Embodiment Construction

[0019] figure 1 It is a schematic diagram of the product structure of this embodiment. It can be seen from the figure that the thin-walled cylindrical workpiece is 400mm long, the 50mm long wall thickness at both ends is 2.5mm, and the nearly 300mm long wall thickness in the middle is only 1mm. Workpieces with a structure like this, if mass-produced, are usually produced by the thickening process at both ends of the steel pipe with a wall thickness of 1mm. However, for processing plants without pier roughing equipment, the cost of single-room production pier roughing is very high, and conventional turning methods cannot be realized.

[0020] In order to realize the single-piece processing and production of thin-walled cylindrical workpieces, the present invention provides a simple turning tool, such as figure 2 As shown, it is a schematic diagram of the structure of the thin-walled cylindrical workpiece product and its tooling in this embodiment. Pass the stepped mandrel 4 ...

Abstract

The invention provides a turning tool and a turning method for thin-walled cylindrical workpieces. The turning tooling includes a mandrel, plug without hole, plug with hole and nut. The mandrel passes through the inner hole of the workpiece, and the two ends are respectively installed with plugs without holes and with holes, and the nuts at both ends of the mandrel are tightened, the mandrel and the workpiece are combined into one, and the wax injection hole is injected into the mandrel and the workpiece. Fill the cavity with paraffin. The processing steps of thin-walled cylindrical parts using this turning tool include: 1) rough turning the outer circle, inner hole and end face; 2) finishing turning inner hole and end face, the length conforms to the drawing size; 3) finishing turning inner hole to the drawing requirements; 4) Combine the tooling with the workpiece; 5) Position and install the two ends of the mandrel with thimbles; 6) Use coolant to finish the outer circle to the requirements of the drawing. By adopting the above-mentioned turning tool and processing method, the problem of deformation of the thin-walled cylindrical workpiece in turning is solved, and the machining accuracy of the thin-walled cylindrical workpiece is guaranteed.

Description

technical field [0001] The invention belongs to the field of mechanical processing and provides a turning tool and a turning processing method for thin-walled cylindrical parts. Background technique [0002] With the development of the equipment industry and the improvement of processing capabilities, thin-walled parts have been increasingly widely used in various industrial sectors. The application of thin-walled cylindrical workpieces on equipment is increasing day by day. Once the workpiece is damaged, it is difficult to process it by turning in a short time. Turning deformation of thin-walled workpieces has always been a problem that plagues turning processing. The causes of deformation of thin-walled cylindrical workpieces during turning include clamping force, turning force, turning heat, positioning error and elastic deformation, among which the clamping force and turning force have the greatest influence on deformation.
