Example Embodiment

[0034] Such as figure 1 with figure 2 As shown in the figure, the hair clipper 1 includes two scissors halves 2 and 3, which are pivotally connected to each other through a lock pin 4 as a medium. The scissors half 2 includes a ring portion 21, a handle portion 22, a scissors blade portion 23 and a blade 24. In addition, a knife-edge stop 25 and a finger strut 26 can also be arranged on the ring 21. The scissors half 3 includes a ring portion 31, a handle portion 32, a scissors blade portion 33 and a blade 34.

[0035] Refer to below Figure 3A-3C Taking the scissors half 2 as an example to illustrate the manufacturing steps of the hair clipper 1, the manufacturing steps of the scissors half 3 are similar to this.

[0036] First, the two scissors halves 2, 3 are provided and processed in its well-known traditional way. Specifically, at the beginning of the operation, while cutting the thread and drilling the threaded hole for the lock pin 4 in the form of a bolt on the assembly ...

Abstract

The invention relates to a method for manufacturing hair clippers (1), wherein the scissors blades (23, 33) are preformed with a predetermined degree of curvature from a blank in a direction away from the blade. This is followed by a welding step of welding hard metal material in the form of weld beads to the respective surfaces of the scissors blades (23, 33) facing each other to form the blades (24, 34), wherein the above-mentioned Prebending is counteracted during welding due to thermal influences. The weld bead is then ground to form the cutting edge (24, 34) and the scissors halves (2, 3) are pretreated and hard quenched. Then the hair clippers (1) are fastened and assembled to the assembled state. The invention also relates to a hair clipper (1) having the above-mentioned construction. Since the blades (24, 34) are the main material over the entire thickness of the scissors' blades (23, 33), even several repeated regrinding or reprocessing of the hair clippers (1) will not result in any loss of functionality .

Description

technical field [0001] The present invention relates to a method of manufacturing hair clippers. Background technique [0002] Scissors traditionally consist of two halves hingedly interconnected by a locking pin, and the two scissor halves and their blades are usually formed from stainless steel or a rust resistant steel alloy. However, such scissors present the disadvantage of losing their sharpness in the area of ​​the blade after a relatively short period of use. The technique of applying a hard metal layer in the region of the cutting edge is also known for this purpose. The service life of the scissors can thus be considerably extended and the blades will remain sharper for longer due to the strength of the hard metal. In contrast, however, hard metals are relatively brittle, making the manufacturing steps to assemble the clippers more difficult to perform than scissors with traditional steel alloy blades. Excessive machining and the resulting deformation can create...
