Abstract
Description
Technical Field
[0001] This utility model belongs to the field of press technology, and in particular relates to a vacuum chamber and a press. Background Technology
[0002] A vacuum hot press is a mechanical device that uses heat and pressure to tightly bond multiple layers of materials together in a vacuum. Since the front of the hot press is the material inlet and outlet channel, the opening and closing of the front door is done automatically. Generally, the opening and closing of the door is done by moving a cylinder, and then the door is pressed tightly before the vacuum is drawn.
[0003] In presses, the closing mechanism of the sealing doors is crucial for ensuring the normal operation and safety of the equipment. Currently, presses typically have only two doors: a front vacuum door and a rear vacuum door. The front vacuum door is lifted by a belt and guided by a guide rail, while the rear vacuum door often relies on a cantilever to rotate, causing the entire rear vacuum door to move. The rear vacuum door's overall structure depends solely on the cantilever's opening and closing. The large size of the press results in a heavy rear vacuum door, and the excessively long cantilever increases its deflection, leading to problems such as uneven rotation, jamming, and sagging. Therefore, it is necessary to design a vacuum chamber that reduces the weight of a single rear vacuum door, thereby reducing cantilever deflection and lowering the probability of uneven rotation, jamming, and sagging. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a vacuum chamber and a compressor to address the existing problems of unsmooth rotation, easy jamming, and easy sagging of the rear vacuum door.
[0005] To address the aforementioned issues, this utility model provides a vacuum chamber, comprising a frame and at least two rear vacuum door mechanisms arranged horizontally. The frame has a chamber opening, and each rear vacuum door mechanism includes a rotating arm assembly and a rear vacuum door assembly. The rear vacuum door assembly is rotatably mounted on the frame via the rotating arm assembly, allowing the rear vacuum door assembly to switch between an open state and a closed state. When all the rear vacuum door assemblies of the rear vacuum door mechanisms are switched to the closed state, they can seal the chamber opening.

[0007] Optionally, the swing arm assembly includes a mounting base and a cantilever, the mounting base is mounted on the frame, one end of the cantilever is rotatably mounted on the mounting base about a first axis, and the rear vacuum door assembly is mounted on the other end of the cantilever.
[0008] Optionally, the rear vacuum door assembly includes a rear vacuum door and a pivot, the pivot being mounted on the rear vacuum door and rotatably mounted on the cantilever about a second axis, wherein the first axis and the second axis are parallel.
[0009] Optionally, the end of the rotating shaft is provided with a connecting block, which is installed on the rear vacuum door.
[0010] Optionally, the mounting base is provided with two spaced-apart mounting plates, and the cantilever is rotatably mounted between the two mounting plates.
[0011] Optionally, the swing arm assembly further includes a hinge shaft, the axis of which coincides with the first axis, and the cantilever is rotatably mounted on the mounting base via the hinge shaft.
[0012] Optionally, a partition is provided across the frame at the location of the compartment opening, and one side of each of the two adjacent rear vacuum door assemblies can be sealed and covered by the two sides of the partition.

[0015] Optionally, the rear vacuum door mechanism is rotatably mounted on the frame about a vertical axis.
[0016] Optionally, the swing arm assembly is mounted on the upper surface of the frame.
[0017] In another aspect, this utility model embodiment provides a press, including a press main frame, a pressing plate mechanism and a vacuum chamber as described above. The frame is fixed to the press main frame, and the pressing plate mechanism is installed inside the press main frame. The pressing plate mechanism is used to press the sheet metal.
[0018] As a further improvement to the above technical solution:

[0032] like Figures 1 to 5 As shown, an embodiment of the present invention provides a vacuum chamber 100, which includes a frame 110 and at least two rear vacuum door mechanisms 120 arranged horizontally. The frame 110 has a chamber opening 111. The rear vacuum door mechanism 120 includes a rotating arm assembly and a rear vacuum door assembly. The rotating arm assembly is installed on the frame 110, and the rear vacuum door assembly is installed on the rotating arm assembly. The vacuum door assembly is rotatably installed on the frame 110 through the rotating arm assembly, so that the vacuum door assembly can switch between an open state and a closed state. When the vacuum door assemblies of all vacuum door mechanisms are switched to the closed state, they can seal the chamber opening 111.
