Description
Technical field
The utility model belongs to the motor case processing technique field, especially relate to a kind of on punch press the ring cutting processing unit (plant) of the heavy wall type casing product of cutting processing motor case.
Background technology
The processing of motor case generally can be divided into sawing sheet, it is moulding to stretch, cutting, little processing, as punching, jet-bedding, screw thread cutting etc.Wherein cutting action is the casing semi-finished product that will stretch, and requires to cut the afterbody part according to the height dimension of specific product, makes it reach the desired physical dimension of design.
Cutting at present is divided into the cutting of lathe linear pattern and annular transverse cuts, the lathe linear pattern is cut into a kind of cutting mode that cutter directly cuts along the radial direction of casing product, exist that operating efficiency is low, processing precision of products is low, error is larger, and the easy flexural deformation of casing, the shortcomings such as percent defective height, thereby progressively replaced by annular transverse cuts.The annular transverse cuts is cutter along the rotate a circle cutting mode of cutting of the medial surface of casing product, compares with the cutting of lathe linear pattern, and annular transverse cuts has that precision is high, the efficient advantages of higher, thereby is widely used.
but because the cutting force of annular transverse cuts is less, common annular transverse cuts is applicable to the cutting of the casing product of casing wall thickness below 1.6mm, as notification number be: one-time-shaped mould is cut off in a kind of punching press that the Chinese utility model of CN201333481Y provides, comprise fixing punch and the die of motion, both install fixing by punch supporting seat and die supporting seat respectively, and be arranged on same axis, the punch below is provided with an annular stripping and slicing, the periphery of this annular stripping and slicing is stepped, the corner angle at middle part and the corner angle on top consist of respectively cutting edge and interior chamfering flange, the inner headed face of die is stepped, and the corner angle at middle part consist of outer chamfering flange.The cutting die that this patent provides is annular transverse cuts mode, can only be used for the thick casing product below 1.6mm of cutting machine shell wall, and for the casing of wall thickness greater than 1.6mm, because casing is thicker, to cause the end face out-of-flatness that cuts out, the height dimension accuracy error is large, and flatness does not reach requirement.During in addition due to ring cutting, cutter lateral shear rotation great efforts, mould easily produces skew and collision in cutting process, even cause mould to damage.
