Spherical support, support ring and swing arm one end are contacted by spherical support, and swing arm other end connects tup mold, and centre passes through pin shaft
Hinged with fuselage, connecting spring cylinder above swing arm realizes that pressure resets.
The beneficial effects of the utility model are:
(1) period of taking the lead is short.The frequency that forges of the heading machine can achieve 560 times/min.According to steel pipe sizes and head
Length requirement can be completed to take the lead in 10~30s, high production efficiency.
(2) pulsation load reduces frictional resistance during flow of metal, and deformation velocity is small, and deformation is uniform；Three dimension stress,
Be conducive to improve plastic deformation, avoid materials in the tube cracked during taking the lead, improve materials in the tube head strength and drawing property.

Specific embodiment
The utility model will be further described below with reference to the accompanying drawings.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, the utility model is a kind of cold drawing steel tube heading machine, including fuselage 9, feature
Be: 9 bottom of fuselage is equipped with motor 8, and 9 top of fuselage is equipped with main shaft 6, passes through transmission belt between motor 8 and main shaft 6
Connection, motor 8 drive main shaft 6 to rotate by transmission belt, and eccentric bushing 7 is housed on main shaft 6,4 support rings 5 are housed on eccentric bushing 7,
It is equipped with a spherical support 4, support ring 5 and 2 one end of swing arm in each support ring 5 to contact by spherical support 4, swing arm 2 is another
One end connects 1 mold 11 of tup, and centre is hinged by pin shaft 3 and fuselage 9,2 top connecting spring cylinder 10 of swing arm, realizes that pressure is multiple
Position.
The course of work of the utility model is as follows:
Heading machine is driven by a heavy-duty motor 8, and motor 8 drives main shaft 6 to rotate by transmission belt, is filled on main shaft 6
There is eccentric bushing 7,4 support rings 5 are housed on eccentric bushing 7, are equipped with a spherical support 4,5 He of support ring in each support ring 5
2 one end of swing arm is contacted by spherical support 4, and 2 other end of swing arm connects 1 mold 11 of tup, and centre is cut with scissors by pin shaft 3 and fuselage 9
It connects, 2 top connecting spring cylinder 10 of swing arm, realizes that pressure resets.When eccentric bushing 7 rotates, spherical support 4 does sinusoidal line and promotes fortune
Dynamic, then driven mold 11 is swung under the collective effect of spherical support 4 and spring cylinder 10 for swing arm 2.4 molds 11 are symmetrically distributed in
Around steel pipe 12, when 6 high speed rotation of main shaft, corresponding 4 tups 1 do opening closing movement, carry out high frequency to 12 head of steel pipe
It forges.
4 tups 1 are forged along the same section radial direction high frequency of material, and the metal of deformed area is made to be in three-dimensional compressive stress state,
And then radial compression and axially extending is generated, be conducive to the plasticity for improving 12 head of steel pipe.The deflection that high frequency forges simultaneously is small,
Deformation velocity is low, this feature makes the path of metal flow when blank deformation shorten, and frictional resistance is small, is easily deformed, greatly
Reduce the work of deformation of required deformation force and consumption.The shape of final undergauge is controlled by 1 mold 11 of tup.
Axial feed velocity directly affects the radial drafts of steel pipe 12.If axial feed velocity is too small, production efficiency
It is low；If speed is excessive, and easily causes deformation uneven, surface quality is bad.Take axial feed fast when forging under Warm status
Degree is 2~3m/min, takes 0.06~0.20m/min when forging under cold state.If improving axial feed velocity, need accordingly
Improve 12 revolving speed of steel pipe.
When radial forging, blank is rotated with collet, and 12 revolving speed of steel pipe is collet revolving speed, and the every strike of tup 1 is primary, steel
Pipe 12 turns over an angle, can control steel pipe 12 and does periodic wobble, it also can control to do Periodic Rotating, can protect in this way
The materials in the tube of card 11 gap portion of mold are also available to be forged.Collet revolving speed is higher, and 12 outer surface of steel pipe is more smooth, but collet turns
Speed is excessively high, may twist and warp blank during forging.Test proves: generally controlling collet revolving speed at 30 turns per minute, i.e.,
It can guarantee that 12 surface of steel pipe is smooth and will not twist and warp pipe.
