 57 to descend, and the clamping block 57 presses the aluminum-plastic panel tightly against the movable clamping plate 54, making clamping convenient.

[0043] Embodiment 4, based on the above embodiment, further includes: a card groove is provided on the inner wall of the sliding mouth 43, a snap ring 51 is provided on the outer side of the fixed splint 5, the snap ring 51 is slidably connected in the card groove, a storage hole is provided inside the fixed splint 5, the transverse guide rod 53 is inserted into the storage hole, a lifting screw 52 is fixedly installed on the top of the transverse guide rod 53, a threaded hole is provided on the top of the storage hole, and the lifting screw 52 is threadedly connected in the threaded hole.

[0044] After the tensile strength test is completed, the lifting screw 52 is screwed upward, and the lifting screw 52 drives the transverse guide rod 53 to rise and enter the storage hole. The transverse guide rod 53 is away from the transverse guide rail 2, so that during the subsequent impact strength test, the detection rocker arm 4 can stably drive the fixed splint 5 to swing without being interfered by the transverse guide rail 2.

[0045] Example five, based on the above example, further includes: synchronization wheels 41 are provided on the top and bottom of the detection rocker arm 4, a driving wheel 42 is fixedly installed on the bottom of one group of detection rocker arms 4, a detection hydraulic cylinder 9 is fixedly installed on the bottom of the operating platform 1, and a driving gear rod 10 is fixedly installed on the telescopic end of the detection hydraulic cylinder 9, and the driving gear rod 10 is engaged with the driving wheel 42.

[0046] By injecting hydraulic oil into the detection hydraulic cylinder 9, as the hydraulic oil is continuously pressurized, the detection rocker arm 4 is given a continuous swinging force through the driving gear rod 10 and the driving wheel 42, thereby continuously applying a pulling force to the aluminum-plastic panel. It should be noted that the hydraulic system used in the present invention is a hydraulic system with pressure feedback. When the pressure is released instantly, the hydraulic system stops running, so that the detection rocker arm 4 only swings under the action of inertia.

[0047] When conducting an impact load test, an instantaneous driving force is given to the detection pendulum rod 4 to make the detection pendulum rod 4 swing rapidly within a certain angle, apply load to the impact head 7, and cancel the hydraulic pressure after the load is applied. The advantage of this arrangement is that, due to different specifications of aluminum-plastic panels, the final position of the fixed splint 5 is different. The closer to the swing center of the detection pendulum rod 4, the larger the swing angle of the detection pendulum rod 4 is required to ensure that the impact head 7 can stably impact the aluminum-plastic panel. The continuous loading time is long, so it is necessary to apply an instantaneous load to make the initial swing speed of the detection pendulum rod 4 the same. When the impact head 7 is not in contact with the aluminum-plastic panel, it is unloaded, so that the impact head 7 impacts the aluminum-plastic panel under the action of inertia force, and there will be no situation where the loading is continued after the impact is completed.

[0048] Embodiment 6, based on the above embodiment, further includes that the impact clamping assembly includes an impact clamping column 8 fixedly installed on the top of the operating platform 1, a clamping groove is vertically opened inside the impact clamping column 8, an impact clamping plate 82 is provided inside the clamping groove, and two groups of clamping bolts 81 are threadedly connected to the outer side of the impact clamping column 8, and the two groups of clamping bolts 81 are both rotatably installed on the impact clamping plate 82.

[0049] By tightening the two sets of clamping bolts 81 , the impact clamping plate 82 vertically clamps the aluminum-plastic panel on the impact clamping column 8 .

[0050] Embodiment 7, on the basis of the above embodiment, further includes: a lead screw 31 is rotatably installed inside the vertical guide rail 3, the outer side of the lead screw 31 is threadedly connected to a ball slide 32, the ball slide 32 is slidably connected in the vertical guide rail 3, a connecting threaded hole 33 is provided at the top of the ball slide 32, a slot is provided at the bottom of the impact head 7, the internal thread of the slot is connected to a connecting bolt 71, the connecting bolt 71 can be threadedly connected in the connecting threaded hole 33, the spiral pitch of the outer surface of the lead screw 31 is 100mm-150mm, and a rotary handle is provided at the end of the lead screw 31 away from the horizontal guide rail 2.

[0051] Through the design of this embodiment, when the hydraulic system fails, the impact head 7 is fixed to the ball slide 32 by the connecting bolt 71, and by rotating the screw 31, the screw 31 drives the ball slide 32 to slide, and the ball slide 32 drives the impact head 7 close to the transverse guide rail 2. The impact head 7 gives a thrust to the fixed splint 5 through the connecting rod 6, and the fixed splint 5 slides along the transverse guide rail 2 through the transverse guide rod 53, so that the aluminum-plastic panel can be manually applied with a load, and the tensile strength test can be achieved in the event of power failure or hydraulic system failure.

[0052] When only the tensile strength test is required, the impact head 7 is fixed to the ball slide 32 by the connecting bolt 71. When the aluminum-plastic plate is broken, since the spiral pitch of the outer surface of the screw 31 is 100mm-150mm, which is a large pitch, when the detection pendulum 4 swings by inertia, a pulling force is applied to the impact head 7 by the fixed clamping plate 5 and the connecting rod 6. The impact head 7 will drive the ball slide 32 to slide, and the ball slide 32 will drive the screw 31 to rotate. However, under the action of the spiral of the screw 31, a certain buffering force can be given to prevent the detection pendulum 4 from swinging too large an angle when only the tensile strength test is carried out. This not only improves the safety of the device, but also makes the reset efficiency of the detection pendulum 4 higher.

[0053] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
