Description

A kind of helical bellows tracking fluting perforating device

Technical field

Field of machining is the utility model is related to, particularly a kind of helical bellows tracking grooving apparatus.

Background technology

At present, known helical corrugation tubing groover includes some groups of cutting tools on same circumference, this A little cutting tools can be fed or exit, these cutting tools to helical bellows center position under the drive of external motivating force The characteristics of motion it is identical with motion mode, each cutting tool fed every time to center position or when exiting it is always synchronous, often enter To once, just a groove, the fluting quantity of circumferencial direction and the quantity of cutting tool are opened to helical corrugation tubing excircle direction Unanimously, but these apparatus structures are more complicated, it is necessary to more driving equipments, high energy consumption, slotting position are relatively fixed, Wu Fayan Helical bellows spiral tracking fluting；Multiple holes are beaten on circumference, multiple cutting tools circumferentially act on simultaneously, increase spiral The radial force of bellows, make helical bellows deformation larger；When axially opening multiple holes simultaneously, each cutting tool is axially grooved Quantity is consistent with the number of cutters that cutting tool is filled, porous linearly to be arranged on helical bellows after pore-forming, reduces spiral shell Revolve the intensity of bellows；It is consistent with helical bellows pitch or helical pitch per the distance between two neighboring cutter, the is opened every time Before one groove, the central alignment of blade and helical bellows trough will be allowed to knife, when opening second groove, by leading first Draw machine by helical bellows to front haulage, hauling machine needs to be separately provided outside grooving apparatus, and structure is not compact, volume compared with Greatly, also there are the cramped construction that helical bellows forward drive is set on grooving apparatus, such as Chinese patent in the prior art CN102452099 discloses one kind and slotted in worm-type plastic corrugated pipe grooving machine, the conveying of plastic film capicitor by being fixed on Worm screw curve on knife knife bar is completed, and slotting function installed in an alloy cutter head of worm screw curve end by realizing, such as Fruit needs the circumferencial direction in material corrugated pipe to open N bar grooves, and the pitch of worm screw curve is just designed as plastic corrugated pipe crest section Away from N-1/N times, worm screw curve engages with the crest of plastic corrugated pipe, and when knife bar often rotates a circle, plastic corrugated pipe is in snail One pitch of advance, i.e. plastic corrugated pipe proceed to next trough by being currently located trough under the promotion of bar curve, install Alloy cutter head in worm screw curve end is slotted once to being currently located trough, and the alloy cutter head installed in worm screw curve end hangs down Directly in the axis of plastic corrugated pipe, to ensure that blade does not move axially in the section plastic corrugated pipe of cutting, with knife bar Rotation, plastic corrugated pipe constantly produces axis movement, and blade slotted one by one to each trough.This mode conveys Plastic film capicitor interacts to realize there is mutual work between worm screw curve and crest by worm screw curve with crest Firmly larger, when particularly opening multiple grooves simultaneously, the reaction force of cutter is more increased between worm screw curve and crest Interaction force, so as to easily deform knife bar, the active force of worm screw curve and crest is influenceed, reduce conveying quality, make fluting Deviation occurs for position, further influences fluting quality；By worm screw curve and the volume constraint of knife bar, for the ripple compared with pipe with small pipe diameter Circumferentially worm screw curve and knife bar limited amount are managed, so as to limit the quantity of fluting, can not also realize that tracking is slotted；And Plastic film capicitor using directive wheel Clamping Center positioning and alloy cutter head perpendicular to plastic corrugated pipe axis two ways come Prevent plastic film capicitor displacement, cutter and otch from positioning, but complicated, continuous operation inconvenience, poor accuracy.

In the prior art, sense counter favorably also is carried out to helical bellows trough to realize conveying with photoelectric sensor switch Distance controlling, to ensure to carry out whole piece helical bellows the positioning of continuously fluting and slotting position, because conveying is drawn Machine has driving error and motional inertia, plus photoelectric sensor switch sense counter error often result in slotting position produce it is very big Deviation, prevent slotting position from groove to be even opened in the crest of plastic corrugated pipe positioned at the center of plastic corrugated pipe trough On, generate a large amount of of helical bellows and scrap.In order to overcome above mentioned problem, the use also having in the fluting machinery of prior art Mechanical device positioning substitutes optoelectronic induction to position, during fluting, the crest of these mechanical positioners and helical bellows or Trough is in contact, the position that helical bellows is fixed and is positioned at the position for needing to slot where grooving tool, Ran Houkai Groove instrument carries out fluting action, after a slotted eye is cut, it is necessary to separate above-mentioned mechanical positioner with helical bellows, so Afterwards with hauling machine by helical bellows to axial traction, in moving process, positioner contacts progress with helical bellows again The problem of fixed and positioning, grooving tool carry out fluting action, complete next slotted eye again, and this positioning method is present be In whole position fixing process, positioner is constantly separated and contacted with helical bellows, because conveying hauling machine has driving error And motional inertia, mechanical positioner is as the influence of machining accuracy and installation accuracy, so as to cause the position positioned every time Generation deviation is put, precision is low, has a strong impact on fluting quality.
