s60: and placing an embedded die 60 on the upper release paper, wherein the position of the embedded die 60 corresponds to the hole position on the perforated material sheet 30, and starting a forming press to form a protective shell.
Compared with the prior art, the forming method of the protecting shell for the observation window has the advantages that the material sheets are divided into the large material sheet 10, the small material sheet 20 and the perforated material sheet 30, the area corresponding to the observation window can be cut off on the perforated material sheet 30 in advance, the thickness of the area corresponding to the observation window and the handle part can be directly ensured to be smaller than that of other areas after compression forming, the subsequent processing requirements are met, the secondary thinning processing is not required to be carried out on the area corresponding to the observation window and the handle part, the production efficiency is improved, the production cost is reduced, and the integral quality of the protecting shell can be ensured; by adding the embedded die 60 into the forming press, the embedded die 60 can be correspondingly provided with holes on the material sheet 30, so that the forming pressure of a part area with smaller thinness is met, the strength of the material sheet with thinner thickness after being pressed is ensured, and the requirements of different thickness differences of the protective shell are met; release paper is paved at the top and the bottom of the preformed shell in the production process, so that demolding is facilitated, the protective shell and the embedded mould 60 are also facilitated to be separated, and as the shape of the embedded mould 60 is the same as that of the observation window, the outline of the embedded mould 60 can be printed on the protective shell after molding and pressing, and subsequent cutting operation is facilitated.
In some embodiments, a modified embodiment of the method for forming the protective casing for the observation window may be as follows. Also included before S10 is:
measuring a die gap d1 of the molding press;
calculating the total number n of webs according to the formula:
n=d1/ρ
wherein ρ is the density of the web;
calculating a thickness difference d2 of the protective shell corresponding to the mold gap d1 and the observation window;
the number n1 of small tablets 20 is calculated according to the formula:
n1=d2/ρ
wherein ρ is the density of the web;
the number of large webs 10 and apertured webs 30 is (n-n 1)/2, respectively.
1kg of the tablet has a theoretical thickness of 1mm at standard atmospheric pressure, i.e. the density can be regarded as 1; the mold gap of the molding press is equal to the thickness of the thicker part of the protective shell, so the mold gap can be regarded as the density of the protective shell, and the mold gap is divided by the density of the single material sheets, thereby obtaining the number of the material sheets required for the whole. For example, the thickness of the thicker portion of the protective shell is 20mm, the thickness of the thinner portion is 15mm, the large sheet 10 covers the thinner portion and the thicker portion, the small sheet 20 covers only the thicker portion, and the perforated sheet 30 lacks only the thinner portion, so that:
sum of all large web 10 thickness + sum of all small web 20 thickness + sum of all apertured web 30 thickness = 20mm;
sum of all large web 10 thickness + sum of all apertured web 30 thickness = 15mm;
the 5mm difference thus calculates the number of layers of the small material sheets 20, by which the required number of each material sheet and thus the quick laying can be calculated.
In some embodiments, a specific implementation of the insert mold 60 may have the following structure. The thickness of the insert mold 60 is d2. The thickness of the insert mold 60 is the same as the thickness difference between two areas with different thicknesses on the protective shell, so that the pressure values acting on the two areas with different thicknesses are equal in the pressing process of the same molding press, and the hardness and the quality of the two areas with different thicknesses after molding can be ensured to be the same.
In some embodiments, a specific implementation of the insert mold 60 may have the following structure. The insert mold 60 is a high strength aluminum plate and has the same shape as the openings in the protective housing. The embedded mould 60 adopts a high-strength aluminum plate, so that deformation can be reduced in the high-pressure working process of the forming press, the pressure of the embedded mould 60 acting on the protective shell is ensured to be constant, and the quality of a finished product of the protective shell is improved.
In some embodiments, a specific shape calculation method of the above-mentioned web may use the structure shown in fig. 3. Referring to fig. 3, the protective shell includes a first portion and a second portion, the thickness of the first portion is greater than that of the second portion, and the junction between the first portion and the second portion forms a junction contour, and the step S10 further includes:
placing the simulated material sheet into a spreading press for pre-pressing, and calculating the shrinkage of the simulated material sheet;
the shape of the large material sheet 10 is the shape of the inner cavity of the spreading press plus the shrinkage;
the large web 10 is cut along the boundary profile to form a small web 20 corresponding to the region of the first portion;
the large material sheet 10 is cut along the outer contour of the second portion to form an apertured material sheet 30.
By pressing the simulated material sheets in advance, the shrinkage of the material sheets can be obtained, and then the shapes of the material sheets can be directly obtained according to the shrinkage of the material sheets and the shape of the inner cavity of the spreading press, so that the shapes of various material sheets can be rapidly determined, and excessive cutting material sheets can be avoided, and the cost is increased.
In some embodiments, a modified embodiment of the above-described web may employ the structure shown in fig. 1 to 3. Referring to fig. 1 to 3, the outer edge of the web is recessed to form a first positioning portion 40. The first positioning portion 40 may be a semicircular notch, and the tablet may correspond to the guide post on the spreader after being placed in the spreader, and be clamped on the periphery of the guide post, so that the tablet can be prevented from laterally moving during the working process of the spreader, and the quality of the preformed shell is ensured.
In some embodiments, one embodiment of the large web 10 and the apertured web 30 may take the configuration shown in fig. 1 and 3. Referring to fig. 1 and 3, first positioning portions 40 are provided on opposite sides of the large web 10 and the apertured web 30, respectively. For example, the large web 10 has two first positioning portions 40 on a first side and two first positioning portions 40 on a second side, the second side being the opposite side of the first side; the apertured web 30 is the same. The outer contours of the large material sheet 10 and the perforated material sheet 30 are the same, and the positioning effect can be improved and the material sheet can be prevented from moving by arranging the first positioning parts 40 on the two opposite sides.
In some embodiments, a modified embodiment of the apertured web 30 described above may employ the structure shown in FIG. 3. Referring to fig. 3, the hole side walls of the hole-punched web 30 are projected to form the second positioning portions 50. Correspondingly, the male die of the spreading press is also provided with a corresponding recess, the side wall of the hole of the perforated material sheet 30 can correspond to the recess on the male die, and further, the profile deformation of the hole in the spreading process can be avoided, and the uneven thickness after pressing due to the skew hole profile in the place with a thinner thickness is avoided.
In some embodiments, one specific operation of the molding press described above may be as follows. The pressing process of the molding press comprises the following steps:
heating to a preset temperature after the molding press is closed;
pressurizing to a preset value after the forming press is exhausted for a plurality of times, and preserving heat and pressure for a preset duration;
and (5) cooling to room temperature for demolding after exhausting for a plurality of times, and taking down the embedded mold 60 and release paper on the protective shell.
For example: and (3) placing the preformed shell into a forming press, heating after die assembly, exhausting for 4 times after the temperature is increased to a preset temperature, pressurizing to the preset value after the exhaust is completed, transferring into a heat preservation and pressure maintaining system for 1 hour, exhausting again for 3 times, transferring into a cooling system, cooling to room temperature, demolding, and taking off release paper and the embedded mold 60 after demolding to obtain a protective shell finished product.
The heating system and the cooling system are systems of the forming press, a variable-temperature module is arranged in the die, and the temperature of the variable-temperature module is controlled by the controller, so that the heating, heat preservation and cooling processes are realized.
Optionally, the preset value is 250MPa. The temperature value is adopted during pressure maintaining, so that close adhesion between adjacent material sheets can be ensured, and the integral strength of the finally formed protective shell is improved.
The foregoing description of the preferred embodiments of the application is not intended to be limiting, but rather is intended to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the application.
