Description
Technical Field
The invention relates to the technical field of straightening machines, in particular to a strip-shaped steel plate straightening machine.
Background
In order to improve the bending precision, a workbench below the sliding block is designed into a compensation mechanism capable of compensating the deformation, and a strip-shaped steel plate with higher straightness is needed in the compensation mechanism, so that the strip-shaped steel plate needs to be straightened by a straightening machine in the process of manufacturing the compensation mechanism; the existing straightening machine has a complex structure and higher cost.
Disclosure of Invention
The invention aims to solve the problems of complex structure and higher cost of the existing straightening machine, and provides a long-strip-shaped steel plate straightening machine which is simple in structure, convenient to operate and particularly suitable for straightening long-strip-shaped steel plates.
The specific scheme of the invention is as follows: a strip-shaped steel plate straightening machine comprises a rectangular workbench, wherein supporting legs are arranged at four corners of the bottom of the workbench, the top surface of the workbench is a working plane, two grooves are formed in two sides of the top of the workbench, a portal frame capable of moving along the grooves is arranged in the two grooves, two roller supports are respectively arranged on two sides of two upright posts of the portal frame, a wheel shaft is fixedly arranged on each roller support, the wheel shafts extend towards the workbench, the end parts of the wheel shafts are provided with rollers through bearings, the rollers roll in the grooves, an oil cylinder is arranged in the middle of a cross beam at the top of the portal frame, through holes are formed in the cross beam at two sides of the oil cylinder, linear bearings are arranged in the through holes, a connecting plate is fixedly arranged at the lower end of a piston rod of the oil cylinder, two; a rack is arranged on one side surface of the workbench along the whole length, a motor and a speed reducer are fixedly arranged on the upright post of the portal frame corresponding to the rack, and a gear meshed with the rack is arranged at the output end of the speed reducer.
The bottom ends of two side surfaces of the workbench are provided with guide beams, two upright posts of the portal frame are fixedly provided with guide wheel brackets corresponding to the guide beams, and the guide wheel brackets are provided with guide wheels rolling along the guide beams.
The working principle of the invention is as follows: during actual operation, a strip-shaped steel plate to be straightened is lifted to a workbench, two equal-height cushion blocks are padded at two ends below the steel plate, another detection block with the height equal to the two cushion blocks is prepared, a motor is started to move a portal frame to a point needing to be straightened on the steel plate and then the portal frame is stopped, an oil cylinder acts to enable a pressure head to descend to press the steel plate downwards for a certain distance, a piston rod retracts, the detection block is taken to detect whether a gap exists below the straightening point of the steel plate, and if the gap exists, the steel plate is pressed downwards again for straightening until the straightness at the position reaches the requirement.
Compared with the prior art, the invention has the following advantages: simple structure, low cost and convenient operation, and is particularly suitable for straightening the strip-shaped steel plate.
