Description

Technical Field

[0001] The utility model belongs to the technical field of hot bending and shaping of plates, and specifically relates to a hot bending and shaping device for plate shaping. Background Technique

[0002] Hot pressing is a process of heating and pressing the formed slab simultaneously to make fiber plates with certain mechanical strength and water resistance. Whether it is wet production of hard boards or semi-hard boards, or dry production of hard boards or medium density fiberboards, they all need to go through hot pressing to become plates, and then the hot-pressed plates need to be bent according to subsequent production requirements.

[0003] When making a slab into a plate by hot pressing and bending it according to requirements, it is necessary to first hot press the slab through a hot pressing device to form a plate, and then bend the formed plate through a bending machine. The above operation process requires the cooperation of two sets of devices to complete, resulting in low work efficiency in the production process of hot pressing and bending the slab into a suitable arc.

Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments.

[0028] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc. indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as a limitation to the utility model.

[0029] Please refer to Figures 1-6 As shown, the present utility model is a hot bending and shaping device for sheet metal modeling, including a bottom plate 1. A support plate 2 is fixedly connected to the top of the bottom plate 1. A support heating roller 3 is fixedly connected to one side of the support plate 2. Lifting heating plates 4 are rotatably connected to both sides of the support heating roller 3. A lifting rotation assembly 5 is arranged at the bottom of the lifting heating plate 4. An extrusion heating roller 6 is arranged above the support heating roller 3. Extrusion heating plates 7 are rotatably connected to both sides of the extrusion heating roller 6. Extrusion driving assemblies 8 are arranged on the upper side of the extrusion heating roller 6 and the bottom of the lifting heating plate 4. Positioning assemblies 9 are arranged on one side and inside of the lifting heating plate 4.

[0030] Place the slab on the top of the lifting heating plate 4. At this time, the position of the slab that needs to be bent under the positioning of the positioning component 9 is exactly at the top of the supporting heating roller 3. Then, drive the two extrusion heating plates 7 and the extrusion heating roller 6 through the extrusion driving component 8, so that the extrusion heating plate 7 and the extrusion heating roller 6 extrude the slab on the top of the lifting heating plate 4 and the supporting heating roller 3. With the cooperation of the supporting heating roller 3, the lifting heating plate 4, the extrusion heating roller 6 and the extrusion heating plate 7, hot pressing operation can be carried out on the slab. While hot pressing, lift the lifting heating plate 4 through the lifting rotation component 5. The two sides of the slab rotate upward under the drive of the lifting heating plate 4 and the extrusion heating plate 7, so that the supporting heating roller 3 and the extrusion heating roller 6 cooperate to carry out bending operation on the slab being hot pressed.

[0031] Through the extrusion driving component 8, the supporting heating roller 3, the lifting heating plate 4, the extrusion heating roller 6 and the extrusion heating plate 7 cooperate to carry out hot pressing operation on the slab. At the same time, under the lifting of the lifting rotation component 5, the lifting heating plate 4 and the extrusion heating plate 7 can rotate on both sides of the corresponding supporting heating roller 3 and extrusion heating roller 6, so that the two sides of the slab extruded by the lifting heating plate 4 and the extrusion heating plate 7 can rotate. And at this time, the position of the slab that needs to be bent can be bent under the extrusion of the supporting heating roller 3 and the extrusion heating roller 6. In summary, while hot pressing the slab, it can be bent and shaped, so that it forms an arc structure that will not rebound. At the same time, the two working processes are carried out simultaneously, so that the working efficiency in the production of the plate is also improved.

[0032] In one embodiment, for the above-mentioned lifting rotation component 5, the lifting rotation component 5 includes a mounting plate 501. The mounting plate 501 is fixedly connected to the top of the bottom plate 1. A mounting seat 502 is rotatably connected inside the mounting plate 501. The top of the mounting seat 502 is fixedly connected with a lifting hydraulic cylinder 503. The bottom of the lifting heating plate 4 is fixedly connected with a connecting plate 504. The output end of the lifting hydraulic cylinder 503 is rotatably connected with the connecting plate 504. A plurality of lifting hydraulic cylinders 503 are symmetrically arranged on the top of the bottom plate 1.

