Description

Technical Field

[0001] This utility model relates to the field of vibration molding technology, and in particular to a vibration molding machine with a separate bearing and guiding structure and a vibration molding machine. Background Technology

[0002] A vibration molding machine is a large-scale processing equipment, especially used in the processing of carbon products. A mixed paste is added to the mold box of the vibration molding machine, and the carbon paste is shaped by the vibration of the vibration platform. To ensure product quality, it is necessary to expel as much gas as possible from the paste. This is achieved by installing a vacuum hood above the mold box to ensure its relative airtightness, and by drawing a vacuum to expel the gas from the paste inside the mold box.

[0003] For related technology, please refer to Chinese Patent No. CN111469480B, which discloses a four-column guided vacuum pressure vibration molding machine, including a frame with four columns. The bottom of the columns is fixedly installed on a base, and a top mounting seat is fixedly installed on the top of the columns. A counterweight beam is installed between the top mounting seat and the base. The counterweight beam is slidably installed on the columns. A connecting column is fixedly installed below the counterweight beam. A vacuum hood is fitted onto the connecting column. A pressure head is fixedly installed at the bottom of the connecting column. A vibration platform is installed on the base, and a mold box is installed on the vibration platform. The mold box is located below the pressure head, and locking mechanisms are installed on both sides of the mold box on the vibration platform.

[0004] In the aforementioned technologies, the four conventional columns serve both as guides and positionsers for the counterweight beam and as supports for the entire machine. As the core support structure, they ensure the stability of the equipment during operation and prevent displacement or tilting during vibration. During vibration molding, the four columns provide precise guidance for the counterweight beam, ensuring that the beam, driving the pressure head, applies pressure smoothly to the material during vibration, thus guaranteeing molding quality. As the core support structure, the columns require enhanced rigidity and stability, resulting in an increased material cross-section. When the columns function as guides, their surfaces must be wear-resistant and smooth, requiring surface hardening and precision machining.

[0005] Given the dual function of the four columns, it is necessary to increase their diameter during processing to ensure support strength, and materials with sufficient strength and hardness must be used. This is especially true for larger vibration molding machines, where both the length and diameter of the columns need to be increased. However, as the length and diameter of the columns increase, the costs of materials, processing, transportation, and on-site installation will also rise accordingly.

[0006] Based on this, the present invention provides a vibration molding machine with a separate bearing and guiding structure and a vibration molding machine. Utility Model Content

[0007] This utility model addresses the shortcomings of existing technologies by providing a vibration molding machine with a separate load-bearing and guiding structure, and a vibration molding machine in general.

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0009] In the first aspect, this utility model discloses a vibration molding machine with a separate bearing and guiding structure.

[0010] A vibration molding machine with a separate load-bearing and guiding structure includes a lower base, an upper beam frame, and a support structure. The support structure includes a first support part and a second support part, the tops of which are connected to the upper beam frame, and the bottom ends of which are connected to the lower base. The first support part includes a first pillar and a second pillar, and the second support part includes a third pillar and a fourth pillar. It also includes guide columns located between the first and second pillars, and between the third and fourth pillars. The bottom end of the guide column is connected to the lower base, and the guide column is connected to the upper beam frame. The upper beam frame includes a rectangular frame structure composed of four beams.

[0011] The technical effect of adopting the above technical solution is as follows: the supporting structure provides support, ensuring the stability of the equipment during operation and preventing displacement or tilting during vibration. Specifically, it includes a symmetrically arranged first and second supporting parts. Guide columns are provided between the first and second columns, and between the third and fourth columns. The guide columns are used to guide the up and down sliding of the counterweight beam. Compared with the traditional four-guide column structure, the main function of the guide columns in this utility model is not to provide support, but only to provide guidance for the counterweight beam. Therefore, the strength of the guide columns can be reduced to meet the strength requirements for guiding the counterweight beam. That is, when not providing support and only providing positioning guidance, the diameter of the guide columns can be reduced, and the strength of the guide columns can also be reduced accordingly, so as to save on the cost of materials, processing, transportation, and on-site installation of the columns.

[0012] Furthermore, two guide columns are provided between the first and second pillars, and two guide columns are provided between the third and fourth pillars, to improve the stability of the counterweight beam when it slides.

[0013] Furthermore, the materials for the first, second, third, and fourth pillars are all structural steel profiles, that is, structural steel profiles that meet strength requirements and are inexpensive, such as I-beams, channel steel, or steel pipes.

