Embodiment Construction

[0038] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention. It should be noted that in the drawings of this embodiment, the words "SBZZ" and "SHIBAZI" shown are only used to illustrate that the handle of the knife handle has inset fonts, which can increase the anti-slip effect, and are not used for Protect the specific content and meaning of fonts, and are not used to designate product trademarks.

[0039] Handle embodiment

[0040] combine Figure 1-4 , The invention provides a knife handle for welding on the knife body.

[0041] The knife handle 100 is a hollow structure, and the head end of the knife handle 100 is a tapered portion, and the end of the knife handle 100 is encapsulated with a handle plug 110 . The tapered part along the axis of the handle 100 has a smoothly connected outer convex area 101, inner concave area 102 and straight extension area 103, see figure 2 and 4 , in orde...

Abstract

The invention relates to a welding process for cutter handles, in particular to a cutter handle and a welding method for the cutter handle and a cutter body. The head end of a cutter handle body is in a gradual contraction tapered portion, and a handle plug is encapsulated at the tail end of the cutter handle body; the tapered portion is provided with an outer convex area, an inner concave area and a straight stretching area in sequence along the axis of the cutter handle, and the outer convex area, the inner concave area and the straight stretching area are connected smoothly; a positioning groove concaved along the axis of the cutter handle is formed in the center of the handle plug. The welding method includes the steps that the cutter body is inserted into the cutter groove of the cutter handle, thermal treatment, welding and tempering heat preservation are conducted in sequence, and weld joint grinding and cutter handle surface antiskid treatment are carried out. The cutter handle solves the technical problem that the structure of a traditional cutter handle affects welding quality and welding efficiency; the technical problem that deformation is prone to occurring in a traditional welding method is solved through the provided welding method.

Description

technical field [0001] The invention relates to the field of welding of knife handles, in particular to a knife handle and a welding method of the knife handle and a knife body. Background technique [0002] Most of the head ends of the current knife handles have a tapered portion, and the tapered portion is provided with a gap for inserting and welding the knife body. [0003] Limited by the above-mentioned structure of the handle, the welding quality and efficiency of the handle are low, specifically: the edge of the tapered part is not neat, and the cutter body needs to be closed or flared before welding; the cutter body After insertion, it contacts with the notch point or line, the welding fit is poor, and it is easy to weld through; the starting point of welding cannot be accurately positioned, and the weld seam is irregular, so it is difficult to realize the subsequent grinding automation, and the irregular weld seam is only It can be ground by manual operation, and t...
