Description
Technical field
The present invention relates to a kind of current supply circuit, particularly relate to a kind of inferior current supply circuit that is used for computerized numerical control sawing machine.
Background technology
Cutting machine is people's cutter sweeps commonly used when blocking or cutting off all kinds of workpiece, and existing cutting machine is divided into hand-held cutting machine and table saw substantially.Hand-held cutting machine volume is less, has a housing usually, is provided with parts such as motor in the housing, is provided with the grinding wheel as cutting tool in housing one side, and grinding wheel is moving in the driving downward modulation turn over of motor, is used for cut workpiece.The hand-held cutting machine also has a handshake part, during use, grasps the handshake part and carries out cutting operation.
The employed grinding wheel diameter of hand-held cutting machine is less, and general diameter is 100 millimeters to 200 millimeters, because the hand-held cutting machine is by user's hand-held, randomness is bigger, in case careless manipulation is easy to cause grinding wheel to break, causes personal injury.And during owing to cut workpiece, workpiece is bigger to the reaction force of hand-held cutting machine; Often need both hands to hold with a firm grip and carry out operation, need to use other clamping workpiece with 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.The table saw volume is relatively large; It has a support; Support is provided with the piece-holder assembly that is used for the clamping workpiece, and through by motor-driven grinding wheel workpiece to be processed being cut, the grinding wheel diameter that table saw uses is bigger; Normally more than 250 millimeters, be fit to the cutting large-scale workpiece.
Yet; Table saw is not suitable for cutting miniature workpiece on the contrary because the grinding wheel diameter is bigger, and cutting is difficult to realize cutting accurately during miniature workpiece; And moving before and after present cutting mechanism all can only carry out; If the processing work diameter is bigger, the process time of so this cutting mode is long, and cut surface out-of-flatness, accurate.
More than two kinds of cutting machines all do not have control circuit, so handling and security performance are not fine, in reality cutting, can't accurately cut accurate parts.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of inferior current supply circuit that is used for computerized numerical control sawing machine, can effectively improve the handling and the security performance of cutting machine, the parts that cut ratio is accurate.
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 that is used for computerized numerical control sawing machine is provided; This inferior current supply circuit that is used for computerized numerical control sawing machine comprises transformer, QF7 breaker, emergency stop switch, Switching Power Supply, auxiliary circuit A and auxiliary circuit B; Be parallel to the 220V output point of transformer after the input point of said Switching Power Supply and breaker, the emergency stop switch series connection again; 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.
Preferably, said auxiliary circuit A comprises QF8 breaker, lighting lamp circuit, water pump open circuit, oil pump open circuit, and is parallelly connected with the water pump open circuit again after said QF8 breaker and the lighting lamp circuit series connection, and then parallelly connected with the oil pump open circuit.
Preferably; Said auxiliary circuit B comprises the tight opening of valves circuit of saw band, saw band pine opening of valves circuit, saw band pressure retaining valve open circuit, feed servo brake control circuit and up-down servobrake control circuit, is between the tight opening of valves circuit of said saw band, saw band pine opening of valves circuit, saw band pressure retaining valve open circuit, feed servo brake control circuit and the up-down servobrake control circuit to be connected in parallel.
The invention has the beneficial effects as follows: a kind of inferior current supply circuit that is used for computerized numerical control sawing machine of the present invention can effectively improve the handling and the security performance of cutting machine, the parts that cut ratio is accurate.
