Embodiment Construction

[0012] Such as figure 1 It is a schematic diagram of the processing process of the present invention. This thin-wall processing has the following processes: 1) clamp the workpiece blank on the chuck fixture; 2) fix the special tool 1 capable of processing the required thin-wall thickness on the feeder, And make the line of two cutting points on the outer diameter processing cutter head 2 and the inner diameter processing cutter head 3 on the special tool 1 perpendicular to the feeding direction of the cutter 1; 3) feed cutting; 4) cutting and blanking. Such as figure 1 The cutting tool 1 on the handle comprises a knife handle 11, a left front fork 12 and a right front fork 13, and the left front fork 12 and the right front fork 13 protrude forward in a U-shape at the front end of the knife handle 11, and are respectively fixed on the left front fork 12 and the right front fork 13 The outer diameter processing cutter head 2 and the inner diameter processing cutter head 3, the ...

Abstract

The invention relates to a mechanical preparing technology, especially to a thin wall preparing process and private knife device. The process comprises following steps: (1) grasping work piece blank; (2) fixing private knife for thin wall preparation on feed knife carrier, and the two cutting points of outer and internal diameter cutter head is vertical to feeding direction; (3) cutting; (4) cutting blank. Said knife device comprises knife handle, left front fork and right front fork, the left and right front fork extends forwardly to form U shape and they are equipped with outer diameter processing cutter head and internal diameter processing cutter head, the distance between two knife head cutting point is corresponding to the thickness required by thin wall element. The invention is characterized by high thin-walled processing efficiency and stable quality of thin-walled element.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a thin-wall processing technology and a special tool thereof. Background technique [0002] Thin-walled parts such as thin-walled cylindrical tubes, thin-walled conical tubes, and thin-walled circular gaskets are often used in the mechanical field because they can meet some special purposes. The method of mold processing such as stretching and extrusion can be used. For thin-walled parts that cannot be processed by this mold, the method of turning is generally used. Due to the poor structural strength of thin-walled parts, in order to ensure the dimensional accuracy of the parts, The processing method is to first process the inner diameter of the part to the size requirement, and then process the mandrel fixture that matches the inner diameter of the part, and then put the part with the processed inner diameter on the mandrel to process the outer diameter. [0003]...
