Description

Technical Field

[0001] The utility model belongs to the technical field of wire-cutting machine tools, and in particular relates to a pressing adjustment device and a medium-length wire-cutting machine. Background Art

[0002] Medium-speed wire EDM, a type of reciprocating high-speed wire EDM, implements multiple cutting functions on a high-speed reciprocating wire EDM, commonly known as "medium-speed wire EDM." Medium-speed wire technology refers to a composite wire EDM machine, where high-speed (8-12 m / s) wire is used for roughing and low-speed (1-3 m / s) wire for finishing. This results in relatively stable operation with minimal vibration. Multiple cuts reduce material deformation and errors caused by molybdenum wire loss, improving machining quality to a level between that of high-speed and low-speed wire EDM. During the cutting process, the workpiece must be accurately secured and clamped to prevent it from moving and affecting cutting accuracy and quality. However, conventional clamping adjustment devices can only clamp workpieces of the same size, limiting their applicability. Furthermore, the clamping adjustment device lacks a buffer mechanism during use, preventing the workpiece from being stably and reliably clamped.

[0003] To this end, a clamping and adjusting device for a medium-speed wire cutting machine with a bulletin number of "CN212371365U" is disclosed, comprising a cutting table and a frame. A side panel is fixedly connected to one side of the top of the cutting table, the frame is fixedly connected to the upper side of the side panel, a servo motor is mounted on the side of the side panel near the upper end, the output shaft of the servo motor is fixedly connected to a rotating shaft via a coupling, the end of the rotating shaft away from the servo motor passes through the interior of the side panel and the frame respectively, extends toward the inner side of the frame and is welded and fixed with a threaded column. The clamping effect is better, and the distance between the movable pressure block and the fixed pressure block can be automatically adjusted as needed, making the device more applicable and suitable for cutting workpieces of different sizes. At the same time, under the buffering action of the second spring, the movable pressure block and the fixed pressure block can well clamp the workpiece, making the cutting of the workpiece more stable and reliable.

[0004] However, for the above-mentioned medium-speed wire cutting machine clamping and adjusting device, although when the movable pressure block and the fixed pressure block have just clamped and fixed the workpiece, the movable pressure block is still moving, the movable pressure block pushes the slide to move, and drives the slide column to move in the slide and compresses the second spring to move. Under the buffering action of the second spring, the movable pressure block and the fixed pressure block can well clamp the workpiece, so that the cutting of the workpiece can be more stable and reliable. However, there are still the following more obvious defects during use: in the process of the workpiece being clamped and cut, since the movable pressure block and the fixed pressure block are fixed structures, the workpiece cannot be rotated to change the cutting position in the clamped state, so that the staff needs to manually adjust the position of the workpiece and then clamp it. This process easily causes the workpiece to change the cutting position and cause position offset, and also affects the progress of the workpiece cutting. Utility Model Content

Since the workpiece is clamped and will not deviate during rotation, the workpiece can be rotated and adjusted to the cutting position after being clamped, thereby realizing the rotation adjustment of any cutting position of the workpiece, further improving the multi-directional rotation cutting operation of the workpiece, and at the same time improving the working efficiency of the medium-length wire cutting machine.

At the same time, the staff can change the clamping force in time to ensure that the workpiece is safer during clamping and fixing. BRIEF DESCRIPTION OF THE DRAWINGS