[0033] By driving the lifting hydraulic cylinder 503, the overall length of the lifting hydraulic cylinder 503 becomes longer. The two ends of the lifting hydraulic cylinder 503 rotate inside the corresponding mounting plate 501 and connecting plate 504. At the same time, the lifting heating plate 4 can rotate on one side of the supporting heating roller 3. Four lifting hydraulic cylinders 503 are arranged on the top of the bottom plate 1 corresponding to the two lifting heating plates 4. Coupled with the fact that the supporting heating roller 3 can support the lifting heating plate 4, the overall stability of the lifting heating plate 4 can be guaranteed when it rotates under the support of a plurality of lifting hydraulic cylinders 503 and the supporting heating roller 3.

[0034] In one embodiment, for the above-mentioned extrusion driving assembly 8, the extrusion driving assembly 8 includes an L-shaped support plate 801, the L-shaped support plate 801 is fixedly connected to the top of the bottom plate 1, a lifting hydraulic cylinder 802 is fixedly connected to the top of the L-shaped support plate 801, the output end of the lifting hydraulic cylinder 802 penetrates through the L-shaped support plate 801 and is fixedly connected to an installation frame 803, the extrusion heating roller 6 is fixedly connected to the installation frame 803, the extrusion driving assembly 8 further includes a moving rod 804, the moving rod 804 is movably connected to the L-shaped support plate 801, the bottom end of the moving rod 804 is fixedly connected to the top of the installation frame 803, a pulling hydraulic cylinder 805 is fixedly connected to the bottom of the jacking heating plate 4, and the output end of the pulling hydraulic cylinder 805 penetrates through the jacking heating plate 4 and is fixedly connected to the extrusion heating plate 7.

[0035] By driving the lifting hydraulic cylinder 802, the lifting hydraulic cylinder 802 can drive the installation frame 803 to move downward, so that the extrusion heating roller 6 inside the installation frame 803 can extrude the slab placed on the top of the support heating roller 3. At the same time, the pulling hydraulic cylinder 805 can pull the extrusion heating plate 7 downward, so that the extrusion heating plate 7 can extrude the slab placed on the top of the jacking heating plate 4. The overall models and output powers of the lifting hydraulic cylinder 802 and the pulling hydraulic cylinder 805 are the same, and when hot-pressing the slab, the lifting hydraulic cylinder 802 and the pulling hydraulic cylinder 805 drive the extrusion heating roller 6 and the extrusion heating plate 7 at the same time, so that the extrusion heating roller 6 and the extrusion heating plate 7 can move downward synchronously. This setting ensures the effect of hot-pressing the slab. At the same time, setting the pulling hydraulic cylinder 805 at the bottom of the jacking heating plate 4 can enable the extrusion heating plate 7 to rotate together when the jacking hydraulic cylinder 503 jacks up the jacking heating plate 4 and makes it rotate, so that the overall hot-pressing working state of the slab between the jacking heating plate 4 and the extrusion heating plate 7 will not be damaged.

[0036] In one embodiment, for the above-mentioned positioning component 9, the positioning component 9 includes a longitudinal positioning plate 901, the longitudinal positioning plate 901 is fixedly installed at the rear side of the lifting heating plate 4, an adjustment groove 902 is formed at the top of the lifting heating plate 4, the adjustment groove 902 penetrates through the extrusion heating plate 7, a transverse positioning rod 903 is movably connected inside the adjustment groove 902, the positioning component 9 further includes a fixing plate 904, two fixing plates 904 are fixedly connected to the bottom plate 1, a screw rod 905 is rotatably connected between the two fixing plates 904, the transverse positioning rod 903 is threadedly connected to the screw rod 905, a motor 906 is fixedly installed on one side of the fixing plate 904, the output end of the motor 906 is fixedly connected to the screw rod 905, a fixing rod 907 is fixedly connected between the two fixing plates 904, and the outer surface of the fixing rod 907 is movably connected to the transverse positioning rod 903.

[0037] By driving the motor 906, the screw rod 905 can drive the transverse positioning rod 903. At this time, the transverse positioning rod 903 can slide inside the adjustment groove 902 under the guidance of the fixing rod 907 and move to a suitable position. With the setting of the longitudinal positioning plate 901, when the slab is placed on the support heating roller 3 and the lifting heating plate 4, the side of the slab can directly contact the transverse positioning rod 903 and the longitudinal positioning plate 901. With the assistance of the longitudinal positioning plate 901, the slab can be kept horizontal with the side of the lifting heating plate 4. Under the positioning of the transverse positioning rod 903, the position where the slab needs to be bent can be directly above the support heating roller 3. The above settings ensure the effect of bending the slab. At the same time, the adjustment grooves 902 are provided on both the lifting heating plate 4 and the extrusion heating plate 7, so that the extrusion heating plate 7 will not be hindered when extruding the slab on the lifting heating plate 4.

