Abstract
The invention discloses a roll changing mechanism for a working roll of a rolling mill. An upper bearing seat and a lower bearing seat are arranged on an installing seat of a work side and an installing seat of an operating side respectively. The shaft axis of the upper bearing seat and the shaft axis of the lower bearing seat are arranged in parallel. An upper working roll and a lower working roll penetrate through the upper bearing seat and the lower bearing seat respectively. An equal-height hinge pin is fixedly arranged on the upper surface of the lower bearing seat at the working side. A depth hole and a shallow hole are formed in the bottom face of the upper bearing seat at the working side. Another equal-height hinge pin is fixedly arranged on the upper surface of the lower bearing seat at the operating side. A depth hole and a shallow hole are formed in the bottom face of the upper bearing seat at the operating side. According to the structure of the roll changing mechanism for the working roll of the rolling mill, the equal-height hinge pin is included on the upper surface of the lower bearing seat, and two holes with different depths are formed in the bottom of the upper bearing seat correspondingly, the function of adding a height-equal block manually is realized, and fast, convenient and safe roll changing is realized.
Description
Technical field
The invention belongs to metallurgy rolling equipment technical field, the fast roll changing of four-high mill working roll can be met, relate to a kind of operation roll of mill roll change structure.
Background technology
In milling equipment, work roll changing is absolutely necessary process, can backheating at four rollers, in cold-rolling mill, because top working roll does not have track, can only be carried on the back out by bottom working roll when roll change, damage in order to avoid roll surface and reposefully top roll carried on the back out, on when roll change, bottom working roll roll surface must not contact, so before replacing working roll, what need at transmission side and fore side is upper, equal height cushion block is placed in the middle of step, so that bearing block can contact with each other, reposefully by upper, bottom working roll is together extracted out, due to the restriction of transmission side position, very inconvenient when placing isometry block, to waste time and energy and very dangerous.
Summary of the invention
The object of this invention is to provide a kind of operation roll of mill roll change structure, solve in prior art and manually need place equal height cushion block when changing working roll, changing working roll wastes time and energy, ineffective problem.
The technical solution adopted in the present invention is, a kind of operation roll of mill roll change structure, active side and fore side mount pad are respectively arranged with top chock and step, and top chock and step axis parallel are arranged; Top working roll and bottom working roll is installed with respectively in top chock and step,
Be fixedly installed a contour bearing pin at the step upper surface of active side, be provided with a deep hole and a shallow bore hole in the bottom surface of the top chock of active side; Equally, be fixedly installed another contour bearing pin at the step upper surface of fore side, be provided with a deep hole and a shallow bore hole in the bottom surface of the top chock of fore side.
Operation roll of mill roll change structure of the present invention, is further characterized in that:
When step and top chock near time, two described contour bearing pins can be socketed with two deep holes simultaneously or two contour bearing pins can while be socketed with two shallow bore holes.
The degree of depth of two deep holes is greater than the degree of depth of two shallow bore holes.
The invention has the beneficial effects as follows, carry contour bearing pin at step upper surface, the corresponding hole arranging two different depths bottom top chock, realizes the function manually increasing isometry block, achieves quick, convenient and safe roll change.This structure is simply novel, easy to implement, is convenient to roll change, safe and reliable, successful, manually need not increase isometry block, time saving and energy saving, has high promotional value.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
With reference to Fig. 1, Fig. 2, the structure of prior art (before improvement) is, active side and fore side mount pad are respectively arranged with top chock 1 and step 5, and top chock 1 and step 5 axial line be arranged in parallel up and down; Being installed with top working roll 2 and bottom working roll 4 respectively in top chock 1 and step 5, is rolling strip 3 between the roll surface of top working roll 2 and bottom working roll 4, and top working roll 2, bottom working roll 4 utilize roll change to link up with 6 pull-outs when taking out.
When working roll changed by needs as shown in Figure 2, first with compensating cylinder (not shown), top working roll 2 is lifted to extreme higher position, then the artificial top chock 1 at fore side and step 5 and place equal height cushion block 7 respectively between transmission side top chock 1 and step 5, then compensating cylinder is return, supported by an equal height cushion block 7 between the top chock 1 of every side and step 5; Then to be linked up with by roll change by roll change hydraulic cylinder and 6 top working roll 2, bottom working roll 4 to be pulled out together, top working roll 2 hangs away by overhead traveling crane, then is removed by equal height cushion block 7, is finally hung away by bottom working roll 4 with overhead traveling crane, then contrary when renewing roller.
With reference to Fig. 3, Fig. 4, the structure of the present invention's (after innovation) is in active side and fore side mount pad, be respectively arranged with top chock 1 and step 5, and top chock 1 and step 5 axial line be arranged in parallel up and down; Top working roll 2 and bottom working roll 4 is installed with respectively in top chock 1 and step 5, innovation is, a contour bearing pin 8 is fixedly installed respectively at step 5 upper surface of active side and fore side, the bottom surface of the corresponding top chock 2 at active side and fore side is provided with deep hole 9 and shallow bore hole 10, two contour bearing pins 8 can pack into two deep holes 9 simultaneously or two contour bearing pins 8 can pack into two shallow bore holes 10 simultaneously.
The schematic diagram of upper and lower working roll when rolling (as Fig. 3) after improving, contour bearing pin 8 is fixed on step 5 upper surface of both sides, two circular holes (deep hole 9 and shallow bore hole 10) are added in top chock 2 bottom surface of every side, during rolling work, contour bearing pin 8 correspondence is inserted in two darker deep holes 9, does not affect top working roll 2 and bottom working roll 4 normally works.When needs roll change, first with compensating cylinder (not shown), top working roll 2 is lifted to extreme higher position, two contour bearing pins 8 deviate from two deep holes 9, then link up with 6 from roll change hydraulic cylinder (not shown) by roll change and bottom working roll 4 is moved 150mm (controlling displacement by proximity switch) toward fore side, then compensating cylinder is return a segment distance, two contour bearing pin 8 correspondences are made to insert in two shallow bore holes 10 (as Fig. 4), now the roll surface of top working roll 2 and bottom working roll 4 does not contact, and by contour bearing pin 8, top working roll 2 and bottom working roll 4 are connected as a single entity, reposefully top working roll 2 together can be pulled out by pulling bottom working roll 4, top working roll 2 hangs away by overhead traveling crane, contour bearing pin 8 is not needed to remove, namely bottom working roll 4 hangs away by available overhead traveling crane, then contrary when renewing roller.
Structure of the present invention, when changing working roll, eliminates the artificial operating procedure of placing equal height cushion block and removing equal height cushion block, achieve the function of High-Speed Automatic roll change, roll change speed is fast, and hand labor intensity is low, substantially increase roll change speed, meet efficiently, rhythm of production fast.
