Abstract

The invention discloses a linear cutting rig for machining a pyramid of a thin-walled tube. The linear cutting rig for machining the pyramid of the thin-walled tube comprises a base plate, a bearing bush and a positioning body, wherein the base plate is fixed with the outer wall of the bearing bush; a bearing, a spacing gasket and a spacing bush are arranged in the bearing bush; a dividing plate sleeves an end surface of the bearing bush; an annular projection of the dividing plate clings to an inner ring of the bearing; a positioning screw pin is screwed in a screw hole in a side wall of the dividing plate and is inserted in a positioning hole of the bearing bush; a positioning shaft of the positioning body sequentially penetrates in the bearing bush and a center hole of the dividing plate and is combined with a nut; and a surface of a clamping plate is provided with a positioning hole and quick pincers. A three-dimensional pyramid surface is machined by a two-dimensional linear cutting machine tool, the circumstance that cutting burrs are generated on cutting portions or the cutting portions deform is avoided by a corrosion machining mechanism, a machined pipe fitting is low in stress, the machining quality of the pyramid surface is high, and the machining precision is also high.

Description

technical field [0001] The invention belongs to the field of wire cutting processing, and in particular relates to a device for wire cutting processing of thin-walled pipe pyramids. Background technique [0002] The mouth of metal materials with high precision used in the industry is equipped with thin-walled pipe fittings with pyramids. The thickness of the thin-walled pipe fittings is about 0.1mm. The pyramids for processing small-sized thin-walled pipe fittings need to be suitable for machining 3D workpieces. Mechanical cutting machine tool processing. Due to the thin wall of the pipe fittings, cutting burrs or deformation often occur at the cut. It affects processing accuracy and production efficiency, and the production cost is relatively high, so it is not suitable for mass production. Contents of the invention [0003] The present invention is proposed to solve the problems existing in the prior art, and its purpose is to provide a device for processing thin-walle...
