Description

Technical Field

[0001] This utility model relates to the field of magnesium alloy casting, specifically to a quantitative tube calibration device for magnesium alloy casting. Background Technology

[0002] Magnesium alloys, as the most environmentally friendly lightweight material currently available, have always attracted much attention and are widely used in aerospace, electronics and communications, biomedicine, and the automotive industry. However, this development also generates a large amount of waste magnesium. The market can achieve recycling through waste magnesium remelting processes. In the waste magnesium alloy recycling and remelting process, a casting metering tube is needed to transfer molten magnesium into a mold for cooling and shaping. Currently, the metering tubes used in the market consist of an inlet tube and a return tube, not a single straight tube. When high-temperature molten magnesium alloy flows continuously into the casting metering tube, it is prone to deformation and bending, forming an "arch" shape. On the one hand, slag blockage can easily occur at the deformed and bent locations of the metering tube, requiring workers to clear the blockage and reduce production efficiency; on the other hand, deformed and bent metering tubes are basically unusable and must be scrapped, increasing production costs. In the current production process, workers use hammering to correct the "arch bridge" shaped casting metering tubes. However, manual operation cannot accurately control the force, resulting in poor uniformity of the metering tubes. This method leads to increased bending of the metering tubes, as well as increased slag blockage and scrap rates, reducing production efficiency and increasing usage costs. Utility Model Content

[0003] The purpose of this invention is to provide a calibration device for a quantitative tube used in magnesium alloy casting. This device solves the problem that existing quantitative tubes for magnesium alloy casting are prone to deformation and develop an "arch" shape after prolonged use. Currently, they can only be calibrated by manual tapping. However, manual calibration cannot accurately control the force, resulting in poor uniformity of the quantitative tube. This method also increases the degree of bending of the quantitative tube, as well as the slag blockage rate and scrap rate.

[0004] To achieve the above objectives, this utility model provides a quantitative tube calibration device for magnesium alloy casting, characterized in that the quantitative tube calibration device for magnesium alloy casting includes a frame, a platform is formed in the frame, fastening components are respectively provided at both ends of the platform, a hydraulic component is provided at the upper end of the frame, the hydraulic component includes a pressure plate, and an arc-shaped groove is formed on the lower surface of the pressure plate, so that the pressure plate can be displaced in the vertical direction;

[0005] Platform grooves are formed at both ends of the platform;

[0006] The fastening assembly includes a fastening strip hinged to the platform, the fastening strip having a fastening groove that mates with a groove in the platform;

[0007] This allows the two ends of the metering tube to engage between the platform groove and the fastening groove.

[0008] Preferably, the platform is provided with a rotating seat, one end of the fastening strip is hinged to the rotating seat, and the other end is provided with an anti-slip handle.

[0009] Preferably, a fixed seat is provided in the platform away from the rotating seat, and a first pin hole is formed on the fixed seat; a second pin hole is provided in the fastening strip near the anti-slip handle, and the pin passes through the first pin hole and the second pin hole.

Fastening components are respectively provided at both ends of the platform. A hydraulic component is provided at the upper end of the frame, including a pressure plate. An arc-shaped groove is formed on the lower surface of the pressure plate, allowing the pressure plate to move vertically. Platform grooves are formed at both ends of the platform. The fastening component includes a fastening strip hinged to the platform, and the fastening strip has a groove that is flush with the platform. The platform groove and the fastening groove fit together, allowing the two ends of the metering tube to be engaged between the platform groove and the fastening groove. During operation, the metering tube is placed on the platform, and its two ends are positioned by fastening components, so that it is engaged between the platform groove and the fastening groove. The two ends of the metering tube are mainly limited laterally by locking components. The metering tube can be moved along its length in the locking components. Then, the pressure plate moves down to press the "arch bridge" shaped part of the metering tube into a straight tube state, which can effectively perform the calibration operation of the metering tube with good calibration effect and high efficiency.
