The drift external diameter 0.2mm-0.8mm bigger than the endoporus of workpiece of described stretching punching pin lower end.
The material selection Cr12 of described stretching punching pin, heat treatment hardness is GRC58-62, and it is 0.4-0.8 that surface finish processes its roughness, and stretcher strain amount is 12%-20%, and the deflection for mild steel is 20%-40%.
Through hole in the middle of described stretching die includes into die orifice, work strip and goes out die orifice, described enter die orifice identical with the diameter going out die orifice, described enter to be provided with between die orifice and work strip into modular angle, described go out between die orifice and work strip, to be provided with out modular angle, described work strip and enter to be provided with knuckle between modular angle.
Described enter die orifice and go out the diameter of die orifice and be all higher than blank diameter 5mm-15mm, the diameter of described work strip is 5mm-15mm, described in enter modular angle be 12 °-16 °, described in go out modular angle be 12 °-15 °, described knuckle is R4mm.
The material of described stretching die adopts T10A cold work die steel, heat treatment HRC50-60.
Described work strip is polished skidding with entering modular angle surface, and roughness is 0.4-0.8.
Compared with prior art the present invention is had the beneficial effect that
The present invention is high to the endoporus machining accuracy of perforating charge cartridge case, and the speed of punching press, stock utilization add much larger than machine speed, stock utilization, the quality that the quality of product adds also much larger than machine, the lathe, personnel and the number of cutters that additionally need are few, decrease entreprise cost, improve the competitiveness of enterprise. Drawing die sizing internal via shape and size, compared relative to former rough turn endoporus, its maximum benefit is owing to material defines surface flow harden after cold stretch, its hardness can arrive about HB190-230, be conducive to the perforating bullet resistance to deformation power when pressing, improve the pressing power of perforating bullet thus improve Types of Medicine density, what add perforating bullet wears the degree of depth, and this is that rough turn endoporus in the past is beyond one's reach.
Accompanying drawing explanation
Below by accompanying drawing, the specific embodiment of the present invention is described in further detail.
Fig. 1 is the structural representation of the present invention;
Fig. 2 is the through-hole structure schematic diagram of the present invention.
In figure: 1 be cope match-plate pattern, 2 be red seat, 3 for stretching punching pin, 4 be stretching die pressing plate, 5 be workpiece, 6 be stretching die, 7 be die shoe, 8 for entering die orifice, 9 be work strip, 10 for going out die orifice, 11 for entering modular angle, 12 for going out modular angle, 13 for knuckle.
Detailed description of the invention
The invention will be further described in conjunction with accompanying drawing for example below.
As depicted in figs. 1 and 2, the present invention includes cope match-plate pattern 1, red seat 2, stretch punching pin 3, stretching die pressing plate 4, stretching die 6 and die shoe 7, cope match-plate pattern 1 is fixedly connected with stretching punching pin 3 by red seat 2, stretch and can place workpiece 5 between punching pin 3 and stretching die 6, the drift external diameter 0.2mm-0.8mm bigger than the endoporus of workpiece 5 of its lower end, material selection Cr12, heat treatment hardness is GRC58-62, it is 0.4-0.8 that surface finish processes its roughness, stretcher strain amount is 12%-20%, deflection for mild steel is 20%-40%, the material of stretching die 6 adopts T10A cold work die steel, heat treatment HRC50-60, centre is provided with through hole, upper end is provided with stretching die pressing plate 4, lower end has been fixedly connected die shoe 7, through hole includes into die orifice 8, work strip 9 and go out die orifice 10, the diameter entering die orifice 8 and go out die orifice 10 is identical, it is all higher than blank diameter 5mm-15mm, the diameter of work strip 9 is 5mm-15mm, and enter and be provided with into modular angle 11 between die orifice 8, and go out and between die orifice 10, be provided with out modular angle 12, and enter and between modular angle 11, be provided with knuckle 13, entering modular angle 11 is 12 °-16 °, going out modular angle 12 is 12 °-15 °, knuckle 13 is R4mm, work strip 9 is polished skidding with entering modular angle 11 surface, roughness is 0.4-0.8.
When internal via shape and size are shaped by the drawing die of the present invention, concrete operations are as follows:
