Problems solved by technology

Using this method to make straw mats can effectively solve the shortcoming that the straw is easy to loosen. However, because the lower die is used to pressurize, at the same time, the one-time molding method must have uneven density on the top and bottom of the straw mats. At the same time, the thickness of the straw mats is relatively thick. It is not easy to compact and other disadvantages, which is a potential hidden danger for the transportation of metal and inorganic plates and strips that are getting heavier and have higher surface requirements
[0005] The purpose of the present invention is to provide a production process of vertical hydraulic straw mats, which can avoid the phenomenon of uneven density at the top and bottom, and can realize the production of thicker grass mats at the same time

Embodiment 1

[0017] Make straw pads with a height of 30mm and a width of 160mm, adjust the height of the mold cavity to 200mm, and a width of 160mm, fill a certain amount of straw into the cavity, and the upper mold is pre-pressed under the action of the hydraulic rod. The compression pressure is 10t, and the holding time is 30s. After the pre-pressing is finished, continue to increase the pressure to 20t, and hold the pressure for 30s for compaction and shaping. After the pressure holding is completed, the movable module moves upwards to the top of the upper mold under the action of hydraulic pressure, and at the same time, the iron wire is bound through the upper and lower mold teeth to bind the straw, the upper mold moves upward, and the straw pad is taken out, and the movable module returns to the original position .

Embodiment 2

[0019] Make straw mats with a height of 100mm and a width of 160mm, adjust the height of the mold cavity to 300mm, and a width of 160mm, fill a certain amount of straw into the cavity, and the upper mold is pre-pressed under the action of the hydraulic rod. The compression pressure is 20t, and the holding time is 60s. After the pre-compression is completed, continue to increase the pressure to 30t, and hold the pressure for 60s for compaction and finalization. After the pressure holding is completed, the movable module moves upwards to the top of the upper mold under the action of hydraulic pressure, and at the same time, the iron wire is bound through the upper and lower mold teeth to bind the straw, the upper mold moves upward, and the straw pad is taken out, and the movable module returns to the original position .

Embodiment 3

[0021] Make straw pads with a height of 150mm and a width of 210mm, adjust the height of the mold cavity to 400mm, and a width of 210mm, fill a certain amount of straw into the cavity, and the upper mold is pre-pressed under the action of the hydraulic rod. The compression pressure is 30t, and the pressure holding time is 90s. After the pre-pressing is over, continue to increase the pressure to 40t, and hold the pressure for 120s for compaction and shaping. After the pressure holding is completed, the movable module moves upwards to the top of the upper mold under the action of hydraulic pressure, and at the same time, the iron wire is bound through the upper and lower mold teeth to bind the straw, the upper mold moves upward, and the straw pad is taken out, and the movable module returns to the original position .

Abstract

The invention relates to a production technique of vertical hydraulic grass pad and is characterized in that the grass pad is made by five steps of padding, pre-pressing, pressurized shaping, iron wire bundling-up and de-molding. The modes of pressurizing upper mold and secondary shaping can effectively solve the problems of non-uniform density of the upper and lower parts of the grass pad, loose compaction of thicker grass pad and the like, thus the grass pad is suitable for supporting large metal and inorganic plate / strip material transportation. The grass pad made by the method has simple technique and equipment, low cost and large use amount.

Description

【Technical field】 [0001] The invention relates to a production process of a vertical hydraulic straw pad, which is especially suitable for supporting and transporting various large steel plates, steel strips, non-ferrous metal steel strips, cement components and stone materials. 【Background technique】 [0002] In recent years, with the rapid development of science and technology, especially the rapid development of the shipbuilding industry, electronics industry and construction industry, users have become more and more demanding on the weight of various gold and inorganic plates and strips, and at the same time have more and more requirements on the surface quality. higher. The use of support pads between layers of materials can effectively avoid contusions during transportation and at the same time facilitate loading and unloading of goods. [0003] At present, there are two main methods of support pads in my country. One is to make support pads by processing high-quality...
