Embodiment Construction
[0019] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0020] Such as figure 1 As shown, a special tool for prying mold position, the tool includes a fixed shaft 1, a working head 2 and a knife grain 3, wherein the fixed shaft 1 and the working head 2 are integrally formed as a whole, and the working head 2 is a section of cylinder 21, so The end of the cylinder 21 is processed into a chamfer 23, the cutter grain 3 is in the shape of a square sheet, and two corners on one side of the knife grain extend out of the chamfer 23 and the end face of the working head 2 respectively, and the chamfer 23 A circle of concave grooves 22 is formed at the junction with the cylinder 21, that is, the structure on the working head from top to bottom is a circular platform, a concave ring, and a cylinder in sequ...

Abstract
The invention relates to a prying die position special tool and a prying die position machined by the prying die position special tool. The tool comprises a fixing shaft, a working head and a blade; the fixing shaft and the working head are integrally formed into a whole; the working head is a segment of a cylinder, the end of the cylinder is machined into a chamfer, and a ring of a concave grooveis formed in the junction of the chamber and the cylinder; the end faces of the two sides of the working head are each provided with a gap in the axial direction, and then two smooth planes are formed on the two sides of the working head correspondingly; and one smooth plane of the opposite sides of the two gaps is provided with a groove of which the shape is matched with that of the blade, a screw hole is formed in the center of the groove, and the blade is fixed to the groove through a screw, so that the edge of one corner of the blade stretches out of the chamfer. According to the scheme,point cutting (one-point cutter) of traditional bevel machining is changed into plane cutting through blade adjusting, therefore, the efficiency and the quality are improved, and the surface smoothness of the prying die position reaches Rz smaller than or equal to 6.3 micrometers.
Description
technical field [0001] The invention relates to the field of technical machine tool processing parts, in particular to a special tool for prying mold positions. Background technique [0002] In order to ensure the smoothness of the mold blank prying position, the current technical processing can only choose a small cutting amount, and the efficiency is very slow. In order to improve the quality requirements (the surface finish of the prying die position reaches Rz≦6.3um) and improve the efficiency, we design The production of a special knife for prying mold positions can increase the efficiency by five times and improve the quality. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a special cutting tool for prying dies to solve the low efficiency of traditional processing of prying dies, and the rough surface processed by this project affects the overall appearance of the mold base, and the...
