Abstract
An axial stop block for the lower working roll of a shell section forming machine is disclosed, applied to a forming technique for a heavy metal ring piece. The lower working roll of a shell section forming machine has an axial play and a vertical high-frequency swinging during a working process; the traditional operation side bearing seat structure of the lower working roll can prevent the axial play of the lower working roll only, and cannot compensate the vertical high-frequency swinging. The axial stop block for the lower working roll disclosed by the utility model is installed on the operation side bearing seat of the lower working roll and produced to be a rotary stop block disposed on a support shaft, which can prevent the axial play of the lower working roll and compensate the vertical high-frequency swinging of the lower working roll while working, so that the forming process need is satisfied and the smooth progress of forming is ensured well.
Description
Technical field
The utility model relates to a kind of heavy duty metal ring rolling equipment, relates in particular to a kind of structure of shell ring forming machine.
Background technology
The shell ring forming machine is the heavy duty metal ring rolling equipment of my company's independent research, is used for existing heavy duty metal ring manufacturing process in the subrogate country.It can greatly improve the production efficiency of ferrule piece, shortens the production cycle, saves material, reduces cost, and improves the quality of products and performance.
When the rolling mill practice of shell ring forming machine has determined bottom working roll work, produce the violent swing that upper and lower makes progress, and the bottom working roll bearing block structure of conventional panels milling train can't satisfy the rolling mill practice requirement of shell ring forming machine, therefore special-purpose bottom working roll axial stop on a kind of shell ring forming machine of necessary utility model.
The utility model content
Technical problem to be solved in the utility model is: design and produce a kind of device, prevent the violent swing that bottom working roll axial float and upper and lower make progress effectively in the production process of shell ring forming machine.For solving the problems of the technologies described above, the utility model proposes following technical scheme: a kind of shell ring forming machine bottom working roll axial stop, it possesses following characteristics: the centre at a rectangle housing is provided with through hole, is the gap that is slidingly matched between this through hole and the described shell ring forming machine bottom working roll fore side bearing block side back shaft.Can also between through hole and back shaft, add copper sheathing, also be the gap that is slidingly matched between copper sheathing and the back shaft.The top of described rectangle housing also is provided with lubrication hole.
Adopt a kind of shell ring forming machine bottom working roll axial stop of above technical scheme, not only can prevent the bottom working roll axial float, also compensating action has been played in the swing of bottom working roll.Can well satisfy the rolling mill practice requirement of shell ring forming machine, reduce maintenance cost simultaneously, also prolong the service life of equipment.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in further details.
Fig. 1 is a shell ring forming machine bottom working roll structural representation.
Fig. 2 is the A-A section of Fig. 1.
Fig. 3 is the axonometric drawing of the utility model shell ring forming machine bottom working roll axial stop.
The specific embodiment
Among Fig. 1, the connotation of sequence number is as follows: 1. fore side bearing block; 2. link stopper; 3. back shaft; 4. lubrication hole; 5. through hole; 9. bottom working roll; 10. transmission side bearing block.In Fig. 3, the utility model shell ring forming machine bottom working roll axial stop 2 is made rectangular structure, and lubrication hole 4 is arranged above, and lubricating oil can enter thus, lubricate.There is a through hole 8 centre.As can be seen, block through hole 8 matches with back shaft 3 by copper sheathing in Fig. 1 and 2, realizes revolution.There are 3 on the back shaft 3 and along the circumferential direction go up uniform screwed hole 5, axle head baffle plate 7 is fixed on the back shaft 3, realize the axial limiting of block 2 with bolt 6.
When the shell ring forming machine was worked, the bottom working roll axle head plate washer that is fixed on the shell ring forming machine frame was locked with block 2, so just can prevent the bottom working roll axial float.When bottom working roll produced the violent swing that upper and lower makes progress, 3 relative revolutions of block 2 and back shaft had been played compensating action to the swing of bottom working roll.
In sum, this new shell ring forming machine bottom working roll axial stop can well satisfy the rolling mill practice requirement of shell ring forming machine, has guaranteed carrying out smoothly of Rolling Production technology, has reduced maintenance cost simultaneously, prolongs the service life of equipment.
Claims (2)