[0038] In one embodiment, for the above-mentioned lifting heating plate 4, connection rings 10 are fixedly connected to one side of both the lifting heating plate 4 and the extrusion heating plate 7. The lifting heating plate 4 and the extrusion heating plate 7 are rotatably connected to the shaft heads of the corresponding support heating roller 3 and extrusion heating roller 6 through the connection rings 10. The top of the lifting heating plate 4 and the outer surface of the support heating roller 3 are on the same horizontal plane, and the bottom of the extrusion heating plate 7 and the outer surface of the extrusion heating roller 6 are on the same horizontal plane.

[0039] When the jacking heating plate 4 and the extrusion heating plate 7 can rotate on both sides of the corresponding support heating roller 3 and extrusion heating roller 6 with the assistance of the connecting ring 10, and the connecting rings 10 on the two jacking heating plates 4 and extrusion heating plates 7 are staggeredly arranged on the shaft heads of the corresponding support heating roller 3 and extrusion heating roller 6, this setting enables the top of the support heating roller 3 and the jacking heating plate 4 to remain flat, while the bottom of the extrusion heating roller 6 and the extrusion heating plate 7 can remain flat. The above setting enables the support heating roller 3, the jacking heating plate 4, the extrusion heating roller 6, and the extrusion heating plate 7 to be in relatively close contact with the top and bottom of the slab during hot pressing of the slab, thereby ensuring the effect during hot pressing of the slab.

[0040] In summary, by means of the above technical solution of the present utility model, the motor 906 drives the screw 905, so that the transverse positioning rod 903 moves inside the adjustment groove 902 under the drive of the screw 905 and the guidance of the fixed rod 907 and moves to a suitable position. Then, the slab is placed on the top of the support heating roller 3 and the jacking heating plate 4, and the side of the slab is directly in contact with the transverse positioning rod 903 and the longitudinal positioning plate 901. Next, the lifting hydraulic cylinder 802 and the pulling hydraulic cylinder 805 are driven simultaneously. At this time, the lifting hydraulic cylinder 802 drives the extrusion heating roller 6 to move downward through the mounting frame 803 and extrude the slab placed on the top of the support heating roller 3, while the pulling hydraulic cylinder 805 pulls the extrusion heating plate 7 downward, and enables the extrusion heating plate 7 to extrude the slab placed on the top of the jacking heating plate 4. Finally, the jacking hydraulic cylinder 503 is driven, so that the overall length of the jacking hydraulic cylinder 503 becomes longer, and at the same time, the jacking heating plate 4 cooperates with the extrusion heating plate 7 under the jacking of the jacking hydraulic cylinder 503 to drive the side of the slab being hot pressed to rotate and be bent under the cooperation of the support heating roller 3 and the extrusion heating roller 6.

[0041] Through the above technical solutions: 1. By driving the extrusion drive assembly 8, the support heating roller 3, the lifting heating plate 4, the extrusion heating roller 6 and the extrusion heating plate 7 cooperate to perform hot pressing operations on the slab. At the same time, under the lifting of the lifting rotation assembly 5, the lifting heating plate 4 and the extrusion heating plate 7 can rotate on both sides of the corresponding support heating roller 3 and extrusion heating roller 6, so that both sides of the slab extruded by the lifting heating plate 4 and the extrusion heating plate 7 can rotate. At this time, the position where the slab needs to be bent can be bent under the extrusion of the support heating roller 3 and the extrusion heating roller 6. In summary, while hot pressing the slab, it can be bent and shaped, so that an arc structure that will not rebound is formed. At the same time, the two working processes are carried out simultaneously, so that the working efficiency in the production of the plate is also improved; 2. By setting the longitudinal positioning plate 901 and the transverse positioning rod 903, after the side of the slab contacts the longitudinal positioning plate 901, it can be kept horizontal with the side of the lifting heating plate 4. After the other side of the slab contacts the transverse positioning rod 903, the position where the slab needs to be bent can be directly at the top of the support heating roller 3. At the same time, the transverse positioning rod 903 can be automatically adjusted inside the adjustment groove 902 under the drive of the motor 906 and the screw 905. This setting enables the longitudinal positioning plate 901 to be adjusted according to the position where the slab needs to be bent. The above settings result in better bending effect of the slab in the hot pressing state.
