Abstract
The present invention relates to one kind to use the corner bolt positioning mandril of cold headers upsetting system 12, push rod cylinder, it is made up of 1, push rod anti-rotation face 2, bolt positioning table 3, push rod positioning table 4, push rod diameter, the push rod uses the bar of the materials such as T8A, the diameter to match with former endoporus is processed into as requested, the boss that width can position is processed into close to part to be processed one end, bar portion is while mill out the plane for requiring length, former bores top wire hole, plane is withstood by jackscrew, but push rod can also move radially, and prevent push rod from rotating.By the special push rod of design in the former of first upsetting position, after first upsetting blank shaping, discharging device ejects part, lathe caliper body clamps part blank, because of Novel mandril projection, is stuck in first upsetting with part bar portion end face formation straight line groove, when clamping part fine rotation will not occur for lathe caliper body, blank is moved in smart upsetting former, is not in 12 jiaos of smart upsetting formpiston die cavity and the angular displacement problem of blank 12, so as to which Fold occur.
Description
Technical field
The present invention is new to be related to a kind of push rod, and specifically, be related to needs to limit using a kind of part of machine adding method processing
The push rod of position.
Technical background
A kind of existing 12 corner bolt, due to of large quantities, the hot upsetting bihexagonal head portion efficiency using routine is low, to meet visitor
Family demand, plan use cold-heading bihexagonal head portion form, are cut off because cold-heading need to use one, upsetting at the beginning of two, three smart upsettings, if
Using former unprocessed push rod, because not having anti-rotation boss, push rod is without anti-rotation face, after upsetting at the beginning of two is complete, using feed clamp clamp
Firmly during blank, blank always has fine rotation, and 12 jiaos of sides of blank can not align with smart 12 jiaos of sides of upsetting formpiston after causing just upsetting,
Cause there is folding to produce on the ring flange of transition, do not meet quality requirement.For this phenomenon, designed in two formers a kind of
Special push rod, prevent transfer process blank from rotating.Shown in Fig. 1 is a kind of cold-heading anti-rotation push rod schematic diagram used now, top
Bar cylinder, it is by 1 --- push rod anti-rotation face 2 --- bolt positioning table 3 --- push rod positioning table 4 --- push rod diameter, and it is raw
During production, the special push rod of design is put into just upsetting former, push rod anti-rotation has lock silk hole site in face of Zhunyin mould, tightens lock
Silk screw, screw are had gap with plane, can freely be slided and be defined in former by push rod, is reloaded into die cavity.
The content of the invention
The present invention is directed to problem above, there is provided a kind of new anti-rotation push rod, during for 12 corner bolt of cold-heading, and part station
Transfer process prevents blank from rotating.
Described in the present invention is new is the push rod that the rotation of station transfer process blank is prevented in a kind of part process.
It is made up of 1, push rod anti-rotation face 2, bolt positioning table 3, push rod positioning table 4, push rod diameter etc..The push rod is using materials such as T8A
The bar of material, the diameter to match with former endoporus is processed into as requested, being processed into width close to part to be processed one end can determine
The boss of position, for bar portion while milling out the plane for requiring length, former bores top wire hole, withstands plane by jackscrew, but push rod can also footpath
To movement, prevent push rod from rotating.
By the special push rod of design in the former of first upsetting position, after first upsetting blank shaping, discharging device ejection part, lathe
Caliper body clamps part blank, and because of Novel mandril projection, straight line groove card is formed with part bar portion end face in first upsetting
Together, fine rotation will not occur when lathe caliper body clamps part, blank is moved in smart upsetting former, is not in smart upsetting
12 jiaos of formpiston die cavity and the angular displacement problem of blank 12, so as to which Fold occur.Both increase die life, product quality
Also comply with requirement.
Brief description of the drawings：
Fig. 1 is former clamp structure schematic diagram；
Fig. 2 is a kind of push rod structure schematic diagram of part anti-rotation of processing of the present invention；
Embodiment：
Referring to Fig. 2,12 corner bolt of the present invention, it is machined by three station cold-headings, and Shi Erjiao is molded over sun
In model cavity, former is that bar portion positions and determined part length, the special push rod of design is installed in just in the former of upsetting position, first upsetting
After blank shaping, discharging device ejection part, lathe caliper body clamps part blank, because of Novel mandril projection, in first upsetting
When with part bar portion end face formed straight line groove be stuck, fine rotation will not occur when lathe caliper body clamps part,
Blank is moved in smart upsetting former, is not in 12 jiaos of smart upsetting formpiston die cavity and the angular displacement problem of blank 12.Both mould is made
Life-span increases, and product quality also complies with requirement.
Claims (2)
