Description
Technical field
The utility model belongs to plant equipment field, is specially a kind of three rolls plate bending machine that rolls cylinders with small diameter.
Background technology
Veneer reeling machine is the moulding lathe that sheet material is carried out to continuity point bending, has the O of rolling type, U is capable, the function of the difformity sheet materials such as multistage R.Veneer reeling machine is widely used in the industries such as petrochemical industry shipbuilding, pressure vessel, machine-building.
Veneer reeling machine drives twice roller gear engagements to rotate by the final-stage gear of main gear reducer, provide moment of torsion for rolling sheet material, by pressing down of top roll and rotatablely moving of lower roll, make metallic plate through multi-pass continuous bend, produce permanent plastic deformation, be rolled into required shape.The existing market demand is a lot of to rolling cylindrical workpieces, tradition veneer reeling machine is in order to reach nominal torque and top roll plus-pressure, upper roller diameter is conventionally larger, the cylindrical shell minimum diameter size of the sheet material that rolls is subject to the restriction of roller diameter, and traditional veneer reeling machine rolls 1.8-2.5 that cylindrical shell minimum diameter is generally roller diameter doubly.Therefore, how under nominal torque and stressed prerequisite, reduce minimum drum diameter and become and change the large problem that field need to solve ensureing to reach.
The spindle nose stiff end of traditional upper roller of press brake stretches out major axis in addition, and there is the structure of pushing down spindle nose on major axis top, and after reel completes, the overturning of upper roller shaft head overturning seat, takes off cylinder after top roll rising perk.The shortcoming of this structure is: complex structure burden, the structure that spindle nose is pushed down on major axis top needs often to regulate, and regulates bad impact normally to roll work, inefficiency.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, easy to operate, can roll the small-sized veneer reeling machine of cylinders with small diameter.
The technical scheme that realizes above-mentioned purpose is: three rolls plate bending machine, comprise chassis, support, two lower rolls and a top roll, the left and right sides on chassis is separately installed with support, two lower rolls are installed on support, one side of support is provided with the actuating unit that drives two lower roll rotations, the upper center of two side stands is respectively arranged with bearing block, top roll is supported on the bearing block of two side stand upper ends, top roll away from actuating unit one end bearing block be turnover type bearing block, the lower end of the bearing block of two side stand upper ends is respectively arranged with the drive unit that drives bearing block to move both vertically up and down, it is characterized in that: top roll lateral cross section is the fusiformis that middle part diameter is greater than two ends diameter, on two lower roller center distances, the 2.2-2.7 of roller diameter doubly.
Top roll lateral cross section of the present utility model is the fusiformis that middle part diameter is greater than two ends diameter, while being used for rolling sheet material, the distortion of working roll middle part is carried out to mechanical compensation, on two lower roller center distances, the 2.2-2.7 of roller diameter doubly, make to roll and when work is carried out, rolled the more effective contact up-down rollers of workpiece, allow the minimum diameter cylindrical shell that rolls out the top roll of more fitting, the small-sized three rolls plate bending machine that rolls cylinders with small diameter the utility model proposes roll cylindrical shell minimum diameter and can reach 1.1 times of top roll maximum diameter.
The utility model has been cancelled the major axis that the fixed bearing block of top roll one end stretches out and major axis top and has pushed down the structure of spindle nose, while getting rolled workpiece, directly be positioned between the up-down rollers of fixed bearing block one side of upper roller shaft head with a round bar, by the overturning of top roll turnover type bearing block, decline top roll, takes off cylinder after perk.This method of getting workpiece reduces costs, and increases work efficiency, and has simplified the structure of equipment.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the structural representation of top roll.
Detailed description of the invention
As shown in Figure 1, the utility model comprises chassis 1, support 2, two lower rolls 3 and top rolls 4, the One On The Chassis left and right sides is separately installed with support 2, two lower rolls 3 are installed on support 2, one end of two lower rolls 3 connects respectively the first gear 8, and a side of support 2 is provided with the actuating unit 10 that drives two lower roll rotations, and actuating unit 10 comprises motor 5 and decelerator 6, the output of decelerator connects the second gear 9, the second gears 9 and engages with the first gear 8 of two lower roll 3 ends respectively.
The upper center of two side stands 2 is respectively arranged with bearing block 7, top roll is supported on the bearing block 7 of two side stand upper ends, top roll 4 near actuating unit 10 one end bearing block 7 be fixed bearing block, top roll 4 away from actuating unit 4 one end bearing block 7 be turnover type bearing block, it is identical with the driving device structure of existing veneer reeling machine that the lower end of the bearing block 7 of two side stand 2 upper ends is respectively arranged with the drive unit 9(drive unit 9 that drives bearing block 7 to move both vertically up and down, do not repeat them here).
Top roll 4 lateral cross section are middle part diameter and are greater than the fusiformis of two ends diameter, and the 2.2-2.7 that two lower roll 3 centre-to-centre spacing are upper roller diameter doubly.
The utility model has been cancelled the major axis that the fixed bearing block of top roll one end stretches out and major axis top and has pushed down the mechanism of spindle nose.
