A device and method for processing arc-curved grooves

Abstract

The invention relates to a device for processing an arc curve groove. The device comprises a traveling car, wherein a cutting part and a limiting part are arranged on the traveling car, the limiting part comprises a position clamping part and a connecting rod connecting the position clamping part and the traveling car, and the position clamping part is in contact with the edge of a part to be processed and is used for limiting cutting tracks. The method comprises the following steps: perpendicularly cutting curves, and processing grooves in curve edges. The device and method, disclosed by the invention, has the advantages that the production efficiency of opening the curve groove in an arc (heteromorphic) steel plate is improved, and the product quality is improved.

Description

technical field [0001] The invention relates to a device and a method for processing the grooves of arc or curved parts in steel structure engineering, the grooves of annular butt joints of pressure steel pipe reducing pipes, and the grooves of intersecting lines of bifurcated pipes. Background technique [0002] In hydropower and water conservancy projects, arc gates are often used as working gates in dam water retaining and flood discharge structures. In hydropower projects with wide riverbeds, arc gates are in large batches, mostly in the form of surface holes, with large sizes, even There are more than 20 sets of arc doors of one specification. However, the arc gates in the flood discharge structures of the Canyon Power Station are generally not large in batches and have many specifications, and are generally arranged in bottom holes, deep holes, and middle holes. The main girder web, edge beam web, diaphragm, lug web, etc. in the arc gate are all arc curved members, an...

AI Technical Summary

Problems solved by technology

The main girder web, edge beam web, diaphragm, lug web, etc. in the arc gate are all arc curved members, and the arc curved members can be cut by CNC cutting machine, but it cannot meet the requirements of the arc surface. Groove, the arc surface of small parts can be processed by machine tool, but for the main longitudinal beam type arc door parts with a length of more than 12 meters, the equipment requirements for machining bevel are high, and most of the equipment is too long because of the workpiece Can not meet the processing requirements

[0003]The semi-automatic cutting machine makes arc-shaped grooves. The traditional method is to make an arc-shaped track according to the curvature radius of the workpiece. The semi-automatic cutting machine runs on the arc-shaped track. Due to the unevenness of the track and the tightness of the connection between the two tracks, it will have a great impact on the cutting quality

At the same time, due to the low accuracy of the track curvature radius, the radian deviation of the opening groove is relatively large, and the width of the groove cannot meet the specification requirements.
