The invention belongs to the field of cutter machining equipment, and relates to a cutter handle shaping device and a cutter handle shaping method. The problems that in the prior art, due to split type operation and manual transfer, temperature drop is too large, and the shaping quality is not stable are solved. The device comprises a cutter conveying assembly, a heating assembly and a pressing assembly. A first position for heating and a second position for pressing are sequentially arranged on a guide rail of the cutter conveying assembly. The cutter conveying assembly is used for driving the cutter to be transferred from the first position to the second position for press-fit shaping after heating is completed. The heating process and the pressing process are integrated on the same automatic platform, the process transfer time is shortened, temperature drop of the cutter handle in the transfer process is restrained, and therefore the quality stability and consistency of final products are improved.
