Description

Technical Field

[0001] The utility model belongs to the technical field of shearing of metal sheets, in particular to a precision right-angle shearing machine for magnesium alloy sheets. Background Art

[0002] With the continuous development of science and technology, people in the 3C electronics field are no longer solely focused on performance, but are also beginning to pay attention to its lightweight application. Currently, magnesium alloys are light weight, high strength, good thermal conductivity and electrical conductivity, and have excellent electromagnetic shielding and good machinability, making them an ideal material for 3C electronic products.

[0003] However, the magnesium alloy preparation process is complex, requiring multiple rolling, heat treatment, shearing, and grinding steps, resulting in low production efficiency. The consistency of the sheet's dimensions is difficult to ensure during production. Early deliveries are typically cut using shears, which cannot achieve dimensional consistency. This results in low product qualification rates and consistently high production costs, significantly limiting the promotion and application of magnesium alloy sheet within the industry. Magnesium alloy processing technology issues have become a roadblock to improving the quality and reducing costs of magnesium alloys and expanding their application, but market demand for magnesium alloy sheet has not diminished.

[0004] Currently, the external dimensions of magnesium alloy sheets are mainly controlled by repeatedly adjusting the size and cutting them on a shearing machine. This has low precision and cannot guarantee dimensional tolerances. It is also inefficient because only one side can be cut at a time and the squareness is poor. Utility Model Content

[0005] In response to the above technical problems, the utility model provides a precision right-angle shearing machine for magnesium alloy plates, which improves the cutting accuracy of magnesium alloy plates, ensures product size and right angle; and improves production efficiency by cutting two sides at a time.

[0008] At least three holes are opened on another pair of adjacent right-angled sides of the working platform for installing the guide column device. The upper scissor device is sleeved on the guide column device. A spring device is installed between the upper scissor device and the working platform. The lower part of the guide column device is fixedly connected to the hydraulic system.

[0009] The upper scissor device comprises an L-shaped pressing plate at the upper portion and an L-shaped scissors at the lower portion.

[0010] The lower scissor device is a tool steel plate with a T-slot on the upper side for installing a ruler.
