Abstract
The invention discloses a forming die for automatically regulating a thread pitch for a medical corrugated pipe. The forming die comprises a handle body, a connecting hole, a threaded hole, a placing bevel, a forming rod, a plurality of helical forming strips, cambered surfaces, a plurality of notches, and bar-shaped grooves, wherein the handle body is cylindrical, the connecting hole is formed in one end of the handle body, the forming rod is integrally arranged at the other end of the handle body, the threaded hole is formed in the side surface of the handle body, the placing bevel is formed at the connecting part of the handle body and the forming rod, the helical forming strips are arranged on the surface of the forming rod, the surfaces of the helical forming strips are the cambered surfaces, extending surfaces are on the same cylindrical surface, the notches are formed in each helical forming strip, and three circular holes are formed in each notch; the bar-shaped grooves are respectively formed in every two helical forming strips, and a through hole in the end part of the forming rod is communicated with the threaded hole and the circular hole. The forming die disclosed by the invention has the benefits of simple structure, convenience in manufacturing, high production efficiency, and convenience in operation, and does not need to be regulated.
Description
Technical field
The present invention relates to the technical field of medical tubes manufacturing equipment, particularly a kind of medical corrugated pipe regulates pitch mould automatically.
Background technology
Medical corrugated pipe is the bent flexible pipe that a kind of plastics are made, medical tubes connects patient and lung ventilator, Anesthesia machine, the excellent passage of cpap, medical corrugated pipe manufacturer is wound in delivery mold by the plastic foil of injection moulding place, after be around on plastic foil by spiral for plastic strip rounded for cross section while winding plastic film again, carry out cooling to export, but the mould of traditional this type of bellows of manufacture is in order to manufacture the bellows of different spacing plastic strip, need the mould of manual adjustments merogenesis individual, need skilled skilled worker just can accurately create, being applicable to manufacturing the personnel produced measures few, and the time spent in adjustment is many, production efficiency reduces.
Summary of the invention
For solving the problem, the object of this invention is to provide that a kind of structure is simple, easily manufactured, production efficiency is high, without the need to carrying out regulating, easy to operate medical corrugated pipe regulates pitch mould automatically.
For achieving the above object, technical scheme of the present invention:
A kind of medical corrugated pipe regulates pitch mould automatically, comprise handle body, connecting hole, screwed hole, place inclined-plane, curved lever, the shaping bar of helical form, cambered surface, notch, bar-shaped trough, described handle body is cylindrical, handle body one end has connecting hole, other end integral type is provided with curved lever, handle body side surface has screwed hole, handle body and curved lever joint are for place inclined-plane, curved lever surface is provided with the shaping bar of some helical forms, the shaping bar surface of helical form is cambered surface, and extended surface is on the same face of cylinder, the shaping bar of every bar helical form has some notches, notch all has three circular holes, be bar-shaped trough between the shaping bar of helical form between two, the through hole of curved lever end and screwed hole, circular hole is communicated with.
As preferably, described handle body and curved lever are made of metal.
As preferably, described notch is lower than cambered surface surface.
As preferably, in described bar-shaped trough, be all placed with the swingle of rotation.
Beneficial conditions of the present invention is: structure is simple, and easily manufactured, production efficiency is high, without the need to regulating, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the structural representation of connecting hole on handle body of the present invention.
Detailed description of the invention
As Fig. 1, shown in 2, a kind of medical corrugated pipe regulates pitch mould automatically, comprise handle body 1, connecting hole 2, screwed hole 3, place inclined-plane 4, curved lever 5, the shaping bar 6 of helical form, cambered surface 7, notch 8, bar-shaped trough 10, described handle body 1 is cylindrical, handle body 1 one end has connecting hole 2, other end integral type is provided with curved lever 5, side has screwed hole 3 to handle body 1, handle body 1 and curved lever 5 joint are for place inclined-plane 4, curved lever 5 surface is provided with the shaping bar 6 of some helical forms, shaping bar 6 surface of helical form is cambered surface 7, and extended surface is on the same face of cylinder, the shaping bar of every bar helical form 6 has some notches 8, notch 8 all has three circular holes 9, be bar-shaped trough 10 between the shaping bar 6 of helical form between two, the through hole of curved lever 5 end and screwed hole 3, circular hole 9 is communicated with.Described handle body 2 is made of metal with curved lever 6.Described notch 8 is lower than cambered surface 7 surface.The swingle of rotation is all placed with in described bar-shaped trough 10.The connecting hole 2 of handle body 1 one end of the present invention is for being connected and fixed use, the swingle of rotation is all placed with in bar-shaped trough 10, and swingle is connected on the Connection Block at placement inclined-plane 4 place, Connection Block controls the rotary speed of swingle, when manufacturing bellows, the plastic foil that one end exports is around on curved lever 5, and simultaneously on swingle, the plastic strip that meanwhile other end exports is around in plastic film, by the rotation of swingle, the mode that the bellows manufactured rotates is exported, thus the bellows fashion formed is that plastic strip spiral wrap is at plastic sheet surface, by the rotating speed of swingle on control connection seat, plastic strip can be manufactured and be wound around the different bellows of gradient, operation is very easy, without the need to manual adjustments, by passing to cooling fluid in screwed hole 3, curved lever 5 can be cooled, and cooling fluid makes bellows carry out fast cooling shaping by circular hole 9, screw type shaping bar 6 has some notches 8, make bellows can not stick in cambered surface 7 when manufacturing and exporting, cambered surface 7 makes to manufacture the bellows inner wall smooth obtained.
