Description

Technical Field

[0001] The present application relates to the technical field of pressing equipment, and in particular to a pressing machine. Background Art

[0002] A material press is a device that uses a hydraulic cylinder to drive a pressure plate downward, forcing high-viscosity materials out of a barrel. During this process, the platen and barrel can easily become misaligned, causing uneven force on the cylinder, platen, and barrel, shortening the life of the device. Furthermore, misalignment between the platen and barrel can easily lead to material leakage.

[0031] The following will clearly and completely describe the technical solutions of the embodiments of this application in conjunction with the accompanying drawings. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection requested by this application.

Therefore, they should not be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0033] In the description of the embodiments of the present application, it should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, replaceable connections, or integral connections. They can also refer to mechanical connections or electrical connections.

For those skilled in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0034] See also Figures 1 to 3 A material pressing machine provided in an embodiment of the present application includes: a hydraulic cylinder assembly 10 and a pressure plate assembly 20; an active cavity 201 is provided on the pressure plate assembly 20; the end of the hydraulic cylinder assembly 10 is located in the active cavity 201; the hydraulic cylinder assembly 10 is used to drive the pressure plate assembly 20 to move axially along the hydraulic cylinder assembly 10; in the active cavity 201, the pressure plate assembly 20 is slidable along the radial direction of the hydraulic cylinder assembly 10.

[0035] In this application, the axial direction of the hydraulic cylinder assembly 10 refers to the axial direction of the hydraulic cylinder 11 contained therein, that is, Figure 1 The radial direction of the hydraulic cylinder assembly 10 refers to the radial direction of the hydraulic cylinder 11 contained therein, that is, Figure 1 The positive and negative directions of the x-axis.

[0036] In this embodiment, the hydraulic cylinder assembly 10 extends into the active cavity 201, and its two axial sides can abut the pressure plate assembly 20, so that when the hydraulic cylinder assembly 10 expands and contracts in the axial direction, it can drive the pressure plate assembly 20 to expand and contract in the axial direction. There is a gap between the two radial sides of the hydraulic cylinder assembly 10 in the active cavity 201, so that when the center of the pressure plate assembly 20 and the barrel 60 are misaligned, the pressure plate assembly 20 can be moved radially to achieve centering of the pressure plate assembly 20 and the barrel 60.

[0037] It should be noted that the centering process of the pressure plate assembly 20 moving in the radial direction can be completed by the staff, or it can be completed by setting up a driving member to drive the pressure plate assembly 20 to move.

[0038] The pressing machine provided by this embodiment can complete the alignment of the pressure plate assembly 20 and the barrel 60 without disassembly, thereby completing a pressing process of the pressure plate assembly 20 and the barrel 60, and then replace the barrel 60 for the next pressing operation, avoiding the problems of uneven force and material leakage in the pressing machine.

[0039] In a more specific embodiment, the pressure plate assembly 20 includes: a pressure plate 21 and a pressure plate flange 22 ; the pressure plate flange 22 is fixed on the pressure plate 21 and forms an active cavity 201 with the pressure plate 21 .

[0040] In this embodiment, the pressure plate flange 22 can be a concave flange and encloses the above-mentioned movable cavity 201 with the pressure plate 21. The pressure plate flange 22 can be fixedly connected to the pressure plate 21 by bolts 23, and can be removed by removing the bolts 23 when replacement is required.

[0041] In one embodiment, the hydraulic cylinder assembly 10 includes: a hydraulic cylinder 11 and a cylinder flange 12; the cylinder flange 12 is embedded and fixed on the radial outer periphery of the hydraulic cylinder 11; the cylinder flange 12 is slidably arranged in the movable cavity 201 along the radial direction of the hydraulic cylinder assembly 10 relative to the pressure plate 21.

[0042] The cylinder flange 12 can be threadedly connected to the hydraulic cylinder 11 , so that the cylinder flange 12 can be disassembled when needed.

[0043] During assembly, the cylinder flange 12 can be connected to the end of the hydraulic cylinder 11, and then the cylinder flange 12 can be abutted against the pressure plate 21. Then, the pressure plate flange 22 can be installed on the cylinder flange 12 using bolts 23 to achieve axial fixation of the cylinder flange 12. Correspondingly, the cylinder flange 12 can slide radially within the active cavity 201.

[0044] Further, see Figure 4 A guide member 30 is provided on the outer periphery of the pressure plate 21; the guide member 30 is used to guide the pressure plate assembly 20 to align with the barrel 60 after the pressure plate 21 extends into the barrel 60.

[0045] When the pressure plate 21 is pressed into the barrel 60 , the guide member 30 can push the pressure plate 21 to move toward the centering direction, thereby guiding the pressure plate assembly 20 to align with the barrel 60 .

[0046] As an embodiment, the guide member 30 is an elastic wear-resistant belt.

[0047] Specifically, after the guide member 30 is set, the outer diameter of the pressure plate 21 can be set to be equal to the inner diameter of the barrel 60; in the process of pressing the pressure plate 21 into the barrel 60, if there is an offset between the central axis of the pressure plate 21 and the barrel 60, the guide member 30 located on the side of the offset direction of the pressure plate 21 will be squeezed and provide an elastic force to the pressure plate 21 to move in the centering direction, thereby guiding the pressure plate 21 to be centered with the barrel 60.

[0048] Furthermore, a seal 40 is provided on the outer periphery of the pressure plate 21 to prevent material from leaking between the pressure plate 21 and the barrel 60 .

[0049] Furthermore, a frame 50 is included; the hydraulic cylinder assembly 10 is slidably disposed on the frame 50 along the axial direction of the hydraulic cylinder assembly 10 .

[0050] The above are only preferred embodiments of the present application and are not intended to limit the present invention. Although the present application has been described in detail with reference to examples, those skilled in the art can still modify the technical solutions described in the aforementioned examples or make equivalent replacements for some of the technical features therein. However, any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present application should be included in the scope of protection of the present application.
