Description

Technical Field

[0001] This utility model belongs to the field of board testing technology, and more specifically, it relates to a device for testing the bending resistance of boards used in furniture processing. Background Technology

[0002] The bending resistance of a sheet material often determines its application. Testing primarily involves applying force to the sheet material using a force-applying device, causing it to bend, to determine its bending resistance. Common sheet bending resistance testing devices are often located in laboratories, requiring the sample to be transported for testing, which is time-consuming. Furthermore, if the test fails after using up all the material, it is cumbersome to retrieve more material for testing.

[0003] Patent CN117517090A discloses a device for testing the bending resistance of wood panels used in wooden furniture processing. It includes a bottomless box with a fixed base detachably connected to its lower end. A fixed limiting shaft is fixedly connected to the fixed base. A rectangular frame is slidably connected inside the bottomless box, with a telescopic device at one end. The rectangular frame includes a rectangular frame body, within which are a first and second racks. A first gear bushing is rotatably connected to the fixed base, and a rotatable second gear bushing is fitted onto the first gear bushing. Detachable slide rail supports are located at the top of both the first and second gear bushings, with locking devices on both slide rail supports and bending components on both locking devices. While this patent solves the problem of bending the wood panels, the operation is cumbersome. Furthermore, the device lacks protective devices, and broken wood fragments during bending can easily injure workers. The device also requires connection to an operating device (computer), making it inconvenient.

[0004] To address the aforementioned technical problems, this application proposes a solution. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] The directional terms used in the detailed description paragraphs are only for the convenience of those skilled in the art to understand the technical solutions described in this application based on the visual orientation shown in the accompanying drawings. Unless otherwise expressly specified and limited, the terms "setting," "installation," "connection," etc., should be interpreted broadly, and those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] like Figures 1 to 6 As shown, a device for testing the bending resistance of wood panels used in furniture processing includes a moving mechanism 2, a bending mechanism 1 fixedly connected to the moving mechanism 2, and an operating mechanism 3 slidably connected to one side of the moving mechanism 2. The moving mechanism 2 includes a base plate 202, with columns 204 fixedly connected around the upper perimeter of the base plate 202. An energy storage device 203 is fixedly connected to the upper part of the base plate 202. The energy storage device 203 mainly provides a mobile power source for the operation display panel 308, allowing for testing in locations where power is inconvenient. Under normal circumstances, the device can draw power from an external source and power the entire device through the energy storage device 203. A limiting plate 206 is fixedly connected to one side of the base plate 202 of the energy storage device 203. A lead screw 207 is bolted to the limiting plate 206. A rotating ring 205 is fixedly connected to one end of the lead screw 207 near the energy storage device 203, and the operating mechanism 3 is rotatably connected to the other end of the lead screw 207. By rotating the rotating ring 205, the lead screw 207 is rotated, thereby extending and retracting the operating mechanism 3. One end of the column 204 is fixedly connected to the top plate 208 and the semi-circular plate 209. The semi-circular plate 209 has a semi-circular groove 2091. A rotating column 210 is fixedly connected to the center of the semi-circular plate 209. A pressure sensor 211 is fixedly connected to one side of the rotating column 210. The function of the pressure sensor 211 is to detect the pressure parameters of the plate when it is bent.

[0024] like Figure 4As shown, the operating mechanism 3 includes an outer box 302, which is hollow inside and has a slot on the side near the moving mechanism 2. Two sliding rods 301 are fixedly connected to the bottom of the outer box 302 near the moving mechanism 2. The sliding rods 301 are slidably connected to the base plate 202. The extension and retraction of the outer box 302 are realized by the extension and retraction of the lead screw 207. The sliding rods 301 slide inside the base plate 202 and can also provide support for the operating mechanism 3. A fixing plate 303 is fixedly connected to the bottom of the outer box 302 near the moving mechanism 2. A hydraulic telescopic device 304 is fixedly connected to the fixing plate 303. An inner box 307 is slidably connected inside the outer box 302. A fixing plate 306 is fixedly connected to the inner box 307 near the moving mechanism 2. The protruding end of the hydraulic telescopic device 304 is fixedly connected to the fixing plate 306. C-shaped plates 305 are fixedly connected to both sides of the slot in the outer box 302. One side of the C-shaped plate 305 is rotatably connected to the lead screw 207. An operation display panel 308 is rotatably connected to the inner box 307 away from the moving mechanism 2. The operation display panel 308 is made by encapsulating the display and keyboard together. The display can be an all-in-one computer, or the main unit can be placed in the energy storage device 203. The bending resistance test of the board is performed by operating the keyboard and viewing the display. The inner box 307 is made of transparent acrylic. This has the advantage that when a person stands at the control display panel 308, the transparent inner box 307 allows for easy observation of the material bending, enabling them to make judgments based on the readings on the monitor. Furthermore, the inner box 307 also protects the worker from injury should the material break.

