Description

Technical Field

[0001] The utility model relates to the technical field of block forming equipment, in particular to a vibration pressing machine. Background Art

[0002] Concrete blocks are equipment that produce new wall blocks by adding a small amount of cement to materials such as sand, gravel, fly ash, etc. These new concrete blocks have the characteristics of high strength, easy masonry, good wall flatness and fast construction efficiency. Nowadays, concrete block forming equipment mainly includes two methods: vibration forming and hydraulic forming. The blocks produced by hydraulic forming equipment are formed by squeezing the concrete raw materials through the extension and contraction of the hydraulic cylinder. If the hydraulic cylinder cannot provide a large enough pressure, the density and strength of the block products will be insufficient. The core of the vibration forming equipment is the vibration system. The mixture in the mold frame becomes dense due to the exciting force provided by the vibration table, and the amplitude and frequency of the vertical upward vibration of the vibration system are not large, which will also lead to insufficient density and strength of the block products, unstable quality, etc., and the existing concrete block forming equipment needs the cooperation of the distribution device during operation. The distribution device's distribution vehicle enters the equipment to distribute the material to the mold in the equipment. The equipment is generally provided with a distribution vehicle track for the distribution vehicle to travel, and different molds are required when making different blocks. In order to meet the molds of different heights, the height of the distribution vehicle track needs to be adjusted, and the distribution vehicle track of the existing equipment adopts a fixed installation method, and the height adjustment is not easy.

The vibration press of this embodiment adopts the main pressure cylinder assembly and the vibration device 3 to cooperate to perform molding operations, and has high working efficiency and high product quality.

[0028] In this embodiment, a column 401 is installed on the frame 1, and the guide rail 4 is installed on the column 401 through a vertical adjustment mechanism. The vertical adjustment mechanism includes a guide rail mounting plate 403, a clamping plate 405 and an adjusting screw 406 installed on the column 401. The guide rail 4 is installed on the guide rail mounting plate 403 through the clamping plate 405, and the clamping plate 405 is fixed to the guide rail mounting plate 403 by bolts 407. The adjusting screw 406 is vertically positionally adjustable and installed below the clamping plate 405. The upper end of 406 abuts against the clamping plate 405, and the height of the guide rail 4 can be adjusted through the vertical adjustment mechanism, so that the vibration press can adapt to mold frames of different heights. When adjusting the height of the guide rail 4, loosen the bolt 407 on the clamping plate 405, adjust the vertical position of the screw 406, and the height of the guide rail 4 can be adjusted. After adjusting to the right position, tighten the bolt 407. In this embodiment, two guide rails 4 are relatively arranged in the frame 1, and the heights of the two guide rails 4 can be adjusted. Two wear-resistant plates 402 arranged up and down are fixed in each guide rail 4.

[0029] In this embodiment, an adjustment block 409 is fixedly connected to the column 401 below the guide rail mounting plate 403.

When the vibration device 3 is working, the motor 301 drives the transmission shaft 304 and the eccentric block 305 to rotate. The rotation of the eccentric block 305 provides an exciting force for the moving table 302 to achieve vibration.

[0031] In this embodiment, the motor 301 is installed on the base 101 through a motor seat, and the output end of the motor 301 is connected to the transmission shaft 304 through a transmission belt.

Each rack 503 is vertically arranged, and the upper end of each rack 503 is fixedly connected to a sleeve 504, and the upper end of the sleeve 504 is connected to the joint shaft. The bearing 507 is connected to the mold frame fixing seat 6 on the corresponding side, and each of the racks 503 is rollingly matched with a positioning wheel 505, and the positioning wheel 505 is rotatably installed on the base 101. The positioning wheel 505 and the cylindrical gear 502 are arranged on the opposite sides of the rack 503. When the mold frame fixing seat 6 is raised or lowered, the joint bearings 507 and the rack 503 at both ends of the synchronization shaft 501 will be driven to rise or fall, and the rack 503 will drive the corresponding cylindrical gear 502 and the synchronization shaft 501 to rotate, and the synchronization shaft 501 will ensure that the mold frame fixing seats 6 at both ends thereof are raised or lowered synchronously.

[0033] In this embodiment, both ends of each of the synchronous shafts 501 are respectively mounted on the base 101 through square seat bearings 508, and a connecting rod 506 is provided between the two positioning wheels 505 at the same end of the two synchronous shafts 501.

[0034] The main pressure cylinder assembly of the vibrating press of this embodiment adopts a hydraulic cylinder that can provide 1500 tons of pressure, which can ensure the density and strength of the blocks. While providing high pressure to press the mold, the raw materials are vibrated and formed by the vibrating device 3. When the vibrating press is in operation, the material cart loaded with concrete aggregate passes through the guide rail 4 to the upper mold frame of the vibrating device 3 for distribution. After the operation of the vibrating device 3 is completed, the pump plug rod in the main pressure cylinder assembly extends out, driving the upper die assembly 2 to move vertically toward the vibration table 302 system direction, so as to achieve the effect of squeezing the concrete raw materials. Pressure molding and vibration molding are carried out simultaneously, which ensures the work efficiency and the molding quality of the blocks.
