[0033] Combine the following Figures 1 to 4, describing a vibration press for improving the quality of pressed materials in an embodiment of the utility model.

[0034] A vibration press for improving the quality of pressed materials, comprising a vibration base 1, a vacuum frame 2, a vibration pressing head 3, a frame 4 and a vacuum device 5;

[0035] The vibration base 1 is installed on the frame 4, the vacuum frame 2 is located at the upper part of the vibration base 1, the vibration pressure head 3 is located in the middle of the vacuum frame 2, and multiple input ends of the vacuum equipment 5 are respectively connected to the upper part and the lower part of the vacuum frame 2, and the vacuum equipment 5 is used to extract the gas in the vacuum frame 2;

[0036] A sealing strip 6 is provided between the vibration pressure head 3 and the frame 4 , and the sealing strip 6 is used to seal the vacuum frame 2 .

[0037] In the present scheme, a vibration press machine for improving the quality of pressing materials is provided. The vibration pressing head 3 vibrates in the vertical direction, and can repeatedly press the powder in the vacuum frame 2, so that the powder can be turned into a dense product. The sealing strip 6 is installed in the gap between the vibration pressing head 3 and the frame 4, so that the two side walls of the sealing strip 6 are closely fitted with the side walls of the vibration pressing head 3 and the frame 4, respectively, and the movable position of the vacuum frame 2 can be limited, so that the vacuum frame 2 can always move on the original place during the pressing process, which can not only prevent the vibration pressing plate from hitting the frame, but also prevent the vacuum frame 2 from being offset, resulting in uneven force on the product, and defects such as burrs and cracks may appear on the edges.

[0038] In addition, a vacuum device 5 is provided in the vacuum frame 2, and the vacuum device 5 can extract the gas in the vacuum frame 2 at all times, so as to make the powder more compact, increase the density and hardness of the powder, improve the durability and life of the product, and further improve the quality of the pressed material.

[0039] At this time, the sealing strip 6 can also seal the gap between the vibration pressing head 3 and the frame 3, reducing the flow of air and dust into the vacuum frame 2 from the gap, thereby affecting the quality of the pressed material, and ensuring that the vacuum frame 2 is always in a sealed state during the pressing process.

[0040] This solution can prepare a dense product through the combined effect of the vacuum device 5 and the sealing strip 6, improve the quality of the pressed material, solve the problem of the poor quality of the product pressed by the traditional vibration press, and reduce the problem of the vibration press head hitting the frame.

[0041] The vacuum equipment 5 includes a vacuum pump, a first vacuum pumping pipe 52 and a second vacuum pumping pipe 53, wherein the input end of the first vacuum pumping pipe 52 is located at the upper part of the vacuum frame 2, the output end of the first vacuum pumping pipe 52 is connected to the vacuum pump, the input end of the second vacuum pumping pipe 53 is connected to the vibration base 1, and the output end of the second vacuum pumping pipe 53 is connected to the vacuum pump.

[0042] The second vacuum pipe 53 can extract the gas at the bottom of the vacuum frame 2, and the first vacuum pipe 52 can extract the gas at the top of the vacuum frame 2. At this time, the first vacuum pipe 52 and the second vacuum pipe 53 cooperate with each other to effectively discharge a large amount of gas in the vacuum frame 2, making the product pressed by the vibration press more compact and improving the quality of the pressed material.

[0043] There are four first vacuum pipes 52, and the four first vacuum pipes 52 are arranged in a circle on the upper part of the vacuum frame 2;

[0044] There are four second vacuum pipes 53 , and the four second vacuum pipes 53 are arranged around the vibration base 1 .

[0045] In order to better extract the gas in the vacuum frame 2, multiple first vacuum pipes 52 and second vacuum pipes 53 can be set, and the multiple first vacuum pipes 52 and multiple second vacuum pipes 53 are all arranged in a circle in the vacuum frame 2, so as to further improve the efficiency of the vacuum equipment 5 in extracting gas and further improve the quality of the pressed material.

[0046] The sealing strip 6 includes 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 from top to bottom in sequence, and the main body 61, the first inclined portion 62 and the second inclined portion 63 are integrally formed;

[0047] 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 .

