Detailed Description
The core of the invention is to provide a shaping clamp and a shaping method for a ceramic plate, so as to solve the problems that the energy consumption is large, the time consumption is long and the reliability of the shaped product is influenced during the shaping of a cover plate.
In order to make those skilled in the art better understand the technical solutions provided by the present invention, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 8, an embodiment of the present invention provides a shaping jig for ceramic plates, including a base 1, a cover plate 2 fixed on the base 1, and a pressing device 3 disposed on the cover plate 2; a positioning part 5 for positioning the product 4 to be shaped is arranged between the base 1 and the cover plate 2; and the pressing device 3 is used for pressing the pressing area of the product 4 to be shaped to a preset position.
Above-mentioned integer anchor clamps, in the in-service use process, treat the integer product through the location portion between base and the apron and fix a position, then treat the pushing down region that the integer product corresponds through the pushing down device that sets up on the apron and push down to preset the position, will treat that the integer product is whole to be put into constant temperature roaster with the integer anchor clamps at last and toast and can make the product resume to required appearance characteristic, because the physical effect of exerting pressure that the integer product was treated to integer anchor clamps itself makes the pushing down region of treating the integer product can take place physical deformation, and the purpose of toasting mainly lies in the design and does not lie in making the product take place deformation, therefore toasting temperature in the roaster compares in traditional high temperature reviving technology (the pottery class product generally needs about 1000 ℃ high temperature to go on for a long time about 20h), can greatly reduced toasting temperature (the toasting temperature of the pottery class product after adopting the integer anchor clamps to reshape can realize about 200 ℃) and toasting duration (adopt the integer The baking time of the ceramic product shaped by the mould clamp is generally within 2 h); in addition, due to the deformation process of the shaping clamp, the baking and shaping temperature is not too high generally, so that the phenomenon of interaction between the product and powder in the baking oven is not easy to occur, the generation of convex points is further avoided, and the problem that the reliability of the product is influenced is also avoided.
In some specific embodiments, the specific structure of the pressing device may include a pressing rod vertically penetrating through the cover plate 2 in a slidable and self-locking manner, and the pressing rod penetrates through one end of the cover plate 2 for abutting against the product to be shaped. For example, the pressure lever can be embodied as a thrust lever, the cover plate 2 is provided with a threaded hole 21, the thrust lever is in threaded fit with the threaded hole 21, the threads on the thrust lever are screwed into the threaded hole by the depth driven by a manual adjustment or driving mechanism, and the pressing amount of the thrust lever can be adjusted; for example, the pressure lever is a piston rod of a piston cylinder, the piston cylinder is fixed on the cover plate 2, and the cover plate 2 is provided with a through hole for the piston rod of the piston cylinder to pass through. The pressing area of the product to be shaped is pressed by the piston rod penetrating through the through hole, and the pressing amount can be adjusted by driving the deep length of the piston rod through the driving mechanism.
It should be noted that, the structure of the thrust rod and the structure of the piston cylinder are merely preferred examples of the specific structure of the pressing rod according to the embodiment of the present invention, and in the practical application process, other pressing rod structures commonly used by those skilled in the art may also be selected according to requirements, for example, the pressing rod is a pushing rod of a linear stepping motor fixed on the cover plate, and the pushing amount can be accurately controlled by controlling the pushing amount of the pushing rod of the linear stepping motor. In addition, generally speaking, the pressing amount of most ceramic cover plates is 3-6mm, it is understood that the embodiment of the invention is only a preferred example of the pressing amount of a certain conventional product, and in the practical application process, the corresponding pressing amount can be selected according to different types of products.
In a further embodiment, in order to ensure that the pressed area of the pressing rod is more uniformly stressed when the pressing rod presses down the pressed area of the product to be shaped, a first base plate 6 is arranged at one end of the pressing rod penetrating through the cover plate 2, and the area of the first base plate 6 is larger than that of the end part of the thrust rod. The area of exerting pressure can be increased through setting up first backing plate, avoids the emergence of the cracked condition of ceramic plate that local atress is inhomogeneous to result in.
