Description
Technical field
The utility model relates to a kind of cross wedge rolling mill roller, particularly a kind of cross wedge rolling mill roller backgauge guide plate slack adjuster.
Background technology
Cross wedge rolling is a kind of multidiameter class part forming new technology; Its basic principle is: the bar after will heating is sent into two homodromal having in the middle of the protruding mould of wedge shape; Bar is under the effect of wedge shape mould; Do and the reverse gyration of mould, bar generation radial compression is out of shape and is extended axially distortion simultaneously, thus shaping ladder axial workpiece.This technology is mainly used in the big axial workpiece of production lot; Comprise: axial workpieces such as automobile, one, two of gear box of tractor, jackshaft, back axle bevel gear shaft, engine cam, all kinds of motor shafts; Cross wedge rolling technique technology has efficiently, low consumption, characteristics such as energy-conservation, is the advanced technology of producing axial workpiece.
The effect of backgauge guide plate is the process unit that keeps rolled piece stable rotation in the space that limits in the cross wedge rolling, is the important device that guarantees that cross wedge rolling forming technology normal and stable is carried out.The backgauge guide plate of cross wedge rolling is a whole plate of fixing at present, and the gap of backgauge guide plate is fixed, and can not change.
The present situation of present cross wedge rolling backgauge guide plate: in the operation of rolling of ladder longaxones parts; Send in the middle of mould and the backgauge guide plate after the bar heating; Lean on the backgauge guide plate with original maximum gauge place and begin to rotate, along with the distortion of bar generation radial compression with extend axially distortion, bar part stepped diameters diminishes; But backgauge guide plate gap is constant; The step that the bar diameter diminishes just leans on less than the backgauge guide plate, for the ladder longaxones parts, this moment diameter diminish, the part of axial elongation can occur bending and deformation.
Solving at present the diastrophic main method of ladder longaxones parts is with straightener hot alignment of manual work and hydraulic press straighten while cold, but these two kinds of methods not only labour intensity is big, and efficient is very low.
The utility model content
The utility model has mainly overcome the deficiency of prior art, and a kind of backgauge guide plate slack adjuster is provided, and the part that diameter diminishes when solving rolling ladder longaxones parts does not reach the backgauge guide plate and the problem that occurs bending and deformation.
The technical scheme of the utility model is achieved in that
Cross wedge rolling mill roller backgauge guide plate slack adjuster comprises the backgauge guide plate seat, and the backgauge guide plate is installed on the backgauge guide plate seat; On the backgauge guide plate, be provided with the linkage that clamps bar in order to compensation, described linkage comprises at least two flexible guide plates, guide plate push arm; Passive connecting rod, kinematic link and drive connecting rod, flexible guide plate is arranged in the guide groove of backgauge guide plate front end; The quantity of guide plate push arm, passive connecting rod is identical with the quantity of flexible guide plate, and an end and the backgauge guide plate of passive connecting rod are hinged, and the other end of passive connecting rod is hinged with an end, the kinematic link of guide plate push arm respectively; The other end of guide plate push arm and flexible guide plate are hinged; One end of kinematic link and an end of drive connecting rod are hinged, and the other end of drive connecting rod and backgauge guide plate are hinged, and this hinged end of drive connecting rod and backgauge guide plate also is connected with the drive connecting rod push arm; Drive connecting rod and drive connecting rod push arm are for being rigidly connected, and the drive connecting rod push arm links to each other with the power set that promote himself to rotate.
As preferably, described power set are cylinder, and the piston rod of cylinder and drive connecting rod push arm are hinged.
As preferably, the backgauge guide plate is installed on the backgauge guide plate seat through bolt.
The principle and the beneficial effect of the utility model are:
When major axis class rolled piece, bar radial compression distortion takes place in the operation of rolling, when diameter diminishes, cylinder is released fast, drives drive connecting rod push arm and drive connecting rod and clockwise rotates; Drive connecting rod effect kinematic link makes kinematic link make rectilinear motion to the right simultaneously, and kinematic link acts on passive connecting rod and guide plate push arm simultaneously; Make passive connecting rod do and clockwise rotate that the guide plate push arm is released forward, thereby make flexible guide plate release forward simultaneously; This moment, the major axis class rolled piece stepped diameters part that diminishes leaned on flexible guide plate respectively; Guaranteeing that rolled piece has three points to lean on guide plate simultaneously, thereby avoid rolled piece to occur bending and deformation, wait rolled piece accomplish smoothly the operation of rolling and with mould separating after; Roll rotates to initial position and stops the rotation; The instantaneous withdrawal of cylinder simultaneously, package unit returns to original state, this device single end of run.

The specific embodiment
The specific embodiment of the utility model is following:
Embodiment: a kind of cross wedge rolling mill roller backgauge guide plate slack adjuster, as shown in Figure 1, comprise backgauge guide plate seat 7; On backgauge guide plate seat 7, through bolt backgauge guide plate 9 is installed, on backgauge guide plate 9, is provided with the linkage that clamps bar in order to compensation, described linkage comprises two flexible guide plates 1; Two guide plate push arms 2; 6, one kinematic links 8 of two passive connecting rods and a drive connecting rod 3, flexible guide plate 1 is arranged in the guide groove of backgauge guide plate 9 front ends; One end and the backgauge guide plate 9 of passive connecting rod 6 are hinged; The other end of passive connecting rod 6 is hinged with an end and the kinematic link 8 of guide plate push arm 2 respectively, and the other end of guide plate push arm 2 and flexible guide plate 1 are hinged, and an end of kinematic link 8 and an end of drive connecting rod 3 are hinged; The other end of drive connecting rod 3 and backgauge guide plate 9 are hinged; Drive connecting rod 3 also is connected with drive connecting rod push arm 4 with backgauge guide plate 9 these hinged ends, and drive connecting rod 3 and drive connecting rod push arm 4 are for being rigidly connected, and drive connecting rod push arm 4 and the power set 5 that promote himself to rotate link to each other; Described power set 5 are cylinder, and the piston rod of cylinder and drive connecting rod push arm 4 are hinged.
Like Fig. 2, shown in Figure 3, when normal the use, respectively be provided with a cover backgauge guide plate in the bar both sides, bar 10 is sent in the middle of mould and the backgauge guide plate; Equipment begins to start then, and bar 10 begins to take place radial and axial distortion along with the mould rotation; When bar generation radial deformation, when diameter diminished, cylinder was released fast; Driving drive connecting rod push arm 4 is that the axle center clockwise rotates with drive connecting rod 3 with a C, and drive connecting rod 3 effect kinematic links 8 simultaneously make kinematic link 8 works rectilinear motion to the right; Kinematic link 8 acts on passive connecting rod 6 and guide plate push arm 2 simultaneously, makes that passive connecting rod 6 is that the axle center is done and clockwise rotated with a D, and guide plate push arm 2 is released forward; Thereby make flexible guide plate 1 release forward simultaneously, this moment, bar point E leaned on flexible guide plate 1 respectively with some G step, had the some F of three some point E, some G and bar diameter maximum to lean on the pusher guide plate simultaneously to guarantee bar; Thereby avoid bar to occur bending and deformation, wait bar accomplish smoothly the operation of rolling and with mould separating after, roll rotates to initial position and stops the rotation; The instantaneous withdrawal of cylinder simultaneously, package unit returns to original state shown in Figure 1, this device single end of run.
