Description
Technical field
The present invention relates to drawing die technical field, more specifically, it is related to a kind of production perforating charge cartridge case of being applied to
Drawing die.
Background technology
Perforating oil gas well is a key technology in petroleum exploration ＆ development, and the effect of perforating bullet is exactly to be shot through underground envelope
Close the sleeve pipe of target zone, cement sheath and go deep into target zone, form effective seepage flow siphunculus of target zone and well casing, ensure that Oil/gas Well obtains
Due production capacity is obtained, and the application of perforating bullet in other respects is also found and used constantly.
Perforating charge cartridge case is the main composition part of perforating bullet, and the method for producing perforating charge cartridge case at present mainly has hot extrusion
Two kinds of blank and cold extrusion blank, two methods are required for using drawing die come perforating charge cartridge case internal via shape and the chi of shaping
It is very little, but existing mold fabrication cycle is grown, difficulty of processing is big, and the endoporus being finally molded is of poor quality, entreprise cost increase, therefore,
It is necessary to be improved prior art.
The content of the invention
In the presence of overcoming the shortcomings of prior art, there is provided one kind make it is simple, improve productivity and quality, drop
The drawing die for being applied to production perforating charge cartridge case of low production cost.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is：
A kind of drawing die for being applied to production perforating charge cartridge case, including cope plate, red seat, stretching punching pin, stretching molding
Plate, stretching die and die shoe, the cope plate are fixedly connected by red seat and stretching punching pin, are provided among the stretching die logical
Hole, workpiece can be placed between the stretching punching pin and stretching die, the stretching die upper end is provided with stretching moulded board, the stretching
Mould lower end is fixedly connected and has die shoe.
The drift external diameter of the stretching punching pin lower end is bigger 0.2mm-0.8mm than the endoporus of workpiece.
The material selection Cr12 of the stretching punching pin, heat treatment hardness HRC58-62, its roughness of surface polishing
For 0.4-0.8, stretcher strain amount is 12%-20%, and the deflection for mild steel is 20%-40%.
Through hole among the stretching die is included into die orifice, working band and goes out die orifice, it is described enter die orifice with going out the straight of die orifice
Footpath is identical, described to enter to be provided with into modular angle between die orifice and work band, described to go out to be provided with out modular angle between die orifice and work band,
The work band and enter and be provided with knuckle between modular angle.
It is described to enter die orifice and to go out the diameter of die orifice and be all higher than blank diameter 5mm-15mm, a diameter of 5mm- of the work band
15mm, it is described enter modular angle be 12 ° -16 °, it is described go out modular angle be 12 ° -15 °, the knuckle is R4mm.
The material of the stretching die uses T10A cold work die steels, is heat-treated HRC50-60.
The work band and enter modular angle surface and be polished skidding, roughness 0.4-0.8.
Compared with prior art the advantageous effect of present invention is that：
The present invention is high to the endoporus machining accuracy of perforating charge cartridge case, and the speed of punching press, stock utilization are much larger than machine
Speed, the stock utilization added, the quality of product is also much larger than the quality that machine adds, the lathe additionally needed, personnel and cutter number
Amount is few, reduces entreprise cost, improves the competitiveness of enterprise.Drawing die sizing internal via shape and size, relative to former
Rough turn endoporus compare, its maximum benefit is due to that material forms surface flow harden after cold stretch, and its hardness can
To reach HB190-230 or so, be advantageous to anti-deformation force of the perforating bullet in pressing, improve the pressing power of perforating bullet so as to carry
High Types of Medicine density, add perforating bullet wears depth, and this is that former rough turn endoporus is unable to reach.
Brief description of the drawings
The embodiment of the present invention is described in further detail below by accompanying drawing.
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 it is cope plate, 2 be red seat, 3 be stretching punching pin, 4 be stretching moulded board, 5 be workpiece, 6 is stretching die, 7
For die shoe, 8 be into die orifice, 9 be work band, 10 be die orifice, 11 be into modular angle, 12 be modular angle, 13 be knuckle.
Embodiment
The invention will be further described for example below combination accompanying drawing.
As depicted in figs. 1 and 2, the present invention includes cope plate 1, red seat 2, stretching punching pin 3, stretching moulded board 4, stretching die 6
With die shoe 7, cope plate 1 is fixedly connected by red seat 2 and stretching punching pin 3, and work can be placed between punching pin 3 and stretching die 6 by stretching
Part 5, the drift external diameter of its lower end is bigger 0.2mm-0.8mm than the endoporus of workpiece 5, material selection Cr12, and heat treatment hardness is
HRC58-62, its roughness of surface polishing are 0.4-0.8, and stretcher strain amount is 12%-20%, for the deflection of mild steel
For 20%-40%, the material of stretching die 6 uses T10A cold work die steels, is heat-treated HRC50-60, centre is provided with through hole, upper end
Stretching moulded board 4 is provided with, lower end, which is fixedly connected, die shoe 7, and through hole includes into die orifice 8, work band 9 and goes out die orifice 10, enters
Die orifice 8 is identical with the diameter for going out die orifice 10, is all higher than blank diameter 5mm-15mm, a diameter of 5mm-15mm for the band 9 that works, with entering
It is provided between die orifice 8 into modular angle 11, with going out between die orifice 10 to be provided with out modular angle 12, transition circle is provided between modular angle 11 with entering
Angle 13, enter modular angle 11 for 12 ° -16 °, go out modular angle 12 for 12 ° -15 °, knuckle 13 be R4mm, work band 9 with enter the table of modular angle 11
Face is polished skidding, roughness 0.4-0.8.
When the drawing die of the present invention is shaped to internal via shape and size, concrete operations are as follows：