It should be noted here that, in general, the first pad 6 is preferably a circular plate, and the diameter of the circular plate is smaller than the width of the product 4 to be shaped. Because the pressing area of the product to be shaped is generally circular, the first base plate is designed into a circular plate to apply force to the pressing area more uniformly; in addition, the diameter of the circular plate is designed to be smaller than the width of a product to be shaped, so that when the first base plate presses down the ceramic plate with the curved edge, the first base plate can reasonably avoid the curved surface structure of the edge, the curved surface structure of the edge is prevented from being damaged, for example, the curved surface structure of the 2.5D ceramic rear cover is prevented from being damaged, the middle part of the first base plate is of a plane structure, the peripheral edge of the first base plate is of an arc structure processed through an arc, the first base plate is slightly smaller than the width of the product to be shaped at the moment, and the arc structure can be avoided from being damaged in the pressing. It is understood that the circular plate is merely a preferred example of the structural shape of the first pad according to the embodiment of the present invention, and other types of structural shapes can be designed according to the shape of the pressing region in practical applications.
In a further embodiment, in order to further ensure the uniformity of the pressure applied by the first pad 6 on the pressing area, avoid the local over-high stress, and simultaneously avoid the first pad scratching the pressing area of the product to be shaped, the first pad 6 is provided with a first high temperature resistant flexible layer at least on the end surface matched with the pressing area. The first high temperature resistant flexible layer is generally selected as a high temperature resistant adhesive tape layer, but in practical application, the first high temperature resistant flexible layer may also be other high temperature resistant flexible material layers commonly used by those skilled in the art, such as a rubber layer. It should be noted that the material of the first backing plate is generally an aluminum plate, and of course, in practical applications, the first backing plate made of other materials may be selected according to practical requirements.
In order to better determine the specific position of the preset position, a position corresponding to the pressing area on the base 1 is provided with a limiting reference block 7, and when the pressing device 3 presses the product 4 to be shaped to the preset position, the limiting reference block 7 is attached to the product 4 to be shaped above the limiting reference block 7. Through setting up spacing reference block 7 for the push down device will treat the integer product and push down to preset position after, can't continue to push down the operation, the operator can know to push down and put in place this moment, has avoided the problem that there is the deviation in artifical manual control volume of pushing down. And the thickness of the corresponding limit reference block can be obtained according to the yield of the shaped corresponding product.
In order to improve the working efficiency of the shaping jig, the positioning portion 5 includes a plurality of layers of sub-positioning portions 51 disposed between the base 1 and the cover plate 2, and each layer of sub-positioning portions 51 can position one product 4 to be shaped. Here, the plurality of layers of the sub-positioning portions 51 may be arranged in one layer or in a plurality of layers.
When the sub-positioning portion 51 has only one layer, the sub-positioning portion 51 and the base 1 may be integrated or separated; and is preferably an integrally formed structure when the sub-positioning portion and the base are of an integrally formed structure.
When the sub-positioning portion 51 has multiple layers, the sub-positioning portion 51 located at the bottommost layer may be an integral structure or a split structure with the base 1, and when the sub-positioning portion and the base are an integral structure, an integral structure is preferred; in addition, be split type structure between the sub-location portion 51 of other layers except that the bottommost layer and between sub-location portion 51 and the base 1, it is all very convenient when making each layer of sub-location portion installation treat the integer product like this, can treat the integer product from the successive layer installation from bottom to top to arbitrary adjacent two treat all be provided with second backing plate 10 between the integer product 4, second backing plate 10 and the product of treating the integer of its both sides are to the laminating. That is, the second cushion plate is arranged at the position corresponding to the pressing area in the gap between any two adjacent products to be shaped, and the thickness of the second cushion plate is matched with the size of the gap. Generally, the thickness of the second pad is equal to or slightly larger than the gap size before the two products to be shaped are pressed down, and the value is preferably larger than the gap size by 1 mm. The pressure applying force of the multi-layer product to be reshaped from top to bottom is synchronously transmitted through the second base plate, so that the reshaping fixture can press down a plurality of products to be reshaped at one time, and the working efficiency of the reshaping fixture is greatly improved.