[0033] During installation, the rear vacuum door assemblies of each rear vacuum door mechanism 120 are mounted onto the frame 110 via the swing arm assembly. Please refer to the following for details. Figure 1 and Figure 2 When it is necessary to seal the opening 111 of the frame 110, the rotating arm assembly is driven to rotate manually or by other means so that the rear vacuum door assembly seals and closes onto the frame 110. The rear vacuum door assemblies of each rear vacuum door mechanism 120 cooperate with each other to seal the opening 111. Please refer to the following for details. Figure 3 and Figure 4 When it is necessary to open the hopper 111 of the frame 110, the rotating arm assembly is driven to rotate by manual or other means so that the rear vacuum door assembly moves away from the frame 110. The rear vacuum door assemblies of each rear vacuum door mechanism 120 cooperate with each other to open the hopper 111, thereby facilitating the unloading of materials inside the frame 110.
[0034] In a vacuum chamber 100 provided in one embodiment of the present invention, since at least two rear vacuum door mechanisms 120 are arranged in opposite directions along the horizontal direction, the rear vacuum door components of each rear vacuum door mechanism 120 can cooperate with each other to seal the chamber opening 111. Therefore, the weight of a single rear vacuum door 123 can be reduced, thereby reducing the deflection of the cantilever 122 and reducing the probability of the rear vacuum door 123 rotating unevenly, getting stuck, or sagging.
[0035] In one specific embodiment, the vacuum chamber 100 provided by this utility model includes a frame 110 and two rear vacuum door mechanisms 120. Each rear vacuum door mechanism 120 includes a rotating arm assembly and a rear vacuum door assembly. The rotating arm assembly is mounted on the frame 110, and the rear vacuum door assembly is mounted on the rotating arm assembly. The rotating arm assembly can drive the rear vacuum door assembly to rotate in a vertical direction. That is, the two rear vacuum door assemblies are arranged in the form of double doors.
[0036] When it is necessary to seal the opening 111 of the frame 110, the rotating arm assembly is driven to rotate manually or otherwise, so that the rear vacuum door assembly moves horizontally to seal and cover the frame 110. The rear vacuum door assemblies of each rear vacuum door mechanism 120 cooperate with each other to seal the opening 111. When it is necessary to open the opening 111 of the frame 110, the rotating arm assembly is driven to rotate manually or otherwise, so that the rear vacuum door assembly moves horizontally away from the frame 110. The rear vacuum door assemblies of each rear vacuum door mechanism 120 cooperate with each other to open the opening 111.
[0037] Of course, it is understood that the vacuum chamber 100 may also include other numbers of rear vacuum door mechanisms 120, such as three, etc., and the rear vacuum door assemblies of the three rear vacuum door mechanisms 120 can cooperate with each other to seal the chamber opening 111.
[0038] In one embodiment of this utility model, the vacuum chamber 100 is provided. For details, please refer to the specific description. Figures 1 to 5 The rotating arm assembly includes a mounting base 121 and a cantilever 122. The mounting base 121 is mounted on the frame 110. One end of the cantilever 122 is rotatably mounted on the mounting base 121 about a first axis, and the rear vacuum door assembly is mounted on the other end of the cantilever 122. When it is necessary to seal the opening 111 of the frame 110, the cantilever 122 is driven to rotate relative to the mounting base 121 by manual operation or other means, so that the rear vacuum door assembly moves horizontally to seal and cover the frame 110. The rear vacuum door assemblies of each rear vacuum door mechanism 120 cooperate with each other to seal the opening 111. When it is necessary to open the opening 111 of the frame 110, the cantilever 122 is driven to rotate in the opposite direction relative to the mounting base 121 by manual operation or other means, so that the rear vacuum door assembly moves horizontally away from the frame 110. The rear vacuum door assemblies of each rear vacuum door mechanism 120 cooperate with each other to open the opening 111.
[0039] In a specific embodiment, please refer to the following. Figure 5 The swing arm assembly also includes a hinge shaft 125, through which the cantilever 122 is rotatably mounted to the mounting base 121. Of course, it is understood that the cantilever 122 can also be rotatably mounted to the mounting base 121 in other ways, such as by a pin and a pin hole.
