Plate trimming machine

Abstract

The invention discloses a plate trimming machine, which comprises a base, a workbench, a saw beam and disk saw devices, wherein one movable disk saw device is arranged on the right side of the saw beam; two movable disk saw devices are arranged on the left side of the saw beam. The plate trimming machine is characterized in that the saw beam is connected with the top ends of two upright posts to construct a gantry; the base below the saw beam extends from the left side and the right side of the saw beam, and is separated from the two upright posts; a movable workbench and a main driving device connected with the workbench are arranged on the base; workpiece clamping tongs for clamping in the horizontal direction are arranged on front side, back side, left side and right side of the workbench; a plurality of gantry hole devices for supporting workpieces in a rolling way are arranged in an arrayed manner on the workbench respectively; each gantry hole device consists of a ball and a ball base. The plate trimming machine is high in trimming accuracy, high in stability and convenient for machining.

Description

Technical field [0001] The invention relates to a metal sawing equipment, in particular to a plate trimming machine suitable for high-precision sawing. Background technique [0002] Nowadays, the aerospace industry is developing rapidly, and its widely used aluminum alloy sheet processing accuracy requirements continue to increase. Because many aerospace aluminum alloy sheet materials are mainly formed by casting, then sliced ​​by a sawing machine, and then trimmed by an edge trimmer. Therefore, the trimming processing of the trimming machine will directly affect the shape processing accuracy of the sheet material. [0003] The conventional edge trimmer in the prior art usually includes a base, a workbench, a saw beam, a circular saw device, and a pressing device. The circular saw device is composed of a circular saw blade, a drive motor, a sliding support plate, a servo motor and Drive screw composition. A saw beam support frame is fixed on the four sides of the base, and the ...

AI Technical Summary

Problems solved by technology

[0004] 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 processed products is low

2. Since the workpiece material is processed by rotation and compression of the downward-pressing compression device, the workpiece material is easy to loosen during rotation and compression, resulting in processing errors and affecting the processing accuracy, and 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