In a more specific embodiment, the specific structure of the sub-positioning portion 51 may include a first partition plate 511 and a second partition plate 512, and the first partition plate 511 and the second partition plate 512 are respectively used for supporting two ends of the product 4 to be shaped of the corresponding layer. It should be noted that the structural forms of the first partition plate and the second partition plate are mainly set for the plate product to have a rectangular shape, and are merely preferred examples of the sub-positioning structural form of the embodiment of the present invention, and in the practical application process, the plate product may be designed into other corresponding positioning structural forms according to the specific shape structure of the product to be shaped, as long as the function of supporting and positioning the product to be shaped can be achieved.
In a further embodiment, the first partition 511 and the second partition 512 are each provided with a supporting groove 8 adapted to the corresponding end of the product to be shaped 4 of the corresponding layer. It should be noted that, the supporting groove adapted to the supporting groove means that the depth of the supporting groove should be slightly greater than the thickness of the corresponding end of the product to be shaped, so that the first partition plate and the second partition plate only have the supporting function on the two ends of the product to be shaped, and do not generate the clamping force, thereby avoiding the problem that the two ends of the product to be shaped are easily broken due to the pulling force in the process of pressing down the product to be shaped.
In addition, in order to enable the product to be shaped, the support groove 8 is prevented from influencing the bending deformation of the corresponding two end positions of the product to be shaped in the pressing process, the bottom groove surface of the support groove 8 is designed into an inclined surface 9 which can form an avoidance space for the pressing deformation of the product to be shaped 4, and the required size can be enabled to be closer to the product after the product is shaped. Furthermore, a chamfer is typically provided at the outer end edge of the inclined surface 9. The problem that the edge arc-shaped area of the product to be shaped and the edge position of the supporting groove are concentrated in stress to enable the product to be shaped to be cracked can be avoided by arranging the chamfer.
In some more specific embodiments, the angle of inclination of the inclined surface 9 is preferably generally 2 ° to 15 °. In general, the specific value can be determined according to the pressing amount required for the to-be-shaped region of the to-be-shaped product and the dimensional relationship of the whole to-be-shaped product (i.e., the ceramic plate). Repeated tests on the relationship between the size and the pressing amount of the rear cover of the ceramic mobile phone with various common specifications show that generally, the inclination angle of the inclined plane falls within the range of 2-15 degrees. It is understood that the above is only a preferred example of the inclination angle of the inclined plane according to the embodiment of the present invention, and in practical applications, other corresponding inclination angles may be selected according to the material, the size and the structure of the product to be shaped and the required relief space corresponding to the pressing amount.
In addition, it should be noted that, in general, the product to be shaped includes the following two types, one type is that the product to be shaped is a flat plate type ceramic plate, at this time, the second backing plate only needs to be completely attached to the pressing area, and there is no limitation on whether the width direction of the product to be shaped exceeds the product to be shaped, and the transmission effect of the force when pressing down is not affected; when the product 4 to be shaped is a ceramic plate with a curved edge (such as a 2.5D back cover of a mobile phone), in order to avoid the edge position by the second pad, the second pad 10 is not only required to be arranged right opposite to the pressing area, but also required to be ensured to be located inside the edge of the plate.
In order to better explain the selection of the size of the second cushion plate, the sizes of the second cushion plate in two directions are named in a self-defining way, the second cushion plate 10 comprises a first size and a second size, the first size is the size of the second cushion plate 10 in the length direction of the product 4 to be shaped, and the second size is the size of the second cushion plate 10 in the width direction of the product 4 to be shaped; for most ceramic 2.5D cell phone back covers, the first dimension is 1/4-1/3 of the length dimension of the product to be shaped, and the second dimension is 5-10mm smaller than the width dimension of the product to be shaped. The size of the second cushion plate is verified for many times, if the size of the second cushion plate exceeds the range, the transmission effect of the pressing device on the force is poor, the thrust is not concentrated, a good shaping effect cannot be achieved, the yield is low, and if the size of the second cushion plate is smaller than the range, the second cushion plate is prone to position deviation from the preset central area of the product under the thrust action of the pressing device, and the final shaping effect can also be influenced. It is understood that the above-mentioned limitations on the two-directional dimensions of the second mat 10 are only preferred designs of the present invention for certain specific types of ceramic cover plate products, and during practical applications, other corresponding limitations may be selected according to different types of products and different shaping requirements, as long as the edge structure of the plate member is not affected.
