Description
Technical field
The present invention relates to the forming method of a kind of ratchet wrench main body parts so that the making of ratchet wrench main body parts, not only can significantly reduce work flow, and material deterioration inside can be greatly reduced, and then reach effectively to reduce the benefit of cost of manufacture.
Background technology
nullRefer to Fig. 1、Fig. 2，The molding mode of the body of current ratchet spanner，On a solid iron material, in the way of forging, mainly mold the embryo body of body 10，Then in the way of plane lapping，The cephalic par end face of the embryo body of this body 10 and bottom surface are ground respectively the first plane 11 and the second plane 12，In order to make the cephalic par of the embryo body of this body 10 can assemble the assembly of ratchet device，Then in the way of milling machine Milling Process，The first storage tank 13 and the second storage tank 14 is milled out in the cephalic par of the embryo body of this body 10，For assembling the ratchet ring of ratchet device and clip tooth assembly (graphic do not show) respectively，The perforation 15 of through second storage tank 14 is molded again in the way of boring，For the reversing switch (graphic do not show) wearing ratchet device，Then the embryo body of this body 10 is carried out heat treatment again and surface finish processes，Finally bestow electroplating processes again，Can the whole body 10 completing to produce ratchet spanner.But, the molding mode of the body of this ratchet spanner, there is following scarce fraud:
1, work flow is numerous and diverse: owing to being make with solid iron material, therefore after forging molding goes out embryo body, it is necessary to carry out the operations such as plane lapping, Milling Process and boring, be just provided that the assembly space of the assembly of ratchet device, make whole work flow very numerous and diverse, cause that cost of manufacture is too high.
2, material is excessively consumed: owing to being make with solid iron material, therefore not only go out stage of embryo body at forging molding and to remove substantial amounts of material, and in the process of the operation such as Milling Process and boring, it is also intended to excavate substantial amounts of material, make whole work flow consume very much material, cause that cost of manufacture is too high.
In view of this, the present inventor is engaged in research and development and the making experience of relevant industries then for many years with it, further investigate for current problem encountered, through long-term endeavour research with study, eventually grind the forming method creating a kind of ratchet wrench main body parts, to be effectively improved the shortcoming of background technology, this is the design aim of the present invention.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to: the forming method of a kind of ratchet wrench main body parts is provided, solve that the work flow that prior art exists is numerous and diverse, the excessively problem such as consume material.
For achieving the above object, the technical solution used in the present invention is:
The forming method of a kind of ratchet wrench main body parts, it is characterised in that include:
First plate forming step: be utilize stamping forming mode to mold the base with cephalic par on this first plate, and make the cephalic par of this base stamp out at least one perforation, and make the periphery of this base be formed with the limit wall raised up, form open accommodation space in this limit wall；
Second plate forming step: be mold cover plate on this second plate；
Installation step: be covered on this base by this cover plate, makes this cover plate and this base be fitted to each other, and closes this accommodation space formed in the limit wall of this base；
