Description
Technical field
The present invention is the manufacture method about foldable tool, refers in particular to the tool heads part processing method in foldable tool。
Background technology
The prior art of tradition foldable tool spanner is process the bar using end in spanner through one end plus bending processing procedure straight forming。Wherein this body section of bar such as is at back gauge or the circle, forms, what processing spanner used end, the coaxial turnning and milling processing and forming that collocation is general, it is possible to possess with low cost and mass-produced manufacture advantage。But, supplied materials, except having the length that spanner uses, also must be contained bending and molding group and set the length that end is suitable so that materials cost remains high and group sets end volume heaviness, inconvenient to carry。
Prior art M299063, D117670, D132239, M336113 disappearance flatness and light-weighted consideration to tradition foldable tool spanner processing procedure, the use that is made as of foldable tool spanner is squeezed shape bar turn-milling cutting and is used end and use to hole/be milled into tail end group apertured and size, is effectively reduced foldable tool spanner in the consumption that makes of material and forms this decline。But, wherein the foldable tool spanner size of portion size for the consistent planarization met in foldable tool on assembling and avoids excessive group to set end volume and weight, crowded shape must be used especially to take out the unequal-sided rectangular cross section bar of line, wherein carry out using when shaping of end, due to (A) bar section moulding inequilateral and with the volume differences of (B) preformed small size spanner and body dimension from very big。Add trade union and cause that the concentric shafts machining lathe milling machine of conventional process makes wherein two side sections and has the phenomenon generation heavily cut, tool sharpening easily crumbles, situation above will be avoided can only to reduce each depth of cut, have increase processing number of times and process time。
No matter above which kind of way, all can cause that cost remains high with fraction defective。
D132239 again, more little in the machining tool area of bed of non-equilateral rectangular body, upper and lower both sides turnning and milling is to the consume of cutter or to add man-hour more long。
Furthermore, I383868 is for above-mentioned existing lightweight foldable tool spanner technology, also point out end (group sets end) and omit too much volume as effective loss of weight, and be only general tradition and squeeze shape and take out the structure of line body and have and bear hypodynamic problem, especially the thick more thin small size foldable tool spanner situation of tail end meat is more obvious, and then propose to use relevant plastotype deformation processing procedure to promote body construction density, also it is unlikely to lose structural rigidity after removal group sets the heavy volume of end。Need first by dnockout again (impact forging) the processing procedure molding of cylinder steel material for the method, cause that blank body is accumulated suitable residual concentrated stress in this processing procedure and causes hardening。It is thus desirable to annealing softening just can carry out pressing and external form milling sets end dimensional thickness and final size to required group。Though this processing procedure can obtain preferably structural rigidity through the plastic deformation processing procedure such as dnockout (impact forging) and pressing while reducing volume。But, the annealing process that elimination inside workpiece adds through forging the machining stress remained can be likely to produce the risk of decarburization in a large amount of production, causes instrument to be unable to reach the doubt of the due intensity of material after subsequent heat treatment is hardened。And the dnockout wherein used (impact forging) and tediously long procedure for processing make cost costly on the contrary。
Additionally to increase bending side pressure before proposing tradition bending processing procedure flat and remove the processing procedure such as clout for prior art I369274, and it can overcome I383868 cost intensive and the tediously long shortcoming of processing procedure, and reaches same demand。But though the density of texture that plastotype deformation processing procedure effectively lifting body and the group flattened set end makes rigidity promote, but the residual stress produced after flattening can cause bending end to produce hardening phenomenon in the course of processing, carry out in the Forging Process of high plastic deformation's amount subsequently, bar is susceptible to fracture or cannot the processing procedure defect of bending, and then affect the problems such as the stability on producing, and processing procedure shortening die life。
From the above-mentioned prior art developed for conventional art, can summarize and extremely to be developed go out to have the lightweight foldable tool spanner processing procedure of following features: the bar body of (1) supplied materials such as needs to possess at the shape facility of back gauge or circular cross section, arrange in pairs or groups traditional concentric turn-milling cutting, it is possible to effectively reduce process time and increase cutter life。(2) density of material can be effectively increased through suitable plastic deformation processing procedure and promote body construction rigidity, but follow-up difficulty in processing should not be caused to increase improve with mortality adding the big plastic deformation processing procedure of deflection。(3) avoid the annealing process being added with decarburization risk to keep the stability on processing procedure。(4) group sets end and avoids using tradition bending and molding processing procedure, it is possible to effectively reduces volume weight, and reduces material cost。
Summary of the invention
