Description

Technical Field

[0001] The present invention relates to the technical field of cutting equipment, and in particular to an auxiliary equipment for plate cutting and a cutting method thereof. Background Art

[0002] Plate cutting is a common processing technology used to cut plates into specific sizes and shapes. Plate cutting usually adopts plasma cutting and laser cutting. These two cutting methods use CNC operation to perform large-scale cutting processing. After setting the parameters during the cutting process, the material to be cut is placed on the working platform of the laser cutting equipment, and the cutting path and positioning are designed. However, when performing large-scale cutting, the position of each plate needs to be positioned before the equipment can be started for cutting. At the same time, a layer of slag is attached to the surface of the cut plate. It is necessary to clean the slag while collecting the cut products, which seriously affects the work efficiency.

[0003] Therefore, in view of the above problems, an auxiliary device for plate cutting and a cutting method thereof are proposed to solve the above problems. Summary of the invention

[0004] In view of the deficiencies of the prior art, the present invention develops an auxiliary device for plate cutting and a cutting method thereof, which can quickly position a large number of plate cuttings and automatically clean the slag generated on the surface of the plate.

[0005] The technical solution to the technical problem solved by the present invention is: an auxiliary equipment for plate cutting, including an installation frame, the installation frame is arranged on a cutting machine, the plate to be cut on the cutting machine is located in the installation frame, a positioning part and a cleaning part are arranged on the installation frame, the positioning part includes multiple limit sleeves and multiple limit screws, the limit screws are threadedly connected to the limit sleeves, and the side edges of the multiple limit screws are respectively overlapped on one side of the plate to be cut.

[0006] When large quantities of repeated cutting of plates are required, the plates are quickly positioned through the positioning part set on the installation frame, which reduces the time of manual repeated positioning and adjustment and improves the cutting efficiency. The positioning accuracy is improved by positioning the edge of the plate through multiple limit screws. At the same time, the limit screw is threadedly connected with the limit sleeve, so that the limit screw can adjust the height to position plates of different thicknesses. At the same time, the cleaning part cleans the slag on the surface of the plate after cutting.

A limit sleeve is arranged at the end of the extension block away from the fixed column. A limit structure is arranged on the fixed column.

[0008] By setting a fixed column and a connecting shaft, the positioning table, the extension block and the limit screw can be rotated. After the limit screw completes the positioning, the connecting shaft is rotated so that the positioning table, the extension block and the limit screw do not affect the subsequent cutting of the plate by the cutting machine.

A cutting method using the auxiliary equipment for plate cutting according to any one of claims 1 to 5, characterized in that The steps include: S1: Design the cutting path of the plate and design adjacent parts to share a common edge during programming; S2: The plate to be cut is placed in the installation frame (1), and the connecting shaft (5) is rotated to drive the positioning table (6), the extension block (7) and the limit screw (3) to rotate. When the limit screw (3) overlaps the edge of the plate, the rotation stops, and at the same time, the position of the slip ring (14) is locked by the second locking bolt (19), and the limit screw (3) is returned to its original position; S3: Start the cutting machine and cut the plate on the cutting machine according to the set program; S4: After the cutting is completed, the cleaning unit is started to clean the slag generated on the surface of the plate, and then the cut plate is removed; S5: placing the next plate, rotating the connecting shaft (5) so that the limiting rod (12) of the positioning block (17) overlaps the baffle (16), and the position of the limiting screw (3) is the position where the edge of the plate should be placed. The position of the plate is made the same as the position of the plate cut for the first time by using multiple limiting screws (3); S6: Start the cutting machine to repeat cutting.