[0014] Furthermore, the guide column is made of alloy structural steel.

[0015] Secondly, this utility model also discloses a vibration molding machine.

[0016] A vibration molding machine includes the above-described vibration molding machine bearing and guiding separate whole machine structure, and also includes a counterweight beam. The counterweight beam is located between the first support part and the second support part, and the two sides of the counterweight beam are respectively slidably connected to the guide column. The upper beam is equipped with a lifting mechanism connected to the counterweight beam, and the lower machine base is equipped with a vibration platform.

[0017] The technical effect of adopting the above technical solution is as follows: The vibration molding machine includes the aforementioned support structure, which provides reliable support for the entire vibration molding machine. The counterweight beam is slidably connected to the guide column, and the up-and-down sliding of the counterweight beam is driven by a lifting mechanism. The lifting mechanism is mounted on the upper beam frame, which provides support for the lifting mechanism. Therefore, although the counterweight beam slides on the guide column, the overall weight of the counterweight beam is supported by the lifting mechanism. The guide column only provides guidance to facilitate the sliding of the counterweight beam. Thus, the strength and diameter of the guide column can be reduced compared to existing technologies, while still meeting the strength requirements of the guide column. In other words, by reducing the strength and diameter of the guide column in this utility model, material, production, transportation, and on-site installation costs can be reduced.

[0018] Furthermore, guide sleeves are provided on both sides of the counterweight beam, the guide column passes through the guide sleeve, and the guide sleeve is slidably connected to the guide column.

[0019] The technical effect of adopting the above-mentioned further technical solution is that the guide column penetrates the guide sleeve, making the ballast beam slide more conveniently and smoothly.

[0020] Furthermore, the guide sleeve corresponds one-to-one with the guide post.

[0021] Furthermore, the lifting mechanism is a hydraulic cylinder, the piston rod of the hydraulic cylinder is connected to the counterweight beam, and the hydraulic cylinder is connected to the upper beam frame. Attached Figure Description

Detailed Implementation

[0026] The principles and features of this utility model are described below with reference to all the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0027] This utility model discloses a vibration molding machine with a separate load-bearing and guiding structure and vibration performance.

[0028] Example 1

[0029] Reference Figure 1 and Figure 2 This utility model embodiment provides a vibration molding machine with a separate bearing and guiding structure, including a lower base 24, an upper beam frame 23, guide columns 3, and a support structure 2. The support structure 2 is a welded profile component used to provide support, ensure the stability of the equipment during operation, and prevent displacement or tilting during vibration. The support structure 2 includes a first support part 21 and a second support part 22. The tops of the first support part 21 and the second support part 22 are both connected to the upper beam frame 23, and the bottoms of the first support part 21 and the second support part 22 are both connected to the lower base 24.

[0030] The first support part 21 and the second support part 22 have the same structure. The first support part 21 and the second support part 22 are located on both sides of the upper beam frame 23 and are symmetrically arranged. In this embodiment, the first support part 21 is mainly used as an example for explanation.

[0031] The first support part 21 includes a first pillar 211 and a second pillar 212, and the second support part 22 includes a third pillar 221 and a fourth pillar 222. The top ends of the first pillar 211, the second pillar 212, the third pillar 221 and the fourth pillar 222 are fixedly connected to the lower side of the upper beam frame 23, and the bottom ends of the first pillar 211, the second pillar 212, the third pillar 221 and the fourth pillar 222 are fixedly connected to the upper side of the lower base 24 to improve the support stability of the entire support structure 2. Two sets of guide columns 3 are provided, one set is provided between the first pillar 211 and the second pillar 212, and the other set is provided between the third pillar 221 and the fourth pillar 222.

[0032] The guide column 3 is used to guide the up and down sliding of the counterweight beam 4. The bottom end of the guide column 3 is connected to the lower base 24, and the top end of the guide column 3 extends upward to the lower side of the upper beam frame 23 and is connected to the upper beam frame 23.

[0033] Compared to the traditional four-column structure, the main function of the guide column 3 in this embodiment is not to provide support, but to guide. That is, the guide column 3 is used to guide the up and down sliding of the counterweight beam 4. When the guide column 3 plays a guiding role rather than a supporting role, the strength and diameter of the guide column 3 can be shortened accordingly (compared to the traditional four-column structure), thereby achieving the purpose of saving costs.

