Abstract
The utility model belongs to special equipment for metal structure machining. A beam and a column in the structure are stress means. In fabrication, due to welding hot deformation, the dimension and the stress are caused not to meet the requirement. In order to solve the problem, a pre-bending deforming machine is designed. The pre-bending deforming machine is composed of a main drive part and an electric screw down part which is formed by that a worm and a worm wheel are driven by a motor through a belt, and are connected with the upper end of a lead screw through a transmission sleeve; the lower end of lead screw is connected with a pressing wheel frame of which the lower end is provided with a pressing wheel; the pressing wheel frame makes the up-and-down movement corresponding to a machine frame plate. The main drive part is formed by that a main axle is driven to rotate by the motor through a belt pulley to make a steel plate positioned on the upper side of the main axle make the front and back movement. The steel plate is arranged at the middle position of the main axle; the pressing wheel is positioned above the steel plate, and is vertical to the length direction of the main axle and lies in the deepest position of the concave part of the main axle simultaneously. The utility model is suitable for the pre-bending deformation on the steel plate of which the thickness is below 30 mm and the width is smaller than 800 mm.
Description
The utility model belongs to the special equipment that the metal structure processing industry is used.In steel-structure factory building, framework, girder steel, post are main primary structure members, and in the manufacturing process, often owing to the sweating heat distortion makes its appearance and size and force structure undesirable.
Main rigid fixation and the heat straightening method of adopting prevented the system distortion in the industry at present.The former is meant and weldment is fixed on the rigid platfor or welds under welding jigs and fixtures clamp, after the latter is meant that welding deformation occurs, utilizes workpiece local heat and cooled contraction are caused the distortion that new distortion deemphasis has just produced.These two kinds of ways exist following shortcoming, and 1, cause the waste of material, the steel of using as anchor clamps, the combustion gas of correcting usefulness etc.; 2, have certain blindness, passivity, can not fundamentally solve problem on deformation; 3, increase labour intensity, reduced efficiency.
The purpose of this utility model is to utilize the reversible deformation principle, fundamentally solves the welding deformation problem, thereby improves the making quality of beam column of steel structure, designs a kind of sheet material prebuckling texturing machine.Promptly the flange plate to the girder steel post that sweating heat distortion might occur carries out reciprocal prebuckling distortion (deflection can utilize handbook to find) in the commissure, like this, in the welding process of itself and web, under the effect of thermal deformation, just can recover straight, guarantee good making quality.
Characteristics of the present utility model for stable, efficient, cost is low, generalization is strong, in the compacting reversible deformation, the internal stress of steel plate is had the evacuation effect, thereby reduced the possibility of side sway and distortion, has improved the making quality greatly.
The utility model is mainly realized by following structure
Constitute by main drive gear and electronic screw-down two parts.Electronic screw-down is made up of motor (9), belt (8), belt pulley (6), worm gear (10), worm screw (7), leading screw (2), pinch roller frame (3), wheel pressing shaft (5), pinch roller (4), frame plate (1); Motor drives the belt pulley that is fixed with worm screw by belt, the worm gear that drives by worm screw is fixed on the frame plate top, and is connected by drive sleeve and leading screw upper end, the leading screw lower end connects a gate-type pinch roller frame, in the pinch roller frame lower end by fixing pinch roller of wheel pressing shaft installation of the horizontal placement on it; The gate-type pinch roller frame moves up and down by the relative frame plate of chute at its edge;
Transmission mechanism is made up of motor (23), belt pulley (21), reductor (20), shaft coupling (24) and main shaft (17); Motor drives main shaft by belt pulley, reductor and shaft coupling and rotates, and the steel plate that is in above the main shaft is done seesawed; This main shaft is middle recessed formula axle, and the recessed degree of depth equals the pinch roller maximum reduction;
To be placed main axis length direction centre position by the steel plate that clod wash is out of shape, pinch roller is positioned at by the top of clod wash deformed steel flat, and is vertical with the main axis length direction simultaneously and be in the recessed bosom of main shaft.
Describe in detail below in conjunction with accompanying drawing
Its operation of sheet material prebuckling texturing machine equipment of the utility model design comprises two cover transmission systems, the one, form by motor (23), belt pulley (21), reductor (20), shaft coupling (24) and main shaft (17); Motor drives main shaft by belt pulley, reductor and shaft coupling and rotates, and the steel plate that is in above the main shaft is done seesawed; This main shaft is middle recessed formula axle, and the recessed degree of depth equals the pinch roller maximum reduction; Be that the motor I passes to reductor by belt pulley, drive spindle operation, the steel plate of the need compacting on the traction main shaft is to forward and backward motion; The 2nd, the electronic screw-down of forming by motor (9), belt (8), belt pulley (6), worm gear (10), worm screw (7), leading screw (2), pinch roller frame (3), wheel pressing shaft (5), pinch roller (4), frame plate (1); Motor drives the belt pulley that is fixed with worm screw by belt, the worm gear that drives by worm screw is fixed on the frame plate top, and is connected by drive sleeve and leading screw upper end, the leading screw lower end connects a gate-type pinch roller frame, in the pinch roller frame lower end by fixing pinch roller of wheel pressing shaft installation of the horizontal placement on it; The gate-type pinch roller frame moves up and down by the relative frame plate of chute at its edge; To be placed main axis length direction centre position by the steel plate that clod wash is out of shape, pinch roller is positioned at by the top of clod wash deformed steel flat, and is vertical with the main axis length direction simultaneously and be in the recessed bosom of main shaft.To be the motor II drive worm screw, worm gear, drive sleeve by belt pulley rotates, and by threaded engagement, screw mandrel is moved up and down, thereby pinch roller is risen or depresses, and grasps volume under pressure by scale, can make steel plate produce rational anti-deformation.
When the sheet material prebuckling texturing machine of the utility model design uses, at first the steel plate of needs processing is put on the travelling carriage, one end is aimed at the main shaft center line, makes steel plate placed in the middle by adjusting gear wheel, and second, press down system starts the machine, pinch roller presses down and makes steel plate produce desirable deflection, and the 3rd, start main transmission, make main shaft drive steel plate and travel forward, thereby make the whole piece steel plate obtain desirable reversible deformation.
As making length in making is 6 meters, height is 1.2 meters, the wide 300mm in wide 400mm lower flange, top flange, thick 20mm, when material is the girder steel of 16Mn, adopt the sheet material prebuckling texturing machine of the utility model design to carry out reversible deformation, processing capacity is 8.45mm through consulting handbook, adopts Lincoln weld to weld after the assembly unit moulding, postwelding after testing, straight error is in 1mm, and other errors reach the excellent product standard less than 4mm.
