Description

TECHNICAL FIELD

[0001] The utility model relates to water cutting equipment technical field especially relates to a kind of protective cover of superhigh pressure sand water cutting device. BACKGROUND

[0002] In the field of superhigh pressure sand water cutting technology, using superhigh pressure water flow mixed abrasive (usually sand) to cut various materials is a common industrial processing method. This technology is widely used in metal processing cutting field due to its high efficiency and ability to accurately cut various hard materials. However, the high pressure water flow sprayed by the superhigh pressure water gun nozzle has a pressure of more than 420 MPa, which causes mud and sand to splash and noise during the water cutting process. At the same time, the high-speed water flow and sand released during the cutting process may pose a safety risk to the operator.

[0003] To solve these problems, the utility model provides a kind of protective cover of superhigh pressure sand water cutting device. It aims to form a semi-closed protective space around the cutting area to prevent water and sand from splashing, reduce noise pollution and protect the safety of the operator. The protective cover is usually made of impact-resistant and wear-resistant transparent materials such as reinforced glass or high-strength plastic. However, the cost of transparent materials is relatively high, and the sand carried by the superhigh pressure water flow can scratch the inner wall of the transparent material. The splashing mud and sand can also greatly affect the visibility of the transparent material. Therefore, a more economical stainless steel protective cover is used, and a semi-closed installation method is used to meet the real-time monitoring of the processing process. The purpose of the invention or utility model, design.

[0015] A protective cover for an ultra-high pressure waterjet cutting device includes a cutting machine main unit, a protective cover support, a double-leaf push-pull protective plate, an arc-shaped protective cover, a slide rail, and a semi-enclosed inverted U-shaped protective cover. The protective cover support is installed on the working surface of the cutting machine main unit. A slide rail for the protective plate is provided on the side of the support facing the cutting machine's operating surface and is bolted to the support. The double-leaf push-pull protective plate is embedded in the slide rail, allowing for double-sided opening and closing, facilitating installation and maintenance. The arc-shaped protective cover is a stainless steel arc-shaped protective plate, bolted to both sides of the protective cover support and the upper part of the double-leaf push-pull protective plate, used to isolate the waterjet cutting process. The system mitigates mud splashing and noise, ensuring safety at the production site. A semi-enclosed inverted U-shaped protective cover is bolted to the cover support. Data collection revealed that mud splashing was most severe on the operating surface; therefore, an inverted U-shaped protective cover, at the same height as the double-leaf push-pull protective plate and the arc-shaped protective cover, is installed on the back side of the operating surface. Both the arc-shaped and semi-enclosed inverted U-shaped protective covers are made of stainless steel and bolted to the cover support, enabling efficient maintenance and replacement. The semi-enclosed arrangement of the covers effectively saves on costs and facilitates equipment maintenance.
