Abstract
The utility model discloses a three-roller synchronous adjusting device for a Y type rolling mill, which is used for the metallic wire rod rolling of cold drawing rolling in a passive type. The utility model is mainly composed of a machine frame, a backup block, a roll, an adjusting nut, an adjusting rod, a sliding block, etc. The three-roller synchronous adjusting device for a Y type rolling mill can realize the synchronization adjustment in relatively great range of three rolls. The utility model has the advantages of long service life, high adjusting accuracy, high production efficiency, etc.
Description
The utility model relates to a kind of three-high mill of rolled metal wire rod, arranging synchronously of a kind of three-roller Y shaped rolling mill roll specifically, and it is specially adapted to passive type (no driving force itself) cold drawing and rolling metal wire rod.
At present, domestic three-roller Y shaped milling train is how similar with gondola similar rolling mill structure with West Germany, and the adjusting device of its roll generally can be divided into two kinds: a kind of is to realize three rolls structural shape of rotation synchronously with bevel gear.Because it is subjected to the restriction of bevel gear backlash, the adjusting range of roll is very little, can only accomplish trickle pass correction.Another kind is no synchronous bevel gear, and three rolls can be adjusted separately.The guiding mechanism of this pattern is not owing to be subjected to the restriction of backlash, and the mill opening adjusting range is bigger, but because each roll can only be adjusted separately, operate very loaded down with trivial detailsly, and adjustment precision and production efficiency are also low, are difficult to satisfy the needs of cold rolling wire production.
The purpose of this utility model is in order to overcome the deficiency of existing technology, a kind of y-type rolling mill three roller synchronizing controls with larger opening to be provided, and it can satisfy passive type cold drawing and rolling wire rod is exempted from the pointing operation to rolling accuracy and threading needs fully.
The purpose of this utility model realizes by following concrete device: a kind of y-type rolling mill three roller synchronizing controls, form by frame, rest pad, roll, adjustment nut, adjusting lever, slide block, pendulum point bearing pin, slideway, fulcrum pin axle, regulate and adjust nut, just can realize the synchronous adjustment of three rolls.
Y-type rolling mill three roller synchronizing controls of the present utility model are because three rolls can be implemented in interior in a big way adjustment synchronously, and the advantage of being brought is as follows:
(1) since the adjustment of three rollers carry out synchronously, so milling train is adjusted efficient and precision is all very high, make rolling operation become simply, quick, effective.
(2) in the operation of threading that passive type cold drawing and rolling wire rod begins, can remove pointing equipment and pointing operation from, directly (three rolls are open at this moment) with original wire rod in passage is sent into milling train, thereby improved production efficiency greatly.
(3) in order to reduce the stress of pendulum point sliding system, adopt the form of slide block, thereby increased contact-making surface, reduced wearing and tearing, improved the precision and the service life of whole rolling.
(4) because its adjusting range is bigger, can realize the recycling of roll, promptly within the specific limits, as long as three dimension of roller are identical, its diameter is unrestricted, has so just reduced the roller consumption, greatly reduces production cost.
Fig. 1 is the main cutaway view of y-type rolling mill three roller synchronizing controls.
Fig. 2 is the side view of y-type rolling mill three roller synchronizing controls.
Describe most preferred embodiment of the present utility model in detail below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, y-type rolling mill three roller synchronizing controls comprise: frame 8, roll 6, rest pad 5 is adjusted nut 1, adjusting lever 2, be arranged in the passage 9 of adjusting lever, be positioned at the slideway 10 on the adjusting lever 2, be installed in the square slider 3 in the slideway 10, the pendulum point bearing pin 4 in the square slider 3 and be installed in fulcrum pin axle 7 on the frame 8.
When three rolls of needs open, nut 1 is adjusted in rotation in the counterclockwise direction, adjusting lever 2 is promptly to right translation, slide block 3 drives rest pad 5 by bearing pin 4 and does counter-clockwise swing around fulcrum pin axle 7, this moment slide block 3 except with adjusting lever 2 to right translation, also will slide at vertical direction, the action that is installed in three rolls 6 on the adjusting lever 2 is identical, thereby has finished opening synchronously of three rolls.When three rolls of needs shrink (as reaching normal as-rolled condition from the threading state), be rotated in a clockwise direction and adjust nut 1, adjusting lever 2 is to left, and slide block 3 drives rest pad 5 by bearing pin 4 and does clockwise swing around fulcrum pin axle 7, thereby makes three rolls 6 with shrinking.Apply roll-force then, reach normal as-rolled condition.
Claims (5)
1, a kind of y-type rolling mill three roller synchronizing controls comprise, frame, and roll, rest pad is characterized in that: roll adjusting device also comprises the adjustment nut, adjusting lever, slide block, pendulum point bearing pin, slideway and fulcrum pin axle.
2, according to the y-type rolling mill three roller synchronizing controls of claim 1, it is characterized in that: described pendulum point bearing pin is installed in the slide block, and described slide block is installed in the slideway on the adjusting lever.
3, according to the y-type rolling mill three roller synchronizing controls of claim 1, it is characterized in that: the passage that passes wire rod is arranged in the described adjusting lever.
4, according to the y-type rolling mill three roller synchronizing controls of claim 1, it is characterized in that: described fulcrum pin axle is installed on the frame.
5, according to the y-type rolling mill three roller synchronizing controls of claim 1 or 2, it is characterized in that: described slide block is square.