It should also be noted that for most ceramic slab products, the hold-down region is generally located in the middle of the product to be shaped.
In order to avoid scratching the product to be shaped by the second base plate 10 and to ensure the uniformity of the force application surface when the second base plate transmits pressure, the second base plate 10 is provided with a second high-temperature-resistant flexible layer at least on the surface attached to the product to be shaped. Of course, the second backing plate may be covered with the second high temperature resistant flexible layer. And the second high temperature resistant flexible layer is preferably a high temperature resistant adhesive tape layer. It should be noted that the above-mentioned high temperature resistant adhesive tape layer is only a preferable example of the second high temperature resistant flexible layer according to the embodiment of the present invention, and other high temperature resistant flexible layers commonly used by those skilled in the art, such as a high temperature resistant rubber layer, may also be used in the practical application process. It should be noted that the second backing plate is also preferably made of an aluminum plate material, but of course, the aluminum plate material is merely a preferable example of the present invention, and other materials may be selected correspondingly.
In some more specific embodiments, the base 1, the sub-positioning portion 51 and the cover 2 can be fixed together by a fastener, such as a nut through the screw 11. It is understood that the above-mentioned fixing manner is only a preferred fixing manner of the embodiment of the present invention, and in the practical application process, other fixing manners commonly used by those skilled in the art may also be selected according to practical requirements, for example, a limiting groove for limiting the sub-positioning portion and the cover plate is provided on the base, and an arrangement manner that the sub-positioning portion and the cover plate are all clamped in the limiting groove is provided on the base.
In addition, the invention also provides a shaping method of the ceramic plate, which adopts the shaping clamp of the plate described in any scheme to carry out shaping and comprises the following steps:
step S1: positioning a product 4 to be shaped on a positioning part 5 of the shaping clamp;
step S2: pressing down the pressing area of the product to be shaped to a preset position through a pressing-down device 3 of the shaping clamp;
step S3: integrally placing the product 4 to be shaped after the pressing operation and the shaping clamp in a preset high-temperature environment and preserving heat for a preset time;
step S4: taking out the product 4 to be shaped after the heat preservation operation and the shaping fixture are integrally finished, and then naturally cooling;
step S5: and after the product 4 to be shaped and the shaping fixture are integrally cooled naturally, the product 4 to be shaped is detached from the shaping fixture, and a finished product after shaping can be obtained.
Because the shaping method of the plate adopts the shaping clamp of the plate for shaping, the core idea of the shaping clamp is also included, and the shaping clamp has the technical effect, the shaping method also has the corresponding technical effect, and the details are not repeated herein.
In some specific embodiments, the preset high temperature environment in the step S3 is 180 ℃ to 250 ℃ and the preset time is 1h to 2 h; the natural cooling time in the step S4 is generally 20-40min, preferably 30 min; the flatness of the finished product after shaping in the step S5 can reach 0.1-0.3 mm. It should be noted that the above temperature and time parameters are only preferred examples of the temperature and time parameters for shaping the ceramic cover plate product with certain specifications according to the embodiments of the present invention, and in practical applications, other temperature and time parameters may be selected according to the size and type of the product to be shaped.
The shaping jig and the shaping method for ceramic plates according to the present invention are described in detail above. It should be noted that, in the present specification, the embodiments are all described in a progressive manner, each embodiment focuses on differences from other embodiments, and the same and similar parts among the embodiments may be referred to each other.
