Description

Technical Field

[0001] This utility model relates to the field of refractory material preform production technology, and in particular to a vibration preparation device for refractory material preforms. Background Technology

[0002] Refractory materials are a class of inorganic non-metallic materials with a refractoriness of not less than 1580℃. Refractoriness refers to the Celsius temperature at which a conical specimen of a refractory material can resist high temperature without softening or melting under no load. However, the definition of refractoriness alone cannot fully describe refractory materials. 1580℃ is not absolute. It is now defined as any material whose physical and chemical properties allow it to be used in high-temperature environments. Refractory materials are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields, with the largest usage in the metallurgical industry.

[0003] Currently, in the production process of refractory preforms, vibration is required to make the refractory preforms more compact in the mold. The common vibration preparation device is a device consisting of a vibration motor, a base and a vibration platform.

[0004] However, the above-mentioned vibration preparation device only uses a single vibration motor to generate vibration for preparation, and the vibration intensity is generally not good enough to meet the application requirements. Therefore, we propose a vibration preparation device for refractory preforms. Utility Model Content

[0005] The purpose of this invention is to provide a vibration preparation device for refractory preforms. Through this vibration mechanism, the first vibration component can be used to make the vibration platform vibrate up and down, and the second vibration component can be used to make the vibration platform vibrate left and right, thereby making the vibration platform produce a better vibration intensity on the preform mold.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] This utility model provides, for example Figures 1-4The diagram shows a vibration preparation device for refractory preforms.

[0036] Example 1: Includes a base 1, on which a vibration mechanism is mounted. The vibration mechanism includes a vibration platform 2, which is located on top of the base 1. A precast mold 4 is placed on top of the vibration platform 2. A clamping assembly 3 is mounted on the vibration platform 2 to clamp and fix the precast mold 4. A positioning assembly 6 is located between the base 1 and the vibration platform 2. A first vibration assembly 5 is located at the bottom of the positioning assembly 6 and is used to drive the positioning assembly 6 to vibrate. A second vibration assembly 7 is located on the side of the positioning assembly 6 and is used to strike the positioning assembly 6. By vibrating the precast mold 4... The preform mold 4 is placed on the vibration platform 2 and then fixed by the clamping assembly 3. Subsequently, the first vibration assembly 5 drives the vibration platform 2 and the preform mold 4 to vibrate up and down, while the second vibration assembly 7 continuously strikes the positioning assembly 6, thereby causing the vibration platform 2 and the preform mold 4 to be vibrated left and right by the striking. This design utilizes up and down vibration and left and right striking vibration to enable the vibration platform 2 to produce a good vibration effect, thereby producing a good vibration intensity on the preform mold 4. The preform mold 4 is used to produce preforms of wear-resistant materials. The specific production method is existing technology and will not be described in detail here.

[0037] Furthermore, the second vibration component 7 includes a fixed shaft 701, which is fixedly connected to the inside of the base 1. A rotating sleeve 702 is rotatably connected to the outside of the fixed shaft 701. A pressure rod 703 is fixedly connected to one side of the bottom of the rotating sleeve 702. A connecting rod 704 is fixedly connected to one side of the top of the rotating sleeve 702. A striking block 705 is fixedly connected to one end of the connecting rod 704. A gear 706 is rotatably disposed below the rotating sleeve 702. As the gear 706 rotates, the teeth of the gear 706 continuously push against the pressure rod 703, causing one end of the pressure rod 703 to tilt upwards. This causes the rotating sleeve 702 to rotate, thereby causing the connecting rod 704 and its striking block 705 to tilt upwards. When the teeth of the gear 706 no longer push against the pressure rod 703, the striking block 705 falls freely, thereby striking the positioning component 6, which in turn causes left and right striking of the vibration platform 2.

[0038] Furthermore, the positioning component 6 includes a positioning post 601 fixedly connected to the bottom of the vibration platform 2, a buffer spring 602 sleeved on the outer surface of the positioning post 601, and a connecting plate 603 fixedly connected to the positioning post 601 through one end of the top of the base 1. When the first vibration component 5 drives the connecting plate 603 to move upward, it drives the positioning post 601 and its vibration platform 2 to move upward. When the first vibration component 5 stops pushing the connecting plate 603, the vibration platform 2 and its connecting plate 603 fall freely, and the buffer spring 602 buffers the impact force of the fall.

[0039] Furthermore, the first vibration assembly 5 includes a pressure plate 505, which is fixedly connected to the bottom of the connecting plate 603. Both sides of the bottom of the base 1 are rotatably connected to a first rotating shaft 502, and a rotating cylinder 503 is fixedly connected between the two first rotating shafts 502. One end of one of the first rotating shafts 502 is fixedly connected to a first motor 501, and multiple top blocks 504 are fixedly connected to the outer surface of the rotating cylinder 503. When the first motor 501 rotates, it drives the first rotating shaft 502 to rotate, which in turn drives the rotating cylinder 503 to rotate, thereby driving the top blocks 504 to rotate. This causes the top blocks 504 to push against the pressure plate 505, causing the connecting plate 603 and its vibration platform 2 to move upward. When the top blocks 504 no longer press against the pressure plate 505, the connecting plate 603 falls freely. With the continuous rotation of the rotating cylinder 503, the vibration platform 2 moves up and down continuously, thereby generating up-and-down vibration.

[0040] Furthermore, multiple top blocks 504 are arranged in a circular array with the center of the rotating cylinder 503 as the array center, and the cross-sectional profile of the top blocks 504 is set as triangular, so that the triangular top blocks 504 can better push the pressure plate 505, thereby driving the connecting plate 603 to move upward.

[0041] Furthermore, the length of the pressure rod 703 is smaller than that of the connecting rod 704. A second rotating shaft is fixedly connected to the middle of the gear 706. The second rotating shaft is rotatably mounted on the inner wall of the base 1. A second motor is fixedly connected to one end of the second rotating shaft. The second rotating shaft is driven to rotate by the second motor, thereby driving the gear 706 to rotate.

[0042] Furthermore, the number of positioning components 6 is set to four, and the four positioning components 6 are respectively located at the four corners of the vibration platform 2, and each buffer spring 602 is located at the top of the base 1; so that the vibration platform 2 can fall and compress the buffer spring 602 better.

[0043] Example 2: Example 2 further discloses, based on Example 1, that the clamping assembly 3 includes a groove, which is opened in the middle of the vibration platform 2. A clamping threaded rod 301 is rotatably connected inside the groove. A moving block 302 is threadedly connected to the outer surface of the clamping threaded rod 301. A clamping plate 303 is fixedly connected to the top of the moving block 302. By rotating the handwheel fixedly connected to the clamping threaded rod 301, the clamping threaded rod 301 is rotated. Due to the limitation between the moving block 302 and the groove, the moving block 302 will not rotate. The rotating clamping threaded rod 301 drives the moving block 302 to slide along the groove, thereby driving the clamping plate 303 to clamp and fix the precast mold 4. The clamping threaded rod 301 is a double-ended threaded rod, which drives the two clamping plates 303 to move closer or further apart.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