[0048] The sealing strip 6 is installed in the gap between the vibration pressure head 3 and the frame 4, wherein the side wall of the main body 61 away from the first inclined portion 62 is tightly fitted with the vacuum frame 2, and the first abutting surface 64 and the second abutting surface 65 are respectively abutted with the frame 4, which can limit the movable position of the vacuum frame 2 and prevent the vacuum frame 2 from being displaced.

[0049] Since the first inclined portion 62 is installed at the upper part 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 frame 4. The second inclined portion 63 is installed at the bottom of the main body 61 near 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 frame 4.

[0050] The first inclined portion 62 and the second inclined portion 63 cooperate with each other, which can not only easily install the sealing strip 6 between the vibration pressure head 3 and the frame 4, but also make the sealing strip 6 tightly connect the vibration pressure head 3 and the frame 4 to prevent the vibration pressure head 3 from being displaced.

[0051] In addition, the first inclined portion 62 and the main body 61 form a Y-shaped structure. When the vacuum pipe on the vibration pressure head 3 is started, the Y-shaped structure can achieve a better sealing effect, preventing external gas and dust from entering the vacuum frame 2 through the gap between the vibration pressure head 3 and the frame 4, thereby further improving the sealing effect of the vacuum frame 2.

[0052] The second inclined portion 63 and the main body 611 also form a Y-shaped structure. When the vacuum pipe on the vibration base 1 is started, the second inclined portion 63 tilts outward and presses against the frame 4, so that the Y-shaped structure can have a better sealing effect, further ensuring the sealing effect inside the vacuum frame 2.

[0053] The inclination angle a between the first inclined portion 62 and the main body 61 is 25-35°;

[0054] An inclination angle b between the second inclined portion 63 and the main body 61 is 25-35°.

[0055] When there is a slight unevenness or gap between the sealing strip 6 and the frame 4, the first inclined portion 62 and the second inclined portion 63 inclined outward can better fill these unevenness or gaps, thereby improving the sealing effect of the sealing strip 6. This solution limits the inclination angles of the first inclined portion 62 and the second inclined portion 63, which can further improve the sealing performance of the sealing strip 6, so that the sealing strip 6 can maintain good sealing performance in various use environments.

[0056] The main body 61 is provided with a plurality of process holes 66 , and the process holes 66 horizontally penetrate the left and right sides of the main body 61 .

[0057] The process hole 66 can effectively remove the gas and cutting slag generated during the processing of the sealing strip 6 , prevent the gas and cutting slag from damaging the sealing strip 6 , and improve the processing quality and efficiency of the sealing strip 6 .

[0058] Moreover, the process holes 66 can reduce the weight of the sealing strip 6 and save material costs while ensuring the strength and rigidity of the sealing strip 6 .

[0059] A groove 67 with an opening direction horizontally facing outward is provided on one side of the main body 61 away from the first inclined portion 62 . The groove 67 horizontally runs through the left and right sides of the main body 61 , and the sidewall of the groove 67 is inclined from outside to inside.

[0060] When the staff needs to remove the sealing strip 6 , they can extend the long rod into the groove 67 and then move the long rod up and down to separate the main body 61 from the vibration pressure head 3 , thereby quickly removing the sealing strip 6 .

[0061] The sealing strip 6 is made of silicone rubber material.

[0062] It is worth noting that silicone rubber materials have high high-temperature stability. Even in a high-temperature environment above 200°C, silicone rubber materials can still maintain a certain flexibility, resilience and surface hardness, and there is no obvious change in mechanical properties.

[0063] The upper end of the main body 61 is narrower than the lower end.

[0064] It is worth noting that the upper end of the main body 61 is narrower, which can reduce the resistance of the sealing strip 6 when it is inserted into the gap between the vibration pressure head 3 and the frame 4, making it easier to insert. The lower end of the main body 61 is wider, which can provide a better sealing effect.

[0065] The vibration base 1 is provided with a plurality of air extraction holes and air extraction pipes, the input end of the air extraction pipe is respectively connected with the plurality of air extraction holes, and the output end of the air extraction pipe is connected with the second vacuum extraction pipe 52. The air extraction holes and air extraction pipes are provided at the bottom of the vibration pressing plate 1, so that the conveying belt on the vibration pressing plate 1 is closely attached to the vacuum pressing plate 1, preventing the conveying belt from arching upward, and further improving the quality of the pressed material.

[0066] 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.
