Background technique
Plate bending rolls is a kind of standard equipment that sheet metal is rolled to tubular, arc or other shape workpiece.Existing three rolls plate bending machine bottom roll bearing block is two side by side opposite opened four bolts positive plain bearing housing, bearing base and bearing cap horizonally splits.This horizonally split formula structure, when three rolls plate bending machine was worked, bearing cap also was subject to the effect of loading force simultaneously, sometimes caused the attachment bolt fracture of bearing cap and bearing base, affected the working life of equipment.
Summary of the invention
The purpose of this utility model provides the three rolls plate bending machine lower roll cast-steel chock that a kind of two side by side opposite opened six bolts tiltedly slide.
The purpose of this utility model is achieved in that a kind of three rolls plate bending machine bottom roll bearing block, comprise base, bearing cap and bolt, bearing cap by bolt-locking on base, it is characterized in that: the end face that base is connected with bearing cap is oblique, be oppositely arranged, the angle of its end face and horizontal plane is 20-30 °, and the vertical center line of both ends of the surface intersects.
The bottom of described base is provided with material reducing groove, base plate through holes, and the end face both sides that are connected with bearing cap are provided with base screw, base seam and positioning pin hole, and the two ends of bearing hole are provided with bearing shell thrust groove.
The top of described bearing cap is provided with lubricated screw, the bearing cap seam that be provided with the bearing cap through hole corresponding with the base screw with end face both sides that base connects, agrees with mutually with the base seam and join the positioning pin hole of brill with base.
Described bolt adopts double end attachment bolt and double nut.
Compared with prior art, the utility model has the advantages that:
1, the utility model arranges bearing base in opposite directions with the end face that left and right bearing cap is connected, and the angle of its end face and horizontal plane is 25-30 °, can improve the stress of bearing support, improves the working life of bearing support.
2, the utility model arranges respectively seam on bearing cap and end face that bearing base is connected, can prevent the changing of the relative positions between bearing cap and the bearing base, and be convenient to install.
3, the utility model adopts respectively six roots of sensation double end attachment bolt and double nut with left and right bearing cap and bearing base locking, and its intensity is strengthened.
4, the utility model is provided with bearing shell thrust groove at the two ends of base bearing hole, and bearing shell thrust groove and the assembling of bearing shell two end boss can prevent the bearing shell axial float.
5, the utility model is provided with lubricated screw above bearing cap, guarantees the lubrication effect of bearing shell and between centers.

Among the figure: base 1, material reducing groove 11, base plate through holes 12, base screw 13, base seam 14, positioning pin hole 15, bearing shell thrust groove 16, bearing cap 2, lubricated screw 21, bearing cap through hole 22, bearing cap seam 23, bolt 3.
Embodiment
The utility model is described in further detail by reference to the accompanying drawings for following embodiment.
See figure: a kind of three rolls plate bending machine bottom roll bearing block comprises base 1, bearing cap 2, bolt 3.Bearing cap 2 is left and right two, left and right bearing cap 2 is locked on the bearing hole on the base 1 by bolt 3 respectively, base 1 is oblique with the end face that left and right bearing cap 2 is connected, be oppositely arranged, the angle of its end face and horizontal plane is 20-30 °, the angle of present embodiment end face and horizontal plane is set to 25 °, and the vertical center line of both ends of the surface intersects.The oblique sliding motion structure of this opposite opened can improve the stress of bearing support widely.
On the basis that guarantees base 1 intensity, the bottom of base 1 is provided with material reducing groove 11, the base plate through holes 12 that is connected with the three rolls plate bending machine fuselage, the end face both sides that are connected with bearing cap are provided with base screw 13, base seam 14 and join the positioning pin hole 15 of brill with bearing cap.Bearing hole two ends on base 1 are provided with bearing shell thrust groove 16, and bearing shell thrust groove 16 and the assembling of thrust side, bearing shell two ends flange prevent the bearing shell axial float.Base screw 13 is set to a pair of at least, and present embodiment arranges three pairs.
The top of bearing cap 2 is provided with lubricated screw 21, guarantees the lubrication effect of bearing shell and between centers.The bearing cap seam 23 that the end face both sides that bearing cap 2 and base connect are provided with the bearing cap through hole 22 corresponding with base screw 13, agree with mutually with base seam 14 and join the positioning pin hole 15 of brill with base.
During installation, first that bearing cap through hole 22 is corresponding with base screw 13, bearing cap seam 23 agrees with mutually with base seam 14, adds locating stud in the positioning pin hole 15, bolt 3 is passed bearing cap through hole 22 again and screws in base screw 13 until locking.The setting of base seam 14 and bearing cap seam 23 prevents the changing of the relative positions between base 1 and the bearing cap 2, is convenient to simultaneously the installation of bearing cap 2.The setting of positioning pin hole 15 and locating stud further prevents the changing of the relative positions of bearing cap 2 and base 1.
