The invention aims to provide a multiwire in hand type automatic terminal crimping 
machine which is rapid in speed, high in efficiency, low in 
failure rate and convenient to assemble and debug, the multiwire in hand type automatic terminal crimping 
machine comprises a stepping motor, an air cylinder, a clamping wire chuck, a peeling knife group and a terminal crimping 
machine, the machine is divided into eight portions of a 
wire cutting peeling portion, a wire feeding 
station rotating portion, a clamping wire peeling displacement portion, a clamping wire displacement portion, a wire end length adjusting portion, a clamping wire twisting portion, a terminal crimping forming portion and a wire end 
soldering tin portion, multiple wires are fed simultaneously, the wires are 
cut by a medium 
cutting knife group firstly, a front peeling knife group and a rear peeling knife group are composed of a plurality of blades, thereby multiwire simultaneous peeling can be achieved, and the peeling is simultaneously performed at two ends of a wiring harness.
