Description

Technical Field

[0001] The invention relates to the technical field of heat bending machines, and in particular to a heating plate adjusting jig for heat bending machines. Background Art

[0002] In the 3D glass production process, the flat glass is placed in the upper and lower concave and convex molds of graphite, and the graphite mold loaded with the flat glass is placed in a heat bending machine. There is a heating plate with a heating rod inserted in the heat bending machine. The graphite mold is first placed between the upper heating plate and the lower heating plate for heating. The flat glass softens after being heated, and then the upper heating plate is pressed down to form the flat glass in the graphite mold by heat pressing. Therefore, the relative levelness, flatness, and deformation of the upper and lower heating plates have a crucial influence on the forming of 3D glass. In practical applications, due to the frequent pressure of the upper heating plate on the graphite mold, it is easy to deform or tilt at the installation position on the machine. In the prior art, there is a lack of molds for comprehensively detecting the surface shapes of the upper and lower heating plates. Generally, the surface conditions of the upper and lower heating plates are judged by the 3D glass products pressed out by heat, which not only has a long cycle and is difficult to detect comprehensively and accurately, but also has great economic losses. Summary of the invention

[0003] In order to solve the technical problems existing in the background technology, the present invention provides a heating plate adjustment jig for a hot bending machine.

[0004] A hot bending machine heating plate adjustment jig comprises: a jig body and a shaping material. The bottom surface of the jig body is a horizontal plane. The inside of the jig body has a hole body in which an upper heating plate and a lower heating plate can be mounted. When the first type of test is performed, the bottom surface of the jig body is pressed onto a machine table that fits the bottom surface of the lower heating plate. The bottom surface of the upper heating plate and the top surface of the lower heating plate in the hole body need to be filled with the shaping material. When the upper heating plate presses down on the shaping material between the bottom surface of the upper heating plate and the top surface of the lower heating plate, the surface shapes of the bottom surface of the upper heating plate and the top surface of the lower heating plate will be respectively imprinted onto the upper surface and the lower surface of the shaping material.

[0005] Preferably, the fixture body is a split structure that can be disassembled in the horizontal direction.

[0006] Preferably, the projection boundary of the hole space in the horizontal direction should slightly exceed the projection boundaries of the upper heating plate and the lower heating plate in the horizontal direction.

[0007] Preferably, the shaping material is provided with a first mark for distinguishing the upper surface and the lower surface thereof.

[0008] Preferably, a second mark is provided on the upper surface or the lower surface of the shaping material to assist in identifying its position corresponding to the bottom surface of the upper heating plate or the top surface of the lower heating plate.

[0009] Preferably, blocks of equal height are provided at the four corners of the peripheral wall of the hole body, and the upper and lower surfaces of the blocks are parallel horizontal planes. When conducting the second type of test, the lower surface of the block needs to be against the top surface of the lower heating plate, and test paper is placed on the upper surface of the block. When the upper heating plate is pressed down to generate a certain pressure between it and the upper surface of the block, the test paper will leave marks due to the pressure.

[0010] Preferably, the test paper is pressure-sensitive paper, which will show color changes of different shades when subjected to different pressures.

[0011] Compared with the prior art, the beneficial effects of the hot bending machine heating plate adjustment fixture proposed by the present invention are:

[0012] By using a shaping material in the fixture body, the model data of the bottom surface of the upper heating plate and the top surface of the lower heating plate can be fully and accurately collected, providing an accurate reference for subsequent adjustment and repair of the upper heating plate and the lower heating plate.

[0013] By setting a block on the fixture body and using pressure-sensitive paper, the relative levelness between the upper heating plate and the lower heating plate, the flatness of the upper heating plate and other external conditions can be preliminarily, quickly and intuitively determined.

[0021] The specific implementation of the present invention will be described in detail below with reference to the accompanying drawings.

