The outer hexagon machining device is a self-designed machining device in the practice process and is simple in structure and low in cost, most importantly, the defects generated by a traditional machining process can be overcome, and the production efficiency and the product quality can be improved.
Description
Technical field
The invention belongs to field of machining, particularly to a kind of outer six side's processing dresses of stainless steel hexagon-headed bolt head
Put.
Background technology
In the mechanical process technique of outer six sides of existing stainless steel hexagon-headed bolt head, conventional process is
Using blanking method, socket cap is cut into six sides, after the completion of part of the upper die goes downwards to die contact workpiece and is punched, waste material is simultaneously
Without departing from workpiece, there is also about 0.3mm～0.5mm and be connected with former workpiece, when up when part of the upper die, workpiece is up with die,
Operator puts down a workpiece again, subsequent part of the upper die again second descending, last time without departing from workpiece bottom with newly put on workpiece
End contact, by recoil strength by a upper workpiece ejection die, thus completes the trimming processing of a workpiece；But, this side
Method is only feasible to carbon steel；Cut bar portion during stainless steel bolt can bend.Reason is that the ejecting force of a workpiece on next workpiece top is too big,
Workpiece bar portion is made to bend deformation.
Content of the invention
It is an object of the invention to provide a kind of not only can improve production efficiency but also can guarantee that the stainless steel turret head of product quality
The processing unit (plant) of bolt head six side.
A kind of outer six side's processing unit (plant)s of stainless steel hexagon-headed bolt head, it includes：Lower template, lower fixed seat, lower mold core,
Die socket, backing plate, left guide pillar, gripper shoe, left guide pin bushing, cope match-plate pattern, die shank, spring, dnockout block, right guide pin bushing, right guide pillar, clamp screw
Nail one, die, holding screw two；Described lower fixed seat is fixed by screws in middle part in lower template, and lower mold core passes through clamp screw
Nail two is fixed on the middle part of lower fixed seat；Described die socket, backing plate, gripper shoe, cope match-plate pattern overlap successively, by screw
Tighten together；Left guide pillar, left guide pin bushing and right guide pin bushing, right guide pillar are symmetricly set between lower template and cope match-plate pattern；Spring is arranged
In gripper shoe, die shank be arranged on cope match-plate pattern central part and with cope match-plate pattern interference fit；Under dnockout block is arranged in gripper shoe
Portion；Die is located at the centre of die socket, and is tightened together with die socket by holding screw one.
Described lower mold core top is six side's step shapes.
The present invention is a kind of processing unit (plant) that technical staff's designed, designed in practice process goes out, and is not only simple in structure, and becomes
This is cheap, and main is to solve defect produced by conventional machining process, improves production efficiency and product quality.

Specific embodiment
Below in conjunction with the accompanying drawings the present invention is described in detail.
It is an object of the invention to provide a kind of outer six side's processing methods of stainless steel hexagon-headed bolt head, the method is passed through
Special apparatus for working is realized.
As shown in figures 1-4, the outer six side's processing unit (plant)s of a kind of stainless steel hexagon-headed bolt head, it includes：Lower template 1, under
Fixed seat 2, lower mold core 3, die socket 4, backing plate 5, left guide pillar 6, gripper shoe 7, left guide pin bushing 8, cope match-plate pattern 9, die shank 10, spring 11,
Dnockout block 12, right guide pin bushing 13, right guide pillar 14, holding screw 1, die 16, holding screw 2 17.Lower fixed seat 2 passes through screw
It is fixed on middle part in lower template 1, lower mold core 3 is fixed on the middle part of lower fixed seat 2 by holding screw 2 17.Die socket 4, backing plate
5th, gripper shoe 7, cope match-plate pattern 9 overlap successively, are tightened together by screw.Left guide pillar 6, left guide pin bushing 8 and right guide pin bushing 13,
Right guide pillar 14 is symmetricly set between lower template 1 and cope match-plate pattern 9, play the guiding role.Spring 11 is arranged in gripper shoe 7, die shank
10 central parts being arranged on cope match-plate pattern 9 and with cope match-plate pattern 9 interference fit.Dnockout block 12 is arranged on gripper shoe 7 middle and lower part.Die 16
Positioned at the centre of die socket 4, and tightened together with die socket 4 by holding screw 1.
Processing method of the present invention is lower mold core 3 top to be changed system into six side's step shapes, as shown in Figure 3, Figure 4.When upper mould
Part goes downwards to die 16 contact workpiece being punched and completes, and waste material is completely separated by upper and lower cutting edge with workpiece, and part of the upper die is up
When, workpiece is not up with part of the upper die, but stays in lower mold core 3, and operating personnel are taken out workpiece with tweezers, so completes to cut
Side.Using processing unit (plant) of the present invention processing, part bar portion does not bend, and reliable in quality is high in machining efficiency.
The technical scheme is that the outer six side's technological method for processing of stainless steel hexagon-headed bolt head, tested
Card, six square bolts processing, bar portion does not bend, reliable in quality, and uniformity is good, can be generalized to all stainless steel series of products
