Description
Technical field
The present invention relates to a kind of thread tapper for hole processing.
Background technology
In mechanical processing process, the hole processing link that is absolutely necessary, at present, conventional processing method is for several below:
1. manual tapping;
2. carry out tapping with numerical control device or boring machine;
3. tapping machine or the tapping machine changed a social system by bench drill carry out tapping.
Above-mentioned manual tapping efficiency is low, precision is not high, is only applicable to single-piece or small lot batch manufacture.This method is ubiquity in individual workshop or the small enterprise below 500 people.
Above-mentioned numerical control device or boring machine tapping, be usually used in the processing of those high-precision products, and this method cost is higher, efficiency is low.Moreover numerical control device investment is large, so seldom adopt in screw thread processing within Chinese territory.
Above-mentioned tapping machine (device) tapping mode, equipment investment is few, efficient, quick, requires lower to employee quality.So generally adopted by large and medium-sized enterprise.But this tapping method has that a shortcoming---power consumption is high, and maintenance cost is high.Analyze the tapping process of this tapping machine, motor will complete following action:
Motor is being rotated in the forward after tapping action, realizes reverse stop by touching travel switch, and then reverse rotation is released.
By the known motor of electrotechnics general knowledge starting current be rated current 6～8 times, can be higher in the time of reversal connection stop, data are learnt according to the relevent statistics, the power of motor of tapping machine is common driller 3～6 times, power consumption is multiplied.The simultaneously frequent commutation of motor makes it the life-span and greatly reduces, and average life span only has 300～500 hours, and having arrived hot summer electrical machinery life can be lower.Cause maintenance cost significantly to increase, so the frequent commutation of motor has just become its fatal weakness, avoid motor frequently to commutate into problem demanding prompt solution.
As can be seen here, be necessary existing tapping machine to further improve.
