Description

Technical Field

[0001] The invention relates to the field of mechanical correction, in particular to a mechanical correction device for welding deformation of butt steel plates. Background Art

[0002] At present, a Chinese invention with a publication number of CN114393059B discloses a steel plate correction device, which includes: a bottom plate and a mounting plate fixedly connected to the upper surface of the bottom plate, the mounting plate is used to install components for steel plate correction; a driving component, the driving component includes an electric telescopic rod, a sliding rod, a driving plate, and a push plate, one end of the electric telescopic rod is fixedly connected to the bottom plate, the driving plate is fixedly connected to the other end of the electric telescopic rod, the two sliding rods are transversely penetrated at both ends of the driving plate, the push plate is fixedly connected between the two sliding rods, and the driving component is used to push the steel to move. The invention moves downward by squeezing the arc plate and the partition, and at the same time the partition pushes the pressing plate to move downward and stretches the first spring. Since the pressing plate squeezes the steel plate when it moves downward, the bent steel plate is squeezed and corrected; Although the existing correction device can repair the deformed steel plate by pressing the plate downward, there are still other problems during use, such as poor correction effect. The steel plate can be corrected by the pressure of the hydraulic press. Since the steel plate may have irregular deformation or bending, it may not be able to be completely corrected by relying solely on the pressure of the hydraulic press. At this time, it is necessary to cooperate with the knocking operation to further adjust the shape of the steel plate. When knocking, it is necessary to place an iron block on the knocking part and hold it with the hand, which has poor safety and does not have an automatic translation function. When the device corrects multiple welding deformations of a longer steel plate, since the correction components are in a fixed state and cannot be moved, personnel are required to manually pull the steel plate, which is time-consuming and labor-intensive. In order to solve the above-mentioned problems, we propose a mechanical correction device for welding deformation of butt steel plates. Summary of the invention

[0003] The purpose of the present invention is to provide a mechanical correction device for welding deformation of butt steel plates, which solves the problem that the existing correction device has poor correction effect and does not have automatic translation function.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions: A mechanical correction device for welding deformation of butt-jointed steel plates, comprising a base and a fixing mechanism, wherein a threaded rod is rotatably connected inside the base, a first motor is fixedly sleeved at the other end of the threaded rod, a first threaded plate is threadedly connected to the surface of the threaded rod, connecting plates are welded on both sides of the first threaded plate, through grooves are provided on both sides of the base, a support plate is bolted to the other end of the connecting plate, a top plate is provided on both sides of the base, a top plate is bolted between the two support plates, a hydraulic jack is arranged at the bottom of the top plate, two fixing plates are arranged at the top of the base, opposite sides of the two fixing plates are bolted to the support plate, a slide rail is bolted to the bottom of the fixing plate, a fixing cylinder is symmetrically arranged at the bottom of the fixing plate, a slider slidably connected to the slide rail is welded to the top of the fixing cylinder, a fixing block is arranged inside the fixing cylinder, a limit spring is bolted between the bottom of the fixing block and the slider through a spring fixing sheet, a connecting rod is welded to the bottom of the fixing block, a pedal is welded to the other end of the connecting rod, and an iron block is embedded at the top of the pedal.

[0005] The above technical solution can have automatic translation and cleaning functions, ensure the cleanliness of the steel plate surface, reduce the burden of manual pushing and pulling of the steel plate by personnel, have good flexibility, and can achieve good correction effects. The operation is simple and convenient. The accuracy of correction can be improved through initial large-area correction and subsequent fixed-point correction, and it is highly practical.

[0009] By adopting the above technical scheme, through the arrangement of the installation frame, the reciprocating screw, the second motor, the second threaded plate and the brush plate, a surface cleaning function can be achieved. The welding deformation of the steel plate that needs to be corrected is pushed into the inside of the hydraulic jack, and then the second motor is started to drive the reciprocating screw to rotate. When the reciprocating screw rotates, it will drive the second threaded plate and the brush plate to reciprocate left and right with the cooperation of the second limit rod. The brush plate will sweep away impurities and dust on the surface of the steel plate when it reciprocates.

[0010] The present invention is further configured as follows: two first limiting rods are arranged through the front side of the first threaded plate, and both ends of the first limiting rods are welded to the inside of the base.

The extended end of the hydraulic jack is extended to perform preliminary correction on the steel plate extrusion and then reset. Then the position of the iron block is adjusted to be located above the correction position, and the pedal is moved downward by holding a hand hammer and stepping on it with the foot.
