Description

Technical Field

[0001] The utility model relates to the technical field of vibration presses, in particular to a vibration press. Background Art

[0002] When a traditional vibratory press presses a mineral mixture, the vibratory pressing head is started. The vibratory pressing head is located on the top of the vibratory pressing plate and drives the vibratory pressing plate to move in the vertical direction, so that the vibratory pressing plate can press the mineral mixture multiple times until a product with a dense structure is formed.

[0003] Among them, a limit plate is arranged above the vibration pressing plate. When the vibration pressing plate is in the pressing process, the limit plate can limit the movable range of the vibration pressing plate, so that the vibration pressing plate always presses the mineral mixture in the vacuum frame within a certain space.

[0004] However, the vibration frequency of the vibrating press head is high and the pressing force is large. When the vibrating press is pressing a mineral mixture, the vibrating pressing plate will hit the limit plate at a high frequency for a long time, which can easily cause damage to the vibrating pressing plate and shorten the service life of the vibrating press.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Combine the following Figures 1 to 4 , describing a vibration press according to an embodiment of the utility model.

[0031] A vibration press comprises a vibration platen 1, a vacuum frame 2 and a base 3, wherein the vacuum frame 2 is located on the base 3, the vibration platen 1 is located in the middle of the vacuum frame 3, a plurality of elastic members 4 are provided around the top of the vibration platen 1, and the plurality of elastic members 4 are used to movably press the vibration platen 1 and limit the vibration range of the vibration platen 1 in the vertical direction;

[0032] A receiving cavity is formed between the top of the vibration platen 1 and the vacuum frame 2 , and the receiving cavity is used to store the elastic member 4 .

[0033] In a vibration press of the present scheme, a vibration pressure head is installed above a vibration pressing plate 1. When the vibration pressure head is started, the vibration pressure head can drive the vibration pressing plate 1 to press downward against the mineral mixture in the vacuum frame 2, so that the mineral mixture in the vacuum frame 3 can be pressed into a product with a dense structure.

[0034] The conventional vibration press is provided with a limit plate above the vibration platen 1. When the vibration platen 1 is in the pressing process, the limit plate can limit the range of movement of the vibration platen 1, so that the vibration platen 1 always presses the mineral mixture in the vacuum frame 3 within a certain space. Since the frequency of the vibration press is high and the pressing force is large, when pressing the mineral mixture, the vibration platen 1 hits the limit plate for a long time, which can easily cause damage to the vibration platen 1 and shorten the service life of the vibration press.

[0035] Therefore, in this solution, a receiving space is provided between the vibration platen 1 and the vacuum frame 2, and an elastic member 4 is provided in the receiving space.

[0036] When the vibration platen 1 bounces upward, the top of the elastic member 4 abuts against the vacuum frame 2, and the bottom of the elastic member 4 abuts against the vibration platen 1. At this time, the elastic member 4 can absorb and disperse the impact force brought by the vibration platen 1, thereby protecting the vibration platen 1, thereby solving the problem of the vibration platen 1 colliding with the vacuum frame 2, thereby shortening the service life of the vibration press.

[0037] The elastic member 4 includes a plurality of inflatable air bags spliced ​​to each other, the top of the elastic member 4 abuts against the vacuum frame 2 , and the top of the vibration platen 1 movably presses against the elastic member 4 .

[0038] It is worth noting that the inflatable airbag is generally made of lightweight materials, has the advantages of light weight and small size, and is very suitable for such frequent vibration occasions. Moreover, after the inflatable airbag is deflated due to the impact of the vibrating plate 1 for a long time, its cushioning performance can be restored by re-inflation, so it can be reused, reducing the cost of use.

[0039] A rubber pad 5 is provided between the elastic member 4 and the vibration pressure plate 1 .

[0040] The surface of the rubber pad 5 is relatively soft, which can reduce the elastic member 4 from being scratched during impact, thereby reducing the damage to the elastic member 4, thereby extending the service life of the elastic member 4. In addition, the surface of the rubber pad 5 has a certain degree of roughness, which can increase the friction between the elastic member 4 and the rubber pad 5, thereby ensuring stable contact between them and preventing sliding or displacement during impact.

