Abstract
The invention belongs to the technical field of mechanical engineering and relates to a two-stage side direction transmission three-roller mill. The system comprises a machine base transmission side cover, a machine base, a machine base roller side cover, a transmission shaft, rollers, a roller seam adjusting mechanism and roller bearing pedestals. According to the two-stage side direction transmission three-roller mill, transmission power is input in the side direction in a two-stage manner. When the roller seam is adjusted, the rollers are perpendicular to a connecting line of the center of a gear of the transmission shaft and the center of a gear of the rollers. After the roller seam is adjusted, the difference of the variable quantities of the central moment of the two gears is within the tolerance range allowed by the central moment. The three roller bearing pedestals moving perpendicular to a rolled piece and the roller seam adjusting mechanism are designed and arranged in the manner that the three roller bearing pedestals and the roller seam adjusting mechanism are matched with the adjusting roller seam adjusting mode. The roller seam adjusting mechanism synchronously drives a wedge block to move so that the roller seam can be increased or decreased. According to the two-stage side direction transmission three-roller mill, transmission power is input on the side faces of the three rollers, a C-shaped module is omitted, power input of the mill is simplified, and the equipment weight and energy consumption are reduced.
Description
Invention field
The invention belongs to mechanical engineering technical field, relate to a kind of two-stage side direction transmission three-high mill.Be applicable to the rolling of sheet metal, wire rod, tubing, be also applicable to the low temperature temperature-controlled rolling of metal.
Background technology
Three 120 °, roller milling trains are applied to the reducing-sizing mill of Bar Wire Product for 1954, and early stage three-roll mill roll gap can not adjust, and therefore need the quantity increasing frame for subsequent use.Until 1984, KOCKS is proposed RSB reducing-sizing mill, the frame of C pattern block center utilizes 3 inner eccentric bushings to drive roll to do eccentric motion to adjust roll gap, the power of frame relies on three the direction inputs of C pattern block, although this milling train achieves adjustment roll gap, cost is the increase in bulky C pattern block, and this not only increases burden to equipment investment, also because the prolongation of driving-chain makes the efficiency of equipment reduce, the too much consumption adding the energy.
Improve or cancel C pattern block, alleviating weight of equipment and reduce equipment investment, shorten long driving-chain, reduce the too much energy resource consumption therefore caused, be undoubtedly the requirement that market is improved prior art.

Detailed description of the invention
Roller. redress roll gap is moved in the direction that core of the present invention is perpendicular to the two travelling gear lines of centres, and for coordinating the mode of this adjustment roll gap, three roll chocks perpendicular to rolled piece movement (7) of design arrangement, and roll-separating mechanism (6).As shown in Fig. 7 embodiment 1, during adjustment roll gap, roll (5) is perpendicular to the line of centres with power transmission shaft (6), a mobile segment distance within the scope of roll gap regulation, depart from former two meshing gear lines of centres, the gear of roll (5) forms a new line on new central point with the gear centre of power transmission shaft (4), this line and the former line of line in the heart form a right angled triangle with the segment distance adjusting roll gap movement, the difference of hypotenuse and adjacent side is exactly the center square difference in change formed after adjustment roll gap, because the distance adjusting roll gap is generally less than 15mm, therefore, the difference of triangle adjacent side and hypotenuse, namely the engagement center difference in change of the gear of power transmission shaft (4) and the gear of roll (5) is in the square design tolerance allowed band of center.
Power transmission shaft (4), roll (5), roll-separating mechanism (6), roll chock (7) are fixed in the rear entirety of assembling by support transmission side cover (1) of the present invention, support (2), support roll side cover (3).Three roll chocks (7) are in 120 ° of distributions, the plane of side and support (2) is fitted, when needs are to large adjustment roll gap, the motor (6.0) of roll-separating mechanism (6) drives bevel gear (6.1) to rotate, bevel gear (6.1) drives bevel gear (6.2) to rotate, gear (6.3) and bevel gear (6.2) coaxial rotation driving gear wheel rim (6.4) rotate, gear ring (6.4) driving pinion (6.6) rotates, worm screw (6.7) and pinion (6.6) coaxial rotation also drive worm screw (6.8) and leading screw (6.9) to rotate, leading screw (6.9) drives square nut (6.10) to pull out wedge (6.5), the Compress Spring (7.1) of balance roll chock (7) is by roll bearing seat (7) jack-up.
When needs are to little adjustment roll gap, motor (6.0) drives wedge (6.5) inwardly to slide by driving-chain, be pressed against the boss of roll chock (7), the Compress Spring (7.1) of balance roll chock (7) is compressed, and roll gap is diminished by adjustment.Corresponding with three roll chocks (7) 120 ° of 3 wedges (6.5) of roll-separating mechanism (6) distribute and arrange, 3 wedge (6.5) synchronizing movings.
For larger roll gap adjustment distance can be adapted to, as shown in Figure 7:
Embodiment two of the present invention, power transmission shaft and roll can adopt oblique layout.
Embodiment three of the present invention, roll rotates around center transmission shaft, and gears meshing center square remains unchanged.
