Description

Technical Field

[0001] The present invention relates to the technical field of workpiece hot pressing, and particularly to a hot press for producing corner plates. Background Art

[0002] In an assembled building, at the corner of a wall, adjacent wall panels are usually connected together by a corner plate, which can improve the sealing of the indoor space.

[0003] A right-angle corner plate is generally composed of inner and outer L-shaped color steel plates, an adhesive, and an intermediate rock wool layer. The right-angle corner plate is mainly used in purification rooms in hospitals, laboratories, and pharmaceutical factories. A purification room is generally composed of components such as wall panels, right-angle corner plates, door and window panels, roof plates, sealing materials, metal structural members, and vacuum glass.

[0004] However, due to the limitation of its own specific shape, the existing production operation of the corner plate includes: manually assembling the blank, manually pressing and pasting, clamping the assembled corner plate with a fixture, applying pressure with heavy steel, and finally completing the gluing of the finished product. Such operation has low production efficiency and high labor cost. At present, there is no supporting equipment in the market to automatically manufacture corner plates. Summary of the Invention

[0064] As Figures 1 to 5 shown, the present invention provides a hot press for producing corner plates. The above-mentioned corner plate 5 is composed of a first straight plate portion 51 and a second straight plate portion 52 that form an angle with each other. The above-mentioned hot press includes:

[0065] A frame 1;

[0066] An inner mold hot pressing mechanism 2. The inner mold hot pressing mechanism 2 includes a lifting drive mechanism 21 provided on the frame 1 and an inner pressure module 22 connected to the lifting drive mechanism 21. The inner pressure module 22 moves up and down in the vertical direction driven by the lifting drive mechanism 21. A first hot pressing plate 23 for pressing on the inner side surface of the first straight plate portion 51 and a second hot pressing plate 24 for pressing on the inner side surface of the second straight plate portion 52 are provided on the inner pressure module 22;

[0067] An outer mold hot pressing mechanism 3 located below the inner mold hot pressing mechanism 2. The outer mold hot pressing mechanism 3 includes a first outer pressure module 31 rotatably provided on the frame 1, a second outer pressure module 32 slidably provided on the first outer pressure module 31, a swing drive mechanism 33 connected between the frame 1 and the first outer pressure module 31, and a push-pull drive mechanism 34 connected between the first outer pressure module 31 and the second outer pressure module 32. A conveying mechanism 35 for conveying the corner plate 5 and a third hot pressing plate 36 for pressing on the outer side surface of the first straight plate portion 51 are provided on the first outer pressure module 31. A fourth hot pressing plate 37 for pressing on the outer side surface of the second straight plate portion 52 is provided on the second outer pressure module 32.

[0068] In the present invention, the above-mentioned corner plate 5 is composed of a first straight plate portion 51 and a second straight plate portion 52 that form an angle with each other. The angle between the first straight plate portion 51 and the second straight plate portion 52 can be one of an acute angle, a right angle (90 degrees), and an obtuse angle. The corner plate 5 is composed of an inner plate, an outer plate, and an intermediate layer (for example, the intermediate layer is made of rock wool material) sandwiched between the inner plate and the outer plate (for example, the inner plate or the outer plate is integrally formed by a steel plate). The cross-sections of the inner plate and the outer plate are both L-shaped. An adhesive is required to connect the inner plate and the intermediate layer, and an adhesive is also required to connect the outer plate and the intermediate layer. When the inner plate and the outer plate are pressed and heated, due to the solidification of the adhesive, the inner plate, the outer plate, and the intermediate layer are connected to each other to form the corner plate 5 applicable to assembled buildings (such as purification rooms). The inner pressure module 22 is provided with a first hot pressing plate 23 that presses on the inner side surface of the first straight plate portion 51 and a second hot pressing plate 24 that presses on the inner side surface of the second straight plate portion 52. And the first outer pressure module 31 is provided with a conveying mechanism 35 for conveying the corner plate 5 (the conveying direction of the conveying mechanism 35 is perpendicular to Figure 1 the paper surface) and a third hot pressing plate 36 that presses on the outer side surface of the first straight plate portion 51. The second outer pressure module 32 is provided with a fourth hot pressing plate 37 that presses on the outer side surface of the second straight plate portion 52. When the lifting drive mechanism 21 drives the inner pressure module 22 to move downward, the inner pressure module 22, the first outer pressure module 31, and the second outer pressure module 32 can clamp the entire corner plate 5 at the same time. Subsequently, the first hot pressing plate 23 presses on the inner side surface of the first straight plate portion 51, the second hot pressing plate 24 presses on the inner side surface of the second straight plate portion 52, the third hot pressing plate 36 presses on the outer side surface of the first straight plate portion 51, and the fourth hot pressing plate 37 presses on the outer side surface of the second straight plate portion 52. After a preset time, the assembled corner plate 5 is hot-pressed into shape.

