Problems solved by technology

[0002] In the process of sawing the steel plate with the circular saw, the internal stress will change sharply and have no direction, which will cause irregular deformation of the saw kerf, resulting in the phenomenon of knife clamping
The usual method is: 1. Install an oil cylinder on the side of the sub-material, and install a pressure block at the front end of the piston rod of the oil cylinder to directly press the side of the sub-material to prevent the sub-material from deforming towards the master material. However, the internal stress of the steel plate is very large, and The pressure of the oil cylinder is constant, and the internal stress of the deformation of the sub-material is often greater than the pressing force of the oil cylinder, and there is a large gap between the piston rod and the pressure block of the oil cylinder...

Method used

A kind of stroke of the present invention effectively prolongs the sub-material wedge side top structure, through the clamping assembly 3 that is mutually vertical and separated from the locking assembly 2, and uses the wedge rod 23 and the propelling cylinder 13 of lengthening, the wedge The rod 23 and the propulsion cylinder 13 are arranged at a position far away from the steel plate to avoid the parts of the sawing machine and the saw blade. The third mounting seat 31 close to the steel plate is small in size, thereby lengthening the effective stroke of the side jacking structure of the wedge block and making the jacking The tight position of the rod 32 is closer to the saw kerf. During use, when the steel plate is put in place, the piston rod of the propulsion cylinder 13 pushes the wedge rod 23 to move, and drives the push rod 24 to move in a direction perpendicular to the wedge rod 23. 32 protrudes and presses against the side of the sub-material, wherein the top of the ejector rod 32 is provided with a top 321, which can be pushed into the surface of the sub-material to better prevent its deformation and enhance the effect of side pushing, while the wedge rod 23 and the push rod 24 are in contact Both surfaces of the two sides are provided with inclined surfaces of the same slope, and are self-locking angles to ensure that the ejector rod 32 will not be retracted due to the deformation force of the steel plate. At the same time, the ejector rod 32 is a cuboid with good guiding rigidity and will not The rotation occurs, thereby effectively overcoming the deformation force of the sub-material, reducing the probability of knife clamping and equipment failure rate, and prolonging the service life of the saw blade. The wedge bar in this mechanism is very long, but it is far away from the steel plate, so it will not interfere with the parts and saw blades of the circular sawing machine, and the jacking assembly 3 has a small volume, and the jacking bar is very close to the saw kerf, so that the jacking can be ensured. The long stroke of the tight component 3 can achieve a better side jacking effect, and the minimum width of the ...
