Description
[technical field]
The invention belongs to copper pipe internal thread forming technical field, particularly relate to a kind of forming of internal thread copper pipes spinning apparatus.
[background technology]
At present, inner screw thread copper pipe is a kind of efficient heat conducting tube, and its heat exchange efficiency is far above smooth wall pipe, but the moulding process more complicated of internal thread, generally comprise floating core head draw dial, rotary press modelling internal thread and sizing sky draw; Wherein, when carrying out rotary press modelling internal thread, copper pipe uniform motion forward under a stretching force, the spin roll extrusion copper pipe outer surface of High Rotation Speed simultaneously, the inner screw thread core print be connected on floating core head of copper pipe rotates automatically, make copper pipe be in approximate oblique transverse rolling state at a high speed, the teeth groove on screw thread core print makes copper pipe inwall become profile of tooth, forms inner screw thread copper pipe.
But present copper pipe internal thread forming spinning machine is all that the annular gasket by changing the different-thickness be arranged between adapter sleeve and revolving sleeve carries out adjusting spinning amount size, controlling, and adopts this structure to there is following problem:
When 1, adjusting grammes per square metre, first spinning head (i.e. whole revolving sleeve) must be unloaded, load onto the pad of desired thickness, and tighten spinning head; Then driving debugging grammes per square metre, also again must unload the pad being loaded on another thickness if improper, and tighten spinning head by spinning head, and debugging grammes per square metre of again driving, so frequently repeatedly, until adjustment is accurately; Technique is very loaded down with trivial details, loses time, efficiency is low, and shunts each time and all can produce waste material of shunting, general tune once can produce 10 kilograms, need just grammes per square metre to be mixed up for two to three times, namely adjust a grammes per square metre to want 10 ~ 30 kilograms of waste materials of shunting, have a strong impact on output and yield rate.
2, the spacer thickness in workshop arranges a specification at interval of 0.03 millimeter at present, from 4.70 millimeters until 5.50 millimeters, and 28 ranks altogether, the thickness difference between each pad is 0.03 millimeter, and pad quantity is many, and cost is high; Even so, this pad can not meet the demand of production scene, and modal is add " 0.03 millimeter " grammes per square metre greatly, subtracts " 0.03 millimeter " grammes per square metre little, namely need: just there is no suitable pad time " 0.02 millimeter with 0.01 millimeter ", the continuous adjustment of " Mick weight " size cannot be realized.
When 3, it being locked after pad is changed in production scene, the control of locking force is a very crucial problem, when locking force excessive (tension of namely locking), grammes per square metre then reduces relatively, on the contrary, when locking force too small (pine of namely locking), grammes per square metre then increases relatively, assembly precision is low, cannot Measurement accuracy, greatly reduces yield rate; And, for a great problem especially new operator, need constantly exercise and experience accumulation just can grasp locking force, directly affects the seed output and quality of product, and affect the raising of finished product rate.
In addition, the lubricating system of existing copper pipe internal thread forming spinning machine is advance oil-feed, thrown away, but lubricants capacity is larger by aperture on revolving sleeve (being generally the hole of 9 ∮ 4mm), throw away large gauging and can bring very large resistance to motor, affect electrical machinery life; And the dynamically balanced major effect point of motor is the weight that front end is subsidiary, dynamic balancing effect is bad, carry out spinning often along with beating at steel ball to copper pipe, the same axial chi height of generation copper pipe is different and surface indentation width is different, and impact is produced by flute profile and copper pipe outer surface quality.
[summary of the invention]
