Description
Technical Field
The invention relates to the field of guide rail plate fixing, in particular to a bending machine guide rail plate fixing device.
Background
The bending machine is a machine capable of bending thin plates, and mainly structurally comprises a support, a workbench and a clamping plate, wherein the workbench is arranged on the support and comprises a base and a pressing plate, the base is connected with the clamping plate through a hinge and comprises a seat shell, a coil and a cover plate, the coil is arranged in a recess of the seat shell, and the cover plate covers the top of the recess. When the clamping device is used, the coil is electrified by the lead, and the attraction is generated on the pressing plate after the coil is electrified, so that the thin plate between the pressing plate and the base is clamped. The electromagnetic force clamping is adopted, so that the pressing plate can be made into various workpiece requirements, and the workpiece with the side wall can be processed, and the operation is very simple and convenient. The bending machine is divided into a manual bending machine, a hydraulic bending machine and a numerical control bending machine. The guide rail plate is an important component in the bending machine, plays a role in supporting and guiding a moving component to move along a certain track, the moving track of the moving component has a straight line, a circle or a curve, a rolling round guide rail can be classified into a rolling thrust bearing, and a curve guide rail is rarely applied to machinery. The guide rail plate is a very important part in the machine, especially in bending machines. The machining precision of the machine tool is directly related to the precision of the guide rail plate, and once the guide rail is damaged, the maintenance is very difficult.
At present, the existing guide rail plate only fixes the bending machine frame and the guide rail plate through a simple bolt and a nut through a mounting hole, but the fixing structure is too simple and not firm enough, and the bending machine is made of common bolts with large steel weight and cannot firmly fix the guide rail plate. The bending object of the bending machine is often steel with high hardness, so that bolts for fixing the guide rail plate are easy to loosen due to the fact that the pressure applied to the guide rail plate is large during working, the precision of the bending work is reduced due to the loosening of the guide rail plate, the guide rail plate can fall off from a bending rack due to the fact that the guide rail plate loosens, and potential safety hazards exist. And the fixing effect can be lost after the ordinary bolt is slipped or the fixing is not firm enough due to a few slipped teeth, and the bolt can be broken under the action of great pressure during working, so that accidents can occur.
