One end of a pinch roll bearing block is connected with a turnover cross beam which is connected with a rack through a pin shaft and a gasket, the other end of the bearing block is connected with a connecting rod through a pin shaft, the connecting rod is provided with a gasket and a disc spring capable of adjusting the pin force, a flange and a sleeve are fixed on the rack through a connecting nut and a double-screw bolt, an adjusting screw rod is screwed in the flange, a locking nut is screwed in the adjusting screw rod and on the upper part of the flange, a conical-face washer is arranged on the upper part of the adjusting screw rod and the top of the connecting rod, a spherical-face washer is tightly pressed on the conical-face washer through an adjusting nut, a ruler is arranged on the flange, the interior of the connecting rod is provided with an oil channel and the head part of the connecting rod is provided with a direct-through type oil cup. According to the utility model, the linear sliding of an upper pinch bearing block is changed into swinging, an air cylinder or a hydraulic oil cylinder are omitted, and adjustable elastic force is produced through the disc spring and is amplified into pinch force by utilizing a lever principle, so that plates of different thicknesses can be adapted without manual adjustment.
Description
Technical field
The utility model relates to metallurgical technology field, particularly a kind of last clamping and conveying device that is used for the adjustable power of pinching of fast open form roll leveller.
Background technology
In the modern metallurgy industry, clamping and conveying device is widely used, and is used with distinct device, can play and wear band, turn to, form effects such as tension force, carrying roller.On roll leveller, clamping and conveying device can improve bite condition.
The common structure of clamping and conveying device pinches under being fixing, on pinch and utilize cylinder or hydraulic jack and bottom pinch roll to produce clamping force.And mainly there is following defective in the existing clamping and conveying device of going up:
1, adopt air pressure or hydraulic control, clamping and conveying device needs constant voltage at work, and is higher to the seal request of whole pipeline, and constant pressure, and the power of pinching can't be regulated; Pinch the sheet material of different-thickness, need the manually-operated adjustment, influence production efficiency.
2, bearing block moves along cylinder or hydraulic jack axis, between bearing block and the frame slide plate is installed, and need locate the pinch roll axis direction.Because the bearing block installation accuracy requires high, the installation adjustment difficulty of slide plate, the filling lubricant grease is more frequent, and the wearing and tearing back reduces precision, needs periodic replacement, has increased and has safeguarded use cost.
Summary of the invention
For overcoming the deficiency of prior art, the goal of the invention of the utility model is to provide a kind of last clamping and conveying device of the adjustable power of pinching, to realize convenient purpose of regulating the power that pinches.
For realizing above-mentioned purpose; Pinch roll bearing block one end of the utility model is connected with the upset crossbeam, is connected with bearing pin, pad between overturn crossbeam and the frame, and it is characterized in that: the bearing block other end connects through bearing pin with connecting rod; Pad is housed on the connecting rod and can regulates the dish spring that pinches the power size; Flange and sleeve pipe utilize attaching nut, double threaded screw to be fixed on the frame, and adjusting screw(rod) is spun in the flange, on adjusting screw(rod), the top of flange is rotary with locking nut; At the top of adjusting screw(rod), the top of connecting rod taper faced washer is housed; Spheric washer is pressed on the taper faced washer with adjusting nut, and scale is housed on the flange, and connecting rod inside is opened oil duct and at head the through type lubricating cup is installed.
The utility model will on pinch bearing block linear slide change swing into; Cancellation cylinder or hydraulic jack produce adjustable elastic force through the dish spring, utilize lever principle to form the power that pinches with the elastic force amplification of dish spring and with bottom pinch roll; Sheet material that can the self adaptation different-thickness need not artificial adjustment.

Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Like Fig. 1, shown in Figure 2; Bearing block 16 1 ends of the utility model pinch roll 17 are connected with upset crossbeam 18, are connected with bearing pin 19, pad 1 between overturn crossbeam 18 and the frame, and bearing block 16 other ends connect through bearing pin 15 with connecting rod 14; Pad 2 12 is housed on the connecting rod 14 and can regulates the dish spring 13 that pinches the power size; Flange 11 utilizes attaching nut 4, double threaded screw 5 to be fixed on the frame with sleeve pipe 6, and adjusting screw(rod) 3 is spun in the flange 11, on adjusting screw(rod) 3, the top of flange 11 is rotary with locking nut 10; At the top of adjusting screw(rod) 3, the top of connecting rod 14 taper faced washer 8 is housed; Spheric washer 7 usefulness adjusting nuts 2 are pressed on the taper faced washer 8, and scale 9 is housed on the flange 11, and connecting rod 14 inside are opened oil duct and at head through type lubricating cup 1 are installed.
Rotation adjusting screw rod 3, through pad 2 12 compact disc springs 13, elastic force is tightened locking nut 10 after reaching requirement; Balanced in order to guarantee elastic force, connecting rod 14 has been installed spheric washer 7 and taper faced washer 8, and uses double nut 2 fastening; Connecting rod 14 moves along axis in the adjustment process, and pinch roll bearing block 16 1 ends connect with upset crossbeam 18, and elastic force becomes swing with the slip of bearing block 16; The swing center of circle is the axis of upset crossbeam 18; Through rotation adjusting screw rod 3 compact disc springs 13 strokes, thus the power of depressing of change connecting rod 14, and then the change top pinch roll pinches the power size.Be fixed with scale 9 on the flange 11, can converse the size of the power of pinching according to the displacement of regulating.
The utility model has been simplified former slide plate and pinch roll axis positioner; Simultaneously; Bearing block 16 other ends connect through bearing pin 15 with the connecting rod 14 that has many group complex form dish springs 13, replace original cylinder or hydraulic jack, and save control corresponding device and pipeline.
