Description
Technical field
The present invention relates to a kind of current supply circuit, particularly relate to a kind of inferior current supply circuit for computerized numerical control sawing machine.
Background technology
Cutting machine is people's conventional cutter sweeps when blocking or cutting off all kinds of workpiece, and existing cutting machine is divided into hand-hold shearing unit and table saw substantially.Hand-hold shearing unit small volume, has a housing conventionally, is provided with the parts such as motor in housing, in housing one side, is provided with the grinding wheel as cutting tool, and grinding wheel is lowered turn in the driving of motor and moved, for cut workpiece.Hand-hold shearing unit also has a handshake part, during use, grasps handshake part and carries out cutting operation.
The grinding wheel diameter that hand-hold shearing unit is used is less, and general diameter is 100 millimeters to 200 millimeters, and because hand-hold shearing unit is by user's hand-held, randomness is larger, once careless manipulation is easy to cause grinding wheel to break, causes personal injury.And, during due to cut workpiece, workpiece is larger to the reaction force of hand-hold shearing unit, often needs both hands to hold with a firm grip and carries out operation, need to use other holding workpieces by piece-holder to be cut, or need other people that workpiece to be cut is held with a firm grip, this all makes troubles to operation, in addition, and different users's operating habit, qualification difference, also cause the stability of operation there are differences, cut quality is unstable.Table saw volume is relatively large, it has a support, support is provided with the piece-holder assembly for holding workpiece, by workpiece to be processed being cut by motor-driven grinding wheel, the grinding wheel diameter that table saw is used is larger, normally more than 250 millimeters, be applicable to cutting large-scale workpiece.
Yet, table saw is because grinding wheel diameter is larger, be not suitable on the contrary cutting miniature workpiece, and during cutting miniature workpiece, be difficult to realize cutting accurately, and the movement before and after present cutting mechanism all can only carry out, if processing work diameter is larger, the process time of so this cutting mode is long, and cut surface out-of-flatness, accurate.
Above two kinds of cutting machines all do not have control circuit, so handling and security performance are not fine, in reality cutting, cannot accurately cut accurate parts.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of inferior current supply circuit for computerized numerical control sawing machine, can effectively improve handling and the security performance of cutting machine, cuts more accurate parts.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of inferior current supply circuit for computerized numerical control sawing machine is provided, inferior current supply circuit for computerized numerical control sawing machine comprises transformer, QF7 breaker, emergency stop switch, Switching Power Supply, auxiliary circuit A and auxiliary circuit B, after the input point of described Switching Power Supply and breaker, emergency stop switch series connection, be parallel to again the 220V output point of transformer, the 36V output point of transformer is connected to auxiliary circuit A, and the output point of Switching Power Supply is connected to auxiliary circuit B; Auxiliary circuit A comprises QF8 breaker, lighting lamp circuit, water pump open circuit, oil pump open circuit, between lighting lamp circuit, water pump open circuit and oil pump open circuit, be and be connected in parallel, between QF8 breaker and lighting lamp circuit, water pump open circuit, be and be connected in series; Auxiliary circuit B comprises the tight valve open circuit of saw band, saw band pine valve open circuit, saw band pressure retaining valve open circuit, feed servo brake control circuit and lifting servobrake control circuit, between the tight valve open circuit of described saw band, saw band pine valve open circuit, saw band pressure retaining valve open circuit, feed servo brake control circuit and lifting servobrake control circuit, is and is connected in parallel.
The invention has the beneficial effects as follows: a kind of inferior current supply circuit for computerized numerical control sawing machine of the present invention can effectively improve handling and the security performance of cutting machine, cuts more accurate parts.
