DETAILED DESCRIPTION

[0021] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the utility model, so as to fully understand the purpose, characteristics and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model.

[0022] Reference Figure 1-3 The embodiment of the utility model provides a composite plate shaping device, including a mounting frame 1, a support plate 2, a support block assembly, a pressing plate 4 and a driving cylinder 5. Specifically, the driving cylinder 5 and the support plate 2 are respectively arranged at the upper and lower parts of the mounting frame 1, the output shaft of the driving cylinder 5 extends or retracts downward, and the end of the output shaft is fixedly connected to the upper part of the pressing plate 4, a plurality of pressing rods 41 are evenly arranged in the middle part of the lower surface of the pressing plate 4, and a support block assembly is fixedly arranged on the upper surface of the support plate 2 for supporting the four sides of the composite plate 6.

[0023] There are five pressure rods, four of which are arranged in a matrix and one is arranged in the middle. The pressure rods are welded to the lower part of the pressure plate 4.

[0024] The length of the pressure rod 41 is 30mm-50mm, and the diameter is 5mm-8mm. If the pressure rod 41 is too long, it is easy to bend. If it is too short, the pressure plate 4 will be too close to the support block assembly, which is easy to bump. Setting a pressure rod 41 with a length of 30mm-50mm can have better bending performance and prevent the pressure plate 4 from bumping the support block assembly. Setting a length of 5mm-8mm can prevent the composite plate 6 from being pierced by excessive pressure due to a small effective area, and can also prevent the composite plate 6 from being unable to fit well after bending due to a large contact surface.

[0025] In this embodiment, a support block assembly is arranged on the support plate 2 to support the four side edges of the composite plate 6, and then the pressure plate 4 is driven downward by the driving cylinder 5, so that the pressure rod 41 in the middle of the pressure plate 4 can be driven to press down the middle of the composite plate 6. Under the interaction of the pressure rod 41 and the support block assembly, the four sides of the composite plate 6 can be bent upward at a certain angle. The hot pressing device for the composite plate 6 has the characteristics of simple structure and low production cost.

[0026] For details, please refer to Figures 1 to 3 The support block assembly includes four corner support blocks 31 and a plurality of side support blocks 32 fixedly arranged on the support plate 2. The four corner support blocks 31 are arranged in a rectangular array, and at least one side support block 32 is arranged between two corner support blocks 31. In this embodiment, the four corner support blocks 31 are arranged in a rectangular array to support the four corners of the composite plate 6 while avoiding the middle space, making it convenient for the pressure rod 41 to press down and shape the composite plate 6. The side support blocks 32 are arranged on the side to ensure the bending effect of the side. In other embodiments, a hollow support frame can be directly enclosed by multiple support blocks, which can also achieve the effect of support shaping.

[0027] Furthermore, the support block assembly also includes a limit block 33 disposed in the middle of the support plate 2, and the height of the limit block 33 is less than the height of the corner support block 31. In this embodiment, the support height of the corner support block 31 is flush with the support height of the side support block 32, so that the side panels of the composite plate 6 can be bent relatively flat, ensuring the overall bending effect. Setting the height of the limit block 33 lower than the height of the corner support block 31 can ensure that the pressing rod 41 is pressed down normally, and at the same time can effectively prevent the composite plate 6 from being damaged due to excessive pressing distance, effectively improving the product yield.

[0028] For further information, please refer to Figures 1 to 3 The corner support block 31 is provided with an L-shaped positioning portion 311, and the four L-shaped positioning portions 311 cooperate to position the composite board 6. Among them, the four corner support blocks 31 correspond to the four corners of the composite board 6, and the composite board 6 can be positioned by cooperating with the four L-shaped positioning portions 311, which can ensure the bending part of the composite board 6 and the shaping accuracy. Similarly, the side support block 32 is provided with a long strip positioning portion 321, which is used to position the side of the composite board 6 to ensure processing accuracy.

[0029] Among them, there is a clearance fit between the four L-shaped positioning parts 311 and the composite board 6, which is convenient for loading the composite board 6. At the same time, the interval between the corner support block 31 and the side support block 32 can form an avoidance position, which is convenient for picking up the finished composite board 6. Preferably, the upper part of the four L-shaped positioning parts 311 is provided with a chamfer to facilitate the alignment of the composite board 6 and improve the convenience of loading.

[0030] For further information, please refer to Figures 1 to 3 The support surface of the upper part of the corner support block 31 is inclined at a certain angle to the middle part of the support plate 2; the support surface of the upper part of the side support block 32 is inclined at a certain angle to the middle part of the support plate 2. By setting the support surfaces of the corner support block 31 and the side support block 32 to be inclined toward the lower side of the middle part, the contact area between the composite plate 6 and the corner support block 31 and the side support block 32 can be continuously increased during the downward pressure deformation process, thereby ensuring the stability of the shaping.

[0031] Furthermore, a first buffer rubber pad (not shown in the figure) is provided on the upper support surface of the corner support block 31; a second buffer rubber pad (not shown in the figure) is provided on the upper support surface of the side support block 32; and a rubber sleeve 42 is provided at the bottom of the pressure rod 41. By adding the first buffer rubber pad, the second buffer rubber pad and the rubber sleeve 42, it is possible to prevent the pressure rod 41, the corner support block 31, the side support block 32 and the composite board 6 from being worn during the hot pressing shaping process, thereby affecting the product yield.

[0032] For further information, please refer to Figures 1 to 3 A heating plate (not shown in the figure) is provided on the support plate 2. By adding the heating plate, the composite plate 6 can be heated and softened before pressing down for shaping, which is convenient for the subsequent shaping process. Preferably, the heating plate is an annular plate, the size of which corresponds to the outer edge of the composite plate 6, and the bending part can be accurately heated, thereby improving the heating efficiency.

[0033] Furthermore, the mounting frame 1 includes a bottom plate 11, a top plate 13 and four connecting rods 12, the four connecting rods 12 connect the bottom plate 11 and the top plate 13, the driving cylinder 5 is fixedly arranged on the top plate 13, and the support plate 2 is arranged on the bottom plate 11. Four sleeves (not shown in the figure) are respectively arranged on the four corners of the pressing plate 4, and the four sleeves are respectively slidably sleeved on the four connecting rods 12. By arranging the sleeves on the four corners of the pressing plate 4 and sliding up and down along the connecting rods 12, the stability of the pressing and shaping can be ensured.

[0034] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