[0040] In one embodiment of this utility model, the vacuum chamber 100 is provided. For details, please refer to the specific description. Figures 1 to 5 The rear vacuum door assembly includes a rear vacuum door 123 and a rotating shaft 124. The rotating shaft 124 is mounted on the rear vacuum door 123 and is rotatably mounted on the cantilever 122 about a second axis, with the first and second axes parallel. Because this structure allows the rear vacuum door 123 to rotate relative to the cantilever 122 via the rotating shaft 124, the opening area of the compartment 111 can be expanded when the rear vacuum door assemblies of each rear vacuum door mechanism 120 cooperate to open the compartment opening 111, thus preventing the rear vacuum door 123 from affecting the opening area of the compartment opening 111.
[0041] In this embodiment, the rotating arm assembly can drive the rear vacuum door assembly to rotate in a vertical direction, with both the first and second axes being vertical. The rotating arm assembly is mounted on the upper surface of the frame 110. Of course, it is understood that the rotating arm assembly can also be mounted in other locations on the frame 110, such as the side wall or the lower surface.
[0042] When it is necessary to seal the opening 111 of the frame 110, the cantilever 122 is driven to rotate relative to the mounting base 121 by manual or other means, so that the rear vacuum door assembly moves horizontally, and the rear vacuum door 123 rotates relative to the cantilever 122 about the second axis through the rotating shaft 124, until the rear vacuum door 123 seals and covers the frame 110, and the rear vacuum door assemblies of each rear vacuum door mechanism 120 cooperate with each other to seal the opening 111; when it is necessary to open the opening 111 of the frame 110, the cantilever 122 is driven to rotate in the opposite direction relative to the mounting base 121 by manual or other means, so that the rear vacuum door assembly moves horizontally, and the rear vacuum door 123 rotates relative to the cantilever 122 about the second axis through the rotating shaft 124, until the rear vacuum door 123 moves away from the frame 110, and the rear vacuum door assemblies of each rear vacuum door mechanism 120 cooperate with each other to open the opening 111.
[0043] In this embodiment, a connecting block 126 is provided at the end of the rotating shaft 124, and the connecting block 126 is installed on the rear vacuum door 123. The mounting base 121 is provided with two spaced-apart mounting plates 127, and the cantilever 122 is rotatably installed between the two mounting plates 127.
[0044] In one embodiment of the vacuum chamber 100 provided by this utility model, further details can be found in the following references. Figure 3 and Figure 5 A partition 112 is provided across the frame 110 at the location of the compartment opening 111. One side of each of two adjacent rear vacuum door assemblies can be sealed and covered by the partition 112. When the rear vacuum door assemblies of each rear vacuum door mechanism 120 cooperate with each other to seal the compartment opening 111, one side of each of two adjacent rear vacuum door assemblies can be sealed and covered by the partition 112, thereby improving the sealing degree.
[0045] For further details, please refer to [link / reference]. Figure 3 and Figure 5 Each partition 112 has partition seals 113 on both sides near the rear vacuum door assembly. The rear vacuum door assembly can seal and cover the partition 112 by pressing the partition seals 113. A frame seal 114 is provided on the frame 110 at the outer edge of the opening 111. The rear vacuum door assembly can seal and cover the frame 110 by pressing the frame seal 114. When the rear vacuum door assemblies of each rear vacuum door mechanism 120 cooperate to seal the opening 111, the rear vacuum door assembly can seal and cover the partition 112 by pressing the partition seals 113, and the rear vacuum door assembly can seal and cover the frame 110 by pressing the frame seal 114. The partition seals 113 improve the sealing between the rear vacuum door assembly and the partition 112, and the frame seals 114 improve the sealing between the rear vacuum door assembly and the frame 110.
[0046] In this embodiment, both the partition seal 113 and the frame seal 114 are flexible sealing strips, preferably rubber sealing strips. Of course, it is understood that the partition seal 113 and the frame seal 114 can also be seals of other structures.
[0047] In another embodiment of this utility model, a press is provided, which includes a main frame, a pressing plate mechanism, and a vacuum chamber 100 as provided in any of the above embodiments. The frame is fixed to the rear side of the main frame, and a front vacuum door mechanism is provided on the front side of the main frame.
