Description

Sheet trimming machine

technical field

The invention relates to a metal sawing device, in particular to a board edge trimmer suitable for high-precision sawing.

Background technique

Today, the aerospace industry is developing rapidly, and the processing accuracy of the widely used aluminum alloy sheets is constantly improving. Because many aluminum alloy sheet materials for aerospace are mainly formed by casting, then sliced by sawing machine tools, and then trimmed by edge trimmers. Therefore, the edge trimming of the edge trimmer will directly affect the shape processing accuracy of the sheet material.

The common trimming machine of prior art usually comprises base, workbench, saw beam, circular saw device and pressing device, and described circular saw device is all made up of circular saw blade, driving motor, sliding support plate, servo motor and Composition of drive screw. The four sides of the base are fixed with a saw beam support frame, the four walls of the saw beam support frame are provided with protective covers, and the movable saw beam is arranged on the top ends of both sides of the saw beam support frame, and the circular saw is driven by the saw beam. The device moves left and right along the front and back tops of the saw beam support frame. The workbench is fixed on the base, and the workbench is provided with a pressing device which can be wheeled and pressed down from top to bottom to press the plate workpiece material. The right side of the saw beam is provided with a movable circular saw device for sawing the right side of the workpiece, and the left side of the saw beam is respectively equipped with two movable circular saw devices for sawing the front and rear sides of the workpiece. device. When the above-mentioned ordinary edge trimmer is working, the left and right sides and the front and rear sides of the workpiece material are pressed and fixed up and down through the pressing device on the workbench, and then the circular saw device on the right side of the saw beam is started to make it move forward and backward on the saw beam. Move the right side of the sawing workpiece. Then start the sawing beam to move left and right along the top of both sides of the supporting frame along the sawing beam, and simultaneously drive the two circular saw devices on the left side of the sawing beam to move the front and rear sides of the sawing workpiece.

However, the above-mentioned common edge trimmer has the following problems in the edge trimming process. One, the saw beam will vibrate when it moves on the saw beam support frame, thereby affecting the work of the circular saw blades doing cutting motion at the same time, reducing the impact of the circular saw. The sawing stability and sawing accuracy of the device, the quality of the processed product is low. 2. Since the workpiece material is pressed and processed by the pressing device that presses down, it is easy to loosen the workpiece material when it is rotated and pressed, resulting in machining errors and affecting the machining accuracy. Moreover, the structure is not compact and it is inconvenient to clamp the workpiece. 3. The protective cover around the base needs to have enough height to prevent the sawdust from splashing out, but the height of the protective cover is limited by the height of the saw beam support frame. The improvement of the side of the saw beam support frame will cause the circular saw The distance between the circular saw blade in the device and the saw beam increases, and the greater the distance increases, the greater the vibration of the circular saw blade during processing, the worse the sawing stability, and the lower the processing accuracy.