[0025] like Figure 5 As shown, the bending mechanism 1 includes a hydraulic telescopic device 101 fixed on the top plate 208. Two connecting plates 102 are rotatably connected to the extended end of the hydraulic telescopic device 101. Two bending plates 104 are rotatably connected to one end of each connecting plate 102. The two bending plates 104 are rotatably connected and rotatably connected to a rotating column 210. A guide column 103 is provided at the bottom of the connection between the connecting plate 102 and the bending plate 104, and is fixedly connected to the bending plate 104. The guide column 103 is slidably connected to a semi-circular groove 2091. A slot is formed in the middle of the bending plate 104, and a clamping device 105 is slidably connected within the slot. The guide column 103 slides in the semi-circular groove 2091, which better controls the bending plate 104 to prevent displacement.

[0026] like Figure 6As shown, the clamping device 105 includes an L-shaped plate 1053. A groove 1055 is formed on the upper part of the short side of the L-shaped plate 1053. A guide rod 1056 is slidably connected inside the groove 1055. The guide rod 1056 is the same length as the long side of the L-shaped plate 1053. One end of the guide rod 1056 passes through the L-shaped plate and is threadedly connected to a bolt 1054. A long column 1051 is fixedly connected to one side of the long side of the L-shaped plate 1053. A bolt 1052 is threadedly connected to both the long column 1051 and the L-shaped plate 1053 on one side. The long column 1051 and the L-shaped plate 1053 abut against the two sides of the groove in the bending plate 104. Placing the plate between the guide rod 1056 and the L-shaped plate 1053 and fixing the plate in place prevents the plate from moving during the bending test, thus avoiding inaccurate test readings. The bottom of the base plate 202 is fixedly connected to four casters 201, which can move the present invention at will.

[0027] Those skilled in the art can use existing technologies they possess, such as installing appropriate mechanical limit switches or photoelectric sensors, to limit the specified positions of each actuator during the following operation process; to achieve automated operation, this utility model can use numerical control technology or PLC to control the actions of each actuator.

[0028] Working Process: Determine the thickness of the sheet material to be tested. Move the device to the testing position using the bottom casters 201 and lock them. Extend the hydraulic rod of the hydraulic telescopic device 101 outwards, pushing the connecting plate 102, which in turn pushes the two bending plates 104, keeping them in a straight line. Move the clamping device 105 according to the length of the sheet material, positioning it on the bending plates 104. Secure the clamping device 105 to the bending plates 104 using the first fastening bolt 1052. After placing the sheet material on the clamping device 105, adjust the guide rod 1056 so that it is close to the sheet material, then tighten the second fastening bolt 1054 to secure the guide rod 1056.

[0029] Rotate the rotating ring 205 to make the lead screw 207 rotate, push out the operating mechanism 3, start the hydraulic telescopic device 2 304, the hydraulic rod of the hydraulic telescopic device 2 304 lifts the inner box 307, lifts the inner box 307 above the height of the plate, and removes the operation display panel 308 inside the inner box 307 from the inner box 307.

[0030] Activate hydraulic telescopic device 101; the hydraulic rod retracts, pulling the connecting plate 102 and causing the bending plate 104 to move backward. The two bending plates 104 bend backward, bending the sheet material. The middle of the sheet material is close to the pressure sensor 211. During bending, the bending point of the sheet material presses against the pressure sensor 211. The pressure reading obtained from the pressure sensor 211 is displayed on the operation display panel 308. This measures the sheet material's bending resistance.

[0031] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