[0041] A vertical first baffle 11 is installed on the top of the vibration platen 1, and a horizontal second baffle 21 is installed on the top of the vacuum frame 2. The first baffle 11 is vertically connected to the second baffle 21, and the square accommodating cavity is formed between the first baffle 11, the second baffle 21, the vibration platen 1 and the vacuum frame 2;

[0042] The top of the elastic member 4 is fixedly connected to the second baffle 21 , and the bottom of the elastic member 4 is in contact with the vibration pressure plate 1 .

[0043] A first baffle 11 is mounted on the vibration platen 1, and a second baffle 21 is disposed on the vacuum frame 2. At this time, the first baffle 11 and the vibration platen 1 form an L-shaped structure, and the second baffle 21 and the vacuum frame 2 form an inverted L-shaped structure. The above two structures are assembled to form a complete, square accommodating cavity that can accommodate the elastic member 4. The elastic member 4 is located in the accommodating cavity, which can limit the position of the elastic member 4 and prevent the elastic member from being offset in multiple collisions.

[0044] The inflatable airbag is elliptical in shape.

[0045] The elliptical inflatable airbag can ensure that the pressing force applied by the vibration pressure plate 1 to the elastic member 4 during the movement can be evenly distributed on the entire surface of the airbag, which helps to prevent excessive stress concentration at certain points, thereby extending the service life of the inflatable airbag.

[0046] A sealing strip 6 is provided between the side wall of the vibration platen 1 and the side wall of the vacuum frame 2 , and the sealing strip 6 is used to prevent air from entering the vacuum frame 2 .

[0047] The sealing strip 6 is vertically installed in the gap between the vibration platen 1 and the vacuum frame 2, so that the two side walls of the sealing strip 6 are tightly fitted with the side walls of the vibration platen 1 and the vacuum frame 2 respectively, which can effectively limit the movable position of the vibration platen 1, so that the vibration platen 1 always moves in the original place during the pressing process, which can not only prevent the vibration platen 1 from position displacement, resulting in collision and damage between the vibration plate and the vacuum frame 2, but also improve the sealing effect of the vacuum frame 2 to prevent air from entering the vacuum frame 2.

[0048] The sealing strip 6 comprises a main body 61, and one side of the main body 61 is provided with an inclined first inclined portion 62 and a second inclined portion 63 in sequence from top to bottom;

[0049] A first abutting surface 64 is disposed on a side of the first inclined portion 62 away from the main body 61 , and a second abutting surface 65 is disposed on a side of the second inclined portion 63 away from the main body 61 .

[0050] The sealing strip 6 is installed in the gap between the vibration platen 1 and the vacuum frame 2, wherein the side wall of the main body 61 away from the first inclined portion 62 is tightly fitted with the side wall of the vibration platen 1, and the first abutting surface 64 and the second abutting surface 65 are respectively abutted against the side wall of the vacuum frame 2, which can limit the active position of the vibration platen 1 and prevent the vibration platen 1 from being displaced.

[0051] Since the first inclined portion 62 is installed at the top of one side of the main body 61, the staff can adjust the inclination angle of the first inclined portion 62 so that the first abutting surface 64 on the first inclined portion 62 can fit tightly with the vacuum frame 2. The second inclined portion 63 is installed at the bottom of the main body 61 on the side close to the first inclined portion 62. At this time, the staff can adjust the inclination angle of the second inclined portion 63 so that the second abutting surface 65 of the second inclined portion 63 can fit tightly with the vacuum frame 2.

[0052] The main body 61 , the first inclined portion 62 and the second inclined portion 63 are an integrally formed structure.

[0053] The one-piece molding process can effectively reduce the number of assembly steps and potential connection problems, thereby improving the structural strength of the sealing strip 6 and effectively reducing the occurrence of the first inclined portion 62 and the second inclined portion 63 being separated from the main body 61 .

[0054] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementation methods of the present invention without creative work, and these methods will fall within the protection scope of the present invention.