[0034] Specifically, traditional four-guide-post structures serve both guiding and positioning functions as well as providing fixed support. Therefore, the four guide posts have large diameters and long lengths, resulting in high costs for materials, processing, transportation, and on-site installation. In this structure, the support structure 2 provides fixed support, while the four guide posts 3 primarily serve guiding and positioning functions. The diameter of the guide posts 3 is reduced to two-thirds of the original, significantly lowering material and processing costs. Simultaneously, the first support section 21 and the second support section 22, which provide support, can be manufactured using structural steel profiles, further reducing material, manufacturing, transportation, and on-site installation costs. Therefore, compared to traditional four-guide-post structures, this solution offers substantial cost savings.

[0035] Two guide columns 3 are provided on each side, and four guide columns 3 are provided in this embodiment of the invention. They are symmetrically arranged in pairs between the first support column 211 and the second support column 212, and between the third support column 221 and the fourth support column 222. That is, two guide columns 3 are provided between the first support column 211 and the second support column 212, and two guide columns 3 are also provided between the third support column 221 and the fourth support column 222. When the counterweight beam 4 slides on the guide columns 3, the stability of the counterweight beam 4 during sliding can be further improved. In this embodiment of the invention, when the guide columns 3 are connected to the upper beam frame 23 and the lower machine base 24, they can be connected by flanges to improve the stability of the guide columns 3.

[0036] Taking a vibration molding machine for producing carbon anode blocks with dimensions of 1900mm in length, 1010mm in width, and 700mm in height as an example, the existing four-column guide and four-column support structure has a guide column 3 with a length of 7600mm and a diameter of Φ350mm, requiring a material of 35CrMo. The guide column 3 as a whole must meet high requirements for surface roughness and support strength. However, with the technical solution of this utility model, the guide column 3 has a diameter of Φ230mm while maintaining the same length. This guide column 3 not only saves a lot of material compared to the original material, but also has lower requirements for processing equipment, greatly reducing processing costs. Furthermore, the support column material used is structural steel profiles, whether it is I-beams, channel steel, or steel pipes. Not only are the requirements for material and surface roughness low, but the materials can also be purchased, cut, manufactured, and installed on-site, greatly saving material, manufacturing, transportation, and on-site installation costs.

[0037] Example 2

[0038] Reference Figure 3 This utility model embodiment also provides a vibration molding machine, including the aforementioned vibration molding machine with a separate bearing and guiding structure. The supporting structure 2 in the overall structure provides support. The vibration molding machine also includes a counterweight beam 4, located between the first support part 21 and the second support part 22. Both sides of the counterweight beam 4 are slidably connected to guide columns 3. The upper beam frame 23 is equipped with a lifting mechanism 1 connected to the counterweight beam 4. The overall weight of the counterweight beam 4 is supported by the lifting mechanism 1, and the sliding of the counterweight beam 4 is driven by the lifting mechanism 1. The lifting mechanism 1 is mounted on the upper beam frame 23, which provides support for the lifting mechanism 1. The lower machine base 24 is equipped with a vibration platform 7 and a mold box 6 mounted on the vibration platform 7. In this utility model embodiment, the upper and lower ends of the guide columns 3 are connected to the upper beam frame 23 and the lower machine base 24, respectively.

[0039] The guide column 3 only serves to guide the movement of the counterweight beam 4. The entire machine structure, consisting of the lower base 24, upper beam frame 23, and support structure 2, bears the load. Therefore, compared with existing technologies, the size (such as diameter) of the guide column 3 can be significantly reduced. Thus, compared with existing four-guide-column technology, the technology of this utility model can significantly reduce material, manufacturing, transportation, and on-site installation costs.

[0040] The lifting mechanism 1 is a hydraulic cylinder. The piston rod of the hydraulic cylinder is connected to the counterweight beam 4, and the cylinder body is connected to the upper beam frame 23. The vertical sliding of the counterweight beam 4 is controlled by the extension and retraction of the piston rod. In this embodiment, a flexible adjustable constant pressure mechanism can also be installed above the counterweight beam 4. This mechanism is not described in detail in this embodiment, but can be found in the published patent CN111469480B.

[0041] The two sides of the counterweight beam 4 are respectively provided with guide sleeves 5. The number and position of the guide sleeves 5 correspond one-to-one with those of the guide posts 3. The guide posts 3 pass through the guide sleeves 5, and the guide sleeves 5 are slidably connected to the guide posts 3. Lubricant can be added to the guide sleeves 5 to make the guide sleeves 5 slide more conveniently and smoothly.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
