Description
Technical field
The invention belongs to a kind of pinch machine technical field, and in particular to a kind of pinch machine for being used to produce coil of strip.
Background technology
The roller that send for being presently used for the pinch machine of production coil of strip uses upper and lower 2 pinch rollers, top pinch roll can on move down
Dynamic, bottom pinch roll is fixed on base with bearing block.Pinch machine roller spacing needs to carry out phase according to the different-thickness of production steel plate
It should adjust.If being adjusted according to the tandem mill roller spacing that non-ferrous metallurgical equipment custom uses and power transmitting mechanism being designed,
It is then excessive there are cost, the shortcomings of floor space is excessive.The scope adjusted in view of roller spacing is smaller, some classes in production practices
Like adjusting mechanism using lengthening the transmission of tooth Involute Helical Gears, which has compact-sized, low cost, can be certain
The advantages that two roller center of scope endoadaptation is away from change.But during due to two roller centers away from changing, it is difficult to ensure that gear can connect
Resume dynamic, thus produce shock and vibration, gear teeth serious wear, rotational noise is big, and service life is short.
The content of the invention
The technical problems to be solved by the invention are to provide one kind in view of the above shortcomings of the prior art to be used to produce coil of strip
Pinch machine, its with overall structure simple and compact, operate steadily that reliable, noise is low, service life is long, cost performance height etc. is excellent
Point.
To realize above-mentioned technical purpose, the technical solution that the present invention takes is：
A kind of pinch machine for being used to produce coil of strip, wherein：Including rack, motor, retarder, the second idle pulley, band sliding block
Seat bearing, adjusting screw rod, T-nut, spring, driven wheel, driving wheel, top pinch roll, bottom pinch roll, counting pinion gear, counting
Device, the first idle pulley, lower link and upper connecting rod, the motor are fixedly mounted on retarder, the reducer output shaft
It is connected with bottom pinch roll right end, the bottom pinch roll left end is installed in rack by bearing, and the driving wheel fixes peace
Mounted in bottom pinch roll right end, the driven wheel is installed on top pinch roll right end, and the top pinch roll both ends all pass through bearing
On band take-up housing bearing, the T-nut is installed on adjusting screw rod, and the adjusting screw rod lower end is installed on band
On take-up housing bearing, the counting pinion gear engages with driving wheel and counts pinion gear on counter, the meter
Number device is installed in rack, and described upper connecting rod one end is installed on bottom pinch roll right end and the upper connecting rod other end is lazy installed in second
On wheel, described lower link one end is installed on the second idle pulley and the lower link other end is installed on the first idle pulley, and described the
One idle pulley is engaged with driving wheel, and second idle pulley is engaged with the first idle pulley, and the driven wheel is engaged with the second idle pulley, institute
The spring one end stated is installed on band take-up housing bearing and the spring other end is installed in rack.
To optimize above-mentioned technical proposal, the concrete measure taken further includes：
Adjustable supports are installed on the bottom surface of above-mentioned rack.
Above-mentioned band take-up housing bearing is installed on line slideway and line slideway is installed in rack.
Above-mentioned rack is welded using section bar.
The present invention carries out the adjusting of roller spacing, Gears-Connecting Rod Mechanism by the way of being combined with take-up housing bearing with spring
It is driven power transmission.Top pinch roll is installed on band take-up housing bearing, keeps steady by the balance between gravity and spring force
Fixed operating position.Adjust the position that T-nut drives adjusting screw rod to move up and down adjustable bands take-up housing bearing, top pinch roll
Position respective change therewith, realize the adjusting of two pairs of rollers spacing.During Plate Production, the initial roll gap in equilibrium state
Less than steel plate actual (real) thickness, top pinch roll is lifted up by steel plate after biting roll gap, and spring is subject to compression to produce downward elasticity
Power, conducting oneself with dignity to produce jointly with top pinch roll pinches power.In the case where change occurs in steel plate thickness, spring stress changes,
Corresponding flexible, roll gap and pinch power can be adjusted automatically within the specific limits.When steel plate thickness increase, top pinch roll is upward
Lift, roll gap increases therewith；Meanwhile spring-compressed, pinch power increase；Conversely, when steel plate thickness reduces, roll gap reduces, and pinches
Power reduces.
Motor drives driving wheel to rotate, while transfers power to driven wheel, principal and subordinate by the first idle pulley, the second idle pulley
The speed such as driving wheel holding reversely rotate, and form pinch machine double drive roll structure.The second idle pulley of Gears-Connecting Rod Mechanism floats, the
Connected, ensured first, second during roller spacing adjusts by connecting rod between two idler shafts and the first idler shaft, follower shaft
Centre-to-centre spacing between the centre-to-centre spacing of idle pulley and the second idle pulley and driven wheel remains unchanged.Top pinch roll surface is coated with one layer of rubber
Glue-line, can avoid to causing to damage to steel plate structure since steel plate thickness changes；Pass through the deformation of rubber during pinch
The defects of extruding steel plate, can remove issuable burr in production process.
The speed of pinch roller is measured by the rotating speed of counting gear, and feeds back to speed control system.Speed control uses
Zero current control principle：According to the deviation of the basic value of zero current adjuster, acceleration and deceleration current value and pinch roller current feedback values
The speed preset of pinch roller is adjusted, and makes the electric current of pinch roller be " zero ", ensures that pinch roller motor is in micro- motoring condition.
The advantage of the invention is that it is following some：It is simple in structure, have overall structure simple and compact, operate steadily it is reliable etc.
Advantage is, it can be achieved that the job requirement that upper bottom pinch roll constant speed rate reversely rotates.
