Technical Field
[0001] The utility model relates to the technical field of plate shearing machine anti-warping, in particular to a plate shearing machine anti-warping device. Background Art
[0002] A shearing machine is a type of metalworking equipment primarily used for linear shearing of metal sheets of various thicknesses. It is a type of forging machine and is widely used in a variety of industries, including aviation, light industry, metallurgy, chemicals, construction, shipbuilding, automotive, electric power, electrical appliances, and interior design. Manual shearing machines use a manual handle to control the lowering of the upper blade to shear the sheet metal. This type of shearing machine is simple in structure and easy to use, making it suitable for small-scale sheet metal shearing operations.
[0003] However, in practice, shearing machines often encounter the problem of sheet material warping during the shearing process. This can affect shearing accuracy, leading to inaccurate sheet dimensions and uneven edges, which in turn affects subsequent processing and use. For example, sheet material warping can cause edges to bend or become uneven, which is unacceptable in high-precision machining applications. In manual shearing, uneven force or inconsistent operation can cause sheet material warping, affecting shearing accuracy. Utility Model Content

[0008] The plurality of tightening strips are evenly distributed on the table, and the length of the tightening strips increases successively from one end of the table to one end of the tool holder. The tightening strips of different lengths are used to fix and prevent the plates to be sheared of different sizes from warping.
[0009] In a further optional solution of the present application, the threaded portion of the shaft portion is connected to a fastening nut, which is rotated to restrict the shaft portion to the fixing frame to prevent the shaft portion from excessive shaking and falling. A copper ring is provided at the connection between the fastening nut and the fixing frame;
[0010] In a further optional solution of the present application, the connection between the rotating shaft and the fixing frame is of smooth design, and a connecting disk is provided at the inner end of the rotating shaft. The rotating shaft and the connecting disk form a "T"-shaped connecting piece, and the connecting block is fixed to the connecting disk by bolts;
[0011] In a further optional solution of the present application, the fixing frame is divided into a U-shaped frame and a mounting bar, the mounting bar is located at the side end of the U-shaped frame, and a round hole is opened on the mounting bar, and a bolt is inserted into the round hole to fix the fixing frame to the table;

The locking assembly and the locking hook work together to quickly and securely secure the retaining bar, simplifying the operation process. The stable sheet material makes the shearing operation smoother and improves shearing efficiency.
[0016] Preventing sheet material from warping during shearing reduces the risk of injury to operators and improves work safety. Multiple locking bars are evenly spaced across the tabletop, increasing in length to accommodate the needs of securing and preventing warping of sheet materials of varying sizes. Because the sheet material remains stable during shearing, additional wear on the shearing tool and tool holder caused by sheet material warping is reduced.
[0017] The underside of the retaining bar is bonded with a non-slip rubber strip, increasing friction with the sheet material and ensuring stability during shearing. The threaded portion of the shaft is secured with a locking nut, and a copper ring provides added stability to prevent excessive movement and falling.
