Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing.
It is described further referring to figs. 1 to main roll off roller pushing meanss embodiment of the Fig. 3 to the utility model Ring Rolling Machine.
A kind of main roll off roller pushing meanss of Ring Rolling Machine including rack 1 and are fixed in rack 1 referring to Fig.1
Hydraulic cylinder 2, sliding is connected with the sliding block 91 that main roll off roller 9 is arranged in rack 1, is rotatably connected to main roll off roller 9, liquid on sliding block 91
3 one end of piston rod of cylinder pressure 2 is the connecting pin for driving main roll off roller 9 to slide, and connecting pin is connect with sliding block 91, works as work at this time
When stopper rod 3 upwardly or downwardly slides, piston rod 3 can drive main roll off roller 9 to slide up and down, and the other end of piston rod 3 is from liquid
The top of cylinder pressure 2 is stretched out to form extension end, and the extension end of piston rod 3 outwardly protrudes to form limited block 31, passes through the work of hydraulic cylinder 2
The stretching of stopper rod 3 or income can push main roll off roller 9 to slide in rack 1, carry out spreading to forging, hydraulic cylinder 2 it is outer
Shell is equipped with bulge loop 21, and in the present embodiment, bulge loop 21 is arranged on the top surface of hydraulic cylinder 2, and bulge loop 21 is set on piston rod 3,
I.e. bulge loop 21 and piston rod 3 are coaxially disposed, and the contact area of such stop collar 5 and limited block 31 is bigger, can make stop collar 5
Be more uniformly stressed, improve the stability of pushing meanss, be threaded on the outer circumference surface of bulge loop 21 for adjust limit
The stop collar 5 of distance, stop collar 5 are threadedly coupled with bulge loop 21 between position block 31 and oil cylinder, and rack 1 is equipped with driving stop collar 5
The driving part of rotation, in the present embodiment, driving part includes the driving pulley 4 being rotatably arranged in rack 1, driving pulley 4
Belt 8 is connected between stop collar 5,5 outer circumference surface of stop collar is equipped with the concave ring for placing belt 8, at this time stop collar 5
V belt translation can be realized between driving pulley 4 by rotation driving pulley 4, stop collar 5 can be driven and rise or decline.
Referring to Fig. 2, since hydraulic cylinder 2 is higher with respect to ground location, manual operation driving pulley 4 rotate it is inconvenient,
Therefore, shaft 6 is equipped in rack 1, one end far from ground is fixedly connected with driving pulley 4, and one end close to ground is equipped with
For the operation portion of rotating shaft 6, in the present embodiment, operation portion includes the handwheel 61 for being fixed at 6 end of shaft, works as needs
When stop collar 5 being driven to rotate, rotate handwheel 61, the rotation of driving pulley 4 can be realized, due to driving pulley 4 and stop collar 5 it
Between connected by belt 8, by V belt translation, the rotation of stop collar 5 can be driven.
Referring to Fig. 2 and Fig. 3, in order to keep the rotation process of shaft 6 relatively reliable, it is equipped with placement seat 7 in rack 1, turns
Axis 6 and placement seat 7 are rotatablely connected, and are equivalent to and are mounted with axle sleeve in shaft 6, can prevent shaft 6 from occurring during rotation
It shakes, since stop collar 5 is gone up and down, during stop collar 5 is gone up and down, is easy to cause driving pulley 4 and stop collar 5
In one plane, do not influence transmission accuracy, therefore, in shaft 6 be equipped with external screw thread 62, on placement seat 7 be equipped with it is outer
The internal screw thread 71 that screw thread 62 cooperates is cooperated by external screw thread 62 and internal screw thread 71, the screw thread of shaft 6 Yu placement seat 7 can be realized
It connects, the screw pitch of external screw thread 62 is equal with the screw pitch of internal screw thread 71 of bulge loop 21 with stop collar 5 in shaft 6, at this time driving pulley 4
It is equal with the diameter of stop collar 5, in this way after rotating shaft 6, since driving pulley 4 is equal with the rotation amplitude of stop collar 5,
And the parameter of the screw thread on stop collar 5 is equal with the parameter of screw thread in shaft 6, and driving pulley 4 and limit may be implemented in this way
Ring 5 can improve the transmission accuracy of device with synchronization lifting.
Working principle is summarized: stop collar 5 being threaded on convex block, rotary spacing ring 5, is passed through screw-driven, limit
Ring 5 can be raised or fall in bulge loop 21, since limited block 31 is abutted with stop collar 5, and then adjustable limit
The position of cylinder body of the block 31 apart from hydraulic cylinder 2, and then the stroke of piston rod 3 can be adjusted, in use, by adjusting limit
Ring 5 height in position can carry out adjusting appropriate, and then the overhang of adjustable piston rod 3 to the stroke of piston rod 3, work as master
When can not be processed between roll milling wheel and forging there are certain gap, the height of stop collar 5 is reduced a bit, at this time limited block 31
Can slide downward, piston rod 3 can continue to stretch out a part, when main roll milling wheel overhang is excessive, cause forging stress excessive
When, stop collar 5 is rotated backward, 5 upward sliding of stop collar, piston rod 3 is jacked up a bit upwards, and then can be by main roll milling wheel
It withdraws a bit.
Above are merely preferred embodiments of the utility model, the protection scope of the utility model is not limited merely to above-mentioned
Embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should be pointed out that pair
For those skilled in the art, several improvements and modifications without departing from the principle of the utility model,
These improvements and modifications also should be regarded as the protection scope of the utility model.
