Description

Technical Field

[0001] This utility model belongs to the field of hot pressing forming, and more specifically, this utility model relates to a hydraulic press for hot pressing forming a V-shaped aluminum plate integral plate. Background Technology

[0002] Hot pressing is a simple and common processing method in the plastics processing industry. It mainly involves heating and processing a mold, injecting a sample, and using pressure to fix the mold on a heating plate. The melting temperature and time of the sample are controlled to achieve melting, hardening, cooling, and then removing the mold to complete the product. However, most aluminum plates on the market are currently made using cold glue and its matching cold pressing process.

[0003] Patent document CN211074425U discloses a pressure forming device for an integrated thermal insulation and decorative panel, including a model platform. Support legs are symmetrically fixedly connected to the left and right sides of the bottom of the model platform, and support columns are symmetrically fixedly connected to the left and right sides of the model platform. A crossbeam is set at the center of the top of the model platform, and a hydraulic push rod is fixedly installed at the center of the bottom of the crossbeam. First anti-friction rings are symmetrically arranged on the left and right sides of the top of the crossbeam. This utility model's pressure forming device for an integrated thermal insulation and decorative panel, through the coordinated operation of a support sleeve, slide groove, connecting rod, slider, and return spring, forms a buffer area. Combined with the output pressure and contraction deformation of the hydraulic push rod, it provides further support to the pressure plate with elastic force. Even when the hydraulic push rod retracts, it can still hold the pressure plate, thus saving energy. It can be integrated into existing composite wall panel production lines, improving the processing efficiency of composite partition walls and saving production capacity and costs.

[0004] The aforementioned patent document states that the traditional cold pressing process and cold glue are used for pressure forming of the integrated plate; however, the cold pressing process and cold glue will cause pressure curing, and the cold pressing process requires a very long time; at the same time, the cold pressing process mainly consists of two steps: spraying glue and pressing down, which will result in uneven surface flatness of the aluminum plate. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a hot pressing hydraulic press for forming V-shaped aluminum plate integral panels, which reduces the internal stress of the integral panel and improves the surface flatness of the integral panel.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a hot pressing hydraulic press for integral flat aluminum plates, comprising a frame, a pressing block, a working part, and a control system. The pressure mechanism is located at the top of the frame, and the control system controls the entire working process of the hydraulic press. The working part includes multiple parallel pressing plates, which are connected by a telescopic mechanism. The connected pressing plates can move up and down on the Z-axis. The bottom pressing plate is directly fixed to the frame, and the top pressing plate is directly fixedly connected to the pressing block. In addition to being connected to the pressure mechanism, the pressing block is also provided with a stabilizing mechanism. The pressing block and the stabilizing mechanism are movably connected, and the direction of movement is up and down on the Z-axis.

[0007] This utility model discloses a hot-pressing hydraulic press for integral flat aluminum plates. The telescopic mechanism includes multiple connecting blocks and multiple connecting shafts. Each connecting block is provided with a connecting hole. The connected connecting blocks are arranged in a stepped manner and are connected by a connecting shaft. The connecting blocks and the pressing blocks are fixedly connected. Except for the bottom connecting block which is fixedly connected to the frame, the other connecting blocks can slide on the connecting shaft. The top of the connecting shaft is provided with a capping cylinder, the diameter of which is larger than the diameter of the connecting hole.

[0008] This utility model discloses a hot pressing hydraulic press for integral flat aluminum plate forming. The stabilizing mechanism includes a rack, gears, a drive shaft, and bearing seats. The rack is fixedly installed on the side wall of the vertical connecting column of the frame. The bearing seats are installed at the four corners of the top plane of the pressing block. Both ends of the drive shaft are installed on the bearing seats, and gears are installed at the ends that extend through the bearing seats. The gears mesh with the rack.

[0009] This utility model discloses a hot pressing hydraulic press for integral forming of a flat aluminum plate. The pressure mechanism consists of multiple parallel hydraulic cylinders, which are mounted on the top of the machine frame. The free extension and retraction ends of the hydraulic cylinders are fixedly connected to the pressure block.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] 1. The solidification time of a hot-press forming hydraulic press is four hours, while that of a cold-press forming device is only five minutes.