[0022] Reference Figures 1 to 3 , which is the first embodiment of the present invention, a hot bending machine heating plate adjustment jig includes: a jig body 1, a shaping material 4, the bottom surface of the jig body 1 is a horizontal surface, and the jig body 1 has a rectangular hole body 1a inside which the upper heating plate 2 and the lower heating plate 3 can be set. When the first type of test is performed, the bottom surface of the jig body 1 is pressed on the machine table that fits the bottom surface of the lower heating plate 3, and the space between the bottom surface of the upper heating plate 2 and the top surface of the lower heating plate 3 in the hole body 1a needs to be filled with the shaping material 4. When the upper heating plate 2 presses down the shaping material 4 between the bottom surface of the upper heating plate 2 and the top surface of the lower heating plate 3, the bottom surface of the upper heating plate 2 and the top surface of the lower heating plate 3 are The surface shape will be imprinted onto the upper and lower surfaces of the shaping material 4 respectively. In actual applications, the shaping material 4 can be made of plaster, plasticine and other materials. Subsequently, the coordinate values ​​of each point on the upper and lower surfaces of the shaping material 4 can be measured by measuring instruments such as a three-dimensional scanner, and after taking the opposite value of the height values ​​of these coordinate values, an accurate model of the bottom surface of the upper heating plate 2 and the top surface of the lower heating plate 3 can be created. According to the created model, the relative horizontality, flatness, surface protrusions and depressions and other appearance of the bottom surface of the upper heating plate 2 and the top surface of the lower heating plate 3 can be judged, providing an accurate reference for the subsequent adjustment and repair of the upper heating plate 2 and the lower heating plate 3.

[0023] In order to facilitate the removal of the qualitative materials that have been embossed on the upper and lower surfaces from the jig body 1, the jig body 1 is a split structure that can be disassembled in the horizontal direction. In practical applications, the jig body 1 can be made into a left-right splicing type, and the jig body 1 can be divided into two parts 11 and 12, which are connected by bolts at the splicing point 13.

[0024] In order to prevent the upper heating plate 2 and the lower heating plate 3 from being not installed in a horizontal state on the machine or from being bent and deformed due to their own lack of flatness, the horizontal projection boundary of the hole body 1a space should slightly exceed the horizontal projection boundary of the upper heating plate 2 and the lower heating plate 3 to ensure that the hole body 1a can accommodate the upper heating plate 2 and the lower heating plate 3 therein.

[0025] In order to facilitate the distinction between the corresponding surfaces of the shaping material 4 and the bottom surface of the upper heating plate 2 and the top surface of the lower heating plate 3 after the shaping material 4 is taken out from the jig body 1, a first mark that can distinguish the upper surface 41 and the lower surface 42 is provided on the shaping material 4. In practical applications, different colors of shaping materials 4 can be used on the bottom surface of the upper heating plate 2 and the top surface of the lower heating plate 3 to achieve distinction.

[0026] Furthermore, a second mark is provided on the upper surface 41 or the lower surface 42 of the shaping material 4 to assist in identifying its corresponding position with the bottom surface of the upper heating plate 2 or the top surface of the lower heating plate 3. In practical applications, shaping materials of different colors can be used at each boundary of the upper surface 41 or the lower surface 42 of the shaping material 4 to achieve distinction.

[0027] Reference Figure 4 To Figure Figure 7 , which is the second embodiment of the present invention, blocks 1b of equal height are also arranged at the four corners of the peripheral wall of the hole body 1a, and the upper surface and lower surface of the block 1b are parallel horizontal planes. When the second type of test is performed, the lower surface of the block 1b needs to be attached to the top surface of the lower heating plate 3, and a test paper is placed on the upper surface of the block 1b. When the upper heating plate 2 is pressed down to generate a certain pressure between it and the upper surface of the block 1b, the test paper will leave marks due to the pressure.

[0028] In practical applications, the second type of test can be performed on the upper heating plate 2 and the lower heating plate 3 first, and the relative levelness of the upper heating plate 2 and the lower heating plate 3 can be judged from the marks pressed out by the test paper, and the installation position of the upper heating plate 2 can be adjusted accordingly on the machine. Then, the second type of test can be performed again to obtain model data in which the complete bottom surface of the upper heating plate 2 is imprinted on the upper surface 41 of the shaping material, and most of the top surface of the lower heating plate 3 is imprinted on the lower surface 42 of the shaping material.

[0029] In order to facilitate the observation of the pressure marks on the test paper, the test paper is pressure-sensitive paper. The pressure-sensitive paper is filled with microcapsules containing chromogenic substances. When subjected to pressure, the microcapsules rupture, the chromogenic substances and the color-developing substances react with each other, and a red area appears on the pressure-sensitive paper. By observing the color changes on the pressure-sensitive paper, the distribution of pressure can be intuitively understood.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
