Embodiment 1

[0051] Such as figure 1 , figure 2 As shown, a high-precision automatic pressing device of the present embodiment includes a frame 12, an oil cylinder, a slider 10 and a workbench 11. The oil cylinder is installed on the frame 12, and the slider 10 is hoisted below the oil cylinder and Its two ends are slidably connected with the slide rail 4 of the frame 12 inner test, and the upper die 14 is installed under the above-mentioned slide block 10, and the upper die 14 can move up and down with the slide block 10, and the workbench 11 and the machine The frame 12 is connected together, and the lower die 16 matched with the upper die 14 is installed thereon. The oil cylinder of this embodiment includes a first oil cylinder 301 and a second oil cylinder 302, the first oil cylinder 301 and the second oil cylinder 302 are fixedly connected with the top ends of the slider 10 respectively, and the top of the first oil cylinder 301 is equipped with a first synchronization valve Group ...

Embodiment 2

[0058] Such as Figure 1-Figure 5 As shown, the structure of a high-precision automatic pressing device of this embodiment is the same as that of Embodiment 1.

[0059] The density, thickness and flatness of metal fiber products have a great influence on the filtration performance of the filter element, which directly affects the efficiency and quality of filter filtration, and at the same time has a greater impact on the service life of the filter element. Since the material of the metal fiber product 20 is relatively soft, rheology is prone to occur during the stress process, and it is even more difficult to ensure the uniformity of its thickness during the pressing process. Therefore, how to ensure that the uniformity of the thickness after pressing and the flatness and density of the product surface can meet the requirements of the filter element is a technical difficulty to be overcome by the present invention. In order to effectively ensure that the thickness uniformity...

Abstract

The invention discloses a high-precision automatic material pressing method used for metal fiber products and belongs to the technical field of pressing forming. According to the high-precision automatic material pressing method, a high-precision automatic material pressing device is used for conducting pressing forming on the metal fiber products; a feeding roller mechanism is used for conveying the to-be-pressed metal fiber products in the feeding direction; a numerical control system is used for controlling the feeding roller mechanism, a discharging roller mechanism and a motor oil pump set to work respectively; and therefore the metal fiber products are subjected to multi-time and multi-point moving pressing. The pressing process includes the following steps of reference point finding, feeding, pressing, returning, material moving and discharging. When the technical scheme is adopted for conducting pressing forming on metal fiber, thickness evenness of the finally obtained metal fiber products can be effectively ensured, compactness and flatness of the obtained metal fiber are good, and therefore the use requirement of a filter filtering element can be met.

Description

technical field [0001] The invention belongs to the technical field of pressing and forming, and more specifically relates to a high-precision automatic pressing method for metal fiber products. Background technique [0002] At present, with the development of filters, various filter materials have been used in a wide range of technical fields, such as petrochemical, polyester fiber, iron and steel metallurgy, biomedicine, food and beverage, and thermal power generation. In terms of materials, filter materials can be divided into two categories: inorganic and organic. Among them, inorganic filter materials include metal filter materials and ceramic filter materials, which are mainly used in environments with high temperature resistance, high pressure resistance and strong corrosion. For example, metal membranes or ceramic membranes are used to recover expensive catalysts in the catalytic cracking process of petrochemical industry. However, most of the existing metal filter...
