Description
Technical field
The utility model relates to seamless copper pipe processing technique field, in especially a kind of seamless internal thread copper pipe molding process, and the protector of spinning mold.
Background technology
Seamless internal thread copper pipe is widely used in refrigeration industry, and inner screw thread copper pipe manufacturing technology is constantly brought forth new ideas, and being widely used at present seamless internal thread copper pipe process technology is planet ball rolling method.Be with fluted external screw thread tooth core print inner placement of copper pipe, the outside planet ball rolling method extruding adopting with steel ball.
Existing seamless internal thread copper pipe process principle is:
As shown in Figure 2, light face copper pipe 12 inside will be placed on the core bar 5 of supporting-core 1 and screw thread core print 6, in the outside of light face copper pipe 12 and screw thread core print 6 correspondences, adopt the planet ball spinning apparatus 7 of High Rotation Speed to push, the inwall copper material of light face copper pipe 12 embeds the groove of screw thread core print 6.Through the drawing of draw-gear 10, be with female copper pipe to depart from screw thread core print 6, this process processes inner screw thread copper pipe 8.Because seamless internal thread copper pipe 8 is that automatic online is produced continuously, approximately 10000～20000 meters of single pipe lengths, spinning apparatus 7 is to rely on high-speed electric expreess locomotive to drive to do circumference High Rotation Speed, approximately 24000～35000 revs/min of rotating speeds.When enhanced stretch resistance is excessive, supplied materials light face copper pipe 12 flat tubes and light face copper pipe 12 be while the defect such as ftractureing, cause sometimes the disconnected pipe of inner screw thread copper pipe 8, now rely on the reaction force that is compressed in location plate washer 4 springs 13, supporting-core 1, core bar 5 and screw thread core print 6 are exited to the processing district spinning apparatus 7 of High Rotation Speed, break to prevent that thread core 6 and spinning apparatus 7 from colliding with each other.Spring 13 plays the protective action of mould.
The shortcoming of this device is:
1, the protection of mould is to rely on spring pressurized to produce strain, and in the time that inner screw thread copper pipe is broken, mould is ejected processing district by the reaction force that spring produces, to play mould protection effect.But in whole production process, spring applies reaction force to die holder device always, cause inner screw thread copper pipe enhanced stretch resistance large, in production process, have that the frequency broken is high, pulling rate is low and size wild effect.Especially, while producing super large helical angle and tall and thin teeth internal screwed copper tube, this phenomenon is comparatively outstanding.As adopting the spring that elastic force is less, mould cannot normally eject Gong Jia district sometimes.
2, owing to being to adopt spring to realize mould and exit processing district, but equipment is so in running order, needs workman to shut down, and shuts down and causes not in time unnecessary waste.

The technical problems to be solved in the utility model is: in order to solve problems of the prior art, the utility model provides a kind of cylinder type forming of internal thread copper pipes mould protector, by electric system control cylinder action, make die sleeve reach the object of forward and backward movement, in automatic online continuous flow procedure, this device low-disturbance power, product size is stable, can not cause greatly disconnected pipe phenomenon because of reaction force, can be because the too small mould of reaction force cannot normally exit processing district yet, cause mould to damage.
The utility model solves the technical scheme that its technical problem adopts: a kind of cylinder type forming of internal thread copper pipes mould protector, comprises
Bracing or strutting arrangement, described bracing or strutting arrangement comprises positioning baffle and die sleeve, described die sleeve be arranged on positioning baffle left side, and can be with respect to positioning baffle to left movement,
Support bar, described support bar comprises core bar, and is fixedly installed on supporting-core and the screw thread core print at described core bar two ends,
Spinning apparatus and draw-gear;
Described bracing or strutting arrangement, spinning apparatus and draw-gear set gradually from left to right, and described support bar is arranged between bracing or strutting arrangement and spinning apparatus, and the position of described supporting-core is corresponding with die sleeve, and the position of described screw thread core print is corresponding with spinning apparatus,
Described die sleeve peripheral hardware is useful on the oil cylinder of controlling die sleeve side-to-side movement, between described spinning apparatus and draw-gear, is provided with photoelectric sensor, and described photoelectric sensor is connected with oil cylinder signal.
When in production process, because enhanced stretch resistance is large, supplied materials light face copper pipe flat tube and light face copper pipe have the defects such as cracking, and cause when inner screw thread copper pipe breaks pipe, signal is passed to forming machine electrical apparatus control system by photoelectric sensor, control system control oil cylinder backward movement, shrinks back out die sleeve, supporting-core, core bar and screw thread core print, mould separating spinning apparatus machining area, avoid screw thread core print and high-speed rotary pressure device mutually to break, play mould protection effect.
Concrete, described bracing or strutting arrangement also comprises supporting die, described supporting die is arranged on die sleeve inside.
Concrete, described spinning apparatus is planet ball spinning apparatus.
The beneficial effects of the utility model are: a kind of cylinder type forming of internal thread copper pipes mould protector that the utility model provides, by electric system control cylinder action, make die sleeve reach the object of forward and backward movement, in automatic online continuous flow procedure, this device low-disturbance power, product size is stable, can not cause greatly disconnected pipe phenomenon because of reaction force, can be because the too small mould of reaction force cannot normally exit processing district yet, cause mould to damage; Photoelectric sensor separately sends signal to equipment electrical apparatus control system, and control appliance autostop reduces unnecessary waste.
