Abstract
The invention relates to the technical field of a finish forging machine and discloses a height-adjustable workpiece support of a finish forging machine. Height of the workpiece support is adjusted by a programmable logic controller (PLC). The height-adjustable workpiece support of the finish forging machine is characterized by at least comprising a supporting wheel, the workpiece support, a fan-shaped gear, a gear, an encoder, a hydraulic cylinder, a servo valve and the PLC; the workpiece support is formed by two fixedly connected arms, an included angle between the two arms is constant; the supporting wheel is fixedly arranged at an end part of one arm, the end part of the other arm is fixedly connected with a lever end of the hydraulic cylinder; the servo valve is arranged at an oil inlet end of the hydraulic cylinder; the workpiece support is further fixed with the fan-shaped gear in a linkage way, the fan-shaped gear is meshed with the gear; the encoder is arranged on a rotating shaft of the gear and is communicated with the servo valve and the PLC. By adopting the workpiece support, the height of the workpiece support of the finish forging machine is adjustable; so that deformation of a forging material can be avoided when the finish forging machine is used for forging.
Description
Technical field
It is adjustable height precise forging machine workpiece support the present invention relates to precise forging machine technical field.
Background technology
Precise forging machine when elongated material is forged, in order to prevent heating after forging material because the effect of gravity occurs bending and deformation,
Influence forges quality, all forging material can be being supported at swaging with the work mounting s for playing aiding support, to reduce or disappear
Except the flexural deformation of forging material.But, the supporting arm of current work mounting s under the driving of hydraulic cylinder, the lifting heights of supporting arm
It is non-adjustable, meanwhile, cylinder pressure is unable to stepless voltage regulation, so, when elongated material is forged, cylinder pressure is passed by supporting arm
It is delivered on elongated material, elongated material is generated flexural deformation, has a strong impact on product quality.This patent sets supporting arm lifting heights
It is calculated as adjustable, preferably resolves this technical barrier.
The content of the invention
It is an object of the invention to provide a kind of adjustable height precise forging machine workpiece support, precise forging machine workpiece support is realized
Height adjustable, makes precise forging machine when forging, it is to avoid deformation is expected in forging.
The technical scheme is that adjustable height precise forging machine workpiece support, it is realized to workpiece by PLC
The height regulation of supporting, it is characterized in that：It at least include support roller, work mounting s, sector gear, gear, encoder, hydraulic cylinder,
Servo valve and PLC；Workpiece support is made up of two arms being fixedly connected, and angle between two arms is constant, one
The end of arm is fixedly installed support roller, and the end of another arm is fixedly connected the lever end of hydraulic cylinder, and the oil inlet end of hydraulic cylinder sets
It is equipped with servo valve；Workpiece support is also linked with sector gear and fixes, and sector gear is engaged with gear, is provided with the rotating shaft of gear
Encoder；Encoder is turned on servo valve with PLC.
Described work mounting s include two arms, and one arm is straight-arm, and its front end is fixedly connected with the lever end of hydraulic cylinder；
Another arm is L-shaped, and its front end is fixed with support roller, is linked with sector gear at flex point and fixed.
Described support roller support forging material.
Described PLC inside editor has the functional relation of support roller height and gear corner.
Described encoder is photoelectric encoder.
It is characteristic of the invention that employing the closed-loop control of PLC, the corner of work mounting s is measured by encoder,
To obtain control signal, the stroke of hydraulic cylinder is controlled by controlling servo valve, so as to obtain adjustable work mounting s highly；Together
When work mounting s lifting heights can be adjusted according to the diameter of forging material, it is to avoid conventional workpiece branch honours the bending of forging material
Effect, improves product quality.

Specific embodiment
As shown in figure 1, adjustable height precise forging machine workpiece support is that the height to work mounting s 3 is realized by PLC 9
Regulation.
The structure of work mounting s 3 is, by two arms into fixed angle, to be fixed together.One arm is L-shaped, one arm
It is straight-arm.
The front end of L-arm is fixed with support roller 2, the support forging of support roller 2 material 1, that is, forge the height of material 1 by the bearing height of support roller 2
Determine.
Linked with sector gear 4 at the flex point of L-arm and fixed, be i.e. the rotation of L-arm can drive turning for sector gear 4
It is dynamic.
The front end of straight-arm is fixedly connected with the cylinder rod end of hydraulic cylinder 7, and hydraulic cylinder 7 can promote straight-arm to move, so as to drive
The mass motion of work mounting s 3.
The oil inlet end of hydraulic cylinder 7 is provided with servo valve 8, the cylinder rod motion of the control hydraulic cylinder 7 of servo valve 8.
Sector gear 4 engages linkage with gear 5, there is encoder 6 in the rotating shaft of gear 5, and encoder 6 uses photoelectric coding
Device, can read and transmit the corner of gear 5.
Encoder 6 and servo valve 8 are all turned on PLC 9, and PLC inside editor has the height of support roller 2 and gear
The functional relation of 5 corners, you can to calculate the height of support roller 2 according to the corner of gear 5.
The height of support roller 2 is by the brachium of work mounting s 3, sector gear 4 and gear 5 with the functional relation of the corner of gear 5
, than determining, the parameter according to each part is different, and functional relation is different for tooth.
During work, support roller 2 holds up forging material 1, and encoder 6 reads the corner of gear 5, and output is sent into PLC
9, PLC 9 draws height the need for support roller 2 by calculating, and by signal output to servo valve 8, servo valve 8 controls liquid
The oil inlet quantity of cylinder pressure 7, so as to promote lever motion, drives work mounting s 3 to move, so as to by support roller, 2 liters are lifted to the height for needing.
The part and structure that the present embodiment is not described in detail belong to the well-known components and common structure or conventional hand of the industry
Section, does not describe one by one here.