[0012] 2. When applying adhesive, the hot-press forming hydraulic press spreads it more evenly, resulting in a higher surface flatness of the integrated panel.

[0013] 3. Hot pressing hydraulic presses can, to some extent, solve the stress problems generated during the processing of integrated aluminum plates, which is something that cold pressing cannot do.

[0014] The present invention will be described in more detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0019] The following description, with reference to the accompanying drawings, further details the specific implementation methods of this utility model, including the shape and structure of each component, the relative positions and connections between the parts, the function and working principle of each part, the manufacturing process, and the operation and use methods, so as to help those skilled in the art to have a more complete, accurate, and in-depth understanding of the utility model concept and technical solution.

[0020] like Figure 1 The hot pressing hydraulic press shown includes a frame 1, a pressure block 3, a pressure mechanism, a working part, and a control system. The pressure mechanism is located at the top of the frame 1, and the control system controls the entire working process of the hydraulic press. The working part includes multiple parallel pressure plates 4, which are connected to each other by a telescopic mechanism. The connected pressure plates 4 can move up and down on the Z-axis. The bottom pressure plate 4 is directly fixed to the frame 1, and the top pressure plate 4 is directly fixed to the pressure block 3. In addition to being connected to the pressure mechanism, the pressure block 3 is also equipped with a stabilizing mechanism. The pressure block 3 and the stabilizing mechanism are movably connected, and the movement direction is up and down on the Z-axis.

[0021] Based on the above settings, the control system of this device belongs to existing technology, so the relevant details will not be elaborated upon.

[0022] like Figure 2 The telescopic mechanism shown includes multiple connecting blocks 9 and multiple connecting shafts 10. Each connecting block 9 is provided with a connecting hole. The connected connecting blocks 9 are arranged in a stepped manner and are connected by a connecting shaft 10. The connecting blocks 9 and the pressure block 3 are fixedly connected. Except for the bottom connecting block 9 which is fixedly connected to the frame 1, the other connecting blocks 9 can slide on the connecting shaft 10. The top of the connecting shaft 10 is provided with a capping cylinder, the diameter of which is larger than the diameter of the connecting hole.

[0023] like Figure 1The stabilizing mechanism shown includes a rack 5, a gear 7, a drive shaft 6, and a bearing seat 8. The rack 5 is fixedly mounted on the side wall of the vertical connecting column of the frame 1. The bearing seat 8 is located at the four corners of the top plane of the pressure block 3. Both ends of the drive shaft 6 are mounted on the bearing seat 8, and the ends of both ends that extend through the bearing seat 8 are equipped with gears 7, which mesh with the rack 5.

[0024] With the above settings, this hydraulic press can complete a full workflow even without a stabilizing mechanism. However, the presence of a stabilizing mechanism greatly increases the lifespan of the device and reduces the occurrence of accidents. Without a stabilizing mechanism, the Z-axis movement of the pressure block is controlled solely by hydraulic cylinders. The connecting block directly bears the pressure of multiple hydraulic cylinders, which may lead to breakage and cause the pressure block to fall directly onto the next layer. Due to the high temperature of the working environment, there is a risk of fire and other unforeseen risks. The stabilizing mechanism can control the speed of the pressure block and provide a certain amount of support.

[0025] like Figure 1 The pressure mechanism shown consists of multiple parallel hydraulic cylinders 2, which are mounted on the top of the frame 1. The free extension and retraction ends of the hydraulic cylinders 2 are fixedly connected to the pressure block 3.

[0026] Working principle and method

[0027] The flat aluminum integrated plate is placed on the pressure plate 4 of each layer. Then, the hydraulic press is turned on from the control system. The hydraulic cylinder 2 pushes the pressure block 3 downward. The pressure block 3 presses the pressure plate 4 downward. The pressure plates 4 of the last few layers are pressed together. When the hydraulic cylinder 2 reaches the set maximum elongation value, it enters the stabilization stage. After stabilizing for a period of time, the hydraulic cylinder 2 pulls the pressure block 3 upward. When it reaches the set value, the staff takes out the flat aluminum integrated plate, completing one process.

[0028] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
