Description
Technical field
The present invention relates to the processing mould of stainless steel nest silk bobbin, and the processing method of this product, the textile workpiece technology belonged to.
Background technology
Silk is made in the silk process, needs the nest wire process, just uses nest silk bobbin.Existing nest silk bobbin mainly contains plastic bobbin and aluminium alloy bobbin according to the manufactured materials difference, and the characteristics of plastic bobbin are easy to manufacture, and cost is low, but the shortcoming of its existence is a bad mechanical strength, and non-refractory is easily aging, especially ruptures easily at neck.The shortcoming that the aluminium alloy bobbin exists is easily oxidation of surface, and oxide layer is polluted silk, can cause product rejection.So people adopt stainless steel material to make nest silk bobbin in the recent period, because stainless steel material moulding difficulty is used welding method, processing trouble, expense height, poor surface smoothness.
Summary of the invention
The purpose of this invention is to provide a kind of global formation, make product processing simple, smooth surface, the processing mould of the stainless steel nest silk bobbin that mechanical strength is good.
Another object of the present invention provides the processing method of stainless steel nest silk bobbin.
The technical scheme of stainless steel nest silk bobbin processing mould of the present invention is: be to be shaped on die cavity in the mould, core rod is installed in the die cavity, it is characterized in that described mould is an assembling die more than a section or a section, described die cavity is cylinder chamber and bulging end cap chamber alternate composition of merogenesis, core rod is installed in die cavity, in the die cavity between stainless steel tube insertion mould and the core rod, between core rod and the stainless steel tube seal is installed, one at mould has solid plate, there is jack unit the outer end of core rod, in the die cavity of one of solid plate, blocking device is installed, is shaped on liquid injection hole in the blocking device.Die sleeve is arranged outside mould, and there is moving platen the mould other end, and core rod passes moving platen.Its described blocking device pattern in the technical scheme of specific product is many, fairly simple embodiment has one to clamp the expansion head, clamping an expansion outer wall matches with mould inner wall, clamp the tapered hole of endoporus of expansion head, bellmouth matches with the tight chock of cone, is being shaped on liquid injection hole in the tight chock.Jack unit for core rod can be a hydraulic pressure cylinder assembly.Its tight chock sectional area S in die cavity is greater than the sectional area B that clamps the expansion head.This processing mould adopts segmentation, and die cavity merogenesis and diameter difference, and the cylinder chamber diameter is exactly the diameter of stainless steel tube, also is the diameter of nest silk bobbin after the moulding, so this diameter is according to the model design of nest silk bobbin.The end cap chamber of bulging is two cephalic pars of system nest silk bobbin, and diameter also is consistent with the two end plates of nest silk bobbin, adopts and injects shaped by fluid pressure.Using this mould, to make nest silk bobbin technology simple, and the production efficiency height need not welding, smooth surface, Stainless Steel nest silk bobbin does not pollute, be difficult for broken, high temperature resistant, characteristics such as mechanical strength is good.
The processing method of stainless steel nest silk bobbin of the present invention, the tight chock and the mould that are its blocking device push clamping to the stainless steel tube head, its liquid injection hole UNICOM hydraulic cylinder, hydraulic cylinder is fluid injection body (as oiling) in die cavity, adopt hydraulic pressure to pressurizeing in the stainless steel tube, make stainless steel tube produce the expansion injection moulding at position, mould bulging end cap chamber, the stainless steel tube behind the injection moulding has expansion joint, the annular of expansion joint being carried out symmetry is cut apart, and makes nest silk bobbin.
Description of drawings
Fig. 1 is the processing mould structural representation of stainless steel nest silk bobbin of the present invention;
Fig. 2 is that stainless steel nest silk bobbin is cut apart the back schematic diagram.
The specific embodiment
The invention discloses a kind of processing mould and processing method of stainless steel nest silk bobbin.Its described processing mould as shown in Figure 1, be to be shaped on die cavity in the mould, core rod is installed in the die cavity, be characterized in that mould can be one section (unitary mould) or be divided into several sections assembling die 2, and described die cavity be the cylinder chamber 3 (diameter is equivalent to the size of nest silk bobbin) of merogenesis and bulging end cap chamber 4 (diameter is equivalent to nest silk bobbin two ends size) mutually between section form, core rod 5 is installed in die cavity, core rod withdraws from one section outward after having made first stage building, in the die cavity between stainless steel tube 6 insertion moulds 2 and the core rod 5, seal 7 is installed between core rod and stainless steel tube 6, one at mould has solid plate 9, there is jack unit the outer end of core rod, described jack unit generally adopts hydraulic pressure cylinder assembly, adds man-hour core rod to be withstood, and does not make its activity.In the die cavity of 9 one of solid plates, blocking device is installed, is shaped on liquid injection hole in the blocking device.In order to strengthen the intensity of mould, particularly segmented die, die sleeve 1 is arranged outside mould 2, there is moving platen 12 the mould other end, and core rod 5 passes moving platen 12.Its technical scheme of described blocking device is a lot, for example shown in Figure 1, be to clamp expansion 8, clamping an expansion outer wall matches with mould inner wall, generally be to clamp the stainless steel tube head, clamp the tapered hole of endoporus of expansion head, bellmouth matches with the tight chock 10 of cone, tightly be shaped in the chock liquid injection hole 10 '.Its tight chock 10 sectional area S in die cavity is greater than the sectional area B that clamps expansion 8.Behind liquid injection hole 10 ' injection liquid (oil), hydraulic pressure is to tightly the active force of chock is greater than the power to clamping expansion head, and hydraulic pressure is high more, and the clamping force that tight chock is expanded head (just producing stainless steel tube indirectly) to clamping is big more.
The processing method of this stainless steel nest silk bobbin is, extruding clamps the tight chock 10 of blocking device to stainless-steel pipe 6 heads with mould, its liquid injection hole UNICOM hydraulic cylinder, hydraulic cylinder is the fluid injection body in die cavity 14, adopt hydraulic pressure to pressurizeing in the stainless steel tube, make stainless steel tube produce the expansion injection moulding at 4 positions, mould bulging end cap chamber, the stainless steel tube behind the injection moulding (as shown in Figure 2) has expansion joint 15, the annular of expansion joint being carried out symmetry is cut apart, and makes nest silk bobbin 16.
The processing mould and the processing method technology of stainless steel nest silk bobbin of the present invention also can be used for producing in the processing of other products such as coil corner bracket.
