Description
[technical field]
The utility model belongs to the copper pipe internal thread forming technical field, relates in particular 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 the rotary press modelling internal thread, copper pipe uniform motion forward under the pulling force effect, the spin roll extrusion copper pipe outer surface of while High Rotation Speed, copper pipe inside is connected to the screw thread core print automatic rotating on the floating core head, make copper pipe be in approximate at a high speed oblique transverse rolling state, the teeth groove on the screw thread core print makes the copper pipe inwall become profile of tooth, forms inner screw thread copper pipe.
But present copper pipe internal thread forming spinning machine all is to be undertaken spinning amount size is adjusted, controlled by the annular gasket that replacing is arranged on the different-thickness between adapter sleeve and the revolving sleeve, adopts this structure to have following problem:
When 1, adjusting grammes per square metre, at first spinning head (being whole revolving sleeve) must be unloaded, load onto the pad of desired thickness, and tighten spinning head; Then the debugging grammes per square metre of driving if improperly also must again spinning head be unloaded the pad that is loaded on another thickness, and tightens spinning head, and the debugging grammes per square metre of again driving, so frequently repeatedly, until adjust accurately; Technique is very loaded down with trivial details, loses time, efficient is low, and shunts each time and all can produce the waste material of shunting, general accent once can produce 10 kilograms, need to just grammes per square metre can be mixed up for two to three times, namely transfer 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, at present the spacer thickness used of workshop is that 0.03 millimeter at every interval arranges a specification, 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 satisfy the demand of production scene, and modal is that to add " 0.03 millimeter " grammes per square metre large, and it is little to subtract " 0.03 millimeter " grammes per square metre, namely need: just do not have suitable pad when " 0.02 millimeter with 0.01 millimeter ", can't realize continuous adjusting of " Mick is heavy " size.
When 3, after pad is changed in the production scene, it being locked, 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, and when locking force too small (pine of namely locking), grammes per square metre then increases relatively, assembly precision is low, can't Measurement accuracy, greatly reduce yield rate; And a great problem especially for new operator needs constantly exercise and experience accumulation just can grasp locking force, has directly affected output and the quality of product, reaches the raising that affects the finished product rate.
In addition, the lubricating system of existing copper pipe internal thread forming spinning machine is the oil-feed of advancing, and throw away by aperture on the revolving sleeve (being generally the hole of 9 ∮ 4mm), but lubricants capacity is larger, 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, the dynamic balancing effect is bad, at steel ball copper pipe is carried out spinning and often be accompanied by and beat, it is different to produce the copper pipe high difference of same axial chi and surface indentation width, and impact is produced by flute profile and copper pipe outer surface quality.
