Specific embodiment
In order to which technical problems, technical solutions and advantages to be solved are more clearly understood, tie below
Accompanying drawings and embodiments are closed, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only
To explain the present invention, it is not intended to limit the present invention.
Also referring to Fig. 1 to Fig. 3, now derailing valve pull ring cold drawing apparatus for correcting provided by the invention is illustrated.Institute
State derailing valve pull ring cold drawing apparatus for correcting, including rack, driving mechanism, correction mould 1, pull rod 2 and bindiny mechanism 3；
Correction mould 1 is installed in the rack, and the guidance cavity 11 and correction chamber 12 of connection are equipped in correction mould, corrects chamber 12
Shape it is identical as the shape of derailing valve pull ring 4, correction chamber 12 includes side lever chamber for accommodating the side lever 41 of derailing valve pull ring
121；Guidance cavity 11 is for leading into the side lever 41 of derailing valve pull ring 4 in side lever chamber 121；
The first end of pull rod 2 is connect with the power output end of the driving mechanism, and second end and the end of side lever 41 are removable
That unloads is fixedly connected, and pull rod 2 passes through from the cavity on correction mould 1 and for pulling derailing valve pull ring 4 in correction chamber 12；
Bindiny mechanism 3 is equipped with and is linked together for the second end of connecting rod 2 and the end of side lever 41, bindiny mechanism 3
Universal joint 31 and clamping joint 32, clamping joint 32 are dismountable by the pin hole 42 and derailing valve pull ring 4 for being located at 41 end of side lever
It is fixedly connected；Clamping joint 32 is equipped with the torsion block 321 of protrusion 41 external cylindrical surface of side lever, and guidance cavity 11 and the bottom surface for correcting chamber 12 are set
There is gradually smaller torsion slot 13, pin hole 42 is remedied to correct position to the extruding of torsion block 321 by the side wall of torsion slot 13
It sets.
Derailing valve pull ring cold drawing apparatus for correcting provided by the invention, compared with prior art, beneficial effect is: passing through company
After derailing valve pull ring 4 is connected to the second end of pull rod 2 by connection mechanism 3, pull rod 2 under the action of the driving mechanism can be by derailing valve
Pull ring 4 pulls in the correction chamber 12 of correction mould 1, and derailing valve pull ring 4 is remedied to correct shape under the extruding of cavity wall, pulls in
In the process, guidance cavity 11 can constrain bindiny mechanism 3, and derailing valve pull ring 4 is made to progress into correction chamber under the traction of bindiny mechanism
In 12；Meanwhile in the pull-in procedure, if the malposition of pin hole 42, the meeting under the constraint of torsion 13 side wall of slot of torsion block 321
Driving force is generated to side lever 41, side lever 41 can twist under the constraint of clamping joint 32 and the driving of torsion block 321, make pin
Hole 42 is torqued into correct position；Derailing valve pull ring cold drawing apparatus for correcting provided by the invention in the prior art by artificial or add
The mode that the mode of heat corrects derailing valve pull ring 4, not only mechanization degree is high, but also correcting process is simple and efficient,
While correcting shape, pin hole 42 is rotated to correct position, and the derailing valve pull ring 4 after guaranteeing correction being capable of normal use.
The application method of derailing valve pull ring cold drawing apparatus for correcting provided by the invention are as follows:
(1) universal joint 31 is threadedly attached in the second end of pull rod 2, by pull rod 2 and universal joint 31 from correction
The tail end of mould 1 penetrates, and is pierced by from the guidance cavity 11 for being located at head end, as shown in Figure 1 and Figure 5；Clamping joint 32 is passed through into screw thread and ten thousand
It is connected to the other end of connector 31；In the course of work, universal joint 31 and clamping joint 32 can not be removed from side lever 41；To derailing
Valve pull ring 4 is screened, and deformation is biggish to scrap, and deformation is smaller, recoverable to be ready for cold drawing correction；
(2) derailing valve pull ring 4 is fixedly attached to the other end of clamping joint 32 by pin hole 42；31 freedom degree of universal joint
It is higher, clamping joint 32 is connect from different location and different directions with 41 end of side lever, derailing valve is enabled adaptation to
The deformation of pull ring 4；
(3) start driving mechanism, derailing valve pull ring 4 is slowly pulled in correction mould 1, as shown in Figure 6；In the process,
Universal joint 31 is initially entered under the traction of pull rod 2 in correction chamber 12, while universal joint 31 and clamping joint 32 are in guidance
Under the constraint of 11 cavity wall of chamber, in 32 approaching side rod cavity 121 of clamping joint after, the clamping joint 32 on both sides is in parastate, is connected to
The side lever 41 of 32 other end of clamping joint is also remedied to parastate by clamping joint 32 by force；Envelope universal joint 31 and clamping joint 32
External cylindrical surface it is identical as the external cylindrical surface shape of side lever 41, the shape adaptation with side lever chamber 121.Herein it should be noted that
Clamping joint 32 must have certain length, with guarantee torsion block 321 before entering and reversing slot 13, the approaching side rod cavity of clamping joint 32
121 certain lengths, clamping joint 32 only have oneself reversed along its length with own axes under the constraint of 121 side wall of side lever chamber
By spending；Block 321 is reversed into after reversing slot 13, if 42 position of pin hole is correct, reverses the meeting of block 321 and the torsion at side lever chamber 121
Turn trough 13 will not be squeezed just with the side wall of torsion slot 13；If the malposition of pin hole 42, reverse block 321 into
Enter to correct chamber 12 will receive the extruding of torsion 13 side wall of slot in the process, so that side lever 41 is twisted, pin hole 42 will be with side lever 41 1
It is same to be torqued into correct position；In general, torsion block 321 be arranged in pin hole 42 to positive position, also can be set with pin
The position that hole 42 is turn 90 degrees partially guarantees that torsion block 321 is corresponding with torsion 13 position of slot.
(4) final derailing valve pull ring 4 will be pulled completely into correction chamber 12, as shown in Figure 7；It corrects chamber 12 and derailing valve is drawn
The shape of ring 4 is identical, is all U-shaped structure；Derailing valve pull ring 4 is in correction chamber 12 by driving mechanism pressure maintaining shape after a certain period of time
It can restore；
(5) driving mechanism is driven in the reverse direction pull rod 2, by derailing valve pull ring 4 from correction mould 1 in release, by derailing valve pull ring 4 from
It is removed on clamping joint 32, completes the cold drawing correction of derailing valve pull ring 4.Herein it should be noted that 4 reverse push of derailing valve pull ring
During out, the initial stage must guarantee that universal joint 31 is located in side lever chamber 121, will be drawn with constraining universal joint 31 by it
Thrust on bar 2 is transmitted on clamping joint 32；Therefore, the length of side lever chamber 121 is greater than the length of side lever 41, in the length exceeded
It can be not provided with torsion slot 13.
It is illustrated in figure 4 the structure composition of derailing valve pull ring 4.
As a kind of specific embodiment of derailing valve pull ring cold drawing apparatus for correcting provided by the invention, referring to Fig. 8, card
Connector 32 further includes casing 322, sliding core pole 323 and short column 324；