[0069] As a method of using the above-mentioned hot press for producing corner plates:

[0070] S1, the inner die hot pressing mechanism 2 and the outer die hot pressing mechanism 3 are restored to the initial state (see specifically Figure 2 );

[0071] S2, the conveying mechanism 35 conveys the assembled corner plate 5 to the third hot pressing plate 36;

[0072] S3, driven by the push-pull drive mechanism 34, the second outer pressure module 32 moves towards the conveying mechanism 35 until the fourth hot pressing plate 37 is close to the outer side surface of the second straight plate portion 52;

[0073] S4, driven by the swing drive mechanism 33, the first outer pressure module 31 rotates relative to the frame 1 until the third hot pressing plate 36 is parallel to the first hot pressing plate 23 and the fourth hot pressing plate 37 is parallel to the second hot pressing plate 24 (see specifically Figure 3 );

[0074] S5. Driven by the lifting drive mechanism 21, the inner pressure module 22 moves closer to the first outer pressure module 31 and the second outer pressure module 32 until the third hot pressing plate 36 and the first hot pressing plate 23 clamp the first straight plate portion 51 of the corner plate 5 and the fourth hot pressing plate 37 and the second hot pressing plate 24 clamp the second straight plate portion 52 of the corner plate 5.

[0075] S6. The first hot pressing plate 23, the second hot pressing plate 24, the third hot pressing plate 36 and the fourth hot pressing plate 37 apply pressure and heat to the corner plate 5 for a preset time.

[0076] S7. Driven by the lifting drive mechanism 21, the inner pressure module 22 moves upward.

[0077] S8. The conveying mechanism 35 outputs the hot-pressed corner plate 5 out of the hot press.

[0078] Therefore, the hot press for producing corner plates of the present invention can automatically complete the input, pressing, heating, and output of the corner plate 5, ensure the forming quality of the corner plate 5, and reduce the labor cost of producing the corner plate 5.

[0079] As Figure 1 shown, in order to control the forming thickness of the above-mentioned corner plate 5, the hot press further includes a plate thickness detector 4. The plate thickness detector 4 is arranged on the inner die hot pressing mechanism 2 or the outer die hot pressing mechanism 3. The plate thickness detector 4 is used to detect the distance between the first hot pressing plate 23 and the third hot pressing plate 36 or the distance between the second hot pressing plate 24 and the fourth hot pressing plate 37.

[0080] In order to simplify the structure of the above-mentioned lifting drive mechanism 21, the lifting drive mechanism 21 includes a pressurizing telescopic cylinder 211 and a lifting telescopic cylinder 212. The cylinder body of the pressurizing telescopic cylinder 211 is arranged on the top of the frame 1 and the piston rod of the pressurizing telescopic cylinder 211 is connected to the inner pressure module 22. The cylinder body of the lifting telescopic cylinder 212 is arranged on the top of the frame 1 and the piston rod of the lifting telescopic cylinder 212 is connected to the inner pressure module 22.

[0081] In order to enable the above-mentioned first outer pressure module 31 to rotate relative to the frame 1, the frame 1 includes a main frame 11 and a rotating support frame 12 provided at the bottom of the main frame 11. The rotating support frame 12 is hinged to the first outer pressure module 31 through a rotating shaft 13.

[0082] In order to simplify the structure of the above-mentioned main frame 11, the main frame 11 includes an upper cross beam 111 for installing the inner die hot pressing mechanism 2 and a lower cross beam 112 for installing the outer die hot pressing mechanism 3. Support columns 113 are arranged between the upper cross beam 111 and the lower cross beam 112.

[0083] As Figure 4As shown in the figure, in order to prevent the adhesive in the assembled corner plate 5 from overflowing, the included angle between the conveying surface of the conveying mechanism 35 and the horizontal plane is an acute angle. Specifically, when the first external pressing module 31 is in the initial state, the included angle between the conveying surface of the conveying mechanism 35 and the horizontal plane is a first acute angle (for example, 10 degrees). When the first external pressing module 31 presses on the corner plate 5, the included angle between the conveying surface of the conveying mechanism 35 and the horizontal plane is a second acute angle, and the second acute angle is greater than the first acute angle.

[0084] As Figure 4 shown in the figure, in order to facilitate the arrangement of the third hot pressing plate 36, the conveying mechanism 35 includes a motor 351, a conveyor roller 352 drivingly connected to the motor 351, and a conveyor belt 353 sleeved on the conveyor roller 352. The third hot pressing plate 36 is located on the side of the conveyor belt 353 facing away from the first hot pressing plate 23. During hot pressing, the third hot pressing plate 36 indirectly abuts against the corner plate 5 through the conveyor belt 353.

[0085] In order to enable sliding fit between the second external pressing module 32 and the first external pressing module 31, a guide rail 311 and a slider 312 slidably fitted with the guide rail 311 are provided on the first external pressing module 31. The guide rail 311 is located on one side of the conveying mechanism 35, and the extending direction of the guide rail 311 is perpendicular to the conveying direction of the conveying mechanism 35. The slider 312 is connected to the second external pressing module 32.

[0086] In order to enable the first external pressing module 31 to rotate relative to the frame 1, the swing driving mechanism 33 is an inclined top telescopic cylinder 331, and both ends of the inclined top telescopic cylinder 331 are respectively hinged to the first external pressing module 31 and the frame 1 through first connecting lugs 332.

[0087] In order to enable the second external pressing module 32 to move linearly relative to the first external pressing module 31, the push-pull driving mechanism 34 includes a mounting bracket 343 and a push-pull telescopic cylinder 341. The mounting bracket 343 is provided on the first external pressing module 31, and both ends of the push-pull telescopic cylinder 341 are respectively hinged to the mounting bracket 343 and the second external pressing module 32 through second connecting lugs 342.

[0088] In summary, the hot press of the present invention for producing corner plates can automatically complete the input, pressing, heating, and output of corner plates, ensure the forming quality of corner plates, and reduce the labor cost of producing corner plates. Therefore, the present invention effectively overcomes various disadvantages in the prior art and has high industrial utilization value.

[0089] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
